Zhongguo shiyan zhenduanxue肝细胞癌是全球范围内发病率和死亡率较高的恶性肿瘤。热消融术因其微创、高效的特点被广泛应用于肝细胞癌的治疗。然而，热消融术后的高复发率严重影响患者的长期生存率。超声造影不仅能够实时评估消融效果，还可通过分析增强模式监测复发风险。与 CT/MRI 对比，CEUS 时间分辨率高、灵敏度优。同时，CEUS 提示肝癌热消融后复发有诸多征象，如动脉期强化特征、消融边缘、微血管侵犯等与复发相关。此外，多模态超声造影、融合成像以及三维超声造影等新技术的出现，进一步提升了影像诊断的精准性与治疗指导能力 ...

供者淋巴细胞回输对异基因造血干细胞移植后急性白血病复发的影响
Zhongguo shiyan zhenduanxue, 2012 异基因造血干细胞移植（Allo-HSCT）是治疗急性白血病的有效手段,但移植后复发是影响治疗成功的主要因素。根据国际外周血和骨髓移植登记研究中心的资料,1998—2002年间所进行自体移植患者死亡原因中复发占75%,而HLA相同同胞供体（MSD）移植和非血缘关系供体（MUD）移植后死亡原因中复发分别为38%和32%[1 ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Infrared (IR) stealth is crucial for improving the survivability of equipment. The growing demand for service in marine environments poses new challenges to the composition and structural design of existing IR stealth coatings. This study first investigates the effects of NaCl/water vapor corrosion on the IR stealth performance of GH3536 and a

Zhongshan Daxue xuebao. Yixue kexue ban, 2014 【目的】 探讨增殖相关抗原Ｋｉ－６７在木村病（ＫＤ）患者中的表达及其与复发相关因素的关系。 【方法】 用链酶素生物素－过氧化物酶（ＳＰ法）对４０例经手术治疗病理证实为木村病的石蜡组织检测Ｋｉ－６７的表达，评估其在复发和无复发患者中的表达情况。【结果】在４０例患者中，男性３７例，女性３例，年龄１０ ～ ７５岁，３４例患者的主要肿块位于头颈部，其余７例主要肿块位于上腭或腹股沟区域，肿块最大直径为６．５ ｃｍ。Ｋｉ－６７在木村病复发患者（１１／４０）淋巴结组织中（不包括生发中心）表达高于无复发的患者（Ｐ＜ ０．

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The low energy density of sodium‐ion batteries (SIBs) remains a major barrier to their large‐scale deployment. Alloy‐based anodes represent a promising class of materials owing to their high specific capacity and low operating potential for sodium storage. However, their practical application is hindered by severe volume expansion upon cycling.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Many metallic components are frequently subjected to coupled environments of friction and vibration, stemming from interfacial contact and relative motion between mating parts or external stimuli. Consequently, it is imperative for these components to exhibit a synergy of high wear resistance and superior damping properties.
