ObjectiveTo investigate medical students’ understanding of the essence of “red doctor spirit， characterized by political firmness， technical excellence， selfless dedication， healing the wounded and rescuing the dying， working hard， and daring to innovate，” their identification with the community connotations embodied in “red doctor spirit，” and the main issues existing in the process of “red doctor spirit” strengthening medical students’ sense of community for the Chinese nation， therefore providing references for cultivating medical talents with a cohesive sense of community for the Chinese nation. MethodsA self-designed and validated Questionnaire on the Cognition of Red Doctor Spirit in Strengthening Medical Students’ Sense of Community for the Chinese Nation was employed， and students from four grades and multiple majors at Xinjiang Medical University were selected as the research subjects. ResultsRegarding the understanding of “red doctor spirit，” no differences were found among medical students of different grades or political affiliations （P>0.05）， while differences were observed based on gender and major （P<0.05）. In terms of identification with community connotations embodied in “red doctor spirit，” no differences were noted among students of different grades， political affiliations， genders， or majors （P>0.05）. The lack of practical education was identified as the primary issue affecting “red doctor spirit” in strengthening medical students’ sense of community for the Chinese nation. ConclusionMedical colleges and universities should enhance the concept of “red doctor spirit” in strengthening medical students’ sense of community for the Chinese nation， explore its collaborative education model， strengthen its practical activities， and optimize the campus cultural environment， thereby fully leveraging the role of the “red doctor spirit” in forging a sense of community for the Chinese nation among medical students.

Objective To comfirm the anti-fibrotic effect of spironolactone and investigate the influence of spironolactone on concentration of angiotensinⅡ(AngⅡ) in rat hepatic fibrosis. Methods Ninety male Sprague-Dawly rats were randomly divided into three groups: control group (8 rats, subcutaneous injection of pure peanut oil, normal diet), model group (42 rats, subcutaneous injection of 40% CCl 4, 0.3 mL/100 g, twice a week, high cholesterol and low protein diet, 5% alcohol as the drink), and spironolactone group (40 rats, same dosage of CCl 4, high cholesterol and low protein diet, gastropufusion of spironolactone at the dose of 100 mg?kg -1?d -1). The animals were sacrificed at 2, 4, 6 and 8 weeks of administration. AngⅡ was assayed by radioimmunoassay. The liver tissues were stained, coded and examined. Results ① The general conditions of the rats of spironolactone group were better than those of the model group. The degree of fibrosis and the area of collagen in the liver of spironolactone group were less than those of the model group after the 4th week (P
