4Polymorphisms of MTHFD,plasma homocysteine levels, and risk of gastric cancer in ahigh-risk Chinese population显示文摘Purpose:Accumulative evidence suggests that folate has a protective effect on gastric cancer. The methylenetetrahyd-rofolate dlehydrogenase(MTHFD) plays an important role in folate and homocysteine metabolisms, and polymorphisms of MTHFD may result in disturbance of the folate-mediated homocysteine pathway. The aim of this study is to test the hypothesis that genetic variants of MTHFD and plasma homocysteine levels are associated with risk of gastric cancer and modulated by genotypes of methylenetetrahydrofolate reductase(MTHFR). Experimental Design: We genotyped G1958A and T401C in MTHFD and C677T in MTHFR and detected total plasma homocysteine(tHcy) levels in a case-control study of 589 gastric cancer cases and 635 cancer-free controls in a high-risk Chinese population. Results:The variant genotypes of MTHFD 1958AA and 401CC were associated with a significantly increased risk of gastric canceradjusted odds ratio(OR), 2.05; 95% confidence interval(95% CI),1.34-3.13 for 1958AA; adjusted OR,1.43; 95% CI,1.14-1.80 for 401CC compared with 1958GG/GA and 401TT/TC genotypes, respectively. Both of the effects were more evident in the subjects carrying MTHFR 677CT/TT genotypes. The average tHcy level was significantly higher in gastric cancer cases than in controls(P < 0.01), and the upper quartile of tHcy (> 13.6 mu mol/L) was associated with an 82% significantly increased risk of gastric cancer, compared with the lowest quartile of tHcy(<= 8.0 pmol/L;adjusted OR,1.82; 95% CI,1.20-2.75). Conclusions:The strong associations between MTHFD variants and the plasma tHcy levels and gastric cancer risk suggest, for the first time, a possible gene-environment interaction between genetic variants of folate-metabolizing genes and high tHcy levels in gastric carcinogenesis.Wang, L.

7Distribution of pericellular matrix molecules in the temporomandibular joint and their chondroprotective effects against inflammation显示文摘The objectives of this study were to(1) determine the distribution and synthesis of pericellular matrix(PCM) molecules(collagen VI, collagen IV and laminin) in rat temporomandibular joint(TMJ) and(2) investigate the effects of PCM molecules on chondrocytes against inflammation in osteoarthritis. Four zones(fibrous, proliferating, mature and hypertrophic) of condylar cartilage and three bands(anterior, intermediate and posterior) of disc were analysed by immunohistochemistry for the presence of PCM molecules in rat TMJs. Isolated chondrocytes were pre-treated with PCM molecules before being subjected to interleukin(IL)-1β treatment to stimulate inflammation. The responses of the chondrocytes were analysed using gene expression, nitric oxide release and matrix metalloproteinase(MMP)-13 production measures. Histomorphometric analyses revealed that the highest areal deposition of collagen VI(67.4%), collagen IV(45.7%) and laminin(52.4%) was in the proliferating zone of TMJ condylar cartilage. No significant difference in the distribution of PCM molecules was noted among the three bands of the TMJ disc. All three PCM molecules were expressed intracellularly by chondrocytes cultured in the monolayer. Among the PCM molecules, pre-treatment with collagen VI enhanced cellular proliferation, ameliorated IL-1β-induced MMP-3, MMP-9, MMP-13 and inducible nitric oxide synthase gene expression, and attenuated the downregulation of cartilage matrix genes, including collagen I, aggrecan and cartilage oligomeric matrix protein(COMP). Concurrently, collagen VI pretreatment inhibited nitric oxide and MMP-13 production. Our study demonstrates for the first time the distribution and role of PCM molecules, particularly collagen VI, in the protection of chondrocytes against inflammation.Wern Cui Chu Shipin Zhang Timothy J Sng Yu Jie Ong Wen-Li Tan Vivien Y Ang Casper B Foldager Wei Seong Toh 2017International Journal of Oral Science2017,9,1:5
8In vitro Ruminal Gas Production Kinetics of Four Fodder Trees Ensiled With or Without Molasses and Urea显示文摘This study investigated if the addition of urea (U), molasses (M) or their 1:1 (v/v) mixture during ensiling increases the nutritional value of forage from four fodder trees (Prunus persica, Leucaena esculenta, Acacia farnesiana, and Prunus domestica). Forage samples of fodder trees were collected in triplicate (three individual samples of each species) and subjected to an in vitro gas production (GP) procedure. Fermentation at 24 h (GP 24), short-chain volatile fatty acids (SCFA), and microbial crude protein production (MCP), in vitro organic matter digestibility (OMD), metabolizable energy (ME) and dry matter degradability (DMD) were estimated. Forage samples were incubated for 72 h in an incubator at 39oC and the volume of GP was recorded at 2, 4, 6, 8, 10, 12, 24, 48, and 72 h of incubation using the reading pressure technique. The rumen fermentation profiles were highest for P. persica, which showed the highest (P<0.0001) DMD, ME, OMD, SCFA, GP 24 and MCP. On the other hand L. esculenta had the lowest (P<0.0001) DMD, SCFA, MCP; P. domestica had the lowest (P<0.0001) OMD. The addition of M to silage increased (P<0.0001) ME and OMD, as well as GP. However, the addition of U and the mixture of U and M reduced (P<0.0001) DMD, ME, OMD, SCFA, GY 24 and MCP. These results show that P. persica has the highest nutritive value and L. esculenta the lowest for ruminants. Additionally, the addition of M to forage from fodder trees increases rumen GP and fermentation, which may improve nutrient utilization in ruminants.Abdelfattah Z M Salem ZHOU Chuan-she TAN Zhi-liang Miguel Mellado Moises Cipriano Salazar Mona M M Y Elghandopur Nicholas E Odongo 2013Journal of Integrative Agriculture2013,12,7:3

10治疗 幽门螺杆菌根治后应用质子泵抑制剂可能增加胃癌发病风险显示文摘背景 幽门螺杆菌感染是胃癌发生最常见的诱因。幽门螺杆菌根治是否能降低或消除胃癌发病风险取决于根治时的风险。对于有黏膜损害和胃酸过少者,幽门螺杆菌根治可恢复泌酸。幽门螺杆菌根治后应用质子泵抑制剂(PPI)可极度减少胃酸分泌。然而,幽门螺杆菌根治后应用PPI对于胃癌发生风险的影响仍不清楚。Mimi Chang Tan David Y Graham 霍永丰(译) 2018英国医学杂志中文版2018,21,11:3
