Objective To explore the risk prediction model of major adverse cardiovascular events (MACE) in community patients with hypertension based on remote ambulatory blood pressure parameters. Methods From November 2023 to October 2024, 486 community patients with hypertension who received standardized management in Nanjing Medical University Affiliated to Suzhou Hospital were retrospectively selected. All patients wore remote ambulatory blood pressure monitor to obtain 24-hour ambulatory blood pressure data. Clinical data were collected and remote ambulatory blood pressure parameters [24-hour systolic blood pressure variability (SBPV), 24-hour diastolic blood pressure variability (DBPV), nighttime SBPV, nighttime DBPV, daytime SBPV, daytime DBPV] were extracted. The patients were followed up for 12 months, and were classified into MACE group (n=42) and non-MACE group (n=444) according to whether MACE occurred during follow-up. Multivariate Logistic regression analysis was adopted to screen the influencing factors for MACE. Based on the above factors, a risk prediction model was constructed and verified by receiver operating characteristic (ROC) curve. Results MACE occurred in 42 cases among 486 patients, with an incidence rate of 8.64%. Multivariate Logistic regression analysis suggested that nighttime DBPV (OR=1.119, 95%CI: 1.030-1.214), 24h-SBPV (OR=1.115, 95%CI: 1.007-1.235), nighttime SBPV (OR=1.116, 95%CI: 1.016-1.226) and diabetes mellitus (OR=2.762, 95%CI: 1.059-7.203) were independent factors for MACE (P<0.05). The model validation results revealed that the area under the ROC curve was 0.905 (95%CI: 0.854-0.956 ), and the model had a good discrimination degree. Conclusion Nighttime DBPV, 24h-SBPV, nighttime SBPV and diabetes mellitus are independent risk factors for MACE in community patients with hypertension. The clinical prediction model based on these variables exhibits certain predictive value on MACE risk.

Objective To investigate the prevalence of cognitive frailty and its associated factors among middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD) in Gusu District, Suzhou City, to provide a basis for intervention measures. Methods COPD patients managed at Pingjiang New Town Community Health Service Center in Gusu District from January to December 2024 were selected. Data were collected using the Fried Frailty Phenotype, Mini-Mental State Examination, and a general information questionnaire. Chi-square tests, one-way analysis of variance, and multivariate Logistic regression were used for data analysis. Results A total of 1 388 patients were included, with 916 males (65.99%) and 472 females (34.01%). Cognitive frailty was observed in 554 cases (prevalence: 39.91%). Univariate analysis showed significant differences in gender, education, visual impairment, hearing impairment, sleep disorders, and disease duration between the cognitive frailty and non-cognitive frailty groups (all P<0.05). Multivariate Logistic regression indicated that education was negatively associated with cognitive frailty (illiteracy OR=6.969, P<0.001; primary school OR=1.499, P=0.005), while visual impairment (OR=2.347, P<0.001), hearing impairment (OR=1.705, P<0.001), sleep disorders (OR=2.488, P<0.001), and disease duration (≤5 years OR=0.329, P<0.001; 6-10 years OR=0.487, P<0.001) were positively associated with cognitive frailty. Conclusion The prevalence of cognitive frailty among middle-aged and elderly COPD patients in Gusu District, Suzhou City, is high (39.91%). Epositively associated with cognitive frailtyducation, sensory impairments, sleep disorders, and disease duration are associated factors. Clinical attention to high-risk groups and implementation of early screening and targeted interventions are recommended.

Objective To analyze the status quo of cognitive frailty (CF) in community elderly patients with chronic obstructive pulmonary disease (COPD) and its correlation with sleep quality, anxiety and depression. Methods Elderly patients with COPD receiving health management in the center were selected from July 2023 to June 2024. The general data of patients were collected and Mini-Mental State Examination (MMSE), Fried Frailty Phenotype (FP), Pittsburgh Sleep Quality Index (PSQI) and Hospital Anxiety and Depression Scale (HADS) were used for investigation, and the above scores were analyzed. All patients were divided into CF group (n=129) and non-CF group (n=319) according to MMSE score and FP score. Univariate and multivariate logistic analyses were used to analyze the influencing factors of CF in elderly COPD patients. Results Pearson correlation analysis showed that MMSE score was significantly negatively correlated with PSQI score and HADS score in elderly COPD patients (P<0.05), and FP score was significantly positively correlated with PSQI score and HADS score (P<0.05). After logistic regression analysis, it was found that education level, marital status and sleep time were protective factors of CF in elderly COPD patients (P<0.05), and PSQI score and HADS score were risk factors of CF in elderly patients with COPD (P<0.05). Conclusion CF in community elderly COPD patients is related to sleep quality, sleep duration and anxiety and depression. It is necessary to take clinical measures to improve the sleep quality and psychological status, so as to avoid or slow down the occurrence of CF.

With the progression of global population aging,the incidence and mortality of prostate cancer have been increasing year by year,drawing widespread attention from all sectors of society.Based on the synthetic lethality strategy,the U.S.Food and Drug Administration(FDA)has successively approved multiple poly ADP-ribose polymerase(PARP)inhibitors for the treatment of metastatic castration-resistant prostate cancer(mCRPC)in recent years.This advancement has greatly stimulated the interest of researchers in novel synthetic lethal combination:the ataxia telangiectasia-mutated(ATM)gene and the ataxia telangiectasia and Rad3-related protein(ATR).In the DNA damage repair pathway,the ATM kinase primarily participates in the repair of DNA double-strand breaks,while ATR plays a crucial role in the repair of DNA single-strand breaks and exerts a positive regulatory function.ATR inhibitors are considered one of the most promising synthetic lethal targeted agents following PARP inhibitors,offering potential as a novel therapeutic option for patients with ATM gene mutations.However,current clinical research data on ATR inhibitors in the treatment of prostate cancer remain insufficient.Therefore,a deeper understanding of the synthetic lethality mechanism involving the ATM/ATR kinase combination is of crucial importance for advancing precision therapy of prostate cancer.

Objective:To investigate the correlation between 25 hydroxyvitamin D[25 (OH) D] level and sleep monitoring index in patients with severe altitude obstructive sleep apnea hypopnea syndrome (OSAHS).Methods:Sixty-six patients with severe OSAHS (AHI≥30 times/hour) diagnosed by apnea hypopnea index (AHI) who had lived at high altitude (1 800-4 193 m) for≥1 year were included in the experimental group. The patients underwent polysomnography monitoring in Sleep Medicine Center of Qinghai Red Cross Hospital from June to December 2021. In addition, healthy volunteers matched the experimental group by gender, age, ethnicity and living altitude during the same period were selected for polysomnography monitoring. Finally, 48 healthy volunteers with AHI<5 times/hour were included as the control group. 25(OH)D level and its deficiency were compared between the two groups. The experimental group was further divided into severe deficiency group [25(OH)D≤10 μg/L], the deficiency group [10 μg/L<25(OH)D≤20 μg/L] and the non-deficiency group [25(OH)D>20 μg/L] according to 25(OH)D level, and the differences of sleep parameters among the three groups were compared. Correlation analysis and multifactor linear regression analysis were performed on the factors that may affect the level of 25(OH)D in patients with severe OSAHS.Results:A total of 114 adults living on the plateau for at least one year were enrolled, including 66 in the experimental group and 48 in the control group. 25(OH)D deficiency (≤30 μg/L) was found in all the individuals included in the experimental group and the control group, and the 25(OH)D level of the two groups was [(13.13±4.05) vs (13.68±4.60) μg/L, P=0.507] and there was no significant difference in deficiency degree (all P>0.05). Within the experimental group, rapid eye movement (REM) sleep time and proportion (REM%) and sleep awakening time of 25(OH)D non-deficiency group, were significantly lower than those in severe deficiency group (all P<0.05), and sleep efficiency in 25(OH)D non-deficiency group was significantly higher than that in severe deficiency group and deficiency group (all P<0.05). Spearman correlation analysis showed that the level of 25 (OH) D in experimental group were positively correlated with serum calcium ion level ( r=0.293, P=0.017) and sleep efficiency ( r=0.309, P=0.011), and were negatively correlated with age ( r=-0.298, P=0.015), REM sleep time ( r=-0.401, P=0.001), REM% ( r=-0.421, P<0.001) and awakening time ( r=-0.362, P=0.003). Multifactor linear regression analysis suggested that serum calcium, REM sleep time and history of hypertension were the predictors of 25(OH)D level in severe OSAHS at high altitude. Conclusions:There is a correlation between sleep monitoring indexes and serum 25(OH)D level in patients with severe OSAHS at high altitude. The longer the REM sleep time, the lower the 25(OH)D level. Meanwhile, there is a certain relationship between co-morbidity hypertension and 25(OH)D level in patients with severe OSAHS at high altitude.

OBJECTIVE: To explore the impact of electroacupuncture (EA) on the AMPKα-HDAC5-HIF-1α signaling in the heart of the rats with myocardial ischemia (MI) via detecting the expressions of AMP-activated protein kinase α (AMPKα), histone deacetylase 5 (HDAC5), hypoxia inducible factor (HIF-1α) and vascular endothelial growth factor (VEGF). METHODS: Thirty-six healthy male SD rats were randomized into a sham operation group (6 rats), a sham + EA group (6 rats), a model group (12 rats) and an EA group (12 rats). We ligated the left anterior descending artery (LAD) for MI model, and exposed the heart of rats after opening the chest without ligation for the rats in the sham operation gorup and the sham + EA group. On the 2nd day after LAD ligation, EA was applied at "Neiguan" (PC 6) with 2 Hz/15 Hz and 1.5-2 mA for 30 min in the EA group and sham+EA group, once a day for 4 days. The same fixation was used in the sham operation group and the model group, without EA. Myocardial infarction area was observed by TTC staining and serum cardiac troponin T (cTnT) was detected by radioimmunoassay. The expression of VEGF mRNA was detected by real time PCR. The protein expressions of AMPKα, HDAC5, HIF-1α and VEGF were detected by western blot. RESULTS: Compared with the sham operation group, 4 days after LAD ligation, the myocardial infarction was obvious and the expression of serum cTnT increased in the model group (<0.01); and the proterin expression of HIF-1α in myocardial tissue ascended (<0.01); the expression of VEGF mRNA decreased (<0.05); the changes of the protein expressions of AMPKα、HDAC5、VEGF were not obvious (all >0.05). After EA for 4 days, the myocardial infarction area and cTnT expression decreased in the EA group (both <0.01); the VEGF mRNA and protein expressions and AMPKα, HDAC5, HIF-1α protein expressions increased (<0.05, <0.01). CONCLUSION EA could regulate the AMPKα-HDAC5-HIF-1α signaling in myocardial tissue, which may activate VEGF expression for angiogenesis signaling, reduce myocardial infarction area so as to achieve cardioprotective effect.
