OBJECTIVETo evaluate the long-term protection efficacy of neonatal hepatitis B vaccination on chronic hepatitis B (CHB) and liver fibrosis and cirrhosis in adults.

METHODSFrom January to October, 2013, a cross-sectional study was conducted among the participants from Qidong Hepatitis B Intervention Study (QHBIS), who were selected through stratified random sampling. The detections of serum alanine aminotransferase (ALT), HBsAg, anti-HBs, anti-HBc, HBeAg, and anti-HBe were conducted and ultrasonography on liver, gallbladder and spleen was performed for them. The positive rates of each serologic markers, the prevalence of active CHB and liver fibrosis and cirrhosis were calculated, the gender specific differences between vaccination group and control group were compared with Chi-square test.

RESULTSA total of 4 421 participants aged (25.59±1.84) years in vaccination group and 3 880 participants aged (26.61±2.24) years in control group were surveyed. The positive rates of HBsAg, anti-HBs, anti-HBc, HBeAg and anti-HBe were 2.38%, 37.73%, 3.78%, 0.57% and 2.15% in vaccination group, and 9.02%, 29.41%, 16.83%, 2.73% and 8.87% in control group, respectively, the differences between two groups were statistically significant (all P<0.05). The prevalence of active CHB and liver fibrosis and cirrhosis were 0.45% and 0.16% in vaccination group, 1.29% and 0.39% in control group, the differences between two groups were statistically significant (P<0.05). The active CHB prevalence was lower in females than in males in both vaccination group and control group (P<0.05). The liver fibrosis and cirrhosis prevalence was lower in females than in males in control group (P<0.05); whereas, no statistical significant difference in liver fibrosis & cirrhosis prevalence between males and females was found in vaccination group (P>0.05).

CONCLUSIONSProtection conferred by neonatal hepatitis B vaccination could last to marrying age. The gender specific difference in protection efficacy needs further study.

OBJECTIVETo investigate the expressions of gamma aminobutyric acid transporter 1 (GAT-1) and glutamate decarboxylase 65 (GAD65) mRNA in different brain regions at brain propofol uptake equilibrium in dogs.

METHODSEighteen 12- to 18-month-old healthy hybrid dogs were randomized equally into control group (group C), low dose group (group L), and high dose group (group H). In groups L and H, anesthesia was administered by intravenous injection of 5.5 and 7.0 mg/kg propofol followed by propofol infusion at a constant rate of 55 and 70 mg·kg(-1)·h(-1) for 50 min, respectively. Blood samples were taken from the internal carotid artery and jugular vein to measure plasma propofol concentrations, and the brain tissues of the hypothalamus, sub thalamus, dorsal thalamus, hippocampus, pons, parietal lobe and frontal lobe were examined for GAT-1 and GAD65 mRNA expressions using quantitative real-time PCR.

RESULTSIn groups L and H, propofol infusion at a constant rate for 50 min resulted in comparable plasma propofol concentrations between the internal carotid artery and jugular vein (P>0.05), but the concentrations differed significantly between the two groups (P<0.01). GAT-1 mRNA levels in the hypothalamus and hippocampus were significantly higher in groups L and H than in group C (P<0.05 and P<0.01), but comparable between the former two groups. The variations of GAT-1 mRNA levels between the hypothalamus and hippocampus were similar in both group L [(61.26∓7.17)% and (79.34∓39.95)%, P>0.05] and group H [(74.64∓19.63)% and (97.12∓32.31)%, P>0.05]. GAT-1 mRNA levels in other brain regions showed no significant difference among the 3 groups. GAD65 mRNA levels were similar between group L and group H, but both significantly higher than that in group C (P<0.01). GAD65 mRNA in other brain regions had no significant difference among the 3 groups.

CONCLUSIONGAT-1 mRNA in the hypothalamus and hippocampus and GAD65 mRNA in the dorsal thalamus are upregulated when propofol uptake reaches an equilibrium in the brain of dogs.

Objective To establish the model of VX2 soft tissue xenograft in rabbit, and choose the best time for PET-CT imaging. To analyze the result of the imaging with semi-quantitative, and evaluate the feasibility of the study with VX2 soft-tissue tumor model in rabbit for PET-CT imaging. Methods 20 Japanese white rabbits were successfully implanted with VX2 tumors in thighs by the injection of tissue mass suspension.Then they were scanned with PET-CT after the diameter of the tumor is ＞2 cm. Results The diameter of the tumor＞2 cm at 14 d post implant. The average volume of tumor was (114.57±9.87) cm3.The average SUVmax of tumor's and normal tissue's in the other thigh was 5.85±0.92 and 0.22±0.09 (t=27.03, P＜0.01). SUVmax was not associated with tumor volume (r=0.02, P=0.93).Conclusion The imaging of VX2 soft tissue xenograft is clear by clinic PET-CT, and it is suitable for the study of PET-CT.PET-CT imaging performed at 14 d post implantation had the highest imaging quality.

Objeetive To discuss the correlation of creatinine reduction ratio(CRR2)from posttransplant day 1 to day 2 and early graft function recovery status after kidney transplantation. Methods Clinical data of 80 patients after renal transplantation from Jan 2005 to Mar 2007 were retrospectively analyzed.Patients were divided into three groups according to the post-operative serum creatinine level:53 patients within IGF group[cereatinine＜265.2 μmol/L by post-operative day(POD)no.5],14 patients within SGF group(creatinine＞265.2 μmol/L on POD no.5,but no need for dialysis),and 13 patients within DGF group(need for dialysis in the first week post-transplant).Then the value and 99%CI of CRRz of these three groups were calculated. Results The value of CRR2 of IGF,SGF and DGF was(46.8±14.6)%,(25.6±13.5)%and(0.7±17.7)%respectively.And CRR2 99%CI of IGF,SGF and DGF was 41%-52%,15%-36%and-14%-16 0A respectively.There was significant difference in the value of CRR2 among IGF,SGF and DGF group.So a criteria for early diagnosis of IGF,SGF and DGF by CRR2 99%C1 was established:IGF(CRR2≥40%),SGF (15%＜CRR2＜40%)and DGF(CRR2≤15%). Conclusion CRR2 has a good correlation with early graft function recovery after kidney transplantation,and can be used to predict the occurrence of SGF and DGF.

Objective To observe the change of gastro-intestinal hormone levels about syndrome type of stagnation of liver qi, deficiency of spleen and stomach, liver qi stagnation and spleen qi deficiency in patients with irritable bowel syndrome (IBS), and to probe into the correlation between TCM syndrome type and gastro-intestinal hormone levels. Methods One hundred and three cases of patients with IBS were divided into liver qi stagnation group (35 cases), spleen and stomach deficiency group (30 cases) and liver qi stagnation and spleen qi deficiency group (38 cases), with normal group (10 cases) as control. Plasma motilin (MOT), somatostatin (SS) and cholecystokinin (CCK) were determined by radioimmunoassay. Result The plasma MOT level of spleen and stomach deficiency group was significantly higher than that in the normal controls (P

Objective To observe the effect and study intervenient action of Kuijieling Granules (KG) in treating ulcerative colitis (UC) during the active period by the clinical experiment. Methods The patients of active UC (damp-heat syndrome) were randomly divided into 2 groups (KG+SASP group and SASP group) to observe pathological changes of the mucosa,syndrome effect and main symptoms scores,and the protein expression of TLR4,CD14 and NF-?B p65 were detected by immunohistochemistry. Results KG+SASP group had better effect than SASP group in syndrome and mucosa (P0.05). There were outstanding differences among the pathologic grade of UC about IA of TLR4,CD14 and NF-?B p65. The expression of TLR4,CD14 and NF-?B p65 were decreased by treatment (P
