Nco Ⅰ and AspH Ⅰ gene polymorphisms.H.pylori infection status was determined by a validated serological test.Results:H.pylori infection was detected in 90.5% of 210 patients and 62.1% of 264 healthy controls(P

Forty patients with hypertension suspected to stenosis of renal artery were selected from Department of Cardiology, General Hospital of Chinese PLA between June 2007 and March 2008, including 28 males and 12 females with an average age of (60.0?15.6). Capoten test and renal artery angioplasty were performed in all patients to detect brain natriuretic peptide changes before and after the Capoten test and renal artery stent implantation. Among 40 patients underwent Capoten test, 30 showed positive result and 10 negative. The levels of brain natriuretic peptide before and after Capoten test in patients with positive result were statistically different (P 0.05). Among thirty patients with positive Capoten test undergoing renal artery angioplasty, twenty-three patients underwent stent implantation, and their brain natriuretic peptide showed statistical differences between before and after stent implantation (P 0.05). The results of the study show that levels of brain natriuretic peptide can be used to evaluate possible effect of stent implantation for patients with hypertension suspected to stenosis of renal artery.

Objective To screen the plasma differential expressed proteins in patients with Crohn's disease(CD)and ulcerative colitis(UC)using surface-enhanced laser desorption ionizationtime of flight mass spectrometry,and to establish decision trees algorithms.Methods The plasma samples from 24 UC patients,25 CD patients and 25 healthy controls were analyzed with CM10 protein chip.The proteomic spectra of CD,UC and inflammatory bowel disease(IBD)were compared with controls respectively.The differential proteins that significantly altered expression levels were selected to establish decision trees algorithms of CD.UC and IBD and then blind validations were tested.Results In the range of m/z 2000-30 000,differential expressed proteins that changed at least 2-fold between CD and controls were 9.between UC and controls were 5,and between IBD and controls were 11(P＜0.05).The software automatically picked up the m/z 8208 and 8837 as decision trees algorithms for differentiating CD from controls and m/z 6985 for differentiating UC from controls as well as m/z 8208,1752,28840 and 1702 for differentiating IBD from controls.The sensitivities of decision trees algorithms for CD,UC and IBD were 96%,82%and 91%respectively,and the specificities were 100%,85%and 100%respectively.Conclusions The protein of m/z 8208 which has high sensitivity in differentiating CD from controls is worthy of further study.

Background Most anti-inflammation eyedrops are limited in clinical application owing to multiple adverse effects.A novel peptide GC31 derived from human thrombomodulin has a natural anti-inflammatory activity.Compared with conventional anti-inflammatory eyedrops,GC31 possesses more advantages and potential clinical transforming value.However,relevant study is still lack.Objective The purpose of this study was to evaluate the anti-inflammatory effect of GC31 and the possible mechanisms.Methods Sixty SPF male Wistar rats aged 8-10 weeks were randomized into 6 groups using randomized number table.Non-specific keratitis models were established in 40 rats by intrastromal injection of 10 μl of lipopolysaccharide (LPS) dissolved in PBS.Different doses of GC31 (125 μg or 250 μg) or dexamethason soluble in PBS were sunconjunctically injected in the experimental eyes respectively in the low dose GC31 group,high dose of GC31 group and the dexamethason group,and 10 μl of PBS was used in the same way in the PBS control group.No drug was injected in the model group,and the normal rats were employed as the blank control group.The corneas were examined by slit lamp microscope and were scored based on the criteria of Anand 24 hours after injection.Then the corneas were collected for histopathological examination.Expression of nuclear factor-κB (NF-κB) p65 in the corneas was detected using immunochemistry.Expressions of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) proteins were assayed using ELISA.Real-time PCR was used to detect the expressions of IL-6 mRNA and TNF-α mRNA.The use and care of the experimental animals followed Regulation for the Administration of Affair Concerning Experiment animals by State Science and Techonology Commission.Results A significant difference was seen in the ocular inflammatory scores among the six groups (F =301.238,P =0.000).The inflammatory scores were significantly lower in the high dose of GC31 group than those in the model group (1.85 ± 0.36 versus 2.90± 0.43) (t' =-5.144,P =0.000) ; and the scores in the dexamethason group was lower than those in the high dose of GC31 group(t' =-3.931,P=0.000).Infiltration of inflammatory cells in corneal tissue was milder in the high dose of GC31 and the dexamethason group compared with the model group.The positive response for NF-κB p65 was obviously weaker in the rat corneas in the low and high dose of GC31 groups and the dexamethason group in comparison with the model group.The contents of IL-6 and TNF-α proteins in the corneas were significantly reduced in the low and high dose of GC31 group and the dexamethason group compared with the model group (low dose group:t=-2.626,P=0.009;t'=-2.310,P=0.017.high dose group:t =-3.361,P=0.001 ;t'=-3.151,P=0.002),and the contents of IL-6 and TNF-α proteins in the dexamethason group were lower than those in the high dose of GC31 group (t=-3.361,P=0.001;t'=-3.360,P=0.000).In addition,the expression trend and compared results of IL-6 mRNA and TNF-α mRNA among the groups were similar to those of the IL-6 and TNF-α proteins (all at P＜0.01).Conclusions GC31 suppresses LPS-induced corneal inflammation response by downregulating the expression of inflammatory eytokines.The effect is more dominant in the doses of 250 μg than that in the doses of 125 μg.

Objective To investigate human immunodeficiency virus type 1 (HIV 1)specific CD8'T cell responses and related human leukocyte antigenⅠ(HLA-I)restriction sites.Methods Four Epstein-Barr virus (EBV)strains-transformed B-lymphoblastoid cell lines (BLCL)from periph eral blood monocytes (PBMC)of 4 healthy individuals were established.Using synthesized peptides in HIV-1 Gag,Vif and Nef regions as epitopes and using BLCL as antigen presenting cells (APC), the frequency of interferon-7(IFN-?)secreting cells in CD8 T cells from a HIV-infected long term nonprogressor by enzyme-linked immunospot (ELISPOT)assay in vitro were assessed.Moreover, matching analysis of HI.A-Ⅰrestriction sites were performed.Results HIV-1 epitopes were presen ted restrictively by HLA-Ⅰmolecules in specific CD8 T cell responses,and this antigen presenting had high specificity.HLA-Ⅰrestriction sitesA03,A26,C04andC08 contributed to presentepitopes in HIV-1 C-ag region,A03 and C08 to HIV-1 Nef as well.Conclusion HLA-Ⅰrestriction sites may include A03,A26,C04 and C08 in HIV-1 Gag region,and A03,C08 in Nef region.
