Objective: To explore the effects of ranitidine on pharmacokinetics of rhein in rats after oral administration of Dachengqi Decoction (DCQD), a compound traditional Chinese herbal medicine. Methods: Twelve male Sprague-Dawley rats were divided into DCQD group and DCQD plus ranitidine group, and were orally administered with DCQD at a dose of 10 g/kg or DCQD (10 g/kg) combined with ranitidine (150 mg/kg), respectively. Blood samples were gathered after a series of time intervals. Metabolism of rhein was determined with a reversed-phase high-performance liquid chromatography with internal standard of 1, 8-dihydroxyanthraquinone and the data were analyzed with DAS 2.1 program. The pharmacokinetic parameters were compared between the two groups. Results: The pharmacokinetic parameters of rhein in the DCQD group, including peak concentration (C(max)), area under the plasma concentration-time curve (AUC), distribution phase half-life (t(1/2alpha)), elimination rate constant (K(10)) and central to peripheral transfer rate constant (K(12)), were significantly different to those in the DCQD plus ranitidine group (P<0.05, P<0.01). There were no significant differences in the other parameters between the two groups. Conclusion: Ranitidine can influence the pharmacokinetics of rhein in rats after oral administration of DCQD.

Objective To investigate the effect of soybean isoflavone on histology and uhrastructure of benign prostatic hyperplasia in rats.Methods Male SD rats were injected subcutaneously testosterone propionate for 28 d to induce prostatic hyperplasia,and the rats were divided into 5 groups:control group,model group,and 3 test groups with SI in a dose of 60 mg/(kg·d),120 mg/(kg·d) and 240 mg/(kg·d),respectively.The wet prostate weight,prostatic index,morphological,uhrastmetural and morphometrie changes of the prostatic shndular and interstitial tissues were observed.Results The prostate wet weight,prostatic index and prostatic volumes in all dose groups were significantly lower than those in the models.In comparison with the model group,height of prostatic epithelial cells,glandular average diameters,volumes and surface areas in unit volume,as well as glandular circumferences,glandular relative total volumes and interstitial relative total volumes were all significantly decreased.Glandular counts,density,ratio of glandular surface area to volume,and glandular average curvature were all increased.Conclusions Soybean isoflavone can inhibit prostatic hyperplasia in rats.

Objective To investigate the effects of Pseudomonas aeruginosa vaccine (PA) on proliferation and invasiveness of the hepatocellular carcinoma cell line MHCC97L with metastatic potential. Methods Proliferation, growth curve, plate efficiency, flow cytometry, transwell invasion assay, cell motility assay, scarification test, vascular endothelial growth factor (VEGF) and matrix metalloproteinase-2 (MMP2) protein activity were evaluated after cells were treated with PA at various concentrations. Results PA can inhibit the proliferation and plate efficiency of MHCC97L cell markedly in a dose-dependent manner. The IC50 of cells treated with PA for 48 h and 72 h was 3.1 ×108/ml and 1.9 × 108/ml, respectively. The doubling time increased and plate efficiency decreased gradually when cells treated with 0.5 × 108/ml, 1 × 108/ml and 2 × 108/ml PA (P<0.01). PA could induce cell cycle arrest at the G1 phase in a dose-dependent manner by flow cytometric analysis. The average amount of invading cell per field in cell invasion assay and motility assay were 4. 8 ± 1.3 and 8. 8±2.2 when cells treated with 1× 108/ml PA, which was significantly lower than that of control group (8. 6±2. 1 and 15. 6±1.2 ) (P<0.01) Scarification test showed that the metastatic ability of cells treated with 1 × 108/ml PA significantly lower than that in the control group. Comparison between cells treated with 1 × 108/ml PA and control group, no remarkable difference was found regarding expression of VEGF and MMP2 in supernatant of cell culture. Conclusion PA can inhibit proliferation and plate efficiency of HCC cell line MHCC97L, which is in part mediated by the cell cycle arrest at the G1 phase. PA could inhibit invasiveness of HCC cell line MHCC97L, which is unrelated to the VEGF and MMP2 protein activity.

Objective To study the change of the renal endogenous hydrogen sulfide (H2 S) pathway in the development of salt-sensitive hypertension in Dah1 rats.Methods Sixteen male Dah1 rats,in accordance with the random number table,were randomly divided into control group and high salt group fed with diet containing 80 g/kg NaCl.After 8 weeks,24 h urine sodium,24 h urinary protein,serum creatinine and serum urea were measured.The microstructural and ultrastructural changes in kidney were observed with light microscope and electronic microscope.The serum and kidney H2S contents were determined by using sulphur-sensitive electrode method.The mRNA levels of cystathionine β-synthase(CBS),cystathionine γ-lyase(CSE) and mercaptopyruvate sulfurtransferase(MPST) in renal tissue were determined by means of real-time polymerase chain reaction(RT-PCR).The protein expressions of CBS,CSE and MPST in renal tissue were detected by using Western blot.Results Compared with control group,high salt group rats had a significant rise in blood pressure,declined renal function,damaged renal structure,segmental glomerular sclero sis,small artery wall thickening,and occlusion of the lumen.Moreover,the endogenous H2S pathway in kidney of Dah1rats with high salt diet was downregulated markedly,demonstrated by the decreased serum and kidney H2S content,the reduced renal CBS,CSE and MPST mRNA expressions and CBS protein expression of kidney tissue.Conclusion The endogenous H2S/CBS pathway is downregulated during the development of salt-sensitive hypertension in Dah1 rats.

BACKGROUND:At present, col agen as a material in periodontal tissue engineering has some disadvantages such as poor mechanical strength and rapid degradation speed. Col agen combined with chitosan can improve above-mentioned problems.
OBJECTIVE:To evaluate the biocompatibility of a novel chitosan-col agen scaffold in vitro.
METHODS:Cytotoxicity of the extract of chitosan-col agen scaffold in different concentrations (100%, 75%, 50%, 25%) was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Human periodontal ligament cel s at 4-6 passages were cocultured with the chitosan-col agen scaffold. Cel growth on the scaffold was observed. Changes in alkaline phosphatase activity were detected in periodontal ligament cel s before and after coculture.
RESULTS AND CONCLUSION:The novel chitosan-col agen scaffold was made up of double layers with one dense layer and another loose layer. The grade of the cytotoxicity of the scaffold was from 0 to 1. Scanning electron microscope and histological observation demonstrated that cel s grew wel on the chitosan-col agen scaffold;the dense layer could prevent cel s to migrate into the scaffold. There were no significant differences in alkaline phosphatase activity in human periodontal ligament cel s before and 24 hours after combined culture (P>0.05). Alkaline phosphatase activity in human periodontal ligament cel s was greatly higher at 48 and 72 hours after combined culture compared with that before culture (P<0.05). Above results indicated that the novel chitosan-col agen scaffold has a good biocompatibility and barrier function, and potential as a scaffold for periodontal tissue engineering.
