      • Variants on ESR1 and their Association with Prostate Cancer Risk: A Meta-analysis

        Ding, Xiang,Cui, Feng-Mei,Xu, Song-Tao,Pu, Jin-Xian,Huang, Yu-Hua,Zhang, Jiang-Lei,Wei, Xue-Dong,Hou, Jian-Quan,Yan, Chun-Yin Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.8

        Background: Epidemiological studies evaluating the association of two variants rs9340799 and rs2234693 on estrogen receptor 1 (ESR1) with prostate risk have generated inconsistent results. Methods: A meta-analysis was here conducted to systematically evaluate the relationship of these two variants with prostate cancer susceptibility. Results: For rs9340799, heterozygosity of T/C carriers showed a significant increased prostate cancer risk with a pooled odds ratio (OR) of 1.34 (95% CI = 1.06-1.69) while homozygote C/C carriers showed an increased but not statistically significant association with prostate cancer risk (pooled OR = 1.29, 95% CI = 0.94-1.79). Compared to the homozygous TT carriers, the allele C carriers showed a 31% increased risk for prostate cancer (pooled OR = 1.31, 95% CI = 1.06-1.63). No significant association between the rs2234693 and prostate cancer risk was found with the pooled OR of 1.15 (95% CI = 0.97-1.39, T/C and C/C vs. T/T) under the dominant genetic model. Compared to the homozygote T/T carriers, the heterozygous T/C carriers did not show any significantly different risk of prostate cancer (pooled OR = 1.13, 95% CI = 0.94-1.36) and the homozygous C/C carriers also did not show a significant change for prostate cancer risk compared to the wide-type T/T carriers (pooled OR = 1.26, 95% CI = 0.98-1.62). Conclusion: These data suggested that variant rs9340799, but not rs2234693, on ESR1 confers an elevated risk of prostate cancer.

        Synthesis, Application, and Recovery of Alkali-Clearable Disperse Dyes Containing Azo Pyridone Structure

        Liang Jin,Tao Qian,Ren-Liang Wang,Tao Zhu,Wei-Guo Chen,Hua Jiang,Zhi-Hua Cui 한국섬유공학회 2022 Fibers and polymers Vol.23 No.4

        Carboxylic acid ester disperse dyes containing an azo pyridone structure have a high molar extinction coefficient,excellent washing color fastness, and simple synthetic methods. Dyes were readily synthesized through a conventional diazocoupling reaction between the reactant ethyl p-aminobenzoate and a coupling component containing an azo pyridonestructure. Subsequently, the molecular structures of the target products were characterized by FTIR, mass spectrometry,1H NMR, 13C NMR, UV-vis absorption spectroscopy, and elemental analysis. The synthesized dyes were used to dyepoly(ethylene terephthalate) fabric, and their washing and rubbing color fastness properties were tested and compared underdifferent post-treatment methods. Moreover, under the condition of alkali clearing, the relationships among different alkaliconcentrations and clearing effects were studied to determine the optimal alkali clearing process conditions for dyed fabrics,and the minimum alkali consumption required to obtain the best results was determined. It was found that carboxylic esterdisperse dyes containing an azo pyridone structure showed good dyeing performance and alkali-clearable properties onpolyester fibers. In addition, in hydrolyzate recovery, BaCl2 (salting out) can be used instead of acidification to recover thedye hydrolyzate, which has good environmental benefits.

        The Therapeutic Effects of Tectorigenin on Chemically Induced Liver Fibrosis in Rats and an Associated Metabonomic Investigation

        Xing-Xi Gao,Jun-Hua Wu,Da-Hua Shi,Yun-Xi Chen,Jiang-Tao Cui,Yu-Rong Wang,Chun-Ping Jiang 대한약학회 2012 Archives of Pharmacal Research Vol.35 No.8

        The aim of this study was to investigate the effects of tectorigenin on chemically induced liver fibrosis in rats. Liver fibrosis was induced in rats with carbon tetrachloride, a diet high in fat, cholesterol and alcohol in the drinking water. Our results indicate that tectorigenin treatment significantly inhibited the increases in the activities of alanine aminotransferase (ALT),aspartate aminotransferase (AST) and the increases in the serum levels of hyaluronate (HA), laminin (LN) and procollagen III N-terminal peptide (PIIIP); tectorigenin treatment also significantly inhibited the increases in the amount of collagen in the livers of the fibrogenic rats. Chemically induced liver fibrosis caused a drop in the serum albumin concentration and a decrease in the ratio of albumin to globulin (A/G). Tectorigenin caused a remarkable increase at a dose of 30 mg/kg, but only a slight increase at the lower doses. Tectorigenin was also able to inhibit the increase in the liver lipid peroxidation (LPO), as well as the decrease in the activities of liver superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), caused by liver fibrosis. In addition, we present a related metabolic profile determined, using a 1H NMR spectroscopy and multivariate pattern recognition techniques. The results were consistent with the pathological examination, liver function analysis and liver fibrosis marker analysis. Furthermore, tectorigenin does not cause acute toxicity.
