乳腺癌是全球发病率最高的恶性肿瘤之一。近年来肿瘤的各类研究均取得了诸多进展。随着对肿瘤认识的不断深入,肿瘤细胞生长的微环境对癌症发生发展的影响受到越来越多的关注。肿瘤相关成纤维细胞(CAFs)作为肿瘤微环境的重要成分,受肿瘤调控的同时还可通过多种途径释放细胞因子、外泌体等参与调节免疫微环境、重塑细胞外基质,以及促进肿瘤发生、迁移、侵袭和耐药等过程。本文对CAFs在乳腺癌中作用的最新研究进展进行综述,阐述免疫微环境中CAFs与乳腺癌细胞的相互作用模式,以及CAFs促进乳腺癌细胞增殖、侵袭、转移、耐药等恶性生物学行为的多种途径,探讨以CAFs为靶点进行乳腺肿瘤早期筛查及治疗的潜在效能。

Frequency tunability has become a subject of concern in the field of high-power microwave（HPM） source ***, little information about the corresponding mode converter is available. A tunable circularly-polarized turnstilejunction mode converter（TCTMC） for high-power microwave applications is presented in this paper. The input coaxial TEM mode is transformed into TE（10） mode with different phase delays in four rectangular waveguides and then converted into a circularly-polarized TE（11） circular waveguide mode. Besides, the rods are added to reduce or even eliminate the reflection. The innovations in this study are as follows. The tunning mechanism is added to the mode converter, which can change the effective length of rectangular waveguide and the distance between the rods installed upstream and the closest edge of the rectangular waveguide, thus improving the conversion efficiency and bandwidth. The conversion efficiency of TCTMC can reach above 98% over the frequency range of 1.42 GHz–2.29 GHz, and the frequency tunning bandwidth is about 47%. Significantly, TCTMC can obtain continuous high conversion efficiency of different frequency points with the change of tuning mechanism.
