AIM: To establish the technique of precision-cut fibrotic liver slice (PCLS) and grope the optimal cultural conditions for researching the liver xenobiotic metabolism in vitro and the drug interaction. METHODS: Complex factors (higher fat diet, alcohol and CCl 4) were used to make the animal model of liver fibrosis. Fibrotic liver slices were prepared and cultivation system was established. Lactate dehydrogenase (LDH) leakage, glutathione S-transferase (GST) activity and 3[4,5-Dimethythiazole-2-yl]-2,5- diphenyltetrazolium bromide (MTT) reduction were chosen as indexes to assess the viability of the slice in different thickness, medium pH and cultural time. RESULTS: Rats were in earlier hepatic fibrosis after administration for 3 weeks. When the thickness of slices was 300 ?m and medium pH was 7.0, the LDH leakage, GST activity and MTT reduction could maintain on a steady level in 6 h. CONCLUSION: A 300 ?m of thickness, 7.0 of medium pH and 6 h of cultural time are the optimal slicing and culturing conditions for fibrotic liver slice.

Objective To study the efficacy and adverse reactions of the treatment on different types of infantile hemangiomas (IH) with different doses of propranolol .Methods One hundred and fifty cases of IH without contraindications were randomly treated with different doses of propranolol (low dose group:1 mg?kg -1 ?d-1 ;high dose group:2 mg?kg -1 ?d-1 ) under ECG monitoring inferior half an hour to breastfeeding taking ,and stay in hospital for observation for 6 to 24 hours after the treatment . The patients returned to the hospital for review every month(ECG and blood RT ;lung function in necessary) .Results The curative effect is better on strawberry IH than that on flat IH ,also better on deeply IH than that on superficial IH .The adverse reactions oc‐curred relatively slight in the low dose group and there was no significantly statistical differences on the treatment effects between the both groups(P>0 .05) .Conclusion It is safe and effective to treat IH with propranolol .

Strain QJ16,one of some methanotrophic bacteria isolated from soil samples utilizing the separate device designed by our laboratory;was studied in detail and identified as one of the Genus methylomonas through 16S rDNA sequencing and comparison. The culturing and reaction conditions for methane utilization of this strain were investigated. The results indicated that the optimal conditions for the growth of strain QJ16 were methane gas as carbon source and the coexistence of NH4Cl and KNO3 as nitrogen source,the cultivation temperature of 30℃ and medium initial pH 6～7,and the optimal Cu2+ concentration of 15 ?mol/L.

Objective To evaluate the accuracy,practical value and methods of Doppler tissue imaging(DTI) in localizing the ventricular emergence site of accessory atrioventricular pathways.Methods Forty patients with pre-excitation syndrome were examined by DTI before intracardiac electrophysiologic studies(EP) and radiofrequency catheter ablation(RFCA).The pre-excitation zone was determined as a zone of maximum acceleration with “DTI acceleration mode” at the time of the delta wave or before the onset of the QRS complex.At the same time,the contraction velocity was measured from subendocardium of corresponding myocardial segment by “pulsed wave Doppler imaging”.Results Assuming the results of EP and RFCA as a gold standard,the correct localization by DTI was 80% but was only 47.5% and 52.5% by eletrocardiographic algorithms( P

Objective To study the prognosis significance of intratumoral microvascular density(IMD)and the expression of vascular endothelial growth factor(VEGF)in malignant mesothelioma.Methods The data of 79 cases were reviewed of malignant mesothelioma confirmed by histology,immunohistochemistry and telectron microscope.CD34 and the expression of VEGF were detected by Immunohistochemical method.Results The age of the patients with malignant mesothelioma ranged from 11 to 79 years.The peak incidence of malignant mesothelioma was at the range of 40-50 years.The sex ratio of male to female was 1.78∶1.The survival period of the 79 cases was between 5 and 160 months with the medial survival of 23 months.According to histological structure,these cases were divided into epithelioid type(51 cases),sarcomatous type(20 cases)and mixed type(8 cases).For the VEGF positive expression,epithelioid type was 26 cases(50.98%),sarcomatous type was 13 cases(65.00)and mixed type was 5 cases(62.50%).Based on the mean IMD,the patients with malignant mesothelioma were divided into two groups.The survival time of the patients in the higher IMD group was significantly shorter than those in the lower IMD group.The analysis,on the relation of VEGF expression to IMD,as well as survival time and histological subtype,showed that VEGF expression was positively correlated to IMD(P=0.02,r=0.330 2).A significant difference existed between the survival of VEGF positive expression and negative expression(P0.05).Conclusion The results suggest that the prognosis of malignant mesothelioma probably related with IMD and VEGF expression.The higher index of IMD and the higher expression of VEGF might imply a worse prognosis.

Objective To analyze the related factors of relapse of leukemia after transplantation of nonmyeloablative allogeneic hematopoietic stem cells. Methods Among the twenty-nine patients with acute leukemia who received transplantation of nonmyeloablative allogeneic peripheral blood stem cells, relapse of leukemia occurred in 5 patients. The nonmyeloablative protocol included the pretreatment of CD3 monoclonal antibody, cyclosporine A, cyclophosphamide, cytarabine, and fludarabine was added in 3 patients. Results All the 5 patients went through smoothly the hematopoietic suppression stage, and engraftment of the donor cells was successful. Leukemia relapsed in 4 patients with full donor chimerism (full donor chimerism was converted from the mixed chimerism in 2 patients), and relapse occurred in 1 patient with stable mixed chimerism. Except for 1 patient, all of them did not show acute GVHD or chronic GVHD. Second complete remission after double transplant was achieved in one patient, but leakemia relapsed in two months. In other four patients treatment was given up. Conclusion Transplantation of nonmyeloablative allogeneic peripheral blood stem cells is a safe and effective method for the treatment of acute leukemia.

Objective To investigate the clinicopathological change in primary rhabdomyosarcoma of the ear, and its differential diagnosis with infantile rhabdomyosarcoma, primary neuro-ectodermoma, and malignant rhabdomyoma. Methods Gross and microscopic examination and immunohistochemical staining were performed in 8 cases of primary rhabdomyosarcoma of ear. Results Seven male and one female patients with mean age of 7.4 years were found. The tumor was diagnosed as embryonal rhabdomyosarcoma in 7 patients, and botryoid rhabdomyosarcoma in 1 patient. Immunostaining revealed that vimentin and myoglobin were 100% positive, desmin in 75% and actin in 82%. Conclusions Although the histological appearance of primary ear rhabdomyosarcoma does not differ from those found in other soft tissues, its clinicopathological diagnosis may be difficult in some cases, and further immunohistochemical analyses, may be necessary for a correct diagnosis. Its differential diagnosis includes infantile rhabdomyofibrosarcoma, primary neuroectodermal tumor and malignant rhabdoid tumor.
