Abstract］ objective to discuss radiological findings of parosteal osteosarcoma on emphasis combined with clinical pathology and literature.methods 4 cases of parosteal osteosarcoma proved by operation and pathology were analyzed retrospectively.results female was 3 cases,male was 1 case,average age was 30.5 years old,these tumors were arised on posterior border of distal femur and popliteal cavity,presented as lobular dense ossified mass,defined lesion.one case had villose margin.a thin narrow lucent zone separated the mass from the cortex at two cases.one case underwent angiography,there was no malignant feature.conclusion parosteal osteosarcoma may be divided into low-grade type and high-grade type.radiological manifestations of early stage possess character,early diagnosis conduces to establish rational treating plan and evaluate prognosis.

目的 结合临床病理学特征和文献资料，重点讨论皮质旁骨肉瘤的x线特征。方法收集经手术、病理证实的皮质旁骨肉瘤病例4例，对其进行回顾性分析。结果 4例患者女3例，男1例，平均年龄30.5岁，肿瘤均发生于股骨远端后侧和腘窝处，表现为分叶状致密骨化肿块，边界清晰，其中1例边缘呈绒毛状改变，2例有细窄透亮带与骨皮质相隔，1例行血管造影，未见血管池等恶性征象。结论皮质旁骨肉瘤分为低度恶性和高度恶性两种，早期影像学表现有特征性，早期诊断有助于制订相应的治疗方案和评估预后。

Three categories of cytokines, including Thl/Th2 cytokines, chemokines and adipocytokines, are involved in the physiopathological process of NASH. In order to elucidate the significances of cytokines in the pathogenesis, serological diagnosis, and treatment efficacy evaluation of HASH, we reviewed the documents on the relationship between cytokines and non-alcoholic steatohepatitis.
