青稞的日常,西藏有一句传统谚语叫“主意心里藏,粑袋中装”,寓意一个人心中有把握、有信心,类似“胸有成竹”。曾经在雪域先民遥远的朝圣旅途或放牧日常,装在褶皱的羊羔皮口袋里的粑是人们能够和环境不确定性抗衡的重要口粮。只要有一口袋粑,再陌生未知的长途旅程,都能骑上马随时启程。粑,是我们的信心。藏族长辈都坚信,正是因为吃粑和耗牛肉,我们的祖辈才能够在这片缺氧寒冷的高地上繁衍生息。

Rapid solidification of Cu-Pb monotectic alloys has been accomplished during free fall in a 3 m drop tube. Both macrosegregated and uniformly dispersed structures are observed in Cu-40 wt pct Pb alloy droplets, whereas droplets of composition Cu-64 wt pct Pb exhibit only macrosegregation morphologies. The microstructures are strongly dependent on droplet size. The higher undercooling tends to facilitate liquid phase separation and results in more extensive macrosegregation in smaller droplets. There exists a pronounced tendency for the Pb-rich liquid to occupy the surface of the droplets of both compositions, resulting from the quite lower surface tension of the Pb-rich phase and causing a Pb-rich layer at the surface of the solidified droplet. The nucleation of monotectic cells in the Cu-40 wt pct Pb droplets with dispersed structures preferentially occurs at the droplet surface. A single nucleation event takes place more frequently as droplet size is reduced.

INCREASING evidence has demonstrated that the locally controlled proteolytic activity generatedby coordinated expression of tPA and PAI-1 in different tissues may play an important role inmany reproductive events. These are largely related to fibrinolytic activity. They include folli-cle rupture, luteolysis, spermatogenesis and trophoblast implantation. Parturition, whichis a complex process, may also be associated with tissue destruction. Detachment of placentaldecidua and partial breakdown of fetal membranes are possible examples. It has been

cd30可在多种淋巴瘤中表达,其中经典型霍奇金淋巴瘤(classical Hodgkin lymphoma,CHL)和间变性大细胞淋巴瘤(anaplastic large cell lymphoma,ALCL)最为常见。近年来,靶向cd30的抗体药物偶联物维布妥昔单抗已获批应用于复发/难治性CHL和ALCL患者的治疗,并取得显著疗效。然而,该靶向治疗药物能否使其他类型淋巴瘤患者获益目前尚不明确,精确评估cd30表达水平对此类淋巴瘤患者的临床试验和个体化治疗有重要的指导意义。目前,cd30检测仍主要通过免疫组织化学染色的方法,尚缺乏统一、规范的检测流程及结果判读标准。本文通过分析cd30的检测现状,联合多中心研究探索cd30免疫组织化学检测流程及结果判读方法,并结合文献和专家经验,最终达成淋巴瘤cd30免疫组织化学检测及结果判读共识,希望能有助于淋巴瘤cd30表达的规范化检测。

cd30是肿瘤坏死因子受体超家族成员,在经典型霍奇金淋巴瘤(classical Hodgkin lymphoma,CHL)、间变性大细胞淋巴瘤(anaplastic large cell lymphoma,ALCL)等多种淋巴瘤中均有不同程度的表达。除了作为诊断和评价预后的标志物,cd30还是抗体药物偶联物的有效靶点。随着以cd30为治疗靶点的多项临床试验相继开展,淋巴瘤cd30表达水平的规范化检测日益重要。本文综述了cd30在不同类型淋巴瘤中的表达特征以及cd30在检测和判读方面所面临的挑战及可能的解决方案。
