Objective:To compare the pharmacokinetics and relative bioavailability between matrine sustained release tablet,matrine conventional capsule and matrine injection. Methods: Dogs were given single oral dose and multiple doses of matrine sustained release tablet, capsule or injection in a randomized crossover way. Matrine concentrations in dog plasma were determined by RP-HPLC method. Results: The results showed that the t max and c max were 300 min and (5.088?0.490) ?g/ml for matrine sustained release tablet, (85?12) min and (6.360?0.215) ?g/ml for the conventional capsule, and 10 min and (6.500?0.404) ?g/ml for the injection. The relative bioavailability of the sustained release tablet was (153.7?9.4)% compared with that of the conventional capsule; the absolute bioavailability of the sustained release tablet was (73.5?14.2)% compared with that of the injecetion. The in vivo absorption rate of the sustained release tablet was significantly correlated with the in vitro release rate(r=0.981 2,P

To investigate the relationship of the variation of virulence and the external capsid proteins of the pandemic duck hepatitis A virus type 1(DHAV-1) isolates,the virulence,cross neutralization assays and the complete sequence of the virion protein 1(VP1) gene of nine virulent DHAV-1 strains,which were isolated from infected ducklings with clinical symptoms in Shandong province of China in 2007-2008,were tested.The fifth generation duck embryo allantoic liquids of the 9 isolates were tested on 12-day-old duck embryos and on 7-day-old ducklings for the median embryonal lethal doses(ELD50s) and the median lethal doses(LD50s),respectively.The results showed that the ELD5s of embryonic duck eggs of the 9 DHAV-1 isolates were between 1.9 × 106/mL to 1.44 × 107/mL,while the LD50s were 2.39 × 105/mL to 6.15 × 106/mL.Cross-neutralization tests revealed that the 9 DHAV-1 isolates were completely neutralized by the standard serum and the hyperimmune sera against the 9 DHAV-1 isolates,respectively.Compared with other virulent,moderate virulent,attenuated vaccine and mild strains,the VP1 genes of the 9 strains shared 89.8％-99.7％ similarity at the nucleotide level and 92.4％-99.6％ at amino acid level with other DHAV-1 strains.There were three hypervariable regions at the C-terminus(as 158-160,180-193 and 205-219) and other variable points in VPI protein,but which didn't cause virulence of DHAV-1 change.

Objective To investigate the potential role of Lycium bararum polysaccharide (LBP) with or without interferon -inducible protein 10 ( CXCL10) in inducing dendritic cells ( DC) functional maturation by monitoring the alteration of cytokines for inducing DC maturation in peripheral blood and by detecting the expression of S-100 protein in tumor tissue, thus to reveal its mechanism of inhibiting experimental liver cancer. Methods H22 bearing mice model was established. The mice were randomized into model group, LBP group (50 mg/kg, ig), CXCL10 (right axillary subcutaneous injection of 15 μg/kg), LBP + CXCL10 group (LBP 50 mg/kg, ig, and right axillary subcutaneous injection of CXCL10 15 μg/kg), 5- fluorouracil (5FU) group ( intraperitoneal injection of 12mg/kg) , 12 mice in each group. The mice were administered the corresponding medicine once a day. After treatment for 2 continuous weeks, blood was sampled from infraorbital vein, and the tumor mass, spleen, thymus were extracted for the calculation of anti-tumor rate, thymus index and spleen index separately . The mRNA expression levels of interleukin 12 (IL-12) and tumor necrosis factor-α (TNF-α) in peripheral blood were detected by fluorescence quantitative PCR, the expression of S-100 protein in tumor tissues was detected by immunohistochemical assay. Results Compared with the model group, tumor growth in LBP group and LBP+CXCL10 group was obviously inhibited, and tumor-inhibitory rate was 55.90%, 50.91%, respectively. Meanwhile, the mRNA expression level of IL-12 was 2.94 folds higher in LBP group and 3.39 folds higher in LBP + CXCL10 group, and TNF-α mRNA expression level was 1.55 folds higher in LBP group and 4.74 folds higher in LBP+CXCL10 group than the model group, the differences being statistical significant ( P<0.05 or P<0.01). Results of immunohistochemical assay showed that S-100+DC number in LBP group and LBP+CXCL10 group was larger than that in the model group (P<0.05 ). Conclusion LBP and LBP+CXCL10 exert significant effect on inhibiting experimental liver cancer. The mechanism may be related with inducing the secretion of IL-12 and TNF-α, which plays a key role in inducing DC maturation, and with the increase of the number of DC in tumor microenvironment.

Objective To investigate the prevalence of nutritional risk,malnutrition(undemutrition),overweight/obesity,and application of nutritional support in hospitalized patients with endocrine disorders.Methods Adult patients in Department of Endocrine of Peking Union Medical College Hospital(PUMCH)from September to December 2008 were consecutively enrolled.Nutrional Risk Screening 2002(NRS2002)war per-formed on the next morning after admission and nutritional support evaluation was performed on the 14th day of ad-mission or on the discharge day.The relationship between nutritional risk and nutritional support Was analyzed.Nu-tritional risk was defined as NRS2002 score≥3,and body mass index(BMI)<18.5 ks/m2 defined as unclernut-rition.Results A total of 152 patients were enroled,and NBS2002 scoring was performed in all patients.The prevalence of undernutrition Was 7.9%and the nutritional risk was 27.6%.The prevalence of nutritional risk in the elderly inpotients(≥60 years old)was significantly higher than in younger patients(18-59 years old)(36.8%vs 20.2%,P=O.023).Nine patients(21.4%)with NRS2002≥3 received nutrition support,and 12patients(10.9%)with NRS2002<3 received nutritional support.The average PN:EN ratio was 1:3.2.Conclu-siom NRS2002 is afeasible nutritional risk screening tool for inpatients with endocrine disorders.A large propor-tion of inpotients were at nutritional risk or undemutrition in the Department of Endocrine of PUMCH. The application of nutritional support currently is somehow inappropriate.Evidence-based guidelines are required to improve this situation

Objective To investigate the effect of serum of esophageal squamous cell carcinoma (ESCC) patients with blood stasis syndrome (BSS) on proliferation and cycle of EC9706 cells, and to explore the action of blood micro-environment of ESCC patient with BSS on EC9706 cells. Methods Human EC9706 cells were cultured in an incubator with RPMI-1640 medium containing fetal bovine serum ( FBS) , at 37℃ and under 5% saturated humidity for 24 h. After EC9706 cells were starved in serum-free medium for another 24h, the three experimental groups were treated with serum of ESCC patients with BSS, serum of ESCC patients with spleen-qi deficiency syndrome (SQDS), and serum from healthy volunteers, respectively. Cell proliferation was determined by methyl thiazolyl tetrazolium ( MTT) assay, EC9706 cell morphology was observed under light microscope, and cell cycle was measured by flow cytometer (FCM). Results The serum concentrations of ESCC patients with BSS and ESCC patients with SQDS for obtaining 50 percent cell proliferation rates ( PI50) were 71.1 μL/mL and 118 μL/mL, respectively. And the proliferation of EC9706 cells in the both groups all arrived to the peak values at culturing hour 48. The light microscopy results showed that the feature of EC9706 cells in both groups presented as spindle-like or polygon-like shape, and cell count in BSS group was larger than SQDS group. FCM assay results for EC9706 cell cycle showed that the percentage of G1-phase EC9706 was decreased and the percentage of S-phase EC9706 was increased in BSS group as compared with those in SQDS group ( P<0.05). Conclusion Serum micro -environment in ESCC patients with BSS is more beneficial to EC9706 cells proliferation than ESCC patients with SQDS, and the mechanism may be related to the regulation of cell cycle.
