文摘Sections of 30 cases of human cirrhosis were stained with rabbit anti-insulin-likegrowth factor Ⅱ(IGF Ⅱ)by double PAP method.By the serological examination 15 patientsshowed HBV infection and sections of 14 eases were HBsAg postively with a total rate of 67％(20 cases).The IGF Ⅱ was positive in the cytoplasm of all the liver and ductular cells.Binucle-ated,polypoid liver cells and the peripheral cells of the lobules or nodules were distinctly posi-tive,The liver cells which were strongly positive were a kind of thin polygonal cells with asmall oval or a round deeply stained nucleus in each.They might exist sporadically in the lob-ules or in the marginal portion of a nodule.These liver cells are quite different from the so-called oval cells which are derived from the proliferating ductules and are generally believed tobe responsible for the pathogensis of hepatoma.
文摘目的探讨急性脑梗死(acute cerebral infarction,ACI)患者脑电图、血清胰岛素生长因子1(insulin-like growth factor 1,IGF-1)、神经元特异性烯醇化酶(neuron-specific enolase,NSE)与病灶体积及美国国立卫生研究院卒中量表(National Institute of Health stroke scale,NIHSS)评分的关系。方法选择2021年8月至2022年12月在南京市溧水区人民医院神经内科首次确诊的ACI患者218例,根据病灶体积分为大体积组63例、中体积组103例和小体积组52例。检测患者脑电图(δ+θ)与(α+β)功率比[(δ+θ)/(α+β)ratio,DTABR]、大脑对称指数(brainspine interface,BSI)、血清IGF-1和NSE水平,观察上述指标与MRI检查脑梗死病灶体积、NIHSS评分、阿替普酶溶栓后2周、4周时NIHSS评分的相关性。结果中体积组和大体积组IGF-1水平明显低于小体积组,NSE、DTABR、BSI明显高于小体积组(P<0.05);大体积组IGF-1水平明显低于中体积组,NSE、DTABR、BSI明显高于中体积组(P<0.05)。DTABR、BSI、血清NSE与病灶体积(r=0.563,P=0.000;r=0.318,P=0.038;r=0.673,P=0.000)和治疗前NIHSS评分(r=0.499,P=0.000;r=0.362,P=0.013;r=0.750,P=0.001)呈显著正相关。血清IGF-1水平与病灶体积(r=-0.572,P=0.000)和治疗前NIHSS评分(r=-0.438,P=0.001)呈显著负相关。DTABR、BSI、血清NSE、病灶体积均与溶栓后2、4周NIHSS评分呈正相关,IGF-1与溶栓后2、4周NIHSS评分呈负相关(P<0.05,P<0.01)。结论ACI患者脑电图、IGF-1和NSE与病灶体积和溶栓后NIHSS评分显著相关。
