| 1 | 呼出气体中部分可挥发性有机物用于诊断肺癌的预测模型显示文摘目的 :通过比较病理确诊的肺癌患者与健康人呼出气体中可挥发性有机物(volatile organic compounds,VOCs)的差异,寻找可作为肺癌诊断的特异性生物学标志物。方法:收集63例病理确诊的肺癌患者(研究组)和72例健康人(对照组)的呼出气体,应用电子鼻对呼出气体中的VOCs进行检测。采用MannWhitney U检验对2组的VOCs进行比较,二分类logistic回归及逐步法筛选变量,建立预测模型,并应用受试者工作特征(receiver operating characteristic,ROC)曲线评价预测模型的诊断能力。结果:研究组与对照组的二甲基甲烷、乙醇、甲烷、己烷、2,2,4,6,6-五甲基庚烷、篙属酮、侧柏醇、十二烷和1,2,6-三甲基萘这9种VOCs成分浓度的差异有统计学意义,结合临床其他相关信息建立的预测模型的方程式为P=1/[1+e(-9.006+0.101×X 1+0.01×X 2+0.02×X 3-0.518×X 4)](其中X 1、X 2、X 3和X 4分别为年龄、己烷浓度、2,2,4,6,6-五甲基庚烷浓度和1,2,6-三甲基萘浓度)。此预测模型对研究组和对照组的判对率分别为80.6%和83.9%,敏感度和特异度分别为74.0%和93.0%。结论:呼出气体中VOCs的组成和浓度可以反映机体的代谢状态和特定的疾病状态。建立和开发呼出气体中VOCs的数据库,对肺癌诊断具有重要的理论和实践意义。 | 陈璐 刘畅 康涛 Teong Lim 唐永明 徐萌 惠宏襄 | 2015 | 肿瘤2015，35，4： | 8 |
| 2 | Cultivation of microalgae for biodiesel production:A review on upstream and downstream processing显示文摘Fluctuating market price of fossil fuel and overwhelming emission of greenhouse gases to the atmosphere have resulted in climate change and have been a global concern in this decade. Hence, biodiesel has become an alternative option to fossil diesel as it is renewable and environmentally friendly. Nevertheless, this alternative fuel that is usually derived from terrestrial oil crops will cause shortage in food supply and deforestation if mass production is realized. In recent years, cultivation of aquatic microorganism(particularly microalgae) to produce biodiesel is considered as a practical solution due to their high growth rate and ability to synthesize large quantity of lipid within their cell. However, the development of energy and cost-efficiency of microalgae cultivation system are the main issues in producing renewable microalgae biodiesel. Of late, wastewater or organic compost has been used as the cultivation medium as it can provide sufficient nutrients to sustain microalgae growth.Microalgae cultivation method and system are vitally important as these factors undoubtedly affect the final microalgae biomass and lipid yield. In this review, the cultivation system of microalgae, nutrients demanded for microalgae production, cell harvesting and drying, microalgae oil extraction, and utilization of microalgae biomass for biodiesel production are introduced and discussed. It is anticipated to convey clearer perspectives in upstream and downstream processes in microalgae-derived biodiesel production. | Xin Bei Tan Man Kee Lam Yoshimitsu Uemura Jun Wei Lim Chung Yiin Wong Keat Teong Lee | 2018 | Chinese Journal of Chemical Engineering2018，26，1： | 6 |
