Objective To investigate the changes of serum levels of sex hormone binding globulin (SHBG),free testosterone index (FTI) and insulin resistance; and to investigate the relationship among them and prevalence of gestational diabetes mellitus (GDM) and hypertensive disorder complicating pregnancy (HDP) in polycystic ovarian syndrome (PCOS) women during pregnancy. Methods Serum samples of 32 PCOS women and 32 non-PCOS women were collected during their gestational age from 12 to16 weeks.Serum levels of total testosterone,SHBG and insulin were detected.Free testosterone index (FTI) and homeostasis model assessment for insulin resistance (HOMA-IR) were calculated.Risk factors of GDM and HDP were analyzed by stepwise logistic regression.Data of two groups were compared with t test or Chi square test. Results Serum fasting insulin [(8.0±1.5) mU/L vs (7.1±1.5) mU/L,t=2.32,P<0.05],FTI [0.96 (0.52-1.41) vs 0.61 (0.40-0.79),t=3.02,P<0.05],HOMA-IR levels [1.53±0.32 vs 1.36±0.36,t=2.04,P<0.05] and total testosterone [2.95 (1.61-4.40) nmol/L vs 2.15 (1.50-2.80) nmol/L,t=2.55,P<0.05] were higher in PCOS group than in control group; and SHBG level [325 (312-355) nmol/L vs 360 (347-373) nmol/L,t=4.13,P<0.05] was lower in PCOS group than in control group.Cesarean section rate (84% vs 50%,x2 =8.58,P<0.01) and HDP incidence (25% vs 3%,x2=4.65,P<0.05) were higher in PCOS group than in control group. SHBG level [(293 ±42) nmol/L] of PCOS women who complicated with GDM (n=6) was significantly lower than that [(333±40) nmol/L] of those who did not (n=26),t=2.22,P<0.05.Serum total testosterone [(4.34±1.29)vs (2.49±1.44) nmol/L,t=3.23,P<0.05] and FTI [1.42±0.52 vs 0.81±0.59,t=2.61,P<0.05] were significantly higher in PCOS women complicated with HDP (n=8) than those of the PCOS women who did not (n=24).Stepwise logistic regression analysis showed that SHBG was the risk factor of GDM (OR=0.98,95%CI:0.96~1.00,P<0.05); FTI was the risk factor of HDP in PCOS women (OR=5.53,95%CI:1.20~25.61,P<0.05). Conclusions FTI and SHBG levels could be predictors for GDM and HDP in PCOS women during their pregnancies.

Abstract] Objective To establish an assay for the detection of porcine parvovirus ( PPV) and to verify its application for monitoring cells used for production.Methods A pair of primers and one probe were designed according to the conserved sequence encoding non-structural protein 1 (NS1).Based on the designed primers, a real-time fluorescent quantitative PCR assay for the detection of PPV was developed. Several parameters including the linearity, precision, minimum detection limit and anti-interference of the established assay were evaluated.A stock of PPV strains was prepared by infecting swine testicle ( ST) cells with PPV strains.An assay for the detection of PPV infection was developed by using ST cells as sensitive cells.A combined ST cell infection-PCR test was developed by combining the ST cell infection assay with the real-time fluorescent quantitative PCR assay.The sensitivity of ST cell infection-PCR test was analyzed.The cell samples used for production of biological products were detected by using the established assay.Results The real-time fluorescent quantitative PCR assay was specific for the detection of PPV without cross-reaction to other species of parvovirus virus, SV40 virus and other porcine viruses.The linear range of the assay was 1×109-1×104 copies/μl with a R2 value more than 0.98.The sensitivity of the real-time quantitative PCR assay was 1×104 copies/μl.Both of the intra-and inter-coefficient of variation (CV) were less than 5%in Ct values.The intra-and inter-CV in copies of detection were 5%-15% and 30%-40% respectively.The minimum detection limit of the real-time fluorescent quantitative PCR assay was 1CCID50/ml.The PPV strains were detected in cell samples with no interference.The sensitivity of ST cells infection-PCR test was 0.01CCID50/ml.All of the 22 cell samples were negative for PPV by using the real-time fluorescent quanti-tative PCR assay.Conclusion The real-time fluorescent quantitative PCR and the ST cell infection-PCR test for the detection of PPV in cells were established successfully.The application of the two assays was conducive to further enhance the safety of using cells for production and therapy.

Water soluble extract (WSE) is an important index for the quality evaluation of Astragali Radix (AR). In this study, the WSE of the wild AR from Shanxi province (SX) and the cultivated AR from Gansu Province (GS) were compared. The WSEs of two types of AR were determined according to the appendix of Chinese pharmacopoeia. Then the WSEs were subjected to NMR analysis, and the obtained data were analyzed using HCA, PCA, OPLS-DA, microarray analysis, and Spearman rank analysis. In addition, the Pearson correlation of differential metabolites were also calculated. The results showed that the WSE content of GS-AR (37.80%) was higher than that of SX-AR (32.13%). The main constituent of WSE was sucrose, and other 18 compounds, including amino acids, organic acids, were also detected. Multivariate analysis revealed that SX-AR contained more choline, succinic acid, citric acid, glutamate, taurine and aspartate, while GS samples contained more sucrose, arginine and fumaric acid. In addition, the Pearson correlations between different metabolites of the two types of AR also showed apparent differences. The results suggested that the WSE of two types of AR differs not only in the content, but also in the chemical compositions. Thus, the cultivation way is important to the quality ofAR. This study supplied a new method for the comparison of extract of herbal drugs.
