    ABSTRACT: To observe the effects of Yanggan Lidan Granule (YGLDG), a compound traditional Chinese herbal medicine, on insulin resistance in guinea pigs with induced cholesterol gallstones. Eighty guinea pigs were randomly divided into normal control group, untreated group, YGLDG group and ursodeoxycholic acid (UDCA) group, with 20 guinea pigs in each group. Except the normal control group, gallstones were induced by high-cholesterol diet in the guinea pigs. The guinea pigs in the normal control group and the untreated group were administered with normal saline. UDCA and YGLDG were given to the guinea pigs in the corresponding groups for seven weeks. Eight guinea pigs of each group were used to measure the glucose infusion rate (GIR) by using hyperinsulinemic-euglycemic clamp technique. At the end the guinea pigs were killed and their gallstone formation was observed. The gallstones in guinea pigs were identified as cholesterol stones by qualitative analysis through infrared spectrum. The incidence rate of cholelithiasis of the untreated group was 82.35% . The GIR of guinea pigs in the untreated group was obviously lowered down as compared with the normal control group. Compared with the untreated group, the GIRs of the YGLDG group and the UDCA group were obviously increased, especially in the YGLDG group. YGLDG may improve insulin resistance in guinea pigs with cholesterol gallstones by elevating GIR obviously.

    ABSTRACT: To study the role of estrogen receptor (ER) and progesterone receptor (PR) in the formation of cholesterol calculus and investigate the effects of Shengqing Capsule (SQC), a Chinese patent herbal medicine with the function of soothing liver and draining gallbladder, on ER and PR expressions. A total of 80 female guinea pigs were divided into normal control group, untreated group, ursodeoxycholic acid group (UDCA group) and SQC group. The cholesterol gallstone was induced by feeding the guinea pigs with high-fat lithogenic diet. SQC and UDCA were separately administered to the guinea pigs in the SQC group and UDCA group. After 7-week administration, all the animals were sacrificed to calculate the incidence of calculus formation and detect the expressions the ER and PR in the epithelial tissue of gallbladder by immunohistochemical method. Gallstone was cholesterol calculus detected by infrared spectrum. The incidence of calculus formation in the SQC group (27.78%) was significantly lower than that in the untreated group (81.25%) (X(2)=9.721 5, P=0.001 8). On the basis of Reiner standard, the expression distribution of ER and PR increased gradually from the normal control group through the SQC group and UDCA group to the untreated group. Except for the former two groups and the latter two groups, the differences between the other groups and UDCA group were statistically significant (P<0.05). Besides, the differences of positive expression rates between groups were statistically significant (P<0.05). Increased expressions of ER and PR are closely related to the formation of cholesterol stone. And Shengqing Capsule can down-regulate the expressions of ER and PR.

    ABSTRACT: To explore the effects of Yanggan Lidan Granule (YGLDG), a compound traditional Chinese herbal medicine for nourishing liver and improving choleresis, on the rate of gallstone formation and content of plasma cholecystokinin in guinea pigs with induced cholesterol gallstones. Eighty guinea pigs were randomly divided into 4 groups, which were normal control group, untreated group, YGLDG-treated group and ursodeoxycholic acid (UDCA)-treated group (n=20). Except the normal control group, gallstones were induced by high-cholesterol diet in the guinea pigs. YGLDG (1.81 g/kg daily) and UDCA (30.12 mg/kg daily) were given orally to guinea pigs in the corresponding group respectively for seven weeks; however, the guinea pigs of normal control group and untreated group were administered with normal saline. The physical signs of the guinea pigs and the rates of gallstone formation were examined, and the content of cholecystokinin (CCK) in the plasma was detected by radio-immunoassay. YGLDG could obviously improve the ethological signs of the guinea pigs. Gallstone formation rate of the untreated group (82.35%) was significantly increased as compared with that of the normal control group (5.26%) (P<0.01), while the gallstone formation rates of the YGLDG-treated group (27.28%) and UDCA-treated group (38.89%) were lower than that of the untreated group (P<0.05). The content of CCK in plasma of the untreated group was significantly lower than that of the normal control group (P<0.01), while CCK content of the YGLDG-treated group and UDCA-treated group was lower than that of the normal control group, but both of them were significantly higher than that of the untreated group (P<0.01). The difference of CCK levels between YGLDG-treated group and UDCA-treated group had no statistical significance (P>0.05). YGLDG can significantly decrease the rate of gallstone formation in guinea pigs. It may be related to elevating the content of CCK in the plasma.

    ABSTRACT: 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. 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. 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. 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.

    ABSTRACT: To study the mechanisms of Tongxia Huayu Decoction (a Chinese herbal decoction for purgation and removing blood stasis) in prognostic improvement for severe acute pancreatitis by early intervention on pancreatic microcirculatory disturbance. Fifty-three patients with severe acute pancreatitis were divided randomly into treatment group (n=28) and control group (n=25). Tongxia Huayu Decoction was given to the patients in treatment group in addition to the normal treatment in control group for one week. The clinical symptoms and signs, hemodiastase, urinary amylase, C-reactive protein (CRP) and endothelin (ET) of the patients in the two groups before and after treatment were observed and detected. The total response rate of the treatment group was 98.4%, while that of the control group was 80%, with significant difference between them (P<0.05). There was no significant difference of the contents of hemodiastase, urinary amylase, CRP and ET between the two groups before treatment, while they were significantly decreased after treatment (P<0.01) with more obvious change in treatment group (P<0.01). Tongxia Huayu Decoction brings satisfied therapeutic effect on severe acute pancreatitis. The mechanisms may associate with its reducing function on ET releasing so as to inhibit the pancreatic microcirculatory disturbance and acinar cell injury induced by ET.

    ABSTRACT: To evaluate the clinical outcome of Ruanjian Xiaoying Decoction (RJXYD) on chronic lymphocytic thyroiditis. Eighty patients with chronic lymphocytic thyroiditis were randomly divided into RJXYD-treated group (n=40) and control group (n=40). The patients in the RJXYD-treated group received treatment of RJXYD combined with levothyroxine while the others in the control group received treatment of levothyroxine and prednisone both for 16 weeks. The serum levels of thyroid hormones and the titres of serum antithyroglobulin antibody (anti-TG Ab) and antithyroid microsomal antibody (anti-TM Ab) were all examined before and after treatment. The total response rates of the two groups were evaluated after treatment of 16 weeks. The total response rate of the RJXYD-treated group was 92.5%, while that of the control group was 60.0% (P<0.01). The serum levels of free triiodothyronine (FT(3)) and free thyroxine (FT(4)) were obviously increased after treatment as compared with those before treatment in the two groups. The titres of serum anti-TG Ab and anti-TM Ab and the serum level of thyroid-stimulating hormone (TSH) were all obviously decreased after treatment as compared with those before treatment in the two groups. The RJXYD can shrink and soften the enlarged thyroid gland and thyroid nodules, improve the immune function of human body, alleviate the response to thyroid self-antigens and promote the recovery of thyroid function.

    ABSTRACT: 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. 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. 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. 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.
