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.

avian influenza virus (AIV) can not only infect avian and cause pandemics,but also result infection and initiate pandemics in humans and other mammal animals,crossing the species barrier.There have been some advance in research into the nonspecific species barrier of human respiratory tract against AIV infection and the mechanism of the infection of AIV in humans in recent years.

Objective:To observe the clinical effect of tuina plus foot bath with Chinese medicine for patients with diabetic foot (DF) in early stage.Methods:A total of 70 patients with early-stage DF were randomly allocated by the random number table into two groups,with 35 cases in each group.Patients in the control group received conventional medication,while patients in the observation group received tuina plus foot bath with Chinese medicine on the basis of conventional medication.The clinical efficacy was compared after 2 courses of treatment.Results:After treatment,intra-group comparisons of ankle-brachial index (ABI) showed statistical significance in both groups (both P＜0.05).The curative rate was 83.3％ in the observation group,with the total effective rate of 96.7％,versus 29.4％ and 76.5％ in the control group,respectively,and the between-group comparisons showed statistical significance (both P＜0.05),indicating a better effect in the observation group.Conclusion:Tuina plus foot bath with Chinese medicine has a good therapeutic effect for DF patients in early stage.

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.
