A BASIC program was written to analyse the data from radioreceptor assay by microcomputer. Concentrations of ligand, total binding, nonspecific binding, specific binding and the ratio of specific binding (number of receptor sites) to free ligand content were calculated for each point. The receptor binding affinity constant and binding capacity were obtained by Sca-tchard analysis. Results and graphs can be displayed on the screen and/ or printed out by using a graphic printer

mRNA in ARE and GW9662 group were 2.276 ±0.534 and 0.362 ±0.026,respectively.Compared with control group,PPARγmRNA level in both of ARE and GW9662 group reached statistical significance (t =4.785,P =0.001 ;t =2.395,P =0.044).PPARγprotein expression in ARE group,GW9662 +ARE group and control group were 27 688.33 ±3 593.06,21 816.00 ±1 644.07,17 716.33 ±2 273.95,respectively,which was higher in ARE group than that in control and GW+ARE group (t =5.159,P =0.001 ;t =3.038,P =0.016). NF-κB p65 mRNA expression in GW9662 +ARE group was 0.346 ±0.149,which in ARE group and GW9662 group were 0.392 ±0.1 87 and 1 .720 ±0.338,respec-tively.The differences of NF-κB p65 mRNA expression level between ARE,and control or GW9662 group were statistically significant (t =3.592,P =0.007;t =7.851 ,P =0.000).While,the differences of Caspase-3 mRNA and protein expression levels among the four groups were not statistically significant (F =1 .1 81 ,P =0.376;F =0.647,P >0.05).Conclusion ARE may restrain NF-κB through up-regulating PPARγto inhibit the proliferation and invasive potential of LLC in vitro, which suggests that PPAR-γmay be a novel therapeutic target for lung cancer.

Objective To improve the quality of aiye processed products, an eucalyptol content in commercially available aiye two processed products of chao aiye and aiye tan was investigated.Methods A capillary gas chromatography was used.The sample was prepared with n-hexane by reflux condensation.Chromatographic conditions: The separation was carried on an Ailgent DB-1 capillary column(30 mm ×0.320 mm ×0.25 μm). Inlet temperature was 200℃ and FID temperature was 250℃.The programmed column temperature was set as follows:maintained at 100℃ for 6 min and raised to 160℃ at the rate of 20℃/min followed by holding for 3min.The splitting-ratio was 5.0:1.The carried gas was nitrogen, flow rate was 1.0 mL/min.Injection volume was 1μL.Results In the given chromatographic conditions, the eucalyptol chromatographic separation had good, and the separation degree was greater than 1.5 between eucalyptol and other impurity peak.The linear range of eucalyptol was 11.4-114.0 mg/mL(r=0.999 5). Methods repeatability and recovery were good.The minimum limit of quantification was 0.5μg/mL.The results of determination of eucalyptol show that the eucalyptol content in the commercially available 11 batch of chao aiye was between 5.6-78.2 μg /g, and 12 batch of aiye tan had no eucalyptol. Conclusion The processing technology of current commercially available aiye processed products of chao aiye and aiye tan need to be improved, and the quality standard need to be improved.
