Objective To study the effect of transfection of livin antisense oligodeoxynucleotide (Livin ASODN) on Livin mRNA and Livin protein expression and proliferation of QBC939 cells.Methods Livin ASODN was transfected into cell line QBC939 by LipofectamineTM 2000. Fluorescence microscopy was used to observe the ASODN transfected cells and to calculate the rate of transfection.to measure Livin mRNA and Livin protein expression by RT-PCR and immunohistochemistry and con-focal laser scanning microscopy after the transfection. Changes in cell proliferation were detected by MTT. Results The highest efficiency was at 24 hours after 500 nmol/L Livin ASODN transfection.The results of MTT showed that the inhibition of cell proliferation of QBC939 cells was most obvious at 60 hours after Livin ASODN transfection (P<0. 05). The level of Livin mRNA and Livin protein expression in the ASODN group was obviously lower than that in the control group (P<0. 05).Conclusion The transfection of Livin ASODN inhibited Livin gene and Livin protein expression, and obviously inhibited the proliferation and depressed the vitality of QBC939 cells.

ObjectiveTo observe the clinical efficacy ofTong Du Tiao Shen(unblocking the Governor Vessel and regulating spirit) needling method plus Nimodipine in treating vascular dementia.MethodSixty patients with vascular dementia were randomized into a treatment group and a control group, 30 in each group. The control group was intervened by oral administrationof Nimodipine, while the treatment group was additionally intervened byTong Du Tiao Shenneedling method. Two weeks were taken asa treatment course, and the intervention lasted 2 courses. The Mini-Mental State Examination (MMSE) and Activities of Daily Life (ADL) were evaluated and compared before and after intervention, and the therapeutic efficacy was determined.Result After intervention, there were significant differences in comparing MMSE and ADL scores between the two groups (P<0.05). ConclusionTong Du Tiao Shenneedling method plus Nimodipine is effective in treating vascular dementia, and worth promotion in clinic.

Objective To analysis the effect of conbercept ophthalmic injection on peripheral blood vascular endothelial growth factor,intraocular pressure and visual acuity in patients with age related macular degeneration.Methods 60 patients who were diagnosed with age related macular degeneration were collected.All patients were randomly divided into experimental group and control group,30 cases in each group, lucentis intravitreal injection was given into the vitreous cavity in control group, experimental group give conbercept injection into the vitreous cavity,once a month.All patients were treated for 3 months,after the end of treatment,all patients serum VEGF and CRP,CMT,CNV and fluorescence leakage rate,intraocular pressure and visual acuity were detected.ResuIts After treatment,compared with control group,the content of serum VEGF was significantly lower in the experimental group(P<0.05).The content of serum CRP was significantly lower in experimental group(P<0.05).The CMT,CNV and fluorescence leakage rate were significantly lower in the experimental group (P<0.05).The level of IOP and visual acuity(logMAR)were significantly lower in the experimental group (P<0.05).ConcIusions Conbercept ophthalmic injection can reduce age-related macular degeneration patients week blood VEGF and CRP levels and decrease the CMT, CNV and fluorescence leakage rate, reduce intraocular pressure, visual acuity improvement and have guiding significance for clinic.
