Objective To investigate the efficacy and the mechanism of different dose hepatitis B immunoglohulin(HBIG)on prevention of HBV intrauterine infection and HBV S gene mutation. Methods HBV carrier mothers were randomly divided into three groups.Eighty-one HBsAg carrier pregnant women were divided into HBIG A group.HBIG B group and control group.Each subject in the HBIG A group received 200 U or 400 U(for HBsAg and HBeAg double positive carrier)intra muscularly at 3,2,1 month before delivery.Each subject in the HBIG B group received 200 U intra muscularly at 3,2,1 month before delivery.The subjects in the control group did not receive any treatment.Maternal blood samples were taken before HBIG injection and at delivery.Neonatal blood samples of all newborn infants after birth were taken before immunopropbylaxis.Their sera were ob tained to test HBV markers by enzyme immunoassay(EIA)and HBV DNA by fluorescence quantita- tive polymerase chain reaction(FQ-PCR),then to amplify and sequence HBV S gene region.Results The rate of HBV intrauterine infection in the HBIG group(14.5%)was lower than that in the control group(35.7%)(X~2=4.896,P=0.027).The rate of HBV intrauterine infection of newborns from HBsAg and HBeAg double positive carrier mother in the HBIG A group(37.5%)were lower than control group(100.0%)(X~2=7.273,P=0.007),while the rate was no different in the HBIG B group(71.5%)and the control group(X~2=2.637,P=0.104).Maternal HBsAg titer and HBV DNA level were of no difference among three groups before HBIG injection.Maternal HBsAg titers and HBV DNA levels of the HBIG A group were lower than those of the HBIG B group and the con- trol group at delivery.Among the 26 neonatal serum samples in the HBIG A group,10(38.5%)were positive for anti-HBs,while in the HBIG B group and in the control group,no neonatal serum sam- ples was positive.There was no significant difference of nucleotide and amino acid changes in the S gene between the HBIG group and the control group.Conclusions HBV infection in the uterus may be interrupted by injection HBIG intramuscularly before delivery.More efficacy would be found using variable HBIG dose according to different HBV virema and must be once more again injected just he- fore one week of delivery;anti-HBs transported to the fetus via the placenta and it's may be the im- portant mechanism of HBIG prevention.Asymptomatic HBsAg carrier mother received injections of HBIG before delivery should not influence HBV S gene mutation.Gene mutation of HBV is not the main factor in intrauterine transmission of HBV.

Objective To investigate the effects of dietary consumption of monounsaturated fatty acid (MUFA) on the control of type 2 diabetes mellitus. Methods One hundred and eighty-five patients with type 2 diabetes mellitus from a community in Shanghai were randomly divided into MUFA intervention group (MUFA group,n=125) and control group (n=60). The patients in MUFA group consumed tea oil enriched in MUFA for 3 months,while those in control group consumed normal oil. The serum glucose (fasting plasma glucose and 2-hour postprandial glucose),fasting insulin and blood lipid were examined before intervention and three months after intervention,and the parameters were compared within groups and between groups. Results The serum fasting glucose,fasting insulin,total cholesterol and low density lipoprotein-cholesterol 3 months after intervention were significantly lower than those before intervention in MUFA group (P0.05),while the serum fasting glucose,total cholesterol and low density lipoprotein-cholesterol in MUFA group were significantly lower than those in control group 3 months after intervention (P0.05). Conclusion Dietary consumption of MUFA can improve the glucose and lipid metabolism in patients with type 2 diabetes mellitus.
