Objective: To investigate the role of intraoperative ultrasound(IOUS) and appropriate approach in local resection for the central small hepatocellular carcinoma(sHCC) which is deeply situated within the parenchyma and adjacent to the hepatic veins. Methods: under IOUS guidance, local resection was carried out for 8 cirrhotic patients with central sHCC which was deeply located and adjacent to hepatic veins by approach of splitting or unroofing superficial hepatic parenchyma. Results: All tumors were precisely localized by IOUS and excised successfully. Except for injury to central hepatic vein in 1 case, no other injury occurred to the hepatic veins in the remaining 7 cases. There was no postoperative mortality, and the liver function recovered well in all cases postoperatively. Conclusion: Local resection by using IOUS and appropriate approach is applicable for the cirrhotic patients with deeply located central sHCC. IOUS plays an important role in avoidance of injuries to the hepatic veins.

The mitogen-actived protein kinase(MAPK)is one of important ways in eukaryote signal transmission network,and plays the key role in the gene expression regulation and the cytoplasm function activity.In the mammal organism,five kinds of different MAPK signal transduction passage.ERK1/2 signal transduction passage regulates cell growth and differentiation,JNK and p38 MAPK signal transduction passages play the vital role in the stress of inflammation and apoptosis etc.The activation of signal transduction passage is the typical characteristic of RA chronic synovitis,through this way to induct synoviocytes cytoplasm protein phosphorylation,then causes transcription factor and nucleoprotein c-Fos,c-Jun,AP-1 and NF-kappa B and so on phosphorylation,thus promotes cell proliferation and activation.It has the vital significance of the above-mentioned mechanism research to understand deeply and researche new medicine to RA.

Objective Atrophic gastritis, as a pre-cancerous condition of gastric cancer, is developed from non-atrophic gastritis.The aims of this study was to compare the gene expression profiles between atrophic gastritis and non-atrophic gastritis using cDNA microarray and to explore the molecular mechanisms in the development of atrophic gastritis. Methods Endoscopy and biopsy were performed consecutively in 227 patients (143 male, 84 female, age range between 16-72 years, with average age 48.6 years). Diagnosis of non-atrophic gastritis and atrophic gastritis was made according to histological examination, and 120 patients were in non-atrophic group and 107 in atrophic group. The total RNA was extracted from the biopsy specimens of two groups with Trizol reagent. cDNA microarray consisting 8 464 human genes (HGEC-80s kit) was used, and labeled cDNA with fluorescence probes were hybridized to microarray, and then the comparison of gene expression profiles was made between atrophic and non-atrophic gastritis. Results It was identified that in gene expression profiles of atrophic gastritis there were 165 genes showing a greater than 2-fold increase and 460 genes showing a greater than 50% decrease as compared to non-atrophic gastritis. RT-PCR analysis revealed similar results as in DNA microarray. Conclusions There is different expression in many genes between the gastric mucosal cells of non-atrophic and atrophic gastritis mucosa. Many genes expression profiles are involved in atrophic gastritis that would be of help in further understanding the development of atrophic gastritis.

OBJECTIVE:To study the protective effect of tanshinoneⅡA(TSⅡA)sulfonate injection against vancomycin(VAN)-induced renal injury model rats and its mechanism. METHODS:72 rats were randomly divided into blank group,model group, positive control group(amifostine,1 mg/kg)and TSⅡA sulfonate injection low-dose,medium-dose and high-dose groups(15,30, 60 μg/kg),with 12 rats in each group. Except for blank group,those groups were given VAN(200 mg/kg)intravenously via tail vein to induce renal injury rat model;after modeling,each drug group was given relevant medicine intraperitoneally once a day, and blank group and model group were given normal saline intragastrically for consecutive 10 days. The levels of 24 h protein, NAG and KIM-1 in urine were determined,and those of Cys C,Scr and BUN in serum and those of SOD,MDA,GSH-Px and NO in renal homogenate were also determined;the pathological change of renal tissue was observed. RESULTS:Compared with blank group,the levels of Cys C,Scr and BUN in serum,those of 24 h protein,NAG and KIM-1 in urine and those of MDA and NO in renal tissue increased significantly in model group,while the levels of SOD and GSH-Px decreased significantly(P<0.01);the pathological slice indicated that model group suffered from renal injury such as kidney tubules albuminoid degeneration,brush border abscission,renal tubular epithelial cell disintegration and abscission. Compared with model group,the levels of Cys C,Scr and BUN in serum,those of 24 h protein,NAG and KIM-1 in urine and those of MDA and NO in renal tissue decreased signifi-cantly in treatment groups,while the levels of SOD and GSH-Px in renal tissue increased significantly(P<0.05 or P<0.01);path-ological changes of renal tissue were relieved significantly. CONCLUSIONS:TSⅡ A sulfonate injection can effectively relieve VAN-induced renal injury in rats,and its mechanism may be associated with inhibiting the oxidative reaction of rats in vivo.
