Objective: To understand the awareness of chikungunya fever knowledge and its related factors among medical college students in Baise City, so as to provide a scientific basis to offer relevant courses and special education. Methods: From July to August 2025, 7 286 enrolled medical students were selected by a sampling method from a medical college in Baise City to participate in the questionnaire survey. The questionnaire covered epidemiological characteristics, clinical symptoms, and prevention/control knowledge of chikungunya fever. Statistical analyses including the Chi quare test and multivariate Logistic regression models were performed. Results: The overall awareness rate of chikungunya fever knowledge among the medical students was 18.89%. Among the knowledge items, the awareness rate of "the high incidence season" was the highest (84.05%), while that of "the infectious period" was the lowest (17.80%). Multivariate Logistic regression analysis showed that medical students with female (a OR= 1.37 , 95%CI =1.20- 1.57 ), the age for over 25 years old (a OR=1.76, 95%CI =1.05-2.93), whose father had a middle school educational level (a OR=1.18, 95%CI =1.05-1.31), and majored in preventive medicine (a OR=1.54, 95%CI =1.10-1.67) had relatively higher awareness rates of chikungunya fever knowledge (all P <0.05). In contrast, students of Zhuang ethnicity (a OR= 0.87 , 95%CI =0.76-0.98) and majoring in nursing (a OR=0.74, 95%CI =0.61-0.91) or pharmacy (a OR=0.70, 95%CI =0.52-0.95) had relatively lower awareness rates (all P <0.05). Conclusions The awareness rate of chikungunya fever related knowledge among medical college students in Baise City is relatively low. Schools should take targeted publicity measures to improve medical students awareness.

Objective:To retrieve and obtain relevant evidence of intra-abdominal pressure-oriented enteral nutrition assessment and management in patients with intra-abdominal hypertension, in order to provide evidence-based evidence for clinical medical staff to make enteral nutrition-related clinical decisions for patients with intra-abdominal hypertension.Methods:Systematic retrieval of Chinese National Knowledge Infrastructure, Wanfang, Chinese Biomedical Literature, UpToDate, PubMed, Cochrane Library, BMJ Best Practice and other English data, as well as domestic and foreign guidelines such as American Society for Parenteral and Enteral Nutrition, Scottish Intercollegiate Guidelines Network, etc. All evidence available on the Internet in both Chinese and English on intra-abdominal pressure-guided enteral nutrition strategies in adults with intra-abdominal hypertension, study types including clinical decision-making, systematic reviews/meta-analyses, evidence summaries, expert consensus, guidelines or related to the subject of this study closely related high-quality original research. The retrieval time was from the establishment of the database to November 2021. The literature evaluation tool was selected according to the research type. Two researchers trained in the evidence-based system independently evaluate the quality of the included literature, fully considering the clinical situation and expert opinions, and completed the evidence. Extracted and summarized.Results:Totally 13 articles were finally included, including 5 guidelines, 3 expert consensuses, 1 evidence summary and 4 original studies, and 29 evidence-based practice evidence of enteral nutrition in patients with intra-abdominal hypertension were collected, including the monitoring timing of enteral pressure, the pressure of enteral high pressure and the way of enteral nutrition, the pressure measurement of the abdominal cavity, the setting of abdominal pressure, the temperature conditions for early start of enteral nutrition, the selection of enteral pressure, the temperature setting of enteral nutrition nine aspects such as speed and regulation of internal nutrition and abdominal compartment syndrome prevention.Conclusions:This study summarizes the best evidence of intra-abdominal pressure management and enteral nutrition therapy in patients with intra-abdominal hypertension, and provides evidence-based basis for risk management, standardizing clinical practice, and ensuring treatment safety. In the stage of evidence transformation, clinical medical staff need to comprehensively weigh the benefits and risks of early enteral nutrition, and integrate evidence in combination with clinical practical application scenarios, so as to form a standardized early enteral nutrition management plan suitable for patients with intra-abdominal hypertension.

Objective To explore the influence of Yoga exercise on the work stress and coping styles of operating room nurses. Methods A total of 77 nurses were selected working in the operating room of our hospital,and all the nurses were randomly divided into observation group(38 cases)and the control group (39 cases). The nurses of observation group did Yoga exercise regularly,while the nurses of control group did not make any Yoga workout regularly. We used psychological stress scale( CPSS)to assess anxiety of two groups nurses before and after the intervention,and investigated every nurse's pressure coping style respectively before and after care. Results Pressure improvement mark in the observation group had been greatly improved after Yoga exercise intervention(16. 203 ± 4. 218),while it was(3. 127 ± 1. 037)in the control group with statistical significance( t = 3. 012,P < 0. 05);the improvement of anxiety in the observation group was significantly better than that of the control groups,the difference had statistical significance(P < 0. 05);the stress coping style of observation group were obvious improved after the intervention compared with that of the control group(P < 0. 05). Conclusions Yoga exercises can improve the working stress and coping operating room nurses effectively.

Obej ctive To investigate the role of metastasis associated protein 1(MTA1)in estrogen reg-ulated expression of matrix metalloproteinase -9(MMP-9)and tissue inhibitor of metalprotease -1(TIMP-1) in estrogen receptor( ER ) positive breast cancer cells .Methods MTA1 knockdown cell model was generated based on MCF-7breast cancer cell line by transfected with MTA 1-shRNA.The mRNA and protein level of MMP-9 and TIMP-1 in wild type MCF-7(MCF-7WT)and MCF-7MTA1-shRNA before and after 17β-estradiol ( E2) treatment were examined by Real -time PCR and Western blot respectively .Results The MTA1-shRNA showed maximally 84.9%suppression of MTA1 expression in MCF-7,suggesting a satisfied MTA 1 knockdown cell model was established for subsequent experiments .After treated with E2 for 48 h,MCF-7WT showed an incre-ment of 46%(P<0.05)and 37%(P<0.05)of the mRNA and protein level of MMP -9 and a decrement of 32.3%( P<0.05)and 18.2%(P<0.05)of TIMP-1;MCF-7MTA1-shRNA showed a decrement of 32.3%(P<0.05)and 18.2%(P<0.05)of mRNA and protein expression of MMP -9 respectively but no significant differ-ence in TIMP-1 comparing with MCF-7WT before treated with Estradiol.After E2 treatment,MCF-7MTA1-shRNA didn′t show significant change of MMP -9 except decrements of 32.3%(P<0.05)and 18.2%(P<0.05)in the mRNA and protein levels of TIMP -1.Conclusion MTA1 may be involved in the pathway by which estrogen regulated the expression of MMP -9 but not TIMP-1 in ER positive breast cancer cells .
