OBJECTIVE: To observe the changes of intracellular free calcium level ([Ca(2+)]i) in gallbladder cells of guinea pigs with gallstones so as to study the mechanisms of gallstone formation and the prevention and treatment function of traditional Chinese herbs for nourishing the liver. METHODS: Eighty guinea pigs were randomly divided into four groups, which were normal control group, untreated group, nourishing-liver Chinese drug (NLCD) group and ursodeoxycholic acid (UDCA) group, with 20 guinea pigs in each group. Gallstones were induced in the guinea pigs of the latter 3 groups by the feed of diet inducing cholelithiasis with high cholesterol, while the corresponding medicines were used in NLCD group and UDCA group for prevention and treatment for 7 weeks. Then the state of the guinea pigs, the formation of gallstones, and the changes of [Ca(2+)]i in gallbladder cells were observed. RESULTS: The [Ca(2+)]i in gallbladder cells of guinea pigs in the untreated group was decreased significantly. NLCD improved the behavioral signs of the guinea pigs, significantly decreased the formative rate of gallstones and increased the [Ca(2+)]i in gallbladder cells. CONCLUSIONS: The [Ca(2+)]i in gallbladder cells is the important factor for contractile function of gallbladder and the information of gallstones. Traditional Chinese herbs for nourishing the liver may significantly increase the [Ca(2+)]i in gallbladder cells to facilitate contraction of the smooth muscle cells of gallbladder and relieve the cholestatis. It may be one of the mechanisms of traditional Chinese herbs for nourishing the liver in preventing and treating cholelithiasis.

OBJECTIVE: To explore the mechanism of the inhibiting effects of recipe for dispersing stagnated liver qi to promote bile flow (Danshijing Tablets) on cholesterol gallstone formation and provide experimental evidence for its clinical application. METHODS: Eighty guinea pigs were randomly divided into 4 groups, which were normal control group, untreated group, ursodeoxycholic acid (UDCA)-treated group and Danshijing Tablets-treated group. The gallstones in guinea pigs were induced by high-cholesterol diet. UDCA and Danshijing Tablets were given orally to guinea pigs in the corresponding group respectively for seven weeks. Then the physical signs of the guinea pigs, the rates of gallstone formation and the histomorphological changes of the gallbladder were examined. RESULTS: The behavior of guinea pigs in the Danshijing Tablets-treated group was obviously improved and the rate of gallstone formation was significantly decreased as compared with those in both untreated and UDCA-treated groups (P<0.05). The inflammation reaction of mucous membrane in gallbladder was evidently reduced in the Danshijing Tablets-treated group and its morphological appearance turned to be approximately normal. CONCLUSION: Recipe for dispersing stagnated liver qi to promote bile flow may decrease gallstone formation. Its mechanism may be related to reducing pathologic changes in gallbladder tissues, which will reduce the damages of cholesterol to the smooth muscle in gallbladder and enhance the contractility of gallbladder.

Rivaroxaban is one of the new oral anticoagulants (NOAC) for preventing stroke and systemic embolism in patients with non-valvular atrial fibrillation. It has clear pharmacokinetic parameters, stable plasma concentration, less drug-drug interaction and higher compliance of patients. However, the discrepancy of pharmacokinetics between individuals and drug-induced hemorrhage events frequently occur clinically, therefore the association of gene polymorphism with drug metabolism has become a research hotspot. This article reviews the research progress on pharmacokinetic characteristics of rivaroxaban and its relationship with gene polymorphism, to provide a reference for the individualized rational use of rivaroxaban.
