ABSTRACT
OBJECTIVE: To evaluate the efficacy and safety of Danning Tablet (DNT) in patients with non-alcoholic fatty liver disease (NAFLD) of damp-heat syndrome type. METHODS: A multicenter, randomized, double-blinded and positive drug parallel controlled trial was performed. One hundred and thirty-five patients were enrolled into the study and divided into two groups: DNT-treated group (n=102) and ursodeoxycholic acid (UDCA)-treated group (n=33). Body mass index (BMI), principal symptoms, liver function, blood lipids, iconographic, and compositional parameters were measured before and after treatment, respectively. RESULTS: In the two groups, BMI, distress in hepatic region, fatigue, anorexia, liver function, blood lipids and iconographic parameters were significantly improved, and the improvements of BMI, distress in hepatic region were better in DNT-treated group than in UDCA-treated group. The histological study also showed that DNT had positive effect in treatment of NAFLD. CONCLUSION: DNT is an effective drug to treat patients with NAFLD of damp-heat syndrome type and is more effective than UDCA.
ABSTRACT
OBJECTIVE: To observe the effects of Qingdan Capsule (QDC) and Yanggan Lidan Granule (YGLDG), two kinds of compound traditional Chinese herbal medicines, on biochemical parameters in guinea-pigs with pigment gallstones. METHODS: An animal model of pigment gallstones was established in male guinea-pigs by hypodermic injection of lincomycin. The guinea-pigs were randomly divided into blank control group, untreated group, QDC group and YGLDG group. There were 8 guinea-pigs in each group. After ten-day treatment, animals were sacrificed and sampled to calculate the rate of stone formation, total bilirubin (TB), unconjugated bilirubin (UCB) and Ca2+ density in bile of the four groups. RESULTS: In comparison with the untreated group, the rates of stone formation in the QDC and YGLDG groups were significantly decreased (P<0.01). TBIL, UCB and Ca2+ content of bile in both QDC and YGLD groups was also significantly decreased (P<0.05, P<0.01). CONCLUSION: QDC and YGLD have good effects on biochemical changes of animal model of pigment gallstone in reversing the lithogenesity of bile by reducing the content of TB, UCB and Ca2+, hence resulting in clinical treatment and prevention of pigment gallstone disease.
ABSTRACT
OBJECTIVE: To observe the effects of Shengqing Capsule (SQC), a compound of traditional Chinese herbal medicine, on biochemical parameters in C57BL/6J mice with cholesterol gallstone. METHODS: Thirty-eight C57BL/6J mice were randomly divided into normal control group (n=10), untreated group (n=15) and SQC group (n=13). Cholesterol gallstone was induced in mice of the latter two groups by feeding high cholesterol diet. Mice in the SQC group were intragastricly administered SQC 0.22 g/(kg.d). After 8-week treatment, animals were sacrificed and sampled to calculate the incidences of stone formation. The contents of serum cholesterols and Ca(2+), and the malonaldehyde (MDA) content and superoxide dismutase (SOD) activity in liver tissues were detected. RESULTS: The incidences of stone formation were 73.33% in untreated group, 0% in normal control group, and 23.08% in the SQC group. And the INCIDENCE in untreated group was significantly higher than those in the normal control group and the SQC group (P<0.01). Contents of serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in the SQC group were lower than that in the untreated group (P<0.01), and high-density lipoprotein cholesterol (HDL-C) in the SQC group was higher than that in the untreated group (P<0.01). SQC could increase the SOD activity and decrease the MDA content in liver tissues, showing significant differences as compared with those in the untreated group (P<0.05). CONCLUSION: SQC can decrease the incidence of stone formation and improve the biochemical parameters, which may be one of the mechanisms in the treatment and prevention of cholesterol gallstone disease.
ABSTRACT
OBJECTIVE: To study the mechanisms of Shengqing Capsules, a compound Chinese herbal medicine for dispersing stagnated liver qi and promoting bile flow, in prevention and treatment of pigment gallstone. METHODS: Liver cells from guinea pigs with pigment gallstone were primarily cultured in vitro. The serums containing different concentrations of Shengqing Capsules were prepared by serum pharmacological method. The primary cultured hepatocytes with excessive expression of nuclear factor-kappaB (NF-kappaB) were stimulated with lipopolysaccharides (LPS) and the effects of the drug-containing serums on the NF-kappaB expression were detected by Western-blotting. RESULTS: Shengqing Capsules down-regulated the NF-kappaB expression increased by LPS stimulation. The effect is dose-dependent. CONCLUSION: Shengqing Capsules can down-regulate the NF-kappaB expression increased by LPS stimulation. It may be one of the important mechanisms of this Chinese herbal medicine in prevention and treatment for pigment gallstone formation and the inflammatory reaction in biliary tract.
ABSTRACT
OBJECTIVE: To investigate the effects of antipyretic and purgative herbs on intestinal mucosal barrier and inflammatory response in the treatment of acute cholangitis. METHODS: Sixty SD rats were randomly divided into group A (untreated group, acute cholangitis was induced, n=20), group B (treatment group, acute cholangitis was induced and treated with antipyretic and purgative herbs, n=20) and group C (sham operation group, n=20). At the third or fifth day after operation, the rats were sacrificed and sampled. The serum endotoxin, cytokines and inflammatory mediators were tested and the numbers of labeled bacteria in the liver, spleen and mesenteric lymph nodes translocated from the gut were assayed. RESULTS: As compared with group A, the serum content of endotoxin, IL-6, IL-8, TNF-alpha, CRP and NO was significantly lower and that of IL-2 was significantly higher, and the translocated numbers of labeled bacteria from gut were reduced in both group B and group C (P<0.01). CONCLUSION: Antipyretic and purgative herbs can play therapeutic roles in the treatment of acute biliary tract infections, including the protection of intestinal mucosal barrier from bacterial translocation, reduction of serum endotoxin content and regulation of inflammatory response.
