目的:探讨肝脏假性淋巴瘤的MR表现及其相关病理基础。方法:回顾性分析6例经病理证实的肝脏假性淋巴瘤的MRI及其临床资料,MR图像分析内容包括病灶的数目、部位、大小、形态,边界,病灶平扫信号特点,动态增强特征等。结果:6个病例共7个病... 目的:探讨肝脏假性淋巴瘤的MR表现及其相关病理基础。方法:回顾性分析6例经病理证实的肝脏假性淋巴瘤的MRI及其临床资料,MR图像分析内容包括病灶的数目、部位、大小、形态,边界,病灶平扫信号特点,动态增强特征等。结果:6个病例共7个病灶,5例单发,1例含2枚病灶;7枚病灶均呈类圆形结节,平均大小为1.9cm,MRI平扫T1WI均为低信号,T2WI2枚略高信号、5枚呈中等高信号;DWI呈不均匀高信号;动态增强7枚病灶呈“快进快出”强化模式;6枚病灶表现为不规则厚环形强化;1枚病灶表现为不均匀强化;2枚病灶外见尖角状强化并向外延伸;1枚病灶内可见血管穿通征。6例病例肝门及腹膜后均未见淋巴结肿大、未见腹腔积液,未见远处转移。结论:肝脏假性淋巴瘤临床罕见,体积较小,多呈类圆形,MRI具有一定的特征性表现,有助于术前诊断及鉴别。 展开更多

ObjectiveTo investigate the effect of total flavones from the leaves of Choerospondias axillaris (TFLCA) on the immune function of normal mice and to provide the experimental basis for the reasonable application of C. axillaris.MethodsThe carbon clearance method, cutaneous delayed hypersensitivity reaction method, serum hemolysin method, and index of immune organs were used to study the effect of TFLCA on the immune function of mice.ResultsTFLCA could enhance the phagocytic function of mononuclear macrophage and the cutaneous delayed hypersensitivity reaction of mice, and increase the content of hemolysin antibody and the thymus index in mice.ConclusionTFLCA could improve the celiac macrophage activity and specific immunity of mice, and TFLCA, consisting with the total flavones of Choerospondiatis Fructus (TFCF), has the effect on the immune function of mice. So both TFLCA and TFCF have the regulatory effects on the immune function of mice. 展开更多
