Clinical and experimental study on wuling pill in treating gestation period intrahepatic cholestasis / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the curative effect of Wuling pill (WLP), a traditional Chinese patent medicine, in treating gestation period intrahepatic cholestasis (GPI).</p><p><b>METHODS</b>In the clinical study, 90 GPI patients were divided into the treated group treated by conventional therapy plus WLP and the control group treated by conventional therapy plus compound Yiganling (YGL) with a ratio of 21. Clinical symptoms and accouchement condition were observed. Levels of cholyglycine acid (CGA), total and direct bilirubin (TB and DB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) were detected before and after treatment. For the experimental study, GPI rat model was induced by injecting estradiol benzoate to pregnant Wistar rats. The model rats in the treated group were administrated with WLP by gastro-perfusion and those in the control group, were administrated with YGL. Levels of CGA,TB,DB, ALT, AST and ALP in the mother and fetal rats, as well as in the amnionic fluid were determined. Besides, the volume of bile excreted by the mother rats was observed.</p><p><b>RESULTS</b>In clinical trials, the markedly effective rate in the treated group (47 cases, 78.3% ) was higher than that in the control group (15 cases, 50%, chi2 = 7.17286, P < 0.01). Levels of blood CGA, TB, ALT and AST were all decreased in both groups after treatment, but WLP showed a better efficacy than YGL (P < 0.05) in lowering CGA, ALT and AST. Moreover, the occurrence of meconium contaminated amnionic fluid and premature delivery were lower, while weight and Apgar grade of newborn babies were higher in the treated group than those in the control group. In animal experiment, WLP showed significant effects in decreasing CGA level in amniotic fluid, and in blood of the mother and fetal rats. In addition, it could also decrease the levels of bilirubin, ALT and AST, and promote the bile excretion to reduce CGA concentration in bile. All the above effects showed a dose-dependent pattern.</p><p><b>CONCLUSION</b>WLP could effectively lower the serum bile acid, improve the hepatic function and better the pregnant outcome in treating GPI.</p>
