Background:Myasthenia gravis is a common autoimmune disease in clinic. Although there are various ways and drugs for the treatment of myasthenia gravis in Western medicine, there are still a variety of adverse reactions. Studies have shown that Buzhong Yiqi decoction combined with Western medicine has a certain efficacy in the treatment of myasthenia gravis, but there is a lack of evidence-based medicine. The research carried out in this scheme is to systematically evaluate the efficacy and safety of Buzhong Yiqi decoction combined with Western medicine in the treatment of myasthenia gravis, and to provide reliable evidence for guiding clinical practice.Methods:English databases (the Cochrane Library, PubMed, Web of Science, Embase) and Chinese databases (China Biomedical Database, China Science and Technology Journal Database, China National Knowledge Infrastructure, Wanfang) will be searched by computer. In addition, Baidu Academic and Chinese Clinical Trial Registration Center will be searched manually. A randomized controlled clinical trial of Buzhong Yiqi decoction combined with Western medicine in the treatment of myasthenia gravis will be conducted from the establishment of the database to December 2020. The 2 researchers independently carry out data extraction and literature quality evaluation on the quality of the included study, and meta-analysis of the included literature will be carried out by using RevMan 5.3 software.Results:This study will evaluate the efficacy and safety of Buzhong Yiqi decoction combined with Western medicine in the treatment of myasthenia gravis by Quantitive MGscore, the number of Tregs cells and the content of anti-acetylcholine receptor antibody (AchR-Ab).Conclusion:This study will provide reliable evidence-based evidence for the clinical application of Buzhong Yiqi decoction combined with Western medicine in the treatment of myasthenia gravis.Ethics and dissemination:Private information from individuals will not be published. This systematic review also does not involve endangering participant rights. Ethical approval was not required. The results may be published in a peer-reviewed journal or disseminated at relevant conferences.OSF Registration number:DOI 10.17605/OSF.IO/MXUPK.

Pharmacokinetics of different dosage of astragalus membranaceus of buyang huanwu decoction in rats with cerebral ischemic injury by microdialysis combined with LC/MS

To investigate the pharmacokinetics of effective components of Bu Yang Huang Wu Decoction (BYHWD) with different dosages of Astragalus (Yiqi groups and Huoxue groups ) applicating in rats with middle cerebral artery occlusion (MCAO). Replicating the animal model of cerebral ischemia-reperfusion in rats, establishing the liquid-mass spectrometry method for the determination of BYHWD and researching the pharmacokinetics of effective components of yiqi groups of BYHWD with different dosages of astragalus (3.09, 6.17, 12.34 g/Kg) and Huoxue goups (2.32 g/Kg) when applicated seperately in the rats suffering from cerebral ischemia reperfusion injury after femoral vein administration. The pharmacokinetics of formononetin and paeoniflorin in the different dosage groups of BYHWD met the one-compartment model, and the t_1/2 of formononetin and paeoniflorin in the low-dose Yiqi and Huoxue groups were (88.43±3.82, 69.18±0.11) min, MRT were (138.56±4.83, 113.62±2.42) min, and AUC_0–t were (28 488.35±4800.32, 140 614.80±23 954.05) ng/mL·min; The t_1/2 of formononetin and paeoniflorin in the middle-dose Yiqi group and Huoxue group were (82.16±1.78, 67.08±3.69) min, and MRT were (127.95±2.70, 116.58±4.13), AUC_0–t were (48 619.25±6745.75, 159 026.00±15 003.33) ng/mL·min; The t_1/2 of formononetin and paeoniflorin in the high-dose Yiqi and Huoxue groups were (80.29±1.12, 69.69±0.87) min, and MRT was (128.79±1.46, 118.78±4.56) min, AUC_0–t were (109 942.90±13 101.83, 189 417.90±22 311.00) ng/mL·min. The concentration rate of formononetin t_{1/2 brain} was decreased with increase of Astragalus dose. However, no significant difference between these two variables was found during experiments. Furthermore, the experiments showed that the increasing dose of astragalus would affect the pharmacokinetic behavior of paeoniflorin in the Huoxue groups. More specifically, the result showed that paeoniflorin can be metabolized more slowly in the body when applicated in high dose of the jaundice administration groups . In this way, the effect of paeoniflorin can be lasted for longer time in the body and brain.
