Group-specific component(Gc), one of the polymorphic proteins of human plasma,has been isolated and purified from human plasma of Gc 2-2 phenotype by a procedure including DEAE-Sephadex-A50,Sephadex G100 and DEAE-Sephadex-A50 chromatography. The purified Gc identified by PAGE,SDS-PAGE and immunoelectrophoresis was homogeneous and reacted specifically with the commercial anti-Gc serum (DAKO) kit. The molecular weight of the purified Gc was about 58 kd.

Healthy skin sources from sex hormone, the reproductive health is closely related with skin, they grow and decline together. The methods of regulating menstruation and whites, nourishing kidney for pregnancy clinically can make patients’ skin regain brilliance in the meantime of curing sterility, menstruation disease and pelvic inflammation, from this we can know TCM has broad prospect in beautification.

Objective To investigate the weight loss mechanism of sleeve gastrectomy.Methods SD rats were fed with high-fat diet to induce obesity,and then the obesity rats were randomly divided into experimental group(underwent SG) and control group(underwent sham surgery).Eight weeks after operation,the body weight,food intake and peripheral blood concentration of Ghrelin,GLP-1,PYY3-36 of rats were checked.Results Compared with controll group,in experimental SG model,food intake was decreased(P 0.05).Conclusions The weight loss of sleeve gastrectomy in DIO rats's decline is lasting and obvious.The postoperative effect of decreased Ghrelin and increased GLP-1,PYY3-36 is the main mechanism for weight loss.

Anti-GC serum was successfully prepared in two New Zealand rabbits immunized with GC protein which was isolated and purified from GC2-2 serum previously in our laboratory. The results of identification showed that the specificity of the home made anti- GC serum and the commercial anti- GC serum (DAKOPATTS) were identical. The titer of the home made anti-GC serum was 128. Three common phenotypes, GC1-1, GC2-1 and GC2-2could be identified by immunoelectrophoresis with the home made anti-GC serum. The concentration of GC protein as low as 3.1 ?g/ml could be detected by double immunodiffusion. In addition the anti-GC serum does not cross react with other human serum proteins.

Objective:To establish a mouse model with the main characteristics of asthma and to study the pathogenesis of its airway inflammation.Methods:Mice were given latex by the intraperitoneal sensitization/intranasal challenge.BALF histology were examined 24 hours following tracheal challenge;cytokines and serum total and specific IgE were examined in one month and the expression of IL-5?IFN-? were performed by ELISA ?RT-PCR.Results:After the latex challenge,in experimental group,the number of total BALF cells and the percentage of eosinophils elevated;the histological analysis showed the elevation of mucus production and goblet cell development within bronchial epithelium,spasm and constraction of bronchia ,marked peribronchial infiltration of eosinophils and lymphocytes; the elevation of total and specific IgE;reduction of IFN-? and increase of IL-5 in the BALF and lung.Conclusion:Latex sensitization and challenge can lead to airway eosinophilia,allergen-specific IgE induction and production of Th2 type cytokines, which were the main characteristics of asthma.

A PAGE IEF immunoassay was established to detect the ORM, Pi, AHSG and GC phenotypes slmultaneously in human bloodstains. The cumulative discriminating power and probability of paternity exclusion were 0. 9878 and 0. 6648 respectively. Human sera diluted 100 times and bloodstains kept at room temperature for 4 weeks could be typed for these four blood groups correctly. The phenotypes of ORM, AHSG and GC could be determined correctly in bloodstains kept at room temperature within 24 weeks. This provides a good approach for individual identification of human bloodstains.

Objective To investigate the association between the EPHX2 polymorphism G860A and the risk of hypertension in mild ages. Methods In a hospital based case-control study, one common polymorphism C860A in EPHX2 gene in a case-control study of 100 hypertension and 300 age- and sex frequency - matched disease-free controls were genotyped in a Southern Chinese population. SAS 9. 13 was used toanalysis the polymorphism and hypertension risk. Results Genotype frequencies of EPHX2 G860Alocus between the cases and the controls were significantly different (P =0. 01). Compared with the most common 860GG genotype, the 860GA heterozygote had an increased risk of hypertension (adjusted OR =1.98; 95%CI = 1.19 -3.51), the AA homozygote had a further increased risk of hypertension (adjusted OR =2. 84; 95%CI = 1.01 -6. 11). There was a significant trend for an allele dose effect on risk of hypertension (P trend = 0. 03). Conclusions EPHX2 polymorphism G860A is associated with an increased risk of hypertension, and the 860A variant may be a marker for susceptibility to hypertension.

Objective To systematically evaluate the curative effect of sequential treatment and standard triple therapy in eradicating Helicobacter pylori and the risk of adverse events between the two therapies.Methods The related studies were searched with electronic databases to evaluate the efficacy of sequential therapy and standard triple therapy in eradicating H.pylori.Information was retrieved including the clinical features of patients,quality of research,eradication rate of H.pylori and incidence of adverse events and so on.The pooled relative risk(RR)and 95%confidence intervals(95%CI)were calculated,and the publication bias was assessed with funnel plot. Results Twelve randomized trials were performed,and 3183patients met the internalization criterion.Meta analysis demonstrated a clear superiority of the sequential therapy over 7-day triple therapy with an RRof 1.23(95%CI:1.19-1.27),over 10-day triple therapy with aRRof 1.17(95%CI:1.10-1.24),and over 14-day triple therapy with a RRof 1.25(95%CI:1.06-1.48).The incidence of adverse event was similar with sequential therapy versus that of triple therapy(RR=0.96,95% CI:0.75-1.23).Conclusions Sequential therapy is associated with a higher eradication rate of H.pylori compared with 7-day,10-day and 14-day triple therapy.The adverse event doesn't increase significantly.

Objective To investigate the effect on NO、IL-10、CRP and bacterial translocation rate by glutamine enriched parenteral nutrition solution in purulent appendicitis in children.Methods72 cases of acute suppurative appendicitis complicated with peritonitis were selected and randomLy divided into control and treatment groups.Patients (36 cases) in the control group were given antibiotics and parenteral nutrition support for 7 days, 36 cases in the experiment group were given glutamine enriched parenteral nutrition solution for 7 days.NO、IL-10、 CRP and bacterial translocation rate were compared after the treatment.ResultsCompared with before treatment, two groups of patients with content of FT3, FT4 was higher(P<0.05), CRP, NO and IL-10、 content in serum was lower (P<0.05), 16Sr and BG positive rate was lower (P<0.05).Compared with the control group, the serum FT3, FT4 was higher(P<0.05), CRP, IL-8 and IL-6 content in serum was lower (P<0.05), 16Sr and BG positive rate was lower (P<0.05).ConclusionGlutamine enriched parenteral nutrition solution can significantly improve thyroid hormone levels,reduce serum CRP, bacterial translocation rate, and adverse reactions were mild.
