    Objective  To develop a transfer learning-based classification model for sleep apnea syndrome using electrocardiogram (ECG) data, increasing its classification accuracy and clinical applicability. Methods  Based on the Apnea-ECG and MIT-BIH polysomnographic databases, with respiratory signals as input, we applied a Butterworth low-pass filter for denoising, and constructed an original data set. To address the problem of insufficient respiratory signal data, a model training method based on a transfer learning approach was proposed: first, ECG signals with a large sample size were used for model pre-training, and then they were fine-tuning for respiratory signals, finally fulfilling binary classification or multi-class classification tasks. A cascade model combining residual network and bidirectional long short-term memory network was proposed, which performed better in capturing the timing features of signals and improving classification performance. Additionally, the performance of this model was made comparative analysis with those of various classic convolutional neural networks. Results  Through comparative experiments, it was found that employing transfer learning approach could accelerate model convergence and improve the model's overall performance. Validated on the test set, the proposed cascade model demonstrated a favorable performance in both binary classification and multi-class classification tasks, achieving an accuracy of 95.43% on the binary classification task and 91.26% on the multi-class classification task. Conclusion  This study offers novel insights into the design of disease classification models under small-sample conditions, and validates the effectiveness of transfer learning in sleep apnea syndrome classification, thereby demonstrating its potential clinical utility.

    Objective  To investigate the correlation between ambulatory arterial stiffness index (AASI) and pulse pressure or blood pressure variability (BPV) in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods  A total of 205 patients specifically diagnosed with OSAHS were enrolled as research objects. They completed general data collection, and polysomnography and ambulatory blood pressure monitoring. Based on the classification of circadian blood pressure rhythm, the study population was divided into a dipper blood pressure group (n=92) and a nondipper blood pressure group (n=113). We compared the general clinical characteristics between the two groups as well as the correlation between AASI and ambulatory blood pressure parameters by using Pearson correlation analysis. Multiple linear regression analysis was applied to explore the relationship between AASI and pulse pressure or BPV. Results   The AASI of the non-dipper blood pressure group was significantly higher than that of the dipper blood pressure group (P<0.01). AASI was positively correlated with age, 24-hour mean systolic blood pressure and pulse pressure, while it was negatively correlated with 24-hour mean diastolic blood pressure, and the decline ratio of nocturnal systolic and diastolic blood pressure (all P<0.05). Pulse pressure was associated with AASI if BPV remained constant (P<0.05). Conclusion  The AASI of OSAHS patients demonstrates an association with pulse pressure and age. AASI may serve as a promising indicator reflecting arterial stiffness.

    Objective  To explore the association between obstructive sleep apnea syndrome (OSAS) and heart rate variability (HRV) or circadian rhythm of blood pressure in hypertensives. Methods  A total of 102 inpatients and outpatients with hypertension were selected in our study, and they were divided into hypertension with OSAS group (55 cases) and primary hypertension group (47 cases). This study enrolled 50 concurrent healthy subjects (all with organic diseases excluded, and without comorbidities of hypertension or OSAS) as a control group. We compared and analyzed the HRV time-domain indexes of SDANN and rMSSD, and HRV frequency-domain indexes of LF and HF, as well as apnea hypopnea index (AHI), nocturnal mean oxygen saturation level, daytime and nocturnal blood pressure levels, and changes of circadian blood pressure rhythm. Results  The nocturnal minimum saturation of arterial oxygen (SaO2) and nocturnal mean SaO2 of patients in the hypertension with OSAS group were both lower than those of patients in the primary hypertension group, while AHI was higher (all P<0.05). There were no statistically significant differences in the above sleep respiratory parameters between the primary hypertension group and the control group (all P>0.05). There were no statistically significant differences in the daytime and nocturnal blood pressure levels, and the incidence of non-dipper pattern between the primary hypertension group and the control group (all P>0.05). Comparisons of the aforementioned parameters between the hypertension with OSAS group and the control group all demonstrated statistically significant differences (all P<0.01). The hypertension with OSAS group exhibited a significantly higher prevalence of non-dipper circadian blood pressure rhythm compared to the other two groups (all P<0.05). Compared to the other two groups, the values of SDANN and LF of patients in the hypertension with OSAS group were higher, while the values of rMSSD and HF were lower (all P<0.05). There were no statistically significant differences in the LF, HF, SDANN and rMSSD values between the primary hypertension group and the control group (all P>0.05). Conclusion  Patients with OSAS demonstrate increased nocturnal blood pressure level, enhanced sympathetic nerve tension and decreased vagus nerve tension, as well as increased risk of cardiovascular and cerebrovascular diseases.

    Magnetocardiography ( MCG), a technique that measures the weak magnetic field generated by human electrophysiological activities, provides non-invasive, ionizing-radiation-free functional information.Compared with traditional structural imaging techniques, MCG can capture functional changes in the early stages of diseases, making it particularly suitable for early screening and disease progression assessment. In recent years,rapid advancements in quantum magnetic sensors, magnetic shielding, and active compensation technologies have enabled MCG to overcome the limitations of low-temperature superconductivity and magnetically shielded rooms gradually, developing in the direction of greater convenience and lower cost. However, despite its significant potential in clinical applications such as chest pain triage, coronary heart disease screening, and myocardial ischemia assessment, the clinical translation of MCG still faces challenges including insufficient specificity and lack of standardization. Furthermore, variations in equipment and signal processing methods lead to low comparability among research findings. This article reviews the development history and current application status of MCG technology, synthesizes the research progress of our team over the past three years, discusses the bottlenecks in applying MCG across different clinical settings, and proposes that future research should focus on areas such as physical mechanisms, feature interpretability, establishing quantitative relationships between diseases, and improving clinical diagnostic specificity. These efforts aim to promote the standardization of MCG, and advance its research and application in the fields of cardiology, neurology, oncology, and traditional Chinese medicine.

    Objective  To investigate the impact of long non-coding RNA ZFAS1 (lncZFAS1) on the initiation and progression of cardiomyocyte fibrosis. Methods  HL-1 mouse cardiac myocytes were induced by transforming growth factor-β (TGF-β) to establish a cardiomyocyte fibrosis model. LncZFAS1 overexpression vectors or small interfering RNA (siRNA) were transfected into the model. Protein levels of α-smooth muscle actin (α-SMA) and collagen Ⅰ were detected by western blotting; lncZFAS1 overexpression and interference fragments were transfected into the cardiomyocyte fibrotic model. The transcriptional level of lncZFAS1 was measured via real-time quantitative PCR. Cell proliferation viability was assessed using the CCK-8 assay, apoptosis rate was analyzed by flow cytometry, and LC3 autophagy puncta formation was examined using cellular immunofluorescence. Results  Compared with the control group, the TGF-β induction group showed significantly increased protein expression of α-SMA, collagen Ⅰ and LC3 B, significantly decreased p62 protein expression, elevated lncZFAS1 expression, enhanced cell viability and autophagy puncta formation, and reduced apoptosis rate (all P<0.05). After interfering with lncZFAS1 in the model, it showed a decrease in the expression level of lncZFAS1, a decrease in cell viability and the number of autophagy puncta, an increase of apoptosis rate and expression of p62 protein, and a decrease in the expression of LC3 B protein, all with statistically significant differences (all P<0.05). However, after overexpression of lncZFAS1, the opposite results were presented. Conclusion  LncZFAS1 promotes the initiation and progression of cardiomyocyte fibrosis by regulating cellular autophagy. Targeted inhibition of lncZFAS1 may provide a novel therapeutic strategy for delaying the progression of cardiovascular diseases.

    Objective  To investigate the association between homocysteine (Hcy) and the C677T gene polymorphism in its key metabolic enzyme, methylenetetrahydrofolate reductase (MTHFR), and the complications of hypertension, type 2 diabetes mellitus and atherosclerosis in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods  A total of 85 OSAHS patients and 77 non-OSAHS patients were enrolled. The genotypes, and levels of serum Hcy, fasting blood glucose and hemoglobin Alc of all subjects were detected, while cervical vascular ultrasound was performed simultaneously. Hcy≥10 μmol/L was defined as hyperhomocysteinemia (HHcy). The serum Hcy levels were compared among patients with different genotypes. The Hcy levels, MTHFR C677T gene polymorphism, and C/T allele frequencies were compared among an OSAHS with complications group, a pure OSAHS group, and a control group (without OSAHS or complications). Then, multivariate binary Logistic regression analysis was performed to identify independent risk factors for complications in OSAHS patients with confounding factors adjusted. Results  The Hcy levels in the patients with CC, CT and TT genotypes were 10.11 (9.15, 11.07), 10.86 (9.58, 11.10) and 15.81 (11.43, 50.76) μmol/L, respectively. Hcy level in the patients with TT genotype was significantly higher than that in the cases with CT or CC genotypes (both P<0.05). The Hcy levels of the OSAHS with complications group, the pure OSAHS group, and the control group were 11.16 (10.05, 13.80), 9.88 (9.31, 11.41), and 10.38 (9.29, 11.34) μmol/L, respectively. The Hcy level of the OSAHS with complications group was significantly higher than that of the pure OSAHS group (P<0.05). There were no statistically significant differences in gene polymorphism or C/T allele frequency among the three groups. After adjusting for confounding factors, it revealed that HHcy was an independent risk factor for concurrent complications in OSAHS patients, and the odds ratio (95% confidence interval) was 4.682 (1.261-17.380). Conclusion  The MTHFR C677T gene polymorphism affects serum Hcy level. HHcy is an independent risk factor for concurrent complications in OSAHS patients, however, neither the MTHFR C677T gene polymorphism nor the C/T allele frequency were associated with complications in OSAHS patients.

    Objective  To explore the relationship between epicardial fat thickness (EFT), serum secreted frizzled-related protein 5 (SFRP5), wingless-type MMTV integration site family member 5a (Wnt5a), and in-stent restenosis (ISR) in patients with acute ST-segment elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI). MethodsA total of 128 STEMI patients who had undergone emergency PCI were enrolled. After a 12-month follow-up, they were divided into a non-ISR group (80 cases) and an ISR group (48 cases) based on coronary angiography results. The general data between the two groups were compared, as well as the EFT before discharge and 1 month after surgery, and the serum levels of SFRP5 and Wnt5a measured before surgery and 1 month postoperatively. The differences in the levels of these indicators among patients with varying degrees of coronary artery lesions were also examined. Pearson correlation analysis was used to evaluate the association between EFT and serum levels of SFRP5 and Wnt5a 1 month after surgery. Multivariate Logistic regression analysis was applied to identify the risk factors of ISR in STEMI patients after PCI. ROC curve analysis was used to assess the predictive value of EFT, and serum SFRP5 and Wnt5a levels for ISR. ResultsThe EFT values of the ISR group before discharge and 1 month after surgery were both greater than those of the non-ISR group (all P<0.01). The serum SFRP5 level of the ISR group was lower than that of the non-ISR group 1 month after surgery, while the serum Wnt5a level was higher (all P<0.01). Compared to pre-operative levels, serum SFRP5 levels increased 1 month after surgery in the non-ISR group but decreased in the ISR group (both P<005). Serum Wnt5a levels showed a mild increase 1 month after surgery compared to pre-operative levels in the non-ISR group, but increased significantly in the ISR group (both P<0.05). The serum SFRP5 level 1 month after surgery was significantly lower in the three-vessel disease group than that in the single- or two-vessel disease groups (P<0.05). EFT 1 month after surgery showed a negative correlation with SFRP5 and a positive correlation with Wnt5a. Both univariate Logistic regression analysis and Logistic regression analysis adjusted for factors such as age and BMI demonstrated that EFT, and serum SFRP5 and Wnt5a levels 1 month after surgery were independent influencing factors for ISR. ROC curve analysis revealed that the combination of these three markers yielded an AUC value of 0.906, which was higher than that of detection with any single indicator. Conclusion  Increased EFT, decreased serum SFRP5, and elevated serum Wnt5a 1 month after surgery are closely related to ISR in STEMI patients after PCI. Early detection of these markers facilitates the prediction of ISR, and the combined detection offers superior predictive value.

    Objective  To investigate the regulatory role and underlying mechanism of circular RNA circHECTD1, a potential diagnostic biomarker for coronary heart disease (CHD), in macrophage polarization. Methods  A lipopolysaccharide-induced M1 macrophage polarization model was used to simulate a low-grade inflammatory response process. Quantitative real-time PCR (qRT-PCR) was employed to detect the expression levels of circHECTD1 and N6-methyladenosine (m6A) regulatory factors. Western blotting was performed to measure the expression of M1 phenotype marker proteins and autophagyrelated proteins. Intracellular reactive oxygen species (ROS) levels were assessed by flow cytometry. Results  Silencing circHECTD1 significantly reduced the expression of M1 phenotype-related proteins and inflammatory cytokines, decreased ROS levels, and enhanced cellular autophagy. Disordered expression of multiple m6A regulatory factors was observed in both the cellular model and peripheral blood mononuclear cells (PBMCs) from CHD patients. Significant differences in the expression levels of multiple m6A methylation regulators were identified between CHD and control groups, suggesting their potential value in CHD diagnosis. Univariate and multivariate Logistic regression analysis revealed that the m6A regulators of METTL3, METTL14, ALKBH5, and YTHDC2 were significantly associated with CHD risk. Further analysis showed that the expression of METTL14 and ALKBH5 were significantly upregulated in advanced stages of atherosclerosis. The expression level of circHECTD1 significantly correlated with FTO, YTHDF3, ALKBH5, METTL3, METTL14, and YTHDF2. In vitro experiment results demonstrated that silencing METTL14 and ALKBH5 markedly downregulated circHECTD1 expression, indicating that METTL14 and ALKBH5 positively regulated circHECTD1 expression. Conclusion  Dysregulation of m6A regulatory factors may be closely associated with the occurrence and development of CHD, potentially mediated through the regulation of circHECTD1 expression and function.

    Objective  To investigate the application of dexmedetomidine via programmed intermittent epidural bolus (PIEB) for labor analgesia in hypertensive disorder of pregnancy (HDP) parturients, and its effect on umbilical artery flow and maternal-fetal outcomes. Methods  This study was a prospective, and double-blind clinical study. A hundred HDP parturients who had undergone labor analgesia were selected, and randomly divided into group A and B, each with 50 cases by random number table method. Group A received continuous epidural infusion, while group B received PIEB. Based on the visual analogue scale (VAS), the degree of pain before analgesia (T0), 1 h after analgesia (T1), 2 h after analgesia (T2), and at the time of complete cervical dilation (T3) were compared between the two groups of parturients. We simultaneously recorded the changes of umbilical artery flow at T0-T2 [umbilical artery resistance index (RI), pulsation index (PI) and the ratio of maximum systolic blood velocity to diastolic blood velocity (S/D)], maternal vital signs at T0 and T1 [heart rate (HR) and mean arterial pressure (MAP)], and the occurrence of adverse maternalfetal outcomes and adverse reactions in the two groups. ResultsComparison of VAS scores at different time points within each group showed statistically significant differences (all P<0.01). VAS scores at T1, T2 and T3 were all lower than that at T0(all P<0.05). VAS score of the group B at T2 was lower than that at T1(P<0.05). VAS score of the group B at T3 was lower than that at T2(P<0.05), while the VAS score of the group B at T2 or T3 were both lower than that of the group A (both P<0.01). There was no statistically significant difference in VAS score between the two groups at T0 and T1(P>0.05). Statistically significant differences were observed in RI, PI, and S/D values across different time points within both groups (all P<0.01). At T1 and T2, the RI, PI, and S/D ratio of fetuses in both groups all decreased compared to T0(all P<0.05). At T2, the RI, PI and S/D ratio of fetuses in both groups were all lower than those at T1(all P<0.05). There were no statistically significant differences in fetal RI, PI, and S/D ratio between the two groups at T0, T1 or T2(all P>0.05). At T1, HR and MAP in the two groups were both lower than those at T0(both P<0.05), while HR and MAP of the group B were both lower than those of the group A (both P<0.05). There were no statistically significant differences in the total incidences of adverse maternal-fetal outcomes or drug adverse reactions between the two groups (all P>0.05). Conclusion  Dexmedetomidine via PIEB could improve the effect of labor analgesia in HDP parturients, and maintain stability of fetal umbilical hemodynamics and maternal vital signs, with a high safety.

    Objective  To explore the influence of colonization factor (CF) on the adhesion of Jiulian probiotics to intestinal mucosal epithelial cells, and the efficacy of Jiulian probiotics combined with CF in treating intestinal dysfunction. Methods  Twenty patients with intestinal dysfunction were selected. Based on whether the Jiulian probiotics were co-cultured with intestinal mucosal epithelial cells in combination with CF, they were divided into an experimental group (the Jiulian probiotic suspension was co-cultured with intestinal mucosal epithelial cells in combination with CF) and a control group (only the Jiulian probiotic suspension was co-cultured with intestinal mucosal epithelial cells). Observation was conducted using a self-controlled approach. The Jiulian probiotics that adhered to the intestinal mucosal epithelial cells were extracted separately 4 and 12 hours after co-cultivation; the number of formed colonies was counted, and the effect of CF on promoting the adhesion of the probiotics to the intestinal mucosal epithelial cells was analyzed. According to the gastrointestinal symptom rating scale (GSRS) scores, the curative effect was assessed between the two groups. Results  The Jiulian probiotics adherent to cells, harvested from the experimental group after 4 hours of co-cultivation, formed significantly more colonies than those harvested from the control group after 24-hour of cultivation (P<0.05), while the formed colonies after 12 hours of cocultivation were significantly more than those harvested from the control group (P<0.01). After the combination treatment, the GSRS score of the patients was significantly lower than that before the treatment (P<0.01), while symptoms such as abdominal pain and diarrhea were significantly improved. Conclusion  CF could promote the adhesion of Jiulian probiotics to intestinal mucosal epithelial cells. Probiotics combined with CF may become one of effective methods for treating intestinal dysfunction.

    Objective  To investigate autonomic function changes in patients with neurally mediated syncope. Methods  We collected the clinical data of patients presenting with syncope or presyncope. According to the results of head-up tilt test (HUTT), they were divided into an HUTT positive (mixed type) group and an HUTT negative group, each with 53 cases. Each heart rate variability (HRV) index of the two groups were comparatively analyzed before HUTT and during the testing. Results  Before the testing, there were no statistically significant differences in the HRV time-domain indexes of SDNN, SDANN, SDNN index, rMSSD, pNN50, and TINN between the two groups (all P>005); there were also no statistically significant differences in the HRV frequency-domain indexes of LF, HF and LF/HF between the two groups (all P>0.05). During the process of HUTT, if the during-HUTT indexes were compared between the two groups, it revealed that rMSSD value of the HUTT positive (mixed type) group was significantly higher than that of the HUTT negative group (P<0.05). Conclusion  Compared to pre-HUTT HRV indexes, during-HUTT HRV indexes demonstrate greater clinical significance.

    ObjectiveTo investigate the anesthesia effect of dexmedetomidine combined with esketamine in elderly patients with orthopedic lower extremity surgery. MethodsEighty elderly patients undergoing orthopedic lower extremity surgery were randomly divided into two groups, with 40 cases in each group. The control group was given esketamine for anesthesia, while the drug combination group was given dexmedetomidine combined with esketamine for anesthesia. The anesthesia indexes between the two groups of patients were compared, as well as the vital signs, sedation degree, pain degree, and cognitive status before operation (T0), 6 hours after operation (T1), 12 hours after operation (T2) and 48 hours after operation (T3). The occurrence of adverse reactions was also compared between the two groups. ResultsThe recovery time of spontaneous respiration, anesthesia recovery time, orientation recovery time and extubation time in the drug combination group were all significantly shorter than those in the control group (P<0.05). There were statistically significant differences in heart rate and mean arterial pressure (MAP) at different times in the control group (P<0.01), but there was no statistically significant difference in blood oxygen saturation (SpO2) at different times in the control group (P>0.05). There were no statistically significant differences in heart rate, MAP and SpO2 at different times in the drug combination group (P>0.05). At T1, T2 and T3, heart rate and MAP of the drug combination group were both lower than those of the control group (all P<0.01). There were statistically significant differences in sedation scores at different times in the control group (P<0.01), while there were no statistically significant differences in sedation scores at different times in the drug combination group (all P>0.05). At different times, the sedation scores of the drug combination group were all significantly higher than those of the control group (all P<0.01). There were statistically significant differences in pain scores at different times between the two groups (P<0.01). At T1, T2 and T3, the pain scores of the drug combination group were all significantly lower than those of the control group (all P<0.01). There were statistically significant differences in mini-mental state examination (MMSE) scores between the two groups at different times (all P<0.01). At 24 hours after the operation, MMSE score of the drug combination group was significantly higher than that of the control group (P<0.01); there was no statistically significant difference in MMSE score between the two groups at 72 h, 1 week and 1 month after the operation (all P>0.05). The total incidence of adverse reactions in the drug combination group was 5.00%, significantly lower than 22.50% in the control group (P<0.05). Conclusion  Compared to anesthesia using esketamine alone, dexmedetomidine combined with esketamine is safe and effective for elderly patients with orthopedic lower extremity surgery. It could significantly shorten the recovery time of anesthesia, stabilize perioperative hemodynamics, improve the effect of sedation and analgesia, and reduce the risk of cognitive dysfunction 24 hours after surgery with lower incidence rates of adverse reactions.

    Complete right bundle branch block (CRBBB) is a common electrocardiographic abnormality observed across all age groups. It is characterized by delayed conduction or anatomical rupture in the right bundle branch, resulting in delayed depolarization of the right ventricle after the left ventricle. This conduction disorder often coexists with various cardiovascular diseases, such as atrial fibrillation, coronary heart disease, heart failure, and cardiomyopathies, with its incidence varying significantly among different populations. Historically, CRBBB was usually considered to have limited clinical significance. However, recent studies indicate that it has important clinical significance not only in patients with structural heart diseases but also in newonset cases, general population, and athletes.

    Objective  To investigate the efficacy of sugemalimab combined with cisplatin plus paclitaxel regimen in patients with advanced nonsmall cell lung cancer (NSCLC). Methods  Seventy patients with advanced NSCLC were selected as study objects; by using a randomized single-blind method, they were assigned into a control group and a sugemalimab group, with 35 cases in each group. The control group received cisplatin plus paclitaxel therapy, while the sugemalimab group adopted sugemalimab in addition to the control group's regimen. The short-term efficacy, occurrence of adverse reactions, prognosis, levels of cytokeratin 19 fragment antigen 21-1 (CYFRA21-1), carcinoembryonic antigen, squamous cell carcinoma antigen (SCC-Ag), carbohydrate antigen 125 (CA125) and carbohydrate antigen 50 (CA50), and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTCQLQ-C30) scores were compared between the two groups before and after treatment. Results   After three treatment cycles, the sugemalimab group showed a significantly higher disease control rate compared to the control group [80.00% (28/35) vs. 57.14% (20/35), P<0.05]; the levels of CYFRA21-1, carcinoembryonic antigen, SCC-Ag, CA125, and CA50 were all significantly lower in the sugemalimab group than those in the control group (all P<0.01). The sugemalimab group also exhibited significantly lower EORTCQLQ-C30 symptom scores compared to the control group, with significantly higher functional and overall quality of life scores (all P<0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (P>0.05). After one year of follow-up, the survival rate was significantly higher in the sugemalimab group than that in the control group [73.53% (25/34) vs. 51.52% (17/33), P<0.05]. Conclusion  Combining sugemalimab with the cisplatin plus paclitaxel regimen improves treatment efficacy in patients with advanced NSCLC, further reduces tumor marker levels, increases quality of life and survival rates, and demonstrates a favorable safety.

    Objective To analyze the therapeutic effect of low-flow oxygen inhalation in elderly patients with hypertension complicated by obstructive sleep apnea syndrome (OSAS). Methods A total of 175 elderly patients with hypertension and OSAS were selected as study subjects. All patients received conventional antihypertensive medication as recommended by guidelines. Those receiving continuous positive airway pressure (CPAP) therapy, low-flow oxygen inhalation therapy, and no corresponding intervention were assigned to a CPAP group (55 cases), a low-flow oxygen group (60 cases), and a control group (60 cases), respectively. Clinical data were collected, including body mass index, waist circumference, underlying diseases, laboratory test results and color Doppler echocardiography parameters, as well as systolic/diastolic blood pressure, Epworth sleepiness scale (ESS) scores, nocturnal minimum saturation of peripheral oxygen (SpO2), and apnea hypopnea index (AHI) before and after intervention (3 months of treatment). ResultsBlood pressure control and respiratory parameters in the low-flow oxygen group both improved significantly after oxygen inhalation (both P<0.05). After 3 months of follow-up, the nocturnal minimum SpO2 in both the low-flow oxygen and CPAP groups increased significantly compared with pre-intervention levels (both P<0.01). There was statistically significant difference in nocturnal minimum SpO2 after intervention among the three groups (P<0.01). After pharmacotherapy or intervention, systolic and diastolic blood pressures both decreased significantly in all the three groups compared with pre-intervention levels (all P<0.05), and post-intervention differences in systolic and diastolic blood pressures among the three groups were statistically significant (all P<0.05). Compared with baseline, both the low-flow oxygen group and the CPAP group demonstrated significant reduction in ESS score and AHI after the intervention (both P<0.05). Conclusion Low-flow oxygen inhalation therapy in elderly patients with hypertension and OSAS could partially improve sleep respiratory parameters, increase nocturnal SpO2, and help to increase the compliance rate of blood pressure control, reduce the use of antihypertensive medication and alleviate economic burden.

    Objective  By comparing the characteristics of chest lead electrocardiogram (ECG) indicators related to premature ventricular contraction (PVC), to explore the ECG indicators that can identify the origin point of outflow tract PVC more accurately. Methods  Seventy-eight patients with outflow tract PVC who had received successful radiofrequency catheter ablation were retrospectively analyzed. Among them, 52 cases of PVC were originated from the right ventricular outflow tract (RVOT), while 26 cases were originated from the left ventricular outflow tract (LVOT). The V2 transition index, SV2/RV3 index, RV1 wave duration index (RdV1/QRSdV1) and RV1/SV1 amplitude index were measured respectively. Each parameter and its diagnostic efficacy in differentiating outflow tract PVC were compared, and analyzed between the two groups. Results  There were no statistically significant differences in clinical features including age, sex, body mass index, smoking history, drinking history, complicated hypertension, complicated diabetes, cardiac structural and functional parameters, preoperative ventricular arrhythmia burden by 24-hour ambulatory electrocardiography (AECG), and preoperative anti-arrhythmic drug types between the two groups (all P>0.05). V2 transition index, SV2/RV3 index, RdV1/QRSdV1 and RV1/SV1 amplitude index were all significantly different between the two groups (all P<0.01). ROC analysis and decision curve analysis (DCA) were used to explore the diagnostic performance of each parameter in distinguishing the origin of outflow tract PVC. The AUC value of V2 transition index was 0.837, its optimal cut-off value was 0.76, and the sensitivity, specificity and accuracy rate were separately 0.718, 1.000 and 0.780. The AUC value of SV2/RV3 index was 0.859, its optimal cut-off value was 3.48, and the sensitivity, specificity and optimal accuracy rate were separately 0.718, 1.000 and 0.780. The AUC value of RdV1/QRSdV1 was 0.741, its optimal cut-off value was 0.35, and the sensitivity, specificity and accuracy rate were separately 0.487, 1.000 and 0.600. The AUC value of RV1/SV1 amplitude index was 0.836, its optimal cut-off value was 0.34, and the sensitivity, specificity and accuracy rate were separately 0.692, 0.909 and 0.740. V2 transitional index and SV2/RV3 index had higher diagnostic predictive value. DCA results showed that SV2/RV3 index demonstrated the highest net benefit. Based on age, sex, body mass index, smoking and drinking history, hypertension, diabetes, cardiac structural and functional parameters, preoperative ventricular arrhythmia burden, and the use of preoperative anti-arrhythmic drugs, we constructed a basic model. After adding V2 transition index to it, the differentiation performance of the model was significantly improved (C-index was 0.924, 95% confidence interval: 0.851-0.996, P=0.003); after adding SV2/RV3 index, its differentiation performance was further improved (C-index was 0.953, 95% confidence interval: 0.905-1.000, P<0.001). Conclusion  V2 transition index and SV2/RV3 index have relatively high differentiation value in locating the origin of outflow tract PVC, especially SV2/RV3 index demonstrating very high clinical utility value for PVC migrating in lead V2-V3.

    Objective  To systematically analyze the clinical characteristics of septic patients complicated by myocardial infarction (MI), evaluate its impact on in-hospital mortality, and to explore related influencing factors and prognostic indicators. Methods  Based on the MIMIC-Ⅳ v2.0 database, a total of 12 838 adult septic patients meeting the Sepsis-3 diagnostic criteria were included. They were divided into two groups according to the presence of MI: a sepsis with MI group (n=2 236) and a sepsis-alone group (n=10 602). Demographic data, clinical indicators, and outcomes were compared between the two groups. Multivariate Logistic regression and random forest models were used to identify key predictors of in-hospital mortality, and subgroup stratification analysis was performed. Results  Septic patients with MI were older, had a higher proportion of males, a significantly higher prevalence of diabetes and chronic obstructive pulmonary disease (COPD), and higher APACHE-Ⅲ and SAPS-Ⅱ scores than those in the sepsis-alone group (all P<0.05). The in-hospital mortality rate in the sepsis with MI group was 25.2%, significantly higher than that in the sepsis-alone group (19.9%, P<0.001). Multivariate Logistic regression analysis showed that MI was an independent risk factor of in-hospital mortality (OR=1.26, 95% CI 1.11-1.43). Subgroup analysis revealed that in patients with MI, COPD, hypoalbuminemia, and low platelet count were significantly associated with an increased risk of death, while diabetes showed a protective effect in patients without MI. The random forest model further validated the importance of these variables in predicting mortality risk. Additionally, statin use was associated with reduced 90-day mortality in septic patients with MI. Conclusion  MI significantly aggravates the condition of septic patients and increases the risk of in-hospital mortality, highlighting the importance of early risk stratification and intervention. Predictive models combining multivariate statistics and machine learning may facilitate more accurate individualized prognostic assessment.

    Objective  To study the clinical efficacy and safety of radiofrequency catheter ablation for atrial fibrillation (AF) by domestic minimally invasive Columbus  system. Methods  A total of 26 patients with AF who had undergone radiofrequency catheter ablation with Columbus  system and its supporting catheter were successively selected. The immediate success rate of surgery, intraoperative related parameters and surgery-related complications were recorded, while the recurrence of AF and the occurrence of adverse events were observed during follow-up. Results  The enrolled 26 patients were all paroxysmal AF. Pulmonary vein isolation was successfully achieved during operation, and there were no complications related to radiofrequency catheter ablation during perioperative period. During a mean follow-up of (5.92±1.94) months, AF recurred in 5 of 26 patients (19.23%). No serious adverse events such as embolism, bleeding, atrial esophageal fistula, or death occurred during the follow-up. Conclusion  Radiofrequency catheter ablation for AF by using domestic minimally invasive Columbus system is clinically feasible, with satisfactory short-term efficacy and safety.

    Objective To explore the clinical performance of non-invasive prenatal testing (NIPT) in screening for fetal chromosomal copy number variations (CNVs). Methods In this retrospective cohort study, 196 high-risk NIPT samples were analyzed. The results of chromosomal karyotyping analysis or chromosomal microarray analysis (CMA) were compared. The positive rate and positive predictive value (PPV) of fetal CNVs, and other clinical data were screened by NIPT, so as to assess the detection value of NIPT for fetal CNVs. Results A total of 20 378 NIPT samples were tested. Among the 196 high-risk samples, 54 were CNVs, with a screening positive rate of 0.265%. Forty-six pregnant women underwent interventional prenatal diagnosis, among whom there were 21 cases confirmed with CNVs including 13 cases with pathogenic variations, 3 cases with likely pathogenic variations, and 5 cases with variations of unknown significance. The PPV of NIPT for screening CNVs was 45.65%. Seventeen cases of microdeletion CNVs and 36 cases of microduplication CNVs were screened out by NIPT, and 1 case was microdeletion combined with microduplication CNVs, accounting for 31.48% (17/54), 66.67% (36/54), and 1.85% (1/54), respectively. The corresponding PPVs were 64.29%, 35.48% and 100.00%, respectively. Statistical analysis showed that there were no statistically significant differences in the positive rate and PPV of NIPT for screening microdeletion CNVs and microduplication CNVs (all P>0.05). Conclusion NIPT demonstrates relatively high positive rate and PPV for screening fetal CNVs. Interventional prenatal diagnosis should be recommended for those with high-risk of CNVs by NIPT. NIPT combined with chromosomal karyotyping analysis and CMA could provide precise genetic counseling and guidance for clinical practice.

    Depression is a mental disorder characterized by high prevalence and substantial disease burden. Its pathophysiological process is closely associated with dysfunction of the autonomic nervous system. Heart rate variability (HRV), a non-invasive and quantitative indicator for assessing autonomic nervous function, provides a crucial window into revealing the pathophysiological mechanisms of depression. This article systematically reviews the HRV characteristics in patients with depression, related pathophysiological mechanisms, challenges in practical measurement, and its applications in diagnosis and treatment, aiming to explore the potential value and application prospects of HRV as a biomarker for precision management in depression.

    Objective  To evaluate the short-term efficacy of proximal gastrectomy combined with tubular gastroesophageal circular anastomosis in the treatment of earlystage esophagogastric junction adenocarcinoma (EGJA). Methods  Clinical data of 7 patients with early-stage EGJA who had undergone this procedure were retrospectively analyzed. Parameters included baseline characteristics, perioperative indicators, and follow-up outcomes, with a focus on perioperative status, complication incidence, postoperative nutritional status and gastroesophageal reflux. Results  All the 7 patients successfully underwent laparoscopy-assisted proximal gastrectomy with tubular gastroesophageal circular anastomosis. The mean operative time was (227.1±51.9) minutes, the mean anastomosis time was (54.4±10.0) minutes, and the mean intraoperative blood loss was (47.1±28.7) mL. The mean time to first flatus was (3.3±1.3) days, while the mean hospital stay was (21.1±7.6) days. After the procedure, one patient developed an anastomotic leak, with no other complications recorded. At the 6-month follow-up, the mean serum albumin level was (39.2±3.4) g/L, the mean hemoglobin level was (124.6±13.8) g/L, and the mean gastroesophageal reflux disease questionnaire score was (3.1±0.9) points. Both gastroscopy and upper gastrointestinal radiography with iodinated contrast studies showed no significant signs of reflux esophagitis. Conclusion  Laparoscopic proximal gastrectomy with tubular gastroesophageal circular anastomosis is a safe and feasible approach for patients with early-stage EGJA. Initial findings suggest that this technique demonstrates reliable anti-reflux efficacy, helps to reduce the risk of postoperative reflux esophagitis, and contributes to improved quality of life after surgery.

    Objective  To investigate the risk factors associated with calcific aortic valve disease (CAVD), and to provide a basis for clinical guidance and intervention. Methods  A retrospective analysis was conducted on 184 patients diagnosed with CAVD by echocardiography. Clinical data and information on comorbidities were collected, and 217 subjects with normal aortic valve morphology were selected as a control group. Multivariate Logistic regression analysis was used to identify independent risk factors and related predisposing factors for CAVD. Results  Advanced age, coronary heart disease, heart failure, renal insufficiency, or cerebral infarction were associated with a higher risk of CAVD. Among these, advanced age and renal insufficiency were independent risk factors for CAVD. Analysis of laboratory indicators suggested that lipoprotein(a) may be an independent risk factor for CAVD, and monitoring this indicator could help identify high-risk populations. ConclusionThe occurrence of CAVD is closely related to advanced age and renal insufficiency, and elevated lipoprotein(a) may also be involved in its pathogenesis.
