国家癌症中心发布的最新统计数据显示,肺癌仍是我国发病率和死亡率最高的恶性肿瘤。同时,肺癌的发病率及死亡率逐年攀升,对癌症患者及社会造成了严重的负担。非小细胞肺癌(non-small cell lung cancer,NSCLC)是肺癌的主要病理类型,约占全部肺癌的85%左右。晚期NSCLC患者的5年生存率较低,目前,化疗仍然是晚期肺癌治疗的基石。细胞毒类药物会损伤骨髓内的造血干细胞,导致骨髓抑制,使患者因不能耐受而中止治疗。针对骨髓抑制的传统治疗手段可能会引发其他不良反应,如骨髓造血储备功能耗竭等。2022年7月,曲拉西利获批用于预防小细胞肺癌化疗引起的骨髓抑制。曲拉西利能有效预防化疗引起的骨髓抑制,并且不会拮抗化疗的抗肿瘤作用。本文特报道1例曲拉西利联合免疫联合化疗一线治疗晚期NSCLC的病例,以期为临床实践提供进一步的参考。

为了研发一种新型复合生物油再生剂,并探究其对长期老化沥青化学成分的再生作用,采用蓖麻油植物沥青(COA)与环氧大豆油(ESO)按照不同复配比例制备了复合生物油再生剂,确定了复合生物油中蓖麻油植物沥青与环氧大豆油的最优复配比例;基于红外光谱变化研究了蓖麻油植物沥青与环氧大豆油的原位动态化学反应机制,以及沥青再生前后的化学成分变化情况。结果表明,按照蓖麻油植物沥青和环氧大豆油质量比1∶3复配制得的复合生物油再生剂可以有效地将长期老化沥青的基本性能恢复至老化前水平。蓖麻油植物沥青和环氧大豆油发生了开环缩合反应,生成含脂肪族的聚合物,该反应在老化沥青再生过程中仍然可以持续地进行,并继续影响再生沥青的基本性能。在蓖麻油植物沥青和环氧大豆油的共同作用下,再生沥青中的亚砜基和羰基官能团含量减少。该研究提供了一种长期老化沥青的复合生物油再生剂,并揭示了其对长期老化沥青化学成分的影响及再生作用。
