Front Pharmacol 2023; 14:1253572. [PMID: 37849730 PMCID: PMC10578493 DOI: 10.3389/fphar.2023.1253572] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 09/18/2023] [Indexed: 10/19/2023] Open
Abstract
Background: Diabetic cardiomyopathy (DCM) is a severe complication of diabetes that can diminish the quality of life in patients and is a leading cause of death. Research has demonstrated the effectiveness of Traditional Chinese Medicine (TCM) in reducing blood sugar levels and protecting cardiovascular function in both animal models and clinical research studies. Nevertheless, the efficacy of TCM in animal models of DCM has not been analyzed systematically. Method: We searched the following electronic bibliographic databases: Web of Science, PubMed, Cochrane Library, and CNKI(China National Knowledge Infrastructure). Studies that reported the efficacy of TCM in animals with DCM were included. The literature search was conducted using the terms. The data will be restricted from the year 2013 to 24 April 2023, 24 studies were included in the meta-analysis. Result: A total of 24 Traditional Chinese Medicine interventions and 2157 animals met the inclusion criteria. The pooled data revealed that TCM interventions resulted in significant improvements in body weight (BW), heart weight (HW) to body weight ratio (HW/BW), triglyceride (TG) and cholesterol (TC) levels, ejection fraction (EF), fractional shortening (FS) and E/A ratio. Subgroup analysis and meta-regression revealed that the type of TCM, duration of intervention, method of modeling, and animal species were potential sources of heterogeneity. Conclusion: TCM interventions were associated with significant improvements in body weight, heart weight to body weight ratio, triglyceride and cholesterol levels, left ventricular internal dimension in systole, ejection fraction, fractional shortening and E/A ratio. The heterogeneity in the results was found to be potentially due to the type of TCM, duration of intervention, method of modeling, and animal species, as shown in subgroup analysis and meta-regression. Systematic Review Registration: identifier CRD42023402908.

Yiqi Huoxue Recipe Regulates Autophagy through Degradation of Advanced Glycation End Products via mTOR/S6K1/LC3 Pathway in Diabetic Nephropathy. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:9942678. [PMID: 34408785 PMCID: PMC8367537 DOI: 10.1155/2021/9942678] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Revised: 06/28/2021] [Accepted: 07/22/2021] [Indexed: 11/30/2022]
Abstract
Background Yiqi Huoxue recipe can delay the progression of diabetic nephropathy, but its treatment mechanism is still unclear. We aimed to explore the effects of Yiqi Huoxue recipe on autophagy in diabetic nephropathy and its underlying mechanism. Methods All rats were randomly divided into seven groups. The body weight, kidney weight, blood glucose, glycated hemoglobin, urine protein, urine microprotein, creatinine, urea nitrogen, triglyceride, and lipoprotein were analyzed. HE, Masson, and periodic acid-Schiff staining were used to detect the severity of pathological changes in kidneys. The level of advanced glycation end products was assessed by the ELISA. Immunofluorescence staining was performed to check the expressions of podocin and nephrin. The expression levels of mTOR/S6K1/LC3 pathway-related proteins and mRNA were detected by qRT-PCR and western blotting. Results Yiqi Huoxue recipe significantly elevated body weight and significantly decreased kidney weight and kidney index. Yiqi Huoxue recipe significantly affected the levels of biochemical indicators in diabetic nephropathy and showed a regulatory effect on kidney damage and lipid metabolism disorders. ELISA showed that Yiqi Huoxue recipe significantly reduced the level of advanced glycation end products. The expressions of nephrin and podocin increased significantly, depending on the dosage of Yiqi Huoxue recipe. Additionally, Yiqi Huoxue recipe regulated the expression levels of p-AKT, mTOR, S6K1, and LC3. Conclusion Yiqi Huoxue recipe regulates podocyte autophagy to promote the degradation of advanced glycation end products through mTOR/S6K1/LC3 pathway. It has a certain guiding significance for the diagnosis and treatment of diabetic nephropathy.
