Objective:To investigate the prevalence of sexual drug use in men who have sex with men (MSM) in Chengdu and analyze the relationship between depression and sexual drug use.Methods:A total of 1 277 MSM were recruited between November 2021 and May 2022. Questionnaire was used to collect information about their demographic characteristics, depression status and sexual drug use behavior. Univariate and multivariate logistic regression models were used to analyze the relationship between depression and sexual drug use.Results:In the 1 277 MSM, assessment identified 503 mild depression cases (39.4%), 196 moderate depression cases (15.3%) and 171 severe depression cases (13.4%) and 444 MSM (34.8%) reported sexual drug use in the past 6 months. Multivariate logistic regression models showed that compared with non-depression, mild depression (a OR=1.67,95% CI:1.24-2.23), moderate depression (a OR=1.50,95% CI: 1.02-2.19) and severe depression (a OR=1.56,95% CI:1.04-2.32) were positively associated with sexual drug use. Conclusions:The prevalence of depression and sexual drug use were high in MSM in Chengdu. There was a positive correlation between depression and sexual drug use. It is necessary to pay close attention to depression and sexual drug use and conduct targeted intervention in MSM.

Retrograde intrarenal surgery（RIRS）has become a first-line therapeutic option for upper urinary tract stones ≤2 cm. Although conventional ureteral access sheaths enable smooth ureteroscope insertion and reduce intrarenal pressure，but the stone-free rate（SFR）remains limited. Recently，a novel flexible and navigable suction ureteral access sheath（FANS）has improved the stone clearance efficiency，therapeutic effect，and safety of RIRS. The advent of FANS is progressively reshaping the role of RIRS within urological endoscopic surgery. This review aims to summarize the current research on FANS in the management of urolithiasis and discuss potential directions for its future development.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To evaluate the relationship between perioperative myocardial injury(PMI)and serum N/OFQ levels in elderly patients with coronary heart disease.Methods Totally 120 elderly patients who underwent hip fracture surgery under general anesthesia from January 2022 to May 2023 were included,including 60 patients with coronary heart disease(CHD group)and 60 patients without coronary heart disease(control group).The venous blood of patients was collected 10 minutes before anesthesia induction(T0),12 hours after surgery(T1)and 24 hours after surgery(T2)to detect the content of N/OFQ and high-sensitivity myocardial troponin I(hs-cTnI)in serum.Record perioperative adverse cardiovascular events(PACE)and the use of vasoactive drugs during surgery.Results Compared with the control group,the N/OFQ and hs cTnI levels at T0 and T1 in the CHD group were significantly increased(P<0.05).There was a positive correlation between N/OFQ and hs-cTnI levels at T1 and T2 in CHD and control group(P<0.05).The use of PACE and intraoperative vasoactive drugs in the CHD group was higher than that in the control group(P<0.05).Conclusion There is a correlation between the increased N/OFQ content and PMI in elderly patients with coronary heart disease after surgery,which may become an early predictive indicator of PMI.

ObjectiveTo evaluate the effectiveness and safety of Qiaoqi Formula （翘芪组方） for mild influenza. MethodsA randomized controlled study was designed， recruiting 74 patients with mild influenza， who were randomly divided into trial group and control group. The trial group took Qiaoqi Formula orally， 40ml each time， twice a day； the control group took Lianhua Qingwen Capsules （连花清瘟胶囊） orally， 1.4 g each time， three times a day. Both groups were treated for 3 consecutive days and follow-up for 4 consecutive days after treatment. The time for fever reduction including onset of fever reduction， complete fever reduction time， fever reduction rates at 24， 48 and 72 hours， improvement of influenza symptoms， total traditional Chinese medicine （TCM） symptom score， and safety indicators in two groups after treatment were recorded. ResultsSixty-five patients were ultimately included， including 36 in the trial group and 29 in the control group. Onset time of fever reduction in the trial group was （15.49±23.47） h， the complete fever reduction time （21.37±30.06）h， and the 24 h， 48 h， 72 h， fever reduction rate was 77.14%， 88.57%， 91.42% respectively. The above indicators of the control group showed as （17.58±20.38）h， （24.30±21.87）h， 61.29%， 90.32%， 96.77% respectively， with no statistically significant differences （P＞0.05）. On the 7th day after treatment， the total score of TCM syndromes in trial group and control group decreased compared to those before treatment （P＜0.05）. There was no statistically significant difference in the cure rate， significant effective rate， effective rate， and total effective rate of TCM syndromes between groups （P＞0.05）. On the 4th day， the lymphocyte ratio of patients in the control group was higher than before treatment， while alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， urea， and creatinine of both groups before and after treatment were within the normal range. The main adverse reactions in both groups were mild headache and dizziness， and no serious adverse reactions observed. ConclusionThe therapeutic effect of Qiaoqi Formula in treating mild influenza is equivalent to Lianhua Qingwen Capsules， which can shorten the fever reduction time， improve clinical symptoms， and no adverse events observed during the study.

Objective:To explore the cognition and behavior of nurses in blood purification centers on the quality of death of patients undergoing maintenance hemodialysis.Methods:The descriptive phenomenological research method was adopted. From August to October 2022, a total of 14 nurses from blood purification centers in three hospitals, namely Beijing Union Medical College Hospital, Beijing Hospital and Beijing Chaoyang Hospital were selected as interview subjects by the purposive sampling method. Semi-structured in-depth interview method was used to collect data, and Colaizzi 7-step analysis method was used to analyze data.Results:The cognition and behavior of nurses in the blood purification center towards the quality of death of maintenance hemodialysis patients were analyzed into four themes, namely factors affecting the quality of death of patients, convenient conditions for nurses to carry out quality of death improvement work, proactive measures taken by nurses to improve the quality of death and obstacles in the process of improving the quality of death of patients.Conclusions:The nurses in the blood purification centers have special characteristics in their feelings about the death of patients with maintenance hemodialysis, and they have certain cognition and judgment about the quality of death of patients. Managers need to pay attention to the relevant needs and suggestions of the nurses in the blood purification centers and provide help and guidance, so as to continuously improve the quality of patient death and achieve the goal of optimal death of patients.
