1饮水氟与人群龋齿关系的调查研究显示文摘为探讨不同饮水氟浓度、不同营养水平对人群龋齿的影响,分低水氟(<0.3mg/L),适宜水氟(1mg/L)和高水氟(>4.8mg/L)三个氟水平,每一氟水平又分正常低营养二组,共6个人群组,每组120人,平均年龄46岁,调查计算了人群日总摄氟量,检查了冠面龋与根面龋。同时每组调查了8~15岁学生100人。结果经统计分析表明,低饮水氟地区人群的龋患率与龋患指数均明显高于其他两组。低水氟与适宜水氟组人群均无氟斑牙发生,高饮水氟组发生了严重的氟中毒。此结果证明,适宜水氟(1mg/L)能起到预防氟中毒与预防龋齿的双重作用。不同营养水平方面,只在低饮水氟2组之间表现出来,低营养组的龋患率明显高于正常营养组。梁超轲 YLi 王景占 吴云鹏 YLi BPKatz EJBrizendine GKStookey 1998环境与健康杂志1998,15,2:5
2不同氟水平地区人群膳食营养调查显示文摘为了解膳食蛋白质和钙不足与地方性氟中毒流行和程度的关系,选择全国三组低、适宜和高饮水氟浓度地区,每组包括营养正常和不足两调查点,进行膳食营养和总摄氟量调查。调查结果表明营养正常地区膳食营养摄入量为蛋白质72.4~109.7g,优质蛋白占总蛋白比为28~29%,热量2649~3917Kal,钙734.1~1009.9mg,其他成份也基本达到供给量标准,总摄氟量1.7~14.8mg,营养不足地区蛋白质57.4~62.3g 优质蛋白占总蛋白1.8~7.4%,热量2097~2414Kal,钙373.8~450.8mg,维生素 A 和 B_2也明显不足,总摄氟量1.2~1 5.3mg。营养正常与不足地区氟斑牙患病率无显著性差异。但高水氟组营养不足地区氟骨症患病率显著高于营养正常地区,说明营养缺乏特别是蛋白质,热量和钙不足加重氟病的流行和程度。曹静祥 孙淑庄 YLi GKStookey 1997中国地方病学杂志1997,16,5:4
3燃煤污染型氟中毒对人群生化电解质水平的影响显示文摘目的 探讨燃煤污染型氟中毒人群与正常人群之间的生化电解质水平有无差异。方法 选择燃煤重度中毒病区 2个村 ,与无室内燃煤氟污染的 2个对照村。每个村检测农民 119~ 12 2人 ,即氟中毒 2 47人 ,无氟中毒农民 2 41人 ,男女各半 ,年龄 35~ 6 0岁。采样测定环境氟水平 ,计算每人每日总摄氟量 ,同时检查氟斑牙 ,右前臂拍 X片诊断氟骨症。应用自动生化分析仪分析血清中 16项生化电解质水平 ,即钾、钠、氯、钙、磷、葡萄糖、尿素氮、尿酸、肌酐、总蛋白、白蛋白、谷草转氨酶、肌酸肌酶、碱性磷酸酶、总胆红素和总胆固醇。以 ANOVA方法进行方差分析。结果 研究结果表明 ,2个氟中毒村每人日总摄氟量为 6 .5 7mg和 8.5 4m g,氟斑牙患病率为92 .86 %与 99.0 2 % ,氟骨症患病率为 14.81%和 14.13% ,2项指标均属正常范围 ,且无氟骨症发生。结论 燃煤污染氟中毒人群与正常人群生化电解质水平均属正常范围。血清碱性磷酸酶活性随氟中毒加重而升高 ,血钾水平随氟中毒加重而升高 。梁超轲 张淑兰 李文华 马凤 吴云鹏 YLi BPKatz EJBrizendine GKStorkey3.? 2000中国地方病学杂志2000,19,1:3
4Towards a global One Health index: a potential assessment tool for One Health performance显示文摘Background:A One Health approach has been increasingly mainstreamed by the international community, as it provides for holistic thinking in recognizing the close links and inter-dependence of the health of humans, animals and the environment. However, the dearth of real-world evidence has hampered application of a One Health approach in shaping policies and practice. This study proposes the development of a potential evaluation tool for One Health performance, in order to contribute to the scientific measurement of One Health approach and the identification of gaps where One Health capacity building is most urgently needed.Methods:We describe five steps towards a global One Health index (GOHI), including (i) framework formulation;(ii) indicator selection;(iii) database building;(iv) weight determination;and (v) GOHI scores calculation. A cell-like framework for GOHI is proposed, which comprises an external drivers index (EDI), an intrinsic drivers index (IDI) and a core drivers index (CDI). We construct the indicator scheme for GOHI based on this framework after multiple rounds of panel discussions with our expert advisory committee. A fuzzy analytical hierarchy process is adopted to determine the weights for each of the indicators.Results:The weighted indicator scheme of GOHI comprises three first-level indicators, 13 second-level indicators, and 57 third-level indicators. According to the pilot analysis based on the data from more than 200 countries/territories the GOHI scores overall are far from ideal (the highest score of 65.0 out of a maximum score of 100), and we found considerable variations among different countries/territories (31.8–65.0). The results from the pilot analysis are consistent with the results from a literature review, which suggests that a GOHI as a potential tool for the assessment of One Health performance might be feasible.Conclusions:GOHI—subject to rigorous validation—would represent the world’s first evaluation tool that constructs the conceptual framework from a holistic perspective of One Health. Future application of GOHI might promote a common understanding of a strong One Health approach and provide reference for promoting effective measures to strengthen One Health capacity building. With further adaptations under various scenarios, GOHI, along with its technical protocols and databases, will be updated regularly to address current technical limitations, and capture new knowledge.Xiao-Xi Zhang Jing-Shu Liu Le-Fei Han Shang Xia Shi-Zhu Li Odel YLi Kokouvi Kassegne Min Li Kun Yin Qin-Qin Hu Le-Shan Xiu Yong-Zhang Zhu Liang-Yu Huang Xiang-Cheng Wang Yi Zhang Han-Qing Zhao Jing-Xian Yin Tian-Ge Jiang Qin Li Si-Wei Fei Si-Yu Gu Fu-Min Chen Nan Zhou Zi-Le Cheng Yi Xie Hui-Min Li Jin Chen Zhao-Yu Guo Jia-Xin Feng Lin Ai Jing-Bo Xue Qian Ye Liz Grant Jun-Xia Song Geoff Simm Jürg Utzinger Xiao-Kui Guo Xiao-Nong Zhou 2022Infectious Diseases of Poverty2022,11,3:3
5(−)- and (+)-Securidanes A and B, Natural Triarylmethane Enantiomers: Structure and Bioinspired Total Synthesis显示文摘Two pairs of enantiomers,(−)and(+)-securidanes A(1 and 2)and B(3 and 4)featuring unprecedented triarylmethane(TAM)skeletons,were isolated from Securidaca inappendiculata.Teir structures were established by spectroscopic data,X-ray crystallography,and CD analysis.A plausible biosynthetic pathway for 1−4 based on the co-isolated precursors was proposed.Bioinspired total synthesis of 1−4was completed in high yield,which in turn corroborated the biosynthetic hypothesis.Compounds 1−4 showed good inhibition against protein tyrosine phosphatase 1B(PTP1B).Te molecular docking demonstrated that the strongest inhibitor 3(IC50=7.52�M)reaches deeper into the binding pocket and has an additional H-bond.B.Zhou D.X.Liu X.J.Yuan J.Y.Li Y.C.Xu J.Li YLi J.M.Yue 2018Research2018,,1:2
