BackgroundNon-suicidal self-injury （NSSI） behavior has become a global public health concern affecting the physical and mental health of adolescents. The experiential avoidance model posits that childhood trauma contributes to NSSI behavior through the mediating pathway of emotional dysregulation. However， existing research has predominantly focused on isolated psychological or social factors， with limited attention to their interactive effects of emotional dysregulation and social anxiety， both of which fall within the psychosocial domain. ObjectiveTo examine the relationship between childhood trauma and NSSI among adolescents， and to analyze the mediating role of emotional dysregulation and the moderating role of social anxiety， so as to provide evidence for targeted interventions for NSSI behavior of adolescents. MethodsA total of 282 adolescent inpatients who consecutively admitted to the Department of Psychiatry of Guangdong Provincial People's Hospital from March to December 2025 and met the Diagnostic and Statistical Manual of Mental Disorders，fifth edition（DSM-5）criteria for NSSI were enrolled as study participants. Participants were assessed using the general information questionnaire， the Adolescent Self-Harm Questionnaire， the Childhood Trauma Questionnaire （CTQ）， the Difficulties in Emotion Regulation Scale （DERS）， and the Social Anxiety Scale for Adolescents （SAS-A）. Pearson correlation analysis was used to examine correlations among scale scores. model 4 and model 58 of the Process 4.1 were used to test the mediating effect of emotional dysregulation and the moderating effect of social anxiety， respectively. ResultsCTQ score was positively associated with score of the Adolescent Self-Injury Questionnaire （r=0.279， P<0.01）. Emotional dysregulation significantly partially mediated the relationship between childhood trauma and NSSI behavior， with a mediating effect of 0.112 （95% CI： 0.043–0.208）， accounting for 40.14% of the total effect. Social anxiety moderated the association between childhood trauma and emotional dysregulation，the effect value was 0.102 （95% CI： 0.008–0.196）， as well as the relationship between emotional dysregulation and NSSI behavior， the effect value was 0.130 （95% CI： 0.033–0.226）. ConclusionEmotional dysregulation may mediate the relationship between childhood trauma and NSSI behavior among hospitalized adolescents， while social anxiety moderates both the first and second paths of this mediating process. ［Funded by Guangdong Medical Science and Technology Research Fund Project （number， A2022538）］

Objective We aimed to investigate the feasibility and method of constructing a traditional Chinese medicine(TCM)curative effect prediction model based on the data of Kechuanting acupoint plastering therapy in the treatment of bronchial asthma(asthma).Methods Data from the Chronic Disease Management Research Platform of 303 patients with asthma who were treated with Kechuanting acupoint plastering therapy for 6 weeks in the Department of Acupuncture and Rehabilitation of Jiangsu Hospital of Traditional Chinese Medicine from June to August 2018 to 2021 were selected.We used Phyton 3.10 for statistical analysis.After data preprocessing,the influencing factors were used to build models by Logistic regression,support vector machine,K-means clustering algorithm,Bayes algorithm,random forest method and Light gradient boosting machine(LightGBM)respectively,with the improvement of asthma control test score(ACT),forced expiratory volume in one second(FEV1)and exhaled nitric oxide(FeNO)as the outcome indicators.Then,the models were compared and analyzed.Subsequently,the superior model was used to establish the efficacy prediction model and verify its stability to obtain the accuracy rate and eliminate the relatively important factors.Results The accuracy rate of the Kechuanting acupoint plastering therapy curative effect prediction model established by the LightGBM model was more than 70%.Five important factors were selected,including allergic history,tabacco and alcohol abuse,plastering duration,ACT before treatment,and FeNO before treatment.According to the classification analysis and the relationship between the important factors and the outcome indicators,Kechuanting acupoint plastering therapy significantly improved the ACT of patients with no history of allergy,no tabacco and alcohol abuse,and poor ACT:5-15 points(P<0.05).Furthermore,Kechuanting acupoint plastering therapy improved FeNO more significantly in patients with more than 3 years of treatment than those with no more than 3 years(P<0.05).However,Kechuanting acupoint plastering therapy only improved FeNO in a few patients with poor asthma control levels(P<0.05)and severe airway inflammation(FeNO>50×10-9)(P>0.05).Conclusion Acupoint plastering application has a significant effect on improving the control level of asthma,but its effect on improving airway inflammation is limited.It is feasible to use data from the chronic disease management research platform to construct the prediction model.After optimization and testing,the predictive model established based on the data of this study may provide an effective evaluation tool for targeted clinical treatment.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％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)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed 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 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To introduce and validate the Pediatric Nausea Assessment Tool (PeNAT) and the Baxter Retching Faces Scale (BARF) in the assessment of chemotherapy induced nausea in Chinese children with malignant neoplasms, and to explore the cut-off value for rescue antiemetic.Methods:A prospective descriptive study was conducted, 244 children in Sun Yat-sen University Cancer Center with malignant neoplasms who received chemotherapy were selected by convenience sampling from July to August 2021. PeNAT, BARF, Visual Analogue Scale (VAS) and the Faces Pain Scale-Revised(FPS-R) were used to assess the severity of nausea and pain before and after chemotherapy, before and 30-60 minutes after the use of rescue antiemetic or analgesic. After chemotherapy, the children also were asked the changes of nausea severity and whether antiemetic was needed.Results:A test-retest reliability was conducted on the patients with the same severity of nausea before and after chemotherapy, and the intraclass correlation coefficient of the PeNAT and BARF were 0.940 (both P<0.05). After chemotherapy, the PeNAT and BARF were 1.5(1.0, 2.0) and 2.0(0, 2.0) points, which were significantly higher than the 1.0(1.0, 1.0) and 0(0, 0) points before chemotherapy ( Z = - 9.19, - 9.09, both P<0.01). The PeNAT and BARF of 11 cases receiving antiemetic before medication were 4.0 (4.0, 6.0) and 3.0(2.0, 4.0) points, which were higher than the 0(0, 2.0) and 1.0(1.0, 2.0) points without antiemetic ( Z = - 4.03, - 3.86, both P<0.05). After chemotherapy, the correlation coefficients between PeNAT or BARF and VAS-nausea were r = 0.933, 0.957 (both P<0.01), and FPS-R were r = 0.192, 0.189 (both P<0.05). After using antiemetic, PeNAT and BARF were 2.0(2.0, 3.0) and 2.5(2.0, 4.0) points, which were significant different than the 3.0(3.0, 3.8) and 4.0(4.0, 8.0) points before using antiemetic ( Z = - 2.97, - 2.83, both P<0.05). According ROC curves and cut-off values, it was determined that PeNAT≥3 and BARF≥4 had clinical significance and require clinical intervention. Conclusions:PeNAT and BARF have excellent reliability and validity in the assessment of chemotherapy induced nausea in children with malignant neoplasms, they can effectively identify the requirement of rescue antiemetic, and evaluate the efficacy of antiemetic.

To study the complete genomic sequence, genomic characteristics, and genetic variation of the bovine papillomavirus 2 genotype (BPV-2) Aks-01 strain at the molecular level, genotyping of this strain from the skin samples of cows in southern Xinjiang (China) was first detected by the polymerase chain reaction with FAP59/FAP64 primers. Based on the complete genome of the BPV-2 reference strain, specific primers and sequencing primers were designed, and the complete genome of the Aks-01 strain amplified and sequenced. Sequence analyses showed that genotyping of the Aks-01 strain belonged to BPV-2. The Aks-01 strain had the structural characteristics of BPV-2. The 7944-bp full-length genomic sequence of the Aks-01 strain was compiled using DNAStar™. The sequence of the Aks-01 strain had 98% similarity to the reference strain from GenBank. The Aks-01 strain was most closely related to BPV-1 and BPV-13. BPV-2, BPV-1 and BPV-13 were grouped within the genus Deltapapillomavirus. The Aks-01 strain is the first BPV-2 strain reported in southern Xinjiang.
