"It is possible that for some patients topical fluorouracil may have an important role against photo-aging," they wrote. For others, however, it may not be cosmetically acceptable given that a standard course of therapy may last two to three weeks and the ensuring reaction can persist for several more weeks.

他们写道，对有些患者而言，局部氟尿嘧啶治疗对预防光老化很可能起着重要作用；而对为追求美容的其他患者，这是不可取的，因为一次标准的治疗过程要持续2-3周，药物反应可能会持续更长时间。

What\'s more, different intervals of UV have their own characters in influencing DNA: the damage to some bases by UVA may be more serious than that by UVB, and UVB did more severe damage to some deoxyribose than UVA; however, as far as the pyrimidine bases are concerned, the damage by UVB is by far more serious than that by UVA. These results may indicate that there are preferential damaging sites on DNA molecules caused by UVA and UVB irradiation. Moreover, with UVA or UVB irradiation for a long time, the photoreactivation of DNA occurred. The serious damage to deoxyribose and bases by UVB and UVC may confirm the conformation of cyclobutane pyrimidine dimers and (6-4) photoproducts.

而不同波段紫外辐射对DNA的损伤各具特点并且差异明显，UVA对一些碱基的损伤比UVB要严重，而UVB在对脱氧核糖和磷酸盐的损伤上又比UVA要严厉，但就嘧啶碱基来说，UVB对它的损伤远大于UVA，这似乎表明了不同的紫外波段对生物大分子DNA的损伤是有选择性的。

AMELX, AMBN and ENAM are the major matrix proteins of enamel, and play different roles during different developing stages of tooth germs. AMELX may facilitate the growth of crystals in the early mineral stage, and act in the repairing of bone. AMBN may promote the mineralization of enamel matrix, and also keep the shape and size of crystals. ENAM may act in remineralization and promoting the growth of crystals.

As an immunomodulator NO may play a role like a double-edged sword since it expresses both in immuonchalleged and immunosspresed states. 2. After received external stimulus the morphology of ependyma of SFO could be changed and varied with time course, particularly its cellular apoptosis do occur and earlier than the ordinary areas of the brain. 3. Astrocytes in SFO could express cFos protein induced by LPS, suggesting the cells may maintain homeostasis in the brain in a longer period and modulate immune state of the brain. 4. As a CVO, SFO may sense changes of blood-bearing immunosignals earlier and instantly response to them, thus as one of windows of the brain SFO do take part in immunomodulation within the brain.

通过我们的实验结果我们可以得出这样一些初步的结论：1、一氧化氮作为免疫调质参与了机体免疫，它既能在免疫激发状态下又可在免疫抑制状态下进行表达提示，NO在脑内免疫调节中的作用可能是双向的。2、穹窿下器的室管膜形态在接受外界刺激后，随着时间的变化而不同，扫描电镜下的凋亡形态虽需进一步证实，但室管膜细胞确实发生了凋亡，并且穹窿下器发生的较早。3、穹窿下器内的星形胶质细胞在给予大肠杆菌后确实可以表达c-fos蛋白，并可能通过自身的激活来较长时间的维持体液的动态平衡，调节脑内免疫状态。4、穹窿下器作为感受性室周器官之一，能够较早的感受血携免疫信息的改变并及时作出反应，可能作为外周免疫信息进入脑内的窗口之一来参与脑的免疫调节。

Root-derived organic carbon is composed of three compartments: root detritus, root eaudates and root symbionts, which represents a large important and potential C sink in forest ecosystems, The known responses of root derived organic carbon and heterotrophic microbes to elevated CO2 were reviewed. Overall, increases in root biomass, productivity, and exudation indicate an augmentation of C inputs into the soil via roots, although changes in root lifespan are still unclear and may modify this flux positively or negatively, Altogether, changes in root chemistry and morphology that may augment soil C storage under elevated CO2 include decreased N concentration and wider root diameter, Alternately, a shift in rooting depth upwards in the soil profile may increase average turnover rates of root detritus. Effects of CO2 concentration on C qualities of root exudates and root symbionts are the least understood components discussed here, Changes of soil heterotropic microbial activity and community under elevated CO2 still remained large uncertainties.

林木根源有机C包括根东通过根枯落物、根系分泌物和根共生菌周转3条途径向土壤输入的有机C，它是森林生态系统中一个重要的、潜在的C汇，综述了根源有机C与其微生物对CO2浓度升高的响应，虽然对根系寿命的变化尚不清楚，但CO2浓度升高将导致根系生物量、生产量、死亡量和分泌物的增加；同时，CO2升高亦促使根共生菌生物量的增加而增加了共生菌的C归还潜力，表明CO2升高使根源有机C的输入增加了，CO2农度升高情况下，根系化学性质和形态特征的这些变化均有利于增加土壤C的吸存；而根分布深度的降低则对土壤C吸存不利；CO2浓度升高对根分泌物和根共生菌质量的影响研究则极少，CO2浓度升高下土壤微生物活性和群落组成的变化存在较大的不确定性，目前CO2浓度升高下林木根源有机C对森林长期C吸存的贡献仍很不清楚。
