The article focuses on the aberrant expression and significances of proto-oncogenes, tumor suppressor genes and genes associated with the proliferation process of gastric cells such as telomerase, transcription factor and cyclooxygenase, etc. These genes, alone or synergically, participate in gastric cancer cell proliferation, resulting in an uncontrolled growth characterized by over-proliferation of decreased apoptosis of gastric cancer cells.

本文着重阐述了与胃癌细胞增殖过程密切相关的端粒酶、核转录因子、环氧化酶等基因以及参与细胞周期调控的原癌基因、抑癌基因的异常表达及临床意义，这些基因或单独作用，或相互协同，参与胃癌细胞的增殖，使肿瘤细胞生长以增殖过多、凋亡过少的失控性生长为特征。

During the past 3 years, 2 independent experiments of sperm-mediated gene transfer in domestic silkworms were carried out respectively in 2000 and 2002 with the method direct injection of copulation thecae.

在同源重组绿色荧光蛋白表达载体pG350的基础上，以pMD18-T为质粒载体，用egfp基因替换gfp基因，构建了家蚕核型多角体病毒早期即刻蛋白基因启动子BmNPV-IE控制下的增强型绿色荧光蛋白表达载体pMD-Fib-IE-EGFP。

Results: Both phosphorothioate-modified oligonuclotides and oligonucleotides complementary with telomerase UNA template inhibited telomerase activity. And application of the tow ODNs together increased the inhibition activity in upfold.

结果：硫代磷酸酯寡核甘酸和RNA模板反义ODNs都可以抑制端粒酶的活性，且可产生累积效应。

In vitro associstion experiments indicate that the plasmid pAy6.8 containing the core region of Antheraea yamamai fibroin gene can tightly bind to the nuclear matrix of Bombyx mori fertilized eggs,and recognize the same binding sites of homogeoous MAR fragments.

体外结合实验表明，携带天蚕丝素基因核心区的质粒pAy6.8可与家蚕受精卵核基质紧密结合，而且同内源MAR片段竞争结合位点。

Hollow microspheres are one kind of new material in nano- or micro- size with core-shell special structure whose core is hollow while the shell is bestrewed with pores.

中空微球是粒径为纳米到微米级的一种具有核-壳特殊结构、核心中空而壳上布满孔道的新型材料。

The coagulating mechanism of polysilicate-containing composite inorganic polymer flocculants was discussed by studying the Zeta potentials of flocculants and contaminants,the growing processes of flocculates,and the sizes of flocculates.

通过测定含硅多核无机高分子絮凝剂水解沉淀物和废水中污染物的Zeta电位、絮体粒径及不同絮凝阶段的絮体显微照片，并结合絮凝剂的形貌结构和混凝性能探讨了其混凝机理。

Core composed of interpenetrated polymer networks formed by different chains and the shell was composed of poly- acrylate.

由不同链段组成的互穿网络结构构成了乳胶粒的核，而壳则更多地由聚甲基丙烯酸酯链段组成。

The infected cells were cultured for 72h, then lysed and determined for luciferase content.

结果 HIV-1的B/C重组亚型和C亚型Envelope基因真核表达质粒分别与pNL4-3。

Necropsies were performed at 21 days post-challenge, the lymph nodes in the nonvaccinated but challenged pigs were larger than those of vaccinated pigs. The PCV2 genomic copy loads in lymph nodes were reduced in vaccinated pigs. Moderate amounts of PCV2 antigen were detected in most lymphoid tissues of nonvaccinated pigs. These data indicated that when given intramuscularly in pigs, the chimeric PCV1-2 live virus and recombinant plasmid induces protective immunity against PCV2 infection and could potentially serve as an effective vaccine.

攻毒后21天攻毒对照组猪淋巴结比免疫组猪显著肿大，免疫组猪血清、淋巴结中PCV2病毒载量低于对照组，攻毒对照组猪淋巴结中PCV2抗原含量高于免疫组，这些结果表明嵌合型猪圆环病毒PCV1-2及真核表达质粒肌肉注射免疫商品猪后，对PCV2感染能产生保护性免疫应答，有可能成为候选疫苗。

The child swallowed a cherry, stone and all.
