ObjectiveTo explore the clinical effectiveness of intralesional glucocorticoid therapy on infantile hemangioma in proliferative stage,and variance of vascular endothelial growth factor(VEGF) expression in the hemangioma tissues.MethodsExperimental group:5 cases were injected with triamcinolone acetonide 3 days before operation,5 cases were done 6 days before operation,5 cases were done 9 days before operation and 5 cases were done 2 weeks before operation(the dose of injection was 1 mg/cm2 per time,but not exceeding 2 mg/kg).Control group:5 infantile hemangioma cases in involuting stage and 5 infantile hemangioma cases in proliferative stage did not received any therapy.The specimen of the hemangioma were collected to detect the expression of VEGF by two-step immunohistochemistry.Every optical slice was detected by 5 campus visualis of high power lens.ResultsObserving the specimen dyed by HE in the light microscope,there was no significant difference between injected group and non-injected group.But by means of immunohistochemistry,the expression of VEGF could been down regulation by the glucocorticoid(F=17.919 1P

A method for measurement of neutrophil function and opsonic activity by chemiluminescence (CL) was reported in this paper.The factors influencing the emission of CL were discussed. The experimental results suggested that CL depends on the concentration of luminol, the dilution of serum opsonin, the number of neutrophils and the environmental temperature. The optimum conditions defined in present study were: the concentration of luminol was 1?105M, the number of neutrophils 2?106/mml, the reactive temperature 37℃. According to the relationship between CL emission and the bactericidal activity of phagocytizing neutrophils, the measurement of CL may be used as a rapid, simple and usefull tool to determine the funetion of humoral-phagocyte axis.

Objective To explore the influence of cirrhotic portal hypertension and its complications on liver transplantation. Methods The literatures of the recent years on influence of hepatic cirrhotic portal hypertension on liver transplantation were reviewed. Results Splenomegaly, hypersplenism, portal vein thrombosis, portosystemic shunt and collateral flow in cirrhotic patients will increase the difficulty of liver transplantation and lead to more postoperative complications. Appropriate handling of these conditions can achieve a higher success rate of liver transplantation. Conclusion Correct management of end-stage cirrhotic portal hypertension and its complications can expand the indications of liver transplantation and improve long-term survival rates.

OBJECTIVE: To obtain and mutate a marine Bacillus megaterium to resolute pharmaceutical intermediate, 3-chloro-1,2-epoxypropane. METHODS: From marine sediment, a 3-chloro-1,2-epoxypropane-resolute strain was isolated and mutated by ultraviolet rays and N+ ion. RESULTS: The strain was identified as Bacillus megaterium on the basis of biophysical and biochemical test. The optimum salinity for growth was 2%, and the result of optimum salinity showed that the microbe was a typical marine microorganism. A positive mutant exhibited excellent resolution with ee value of 99% and yield of 42%. CONCLUSION: The marine bacillus megaterium shows a large potential for industrial production.

It was investigated that the effect of various inducing mediums,times and temperatures on the number of the zoospores from Diasporangium sp.producing polyunsaturated fatty acid of Eicosapentaenoic acid(EPA) and Arachidonic acid(AA).The results showed that the zoospores were detected in various liquid mediums after 1 day,They were globose and about 23.9 ?m in diameter.And maximum number of spores was obtained 6 days after translocation of mycilium to carrot patches at 25℃.But the number of the zoospores was the most 8 days at the same condition.The highest germination rate of the fungus was obtained in the vegetative agar.

Objective:To evaluate the efficacy of transcatheter arterial embolization with detachable balloon for pulmonary arteriovenous fistula(PAVF). Methods: A 48 year old female with PAVF suffered intermittent emoptysis, fatigability, exertional dyspnea, and palpitations. CT and MRI demonstrated 2 PAVF in the module lobe on right side. Pre embolization super selective pulmonary angiography revealed 2 fistulae communicating to the sac of the lesion.Three detachable balloons were used for embolization of the feeding arterial branch.The diameter of detachable balloons was twice as that of the feeding arterial branch. The study of blood gases showed the arterial oxygen pressure was 6.5 kPa before operation, hemoglobin at 158 g/L. Results: No complications were apparent in our case. Two PAVF were completely occuluded by the embolization of a feeding branch. One month later, the arterial oxygen pressure increased to normal values, hemoglobin at 125 g/L and clinical symptoms disappeared. On postcontrast CT, the fistulas treated by the embolization of a feeding arterial branch were not enhanced. No symptoms and signs were found in follow up for 16 months. Conclusion: The percutaneous transcatheter embolization with detachable balloon is effective for PAVF. [

Objective To explore the effect of fatty liver on graft survival, especially with reference to macrovesicular and microvesicular steatosis and to evaluate the relationship between histological grading and inflammation activity. Methods Different degrees of rat fatty liver model were established by feeding rats a diet consisting of 79% standard diet, 20% lard and 1% cholesterol. By modified two cuff vascular anastomoses and end to end suture for bile duct, rat orthotopic liver transplantation was performed to evaluate the relationship between donor histological grading and survival rate. Results Low survival rate of macrosteatosis (grade Ⅲ) was found. Most rats died of liver failure in early days after transplantation. Pathological findings showed frequent hepatic necrosis. There was no significant difference between macrosteatosia(gradeⅠ) and the normal group. After transplantation, almost all of the fat was cleared by the end of the fourth week. Diminished steatosis and liver regeneration were found in macrosteatosis (gradeⅡ), while microsteatotic donors had higher survival rate than the other groups except the normal group. Conclusion Macrovesicular steatosis(grade Ⅲ) affects graft survival and these steatotic livers should not be used as donors. However, steatotic livers with mild macrovesicular steatosis (grade Ⅰ) and microvesicular steatosis(grade Ⅲ) do not influence recipient survival, so these livers can be used safely for liver transplantation. The ischemic damage should be considered when using livers of macrovesicular steatosis(gradeⅡ). Donors with numbering score more than 2.7 are correlated with the poor survival.
