Abstract］ objective to improve the diagnosis of non-ossifying fiboma by analysing its x-ray feature.methods plain x-ray films was performed in all patients.x-ray finding in 8 cases with pathologically-confirmed non-ossifying were analyzed.results the clinical symptom was mild,the lesions occurred usually at the metaphysis of the long bones,the affected bones included femur（n=4）,tibia（n=3）,humerus（n=1）.cortical type was seen in 5 cases,presenting as unilocular or multilacular transparent areas with in the cortex or tightly beneath the cortex,the lesion had a sclerotic margin.which was more obvious at the marrow side.medullary type was seen in 2 cases.the lesion was located at the center of the bone and grew centrally.the tumor was manifested as unilocular or multilocular.tramsparent area with sclerotic border and the bone cortex became thinner with slightly expanding on 11 sides.conclusion plain radiography is the elementally means to detect this disease.based on the typical x-ray signs of non-ossifying fibroma combined with clinical data,correct preoperative diagnosis can be made in most cases.

目的 探讨非骨化性纤维瘤的x线表现以提高诊断水平。方法所有病例均摄有x线平片，分析经病理证实的8例非骨化性纤维瘤。结果临床症状轻，好发于下肢长骨干骺端或骨干，股骨4例，胫骨3例，肱骨1例。皮质型5例，表现为皮质内或紧贴皮质下的单层或多层透亮区，病变向骨内发展进入髓腔，周围有致密硬化带环绕，以髓腔侧明显；髓质型2例，病灶在骨内中央发展，显示为单房或多房透亮区，边缘有硬化，骨皮质菲薄，轻微向周围膨隆。结论 x线为最基本的检查方法，典型病例x线平片结合临床症状即可明确诊断。

The experimental group has various changes in the different density of potentill anserine extract.

实验组不同浓度的蕨麻提取物对小鼠肺组织的影响不同，Ⅰ组小鼠肺组织表面肉眼见不同程度的散在点状出血、显微镜下肺泡腔内见散在红细胞；Ⅱ组小鼠肺组织表面肉眼无明显异常，显微镜下肺泡腔内见散在红细胞及淡伊红色液体，两组均见肺泡壁毛细血管扩张充血及毛细血管内皮细胞呈不同程度的增生肥大。

The experimental group has various changes in the different density of potentill anserine extract. The small rat pulmonary tissue surface ofⅠgroup can see sporadic petechia of different degree; pulmonary alveolus cavity can see sporadic erythrocyte under the microscope. The small rat pulmonary tissue surface of Ⅱ group is no obvious abnormality by naked eye; pulmonary alveolus cavity can see sporadic erythrocyte and thin powder color liquid under the microscope. Two groups all have the capillary vessel of alveolar wall dilation and the endothelial cell hyperplasia and hypertrophy in different degree.

BCPA can provide increased pulmonary blood flow in patients with cyanotic congenital heart disease and reduced pulmonary blood flow.

BCPA是上腔静脉或腔静脉的体静脉回流血分流到两肺的一种手术，这种手术连接可以增加肺血减少的紫绀型先心病的肺动脉血流。

The main pathological findings include a desquamative interstitial pneumonia-like reaction with intra-alveolar macrophages and numerous large multinucleated histiocytes that ingested inflammatory cells were admixed with macrophages.

GIP主要病理表现有脱屑性间质性肺炎样反应，即在肺泡腔内有巨噬细胞和大量的多核巨细胞聚集，位于肺泡腔内的多核巨细胞内可见被吞噬的炎性细胞，是GIP的特点。

A photonic crystal-air interface or line defect is utilized as a holophote or a partial reflective mirror to design a paralleled plane cavity, a single ring cavity structure and a multi-ring cavity structure. The method has simple design idea, good integration and wide application; by adopting the method, the self aligning photonic crystal lasers with different wave bands can be designed according to the luminescent characteristics of different materials; particularly, the utilization of semiconductor materials to design a light source of optical communication wave bands has more important practical value.

利用光子晶体-空气界面或线缺陷作为全反射或部分反射镜设计平行平面腔、单环形和多环形腔结构；该方法设计思路简单，集成性好，适用范围广，可根据不同材料的发光特性设计不同波段的自准直光子晶体激光器，特别是用半导体材料设计光通讯波段的光源器件具有更重要的实用价值。
