Effect of Xiaoyu Zhixue Tablet (消瘀止血片) on Expression of Platelet Membrane Glycoproteins in Patients with Hemorrhagic Thrombopathy

Objective: To observe the effect of Xiaoyu Zhixue tablet (消瘀止血片,XYZXT) on the expression of platelet membrane glycoproteins in patients with hemorrhagic thrombopathy, and to explore its possible mechanism. Methods: The total of 148 patients with hemorrhagic thrornbopathy 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) Ⅰ b/Ⅸ, GP Ⅱ b/Ⅲ a complexes, GP Ⅰ b, GP Ⅱ b, GPⅢ a 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, GP Ⅱ b/Ⅲ a complexes, GP Ⅰ b, GP Ⅲ a 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 Ⅰ b/Ⅸ, GP Ⅱ b/Ⅲ a complexes, GP Ⅰ b, GPⅢ a and P-selectin at the level of receptor protein.

The therapeutic effect and the recovery rate of platelet aggregation in the two groups were observed. And platelet membrane glycoprotein (GP) Ib/IX, GPII b/IIIa complexes, GPIb, GPIIb, GPIIIa 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 (X ²=45.83,P<0.01), and the recovery rate of platelet aggregation was 72.4% and 4.0% respectively (X ² = 62.06,P<0.01). The fluorescence intensity of GP I b/IX, GP II b/III a complexes, GPIb, GP IIIa 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 I b/IX, GPII b/IIIa complexes, GP I b, GPIIIa and P-selectin at the level of receptor protein.

Redistribution of platelet membrane glycoprotein iv and release of intracellular α-granule thrombospondin in patients with chronic myelogenous leukemia

Summary The redistribution of platelet membrane glycoprotein IV (GPIV) and the release of intracellular α-granule thrombospondin (TSP) were examined and the inhibition of β-thromboglobulin (β-TG) and platelet factor 4 (PF4) in patients with chronic myelogenous leukemia (CML) was observed and quantitation of β-TG and PF4 in sera was conducted. GPIV in inactive platelet from CML was 36080± 17010 molecules/platelet as compared with 13190±4810 from the controls (P< 0.01). No abnormality was found in the distribution of platelet membrane GPI_b and GPII_b/III,(P> 0.05). The GPIV redistribution on active platelet membrane induced thrombin (IU/ml) from CML and healthy donors was 44320 ±32310 and 22800± 12700 molecules/platelet respectively (P< 0.01). The difference in the release of intracellular α-granule TSP between CML and the control group was not found (P> 0.05). There was no direct correlation between GPIV expression and TSP binding after platelet activation. The high levels of β-TG and PF4 in sera inhibited release of intracellular α-granule TSPin vitro. These results indicate that the abnormality of platelet membrane GPIV is a common marker in CML, therefore the specific increase of platelet GPIV in patients with CML may be a useful tool for the diagnosis and monitoring of the platelet dysfunction. The release of internal TSP pools is hindered by either β-TG or PF4 in sera. This project was supported by the National Natural Science Foundation of China (No. 39370322).
