Objective To study metabolism of glucose and lipidin patients with hyperandrogenism and analyze the risk of their cardiovascular disease.Methods Object of study:firstly,choosed 118 cases of women of reproductive age from April 2013 to July 2014.Then detected their serum Testosterone (T),Estradiol (E2),fasting plasma Glucose (FPG),fasting plasma insu-lin (FINS),triglycerides (TG),total cholesterol (TC),high-density lipoprotein cholesterol (HDL-C),low-density lipopro-tein cholesterol (LDL-C),lipoprotein (a),body mass index (BMI).Finally,divided them into different groups and analyzed the results using SOSS19.0 software and two independent samples t-test statistical method.Results BMI,T,FPG,HOMA-IR and TG were significantly more higher (P <0.05)in the group of hyperandr-ogenism than in the group of normal con-trol.However,E2,TC,HDL-C,LDL-C and LP(a)had no significant difference (P >0.05)in statistics between the group of hyperandrogenism and the group of normal control.Hyperandr-ogenism group was divided into PCOS group and non-PCOS group according to etiology.In those two groups,BMI,T,E2,FPG,HOMA-IR,TG,TC,HDL-C,LDL-C and LP(a)had no significant difference in statistics (P >0.05).According to the definition of obesity adults in china,78 patients with hyperan-drogenism were divided into 2 group,one with BMI normal (BMI<24 kg/m2 )and the other group with overweight and obe-sity (BMI≥24 kg/m2 ).In group with overweight and obesity,BMI,T,FPG,HOMA-IR,TG,TC,LDL-C and LP (a)were significantly higher than the group with BMI normal (P <0.05),moreover,HDL-C was significantly lower than the group normal (P <0.05).E2 had no significant difference in statistics between the two groups (P >0.05).Conclusion Investiga-tion of the relation between hyp-erandrogenism and metabolism of glucose and lipid,can not only practically guide life style and drug therapy,but also prevent cardio-vascular disease.

The present study used the experimental patterns of Go/No Go and no motion contingent negative variation (CNV) task into the research in order to study whether the CNV can express the implication of expectation. Through comparing the CNV under different conditions, the data collected from experiment showed that the key to evoked CNV was close to the warning signal and command signal. Whether the command signal was related to the task would impact on the amplitude of the CNV. This characteristics responses to the subjects' expectation. On this basis, CNV can be used as the electrophysiological index for the reflection of expected value in the conditions of this experiment.

This study sought to reveal the difference of brain functions at resting-state between subjects with sub-health and normal controls by using the functional magnetic resonance imaging (fMRI) technology. Resting-state fMRI scans were performed on 24 subjects of sub-health and on 24 healthy controls with gender, age and education matched with the sub-health persons. Compared to the healthy controls, the sub-health group showed significantly higher regional homogeneity (ReHo) in the left post-central gyrus and the right post-central gyrus. On the other hand, the sub-health group showed significantly lower ReHo in the left superior frontal gyrus, in the right anterior cingulated cortex and ventra anterior cingulate gyrus, in the left dorsolateral frontal gyrus, and in the right middle temporal gyrus. The Significant difference in ReHo suggests that the sub-health persons have abnormalities in certain brain regions. It is proved that its specific action and meaning deserves further assessment.

Objective To observe the effect of Jiaweibugan decoction on c-jun mRNA expression of sciatic nerve in experimental di-abetic rat and explore the preventive and therapeutic effects of Jiaweibugan decoction on peripheral neuropathy in experimental diabetic rats. Methods The diabetic rat model, was established by streptozotocin (STZ). The rots were killed on the 4th or 8th week from the beginning of treatment, and c-jun mRNA of sciatic nerve was detected by reverse-transcriptase polymerase chain reaction (RT-PCR). Serum SOD was determined by xanthine oxidase method. Results The results of RT-PCR showed that c-jun mRNA expression of the model group on the 4th or 8th week was higher than that of the normal control group (P <0.05) , while those in model rats treated by Jiaweibugan decoction were markedly lower than those in non-treated model rats(P <0.05). The results showed that SOD of the model group on the 4th or 8th week was lower than that of the normal control group (P < 0.05) , while those in model rats treated by Jiaweibugan decoction were markedly higher than those in non-treated model rats(P < 0.05). Conclusion Jiaweibugan decoction has a preventive and therapeutic effect on peripheral neuropathy in experimental diabetic rats.

Objective To investigate the efficacy,safety of allogeneic hematopoietic stem cell transplantation(Allo-HSCT)in lupus mice.Methods22BXSB was pre-treated with myleran and cyclophosphamide,12BXSB were treated with CTX and prednisone as the control group.Peripheral blood stem cells of doner mouse(C57BL/6)after mobilizing with G-CSF were infused into recipients after pretreatment.Hematopoietic and immune reconstitution after transplantation were measured by blood cell analysis and flowcytometry.Recipients' renal pathological changes were measured with direct immunofluorescence after transplantation,proteinuria and anti-dsDNA antibody were also determined.Complications and mortality were compared between the two groups.Recipients'genetic map was analysed with PCR.Results Recipients'complete chimerism was observed after60days of transplantation.The lowest value of WBC declined to0.2?0.1?10 9 /L in Allo-HSCT group.The duration of WBC increased from the lowest value up to1.0?10 9 /L was47.5?12.8d in Allo-HSCT group.Early immune reconstitution could not be found in Allo-HSCT group.After transplantation reduction of proteinuria occurred in95.5%BXSB,anti-ds-DNA antibody turned to negative in54.5%BXSB,decrease of kindey immunofluorescence in90.9%BXSB,there was a significant difference between the two groups.There was no significant difference in the incidences of complication of bleeding,pneumonia and mortality between the Allo-HSCT group and the control group.Conclusions Allo-HSCT is an effective treatment method for lupus mice.It may be helpful in improving proteinuria and anti-dsDNA antibody and renal pathological changes of lupus mice.But the incidences of complication and mortality related to transplantation in Allo-HSCT group are higher than those in control group,so the value of Allo-HSCT in the treatment lupu mice has to be further studied.

Objective To explore the peptides that can mimic the blood type A antigen and evaluate the anti-A antibody detection value of these peptides.Methods The anti-A monoclonal antibodv (NaM87-1F6)was used to panning the phage clones from a phage display 12-mer peptide library.Positive clones were identified by phage ELISA,phage mieropanning methods.Phage DNA Was sequenced and the corresponding peptide sequences were deduced.Agglutination inhibition test WaS performed to assess the ability of phage clones to inhibit the binding between the type A red blood cell and the anti-A antibody. ABO-ELISA based on the selected peptides was compared with classical haemagglutination test jn the detection of senlm anti-A antibody.Results Seven positive clones were chosen after panning,phage ELISA and phage micropanning.Six clones displayed peptide EYWYCGMNRTGC(C5),the other one displayed peptide QIWYERTLPFTF(C17).The phages displaying the selected peptides could specifically inhibit agglutination of type A red blood cells(RBCs)by anti-A antibodies.In the ABO-ELISA based on C5 and C17,the receiver operating characteristic(ROC)Curve showed that area under curve(AUC)were 0.889 (P=0.000),0.75l(P=0.000)respectively.The Spearman correlation Coeffieient between the ABO-EliSA value and the antibody titer derived from haemagglutination assay were 0.743(P<0.01),0.664(P<0.01)respectively.As for C5,0.300 was the best cut-off for ABO-ELISA with 82.2% sensitivity and 83.3% specificity.As for C17,the sensitivity and specificity of ABO-ELISA was 68.9% and 63.3% respectively when the cut-off value was 0.250.Conclusions The peptides EYWYCGMNRTGC and QIWYERTLPFTF can mimic the blood type A antigenic epitope.ABO-ELISA based on these peptides has the potential for the detection of anti-A antibody.
