This study explores the effects of XYC on heart failure(HF) and its detailed mechanisms.Methods: Isoproterenol(ISO, 30 mg/kg) was injected intraperitoneally for 7 days to copy a HF model of 10-12 weeks old, 20-30 g male mice. We then compared the CON(control) group, ISO(HF model)group, MET(metoprolol) group, and XYC group. Cardiac systolic function and left wall thickness were evaluated by echocardiograph. Using western blot analysis, we detected the proteins of calmodulin dependent protein kinase Ⅱ(Ca MKII) and sarco/endoplasmic reticulum Ca^(2+)-ATPase(Serca). Furthermore, ts A201 cells were cultured and the human CaV1.2 calcium channel current(hCaV1.2) were detected by patch clamp experiments.Results: XYC reduced HF, inhibiting the protein expression of Ca MKII, but Serca did not change significantly. Moreover, XYC inhibited the peak amplitude of the hCaV1.2 current, depolarizing shifted the activation curve 27.6 mV, and shifted the inactivation curve toward a positive potential 17.6 mV. The fraction recovered from inaction was reduced in XYC group compared with that in CON group.Conclusion: XYC could inhibit ISO-induced HF by reducing the Ca^(2+)/Ca MKII signaling pathway in mice.展开更多

METHODS: The five major components, including protopanaxadiol, tanshinone IIA, emodin, chlorogenic acid, and nuciferine, were extracted from Jiangzhi granules. Their cytotoxicity was assessed to determine the safe dose of each component for HepG2 cells. HepG2 cellular steatosis was induced using 1 mmol/L of free fatty acids (FFAs) for 24 h, and then treated with each component at high, intermediate, and low doses (500, 50, and 5 μmol/L), respectively for another 24 h. The effects on HepG2 steatosis were observed directly under optical phase microscopy, or through oil red O staining and Nile red assays. In addition, the levels of reactive oxygen species (ROS) in the steatotic HepG2 cells with and without high-dose protopanaxadiol treatment were measured using fluorescent dye 2′,7′-dichlorodihydrofluorescein diacetate staining. RESULTS: No obvious cytotoxicity was observed in the HepG2 cells incubated with each of the five components at up to 500 μmol/L. At 24 h after incubation with FFAs, the HepG2 cells swelled and many lipid droplets accumulated. The lipid content was attenuated after 24 h of incubation with protopanaxadiol, tanshinone IIA, and emodin at 500 or 50 μmol/L (P<0.05), especially with 500 μmol/L protopanaxadiol (P<0.01). In addition, the ROS level was elevated in steatotic cells, but decreased after intervention with 500 μmol/L protopanaxadiol (P<0.05). CONCLUSION: Protopanaxadiol, tanshinone IIA, and emodin alleviate hepatocellular steatosis in a dose-dependent manner, and oxidative stress regulation may partially contribute to the effects of protopanaxadiol.展开更多

Methods: Sixtythree AS patients were randomly divided into the treated group ( n = 33, treated with TMJZ, 10 ml each time, three times a day) and the control group (n = 30, treated with Lovastatin, 10 mg, once daily). The levels of serum lipids (enzymatic methods), Ps, vWF, and D-D were measured before and after 8 weeks of treatment. Results: Serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), apo-protein B-100 (apoB-100) were significantly decreased (P＜0.05 or P＜ 0.01) and high-density lipoprotein cholesterol (HDL-C) was significantly raised (P＜0.05) after TM JZ treatment. Serum Ps,vWF, and D-D also declined (P＜0.05) after treatment. There was no significant difference between the treated and the control groups in these parameters except serum HDL-C level. Conclusion: TMJZ has good therapeutic effect in regulating serum lipids, improving endothelial cell function, inhibiting activation of platelets, and preventing the disturbance of blood coagulation/fibrinolysis function in patients with AS.展开更多

文摘Objective:To establish a reliable and sensitive method for evaluating quality of Yiqi Jiangzhi Granules(YQJZG).Methods:Ultra performance liquid chromatography electrospray ionization tandem mass spectrometry(UPLC-ESI-MS/MS)was employed for simultaneous determination of eight marker components.Separation was performed on an AQUITY UPLC;HSS T3 column,the mobile phase consisted of acetonitrile as the organic phase and 0.1%(volume percentage)formic acid as the aqueous.Eight marker components,ginsenoside Rg1(GRg1),ginsenoside Re(GRe),ginsenoside Rb1(Gb1),typhaneoside(TEO),isorhamnetin-3-O-neohespeidoside(IN),hesperidin(HPD),aurantio-obtusin-6-O-β-D-glucoside(AG)and curcumin(CCM),were detected by multiple reaction monitoring(MRM)mode.The Chinese Pharmacopoeia(2020 edition)was regarded as the guidance document for this method validation.Results:The method showed good linearity(R^(2)≥0.9990).The relative standard deviation(RSD)values for the instrument precision,intermediate precision and repeatability were less than 2.91%,2.88%,and 3.54%,respectively.The average recovery varied from 91.08%to 103.89%,with RSD below 3.81%.Sample solutions were found to be stable within 24 h at 4℃(RSD<2.85%).Eight marker components were successfully determined from three batches of YQJZG.Conclusion:The proposed UPLC-ESI-MS/MS method was found to be simple,fast and sensitive,and can be used for the routine quality assessment of YQJZG.Simultaneously,this method may provide a new and powerful tool of quality control for other traditional Chinese medicine analogous formulae.
