Primary angiosarcoma of breast is a rare malignant tumor,about 0.05%of all the malignant tumor of breast.The heteromorphism,such as endothelioeyte,blood vessel even caryocinesia,distinguishes this disease from other carcinoma of breast.Positive ratio of endothelial cell makers(Anti-FⅧR,CD3 1,CD34,UEA-1,et al)and VEGF is relatively high.Besides fine needle aspiration and biopsy,ultrasound,X-ray and MRI maybe helpful to di agnosis.Surgery is certainly the first choice to care this disease.The effect of chemotherapy,radiotherapy and tar geted therapy is still in research.

Objective To study the effect of FK506 pretreatment on endotoxin shock induced by LPS. Methods 155 mice of the Kunming strain were randomly divided into LPS group (n=80) and LPS|FK group (n=75). An endotoxin shock model of mice was reproduced by an intraperitoneal injection of LPS (25ml/kg for each mouse). Beginning from 2 days before the reproduction of the model, each mouse of the LPS+FK group were given 20ml/kg of FK506 q 12 h, by gastric gavage while animals of the LPS group were given an equal amount of 0.9% sodium chloride solution in the same way. The survival time of 20 mice of the LPS group and 15 mice of LPS+FK group was observed. 10 mice of each group were sacrificed at 0,0.5,2,4,6 and 8 hours after the injection of LPS, respectively. Blood samples were collected and serum TNF-? and IL-1?, contents, and activiry of ALT and AST were determined.
