1,After transfected the mutated mtDNA of colorectal carcinoma,the mtDNA D-loop region of the transfected cells displays new mutation points.2,The external source pieces of the mutated mtDNA can integrate to nuclear genome after transfection.3,There's no differences in apoptosis between combinations after transfected the mutation of mtDNA in NIH3T3 and LST cells.4,The mutated mtDNA may affect the action mechanism of occurrence and development in colorectal carcinoma through affecting its mtDNA mutation or integrating exogenetic mtDNA to its nuclear which may cause the abnormal expression of oncogene or anti-oncogene.

Then the comprehensive diagenetic facies of the upper Triassic Xujiahe Formation are suggested also. It is concluded that that the compactionfracturesiliceous cementation facies of the thrust belts and the compactiondissolutionchlorite coating facies of foredeep zones are more favorable for hosting oil.

冲断带发育的压实-破碎-硅质胶结成岩相、近前渊三角洲相砂体中发育强压实-溶蚀-绿泥石衬边胶结成岩相和前隆带三角洲相中发育的中压实-溶蚀-绿泥石衬边胶结相均可形成较好的储层。

What was observed under a light microscope included: tumor cells were mulberry and micropapillary shaped or were of glandule tubular arrangement; there was obvious interspace between cancer nest and neighboring areas; micropapillary was empty of fiber blood vessel axes, with micropapillae floating freely in spongy spaces and separated by fibrous septa.

光镜下特征性表现为肿瘤细胞呈桑椹状、微乳头状或小腺管样排列，癌巢与周围间质形成明显的空隙，微乳头缺乏纤维血管轴心，每个微乳头细胞团和周边的纤维组织均存在无细胞的间隙样结构；瘤细胞CerbB-2、CgA和EMA。

Associated minerals are primary glauberite, halite and terrigenous mud; while calcite is absent or rare. The X-ray diffraction analysis shows that the mud-sized crystalline dolostone has an average CaCO3 mole content of 57.30% and an average degree of order of 0.40, revealing the characteristics of higher calcium content and lower degree of order. It is closely intergrown with glauberite, indicating that the aqueous medium in the depositional environment of mud-sized crystallinedolostone was hypersaline water or dilute brine. The temperature of water in the depositional environment calculated according to the oxygen isotope data averaged 30.5℃ and the minimum homogenization temperature of inclusions in primary glauberite crystals associated with mud-sized crystalline dolomite was 44℃. The two groups of temperature data are close, indicating that the temperature of the water in the paleolake environment during the deposition of mud-sized crystalline dolostone ranged from 30.5℃ to 44℃.

泥晶白云石在阴极发光下呈红色、橙红色，与其伴生的矿物除原生钙芒硝、石盐、陆源泥质外，方解石没有或极少；X衍射分析结果表明，泥晶白云石的CaCO3摩尔含量平均为57.30%，有序度平均为0.40，具高富钙、低有序的特征；与钙芒硝岩的紧密共生，说明泥晶白云岩沉积环境的水介质为高盐度的咸水或淡卤水；根据氧同位素数据计算的沉积环境的水体温度平均为30.5℃，与泥晶白云石伴生的原生钙芒硝晶体中的包裹体均－温度最低值为44℃，这两组温度数据基本接近，表明泥晶白云石沉淀时环境水体的温度大致在30.5-44℃之间。

The straight gneisses have the plane-straight gneissic; beating a few, fine and plane-straight felsic streaks; the mineral stretching lineation; as the S-L tectonite with the features of finer mineral grain size (1mm±), uniform grain size grade and bad directional, showing the ultra-plastic flow mechanism.

强直片麻岩发育平直的片麻理，长英质条带含量相对较低，但细而平直，发育矿物拉伸线理，为S-L构造岩，矿物粒度相对较细(1mm±)，粒级均匀，定向性差，均反映出强直片麻岩的超塑性流动变形机制特征。

Observation was made on the content of malondialdehyde. Results Compared with MC group, the increases of MDA content in the membrane induced by XanXO system, H2O2 or UV light in all of the three Punica granatum L.group were inhibited dosedependently.
