ABSTRACT
Objective To analyze the failure ratio and the causes of the inoculation failure of hepatitis B virus(HBV)-vaccine in children and relevant the remedial measures. Methods One thousand three hundred and sixty cases treated in Suzhou Wuzhong people′s hospital during Jan.2007 to Jul.2008 were chosen,of whom 286 children from 1-5 years old to be anti-HBs negative or anti-HBs titre to be 0-10 IU/L were screened,and specific failure reasons for the vaccination were analyzed,also the timely treatment measures were taken.Then 286 children were divided into 5 groups randomly.Apart from one group was set up as blank control,the other 4 groups were arranged to accept different immunization methods with 0,1,2 month schedule,group A simply got revaccinated with HB vaccine(10 ?g) 3 times;group B revaccinated with double dosage of HB vaccine(20 ?g) 3 times;group C besides being revaccinated 3 times,the immune regulatory agent was jointly used;group D revaccinated 3 times with genetically engineered CHO hepatitis B vaccine. Results The ratio of failure of HBV-vaccine was 21.03%,what caused failure of hepatitis B vaccine included immunologic inadequacy 218(76.22%),repeated respiratory infection 192 cases(67.13%),abuse hormone 140 cases(48.95%),zinc deficiency 129 cases(45.10%),anaemia 108 cases(37.76%),passive smoking 80 cases(27.97%),the mother being chronic parenchymatous nephritis or HBV carrier 63 cases(22.03%),premature 54 cases(18.88%),adiposity 38 cases(13.29%),dystrophy 29 cases(10.14%).There were 4 methods of revaccination,the positive rate for group A,B,C,D were 90.00%,96.47%,99.08%,95.83%,respectively.Group C had the highest positive rate,compared with the other 3 groups,which were statistically significant(P a
ABSTRACT
Objective To explore the correlation between Helicobacter pylori (Hp) infection and recurrent abdominal pain (RAP) in children over 6 years old and its relative treatment.Me-thods One hundred and eighty children over 6 years old with the diagnosis of RAP from Mar.2007 to Feb.2009 were selected,30 healthy children without RAP were taken as the healthy control group at the same period.14C-urea breath test (14C-UBT) was used to detect whether the patient was infected by Hp.The radical cure of Hp was given to the Hp-positive children with RAP,and the remission rate of children with RAP and the Hp negative rate were observed.Results The positive rate in RAP group was 58.33%,which was higher significantly than that in healthy control group(20.00%)(P0.05).The positive rate of those with and without bad eating habits were 45.56% and 12.78%,and the positive rate of with and without family gastrosis history was 49.44% and 8.89%,which both had significant difference between them(Pa
