The results showed that the addition leading to -2-phenyl-2-(2-vinylpiperidin-1-yl) ethanol 7 could proceed with good diastereoselectivity and excellent yield (95%).(3) The selective N-deprotection of -2-phenyl-2-(2-vinylpiperidin-1-yl) ethanol 2 without affecting the vinyl group in the substrate were untaken.(4) The Zip reaction for the transformation of -1-(3-aminopropyl)-3-methylazecan-2-one 8 to -7-Methyl-1, Sdiaza-cyclotetradecan-6-one 9 were undertaken. The results showed that, under controlled conditions, acceptable yields (43%) could be achieved and racemization can be minimized during the ring expansion reaction.

该合成路线与文献方法相比，反应条件较温和，也缩短了反应时间；(2)哌啶衍生物2与乙烯基格氏试剂进行加成反应的条件和立体选择性，取得了较好的结果（差向异构体比为80：20，产率95％左右）；(3)不饱和哌啶衍生物7在不影响碳碳双键的情况下去除苯基甘氨醇手性辅助基的条件；(4)具有羰基α位手性的氨基酰胺8在不同条件下经Zip重排反应转变为9的反应，控制反应条件，可使反应中消旋化减小到最小的程度。

NAC also blocked the up-regulation of TGF-β in in vivo model of VILI. Conclusion TGF-β1 and TGF-β2 were up-regulated in VILI. Oxidant injury mediated up-regulation of TGF-β in VILI. NAC, which attenuated oxidant injury and blocked TGF-β up-regulation in VILI, could be a future therapeutic strategy in VILI.

结论TGF-β1和TGF-β2在通气机所致肺损伤中的表达增加并在血清中上调；TGF-β上调的机制与氧自由基损伤有关但与肿瘤坏死因子无关；N-乙酰半胱氨酸可对抗氧自由基损伤，能阻断TGF-β的上调，可能成为呼吸机相关肺损伤的一种新治疗途径。

Protein nitrogen accumulation in leaf-stems of Yuchi 231 was significantly lower than those of 4434 and Dianrui 302, while that was significantly higher in grains, suggesting higher nitrogen accumulation in grains was a key characteristics of the rice genotype with high NHI.

余赤231灌浆期叶片和籽粒谷氨酰胺合成酶和谷氨酸合成酶活性显著高于4434和滇瑞302，有利于叶片游离氨基酸合成及外运，使得穗颈节伤流强度和游离氨基酸含量升高，为籽粒氮素积累提供了物质基础；同时，较高的籽粒Gs和GOGAT活性促进了籽粒蛋白质合成，提高了NHI。

PBMC treated with inhibitor N-tosyl phenylalanine chlormethyl ketone, Astragalus can increase the activity of NF-κ B and the concentration of IL-8 in patients with PNS. it also increases the the activity of NF-κ B in normal children , but can ' t affected the concentration of IL-8 in normal children. ConclusionIn patients with PNS , the activity of NF-κ B was up-regulated and the level of IL-8 was significantly elevated.

结果肾病患儿 NF-κ B 活性及 IL-8含量增高，2者呈正相关； IL-1β刺激后，黄芪降低肾病患儿 NF-κ B 活性及 IL-8含量、降低正常儿童 NF-κ B 活性而不影响 IL-8含量；用对甲苯磺酰-L-苯丙氨酸氯甲基甲酮抑制后，黄芪可提高肾病患儿 NF-κ B 活性及 IL-8含量、提高正常儿童 NF-κ B 活性；而不影响 IL-8含量。
