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。

Research results indicate that varicosity can be treated by means of endovenous thrombus formation, blood vessel wall damnification and vessel enclosure induced by light absorption of haemoglobin irradiated by semiconductor laser.

研究结果表明：半导体激光进行腔内静脉照射，由于血红蛋白对光的吸收，可以引起静脉腔内血栓形成、血管壁损伤、血管闭合，实现对静脉曲张的治疗；激光照射导致静脉腔内血栓形成，与血栓性静脉炎的形成机制不同，并没有影响全身凝血功能。

The in-stent restenosis and target vessel new lesions were observed at 12 months after the procedure by coronary angiograph (restenosis was defined as loss of lumen diameter ≥ 50%; new lesions defined as loss of lumen diameter ≥ 30%).

置入后12个月复查冠状动脉造影，支架内及支架两端5 mm范围内管腔直径丢失≥ 50%为支架内再狭窄，其他部位新出现的病变使管腔狭窄≥ 30%为新生血管病变。

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。

Hemarthrosis and laceration of the disc and the attachment were also observed. 7 days later, the hemarthrosis was seldomly seen. Effusion was seen in some joints at 2 weeks. At 1 month posttrauma, the severely damaged structure of the two joints in one animal was found. We could find the loss of the disc and the cartilage of the condyle. Effusion also existed.

伤后1月，可见有一侧关节盘完全破坏，髁突软骨层消失，关节腔内渗出；对侧关节结构紊乱，关节盘及髁突明显变形、不规则等变化。3月后，多数关节结构基本正常，但关节内的破坏性改变仍然存在，关节内可见较明显的裂隙或囊状改变，软骨组织变薄，关节盘松解，关节腔扩张等变化。

BACKGROUND: Implantation of artificial joint of bone cement can result in long-term blocking of recipient site medullary canal and blood vessel lesion, and lead to changes in intraosseous pressure and bone blood flow of distal femoral shaft.

背景：骨水泥固定型人工关节假体骨腔内的植入必然涉及受区骨髓腔的长期闭塞和髓内血管的破坏，由此而产生的髓内压和血流的变化是材料本身的影响所致，很有研究价值。

Results While the ES lumen and perisaccular region were infiltrated with mononeuclear-phagocyte at the 3rd day post-vaccination, plasmocyte and lymphatic cells become the predominant infiltrating cells in the ES at the 7th day. The KLH in the ES lumen were phagocytized at the 3-7th day post-vaccination. S-phase cells and IgG positive cells in ES increased markedly in the 3rd day and 7-14 days post-vaccination respectively with similar localization.

结果 内耳受抗原刺激后3 d内淋巴囊囊腔和囊周区域出现单核吞噬细胞浸润，7 d内淋巴囊的浆细胞和淋巴细胞大量增加；3～7 d内淋巴囊囊腔KLH被吞噬，同时S期细胞和IgG阳性细胞逐渐增多，二者的出现部位相似。

5Ns. The peak position of N band emission as well as the distinct emission region slightly moves towards the open end of the cylindrical cavity, and this does not happen to O band emission. Radiation transport efficiency of 6% is obtained for the φ400×1200um cylindrical cavity heated by x-ray source with radiation temperature of 118 eV.

从时间分辨的X光强度轴向空间分布来看，在较长时间（约1～1.5ns）内，O带X光在整个观测缝对应的轴向范围之内均有较大的辐射强度，在X光强度空间分布的变化过程中，其强度峰值的空间位置基本不变；而对N带X光，则只在较短时间（约0.5ns）内，在整个观测缝对应的轴向范围之内可观测到X光辐射，但只在靠近输运源约300μm的范围内有较强发射，在柱腔末端600～700μm范围之内的辐射则很弱，N带X光辐射轴向空间分布曲线的峰值位置在朝柱腔末端的方向移动，移动量大约为130～250μm。

Protein disulfide isomerase is one of main retention proteins in ER, which is an abundant protein in luman of the ER especially in secretory cells.

蛋白质二硫键异构酶是内质网腔内的主要驻留蛋白之一，在分泌细胞的内质网腔中含量非常丰富，其主要功能是催化细胞内分泌蛋白和膜蛋白新生多肽的二硫键形成。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
