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.

Objective:To explore the locations of the lumbosacral nerve roots by use of the magnetic stimulation.Methods:Thirty healthy subjects were studied. The projections of the right L 2 to S 1 intervertebral foramina on their body surfaces were determined manually with ultrasound assistance. Magnetic stimulation was applied to different nerve root segments to induce compound muscle action potentials (CMAP) in the vastus medialis, tibialis anterior, and gastrocnemius muscles of the lower limbs. The changes in latency, amplitude, and motor threshold were observed. Results:Magnetic stimulation on the L 2-L 3 segment resulted in a significant direct excitation of the vastus medialis. That on the L 5-S 1 segment evoked a significant direct excitatory effect on the tibialis anterior and gastrocnemius, with a motor threshold below 40%, an amplitude exceeding 1mV, and many effective responses. However, during the magnetic stimulation on the L 4 segment, the amplitude of the vastus medialis was above 1mV, with no significant differences in the number of effective responses among the muscle groups. Moreover, there was a stepwise change in the latency of effective muscle responses to magnetic stimulation at different segments. The CMAP latencies of 12+ ms for the tibialis anterior and 13+ ms for the gastrocnemius indicated activation of the L 5 and L 4 nerve roots, respectively, while those of 6+ ms, 7+ ms, and 8+ ms for the vastus medialis suggested activation of the L 4, L 3, and L 2 nerve roots, respectively. Conclusions:Based on the responses (CMAP latency, amplitude and motor threshold) of the vastus medialis, tibialis anterior and gastrocnemius to magnetic stimulation at different L 2 to S 1 segments, the spinal nerve root segments responsible for innervation can be inferred.

Heart failure(HF)is a highly morbid syndrome that seriously affects the physical and mental health of patients and generates an enormous socio-economic burden.In addition to cardiac myocyte oxidative stress and apoptosis,which are considered mechanisms for the development of HF,alterations in cardiac energy metabolism and pathological autophagy also contribute to cardiac abnormalities and ultimately HF.Silent information regulator 1(Sirt1)and adenosine monophosphate-activated protein kinase(AMPK)are nicotinamide adenine dinucleotide(NAD+)-dependent deacetylases and phosphorylated kinases,respectively.They play similar roles in regulating some pathological processes of the heart through regulating targets such as peroxisome proliferator-activated receptor γ coactivator 1α(PGC-1α),protein 38 mitogen-activated protein kinase(p38 MAPK),peroxisome proliferator-activated receptors(PPARs),and mammalian target of rapamycin(mTOR).We summarized the synergistic effects of Sirt1 and AMPK in the heart,and listed the traditional Chinese medicine(TCM)that exhibit cardioprotective properties by modulating the Sirt1/AMPK pathway,to provide a basis for the development of Sirt1/AMPK activators or inhibitors for the treatment of HF and other cardiovascular diseases(CVDs).

ObjectiveTo understand the utilization of preconception healthcare services and the influencing factors among the women expecting additional childbirth in Jiading District， Shanghai， and to provide references for promoting the utilization of preconception healthcare services under the new population policy. MethodsA questionnaire survey on the utilization of preconception healthcare services and related influencing factors was carried out among 682 women expecting additional childbirth across six subdistricts in Jiading District， Shanghai. The results were statistically analyzed. ResultsThe average age of the women was （31.7±4.5） years， 30.2% of whom were ≥35 years old. The proportion of women having their third or subsequent children was low， at 16.4%. A significant majority， 92.4%， were found to have various risk factors during initial pregnancy screening. The utilization rate of preconception healthcare services among women seeking additional childbirth was relatively low at 26.7%. Awareness of the free preconception check-up program in Jiading District was also low at 28.6%， and the utilization rate for these services was even lower at 7.69%. Unplanned pregnancies were the primary reason for not utilizing preconception healthcare services， accounting for 63.6%. The results of multifactorial binary logistic regression analysis showed that the utilization rate of preconception healthcare services before the current pregnancy was higher for women aged between 35 and 39 compared to women aged ≤29 years old （OR=1.789， 95%CI： 1.033‒3.099）. Women with planned pregnancies had a higher utilization of preconception healthcare services prior to this pregnancy （OR=4.164， 95%CI： 2.627‒6.602）. Women who had received preconception care prior to their first birth had a higher utilization rate of preconception care prior to the current pregnancy （OR=7.534， 95%CI： 4.954‒11.456）. Women without a family history of chronic diseases had a higher utilization rate of preconception healthcare services （OR=1.903， 95%CI： 1.083‒3.345）. ConclusionUnder the context of three-child policy， the proportion of women seeking three or more children in Jiading District is low. Most of these women have risk factors identified during initial pregnancy screenings. The utilization rate of preconception healthcare services and the awareness of the free preconception screening program in Jiading District are both low. Unplanned pregnancies remain the primary reason for failing to receive timely preconception healthcare services. Age， whether the pregnancy was planned， whether the women had received preconception healthcare services before their first baby and family history of chronic diseases are the main factors affecting the utilization of preconception healthcare services. Relevant departments should enhance the promotion of preconception healthcare service programs， especially for women of childbearing age who have not yet given birth， so as to improve the utilization rate of preconception health care services.

Objective:To compare the short-term efficacy of Kamikawa anastomosis and double-tract reconstruction (DTR) after proximal gastrectomy.Methods:This was a propensity score matched, retrospective, cohort study. Inclusion criteria comprised age 20–70 years, diagnosis of gastric cancer by pathological examination of preoperative endoscopic biopsies, tumor diameter ≤4 cm, and location in the upper 1/3 of the stomach (including the gastroesophageal junction), and TNM stage IA, IB, or IIA. The study cohort comprised 73 patients who had undergone laparoscopic proximal gastric cancer radical surgery in the Department of Gastroenterology, Tangdu Hospital, Air Force Medical University between June 2020 and February 2023, 19 of whom were in the Kamikawa group and 54 in the DTR group. After using R language to match the baseline characteristics of patients in a ratio of 1:2, there were 17 patients in the Kamikawa group and 34 in the DTR group. Surgery-related conditions, postoperative quality of life, and postoperative complications were compared between the two groups.Results:After propensity score matching, there were no statistically significant differences in baseline data between the two groups ( P>0.05). Compared with the DTR group, the Kamikawa group had longer operative times (321.5±15.7 minutes vs. 296.8±26.1 minutes, t=32.056, P<0.001), longer anastomosis times (93.0±6.8 minutes vs. 45.3±7.7 minutes, t=56.303, P<0.001), and less bleeding (76 [54~103] mL vs.112 [82~148) mL, Z=71.536, P<0.001); these differences are statistically significant. There were no statistically significant differences between the two groups in tumor size, time to first postoperative passage of gas, postoperative hospital stay, number of lymph nodes removed, duration of lymph node dissection, or total hospitalization cost (all P>0.05). The median follow-up time was 6.1 ± 1.8 months. As to postoperative quality of life, the Kamikawa group had a lower rate of upper gastrointestinal contrast reflux than did the DTR group (0 vs. 29.4% [10/34], χ 2=6.220, P=0.013); this difference is statistically significant. However, differences between the two groups in quality of life score on follow-up of 3 months and 6 months on the Gastroesophageal Reflux Disease (GERD) scale were not statistically significant (all P>0.05). The incidence of postoperative complications was 2/17 in the Kamikawa group, which is significantly lower than the 41.2% (14/34) in the DTR group (χ 2=4.554, P=0.033). Conclusion:Kamikawa anastomosis and DTR are equally safe and effective procedures for reconstructing the digestive tract after proximal gastric surgery. Although Kamikawa anastomosis takes slightly longer and places higher demands on the surgical team, it is more effective at preventing postoperative reflux.

Objective:To investigate the effect of neoadjuvant chemotherapy on the safety of laparoscopic D 2 radical resection and prognosis of patients with locally advanced gastric cancer. Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 351 patients with locally advanced gastric cancer who underwent laparos-copic D 2 radical resection in the Second Affiliated Hospital of Air Force Medical University from December 2016 to December 2021 were collected. There were 256 males and 95 females, aged (58±9)years. Of the 351 patients, 124 cases undergoing neoadjuvant chemotherapy were divided into the neoadjuvant chemotherapy group, 227 patients undergoing postoperative adjuvant chemotherapy were divided into the adjuvant chemotherapy group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) effect evaluation of neoadjuvant chemotherapy; (3) intraoperative and postoperative situations; (4) postoperative histopathological examinations; (5) follow-up. Propensity score matching was done by the 1∶1 nearest neighbor matching method. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measure-ment data with skewed distribution were represented as M(range) or M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to draw survival curves, and the Log-Rank test was used for survival analysis. Results:(1) Propensity score matching conditions and comparison of general data of patients between the two groups of patients after matching. Of 351 patients, 154 cases were successfully matched, including 77 cases in the neoadjuvant chemotherapy group and 77 cases in the adjuvant chemotherapy group. The elimination of gender, age, preoperative body mass index, clinical T staging and clinical N staging confounding bias ensured comparability between the two groups after propensity score matching. (2) Effect evaluation of neoadjuvant chemotherapy. Of the 77 patients receiving neoadjuvant chemotherapy, none of patient achieved complete response, 26 patients achieved partial response, 46 patients showed stable disease, 5 patients had progression of disease, showing the objective response rate as 33.8%(26/77) and the disease control rate as 93.5%(72/77). There were 15 males and 11 females sensitive to neoadjuvant chemotherapy, while 46 males and 5 females not sensitive, showing a significant difference between them ( χ2=11.05, P<0.05). (3) Intra-operative and postoperative situations. The operation time, volume of intraoperative blood loss, cases with intraoperative blood transfusion, time to postoperative first flatus, time to postoperative first liquid food intake, duration of postoperative hospital stay, cases with postoperative immediate complications, cost of hospital stay were (308±71)minutes, 100(range, 20?600)mL, 5, 3.0(range, 2.0?10.0)days, 4.0(range, 2.0?12.0)days, 9.0(range, 4.0?31.0)days, 7, 7.96(7.37,8.58) ten thousand yuan in patients of the neoadjuvant chemotherapy group, versus (296±67)minutes, 100(range, 20?500)mL, 4, 3.5(range, 1.0?14.0)days, 4.0(range, 2.0?15.0)days, 8.0(range, 5.0?45.0)days, 11, 8.18(7.52,9.19) ten thousand yuan in patients of the adjuvant chemotherapy group, showing no signifi-cant difference in the above indicators between the two groups ( t=1.13, Z=?0.37, χ2=0.12, Z=?1.26, ?0.33, ?0.70, χ2=1.01, Z=?1.04, P>0.05). (4) Postoperative histopathological examinations. Results of postoperative histopatho-logical examinations showed that all 154 patients achieving R 0 resection. Cases with pathological T staging as stage T1, stage T2, stage T3, stage T4, cases with pathological N staging as stage N0, stage N1, stage N2, stage N3, number of positive lymph nodes, cases with human epidermal growth factor receptor 2 (negative, positive) were 3, 7, 5, 62, 27, 19, 19, 12, 1(range, 0?28), 59, 18 in patients of the neoadjuvant chemotherapy group, versus 0, 0, 2, 75, 17, 15, 21, 24, 3(range, 0?31), 44, 33 in patients of the adjuvant chemotherapy group, showing significant differences in the above indicators between the two groups ( Z=?3.39, ?2.55, ?3.12, χ2=6.60, P<0.05). (5) Follow-up. Of the 154 patients, 143 patients were followed up for 37(range, 5?69)months. The 3-year overall survival rate and 3-year disease-free survival rate was 72.1% and 70.0%, respectively, in patients of the neoadjuvant chemotherapy group, versus 74.8% and 76.6% in patients of the adjuvant chemo-therapy group, showing no significant difference in the above indicators between the two groups ( χ2=0.14, 0.60, P>0.05). Conclusions:Compared to postoperative adjuvant chemotherapy, neoadjuvant chemotherapy does not bring additional surgical risks, but can reduce the tumor stage of patients who underwent laparoscopic D 2 radical resection for locally advanced gastric cancer. However, it does not show any advantage in improving survival of patients.

Objective:To study the effect of ranibizumab on retinal oxidative stress in a rat model of choroidal neovascularization (CNV) and its mechanism.Methods:Sixty SPF male SD rats aged 10 weeks were randomly divided into normal control group, model control group, ranibizumab group, nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor (ML385) group, ranibizumab+ ML385 group, with 12 rats in each group according to a random number table.Except for the normal control group, the CNV model was established in the other four groups via krypton laser induction.According to grouping, the ranibizumab group, ML385 group and ranibizumab+ ML385 group were intravitreally injected with 1 μl of ranibizumab, ML385 and ranibizumab+ ML385, respectively.Model control group and normal control group received an intravitreal injection of normal saline of equal volume.The CNV area was measured through choroidal wholemounts.Pathological change of the retina was observed by hematoxylin and eosin staining.Expressions of Nrf2, superoxide dismutase (SOD) and quinone oxidoreductase 1 (NQO1) were detected using Western blot and real-time PCR.The use and care of animals complied with laboratory animal welfare guidelines.The study protocol was approved by the Laboratory Animal Welfare and Ethics Committee of Tengzhou Central People's Hospital (No.JN.No20210214S1200430[121]).Results:CNV areas of the model control group, ML385 group and ranibizumab+ ML385 group were (23.01±1.52)×10 3, (30.23±2.01)×10 3 and (18.56±1.85)×10 3 μm 2, respectively, which were significantly higher than (12.35±1.22)×10 3 μm 2 of ranibizumab group (all at P<0.001). The CNV area of ranibizumab+ ML385 group was smaller than that of model control group and ML385 group, and the CNV area of ML385 group was larger than that of model control group, showing statistically significant differences (all at P<0.001). Hematoxylin and eosin staining showed that the structural damage of the retinal pigment epithelium-choroid-sclera complex was slighter in ranibizumab group than model control group, severer in ranibizumab+ ML385 group than ranibizumab group but slighter than model control group, severer in ML385 group than model control group.The mRNA and protein expressions of Nrf2, SOD and NQO1 of ranibizumab group were lower than those of normal control group but higher than those of model control group, ML385 group and ranibizumab+ ML385 group, and the differences were statistically significant (all at P<0.05). The mRNA and protein expressions of Nrf2, SOD and NQO1 were higher in ranibizumab+ ML385 group than model control group and ML385 group, showing statistically significant differences (all at P<0.05). Conclusions:Ranibizumab can inhibit the growth of CNV induced by krypton laser and reduce RPE damage caused by retinal oxidative stress.The mechanism is related to the activation of Nrf2/ARE pathway.
