Objective To study the relationship between perioperative detection of forkhead box protein P 3(Foxp3) mRNA level in peripheral blood mononuclear cell (PBMC ) of patients with kidney transplantation and chronic allograft nephropathy (CAN ) . Methods 35 cases of renal allografts completed in this hospital defined clinically and confirmed histopathologically were observed as CAN group ,simultaneously a retrospective case-control study was performed on 35 renal transplant recipients with normal graft function observed(control group) .Foxp3 levels of PBMC in perioperative period were dynamically determined in two groups .Real time PCR was applied to detect the expression of Foxp3 mRNA .In order to find out other risk factors influencing chronic allograft nephropathy and eliminate disturbance .The related clinic factors were compared between the CAN group and the control group .Re-sults The Foxp3 mRNA level was lower in the CAN group than the control group [(24 .1 ± 16 .2) × 10-4 vs .(52 .3 ± 27 .4) × 10-4 ,P<0 .01] .Among risk factors influencing chronic allograft nephropathy ,only acute rejection(AR) was probably different in two groups .In order to avoid disturbance ,further classification was done according to AR .The statistical results show that the Foxp3 mRNA level in two groups was not be affected by AR .Conclusion The Foxp3 mRNA level in perioperative period is associ-ated with CAN which maybe a risk factor for CAN .Foxp3 may be an index to predict the occurrence risk of chronic allograft ne-phropathy after kidney transplantation and guide individual treatment .

Objective To study the influences of endogenous testosterone on vascular endothelial cell function and structure in rabbits of balloon injury. Methods Twenty male rabbits were randomly divided into two groups: castrated group and control group.The former group animals were castrated and the later group animals received sham operation. All animals were performed with deendothelializing balloon injury in the right iliac artery. Nitric oxide (NO) and endothelin-1 (ET-1) were measured at different intervals during the experiment. After 2 weaks of endothelial denudation all animals were killed, and endothelin structure and morphological changes were observed with electron microscope and HE staining. Results There weren′t siginificant differences of plasma NO and ET-1 levels between the two groups, but plasma NO and ET-1 levels of the castrated group 2 weaks after endothelial denudation recovered to the levels before castration, while they didn′t in the control group. The extent of reendothelialization and intimal area of the harvested segments were similar between the two groups. Conclusion The decrease of endogenous testosterone level did not affect endothelial cell structure, but tended to protect function of injured endothelium.

AIM: To study the dynamic change of chemical components in the compatibility of Carthamus tinctorius L.with Glycyrrhiza uralensis Fisch during decoction together. METHODS: By means of HPLC analysis and phytochemical isolation technique,focusing on the differences between chemical components in co-decoction and individual decoction.Two chemical substances which showed quantitative changes during co-decoction had been isolated and identified as Licochalcone A and Licochalcone B,respectively. CONCLUSION: From the method described in this article,it could be concluded that the chemical profiles of TCM drug-pairs prepared by co-decoction are different from that of extract mixture combined by the individual extract of Carthamus tinctorius L.and Clycyrrhiza uralensis Fisch,respectively.

Objective To investigate the distribution of the MDR1 exon12 (C1236T), exon21 (G2677T/A) and exon 26 (C3435T) gene polymorphisms in breast cancer patients, and to analyse their relationship with molecular subtypes of breast cancer. Methods The genotyping of C1236T, G2677T/A and C3435T were detected by polymerase chain reaction (PCR)-high resolution melting (HRM) method in 400 cases of breast cancer. The Hardy-Weinberg equilibrium test was used for ge?netic equilibrium distribution of genotype. The molecular subtypes of breast cancer were classified based on St.Gallen Con?sensus 2013. The genotype distributions of C1236T, G2677T/A and C3435T in breast cancer were analyzed. Their relation?ship with molecular subtypes in breast cancer was analyzed as well. Results ①In 400 cases of breast cancer, there were 2, 3 and 2 specimens did not get genotyping results in C1236T, G2677T/A and C3435T genotype detection. The CC, CT and TT genotypes of C1236T accounted for 16.08% (64/398), 44.22% (176/398) and 39.70% (176/398). GG, GT, GA, TT and AT genotypes of G2677T/A accounted for 16.62%(66/397), 44.33%(176/397), 7.05%(28/397), 27.46%(109/397) and 4.54%(18/397). CC, CT and TT genotypes of C3435T accounted for 21.11%(84/398), 56.03%(223/398) and 22.86%(91/398) re?spectively. Hardy-Weinberg genetic equilibrium testing showed that polymorphisms of C1236T, G2677T/A and C3435T had group representation (P<0.05).②Eleven cases of HER-2 (2+) were excluded because they were not verified by FISH de?tection when performed molecular subtype of breast cancer. Luminal A subtype accounted for 41.90%(163/389), Luminal B subtype accounted for 32.65%(127/389), HER-2 over-expression subtype accounted for 13.62%(53/389) and triple nega?tive subtype accounted for 11.83%(46/389).③CT/TT genotype frequency of C3435T was significantly higher in breast can?cer patients with Luminal A subtype than that in breast cancer patients with HER-2 over-expression subtype and triple neg?ative subtype (χ2=12.011, P=0.001;χ2=13.976, P<0.001), while there was no statistical difference in C1236T and G2677T/A gene polymorphism between different molecular subtypes of breast cancer (P>0.05). Conclusion C3435T gene polymor?phism can explain more accurately heterogeneity of breast cancer. CT/TT genotype in different molecular subtypes of breast cancer may be more sensitive to drug treatment.

Objective Women with gestational diabetes mellitus (GDM) are at risk to develop Type 2 diabetes mellitus ( DM2).The aim of this study is to compare the effect of three diagnostic criteria on the prevalence of GDM.Methods 2864 pregnant women receiving obstetric care at 24 to 28 weeks of gestation at Peking University First Hospital,underwent the 75 g oral glucose tolerance test for routine GDM screening.The pregnancies were evaluated bythe American Diabetes Association (ADA 2004) Cuideline,the new criteria which was proposed by the International Association of Diabetes and Pregnancy Study Groups (IADPSG 2010) based on the HAPO study,not by the criteria of American College of Obstetricians and Chinese Obstetrics and Gynecology (6th edition 2005).Venous plasma glucose was measured by the IDMS-traceable glucose oxidase method.Results The mean age of the women was 30 years.590 women were diagnosed with GDM using the IADPSG criteria.According to the IADPSG standard,GDM diagnostic rate reached 20.6％.The diagnostic rate of new criteria was increased by 307％ and 199％ compared with the Chinese Obstetrics and Gynaecology (6th edition) and the old ADA standard,respectively.If increasing the number of abnormal glucose values in the IADPS standard to 2 or more,the number of positive cases dropped to 227 people.The diagnostic rate of GDM plummeted to 7.93％,similar with that of the old ADA diagnostic criteria (6.8％).Conclusions The diagnosis rate of GDM was significantly higher using the IADPSG criteria,due to more stringent glucose abnormality recommended by the IADPSG.
