BACKGROUNDType 2 diabetes (T2DM) is one of the major metabolic diseases and poses a serious challenge to human life and global economic development. Jinqi Jiangtang Tablets (JQJT) is effective in ameliorating the effects of T2DM, but the mechanism of JQJT is unclear.PURPOSEThis study integrated metabolomics and transcriptomics to reveal the mechanism by which JQJT improves T2DM.METHODSThe T2DM mouse model was established, and the effects of JQJT on improving T2DM were evaluated by determining the levels of blood lipids, fasting blood glucose (FBG), insulin metabolism and hepatic lipid accumulation in mice after JQJT administration for 8 weeks. Serum metabolites were detected using ultra-performance liquid chromatography/quadrupole time-of-flight-tandem mass spectrometry (UPLC-Q-TOF-MS) technology, and mouse liver differential genes were detected using transcriptomic technology. Correlation analysis was used to extract metabolites and RNA with correlations, and potential pathways were enriched and constructed using the common pathway analysis function of MetaboAnalyst 5.0. Finally, the expression of key target proteins and genes was verified by Western blot (WB) and Polymerase Chain Reaction (PCR) to further elucidate the mechanism by which JQJT improves T2DM.RESULTSJQJT reduced FBG and lipid levels, improved insulin resistance (IR) and hepatic lipoatrophy in mice. A total of 35 differentially abundant metabolites were identified by metabolomics, and 328 differential genes were detected by transcriptomics. The integrated metabolomics and transcriptomics results suggested that JQJT may ameliorate T2DM mainly by regulating glucose and lipid metabolic pathways. WB and PCR results showed that JQJT regulates the insulin signaling pathway, involved in fatty acid metabolism, glycogen synthesis and catabolism.CONCLUSIONSJQJT improved IR in T2DM mice by regulating the insulin signaling pathway, improving glycogen synthesis and glycolysis, and increasing hepatic triglyceride and fatty acid metabolism.

Regulatory patterns of Chinese patent medicine for lipid metabolism disorders in patients with type 2 diabetes mellitus complicated by ischemic stroke: A systematic review and network meta-analysis

Background:To investigate the regulatory patterns of Chinese patent medicine (CPM) interventions on lipid metabolism disorders in patients with type 2 diabetes mellitus (T2DM) complicated by ischemic stroke.Methods:Two researchers independently searched 8 major databases and created a comprehensive database containing all randomized controlled trials (RCTs) that investigated the application of “blood-activating and stasis-removing” CPM in the treatment of stroke combined with T2DM until October 1, 2022. The collected data were compiled and organized in Excel. Quality assessment was performed using the Cochrane 5.3 bias risk assessment tool, and the network meta-analysis was conducted using R software.Results:A total of 12 articles were included in the final analysis, covering 4 types of CPM: Naoxintong Capsules (NXT), Tongmai Jiangtang Capsules, Tongxinluo Capsules (TXL), and Yindan Xinnaotong Soft Capsules. Among these, CPM formulations containing herbs with blood-activating and stasis-removing properties were the most commonly used. The results of the network meta-analysis are as follows: (1) the combination of 3 CPM formulations showed superior efficacy in improving total cholesterol levels compared to conventional Western medicine treatment (CT). In particular, Yindan Xinnaotong Soft Capsules + CT (surface under the cumulative ranking curve [SUCRA] = 97.24%) demonstrated the highest efficacy, followed by NXT + CT (SUCRA = 66.23%), and then TXL + CT (SUCRA = 55.16%). (2) TXL + CT treatment exhibited the most promising efficacy in improving triglyceride levels (P < .05), while the effects of the other 3 CPM formulations were not statistically significant. (3) In terms of improving low-density lipoprotein levels, NXT + CT (SUCRA = 82.27%) showed better efficacy than TXL + CT (SUCRA = 73.99%), while the effects of the other 2 CPM formulations were not statistically significant. (4) The combination of CPM formulations and CT resulted in a lower incidence of adverse reactions compared to CT (P < .05).Conclusion:The treatment of patients with T2DM complicated by ischemic stroke commonly involved the use of “blood-activating and stasis-removing” herbal medicines. These herbal medicines have shown effectiveness in regulating patients’ blood lipid levels. However, it is crucial to acknowledge that the analysis was influenced by variations in the number and quality of RCTs involving different CPM formulations. Therefore, additional validation through large-scale, high-quality RCT studies is required.

OBJECTIVETo observe the effect of Danzhi Jiangtang capsule (DJC) on the clinical indexes and vascular endothelial function indexes in patients with impaired glucose tolerance (IGT).METHODSA total of 106 patients were enrolled and randomly assigned to the treatment group and control group following a four-week washout period. The patients in the control group received a general lifestyle intervention, while those in the treatment group received DJC (2.0 g 3× a day) in conjunction with the intervention given to the control group patients. The physiological and biochemical levels, vascular endothelial function indices, and traditional Chinese medicine (TCM) syndrome ratings of the patients in the two groups were compared after 12 weeks of therapy.RESULTSIn the control group, the diastolic blood pressure (DBP) was significantly improved compared with those before treatment (83.31 ± 6.47 vs. 79.21 ± 6.17, p < .01) (CI: 1.45, 6.73; Cohen's d: 10.51), as was the case with the nitric oxide (NO) levels and TCM syndrome points (35.71 ± 4.58 vs. 43.96 ± 5.17, 9.57 ± 2.63 vs. 5.38 ± 1.79, p < .001) (CI: -10.28, -6.24; 3.12, 5.18; Cohen's d: 0.90). In the treatment group, the levels of fasting blood glucose, endothelin and vascular endothelial growth factor were significantly improved compared with control group (4.92 ± 0.21 vs. 5.59 ± 0.31, 59.37 ± 13.25 vs. 72.13 ± 12.37, 19.25 ± 2.80 vs. 26.76 ± 1.88, p < .001) (CI: 0.55, 0.78; 7.40, 18.13; 6.52, 8.50; Cohen's d: 4.94, 0.41, 1.32), as was the case with 2-h post-load plasma glucose and total cholesterol (TC) (8.33 ± 0.62 vs. 8.89 ± 1.55, 4.61 ± 1.05 vs. 5.22 ± 1.12, p < .05) (CI: 0.07, 1.07; 0.15, 1.06; Cohen's d: 0.40, 0.51).CONCLUSIONSTreatment with DJC could significantly improve the physiological and biochemical indicators, vascular endothelial function, and TCM syndrome points of IGT patients, indicating that DJC could be a potential drug to treat patients with IGT of Qi-Yin deficiency type.
