| 1 | Risk factors for tuberculosis after gastrectomy in gastric cancer显示文摘AIM: To examine incidence of tuberculosis(TB) in gastrectomy patients and investigate the risk factors for developing TB after gastrectomy in patients with gastric cancer.METHODS: A retrospective cohort study of gastrectomy patients with gastric cancer was performed at a university-affiliated hospital in Seoul, South Korea between January 2007 and December 2009. We reviewed patient medical records and collected data associated with the risk of TB, surgery, and gastric cancer. Standardized incidence ratios(SIRs) of TB were calculated to compare the incidence of TB in gastrectomy patients with that in the general Korean population, and risk factors for TB after gastrectomies were analyzed.RESULTS: Among the 1776 gastrectomy patients, 0.9%(16/1776) developed post-gastrectomy TB, with an incidence of 223.7 cases per 100000 patients per year. The overall incidence of TB in gastrectomy patients, adjusted by sex and age, was significantly higher thanthat in the general population(SIR = 2.22, 95%CI: 1.27-3.60). Previous TB infection [odds ratio(OR) = 7.1, P < 0.001], lower body mass index(BMI)(kg/m2; OR = 1.21, P = 0.043) and gastrectomy extent(total gastrectomy vs subtotal gastrectomy)(OR = 3.48, P = 0.017) were significant risk factors for TB after gastrectomy in a multivariate analysis.CONCLUSION: TB incidence after gastrectomy is higher than that in the general population. Previous TB infection, lower BMI, and total gastrectomy are risk factors for TB after gastrectomy in patients with gastric cancer. | Won Jai Jung Young Mok Park Joo Han Song Kyung Soo Chung Song Yee Kim Eun Young Kim Ji Ye Jung Moo Suk Park Young Sam Kim Se Kyu Kim Joon Chang Sung Hoon Noh Ji Yeong An Young Ae Kang | 2016 | World Journal of Gastroenterology2016，22，8： | 3 |

| 9 | 高合金无取向电工钢的磁各向异性和织构显示文摘本文研究了无取向电工钢中,添加合金对磁各向异性的影响。锡和锑可提高磁感应强度并且降低铁损,但是增加了磁感应强度的各向异性,并且减弱了铁损的各向异性。用织构因子评价织构的影响,织构因子可表示成立方织构和高斯织构的体积分数总和与γ纤维织构体积分数之比。铁损的磁各向异性与织构因子成反比,磁感应强度与织构因子成正比。 | Sam Kyu CHANG 张怀军(译) 兰岳光(校) | 2008 | 现代冶金(内蒙古)2008，，3： | 0 |
