Methods: The total of 148 patients with hemorrhagic thrombopathy were randomly divided into two groups, the traditional Chinese medicicne (TCM) group (n=98) treated with XYZXT and the Western medicine (WM) group (n=50) treated with adrenosin, vitamins C, K and P, both for 6 months. The therapeutic effect and the recovery rate of platelet aggregation in the two groups were observed. And platelet membrane glycoprotein (GP) Ⅰb/Ⅸ, GPⅡb/Ⅲa complexes, GPⅠb, GPⅡb, GP Ⅲa and P-selectin were analyzed by flow cytometry in both groups before and after treatment and also in 34 normal healthy subjects. Results: The total effective rate of hemostasis was 89. 8% in TCM group and 54. 0% in the WM group (x2=45.83, P<0.01), and the recovery rate of platelet aggregation was 72.4% and 4.0% respectively (x2=62.06, P<0.01). The fluorescence intensity of GP Ⅰ b/Ⅸ, GPⅡb/Ⅲa complexes, GPⅠb, GPⅢa and P-selectin were lower in both groups before treatment than those in the healthy subjects. Expression of above-mentioned marks was elevated in TCM group after 6 months' therapy, which was insignificantly different as compared with the healthy subjects (P>0.05) and higher than those in the WM group (P<0.05). Conclusion: One of the mechanisms in treating hemorrhagic thrombopathy with XYZXT is that it could regulate the expression of GP Ⅰb/Ⅸ, GPⅡ b/Ⅲa complexes, GPⅠb, GPⅢa and P-selectin at the level of receptor protein.展开更多

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: Fifty-one patients with CRF in early metaphase (treated group) were treated with XYZXT, 3 months as the course of treatment for 2 courses. The previous therapies remained unchanged. Flow cytometry was used to assess the expression of platelet GP Ⅰb/Ⅸ/Ⅴ complex and GP Ⅰb α in patients with CRF, and turbidity method was used to determine the platelet maximum aggregation rate (MAR), meanwhile the renal function was measured. The final data were compared with those before the treatment, and with those in the normal control group (31 healthy subjects). Results: Compared with the normal control group, expressions of GP Ⅰ b/Ⅸ/Ⅴ complex and GPⅠb α, and platelet MAR in CRF patients were significantly lower (P=0.007,P=0.001,P=0.009) before the treatment; after the treatment with XYZXT, the above indexes in CRF patients were remarkably increased (P=0.033,P=0.026, P=0.045), but still lower than those in the normal control group, however, it was not statistically significant. Conclusion: (1) The expression of GP Ⅰ b/Ⅸ/Ⅴ complex in CRF patients of early metaphase was decreased, which lead to platelet aggregation dysfunction. This might be one of the reasons for the hemorrhagic trend in CRF. (2) XYZXT was able to upgrade expressions of GP Ⅰb/Ⅸ/Ⅴ complex and GPⅠb α in CRF patients, improve platelet function and clown-regulate platelet activation in patients with CRF.展开更多
