White sesame E-zhi NO.2 and black sesame Zhong-zhi NO.9 were sowed at intervals as comber-sesame and autumn-sesame. The temperature and sunlight-length of different growing-stage. The result showed that seedling-stage and bud-ding-stage were temperature-sensitive and weak phototonus and temperature was the main factor in the compositive effect of temperature and light. The temperature range of 27~31℃ was optimal for sesame to produce more flowers and prolong the flowering days, but the length of flowerig-stage and practical sunlight-hour had no correlativity.

用白芝麻品种鄂芝2号和黑芝麻品种中芝9号分期进行夏播和秋播，使两个品种各生育阶段处於不同的光温条件下，用试验当年相应时段的温度和实际日照长度对芝麻各生育阶段的发育特性进行相关分析结果表明：芝麻苗期和蕾期感温性强，感光性较弱，在光温综合作用中，温度是主要因子；芝麻开花最适应的温度为27~31℃，该温度有利於多开花和延长开花期天数。

Viral infection of the host cell may be switched on by the specific and stable combination of one or several viral envelope protein with one or several glycoprotein receptors available on the cell membrane, which is followed by viral pinocytosis or viral fusion with cell membrance, viral deenvelope, viral particle movement from cytoplasm towards nucleus and the viral gene passage.

病毒感染细胞可能是通过一个或几个病毒包膜蛋白与一个或多个细胞膜上的糖蛋白受体特异稳定地结合而启动，通过病毒胞饮作用或者病毒与胞膜融合、病毒脱包膜、病毒粒子从胞浆到胞核的运动和病毒基因通过核膜的传代将会发生；但参与这些动力过程相关的病毒、细胞结构和生化因子仍不清楚。

BACKGROUND: Based on the multi-directional differentiation potential,the combined application of proper biological materials and growth factor can repair tissue defect.

The relationship between the genetic deficiencies and hemorrhagic disorder were characterized. The homozygosity of the Thr359Met in the propositus with FⅦ: C activity 2% was related to severe clinical symptoms; The proband with double heterozygous lesions of Arg152Leu and one single nucleotide deletion at position 11487-9, combined with Arg304Trp in exon 8 with FⅦ activity 1% suffered severe clinical bleeding tendency. one proband with double heterozygous mutations (Agr304Trp and Arg304Gln) with 10% of FⅦ activities characterized asymptom. the heterozygous mutations (Thr359Met, Arg152Gln,-55C→T) with FⅦ: C 1%～5. 5% showed moderate or mild clinical symptoms.

其中8961 G＞T（Arg152Leu）和10966-8delC两种突变为国际首次报道，IFSla+5g＞a突变导致的异常剪接为国际首次报道。1个F7及F10基因联合缺陷家系，其中，F10基因28139 G＞T（Val384Phe）突变为国际首次报道；发现了1个由F7及组织因子(tissue factor，TF)两种基因联合缺陷导致的出血家系，其突变分别为F7基因启动子区-55C＞T杂合突变；TF 9363 C＞T（Arg131Trp）杂合多态性（频率2.63％）。6种F7基因突变发生在催化区；2种突变发生在裂解位点；1种发生在启动子区；1种突变发生在剪接位点，除一种缺失突变外，其余均为点突变；所有家系的基因突变都来自先证者的父亲和/或母亲。

The effect of meteorological factors on the rats density could be evaluated by RSM model. This model was superior to linear regression model. The effect of meteorological factors on rats density was resulted from multiple factors and their interaction.

响应面分析法能够较好地应用于气象因子对鼠密度的影响，建立的响应面模型优于多元线性回归，气象因素对鼠密度的影响是多因素及交互作用的结果。

However, the mutated isoform of UGT2B7 was a risk factor for developing bladder cancer in benzidine exposed Chinese workers.

然而，在中国联苯胺暴露个体中UGT2B7 C802T(H268Y)的突变了的多态性是决定暴露个体的膀胱癌易感性的一个风险因子。

Objective: To explore the role of hypoxia-inducible factor-1α(HIF-1α) in formation of multidrug resistance induced by microenvironment and to find a new and effective molecular target on preventing and reversing chemoresistance in hepatocellular carcinoma.

目的探讨缺氧诱导因子1α(HIF-1α)在微环境诱导的肝癌多药耐药表型形成过程中的作用和地位，并为预防和逆转肝癌耐药提供有效的新的分子靶点。

While PcG proteins are best known for the roles in maintaining the correct expression pattern of key developmental regulators, such as Hox genes, there is accumulating evidence that they are also involved in the regulation of cell proliferation and tumorigenesis.

众所周知，PcG蛋白可以维持关键的发育调节因子如Hox基因的准确表达模式。而且，现在越来越多的证据现实，PcG蛋白也参与了对细胞增殖和肿瘤发生的调节过程。
