Methods CD34(superscript +) cells and AC133(superscript +) cells were gathered by MiniMACS, then the cell factors were divided into 6 groups. Through the ex vivo comparison cultivation under different cell factor combination stimulation, expansion of the CD34(superscript +) and AC133(superscript +) selection cells was observed and the clone formation of the CD34(superscript +) and AC133(superscript +) cells was also observed by using Half-solid Methyl cellulose under different cell factor stimulation (during 7d, 14d, 21d.). The rate of cell apoptosis was determined.

There is not a significant difference in these groups by one-way analysis of variance. 2 Among 51 cases with lung cancer, 7 specimens showed malignant cells in bronchial lavages, including 4 cases in central lung cancer and 3 cases in peripheral lung cancer. Concordant results were observed in 20 cases. 6 specimens showed malignant cells on cytological analysis, and NMSP was positive in at least one gene tested. 14 samples did not show malignant cells on cytological analysis, and the NMSP results were correspondingly negative. The results of cytology and NMSP were discordant in 31 samples. 30 samples were cytologically negative, but NMSP positive in one or more genes. In addition, there was one case that the cytology was positive for malignant cells, but the NMSP was negative in all of the three gene tested.

At the same time, the process of the wound healing was observed histologically, and the regeneration cycle of epidermal cells and the temporal change in inflammatory cells were measured. Results Inflammatory cells infiltrated into wound surface were neutrophils, followed by macrophages and lastly lymphocytes. Epidermal cells proliferated most actively on PBD 3 and the mitoses of them increased significantly on day 7 after burn. The gene expression of PDGF, PDGFR and EGFR reached peaks on PBD 1 and the gene expression of EGF and TGFβ-R2 were highest on PBD 3. In addition, the gene expression of TGFβ-R1 and TGFβ1 increased significantly on PBDs 5 and 7 respectively.

结果 炎性细胞到达创面依次为中性粒细胞、巨噬细胞和淋巴细胞；表皮细胞周期变化为伤后3天细胞增殖活跃，伤后7天细胞分裂明显增多；伤后1，3天PDGF、PDGFR(血小板源性生长因子受体)和EGFR基因表达明显增强，伤后3，5天EGF、TGFβ-R2基因表达增强，伤后5，7天TGFβ-R1(转化生长因子β受体1)基因表达增强，伤后7，10天TGFβ1基因表达增强。

Objective:The aim of the experiment is to search for the regulation that the hepatic stem cells abnormally differentiate into cancer cells. In the experiment,the variating regulation of PCNA,c-kit and c-myc in the formation and development of HCC will be interpreted with immunohistochemistry and RT-PCR. So,the initial mechanism that hepatic stem cells abnormally differentiate into cancer cells from the levels of cell,protein and gene will be clarified. The last,the inhibition to HCC with ulinastain will be studied,from which,a new way of clinical prevention and treatment for HCC will expect to be explored.

二、目的本实验旨在探讨以卵圆细胞为代表的肝干细胞在HCC发生、发展过程中在肝组织内分布规律，并通过免疫组化、RT-PCR等技术阐明PCNA、c-kit、c-myc在HCC发生、发展过程中的动态演变规律，从细胞、蛋白、基因三个水平初步研究卵圆细胞向癌细胞异常分化的机制，同时观察乌司他丁对HCC发生、发展的抑制作用，为肝癌的临床预防和治疗探索新的途径。

By incorporation of tritiated thymidine or 5-bromodeoxyuridine and using them as the markers, we found that the basal cells, Clara cells and type II alveolar epithelial cells in the pulmonary tissues may in some way behave like stem cells and can eventually differentiate into respiratory tract epithelium.

The result showed that the surface architecture and ultrastructure of I.punctatus ' gill and secondary gill lamellae were similar to those of other teleosts. The surface of gill arches and gill rakers was covered with pavement cells which were characterized by circular microridges, and secreting-holes were found among cells on the surface of gill arches. The base part of gill rakers were bigger in terms of diameter. The pavement cells' surface of gill filaments' middle part was characterized by microridges with fine lateral protuberances on both sides which were either fused or interruped, while the microridges disappeared on the pavement cells' surface on both top and base parts of gill filaments, forming dense granulated protuberances. The height and interlamellar space of secondary gill lamellae in I.punctatus were relatively higher and bigger, respectively.
