Results (1) 6 cases of Tuberous Sclerosis. Diffused subependymal nodular calcification lesions were found in all cases on unenhenced CT. 4 patients are 2 pairs of mother/child relationship. Both of the two mothers are found to suffer from renal angiomyolipoma.(2)1 case of neurofibromatosis showed abnormal spinal canal: scoliosis of thoracic and lumbar spine, concave change of vertebral posterior border. Bilateral renal hypogenesis was found in this patient. Diffused hyper-density lesions were found in kidney and fatty accumulation was found in back skin.(3)6 cases of Sturge-Weber syndrome. On unenhenced CT, curving and strip-shaped calcifications were found along the parietal and occipital gyrus.

结果 ①结节性硬化6例，所有病例CT平扫见两侧脑室室管膜下多发小结节状高密度钙化灶，其中4例为两对母子关系，并见两位母亲合并有肾脏错构瘤，；②神经纤维瘤病1例，MRI表现为椎管异常，胸腰段脊柱侧弯，椎体后缘呈明显的切凹改变；伴有双肾发育不良，CT示肾内多个高密度影，背部皮肤多量脂肪堆积，③脑颜面血管瘤综合征6例， CT可见顶枕部沿脑回分布的弯曲的条状高密度钙化，部分延伸致侧脑室内，增强后见病灶内有扭曲的条状和结节状明显强化的血管影；④小脑血管瘤病4例，影像学表现为小脑内大囊、小结节样占位性病变。

Histological analysis From day 14 after the operation, osteoblast-like cells appeared in clusters adjacent to vascular sinuses on either side of the fibrous interzone.

It can be said thatblood stasis is the main pathology of DN,which is in line with Chinese medicine in "invalidism must accompany with blood stagnation""invalidism develop into collaterals" The view of blood stasis also match the modern medical point of hemodynamics changes and capillaries disease in patients with DN,such as increased hemorheology general index,blood viscosity and lipids, reduced kidney blood flow,platelet aggregation,sclerosis of blood vessels, renal microcirculation disturbance,even hypercoagulability.

可以说，瘀血阻络是糖尿病肾病的主要病机，这既符合于中医"久病必瘀""久病入络"的学术观点，也与现代医学认识的糖尿病肾病患者血液动力学和肾脏微血管病理学实验中，血液流变学的指数普遍升高、血浆粘度增加、血脂增高、肾血流量减少，血小板聚集、血管硬化，肾微循环障碍，甚至出现高凝状态的研究相当吻合。
