Objective To establish the standard for quality control ofQingyan Granule. Methods The chief components of the preparation, Sophora Tonkinensis radix et rhizoma, Adenophorae radix, Lonicera japonica caulis, and Ophiopogonis radix were identified by TLC qualitatively. The contents of licorice glycosides and glycyrrhizic acid were determined by HPLC. The separation was performed on Thermo Syncronis C18 column (4.6 mm×250 mm, 5μm) with mobile phase consisted of acetonitrile with 0.05% phosphoric acid solution (A)-0.05% phosphoric acid solution (B), and gradient elution (0-8 min, 19%A;8-35 min, 19%→50%A). Detection wavelength was 237 nm, and flow rate was 1 mL/min.Results The spots in TLC were clear. There were spots with same color on the corresponding location of reference substance and reference herbal, negative control without interference. The linear range for licorice glycosides was 0.05-0.5μg (r=0.999 9). The average recovery was 99.97%, RSD=1.74% (n=9). The linear range for glycyrrhizic acid was 0.1-2μg (r=0.999 9). The average recovery was 99.74%, RSD=1.28% (n=9). Conclusion The method is simple, accurate, with high reproducibility, which can be used for quality control ofQingyan Granule.

OBJECTIVETo study the molecular mechanism of Yangjing Zhongyu Decoction (YZD) n-butanol extracts (ZDC) and ethyl acetate extracts (YSYZ) in reducing androgen in porcine granulose cells by mitogen-activated protein kinase (MAPK) pathway.

METHODSPorcine granulose cells were isolated and cultured. They were inoculated by MAPK inhibitor PD98059 at different concentrations, and then they were divided into the blank control group (0), 1, 3, 10, and 25 micromol/L groups. After 24-h culture the cytochrome P450c17a (CYP17) mRNA expression level was detected using Real-time fluorescent quantitative PCR. Contents of androgen (testosterone) in the supernate were detected using RIA and optimal PD98059 concentration screened. After intervened by 10 micromol/L PD98059 for 24 h, the culture solution was intervened by effective ingredients of with or without YZD or YSYZ at various concentrations (0, 1 , 5, 25, 50 mg/mL) at various time points (3, 6, 18, 24 h). Expression levels of p-ERK1/2, c-Fos and CYP17 were detected by Western blot. Testosterone content in the supernate was determined by radioimmunoassay (RIA).

RESULTSTen pLmol/L PD98059 could obviously decrease p-ERK1/2 protein expression and increase CYP17 mRMA expression, and elevate testosterone content in the supernate (P < 0.05). ZDC and YSYZ at 25 ng/mL could increase p-ERK1/2 protein expression and c-Fos levels, and reduce CYP17 protein expression, and lower testosterone content in the supernate after 6-h intervention (P < 0.01).

CONCLUSIONEffective ingredients of YZD could reduce androgen production in porcine granulose cells through increasing activities of MAPK.

Aflatoxins produced primarily by two closely related fungi, Aspergillus flavus and Aspergillus parasiticus, are mutagenic and carcinogenic in animals and humans. Of many approaches investigated to manage aflatoxin contamination, biological control method has shown great promise. Numerous organisms, including bacteria, yeasts and nontoxigenic fungal strains of A. flavus and A. parasiticus, have been tested for their ability in controlling aflatoxin contamination. Great successes in reducing aflatoxin contamination have been achieved by application of nontoxigenic strains of A. flavus and A. parasiticus in fields of cotton, peanut, maize and pistachio. The nontoxigenic strains applied to soil occupy the same niches as the natural occurring toxigenic strains. They, therefore, are capable of competing and displacing toxigenic strains. In this paper, we review recent development in biological control of aflatoxin contamination.

Objective To analyze the distribution characteristics of blood uric acid and its relationship with the risk factors of metabolic syndrome in Uygur.Methods The questionnaire,anthropometric measurements,and biochemical detection were carried out in 4 428 healthy Uygur subjects in Xinjiang Urumqi and Kashi hospitals.Results (1) The prevalences of hyperuricemia and metabolic syndrome were 21.3 ％ and 8.2％,respectively.With the increased blood uric acid level,the incidences of coronary heart disease,hyperglycemia,hypertension,central obesity,and dyslipidemia were raised.Blood pressure,blood glucose,HbA1c,triglyceride,total cholesterol,apolipoprotein A,low density lipoprotein-cholesterol,body mass index (BMI),and waist to hip ratio (WHR) were increased with increased uric acid level,while high density lipoprotein-cholesterol was decreased.(2) The incidence of hyperuricemia was increased further when the number of metabolic syndrome components was accumulated (P＜0.01).With the increase of uric acid level,the prevalence of metablic syndrome gradually raised (P＜0.01).(3) Multiple logistic regression analysis showed that WHR (OR =7.639,95 ％ CI 1.744-33.466),coronary heart disease (OR =2.784,95 ％ CI 1.718-4.510),hyperuricemia (OR =2.155,95 ％ CI 1.457-3.188),smoking (OR =1.437,95％ CI 1.071-1.927),family history of metabolic diseases (OR =1.333,95％ CI 1.044-1.703),occupational pressure (OR =1.290,95 ％ CI1.021-1.631),and BMI (OR =1.146,95 ％ CI 1.112-1.181) were the risk factors of metabolic syndrome.Exercise (OR=0.472,95％ CI0.370-0.604) and low salt diet (OR=0.793,95％ CI0.662-0.949) were the protective factors.Conclusion Serum uric acid level is correlated with a variety of metabolic parameters.With the increased uric acid level,the risk of multiple metabolic abnormality was increased.Comprehensive prevention and control should be taken for the reduction of the risk factors and much attention should be paid to the adverse effects of hyperuricemia.

The association between the polymorphism of SLC17A1 gene and hyperuricemia in Uyghur population in Xinjiang region was explored by Chi-square test.A total of 1 024 patients with hyperuricemia and 1 033 healthy volunteers were included.The genotype frequencies of CC,CT,and Tr in hyperuricemia and healthy controls were 24.9％,53.14％,21.96％ and 29.7％,47.52％,22.77％,respectively.There was statistical difference in SLC17A1 rs9467596 genotype frequencies between hyperuricemia cases and controls (x2 =7.492,P =0.024).CT genotype could increase the risk of hyperuricemia compared with CC genotype (OR =1.334,95％ CI 1.082-1.644).No statistical significance among the genotypes was found in age,body mass index,blood pressure,blood glucose,triglyceride,total cholesterol,High-density lipoprotein-cholesterol,low-density lipoprotein-Cholesterd,blood urea nitrogen,and Creatinine.The polymorphism of rs9467596 in SLC17A1 may be a genetic marker to assess risk of hyperuricemia among Xinjiang Uyghur population.

Objective To identify the potential association of transcription factor 7-like 2(TCF7L2 polymorphisms with type 2 diabetes mellitus in Uygur population of Xinjiang region .Methods In this case-control study ,819 ca-ses of type 2 diabetes mellitus patients were recruited in case group and 731 healthy individuals were selected as control.5 mL of blood sample were collected from each subject .The polymorphism was examined by matrix-assis-ted laser desorption/ionization-time of flight ( MALDI-TOF) and the OR value (95%CI) was evaluated by Logistic Regression Method to analyze the relationship between susceptibility to type 2 diabetes mellitus and different geno-types.Results In case group, the frequencies of TC, CC genotype and C allele at rs7901695 were higher than the corresponding frequencies in control group (P<0.05).The interaction between TCF7L2 and environment risk factors did not contribute to the occurrence of the type 2 diabetes mellitus .Conclusions The polymorphisms of rs7091695 in TCF7L2 but not rs7085532 in TCG7L2 may be associated with type 2 diabetes mellitus in Uygur pop-ulation in Xinjiang region .
