Cases healthy subjects served as control. In addition, density of glomerular matrix membrane and quantity of cell in glomeruli were measured with CMIAS image analysis system by computer. Global sclerosis, cellular crescents, fiber or fibrocellular crescents were measured with Memphis scope. Tubulointerstitial lesions were examined with semi-quantitative grades (including O-III grades).Results Compared to normal control, there was a significant increase of urinary TGF-betaK IL-6 and Col-lV levels in patients with IgAN (p. 01). There were also significantly positive correlation between the levels of urinary TGF-betaK Col-IV and density of glomerular matrix membrane ., interstitial fibrosisp.

采用酶联免疫吸附法测定尿TGF-β1(Transforming growth factor-β1)、尿IL-6(interleukin-6)和尿Col-Ⅳ(type Ⅳ Collagen)；采用免疫组织化学法检测肾组织TGF-β1、Col-Ⅳ表达；应用CMIAS多功能真彩色病理图像分析系统对肾小球基质基底膜面密度和细胞个数进行半定量测定；对球性硬化、节段硬化、细胞新月体及纤维或纤维细胞新月体所占肾小球百分数和肾小球IgA沉积免疫荧光强弱的判断采用Memphis法进行评分；肾小管间质病变程度采用光镜下半定量分级法(包括0-Ⅲ级)。

The attenuation values at unenhanced and enhanced CT of the tumor were also recorded. Results The 32 cases adrenal neoplasms included 9 cases with aldosterone-producing adenoma, 5 hydrocortisone-producing adenomas, 1non-functional adenoma, 5 cortical hyperplasies,4 pheochromocytomas,2 adenocarcinomas, 3 metastases, 1 fibroneuroma, 1 ganglioneuroma and 1 myelolipomas. Conclusion The characteristics on CT images are associated with the pathological feature in adrenal neoplasms.

The authors sug-gest that the decreased density of BDNF positive products in lamina II on the 3rd and 6th day was related with the degenerationof the nerve fibers and varicosities after section of the adjacent dorsal roots. On the 12th day, the remaining L6 dorsal roots un-derwent collateral sprouting compensatoryly and reestablished functional connection with target neurons.

作者认为3 d、6 d的减少主要与邻近背根节切除后，其神经纤维和膨体溃变有关；12 d时，保留的Ls背根逐渐侧支出芽，且与靶细胞再建功能联系，故脑源性神经营养因子阳性神经纤维和膨体数均趋于恢复。
