Objective To compare the effect of the new and traditional anastomotic modes on the life quality of the patients with esophageal cancer. Methods 400 cases of the patients with esophageal cancer were randomly divided into A and B group. All the patients received the anastomosis of the no imbedding with 3 rows suture through the pathway of thoracotomy allied with left neck,anteriolateral surface of right thorax and the epigastrium middle line. In group A the patients received the anastomosis with esophageal arc amputation and gastric half-arc amputation. In group B the patients received the traditional anastomosis with esophageal horizontal amputation. After operation the amount of taking foods, the width of anastomotic stoma, the amount of barium reflux, pH value of esophagorrhea, 24 hours pH value of esophagorrfea and intraesophageal pressure were measured in both the two groups patients. Results 13 cases of anastomotic fistula happened in all the patients, amounted to 3.25%. 5 cases had infection in the chest with 3 cases dead (1 from Group A, 2 from group B).All obove indices showed remarkable difference between the two groups of the patients except intraesophageal pressure. Conclusion The new anastomotic mode can improve the life quality of the patients with esophageal cancer much more than the traditional anastomotic mode.

OBJECTIVETo understand the positive rates of hepatitis B surface antigen (HBsAg) and surface antibody (anti-HBs) among adults aged ≥18 years in communities in Chaoyang district, Beijing.

METHODSHBsAg and anti-HBs were tested with ELISA reagents for participants in the Community Diagnosis Survey (3 000 person were sampled in each community according to the age and sex distribution of the residents) in all 42 communities in Chaoyang district by Beijing Center for Disease Control and Prevention (CDC) and Chaoyang CDC. The data of 35 communities in which at least 1 000 adults were tested were analyzed.

RESULTSA total of 78 100 adults were tested for HBsAg and anti-HBs in the 35 communities. The crude positive rate of HBsAg was 2.24% (95% CI: 2.13%-2.34%). The highest age-specific HBsAg positive rate was 3.00% (95% CI: 2.56%-3.44%) for those aged 40-44 years and the lowest age-specific HBsAg positive rate was 1.69% (95% CI: 1.29%-2.09%) for those aged 18-24 years, respectively. A obvious difference in community- based HBsAg positive rate was founded with the highest of 10.68% (95% CI: 9.43%-11.94%) and lowest of 0.24% (95% CI: 0.13%-0.38%). HBsAg positive rate was significantly lower in local residents than in participants with household registered in other provinces (1.97% vs. 2.98%, P<0.01), but the sex specific difference in HBsAg positive rate was relatively smaller (2.45% in males and 2.07% in females, P<0.01). The multivariate logistic regression analysis showed that age, community, occupation, residence status and sex were all associated with positive rate of HBsAg (P<0.01). The overall positive rate of anti-HBs was 30.85% (95% CI: 30.53%-31.18%), and the highest was 38.10% in age group 18-24 years (95% CI: 36.58%-39.61%) and the lowest was 28.88% in age group 75- years (95% CI: 27.62%-30.15%), respectively. Up to 67.02% of the subjects were both HBsAg and anti-HBs negative (95% CI: 66.69%-67.35%), and the age specific difference was not significant. But significant differences in anti-HBs positive rate and the negative rate of both HBsAg and anti-HBs were found across communities.

CONCLUSIONThe overall positive rate of HBsAg was at a moderate low level among adults in Chaoyang, but the age specific positive rate was high in the middle-aged and the population specific positive rate was high in participants with household registered in other provinces, therefore, the prevention and control of hepatitis B in Chaoyang should be focused on the middle aged people and participants with household registered in other provinces. The community specific differences in the positive rate of HBsAg and anti-HBs across communities need to be further studied.
