The global warming is the most serious environmental problems that we are now facing ***'s because of the rising of the CO in the *** the one hand,the rising of the CO in the atmosphere is because of using of fossil fuel,the other hand is because the changes of land utility *** changes of land utility ways have important effect on the budget of the biggest land carbon cool—soil carbon *** June to November in 2.06,the soil respiration dynamics of chinese fir plantation and Phyllostachys pubescens was measured in middle subtropical zone of *** object of this study was to discover the effects of changes of land utility ways on the land carbon output,by studying the soil respiration of chinese fir plantation and Phyllostachys *** results show that:①:The soil respiration dynamics in the chinese fir plantation and Phyllostachys pubescens was is approximately the *** mean value of chinese fir plantation and Phyllostachys pubescens was 5.76μmol·m-2.s·1 and 2.47μmol·m-2.s-1 respectively.②It was known from the comparison of the soil respiration diurnal changes in the two forest land that although the soil respiration varied per day,the variation is very,little. We get the same rule from the comparison of soil respiration diurnal changes in chinese fir plantation and Phyllostachys pubescens in four months（7,8,9,10）.It is feasible to submit the mean respiration value of the whole day by the measures at 9:00 AM,Because of the little soil temperature changcs.③The exponential equation between soil respiration and 5 cm soil temperature of chinese fir plantation and Phyllostachys pubescens was y=0.94e0.066x and y=0.83e0.081x.④ The primary result was that CO released from the litters contribute 33% to the soil *** addition,the rain has remarkable activity to the soil respiration.

chinese Science Bulletin 1999年第6期44卷 541-544页

The role of CDK4 in human breast cancer cell proliferation and expression of cyclinD1, cyclinE and CDK2.has been investigated using inhibition of CDK4 expression by antisense RNA. When CDK4 expression was inhibited, the rate of cell proliferation and tumorigenecity decreased *** indicates that CDK4 plays an important role in formation and development of breast tumor. The resuits of Northern blot analysis showed that the levels of cyclinD1 and CDK2.mRNAs changed slightly whereas the level of cyclinE mRNA decreased obviously. It is suggested that the expression of CDK4 is necessary for induction of cyclinE expression. Thus, inhibition of CDK4 expression affects not only the role of CDK4 itself but also the role of other genes.

"5.12.汶川地震不仅直接造成了巨大的人员和财产损失,同时还诱发了大量的崩塌、滑坡、泥石流等次生山地灾害。崩塌、滑坡直接为泥石流活动提供了丰富的松散固体物质,再加上在地震荷载的多次往复作用下,山体的整体性遭到破坏,大量坡体失稳,岩体破坏,使这些泥石流沟在今后较长一段时间内处于活跃期。2.08年6月18日,位于重震区的茂县东兴乡竹包头沟暴发泥石流,将主河湔江堵断随后溃决,对临近的"302.省道造成了较为严重的危害。该沟上游段沟床比降大,岸坡较陡,流域内出露的岩石以千枚岩为主,易风化破碎,在地震中形成许多崩塌和滑坡,加之流域降水集且多局地性暴雨,有利于泥石流的发育。在调查访问的基础上,估算该次泥石流的容重为2.0 g/cm3,为高容重粘性泥石流。计算出其流速在10 m/s以上,流量约300 m3/s,总规模为1×105m3。竹包头沟泥石流固体物质的主要来源为地震引发的崩塌和滑坡堆积物,根据遥感资料测算,总方量达3×1010m3以上,再次暴发泥石流的可能性很大。为减弱泥石流活动,减轻泥石流造成的损失,提出以下应对措施:以生物防治措施为主,减少泥石流物源;加强监测,及时警报,减轻泥石流危害;普及泥石流知识,提高防灾减灾能力。

目的:一些具有确切生物活性的植物产品,由于材料基源的差异被划分为不同的等级。本试验以黄连为例,期望建立一种能更好的综合评价不同植物品种质量的方法。方法 :本试验采用HPLC结合微量量热法来建立三种不同基源的黄连（味连、雅连、云连）的色谱指纹图谱（CF）及生物指纹谱（BF）。从不同浓度的黄连对痢疾杆菌生长P-t曲线的影响得到相关生物学定量参数,并利用典型相关分析法（CCA）分析CF与BF之间的"谱效关系"。结果 :结果显示,"谱效关系"密切相关。在黄连药材中,药根碱,黄连碱,巴马汀和小檗碱是主要的抗菌成分。结论 :虽然黄连只是一个代表性的植物产品,但是上述方法也为其他品种植物药的质量评价提供了模范。所以,所以运用化学分析与生物分析相结合的方法来评估具有生物活性的植物产品的质量可行的。
