报道作者研制的体外震波碎石机的结构、性能和临床应用初步情况。该台碎石机属电极放电类型，但免除了水槽，电极寿命长，病人不用麻醉。临床首批治疗30例上尿路结石，结石均被粉碎，病员无痛苦不适，局部皮肤无灼伤、瘀血点，未见心电图异常改变，治疗后半小时至24小时开始排石。短期随访，12例于3天～30天内排尽结石，15例在继续排石中，3例肾盏结石排石量较少。取得了较满意的疗效。

Compared with control group,the ADM level in the left lung increased(P＜0.001),but the ADM levels in the heart,liver,kidney decreased.The ratio of wet to dry weight of the left lung in experiment group was 6.491±0.248,and 5.937±0.361 in control group,there was no significant difference（P＞0.05）.No alveolar wall thicken,alveolar and mesenchyma edema were found in two groups.

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。
