Using high-performance liquid chromatography, we found that dopamine and dopaminergic metabolite（dihydroxyphenylacetic acid and homovanillic acid） content in the midbrain of Parkinson’s disease rats was increased after neural stem cell transplantation ＋ Zhichan decoction, compared with neural stem cell transplantation alone. Our genetic algorithm results show that dihydroxyphenylacetic acid and homovanillic acid levels achieve global optimization. Neural stem cell transplantation ＋ Zhichan decoction increased dihydroxyphenylacetic acid levels up to 10-fold, while transplantation alone resulted in a 3-fold increment. Homovanillic acid levels showed no apparent change. Our experimental findings show that after neural stem cell transplantation in Parkinson’s disease rats, Zhichan decoction can promote differentiation of neural stem cells into dopaminergic neurons.展开更多

文摘目的研究辛前甘桔汤对慢性鼻窦炎(CRS)小鼠长链非编码RNA小核仁RNA宿主基因16(lnc RNA SNHG16)、表皮生长因子受体(EGFR)及黏蛋白5AC(MUC5AC)m RNA表达的影响。方法36只C57BL/6小鼠随机分为正常组、模型组、羧甲司坦组及辛前甘桔汤低、中、高剂量组,每组6只。采用金黄色葡萄球菌鼻腔灌注建立小鼠CRS模型。正常组与模型组小鼠灌胃质量分数为0.9%的氯化钠溶液(0.6 g·kg^(-1)·d^(-1)),辛前甘桔汤低、中、高剂量组分别灌胃辛前甘桔汤水煎液(0.3、0.6、1.2 g·kg^(-1)·d^(-1)),羧甲司坦组灌胃羧甲司坦口服液(0.3 m L·kg^(-1)·d^(-1)),连续干预14 d。采用苏木精-伊红(HE)及阿尔新蓝-过碘酸雪夫(AB-PAS)染色法观察小鼠鼻黏膜结构,免疫组织化学法观察小鼠鼻黏膜EGFR、MUC5AC表达并测量光密度值;酶联免疫吸附试验(ELISA)检测样本中白介素-6(IL-6)、白介素-8(IL-8)、基质金属蛋白酶-9(MMP-9)水平。实时荧光定量逆转录聚合酶链式反应(RT-q PCR)检测样本中lnc RNA SNHG16、EGFR、MUC5AC m RNA的表达。结果与正常组比较,模型组鼻黏膜上皮结构紊乱,IL-6、IL-8、MMP-9含量明显升高(P<0.05),lnc RNA SNHG16、EGFR、MUC5AC m RNA表达明显升高(P<0.05)。与模型组比较,辛前甘桔汤各剂量组IL-6水平显著降低(P<0.05),辛前甘桔汤中、高剂量组MMP-9、IL-8水平降低(P<0.05),辛前甘桔汤各剂量组lnc RNA SNHG16、EGFR、MUC5AC m RNA表达显著降低(P<0.05)。与羧甲司坦组比较,辛前甘桔汤高剂量组lnc RNA SNHG16、EGFR m RNA表达降低(P<0.05)。结论辛前甘桔汤能降低lnc RNA SNHG16、EGFR、MUC5AC m RNA表达,降低EGFR、MUC5AC蛋白表达,减少IL-6、IL-8、MMP-9表达,进而改善鼻黏膜病理改变。
