Ohjective To approach the therapeutic methods of urinary fistula after hypospadias urethroplas- ty.Methods Forteen post-hypospadia repair urethral fistula managed between 2000 to 2005 were reviewed.Differ- ent procedures were carried out according to the size and location of orificium fistulae.Results Eleven repairs were successful after one attempt.The success rate was 78% (11/14).Conclusion The procedure of fistula repair should be chosen according to the size,location and regional condition of orificium fistulae.

OBJECTIVETo evaluate the efficacy of hepatitis B vaccination on hepatitis B prevention and on hepatocellular carcinoma.

METHODSBirth cohort study, cross-sectional seroepidemiological survey, and surveillance of hepatitis B (HBV) and hepatocellular carcinoma were used to evaluate the efficacy of hepatitis B vaccination.

RESULTSDuring the 14 years after hepatitis B vaccination, the HBsAg positive rates were found to be 0.7% - 2.9%, with an average of 1.5%, and the protective rates were 83.5% - 96.6%. Hepatitis B virus infection rates of children immunized with hepatitis B vaccine were 1.1% - 5.1%, with an average of 2.2% and the protective rates of 93.5% - 98.4%. 15 years after hepatitis B vaccination, the incidence of hepatitis B dropped from 3.27/10 000 to 0.17/10 000, a 94.8% decrease, in the group of 0 - 19 year-olds.

CONCLUSIONThe universal infant hepatitis B vaccination has proved to be effective in reducing the incidence rate of acute hepatitis B as well as the mortality of hepatocellular carcinoma.

OBJECTIVETo investigate the dynamic changes of the anti-HBs level among immunized newborn infants born to HBsAg-positive and HBsAg-negative mothers in hyper-endemic area of Hepatitis B.

METHODSInfants who were regularly vaccinated with Hepatitis B vaccine and tested to be anti-HBs positive were divided into two groups according to HBsAg-positive or negative mothers in Long-an, Guangxi. Each subject was followed up 3 times during age 5 to 8. SPRIA was used to test HBsAg, anti-HBs and anti-HBc. Results During the follow-up period, positive rates of anti-HBs in children born to HBsAg-positive mothers ranged between 52.00% and 78.00%, and those with HBsAg-negative mothers was between 43.84% and 54.74%. GMT in two groups was between 55.36 mIU/ml and 95.66 mIU/ml as well as between 39.90 mIU/ml and 65.47 mIU/ml, respectively. There was no statistical significance in both positive rates and GMT between age groups. The anti-HBs level in the follow-up period of children born to HBsAg-positive mothers was higher than that of those born to HBsAg-negative mothers in the same age group. In the age group of 6-8 years with HBsAg-negative mothers, the positive rates in the follow-up period of children with high anti-HBs titers in the primary vaccination were 2.29-2.84 times of those with low titers. The anti-HBs titer of children in a follow-up period was lower than that in the primary vaccination, no matter whether they were born to HBsAg-positive mothers. However, the decline rate of children born to HBsAg-negative mothers was significantly higher than those born to HBsAg-positive mothers (84.91% vs. 61.54%; chi2 = 28.7982, P = 0.000). The incidence rate (25.64%) of a 4-fold increase in antibody titers of children born to HBsAg-positive mothers was significantly higher than that of children born to HBsAg-negative mothers (7.37%) from the primary vaccination to the follow-up period (chi2 = 6.7661, P = 0.009) with was 3.5 times of the latter. Subjects with HBsAg seroconvertion were those with low anti-HBs titers in primary vaccination.

CONCLUSIONThe anti-HBs level decreased slowly in successfully immunized children from age 5 to 8. The chance of natural booster yielded by natural infection increased in immunized children born to HBsAg-positive mothers. The anti-HBs level in the primary vaccination played an important role in prevention of seroconversion of HBsAg.

Objective To summarize clinical experience and explore application value of endoscopic clipping with histoacryl using in management of type 2 gastroesophageal varices. Methods Clinical data of 30 patients with type 2 gastroesophageal varices patients (including acute hemorrhage and primary prevention) from May 2015 to December 2016 were collected. Then evaluate therapeutic effect and safety of endoscopic clipping adjuvant therapy. Results Average glue dosage was (1.46 ± 0.70) ml, average using of clips were (5 ~ 6), and intraoperative needle pulling hemorrhage occurred in 2 cases. 14 patients (46.7%) underwent endoscopic re-examination, 3 patients (10.0%) achieved varicose vein elimination, 11 cases (36.7%) remained residual. Rebleeding occurred in 4 cases (13.3%), and 2 cases died (6.7%), one because of postoperative hematemesis and hemorrhagic shock, the other one died of spontaneous peritonitis and septic shock. For general curative effect, 2 cases (6.7%) were healed, 22 cases (73.3%) were improved, and 6 cases were unhealed (20.0%, 4 cases occurred rebleeding, 2 cases died); 17 cases underwent CT portal venograpy, abnormal embolization was not found in any patients, glue extrusion bleeding occurred in 1 case (3.3%), no patients had severe postoperative complications. Conclusion Endoscopic clipping with histoacryl can be used in the prevention and treatment of type 2 gastroesophageal varices to improve the treatment effect and reduce postoperative bleeding risk, may have good clinical practice value.
