Investigation on the iodine status among the population in rural and urban areas of Xiamen in 2013

目的了解碘盐新标准实施后农村和城市人群的碘营养现况,为有效落实科学补碘防控策略提供依据。方法在农村和城市调查点各抽取1个镇的1个村,在每个村采集自来水厂出厂水和末梢水各2份;抽取30户以上居民,采集各户家庭食用盐,用3日称量法测算各户居民人均食盐摄入量;抽取18-45岁成人50名以上,采集尿样。在抽中的镇随机选择8-10岁儿童(男女各半)、孕妇和哺乳期妇女各50名以上,采集尿样。测定盐碘、尿碘和水碘含量。结果农村和城市自来水末梢水水碘含量均值分别为4.5μg/L和6.0μg/L;居民人均每日食用盐摄入量中位数分别为7.0和5.6g;8~10岁儿童尿碘中位数分别为152.0和181.2μg/L;哺乳妇尿碘中位数分别为108.3和107.7μg/L;18-45岁成人尿碘中位数分别为121.1和147.4μg/L;孕妇尿碘中位数分别为116.0和112.2μg/L,尿碘含量低于150μg/L的比例分别达67.9%和64%;除农村人均每日食用盐摄入量高于城市,农村18-45岁成人尿碘水平低于城市外,其他指标农村和城市间差异无显著性。结论厦门市仍是缺碘地区,在现有碘盐标准下,8-10岁儿童、18-45岁成人、哺乳期妇女的碘营养处于适宜水平,但孕妇的碘营养不足,要开展针对孕期人群的碘营养监测和指导,杜绝碘缺乏所造成的危害。Objective To gain knowledge of the iodine status among the population in rural and urban areas after the implement of new standard for edible salt and to provide scientific evidence for the initiative of the iodine supplement strategy. Method 1 village / community was selected randomly from rural and urban area as research site respectively. 2 samples of treated water and tap water were collected respectively in both sites, 30 + houses were enrolled randomly and edible salt samples were collected. 3days weighed record was employed to estimate average salt daily intake. Urine sample was collected from 50 + adults aged from 18 to 45. Identical sample was also collected from 50 + children aged from 8 to 10( same amount of subjects in both genders),pregnant women, and lactating women respectively. Iodine level of water, salt, and urine was determined by laboratory assay.Results The iodine concentration of tap water in rural and urban areas was 4. 5 μg / L and 6. 0 μg / L,respectively. The median of average iodine intake in rural and urban areas was 7. 0 g and 5. 6 g, respectively. The median in urine iodine was 152. 0 μg / L and 181. 2 μg / L,respectively. This measurement in lactating women was 108. 3 μg / L and 107. 7 μg / L,respectively. And it was121. 1 μg / L and 147. 4 μg / L in adults aged 18 to 45, respectively. As for the pregnant women, the iodine level reached 116. 0μg /L and 112. 2 μg /L,respectively. The proportion of subjects has urine iodine level less than 150 μg /L reached 67. 9 % and 64 %, respectively. The average salt intake in rural area was higher than urban significantly, and the urine iodine level in adults aged 18 to 45 from rural area was significantly lower than urban. No significance was found in other comparison. Conclusion Through our investigation,Xiamen is still an iodine deficiency area. Under the implement of new edible salt standard, the iodine status in children aged 8 to 10, adults aged 18 to 45 and lactating women was adequate, however, we found that pregnant women enrolled in our study have iodine deficiency in some degrees. Therefore the iodine surveillance and dietary guidance should be performed among pregnant women to eliminate the harm caused by iodine deficiency

抗人肺癌单克隆抗体(3D3)的研制及其特性鉴定

本文用人肺腺癌组织免疫的BALB/c小鼠脾细胞与小鼠骨髓瘤Sp2/0细胞融合,获得1株单克隆抗体(McAb 3D3)。Ig类测定为IgG_1型。杂交瘤培养上清液和腹水的效价分别为1∶10~3～10~4和1∶10~6。采用间接免疫荧光法(IFA)观察到McAb3D3主要与肺腺癌细胞株A549和L342反应,与其它组织肿瘤细胞株没有反应。ABC免疫酶染色试验显示McAb3D3主要与肺腺癌组织反应,与正常肺组织没有反应

氮、硅限制对赤潮藻扁面角毛藻休眠孢子形成的影响

休眠孢子的形成对于赤潮藻种群的保存、延续以及分布扩散等均具有重要的意义。通过单因子营养限制研究氮、硅对赤潮藻扁面角毛藻(Chaetoceros compressus)休眠孢子形成的影响,结果表明:培养基中氮的初始浓度对休眠孢子的出现时间有一定影响。氮的初始浓度越低,休眠孢子出现的时间越早;反之,氮的初始浓度越高,休眠孢子出现的时间越晚。氮缺乏是硅藻形成休眠孢子的必需条件之一,当培养基中氮含量低于10μmol.L-1时,扁面角毛藻可以形成休眠孢子。氮缺乏诱发的休眠孢子的形成需要大量的硅,当培养基中硅含量低于23μmol.L-1时,即使氮缺乏,扁面角毛藻也几乎不再继续形成休眠孢子。这说明硅藻休眠孢子的形成不仅受氮浓度的影响,还与硅浓度有关

A study on bioremediation of eutrophication of mariculture waters by Gracilaria lemaneaformis

于2002年至2004年期间,在福建省东山岛的八尺门鱼类网箱养殖区、西埔湾对虾养殖区、乌礁湾鲍鱼养殖区等进行了龙须菜(G racilaria lem aneaf orm is)对动物海水养殖造成的富营养化的生物修复研究。结果表明,从围隔实验到小面积的海区实验到大面积的海区推广试点,龙须菜对富营养化的海水均有良好的修复效果。围隔实验中,龙须菜能使网箱养殖区缺氧的海水达到过饱和状态,对无机氮(IN)、无机磷(IP)的去除率达80%以上;实验海区,修复区的溶解氧(DO)浓度明显高于非修复区,IN、IP、叶绿素(Ch l-a)浓度低于非修复区;推广海区,鲍鱼养殖污水流经龙须菜养殖区后,IN、IP得到有效的吸收,DO浓度得到提高。因此,大面积养殖龙须菜对减轻养殖污水对海区的污染,防止水体富营养化,抑制赤潮的发生有积极作用。Eutrophication caused by mariculture has become a serious environmental problem in Chinese coastal waters.Since macroalgae can absorb nutrients and increase the concentration of dissolved oxygen(DO),and can be ultimately removed from water by being harvested,macroalga-based bioremediation of eutrophication would be the best way to solve such environmental problems.The effects of Gracilaria lemaneaformis remediated eutrophication were studied.G.lemaneaformis,red seaweed,originated in Shandong Province,was cultivated on ropes in three typical mariculture areas at Dongshan island,Fujian province where mariculture is advanced.The mesocosm experiment was conducted in Bachimen fish-cage area;the bioremediation experiment——in a field about 3 hm~2 in Xipu bay where the shrimp-farm and urban sewage is discharged;and in the spread application experiment,about 400 hm~2 were tested in Wujiao bay where abalone sewage is discharged.Water quality parameters were monitored during all the experimental stages.According to different tide and depth of the sea,two floating-rafts,i.e.bamboo raft and string raft,were devised to cultivate G.lemaneaformis on ropes in sea.The results demonstrated that the effects of bioremediation of eutrophication of mariculture waters by G.lemaneaformis were obvious regardless to the place of experiment: in mesocosm one,in a small-scale's bioremediation or in large area's spread application.The results of mesocosm experiments showed that G.lemaneaformis increased DO from low concentration to supersaturation and increased DO saturation from about 60% to 200%;in meantime,it absorbed the inorganic nitrogen(IN) and inorganic phosphorus(IP) above 80% during 3～4 days.In bioremediation area in Xipu bay,the specific growth rate of G.lemaneaformis was 9% during the first month and 6% during the next half month.The DO concentration in bioremediation area was significantly higher than that in non-bioremediation area: the highest DO concentration in bioremediation area was 5.6 mg·L~(-1) higher than that in non-bioremediation area in the same monitoring transect,the highest DO saturation was 198.7%.Furthermore,it increased the DO concentration of downstream seawater.And the IN and IP concentrations in bioremediation area were lower than those in non-bioremediation area.Besides,the microaglae were restrained,the concentration of Chlorophyll-a in bioremediation area was lower than that in non-bioremediation area,whereas,the transparence was contrary.In spread application area,when the abalone cultural sewage went through G.lemaneaformis cultural areas,the nitrogen and phosphorus were effectively absorbed.Especially,the IP concentration of abalone cultural sewage discharging area was above 0.05mg·L~(-1),however,that in G.lemaneaformis cultural areas was below 0.015mg·L~(-1).The DO concentration was increased in G.lemaneaformis cultural areas,its saturation was above 120%,the highest one was 166%,but,in non-cultural areas,the DO saturation was about 100% normally.In conclusion,by large farming of G.lemaneaformis in animal maricultural areas,it is possible to alleviate the pollution of marine environment,prevent from eutrophication and control the red tide.At the same time,because G.lemaneaformis was the ideal food for abalone and material to produce agar,it could resolve the problems of the local abalone culture.Hence,large farming of G.lemaneaformis in the eutrophic mariculture areas could reduce environmental impact and increase economic output,and good environmental and economic advantages would be obtained.福建省重大科技资助项目(2002Y005)~
