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。

Based on a thorough analysis of the experimental results, a coupling mechanism of the catalytic selective oxidation and non-catalytic partial oxidation in which the surface adsorbed 〓 species and the lattice 〓 species take part synergically.

在全面分析实验结果的基础上，提出了一个由表面吸附氧种〓和晶格氧种〓协同参与的甲烷催化选择氧化与气相非催化部分氧化相耦合的反应机理，催化剂的参与既在表面开辟了生成〓和HCHO的新途径，又可将气相反应中的强氧化型物种转移到催化剂表面，形成有利于选择氧化的表面活性氧种，同时避免了气相中强氧化型物种浓度过高而导致选择氧化产物深度氧化。

本研究的目的，在於观察与纪录当前国内地方民众参与城乡风貌发展的经验，从中提出一系列如何达到好的参与行为之影响因素。

However, most experimental evidence is indirect and unassembled. In this paper the studies on LDH-C and energy metabolism of mammal spermatozoa were reviewed, We suggested that LDH-C played the multi-roles in energy metabolism of mammal spermatozoa, not only in directly the energy metabolism pathway but also in the signal pathway of spermatozoa.

综述了对哺乳动物精子能量代谢和LDH-C两个方面的研究，提出LDH-C在精子的能量代谢中扮演着多重角色，不仅直接参与精子的能量代谢，还可能参与哺乳动物精子获能的信号途径，LDH-C和哺乳动物精子的能量代谢密切相关。
