Objective To observe the clinical efficacy of Qingjinchangfei drink for treating AECOPD.Methods We Used random number table to separate 84 patients in to two groups:treatment group and control group.The treatment group used western medicine conventional treatment and Chinese medicine decoction Qingjinchangfei drink.The control group used western medicine conventional treatment.Both two groups were 14 days treatment.We recorded the improvement of symptoms and signs everyday.We compared the lung function,inflammatory cytokines,such as IL-8、IL-2 before and after treatment in the two groups.Results The total efficient in treatment group was obviously better than that in control group.The indicators such as clinical symptoms,signs,pulmonary function indicators were obviously better than that in control group.Compared with before treatment,IL-8,ET,MDA and TNF-? in sputum and blood were obviously lower but IL-2 was obviously higher.Conclusion Qingjinchangfei drink plus western medicine conventional treatment for treating AECOPD was obviously better than western medicine conventional treatment.

Objective To explore the relationship between the expression of XRCC1 and glioma. Methods Total of 26 samples of glioma were divided into 4 groups:gradeⅠ,gradeⅡ,gradeⅢand gradeⅣ. The expression of XRCC1 in 26 Gliomas tissues were examined using SP immunohistochemical staining.Results The positive staining of XRCC1 protein was localized in nucleus of tumor cells in Glioma. There was no correlation among them. The difference of XRCC1 expression among gradeⅠ~Ⅳ was not significant ( >0.05) .Conclusion The difference of XRCC1 expression among gradeⅠ~Ⅳ was not significant. The expression of XRCC1 was closely correlated with the effect of radiotherapy.

Objective To investigate the molecular mechanism of retinoic acid in targeted treatment of craniopharyngioma by detecting the expression of RARαand PPARβ/δin craniopharyngioma cells and analyzing the correlation between the expression and effect of retinoic acid. Methods The expression of RARα and PPARβ/δ in craniopharyngioma cells from 31 patients cultured in vitro was quantified by reverse transcription-PCR. The inhibition rates of RA on craniopharyngioma with different expression of RARα and PPARβ/δ were detected by using MTT assay, and the correlation between the expression of RARα and PPARβ/δand the effect of RA was analyzed. Results 1. The RT-PCR results showed that the expression levels of PPARβ/δand RARα mRNA were different. Craniopharyngioma cells from 31 patients in primary culture were divided into three groups according the expression levels of nuclear receptor: PPARβ/δ>RARα group, RARα>PPARβ/δ group and RARα>>PPARβ/δ group. 2.MTT results showed that the inhibition rate of RARα>>PPARβ/δgroup was significantly higher than the other groups under same drug, the differences had statistical significance ( <0.01) . Conclusions The expression of PPARβ/δ, RARα can be used to evaluate the effect of RA in treatment of craniopharyngioma. The craniopharyngioma with low-expression of PPARβ/δ is more sensitive to RA. Targeting higher RARα or targeting lower PPARβ/δ is beneficial to the treatment of craniopharyngiomas.
