M2 macrophage-related molecular subtypes and prognostic index for prostate cancer patients through integrating single-cell and bulk RNA sequencing analysis

引用

Genes & Diseases 2024年第4期11卷 131-133页

作者： Dechao Feng Xu Shi Dengxiong Li Ruicheng Wu Jie Wang Wuran Wei ping han Department of Urology Institute of UrologyWest China HospitalSichuan UniversityChengduSichuan 610041China

Prostate cancer(PCa)is considered as an age-related disease and accounts for the most prevalence of urinary malignancies in men.1 We previously analyzed the cellular landscape of tumor microenvironment in PCa patients,where we found that cancer-related fibroblasts might play an important role in tumorigenesis and the development of PCa and tumor-associated macrophage(TAM)could function synergistically with them.2 Thus,we further integrated single-cell and bulk RNA sequencing with meta-analysis to specify the prognostic effect of TAM on PCa and construct molecular subgroups and predictive index to guide clinical practice.

商标蟑螂作为知识产权领域“蟑螂家族”的一员,广泛出现在以商标注册制为基础的国家,恶意取得商标后并不实际使用商标,而是专门通过向他人发起商标侵权诉讼或者以发起商标侵权诉讼相要挟以获取高额利润。商标蟑螂骚扰实体企业经营,扰乱商标注册秩序,严重破坏我国市场营商环境。究其原因,制度缺陷和公众认知不足是商标蟑螂现象在我国愈演愈烈的两大根源。对此,应强化商标使用在商标取得、维持和保护阶段的重要性,提高对真实使用的商标的司法保护水平,以缩小商标实际权利和纸面权利之间的权利保护缺口。同时,加强国内国际商标信息共享,提升公众的知识产权文化意识,从而有效治理商标蟑螂现象。

兰州大学的创始时间可以溯源至其前身甘肃官立法政学堂创建的1909年,但是对学校图书馆的始建时间,长期以来没有确切而符合历史事实的认定,形成了多种歧异之说。首先兰州大学图书馆内部对建馆时间见解不一,20世纪先后有甘肃公立法政专门学校建馆、1946年建馆和1927年建馆等不同说法;进入21世纪,更是将建馆时间向建校时间看齐,形成了普遍认可的1909年建馆说。其次既有两版兰州大学校史均有疑似1928年建馆和甘肃学院建馆的两歧说法。学界对兰州大学图书馆建馆时间的表述,大都是直接或间接沿袭本校的说法。通过考察和分析校史档案,并参稽其他相关历史文献,认为图书馆的始建时间应在1926年至1929年2月之间,当时正值甘肃公立法政专门学校晚期至兰州中山大学初期阶段,学校至迟在1927年已拥有图书馆馆舍实体,但尚未正式建馆,正式建馆时间应为兰州中山大学初创之际的1928年4月。
