Objective To explore the effect of xue-shuan-tong(panax notoginsang saponins,PNS)or isovalaemic haemodilution(IHD)and PNS combining IHD treatment on activities of fibrinolysis and hemorrheology in patients with retinal vein occlusion (RVO). Methods Seventy-three patients with RVO were allocated at random to 3 groups which were treated with PNS,IHD and PNS combining IHD.The activities of t-PA and PAI,rheological parameters and visual acuity before and after treatment were observed. Results At the end of treatment,significantly increased activity of t-PA and decrease of PAI was found in combined treatment group and PNS group,but the difference before and after treatment was not significant in IHD group.Furthermore,except the plasma viscosity in IHD group,the other hemorrheological parameters in all the petients of 3 groups revealed to be improving.One month after treatment,the parameters return completely to normal in both PNS and IHD groups; while the whole blood apparent relative viscosity in low shear rate,RBC aggregation and RBC deformability maintained still in lower level,and also the visual acuity resumed better and quicker in combined group. Conclusion Combined treatment of PNS and IHD can both regulate the activity of fibrinolysis and decrease the blood viscosity of patients with RVO for a period of relatively long time and increase the effect of treatment.

ObjectiveTo evaluate the effect of dilute autotransfusion in liver resection for patients with hepatic hydatid disease. MethodThirty patients with hepatic hydatid disease met the inclusion criteria were included. The changes of intraoperative hemodynamics, internal environment, and each system functions at different time point were observed. Results①There were no significant differences among mean arterial pressure, central venous pressure, heart rate in all the patients at each time point (P > 0.05), while, the other indexes including the concentrations of hemoglobin (Hb), hematocrit (Hct) after blood collection were all greatly lower than those before blood collection (P < 0.05), Na+, K+, Cl-, pH, and base excess after blood collection were all greatly lower than those before blood collection (P < 0.05). But all the indexes above mentioned (except for ph and base excess) returned to normal.②Compared with these indicators before surgery, the blood concentrations of AST, ALT, cardiac troponin I, and creatinin were all greatly increased (P < 0.05), the blood concentrations of Hb, Hct, platelet were all decreased apparently after surgery 1 day (P < 0.05). The prothrombin time and activated partial thromboplastin time were all prolonged (P < 0.05). But after surgery one week, those indicators had rebounded to the normal range. ConclusionThe application of dilute autotransfusion in liver surgery for patients with hepatic hydatid disease is safe, feasible, and saving.
