OBJECTIVE: To explore the effects of Houttuynia Cordata on expression of human beta-defensin-2 (HBD-2) in pulmonary epithelial cells (SPC-A-1) in vitro; and to observe the correlationship between the level of HBD-2 mRNA and the concentrations or treatment times of Houttuynia Cordata. METHODS: The SPC-A-1 cells were cultured with different concentrations of Houttuynia Cordata in vitro, including 0, 12.5, 25, 50, 100 and 200 microg/ml. And then, the SPC-A-1 cells were cultured with the optimal concentration of Houttuynia Cordata in different lengths of time, including 1, 2, 4, 8, 16 and 24 hours. After the treatment, the mRNA level of HBD-2 in pulmonary epithelial cells was detected by means of semi-quantitative reverse transcription polymerase chain reaction (RT-PCR). RESULTS: After being cultured with Houttuynia Cordata, the expression of HBD-2 mRNA had positive correlation with the stimulus concentrations (rs=0.829, P=0.042) and stimulus time (rs=0.914, P=0.003). The highest expression of HBD-2 mRNA was induced by 100 microg/ml Houttuynia Cordata after 8-hour treatment. In comparison with the normal control group and the interleukin-1beta group, 100 microg/ml Houttuynia Cordata could significantly up-regulate the expression of HBD-2 mRNA in SPC-A-1 cells after 8-hour treatment (P<0.01). CONCLUSION: Houttuynia Cordata can up-regulate expression of HBD-2 mRNA in SPC-A-1 cells, and the highest expression level of HBD-2 mRNA can be obtained by culture with 100 microg/ml Houttuynia Cordata for 8 hours.

Aim To explore the effect of connexin 43 ( Cx 4 3 ) on acquired gefitinib-resistance in human non small cell lung cancer ( NSCLC ) . Methods HCC827 GR, a gefitinib-resistant ( GR) NSCLC cell lines from their parental cells was established by gradually in-creasing the concentration of gefitinib. Gefitinib effica-cy in HCC827 and HCC827 GR cells was detected by MTT assay. Expression of Cx43 mRNA in HCC827 and HCC827 GR cells was determined by RT-PCR. The protein expressions of Cx43 and phospho-Akt ( p-Akt) in these cells were detected by Western blot. The func-tional gap junction intercellular communication ( GJIC ) was measured by parachute assay. The cellular locali-zation of Cx43 protein was evaluated by immunofluores-cence staining. Results MTT assay showed less ge-fitinib cytotoxicity in HCC827 GR cells than that in their parental cells with IC50 of (10. 84 ± 0. 021) μmol ·L-1 versus (0. 07 ± 0. 019) μmol·L-1 , respective-ly. Moreover, both mRNA and protein expressions of Cx43 in HCC827 GR cells were significantly lower than those in HCC827 cells ( P<0. 05 ) . However, the p-Akt protein in HCC827 GR cells was obviously higher than that in HCC827 cells ( P<0. 05 ) . Furthermore, treatment with LY294002 caused a significant reduced p-Akt expression, but a significant increased Cx43 ex-pression in HCC827 GR cells. Moreover, no detecta-ble GJIC was found in HCC827 and their GR cells with or without RA ( a well-defined GJIC enhancer ) treat-ment. Immunofluorescence staining clearly showed that Cx43 protein accumulated in the cytoplasm of HCC827 and their GR cells. Conclusion The down-regulation of Cx43 expression in cytoplasm of HCC827 GR cells may contribute to the acquired gefitinib resistance in NSCLC cells by GJIC-independent activation of PI3 K/Akt signaling pathway.

OBJECTIVE:To study the preventive effect of Lonicera japonica alcohol extract on mice with liver injury based on metabolomics method. METHODS:30 mice were equally randomized into a normal control (isometric normal saline) group,a model(isometric normal saline)group and a group of L. japonica alcohol extract(2 g/kg). The mice were given drugs by ig once a day for 14 consecutive days. On the 8th day of administration,the models were established by giving 0.2% dimethyl sulfoxide (DMN,10 ml/kg)ip once a day for 7 consecutive days. Gas chromatography-mass spectrum(GC-MS)was used to analyze 24 h total ions chromatogram of the urine sample on the 1st,3rd,5th and 7th day of administration of drugs and DMN. The change in endogenic small molecule metabolites in urine was observed. Principal component analysis was employed to explore the change in the metabolite chromatogram and underlying biomarkers in urine. RESULTS:The contour of the chromatogram changed to a largest extent 1 to 5 d after given DMN,but showed an obvious trend towards regression 7 days thereafter. DMN resulted in increase in the contents of 8-phenyl-8-azbicyclo-[4,3,0]non-3-ene-7,9-dione,2-(6-heptynyl)-1,3 dioxolane,bis-(O-methyloxime)-4-ketoglu-cose,and decrease in the contents of malonic acid,2-(4- chlorophenylthiomethoxyl)ethyl,tetrahydro-2-furanacetaldehyde,D-ga-lactose,erythro-pentonic acid and galacturonic acid,in endogenic small molecule metabolites in mouse urine,for which Lonicera japonica alcohol extract can improve that. CONCLUSIONS:Previous administration of L. japonica alcohol extract ig has preven-tive effect to some extent on the physiological and metabolic conditions of mice with liver injury induced by DMN.
