应用PCR—SSCP技术从显微切割的人染色体17q11—12探针池批量分离单拷贝片段的研究

将ＤＮＡ单链构象多态（ＳＳＣＰ）检测的原理，应用于“显微切割的人染色体１７ｑ１１—１２探针池”批量分离单拷贝片段，取得了很好效果。从筛选出的７４个次级单拷贝中有效地鉴定出３７个非同源的单拷贝片段。这比传统的仅限于长度比较而确认的非同源单拷贝片段（１２个）多出２５个．其中部分已经ＤＮＡ测序证实。结果提示：采用ＳＳＣＰ技术区分相似分子量单拷贝片段的同源性，可显著地提高从“显微切割探针池”分离和克隆非同源单拷贝片段的效率。本文还将一部分单拷贝片段作为探讨，与人基因组ＤＮＡ的限制性片段作Ｓｏｕｔｈｅｒｎ印迹杂交，结果均只显示单一杂交带，说明单拷贝ＤＮＡ片段的结论是可靠的。     

外源类固醇激素对中国对虾幼体蜕皮和生长影响的初步研究

本文报告了１７一α一甲基睾丸酮和１７β一雌二醇两种类固醇激素对中国对虾幼体蜕皮和生长的影响。通过投喂含有激素的饵料进行实验，结果表明：与对照组比较，１５天实验中，１７α一甲基睾丸酮和１７β一雌二醇实验组幼体分别提前２天和１天全部进入仔虾期；１６天实验中，后１０天（第７天到第１６天）１７α一甲基睾丸酮实验组幼体生长明显加快（Ｐ＜．０５），１７β一雌二醇实验组幼体生长无显著变化（Ｐ＞０．０５）。     

十七大前瞻：扩大党内民主的核心价值诉求

扩大党内民主是十七大的核心价值诉求。党内民主已成为党的监督制度：以党内民丰带动人民民主，是中国推进政治体制改革的新思维；加快民主进程要走群众路线，以巩固党的执政根基；完善党自身的民主制度建设，以程序民主保障制度民主、政治民主的真正实现。     

Transforming growth factorβ1 and epidermal growth factor decrease the expression of 17β-hydroxysteroid dehydrogenase type 2 in endometrial carcinoma cells

Estradiol (E2) is the major molecular form of estrogens. Its biological effects are determined by estrogen receptors and intracellular E2 concentration in target cells. Regulation of intracellular E2 concentration involves the action of 17β(-hydroxysteroid dehydrogenase (17HSD) type 2, the enzyme inactivating E2 to estrone. It has been demonstrated that 17HSD type 2 is expressed in normal endometrial epithelia and emdometrial carcinoma cells (RL 95-2). However, the regulatory mechanism of 17HSD type 2 expression in emdometrial cancer cells remains unknown. In the present study, the effects of transforming growth factor-(1 (TGF-β1) and epidermal growth factor (EGF) on 17HSD type 2 expression in RL 95-2 cells have been investigated using enzyme activity assay and Northern blot analysis. After stimulation with TGF-β1 or EGF, the in vivo oxidative 17HSD activity in RL 95-2 cells was significantly decreased. It appeared that the inhibitory effect of TGF-β1 and EGF on the enzyme activity of 17HSD type 2 is dose- and time-dependent. Northern blot analysis further revealed that treatment of cells for 48 h with 10 ng/mL TGF-1β And 50 ng/mL EGF reduced the expression 17HSD type 2 mRNA to 30% and 20% of the control level, respectively. The data demonstrate that 17HSD type 2 expression in endometrial carcinoma cells is down-regulated by certain growth factors.     

Analysis of EET on Ca increasing the melting point of Mg17Al12 phase

The present investigation showed that the additions of Ca to the alloy AZ91 were mainly dissolved into the Mg₁₇Al₁₂ phase and increased its melting point and thermal stability, which would have great effects on the high-temperature properties of AZ91 alloy. The empirical electron theory (EET) of solid and molecules was used to calculate the valence electron structures (VES) of Mg₁₇Al₁₂ intermetallic compound with and without Ca addition. The results showed that Ca dissolving in Mg₁₇Al₁₂ phase increased the strength of bonds that control the thermal stability of Mg₁₇Al₁₂ phase. Additions of Ca also made the distribution of the valence electrons on the dominant bond network more uniform in the whole unit cell of Mg₁₇Al₁₂. The theoretical conclusions well account for the experimental results.
