Results There was not specificity of clinical symptoms in liposarcoma of the orbit, the major clinical aspects were intraorbital occupied lesion and local hyperaemia,swell and pain which was similar to an acute inflammation. Four different subtypes of liposarcomas could be observed in orbit.In past literature,myxoid was the most common subtype（14 cases,70%）,secondly subtype was well differentiated（3 case）,round cell and pleomorphic subtype were rare（each 1 case）.This case was well differentiated mixed component of round and pleomorphic lipoblasts.

结果：脂肪肉瘤临床表现为眶内占位和貌似急性炎症的局部红、肿、痛，无特征性的症状；病理分型4型，文献中报道以粘液样型最多见（14例，占70%）；次为分化良好型，3例；圆形细胞为主型及多型性各1例；分型不详2例；本例为分化良好型为主伴有圆形脂母细胞及多型性脂母细胞成分。

Pathogenesy is not identified. here are no evident specificness symptoms. nd it is hard to deal with diagnosis and therapy. Retrospective analysis are performed in 41 cancer of pancreas, with imageology and operation results. provide information for clinical operation and therapy.

胰腺癌早期常无明显的特异性症状，而恶性程度又较高，诊断和治疗较为棘手，本组病例回顾性分析41例胰腺癌，通过影像学表现与临床手术结果相结合，对其影像学特征加以分析总结，为临床手术术式的选择提供参考。

Using time frequency analysis and image processing the modulation of linear frequency-modulated signal is analyzed and using relatively non-ambiguity phase revaluation technique, the modulation identification of phase-coded signal is also studied.

脉内调制特征中采用了时频分析方法和图像处理的方法分析了线性调频信号，采用相对相位无模糊的方法分析了相位编码信号。

But in the 18 dead cases, there are 13 whose blood fiow velocity of end systolic stage are lower than those of end diastolic stage. Conclusion The blood flow velocity of patients with subtentorial brain injury or metabolic or diffused brain disease have no obvious change.

结果 浅昏迷患者的TCD表现无特征性改变，当出现中度昏迷或深昏迷时，颅内幕上结构损害患者TCD表现与文献报告相似，颅内幕下结构损害、代谢及弥漫性脑病患者大脑中动脉血流速度改变不明显，但死亡的18例病人中有13例出现了收缩期末血流速低于舒张期末血流速。

In moderate or deep coma patients, who have intracranial supratentorial injury, the TCD manifestations are similar to related documents. The blood flow velocity of middle cerebral artery of patients with subtentorial brain injury or metabolic or diffused brain diseases have no obvious change. But in the 18 dead cases, there are 13 whose blood fiow velocity of end systolic stage are lower than those of end diastolic stage.

this gets sick the clinical symptom not to have the characteristic value, the medical history has the reference value.the sphere focus of infection has the crecent moon in the phantom performance to draft, the air bronchial tube drafts, the corona drafts to this sickness has the prompt value, sends the tubercle to see the small empty shade to have the diagnosis value, if in the discovery meniscus cavity has along with the body posture change "in the hole the ball drafts", has the important diagnosis value to the lung aspergillomycosis.this gets sick the diagnosis needs the pathology and the bacteriology inspection.

本病临床症状无特征性，病史有参考价值。在影像表现上球形病灶有新月征、空气支气管征、晕征对本病有提示价值，多发小结节均见小空洞影有诊断价值，如发现半月形空洞内有随体位改变的&洞中球征&，对肺曲菌病有重要诊断价值。本病的确诊需病理和细菌学检查。
