The correlation study between miRNA-802 expression and inflammatory response in patients with inflammatory bowel disease / 国际检验医学杂志

Objective To investigate the correlation and significance between miRNA-802 and inflammato-ry factors in the patients with inflammatory bowel disease (IBD) ,and to understand pathologic mechanisms of IBD.Methods 80 patients with active IBD ,who were hospitalized in Department of Gastroenterology ,Taizhou People's Hospital ,from August 2015 to February 2017 ,were selected as active IBD group.Another 40 inactive IBD patients and 40 healthy persons who underwent the healthy assessment during the same period were se-lected as inactive IBD group and healthy control group.The expression level of miRNA-802 in intestinal muco-sa and peripheral blood mononuclear cells of each group was detected by fluorescence quantitative PCR (RT-qPCR).In addition ,the relative expression of miRNA-802 in the intestinal mucosa and peripheral blood mono-nuclear cells of 43 patients with Crohn's disease (CD) treated by IFX (IFX) was detected and the correlation with the serum TNF-α was analyzed.Results The expression level of miRNA-802 in the intestinal mucosa and peripheral blood mononuclear cells of active IBD patients was significantly higher than that of inactive IBD pa-tients and healthy control group ,and the difference was statistically significant (P＜0.01).After 12 weeks of IFX treatment ,the expression level of miRNA-802 in the intestinal mucosa and peripheral blood mononuclear cells of CD patients was significantly lower than that before treatment ,and the difference was statistically sig-nificant (P＜0.01).The results of correlation analysis have shown that the expression level of serum TNF-α was positively correlated with miRNA-802 expression in peripheral blood monocytes ,and the expression of miRNA-802 mRNA was significantly increased after the stimulation of TNF-α on peripheral blood monocytes cultured in vitro.Conclusion The increased expression level of miRNA-802 in IBD patients is closely correla- ted with the expression level of TNF-α ,and miRNA-802 could be a new treatment target for IBD.

Analysis of high risk factors for acute complex appendicitis in adults / 中华胃肠外科杂志

OBJECTIVE@#To explore the high risk factors of adult complex appendicitis, and to provide a reference for the development of a reasonable treatment strategy for acute appendicitis.@*METHODS@#A retrospective case-control study was conducted to collect clinical data of 312 adult patients with acute appendicitis confirmed by pathology undergoing appendectomy, including open and laparoscopic surgery, from May 2011 to August 2016 at Affiliated Hospital of Qingdao University. Age <14 years old, pregnant women, complicating abscess around the appendix, AIDS, blood system diseases, autoimmune diseases, inflammatory bowel disease or progressive cancer patients were excluded. According to the intra-operative findings and pathological types, patients were divided into complex appendicitis(112 cases, including gangrene and perforation) and non-complex appendicitis (200 cases, including simple and non-perforated appendicitis, ie suppurative appendicitis). After comparing the clinical data of these two groups, statistically significant variables were induded for multivariate logistic regression analysis to identify risk factors of complex appendicitis, and to establish a regression model. Enter method was applied to establish the regression equation: P=ExpiΣBiXi/1+ExpΣBiXi, and to calculate the relative risk of each variable. Meanwhile, retrospective and prospective verification was performed on this predictive model (cases of acute appendicitis from September 2016 to December 2017 were further collected). The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of complex appendicitis were calculated with the regression model.@*RESULTS@#Comparison of the clinical data between the complex appendicitis group and the non-complex appendicitis group showed that differences of 10 preoperative indexes were statistically significant, including period from abdominal pain to admission [(59.1±42.6) hours vs. (47.5±34.4) hours, t=3.051, P=0.002], white blood cell count [(12.9±3.7)×10/L vs. (9.2±4.0)×10/L, t=9.755, P<0.001], neutrophil count [(9.8±4.0)× 10/L vs.(7.1±3.9)×10/L, t=6.020, P<0.001], neutrophil percentage[(84.5±8.7)% vs.(68.2±16.0)%, t=12.754, P<0.001], C-reactive protein levels [(86.0±45.4) μg/L vs. (55.9±35.8) μg/L, t=7.614, P<0.001], serum albumin levels [(334.0±4.8) g/L vs. ( 41.0±4.3) g/L, t=16.055, P<0.001], vomiting ratio [44.6%(50/112) vs. 23.5%(47/200), χ²=14.980, P<0.001], high fever(≥39°C) ratio [16.1%(18/112) vs. 7.5%(15/200), χ²=5.577, P=0.022], the proportion of patients ≥60 years old [22.3%(25/112) vs. 13.0%(26/200), χ²=4.562, P=0.038] and previous history of appendicitis [16.1%(18/112) vs. 7.5%(15/200), χ²=5.577, P=0.022]. The above 10 variables were included in the logistic regression model for multivariate analysis. The results showed that six variables were associated with complex appendicitis. According to their strength, they were old age (≥60 years old) X1(OR=5.094), high fever (≥39°C) X2(OR=4.464), neutrophil count X6 (OR=1.269), neutrophil percentage X4 (OR=1.077), C-reactive protein level X5 (OR=1.027), and serum albumin level X3 (OR=0.763). A predictive regression model was established: P=1/[1+e], whose sensitivity and specificity of judging complex appendicitis were 76.8%(86/112) and 90.0%(180/200),respectively. Sensitivity and specificity for predictive value of complex appendicitis in further prospective validation of the model were 76.2%(48/63) and 81.1% (30/37), respectively.@*CONCLUSIONS@#Age ≥ 60 years old, body temperature ≥39°C, increased neutrophil count, neutrophil percentage and C-reactive protein levels, and hypoalbuminemia are risk factors for complex appendicitis. The establishment of predictive model may help determine complex appendicitis.
