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。

According to the rudiment epidemiological investigation in our country. The ratio of male to female is 1:3. RA regardless of for traditional Chinese medicine or Western medicine, is still a kind of difficult treat disease. Major is the cause of this disease with pathologyical mechanism lack all-sidely thorough understanding, and lack peculiarness laboratory index in the early stage of disease, so early diagnosis is very difficult.

我国经过初步流行病学调查，RA发病率为0.3～0.5%，男女发病比例约为1：3，西医对本病病因和发病机制认识尚欠清楚，缺乏具有针对性的特效药物；虽然据临床报道中医药对RA具有良好的治疗效果，但由于RA的中医证候分类繁多，目前尚无统一证候分类标准，临床疗效观察缺乏可重复性，严重制约了中医对RA研究的深入开展。

Results:pedunculated omentum majus-cirded trachea transplantation ensured an early re-establishment of blood circulation of transplanted trachea and maintenance of its normal animate states; allogeneoilc transplantation of trachea activated bodys immune mechanism. resulting in a chronic process of rejection and finally leading to progressive necrosis of transplanted trachea tissues: chondroregeneration occurred at every period under perichondrium after transplantation. and the degree of regeneration was related with favorable blood circulation; the emplogyment of a supporting tube in trachea,under the condition of favorable re-establishment of early blood circulation, could preventgranulation tissue hyperplasia and keep trachea cavity unobstructed.Postgraduate Ding XiaoQuan Directed by-Lin LeShen

结果 带蒂大网膜包绕移植段气管行腹腔移植，早期重建了移植段气管的血液循环，保证了移植气管的早期成活及维持其正常生机状态；同种异体气管移植所激发机体的免疫机制，引起一个慢性排斥反应过程，导致移植段气管组织进行性坏死；软骨再生存在于移植后各个时间段，其再生程度与良好的血液循环有关；气管内支撑管的应用可防止肉芽组织增生堵塞管腔，从而保证气管管腔通畅。

In this paper, problems of trend test in clinical experiment are studied mainly by the statistical inference method under order restriction. The ori- gins of order restricted statistical inference are usually dated back to the early 1950s. At about the same time, a number of researchers started working inde- pendently on similar problems. The field developed rapidly during the 1960s and early 1970s and formed the more perfect theory of estimation and test- ing.

In order to make clear the Pchlide reduction mechanisms of early development of plant seedling, the changes of Pchlide and Chlide during early development of the seedling of Phaseolus radiatus under different treatments using light and antibiotics were analyzed.

为了探讨被子植物幼苗发育初期Pchlide还原机制，本文采用不同波长的光照和抗生素处理，分析了光照诱导绿豆黄花幼苗发育初期Pchilde和Chlide的变化以及抗生素对Pchlide和Chlide的变化的影响。

At the early stage of HIRBD, the Toll-like receptors may induce NF-kB activation, leading to the coordinated induction of multiple genes, which is involved in inflammatory, apoptosis and cell proliferation. Genes induced by NF-kB are responsible for the physiopathological process of early brain damage in neonatal rats with HIRBD.
