合方治疗脑缺血24小时组缺血脑组织nNos光密度值较缺血24小时模型组明显降低（p＜0.01）。细胞的死亡分为坏死和凋亡两种方式，凋亡是细胞为避免对机体造成更大损伤而采取的一种程序性的死亡方式。珍珠母、胆酸、栀子苷、黄芩苷、合方治疗组较脑缺血24小时模型组可明显降低P53阳性表达，考虑药物抑制细胞凋亡可以起到对缺血脑组织的保护作用。

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.

结果 缺氧缺血后大鼠相继表现为烦躁不安、全身发给、呼吸加深加快、站立不稳、嗜睡、激惹或间断发作的痉挛和抽搐；HE染色显示实验组大鼠左侧大脑皮层出现局灶性神经元核固缩，核碎裂，核仁偏位，不清或消失，基质疏松；中药组大鼠脑组织结构基本接近假手术组，无明显水肿和坏死表现；实验组和中药组大鼠脑组织HIF-1α mRNA表达较假手术组明显增加，尤其是中药组实验第3日者；免疫组化显示实验组和中药组各时间点大鼠大脑皮层和海马区均可见不同程度的HIF-1α表达，明显高于假手术组，阳性表达主要在血管内皮细胞，海马和皮层的锥体细胞亦有HIF-1α阳性细胞分布。

Cell apoptosis is an important factor in the cell necrose following the skeletal muscle damage. The apoptosis relative genes such as Bcl-2, Bax are crucial in skeletal muscle cell spoptosis. Adaptation and damage are two dichotomal facets in daily physical exercise and military training.

细胞凋亡是骨骼肌损伤后细胞发生坏死过程中的重要作用因素，如凋亡相关基因：Bcl-2、Bax等在骨骼肌细胞凋亡过程中起着非常重要的作用。

Results The main pathologic changes of high dosage group were inflammatory cell infiltration into the tissues around injecting location, subarachnoid space, and ependyma.

高剂量组动物脑组织主要病理改变为给药部位周围脑组织、蛛网膜下腔、室管膜的炎细胞浸润，炎细胞主要以胶质细胞、单核、淋巴细胞为主，没有脑组织的变性坏死。

To further prove the function of TGF-βWe added the exogenetic TGF-βto observe its effect on the regulation of proliferation, diffrentiation and apotosis of the human pulp cell induced by LPS.

提示LPS对人牙髓细胞损伤是通过抑制牙髓细胞增殖、介导其凋亡、造成其坏死等多种途径实现的，牙髓细胞凋亡可能是细菌感染造成牙髓组织损伤的重要形式。

Histological observation showed no vital osteocytes were found in bone lacuna and vessels perforating into Haversian canals disappeared in control group after operation.

细胞和矿化的细胞间质组成的骨组织有其独特的生物组织学特性，为人体最坚硬的结缔组织，即使其细胞成分全部坏死，仍可在一定的时期内保持其组织学结构形态，且仍具有一定的生物力学功能。

［Objective］To study the relativity during polyethelene debris cytokine and loosening of hip prosthesis.［Methods］Thirty eight patients with loosening of hip prosthesis were divided into three group:total hip arthoplasty,double hip arthoplasty and integrated arthoplasty.The inflammative reaction was analyzed with light microscopic observation arrording to the half-ration standard of Joseph,and the content of TNF in samples of interface membranes was determined.

［目的］研究聚乙烯微粒、细胞因子与人工髋关节松动的相关性［方法］根据假体的类型及假体中是否含有聚乙烯将38例人工髋关节翻修病例分 3组：全髋置换组、双动头组和体式单动头组，对各组术中松动假体周围界膜组织进行光镜下炎性细胞计的半定量分析和肿瘤坏死因子的测定，分析人工髋关节无菌性松动与聚乙烯微粒、细胞因子之间的相关关系。

Microscope examination:in group a,at 2 weeks,a few inflamatory cells appeared in the holes with many osteoblasts and ostoid appeared around the drilled holes.at 8 weeks,marrow formed in the drilled holes in group b,at 2 weeks,there were a large amount of osteoblasts in the drilled holes and some ostoid formed around thc drilled holes.at 4 weeks,the drilled holes were full of trabeculae.at 8 weeks,the trabeculae matured with the marrow appeared in the intertrabecular space.

组织学结果：2周时a组钻孔区出现少许炎症细胞，边缘出现较多成骨细胞并有骨组织形成，至8周时，钻孔区内形成骨髓组织，只在边缘形成骨小梁结构。2周时b组钻孔区有大量的成骨细胞，边缘有较多骨组织形成，4周时钻孔区内充满新生骨小梁结构，8周时钻孔区内骨小梁成熟，小梁有骨髓组织填充。［结论］骨髓基质干细胞对兔股骨头缺血性坏死有良好的修复作用。
