“和”——中医学的重要特色

"和"表达了一种"和谐平衡"的哲学理念,是中医学的重要特色。中医生理、病理、辨证、养生、治疗等各个方面,处处体现出"和"的思维理念。从"和而不同"、"天人合一"、致"中和"3个方面分析"和"的古代哲学内涵并深入分析其在中医学领域的指导和实用价值。从气机升降出入讲究平衡、阴阳交通以和为美、五行生克制化协调平衡、经脉气血以通为和等方面总结中医基础理论,可发现处处贯穿着"中和观",并探讨中医临床诊治注重致"中和"。提出在中医学中,"中和观"强调本体论上的"和而不同",认识论上的"天人合一",方法论上的致"中和"。总结出"不和则病,不和则治,治则和,和则生,和则寿"的中医特色思维

X射线双星系统的探测

搜寻X射线双星并建立大规模样本是解决众多科学问题(如\"银河系中有多少黑洞X射线双星?黑洞和中子星之间有无质量间隙?球状星团中有无黑洞?\"等)的基础.爱因斯坦探针卫星拥有更灵敏的探测能力,将在运行的几年之中,预计可以发现一批新的中子星和黑洞X射线双星,研究其空间和动力学质量分布成为解决上述问题的关键.国家重点研发计划(编号:2016YFA040080X);;国家自然科学基金(编号:1133305);;中国科学院战略性先导科技专项(编号:XDA15052100,XDB23040000)资助项

Uptake and Metabolism Kinetics of TBT in Whelk(Thais clavigera)Exposed to Dietary

将牡蛎消化腺分别暴露在1000ng.l-1和100ng.l-1TbT水溶液中4周,然后将染毒的牡蛎消化腺分别投喂疣荔枝螺(THAIS ClAVIgErA)。经过45d的暴露和30d的净化,我们发现雌雄疣荔枝螺的消化和生殖系统能较快地吸收TbT(吸收速率ku=0.004-0.022.d-1),并且其代谢(生物代谢系数bdI=5.59-23.30)和排出速率(净化速率kE=0.024-0.053.d-1)也相对较快,各器官中TbT的代谢产物MbT占了相对较高的比例,因此TbT在食物链传递过程中没有出现生物放大的现象。此外,TbT有逐渐从雌螺消化系统向生殖系统转移的趋势,并且雌螺生殖系统对TbT的吸收和富集能力(ku=0.006-0.022.d-1,生物放大系数bMf=0.181-0.664)要显著强于雄螺(ku=0.004-0.014.d-1,生物放大系数bMf=0.142-0.376),但其代谢和净化速率(bdI=5.59-10.50,kE=0.024-0.025.d-1)却显著低于雄螺(bdI=11.5-12.4,kE=0.031-0.050.d-1),雌螺的生殖系统被认为是TbT转移和富集的潜在靶器官,这对我们今后开展TbT污染的环境监测和评价具有重要的参考价值。Oysters were respectively exposed to 1000 ng·L-1 and 100 ng·L-1 tributyltin(TBT) aqueous for 4 weeks,which was as dietary to feed the female and male Thais clavigera whelks for 45 days.Then these Thais clavigera were depurated for 30 days.The results show that TBT rapidly accumulated in their digestive and reproductive organs(ku=0.004-0.022 d-1).Moreover,elimination and biotransformation of TBT were also rapid(BDI=5.6-23.30,ke=0.024-0.053 d-1).MBT was the dominant metabolite in each tissue.Therefore,bio-magnification of TBT did not occur during the trophic transfer process.Additionally,to females,the mobilization of TBT from digestive to reproductive organs and bioaccumulation of TBT(ku=0.006-0.022 d-1,BMF=0.181-0.664) were more obvious than that of the males.However,lower metabolism and elimination of TBT(BDI=5.6-10.5,ke=0.024-0.025 d-1) in female reproductive organs,which indicated that the reproductive organs of females were the main targets of TBT accumulation.The results are important to the risk assessment of TBT contamination in coastal environments.国家“863”项目No.2007AA09Z126;国家自然科学基金项目No.40476048;20777060;海洋公益性行业科研专项经费;No.20080509

Analysis of genetic effects for grain quality characters in late indica hybrid rice

以6个籼型野败三系不育系为母本,5个晚籼恢复系为父本,进行不完全双列杂交设计,对籼型杂交晚稻稻米品质性状的遗传效应进行分析.结果表明:糙米率、精米率、垩白粒率、碱消值和胶稠度等5个性状同时受到种子遗传效应和细胞质遗传效应的控制,但细胞质遗传效应都大于种子遗传效应.整精米率、垩白度和透明度等3个性状只受到种子遗传效应的控制,并且都以种子显性遗传效应为主.直链淀粉含量同时受到种子遗传效应和母体植株遗传效应的控制,但以种子显性遗传效应为主.粒长和长宽比同时受到母体植株加性遗传效应和母体植株显性遗传效应的控制.不育系451A、全丰A、长丰A及恢复系蜀恢527、科恢752、岳恢94是配制优质杂交晚稻组合的优异亲本.Six CMS(Fuyi A etc.) and 5 late-restorers(Minghui 63 etc.) were used in partial diallel crosses to analyse the genetic effects of grain quality characters in late indica hybrid rice,using seed quantitative traits genetic models and analysis methods developed by Zhu Jun in cereal crops.The results showed that the 5 characters were simultaneously controlled by seed genetic effects and cytoplasmic genetic effects in percentage of brown rice,percentage of milled rice,percentage of chalky grain,gelatinization temperature and gel consistency,but the cytoplasmic genetic effects were all higher than the seed genetic effects.The 3 traits were only controlled by seed genetic effects in percentage of head rice,chalkiness and translucency,and the effects were all mainly come from seed dominance genetic effects.Amylose content was controlled by seed genetic effects and maternal genetic effects,but was mainly controlled by seed dominance genetic effects.The 2 traits were simultaneously controlled by maternal additive genetic effects and maternal dominance genetic effects in kernel length and length/breadth ratio.The 6 materials were available parents for breeding late indica hybrid rice combinations with good quality,which included the CMS of 451 A,Quanfeng A and Changfeng A,the restorers of Shuhui 527,Kehui 752 and Yuehui 94.福建省自然科学基金资助项目(B0310020

中国海及邻近区域碳库与通量综合分析

中国海总面积约470万平方公里,纵跨热带、亚热带、温带、北温带等多个气候带.其中,南海北依\"世界第三极\"青藏高原、南邻\"全球气候引擎\"西太平洋暖池,东海拥有全球最宽的陆架之一,跨陆架物质运输显著,黄海是冷暖流交汇区域,渤海则是受人类活动高度影响的内湾浅海.中国海内有长江、黄河、珠江等大河输入,外邻全球两大西边界流之一的黑潮.这些鲜明的特色赋予了中国海碳储库和通量研究的典型代表意义.文章从不同海区（渤海、黄海、东海、南海）、不同界面（陆-海、海-气、水柱-沉积物、边缘海-大洋等）,以及不同生态系统（红树林、盐沼湿地、海草床、海藻养殖、珊瑚礁、水柱生态系统等）多层面对海洋碳库与通量进行了较系统地综合分析,初步估算了各个碳库的储量与不同碳库间的通量.就海气通量而言,渤海向大气中释放CO2约0.22Tg Ca-1,黄海吸收CO2约1.15Tg Ca-1,东海吸收CO2约6.92～23.30Tg Ca-1,南海释放CO2约13.86～33.60Tg Ca-1.如果仅考虑海-气界面的CO2交换,中国海总体上是大气CO2的\"源\",净释放量约6.01～9.33Tg Ca-1.这主要是由于河流输入以及邻近大洋输入所致.河流输入渤黄海、东海、南海的溶解无机碳（DIC）分别为5.04、14.60和40.14Tg Ca-1,而邻近大洋输入DIC更是高达144.81Tg Ca-1,远超中国海向大气释放的碳量.渤海、黄海、东海、南海的沉积有机碳通量分别为2.00、3.60、7.40、7.49Tg Ca-1.东海和南海向邻近大洋输送有机碳通量分别为15.25～36.70和43.39Tg Ca-1.就生态系统而言,中国沿海红树林、盐沼湿地、海草床有机碳埋藏通量为0.36Tg Ca-1,海草床溶解有机碳（DOC）输出通量为0.59Tg Ca-1;中国近海海藻养殖移出碳通量0.68Tg Ca-1,沉积和DOC释放通量分别为0.14和0.82Tg Ca-1.总计,中国海有机碳年输出通量为81.72～103.17Tg Ca-1.中国海的有机碳输出以DOC形式为主,东海向邻近大洋输出的DOC通量约15.00～35.00Tg Ca-1,南海输出约31.39Tg Ca-1.综上,尽管从海-气通量看中国海是大气CO2的\"源\",但考虑了河流、大洋输入、沉积输出以及微型生物碳泵（DOC转化输出）作用后,中国海是重要的储碳区.需要指出的是,文章数据是基于中国海各海区碳循环研究报道,鉴于不同研究方法上的差异,所得数据难免有一定的误差范围,亟待将来统一方法标准下的更多深入研究和分析.国家重点研发计划项目(编号:2016YFA0601400);;国家自然科学基金项目(批准号:91751207、91428308、41722603、41606153、41422603);;中央高校基础研究项目(编号:20720170107);;中海油项目(编号:CNOOC-KJ125FZDXM00TJ001-2014、CNOOCKJ125FZDXM00ZJ001-2014)资
