Acellular allogeneic dermal matrix is the dermal replacement of heterogenous human skin in which the cellular elements have been removed by special technique and basement membrane complex have been remained. It becomes a kind of 3D porous acellular dermal scaffold. It supports fibroblast infiltration, neovascularization and epithelialization in the absence of an inflammatory response.

异体脱细胞真皮基质（acellular allogeneic dermal matrix， ADM）来源于正常的异体皮肤组织，经过特殊的理化处理去除真皮中的细胞成分，保留原有的胶原三维结构和完整的基底膜，成为一种多孔的三维膜性支架，其空间网状结构有利于细胞的增殖、毛细血管增生，加速组织的愈合过程，移植后可以迅速被血管化和自体细胞重建。

The characteristical time-dependent expression of transcriptional factors HNF4α, C/EBPα, and C/EBPβ during the hepatocyte differentiation by bone marrow stem cells demonstrates that the expressions of these transcriptional factors are closely related to the initiation and maintenance of hepatocyte differentiation.

结论在肝细胞分化过程中，转录因子HNF4α、C/EBPα和C/EBPβ呈特征性时序表达，表明骨髓间充质干细胞在向肝细胞分化时，肝细胞相关转录因子的表达与细胞分化的启动和维持密切相关。

Results By using optical microscope,the neurocytes of hippocampus in experimental group were observed to denaturalize,tumefy,destroy and disappear.And under electron microscope,the karyon was irregular,nucleoles deviated,chondriosome tumefied,crista collapsed,membrane was damaged,substance cavitated.Such changes were more evident with the increased paroxysm of epilepsy,the parameters between control group and operation group had no difference（P＞0.01）.But make a monofactorial variance analysis among cells' number,area,circumference and integral optical density in different groups,it showed that there were significant differences between optional two groups（P.01;at the same time,the more serious injury in hippocampus,the more powerful GFAP immunoreaction was.

结果： 实验组海马区光镜下可见神经细胞变性、肿胀、坏死及神经细胞脱失改变，电镜可见细胞核形态不规则、有切迹、核仁偏位、线粒体肿大、嵴断裂、膜破损和基质空化等改变，随癫痫发作次数增加上述改变越明显，对照组与手术对照组比较，各参数差异无显著性（P＞0.05），将不同组别大鼠细胞数、面积、周长、积分光密度分别作单因素方差分析，不同组别间均差异有显著性（P.01），同时观察到海马区GFAP免疫反应阳性的胶质细胞随海马损伤的加重而GFAP免疫反应增强。

And their CD4+CD25+ Tregs in PB and MLN were much more than the model control group at the end of one or two weeks after treating with SASP and CLYSTER No. 1. Conclusion: CD4+CD25+ Tregs with strong immune suppression could play a central role in the initiation and development of mouse experiment colitis, and the CLYSTER No. 1 might exert its therapeutic effects on UC by the regulation of number and function of CD4+CD25+ Tregs.

具有较强免疫抑制作用的CD4+CD25+Tregs细胞亚群在小鼠实验性溃疡性结肠炎的发病及病情转归中可能具有重要免疫调节作用，中药灌肠1号通过调节Tregs细胞的数量对溃疡性结肠炎发挥治疗作用。

In the prediction of protein structural classes, the residue order along the sequences takes an important role; while as in the prediction of protein subcellular locations, the amino acid composition is the most important factor.

在蛋白质的亚细胞定位预测中，氨基酸组成仍然是最重要的特征，蛋白质的亚细胞位置与序列同源性的关系没有结构与序列同源性的关系强。

Objective To investigate the correlation between the conspicuity of local hepatic lesions on feridexs-enhanced MR images and the number of Kupffer cells in the hepatic lesions in histopathologic findings, as compared with that in the background liver.

结果良、恶性肝内局灶性病变间Kupffer细胞比率差异有统计学意义，随着HCC分化程度的降低，病灶内Kupffer细胞计数比率呈下降趋势(P05)。T2WI强化比率与Kupffer细胞计数比率呈负相关(r=-0780，P05)；T1WI强化比率与Kupffer细胞计数比率呈正相关(r=0389，P05)。

In the pathological proceeding of pulmonary fibrosis, myofibroblast plays an important role, such as: the abnormal extracellular matrix deposition causing by the remarkable capability of collagen synthesis, derogation of the lung compliance owning to the contractibility of myofibroblast,secreting many cytokines,which contribute to the damage of the alveolar epithelial cells.

肌成纤维细胞在PF的病理进程中扮演着重要的角色，其胶原合成能力强可造成细胞外基质的异常沉积、具收缩性使肺顺应性下降、分泌多种炎性介质加重肺泡上皮损伤。

The positive expression of Slit2 located in the cytoplast on oligodendrocyte and astrocyte.The positive cells were found at 3d after spinal cord injury, reached peak on 7d after injury, declining after 14d. The change of Slit2 was correlative with the rehabilitation and regeneration of the axon on the forepart period.

免疫组织化学检测：Slit2蛋白定位于星型胶质细胞和少突胶质细胞的胞浆，呈棕黄色染色，于脊髓损伤后第3 d出现，阳性细胞逐渐增多，于脊髓损伤后第7 d，Slit2阳性表达的细胞数达到高峰并趋于稳定，伤后第14 d开始逐渐下降，呈一过性增高。

In this study, for the complicated distribution of dose rate in time and space, considering the repair of the sub-death cells, the radionuclide decay law and exponential proliferation of clonogenic cells, the dose-response relationship is built based on the known linear-quadratic model, and the concept of tumor control probability is introduced into the therapy method. Furthermore, the concepts about "curable stage" and "critical time point" and the methods calculating the amount of radionuclide injected into tumor in clinical are proposed.

本课题针对这一方法中靶区复杂的剂量率时-空分布特点，以公认的"线性-二次模型"理论为基础，同时考虑亚致死性细胞修复、核素衰变规律和克隆原性细胞指数增殖，建立了适合这一治疗方法的具有时-空分布特点的剂量效应关系，并进一步将肿瘤控制概率的概念引入这一方法中，提出了"治愈期"及"临界时间点"的概念以及由此指导临床确定药物注射剂量的方法。

The fermentative yield of fructose 1, 6 diphosphate with activated culture method reached 40 mg/mL.
