RESULTS: hADSCs presented fibroblast-like morphological feature with a flocked array. The 3rd passage of hADSCs had unique immunophenotypes and they were positive for CD73, CD44, CD166, CD105 and CD29, but negative for CD31, CD34, CD45 and HLA-DR. Cell cycle result showed that they had the typical growth characteristics of stem cells, namely, 83.81% cells stayed at G0/G1 stage, only 16.19% cells were stayed at S+G2/M stage; The latent phase of the primary culture cells was 2 days prior to and after incubation, followed by 3-6 days of logarithmical proliferation, reached a peak at day 6, and entering the growth platform phase with lower growth speed.

结果：分离培养的人脂肪间充质干细胞为成纤维细胞样，呈漩涡状排列。P3代人脂肪间充质干细胞呈CD73，CD105，CD166，CD44及CD29阳性，而CD31，CD34，CD45及HLA-DR阴性；具有典型的干细胞增殖特点，83.81%细胞处于G0/G1期，仅16.19%细胞处于S+G2/M期；细胞在接种后前2 d处于生长潜伏期，第3~6天处于对数生长期，第6天达峰值，以后细胞生长速度减慢，进入生长平台期，平均五六天传代1次。

The therapeutic mechanism of the method of nourishing qi, activating blood, dispersing phlegm and promoting the collaterals was supposed as that it intervened the airway remodeling and alleviated the progress of airflow obstruction of COPD by suppressing the chemo taxis of cytokines, regulating the proliferation of fibroblast cell and smooth muscle cell and preventing the proliferation and plerosis of extracellular matrix.

推测益气活血化痰通络法防治COPD的机制可能为：通过抑制炎症细胞的趋化、影响细胞因子的活性、调节成纤维细胞和平滑肌细胞的增殖、阻止细胞外基质的增生修复，从而达到干预COPD患者气道结构重塑，减缓COPD气流受限进展的作用。

Finally, we established rat model of PF induced by bleomycetin, and observed the interventional action of phenol total base to model. The analysis of experimental result including pathematologic and tissue biochemical indicator showed phenol total base of plumula nelumbinis have some therapeutic action to rat model of PF induced by BLM.

通过病理学观测及组织生化指标的检测(SOD、MAD、GSH一PX、Hyp)，说明莲子心酚性总碱对博莱霉素致大鼠肺纤维化有一定治疗作用，可能的作用机制：降低肺纤维时胶原含量；抑制肺成纤维细胞的增殖；抗自由基和抗脂质过氧化作用及提高了机体内GSH一Px含量。

The mechanism of action maybe include the depression in content of collagen, inhibition to proliferation of lung fibroblast, action of anti free redical and anti lipid peroxidation, and elevation of content of GSH-PX.So we think phenol total base of plumula nelumbinis is a sort of promising drug to healing PF.

综上所述，我们认为莲子心酚性总碱可能对肺纤维化的病理过程有多靶点作用：前期通过抗自由基作用，从而减轻肺泡炎损伤：后期直接抑制肺成纤维细胞的增殖及蛋白沉积，减轻纤维化病变程度。

After renal cortexes were Grinded and digested with 0.25%tryspase.The cell types of epithelial cell were identified by immunocytochemistry.The injury model of rats, renal tubular epithelial cells were established by using gentamicin.And observed the role of bFGF in renal tubular epithelial cell.

通过对大鼠肾皮质研磨、过网的方法，并以0.25%胰蛋白酶消化，以免疫细胞化学方法鉴定体外培养的肾小管上皮细胞(抗Cytokeratin 18抗体)，以庆大霉素对培养的肾小管上皮细胞建立损害作用模型，然后观察碱性成纤维细胞生长因子对损害的肾小管上皮细胞的保护作用。

CD34+ cells were harvested from G-CSF mobilized adult blood and umbilical cord blood and incubated onto fibronectin/gelatin-coated Petric dishes in the presence of recombinant human vascular endothelial cell growth factorand basic fibroblast growth factor.

毛宁为证明出生后血液循环中存在内皮细胞的前体细胞，从G-CSF动员的成人外周血及脐带血中分离CD34+细胞，将之接种于纤连蛋白与明胶铺板的培养皿上，培养体系中加入重组人内皮细胞生长因子和重组人碱性成纤维细胞生长因子。

Specific inhibition of Hh signalling using small molecule inhibitors, a neutralizing anti-Hh antibody or genetic deletion of smoothened in the mouse stroma results in growth inhibition in xenograft tumour models.

由癌细胞分泌的Hedgehog配体，在肿瘤表皮细胞中未能激活信号作用，而是在&基质&上发挥作用（&基质&由细胞外基质、成纤维细胞、内皮细胞和微血管组成，恶性细胞着床于其中）。

The methods of sticking tissues piece to culture primary hFCECs and mouse 3T3 fibroblast conditioned medium to culture passage hFCECs were established;2.The Proliferative capacity of corneal limbus hFCECs is better than central hFCECs.3.3T3 conditioned medium could markedly promote the proliferation of epithelial cells

结论一、组织块贴壁法原代培养人胎儿角膜上皮细胞以及小鼠3T3成纤维细胞条件培养液传代培养方法基本建立；二、人胎儿角膜缘部上皮细胞增殖能力优于中央部；三、3T3细胞条件培养液能促进角膜上皮细胞的增殖。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
