　　背景肝細胞受損可增加糖尿�。―iabetes mellituspatients,DM）患者發(fā)病率和死亡率。已公認,高血糖是DM患者肝損害發(fā)病的主要原因,與DM相關(guān)的肝細胞損害是DM患者常見的并發(fā)癥。磷酸肌酸（Phosphocreatine,PCr）分子作為一種可迅速動員、回收ATP,對腦和骨骼肌的能量儲備,可作為細胞能量儲備形式,它具有多種活性。然而,PCr是否具有保護DM相關(guān)肝損傷的作用尚未見報道。本研究旨在評價PCr是否能保護DM并發(fā)的肝損傷,并探討其在體內(nèi)外作用機制。材料與方法體外研究:丙酮醛（methylglyoxal,MGO）,是葡萄糖的活性代謝產(chǎn)物,與高血糖可引起DM相關(guān)的肝細胞損傷,且與肝細胞損害進展關(guān)系密切。Hep G2細胞培養(yǎng)及細胞進行預(yù)處理MGO兩小時,然后,分別用不同濃度的PCR處理細胞（5m M,10m M,20m M）。采用MTT法研究胞形態(tài)學(xué)、細胞毒性、細胞凋亡;流式細胞儀Annexin V-FITC、Calcien法分別檢測細胞凋亡、增殖試驗。通過Western blotting檢測凋亡蛋白Bax、Bcl-2和Caspase-3、Caspase-9蛋白表達...
