Objective To understand the learning motivation and innovation ability of eight-year program medical students in military Academy.Methods 57 students of six,eight grade of a military medical 8-year program were selected as the research object,among whom,there were 56 effective subjects (six grade 25,eight grade 31).The learning motivation scale,Williams' innovation ability scale and self-compiled questionnaire were used and in the form of questionnaire the students' learning motivation and innovation ability were analyzed.Results Among the medical students of eight-year program,the number of the low level of learning motivation was 7(12.5％),the number of medium was 43 (76.8％),the number of higher was 6(10.7％);Innovation ability overall score was (68.48 ± 5.466),four dimensions score of imagination,curiosity,adventure and challenge did not have statistical significance (F=2.254,P=2.254).The curious dimension score of grade six [(71.05 ± 8.035)] was higher than grade eight [(66.97 ± 6.585)],and there was statistical difference (t=2.086,P=0.042).Most of the students just had long-term goals for the future planning (35,62.5％).There were 27 (48.2％) students expecting good grades and 21(37.5％) expecting excellent grades.The number of the students who thought their innovation ability was higher was 28 (50.0％) and who thought their innovation ability was general was 27(48.2％).There were 82.1％ students whose motivation for an examination was mainly to improve their own quality,67.9％ of the students for contributing to the country.Conclusion The level of learning motivation and innovation ability of eight-year program medical students in military academy are more appropriate,but their innovation ability level is not ideal.The teaching reform should be deepened to further improve the students' learning motivation and innovation ability level.

Hepatic encephalopathy (HE) is caused by severe liver disease or portal shunt. Metabolic disorders and central nervous system dysfunctions are the main symptoms of this syndrome. Ammonia is considered to play a central role in the pathogenesis of HE. Helicobacter pylori (H. pylori) have been suggested as a possible source of ammonia production because of its high urease content. However, the relationship between H.pylori and blood ammonia and HE, as well as the therapeutic effect of H.pylori eradication on HE, is inconclusive, and the results are full of contradictions. The aim of this review is to summarize current knowledge on the association of H. pylori with HE and to address the question of whether H. pylori eradication may be beneficial in the management of HE.

Objective To evaluate the effect of mefformin on the human keratinocyte line HaCaT,and to explore its molecular mechanism.Methods HaCaT cells were divided into several groups to be treated with mefformin at different concentrations of 1,2,5,10,20,50 mmol/L for 24,48 and 72 hours.Cell counting kit-8 (CCK-8) assay was performed to evaluate the effect of metformin on the survival rate of HaCaT cells.After 48-hour treatment with metformin at concentrations of 0 (control group),0.5,1,2,5,10 mmol/L,flow cytometry was conducted to evaluate the effect of metformin on cell cycle and apoptosis.Western blot analysis was performed to determine the expression of cell proliferation-and differentiation-related proteins (keratin-16 [K16],K17,K1,involucrin),apoptosis-related proteins (Bax,Bcl-2) and AKT/mTOR/STAT3 pathway proteins.Enzyme-linked immunosorbent assay (ELISA) was conducted to detect the levels of interleukin (IL)-8,tumor necrosis factor (TNF)-α and IL-23 (inflammatory factors) in the culture supernatant of HaCaT cells.Statistical analysis was carried out with SPSS19.0 software using one-way analysis of variance for comparison of the above indices among the 0.5-,1-,2-,5-,10-mmol/L metformin groups and control group,repeated measures analysis of variance for comparisons among different time points or different metformin groups,least significant difference (LSD)-t test for multiple comparisons.Results CCK-8 assay showed that mefformin had inhibitory effects on the proliferation of HaCaT cells (F =116.87,P ＜ 0.05),and the cell survival rates gradually decreased along with the increase in the concentrations of mefformin.After 48-hour treatment with mefformin at concentrations of 0,0.5,1,2,5,10mmol/L,the proportion of HaCaT cells in G2/M phase gradually increased (5.55％ ± 1.03％,6.37％ ±0.93％,8.57％ ± 1.18％,10.05％ ± 0.60％,10.76％ ± 0.87％,13.63％ ± 1.41％,respectively,F =24.98,P ＜0.05),and the early apoptosis rate also gradually increased (0.78％ ± 0.71％,19.18％ ± 1.41％,25.67％ ±1.34％,28.45％ ± 0.92％,34.97％ ± 2.12％,40.41％ ± 1.49％,respectively,F =296.08,P ＜ 0.05).Along with the increase in the concentrations of metformin,there were increasing trends in the expression of K1 and the pro-apoptotic protein Bax (F =8.86,5.38 respectively,both P ＜ 0.05),while there were decreasing trends in the expression of K16,K17 and the apoptotic protein Bcl-2 (F =8.02,4.82,12.10 respectively,all P ＜ 0.05).There was no significant difference in the expression of involucrin among different metformin groups (F =0.57,P ＞ 0.05).After 48-hour treatment with mefformin at different concentrations,the levels of IL-8 and TNF-α in HaCaT cells significantly decreased (F =33.89,14.99 respectively,both P ＜0.05),while there was no significant change in the IL-23 level (F =2.12,P ＞ 0.05).Along with the increase in the concentrations of metformin,the expression of p-AKT,p-mTOR and p-STAT3 significantly decreased (F =11.38,0.35,4.38 respectively,all P ＜ 0.05),but there were no significant changes in the protein expression of AKT,mTOR and STAT3 (F =0.66,0.35,4.24 respectively,all P ＞ 0.05).Conclusion Metformin can inhibit the proliferation,promote the differentiation and apoptosis of HaCaT cells,and inhibit the secretion of inflammatory factors by regulating the AKT/mTOR/STAT3 signaling pathway.

The traditional Chinese medicine （TCM） myocardial infarction （MI） unit is a standardized， regulated， and continuous integrated care unit guided by TCM theory and built upon existing chest pain centers or emergency care units. This unit emphasizes multidisciplinary collaboration and forms a restructured clinical entity without altering current departmental settings， offering comprehensive diagnostic and therapeutic services with full participation of TCM in the treatment of MI. Its core medical model is patient-centered and disease-focused， providing horizontally integrated TCM-based care across multiple specialties and vertically constructing a full-cycle treatment unit for MI， delivering prevention， treatment， and rehabilitation during the acute， stable， and recovery phases. Additionally， the unit establishes a TCM-featured education and prevention mechanism for MI to guide patients in proactive health management， reduce the incidence of myocardial infarction， and improve quality of life.
