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.

Numerous peptides that bind to a given target have been selected by phage display technology. However, some peptides isolated to date do not bind with high affinity to tumor or organ sites, even peptides were selected in vivo. Therefore, the biodistribution of 99mTc-labeled filamentous phage peptide library via MAG3 (mercaptoacetyltriglycine) were investigated to gain a better understanding of phage circulation in vivo. The experimental results showed that the liver and spleen were the organs of the greatest accumulation, while heart, muscle, pancreas and brain retained less radioactivity. In opposite to other tissues and organs, the radioactivity in stomach, intestine and bone gradually went up with time. The clearance of 99mTc-labeled phage in blood was very fast from 5 min to 30 min and then slowed down. When phage in vivo circulated at enough long period of time, some phage particles could extravasate in some organs or tissues and internalized there. In conclusion, the circulation time of phage in vivo should be experimentally determined beforehand according to the targeted organs and the specific location of target peptides in order to panning a peptide with high specificity and affinity to that target.

Objective To investigate the effects of Buyanghuanwu decoction on infiltration of neutrophils and expression of ICAM-1 after middle cerebral artery occlusion (MCAO) in rats. Methods Rats were pretreated with Buyanghuanwu decoction(13 g/kg and 26 g/kg) for 7d and then subjected to cerebral ischemia/reperfusion injury induced by an MCAO. After a 90min ischemia and a 24h reperfusion, the neurological deficit and the survival neurons were determined. The effects of Buyanghuanwu decoction on infiltration of neutrophils and expression of ICAM-1 by immunohistochemistry are evaluated. Results Buyanghuanwu decoction significantly ameliorated the neurological deficit and increased survival neurons . The myeloperoxidase (MPO) positive cells and the ICAM-1 positive vessels in the vehicle-treated rats were increased significantly (P

Objective To investigate the impact of symbiotic probiotic fermentation on anti-tumor effect of Agaricus blazei polysaccharide. Methods Probiotic fermentation and non-fermentation of Agaricus blazei polysaccharide samples were divided into large (0.8 g/kg), middle (0.4 g/kg), small (0.2 g/kg) dose groups, and negative control group for a total of 7 group. The anti-tumor effect on tumor-bearing mice was observed. Results The highest inhibition rate of probiotic fermentation Agaricus blazei polysaccharides group was 53.71%, while that of non-fermatation of Agaricus blazei polysaccharide group was 38.90%. Conclusion Inhibition rate of probiotic fermentation samples of Agaricus blazei polysaccharide was significantly higher than non-fermentation samples. Probiotic fermentation can significantly improve the anti-tumor effect of the Agaricus blazei.

Objective To investigate into the indications and related anatomic foundation of transjugular intrahepatic portosystemic shunt(TIPS) creation by direct transcaval approach in patients with portal hypertension cirrhosis suffering unusual anatomy between the hepatic veins and portal bifurcation; and to evaluate the security, feasibility and clinical significance. Methods Direct transcaval approach TIPS were performed in 65 patients including active variceal bleeding (n=52), intractable ascites (n=12), and as a bridge to liver transplantation (n=1). Results Technical and functional success were achieved in all patients. The success rate was 100% without related complications including the technique and primary patency rate is obvious higher than classical TIPS. Conclusion In patients with unusual anatomy between the hepatic veins and portal bifurcation, and inaccessible or inadequate hepatic veins, transcaval TIPS creation is secure and feasible. The results suggest that the direct transcaval approach offering favorable primary patency because the shunt has a straight line in construction.

OBJECTIVE: To investigate the bacteria distribution, drug bacterial sensitivity characteristics of the rural chronic rhinosinusitis (CRS). And to explore the effect of antibiotic on pathogenic bacteria culture. METHOD: Choose nasal sinus secretions from 115 CRS patients living in rural areas. Aerobic bacteria culture, anaerobic bacteria culture and drug sensitive test were procedured for each sample. At the same time the use of antibiotics nearly 2 months and nearly 2 weeks were collected. RESULT: Among one hundred and fifteen specimens, 17 kinds of germs were detected in 37 cases, the positive rate of aerobic bacteria was 32.17%. Staphylococcus aureus and epidermis staphylococcus aureus the most common type of aerobe in CRS patients at rural areas. There was negative result in the anaerobic bacteria culture of 17 maxillary sinus specimen. The cases of using antibiotics nearly 2 months was up to 90, accounting for 78.26%. Nearly 2 weeks, 73 cases, accounting for 63.48%. The chi-square analysis showed high bacterial culture rate, in chronic rhinosinusitis with nasal polyps (CRSwNP group), which revealed correlation between bacterial infection factors and nasal polyps formation. For CRS patients with positive result of bacterial culture, they were sensitive to ofloxacin, cefotaxime, organism, ciprofloxacin, magnitude cephalosporin, and were drug fast to penicillin G, ampicillin, erythromycin. CONCLUSION No specific differences was found in the bacteria distribution of rural CRS. antibiotics abusage in rural CRS patients and the anaerobic bacteria culture techniques is the main factor resulting in low culture rate. Rational use of antimicrobial agents should be established on the basis of the bacterial culture and drug sensitive test.
