ABSTRACT
Objective:To evaluate the clinical efficacy rate, vascular endothelial relaxation factor NO and safety of five different Chinese patent medicines combined with western medicine in the treatment of coronary microvascular disease (CMVD).Methods:Randomized controlled trials (RCTs) of Shexiang Baoxin Pills, Tongxinluo Capsules, Compound Danshen Dripping Pills, Yindan Xinnaotong Soft Capsules, and Xinkeshu Tablets combined with conventional western medicine therapy in the treatment of CMVD were retrieved from China National Knowledge Infrastructure (CNKI), China Academic Journal Database (Wanfang Data), Chinese Science and Technology Journal Database (Chongqing VIP), China Biomedical Literature Service System (SinoMed), PubMed, Cochrance Library and Embase databases from the establishment of the database to June 2022. The literature was imported and screened by EndNote software, and the risk quality of literature bias was evaluated by Revman 5.4 software. StataSE16 (64-bit) software was used for reticular meta analysis to compare the differences in clinical efficacy and drug safety of five proprietary Chinese medicines combined with western medicine.Results:A total of 24 RCT studies were included, 24 of which were double-arm studies, and five kinds of proprietary Chinese medicine combined with western medicine were compared. The results of reticular meta analysis: in terms of improving the clinical effective rate, the order of the five proprietary Chinese medicine combination groups was as follows: Yindan Xinnaotong Soft Capsules group > Shexiang Baoxin Pills group > Tongxinluo Capsules group > Xinkeshu Tablets group > Compound Danshen Dripping Pills group. In terms of regulating vasodilation factor NO, the order of the four proprietary Chinese medicine combination groups is as follows: Yindan Xinnaotong Soft Capsules group > Compound Danshen Dripping Pills group > Tongxinluo Capsules group > Shexiang Baoxin Pills group. In terms of safety, there were 3 reports of adverse reactions in the research literature of the five proprietary Chinese medicines.Conclusions:The clinical efficacy rate of five kinds of proprietary Chinese medicine combined with western medicine routine regimen is better than that of western medicine routine regimen alone, and the combination group of four kinds of proprietary Chinese medicine is superior to western medicine in regulating vasodilation factor NO, and Yindan Xinnaotong Soft Capsules group is superior in clinical efficacy rate and regulation of vasodilation factor NO. However, the quality and samples of this study are different, and the comparison of the curative effect of the combined group of proprietary Chinese medicine still needs a large sample and high-quality RCT study to demonstrate.
ABSTRACT
Coronary heart disease （CHD） with atherosclerosis is a common chronic disease worldwide， and anxiety and depression are potential and crucial risk factors for adverse prognosis in CHD. Chaihu Longgu Mulitang （CLMT）， first mentioned in the Shang Han Lun （《伤寒论》）， is a classic prescription for treating Shaoyang diseases combined with disturbance of the mind and spirit， with the effects of harmonizing Shaoyang and calming the mind. Current research on mechanisms has shown that CLMT can play a role in CHD complicated with anxiety and depression through multiple pathways， including regulating related signaling pathways， inhibiting the expression of inflammatory factors， improving oxidative stress damage， modulating neurotransmitter levels， suppressing the hypothalamic-pituitary-adrenal axis， promoting mobilization of mesenchymal stem cells from the bone marrow， and inhibiting platelet activation. Clinical studies have demonstrated that CLMT significantly improves symptoms such as angina and insomnia caused by CHD complicated with anxiety and depression， effectively reduces negative emotions， improves traditional Chinese medicine （TCM） syndrome scores， and decreases levels of inflammatory factors. Furthermore， it has fewer adverse reactions and higher safety than conventional western medicine treatments. This article provides a review of the mechanisms and clinical studies of CLMT in the treatment of CHD complicated with anxiety and depression based on a comprehensive analysis of literature from the China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， PubMed， and other databases in the past 15 years， in order to provide references for further research on the use of CLMT in the management of CHD complicated with anxiety and depression.
ABSTRACT
Objective:To explore the association rules of personality traits and health-promoting lifestyle in patients with primary angle closure glaucoma, so as to provide advice for the synthetical treatment.Methods:From July to November 2021, a total of 117 primary angle closure glaucoma patients(acute patients n=89, chronic patients n=28) in ophthalmology department of five hospitals in Nanjing were investigated with type A behavior pattern scale, health-promoting lifestyle scale Ⅱ and general information questionnaire.Based on Weka 3.8.5, algorithm of Apriori was used to mine its association relationship. Results:(1) The total scores of type A behavior pattern scale for patients with acute and chronic types of primary angle closure glaucoma were (32.48±6.43) and (27.54±6.49) respectively.The total scores of health-promoting lifestyle scale Ⅱ were (101.69±11.83) and (97.79±7.78) respectively.(2) There were positive associations among patients with acute primary angle closure glaucoma, type A/A-personality (including impatience and hostility) and health-promoting lifestyle (including stress management disorder, interpersonal relationship management disorder, well sense of health responsibility and adequate dietary nutrition intake)(all support>0.1, confidence >0.6, lift >1.0). And patients with chronic primary angle closure glaucoma were associated with B/B-personality (including patience and mild), health-promoting lifestyle (including stress management disorder, interpersonal relationship management disorder, well sense of health responsibility and adequate dietary nutrition intake)(all support>0.1, confidence >0.6, lift >1.0).Conclusion:Primary angle closure glaucoma is strongly related with personality traits and health-promoting lifestyle.Its synthetical treatment plan should take both physical and mental measures, and classified health management for patients with different disease types.
ABSTRACT
Objective To understand the situation of college students' knowledge, attitude and practice (KAP) of innovation and entrepreneurship activities and analyze their influencing factors, in order to provide a scientific basis for further promotion of innovation and entrepreneurship activities. Methods A self-administered questionnaire survey using cluster sampling method was conducted among 850 undergraduates in a medical university in May, 2018. The demographic characteristics and questions pertaining to the KAP of innovation and entrepreneurship activities were collected, The weighted scores of KAP were calculated using the Delphi method. Chi-square test, multivariate logistic regression and linear regression analysis were used to analyze the data. Results A total of 850 questionnaires were sent out and 800 valid questionnaires were collected. The average scores and pass rates for the knowledge, attitude and practice of the 800 college students were (0.54 ±0.14), 38.1％; (0.56 ±0.23), 51.5％; and (0.37 ±0.19), 12.6％, respectively. Knowledge: the pass rate for the concepts related to innovation and entrepreneurship was 70.5％, and the pass rate for the policies related to innovation and entrepreneurship was 17.2％. The pass rate of senior students and excellent students were higher than those of junior students and students of lower academic competence (P=0.000, P=0.004). Attitudes: the pass rate for attitude towards the relationship between innovation and entrepreneurship and personal development was 63.6％, the pass rate for attitudes towards participation in innovation and entrepreneurship was 49.8％, and the pass rate for attitudes towards the school continuing to carry out innovation and entrepreneurship related activities was 23.8％. Practice:the pass rates for participation in scientific research and academic activities and social practice , voluntary cultivation of innovation ability and self-employment were 8.5％, 62.9％, 11.9％and 27.3％, respectively. The pass rate of senior grades was higher than that of junior grades (P=0.001). Scores for knowledge and those of attitude are positively correlated. Scores for practice and those of knowledge and attitude are positively correlated. Conclusion The higher pass rates for medical college students' attitude toward innovation and entrepreneurship activities as compared to those for knowledge and practice indicates high eagerness toward participation in innovation and entrepreneurship activities; a high rate knowledge is conducive to the cultivation of attitudes and the improvement of participation in activities . Therefore , it is necessary to strengthen the efforts in carrying out innovation and entrepreneurship activities , improve publicity and education, and promote the awareness-raising of innovation and entrepreneurship.
