METHODS： Thirty-six gastric ulcer （GU） patients and 29 non-ulcer （NU） patients were enrolled in this study. Mucosal biopsy samples were obtained from the gastric antrum and GU site during endoscopy. Samples were used in in situ stimulation for 48 h in the presence of 10 ug/mL phytohemagglutinin-P （PHA）, histological examination, and Helicobacter pylori（Hpylon） culture. IL-17 and IL-8 protein levels in culture supematants were assayed by ELISA. IL- 17 mRNA expression was analyzed by reverse transcriptasepolymerase chain reaction （RT-PCR）. Hpylori cagA and vacA status was assessed by reverse hybridization using a line probe assay （UPA）. IL-8 levels in culture supematants were assayed after AGS cells were co-cultured with Hpylori strain 26 695 or recombinant human （rh） IL-17. RESULTS： All 36 GU patients and 15 of 29 NU patients were found to be Hpy/or/-positive, while 14 NU patients were Hpylori-nogative. All 51 H pylori strains from both GU and NU patients were cagA- and vacAsl/ml-positive. Antral mucosal tissues from H pylori-positive patients contained significantly （H pylori-positive NU patients： median 467 pg/mg/protein, range 53-2 499; Hpylori negative NU patients： median 104 pg/mg/protein, range 16-312, P〈0.0005） higher levels of IL-17 than those from uninfected patients. IL-17 levels at the ulcer site were significantly （ulcer site： median 1 356 pcj/mg/protein, range 121-1 3730; antrum： median 761 pg/mg/protein, range 24-7 620, P〈0.005） higher than those at distant sites in the antrum. Biopsies from H pylori-positive GU and NU patients showed IL-17 mRNA expression in all samples whereas those from the antrum of the Hpylori-negativecontrols showed no detectable expression. A significant correlation was seen between IL-17 and IL-8 levels at each biopsy site （ulcer： r = 0.62,P〈0.0001; antrum： r = 0.61, P〈0.0001） in GU patients. RhIL-17 and Hpylori strain 26 695 each stimulated IL-8 production from AGS cells. CONCLUSION： IL-17 may play an important role in the inflammatory response to Hpyloricolonization, and may ultimately influence the outcome of H pylori-associated diseases that arise within the context of gastritis.展开更多

METHODS: The study was conducted on 50 Egyptian patients (36 male, 14 female) with hepatitis C virus (HCV) infection, who visited the Hepatology Outpatient Clinic in the Endemic Disease Hospital at Cairo University. Patients were compared with 25 ageand sexmatched healthy individuals. Inclusion criteria were based on a history of liver disease with HCV genotype 4 (HCV-4) infection (as new patients or under followup). Based on ultrasonography, patients were classified into four subgroups; 14 with bright hepatomegaly; 11 with perihepatic fibrosis; 11 with hepatic cirrhosis; and 14 with cirrhosis and hepatocellular carcinoma (HCC).Total Vit D (i.e., 25-OH-Vit D) and active Vit D [i.e., 1,25-(OH) 2 -Vit D] assays were carried out using commercial kits. IL-17, IL-23 and PⅢNP levels were assayed using enzyme linked immunosorbent assay kits, while HCV virus was measured by quantitative and qualitative polymerase chain reaction. RESULTS: Levels of Vit D and its active form were significantly lower in advanced liver disease (hepatic cirrhosis and/or carcinoma) patients, compared to those with bright hepatomegaly and perihepatic fibrosis. IL-17, IL-23 and PⅢNP levels were markedly increased in HCV patients and correlated with the progression of hepatic damage. The decrease in Vit D and active Vit D was concomitant with an increase in viral load, as well as levels of IL-17, IL-23 and PⅢNP among all subgroups of HCV-infected patients, compared to normal healthy controls. A significant negative correlation was evident between active Vit D and each of IL-17, IL-23 and PⅢNP (r = -0.679, -0.801 and -0.920 at P < 0.001, respectively). HCV-infected men and women showed no differences with respect to Vit D levels. The viral load was negatively correlated with Vit D and active Vit D (r = -0.084 and -0.846 at P < 0.001, respectively), and positively correlated with IL-17, IL-23 and PⅢNP (r = 0.951, 0.922 and 0.94 at P < 0.001, respectively). Whether the deficiency in Vit D was related to HCVinduced chronic liver disease or was a predisposing factor for a higher viral load remains to be elucidated. CONCLUSION: The negative correlations between Vit D and IL-17, IL-23 and PⅢNP highlight their involvement in the immune response in patients with HCV-4related liver diseases in Egypt.展开更多

Methods： Forty SPF grade Sprague-Dauley （SD） male rats were randomly divided into a normal group, a model group, an herbal cake-partitioned moxibustion group and a Western medicine group, with 20 rats in each group. Except the normal group, rats in the other three groups were used to make CD model by giving an enema in colon with Trinitro-benzene-sulfonic acid （TNBS）. When the models were successful made, rats in the model group had no therapeutic intervention; rats in the herbal cake-partitioned moxibustion group were subjected to herbal cake-partitioned moxibustion treatment at bilateral Tianshu （ST 25） plus O.ihai （CV 6）; and rats in the Western medicine group were given oral Mesalazine. After treatment, the histopathological changes and inflammatory cytokines IL-17, IL-23 and their mRNAs expressions were observed in descending colon by hematoxylin-eosin （HE） staining, immunohistochemistry （IHC） and real-time polymerase chain reaction （RT-PCR） methods. Results： Colon tissues of TNBS enema rat models showed cracks-like ulcers accompanied by mucous layer inflammation, granulomas, and inflammatory cytokines IL-27, IL-23 and their mRNAs expressions were all higher than those in the normal group （P〈O.01）; after intervention, colon tissue cracks-like ulcers and inflammation degree reduced, inflammatory cytokines IL-17, IL-23 and their mRNAs expressions were all significantly decreased （P〈0.01） in the herbal cake-partitioned moxibustion group and the Western medicine group. Conclusion： Herbal cake-partitioned moxibustion may improve colon tissue ulcers and relieve intestinal inflammation by down-regulation of IL-17, IL-23 and their mRNAs expressions in CD model rats＇ colonic mucosa.展开更多
