Survey on the distribution of dietary glycemic load and dietary insulin load of urban residents in Xiamen

目的了解厦门市城区居民碳水化合物消费情况及膳食血糖负荷及膳食胰岛素负荷的现状,调查膳食血糖负荷及膳食胰岛素负荷与生化指标。方法根据全国营养调查方案,2010年10-12月对厦门市城区的6个社区居委会成年居民进行调查,采用连续3 d 24 h回顾法对其中的291人进行膳食调查、身体测量及生化指标测量;根据膳食血糖生成指数(GI)和碳水化合物摄入量计算膳食血糖负荷(GL);根据膳食胰岛素指数(II)和能量及食用频率计算膳食胰岛素负荷(IL)。结果被调查的厦门市城区成年居民的平均膳食血糖指数为75.2;平均膳食血糖负荷为179.1;平均膳食胰岛素指数为30.4,平均膳食胰岛素负荷为247.2。粮谷类对膳食GL、IL的贡献达92.0%、83.1%。不同GL、IL水平的被调查人群的身体测量及生化指标间的差异无统计学意义;通过多元线性回归分析并未发现膳食GI、GL、II、IL与糖尿病的患病风险有明显的相关性。结论粮谷类食物是厦门市城区居民膳食GL、IL的主要来源,低膳食GL的人群粮谷类消费低,脂肪消费高,膳食结构不合理;并未发现膳食GL、IL与身体测量及生化指标之间的联系。Objective This work was to investigate the consumption of carbohydrate and distribution of dietary glycemic load(GL)and insulin load(IL) of urban residents in Xiamen. Methods According to the National Nutrition Survey program, six communities' residents of Xiamen were selected for the survey from Oct.~ Dec., 2010. A total of 219 subjects were surveyed with the 3consecutive days and 24 hours review method to acquire the food consumption data and underwent health examination. Dietary insulin load was calculated as a function of the food insulin index, and the energy content of individual foods was reported on food-frequency questionnaires. Dietary glycemic load was calculated by GI. Results 92.1% of the dietary glycemic load and 83.1%of the dietary insulin load were from cereals. Dietary insulin load and dietary insulin index were not associated with the overall biochemical index. The dietary GI, GL, II, IL was not positively associated with the risk of diabetes. Conclusion People with low GL tend to consume more fat and less carbohydrates

Estimation of the sources of organophosphorus pesticides in Xiamen sea area,

利用SPEGCFPD对厦门附近海域的微表层、表层、底层海水及九龙江入海口高、低潮水中有机磷农药进行了分析.结果表明,有机磷农药的含量范围为:低于检测限～725.54ng·L-1,平均值为136.47ng·L-1.研究海区中马銮内湾有机磷农药污染最为严重(165.77～453.42ng·L-1,平均296.01ng·L-1),九龙江口、西海域和西南海域污染水平接近(16.26～200.65ng·L-1,平均84.59ng·L-1),东部海域有机磷农药污染最轻(10.38～66.01ng·L-1,平均38.14ng·L-1).九龙江入海口高潮水中农药的浓度明显低于低潮水中浓度,说明海域中多数农药污染来源于九龙江流域输入,少数农药来源于海域周边地区或九龙江流域和海域周边地区共同输入,微表层对有机磷农药的富集作用不明显. 【英文摘要】 Organophosphorus Pesticides (OPPs) were determined in microsurface water, subsurface water and bottom water in Xiamen sea area with SPE-GC-FPD. The result showed that the levels of all OPPs ranged from below detection limit to 725.54ng·L -1, the mean was 136.47ng·L -1. The pollution in Maluan Bay was the most serious(165.77～453.42ng·L -1,mean 296.01ng·L -1) and the Eastern Sea was the slightest(10.38～66.01ng·L -1,mean 38.14ng·L -1).

阿托伐他汀对心室重塑和心肌 AVP、TGF-β1的影响

【目的】探讨阿托伐他汀能否通过抑制AVP的分泌而延缓心肌纤维化，为改善心肌梗死后心室重塑提供新思路。【方法】通过结扎大鼠冠状动脉前降支建立大鼠心肌梗死模型。建模成功后将大鼠分为假手术组（sham组）、心肌梗死大鼠安慰剂治疗组（MI组）及心肌梗死大鼠阿托伐他汀治疗组（A组），每组各有10只大鼠。干预5周后，超声心动图检测大鼠心功能；处死大鼠后，收集心肌组织标本，计算左心室质量指数；ELISA法检测左心室非梗死区和血清的血管加压素（AVP）含量；Masson染色检测心肌间质纤维化水平；免疫组织化学染色检测左心室非梗死区Ⅰ型胶原的表达；Western blot测定左心室非梗死区转化生长因子-β1（TGF-β1）蛋白的表达。【结果】干预5周后，Sham组、MI组和A组分别存活10只、9只和10只大鼠。与Sham组大鼠比较，MI组和A组大鼠的左室质量（LVM）和左室质量指数（LVMI）增加、左室射血分数（LVEF）降低、心肌间质纤维化明显加重、左心室非梗死区Ⅰ型胶原蛋白的表达、AVP含量以及TGF-β1蛋白表达水平明显升高（P<0.05）；阿托伐他汀干预后，LVM和LVMI降低、LVEF升高、心肌间质纤维化减轻、左心室非梗死区Ⅰ型胶原蛋白的表达、AVP的含量以及TGF-β1的蛋白表达水平显著降低（P<0.05）。【结论】阿托伐他汀能够改善心肌梗死后心室重塑，可能与抑制心室AVP的分泌及下调TGF-β1的表达有关
