Methods A retrospective analysis was performed for images of CT,MRI and DSA of 12 patients with intracranial venous angiomas.In all cases,7 cases male,5 cases female,age ranged from 8 years old to 72 years old.All patients underwent the examinations of CT,MRI and/or DSA.Results All 12 patients had single lesion.In these cases,there were 6 cases （50%） located in cerebella,6 cases （50%） located in cerebra including 3 cases （25%） in lobus frontalis and 3 cases （25%） in lobus parietalis.Most patients had slight clinical symptoms and were detected the lesions accidentally when they were examined for other diseases.Compared the imaging features of CT,MRI and DSA,conventional CT scan was negative,but there were characteristic images which was "dendritic" sign in contrast-enhanced CT and MRI,and typical findings of "caput medusae"sign in venous phase of DSA.

结果 颅内静脉血管瘤均为单发；6例（50%）位於幕下小脑实质内，6例（50%）位於幕上额叶（3例25%）、顶叶（3例25%）脑实质内；患者临床症状轻微，多为合并其他病变检查时偶然发现；CT、MRI及DSA的影像比较，CT平扫为阴性，CT增强扫描与MRI平扫呈特征性表现，即树枝征，DSA静脉期可见典型表现蛇头征。

In patients with CPS but without GTS, the focus was mostly located in unilateral temporal lobe, esp, in the medial temporal lobe or the limbic system if the ictal and the interictal EEG was normal, but in those patients with CPS and GTS, the focus was located in the lateral temporal parietal lobe or temporal parietal-occipital areas.

CPS不继发全身性发作的患者，病灶多局限于一侧颞叶，如发作期和发作间期脑电图均正常，更应考虑病灶位于颞叶内侧面，或边缘系统；CPS继发GS的患者病灶多位于颞叶外侧面与顶、枕交界区。

Methods After left lateral segmental partial hepatectomy or right anteroinferior partial hepatectomy,the left external inferior or the right anteroinferior hepatic duct was exposed,and intrahepatic chlangio-jejunostomy was performed.

切除部分肝左外侧叶，解剖出左外下段支肝管或切除右前叶下段部分肝组织，解剖出右前下段支肝管与空肠行Roux-y吻合，在有效减黄率，合并症，黄疸再发率及生存期等方面与三组非外科胆管引流方法PTBD、ERBD、EMBE进行对照比较。

ResultsIdiopathic nocturnal frontal lobe epilepsy has distinctive clinical seizure characteristics. The onset age is younger than 20 and the ratio of male cases to female cases is 2 to 1. The most notable clinical characteristics are nocturnal clustered postural or dystonic seizures and complex motor activities, with 14% of the patients have epileptic family history. The interictal routine EEG of 22.9% and active EEG of 28% cases in wakeness and 38% cases in sleep showed frontal lobe epileptiform discharge while the ictal EEG of 66.7% cases showed frontal lobe epileptiform discharge. Drug therapy is effective in 80% cases with 30% completely controlled.

结果 特发性夜间额叶癫痫具有特征性的临床发作特点，大多数于20岁之前起病，男女比例2：1，以夜间成串的偏转性、姿势性强直及过度运动发作为最显著的临床特征。14％有阳性癫痫家族史。22.9％清醒发作间期常规脑电图及28％清醒发作间期动态脑电图可见额叶癫痫样放电，38％患者的睡眠发作间期动态脑电图可见额叶癫痫样放电，66.7％患者的发作期脑电图可见额叶癫痫样放电。80％药物治疗有效，30％可完全控制。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
