Results:① 890 lesions which were mostly located in lentiform nucleus（40.8%）, then in corona radiata, dorsal thalamus, internal capsule, caudate nucleus and pons were detected by MRI in 120 cases.

结果：①120例行MRI检查患者共发现病灶890个，最多见于豆状核（占40 。8%），其次为放射冠、丘脑、内囊、尾状核、桥脑，可为圆形、椭圆形、条索状病灶。

Abstract］ objective to explore the failure causes of mastoidectomy and precautions.methods the operation findings of 37 cases who underwent revision mastoidectomy from 1995 to 2005 were analyzed for causes of the primary procedures and revision mastoidectomy failure.results original symptoms disappeared.all cases achieved a dry ear after mastoidectomy 1～3 months.conclusion causes of failure of mastoidectomy include unfamiliarity with regional anatomy,absence of skill of surgeons,unadequate opening of mastoidale,and clinical experiences.each of these can result in residual lesion and inadequate drainage.some exceptions can also result in reoperation.to resect the pathological changes tissue thoroughly,to remain good drainage after operation,to manage some execptions are keys to prevent reoperation.

目的 探讨乳突根治术不能干耳原因及预防措施。方法对我科1990~2005年收治的37例乳突根治术不能干耳患者的再次乳突手术所见进行分析，并行二次乳突根治术。结果术后1～3个月患者原有症状消失、干耳。结论乳突根治术失败原因主要是术者中耳乳突解剖不熟、基本功不过硬、临床经验不足导致病灶残留、引流不畅和乳突尖开放不够及某些特殊情况所致。术中彻底去除病灶，保证术后引流通畅及特殊情况的处理，是防止二次手术的关键。

Recurrent lesions in the cortex and subcortical white matter of temporal, parietal, and occipital lobe on MRI might provide clues for diagnosis of MELAS syndrome. DWI might show lesions earlier than T2WI in MELAS syndrome similar to cerebral infarction.

MRI反复颞顶枕叶皮质及皮质下白质病灶可为临床诊断提供帮助，与在脑梗死诊断中的作用类似，弥散加权成像可能会更早地显示病灶。

Upper gastric pain and melena presented frequently;protrude type lesions larger than 3cm were frequently localized in cardiac parts under gastroscope; poorly differentiated adenocarcinoma accounted for 47.58%;lesions larger than 3cm possessed higher probability of invading to placenta percreta and metastasis to lymph nodes;liver was the most common organ of metastasis by gastric cancer.

内镜下3厘米以上，隆起型病灶多见，好发于贲门部，低分化腺癌最常见（占52.47%），直径大于3厘米病灶侵及浆膜层及淋巴结转移率高。胃癌最常转移到肝脏。

Single joint was involved in two and multiple lesions in five of them,including the knees,elbow,wrist,phalangeal joint,metatarsophalangeal joint,metacarpophal...

根据病变严重程度分别采用关节抽吸冲洗类固醇注射、关节镜下病变清理术、痛风病灶清除术、刮除植骨术、Keller's手术及关节融合术治疗痛风病灶。
