While diagnosing and treating SARS cases, doctors should rule out the possibility of other lung diseases with similar clinical manifestations, such as primary bacterial or fungal pneumonia, pulmonary tuberculosis, lung tumor, non-infective interstitial lung diseases, pneumonedema, atelectasis, pulmonary embolism, pulmonary infiltration with eosinophilia, and pulmonary agents.

答：在非典型肺炎的诊断治疗过程中，首先要注意排除原发细菌性或真菌性肺炎、肺结核、肺部肿瘤、非感染性肺间质性疾病、肺水肿、肺不张、肺栓塞、肺嗜酸性粒细胞浸润症、肺血管炎等临床表现类似的肺部疾患。

Methods: Collect the English and Chinese investigation literature for pancreatic gland primarily occupation which were published and cited by MEDLINE and the core Chinese academic journals, with pathologic diagnosis. We collected 21 piece of writing, and reconsolidate these literatures, calculate the sensitivity, specificity, degree of accuracy, positive predictive value and negative predictive value, and 95% confidence interval.

收集自1994年以来PET应用公开发表的能被MEDLINE引用或中国科技核心期刊的中英文胰腺原发占位研究文献，要求这些研究文献需有病理诊断结果，共收集到21篇，将文献重新合并，按国内、国外以及总体合并计算其灵敏度、特异度、准确度、阳性预测值和阴性预测值，并计算其95%可信区间。

The lower neck node area and supraclavicular fossae were irradiated with the conventional technique by anterior field. results with a median follow up of 12 months(range 2~32 months), 6 patients died(4 died of distant metastasis), 5 patients relapse in the primary site, 2 patients relapse in the neck and 16 patients showed distant metastasis.

结果 中位随访时间12个月（2～32个月）。6例死亡（其中4例死于远处转移），5例原发灶复发，2例颈部复发，16例远处转移。1年和2年的总体生存率、无局部复发生存率、无区域进展生存率和无远处转移生存率分别为100%，94.6%；98.4%，91.4%；99.1%，97.9%及91.9%，85%。n分期是影响无远处转移生存率的预后因素（p＝0.04）。

Osteosarcoma is one of the commonest primary malignant tumors of bone. It metastasizes fast, and has a high death rate.

骨肉瘤是原发于骨的肿瘤中最常见的一类恶性肿瘤，转移快，死亡率高。

Methods: The immunohistochemical expression of IGFBP-2 protein was measured by image analysis in 35 surgically resected specimens of gastric cancer (include normal mucosae, primary tumors and metastases of lymph node).

对35例外科切除胃癌标本的正常粘膜、肿瘤原发灶和淋巴转移灶进行IGFBP-2蛋白的免疫组化染色，并用计算机图象分析软件测定其积分光密度。

It would be useful to find out the pathologic diagnosis of the original tumor resected 1.5 years ago.

找到一年半以前切除原发肿瘤的病理诊断是有用的。

Objective To study the value of imaging characters in diagnosing primary malignant tumors of chest wall.

摘 要］目的：探讨胸壁原发恶性肿瘤的影像学特点对其定性的价值。

Objectives The perioperative and microsurgical treatment of primary tumors in lateral ventricles were analysed in order to improve clinical results.

摘要］ 目的对原发于脑室内肿瘤的围手术期处理及显微外科治疗进行探讨，旨在提高该类肿瘤的临床疗效。

Both plain and enhancement CT scannings were made in 48 cases,8 cases with contrast CT and 4 cases with plain CT only.60 cases with axial view were scanned,and 26 cases with coronal and axial view.

结果 CT对鼻咽癌的原发部位，浸润范围、途径和颈淋巴结转移情况显示较佳。横断面 CT扫描和冠状面 CT扫描联合应用可以提高鼻咽癌 CT诊断的准确性。

The clinical therapeutic strategies were changed in 22 cases due to the results of PET/CT,and the influence rate of PET/ CT was 28.6 %(22/77).Conclusion PET/CT can detect the primary lesions, recurrence and metastasis of gastrointestinal tumor with high sensitivity and accuracy. 18F-FDG PET/CT imaging has increased accuracy of the diagnosis, staging, restaging for gastrointestinal tumor.

PET/CT能准确、灵敏地检测胃肠道肿瘤原发病灶、转移以及复发病灶，对临床治疗决策有重要影响。18F-FDG PET/CT显像对胃肠道恶性肿瘤的分期、术后再分期诊断有较高的临床价值。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
