Levels of serum leptin were measured in 150 healthy, 50 PIH pregnant women before the delivery time and their newborns by Immuno radioassay(RIA) method. Serum leptin concentrations were correlated with body weight, body mass index, blood pressure, height of uterus bottom, waist circumference. Results were as follows: ① The serum leptin levels of PIH pregnant women (25 53?1 49?g/L) were significantly higher than those of the normal preghant women (21 13?4 08?g/L). ②The cord serum leptin levels of PIH pregnant women (12 23?4 39?g/L) were significantly higher than those of the normal preghant women (10 29?3 08?g/L). ③The leptin concentrations were positively correlated with body weight, body mass index, height of uterus bottom, waist circumference in the normal pregnant women, but not in the the PIH pregnant women. ④The correlations between leptin concentrations and systolic blood pressure, diastolic blood pressure, medium artery blood pressure in the PIH pregnant women were more obviously significant than those in the normal pregnant women. ⑤The correlations between the maternal serum leptin concentrations and newborns'body weight, body mass index were not significant both in the normal pregnant women and in the PIH pregnant women, however, the maternal serum leptin levels were positively correlated with the cord serum leptin levels in the PIH pregnant women, but not in the normal pregnant women. ⑥The correlations between the leptin levels of umbilical blood and newborns'body weight, body mass index were significant. It is suggested that ①Serum leptin levels of the PIH pregnant women and the neonatal are much higher than those of the normal pregnant women. ②The leptin concentrations of the maternal and the newborn are more correlated with themselves′ fat mass accumulation in the normal pregnant women. ③The cord serum leptin level is regarded as a reliable parameter for evaluating the fetal intrauterine growth. ④The maternal serum leptin level may serve as a marker for monitoring PIH.

Objective To investigate the applieation of restriction display (RD) technique in the preparation of HCV probes of clinical genotyping microarray. Methods Restriction enzyme Sau3A Ⅰwas chosen to digest the full-length HCV cDNAs of three distinct subtypes, i.e.1a, 1b and 2a. The resultant restrictive fragments were then ligated with universal adapters. PCR primers were designed to match the universal adapters but with one "nesting" base overhanging at the 3′- end. The PCR reactions were performed by ten pairs of different primer combinations. The differential genes were separated through polyacrylamide gel electrophoresis and silver staining. The second-round PCR was performed using the isolated bands as PCR templates. The purified PCR products were then cloned into T-vectors. The recombinant plasmids were extracted from positive recombinant clones and the target gene fragments were sequenced. Results The target HCV gene fragments ranging from 200 to 900bp were isolated and sequenced, which were correlated precisely with the RFLP (Restriction Fragment Length Polymorphism) prediction. A total of 66 different fragments were obtained, averaging about 22 for each subtypes. These fragments could be further used as probes in HCV microarray preparations. Conclusion RD technique is of great value in obtaining a large number of equal sized gene probes, which provide a swift protocol in generating DNA probes for the preparation of microarrays.

After treatment, the serum NSE, S-100β and NGF levels of the two groups were significantly decreased[(12.64±1.22)ng/L vs.(18.95±2.15)ng/L, (0.85±0.24)ng/L vs.(1.69±0.35)ng/L, (0.17±0.05)ng/mL vs.(0.98±0.12)ng/mL, (16.38±1.38)ng/L vs.(19.04±2.78)ng/L, (1.22±0.30)ng/L vs.(1.70±0.41)ng/L, (0.33±0.10)ng/mL vs.(0.96±0.14)ng/mL] (t=18.583, 14.010, 45.361, 6.239, 6.878, 25.58, all P<0.05), and the serum neurological function indicators of the observation group were significantly lower than those of the control group (t=14.592, 6.931, 10.358, all P<0.05). After treatment, the level of IgG in the two groups were significantly higher than those before treatment[(15.62±2.31)g/L vs.(9.12±1.74)g/L; (11.52±2.05)g/L vs.(8.97±1.56)g/L](t=16.363, 6.999, all P<0.05), and the IgG level in the observation group was significantly higher than that in the control group(P<0.05). There were no significant changes in the levels of IgM in the two groups before and after treatment (all P>0.05). Conclusion High-dose gamma globulin combined with naloxone can effectively improve the clinical efficacy of severe viral encephalitis in children, help to improve the clinical symptoms and signs of children, at the same time help to restore the nervous function of children and improve the humoral immune function, which is worthy of clinical application.

To obtain non-pathogenic rabies virus glycoprotein(RV-G),we expressed RV-G in Saccaromyces Cerevisiae(S.cerevisiae).In our study,tat-G fusion gene was cloned into the expression vector pYes2.0,which allows expression of a foreign gene in the yeast cells under the control of GAl1 promoter.Transforma-tion was performed by using lithium-treated yeast cells and several Ura+-tranformants were isolated.Ac-cording to the relative mobility in SDS-PAGE,we know probably two forms(designated as yGI and yGⅡ) of RV-G analogues produced in S.cerevisiae,their molecular weights were estimated as 66 kD and 56 kD,respectively.On the other hand,there was a specific band about 56 kD shown in western blot result.Com-bining precursors’ achievements,we will draw a conclusion that trans-membrane domain(TD) and cyto-plasmic domain have a negative regulation on RV-G antigen immunogenicity in S.cerevisiae.

Objective To examine the expression of IgA1 and B1a positive cells in palatine tonsils of IgA nephropathy (IgAN) patients, and to analyze the association between B1a cells and clinicopathological changes. Methods Eight patients diagnosed as IgAN by renal biopsy and 8 chronic tonsillitis patients without nephritis as control were enrolled in the study.Immunofluorescence and laser scanning confocal microscope (LSCM) were applied to observe the localization and quantitative calculation of Bla and IgA1 positive cells. Statistic analysis of the association of B1a cells with proteinuria and pathological Lee's grading was performed. Results Bla cells were mainly localized in germinal center of tonsil, and IgA1 positive cells were mainly localized in subepithelium of tonsil. Compared to control group, the percent of B1a cells and IgA1 positive cells was significantly higher in IgAN (P＜0.01). There was a positive correlation between Bla cells and IgA1 cells (P＜0.05). In IgAN, the percent of B1a cells in patients with hematuria and proteinuria was obviously higher than that of patients with hematuria only (P＜0.05). The number of Bla cells in IgAN patients with≥Lee's grade Ⅲ was significantly higher than that of those ＜ grade Ⅲ (P＜0.05). Conclusions IgA1 may be secreted by Bla cells in the tonsil of IgAN patients. The number of B1a cells is correlated with exacerbation of proteinuria and pathological severity, which may play an important role in pathogenesis of IgAN.

Objective To examine the correlation of urinary podocyte number and giomerular podocalyxin expression with clinicopathology in IgA nephropathy(IgAN)patients. Methods Morning urinary specimens(100 ml)3 days before renal biopsy from 50 patients with IgAN diagnosed by renal biopsy and from 20 healthy volunteers as control were collected. After centrifugation, 300 μI sediment was used for smear. Immunohistochemical staining with monoclonal anti-podocalyxin antibody was performed to detect urinary podocytes and the number of podocyte was counted under optical microscope. Computer image analysis system was used to examine glomerular PCX expression. Renal pathology and classification were investigated based on Lee's grading and Katafuchi semi-quantitative integration method. Relevance analysis was carried out on urinary podocyte number, glomerular PCX expression with pathological score and clinical data. Results The amount of urinary podocytes in IgAN was obviously higher than that in healthy controls(P<0.01). Significant differences were found in multiple comparison of the median of urinary podocytes among Lee's grade groups. I - II group was lower as compared to Ⅲ , Ⅳ, Ⅴ groups(all P<0.05). Ⅲ group was lower as compared to V group(P<0.05). The positive rate of urinary podocyte was the highest in Ⅳ and V groups(100%), while the lowest in Ⅰ - Ⅱ group(55%). Glomerular PCX expression in IgAN decreased with the aggravation of renal pathology. Significant differences were found in multiple comparison of the glomerular PCX expression with the pathological score. Lee's Ⅰ - Ⅱ group was higher as compared to Ⅲ, Ⅳ, Ⅴ groups(all P<0.05). Ⅳ and Ⅳ groups were higher as compared to V group(P<0.05). In IgAN, urinary podocyte excretion was negatively correlated with glomerular PCX expression(r=-0.702, P<0.01), positively correlated with 24-hour urinary protein(r=0.465, P<0.01)and positively correlated with glomerular and tubular scores(r=0.233, 0.307, P<0.05). Glomerular PCX expression was negatively correlated with 24-hour urinary protein(r=-0.367,P<0.05)and negatively correlated with glomerular and tubular scores(r =-0.560, -0.377, P <0.05). Conclusions Injury and desquamation of glomerular podocytes may involve in the development of IgAN. The number of urinary podocyte can reflect the loss of podocytes in renal tissue, which may be used as a marker of disease progression of IgAN.
