ABSTRACT
In this study ,we aimed to understand the sequence characteristics ,transmembrane structures ,line B cell epitopes present in the OMP18 from Campylobacter jejuni ,and provide candidate antigens for the antibody detection and vac-cine development .NCBI/Blast ,TMHMM Server V2 and DNA Star softwares were used for the OMP18 sequence analysis . Based on the ELISA ,the whole bacterial antibody IgG of Campylobacter jejuni was used for the identification of the predicted line B cell epitopes .The OMP18 gene was found conserved in different Campylobacter jejuni strains .The OMP18 was predic-ted to be located on the outer surface of the bacteria .And three line B cell epitopes were determined to be present in the OMP18 protein .As a conclusion ,the OMP18 protein was confirmed to be an important outer membrane protein ;three line B cell epitopes were identified in the OMP18 ,which could be further used for Campylobacter jejuni antibody detection and vaccine development .
ABSTRACT
Objective To investigate the diagnostic value of one-stop liver magnetic resonance dynamic enhanced MRA for esophageal and gastric varces.Methods 82 patients with liver cirrhosis portal hypertension who were diagnosed by clinical and laboratory detect were taken,conducting liver horizontal scanning and multitemporal three dimensional dynamic enhanced scanning using Philips Achieva 1.5T MRI scanner,and then make maximum intensity projection(MIP) at work station to draw up portal vein image,observing the form and distribution of portal vein and its branches,meanwhile refer to cross sectional image to carefully observe whether there was cirsoid vein in esophagus and stomach,and further the source,degree and depth of cirsoid vein were compared,and whether there was cirsoid vein in other parts,and the pathological situation of liver.Compared with the result of gastroscope inspection,whether there is cirsoid vein in esophagus and stomach.Results The trunk and class-Ⅲ branches of portal vein of all patients had been clearly shown.In this team,there were esophageal and gastric varces in 78 patients,specifically including varices of fundus of stomach & esophageal varices in 27 patients,and varices of fundus of stomach and varices of body of stomach in 19 patients.Meanwhile,it diagnose 6 patients with liver cirrhosis and liver cancer and indicate 8 patients with liver cirrhosis nodule cancerization.The endoscope found out esophageal varices and varices of fundus of stomach in 68 patients,specifically including gastric varicesa and esophageal varices in 25 patients,sole gastric varicesa in 8 patients,and sole esophageal varices in 35 patients.Conclusion The one-stop liver three dimensional dynamic enhanced MRA is with great value in diagnosing the location and degree of esophageal varices and varices of fundus of stomach of patients with portal hypertension.The overall effect is better than endoscope.
ABSTRACT
<p><b>OBJECTIVE</b>To make a study of the influence of the intervene of traditional Chinese medicine on cytokine level in benign prostatic hyperplasia.</p><p><b>METHOD</b>The patients were divided into treatment group (group A), control group (group B) and healthy group (group C) with the randomly compared researching method. Group A were given Qianliening Tang (QLNT), daily potion, two times a day. Group B were given Qianliekang, three times a day, three pills each time. The course of both treatment lasted for 8 weeks.</p><p><b>RESULT</b>Before treatment, TNF-alpha, IL-17/IL-10, IL-4 in group A and B are obviously out of order compared with group C (P < 0.01). After the treatment, TNF-alpha, IL-17 in group A decreased dramatically and IL-10, IL-4 increased, which shows great differences compared with those before treatment and with group B (P < 0.01), but still can't reach to group C level.</p><p><b>CONCLUSION</b>Qian liening Tang can efficiently regulate the level of suppressive inflammatory cytokines and proinflammatory cytokines. It provides scientific experimental basis for clinical diagnosis and treatment of the disease.</p>
