Objective To study the preventive and therapeutic effects and the mechanism of Chinese traditional compound medicine to subcilincal hepatic encephalopathy(SHE)induced by endotoxin in liver cirrhotic rats.Methods The liver cirrhosis model of rats were made in subcutaneous injection of 40% carbon tetrachloride,the SHE model was made by infused with endotoxin into the tail vein.Treatment group was given low dose or moderate dose or high dose of Chinese traditional compound medicine,Control group was treated with lactulose.The morbidity of SHE,hepatic function,blood ammonium(BA),endotoxin,liver tissue pathology were observed.Results Above indexes were improved by every group of Chinese traditional compound medicine.The curative effect of moderate and high group of Chinese traditional compound medicine to the hepatic function,BA,endotoxin,liver tissue pathology were better than that of lactulose.Conclusions The effects of the Chinese traditional compound medicines(compose of Polygonum cuspidatum,raw hawthornfruit,seed of Zizyphus jujuba Mill,Mongolian Dandelion Herb and Rhizoma Acoori Graminei)in SHE prevention and treatment is significant.Its mechanism might be as follows:① recovering liver function,decreasing inflammatory changes of liver tissue;② preventing the absorption of BA,lowering the content of BA;③ reducing the sensitivity of the body to endotoxin.

Objective:To establish a method for the determination of zolpidemtartrate in human plasma by SPE-HPLC. Methods:The samples were extracted by solid phase with a Hypersil BDS C18 column and determined by an internal standard method. The mobile phase was methanol:acetonitrile:water (45 ∶45 ∶110), the flow rate was 1. 0 ml·min-1, the column temperature was 35℃, and the detection wavelength was 254nm. Results:The linear relationship of zolpidemtartrate was within the range of 0. 511 5-4. 092 0 μg· ml-1 . The relative recovery was greater than 90%. The intra-and inter-day RSDs were all less than 10%. Conclusion:The method is quite simple, quick and accurate with little interference, which is suitable for the clinical determination of zolpidemtartrate.

Objective To observe the therapeutic effects of Chinese traditional compound medicine on subcilincal hepatic encephalopathy(SHE).Methods 52 patients with liver cirrhosis complicated by SHE were randomly divided into treatment group and control group.The patients of control group received conventional hepatoprotection treatment,and the patients of treatment group were given conventional treatment and Chinese traditional compound medicines.Number connection test(NCT),electroencephalogram(EEG),liver function,blood ammonia were investigated after 2 weeks of treatment.Results The number connection test (NCT),electroencephalogram (EEG),liver function,blood ammonia were significantly improved in the treatment group than that in the control group(P

Objective: To explore the high dose atorvastatin reducing contrast induced nephropathy (CIN) rate in patiens with emergent percutaneous coronary intervention (PCI) via improveing heat shock protein-90 (HSP90) expression with its possible mechanism. Methods: A total of 158 STEMI patients with emergent PCI in our hospital were studied. The patients were randomly divided into 2 groups: High dose atorvastatin group, the patients received pre-operative atorvastatin 40 mg,n=80 and Control group, the patients received pre-operative placebo,n=78. The serum creatinin (Scr), creatinine clearance rate (Ccr), blood urea nitrogen (BUN), superoxide dismutase (SOD), malondialdehyde (MDA), nitrogen monoxide (NO), HSP90 mRNA expression and protein concentration and urine α1-microglobulin were examined in all patients and the incidence rates of CIN were compared between 2 groups. Results: Compared with Control group, High dose atorvastatin group had drcreased Scr (68.92 ± 8.80) μmol/L vs (77.25 ± 13.36) μmol/L, MDA (3.88 ± 0.53) nmol/L vs (4.08 ± 0.52) nmol/L and urine α1-micrglobulin (1.38 ± 0.36) mg/dl vs (1.89 ± 1.13 ) mg/dl; increased Ccr (89.71 ± 9.85) ml/min vs (77.28 ± 13.78) ml/ min, SOD (129.52 ± 30.63) U/ml vs (117.66 ± 27.98) U/ml, NO (66.23 ± 29.26) μmol?gprot vs (55.12±27.43) μmol?gprot, allP<0.05. Compared with Control group, High dose atorvastatin group presented higher post-operative HSP90 mRNA expression (0.466 ± 0.158) vs (0.224 ± 0.278 ) and protein concentration (1259.83 ± 121.17) pg/ml vs (1195.0 ± 127.65) pg/ml, allP<0.05. The incidence rate of CIN was lower in High dose atorvastatin group (2.5%) than Control group (10.3%),P<0.05. Conclusion: A high dose atorvastatin administration before emergent PCI may decrease CIN occurrence rate. Atorvastatin may promote HSP90 expression, increase NO produciton, then improve the vascular endothelial function and anti-oxidative ability to protect the renal function in STEMI patients.

Objective To evaluate the association of Smad2/3,Smad4 and P-Smad3 protein expressions in tissue with liver fibrosis in patients with chronic HBV infections.Methods Liver biopsy was performed to determine the liver fibrosis grades in 131 cases of chronic HBV infections.Immunohistochemistry and semiquantitative analysis were applied to detect the expression of Smad2/3,Smad4 and P-Smad3 proteins in liver tissues.Results Smad2/3,Smad4 and P-Smad3 were detected mainly in fibrous septum,portal areas,myofibroblasts,sinus and cytoplasm in the liver tissue.The expression of Smad2/3,Smad4 and P-Smad3 was increased with the development of fibrosis ( r =0.81,0.58and 0.68,P =0.000),and a strong positive correlation was observed among three proteins (r =0.75,0.87and 0.84,P =0.000).Conclusion The expression of Smad2/3,Smad4 and P-Smad3 is correlated with liver fibrosis in chronic HBV infection,which suggests that the up-regulation of Smad proteins may be involved in the progression of liver fibrosis.

Method:The HPLC method was performed on an NOV-pak C18 (150 mm × 4. 6 mm, 5 μm) column and the mobile phase consisted of methanol and water (75∶25). The flow rate was 1. 0 ml·ml-1, the detection wavelength was 297nm, the temperature of column was 30℃ and the sample size was 20 μl. Result: The calibration curve of metronidazole was linear within the range of 5-80μg·ml-1(r=0. 999 7), and the average recovery was 100. 83% with RSD of 1. 82%(n=6). The cal-ibration curve of chlortalidone was linear within the range of 50-800μg·ml-1(r=0.999 7), and the average recovery was 100.2%with RSD of 0. 55%(n=6). Conclusion: The method is simple, rapid, accurate and reproducible, and can be used in the quality control of chlortalidone and metronidazole spirits.

Objective:To establish the method for determining nimesulide in thermo-sensitive hydrogels and study the stability of the preparation. Methods:An HPLC method was adopted with a Shim-Pack C18-ODS (150 mm × 4. 6 mm,5 μm) column, the mobile phase was composed of menthol-water-acetic acid (65∶35∶0. 8) with the flow rate of 1. 0 ml·min-1 at 30℃, the detection wavelength was at 299 nm, and the injection volume was 10 μl. Results:The separation of nimesulide, impurities and degradation products was good. The linear range of nimesulide was 2. 43-24. 37μg·ml-1(r=0. 999 8), the average recovery was 100. 02%(RSD=1. 12%, n=5). The lowest detectable limit and the lowest quantitation limit was 0. 098μg·ml-1 and 0. 25μg·ml-1, respectively. The stabil-ity results of hard-light exposure, destructive testing and long-term testing showed that the preparation was basically stable at room tem-perature, while under high temperature with hard light, strong basicity, acidicity or oxidation solution, the preparation was unstable. Conclusion:The method is accurate and reliable in the determination and stability study of nimesulide thermo-sensitive hydrogels. The hydrogels should be stored in shady, cool and dark place.
