The results showed that the method of rubbing the kerf then injection of retrovirus suspension into pancreas could more effectively mark the pancreatic cells than the caudal vein injection and the intraperitoneal injection did in vivo. Furthermore, this study also found that some acinus cells could accept injury stimulus signals to regenerate through resuming mitosis after pancreatic injury.

结果发现在活体条件下，与尾静脉注射及腹腔注射法相比，胰腺伤口涂抹并胰腺内注射反转录病毒的方法能够更有效的标记胰腺细胞；而且，通过对标记细胞的世系追踪研究证明，在胰腺损伤后，胰腺腺泡细胞能够接受损伤信号刺激发生再生。

Aim:To observe the amitosis and asymmetric division in subcultured PC12 cells, and to explore the role of amitosis and asymmetric division in tumorigenesis, tumor cell pleomorphism and differentiation.

目的 ：观察传代培养的PC12细胞的无丝分裂和不对称分裂，探讨其在肿瘤发生、肿瘤细胞多形性和细胞分化中的意义。

Amitosis and asymmetric division play an important role in PC12 cell pleomorphism. The asymmetric division possesses important significance in tumorigenesis and differentiation.

无丝分裂和不对称分裂是PC12细胞多形性形成的主要原因，肿瘤细胞无丝分裂及其不对称性对肿瘤发生及肿瘤细胞的分化具有重要意义。

Investigation of formation, proliferation and degradation of the peroxisome is an important part of study of organelles biogenesis.

过氧化物酶体（peroxisome，P）是真核细胞中普遍存在的细胞器，参与多种重要的代谢过程。P的产生、增殖及降解是细胞器发生机理研究的重要部分。

Due to the advancement in experimental methods including genic and biochemical technology, the mechanisms of the genesis and development of myopia have been widely studied. In this paper we focus on the genetic, cellular and molecular mechanisms in the development of myopia.

近视的发生与多种因素相关，本文对近视发生机制发生的遗传和环境两方面因素进行综述，重点讨论了遗传学和生化技术对近视发生发展的基因水平、细胞水平和分子水平机制的研究进展。

It has beenconfirmed that the occurrence of basal cell carcinoma, small cell lung cancer,pancreatic cancer, prickle cell carcinoma, prostatic carcinoma, carcinoma of bladder,medulloblastoma and gastric cancer of mankind have a close relationship with the abnormal activation of Sonic hedgehog signaling pathway.

现已证实人类皮肤基底细胞癌、小细胞肺癌、胰腺癌、口腔鳞状细胞癌、前列腺癌、膀胱癌、髓母细胞瘤、胃癌等肿瘤的发生与sonic hedgehog信号通路异常激活密切相关。

Four weeks later, in the baicalin group, some spindle-shaped UCB-MSCs began to present shrinkage, with slender processes on the cell edge, and some UCB-MSCs tended to be spherical-, conical-, and triangle-shaped appearance, with many slender processes on the pseudopodia.

细胞形态学观察：脐血单个核细胞培养第2~3天开始贴壁生长，2周左右达高峰，3周后细胞生长达80%~90%融合，此时脐血原始间充质干细胞呈较均一的长梭形。4周后，黄芩苷组原来呈梭形的胞体一部分发生收缩，细胞边缘出现细的突起；一部分胞体逐渐近似圆形、锥形、三角形，伪足有多个细长突起。

Comparison of different types of stem cutting in rooting induced and analysis the cDNA clones which may be associated with the occurrence of adventitious roots of P.euphratica,the model of ARF were initial establishment of exogenous IBA controlling endogenous IAA occurred threshold and equilibrium,that is,exogenous IBA receiving by receptor of stem cutting,and transfer into the cells,then turn into active IAA by the effects of the POD enzyme.

通过对胡杨3个不定根发生调控培养体系的比较和与胡杨不定根发生可能相关的差异基因的克隆分析，初步建立IBA调控胡杨不定根发生的内源IAA阈值和激素间平衡的模型，即外源IBA通过插穗受体接收，转入细胞内并在POD酶作用下转化成具有活性的IAA，当IAA的水甲在促根的阈值内并保持相对平稳时，则有利于生根；当IAA的浓度增高超过阈值且不稳定时，则抑制不定根的发生。

There prominent suppression of cellular immunity in secondary syphilis patients is observed and the change of T-lymphocyte subsets and NK cells were closely with the pathogenic mechanism of syphilis.

我们应用流式细胞仪对Ⅱ期梅毒患者外周血T淋巴细胞亚群、NK细胞、B细胞进行检测并与正常组对照，了解梅毒患者的细胞免疫功能状态，探讨其在梅毒的发生、发展中的作用及意义。

Results The hair-cell-like cells with tufts of microvilli were found on their surface in the damaged organ of Corti at 7 days after stopping of injection.

结果 在外毛细胞损伤区有细胞表面长有微绒毛簇的毛细胞样细胞出现，且其在损伤Croti器中有发生-发展-退化的变化过程。
