Objective To explore the effect of chlamydia pneumoniae(CP)infection on T lymphocyte subsets in patients with chronic obstructive pulmonary disease(COPD).Methods A total of 176 patients with acute exacerbations of COPD who were admitted to hospital from Jan.2001 to Jan.2005,and 46 healthy subjects were selected.Chlamydia pneumoniae-specific serum IgG,IgA,IgM antibodies were measured by microimmunofluorescence(MIF)test;the flow cytometer was used to analyze the frequency of CD+_3,CD+_4 and CD+_8 lymphocytes in patients with COPD and controls.Results The rate of acute chlamydia pneumoniae infection in COPD patients with acute exacerbations was 27.3% and that of chronic CP infection was 19.3%.They were all significantly higher than that in healthy subjects(P﹤0.01).The frequency of the CD+_3 and CD+_4 lymphocytes showed no difference in each group.The frequency of CD+_8 lymphocyte in COPD patients of chronic CP infection rose and the CD+_4/CD+_8 ratio was decreased in comparison with controls.On the other hand,the CD+_8 lymphocytes and the CD+_4/CD+_8 ratio showed no difference between chronic CP infection group,no CP infection group and controls.Conclusion The chlamydia pneumoniae infection is a rather frequent event in acute exacerbations of COPD,and it is an important reason to cause the disorder of cell-mediated immunity in COPD patients.The disorder of cell-mediated immunity may be involved in pathogenesis of COPD.

AIM: To identify the key factors responsible for drug resistance in different ovarian cancer cell lines using protein microarray system. METHODS: Six ovarian cancer cell lines were employed. The sensitivity of ovarian cancer cell line to common chemotherapeutic drugs was determined by using MTT assays. The expression of 78 cytokines and other factors was examined by using cytokine antibody array technology. RESULTS: Different ovarian cancer cell line responded to chemotherapeutic agents differently. The drug resistance was correlated with certain cytokine expression. Cell line SKOV3 was less sensitive to first line chemotherapeutic drug (ADM, CBPDA) and accumulated high amounts of GRO and TIMP-2 compared with other 5 cell lines. OVCAR4 cells were more resistant to second line chemotherapeutic drug (TAXOL, VP16) and had higher levers of IL-6 and IL-8 than IGROV1, OVCAR3 and OVCAR5. CONCLUSIONS: Among the most common excretive cytokines, increasing of GRO, IL-6, IL-8 and TIMP-2 might be related to drug-resistance of ADM and CBPDA in ovarian cancer cell, while IL-6 and IL-8 might also be related with drug resistance of TAXOL and VP16. The different types of ovarian cancer cell might have roughly similar excretive cytokines-induced mechanism of drug resistance.

This study examined the differences in tumor formation of three bladder tumor cell lines (BIU-87, T24 and EJ) after subcutaneously transplanted into nude mice, in order to find the best technique for establishing in vivo bladder tumor model. BIU-87, T24 and EJ cells at logarithmic phase were re-suspended in serum-free medium. The cells suspensions of the identical concentration were subcutaneously transplanted into nude mice and then the success rate and tumor growth were compared among the three cell groups. The results of tumor formation were pathologically evaluated. Lung, liver and kidney tissues were also pathologically examined for distant metastasis. The proliferation of the three cells were determined by immunohistochemically detecting the PCNA expression in the tumors. The results showed that the success rates of EJ and T24 cells were significantly higher than that of BIU-87 cells and no distant metastasis was noted among the three groups. The proliferation levels of EJ and T24 cells was significantly higher than that of BIU-87. But at the later stage of tumor formation, as compared with T24 cells, EJ grew more vigorously, soon resulting in the central necrosis of tumor, which affected the measurement of the actual size of the tumors. Moreover, PCNA staining exhibited that the proliferation of EJ and T24 was significantly higher than that of BIU-87 cells. It is concluded that as compared with BIU-87 cells, EJ and T24 cells had higher success rates, with not significant differences in death rate and distant metastasis found among them. There existed no significant difference in tumor formation between EJ and T24 cells and T24 cells do not rupture easily, which makes it a better cell line for the establishment of in vivo bladder tumor model.

Objective To study the effect of Atorvastatin on the level of serum high-sensitivity C-reactive protein(hs-CRP) and nitric oxide(NO) in patients with acute cerebral infartion(ACI). Methods 60 patients with ACI were randomly divided into the Atorvastatin therapy group (n=30) and the conventional therapy group (n=30). At the basic of conventional therapy, the Atorvastatin therapy group was treated with Atorvastatin 20 mg/d. Both groups were treated for 14 consecutive days. The levels of serum hs-CRP and NO were measured and the scores of neurological deficit (NDS) were evaluated before and after treatment. Results The levels of serum hs-CRP in both two groups after 14 d treatment were significantly lower than those before treatment ( all P
