Gene chip study on cerebral gene of effect of Jinkui Shenqiwan and Youguiwan on mouse model of kidney-yang asthenia with syndrome disproved according to therapeutic efficacy of drugs used / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To inquire into the cerebral gene change of effect of Jingui Shenqiwan and Youguiwan for animal model of kidney-yang asthenia caused by excessive physical and sexual activities, which may study the effect mechanism of the medicine with syndrome disproved therapeutic efficacy of drugs used.</p><p><b>METHOD</b>Male mice of Kunming species, weight 35-40 g, and female weight 28-35 g were randomly divided into four groups control group, model group and treatment groups of Jigui Shenqiwan and Youguiwan in which there were ten male mice, fifteen ones, ten ones and ten ones, respectively. All of them were fed normally, and poured into their stomach with 0.5 mL of distill water for each mouse in the control group and model group, and with 0.5 mL suspension of the drugs (including 1.1 g x kg(-1) drug) for each one in the treatment groups every day. The mice in the model group and treatment groups were kept by means of each male mouse with six female mice in the same cage, and all male mice swam until they gradully submerged and were scooped up from water once everyday for lasting four weeks to induce the kidney-yang asthenia with excessive physical and sexual activities. Animals' manifestation such as fearing cold, activity and responses, mouse' fur and so on were observed. The brain gene were detected with the mouse brain gene chip of 36K Mouse genome array made by Capital Bio Corp. Beijing, China, and the differential expression gene were screened according to the ratio equal to or above 2 and equal to or below 0.5 with the related fluorescent intensity comparing the two groups, which could be further verified in the light of partly differential expression gene with qRT-PCR.</p><p><b>RESULT</b>The mouse model of kidney-yang asthenia in the model group was successfully induced by way of excessive physical and sexual activities. There were twenty-three genes among up-regulated genes in the model group versus control group but down-regulated genes in the treatment groups versus model group, chiefly including the genes association with inflammation/immunization, neurotransmissions/ signal transduction and so on. There were six genes among the down-regulated genes in the model group versus control group but upregulated in the treatment groups versus model group, mainly involving the related genes of cellular cycle and structure, neurotransmissions/signal transduction, transcription and et al.</p><p><b>CONCLUSION</b>Jigui Shenqiwan and Youguiwan may make it markedly up-regulated to notably down-regulated genes of hormone and melanin-concentrating hormone (MCH) for model of mouse of kidney-yang asthenia, and promote cellular proliferation, which can inquire into effect mechanism of the drug in genetic level at the same time.</p>
