ObjectiveTo investigate the detection results of WBC,CRP,ESR and GR% in patients with knee infection after operation. Methods The study was conducted from March 2012 to January 2015. Twenty patients were collected in the study. The values of WBC,CRP,ESR and GR% were compared and analyzed between pre-operation and post-operation of 1,3 and 7 days. Results The values of WBC,CRP,ESR and GR% in the post-operation of 1 day were higher than those in the pre-operation,and there were statistically significances (P < 0.05). The values of ESR in the post-operation of 3 and 7 days were higher than that in the pre-operation, with statistically significances(P < 0.05). However,the values of WBC,CRP and GR% in the post-operation of 3 and 7 days were no statistically significances compared with those in the pre-operation(P > 0.05). Conclusion WBC,CRP,ESR and GR% have good reference value for early diagnosis and treatment,which can be used as screen testing indexes in the early knee infection.

OBJECTIVETo discuss the hemostasis of the different polarities of Platycladi Cacumen Carbonisatum (PCC) on the blood heat and hemorrhage syndrome rat model induced by dry yeast.
METHODThe SD rats were divided into seven groups. Yunnan Baiyao was taken as the positive control drug. The rats in the control group and model group were fed with CMC-Na for 7 days, and the rats in other groups were fed with corresponding drugs simultaneously. On day 7, the blood heat and hemorrhage syndrome rat model was established. Indexes including the whole blood viscosity, plasma viscosity, thrombin time (TT), activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen content (FIB), red blood cell (RBC), hemoglobin (HGB), hematocrit (HCT), blood platelet count (PLT), thrombocytocrit (PCT), mean platelet volume (MPV), platelet distribution width (PDW) and the rate of platelet aggregation induced by ADP were detected. Additionally, the pathological examinations of lungs among each group were compared.
RESULTCompared with the control group, the RBC, HGB and HCT of rats in the model group increased significantly, with distinct increase in high, middle and low whole blood viscosity and plasma viscosity of rats in the model group; TT and APTT were notably prolonged, while PT was notably shortened, with significant increase in FIB content; PLT, PCT, MPV and PDW remarkably increased; Additionally, the rate of platelet aggregation induced by ADP significantly decreased. After ig administration of the ethyl acetate extract of PCC, the low whole blood viscosity and plasma viscosity remarkably decreased; TT and APTT were significantly shortened, with notable reduction in PDW and in FIB content Additionally, the rate of platelet aggregation induced by ADP significantly increased. The injury of lungs was also improved in ethyl acetate extract group. The rate of platelet aggregation induced by ADP of n-butanol extract group notablly increased. Plasma viscosity of water extract group remarkably decreased, with TT being significantly shortened. But the effects of n-butanol extract or water extract were weaker than that of ethyl acetate extract. And the effect of petroleum ether extract was the weakest.
CONCLUSIONEthyl acetate extract is the active part of PCC, showing the effect of hemostasis by reducing the low whole blood and plasma viscosity, improving coagulation function mainly by acting on the endogenous coagulation, and ameliorating the function of platelet aggregation.
