Objective To study the functional mechanism of Yougui Pill(Right Restoring Pill)through its effect on cerebral gene of mice models with kidney-yang asthenia caused by excessive physical and sexual activity.Methods There were 10,15,10 male mice in the control,model and treatment groups respectively.The control and model groups were treated with 0.5ml permouse perday distilled water by gavage while the treatment group was given 0.5ml permouse perday suspension of Yougui Pill.In the model and treatment groups,the ratio of male and female was 1∶6,feeding in the same cage,and the males were swimming everyday for 30~40 minutes,4 weeks in succession,to induce the kidney-yang asthenia.The 36K mouse cerebral gene chips were used to measure the brain genes of mice of 3 groups.The intensity ratio of fluorescence signals ≥2 and ≤0.5 were used as the scale to screen out the remarkably different genes.Results In the model and control groups,totally 186 gene with different expressions were screened out,including the 150 up-regulated genes and 36 down-regulated genes.In the treatment and model groups,155 gene with different expressions were screened out,including the up-regulated 64 genes and 91 down-regulated genes.There were 32 genes up-regulated in the model and control groups but down-regulated in the treatment and model groups,mainly involving the inflammation perimmunity and neurotransmissions persignal transduction genes.There were 12 genes down-regulated in the model and control groups but up-regulated in the treatment and model group,mainly involving the hormone related genes of melanin and orphan nuclear receptor.Conclusion Yougui Pill may make the notably down-regulated genes of melanin markedly up-regulated in mice models of kidney-yang asthenia,improving the effect of hormone related orphan nuclear receptor and promoting the cellular proliferation.

Age-related macular degeneration ( AMD ) is one of a leading worldwide cause of blindness. AMD is a multifactorial disease, and major risk factors include increasing age, current smoking, previous cataract surgery, environmental factors, nutritional factors, genetic markers through genetic regulate complement, lipid, angiogenesis and extracellular matrix. In addition to treatment, epidemiology, risk factors and genetics research of AMD have been significantly progressed. This article will review risk factors of AMD.

In the past, the ways to amblyopia neural mechanism research are given priority to visual electrophysiology and so on, which express the result use two -dimensional form, these ways mainly research the functions of the state before the lateral geniculate body. For the study of optic center, animal models are used to research it. But these kinds of methods are unable to accurately detect amblyopia neural mechanisms of human beings. Vulnerable to a variety of factors, it is difficult to finish the amblyopia treatment effect evaluation. Functional magnetic resonance imaging ( fMRI ) can reflect the three-dimensional visual cortex neuron activity noninvasively and accurately, and give rise to amblyopia neural mechanism and therapeutic effect evaluation. Therefore, in this paper, the amblyopia neural mechanisms and visual center after treatment effect evaluation of fMRI research progress are summarized.

Objective To construct the plasmid that can produce long,double-stranded RNA and identify nonspecific apoptosis induced by long, double-stranded RNA in human osteosarcoma cells. Methods Plasmid pCI-neo-dsRNA was constructed by two promoters driven DNA sequence based on nontoxic, completely exoteric gene EGFP from the head and the end simultaneously to synthesize sense and antisense RNAs. Human osteosarcoma cells MG63 were transfected with pCI-neo-dsRNA and 48 h later the transfected cells were assessed by Apoptosis Detection System, FCMand MTT method. Results Plasmid pCI-neo-dsRNA was constructed successfully, MTT measurement showed that the absorbance of cells decreased gradually with the increase of plasmid pCI-neo-dsRNA dose(0.05 ?g, 0.10 ?g, 0.15 ?g, 0.20 ?g,0.25 ?g,0.30 ?g). MG3 transfected with pCI-neo-dsEGFP presented a great amount of irregular green fluorescence that indicated cell apoptosis. As the quantity of dsRNA increased, the percent of apoptosis cells also raised. While the dose of pCI-neo-dsEGF was 3.0 ?g, the apoptotic results of pCI-neo-dsEGF in MG3 were similar to that of 5-FU. Conclusion Long, double- stranded RNA could trigger human osteosarcoma cell apoptosis and the further research on using long, double-stranded RNA in osteosarcoma gene therapy can be done based on this theory.
