Silk damping is well known in the study of cosmic microwave background（CMB） and accounts for suppression of the angular power spectrum of CMB on large angular multipoles. In this article, we study the effect of Silk damping on the scalar-induced gravitational waves（SIGWs）. Resulting from the dissipation of cosmic fluid, the Silk damping notably suppresses the energydensity spectrum of SIGWs on scales comparable to a diffusion scale at the decoupling time of weakly-interacting particles. The effect offers a novel observable for probing the underlying particle interaction, especially for those mediated by heavy gauge bosons beyond the standard model of particles. We anticipate that pulsar timing arrays are sensitive to gauge bosons with mass ～10～3-10～4 GeV, while space-and ground-based interferometers to those with mass ～10～7-1012GeV, leading to essential complements to on-going and future experiments of high-energy physics.

目的探讨脾多肽注射液对乳腺癌荷瘤小鼠抗肿瘤治疗的效果和安全性以及对乳腺癌肿瘤微环境中淋巴细胞亚群比例的影响。方法动物实验使用20只BALB/C小鼠进行皮下瘤造模。造模成功小鼠随机分为3组:对照组、脾多肽低剂量组和脾多肽高剂量组。脾多肽低剂量组和脾多肽高剂量组连续10天分别每天尾静脉注射1 mg/kg和10 mg/kg的脾多肽注射液,对照组小鼠经尾静脉注射等体积生理盐水。实验过程中记录小鼠体质量和肿瘤体积变化,实验结束后测量小鼠肿瘤组织的体积和质量并使用流式细胞术分析小鼠肿瘤组织单细胞悬液中不同类型淋巴细胞的比例。体外实验则建立人外周血单核细胞(PBMCs)和乳腺癌MDA-MB-231细胞共培养模型,实验组培养基中分别加入0.8μg/ml(脾多肽低剂量组)、8μg/ml(脾多肽高剂量组)的脾多肽注射液,对照组加入等量的完全培养基。处理48 h后收集共培养体系中的PBMCs,用流式细胞术分析PBMCs中淋巴细胞亚群比例变化。结果各组荷瘤小鼠的体质量和肿瘤体积均随着时间的推移增长。与对照组相比,不同剂量脾多肽治疗组的荷瘤小鼠在使用脾多肽治疗10天后,小鼠体质量变化率、肿瘤体积和肿瘤质量的差异无统计学意义(P>0.05)。与对照组相比,脾多肽治疗组能够上调乳腺癌荷瘤小鼠肿瘤组织中CD4^(+)T淋巴细胞和CD8^(+)T淋巴细胞的比例(P<0.05)。此外,对于MDA-MB-231细胞与PBMCs的共培养体系,低剂量和高剂量脾多肽均能够不同程度地上调PBMCs亚群中CD4^(+)T淋巴细胞和CD8^(+)T淋巴细胞的比例(P<0.05)。结论脾多肽能增强乳腺癌荷瘤小鼠的抗肿瘤免疫能力且对于小鼠无明显毒副作用并增加乳腺癌肿瘤免疫微环境中CD4^(+)T淋巴细胞和CD8^(+)T淋巴细胞的比例,具有进一步应用于临床研究中的价值。
