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.

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.

AIM To establish an HPLC-ELSD method for the simultaneous content determination of gastrodin,parishin A,parishin B,ginsenosides Rg1,Re,Rf,Rb1 and Rd in Tiantai No.1 Tablets (Ginseng Radix et Rhizoma,Gastrodiae Rhizoma,Cistanches Herba,etc.).METHODS The analysis of methanol extract of this drug was performed on a 45 ℃C thermostatic Alltima C1scolumn (4.6 mm × 250 mm,5 μm),with the mobile phase comprising of acetonitrie-0.1％ phosphoric acid flowing at 1.0 mL/min in a gradient elution manner.RESULTS Eight constituents showed good linear relationships within their own ranges (r ＞ 0.999 0),whose average recoveries were 96.94％-97.93％ with the RSDs of 1.06％-2.48％.CONCLUSION This simple,accurate and reliable method can be used for the quality control of Tiantai No.1 Tablets.

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.
