乳腺炎性肌纤维母细胞瘤的研究进展

炎性肌纤维母细胞瘤（inflammatory myofibroblastic tumor，IMT）作为一种低度恶性潜能的间叶组织来源的肿瘤，病因及发病机制不明。主要见于儿童和青少年,最常见的部位是肺、肠系膜、网膜，发生于乳腺的比较罕见，且往往单发。乳腺炎性肌纤维母细胞瘤的临床症状及影像学特点均不典型，术前易造成误诊，本文复习国内外文献报道的乳腺炎性肌纤维母细胞瘤，从发病机制、临床表现、影像学特征、病理学特征、鉴别诊断、治疗及预后等方面作一系统综述。     

Secretion,blood levels and cutaneous expression of TL1A in psoriasis patients

TL1A is a TNF‐like cytokine which has been shown to co‐stimulate TH1 and TH17 responses during chronic inflammation. The expression of this novel cytokine has been investigated in inflammatory disorders like rheumatoid arthritis and inflammatory bowel disease, but little is known about expression and induction in psoriasis. Indeed, the pathogenesis in psoriasis is still not fully understood and it is speculated that cytokines other than TNF‐α are important in subsets of patients. Also, for patients with severe disease that are treated with systemic anti‐TNF‐α blockade, novel candidates to be used as disease and response biomarkers are of high interest. Here, we demonstrate TL1A expression in biopsies from psoriatic lesions. Also, we investigated spontaneous and induced TL1A secretion from PBMCs and blood levels from a cohort of psoriasis patients. Here, increased spontaneous secretion from PBMCs was observed as compared to healthy controls and a small subset of patients had highly elevated TL1A in the blood. Interestingly, activation of PBMCs with various cytokines showed a decreased sensitivity for TL1A activation in psoriasis patients compared to healthy controls.TL1A levels in blood and biopsies could not be correlated with disease activity with this patient cohort. Thus, additional large‐scale studies are warranted to investigate TL1A as a biomarker.     

放疗在肝癌治疗中应用的研究进展

肝癌是临床上常见的恶性肿瘤，因早期症状不典型，至发现时往往已为中晚期，失去最佳手术治疗时机和机会。作为非手术治疗之一的放射治疗技术，其发展在近年来已有了较大的进步。放疗包括体外放疗和体内放疗，皆具有一定的治疗效果和相对可控的不良反应。本文就肝癌放射治疗的应用进展作一综述。
