Objective To explore the relationship between polymorphisms of XbaI and MspI loci of apolipoprotein B (ApoB) gene and -75 bp,+83 bp loci of apolipoprotein AI (ApoAI) gene and coronary heart disease (CHD) in Kazaks of Xinjiang Uyghur Autonomous Region,China.Methods These loci were analyzed by PCR-restriction fragment length polymorphism (PCR-PFLP).Two hundred and five patients with CHD and two hundred and thirty six controls were involved.Results There were significant distinctions among low-density lipoprotein cholesterol (LDL-C),triglyceride (TG) and the ApoAI/ApoB ratio between the two groups,but no significant distinction among the polymorphism frequencies of the four sites between the two groups.The polymorphism coalition frequency of X-/Ms++/M1+-/M2++ (named Coalition 11) was significantly higher in CHD compared to the control group (14.6％ vs.7.2％,P ＜ 0.05).The level of total cholesterol (TC) in Coalition 1 1 was significantly higher and the level of the ApoAI/ApoB ratio in Coalition 11 was significantly lower than Coalition 1～10 in CHD patients.The level of the ApoAI/ApoB ratio of Coalition 11 was significantly lower than the Coalition 1～10 in control group.The levels of ApoAI/ApoB ratio of Coalition 3 were significantly higher compared to Coalition 11 in the two groups,respectively.The level of LDL-C of Coalition 3 was significantly lower than in the Coalition 11 in control group.The level of TC of Coalition 5 was significantly higher than Coalition 3 in the CHD group.The level of the ApoAI/ApoB ratio of Coalition 5 was significantly lower than in Coalition 3 or Coalition 1～10 of the two groups,respectively.The level of LDL-C of Coalition 5 was significantly higher than in Coalition 3 in control group.The ratio of ApoAI/ApoB was negatively related to TC,LDL-C and was positively related to HDL-C,both in CHD and control groups.Conclusion Coalition 11 of the 4 loci polymorphisms of the ApoB and ApoAI genes was correlated with CHD in Kazaks,and perhaps the ratio of ApoAI/ApoB was the most diagnostic parameter related with CHD among all lipid parameters.CHD may also be associated with Coalition 5,and,perhaps,Coalition 3 may have been confirmed as a protection factor against CHD,if more samples were enrolled.

ObjectiveTo investigate the safety of endoscopic retrograde cholangiopancreatography (ERCP) after Billroth-Ⅱ gastrectomy. MethodsA total of 43 patients who were admitted to our hospital and underwent Billroth-Ⅱ gastrectomy from June 2012 to June 2015 were enrolled and underwent ERCP. ResultsOf all 43 patients undergoing ERCP, 39 (90.7%) received successful intubation, 2 (4.7%) received failed intubation, and 2 (47%) experienced the complication of digestive tract perforation. Among the 39 patients who underwent ERCP, 31 (79.5%) were diagnosed with common bile duct stones (3 underwent sphincterotomy and 28 underwent endoscopic papillary balloon dilation to remove stones), 6 (15.4%) were diagnosed with benign stenosis at the end of bile duct (4 underwent papillary balloon dilation alone and 2 underwent biliary plastic stent implantation), and 1 patient each (2.6%) was diagnosed with ampullary tumor and hepatic portal metastasis of gastric cancer and received implantation of metal and plastic stents, respectively. One patient (26%) experienced acute pancreatitis after surgery. ConclusionERCP is safe and effective in patients after Billroth-Ⅱ gastrectomy and holds promise for clinical application.
