objective effects of plant tannins,chebulinic acid and tellimagrandin i on chemically induced hemoglobin synthesis in k562 cells were investigated.methods the hemoglobin synthesis situation was assayed with benzidine staining.erythroid antigens glycophorin a expression on the surface of k562 cells was labeled by direct immunofluorescence using fluorescein isothiocyanate-conjugated anti-gpa antibodies.then flow cytometric analysis was performed to detect gpa expression levels on surface of the cells.results both chebulinic acid and tellimagrandin i could inhibit the hemoglobin synthesis of butyric acid and hemin-treated k562 cells in a concentration-dependant manner.however,the ba-induced k562 cells were more sensitive to two tannins than heroin-induced cells.conclusion chebulinic acid and tellimagrandin i have inhibitory effect on the erythroid differentiation.

目的 研究可水解单宁诃子酸和特里马素i对氯化高铁血红素和丁酸钠诱导k562细胞红系分化的影响。方法四甲基偶氮噻唑蓝法分析诃子酸和特里马素i对k562细胞生长的影响，联苯胺染色法检测血红蛋白合成情况，应用免疫荧光和流式细胞术检测血型糖蛋白a在细胞表面的表达。结果诃子酸和特里马素i在0.04～0.09？mmol／l浓度下均可显著抑制k562细胞的生长增殖。2种单宁化合物(0.002～0.01？mmol／l)可显著抑制丁酸钠诱导的k562细胞血红蛋白合成，2种单宁化合物(0.01～0.05？mmol／l)还可显著抑制氯化高铁血红素诱导的血红蛋白合成，特里马素i(0.01？mmol／l)还抑制丁酸钠诱导的gpa在细胞表面表达。结论诃子酸和特里马素i对红系分化有抑制作用。

Methods: CD34(superscript +) cells from fetal liver were isolated with a magnetic cell sorting kit and were cultured. Cells pretreated with or without protein kinase C inhibitor chelerythrine chloride (3 μmol/L) were induced by 5 ×10^(-7)mol/L tretinoin for 24 h, and then incubated in serum-free medium. Expressions of genes in treated cells were assayed by Western blotting and RT-PCR.

L-FABP gene may be involved in the carcinogenesis of human HCC. Expression of L-FABP is associated with VEGF expression, suggesting that L-FABP promotes the growth of blood vessels by taking up the fatly acids from the bloodstream, and both of them produce a marked effect on energy metabolism in HCC.

L-FABP、VEGF基因以及蛋白质在肝癌组织中表达均显著上调，并且二者具有正相关性、我们推测L-FABP在获取更多的脂肪酸的同时可以促进血管的增生，进而促进了肝癌的发展。
