Objective To compare the clinical results between living related and cadaveric donor renal transplantation in the same immunosuppressive regimen and HLA match. Methods Twelve cases of living related donor renal transplantation and 22 cases of cadaveric donor renal transplantation were analyzed retrospectively. The 1-, 3-year patient/graft survival rate, renal function and 1-year acute rejection rate were analyzed respectively.Results No renal function injury and surgical complications were found for living donors during the follow-up period. In living donor group and cadaveric donor group, 1-year acute rejection rate was 16.7 % and 22.7 % respectively (P 0.05). Renal function in living donor group was better than that in cadaveric donor group (P

Objective:To explore the mechanisms by which DNA methylation regulates miR-126 and its host gene EGFL7 in CD4+T cells from patients with systemic lupus erythematosus (SLE).
Methods:We analyzed the expression and the DNA methylation status within promoter region of EGFL7 and miR-126 by real-time qPCR and bisulifte genomic sequencing analysis.
Results:miR-126 and EGFL7 mRNA expression was upregulated in CD4+T cells from SLE compared with that from healthy controls (P<0.01). EGFL7 mRNA level was positively correlated with miR-126 expression in CD4+T cells from SLE (r=0.538, P=0.015). The average methylation level of EGFL7 promoter in CD4+T cells from SLE was lower than that from healthy controls (P<0.05).
Conclusion:hTe upregulation of miR-126 and its host gene EGFL7 expression in CD4+T cells from SLE is associated with the hypomethylation of the EGFL7 promoter.

An improvement of chemiluminescent system for determination of peroxynitrite anion (ONOO-) has been made. In this system, the effect of some antioxidants for scavenging ONOO- was tested. The constitute of this system and the program of starting were followed as: The ozone (O3) was bubbled through a glass-frit into 10 ml 0.01 mol/L solution of sodium azide in CB(pH 10.5) to generate ONOO-. The 800 μl ozonized solution of azide was injected into a glass tude in situ which contains 100 μl sample and 100 μl luminol solutions to initiate chemiluminescence (CL). The pluses / 6 seconds (CP6S) were determined immediately and continually for 10~30 times. A certain CL intensity (CP6S) was chosen as evaluation index to compare the activity of antioxidants. This chemiluminescent system is sensible, simple and stable. The determination limit was 8.74 μmol/L ONOO-. The linear rang was 8.74~74.04 μmol/L ONOO-. The intra batch and inter batch variation coefficient (CV%) of the analysis were 3.35%(n=10) and 5.52%(n=10) respectively. It was tested that Vit.C, teapolyphenol, procyanidin and thiourea all have effects on scavenging ONOO-.

Objective:Some antigens of M.tb to culture with peripheral blood mononuclear cells ( PBMC) for assaying their proliferation and activation,so as to signify whether lipid antigens of M.tb have specific immune responses in host against M.tb infection or not.Methods:We treated PBMC with several lipid antigens of M.tb to explore the ability of these antigens to activate immunity in healthy individuals.We measured and analyzed cell proliferation by labeling cells with carboxyfluorescein succinimidyl amino ester (CFSE) and subjecting them to flow cytometry (FCM).The production of IFN-γ,TNF-αand IL-4 by T cell subsets (NKT,CD4+, CD8+,andγδT) from healthy donors was analyzed by FCM after stimulation with autologous immature dendritic cells pre-cultured with M.tb lipid antigens.The tested M.tb lipid antigens were the total lipid (TLIP),Acetone-Soluble Lipids (ASLIP),Purified Sulfolipid (PSLIP),Lipoarabinomannan (LAM) and Lipomannan (LM) levels.Medium free of lipid antigens(WCL,CFP,LPS,Mtb-HAg and blank) was used as a control.Results:We found the proportion of proliferative NKT and CD8+T cells significantly increased in all lipid groups (P<0.05).ASLIP,LAM and LM promoted non-proliferative CD4+T cells to secrete IL-4 and proliferative ones to secrete IFN-γ( P<0.05).All lipid antigens promoted both proliferativeγδT cells and CD8+T cells to secrete IFN-γand TNF-α,but the proportion of TNF-α-secreting cells in these populations decreased in the LM group ( P<0.05 ).Conclusion: Lipid antigens may affect the CD1-restricted T cells of the host to fight M.tb infection.

OBJECTIVE:To systematically review the efficacy and safety of glipiaide versus repaglinide in treatment of type 2 diabetes and provide evidence-based reference for the clinical treatment. METHODS:PubMed,EMBase,Medline,Cochrane Li-brary,CJFD,VIP and WanFang database were retrieved to collect the randomized controlled trials(RCT)of the efficacy and safety of glipizide(test group)versus repaglinide(control group)in the treatment of type 2 diabetes. After the quality evaluation and in-formation collection of clinical studies with inclusion criteria,Rev Man 5.2 software was conducted for Meta-analysis. RESULTS:There were totally 10 RCTs,involving 1 022 patients. Meta-analysis results showed that the HbA1c levels [MD=0.43,95%CI (0.20,0.65),P<0.001],2 h postprandial plasma glucose levels [MD=0.49,95% CI(0.04,0.94),P=0.03] and hypoglycemia inci-dence [OR=2.99,95%CI(1.83,4.88),P<0.001] in test group were significantly higher than control group. There was no signifi-cant difference in the fasting plasma glucose level in 2 groups[MD=-0.14,95%CI(-0.44,0.16),P=0.35]. CONCLUSIONS:Re-paglinide has better efficacy and safety than glipizide in the treatment of type 2 diabetes. Limited by the methodological quality and sample amount of included studies,it remains to be verified by RCT with large sample,strict design and long-term follow-up.

Objective To investigate the effect of rivanol induction on pregnancy termination for patients with placenta previa during midtrimester.Methods From January 2010 to December 2015,16 patients of placenta previa underwent pregnancy termination induced by rivanol during midtrimester were regarded as the observation group, and 22 patients with normal placental position were regarded as the control group.The delivery time,amount of postpartum hemorrhage within 24 hours,one-time success rate of induced abortion,caesarean due to massive haemorrhage and postoperative infection of the two groups were recorded to analyze the clinical effect of rivanol.Results There was no statistically significant differences in the success rate,delivery time and caesarean due to massive haemorrhage between the two groups(P>0.05).The amount of intrapartum and postpartum hemorrhage in the observation group was more than that of the control group,with a statistically significant difference(P<0.05),but it was less than 500 mL,which did not significantly increase the related risk for patients.Conclusion Induced abortion by rivanol is a simple,safe and effective method for patients with placenta previa during midtrimester with fewer side effects and less trauma,which is the preferred method for such patients.

Objective To clone and express prokaryotic recombinant plasmid of nucleoside triphosphate hydrolase (NTPase) gene of Toxoplasma gondii, and analyze its antigenicity. Method NTPase gene was amplified by PCR from RH strain of T. gondii and cloned into pGEM-T Easy vector. Positive clones were screened and identified by BglⅡ, HindⅢ digestion and sequenced. The target gene was then subcloned into prokaryotic expression vector pBAD-HisB and transformed into E. coli BL21(DE3). The expressed recombinant protein was purified with Ni-NTA agarose and further analyzed by sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE) and Western blotting. Results NTPase-Ⅱ gene was specifically amplified, and the homology of DNA sequence was 100% to that in the GenBank. SDS-PAGE showed that the recombinant NTPase protein with correct molecular weight was expressed highly in E.coli BL21(DE3). Western blotting testified that the purified recombinant protein could be specifically recognized by mouse serum immunized with T. gondii and mouse anti-recombinant protein serum. Conclusion The NTPase-Ⅱ gene has been cloned and expressed in E.coli BL21(DE3), and the purified protein of NTPase-Ⅱ gene displays a specific antigenicity.
