BackgroundNon-suicidal self-injury （NSSI） behavior among adolescents has become a global public health concern. Anxiety and depression are considered key factors influencing NSSI behavior， while social support may play a protective role in alleviating emotional and behavioral issues. However， existing research has primarily focused on the direct impact of individual factors on NSSI behavior， with insufficient exploration of the combined effects of anxiety， depression and social support. ObjectiveTo investigate the direct effect of anxiety on NSSI， the mediating role of depression and the moderating role of social support in relationship between anxiety and NSSI behavior， thus to provide references for the prevention and intervention of NSSI behavior among adolescents. MethodsIn February 2022， a total of 40 820 students in grades 7 to 12 across 10 middle schools in a district of Chengdu were selected as participants， and they were assessed using Generalized Anxiety Disorder Scale-7 item （GAD-7）， Patient's Health Questionnaire Depression Scale-9 item （PHQ-9）， Social Support Scale for Urban Students （SSSUS） and Adolescent Self-Harm Scale （ASHS）. Pearson correlation analysis was conducted to examine the correlations between scale scores among adolescents with NSSI behaviors. Mediation and moderation analyses were performed using Process 3.5 in SPSS， and the significance was tested with bootstrapping. The interaction was visualized by using simple slope analysis. ResultsAmong 34 534 （84.60%） valid respondents， 542 adolescents （1.57%） reported engaging in NSSI behavior. Significant differences in gender， GAD-7 scores， PHQ-9 scores， and SSSUS scores were observed between NSSI behavior group and non-NSSI group （χ²/t=62.889， 71.120， 94.365， -41.464， P<0.01）.Adolesents with NSSI showed positive correlations between GAD-7 scores and both ASHS and PHQ-9 scores （r=0.158， 0.166， P<0.01）. PHQ-9 scores were positively correlated with ASHS scores （r=0.364， P<0.01）， but negatively correlated with SSSUS scores （r=-0.290， P<0.01）. SSSUS scores were negatively correlated with ASHS scores （r=-0.247， P<0.01）. Depression partially mediated the relationship between anxiety and NSSI behavior， with an effect size of 0.544 （95% CI： 0.162~0.944）， accounting for 35.79% of the total effect. Social support moderated the relationship between depression and NSSI bahavior， with an effect value of -0.082 （95% CI： -0.135~-0.029）. ConclusionAnxiety not only directly influences NSSI bahavior among adolescents， also indirectly exacerbates it through depression， while social support mitigates the impact of depression on NSSI behavior. ［Funded by Youth Project of National Natural Science Foundation of China （number， 82401812）； Project of Health Commission of Sichuan Province （number， 24LCYJPT18）］

Objective: To analyze the disease burden and trends of oral diseases among China’s elderly population (1990-2021) and provide evidence for developing targeted intervention strategies Methods : Using data from the Global Burden of Disease (GBD) 2021 study, we extracted prevalence, incidence, and disability-adjusted life years (DALYs) for oral conditions (permanent dental caries, edentulism, periodontal diseases, and other oral disorders) in individuals aged ≥60 years in China. Due to data limitations, other oral diseases only included DALYs and prevalence. Age-standardized rates (ASR)—including age-standardized prevalence rate (ASPR), age-standardized incidence rate (ASIR), and age-standardized DALYs rate (ASDR)--were calculated. Trends were assessed via Joinpoint regression using average annual percentage change (AAPC), stratified by sex and age groups (60-64, 65-69, 70-74, 75-79, 80-84, 85-89, 90-94, 95+ years). Results: From 1990 to 2021, China’s elderly population exhibited distinct trends in oral disease burden. Overall oral diseases showed declining ASDR and ASPR, yet ASIR slightly increased. Permanent dental caries demonstrated significant rises across ASDR, ASIR, and ASPR. Edentulism showed declining ASDR and ASPR alongside stable ASIR. 95+ age group saw rising rates. Periodontal diseases remained largely stable in ASDR and ASPR but experienced a slight ASIR decline. Other oral disorders showed mild ASDR decline and stable ASPR. Notably, sex and age disparities persisted. Women consistently bore higher burdens for overall oral diseases, caries, edentulism, and other oral diseases but lower periodontal disease rates compared to men. 85-89, 90-95, 95+ age group faced rising DALYs and prevalence for overall oral diseases, while all other age groups demonstrated declining trends in both DALYs and prevalence; for permanent caries, the 60-64 age group showed the largest increases in DALY rate, incidence, and prevalence; edentulism demonstrated the most pronounced and sustained rises in DALY rate and prevalence in the 95+ group, while declining most rapidly in the 60-64 age group; for periodontal disease, both DALY rates and prevalence declined in the 90-94 and 95+ age groups, but increased across all measures (DALY rate, incidence, and prevalence) in the 70-74 and 75-79 age group; other oral conditions exhibited relatively stable burden distributions or minor changes, with no significant age-specific shifting trends observed. Conclusion From 1990 to 2021, China’s elderly oral disease burden declined overall, but caries surged, edentulism improved, periodontal diseases stabilized, and other oral diseases slightly declined. Prioritizing older women and the adults aged 85+ is critical to addressing evolving oral health needs.

Objective:To study the overall training effect of segmented training model on key fiberoptic bronchoscopy techniques for anesthesiology residents and the influence of key technique training order on the training effect.Methods:Different fiberoptic bronchoscopy simulators were used for specialized training in different key techniques of fiberoptic operation. To examine the effect of key technique learning order on the teaching effect, 40 anesthesiology residents who participated in fiberscope simulation training at Ruijin Hospital, Shanghai Jiaotong University School of Medicine between November 2022 and March 2023 were selected for this study. They were randomly divided into two groups (Group S and Group M) using a numerical table method. The teaching was completed using two orders of key techniques. The operation time, operation quality score, and theoretical knowledge mastery score of the two groups were recorded to compare the effect of key technique learning order on the mastery of fiberoptic skills. SPSS 29.0 statistical software was used for data analysis. Measurement data that conformed to normal distribution were expressed as mean ± standard deviation, and the independent samples t-test or Fisher's exact test were used for comparison between groups. The chi-square test was used for comparison of enumeration data. Results:After segmented training in each key technique, both groups of trainees were able to shorten the operation time of the corresponding key technique [SM simulator operation time (132.25±14.69) s vs. (49.80±4.46) s in group S, P<0.01; M simulator operation time (82.30±11.60) s vs. (57.10±6.77) s in group S, P<0.01; SM simulator operation time (83.10±10.62) s vs. (52.10±5.20) s in group M, P<0.01; M simulator operation time (132.25±14.69) s vs. (55.40±5.91) s in group M, P<0.01)]. Moreover, both groups showed a reduced number of wall touches [SM simulator wall touches (3.35±0.93) times vs. (0.65±0.49) times in group S, P<0.01; M simulator wall touches (2.50±1.05) times vs. (0.70±0.80) times in group S, P<0.01; SM simulator wall touches (1.55±1.15) times vs. (0.40±0.50) times in group M, P<0.01; M simulator wall touches (5.90±1.29) times vs. (1.10±0.79) times in group M, P<0.01]. There were no significant differences between the two groups in the performance score of fiberoptic-guided tracheal intubation after training [(92.50±5.97) points vs. (91.75±5.45) points] and in the lung segment localization time [(23.15±4.39) s, (21.40±4.84) s, (22.85±4.42) s vs. (22.75±5.11) s, (21.00±5.40) s, (21.50±5.10) s]. Conclusions:Segmented training on key fiberoptic bronchoscopy techniques is an effective model of fiberscope training for anesthesiology residents, and the order of training key techniques does not affect the effectiveness of training.

Aim To investigate the changes in the proliferation and apoptosis of Siha cells after knocking down Rho GTPase-activating protein 30(ARHGAP30).Methods After designing specific shARHGAP30 primers and connecting them to the pLKO.1 vector,we transformed them into Escherichia coli competent cells,then co-transfecting them with lentiviral helper plasmids into HEK-293T cells.We collected and filtered cell supernatant to obtain the vi-rus to infect Siha cells.RT-qPCR and Western blot were used to detect knockdown efficiency,as well as changes in the expression of Bax and Bcl-2 after trans-fection.The CCK-8 method was employed to measure the proliferation level of cells after knockdown.Results After successful construction of a lentiviral plasmid with knockdown of the ARHGAP30 gene and establish-ment of stably transfected Siha cells,ARHGAP30 tran-scription and translation(P＜0.01)in Siha cells de-creased,Bax/Bcl-2 significantly decreased(P＜0.01),indicating decreased apoptosis and increased cell proliferation(P＜0.01).Conclusions This study suggests the involvement of ARHGAP30 in the proliferation and apoptosis of Siha cells,and regulating the ARHGAP30 gene may interfere with the occurrence and development of cervical cancer.

Aim To investigate the protective poten-tial of paeoniflorin 6-oxy-benzenesulfonate(CP-25)in preserving knee cartilage integrity in osteoarthritis mice through inhibition of GRK2 activity.Methods The posttraumatic osteoarthritis model was established fol-lowing DMM surgery.The experiment consisted of a sham operation group,a model group,a CP-25 admin-istration group,and a paroxetine positive control group.Intragastric administration commenced after the surgery.After 12 weeks of administration,the animals were euthanized.Micro-CT imaging was used to ob-serve the knee cartilage degeneration and abnormal bone remodeling,and the joint histopathology of mice was observed by staining with ferrubens solid green.Immunohistochemistry and immunofluorescence were used to detect the expression level of related molecules in cartilage tissue.Furthermore,Western blot was em-ployed to determine GRK2 and EP4 membrane protein expression levels as well as total protein levels of GRK2 and MMP13 following CP-25 treatment.Results Compared with the sham operation group,the articular cartilage in the model group was significantly degrad-ed,with the cartilage surface calcifying and osteo-phytes forming.CP-25 could significantly reduce the number of osteophytes and the thickness of the sub-chondral plate of articular cartilage,promote the regen-eration of the cartilage matrix,reduce the expression of cartilage matrix degradation protein,and have a signifi-cant protective effect on knee cartilage.Immunohisto-chemical and immunofluorescence results showed that compared with the model group,CP-25 treatment sig-nificantly decreased the expressions of GRK2,AD-AMTS5 and MMP13 in knee tissue and increased the expressions of Col Ⅱ and Aggrecan in knee tissue.The results of in vitro experiments showed that CP-25 ad-ministration could significantly reduce the expression levels of GRK2 membrane protein and total protein,in-crease the level of EP4 membrane protein,and de-crease the level of MMP13.Conclusions The ad-ministration of CP-25 can significantly promote the re-generation of articular cartilage matrix in OA mice,re-duce the degradation of cartilage matrix,and exhibit therapeutic effects on OA.The mechanism behind this is related to the inhibition of GRK2-mediated cartilage matrix metabolism.

Aim To investigate the mechanisms of Chaijin JieYu Anshen formula modulating the depres-sive behaviors and the synaptic plasticity of hippocam-pal neurons in insomnia-concomitant depression rats based on the histone deacetylase 5(HDAC5)/myocyte enhancer factor 2C(MEF2C)pathway.Methods A rat model of insomnia-concomitant depression was es-tablished by PCPA injection combined with chronic un-predictable mild stress(CUMS),and the experiment was divided into the control group,the model group,the high,medium and low dose group of Chaijin JieYu Anshen formula,and the positive drug group.The de-pression of rats was evaluated by sugar-water prefer-ence test,open field test and morris water maze.The levels of 5-hydroxytryptamine(5-HT)and dopamine(DA)in serum were measured by enzyme linked im-munosorbent assay(ELISA).The pathological damage of hippocampal neurons was observed by HE staining and Nissl staining.The damage of dendritic spines of hippocampal neurons was observed by Golgi staining,and the levels of HDAC5,MEF2C,postsynaptic densi-ty-95(PSD-95)and synaptophysin 1(SYN1)in hip-pocampus were measured by Western blot,immunohis-tochemistry and immunofluorescence.Results Com-pared with the model group,the Chaijin JieYu Anshen formula could increase the sugar-water preference rate of the model rats,reduce the immobility time in the open field experiment,increase the total activity dis-tance,shorten the evasion latency in the localization navigation experiment,and prolong the residence time in the quadrant where the platform was located in the space exploration experiment(P＜0.05,P＜0.01).Moreover,the Chaijin JieYu Anshen formula improved the hippocampal neuron and dendritic spine damage and increase the dendritic branch length and dendritic spine density of hippocampal neurons(P＜0.01,P＜0.01),restore the serum levels of 5-HT and DA in insomnia-concomitant depression rats(P＜0.05,P＜0.01),down-regulate the HDAC5 protein,and up-regulate the expression of MEF2C,PSD-95,and SYN1 protein(P＜0.05,P＜0.01 or P＜0.001).Conclusions Chaijin JieYu Anshen formula may alle-viate the depression-like behavior of model rats by re-ducing the expression of HDAC5 protein,thus deregu-lating the inhibition of transcription factor MEF2C,promoting the expression of PSD-95 and SNY1 protein,and exerting a protective effect on hippocampal neurons and synapses.

Aim To investigate the effects of the phos-phodiesterase 8(PDE8)inhibitor PF-04957325 on learning and memory,anxiety and depression in Alzhe-imer's disease(AD)mice induced by Okadaic acid(OA),and to explore its mechanism.Methods Twenty-one 2-month-old male C57BL/6J mice were se-lected for the experiment and randomly divided into the control group,AD model group,and PDE8 inhibitor group(0.1 mg·kg-1).AD model was induced by bi-lateral hippocampal localization injection of OA(50 ng on each side)in the model and PDE8 inhibitor groups of mice.Two days after the injection of OA,PDE8 in-hibitor group was given 0.1 mg·kg-1 drug,while the AD model groups and control group were given with the same volume of vehicle for 21 consecutive days.On day 13 of inhibitor administration,behavioral tests re-lated to learning and memory abilities,anxiety and de-pressive behaviors were performed in mice.HE stai-ning was used to observe the morphology of neuronal cells in the DG,CA1,and CA3 regions of the hippo-campus of mice,and Western blot was used to detect the levels of phosphorylated Tau proteins at different sites within the hippocampus of mice as well as the ex-pression of proteins related to the PDE8/cAMP/CREB pathway.Results Compared with the control group,the Y-maze Spontaneous alternation,Recognition index of NOR and Latency of PAT were significantly shorter(P＜0.01),and Entries times、Time in the target quadrant of MWM were reduced(P＜0.05)in the AD model group,which showed a decrease in the ability of learning and memory,whereas the administration of PF-04957325 significantly improved the ability of learning and memory in the AD mice;mice in the AD model group showed a significant decrease in the num-ber of entries into the central area of the OFT and the time spent in the central area(P＜0.05),and a sig-nificant increase in the Immobility time of TST(P＜0.01),suggesting that the mice had anxiety and de-pression,and the administration of PF-04957325 did not improve the anxious behavior of the mice,but im-proved the depressed behavior to a certain extent;the hippocampus of the AD model group mice showed ker-nel solidification in the DG,CA1 and CA3 regions,and neurons were not neatly arranged,and the admin-istration of PF-04957325 could alleviate the damage of hippocampal nerve cells in mice.Compared with the control group,the phosphorylation levels of Tau protein Ser1 99,Ser396 and Ser202 sites in the hippocampus of mice in the AD model group were significantly in-creased(P＜0.01),the expression of PDE8A and PDE8B proteins was significantly increased(P＜0.01),and the expression of p-PKA/PKA and BDNF proteins was decreased(P＜0.05),after administra-tion of PF-04957325,the phosphorylation levels of Tau protein Ser396 and Ser202 sites were significantly re-duced(P＜0.01),PDE8A and PDE8B protein ex-pression was significantly decreased(P＜0.01),and p-PKA/PKA,p-CREB/CREB and BDNF protein ex-pression was significantly increased(P＜0.01).Con-clusion PDE8 inhibitor PF-04957325 can improve learning memory ability,reduce cognitive dysfunction,restore Tau protein function,and attenuate neuronal cell damage in the hippocampus of AD mice with amel-iorative effects.The mechanism of action may be relat-ed to the activation of PDE8/cAMP/CREB pathway and inhibition of Tau protein phosphorylation.

Objective:To understand the current status of human resources in Operating Room nursing in China, so as to provide reference for nursing management, human resource allocation, nursing education and training in Operating Rooms.Methods:Using the stratified sampling method, a self-made Operating Room nursing human resource survey questionnaire of Chinese Nursing Society was used as a research tool in July 2021 to investigate the general situation, surgical workload, human resource allocation, Operating Room management, Operating Room information construction, nursing education and training of 2 201 hospitals in 31 provinces, autonomous regions and municipalities of China.Results:Among the 2 201 hospitals, there were 1 021 tertiary hospitals (46.39%), 1 177 secondary hospitals (50.75%), and 63 primary and below hospitals (2.86%). There were 2 056 hospitals with less than 30 Operating Rooms, accounting for 93.41%. There were 1 991 hospitals with an annual number of surgical cases less than 20 000, accounting for 90.46%, the educational background of Operating Room nurses was mainly undergraduate (66.93%, 43 359/64 780), with a total of 67.99% (44 045/64 780) having a bachelor's degree or above. Nurses were the main professional titles (42.66%, 27 632/64 780). Number of Operating Rooms: the number of Operating Room nurses (median) was 1: 2.43 and 78.96% (1 738/2 201) of hospital operating theatres were managed by Nursing Departments or hospitals. A total of 1 479 hospitals (67.20%) established anesthesia recovery rooms in their Operating Rooms, which was higher than 59.34% (1 210 hospitals) surveyed in 2016, and the difference was statistically significant (χ 2=226.701, P<0.01). 74.69% (1 644/2 201) and 87.87% (1 934/2 201) of hospitals carried out post management and capacity classification management in Operating Rooms, respectively. Day surgery and robotic surgery were performed in 47.80% (1 052/201) and 7.68% (169/2 201) hospitals, respectively. 36.98% (814/2 201) of the hospitals passed the information evaluation system certification and 64.61% (1 422/2 201) of the hospitals used the Operating Room information management system. In the Operating Room information system of the hospital, 2.54% (56/2 201) had intelligent functions. And 77.24% (1 700/2 201) of hospitals participated in the qualification training of Operating Room specialist nurses. Conclusions:By July 2021, the number of Operating Rooms in most hospitals in China is less than 30, and the annual number of operating cases is less than 20 000. The educational background and professional title of Operating Room nurses are mainly undergraduate and nurse. More than 60% of hospitals have set up anesthesia recovery rooms and have information management systems for Operating Rooms. At the same time, Operating Rooms in Chinese hospitals have widely implemented diversified nursing management models such as post management and ability grading management.

Risk perception in patients with cardiovascular disease (CVD) can predict their adoption of health behaviors. A significant discrepancy between perceived risk and objective risk estimates can adversely affect individuals' risk response behaviors. This paper introduces the status quo of risk perception bias among CVD patients and analyzes the influencing factors from demographic factors, disease risk factors, individual psychological factors, socio-cultural factors, risk communication, and risk characteristics. It summarizes intervention strategies to reduce risk perception bias, aiming to enhance healthcare professionals' understanding of this issue in CVD patients and provide a reference for developing reasonable intervention measures in the future.
