Objective To investigate the genetic susceptibility to inflammatory bowel disease in China.Methods The pedigree of 5 probands with inflammatory bowel disease (2 with Crohn's disease and 3 with ulcerative colitis) were analyzed including familial history,clinical features,radiographic,endoscopic and pathological findings.A detailed family pedigree and information of the whereabouts of each relative were obtained.Results Crohn's disease was found in 2 families,each with two affected patients (two brothers or mother and a child).Ulcerative colitis was i'ound in 3 families,each with two or more affected patients (an elder sister and younger brother in the first family,mother and a child in the second family and grandparent and 2 grandchildren in the third family ).First-degree relatives were susceptibility to inflammatory bowel disease and siblings were affected more frequently.The member of the later generation was younger at diagnosis than the preceding generation. Offsprings had an earlier onset and more severe than affected parents. A high concordance for type and localization was found between males and females.Conclusions The patients with inflammatory bowel disease have genetic susceptibility and a few member may affect.It may result from multigene or autosomal recessive inheritance.

Objective To analyze the seroprevalence of Helicobacter pylori (H. pylori) infection and its specific genes in liver tissues of chronic hepatitis B virus (HBV) infected patients, and to investigate the effect of H. pylori on development of chronic HBV infected liver diseases. Methods Five hundred and two patients infected with HBV and 429 sex-and age matched healthy controls were enrolled in the case-control study. All subjects were tested for presence of antibodies against H. pylori using ELISA. Fifty-six liver biopsy samples were amplified by polymerase chain reaction (PCR) using Helicobacter genus-specific 16S rRNA primers. The positive samples were further amplified using specific primers of H. pylori cagA, vacA and glmM genes. Results H. pylori infection was accounted for 63.9% in HBV infected patients, which was higher than that in healthy controls (43.4%,P<0.05). Moreover, the seroprevalence of H. pylori in patients with hepatocellular carcinoma (HCC, 29/36,80.6%) or cirrhosis (64/83,77.1%) was higher than that in patients with chronic hepatitis (228/383,59.5%, P<0.01). Helicobacter genus-specific 16S rRNA was found in 17,7 or 11 of patients with cirrhosis, HCC or chronic hepatitis. Twenty-one samples were confirmed as H. pylori DNA by PCR. Conclusions The seroprevalence of antibody against H. pylori was higherHelicobacter can be detected in liver tissues of HBV infected patients. H. pylori might play the role in the development in HBV infected patients compared with healthy controls. Besides H. pylori, other of chronic hepatitis to cirrhosis and HCC.

Objective To investigate the potential effects of Lactobacillus acidophilus strain L6 on prevention and treatment of Helicobacter pylori (H. pylori) infection in animal models. Methods A total of 200 hundred C57BL/6 mice were used in the study. ① Sixty mice were divided into control group (infected with H. pylori) and prevention group (previously treated with L6 and followed by infection with H. pylori) with 30 each. The incidence of H. pylori infection was compared between two groups.② Sixty mice were divided into control group (infected with H. pylori) and treatment group (infected with H. pylori for 4 weeks and followed by treatment with L6) with 30 each. Thechanges of H. pylori infection was compared between tow groups. ③ Eighty mice previously infected with H. pylori were orally administrated with L6 in the water supply over a period of 9 months. Of which, 40 H. pylori negative mice were either continuously or discontinuously treated with L6. The re-infection of H. pylori was compared between two groups. The H. pylori infection, gastric mucosal inflammatory and serum anti-H. pylori-lgG titer was measured by using urea breath test, histopathology and ELISA, respectively. Results The positive rate of H. pylori infection was 100% in control group and 20% in prevention group (pre-treated with L6 for 1 week). Whereas there was no H. pylori infection in the rest mice of prevention group pre-treated with L6 for 2 or 4 weeks. There was significant difference in H. pylori infection between two groups (P<0. 05).The serum anti-H. pylori IgG titer was lower in treatment group than in control group (P<0. 05).The reinfection of H. pylori in mice continuously treated with L6 was significantly lower than those discontiously treated with L6 (P<0. 05). Conclusions Preventively feeding L6 can significantly reduce the H. pylori infection in C57BL/6 mice, whereas the inhibition of H. pylori re-infection can also be achieved with long-term administration of L6.

Objective To observe the efficacy of cumulative dose of polyethylene glycol-interferon (Peg-IFN)α-2a combined with ribavirin in patients with decompensated hepatitis C virus (HCV)-related liver cirrhosis , and to evaluate the effects of anti-virus therapy on the progress of the disease . Methods From January 2005 to March 2009 ,patients with decompensated HCV-related liver cirrhosis were enrolled ,also included patients received partial splenic embolization .Peg-IFNα-2a combined with ribavirin therapy was given to patients whose blood cell met interferon (IFN) therapy standards .The dosage of Peg-IFNα-2a and ribavirin was adjusted according to the tolerance of the patients .After the treatment ,the patients were followed-up for 24 weeks .The patients whose blood cell did not meet IFN therapy standards and the patients unwilling to receive anti-virus therapy were assigned to control group and were followed-up for 96 weeks .The total amount of medication was calculated according to cumulative exposure dose . Sustained virological response (SVR ) , recurrence rate , liver function and disease progression were observed .The t test or Chi-square test was performed for comparison between groups and rate of disease progression was analyzed with Kaplan Meier curve .Results After anti-virus therapy , SVRs of patients with cumulative dose of Peg-IFNα-2a and ribavirin over 60% (include 60% ) were 27 .3%(12/44) and 27 .7% (13/47) ,respectively ;the recurrence rates were 7/19 and 35 .0% (7/20) ,respectively . In patients with cumulative dose less than 60% ,SVRs were 1/7 and 1/4 ,respectively ,and the recurrence rates were both 1/2 ;the differences of different doses was not statistically significant (all P>0 .05) .At the 24th week of follow-up after therapy ,the Child-Pugh score of combined therapy group was 7 .9 ± 1 .4 , which was lower than that before treatment (8 .5 ± 1 .2) ,and the difference was statistically significant (t=2 .33 ,P=0 .02) .At the 96th week of follow-up ,the Child-Pugh score of control group was 10 .0 ± 1 .6 ,which was higher than that before treatment (8 .5 ± 1 .4) ,and the difference was statistically significant (t=5 .82 , P<0 .01) .The disease progression rate of combined therapy group was 15 .7% , which was lower than that of control group (32 .4% ) ,and the difference was statistically significant (χ2=4 .34 ,P= 0 .04) .Conclusion The application of non-standard dosage of Peg-IFNα-2a combined with ribavirin in the patients with decompensated HCV-related liver cirrhosis can achieve virological response once the cumulative dose reached certain standards ,improve Child-Pugh scores of patients and slow disease progression .

Objective To compare the Helicobacter pylori (Hp) eradication rate of different therapies and to explore the effects of Hp eradication on the clinical characteristics of chronic obstructive pulmonary disease (COPD).Methods From December 2006 to December 2009,at China-Japan Union Hospital of Jilin University 89 stable COPD patients with Hp infection were divided into eradication group and non-eradication group.The eradication group was divided into clarithromycin sub group and moxifloxacin sub group.The patients of these three groups all received regular COPD treatment.Esomeprazole,amoxicillin,clarithromycin and colloidal bismuth citrate were used in clarithromycin group.Esomeprazole,amoxicillin,moxifloxacin and colloidal bismuth citrate were used in moxifloxacin sub group.Patients received pulmonary function test,exercise tolerance evaluation,dyspnea scoring and health-related quality of life scoring at recruitment and 12 months after recruitment.The onset frequenly of acute exacerbation of COPD in one year was counted.The data were analyzed by x2 test and t test.Results The Hp eradication rate of clarithromycin sub group (48.4 ％,15/31) was lower than that of moxifloxacin sub group (87.1％,27/31),and the difference was statistically significant (x2 =4.22,P=0.032).There was no significant difference percentage of forced expiratory volume in first second to forced vital capacity in (FEV1％) predicted value between 27 cases in non-eradication group and 53 patients with successful Hp eradication (t=0.677,P=0.265).Of 53 patients with successful Hp eradication,the 6-min walking distance,Borg dyspnea score and saint George's respiratory questionnaire (SGRQ) score were improved significantly (t =1.884,1.877 and 1.773 respectively; P=0.032,0.025 and 0.034 respectively),and there was no improvement in 27 non-eradication patients.There was significant difference in the frequency of COPD acute attack between 53 patients with successful Hp eradication (1.2 times) and non-eradication group (1.9 times) (t=1.812,P =0.034).Conclusions Hp eradication therapy with moxifloxacin in COPD patients reached higher Hp eradication rate.Hp eradication in COPD patients with Hp infection can improve the exercise tolerance of patients,relieve dyspnea,improve quality of life and reduce the frenquency of acute attacks.

Objective To investigate the prevalence of Helicobacter hepaticus (H. hepaticus)infection in various species of mice from different regions of China in order to find the role of H. hepaticus in development of hepatitis, liver cancer and tumors in lower digestive tract in mice.Methods One hundred and fourteen mice, including C57BL/6 mice (n= 39), BABL/C mice (n=45),SCID mice (n=14) and C3H mice (n=18), were collected from different regions of China. The serum anti-H, hepaticus-IgG and fecal H. hepaticus antigen were determined by using ELISA. Polymerase chain reaction analysis (PCR) was used to screen Helicobacter genus-specific 16SrRNA and H. hepaticus species-specific 16SrRNA. The feces were cultured and identitied for Helicobacter infection in 114 mice. The H. he paticus infection was identified as one of above tests being positive.Results Of 114 mice, 25 (21.9%) mice were infected with Helicobacter species. The mice infected with H. hepaticus accounted for 44. 0% (11/25) with SCID and C3H mice in high prevelence.Meanwhile, the PCR examination revealed that the rest 56.0% (14/25) mice were infected with other Helicobacter species. Conclusion Besides H. hepaticus infection, the other Helicobacter species infections are also existed in China.
