OBJECTIVE: To study ApoB gene genetic polymorphism of Han nationality and Mongolian nationality in midwest area of Inner Mongolia. METHODS: Some unrelated individuals of Han nationality and Mongolian nationality in midwest area of Inner Mongolia were selected. Polymerase chain reaction-restriction fragment length polymorphism technology was used to check the presence of Xba I (X+) and EcoR I (E-) sites of rare alleles. The genotype frequency, allelic frequency and population genetics parameters were calculated. RESULTS: The frequencies of Xba I (X+) and EcoR I (E-) rare alleles were 2% and 4.6% in Han population. There was no Xba I (X+) or EcoR I (E-) rare alleles found in Mongolian nationality. CONCLUSION The allelic frequencies of ApoB gene Xba I and EcoR I sites are very different in different races. These sites may be used in identification of ethnicity.

Objective To evaluate the feasibility, safety, and efficacy of Y-shaped jogged stent in patients with malignant hilar biliary obstruction. Methods During the period of January 2010 to June 2015,We retrospectively reviewed 98 cases of malignant hilar biliary obstruction who were received implantation of biliary tract stent. 17 consecutive patients who were treated with Y-shaped jogged stent were identified (group A) during January 2012 to June 2015. Group A was carefully matched according to patients' age, sex, type of tumor, stage, type of biliary obstruction, level of bilirubin at diagnosis, presence of metastasis and treatment, and 17 patients who were underwent unilateral stent placement alone with PTCD were chosen as control group (group B). Patients' baseline characteristics, stenting strategy, complications, stent patency time and survival rates were analyzed, and continuous variables of the two groups were compared using Student's t-test. Categorical variables were analyzed using the Fisher exact test. Results Y-shaped jogged stent implantation group and control groups were closely matched in terms of patients' age, sex, type of tumor, stage, type of biliary obstruction, level of bilirubin at diagnosis, presence of metastasis and treatment ( P>0.05). The bilirubin decreased rate in the two groups was 88.2%and 53.0%respectively (P<0.05). The median time of stent patency after stent implantation was(7.3 ± 1.0)months and(5.7 ± 0.9) months respectively (χ2=4.04,P=0.044), and the median survival time was(9.1 ± 1.5)months and(7.2 ± 1.1)months (χ2=4.60,P=0.032), with significant difference according to Kaplan-Meier analysis. There were no severe complications such as massive hemorrhage, perforation, biliary fistula and severe pancreatitis, which were associated with stent implantation. Conclusions The application of Y-shaped jogged stent is safe, feasible and effective in patients with malignant hilar biliary obstruction. It can relieve the clinical symptoms of biliary obstruction effectively with prolongation of stent patency time and survival rate significantly.

Objective To investigate the reasons and the methods of prevention and cure for serious complications of radiofrequency ablations in the treatments of hepatocellular carcinomas. Methods A total of 410 patients with BCLC at A or B stage of hepatocellular carcinomas in our hospital were enrolled between November 2014 and June 2009. These patients underwent a total of 504 times radiofrequency ablations for the treatments of liver lesions. This retrospective study analysed the reasons and the strategies of prevention and cure for the serious complications. Results In the patients with a total of 504 times radiofrequency ablations, 2 patients had massive hemorrhage caused by puncture injuries, 2 patients had the tumors which were close to the liver capsules and 1 patient had bile peritonitis caused by the injury of thermal ablation on the gallbladder. The maximum diameter of tumor was 5 cm. That tumor was close to the gallbladder. 2 patients had needle tract metastases caused by incompletely needle path ablations. 1 of the 2 patients had a tumor near the liver capsule, and the other patient had un-enough temperature for needle path ablation. Tumor outbreaks were happened in 2 patients. 1 of the 2 patients had a tumor which was located in the liver capsule and close to the portal vein. The other patient had a 12 cm diameter tumor with rich blood supplement. 2 patients had liver abscesses. 1 of the 2 patients had a tumor near the ascending colon, and the other patient had diabetes. 1 patient had colonic perforation caused by thermal ablation. The tumor in that patient was located in the right hepatic lobe segment and adjacent to the ascending colon. The incidence of serious complications was 1.98% (10/504). Conclusions The incidence of the serious complications of radiofrequency ablations for the treatments of hepatocellular carcinomas is relatively low. The main reasons for the serious complications were direct injuries caused by punctures, heat radiation injuries, tumors adjacent to large blood vessels, gallbladders and intestines, tumors with abundant blood supplement, needle paths fail to cross normal liver tissues, low scores of liver function, weak immune system and diabetes. The key points for avoiding and reducing the serious complications are preoperative evaluations of patients' basic situations, choices of appropriate puncture channels and control ranges of ablations when tumors are close to important blood vessels, intestines and gallbladders.
