藏药二十五味松石丸的处方考证与药理作用及临床应用研究进展

二十五味松石丸(Ershiwuwei Songshi Pills,ESP)为藏医治疗肝胆疾病的常用经典方剂,具有清热解毒、疏肝利胆及化瘀等功效。通过梳理传统藏医药本草典籍及现代论著,系统考证了ESP的处方来源及历史变迁,初步探讨并核实组成药味的基原。现代研究表明ESP具有抗肝损伤、抗肝纤维化、改善非酒精性脂肪肝、抑菌及抗内毒素血症等作用。在现代临床应用中,ESP广泛用于治疗病毒性肝炎、脂肪肝、慢性胆囊炎及肝硬化等肝胆系统疾病。通过考证ESP的处方演变,归纳其药理作用和临床功效,为该成方制剂的临床合理应用和二次开发提供参考依据。

Cholecystokinin octapeptide inhibits the in vitro expression of CD14 in rat pulmonary interstitial macrophages induced by lipopolysaccharide

OBJECTIVE: To study the effect of cholecystokinin octapeptide (CCK-8) on lipopolysaccharide (LPS)-stimulated pulmonary interstitial macrophages (PIM) in vitro. METHODS: PIM were isolated and cultured in the presence or absence of LPS, CCK-8, proglumide (the antagonist of CCK receptors) and vehicle. The expression of membrane CD14 (mCD14) protein was assayed by flow cytometry and soluble CD14 (sCD14) in the supernatant was analyzed semi-quantitatively by Western blot. TNF-alpha in the supernatant was detected with ELISA. RESULTS: CCK-8, at concentrations of 10(-7) mol/L and 10(-6) mol/L, significantly inhibited the expression of mCD14. Release of sCD14 and TNF-alpha in the supernatant was up-regulated by LPS (1 microg/ml) but reduced by CCK-8. The effect of CCK-8 was inhibited by proglumide. CONCLUSION: CCK-8 negatively modulated several functions of LPS-stimulated PIM through CCK receptors. This may be one of the mechanisms for CCK-8 to alleviate inflammation in lung tissue during endotoxemia.
