To investigate the herbal medicines which play a main role in Chinese herbal formula Jianpi Huoxue Decoction for improving intestinal permeability and protect alcohol-induced liver injury and intestine damage, and to explore the analysis method for the material base of pharmacological effects of the Chinese herbal compound.

OBJECTIVE: To observe the effects of Jianpi Huoxue Decoction, a compound Chinese herbal medicine, on Kupffer cell signal pathway activation in rats with liver injury induced by Lieber-Decarli liquid diet and lipopolysaccharide (LPS). METHODS: SD rats were divided into normal, control liquid diet, ethanol liquid diet and ethanol liquid diet plus Jianpi Huoxue Decoction group. Rats were administrated with Jianpi Huoxue Decoction or distilled water via gastrogavage for 4 weeks after administration with ethanol or control liquid diet for 2 weeks respectively. After that, rats in each group were stimulated with LPS via gastrogavage for 3.5 h and harvested. Alanine aminotransferase (ALT) in serum and triglyceride (TG) in liver were analyzed. Pathological changes in liver tissues were observed in HE staining section. Tumor necrosis factor-alpha(TNF-alpha) in portal vein plasma was assayed by ELISA. The protein expressions of CD68, Toll-like receptor 4 (TLR4), phosphorylation-I kappa B (P-I kappa B) and TNF-alpha in liver were evaluated with Western-blotting. RESULTS: After the treatment with Jianpi Huoxue Decoction, the pathologic changes in liver tissue were lightened, levels of ALT in serum, TG in liver and TNF-alpha in portal vein plasma were decreased, and the protein expressions of CD68, TLR4, P-IkappaB and TNF-alpha in liver were reduced. CONCLUSION: Jianpi Huoxue Decoction can inhibit Kupffer cell signal pathway activation in rats with liver injury induced by Lieber-Decarli liquid diet and LPS.

OBJECTIVE: Duplicating the classical alcoholic hepatic injury model, to provide an ideal animal model for research on prevention and treatment of hepatic injury. METHODS: According to the prescription of Lieber-DeCarli, the same calorie fluid animal feed, which contained ethanol or non-ethanol, was prepared. Twenty-three rats were divided into normal control group (n=5), control liquid diet group (n=9), ethanol liquid diet group (n=9). Rats in the normal control group were fed normal diet, and rats in the control liquid diet group and ethanol liquid diet group were fed the corresponding diet for eight weeks. The pathologic changes of hepatic tissue were observed. The activities of the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), the liver tissue gamma-glutamyltransferase (gamma-GT), the content of triglyceride (TG), and the lipid peroxidation by-products were assayed. RESULTS: Compared to the normal control and the control liquid diet groups, the activities of ALT, AST, and gamma-GT, and the lipid peroxidation by-products increased significantly in the ethanol liquid diet group. The pathological changes of cellular swelling and fatty degeneration in the ethanol liquid diet group were severe. CONCLUSION: Alcoholic hepatic injury model can be successfully duplicated by Lieber-DeCarli prescription.

Objective:o prepare Danshensu liposomes and investigate drug release characteristics in vitro. Methods: Danshensu liposomes were prepared by a reverse-phase evaporation method. The encapsulation efficiency was used as the index, an orthogonal test was adopted to investigate the effect of concentration of soybean lecithin, ratio of lipid-Danshensu and pH value of solution on the preparation procedure of Danshensu liposomes. The particle size of the liposomes was also investigated by a transmission electron micro-scope ( TEM) . The concentration of Danshensu was determined by HPLC, and the difference of release characteristics in Danshensu li-posomes and Danshensu solution was measured by a dialysis method. Results:The optimum preparation technology was as follows:the concentration of soybean lecithin was 40 mg·ml-1 ,the ratio of drug-lipid was 1: 10,and the pH value of solution was 6. 6. The mor-phology of the prepared liposomes showed spheric structure with uniform diameter, and the average particle size was ( 174 ± 36 ) nm and the encapsulation efficiency was 38. 9%. The linear range of Danshensu was 2. 0-20. 0 mg·L-1(r=0. 9984). The drug release of liposomes in vitro was slower than that of free Danshensu solution in 24 h. Conclusion:Danshensu liposomes with fine morphology have sustained release property.

OBJECTIVE: To investigate the effects of Fuzheng Huayu Recipe on renal interstitial fibrosis in rats induced by the toxic substances. METHODS: Forty Wistar rats were divided into 3 groups, including the normal group, model control and Fuzheng Huayu Recipe treated group. The renal fibrotic model was induced with intraperitoneal injection of dimethylnitrosamine (DMN) for 4 weeks and oral administration of food containing heavy metals such as Hg, etc for 8 weeks. From the 5th week, the rats were orally administered Fuzheng Huayu Recipe for 4 weeks. The renal tissue was stained with HE and periodic acid-silver metheramine, respectively. The serum creatinine and urea nitrogen were assayed with the kits, and the renal hydroxyproline (Hyp) contents in the homogenate of kidney tissue were measured with HCl hydrolysis. RESULTS: In the model group, the renal tubule was swollen, and the tubular epithelial cells were degenerated, necrosed and detached, with the infiltration of inflammatory cells; the tubular interstitium was expanded, characterized with the deposition of large collagens; the tubular basement membrane became thicker and wrinkled; and the renal Hyp content and serum creatinine and urea nitrogen levels increased remarkably as compared to the normal group. After the treatment with Fuzheng Huayu Recipe, the renal tubular inflammation and interstitial collagen deposition were alleviated, and the serum creatinine and urea nitrogen levels decreased significantly as compared to the model group. CONCLUSION: Administration of DMN and heavy metals can induce the renal interstitial fibrosis and impair the renal function. Fuzheng Huayu Recipe can improve the impaired renal functions and reverse the renal interstitial fibrosis.

OBJECTIVETo evaluate the efficacy and safety of autologous cytokine-induced killer (CIK) cell t combined with XELOX regimen in treatment of senile advanced gastric cancer.

METHODSForty-six cases of senile advanced gastric cancer patients with a mean age of 70 years were prospectively divided into two groups according to individual acceptance of CIK cells: 25 patients receiving autologous CIK cell treatment combined with XELOX regimen (trial group) and 21 patients receiving simple chemotherapy (control group). Patients in CIK group were matched to those in control group by sex, ages, KPS ranking scores, histological type, pathological grade, and clinical stage. Immune reaction, adverse reaction, time to progression (TTP) and overall survival (OS) were evaluated.

RESULTSHost immune function was increased (P<0.05) and the adverse reaction was decreased in patients of trial group as compared to control group. There were no significant differences in response rate (RR)(33.3% vs. 23.1%, P>0.05), disease control rate (DCR)(86.7% vs. 80.8%, P>0.05) between the two groups. TTP (4.8 months vs. 3.1 months, P<0.05) and OS (7.1 months vs. 5.9 months, P<0.05) in trial group were significantly improved as compared to control group.

CONCLUSIONAutologous CIK cells combined with XELOX regimen can increase immune function, improve clinical efficacy, decrease adverse reaction and prolong OS for senile patients with advanced gastric cancers.
