病变

①Headache at different levels was the commonest symptom for benign and malignant lesions. The visual loss was another common symptom. It is important to realize the relationship between visual symptom and space-occupied lessions in sphenoidal sinus and sellar area;②Imaging study is very important for the diagnosis of the lesions in sphenoidal sinus and sellar area;③It is helpful to do needle-aspirating biopsy under endoscopy to confirm the pathologic diagnosis.

①良恶性病变均以头痛为第一常见症状，眼部症状为第二常见症状，掌握眼部症状与蝶鞍占位的关系对及早诊断意义重大；②影像学检查对此区域病变的发现和诊断起着重要作用；③内窥镜的应用及镜下穿刺活检亦对诊断十分有帮助。

Meanwhile, there was a negative correlation (all P.01) between HRV parameters SDNN、SDANN、SDNNindex、 rMssd and Gennisiscore、the quantity of coronary artery involved、 the percentage of coronary artery stegnosis.

所有病例的心率变异指标（PNN50除外）与反映冠脉病变严重度的冠脉病变支数、冠脉狭窄百分比、Gennisi评分存在明显的负相关关系(P.01)。

The expressions of VEGF mRNA in renal cortex in B and group C increased greatly compared with A group at 8th week(P.01), And the expression was decreased more in C group than that in B group at the 8th week;④The light microscopes results showed that no pathological changes in group A; pathological changes were much obvious in group B:glomerular capillary lumen tumbling,lumens blocked,mesangial region widened,basal lamina thicking,mesenterium base inceased,the volume of glomerulus become large,cell population increased,renal tubule vacuolization, renal interstitium was infiltrated by lots of lymphocyte and mononuclear macrophage; pathological changes in group C was light,only see glomerular capillary lumen lightly stegnosis,few lymphocyte infiltrating.

免疫组化结果显示第8周B组大鼠肾皮质VEGF蛋白含量较A组显著增加(P.01)，C组VEGF含量较B组有明显减少(P.01)，C组较A组表达量仍然增加(P.01)；③第8周B组肾皮质VEGF mRNA表达较A组有明显上调(P.01)，与B组相比，辛伐他汀可以明显减少C组肾皮质VEGF mRNA表达；④光学显微镜下A组肾小球毛细血管腔均匀一致，无狭窄，肾小管-间质无炎症细胞浸润。B组则病变较明显：大鼠肾小球毛细血管袢塌陷，管腔闭塞，系膜区增宽，基膜增厚和系膜基质增多，肾小球体积增大，出现玻璃样变；肾小管尤其是近区小管肿胀、变性、空泡形成，肾间质可见大量淋巴细胞和单核巨噬细胞浸润。C组病变较轻，可见肾小球毛细血管管腔轻度狭窄，肾小管-间质见少量淋巴细胞浸润。

The vessel diameter, vessel area, diameter of reference vessel rate of stenosed area and lesion length detected by three-dimensional reconstruction coronary angiography and QCA were compared.

分析比较冠状动脉3D重建和QCA传统平面图像对靶病变管腔直径和面积、参考血管直径、面积狭窄率、病变血管长度的测量值。

Results The shape, size, location, and the relationship with the neighboring structures of the lesions were well displayed stereoscopically in all 16 patients with craniocerebral disease.

结果 16例颅脑病变患者均立体显示了病变的形态、大小、位置以及与周围结构的关系。

Results MPR images demonstrated the details of the bones and joints, and displayed the density, shape and range. VR reconstruction showed the lesion directly and stereoscopically. MIP and SSD were better in showing the location, range and surrounding soft tissues.

结果 MPR对骨关节疾病细节显示良好，可以多平面观察骨密度、形态、范围，VR三维重建对病变观察直观、立体，MIP、SSD很好地显示病变的位置、范围及周围软组织情况。
