Objective To investigate the effects of 4.1N expression in lung cancer A549 cell line on cell proliferation, invasion and migration. Methods A549 cells were cultured in vitro and transfected with lipofectamine 2000 mediation. Three groups were employed: transfection with pEGFP-4.1N plasmid, pEGFP vector plasmid, and blank control, respectively. The mRNA and protein expression differences of 4.1N was examined by semi-quantitative RT-PCR and Western blot in every group after 48 h. The proliferation capability was determined by MTT assay. Invasion capability was evaluated by scratches, adhesion experiments and Transwell chamber model. Results After the transfection, the expression of 4.1N mRNA and protein in pEGFP-4.1N plasmid transfection group was significantly enhanced (P<0.05). The proliferation capability of A549 cells descended extremely (P<0.05). The migration and invasion capability of A549 cells in vitro decreased substantially (P<0.05). Conclusions Transfected with 4.1N gene can significantly increases the expression levels of 4.1N mRNA and protein in A549 cells which are highly metastatic in human. Cell behavior in vitro studies showed that 4.1N gene can inhibit the proliferation, adhesion, invasion and migration of A549 cells, which plays an important role in the metastasis of lung cancer and it may become a molecular marker for metastasis of lung cancer.

Objective To evaluate the application value of confocal laser scanning microscopy(CLSM)in the differentiation between seborrheic keratosis and Bowen′s disease. Methods CLSM was used to observe typical skin lesions in 88 patients clinically diagnosed with seborrheic keratosis and 18 patients clinically diagnosed with Bowen′s disease. Then, tissue specimens were resected from these lesions and subjected to histopathological examination. Results CLSM imaging of seborrheic keratosis lesions showed gyrus?like structures and keratin?filled inclusion cysts in the epidermis with trabecula?like extension of rete ridges in all the 88 cases, basal cells arranged in a cordike or radial pattern in 9 cases, and bright reflective structures in the basal layer and dermis in 6 cases. CLSM imaging of Bowen′s disease lesions revealed disorderly arrangement of large, irregularly shaped atypical cells in some areas in the middle and lower epidermis, and infiltration of scattered mononuclear cells in the superficial dermis. Conclusion CLSM images of seborrheic keratosis are different from those of Bowen′s disease, and CLSM may be helpful for their differential diagnosis.

OBJECTIVE Ginsenoside metabolite compound K (CK) is a degradation product of ginsenoside in the intestine by bacteria. The anti-inflammatory and immunomodulatory activities of CK have been reported. This study investigated whether CK exerted its immunoregulatory effect through modulation of dendritic cells (DCs) function. METHODS In vivo, severity of collegen-induced arthritis (CIA), T cells and DCs subsets, phenotype of DC were assayed by flow cytometry, CCL19 and CCL21 level in lymph nodes assayed by ELISA. In vitro, bone marrow-derived DCs from normal mice were matured with lipopolysaccharide and treated with CK for 48 h. In vivo, bone marrow-derived DCs were generated from CIA mice before and 2 weeks into CK treatment. DCs were analyzed for migration, phenotype and T- cell stimulatory capacity. RESULTS CK alleviated the severity of CIA, decreased pDCs and mo-DCs, increased na?ve T cells in CIA mice lymph nodes, and suppressed CCL21 expression in lymph nodes. CK suppressed DCs migration induced by CCL21 and T cells-stimulatory capability of DC, down-regulated LPS-induced expression of CD80, CD86, MHCII and CCR7 on DCs. CONCLUSION This study elucidated the novel immunomodulatory property of CK via impairing function of DCs in priming T cells activation. These results provide an interesting novel insight into the potential mechanism by which CK contribute to the restoration of immunoregulation in autoimmune conditions.
