Objective: To explore the association between mental health status and adverse childhood experiences (ACEs) among sexual minority college students, so as to provide a scientific basis for mental health education and health promotion in universities. Methods: From January to February 2024, convenience and cluster sampling methods were used to select 1 792 college students from 11 colleges in Guangxi. A self reporting method was applied to identify 476 sexual minority individuals. The Symptom Check-List 90 (SCL-90) and the Simplified Chinese Adverse Childhood Experiences International Questionnaire (SC-ACE-IQ) were employed to assess mental health and ACEs. Multivariate Logistic regression analysis was conducted to examine the associations. Results: The detection rates of all psychological issues among sexual minority college students in Guangxi were significantly higher than those of non sexual minority college students ( χ 2=56.01-91.39, all P <0.01). Except for physical neglect, bullying, and community violence, sexual minority students exhibited higher reporting rates of other ACEs types compared to nonsexual minority students ( χ 2= 4.52-13.34, all P <0.05). The total ACEs score for college students was 1.00 (1.00, 2.00), while the SCL-90 total score was 96.00 (113.00, 160.00). Spearman correlation analysis revealed a positive correlation between ACEs total scores and SCL-90 total scores ( r=0.29, P <0.05). Additionally, all ACEs subscales, including emotional neglect, physical neglect, emotional abuse, sexual abuse, parental loss, domestic violence, and community violence were positively correlated with corresponding SCL-90 subscale scores ( r =0.05-0.22, all P <0.05). Multivariate Logistic regression analysis showed that family violence increased the risk of mental health issues for sexual minority students ( OR=1.61, 95%CI =1.26-2.09); emotional neglect ( OR= 1.05 , 95%CI =1.00-1.10), physical neglect ( OR=1.20, 95%CI =1.06-1.35), sexual abuse ( OR=1.49, 95%CI =1.15-1.93) increased mental health risks for non sexual minority students (all P <0.05). The cumulative effects of ACEs were all statistically significant in the total sample and both subgroups (all P <0.05). Conclusion Mental health status among sexual minority college students in Guangxi is associated with ACEs, and their well being requires active attention

Objective: To explore the association between time to first cigarette (TTFC) and expiratory airflow limitation, so as to provide a reference for the prevention and control of pulmonary function decline. Methods: Based on the baseline survey of the China Multi-Ethnic Cohort (CMEC), the demographic, lifestyle behavior, smoking behavior, and TTFC data of permanent residents aged 30 to 79 years in Chengdu City were collected from 2018 to 2019. The TTFC was divided into ≤5, 6-30, 31-60, and >60 minutes. Expiratory airflow limitation was determined when the proportion of the measured peak expiratory flow to the predicted value was less than 80%. The association between TTFC and expiratory airflow limitation was analyzed using a multivariable logistic regression model, and subgroup analyses were conducted according to smoking cessation, age of starting smoking, smoking duration, average daily smoking volume, and the habit of deep inhalation into the lungs. Results: A total of 6 766 residents were investigated, among whom 6 402 were males, accounting for 94.62%. The median age was 52 (interquartile range, 19) years. A total of 2 468 residents were detected with expiratory airflow limitation, with a detection rate of 36.48%. Multivariable logistic regression analysis showed that after adjusting for demographics, lifestyle behavior, smoking cessation, age of starting smoking, smoking duration, average daily smoking volume, and the habit of deep inhalation into the lungs, TTFC ≤5 minutes (OR=1.203, 95%CI: 1.035-1.397) and 6-30 minutes (OR=1.174, 95%CI: 1.002-1.374) were associated with an increased risk of expiratory airflow limitation. Subgroup analyses showed that there was no interaction between smoking behavior and TTFC on the risk of expiratory airflow limitation (all P>0.05). Conclusion A shorter TTFC is associated with an increased risk of expiratory airflow limitation among residents aged 30 to 79 years, and the association is not affected by snoking behaviors such as smoking cessation, age of starting smoking, smoking duration and average daily smoking volume.

Objective To explore the effect of visual balance training combined with digital treadmill intervention on walking func-tion in patients with ischemic stroke.Methods From July,2023 to December,2024,90 patients with ischemic stroke in Gansu Provincial Hospital were ran-domly divided into control group(n=30),treadmill group(n=30)and combined group(n=30).All groups re-ceived routine rehabilitation treatment,while the treadmill group added digital treadmill training,and the com-bined group added visual feedback balance training and digital treadmill training,for four weeks.All groups were assessed with Berg Balance Scale(BBS),Pro-Kin visual feedback balance training system,Tinetti Performance-Oriented Mobility Assessment(POMA),digital treadmill system,Timed Up and Go Test(TUGT),Fugl-Meyer Assessment-Lower Extremities(FMA-LE),Functional Ambulation Category(FAC)and modified Barthel Index(MBI)before and after intervention.Results The effects of intra-group(F>147.291,P<0.001),inter-group(F>4.919,P<0.05)and interaction(F>18.386,P<0.001)were all significant for the indicators including BBS score,length trajectory and elliptical area of eyes open or closed,POMA score,step length,hip and knee range of motion on the healthy and affected side,TUGT time,FMA-LE score,and MBI score.Post-hoc tests showed that after treatment,all the above indicators improved in each group(P<0.01),and they were the best in the combined group,followed by the treadmill group(P<0.05).After treatment,the FAC grades improved in all the groups(|Z|>1.971,P<0.05),and it was better in the combined group than in the control group(P<0.01).Conclusion Visual feedback balance training combined with digital treadmill intervention can improve balance function,walking ability and activities of daily living in patients with ischemic stroke,which is more effective than tread-mill training alone.

Parkinson's disease is a neurodegenerative disease that mostly occurs in middle-aged and elderly people. It is characterized by progressive loss of dopaminergic neurons in the substantia nigra and aggregation of Lewy bodies, resulting in a series of motor symptoms and non-motor symptoms. Depression is the most important manifestation of non-motor symptoms, which seriously affects the quality of life of patients. Clinicians often use antidepressant drugs to improve the depressive symptoms of patients with Parkinson 's disease, but it is still urgent to solve the problems of drug side effects and drug resistance caused by such methods. Repetitive transcranial magnetic stimulation is a safe and non-invasive neuromodulation technique that can change the excitability of the corticospinal tract, induce the release of dopamine and other neurotransmitters, and further improve the depressive symptoms of patients with Parkinson 's disease. Based on this, this paper discusses and summarizes the research progress on the efficacy and potential mechanism of repetitive transcranial magnetic stimulation for improving depression in Parkinson 's disease at home and abroad, in order to provide reference for related clinical application research.

OBJECTIVE: The self-defined multidisciplinary (endocrinology, vascular surgery, and orthopedics) scoring system (EMO scoring system for short) was designed. The feasibility of the EMO scoring system to guide the proximal tibial transverse transport (TTT) for diabetic foot wounds was preliminarily explored. METHODS: Based on the current commonly used clinical criteria for diabetic foot judgment, expert consensus, guidelines, and related research progress in the treatment of diabetic foot wounds, combined with clinical experience, a set of EMO scoring systems including endocrinology, vascular surgery, and orthopedics was formulated. The criteria for selecting conservative treatment, TTT after baseline improvement, and TTT based on scoring results was proposed. A total of 56 patients with diabetic foot wounds who were admitted between September 2017 and July 2022 and met the selection criteria was taken as the study subjects. Among them, 28 patients were treated with TTT and 28 patients were treated conservatively. The patients were graded according to the EMO scoring system, the corresponding treatment methods were selected, and the actual treatment methods and results of the patients were compared. RESULTS: The EMO scoring system was formed through literature retrieval and clinical experiences. The system included three criteria, namely endocrinology (E), macrovascular disease (M), and orthopedics (O), which were divided into multiple subtypes according to the relevant evaluation items, and finally the diabetic foot wound was divided into 8 types, which correspondingly selected TTT, TTT after baseline improvement, and conservative treatment. All 56 patients were followed up 12 months after treatment. Among them, the wound healing rate of the TTT group was 85.71% (24/28), which was higher than that of the conservative treatment group [53.57% (15/28)]. At 12 week after treatment, CT angiography showed that there were more small blood vessels in the wound and ipsilateral limb in TTT group than in the conservative treatment group. Based on the EMO scoring system, 14 of the 56 patients needed conservative treatment, 29 patients needed TTT, and 13 patients needed TTT after baseline improvement. Compared with the clinical data of the patients, the wound healing rate of the patients judged to be TTT was 75.86% (22/29), of which 21 cases were actually treated with TTT, and the healing rate was 90.48%; 8 patients were treated conservatively, and the healing rate was 37.50%. The wound healing rate of the patients judged to be conservative treatment was 92.86% (13/14), of which 1 case was actually treated with TTT, and the healing rate was 100%; 13 cases were treated conservatively, and the healing rate was 92.31%; 1 case experienced minor amputation. The wound healing rate of the patients judged to TTT after baseline improvement was only 30.77% (4/13), of which 6 cases were actually treated with TTT, and the healing rate was 66.67%; 7 cases were treated conservatively, and the healing rate was 0. CONCLUSION EMO scoring system can comprehensively evaluate the diabetic foot wounds, and make personalized judgment on whether TTT treatment is feasible, so as to improve the level of diabetic foot wound treatment and the prognosis of patients.

Objective: To investigate the impact of RHAG 808A variant, commonly identified in the Chinese population, on RhAG protein, RhD and RhCE antigens expression through in vivo and in vitro expression analysis. Methods: A missense mutation of RHAG gene (c. 808G>A, p. Val270Ile) with high frequency was found in KMxD database. Bioinformatics analysis was performed using Polyphen-2 and Provean software. High resolution melting (HRM) method was utilized to screen for the variant carriers in the blood donors. The expression of RhAG protein, RhD and RhCE antigens on the surface of red cells of variant carriers were detected via flow cytometry. Wild-type and mutant vectors of RHAG were constructed and transfected into HEK 293T cells for in vitro expression analysis. Then, the expression of RhAG protein, RhD and RhCE antigens were analyzed by flow cytometry. Results: Polyphen-2 and Provean software suggested that the amino acid change (p. Val270Ile) of RhAG protein may be harmful or neutral respectively. Among the 999 blood donors from Guangzhou Blood Center, 4 homozygous carriers and 99 heterozygous carriers of RHAG 808A mutant allele were identified. The frequency of this allele was 5.4% (107/1 998). No significant differences in RhAG protein, RhD and RhCE antigens expression level was identified between the homozygous carriers, heterozygous carriers of RHAG 808A variant allele and the wild-type individuals. In vitro analysis for antigen expression study obtained the similar results. Conclusion: The RHAG 808A variant allele commonly identified in the Chinese population has no effect on the expression of RhAG protein, RhD and RhCE antigens, so the variant should be a population polymorphism site.

Objective: To investigate the prevalence and influencing factors of dyslipidemia among residents in Chengdu City, so as to provide insights into improving the prevention and control of dyslipidemia. Methods: Based on the baseline survey of the Natural Population Cohort Study in Southwest China, residents aged 30 to 79 years was selected from 34 towns (communities) in 5 counties (districts) of Chengdu City using the multi-stage stratified cluster random sampling method in 2018. Demographic information and lifestyle behaviors were collected through questionnaires. Blood pressure, fasting blood glucose, serum uric acid, total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were collected through physical examination and laboratory tests. A multivariable logistic regression model was used to identify the factors affecting dyslipidamia. Results: A total of 21 113 participants were surveyed, including 9 331 males (44.20%) and 11 782 females (55.80%), and had a mean age of (50.80±12.32) years. The prevalence rate of dyslipidemia was 35.64%, and the prevalence rates of high TG, low-HDL-C, high TC and high LDL-C were 17.25%, 11.88%, 10.11% and 7.35%, respectively. Multivariable logistic regression analysis identified gender (male, OR=1.584, 95%CI: 1.463-1.716), age (50 to 79 years old, OR：1.221-1.444, 95%CI: 1.079-1.632), residence (urban, OR=1.123, 95%CI: 1.052-1.198), marital status (not married, OR=1.246, 95%CI: 1.128-1.376), educational level (high school and above, OR=0.914, 95%CI: 0.849-0.983), current smoking (OR=1.220, 95%CI: 1.121-1.327), drinking (1 to 2 d/week, OR=1.525, 95%CI: 1.368-1.700; 3 to 5 d/week, OR=1.857, 95%CI: 1.575-2.191; almost every day, OR=1.512, 95%CI: 1.269-1.801), sedentary time in leisure time (>2 h/d, OR=1.123, 95%CI: 1.046-1.206), central obesity (OR=2.212, 95%CI: 1.986-2.265), hypertension (OR=1.489, 95%CI: 1.388-1.598), diabetes (OR=1.998, 95%CI: 1.833-2.157) and hyperuricemia (OR=2.012, 95%CI: 1.848-2.192) as factors affecting dyslipidemia. Conclusion The prevalence of dyslipidemia among residents in Chengdu City was mainly associated with smoking, drinking, sedentary time, central obesity, hypertension, diabetes and hyperuricemia.

Objective To provide valuable insights for improving China’s special drug approval system by conducting an in-depth analysis of the practices of the U.S. Food and Drug Administration （FDA） in granting Emergency Use Authorizations （EUAs） for drugs. Methods A retrospective analysis was conducted on the FDA’s EUA decision-making process for COVID-19 therapeutics between January 2020 and June 2023. Results During the COVID-19 pandemic, the FDA adopted a series of regulatory science approaches to facilitate rapid approval of COVID-19 therapeutic drugs. The FDA granted EUA for a total of 15 COVID-19 therapeutic drugs and 4 COVID-19 vaccines, including expanded indications for marketed drugs, EUA for investigational drugs, revocation of EUA, and marketing after EUA. The main mechods for the rapid approval of EUA drugs by the FDA included the use of existing clinical trial data, omission of animal efficacy testing, merging of phase 1 and phase 2 clinical trials, and the use of clinical outcomes as surrogate endpoints, among other regulatory science methods. Conclusion The practices of the FDA in Emergency Use Authorization (EUA) of drugs, particularly its incorporation of regulatory scientific methods into the EUA process and the establishment of proactive monitoring mechanisms for drugs granted EUA, are worthy of emulation by China. It is suggested that China consider the experience of the FDA in the EUA system for drugs to further optimize and improve its special approval system for drugs.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in healthcare facilities in major regions of China in 2023.Methods Clinical isolates collected from 73 hospitals across China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2023 Clinical & Laboratory Standards Institute (CLSI) breakpoints.Results A total of 445199 clinical isolates were collected in 2023,of which 29.0％ were gram-positive and 71.0％ were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species (excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi) (MRSA,MRSE and MRCNS) was 29.6％,81.9％ and 78.5％,respectively.Methicillin-resistant strains showed significantly higher resistance rates to most antimicrobial agents than methicillin-susceptible strains (MSSA,MSSE and MSCNS).Overall,92.9％ of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 91.4％ of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis had significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 93.1％ in the isolates from children and and 95.9％ in the isolates from adults.The resistance rate to carbapenems was lower than 15.0％ for most Enterobacterales species except for Klebsiella,22.5％ and 23.6％ of which were resistant to imipenem and meropenem,respectively .Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.6％ to 10.0％.The resistance rate to imipenem and meropenem was 21.9％ and 17.4％ for Pseudomonas aeruginosa,respectively,and 67.5％ and 68.1％ for Acinetobacter baumannii,respectively.Conclusions Increasing resistance to the commonly used antimicrobial agents is still observed in clinical bacterial isolates.However,the prevalence of important crabapenem-resistant organisms such as crabapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a slightly decreasing trend.This finding suggests that strengthening bacterial resistance surveillance and multidisciplinary linkage are important for preventing the occurrence and development of bacterial resistance.
