Objective To observe the effects of passive movement on the functional outcome after occlusion of the middle artery in the brain and reperfusion, and to explore the molecular mechanisms involved. Methods Cerebral infarction models were established in rats using left middle cerebral artery occlusion ( MCAO). The survivors were randomly divided into a passive movement group and a natural recovery group. There was also a sham-operated group and a normal group. Passive movement treatment (twice a day, twenty min per time) was started at different times after reperfusion. The expression of brain-derived neurotrophic factor (BDNF) and B cell lymphoma/leukemia-2 gene (Bcl-2) were determined using real-time PCRs. Results Expression of BDNF and Bcl-2 was detected a-round the infarction area in both groups. The expression of BDNF and Bcl-2 was highest in the sub-groups where passive movement was begun 24 or 48 h after the operation. Conclusions The expression of BDNF and Bcl-2 in the brain peaks when daily, moderate intensity passive movement is administered beginning 24 to 48 h after reperfusion. Passive movement might have a protective and rehabilitative effect after cerebral infarction.

Objective To investigate the effect of Exendin-4 (Ex-4) on ischemia/reperfusion (I/R) injury-induced apoptosis in primary rat cortical neurons and the possible underlying mechanisms.Methods Rat cortical neurons were cultured in vitro,identified by NES-immunohistological staining and immunofluorescence staining,and randomly divided into the following groups: control group,I/R group and Ex-4 group.RT-PCR was performed to establish the existence of active glucagon-like peptide-1 receptor (GLP-1R).ELISA was used to measure the neuronal cytoplasmic cAMP level. MTT was used to detect viability. Fluorescent DNA binding dye Hoechest 33258 was used to reveal apoptosis. C/EBP-homologous protein (CHOP) and growth arrest and DNA-damage-inducible gene 34 (GADD34) mRNAs were detected by real-time PCR. Results The apoptosis rate induced by ischemia 6 h/reperfusion 12 h was 77.0% ±5.3% and was decreased to 27.0% ± 3.5% after Ex-4 ( 0. 4 μg/ml ) treating ( t = 19. 462,P ＜ 0. 01 ).Levels of CHOP and GADD34 mRNA in cortical neurons increased since 4 h and peaked at 12 h after reperfusion. Ex-4 group showed a sharp elevation of levels of CHOP and GADD34 mRNA,peaking at 8 h reperfusion,and then tended to decrease.Conclusions Ex-4 has protective effect against rat cortical neurons injury induced by ischemia/reperfusion. The protective effect may be related to inhibition of ESR-related neuron apoptosis via regulation of unfolded protein response.

Objective To study the effect of transcranial magnetic stimulation (TMS) on the rehabilitation of rats with cerebral infarction. Methods One hundred Sprague-Dawley rats were randomly divided into a normal group, a sham-operated control group, a model group and a TMS group with 25 rats in each group. A cerebral infarction model was established in the latter two groups by left middle cerebral artery occlusion (MCAO). TMS was started at either 12 or 24 hours after reperfusion, and sham-TMS was given to the first two groups at the same time points. The expression of Bcl-2 mRNA and BDNF mRNA were measured by RT-PCR after 14 days. Results Bcl-2 mRNA and BDNF mRNA were detected in all groups. The expression of Bcl-2 mRNA in the TMS-12 h group, and that of BDNF mRNA in the TMS-24 h group were significantly higher than in the other groups. Conclusions The expression of Bcl-2 mRNA and BDNF mRNA in the brains of rats after cerebral infarction peak when TMS is administered 12 h and 24 h after reperfusion, respectively. TMS might have protective and rehabilitative effects on rats after cere-bral infarct.

Objective To study the effect of electroacupuncture (EA) combined with transcranial magnetic stimulation (TMS) on the expression of the B-cell lymphoma/leukemia-2 gene (Bcl-2) and brain derived neurotrophic factor (BDNF) after cerebral infarction. Methods One hundred Sprague-Dawley rats were randomly and equally divided into a normal group, a sham-operated control group, a model group and an EA plus TMS group. A cerebral infarction model was established in the latter two groups using left middle cerebral artery occlusion (MCAO). Five-member subgroups of the EA plus TMS group were then treated at 6, 12, 24,48 and 72 hours after reperfusion. Sham EA plus TMS was given to similar sub-groups from the other groups at the same time points. The expression of Bcl-2 mRNA and BDNF mRNA were measured using a RT-PCR at the 14th day. Results Positive expression of Bcl-2 mRNA and BDNF mRNA was detected around the infarction in all groups. The average expression of both was significantly higher in the EA plus TMS group than in the model group. Bcl-2 mRNA peaked when the therapy was administered at 24 hours and BDNF mRNA at 48 hours.Conclusions The expression of Bcl-2 mRNA and BDNF mRNA is maximized when EA plus TMS is administered 24-48 hours after cerebral infarction. EA plus TMS does have protective and rehabilitative effects on rats after cerebral infarction.

Objective : To systematically evaluate the incidence of suicide ideation among HIV/AIDS patients in China, so as to provide insights into prevention of suicidal behaviors among HIV/AIDS patients. Methods : All publications pertaining to suicide ideation were jointly retrieved in electronic databases from database creation to May 22, 2022, including CNKI, CMB, Wanfang Data, VIP, PubMed and Web of Science. The quality of literatures was evaluated using the 11 quality indicators for cross-sectional studies recommended by the United States Agency for Healthcare Research and Quality (AHRQ), and a meta-analysis was performed using the software Stata 16.0. The stability of the study results was evaluated using sensitivity analysis, and the publication bias was evaluated using Begg's test. Results : A total of 1 557 publications were screened and 32 literatures covering 12 917 HIV/AIDS patients were included in the final analysis, including 21 Chinese publications and 11 English publications, and 19 high-quality publications and 13 moderate-quality publications. Meta-analysis showed that the incidence of suicide ideation was 30.3% (95%CI: 23.2%-37.4%) among HIV/AIDS patients in China, and subgroup analysis showed higher incidence of suicide ideation in unemployed HIV/AIDS patients than in employed patients (P<0.05). Sensitivity analysis showed stable study results, and Begg's test revealed no significant publication bias. Conclusions The incidence of suicide ideation is 23.2% to 37.4% among HIV/AIDS patients in China. High attention paid to psychological health and early psychological interventions are required to prevent the development of suicide ideation.

Objective: To investigate the effects of after school exercise service (referred to as the "after school ES") on physical health, so as to provide evidence for possible beneficial effect of after school ES. Methods: Students in the fourth grade of primary school were recruited from September 2021 to July 2022 in Changsha City and divided into the control group ( n =220) and the after school ES group ( n =220). The control group only participated in the regular physical education activities of the school. The after school ES group received after school ES for one academic year, 4 times a week, 40-50 minutes per time, for a total of 32 weeks. Body shape indicators such as height, weight and percentage of body fat, as well as physical fitness indicators such as 50 meter running, grip strength and progressive aerobic cardiovascular endurance run (PACER) were measured in September to October 2021 and June to July 2022, respectively. Independent sample t-test, Chi square test and two factors repeated measurement analysis of variance were used for statistical analysis of the data. Results: After one academic year, compared with the control group [(13.52±2.30)kg], muscle mass of primary school students in the after school ES group [(13.76±2.32)kg] significantly increased, while waist to hip ratio [(0.95±0.16)] and percentage of body fat [(20.17±7.43)%] significantly decreased compared to the control group [(1.01±0.21), (22.02±12.34)%]( F=330.70, 6.85, 4.33, P <0.05). The proportion of overweight and obesity in after school ES group decreased significantly from 19.5% to 12.3% ( χ 2=4.35, P <0.05). Compared with the control group, the scores of 50 meter running [(10.00±1.06, 10.21±0.83)s], 1 minute sit up [(33.25±8.24, 30.76±9.34)times], sitting and flexion [(14.53±7.50, 8.59±6.32)cm], 1 minute rope skipping [(125.01±30.50, 115.97±32.09)times], eyes closed and single legged standing [(30.00±34.72, 25.72±23.82)s], selective response time [(635.66±91.72, 652.79±120.42)ms] and VO 2max [(45.31± 1.02 , 43.67±0.85)mL/(kg〖 ·min)] in the after school ES group were significantly improved, with statistical significance ( F= 5.32 , 443.14, 97.23, 814.07, 36.49, 6.11, 396.91, P <0.05). Conclusions After school ES can improve body shape of primary school students, reduce the risk of overweight and obesity and enhance physical fitness. It is recommended that schools should appropriately increase after school ES to promote physical fitness of students.

Objective To explore the efficacy and safety of traditional Chinese medicine(TCM) combined with chemotherapy in the prevention and treatment of postoperative recurrence and metastasis of locally advanced gastric cancer (LAGC) by meta-analysis. Moreover, we evaluated the efficacy of TCM on the quality of life, immune indexes, and toxic and side effects during adjuvant chemotherapy. Methods The CNKI, Wanfang, PubMed, and other databases were searched by computer. Randomized controlled trials (RCTs) were searched. After literature screening and data extraction, Review Manager 5.3 software provided by Cochrane was used for meta-analysis. Results A total of 18 RCTs were included. Compared with chemotherapy alone, TCM combined with chemotherapy could improve the KPS score and CD3⁺ and CD4⁺/CD8⁺ index levels. The incidence rates of postoperative leucopenia, hemoglobin reduction, thrombocytopenia, nausea and vomiting, diarrhea, and neurotoxicity were reduced. In terms of postoperative QLQ-C30 score, abnormal liver function, and abnormal renal function, the incidence of TCM combined chemotherapy was similar to that of chemotherapy alone, with no statistical difference. Compared with chemotherapy alone, TCM combined chemotherapy could reduce the 1-, 2-, 3-, and 5-year cumulative recurrence and metastasis rates and prolong the disease-free survival time. Conclusion Compared with chemotherapy alone in adjuvant chemotherapy, TCM combined chemotherapy could improve the immune level and KPS score of LACC patients after surgery, reduce the incidence of adverse reactions, as well as reduce the recurrence and metastasis rate of LAGC after surgery and DFS could be improved.
