The signal transduction system induced by epidermal growth factor receptor(EGFR) regulates cell cycle ,modulates cell growth and differentiation and improves damage repair.The overexpression of EGFR in several epithelial tumors including non small cell lung cancer(NSCLC) forecasts low survival rate, poor prognosis and metastasis. Thereby EGFR can be a potential target for gene therapy. Tyrosine kinase inhibitors(TKIs) selectively inhibit tyrosine kinase activity,supress tumor growth ,and increase the sensitivity of radio chemotherapy. [

Objective To explore the diagnosis for early stage lung cancer with "normal" plain CT scan in order to draw the concern of physician to these patients. Methods We reviewed and analyzed 3 cases of central bronchogenic carcinoma with normal plain CT scan at first visit who were confirmed through fiber bronchoscope examination and PET/CT scan later. Then we compared the values of some diagnostic methods for early-stage central bronchogenic carcinoma. Results Three patients were all males with long smoking history. They came to hospital for cough and bloody sputum. All their plain CT scan showed "no abnormal findings", but their symptom continued. Later, the fiber bronchoscope examination and PET/CT scan strongly suggested that they were suffered from central bronchogenic carcinoma, and then the pathological findings and sputum cytology confirmed the diagnosis. Two patients received lobectomy, and the other one was suggested to accept radiotherapy because of his poor lung function. Conclusions The positive rate of plain CT scan for early-stage central bronchogenic carcinoma is relatively low. Thus, some of these patients lost the chance of surgery and combined therapy. So physicians should pay more attention to these patients with symptoms of persistent bloody sputum or obstructive pneumonia, even if the plain CT scan is negative at first visit. Using PET/CT and fiber bronchoscope examination, physicians can confirm the diagnosis of central bronchogenic carcinoma. So these two methods are important in the diagnosis for early-stage central bronchogenic carcinoma without any abnormal plain CT scan findings.

Purpose: To explore the relationship between the effect of docetaxel inducing apoptosis of non-small-cell lung cancer cell and intracellular level of reactive oxygen. Methods: SPC-AI lung cancer cells were treated with 10 -8mol/L docetaxel for 24 hours to observe the apoptotic morphological change under the electromicroscope and fluorescence microscope in ritro. The treated cells were harvested to analyze the cell cycles using flow cytometry and to estimate the intracellular reactive oxygen levels by staining with 2', 7-dichlorodihydrofluorescein diacetate and dihydroethidine. Results: After SPC-AI lung cancer cells were exposed to 10 ~ mol/L docetaxel for 24 hours, the typical apoptotic morphological changes were observed under the electromicroscope and fluorescence microscope. There was a higher reactive oxygen level in docetaxe-treated cells group than in control group. After 24 hours docetaxel exposure, there was a significant G2 ~'M phase arrest of SPC-AI lung cancer cells. Conclusions: Docetaxel can induce apoptosis in SPC-AI lung cancer cells through the mechanism of G2 ~ M phase arrest and by elevating intracellular level of reactive oxygen.

Background and purpose:The epidermal growth factor receptor (EGFR) is commonly overexpressed in a variety of solid tumors, and has important roles in cancer pathogenesis and progression. EGFR thus provides a rational target for cancer therapy. We studied siRNA-mediated inhibition of epidermal growth factor receptor expression and its biologic effects in different human cancer cell lines (A431, HeLa and SPC-A-1). Methods:Cells were transfected with chemically synthesized siRNA-EGFR. EGFR mRNA was quantified by real-time PCR and was detected by immunofluorescence staining and flow cytometry. The biologic effects on cell growth were assessed by colony-formation assay.Results:siRNA-EGFR significantly decreased mRNA level of EGFR by 73.9 %, 44.6 % and 57.7 %, protein expression of EGFR by 77.0 %, 61.3 % and 65.2 %, and reduced colony number by 27.2 %, 53.9 % and 59.1 % in A431, HeLa and SPC-A-1, respectively.Conclusions:Our data suggested that RNA interference could downregulate EGFR and inhibit colony forming ability and EGFR expression at mRNA/protein levels in human cancer cell lines with different pathological types. siRNA could be one of the promising strategies in future targeted cancer therapy.

Objective To investigate the effect of aquaporin 5(AQP5)gene to the differentiation and development of bone marrow-deriued dendritic cells(BMDC).Methotis The DCs obtained from the bone marrow of the AQP5-/- and the wild type(WT)mice were cultured and induced to maturation by LPS.The phenotype of the two types DCs were assayed by FACS,and the phagocytosis ability Was assayed by co-incubating with FITC-conjucted ovalbumin.Results Contrast to the DCs from the WT mice,the DCs from the A9P5-/-mice showed reducing positive rate of expression of the co-stimulating molecular such as CD40,CD80.CD86.And the phagoeytosis ability of DCs from the AOP5-/-mice was lower than that of the WT mice.The relationship of the phagncytosis rate to the time from the AOP5-/- mice was different from that of the WT mice.The stimulating ability of the AOP5-/-DCs was lower than that of the WT mice.Conclusion Water transmembrane moving mediated by AQP5 iS very important to the normal function of DCs.The certain mechanism of the signal moleeular is to be determined.
