This paper aimed at investigating the effects of Xinfukang Oral Liquid on mitochondrial proteomic alterations in rats with heart failure after myocardial infarction and exploring its possible mechanisms. Heart failure models were established by ligating the left anterior descending coronary artery of SD rats. Rats were randomly divided into sham group, model group, Xinfukang group. 8 weeks after drug intervention, the mitochondrial proteomic alterations of myocardial tissue were detected by two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) . Furthermore, expression levels of part of the differently expressed proteins were verified by western blot. Compared with model group, 20 differentially expressed protein spots were detected in Xinfukang group, 13 of which showed increased protein expression and 7 decreased; 13 differentially expressed protein spots were successfully identified by MALDI-TOF-MS. Bioinformatics analysis showed that these differential proteins were mainly associated with energy metabolism, stress reaction, oxidative damage, cyto-skeleton, cell differentiation and proliferation. Western blot results showed that the expression of Stress-70 protein and Nucleophosmin increased and the expression of ATP-αdecreased in model group. The expression of Stress-70 protein and Nucleophosmin decreased and the expression of ATP-αincreased in Xinfukang group, which shows the same results in proteomics. Xinfukang Oral Liquid can partly adjust proteomic alterations of myocardial mitochondrial in HF rats, and its intervention mechanism may involve improving energy metabolism, reliving stress reaction and oxidative damage, as well as regulating cell differentiation and proliferation. The results of comparative proteomic analysis performed by using2-DE and MALDI-TOF-MS are acurate, stable and reliable.

Objective: To investigate the effects of Trimetazidine on mitochondrial proteomic alterations in heart failure rats with qi- deficiency and blood- stasis syndrome after myocardial infarction. Methods: Heart failure models were established by ligating the left anterior descending coronary artery of SD rats. Rats were randomly divided into sham group, model group, Trimetazidine group. 8 weeks after drug intervention, the mitochondrial proteomic alterations of myocardial tissue were detected by two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption/ ionization time- of- flight mass spectrometry (MALDI- TOF- MS). Furthermore, expression levels of part of the differentially expressed proteins were verified by western blot. Results: Compared with model group, 18 differentially expressed protein spots were detected in Trimetazidine group, 10 of which were successfully identified by MALDI-TOFMS. Bioinformatics analysis showed that these differential proteins were mainly associated with energy metabolism, stress reaction, oxidative damage, cyto-skeleton, cell differentiation and proliferation. Western blot results showed that the expression of Stress-70 protein and Nucleophosmin increased and the expression of ATP-αdecreased in model group. The expression of Stress- 70 protein and Nucleophosmin decreased and the expression of ATP- αincreased in Trimetazidine group, which showed the same results in proteomics. Conclusion: Trimetazidine can partly adjust proteomic alterations of myocardial mitochondrial in HF rats with qi-deficiency and blood-stasis syndrome, and its intervention mechanism may involve improving energy metabolism, relieving stress reaction and oxidative damage, as well as regulating cell differentiation and proliferation. The results of comparative proteomic analysis performed by using 2-DE and MALDI-TOF-MS are accurate, stable and reliable.

Objective:Applying bibliometrics to analyze the research history, hotspots and trends of Traditional Chinese Medicine (TCM) interventions in edema-related diseases, and to provide reference for the revision of diagnostic and therapeutic criteria for edema in TCM.Methods:The literature about edema treated with TCM was retrieved from CNKI, Wanfang, VIP, CBM from 1 st. Jan 1995 to 25 th. May 2022. CiteSpace and VOSviewer softwares were used to draw the knowledge map, and analyze the co-occurrence relationship and clustering characteristics of the institution, author, keywords and mechanism hotspots. Results:Totally 3 198 articles were included. The annual number of documents issued generally shows a spiral rise trend. Liaoning University of Chinese Medicine published the most articles. Core authors published the most articles were Sun Wei (13 articles); the team with the highest cooperation intensity was Yang Hongtao's team; keywords formed 7 clusters. Hotspot mechanisms included metabolic disorders, immune balance, anti-inflammation, calcium and phosphorus metabolism. Keywords in the past 7 years were membranous nephropathy, chronic heart failure, diabetes, lymphedema etc.Conclusions:The attention paid to the intervention of TCM in the field of edema is generally on the rise, and has decreased in the past two years. The research categories focus on the experience of famous doctors, clinical trials, and mechanistic studies, and nephropathy-related edema has been the focus of research; diabetic nephropathy, chronic heart failure, metabolomics, and immunotherapy are expected to be the focus of attention in the next stage.

Objective:To analyze the efficacy evaluation criteria of the existing TCM treatment for edema RCT research, and to provide reference for the construction of unified standards.Methods:The batabases CNKI, WanFang Data, VIP, CBM, Pubmed and Web of Science were retrieved. The randomized controlled trials for the treatment of edema of TCM research, from September 1, 1993 to July 31, 2022, were screened and included. The content of efficacy evaluation, performed statistics on evaluation standard, the curative effect evaluation indexes, as well as standard composition, usage were extracted. We analyzed the characteristics, application and problems of the existing efficacy evaluation criterion.Results:A total of 123 Chinese articles were included. The included literature involved nephrogenic edema, cardiogenic edema, idiopathic edema, apoplexy limb edema and other edema. In recent years, randomized controlled trials on the treatment of edema by TCM have mainly used four efficacy evaluation criteria. Of which the Guidelines for Clinical Research on New Chinese Medicines (Trial) in 2002 had the highest utilization rate of 29.27%. Secondly, the utilization rate of Standard for Diagnosis and Curative Effect of TCM Diseases and Syndromes was 21.14%. The rest of the criteria were used by less than 6%. While 39.02% of the literature did not use the standards or used self-designed standards. Among the composition of efficacy evaluation indices, the application rate of TCM syndrome or symptom efficacy index was the highest (91.87%), the utilization rate of the Minnesota Living with Heart Failure Questionnaire Indicators was only 4.88%; biochemical tests accounted for a large proportion of Western medical indicators, while the measurement of edema severity was rarely applied. Conclusions:At present, the evaluation criteria of edema curative effect are diversified and insufficiently popularized, which need to be further screened and improved. It is suggested to construct a TCM edema efficacy evaluation model based on the characteristics of edema syndrome, comprehensively evaluate the efficacy from multiple dimensions such as TCM syndromes, western medicine indicators, and quality of life, and improve the scientific indicators.
