目的：观察并比较子宫全切术应用腰硬联合麻醉不同穿刺法的麻醉效果。方法随机选取2012年1月~2013年12月在本院择期接受子宫全切术治疗患者106例，按照完全抽样法1：1分成两组，对照组53例采用单间隙腰硬联合麻醉，研究组53例采用双间隙腰硬联合麻醉，比较两组的生命体征指标、麻醉效果与综合疗效。结果麻醉后10 min、进腹探查及牵拉时，两组的HR及MAP分别进行比较，差异有统计学意义（P〈0.05）；对照组进腹探查与牵拉时的HR与MAP均显著低于麻醉前，研究组麻醉后5、10 min的MAP显著低于麻醉前，差异有统计学意义（P〈0.05）。研究组麻醉起效时间长于对照组，麻醉维持时间与消退时间短于对照组，差异有统计学意义（P〈0.05）。研究组麻醉平面对称率高于对照组，牵拉反应、追加用药、低血压与心动过缓发生率均低于对照组，差异有统计学意义（P〈0.05）。结论子宫全切术应用双间隙腰硬联合麻醉患者的生命体征更稳定，具有较高的安全性。

INTRODUCTIONThe mechanism of hepatocellular carcinoma(HCC)is still unclear,although some genes have been found to play a role in the transformation of liver cells,and a variety of studies have described differences in gene expression which distinguished tumor from nontumor[1-6].The new genes,especially the functional genes directly related with tumor are still worth being *** purpose of our study is to find the different genes between human liver tumor and normal tissues using suppression subtractive hybridization.

党的十八大五中全会将生态文明建设作为重要发展战略,但生态文明建设的重点"水污染治理"依旧处于困境之中。水污染治理的难点在于水污染规制策略执行人——地方政府与其他利益主体理性目标的差异。基于地方政府间博弈竞争的分析框架,引入中央政府约束和激励机制,分析地方政府间对于水污染规制博弈策略的动态演进行为。研究结果表明,水污染的外部性不会影响地方政府间博弈策略;政府可以通过提高水污染指标在地方政府政绩考核权重,降低水污染规制成本,减弱企业利润对地方政府支付水平的影响程度,构建约束和激励机制来防止地方政府间的博弈陷入"囚徒困境",促使地方政府水污染规制策略的高效执行。

Mianzhu--Aba profile, east of the Tibetan Plateau, was selected to study the occurrence of organo- chlorine pesticides （OCPs） along an altitudinal gradient. Dichlorodiphenyltrichloroethanes （DDTs）, hexachlorocy- clohexanes （HCHs） and Aldrin, Dieldrin and Endrin （Drins） in surface soils were detected in winter （March） and summer （July）. Soil concentrations （ng.g-1, dw） in winter and summer ranged as follws： DDTs, 0.37-179.16 and 0.32-42.57; HCHs, 0.14-10.76 and 0.55-32.71; Drins, N.D-3.99 and 0.02-6.93, respectively. Main soil OCPs were p,p＇-DDT, p,p＇-DDE, fl-HCH and Drins, among which Drins were rarely reported in current literature of the Tibetan Plateau. Higher OCP concentra- tions in the profile were attributed close to the agricultural fields of the Sichuan Basin, current lindane and non- dicofol DDTs inputs, and also long-range atmospheric transport from abroad. Soil OCP concentrations underwent obvious seasonal variation, with higher DDTs in winter and higher HCHs and Drins in summer. It may be caused by climatic conditions, summer monsoon type, and physico-chemical properties of such contaminants. Though ＂rest＂ phenomenon occurred in some sampling sites, HCHs and Drins showed an increasing trend with increasing altitude, while DDTs showed an evident decrease with increasing altitude. The altitudinal distribu- tions of OCPs were all consistent with previous findings in other mountainous regions. A primary fugacity analysis on OCPs soil-air exchange indicated that the profile may be secondary sources for HCHs and Endrin. As with Aldrin,Dieldrin, and DDTs, the profile may be both secondary sources and sinks.

(E)-b-Farnesene (EbF) synthase catalyses the production of EbF, which for many aphids is the main or only component of the alarm pheromone causing the repellence of aphids and also functions as a kairomone for aphids’ natural enemies. Many plants possess EbF synthase genes and can release EbF to repel aphids. In order to effectively recruit the plant-derived EbF synthase genes for aphid control, by using chloroplast transit peptide (CTP) of the small subunit of Rubisco (rbcS) from wheat (Triticum aestivum L.), we targeted AabFS1, an EbF synthase gene from sweet wormwood (Artemisia annua L.), to the chloroplast of tobacco to generate CTP t AabFS1 transgenic lines. The CTP t AabFS1 transgenic tobacco plants could emit EbF at a level up to 19.25 ng/day per g fresh tissues, 4–12 fold higher than the AabFS1 transgenic lines without chloroplast targeting. Furthermore, aphid/parasitoid behavioral bio-assays demonstrated that the CTP t AabFS1 transgenic tobacco showed enhanced repellence to green peach aphid (Myzus persicae) and attracted response of its parasitoid Diaeretiella rapae, thus affecting aphid infestation at two trophic levels. These data suggest that the chloroplast is an ideal subcellular compartment for metabolic engineering of plant-derived EbF synthase genes to generate a novel type of transgenic plant emitting an alarm pheromone for aphid control.
