Objective To observe the effects of Dl-3-n-butylphthalide ( NBP) on the mitochondria infarction, size of myocardial infarction and myocardial apoptosis after acute myocardial ischemia in rats. Methods 92 male SD rats were divided into sham operation group (8 rats) , model group (21 rats) , and low-dose NBP group (21 rats) , medium-dose NBP group (21 rats) , high-dose NBP group (21 rats) . The model and NBP groups were made into MI model by ligation of the left anterior descending ( LAD) coronary artery, but not in sham-operated group. Model group and NBP group were taken heart specimens after coronary artery ligation. Cardiomyocyte apoptosis was ana-lyzed by TUNEL in each group. Size of MI was analyzed by TTC staining in sham-operated group, model group and high-dose NBP group. Electron perspective microscopy was applicated in observing mitochondria infarction in model group and high-dose NBP group after myocardial infarction. The expressions of Bcl-2 protein and Bax protein were detected by Western blot. Results Compared with model group, butylphthalide significantly increased expression of Bcl-2 protein ( P <0.05 ) and the ratio of Bcl-2/Bax ( P <0.05 ) , inhibited mitochondria infarction ( P <0.05 ) , reduced myocardial infarct size ( P<0.01 ) and cardiomyocyte apoptosis ( P<0.05 ) . Conclusion Bu-tylphthalide significantly inhibits myocardial infarction by increasing expression of Bcl-2 protein and the ratio of Bcl-2/Bax and decreasing mitochondria infarction, reducing myocardial infarct size and cardiomyocyte apoptosis in rats during the acute myocardial ischemia process.

Objective: To develop a new quantitative determination method for the biological activity of recombinant human ciliary neurotrophic factor. Methods: Dorsal root ganglions were derived from the chick embryo and dispersed into single neuron cell,The rhCNTF was added to neuron cells and incubated for 64 hours,The activity of acid phosphatase in neuron cells was determined and the biological activity of rhCNTF was analyzed quantificationally. Result: rhCNTF could promote original era dorsal root neuron cells of chick embryo surviving,the livability of neuron cells was positively related to the amount of rhCNTF added to the culture. Conclusion: A quantitative determination method for the biological activity of rhCNTF was developed by testing the activity of acid phosphatase in neuron cells. Compared with the typical ways,this method was quantificational easily,repeatable better and with much fewer disturbance factors.

Objective To evaluate the usage of renoportal anastomosis in the liver transplanta- tion.Method The successful experience about renoportal anastomosis for portal vein reconstruction in liver transplantation was reported,and related literature reviewed.Results Including our case,there have been 13 cases of liver transplantation using renoportal anastomosis for portal vein reconstruction. Among these patients,8 cases were complicated with diffuse portal vein thrombosis,and 10 cases had a splenorenal shunt(spontaneous shunt in 3 and surgical shunt in 7).Complications related to portal vein hypertension occurred in 3 cases(transient ascites in 2 cases and severe digestive bleeding in 1 case)after liver transplantation.There were 3 deaths which were not related to renoportal anastomo- sis.Conclusion Renoportal anastomosis is a safe and feasible technique in liver transplantation for the patients with diffuse portal vein thrombosis or with splenorenal shunt(spontaneous or surgical shunt).
