Relevance of the pyroptosis-related inflammasome drug targets in the Chuanxiong to improve diabetic nephropathy.

BACKGROUND: A chronic inflammatory disease caused by disturbances in metabolism, diabetic nephropathy (DN) is a chronic inflammatory disease. Pyroptosis is a novel form of programmed cell death in many inflammation-related diseases, including DN. Therefore, pyroptosis could be a promising target for DN therapy. METHODS: To get the components and pharmacodynamic targets of Chuanxiong, we identified by searching TCMID, TCMSP, ETCM and HERB databases. Then, from the Molecular Signatures Database (MSigDB) and Gene Ontology (GO) database, pyroptosis genes were collected. Identification of critical genes in DN by bioinformatics analysis and then using the ConsensusClusterPlus package to divide the express data of diff genes into some subgroups with different levels of pyroptosis; the WGCNA machine algorithm was used to simulate the mechanism Chuanxiong improving DN. RESULTS: In this study, we found DHCR24, ANXA1, HMOX1, CDH13, ALDH1A1, LTF, CHI3L1, CACNB2, and MTHFD2 interacted with the diff genes of DN. We used GSE96804 as a validation set to evaluate the changes of APIP, CASP6, CHMP2B, CYCS, DPP8, and TP53 in four different cell proapoptotic states. WGCNA analysis showed that DHCR24, CHI3L1, and CACNB2 had significant changes in different cell proapoptotic levels. In the experimental stage, we also confirmed that the active ingredients of Chuanxiong could improve the inflammatory state and the levels of pyroptosis under high glucose. CONCLUSION: The improvement of DN by Chuanxiong is related to the change of pyroptosis.

Efficacy of liraglutide in patients with diabetic nephropathy: a meta-analysis of randomized controlled trials.

BACKGROUND: The efficacy of liraglutide to treat type 2 diabetic nephropathy (T2DN) remains controversial. Thus, we conducted this meta-analysis to systematically evaluate the clinical effect of liraglutide on T2DN patients. METHODS: Eight databases (PubMed, Web of Science, the Cochrane Library, EMBASE, Chinese National Knowledge Infrastructure (CNKI), Wanfang database, China Science and Technology Journal Database, and China Biology Medicine Database (CBM)) were searched for published articles to evaluate the clinical efficacy of liraglutide in subjects with T2DN. The Revman 5.3 and Stata 13 software were used for analyses and plotting. RESULTS: A total of 18 randomized controlled trials (RCTs) with 1580 diabetic nephropathy patients were screened. We found that the levels of UACR, Scr, Cysc were lower in the experimental group of T2DN patients treated with liraglutide than in the control group intervened without liraglutide. Liraglutide also reduced the levels of blood glucose (including FBG, PBG, and HbA1c), body mass index (BMI), and anti-inflammatory indicators (TNF-α, IL-6). However, there was no significant difference in BUN and eGFR between the experimental group and the control group. CONCLUSIONS: Liraglutide reduced the levels of Blood Glucose, BMI, renal outcome indicators, and serum inflammatory factors of patients with T2DN, suggesting the beneficial effects of liraglutide on renal function.

Acute kidney injury and its association with mortality in Asian COVID-19 patients: A meta-analysis.

BACKGROUND: Previous evidence suggests that acute kidney injury (AKI) is common in patients with COVID-19 and associated with adverse outcomes. Moreover, the incidence and mortality of AKI in Asia are ambiguous. OBJECTIVE: Evaluating the risk factors and risk of death from AKI in -COVID-19 patients in Asia. MATERIALS AND METHODS: We conducted a meta-analysis of clinical observational studies of -COVID-19 patients in Asia. Outcome measures included: AKI in COVID-19 patients, overall mortality in COVID-19 patients, and mortality assessment in patients with AKI. The random-effects model was adopted, with heterogeneity and sensitivity analysis. RESULTS: 27 clinical studies (18,216 Asian patients with COVID-19) have been included in the study. The pooled incidence of AKI was 0.19 (95% CI 16 - 23%; I2 = 98.9%, p < 0.001); the pooled incidence of total mortality was 0.19 (95% CI 17 - 22%; I2 = 98.9%, p < 0.001). No publication bias was found (Egger's test, p = 0.396, 0.213). The pooled mortality in AKI patients with COVID-19 was 50% (95% CI 33 - 67%; I2 by random-effects model = 98.4%, p < 0.001). AKI was found to be a risk factor for death in stepwise regression analysis; age, diabetes, and hypertension were influencing factors for AKI risk in -COVID-19 patients. CONCLUSION: AKI is a common complication in Asian COVID-19 patients, and it is associated with an increase in mortality of Asian COVID-19 patients. Any treatment that protects the kidney may be a practical intervention to reduce the mortality of COVID-19 patients in Asia.
