Objective: To explore mental health status of vocational college students and its association with physical exercise and exercise motivation, so as to provide data support for the promotion of physical exercise, exercise motivation theory and the protection of mental health among vocational college students. Methods: From June 2 to July 2, 2023, a convenience sampling method was used to select 1 763 college students from three vocational colleges in Sichuan, Chongqing, and Guizhou for the survey. Physical Activity Rating Scale (PARS-3), Motives for Physical Activities Measure-Revised (MPAM-R), Patient Health Questionnaire-9 (PHQ-9) and Flourishing Scale (FS) were used to assess physical exercise, exercise motivation, depressive symptoms and flourishing levels of vocational college students. Multiple linear regression analysis was conducted to examine the relationship between physical exercise, exercise motivation, depression as the negative indicator of mental health and flourishing as the positive indicator of mental health. Results: There were negative correlations between physical exercise, exercise motivation and their five factors with depression scores among vocational college students ( r=-0.162--0.133, P <0.01). Physical exercise, health motivation and pleasure motivation were positively correlated with flourishing and its eight factors among vocational college students ( r= 0.054 -0.099, P <0.05). Depression scores and flourishing scores varied significantly across students with different levels of physical exercise and exercise motivation ( F=11.18-15.69, 2.80-16.05, P <0.05). Multiple linear regression analysis indicated that physical exercise, health motivation, and total exercise motivation scores were negatively correlated with depressive symptoms ( β = -0.02 , -0.11, -0.35), and physical exercise, health motivation, pleasure motivation, and total exercise motivation scores were positively correlated with flourishing ( β =0.31, 0.32, 0.50, 0.30) ( P <0.05). Conclusions Physical exercise and exercise motivation are significantly associated with mental health of vocational college students. Enhancing physical exercise and increasing exercise motivation in aspects of health and pleasure can promote mental health of vocational college students.

OBJECTIVES: This study examined the associations between adverse childhood experiences (ACEs) and diabetes within a social-ecological framework, incorporating personal and environmental unfavorable conditions during childhood from family, school, and community contexts. METHODS: Data were obtained from the China Health and Retirement Longitudinal Study (2014 life history survey and 2015 survey), including 9,179 participants aged ≥45 years. ACEs were collected through self-report questionnaires, and participants were categorized based on the number of distinct ACEs experienced (0, 1, 2, 3, or ≥4 ACEs). Diabetes was defined by biomarkers, self-reported diagnosis, and treatment status. Logistic regression was conducted to explore the associations between ACEs and diabetes. Subgroup analyses were conducted by gender, age, and obesity status. RESULTS: Compared with participants without ACEs, those exposed to any ACE (odds ratio [OR], 1.19; 95% confidence interval [CI], 1.01 to 1.40), 3 ACEs (OR, 1.32; 95% CI, 1.07 to 1.62) and ≥4 ACEs (OR, 1.29; 95% CI, 1.07 to 1.56) had an increased risk of diabetes. For each additional ACE, the risk of diabetes increased by about 5%. Regarding the source of ACEs, those originating from the family (OR, 1.23; 95% CI, 1.08 to 1.41) were associated with diabetes. In terms of specific ACE types, family members with substance abuse (OR, 1.23; 95% CI, 1.01 to 1.52), emotional abuse (OR, 1.28; 95% CI, 1.12 to 1.46), and poor parental relationship (OR, 1.25; 95% CI, 1.09 to 1.43) were associated with diabetes. CONCLUSIONS ACEs, particularly those originating from the family, were associated with diabetes. Interventions aimed at preventing and mitigating ACEs are essential for the early prevention of diabetes.

Objective:To verify the application value of team-based learning (TBL) joint case-based discussion (CBD) method applied in the course teaching of Introduction to General Practice.Methods:Students from two clinical oriented classes in the same grade were divided into the experimental group ( n=35) and the control group ( n=35).

SPSS 20.0 was used for frequency description and statistical test analysis. Non-normal distribution data were tested with Mann-Whitney U test. Results:After the teaching, the average rank of multiple-choice questions (35.28) and analytic questions (42.24) in the experimental group were significantly higher than those of the control group (32.68 and 25.52, respectively, P<0.05). Conclusion:The TBL joint CBD method applied in the course of general practice helps to improve students' test achievement, enhance their overall quality, and lay a foundation for training comprehensive competencies of general practitioners.

By bioinformatics analysis, a putative keratinase gene gm2886 (Accession number: KY368946) was discovered in the genome of a feather-degrading strain, Streptomyces albidoflavus Fea-10. gm2886 was ligated into integrative Escherichia coli-Streptomyces shuttle vector pSET152 under the promoter PermE and added with C-terminal His-tag. The expression vector was transformed into Streptomyces pactum ACT12 by conjugal transfer and the recombinant protein GM2886-His6 was detected in fermentation broth. GM2886-His6 was purified and characterized. Its size was nearly 36 kDa. GM2886-His6 showed proteolytic activity towards a variety of substrates and could even degrade insoluble substrates, such as azure keratin and chicken feathers. The optimal pH and temperature of GM2886-His6 for proteolysis of casein was pH 10.0 and 50 ℃, respectively. The enzyme activity was inhibited by PMSF, but not EDTA, indicating that GM2886-His6 was a serine proteinase. Our results laid the foundation for the research of the molecular biological mechanism on feather-degrading and for the further utilization of Fea-10.

Objective: To investigate the effect of AKT1 deSUMOylation induced by Ubc9 silencing on the proliferation and metastasis of hepatocellular carcinoma (HCC) cells. Methods: The Ubc9 gene was silenced using RNA interference, and the expression levels of Ubc9, SUMO1 and AKT1 protein were detected by Western blot. Cell proliferation and cell cycle was analyzed by MTT and flow cytometry. Wound healing and transwell assays were used to detect the cell migration ability. Furthermore, the xenograft model was established, and tumor growth curves were drawn. The in situ apoptotic rates was measured using TUNEL Apoptosis Assay. The expression of proliferating cell nuclear antigen (PCNA), matrix metalloproteinase (MMP)-2 and MMP-9 were evaluated by immunohistochemical staining. Results: Knockdown of Ubc9 gene significantly decreased the protein expression levels of Ubc9, conjugated SUMO1, free SUMO1 and AKT1 in HCC cells (P<0.05 for all). In control, siR-neg and siR-Ubc9 groups, the cell proliferation indexes were 53.19%, 54.25% and 39.17%, respectively. Moreover, cell migration distance and migrating cells per low power field for all these three groups were (59.47±4.66) μm and 89.44±8.36, (56.56±5.37) μm and 93.84±8.79, as well as (34.57±6.61) μm and 41.67±5.39, respectively. In the xenograft model, the weights of subcutaneous tumors for these three groups were (3.78±0.69) g, (3.72±0.72) g and (2.09±0.61) g, respectively. The corresponding apoptotic cell rates were (7.79±2.21)%, (6.45±2.48)% and (33.59±5.44)%, respectively. The expression levels of PCNA, MMP-2 and MMP-9 protein were significantly decreased in siR-Ubc9 group (P<0.05). Conclusions Ubc9 silencing in HCC cells induces AKT1 deSUMOylation, and then inhibits the proliferation and metastasis. These results provide a new therapeutic strategy for liver cancer in the future.

OBJECTIVE: To explore the association of mental health,job burnout and mental fatigue in mental workers.METHODS: A total of 276 mental workers in 11 research institutes in Ningxia were selected as research subjects by convenient sampling method. The questionnaire survey was carried out using the scales of Self-Reporting Inventory( SCL-90),Maslach Burnout Inventory-General Survey and Mental Fatigue subscale of Fatigue Scale-14 to investigate the workers' mental health,job burnout and mental fatigue. RESULTS: The scores of SCL-90 and job burnout in mental workers were( 142. 4 ± 42. 2) and( 41. 8 ± 10. 5). The medium( P25,P75) mental fatigue total score was [3. 0( 2. 0,4. 0) ].The correlation analysis showed that the total score of SCL-90 was positively correlated with that of mental fatigue and job burnout( P < 0. 01). The job burnout was the intermediate variable between mental fatigue and mental health( 43. 4% of the total effect). The dimension of low sense of accomplishment was the regulating variable. CONCLUSION: Job burnout plays an intermediate role between mental fatigue and mental health in mental workers. The low sense of accomplishment plays a regulatory role.

OBJECTIVETo explore the effects of electrical stimulation at acupoints in the distribution area of auricular vagus nerve combined with sound masking on auditory brainstem response (ABR) and contents of neurotransmitters of γ-aminobutyric acid (γ-GABA), 5-hydroxytryptamine (5-HT) and acetyl choline (Ach) in inferior colliculus of tinnitus rats.

METHODSTwenty-four male adult SD rats were randomized into a control group, a model group, a 7-d treatment group and a 15-d treatment group. Except the control group, rats in the remaining groups were treated with intraperitoneal injection of 10% salicylate sodium at a dose of 350 mg/kg to establish tinnitus model. Rats in the control group were treated with injection of 0.9% NaCl. Rats in the 7-d treatment group and 15-d treatment group were treated with electrical stimulation at "Shenmen (TF₄)" and "Yidan (CO₁₁)" in the distribution area of auricular vagus nerve combined with sound masking, once a day, for 7 days and 15 days. The SigGenRP software of TDT system was applied to provide voice for single ear and collect the signal, and the voice threshold of ABR was tested. The levels of γ-GABA, 5-HT and Ach in inferior colliculus of rats were detected by enzyme linked immunosorbent assay (ELISA) and compared.

RESULTSCompared with the model group, the threshold values of ABR in 12 kHz and 16 kHz voice stimulation in the 7-d treatment group were significantly lower all P < 0.05); the threshold values of ABR from 4 kHz to 28 kHz voice stimulation in the 15-d treatment group were signally reduced (P < 0.05, P < 0.01), which was more significant than those in the 7-d treatment group. The level of γ-GABA in the model group was significantly lower than that in the control group (P < 0.05), and that in the 15-d treatment group was apparently higher than that in the model group (P < 0.05). The level of 5-HT in the model group was markedly higher than that in the control group (P < 0.05), and that in the 7-d treatment group was lower than that in the model group (P < 0.05), while that in the 15-d treatment group was apparently higher than that in the model group (P < 0.05). The level of Ach in the model group was obviously; lower than that in the control group (P < 0.05), and that in the 7-d treatment group was higher than that in the model group (P < 0.05).

CONCLUSIONElectrical stimulation at auricular vagus nerve combined with sound masking) could regulate the threshold of ABR, especially in the 15-d treatment group. This may be ascribed to modulating the levels of neurotransmitter of γ-GABA, 5-HT and Ach in inferior colliculus.
