Cholagogic traditional Chinese medicines refer to those that can promote bile secretion and excretion, strengthen gallbladder contraction and promote gallbladder emptying. They are mainly used to treat cholecystitis, gallstones, cholestasis, biliary tract infection, jaundice hepatitis and other diseases in clinical application. As a traditional medicine in our country, Chinese herbal medicines have many advantages, such as extensive resources, low cost, little or no toxic and side effects, and in addition, it is not easy for animals to produce drug resistance. With the progress of science and technology and the rapid development of traditional Chinese medicine, many achievements have been made in the research of cholagogic traditional Chinese medicines. Traditional Chinese medicine plays a cholagogic role mainly by promoting bile secretion, regulating SCP2 mRNA, FXR, BSEP and efflux transporter protein, dissolving cholesterol, promoting the relaxation of Oddi's sphincter and changing the composition of bile, etc. Traditional Chinese medicine decoction, traditional Chinese medicine preparation, Chinese medicine combined with acupuncture, ear acupoint pressing, soaking bath, western medicine and alike are often used to treat biliary system diseases in clinical practice. The effective rate of combination of traditional Chinese medicine and other methods was significantly higher than that of compound prescription, western medicine, acupuncture and soaking bath alone. General attack therapy and new therapies are also used in clinical treatment. The clinical effect of traditional Chinese medicine is remarkable. By means of literature review, the pharmacological effects, mechanism and clinical application of Chinese herbal medicines and compound prescriptions with gallbladder-promoting effect in the past 15 years were summarized in this paper. At the same time, some existing problems were found and prospects were expected.

Daily administration of glucocorticoids for 10 days to dogs resulted in a significant increase in the hepatic bile secretion in response to secretory stimulants. The response of hepatic bile in testosterone-treated animals was not changed and the response was increased in DOCA--treated animals. A significant increase of liver weight was induced by the animals receiving glucocorticoids. Other organ weight was not changed; however, a slight reduction of kidney weight was seen in prednisolone, dexamethasone, and DOCA treated animals and also in animals supplemented with cortisone following adrenalectomy. The presence of large areas of ballooning and vesicular changes of liver cells was seen in glucocorticoid treated animals, particularly in cases of dexamethasone and prednisolone. Both vesicular changes of liver cell and its glycogen content were increased by the repeated administration of prednisolone and reduced by the cessation of treatment. Special stain and liver glycogen determination demonstrated the material distending the liver cell was glycogen. These findings indicate that long term administration of glucocorticoids results in an increase of liver weight and hepatic glycogen content as well as increased bile secretion.

To evaluate the efficacy and safety of ursodeoxycholic acid (UDCA) with oral solubilized formula in amyotrophic lateral sclerosis (ALS) patients, patients with probable or definite ALS were randomized to receive oral solubilized UDCA (3.5 g/140 mL/day) or placebo for 3 months after a run-in period of 1 month and switched to receive the other treatment for 3 months after a wash-out period of 1 month. The primary outcome was the rate of progression, assessed by the Appel ALS rating scale (AALSRS), and the secondary outcomes were the revised ALS functional rating scale (ALSFRS-R) and forced vital capacity (FVC). Fifty-three patients completed either the first or second period of study with only 16 of 63 enrolled patients given both treatments sequentially. The slope of AALSRS was 1.17 points/month lower while the patients were treated with UDCA than with placebo (95% CI for difference 0.08-2.26, P = 0.037), whereas the slopes of ALSFRS-R and FVC did not show significant differences between treatments. Gastrointestinal adverse events were more common with UDCA (P < 0.05). Oral solubilized UDCA seems to be tolerable in ALS patients, but we could not make firm conclusion regarding its efficacy, particularly due to the high attrition rate in this cross-over trial.

A stable and reliable infected necrotizing pancreatitis (INP) model in rats was established in order to study the pathophysiological mechanism and pathological development rule of INP and explore the new therapeutic methods for the diseases. Forty-six SD rats were randomly divided into 5 groups. The animals in group A received the injection of 5% sodium taurocholate into the pancreatic duct and those in group B underwent that of E. coli into the pancreatic duct. The rats in groups C, D and E were subjected to the injection of 5% sodium taurocholate in combination with different concentrations of E. coli (10(3), 10(4), 10(5)/mL, respectively) into the pancreatic duct. The dose of injection was 0.1 mL/100 g and the velocity of injection was 0.2 mL/min in all the 5 groups. Eight h after the injection, the survival rate of animals was recorded and the surviving rats were killed to determine the serum content of amylase and perform pathological examination and germ cultivation of the pancreatic tissue. The results showed that acute necrotizing pancreatitis model was induced by injection of 5% sodium taurocholate into the pancreatic duct. The positive rate of germ cultivation in group A was 12.5%. The acute necrotizing pancreatitis model was not induced by injection of E. coli into the pancreatic duct and the positive rate of germ cultivation in group B was 0. The INP model was established in groups C to E. The positive rate of germ cultivation was 60%, 100% and 100% and 8-h survival rate 100%, 100% and 70% in groups C, D and E, respectively. It was concluded that a stable and reliable model of INP was established by injection of 5% sodium taurocholate in combination with 10(4)/mL E. coli into the pancreatic duct with a dose of 0.1 mL/100 g and a velocity of 0.2 mL/min. The pathogenesis of INP might be that the hemorrhage and necrosis of pancreatic tissue induced by sodium taurocholate results in weakness of pancreatic tissue in fighting against the germs. Meanwhile, the necrotic pancreatic tissue provides a good proliferative environment for the germs.

OBJECTIVE: To investigate the effects of genipin on promoting brown adipose tissue activation and white adipose tissue browning. METHODS: The male C57BL/6J mice were divided into three groups: normal control group, genipin group and cold-stimulus group.Genipin group were treated consecutively with genipin at a dose of 15 mg/kg once a day for 9 days, normal control group were treated with the saline.The mice with cold-stimulus were exposed to 4℃ environment for 5 days.Daily food amount and body weight were measured.Morphological changes were observed in the subscapular region, inguinal region and epididymis around the adipose tissue.The expression of uncoupling protein 1 (UCP1) was determined by real-time PCR and Western blot respectively. RESULTS: The wet weight of white fat in genipin-treated mice was decreased by 16% , and 28% in that of cold-stimulus mice, compared with the normal control group (P＜0.05).After treatments of genipin and cold-stimulus, the color of white adipose tissues was darker, and the size of lipid droplets in adipocytes was smaller, whereas the number was increased.Compared with the normal control group, UCP1 expression was increased obviously in fat tissues, including the subcutaneous and visceral white adipose tissues, and brown adipose tissue after treated with genipin and cold-stimulus (P＜0.05). CONCLUSION Genipin promoted activation of brown adipose tissue and browning of white adipose tissue by upregulating UCP1 expression, which could contribute to the loss of body weight against obesity.

OBJECTIVETo provide evidence for three-level prevention of cholelithiasis by means of observing the effects of some choleretics on bile compositions drained from patients with pigment gallstone.

METHODSTwenty-seven patients suffering from primary pigment gallstones and having received treatment of choledochostomies plus T-tube or endoscopic nasal bile drainage (ENBD) were divided equally into three groups, and administered respectively with Lidanling (the LDL group), ursodesoxycholic acid (the UDA group) and combination of LDL and UDA (the LDL + UDA group) through oral intake (7 patients in each group). Besides, 6 post-operational patients got no treatment with any drug were allocated in the control group. Bile of all the patients was collected before treatment and on the 1, 3, 5, 7 th day after the treatment started to detect levels of total bile acid (TBA), glycocholic acid (GCA), taurocholic acid (TCA), glycocholic cheno-desoxycholic acid (GCDCA), total bilirubin (TBIL), uncombined bilirubin (UCB), concentration of calcium ion (Ca(2+)) as well as the bacterio-genetic and endogenous beta-glucuronidase activity for comparing.

RESULTSLevels of TBA, GCA, TCA and GCDCA got gradually increased in the UDA group and the LDL + UDA group after treatment (P < 0.05), while those in the LDL group remained unchanged, showing an insignificant difference as compared with those in the control group. In the LDL group and the LDL + UDA group, TBIL gradually increased while UCB gradually decreased in the course of treatment (P < 0.05). Moreover, levels of Ca(2+) and endogenous beta-glucuronidase activity got significantly lowered (P < 0.05).

CONCLUSIONCombined use of LDL and UDA could elevate levels of TBA, GCA, TCA, GCDCA, enhance the excretion of TBIL in patients with pigment gallstone after bile drainage, lower levels of UCB and Ca(2+) and the activity of endogenous beta-glucuronidase in the bile, so as to reduce the possibility of stone formation of bile, and therefore, it could be used to prevent the production of pigment gallstone, especially to prevent post-operative recurrence of stones.

Nonalcoholic steatohepatitis (NASH) can progress into liver cirrhosis; however, no definite treatment is available. Omega-3 polyunsaturated fatty acid (omega-3) has been reported to alleviate experimental NASH, although its beneficial effect was not evident when tested clinically. Thus, this study aimed to investigate the additive effect of omega-3 and ursodeoxycholic acid (UDCA) on diet-induced NASH in mice. C57BL/6 mice were given a high-fat diet (HFD) for 24 weeks, at which point the mice were divided into three groups and fed HFD alone, HFD with omega-3 or HFD with omega-3 in combination with UDCA for another 24 weeks. Feeding mice an HFD and administering omega-3 improved histologically assessed liver fibrosis, and UDCA in combination with omega-3 further attenuated this disease. The assessment of collagen alpha1(I) expression agreed with the histological evaluation. Omega-3 in combination with UDCA resulted in a significant attenuation of inflammation whereas administering omega-3 alone failed to improve histologically assessed liver inflammation. Quantitative analysis of tumor necrosis factor alpha showed an additive effect of omega-3 and UDCA on liver inflammation. HFD-induced hepatic triglyceride accumulation was attenuated by omega-3 and adding UDCA accentuated this effect. In accordance with this result, the expression of sterol regulatory binding protein-1c decreased after omega-3 administration and adding UDCA further diminished SREBP-1c expression. The expression of inducible nitric oxide synthase (iNOS), which may reflect oxidative stress-induced tissue damage, was suppressed by omega-3 administration and adding UDCA further attenuated iNOS expression. These results demonstrated an additive effect of omega-3 and UDCA for alleviating fibrosis, inflammation and steatosis in diet-induced NASH.

BACKGROUNDHepatic fibrosis is the key stage of the pathological progress from hepatic injury to cirrhosis. Ursodeoxycholic acid (UDCA) has been known as having significant clinical therapeutic effects on chronic liver diseases. Our research aimed to study the effect of UDCA on the signaling pathway of transforming growth factor beta1 (TGFbeta1)/Smad and discuss its possible molecular mechanisms of inhibiting hepatic fibrosis.

METHODSRat hepatic stellate cells were cultured in vitro and randomly assigned to 4 groups. Group A was control group, with only DMEM culture medium applied, and groups B, C, D were experimental groups, with different doses of UDCA (1.0 mmol/L, 0.5 mmol/L and 0.25 mmol/L respectively) added into their DMEM culture medium for further culture of 24 hours and 48 hours. The protein expressions of TGFbeta1, TGF type I receptor, Smad3, Smad4 and Smad7 were measured by Western blotting, as well as the expressions of TGFbeta1, Smad3, Smad7 and cAMP response element (CREB) binding protein (CBP) mRNA by real-time PCR. SPSS 11.5 statistical package was adopted for data analyses.

RESULTSCompared with control group, the mRNA expressions of TGFbeta1 in the high and middle UDCA dose groups for 24 hours and 48 hours significantly decreased (P < 0.05), the protein expressions of TGFbeta1 in the two above groups for 48 hours and in the high dose group for 24 hours significantly decreased (P < 0.05). The protein and mRNA expressions of Smad3 in each UDCA dose group for 24 hours and 48 hours significantly decreased, with significant difference among different UDCA dose groups and between that of 24 hours and 48 hours observed (P < 0.05). The protein and mRNA expressions of Smad7 in the high and middle UDCA dose groups for 24 hours and 48 hours significantly increased. The CBP mRNA expression in each UDCA dose group for 24 hours and 48 hours significantly decreased (P < 0.05), with significant difference among different UDCA dose groups observed (P < 0.05).

CONCLUSIONUDCA could curb the development of hepatic fibrosis through affecting the signaling pathway of TGFbeta1/Smad by inhibiting the expressions of TGFbeta1, Smad3 and CBP and increasing the expression of Smad7.
