Efficacy of combined angiotensin II receptor blocker with tripterygium glycosides on diabetic nephropathy: A protocol for meta-analysis

Background:Several studies have reported good results for angiotensin II receptor blockers (ARB) combined with tripterygium glycosides (TGs) in the treatment of diabetic nephropathy (DN). However, because a small number of cases were included in each study, the statistical power was limited. Therefore, we performed a protocol for meta-analysis to further evaluate the clinical efficacy and safety of combined ARB and TGs in treatment of DN.Methods:The protocol was written following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement guidelines. We searched PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data, Science Direct up to April 2021. Outcome measures were 24-h urinary total protein, urinary albumin excretion rate, serum creatinine, blood urea nitrogen, albumin, hemoglobin A1c, β2-microglobulin and serum glutamic pyruvic transaminase. The risk of bias assessment of the included studies was performed by two authors independently using the tool recommended in the Cochrane Handbook for Systematic Reviews of Interventions (version 5.1.0). We performed meta-analysis using STATA 11.0.Results:The review will add to the existing literature by showing compelling evidence and improved guidance in clinic settings.Conclusion:The findings will provide helpful evidence for the application of combined ARB and TGs in the treatment of DN.OSF registration number:10.17605/OSF.IO/ARGE3     

Effects of different inotropic interventions on myocardial function in the developing rabbit heart

The development of the mammalian heart is characterized by substantial changes in myocardial performance. We studied the ontogeny of myocardial function with and without various inotropic interventions in the developing isolated, antegrade-perfused rabbit heart (2d, 8d, 14d, 28d, n = 96). Myocardial function was related to the protein expression of the sarcolemmal Na⁺-Ca²⁺ exchanger and to the sarcoplasmic Ca²⁺-ATPase. In neonatal hearts an age-dependent increase in maximal developed pressure velocity (dP/dt_max) by 45 % and peak negative pressure velocity (dP/dt_min) by 75 % within days 2 to 8 were observed. In response to inotropic intervention with isoproterenol, ouabain, calcium and the Na⁺-channel modulator BDF 9148, dP/dt_max and dP/dt_min increased in a concentration dependent manner. Significant differences between neonatal, juvenile and adult hearts could be demonstrated in a repeated measurement ANOVA model on the concentration-response curves for BDF 9148 (dP/dt_max and dP/dt_min), ouabain (dP/dt_min) and calcium (dP/dt_min), but not for isoproterenol. At the maximum isoproterenol concentration of 1 μmol/l, the increase in dP/dt_max and dP/dt_min was significantly higher in adult compared to neonatal hearts (t-test, p < 0.01). The significant decline of the Na⁺-Ca²⁺ exchanger protein expression from neonatal (1822 ± 171) to adult hearts (411 ± 96 S.E.M. [units per 20 μg protein], p < 0.01) was related to an increase in myocardial function (dP/dt_max r = 0.63, p < 0.01, dP/dt_min r = 0.62, p < 0.01). Contractility, relaxation and the observed positive inotropic effects were in general significantly lower in neonatal compared to adult hearts. In the individual heart an increase in contractility and relaxation was related to a decrease in Na⁺-Ca²⁺ exchanger expression. Received: 22 May 2000, Returned for 1. revision: 21 June 2000, 1.

Role of Endogenous Brain “Ouabain” in The Sympathoexcitatory and Pressor Effects of Sodium

Endogenous cardiac glycoside inhibitors of the Na, K-ATPase (called “ouabain” here) with structures similar to plant ouabain have been isolated in several tissues, including the adrenal cortex and the brain. Recent studies have demonstrated that “ouabain” in the anteroventral third ventricle (AV3V) region of the hypothalamus mediates the sympathoexcitatory and pressor responses to a high sodium diet in Dahl salt-sensitive (Dahl-S) and spontaeously hypertensive (SHR) rats. Although the mechanisms regulating the biosynthesis, release and deactivation of CNS “ouabain” remain unknown, the discovery of the importance of brain “ouabain” in cardiovascular regulation creates a novel path for the development of antihypertensive pharmacopeia
