AIM: to establish an animals model of pulmonary embolism caused by echinococcus granulosus (E.g)cyst fluid. METHODS: Cyst fluid were isolated from sheep liver . Twenty-one rabbits were randomized into 3 groups: group Ⅰ(saline group), group Ⅱ(clear cyst fluid group), group Ⅲ (sand-contained cyst fluid group). Operation was performed on each animal to place a femoral artery catheter and a femoral vein catheter. Saline, clear cyst fluid or sand-contained cyst fluid were given to rabbits at a dose of 3 mL/kg body weigh . Observations were then made at 10, 30, 60 minutes to determine the changes of MAP, blood gas and vaso-active substance. Then ECT scanning image was obtained .After observation, all animals were killed and the lungs were harvested for histological examination by light microscopy. RESULTS: Remarkable decline of PaO 2 , MAP and rise of TXB 2, 6-keto-PGF 1? were observed in group Ⅲ and group Ⅱ(P

Objective To investigate whether the bilateral nipple discharge with the background of hypothyroidism and pituitary tumor causes intraductal neoplasm. Methods Clinical data of 222 bilateral nipple discharge patients with hypothyroidism or pituitary tumor undergoing mammary ductoseopy (MDS) examination were analyzed. Those diagnosed as intraductal papilloma received surgery and pathological exam. 158 cases with inflammatory comedomastitis diagnosed by MDS received milk duct washing with gentamycin, dexamethasone and corresponding medical treatment. Results Among the 222 cases, 158 cases(71.17%) were diagnosed as inflammatory comedomastitis by MDS, 64 cases (28.83%) were diagnosed as intraduetal papilloma (64/222) by MDS and received operation,59 cases were pathologically diagnosed as intraductal papilloma,the other 5 cases were pathologically diagnosed as mammary duct ectasia. The pathological coincidence was 92.2% and no breast cancer was observed. 68.10% of inflammatory comedomastitis cases suffered from breast pain. There were no significant difference in the disease distribution of the ethnic groups. During pre-menopause period, the incidence of period neoplasia is higher in pituitary tumor than hypothyroidism; However, during the post-menopause the situation was vice versa. The color of niplle discharge is mostly milk-like in patients with pituitary tumor, while serous in patients with hypothyroidism. 71.19% of duct papilloma locate at the branch of the main duct. Conclusion The bilateral nipple discharge with hypothyroidism or pituitary are usually concomitant with intraduetal lesions. Mammary ductosopy is helpful to discover intraduetal neoplasia.

Objective To assess the risk factors of postphlebitic syndrome(PS)after deep vein thrombosis of the lower extremities. Method In this study,102 DVT patients managed by conservative therapy were recruited.Data including age,sex,etiopathogenesis,anticoagulation,pathogenesis, elasticstocking therapy,degree of lower extremity exercise,INR,WBC,PT%and FIB were analyzed by single factor analysis and COX analysis. Result PS developed in 67.60%cases,single factor analysis shows:sex(P=0.025),anticoagulation(P=0.000),elastic-stocking therapy(P=0.000),degree of lower extremity exercises(P=0.000),INR(P=0.033),WBC(P=0.012),PT%(P=0.000),FIB(P=0.002)are related to the occurrence of PS.COX regression shows that anticoagulation(P=0.011),the degree of lower extremity exercise(P=0.019),elastic-stocking therapy(P=0.000)are related to PS.Age (P=0.299),etiopathogenisis(P=0.838)and pathogenesis(P=0.2 17)are not statistically PS related.Conclusion DVT is a multi-factors related disease.Multivariant analysis revealed that elastic-stocking (P=0.000),anticoagulation(P=0.011)and the degree of lower extremity exercises(P=0.019)are related to the development of PS.

Objective To investigate the effect of hypertonic saline in the management of murine experimental severe acute pancreatitis (SAP) Methods SAP was induced in Wistar rats by intraperitoneal injection of 20% L Arginine Rats were divided into four groups ( n =12 in each group ); Healthy controls received intraperitoneal injection of distilled water of 5 ml/kg body weight initially Rats in the four groups were infused at 24 h and 48 h respectively at a dosage of 2 ml/kg body weight of distilled water in both healthy contrals, and SAP controls, of normal saline in group 3 and of hypertonic saline (7 5% sodium chloride) in group 4 Blood samples were collected at 48 h and 72 h after last injection for the measurement of plasma TNF ?、IL 6、 IL 10 All rats were sacrificed for histopathology of pancreatic and lung tissues at 72 h Results Animals that received hypertonic saline showed less pancreatic and lung damage than those resuscitated with normal saline Plasma levels of TNF ?、 IL 6 decreased significantly and plasma levels of IL 10 increased more significiently at 72 h after induction of SAP Conclusion Hypertonic saline resuscitation result in a significant attenuation of the systemic inflammatory response to severe acute pancreatitis
