Qishen Yiqi Dripping Pill Protects Against Diabetic Nephropathy by Inhibiting the Wnt/?-Catenin and Transforming Growth Factor-?/Smad Signaling Pathways in Rats.

ABSTRACT: Diabetic nephropathy is a severe microvascular complication of diabetes. Qishen Yiqi dripping pill (QYDP) has been reported to be a renal protective drug. However, the mechanisms remain unclear. This study was performed to investigate the mechanisms. In this study, Sprague-Dawley rats were injected with streptozotocin to generate a diabetes model. Diabetic rats were administered 150 or 300 mg/kg/day QYDP. After 8 weeks of treatment, serum creatinine, serum blood urea nitrogen, and 24-h urinary albumin were measured. Kidney histological staining and immunostaining were analyzed. Then, the renal tissue was analyzed with a genome expression array. The results showed that QYDP treatment reduced serum creatinine, blood urea nitrogen, and 24-h urinary albumin and improved kidney histology and fibrosis. The gene array revealed that the expression of 189 genes was increased, and that of 127 genes was decreased in the high dosage QYDP group compared with the diabetic group. Pathway and gene ontology analyses showed that the differentially expressed genes were involved in the Wnt/?-catenin and transforming growth factor-? (TGF-?)/Smad2 signaling pathways. QYDP reduced the renal Wnt1, catenin ?1, Tgfb1, and Smad2 gene expression and ?-catenin, TGF-?, Smad2, collagen I, ?-smooth muscle actin, and fibronectin protein expression in diabetic rats. Our results provide the first evidence that QYDP performs its renal-protective function by inhibiting the Wnt/?-catenin and TGF-?/Smad2 signaling pathways in diabetic rats.

Project description:Background: The number of heart failure with preserved ejection fraction (HFpEF) patients is increasing year by year, yet all western medicines currently used for heart failure have been shown to be ineffective for HFpEF. Qishen Yiqi Dripping Pill is one of the commonly drugs for the treatment of heart failure in China. In recent years, some clinical studies found that it has curative effect on HFpEF. Objective: To evaluate the efficacy and safety of Qishen Yiqi Dripping Pill in treatment of HFpEF. Methods: Databases including CNKI, Wanfang, VIP, CBM, PubMed, Web of Science, The Cochrane Library and EMbase were searched from their inception to May 2020 to screen relevant randomized controlled trials. The "risk of bias" evaluation tool in the Cochrane Handbook was used to evaluate the quality of the included studies. RevMan 5.3 software was used for meta-analysis. Results: Eight studies meeting the criteria were included, with a total of 895 patients. The results of meta-analysis showed that compared with western medicine alone, combination of western medicine and Qishen Yiqi Dripping Pill can further increase the quotient of early diastolic mitral inflow velocity and late diastolic mitral inflow velocity (E/A) in patients with HFpEF [mean difference (MD) = 0.20, 95% CI (0.14, 0.26), p < 0.000 01], decrease the quotient of early diastolic mitral inflow velocity and mitral annular tissue velocity (E/e') [MD = -2.50, 95% CI (-3.18, -1.82), p < 0.000 01], decrease brain natriuretic peptide (BNP) [MD = -151.83, 95% CI (-245.78, -57.89), p = 0.002], increase cardiac function improvement rate [relative risk (RR) = 1.30, 95% CI (1.11, 1.52), p = 0.001], and increase six-minutes walking distance (6-MWD) [MD = 64.75, 95% CI (22.65, 106.85), p = 0.003]. Four studies reported the occurrence of adverse reactions, among which three studies reported no adverse reactions and one study reported three patients with mild adverse reactions in the intervention group. Conclusion: Current evidence suggests that Qishen Yiqi Dripping Pill may be effective in the treatment of HFpEF. However, due to the low quality of the included studies, lack of placebo control, large heterogeneity among different studies, and great possibility of publication bias, the results of our review should be evaluated with more prudence, more high-quality clinical studies are needed to verify the conclusion in the future. In addition, the safety of Qishen Yiqi Dripping Pill remains uncertain, further assessment is required in the future.

Project description:BACKGROUND:Heart failure (HF) is associated with decreased quality of life, high re-admission rate and poor prognosis. In particular, ischemic heart failure (IHF) has a worse prognosis than nonischemic HF. The use of traditional Chinese medicine (TCM) alongside Western medicine to treat HF has developed into an integrative treatment model in China. There have been small clinical trials and experimental studies to demonstrate the efficacy of TCM for treating HF; however, there is still a lack of high-quality trials. Qishen Yiqi dripping pills (QSYQ), a TCM drug, have been commonly used alongside standardized Western medicine to treat IHF. This paper describes the protocol for the clinical assessment of QSYQ in IHF patients. METHOD:A randomized, double-blind, multicenter, placebo-controlled trial will assess the efficacy and safety of QSYQ in the treatment of IHF. The trial is to enroll 640 IHF patients from 32 hospitals in China. Besides their standardized Western medicine, patients will be randomized to receive treatment of either QSYQ or placebo for 6 months and follow-up monitoring for at least a further 6 months. The primary outcome is increased exercise capacity of patients, which will be measured using the 6-minute walking test (6MWT). The secondary outcomes include composite endpoints: all-cause mortality, frequency of hospitalization or emergency due to cardiovascular events, brain natriuretic peptide levels, left ventricular ejection fraction, and cardiothoracic ratio will be documented, as well as scores on the New York Heart Association classification and Minnesota quality of life index, and information obtained from the four TCM diagnostic methods. Blood lipid tests will also be administered. DISCUSSION:The integrative treatment model of TCM alongside Western medicine has developed into a treatment model in China. The rigorous design of the trial will assure an objective and scientific assessment of the efficacy and safety of QSYQ in the treatment of IHF.
