Objective: To investigate the prevalence and influencing factors of depression among middle school students in Jiading District, Shanghai Municipality, so as to provide the evidence for developing mental health intervention strategies among middle school students. Methods: Students from 3 junior high schools and 3 senior high schools in Jiading District were selected from June 2022 to June 2023 using a stratified random cluster sampling method. Basic information including gender and educational stage was collected through questionnaire surveys. Depression, mental health literacy, cognitive emotion regulation, family cohesion, school climate, stress, and life satisfaction were assessed using the Children's Depression Inventory, the Mental Health Literacy Assessment Scale, the Chinese version of the Cognitive Emotion Regulation Questionnaire, the Family Adaptability and Cohesion Scale, the Perceived School Climate Scale, Depression-Anxiety-Stress Scale, and the Life Satisfaction Scale, respectively. Factors affecting depression among middle school students were analyzed using a multivariable logistic regression model. Results: There were 1 117 boys (53.94%) and 954 girls (46.06%), with a mean age of (15.20±1.77) years. There were 1 193 (57.61%) junior high school students and 878 (42.39%) senior high school students. Depression was detected in 577 students, with a prevalence of 27.86%. Multivariable logistic regression analysis identified gender (boy, OR=0.652, 95%CI: 0.512-0.832), educational stage (senior high school, OR=2.519, 95%CI: 1.584-4.008), mental health literacy (OR=0.958, 95%CI: 0.951-0.966), cognitive emotion regulation (adaptive cognitive emotion regulation strategies, OR=0.970, 95%CI: 0.958-0.982; maladaptive cognitive emotion regulation strategies, OR=1.103, 95%CI: 1.084-1.123), family cohesion (OR=0.910, 95%CI: 0.899-0.921), school climate (OR=0.720, 95%CI: 0.694-0.747), stress (OR=1.127, 95%CI: 1.104-1.150), life satisfaction (OR=0.817, 95%CI: 0.799-0.836) as factors affecting depression among middle school students. Conclusions Depression among middle school students in Jiading District is associated with gender, educational stage, mental health literacy, cognitive emotion regulation, family cohesion, school climate, stress, and life satisfaction. It is recommended that targeted measures be taken from the perspectives of individuals, families, schools, and society to promote the mental health of middle school students.

BACKGROUND: G protein-coupled receptor kinase 2 (GRK2) could participate in the regulation of diverse cells via interacting with non-G-protein-coupled receptors. In the present work, we explored how paroxetine, a GRK2 inhibitor, modulates the differentiation and activation of immune cells in rheumatoid arthritis (RA). METHODS: The blood samples of healthy individuals and RA patients were collected between July 2021 and March 2022 from the First Affiliated Hospital of Anhui Medical University. C57BL/6 mice were used to induce the collagen-induced arthritis (CIA) model. Flow cytometry analysis was used to characterize the differentiation and function of dendritic cells (DCs)/T cells. Co-immunoprecipitation was used to explore the specific molecular mechanism. RESULTS: In patients with RA, high expression of GRK2 in peripheral blood lymphocytes, accompanied by the increases of phosphatidylinositol 3 kinase (PI3K), protein kinase B (AKT), and mammalian target of rapamycin (mTOR). In animal model, a decrease in regulatory T cells (T regs ), an increase in the cluster of differentiation 8 positive (CD8 + ) T cells, and maturation of DCs were observed. Paroxetine, when used in vitro and in CIA mice, restrained the maturation of DCs and the differentiation of CD8 + T cells, and induced the proportion of T regs . Paroxetine inhibited the secretion of pro-inflammatory cytokines, the expression of C-C motif chemokine receptor 7 in DCs and T cells. Simultaneously, paroxetine upregulated the expression of programmed death ligand 1, and anti-inflammatory cytokines. Additionally, paroxetine inhibited the PI3K-AKT-mTOR metabolic pathway in both DCs and T cells. This was associated with a reduction in mitochondrial membrane potential and changes in the utilization of glucose and lipids, particularly in DCs. Paroxetine reversed PI3K-AKT pathway activation induced by 740 Y-P (a PI3K agonist) through inhibiting the interaction between GRK2 and PI3K in DCs and T cells. CONCLUSION Paroxetine exerts an immunosuppressive effect by targeting GRK2, which subsequently inhibits the metabolism-related PI3K-AKT-mTOR pathway of DCs and T cells in RA.

Pregnancy with chronic kidney disease (CKD), particularly in stages 4-5, carries high risks of adverse outcomes including maternal renal failure, preeclampsia/eclampsia, fetal growth restriction, and preterm birth. This report described a 26-year-old woman with congenital solitary kidney, polycystic ovaries, and uterine septum due to PAX2 gene variant, complicated by CKD stage 4. Through multidisciplinary team precision management and individualized treatment strategies, including timely initiation of dialysis, the patient successfully maintained pregnancy until 34 +1 weeks and delivered a female infant via cesarean section. This case summarizes key management experiences for end-stage renal disease in pregnancy, highlighting early risk assessment, precise nutritional management, hemodialysis protocol optimization, and the crucial role of multidisciplinary collaboration, providing valuable references for managing CKD-complicated pregnancies.

Objective:To explore the influence and mechanism of perceived school climate on life satisfaction of junior high school students.Methods:From June to September 2022, students in sixth, seventh and eighth grade of junior high school were surveyed by the perceived school climate scale, the family cumulative risk-related questionnaire, the cognitive emotion regulation strategy questionnaire and the life satisfaction scale.SPSS 25.0 software was used to process data and the macro program PROCESS 4.1 was used for model testing.Results:(1) The total scores of perceived school climate, negative cognitive emotion regulation strategy, life satisfaction and family cumulative risk were 83.00(19.00), 21.00(8.00), 23.00(9.00) and 1.00(2.00), respectively.(2) Perceived school climate was significantly and negatively correlated with negative cognitive emotion regulation strategy and family cumulative risk( r=-0.30, -0.40, both P<0.01), while significantly and positively correlated with life satisfaction ( r=0.51, P<0.01).Negative cognitive emotion regulation strategy was significantly and negatively correlated with life satisfaction ( r=-0.37, P<0.01), while significantly and positively correlated with family cumulative risk ( r=0.29, P<0.01). Family cumulative risk was significantly and negatively correlated with life satisfaction ( r=-0.45, P<0.01). (3) Negative cognitive emotion regulation strategy played a mediating role between perceived school climate and life satisfaction, and the mediating effect accounted for 13.46%(0.07/0.52) of the total effect. (4) Family cumulative risk played a moderating role in the relationship between perceived school climate and life satisfaction, and between perceived school climate and negative cognitive emotion regulation strategy. Specifically, as the level of family cumulative risk decreased, the positive predictive effect of perceived school climate on life satisfaction significantly increased ( βsimple=0.42, P<0.001). Perceived school climate significantly and negatively predicted negative cognitive emotion regulation strategy under the condition of low level family cumulative risk ( βsimple=-0.30, P<0.001). Conclusion:Under the condition of low family cumulative risk in junior high school students, the perceived positive school climate can help reduce negative cognitive emotion regulation strategy, thereby improving life satisfaction.

The authors elaborate on the anti-tumor biological mechanisms of radiotherapy, review the current research status of radiotherapy in preoperative treatment of resectable gastric cancer, and analyze existing challenges to explore future trends in neoadjuvant radiotherapy for gastric cancer and propose reflections on related issues. Through multidisciplinary integration and technological advance-ments, it is anticipated that the conceptual framework of radiotherapy for gastric cancer will evolve, achieving precision and individualization in radiotherapy to provide patients with more definitive survival benefits.

Objective:To analyze the therapeutic effect of ganglioside combined with hyperbaric oxygen in the treatment of cerebral hemorrhage. To investigate the effects of ganglioside combined with hyperbaric oxygen therapy on serum inflammatory factors and neural injury markers in patients.Methods:A randomized controlled study was conducted involving 98 patients with cerebral hemorrhage treated at Bayannur Hospital from January 2022 to January 2024. The patients were randomly assigned to either a control group or a combination group, with 49 cases in each group, using a random number table method. All patients received routine treatment. The control group received hyperbaric oxygen therapy, while the combination group received both hyperbaric oxygen therapy and ganglioside therapy. Both groups were treated for 20 days. The volume of cerebral edema, levels of serum inflammatory factors, and neural injury markers were compared between the two groups before and after treatment, and the efficacy of both groups was evaluated.Results:After treatment, the brain edema volume in the combination group [(12.31 ± 1.31) cm3]was significantly lower than that in the control group [(15.36 ± 1.62) cm3, t = 10.25, P < 0.05]. The Glasgow Coma Scale score in the combination group [(13.64 ± 1.37) points] was significantly higher than that in the control group [(11.42 ± 1.24) points, t = -8.41, P < 0.05]. The serum levels of interleukin-1β and interleukin-8 in the combination group were (5.48 ± 0.56) ng/L and (12.29 ± 1.33) ng/L, respectively, both of which were significantly lower than those in the control group [(6.42 ± 0.67) ng/L, (16.85 ± 1.71) ng/L, t = 7.54, 14.74, both P < 0.05]. The levels of soluble protein-100β (S100β) and high mobility group protein-1 in the combination group were (0.62 ± 0.07) μg/L and (4.17 ± 0.42) μg/L, respectively, both of which were significantly lower than those in the control group [(0.81 ± 0.09) μg/L, (5.59 ± 0.56) μg/L, t = 11.67, 14.20, both P < 0.05]. The National Institutes of Health Stroke Scale score in the combination group [(11.47 ± 1.23) points]was significantly lower than that in the control group [(15.31 ± 1.62) points, t = 13.22, P < 0.05]. The Fugl-Meyer Assessment of Motor Recovery after Stroke score in the combination group [(63.58 ± 6.48) points] was significantly higher than that in the control group [(54.64 ± 5.71) points, t = -7.25, P < 0.05]. The total response rate in the combination group was 91.84% (45/49), which was significantly higher than that in the control group [73.47% (36/49), χ2 = 5.76, P < 0.05]. Conclusions:The use of gangliosides in combination with hyperbaric oxygen therapy for the treatment of cerebral hemorrhage can effectively reduce cerebral edema, lessen inflammatory responses, and minimize neural injury. This approach helps restore patients' neurological and motor functions and enhance overall treatment efficacy.
