Objective To explore the prevention effectiveness of a mode,conducting targeted corrective training based on motor dysfunction detected by military joint function screening,on military training injuries in new recruits during recruit basic training in order to cope with the high incidence of military training injuries among them.Method A military personnel joint function screening was conducted on the new recruits in a training base of Joint Logistics Support Force.Based on the results of screening,the new recruits with a single action score of 1 and a total score of<10 were subjected and served as corrective training participants.Through cluster sampling,the new recruits were randomly divided into an experimental group(n=223)and a control group(n=223).The control group were trained according to the regular training plan,while the experimental group completed their designated training tasks and a 2-month corrective training for motor dysfunction at the same time.The entire corrective training process was carried out by our key personnel who had received relevant training.Medical records of the medical security department of the experimental unit were collected and evaluated for the injury situation.The score of joint function screening was analyzed using independent sample t test.The incidence of training injuries was analyzed using Chi-square test or Fisher's exact test.Result After corrective training,the score of joint function was higher in the experimental group than the score before training(15.12±2.13 vs 10.58±2.83),and the score was also higher than that of the control group(15.12±2.13 vs 14.19±1.97,P<0.05).During the recruit basic training period,the incidence of training injuries was notably lower in the experimental group than the control group(12.5％vs 34.5％,Chi-square=5.469,P=0.001).Only for those who were injured during the training,11 people(39.2％)in the experimental group scored less than 10,which was obviously lower than the 49 people(63.6％)in the control group(Chi-square=4.972,P=0.026).Conclusion Our mode,corrective training based on the results of military personnel joint function screening,can effectively reduce the incidence of military training injuries in new recruits during recruit basic training,and exerts a good preventive effect against military training injuries.

Objective To identify recruit movement dysfunction based on military joint function screening and assessment,implement targeted corrective training,explore the impact of this assessment-correction system on knowledge-attitude-belief-practice(KABP)related factors,and scientifically evaluate its efficacy in preventing recruit military training injuries within the knowledge-attitude-belief-practice theoretical framework.Methods A cluster randomized controlled trial was conducted at a recruit training base of the Joint Logistics Support Force from March to May 2025,enrolling 446 recruits.Participants were randomly assigned to an experimental group(n=223)or control group(n=223)using a random number table.The control group followed the routine training program,while the experimental group additionally received a 2-month targeted corrective training for movement dysfunction alongside the established training tasks.Knowledge-attitude-belief-practice questionnaires were administered to both groups at the initial,intermediate,and advanced stages of the corrective training.Univariate logistic regression was used to preliminarily screen KABP-related factors,and a multivariate logistic regression model was further constructed to analyze the role of KABP factors in the corrective training.Results The experimental group had a cumulative training injury incidence of 40 cases(17.9%),which was significantly lower than that of the control group(83 cases,37.2%;χ2=20.757,P<0.001).The experimental group showed varying degrees of improvement in knowledge,attitude and belief,and practice dimensions(P<0.05),while the control group exhibited no significant changes in the three KABP dimensions across the three surveys.Logistic regression analysis revealed:In the first round,total practice score was significantly negatively associated with training injury incidence rate(OR=0.863,95%CI:0.822～0.906,P<0.001),whereas knowledge and attitude-belief dimensions showed no significant association;In the second round,both total knowledge score(OR=0.925,95%CI:0.903～0.946,P<0.001)and total practice score(OR=0.906,95%CI:0.874～0.940,P<0.001)significantly reduced the risk of military training injuries,with attitude-belief dimension still showing no significant effect;In the third round,all three KABP dimensions were significantly negatively associated with military training injury incidence rate(knowledge:OR=0.905,95%CI:0.884～0.926,P<0.001;attitude and belief:OR=0.942,95%CI:0.899～0.988,P=0.013;behavior:OR=0.882,95%CI:0.841～0.924,P<0.001).Conclusion Joint function screening and corrective training can significantly reduce the incidence of recruit training injuries,primarily by optimizing knowledge mastery and movement behavior;belief cultivation,however,requires long-term practical accumulation.

Inulin has been used as a prebiotic to alleviate glucose and lipid metabolism disorders in mice and humans by modulating the gut microbiota. However, the mechanism underlying the alleviation of metabolic disorders by inulin through interactions between the gut microbiota and host cells is unclear. We use ob/ob mice as a model to study the effect of inulin on the cecal microbiota by 16S rRNA gene amplicon sequencing and its interaction with host cells by transcriptomics. The inulin-supplemented diet improved glucose and lipid metabolism disorder parameters in ob/ob mice, alleviating fat accumulation and glucose intolerance. The α diversity of gut microbial community of ob/ob mice was reduced after inulin treatment, while the β diversity tended to return to the level of wild type mice. Interestingly, Prevotellaceae UCG 001 (family Prevotellaceae) was obviously enriched after inulin treatment. A comparative analysis of the gene expression profile showed that the cecal transcriptome was changed in leptin gene deficiency mice, whereas the inulin-supplemented diet partially reversed the changes in leptin gene-related signaling pathways, especially AMPK signaling pathway, where the levels of gene expression became comparable to those in wild type mice. Further analysis indicated that Prevotellaceae UCG 001 was positively correlated with the AMPK signaling pathway, which was negatively correlated with markers of glycolipid metabolism disorders. Our results suggest that the inulin-supplemented diet alleviates glucose and lipid metabolism disorders by partially restoring leptin related pathways mediated by gut microbiota.

The change of subcellular localization of tumor-related proteins affects the protein structure and biological function, which is closely related to tumorigenesis, tumor progression and prognosis. Aberrant phosphorylation, acetylation and ubiquitination lead to the subcellular localization change of tumor-related proteins, subsequently disrupt the down-stream target gene expression and the related cell signal pathways, which is an important factor for tumorigenesis. The anti-cancer drugs targeting post-Translational protein modification can reverse the abnormal subcellular localization of tumor-related proteins, so as to suppress the migration of tumor cells, and induce the apoptosis of tumor cells. This paper reviews the recent studies regarding the effects of phosphorylation, acetylation and ubiquitination on subcellular localization of tumor-related proteins such as p53, p27 and forkhead box protein O1 (FOXO1), and summarizes the molecular mechanisms of subcellular localization change induced by anti-cancer drugs, furthermore discusses the great significance of protein subcellular localization in clinical tumor diagnosis and the pridiction of prognosis and the drug effect.

Objective To evaluate the efficacy and safety of two forms of preparations of dexamethasone palmitate in the treatment of rheumatoid arthritis (RA).Methods A multicenter,double-blind,randomized,parallel-group clinical trial was carried out according to good clinical practice (GCP).A total of 237cases of RA patients with mild to moderate knee swelling were randomly divided into the treatment group (n=118 ) or the control group (n=119) and were treated with two kinds of dexamethasone palmitate 8 mg injection respectively.The primary efficacy endpoints were the circumference of the knee joint at the upper and the lower edge after the intra-articular injection.The secondary efficacy endpoints were joint tenderness index and patients general assessment.The adveme events were recorded.Analysis of covariance,t test or Wilcoxon test,x2 test or Fisher exact test were used for statistical analysis.Results The upper edges of the treatment group and the control group after treatment were (37.2±3.3) cm and (36.4±3.9) cm respectively,and the lower edges of the two groups were (34.4±2.9) cm and (33.9±3.4) cm respectively.They were all significantly smaller than the edges before treatment [(38.1± 3.3) cm and (37.3±4.0) cm of the upper edges,(35.1±3.0)cm and (34.6±3.6) cm of the lower edges respectively ) (P＜0.O1)].After treatment,the joint tenderness index were improved (P＜0.01).A total ratio of great improvement and improvement of patients general assessment of the two group patients were 67.5％ (79/117) and 74.8％ (86/115) respectively.No statistical significant difference was found in all primary and secondary efficacy endpoints between the two groups (P＞0.05).During the clinical trial,the incidence of adverse events related to the treatment of two groups were 4.2％ and 6.8％,without any significant difference (P＞0.05).Conclusion New preparation of dexamethasone palmitate has the same efficacy and safety as the imported producted in the treatment of RA.The circumference of the knee joints at the upper and the lower edge may be used to assess the effects of intra-articular injections.
