While erthrocyte, hemoglobin and Hela cell were under oxidative damage induced by the hydrogen peroxide (H2O2) or tert-butyl hydroperoxide on different concentrations of dihydromyricetin, hemolysis rate of erythrocyte and methemoglobin converted from hemoglobin was estimated by ultraviolet-visible absorption spectroscopy. Whereas mmalondialdehyde from erythrocyte was measured by thiobarbituric acid colorimetry, the cellular viability of Hela cell was examined using MTT 3-(4, 5-dimethylthiazol-2-yl-2, 5-diphenyl tetrazolium bromide assay.

在不同的二氢杨梅素浓度下，用过氧化氢或过氧化特丁烷对红细胞、血红蛋白和Hela细胞进行氧化伤害，以紫外－可见光分光光度法检测红细胞溶血率和由正常血红蛋白生成的高铁血红蛋白，硫代巴比妥酸法测定红细胞中的丙二醛，MTT法检测Hela细胞的活力。

Leptin is a hormone that regulates metabolic efficiency,energy expenditure.It is mainly produced in adipose.Now we acknowlege that leptin is also present in placenta.It can mediate the excretory function of cytotrophoblast and vascular growth. Leptin participates in pregnancy complication.

瘦素是由肥胖基因编码的调节能量代谢的物质，主要由脂肪细胞合成，现已证实胎盘也合成瘦素，可调节滋养细胞的分泌功能及胎盘血管的生成，与生殖及PIH等疾病密切相关。

BACKGROUND: Bone morphogenic protein 2 is one of the most important growth factors in the healing of bone fracture. The main function is to promote the undifferentiated mesenchymal cells and bone cells to recruitment and differentiate. It is the promoter of bone formation. The BMP-2 gene is an ideal gene that can be used to repair the bone.

背景：骨形成蛋白2是骨基质中最重要骨生长因子，主要生物学作用是促进未分化的间充质细胞和骨系细胞的募集和分化，是骨生成的启动因子，可以作为骨修复基因治疗的理想目的基因。

Methods: CFU-MK and the model of thrombopenia of aplastic anemia were analysed by methylcellulose culture or with sera from patients with aplastic anemia. The number of megakaryocyte colony-forming unit and the content of CD41+ cells in CFU-MK were measured simultaneously. Results: After 14 days of culture, the number of CFU-MK and megakaryocyte cluster-forming unit of the model groups were significantly less than that of the normal control groups.

EphA2 as a part of RTKs superfamily is lower expressed in various kinds epitheliums usually.It was found higher expressed in many tumor tissues recently.It takes part in the regulation of the grew、exist、migrate and invasion of tumor cells,it is also involved in the formation of the tumor vessel and vasculogenic mimicry.

EphA2作为受体酪氨酸激酶(receptor tyrosine kinases，RTKs)家族成员之一，通常以相对较低的水平表达在成人各种上皮细胞中，近来研究发现其在许多肿瘤中高表达，参与调节肿瘤细胞的生长、生存、迁移和侵袭，还涉及肿瘤血管和血管生成拟态的形成。

The detection of the biological activity of the product was performed with MTT and CAM assay.
