Abstract:
Objective To investigate the association between MYO9B rs962917 and rs1545620 gene polymorphism and clinical pathological characteristics of patients with inflammatory bowel disease (IBD) and permeability of intestinal mucosa.Methods From September 2010 to May 2012,a total of 196 cases of patients with IBD were collected,100 cases were ulcerative colitis (UC) and 96 cases were Crohn's disease (CD).At the same time,99 gender and age matched healthy individuals were collected as healthy controls.The 5 mL blood of participants was obtained and DNA was extracted.The MYO9B gene rs962917 and rs1545620 polymorphism was detected by polymerase chain reaction (PCR) and ligase detection reaction (LDR).After 60 patients with UC and 58 patients with CD orally took intestinal permeability testing fluid (with lactulose and mannitol),the urine of the patients was analyzed with high pressure liquid chromatography-pulsed lectrochemical dection (HPLC-PED).The permeability of intestinal mucosa was determined according to the ratio of lactulose and mannitol.Chisquare test was used for count data.Results Compared with healthy control group,there was no significant difference in genotype and allelic gene distribution of MYO9B rs962917 and rs1545620 of IBD group,UC group and CD group (all P>0.05).The genotype of MYO9B rs962917 and rs1545620 of patients with UC was not related with the disease activity and location of lesions (rs962917:x2 =0.481 and 3.812,rs1545620..x2 =0.398 and 4.543 ;all P>0.05).The genotype of MYO9B rs962917 of patients with CD was not related with the disease activity,lesion type and occurrence of perianal lesions (x2 =0.384,0.476 and 3.486,all P>0.05) and was related with location of lesions (x2=15.926,P<0.05).The genotype of MYO9B rs1545620 of patients with CD was not related with the disease activity and lesion type (x2 =1.407 and 5.126,both P>0.05),however was related with location of lesions and occurrence of perianal lesions (x2 =18.165 and 7.629,both P<0.05).The permeability of intestinal mucosa of all 58 patients with CD was high.The genotype of MYO9B rs962917 and rs1545620 of patients with UC was not related with the permeability of intestinal mucosa (x2=1.508 and 1.025,both P > 0.05).Conclusion MYO9B rs962917 and rs1545620 gene polymorphism is related with the location of lesions in CD and is not related with the permeability of intestinal mucosa of patients with UC.
