Results: Neonatal rats in hypoxic-ischemicgroup behaved restlessness, cyanosis, deep and rapid breath, astasia, lethargy, irritation and spasm; There were local pyknosis, fragmentation, dissymmetry, blur or disappearance of nucleoli, raritas of ground substance in left cerebral cortex; but there was no statistic significance in chinese traditional medicine group and sham group. The expression of HIF-1α mRNA in brain tissue of experimental group and chinese traditional medicine group were higher than that in sham group, especially chinese traditional medicine group at 3d; HIF-1α positive cells were found in cerebral cortex and hippocampus. There were more HIF-1α positive cells in experimental group and chinese traditional medicine group and mainly in vascular endothelial cells.

At 4 weeks following implantation, cells on the surface of coralline hydroxyapatite were found and connective tissues were seen in the material pores in the experimental group. Cells on the coralline hydroxyapatite were observed only in the control group. At 8 weeks, new bone formation was detected on the surface of coralline hydroxyapatite; bony tissue deposition and a few chondroid tissues were found in the pores or surrounding the pores in the experimental group. A few fibrous connective tissues were observed in the control group. At 12 weeks, abundant mature woven bone was detected on the surface of coralline hydroxyapatite; medullary cavity-like structure and vessels were found in some regions in the experimental group. No new bone or bony tissues were found in the control group.

植入材料后4周，实验组可见珊瑚羟基磷灰石表面有细胞生长，孔隙内有结缔组织长入；对照组仅见珊瑚羟基磷灰石表面有细胞生长。8周时珊瑚羟基磷灰石表面有新生骨形成，孔隙内和孔隙边缘可见骨样组织沉积和少量软骨样组织形成；对照组仅见少量纤维结缔组织长入。12周时珊瑚羟基磷灰石材料表面有较多成熟编织骨形成，部分区域可见髓腔样结构形成，并有血管长入；对照组仍未见新骨及骨样组织形成。

Through upregulating the production of MMPs in deciduas and chorionic villi, the upregulation of the expression of EMMPRIN in syncytiotrophoblast and cytotrophoblast column of the villi in the threatened abortion can degenerate deciduas and denudates embryo.

发生先兆流产时合体滋养细胞、细胞滋养层柱所表达的EMMPRIN增强可能通过上调绒毛及蜕膜组织中基质金属蛋白酶的水平，降解细胞外基质，使绒毛剥离、蜕膜组织剥脱。

However, another investigation12 using the immunolocalization of MMP1, MMP2, MMP9, and MMP14 (MMP14 is a membrane-bound MMP) showed elevated levels of MMP2 and MMP14 in macrophages, as well as in the type II cells and fibroblasts, in emphysematous, compared to nonemphysematous, tissue.

但是在另一项对MMP 1，MMP 2和MMP 14（MMP 14 为有膜MMP）的免疫定位的研究中发现，气肿性组织较非气肿性组织而言，巨噬细胞中的MMP 2与MMP 14水平有升高，II型细胞和层纤维细胞亦如此现象。

Fibroplastic proliferation was observed at 14th days and later.

肝脏碘油栓塞HIFU损伤后即刻损伤组织表现为肝细胞结构破坏，肝细胞核固缩。3天后坏死区与正常组织分界清楚，坏死区细胞完全破坏。14天出现明显增生的纤维结缔组织，包绕坏死组织。

The digestion process includes the following steps: adding 0.15 % concentration collagenase II solution compounded with DMEM into blood vessel smooth muscle tissue block and acting in water bath for 1.5 hr until forming floccular tissue; cleaning with 0.02 % EDTA solution, adding 0.125 % trypsase solution and water bath vibrating to digest at 37 deg.c to obtain dispersed smooth muscle cells; terminating enzyme action with 10 % new born ox serum culture liquid; regulating cell concentration with 20 % new born ox serum culture liquid to 50,000-500,000/L, inoculation, and culturing in culture tank with 5 % CO2 and first 37 deg.c to cell fusion of 70-80 %; and subculturing conventionally.

向血管平滑肌组织块中，加入用DMEM配制的0.15％胶原酶II溶液，水浴箱中作用1.5h，至组织呈絮状，用0.02％的EDTA清洗，然后，加入0.125％胰蛋白酶溶液，于37℃水浴振荡消化，即可得到分散的平滑肌细胞，用10％新生牛血清的培养液终止酶的作用。加入含20％新生牛血清的培养液，调节细胞密度为5×104～5×105个/L，接种，放入5％CO2、37℃培养箱中培养。当细胞达到70％～80％融合时即可按常规方法传代。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
