Sweetpotato starch thermal properties and its noodle quality were analyzed using a rapid predictive method based on near-infrared spectroscopy (NIRS). This method was established based on a total of 93 sweetpotato genotypes with diverse genetic background. Starch samples were scanned by NIRS and analyzed for quality properties by reference methods. Results of statistical modelling indicated that NIRS was reasonably accurate in predicting gelatinization onset temperature (T(o)) (standard error of prediction SEP=2.014 degrees C, coefficient of determination RSQ=0.85), gelatinization peak temperature (T(p)) (SEP=1.371 degrees C, RSQ=0.89), gelatinization temperature range (T(r)) (SEP=2.234 degrees C, RSQ=0.86), and cooling resistance (CR) (SEP=0.528, RSQ=0.89). Gelatinization completion temperature (T(c)), enthalpy of gelatinization (DeltaH), cooling loss (CL) and swelling degree (SWD), were modelled less well with RSQ between 0.63 and 0.84. The present results suggested that the NIRS based method was sufficiently accurate and practical for routine analysis of sweetpotato starch and its noodle quality.

AIMTo investigate the variation of CYP2C9 isoenzyme activity in the microbial model in response to inhibitors of CYP2C9.

METHODSUsing C. blakesleeana AS 3. 910 as a model strain, the impact of CYP2C9 inhibitors on the metabolites yields of CYP2C9 substrates was determined and the drug-drug interactions among CYP2C9 substrates were evaluated. Liquid chromatography-mass spectrometry was used to analyze biotransformation products.

RESULTSBenzbromarone decreased the yield of 4'-hydroxytolbutamide from 100% to 14.5%; sulfaphenazole decreased the yield of O-demethylindomethacin from 75.2% to 9.9%; valproic acid decreased the yield of 4'-hydroxydiclofenac from 98.6% to 2.7%, separately. Tolbutamide, indomethacin and diclofenac interacted with each other, resulting in the decreased formation of metabolites catalyzed by CYP2C9.

CONCLUSIONThree CYP2C9 inhibitors inhibit the activity of CYP2C9 isoenzyme in C. blakesleeana AS 3. 910 differently, and there are drug-drug interactions among CYP2C9 substrates.

The mechanisms involved in virus-induced severe hepatitis have not been fully elucidated.In this study,we investigated the role of gamma delta T cell receptors (γδ) T cells in the pathogenesis of fulminant viral hepatitis (FVH) induced by murine hepatitis virus strain 3 (MHV-3).The model of FVH was established by intraperitoneal injection of MHV-3 into Balb/cJ mice.The survival days of mice,and the serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were examined.The proportions ofγδ T cells in blood,spleen and liver,and cytokines secreted by hepatic γδ T cells were analyzed by flow cytometry.The function of hepatic γδ T cells was examined by cytotoxicity assay.Balb/cJ mice died in 3 to 6 days post MHV-3 infection,with severe hepatic necrosis and significant augmentation of serum ALT and AST levels.The proportions of γδ T ceils in blood,spleen and liver were significantly increased post MHV-3 infection,while those of the early activating molecule CD69-expressing γδ T cells and productions of cytokines tumor necrosis factor-alpha (TNF-α) and interferon-γ (IFN-γ) increased remarkably in the liver.These highly activated liver γδ T cells were cytotoxic to MHV-3-infected hepatocytes in vitro and this effect of liver γδ T cells against hepatocytes might involve the TNF-α and IFN-γ pathway.These results demonstrated that γδ T cells might contribute to the pathogenesis ofMHV-3-induced FVH through the effector cytokines TNF-α and IFN-γ.

Objective To explore the biological exposure limit of liver dysfunction induced by arsenic-coal burning, and screen sensitive biornarkers for its' liver dysfunction monitoring. Methods One hundred and eighteen subjects from the exposed area and 50 control from non-pollution area were studied. Their urinary and hair contents of arsenic were tested as exposure biomarkers by Ag-DDC assay. Total bile acid(TBA, detected by enzymatic cycling method), glutathione S-transferase (GSTs, detected by chemical colorimetry) and γ-glutamyl transpeptidase (γ-GT, detected by colorimetry of diazotization reagent) were used as biomarkers indicating liver cell damage. were used as liver fibrosis biomarkers. The benchmark dose (BMD) and the lower confidence limit of benchmark dose(BMDL) of urinary and hair arsenic were calculated. Sensitivity of each biomarker was estimated according to the BMD and BMDL value. Results The geometric mean of urinary and hair arsenic(98.50 mg/kg Cr, 7.42 mg/kg) μg/L) in the exposed group were significantly higher than urinary and hair arsenic (22.98 mg/kg Cr, 1.28 mg/kg) and each biomarker in the control group(4.63 μmol/L, 13.76 U/L,36.45 U/L,54.62 μg/L,74.45 μg/L,54.81 μg/L, P<0.01). Significant dose-effect relationship existed between urinary and hair arsenic contents and each biomarker. BMD and BMDL value of urinary arsenic was 49.53-101.96 mg/kg Cr and 39.02-70.15 mg/kg Cr, respectively. Those of hair arsenic were 3.04-5.02 mg/kg and 2.36-3.25 mg/kg, respectively. According to BMD and BMDL value of urinary and hair arsenic, the sensitivity of biomarkers decreased in the order of GSTs, TBA and Conclusions According to the lowest BMD and BMDL of urinary and hair arsenic, averaged reference value of urinary and hair arsenic in the local normal population, we suggest urinary 35.0 mg/kg Cr and hair 2.5 mg/kg as their biological exposure limits for those with liver dysfunction induced by arsenic-coal burning. GSTs, TBA, γ-GT and HA, Ⅳ. C, PC-Ⅲ can respectively reflect liver cell damage and liver fibrosis caused by arsenic-coal burning in different degrees, among which, GSTs and HA are the most sensitive biomarkers respectively for liver cell damage and liver fibrosis.

OBJECTIVETo determine the genetic diversity of Cistanche species.

METHODTwo populations of Cistanche deserticola and four populations of C. tubulosa were analyzed by random amplified polymorphic DNA (RAPD) markers.

RESULTA total of 76 and 87 loci were amplified using 10 random primers each other. The average percentage of polymorphic loci of C. deserticola was 47.37%. The PPL were 39.47% and 35.53% for two populations. Average Nei's gene diversity was 0.1358, Shannon' s genetic diversity was 0.2072, and Gst was 0.2546. The average PPL of C. tubulosa was 27.59%. It was 19.54% to 25.29% in different populations and Andi'er population had the highest. Average Nei's gene diversity was 0.0823, and Shannon' s genetic diversity was 0.125 8, Cst was 0.175 5.

CONCLUSIONThe diversity of Cistanche deserticola is higher than that of C. tubulosa, but both has differentiation among populations, C. deserticola has already separated itself into two different ecotypes.

OBJECTIVETo explore the differences of metabolic footprint in the conditioned culture medium of placental explants between early-onset and late-onset severe preeclampsia.

METHODSIn 13 cases of early-onset severe preeclampsia and 14 cases of late-onset severe preeclampsia, the placentas were sampled at the surface of the maternal placenta. High performance liquid chromatography-mass spectrometry (HPLC-MS) was used to determine the differences in the metabolites in the conditioned culture medium of the placental villous explants cultured in 6% atmospheric O(2) for 96 h. Standard samples were used to establish the tryptophan and kynurenine chromatography library by HPLC-MS to analyze the concentration of tryptophan and kynurenine in the conditioned culture medium.

RESULTSThirty-six metabolites showed statistically significant differences between early-onset and late-onset severe preeclampsia (P<0.05). The concentration of kynurenine was significantly higher in early-onset severe preeclampsia than in late-onset severe preeclampsia (P<0.05).

CONCLUSIONEarly-onset and late-onset severe preeclampsia may have different pathogeneses. By detecting the concentration of metabolites, metabolomic strategies provide a new means for predicting the onset time of severe preeclampsia.
