Abstract］ Objective To identify the relationship between serum homocysteine and carotid artery atherosclerosis in patients with cerebral infarction and effects of foliate,methylcobalamin.

摘要］ 目的探讨脑梗死患者颈动脉病变与血清同型半胱氨酸水平的关系及叶酸、甲钴胺长期干预对其影响。

In the first group, photosensitizer was injected intravenously quickly before irradiation as in the previous treatment. In the second group, photosensitizer was injected intravenously slowly throughout the first 15min of irradiation. In the third group, hot fomentation was made on the treated area for 30min, then photosensitizer was injected quickly as in the first group.

3建立PWS组织光学模型，采用Monte carlo方法模拟了临床常用532nm激光在PWS组织中的分布特点，分析皮肤各层组织对其吸收的特点、组织结构(表皮黑色含量、病变血管深度等)以及治疗中氧含量变化对光能流率在PWS组织中分布的影响。

Objective:To analyse and summarize the CT appearances of posterior fossa tumors and its differentiations.

目的：总结分析后颅窝占位性病变的CT表现及其鉴别。

FLAIR is useful to fossa cranialis posterior disease and every cases should be done with it.

FLAIR对后颅窝病变具有较好的诊断价值，应作为常规应用。

When patients are monitored closely, many CNV lesions can be detected outside of the fovea and when they are relatively small.

当对病人的检查比较接近时，很多CNV可在中心凹以为的地方被找到，并且当时的病变也比较小。

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。

Methods The data of 16 cases of ureteral polyps were reviewed and discussed. 2 cases were treated with nephroureterectomy; 10 cases with local resection plus pyeloplasty or ureteral reimplantation; 4 cases with polyps resection plus basement fulguration.

回顾分析16例原发性输尿管息肉患者的临床资料，其中2例行肾输尿管大部切除术，10例行病变输尿管切除加肾盂成形术或输尿管再植术，4例行息肉切除加基底电灼术。

So unless fundus examination, otherwise the early retinopathy will not be found.

所以除非检查眼底，否则早期的视网膜病变将无法被发现。
