Objective To explore the effect of the simvastatin administration on the expression of connective tissue growth factor (CTGF) in fihrotic lungs of rats. Methods The cats were treated with single intratracheal instillation of bleomycin (BLM) or instillation of the same volume of normal saline (NS) as a control. The administration of simvastatin(20 mg/kg)began once a day immediately or 7 days later after intratracheal BLM instillation respectively with the same volume of NS was given as a vehicle control. The rats were killed on day 7,14 and 28 respectively. Pathological alteration of lung tissue was observed hy HE staining and Masson staining. Hydroxyproline(HYP)content in lung tissue was used to determine the severity of pulmonary fibrosis. The expression of CTGF in lung tissue was exanfined by immunohistochem- istry staining and photodeusitometry. Results Histopathological changes of pulmonary fibrosis emerged gradually after the instillation of BLM. The expression level of CTGF was increased in lungs of rats after intratracheal instillation of BLM, compared with the control. The administration of simvastatin immediately or 7 days after intratracheal instillation of BLM, attenuated the histopathological changes of bleomycin- induced puhnonary fibrosis and prevented the increased expression of CTGF in lung tissue on day 28. Conclusion The adntinistration of simvastatin, immediately or 7 days after intratracheal BLM instillation, prevented the up-regulation of CTGF in fibrotic lungs of rats, which ntight be one of the mechanisms of the anti-fihrosis of simvastatin in lungs.

A rapid method for the simultaneous determination of berberine (BBR), matrine (MT) and oxymatrine (OMT) by nonaqueous capillary electrophoresis (NACE) was developed. Optimum separation of the analytes was obtained on a 50cm×50μm i.d. fused-silica capillary using a non-aqueous buffer system of 70mM ammonium acetate, 7.0% acetic acid and 10% acetonitrile at 25kV and 20℃. The relative standard deviations (R.S.D.) of the migration times and peak areas of the three active components were 0.06%-0.20% and 0.12%-3.41% for berberine, 0.11%-0.60% and 0.74%-1.63% for matrine, 0.15% and 0.45% for oxymatrine, respectively. Detection limits of berberine, matrine and oxymtrine were 0.18μg/mL, 4.08μg/mL and 4.16μg/mL, respectively. In the tested concentration range, good linear relationships (0.9992 for berberine, 0.9988 for matrine and 0.9988 for oxymatrine) were observed. The linear calibration ranges were 0.45-360.0μg/mL for berberine, 8.16-408.0μg/mL for matrine and 20.8-416.0μg/mL for oxymatrine. This method has been successfully applied to the phytochemical analysis of alkaloids extracts from two commonly used traditional Chinese herbal drugs: Sophora flavescens Ait. (Kushen) and Cortex phellodendri chinensis (Huangbai) and their medicinal preparations.
