Objective To investigate the effect of low-dose hydrocortisone(HC)on hippocampus nuclear factor kappa B((NF-?B)),I?B expression in lipopolysaccharide(LPS)induced septic rats and the role of NF-?B signal transcription pathway in pathogenesis.Methods Fifty-four rats were randomly divided into 3 groups: control group(A group,n=6),model group(B group,n=24),low-dose HC treatment group(C group,n=24).The septic rat model was established by intraperitoneal injection LPS(1 mg/kg),as the intervention by caudal vein injection low-dose HC(6 mg/kg),each of B and C group was subdivied into 2,8,16,24 hours respectively after LPS injection(n=6).At serial time points,the animals in each group were sacrificed,brain tissue samples were harvested to determine NF-?B,I?B expression by immunhistochemistry in hippocampus.Results In B group: NF-?B expression was up regulated compared with A group(P

In order to cultivate advanced person with ability,we should teach students some theoretics and more practical skill during microbiology teaching. after we using the measures “examining on theoretics and practical skill that must be mastering in the lesson”. Students had been more interested in microbiology,and advanced of knowledge. So “examining on theoretics and practical skill that must be mastering in the lesson” is better method in teaching of Microbiology in Occupation technique college.

Introduction:Transcatheter arterial chemoembolization (TACE) plus thermal ablation has been widely used recently in the treatment of hepatocellular carcinoma (HCC). In this study, we aimed to compare results of the combination of TACE and percutaneous thermal ablation with those of hepatectomy in patients with HCC. Methods:The clinical data of 137 HCC patients who sequentially received TACE and computed tomography (CT)-guided percutaneous thermal ablation as an initial curative treatment (combination group) and 148 matched HCC patients who received hepatectomy (surgery group) between 2004 and 2011 were collected and analyzed. After TACE, multiphase contrast-enhanced CT was performed to identify the total number of tumors as well as lipiodol deposition in the liver. Survival was calculated by using the Kaplan-Meier method and compared by using the log-rank test. The prognostic factors were assessed with multivariate Cox proportional hazards regression analysis. Results:Of all 285 patients, 225 (79.0%) had cancerous lesions≤5 cm in diameter. In preoperative contrast-enhanced CT or magnetic resonance imaging, the number of tumors was 1–4 for each patient. The 1-, 3-, and 5-year overal survival rates were 95, 74%, and 67%in the combination group and 88, 66, and 47%in the surgery group, respectively (P=0.004);the corresponding recurrence-free survival rates for the two groups were 92, 69, and 61%and 75, 58, and 44%, respectively (P=0.001). In the multivariate analysis, treatment al ocation was an independent prognostic factor for survival. Only 60 patients in the combination group had sufficient imaging data, and 135 new lesions with lipiodol deposition were diagnosed as malignancies in 22 of 60 patients, whereas 20 new lesions were found in 11 of 148 patients in the surgery group. Conclusion:The combination of TACE and CT-guided percutaneous thermal ablation for HCC improves survival of HCC patients compared with hepatectomy.

Objective: To analyze the CYP2C19 gene polymorphism in patients with upper digestive system diseases in Anhui Province, so as to provide evidence for individual treatment. Methods: The 307 patients with upper digestive system diseases in the Department of Gastroenterology, The 901st Hospital of Combined Service Force of People＇s Liberation Army were selected. The CYP2C19 genotypes were detected by DNA microarray microarray. The CYP2C19 genotypes and metabolic types in different genders, ages and diseases were analyzed. Results: There were 197 males ( 64.17% ) and 110 females ( 35.83% ) , with the age of ( 58.00±16.13 ) years old. The gene frequency of CYP2C19*1, CYP2C19*2 and CYP2C19*3 was 62.70%, 32.25% and 5.05%, respectively. There were 119 cases (38.76%) of *1/*1 ( 636GG, 681GG ), 129 cases ( 42.02% ) of *1/*2 ( 636GG, 681GA ) , 18 cases (5.86%) of *1/*3 ( 636GA, 681GG ) , 29 cases ( 9.45% ) of *2/*2 ( 636GG, 681AA ) , 11 cases ( 3.58% ) of *2/*3 ( 636GA, 681GA ) , and 1 cases ( 0.33% ) of *3/*3 ( 636AA, 681GG ). In terms of metabolisms, there were 119 cases ( 38.76% ) of fast metabolism type, 147 cases (47.88%) of intermediate metabolism type and 41 cases (13.35%) of slow metabolism type. There were no significant differences in CYP2C19 genotypes and metabolic types among the patients with different gender, age and digestive system diseases ( P＞0.05 ). Conclusion The CYP2C19 genotypes of patients with upper digestive system diseases were polymorphic, mainly the fast metabolism type and the intermediate metabolism type, which could provide reference for the clinical medication of individualized treatment of proton pump inhibitors.

Hemangiomas in the pancreas are very rare and only a few cases in adulthood have been reported in the literature. We describe a case of pancreatic hemangiomas in an adult with unique imaging findings. A 23-year-old woman visited the hospital for an incidentally detected pancreatic mass. CT and MRI revealed a multilocular cyst with fluid-fluid levels and no obvious enhancement. The patient underwent surgery and the mass was confirmed as a pancreatic hemangioma. The radiological features and differential diagnosis of this rare lesion are discussed.

Objective To study the function of core protein (CORE) of genotype 1b hepatitis C virus (HCV) of different strains (T: derived from tumor tissues; NT: derived from non-tumor tissues; C191: HCV-J6) and different domains (1-172, 1-126, 1-58, 59-126, 127-172 AA) of T CORE in the pathogenesis of HCV infection and to find the therapy target. Methods Different truncated genotype 1b HCV CORE eukaryotic expression plasmids (T, NT, C191) and different domains of T CORE were constructed and transfected to HepG2 cells. Cell apoptosis and necrosis were quantified by flow cytometry. Cell growth curves were observed with real time cell growth instrument. Results COREs from different strains of genotype 1b and different domains of CORE induced cell apoptosis and necrosis, and inhibited HepG2 cell growth at different levels. CORE derived from T induced apoptosis and necrosis and inhibited cell growth higher than that derived NT and C191. N terminal 1-58 AA of CORE derived from T induced cell apoptosis and necrosis and inhibited cell growth higher than any other domains. Conclusion COREs from different strains of genotype 1b HCV and different domains of CORE from the same HCV strain play different roles in their molecular pathogenesis of HCV. Among different domains of CORE, N terminal 1-58 AA might play an important role in its pathogenesis and be one target of gene therapy.

Objective To study the influence of electro-acupuncture(EA)at Zusanli points(足三里穴) on the apoptosis of thymocytes in rats with abdominal infection and its mechanism.Methods A total of 40 Sprague-Dawley(SD)rats were randomly divided into four groups,including normal control group,model group,non-acupoint group and Zusanli group.The abdominal infection model of rat was made by cecal ligation and puncture(CLP).After abdominal cavity infection for 36 hours,the apoptosis of thymocytes was observed under electron microscope and light microscope,and the apoptosis ratio of thymocytes was determined by Annexin V-PI method with flow cytometry technique.The content of Bcl-2 protein of thymocytes and concentration of corticosterone in plasma were determined.Results Abdominal infection resulted from CLP could significantly increase the apoptosis of thymocytes and lead to the typical histopathological changes of apoptosis of thymocytes under electron microscope and light microscope.Apoptosis ratios of thyrnocytes in model group[(44.7?3.3)%],non-acupoint group[(42.7?3.0)%]and Zusanli group[(32.6?3.3)%] were significantly higher than the ratio in the control group[(21.2?2.3)%,all P0.05).Abdominal infection resulted from CLP also could reduce the content of Bcl-2 protein of thymocytes.The content of Bcl-2 protein of thymocytes in model group(71.2?5.6),non-acupoint group(73.5?5.9)and Zusanli group(82.4?6.8) were significantly lower than normal control group(95.3?6.3,all P
