  • The Effect of Oral Xiaoyan Lidan Tablets on The Bile Composition in Patients with Intrahepatic Bile Duct Stones

    ObjectiveTo observe the effects of oral Xiaoyan Lidan tablets(XYLDT) on the bile composition(total bile acids, cholesterol, phospholipids) in patients with intrahepatic duct stones after common bile duct exploration(CBDE) with T tube drainage, to explore its possible preventive effects on stone recurrence. MethodsForty consecutive patients with intrahepatic bile duct stones who underwent CBDE with T tube drainage were randomly divided into experi mental group and control group. XYLDT were administrated at day 4 after surgery in experimental group(n=20), while none of medication were given in control group(n=20). 2 mL of bile was collected through T tube in both groups at day 1, 2, 3, 7, 14, and 21 postoperatively. Total bile acids(TBA), cholesterol(CHO), and phospholipids(PLIP) in bile were measured, and TBA/CHO ratio and PLIP/CHO ratio were calculated respectively. The results were statistical analyzed. ResultsThe demographic data in both groups including age, gender, height, weight, preoperative concomitant diseases, operative time, postoperative complications, hospital stays, serum total bilirubin, direct bilirubin, alanine aminotransferase(ALT), aspartate aminotransferase(AST), and amylase were not significantly different(P > 0.05). The measurements of TBA, CHO, PLIP, and the ratio of TBA/CHO and PLIP/CHO in bile were not significant on day 1, 2, and 3 after surgery in both groups(P > 0.05). In experimental group, the TBA, CHO, and PLIP on day 7, 14, and 21 after surgery were significantly increased compared with the control group(P < 0.05). The ratio of TBA/CHO on day 7, 14, and 21 was 2.17±0.29, 2.29±0.44, and 2.59±0.58, the ratio of PLIP/CHO was 2.03±0.68, 2.84±0.64, and 2.86±0.77, respectively, which were also significantly increased compared with the control group(P < 0.05). ConclusionsOral XYLDT can increase the secretion of TBA, CHO, and PLIP, elevate the TBA/CHO and PLIP/CHO ratio, and change the bile composition which may increase the dissolution of cholesterol in the bile. Presumably, oral XYLDT may have preventive effects in the recurrence of intrahepatic bile duct stones.

  • Initial Study on Effect of Peroxisome Proliferator-Activated ReceptorγAgonist on Bile Duct Fibrosis Induced by Transforming Growth Factor-β1

    ObjectiveTo investigate the effect of peroxisome proliferator-activated receptorγ(PPARγ) agonist on bile duct fibrosis induced by transforming growth factor-β1 (TGF-β1). MethodsPrimary cultures of bile duct fibroblast were treated with different concentrations of pioglitazone (PGZ) or 15-deoxy-Δ12, 14-prostaglandin J2 (15d-PGJ2) and then treated with TGF-β1. The mRNA levels of collagenⅠ(COLⅠ)、fibronectin (FN)、α-smooth muscle actin (α-SMA) and connective tissue growth factor (CTGF) were determined by RT-PCR. ResultsPGZ and 15-d-PGJ2 could down regulated the mRNA levels of COLⅠ, FN, α-SMA and CTGF induced by TGF-β1 (3 ng/mL). The same concentration of 15d-PGJ2 was a more potent inhibitor ofα-SMA and less potent inhibitor of COLⅠthan PGZ. But PGZ had the same effect as 15d-PGJ2 on CTGF. ConclusionPPARγagonist can prevent fibrosis induced by TGF-β1.
