巨灾保险需求建模分析的初步探讨

本文以居民或家庭的房屋巨灾保险为例,从微观层面试图选取或借鉴相关模型分析房屋巨灾保险的需求。由于房屋所面临的风险还包括非巨灾风险,因此本文将巨灾风险与非巨灾风险统括到所设计或选取的模型中,对巨灾保险的需求作一初步探讨

Analysis on lung cancer mortality and years of life lost in urban and rural residents of Xiamen city

目的了解厦门市城乡居民肺癌死亡和减寿趋势变化,为厦门市肺癌预防控制工作提供依据。方法通过厦门市死因监测系统收集2003-2014年厦门市城乡居民肺癌死亡资料,采用SAS 9.1软件对死亡率、标化死亡率(SMR)、潜在寿命损失年(PYLL)、寿命损失率(PYLLR),标化寿命损失率(SPYLLR)、平均减寿年数(AYLL)、死亡率年均变化百分比等指标进行评价。结果 2003-2014年厦门市城市、农村居民肺癌死亡率分别为29.64/10万和25.40/10万,年均分别上升5.63%和4.98%;标化死亡率分别为32.78/10万和27.13/10万;无论城市、农村,肺癌标化死亡率男性均明显高于女性;死亡率均随着年龄的增长而升高,在70~79岁年龄组达到高峰。城市居民肺癌所致PYLL、PYLLR、SPYLLR、AYLL分别为27 944人年、2.11‰、2.41‰和7.12年,而农村分别为17 807人年、2.47‰、2.69‰和9.74年。结论厦门市城乡居民肺癌死亡呈上升趋势和老龄化趋势,应以男性、老年人群作为重点关注对象,重视肺癌防治工作。Objective To explore the trend of lung cancer mortality and years of life lost in urban and rural residents of Xiamen,and to provide the basis data for preventing lung cancer in Xiamen. Methods The lung cancer mortality data of urban and rural residents in Xiamen during 2003 to 2014 were collected. The SAS 9.1 software was used to assess the mortalities, the standard mortality rates(SMR), the potential years of life lost(PYLL), the rates of potential years of life lost(PYLLR), the standard rate of potential years of life lost(SPYLLR) the average potential life lost(AYLL) and the average percentage change(APC) of mortalities.Results During 2003 to 2014, the average lung cancer mortalities of urban and rural residents in Xiamen were 29.64/100 000 and25.40/100 000, respectively; the APCs were 5.63% and 4.98%, respectively; the SMRs were 32.78/100 000 and 27.13/100 000 persons, respectively; the lung cancer mortality in males was significantly higher than that in females, and the mortalities increased with age; the lung cancer mortality in 70-79 years old group was the highest. The PYLL, PYLLR, SPYLLR, and AYLL due to lung cancer in urban residents were 27 944 person years, 2.11‰, 2.41‰ and 7.12 years, respectively; and the PYLL, PYLLR, SPYLLR,and AYLL due to lung cancer in rural residents were 17 807 person years, 2.47‰, 2.69‰, and 9.74 years, respectively.Conclusion The lung cancer mortalities in urban and rural residents of Xiamen city had the increasing and aging trend. More attention should be paid to males and elders for preventing and treating of lung cancer.福建省卫生厅青年科研课题(2014-2-78

没食子酸衍生物对蘑菇酪氨酸酶的抑制机理

蘑菇褐变过程主要是由于其酪氨酸酶的催化作用引起的,寻找该酶抑制剂在食品保鲜和储藏中的应用具有重要的意义.作者在实验中,发现没食子酸十二烷基酯和没食子酸香叶酯对蘑菇酪氨酸酶有较强的抑制作用,测定它们抑制蘑菇酪氨酸酶二酚酶的酶活力下降50%的抑制剂浓度(IC50)分别为1.55和0.25 mmol/L.显示没食子酸香叶酯的抑制作用强度是没食子酸十二烷基酯的6倍.研究了这两种抑制剂对蘑菇酪氨酸酶的抑制作用动力学,结果表明:没食子酸十二烷基酯和没食子酸香叶酯对酶的抑制作用均表现为可逆反应,前者为反竞争性,其抑制常数KIS为0.636 mmol/L;而后者为混合型,抑制常数KI和KIS分别为0.133和0.453 mmol/L
