A total of 451 Mycobacterium tuberculosis isolates which were collected from patients with tuberculosis(TB) in the Zunyi region between Jan, 2013 and Aug, 2015, be used to determine antibiotic susceptibility patterns against 12 anti-TB drugs: 4 first-line and 8 second-line (gatifloxacin, levofloxacin, moxifloxacin, para-aminosalicylic acid, amikacin, capreomycin, kanamycin, and prothionamide) drugs.Results showed that 1.9% of new and 20.7% of previously treated cases were multidrug-resistant TB (MDR-TB) ; and 0.9% of new and 5.2% of previously treated cases were extensively drug-resistant TB (XDR-TB).In addition, 18.2% of MDR-TB cases (10 out of 55) were XDR-TB, which is higher than the average numbers in China (about 8%) and in the world (9.0%).

"顿悟"是中国传统文化中不可或缺的哲学思想,也是二十余年来中国美学界屡有提及的重要学术范畴.顿悟美学是禅宗美学的核心要义,顿悟以及以顿悟为核心的诸美学范畴一起构建了禅宗美学的主要研究域,同时,顿悟美学也是儒学和道学的重要组成部分。作者认为“顿悟”学说与美学中的灵感说颇近。朱光潜明确认为“灵感就是悟”，这一点后来被祁志祥扩展开来，他从悟道成佛的认识论出发，认为渐顿说具有艺术灵感的色彩，因而启发孕育了
目的：研究氧化苦参碱(OMT)对醛固酮(ALD)诱导心肌成纤维细胞(CFs)增殖的作用,并分析其对p38丝裂素活化蛋白激酶(p38MAPK)表达的影响.方法：采用胰酶消化法和差速贴壁法分离纯化1～3d新SD生大鼠CFs做原代培养,建立ALD诱导CFs增殖模型.ALD诱导CFs量效实验分为：空白组(无血清DMEM)、ALD1×10-10ALDmol·L-1、1×10-9ALDmol·L-1、1×10
目的：利用大鼠在体循环灌流模型,采用UPLC-ESI-MS/MS测定灌流液中头花蓼提取物主要活性指标成分没食子酸、原儿茶酸、杨梅苷、金丝桃苷和槲皮苷的含量,并计算出吸收速率常数和累积吸收百分率.方法：分别考察不同药物浓度、不同肠段、胆汁及p-糖蛋白抑制剂对头花蓼提取物中没食子酸等成分在大鼠体内的吸收机制的影响.结果：头花蓼提取物中没食子酸、原儿茶酸、杨梅苷、槲皮苷在高浓度下存在饱和现象(P＜0.0
目的：动脉粥样硬化 (atherosclerosis , AS )是一种常见的血管疾病，血管内皮受损为其起始环节。研究阿司匹林(Aspirin,1mM)对氧化低密度脂蛋白(ox-LDL)诱导的人主动脉内皮细胞(HAEC)损伤的保护作用并探讨其对p-Akt/eNOS信号系统的影响.方法：体外传代培养HAECs,3-6代HAECs用于实验研究.实验分为空白对照组(Control)、模型组(Model)
目的：为了避免贵州宽叶缴草药用植物的枯竭，势必要对药材进行规范化栽培种植(GAP)。采用正交设计法安排RAPD体系优化试验，建立可用于黔产宽叶缘草RAPD分析的最佳反应体系，并进行遗传多样性分析.方法：采用L16(45)正交设计,确立宽叶缬草最佳RAPD反应体系;通过对宽叶缬草基因组DNA样本进行RAPD扩增,分析样本Neis多样性指数(H)、Shannons多样性指数(Ⅰ)以及Jaccard遗传
