BackgroundIn recent years， the incidence of depression among adolescents has been increasing steadily， posing a serious threat to their physical and mental health and even leading to severe consequences such as self-harm and suicide. At the same time， the detection rate of subclinical depression symptoms among adolescents is even higher. Although these symptoms do not meet the clinical diagnostic criteria， they have significantly affected their quality of life， and their persistence over time may further develop into depression. Therefore， in-depth exploration of adolescent depression symptoms and the predictive factors holds significant practical significance and research value. However， up to now， no large-scale investigation and research on depression symptoms among children and adolescents has been conducted in Inner Mongolia Autonomous Region. ObjectiveTo understand the prevalence of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region， in order to provide references for formulating scientific and effective prevention strategies and intervention measures. MethodsBy using the cluster stratified random sampling method， 6 281 students from the third grade of primary school to the second grade of high school in 12 leagues and cities of Inner Mongolia Autonomous Region were selected in March 2024. A self-designed questionnaire and the Self-rating Depression Scale （SDS） were used for on-site investigation. ResultsA total of 6 058 （96.45%） children and adolescents completed the valid questionnaire survey， and 2 728 cases （45.03%） were found to have depressive symptoms. There were statistically significant differences in the detection rates of depressive symptoms among children and adolescents of different genders， ages， whether they were only children， different family types， family monthly income， parents' educational levels， and whether the mother was employed （χ²=33.769， 40.618， 48.593， 29.972， 142.648， 195.999， 168.190， 5.445， P<0.05 or 0.01）.The results of the Logistic regression analysis showed that for children and adolescents， being female， aged between 12 and 16， over 16 years old， not being an only child， living in a reconstituted family， having a monthly family income of less than 5 000 yuan， and having parents with an education level of primary school or below were predictors of depressive symptoms （OR=1.241， 1.427， 1.273， 1.177， 1.549， 1.278， 1.462， 1.417， 1.514， 1.929， 1.660， 1.528， P<0.05 or 0.01）. ConclusionThe detection rate of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region is relatively high. Factors that may predict depressive symptoms in children and adolescents include female gender， ages between 12 and 16， ages over 16 years old， non-only children， families with a restructured structure， monthly family income of less than 5 000 yuan， and parents with an education level of primary school or below. ［Funded by Science and Technology Planning Project of the Inner Mongolia Autonomous Region （number， 2022YFSH0119）］

Cucurbitacin B has been demonstrated to exhibit significant antitumor activity against various types of tumors. Its antiproliferative effects were mediated through the regulation of multiple signaling pathways， including the Janus kinase 2/signal transducer and activator of transcription 3 （STAT3） pathway， the phosphoinositide 3-kinase/protein kinase B pathway， and the mitogen-activated protein kinase pathway. Diverse forms of cell death were induced by modulating the expression of proteins such as B-cell lymphoma-2-associated X protein， Notch signaling components， iron uptake regulatory proteins， and gasdermin D. Genetic effects were exerted through upregulation of phosphorylated histone H2AX expression and suppression the expression of oncogenes. Furthermore， the tumor immune microenvironment was modulated， angiogenesis and migration/invasion were inhibited， and tumor drug resistance was ameliorated via targeting of the STAT3 site， inhibition of vascular endothelial growth factor receptor 2， and downregulation of P-glycoprotein. However， the oral bioavailability of cucurbitacin B has been found to be low； therefore， various strategies， including the development of derivatives and prodrugs， construction of nano-drug delivery systems， and fabrication of molecular probes， have been employed to improve its utilization efficiency and safety. In the future， more in-depth mechanistic investigations and clinical trials are still required to provide a theoretical basis for novel drug development and clinical application of this compound.

As a cutting-edge technology in minimally invasive surgery,single-port robotic surgery systems have demonstrated significant advantages in gynecology.This study reviewed 22 clinical research papers on the application of single-port robotic surgery in gynecology,involving 2 130 patients.The data indicated that,compared with conventional surgery,single-port robotic surgery had advantages such as a shorter learning curve,reduced intraoperative blood loss,improved cosmetic outcomes,and fewer postoperative complications,particularly in managing benign conditions like uterine fibroids.However,its application in gynecological malignancies remains challenging.Future research will require large-scale,multicentre studies with long-term follow-up to validate long-term efficacy.Advancing novel materials and integrating artificial intelligence with single-port robotic systems will help overcome current limitations,propelling gynecological surgery towards greater precision and minimally invasive techniques.

Objective:To describe the prevalence of anxiety disorders and its distribution in Inner Mongolia Autonomous Region,and to explore the relevant factors of anxiety disorders.Methods:From June 2019 to Decem-ber 2019,representative multi-stage disproportionate stratified sampling procedure was used to sample in residents aged 18 and over in the Inner Mongolia Autonomous Region.All respondents were face-to-face interviewed by trained interviewers.Composite International Diagnostic Interview-3.0(CIDI-3.0)was used to diagnose anxiety disorders according to the criteria and definition of the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ).Chi-square test and multivariate logistic regression analysis were used for statistical anal-ysis.Results:Totally 12 315 people were interviewed in the survey.The weighted 12-mouth prevalence rate of any anxiety disorder was 4.64％,and the lifetime prevalence rate was 6.25％.The weighted 12-month prevalence rate of anxiety disorders was higher in female than that in male(5.38％vs.3.92％).The rate was higher in rural resi-dents than that in urban residents(5.67％vs.3.95％).The rate was higher in people with chronic diseases than that in people without chronic diseases(6.81％vs.2.29％).Logistic regression analysis showed that unmarried(OR=2.32,95％CI:1.31-4.10),separated/divorced(OR=2.49,95％CI:1.33-4.67),in debt(OR=1.55,95％CI:1.04-2.32),chronic disease(OR=2.22,95％CI:1.39-3.53),family history of anxiety disorders(OR=12.05,95％CI:8.78-16.53),poor sleep(OR=2.64,95％CI:1.97-3.54)were risk factors of occurrence of anxiety disorders,while junior high school(OR=0.65,95％CI:0.44-0.96)was protective factor of anxiety disor-ders.Conclusion:Adults with chronic diseases,poor sleep,unmarried or separated/divorced,family history of anxi-ety disorders,and financial debt are at higher risk groups of anxiety disorder in Inner Mongolia Autonomous Re-gion.

Objective:To describe the prevalence and distributions of mood disorder in Inner Mongolia Au-tonomous Region,and analyze the related risk factors.Methods:The multistage stratified sampling method with un-equal probability was used to select permanent residents aged 18 years and over in Inner Mongolia Autonomous Re-gion.The Composite International Diagnostic Interview 3.0 was used as a diagnostic tool.Mood disorders were di-agnosed according to the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition(DSM-Ⅳ).Single and multivariate analyses were used to investigate the related factors of mood disorders.Results:Totally,12 315 community residents were interviewed in the survey.The weighted 12-month prevalence and lifetime prevalence of mood disorder were 5.4％and 8.7％,respectively.Weighted 12-month prevalence of depressive disorder was 4.9％,and that of bipolar disorder was 0.3％.Among all subtypes of mood disorder,the 12-month prevalence rate of major depressive disorder(3.1％)was the highest.Multivariate logistic regression analysis showed that female,unmarried,separated or divorced,unemployment,family history,other mental disorders,sleep disorders and chronic diseases(OR=1.56,2.80,2.07,1.42,13.46,7.97,3.23,2.13)were risk factors of mood disorder,while aged 65 years and over(OR=0.44)was protective factor of mood disorders.The lifetime consultation rate in patients with mood disorders was 15.5％,the rate of psychiatric consultation was 3.7％,the rate of medication was 1.8％.Con-clusion:It indicates that female residents and people who are unmarried,separated and divorced,unemployed,with family history,suffering from other mental disorders,suffering from sleep disorders,and suffering from chronic dis-eases may be high risk groups of mood disorders,and the utilization rate of health services is rather low in Inner Mongolia Autonomous Region.

Objective:To evaluate the clinical efficacy and safety of Pazopanib in maintenance therapy after platinum-resistant recurrence of ovarian cancer.Methods:A total of 80 patients with platinum-resistant recurrence of ovarian cancer treated in Sichuan Friendship Hospital from January 2018 to January 2024 were selected as the study objects.All patients were given paclitaxel or gemcitabine monotherapy for 6-8 cycles and entered mainte-nance therapy after the patients achieved complete response(CR)or partial response(PR).They were divided into a study group(38 cases)and a control group(42 cases)using a simple randomization method.The study group was given pazopanib maintenance treatment,and the control group was given compound cantharides cap-sule maintenance treatment.The treatment time lasted until the disease progressed.Progression-free survival(PFS),serum CA125 level,1-year survival rate,and adverse drug reactions were compared between the two groups.Results:Compared with the control group,PFS(12.84±6.23 months vs.6.12±4.82 months)and 1-year survival rate(73.68%vs.45.24%)in the study group were higher than those in the control group,the difference was statistically significant(P<0.05).The serum CA125 level of the study group was lower than that of the control group after 3 months of maintenance treatment and when the tumor recurred again,and the difference was statis-tically significant(P<0.05).The overall incidence of adverse drug reactions in the study group was higher than that in the control group(52.63%vs.21.42%,P<0.05),but mainly chronic diarrhea,hair loss and hypopigmenta-tion.Conclusions:In the maintenance treatment after recurrence of platinum-resistant patients with ovarian canc-er,oral pazopanib can effectively prolong the disease progression-free period of patients with few side effects,high safety,and strong patient compliance.
