In order to analyze experimentally the back-scattering micro-spectrum difference between human normal stomach epithetic cell and the cancerous cell to provide optical technique for clinical checking,a micro-spectral measurement setup for checking cell was established based on fiber confocal microscopically imaging technique combined with cell light scattering theory. It could provide micro-imaging and micro-medical spectral information simultaneously.

The data shoewed that esculetin, resveratrol enhanced LPL expression up to about 1.2 ~3.5 fold compared with the control group. In addition to fibrates, however, no effect on LPL expression by curcumin was observed. We concluded that esculetin and resveratrol enhanced LPL expression on CHO-K1 cell. We hope that we can apply these drugs to mutant form LPL, furthermore apply theses drugs into clinical treatment.

利用药物处理有转染带有完整人类脂蛋白解脂酶启动子和脂蛋白解脂酶cDNA 序列(-1715 ~+1643)质体的CHO-K1细胞，从细胞培养液以及细胞溶解物中发现，除了curcumin之外所有药物都可以使得细胞培养液以及细胞溶解液内的脂蛋白解脂酶活性有1.2至3.5倍的上升，由此结果可知除了curcumin外，esculetin和白藜芦醇以及其他fibrate药物可降低三酸甘油脂血症。

Mucous membrane protective screen is formed by the join between cell of alvine mucous membrane and cell, atrophy of cell of alvine mucous membrane, wither dies, cellular connective can send alvine path to connect flabbily appear a gender to increase, provide passageway; chemical protective screen for the bacterium inside bowel and toxin the digestive juice that shows epithelial excretive mucus and alvine memory are in bowel and digest enzymatic the chemistry that waits for material to reach its to develop.

METHODS: A model of T cell activation and proliferation was established by stimulated the cells with Con A.T cells were treated with different concentrations of CPT. The expression of CD69, the early marker of CD3(superscript +) T cell activation, was measured by FACS. The proliferation index was determined by carboxyl fluorescin diacetate succinmidyl ester by flow cytometry. The cell-cycle distribution was analyzed by propidium iodide staining.
