目的分析天津市某电子有限公司以流动人口为主的一起聚集性结核病疫情,探讨企事业单位流动人口结核病的防治措施。方法收集2017年1月至2018年4月天津市某电子有限公司确诊的19例结核病患者的个案调查表,密切接触者筛查报告及现场流行病学调查报告,对本次结核病疫情流行特点进行分析和总结。结果19例临床确诊的结核病患者年龄为21~42岁,平均(29.68±7.29)岁;15例为外省来津务工人员,4例为天津户籍人员。8例分布在整机组装(LX)部门,7例分布在电子段组装(LVI)部门。疫情发生后,该公司与塘沽结核病防治所前后共组织了3次密切接触者筛查,共筛查LX和LVI部门和患者宿舍人员共计1796名,累计发现17例疑似患者,确诊10例(58.82%)。根据疫情的三间分布,认为此次疫情为典型的混合传播,即首次聚集没有及时处置,导致续发病例继续传播,引发二代病例。结论本次疫情以流动人口为主,呈现出一定的聚集性。强化各级各类医疗机构责任意识,加强结核病核心知识宣传教育,健全结核病防治机构与辖区内大型用工企业传染病疫情沟通制度,是控制企事业单位流动人口结核病疫情的关键。

Suaeda salsa L. is a halophytic species that is well adapted to high salinity. In order to understand its salt tolerance mechanism, we examined the growth and vacuolar H^＋-ATPase （V-ATPase） response to NaCI within the shoots and roots. The growth of shoots, but not roots, was dramatically stimulated by NaCI. CI^- and Na^＋ were mainly accumulated in shoots. V-ATPase activity was significantly increased by NaCI in roots and especially in shoots. Interestingly, antisera ATP95 and ATP88b detected three V1 subunits （66, 55 and 36 KDa） of V-ATPase only in shoots, while an 18 kDa V0 subunit of V-ATPase was detected by both antisera in shoots and roots. It suggested that the tissue-specific characteristics of V-ATPase were related to the different patterns of growth and ion accumulation in shoots and roots of S. salsa.

Recently, algae biocrude has drawn considerable attention as algae are considered to be one of the major fuel feedstocks of the future. Based on some impressive results achieved under appropriate conditions, the algae hydrothermal liquefaction (HTL) process has proven to be energy efficient. However, the HTL of biocrude is characterized by a high nitrogen content, which prevents its use in the field of transportation due to the associated nitrogen oxide emissions. Despite this toxicity, few research efforts have focused on the denitrogenation of algae biocrude. In this study, we review the effect of different strain-specific operation parameters and process upgrades with respect to the nitrogen content of biocrude. To achieve denitrogenation, chemical engineering may be required, although some improvements in biocrude properties have been achieved in a number of process upgrades. The use of similar successful pathways has the potential to improve the field of HTL biocrude denitrogenation. These methods, including the adsorptive and extractive denitrogenations of fossil fuels and the hydrodenitrogenation of the main nitrogen compounds, are helpful for developing a better understanding of the potential of denitrogenation for algae HTL biocrude. We also recommend the use of some available catalysts and corresponding operation parameters to promote continued research on denitrogenation. © 2017, The Author(s).
