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 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.

Objective To investigate the effect of dioscin on uric acid(UA)-induced oxidative stress injury of human renal tubular epithelial cells(HK-2)and its molecular mechanism.Methods HK-2 cells were cultured and divided into four groups:blank group(normal group),model group(uric acid-stimulation modeling),condition control group(UA+DMSO)and dioscin group(UA+dioscin).Oxidative stress injury model was induced by UA in HK-2 cells.Cells viability was detected by CCK-8.ROS level was detected by flow cytometry.Real-time PCR was used to detect the expressions of glycogen synthase kinase 3β(GSK3β),nuclear factor erythroid 2-related factor 2(Nrf2)and heme oxygenase 1(HO-1)at mRNA level,and Western Blot was used to detect the expressions of phosphorylated glycogen synthesis kinase 3β(p-GSK3β),GSK3β,Nrf2 and HO-1 at protein level.Results After stimulation by UA,HK-2 cells viability was obviously decreased,and ROS level was significantly increased(all P＜0.001).When treated with dioscin,HK-2 cells viability was obviously increased,and the ROS level of HK-2 cells was significantly decreased(all P＜0.001).The expressions of Nrf2 and HO-1 decreased at the protein and mRNA levels after stimulation with UA.But the expressions of Nrf2 and HO-1 significantly increased after treated with dioscin(all P＜0.001).Compared with the blank group,the p-GSK3β/GSK3β ratio in the model group decreased significantly at the protein level,but the p-GSK3β/GSK3β ratio increased after treated with dioscin(all P＜0.001).Conclusion Dioscin can alleviate UA-induced oxidative stress injury in HK-2 cells.The mechanism might be that dioscin can promote phosphorylation of GSK3β,and activate Nrf2/HO-1 pathway.
