Objective:To investigate the prevalence of abdominal aortic aneurysm (AAA) and analyze its risk factors among male residents in nursing homes in Shuangliu district, Chengdu.Methods:A cross-sectional survey was conducted from 2014 to 2023 among male permanent residents aged 65 years or older from 24 nursing homes in Shuangliu district, Chengdu. The prevalence of AAA was calculated. Univariate analysis and multivariate logistic regression analysis were used to identify risk factors for AAA.Results:Among 3 092 elderly males screened, 98 cases of AAA were detected, with a prevalence rate of 3.17%. The mean age of AAA patients was (73.9±6.9)years, with height of (157.79±5.87)cm and weight of (57.90±9.45)kg. Univariate analysis showed that hypertension, systolic blood pressure, cardiovascular disease, cerebrovascular disease, smoking, and alcohol consumption were significantly associated with AAA prevalence (all P<0.05). Multivariate logistic regression analysis identified cerebrovascular disease ( OR=7.201), cardiovascular disease ( OR=12.412), smoking ( OR=2.887), and alcohol consumption ( OR=1.675) as independent risk factors for AAA in this population (all P<0.05). Conclusions:The prevalence of AAA among male nursing home residents in Shuangliu district, Chengdu is 3.17%. The main risk factors include alcohol consumption, cardiovascular disease, cerebrovascular disease, and smoking.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To evaluate the pulmonary protective effect of individualized positive end-expiratory pressure (PEEP) ventilation guided by driving pressure in patients undergoing rib fracture surgery.Methods:In this prospective randomized controlled trial, 80 American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ patients of either sex, aged 18-64 yr, with a body mass index of 19-28 kg/m 2, who underwent elective open reduction and internal fixation of unilateral rib fractures at the Third Hospital of Hebei Medical University from March to October 2024, were selected and divided into 2 groups ( n=40 each) by the random number table method: fixed PEEP ventilation group (group C) and driving pressure-guided individualized PEEP ventilation group (group DP). Group C adopted the ventilation strategy of fixed PEEP with 5 cmH 2O. Group DP adopted the ventilation strategy guided by the driving pressure: PEEP was titrated from 10 cmH 2O, being gradually decreased to 3 cmH 2O at intervals of 1 cmH 2O. Each PEEP level was maintained for 10 respiratory cycles, and the driving pressure of the last cycle was calculated, and the PEEP that could achieve the lowest driving pressure was selected and applied. Lung ultrasound examinations were performed immediately after entering the operating room (T 0) and at 30 min after entering the anesthesia recovery room (T 3), and the lung ultrasound score was recorded. The occurrence of severe postoperative pulmonary complications within 7 days was recorded. Arterial blood gas analysis was performed at T 0, 1 h after PEEP setting (T 1), at the end of suture at the surgical site (T 2) and at T 3, and the oxygenation index was calculated. The peak airway pressure, PEEP and driving pressure were recorded at T 1 and T 2. The duration of the indwelling thoracic drainage tube use and length of postoperative hospital stay were recorded. Results:The incidence of severe postoperative pulmonary complications within 7 days after surgery was 28%(11/40) in group C and 10% in group DP, and the incidence was significantly lower in DP group than in C group ( P<0.05). Compared with group C, the lung ultrasund score was significantly decreased at T 3, the oxygenation index was increased at T 1-3, the PEEP was increased and the driving pressure was decreased at T 1-2, and the length of postoperative hospital stay was shortened in group DP ( P<0.05). Conclusions:Driving pressure-guided individualized PEEP ventilation can decrease the risk of severe postoperative pulmonary complications, alleviate postoperative lung injury and provide a certain degree of lung protection in patients undergoing rib fracture surgery.

Ischemic stroke（IS） is a common cerebrovascular disease in clinics，with a high disability rate. In recent years，the incidence of IS has gradually increased，especially in young people，which seriously affects the physical and mental health and quality of life of patients. Western medicine has made some progress in the treatment of IS but still faces some limitations. Therefore， choosing a measure that can assist in the treatment of IS is particularly important. A large number of studies have confirmed that traditional Chinese medicine can treat IS based on the effective ingredients and extracts of traditional Chinese medicine monomers and formulas，utilizing advantages such as multiple targets，multiple bioactive ingredients，multiple systems，and fewer adverse reactions to ensure the safety and effectiveness of the treatment pathway. At present，the mechanism of action of traditional Chinese medicine in treating IS can be achieved by intervening in various signaling pathways，mainly including secretory glycoprotein/β-catenin（Wnt/β-catenin） signaling pathway，phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway，nuclear factor kappa-B（NF-κB） signaling pathway，Toll-like receptor 4/NOD-like receptor protein 3（TLR4/NLRP3） signaling pathway，mitogen-activated protein kinase（MAPK） signaling pathway，and neurogenic site-gap homologous protein（Notch） signaling pathway. This article summarized the relationship between IS and related signaling pathways in recent years，as well as the regulation of IS-related pathways and corresponding mechanisms by traditional Chinese medicine，so as to provide a reference for future clinical and experimental research on IS.

Objective:To explore the predictors and reasons for restenosis in patients with Takayasu′s arteritis(TA) involved renal artery after plain old balloon angioplasty(POBA).Methods:The clinical data of 47 TA patients (47) with renal artery admitted to Xuanwu Hospital, Capital Medical University from January 2014 to December 2020 were analyzed, including 12 man and 35 female. The age ranged from 21 to 43 years old, with an average of (28.52±10.78) years old. All patient were diagnosed as TA and underwent POBA. The patients were divided into restenosis group ( n=18) and non-restenosis group ( n=29). The patients were followed up at 1, 3, and 6 months after surgery, and after 6 months, the patients were followed up every 6 months. All patients were followed up from 36 to 108 months.The basic clinical data of the two groups were compared, and the length of stent and residual stenosis were also compared. Measurement data were expressed as ( ± s), and t-test was used for comparison between groups. Counting data were expressed as the number of cases and percentage, and comparison between groups was analyzed using the chi-square test. Multivariate Logistic regression model was used to analyze the independent risk factors of restenosis after balloon dilation, and the OR value and 95% confidence interval were calculated. Logistic regression model was used to analyze the independent risk factors for restenosis after balloon dilation. Results:All patients received POBA and operation was successfully. Restenosis was found in 18 patients, and 29 patients remained normal during the follow-up. The primary patency rate was 61.7%. Multivariate Logistic regression analysis showed that HDL-C and lesion length were the influencing factors of restenosis after POBA in TA of renal artery. The serum HDL-C level was significantly lower and the lesion was significantly longer in restenosis group than in non-restenosis group ( P<0.05). The proportion of residual stenosis>20% was higher in restenosis group than in non-restenosis group ( P>0.05). Conclusion:Serum HDL-C level, lesion length may be may be independent influencing factors of restenosis after plain old balloon angioplasty in TA of the renal artery restenosis.

Objective:To investigate the clinical effect of composite surgery in the treatment of chronic common carotid artery occlusion(CCAO).Methods:A retrospective descriptive study was conducted. The clinical data of 7 patients with CCAO admitted to Xuanwu Hospital, Capital Medical University from October 2020 to December 2023 were collected retrospectively. There were 6 males and 1 female. The age was (66.7±10.9) years, ranging from 52 to 83 years. Outpatient or telephone follow-up were conducted after surgery, carotid artery ultrasound or computed tomography angiography were performed at 3 months, 6 months, and 1 year postoperatively to determine vascular patency. The selection of surgical methods and clinical effect were analyzed. Normally distributed measurement data were expressed as mean±standard deviation ( ± s). The measurement data of skewed distribution were expressed by M ( Q1, Q3). Count data were expressed as frequency. Results:All 7 patients were diagnosed with chronic CCAO before operation, 6 on the left and 1 on the right. 3 cases affected the middle and distal segments of the common carotid artery, 1 case affected the proximal segment, and 1 case each affected the middle and distal segments, the remaining case involves the entire common carotid artery. All the procedures were successfully performed, among which 4 cases underwent carotid endarterectomy combined with stent placement, and 3 cases did not receive stent placement after carotid endarterectomy. 1 patient developed neck hematoma after surgery and the remaining patients recovered well after surgery without any complications or deaths. The follow-up time was 13.5(4.0, 20.5) months; 1 patient was lost to follow-up, and 6 patients received effective follow-up. the common carotid artery remained unobstructed in all 6 patients, and there were no transient ischemic attacks or strokes during the follow-up period.Conclusion:Composite surgery is a safe and feasible method that can be used to treat chronic CCAO lesions, and has satisfactory short-term results.

Objective:To explore the long-term efficacy and safety of gene therapy with pUDK-hepatocyte growth factor (pUDK-HGF) for rest pain and ulcers caused by critical limb ischemia.Methods:Long-term follow-up were conducted through outpatient and telephone on patients who completed the pUDK-HGF Phase Ⅱ randomized double-blind placebo-controlled trial. The occurrence of tumors was observed, and tumor markers detection, fundus examination, visual analogue scale (VAS), and lower limb CT angiography (CTA) were performed according to voluntary principle. The results were analyzed descri-ptively and statistically.Results:A total of 53 patients were included in the analysis, of which 15 (28.3%) were in the placebo group and 38 (71.7%) were in the pUDK-HGF treatment group in the Phase Ⅱ clinical trial. The median follow-up time was 2.8 years, ranging from 1.7 to 3.5 years. During the follow-up period, no tumor was found in the 53 patients. Among the 38 patients in the pUDK-HGF treatment group, 18 underwent comprehensive examination and evaluation, including tumor markers, fundus and CTA examination, and patients with resting pain underwent VAS evaluation. Among them, 1 patient had transient mild elevation of carcinoembryonic antigen, and no abnormal tumor markers were found in the other 17 patients; no proliferative retinal vasculopathy was found in the fundus examination. At the end of the phase Ⅱ clinical trial (out-group), 3 were effective and 2 were ineffective of the 5 patients with rest pain; at the end of this follow-up period, 4 were evaluated as effectiveness and 1 as ineffectiveness according to CTA, and 5 were all evaluated as effectiveness according to VAS. Of the 13 patients with ulcer, 9 were evaluated as effectiveness and 4 were as ineffectiveness according to CTA at out-group; 10 were evaluated as effectiveness and 3 were as ineffectiveness at the end of this follow-up.Conclusions:pUDK-HGF had relatively good safety in the treatment of rest pain and ulcers caused by critical limb ischemia. No risk of carcinogenesis and proliferative retinal vasculopathy has been found, and the long-term efficacy of pUDK-HGF is good.
