Objective:To understanding the epidemiological characteristics of self-injury/suicide among residents in Jiangsu Province, as well as grasping the current situation and patterns, will provide support and a basis for reducing the occurrence of self-injury/suicide harm.Methods:Data on self-injury/suicide cases from 2006 to 2022 were collected from 12 national injury surveillance sentinel hospitals in Jiangsu Province. The prevalence characteristics were analyzed using R 4.2.1 software, employing the chi-square test and Post Hoc testing for pairwise comparisons between groups, with adjusted standardized residuals to assess group differences.Results:From 2006 to 2022, there were 5 504 cases of self-injury/suicide monitored in Jiangsu Province, comprising 2 016 males and 3 488 females, resulting in a male-to-female ratio of 1∶1.73. The top three months for self-injury/suicide incidents were June (10.12%), May (9.85%), and July (9.25%). The peak times for these incidents were between 00:00-01:00 and 20:00-21:00. The majority of self-harm/suicide incidents occurred at home (73.64%). The primary methods of self-harm/suicide were poisoning and injuries caused by sharp objects, accounting for 47.11% and 35.32%, respectively. The frequently injured body parts were the upper limbs (34.97%) and generalized injuries throughout the body (25.56%). In terms of severity, mild cases predominated (49.78%). Further analysis reveals that, compared to male, self-harm/suicidal characteristics, female self-harm/suicidal behavior is more likely to occur at home, with poisoning as the predominant method, injuries affecting multiple body areas, and the severity of injuries being relatively mild ( P<0.001). In the 15-29 age group, self-harm/suicidal injuries predominantly affect the upper limbs ( P<0.001). Self-harm/suicidal behavior is more likely to occur at home, with poisoning being the primary method, injuries affecting multiple body areas, and the severity of injuries being more severe (all P<0.001) for individuals aged 60 and above. Conclusions:To prevent and control self-harm/suicidal behavior and reduce the suicide mortality rate, it is essential to strengthen support and care for key populations such as women, those aged 15 to 29, and individuals aged 60 and above. Monitoring and management should be enhanced in key locations where self-harm/suicide is more likely to occur, such as homes, public living spaces, schools, and public areas, to enable early detection. Controlling potential methods of suicide is crucial, such as continuing to strengthen regulations and restrictions on highly toxic pesticides and reducing the likelihood of fatal overdoses from medications.

Objective To understand the current situation of healthcare-associated infection(HAI)in China,pro-vide data support and decision-making basis for formulating scientific and effective strategies for HAI prevention and control.Methods A nationwide cross-sectional survey on HAI was conducted among various types and levels of medical institutions in China according to a unified protocol of bedside surveys and case investigations.Results In 2024,a total of 5 736 medical institutions and 2 751 765 patients were surveyed.Among them,34 889 HAI cases were identified,with a prevalence rate of 1.27％.The number of HAI episodes was 38 032,and case prevalence rate was 1.38％.The prevalence rate of HAI in medical institutions in different regions of China ranged from 0.66％to 2.35％.Among medical institutions of different scales,those with a bed capacity of ≥900 had the high-est incidence of HAI,reaching 1.65％.The most common infection site was the lower respiratory tract(44.66％),followed by the urinary tract(12.94％),surgical site(9.32％),upper respiratory tract(7.02％),and bloodstream infection(5.78％).The top 3 departments with the highest HAI rates were the general intensive care unit(10.02％),department of neurosurgery(5.51％),and department(group)of hematology(5.34％).A total of 23 238 strains of HAI pathogens were detected,with 10 714 strains(46.10％)from lower respiratory tract speci-mens.The top 5 detected strains were Klebsiella pneumoniae(14.76％),Pseudomonas aeruginosa(13.33％),Escherichia coli(12.79％),Acinetobacter baumannii(9.23％),and Staphylococcus aureus(7.88％).231 944 pa-tients underwent class Ⅰ incision surgery were monitored,with 1 647 cases experienced surgical site infection,and the prevalence rate of surgical site infection was 0.71％.The number of patients who should undergo pathogen de-tection(patients receiving therapeutic and therapeutic combined prophylactic antimicrobial agents)was 715 179,while the actual number was 480 492,with a pathogen detection rate of 67.18％.425 225 patients received patho-genic detection before treatment,with a detection rate of 59.46％.Conclusion The overall HAI prevalence in Chi-na is lower,showing disparities among medical institutions of different regions and scales.Therefore,precise imple-mentation of measures is necessary for HAI prevention and control,with a focus on high-risk institutions and high-risk departments,key areas,and critical procedures.All levels of medical institutions should continuously reduce the incidence of HAI by strengthening monitoring,standardizing the use of antimicrobial agents,and reinforcing basic HAI prevention and control measures.

Objective:To analyze the comorbidity status and influencing factors of hypertension, diabetes, and dyslipidemia among middle-aged and elderly in Jiangsu Province and to provide support for "co-management of the three diseases".Methods:Data originated from the Comprehensive Prevention and Control Project of Cardiovascular and Cerebrovascular Diseases baseline survey in Jiangsu Province. Questionnaire interviews, physical examinations, and laboratory tests were conducted on 136 433 permanent residents aged ≥35 years who participated in the survey from 2021 to 2023. A multinomial logit model was established using SPSS 23.0 to analyze the influencing factors of the three comorbidities.Results:The comorbidity rate of hypertension, diabetes, and dyslipidemia among middle-aged and older adults in Jiangsu Province was 7.3%. Hypertension combined with dyslipidemia was the main comorbidity pattern, and patients with diabetes accounted for the largest proportion. Multinomial logistic regression analysis showed that the risk of being two types of the three comorbidities was higher in male, aging, urban residents, and those with high/technical secondary school, higher frequency of cigarette smoking and alcohol drinking, and longer daily sedentary time; the risk was lower in those with higher the level of physical activity and longer daily sleep time. Among the three types of comorbidities, males with aging, high/technical secondary school, regular smoking/quitting, higher frequency of alcohol drinking, and longer daily sedentary time had higher risk; those with an annual family income of 30 000-99 999 RMB, higher level of physical activity, and the daily sleep time of 7 hours had the lower risk (all P<0.05). Conclusions:The prevention and control of the three comorbidities among middle-aged and older adults in Jiangsu Province still needs strengthening. High-risk groups for the three diseases and comorbidities, such as males, low-income , and high/technical secondary school should be focused on. Middle-aged and older adults are suggested to increase daily physical activity, reduce daily static time, reasonably arrange sleep duration, and quit smoking and drinking as early as possible to maintain a healthy weight.

Recent clinical studies have shown that mutation of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) gene in cancer cells may be associated with immunosuppressive tumor microenvironment (TME) and poor response to immune checkpoint blockade (ICB) therapy. Therefore, efficiently restoring PTEN gene expression in cancer cells is critical to improving the responding rate to ICB therapy. Here, we screened an adeno-associated virus (AAV) capsid for efficient PTEN gene delivery into B16F10 tumor cells. We demonstrated that intratumorally injected AAV6-PTEN successfully restored the tumor cell PTEN gene expression and effectively inhibited tumor progression by inducing tumor cell immunogenic cell death (ICD) and increasing immune cell infiltration. Moreover, we developed an anti-PD-1 loaded phospholipid-based phase separation gel (PPSG), which formed an in situ depot and sustainably release anti-PD-1 drugs within 42 days in vivo. In order to effectively inhibit the recurrence of melanoma, we further applied a triple therapy based on AAV6-PTEN, PPSG^@anti-PD-1 and CpG, and showed that this triple therapy strategy enhanced the synergistic antitumor immune effect and also induced robust immune memory, which completely rejected tumor recurrence. We anticipate that this triple therapy could be used as a new tumor combination therapy with stronger immune activation capacity and tumor inhibition efficacy.

OBJECTIVE To establish the fingerprints of Tianma jiannao granules （TJG） and the method for content determination to evaluate the quality of TJG comprehensively combined with chemometric analysis. METHODS High-performance liquid chromatography （HPLC） was used to establish the fingerprints of 13 batches （S1-S3） of TJG and determine the contents of inosine， gastrodin， parishin B and parishin E. Cluster analysis， principal component analysis， and orthogonal partial least squares- discriminant analysis were performed using SPSS 20.0 and SIMCA 18 software； using variable importance projection （VIP） value greater than 1 as a criterion， marker components that affected quality were screened. RESULTS A total of 28 common peaks were identified in the 13 batches of TJG with similarities greater than 0.9， and 7 common peaks were identified， which were gastrodin， p-hydroxybenzyl alcohol， parishin B， parishin E， rhynchophylline， inosine and salidroside. The 13 batches of TJG were clustered into 3 categories， S1-S2， S8-S10 and S12 were clustered into one category； S3 and S7 were clustered into one category； S4-S6， S11 and S13 were clustered into one category. VIP of inosine was greater than 1. The contents of inosine， gastrodin， parishin B and parishin E were 62.637-176.677， 17.821-37.642， 5.748-16.077 and 5.660-13.510 μg/g. CONCLUSIONS The established HPLC fingerprints and content determination method are stable， reliable and highly reproducible， which can be used to evaluate the quality of TJG in combination with chemometric analysis. Inosine may be a marker component that affects the quality of TJG. There are differences in the quality of 13 batches of TJG.

Due to the insufficient long-term protection and significant efficacy reduction to new variants of current COVID-19 vaccines, the epidemic prevention and control are still challenging. Here, we employ a capsid and antigen structure engineering (CASE) strategy to manufacture an adeno-associated viral serotype 6-based vaccine (S663V-RBD), which expresses trimeric receptor binding domain (RBD) of spike protein fused with a biological adjuvant RS09. Impressively, the engineered S663V-RBD could rapidly induce a satisfactory RBD-specific IgG titer within 2 weeks and maintain the titer for more than 4 months. Compared to the licensed BBIBP-CorV (Sinopharm, China), a single-dose S663V-RBD induced more endurable and robust immune responses in mice and elicited superior neutralizing antibodies against three typical SARS-CoV-2 pseudoviruses including wild type, C.37 (Lambda) and B.1.617.2 (Delta). More interestingly, the intramuscular injection of S663V-RBD could overcome pre-existing immunity against the capsid. Given its effectiveness, the CASE-based S663V-RBD may provide a new solution for the current and next pandemic.

【Objective】 To explore the intention of voluntary blood donation in students from a middle vocational school in Jinhua and its influencing factors. 【Methods】 A total of 400 students were enrolled from a middle vocational school in Jinhua by convenience sampling, and a self-designed questionnaire was issued to each student to investigate the cognition, intention and attitude of voluntary blood donation. The influencing factors of voluntary blood donation intention were analyzed by Logistic regression. 【Results】 A total of 394 valid questionnaires(98.50%) were collected. For 394 surveyed students, the average score of cognition of voluntary blood donation was (7.27±2.69) points, and the overall rate of intention to voluntary blood donation was 21.32%. Logistic regression analysis equation consisted of family support, better cognition, feeling happy about blood donation and worrying about blood donation, with risk ratios(OR) as 31.78, 188.69, 26.27 and 0.01, respectively(all P<0.05). 【Conclusion】 Students from a middle vocational school showed poor congnition and intention of voluntary blood donation.Family support for voluntary blood donation, better cognition of voluntary blood donation and happiness for blood donation were positive factors, and the fear of blood donation was a negative factor.It is necessary to strengthen the publicity of blood donation among students in middle vocational school to improve their congnition and intention to voluntary blood donation.

Objective:To explore the relationship between sleep quality and depression among fertile women, and provide a scientific reference for protecting the mental health of fertile women.Methods:The study included 12 518 fertile women who were 15 to 49 years old from the Second Affiliated Hospital of Kunming Medical University and Maternal and Child Health Hospital of Qujing in Yunnan Province from January 2019 to November 2019. Sleep quality was collected by using self-reported questionnaires, and depression was evaluated by using the Edinburgh Postpartum Depression Scale. We used logistic regression to analyze the relationship between sleep quality and depression after controlling for other factors.Results:Among 12 518 fertile women, 3197 had poor sleep quality which accounted for 25.54% (95% CI=24.77%-26.30%). The detection rate of depression was 55.59% (6959/12 518; 95% CI=54.72%-56.46%). The detection rate of depression of the poor sleep quality group [75.40% (2410/3197)] was significantly higher than that of the good sleep quality group [48.80% (4549/9321), P<0.001]. Multivariate logistic regression analysis showed that after controlling for basic demographic characteristics, health status, lifestyle habits and other factors, depression was still associated with poor sleep quality (a OR=3.28, 95% CI=2.99-3.60; P<0.001). Conclusion:The problem of depression and sleep quality on fertile women cannot be ignored, and sleep quality was associated with depression significantly which suggested that it was necessary to keep good life style, improve sleep quality and promote mental health.
