Objective To investigate the expression of CD4+CDhi25CDlow127 regulatory T cells (Treg cell), IL-2, IL-10 and IFN-γin peripheral blood of patients with different TNM stages of non-small cell lung cancer( NSCLC) , and to evaluate their correlation. Methods The proportion of CD4+CDhi25 CDlow127 Treg cells to CD4+cell in peripheral blood of 55 NSCLC patients were determined by flow cytometry, and levels of IL-2, IL-10 and IFN-γ were measured by ELISA. The proportion of CD4+CDhi25 CDlow127 Treg cells, IL-2, IL-10 and IFN-γ of patients with different TNM stages of NSCLC were compared, and correlation analysis was carried on. Results The proportion of CD4+CDhi25 CDlow127 Treg cells increased obviously together with the increasing of TNM stages of NSCLC(P<0. 05),so did the level of IL-10 (P<0. 05). On the other hand, the level of IL-2 and IFN-γdecreased apparently with the increasing of TNM sta-ges of NSCLC(P<0. 05). CD4+CDhi25CDlow127Treg cells and IL-10 were positively correlated(P <0. 05). IL-2 and IFN-γ were positively correlated too(P<0. 05). CD4+CDhi25CDlow127Treg cells and IL-10 were all negatively correlated with IL-2 and IFN-γ(P<0. 05). Conclusion The increasing of CD4+ CDhi25CDlow127Treg cells and IL-10 and the de-creasing of IL-2 and IFN-γ are possibly one of the reasons of antitumor immunity suppression in terminal NSCLC patients. The surveillance for them can be reference indicators to evaluate antitumor immunity status of terminal lung cancer patients.

Abstract? AlM: To investigate the inhibition effect of bevacizumab on human Tenon capsule fibroblasts ( HTFs ) and discuss the countermeasures of bleb scarringscarring in glaucoma surgery countermeasures.? METHODS: Adopted cell recovery method and followed the aseptic principles, we performed the culture of HTFs which came from the Central Laboratory of Shaanxi People's Hospital cell library. Wound Healing assay:We scraped a cell-free zone on the cell surface when the cells reached confluence at 80%. The control group was added to serum-free DMEM medium. The HTFs of bevacizumab group were stimulated with 1mg/mL concentrations without DEME for 0, 24, 48, and 72h. The scratch width was observed and measured.? RESULTS: HTFs were long fusiform shape under microscope, the nucleus is in the center of the cell with larger nucleus, abundant cytoplasm, were arranged in a whorled growth out of shape, strong ability to proliferate, conform to general forms of fibroblast. The morphological and biological characteristics of cells after cryopreservation and resuscitation remain unchanged. Wound healing assay: 0h, equal to the initial width of the two groups, 24h when the migration distance of the two groups of cells are basically the same, 48h when the control group cell migration distance is greater than that in the bevacizumab processing group, 72h when the control group scratches basichealing, bevacizumab treated cells migrate closer than 48h no significant change, and a lot of cells died.?CONCLUSlON:Cell recovery method can successfully cultured HTFs, which was stability on morphology and biological properties, laying the cellular basis for experimental research. Fibroblast itself has a strong ability to migrate, outside - derived bevacizumab can inhibit HTFs migration evidently and it will cause excessive cell death when. Bevacizumab has certain extent inhibitory effect on HTFs migration, and it is likely to become one of the important drugs for creating bleb scarring after glaucoma surgery in the future.

Background Scarring of filtration channel following glaucoma filtering surgery is a main cause of the failure of the surgery.The proliferation,epithelial-mesenchymal transition and extracellular matrix remodeling of fibroblasts are thought to be the primary pathological mechanism of scarring.Connective tissue growth factor (CTGF) plays a promoting role in the formation of scar.Whether CTGF participates in mesenchymal-epithelial transition of human Tenon capsule fibroblasts (HTFs) is not clear yet.Objective This study attempted to investigate the effect of CTGF on the mesenchymal-epithelial transition of HTFs in vitro.Methods HTFs were cultured and passaged in high glucose DMEM medium with 10％ fetal bovine serum,and the cells of generation 3-6 were used in this experiment.The cells were divided into the blank control group and CTGF-treated group and were routinely cultured in the blank control group.CTGF was added in the medium in the CTGF-treated group,with the final concentration 50 ng/ml CTGF.Immunofluorescence staining was used to identify and locate the expression of E-cadherin protein in the cells,and Western blot assay was employed to quantitatively analyze the expression level of E-cadherin protein in 48 hours after culture.Results The HTFs grew well with the spindle-like shape and vortex-like arrangement.The red fluorescence (E-cadherin protein) in the cytoplasm and blue fluorescence in the cellular nucleus were seen in the CTGF-treated group,but only nucleus with blue fluorescence were obtained in the blank control group.Western blot assay showed that the E-cadherin protein expression was absent in the blank control group,however,the relative expression level of E-cadherin protein in the cells was 0.63± 0.08.Conclusions E-cadherin protein is not expressed in fibroblast derived from mesenchymal tissue.However,CTGF can induce the expression of E-cadherin in HTFs.This study suggests that CTGF promotes the mesenchymal-epithelial transition of HTFs in vitro.

ⅡB. Our investigation also showed that the activity of PAS, LDH and PFK was stronger in type Ⅱ fibers than in type Ⅰ. It was concluded that each type fibers in the rat plantaris exhibit significant differences in metabolic and functional activity. The type ⅡA fibers present both high activity of glycolytie enzyme and oxidase, and reflect that these enzymes may play very important role in energy metabolism. Further study remains to bedertaken.

Objective To study the relationship between the inhibitory effects that myelin membrane proteins exerted on nerve regeneration and the changes of intracellular cAMP levels in neurons. Methods To observe the effects of myelin membrane proteins extracted from central nervous system(CNS) by density centrifugation on the outgrowth of neurite of cerebella granule cells in culture and detect the changes of intracellular cAMP levels of the neurons with radioimmunoassay. Results 1\^Myelin membrane proteins of CNS inhibited neurite outgrowth of cultured cerebella granule cells. 2\^The cAMP level in neurons decreased in 5 minutes after contacting myelin membrane proteins and reached to the lowest level in 12 hours of contacting. Conclusion The inhibitory effects of myelin membrane proteins on the outgrowth of neurites may be related to the inhibitory factors which cause the decrease of cAMP level in neuron through the passway of signal transduction pathway.
