BACKGROUND: It has been considered that Cestrum nocturnum L. (CNL) has the effects of antiarrhythmia, local anesthesia and central inhibition.OBJECTIVE: To investigate the analgesic effect of CNL extract on mice,so as to find new drugs for clinical treatment of pain.DESIGN: A randomized control observation.SETTING: Center of Modern Education and Department of Pharmacology,Gannan Medical College.MATERIALS: The experiments were carried out in the laboratory of scientific research center, Gannan Medical College between March and April in 2005. ① A total of 150 healthy adult Kunming mice were used in four independent experiments. ② Drugs: CNL extract was provided by the Department of Phytochemistry, Shenyang Pharmaceutical University (batch number: 2002080901), morphine hydrochloride injection by Shenyang No.1Pharmaceutical Factory (batch number: 000305), and naloxone hydrochloride injection by Yanqiao (Hunan) Pharmaceutical Co. Ltd., (batch number:20021109).METHODS: ① Effects of CNL extract on writhing times induced by acetic acid: Forty female mice were randomly divided into four groups with10 mice in each, and they were treated with intraperitoneal injections of 0.02 mL/g saline, 0.10 and 0.20 mg/g CNL extract and 0.10 mg/g aminophenazone respectively. The intraperineal injection of 6 g/L glacial acetic acid was given after 15 minutes. The writhing times of mice within 15 minutes were observed and recorded in each group. ② Effects of CNL extract on the pain induced by hot pla in mice: Forty female mice were randomly divided into four groups with 10 mice in each, and they were treated with intraperineal injections of 0.02 mL/g saline, 0. 10 and 0.20 mg/g CNL extract and 0.10 mg/g morphine respectively. The pain responses were detected at 15, 30 and 60 minutes after administration. ③ The antagonistic effect of naloxone on morphine and CNL extract to the pain induced by hot plate in mice: Thirty female mice were randomly divided into three groups ith 10 mice in each group, and they were given intraperitoneal injections of 0.02 mL/g saline, naloxone 0.004 mg/g +morphine 0.01 mg/g and naloxone 0.004 mg/g+CNL extract 0.01 mg/g respectively. The pain responses were detected at 15, 30 and 60 minutes after administration respectively. ④ Effects of CNL extract on electrostimulation induced pain in mice: Forty mice were randomly divided into four groups with 10 mice in ach group, and they were administrated with intraperineal injections of 0.02 mL/g saline, 0.10 and 0.20 mg/g CNL extract and 1 g/L morphine respectively. Repeated electrostimulations were given at 20, 35, 50 and 70minutes after administration, and the pain responses were detected by means of electrostimulation.MAIN OUTCOME MEASURES: ① Writhing times; ② Time for the pain response induced by hot plate; ③ Analgesic rate induced by electrostimulation.RESULTS: Totally 150 healthy adult Kunming mice were used in the four independent experiments, and all were involved in the analysis of results. ①Writhing times in the mice: 0.10 and 0.20 mg/g CNL extracts and 0.10 mg/g aminophenazone had very significant analgesic effects on writhing induced byacetic acid in mice, and the writhing times after administration were all fewer than those in the saline group (20.2±10.8, 14.5±7.6, 7.6±4.5,50.6±15.5, P < 0.01), and the analgesic effects of CNL extract were dosedependently. ② Time for the pain response induced by hot plate: 0.10 and 0.20 mg/g CNL extracts had significant analgesic effects on the pain in duced by hot plate, and the time for pain sensation at 15, 30 and 60 minutes after administration were all longer than those in the saline group (P < 0.05 or P < 0.01), and the analgesic effect was dose-dependently. The times for pain sensation at each time point after administration in the naloxone 0.004 mg/g+CNL extract 0.01 mg/g group were all longer than those in the saline group, but those were close between the naloxone 0.004 mg/g+morphine 0.01 mg/g group and the saline group. ③ Analgesic rate induced by electrostimulation in the mice: The analgesic rates at20, 35, 50 and 70minutes after administration in the CNL extract 0.10 and 0.20 mg/g groups were all higher than those in the saline group (P < 0.01).CONCLUSION: Our data suggested that CNL extract has obvious analgesic effect, and the analgesic intensity is dose-dependently. Naloxone, an opiate receptor antagonist, can antagonize the analgesic effect of morphine,but cannot antagonize that of CNL extract on mice with pain induced by hot plate, which indicates that CNL extract exert its analgesic role not through binding with opiate receptor.

Objective To explore the effects and related mechanism of Exendin-4 on secretion of extracellular matrix in high glucose-induced glomerular mesangial cells(GMCs). Methods GMCs were incubated in medium with glucose or Exendin-4 for the four groups: normal glucose group(NG group): cells were treated in medium with 5.6 mmol/L glucose; NG with Exendin-4 treatment group(NGE group): cells were treated with 5.6 mmol/L glucose and Exendin-4; high glucose group(HG group): cells were cultured with 30 mmol/L glucose; HG with Exendin-4 treatment group(HGE group): cells were treated with 30 mmol/L glucose and Exendin-4 at concentration of 3, 5, 10, 15, 30 nmol/L separately, which were cultured for 12, 24, 48 hours. GMCs treated with Exendin-4 were determined by assessing proliferation using a CCK8 method. The levels of fibronectin(FN), collagen type Ⅳ(Col-Ⅳ)in the cell supernatant were measured using enzyme-linked immunosorbent assay(ELISA). The gene levels of Col-Ⅳ, FN, and expression of inflammatory mediators including monocyte chemotactic protein 1(MCP-1), tumor necrosis factor-α(TNF-α), intercellular cell adhesion molecule-1(ICAM-1), transforming growth factor-β1(TGF-β1)were evaluated using reverse transcription PCR(RT-PCR); The expression of nuclear transcription factor-κB(NF-κB), glucagon-like peptide-l receptor(GLP-1R), and phosphorylation levels of mitogen-activated protein kinases(MAPKs)were evaluated by Western blot. Results(1)After treatment with 10 nmol/L Exendin-4 for 24 hour, the proliferation rate of GMCs was significantly decreased compared with 3 nmol/L, 5 nmol/L Exendin-4 treatment(P<0.05), while there was no difference compared with 15 nmol/L, 30 nmol/L Exendin-4 treatment(both P>0.05). (2)The gene expression of FN, Col-Ⅳ and the inflammatory mediators, MCP-1, TNF-α, ICAM-1, TGF-β1 in HG group were significantly increased compared with the NG group,(all P<0.05). After treatment with Exendin-4, the levels of FN, Col-Ⅳ and the gene expression of TNF-α, MCP-1, ICAM-1, TGF-β1 were decreased(all P<0.05). (3)Compared with NG group, the expression of NF-κB and the phosphorylation of extracellular regulated protein kinases(p-Erk1/2), Jun N-terminal kinase(p-JNK)and, p38MAPK(p-p38MAPK)in the group of HG group were increased significantly, accompanied by the decrease of GLP-1R protein level(all P<0.05). Importantly, Exendin-4 treatment significantly reduced protein expression of p-Erk1/2, p-JNK, and NF-κB(all P<0.05), and the level of GLP-1R protein increased(P<0.05). Furthermore, specific Erk1/2, JNK or NF-κB inhibitors markedly blocked Exendin-4-mediated decrease in the levels of FN, Col-Ⅳ. Conclusion Exendin-4 treatment inhibits the secretion of extracellular matrix potentially through Erk1/2, JNK/NF-κB signaling in higher glucose induced GMCs.

objective To investigate preoperative donor and recipient assessment,choice of surgical options in living donor liver transplantation(LDLT).Methods The clinical data of 95 patients who underwent LDLT from January 1995 to October 2007 in our center were retrospectively analyzed.Of all,92 recipients were benign end-stage liver disease patients (including 45 patients with Wilson disease),and 3 were malignant hepatic carcinbma patients.Results Thirty-one fight lobes without middle hepatic vein(MHV),3 right lobes with MHV,51 left lobes with MHV.and 10 left lobes or left lateral lobes without MHV were obtained.All the donors recovered after operation. Recipients with benign end-stage liver disease were followed up for 1 to 86 months,and the 1-,3-,5-year accumulative survival rates were 89%(82 cases),78%(71 cases)and 73%(67 cases),respectively. The 1-,3-,5-year survival rates of patients with Wilson disease were 92%(42 cases),89%(40 cases)and 76%(34 cases),respectively. For the 3 patients with malignant hepatic carcinoma,2 died and 1 was alive and well. The copper metabolism was back to normal in both donors and recipients. Conclusions Establishment of a system for the safety of donors is basic for LDLT. The key to raise the recipients' survival rates is to choose the optimal surgical approach. LDLT is effective in treating Wilson disease.
