The mice inoculated with Coxiella burnetii intrana- sally developed interstitial pneumonia,while the primary pathological changes of mice inoculated intraperitoneally are granulomas in spleen and liver.2.The pathological changes became more severe followed the dosage increasing.3.Coxiella burnetii can be detected in spleen and liver at day 2 after inoculation.the lesion became more and more serious from day 2 to day 12.The characteristic changes were observed at day 7,and recovered at day 14. 4.The reticuloendothelial system are main target of Coxiella burnetii.The pathogen was detected in cytoplasm of monocyte -macrophages of spleen, liver, lung, and endothelioid cells of blood vessel. 5. Coxiella burnetii can be found in macrophages lysosomes by electron microscopy. Most of them are round or rod, and polymorphic shape can also be observed in different size.

结果：1、通过不同感染途径的实验证实，滴鼻感染的小鼠主要表现为间质性肺炎，而腹腔注射感染小鼠则以脾脏、肝脏肉芽肿为主要病变。2、通过不同剂量的感染实验发现，随着感染Q热立克次体剂量的加大，动物病变愈加严重。3、通过感染后不同时间的动态病理学观察发现，在腹腔注射后第2d的脾和肝脏即可发现病原体，主要脏器的病理变化从第2d到第12d逐渐加重，第7d动物的病变最典型，至感染后14d动物的受损器官已开始出现修复性变化。4、 Q热立克次体主要侵害机体的网状内皮系统，在感染小鼠的肝、脾、肺和外周血管单核巨噬细胞以及血管内皮细胞胞浆中查见病原体。5、透射电镜观察可见Q热立克次体主要位于巨噬细胞吞噬溶酶体内，呈多形性，多见圆形和杆状，大小不一。

Methods One case of epithelioid hemangioendotheloma was observed on hi-stopathologic characteristics and immunohistochemical staining with review of the literatures.

观察和分析1例子宫上皮样血管内皮瘤病理形态特征和免疫组化标记，并结合文献复习，总结子宫上皮样血管内皮瘤临床病理学特点和鉴别诊断。

Furthermore, the index-evaluated angiogenesis has a significant correlation with microvascular density. So contrast-enhanced ultrasound can help predict prognosis and select treatment plan of anti-angiogenic therapy and exairesis et al.

同时其反映肿瘤血管的指标与肿瘤微血管密度具有较高的相关性，从而为预测预后及抗肿瘤血管生成的疗法、手术切除等治疗方案的选择提供重要的依据。

Meanwhile the lung tissue slide was prepared for electron microscopic observation at 180 minutes after reperfusion.Result: HO-1 expression was upregulated in two groups in the pulmonary endothelial cells,part of pulmonary vascular smooth muscle cells,extima of vessels and epithelial cells of airway,the absorbance was 0.148±0.013,0.158±0.012,respectively.The Shenmai injection group showed higher absorbance than those of the IRI group( P .01),lower W/D and IAR values than those of the IRI group( P .01) significantly and lighter abnormal changes of the lung tissue in morphologically than those of the PIRI group.

结果：HO-1在I-R组、SM组肺血管内皮、部分血管平滑肌、外膜层及部分气道上皮均有阳性表达，原位杂交的平均吸光度分别为0.148±0.013，0.158±0.012，SM组HO-1的表达水平明显高于I-R组( P 。01)，W/D，IAR值显著低于I-R组( P 。01)，肺组织形态学异常改变轻于I-R组。

The extracerebral CCM group,completely different from the intracerebral one, presented elastic and thick-wall vessel.

脑外组CCM表现为弹性较好的厚壁血管，脑内组为弹性较差的薄壁血管。
