Objective:To comparatively observe the effects of 20(R)-ginsenoside Rg3 and PEG-PLGA-Rg3 nanoparticles on the Lewis lung cancer mice and to explore the mechanisms of Rg3 and PEG-PLGA-Rg3 nanoparticle anti-cancer in vivo.Methods:Lewis lung cancer mouse model was established and 60 mice were randomly divided into 5 groups with twelve in each group:PEG-PLGA-Rg3 nanoparticles group (Rg3-N),PEG-PLGA group (PEG),Rg3 group (Rg3 ),normal control group (C),saline control group(NS),and received intragastric administration for 1 4 days.The weights of the mice were measured every 2 days and the weight curves were obtained.At the same time,the color pattern,activity and men-tal status were observed.The mice were sacrificed when the administration was over,and the effects of 20 (R)-ginsenoside Rg3 and PEG-PLGA-Rg3 nanoparticles on tumor weight,and the tumor:weight ratios were analysed.In addition,the tumor microvessel density (MVD)was measured by immunohistochemi-cal staining with anti-CD31 antibody to compare the effects of Rg3 and PEG-PLGA-Rg3 nanoparticles on the tumor angiogenesis in vivo.Furthermore,the levels of such angiogenesis and proliferation factors as MMP-9,HIF-1 α,VEGF,Ki-67 were examined by RT-PCR,Western blot and immunohistochemistry to explore the internal molecular mechanisms of anti-tumor effects in vivo.Results:The trends of variation of the mice weights in NS group and PEG group were rising early but declining later.In contrast,the trends of the other three groups were rising early and became stable later.In comparison with NS group, the mice of Rg3 group and Rg3-N group had better general status:brighter color,more active and better spirit.Compared with NS group,the tumor weight in PEG group,Rg3 group and Rg3-N group showed no significant difference but the tumor:weight ratio and MVD in Rg3 group and Rg3-N group declined signi-ficantly (P <0.01 ).Besides,there was no significant difference between Rg3 group and Rg3-N group. At the same time,the level of VEGF mRNA,the protein expression of MMP-9,HIF-1 α,VEGF in Rg3 group and Rg3-N group decreased compared with NS group.Furthermore,the level of each index above-mentioned in Rg3-N group was lower than that in Rg3 group.The expression of Ki-67 in PEG group,Rg3 group and Rg3-N group showed no significant difference compared with NS group.Conclusion:Rg3 and PEG-PLGA-Rg3 nanoparticle may suppress the expression of VEGF,MMP-9 and HIF-1 αin Lewis lung cancer mice,thereby indirectly contributing to their antitumor effects and alleviating the mice’s general status.In addition,PEG-PLGA nanoparticles embedding can promote Rg3 antitumor effect in vivo.

We describe two cases in which a forceps imprintdeveloped in the AcrySof ReSTOR IOL optic whileinserting these IOLs into the cartridge with straightclamping forceps. In case 1 ,the AcrySof ReSTOR IOL wasexplanted and observed under scanning electronmicroscopy (SEM). The SEM showed that the stepdesign of ReSTOR Multifocal IOL was well maintained. Incase 2, visual acuity, contrast sensitivity and wavefrontmeasurements were performed and no specific changeswere found. Strong evidence does not exist that suggeststhe on-axis forceps imprint can significantly compromisevisual acuity.

OBJECTIVE:To investigate the influence of TCM Granules of the detoxification and dissipation blood stasis formula Ⅱon fulminant hepatic mitochondrial lipid peroxidation in rats with hepatic failure.METHODS:The fulminant hepatic failure rat models were established by subcutaneous injection of thioacetamide (TAA).48 Wistar rats were randomly divided into 7 groups:blank control group,model group,low dose group,medium dose group,high dose group,the lactulose treatment group,and the "Bezoar pill for resurrection" treatment group.Intragastric administration was executed 3 d before model-making,twice per day with the interval of 12 hours.They were administered for 11times.12 hours after model establishment.MDA、SOD、CAT、GSH、NO and liver necrosis area in hepatic mitochondria were determined.RESULTS:The detoxification and dissipation blood stasis formula Ⅱcould notably reduce liver necrosis area and restrain produce of hepatic mitochondrial lipid peroxidatide MDA,retrieve the activity of SOD、CAT and increase the content of GSH,NO.Moreover it shows dose-effect relation.Compared with model group,there is statistical significance(P

Objective: To investigate the effects of different extracts of Smilax china L on the activity of ovarian cancer cells. Methods:Solvent extraction method was used to extract the active ingredients of Smilax china L. , and CCK-8 assay method was ap-plied to detect the influence of different Smilax china L. extracts (0, 50, 100, 150 and 200μg·ml-1 ) on the survival rate of ovarian cancer cells including low invasiveness A2780 cells and high invasiveness HO-8910PM cells. At the same time, the status of the two kinds of ovarian cancer cells at different time points (24, 48 and 72 h) was observed. Results:The IC50 of N-butanol extracts (SCR-B) on HO-8910 and A2780 ovarian cancer cells was 47. 5 μg· ml-1 and 69. 2 μg· ml-1 , respectively, and that of ethyl acetate ex-tracts (SCR-E) on A2780 and HO-8910 cells was 147. 9 μg· ml-1 and 166. 0 μg· ml-1, respectively. Smilax china L. extracts had the inhibition against both A278 and HO-8910PM ovarian cells in a dose-and time-dependent manner. Conclusion:The inhibitory activity of SCR-B against ovarian cancer cells is stronger than that of SCR-E, and SCR-B has stronger inhibition against A2780 cells than against HO-8910 cells. SCR-B has better inhibition against ovarian cancer cells.
