Background:14 C-urea breath test(14 C-UBT)is widely used for diagnosis of Helicobacter pylori(Hp)infection owing to its noninvasiveness and high sensitivity and specificity. Nevertheless,the presence of false-negative result can influence the diagnostic accuracy. Aims:To investigate the possible causes of false-negative 14 C-UBT for improving the accuracy of diagnosis. Methods:Eight-two cases with confirmed false-negative 14 C-UBT and 813 controls with true-positive 14 C-UBT at the People’s Hospital of Xinjiang Uygur Autonomous Region from Jan. 2014 to Aug. 2014 were enrolled. Patients in both groups were diagnosed as positive for Hp infection by Warthin-Starry silver staining combined with Hp stool antigen test. Univariate and multivariate analysis were performed to screen the factors related with false-negative 14 C-UBT. Results:In univariate analysis,5 variables were significantly different between case group and control group(P ﹤ 0. 05),and were taken into the multivariate analysis. Logistic stepwise regression analysis revealed that bile reflux( OR = 3. 961,P ﹤0. 001),post subtotal gastrectomy(OR = 9. 734,P ﹤ 0. 001),type Ⅱ Hp infection(OR = 1. 892,P = 0. 012)and upper gastrointestinal bleeding( OR = 4. 979,P ﹤ 0. 001 ) were the independent risk factors for false-negative 14 C-UBT. Conclusions:Bile reflux,upper gastrointestinal bleeding,post subtotal gastrectomy and type Ⅱ Hp infection might be the influential factors for false-negative 14 C-UBT. Combined tests for Hp infection should be suggested in patients with negative 14 C-UBT who had undergone subtotal gastrectomy or complicated with bile reflux or upper gastrointestinal bleeding.

Background: Helicobacter pylori (Hp) infection is associated with a variety of gastrointestinal diseases.Studies have shown that Hp eradication rate may be affected by the disease type and stage of disease progression.Aims: To investigate the influence of endoscopic ulcer stage on Hp eradication rate.Methods: A total of 423 peptic ulcer (PU) patients with Hp infection from January 2015 to July 2016 at the People's Hospital of Xinjiang Uygur Autonomous Region were enrolled.Of them,133 were gastric ulcer (GU) and 255 were duodenal ulcer (DU).A 14-day bismuth quadruple therapy was given for Hp eradication,and the eradication rates were analyzed with the endoscopic ulcer stage.Univariate analysis was conducted to identify factors influencing the eradication rate.Results: There was no significant difference in Hp eradication rates between GU and DU groups (82.7％ vs.83.9％,P>0.05).The eradication rates according to endoscopic ulcer stage were significantly different in GU group (active stage vs.inactive stage: 89.0％ vs.75.0％,P＜0.05);but in DU group,the eradication rate in active stage was similar to that in inactive stage (85.6％ vs.83.0％,P>0.05).Univariate analysis revealed that ulcer stage was correlated with the success rate of eradication;the eradication rate in active stage was significantly higher than that in inactive stage (87.8％ vs.80.3％,P＜0.05).Conclusions: Endoscopic ulcer stage is correlated with the Hp eradication rate in PU,especially GU patients.Hp eradication therapy performed in patients with active PU could yield a higher eradication rate.

The prevalence rate of diabetes is continuously increasing in China, and diabetes characterizes as high morbidity, low diagnostic rate, low cure rate, and low good control rate, which consequently resultes in the occurrence and progression of various diabetic complications and dramatically decreases the quality of life as well as the survival of diabetic patients.So it is crucial for clinician to screen diabetes early, make the diagnosis early, and start the treatment promptly.This article systemically summarizes the clinical manifestations, diagnostic criteria, typing, pathophysiology, complications, and management of diabetes.

Background:It has been demonstrated that serum perinuclear antineutrophil cytoplasmic antibody( pANCA)occurred significantly more often in ulcerative colitis( UC ) than in Crohn ’s disease( CD ),so it is of great importance for differential diagnosis of UC and CD. Aims:To study the correlation of serum pANCA with efficacy of aminosalicylic acids ( ASA)on UC. Methods:A retrospective study was conducted in 70 mild to moderate active UC patients admitted between Jan. 2007 and Dec. 2013 at People’s Hospital of Xinjiang Uygur Autonomous Region,all of them received oral mesalazine therapy,35 were positive and 35 were negative for serum pANCA. The efficacy was compared between the two groups. Results:After a four-week oral mesalazine therapy,the remission rate and overall efficacy were significantly higher in pANCA-positive group than in pANCA-negative group( remission rate:80. 0% us. 54. 3%,P﹤0. 05;overall efficacy:94. 3% us. 77. 1%,P﹤0. 05). Conclusions:Mesalazine is more effective in serum pANCA-positive UC patients. Being a specific immunological biomarker of UC,pANCA might be an indicator for predicting the therapeutic efficacy of ASA in UC patients.
