Objective To observe the effect of kallikrein and ozagrel on hemorheology in the treatment of patients with acute cerebral infarction,provide a theoretical basis for clinical treatment.Methods 100 patients with acute cerebral infarction met the inclusion criteria were randomly divided into 50 cases of observation group and 50 cases of control group,the control group were received conventional drug therapy,the observation group were given kallikrein and ozagrel on the basis of the control group,kallikrein 0.15PNA /times,ozagrel 80mg one time,bid,14d for a course of treatment.The symptoms improvement were observed,the NIHSS score and ADL score were calculated after treatment,then the blood were extraced for detecting high shear viscosity of whole blood,red blood cell aggrega-tion index,hematocrit,fibrinogen,erythrocyte sedimentation rate,and the clinical efficacy were judged.Results The total effective rate of the observation group were 96% (48 /50),which of the control group were 66% (33 /50),the total effective of the observation group was significantly higher than the control group (χ2 =16.105,P <0.01);The high shear viscosity of whole blood,red blood cell aggregation index,hematocrit,fibrinogen,erythrocyte sedimentation rate,NHISS of the observation group and the control group after treatment were lower than before treatment (t =6.589 and 3.762,6.204 and 3.661,8.112 and 5.774,5.542 and 3.529,9.429 and 3.962,9.621 and 6.586,all P <0.05),the ADL score was significantly higher than before treatment(t =7.673 and 5.446,all P <0.05),the high shear viscosity of whole blood,red blood cell aggregation index,hematocrit,fibrinogen,erythrocyte sedimentation rate, NHISS of the observation group after treatment were lower than those of the control group (t =3.387,3.545,3.525, 3.288,3.302,4.988,all P <0.05),the ADL score was significantly higher than the control group (t =3.446,P <0.05).Conclusion The method containing kallikrein and ozagrel has exact clinical efficacy,can effectively improve blood rheology and cerebral blood perfusion ischemic area,promote neurological deficits and recover the ability of daily life,and its security is good,which is worthy of promotion.

Objective　To explore the ideal effective treatment of liver trauma. Methods　The injury state, treating methods, effect and death causes of 210 patients with liver trauma were retrospectively analysed. Results　Of the patients, the liver trauma was in degrees Ⅳ Ⅴ Ⅵ in 88 cases (41.9%). Among 198 cases treated with operation, 39 underwent partial hepatectomy, 13 with gauze packing, 146 with debridement and suturing. 2 receieved inferior vena cava repairing, 4 liver atrery ligation. 19 patients died of serious injury, the death rate was 9% (19/210). Of the 19 cases, 12 (63.2%) died of great amount blood loss. Conclusions　The treatment of liver trauma should depend on the degree of injury. The death rate could be reduced by shortening the preoperative time and decreasing the amount of blood loss. Gauze packing can be applied as a temporary way to save the patients life.
