Correlation study between pre-operative platelet aggregation rate and peri-operative blood product application in patients with off-pump coronary artery bypass grafting

Objective To explore the impact of pre-operative platelet aggregation rate(PAR)on off-pump coronary artery bypass grafting(OPCABG),meanwhile to study the relationship between platelet function and blood product application during peri-operative period in relevant patients.Methods A total of 172 patients receiving OPCABG in our hospita from 2014-01 to 2015-09 were en-

Effects of Ixeris Sonchifolia on Platelet Function and Hemorrheology of Type 2 Diabetes Mellitus Patients

Objective: To observe the effects of Ixeris sonchifolia Hance (ISH) on platelet function and hemorrheology in type 2 diabetes mellitus (DM) patients. Methods: Thirty-three type 2 DM patients were treated with 20 ml ISH per day, intravenously dripping for 15 days; 31 patients in the red sage treated group were treated with composite red sage injection intravenous dripping for 15 days, and their changes of platelet membrane glycoprotein Ⅱb/Ⅲa compound (GPⅡb/Ⅲa), granular membrane protein-140 (GMP-140), platelet aggregation rate (PAgR) and hemorrheology were observed. Results: After treatment with ISH, the GPⅡb/Ⅲa compound positive rate of 33 type 2 DM patients were lowered (P<0.05), GMP-140 showed lowering trend, PAgR obviously reduced, and compared with before treatment it showed significant difference; comparison between the two groups after treatment,it showed significant difference (P<0.05, P<0.01). At the same time, the various parameters of hemorrheology displayed significant improvement. There was no adverse effect during the course of treatment. Conclusion: ISH could improve platelet function and abnormal hemorrheology of type 2 DM patients, which is vital for the treatment of DM and their vascular lesion.

Effect of Xiaoyu Zhixue Tablet(消瘀止血片) on the Expression of Platelet Membrane Glycoprotein Ⅰb/Ⅸ/Ⅴ Complex in Patients with Chronic Renal Failure

Objective： To investigate the effect of Xiaoyu Zhixue Tablet （消瘀止血片, XYZXT） on the expression of platelet membrane glycoprotein （GP） Ⅰ b/Ⅸ/Ⅴ complex and GP Ⅰ b α in patients with chronic renal failure （CRF） in early metaphase. 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.
