AIM To test the hypothesis that intravenous liposomal prostaglandin E 1 (Lipo PGE 1) would attenuate reperfusion injury in a rabbit ischemia reperfusion model. METHODS Twenty four open chest rabbits were randomized to receive a 10 minute intravenous infusion of either liposome diluent (placebo), free PGE 1 (2 ?g?kg -1 ), or Lipo PGE 1(2 ?g?kg -1 PGE 1) after 60 minutes of left anterior desending (LAD) ligation just before reperfusion. Carotid arterial pressure and electrocardiogram were monitored and recorded continously throughout the whole experiment. After 2 hours reperfusion, infarct size and region at risk were measured by postmortem dual dyes with triphenyl tetrazolium chloride (TTC) and Evans blue. Myocardial leukocyte infiltration by myeloperoxidase (MPO) assay was performed. RESULTS Infarct size as a ratio of weight of infarcted tissue to weight of region at risk (MI/RISK) was significantly reduced with Lipo PGE 1 32.20%?4.70% compared with PGE 1 42.09%?6.93% or placebo 44.57%?5.46% ( P

Objective To evaluate the effects of temperature of the irrigation fluid on body temperature and cardiovascular performance during transurethral surgery. Methods 87 cases were randomly divided into two groups according to the temperature of irrigation fluid used: the ambient (21~ 24 ℃) and the isothermic (35~36 ℃). Body temperature, blood glucose, ECG, HR, SaO 2, cardiac output (CO), mean arterial pressure (MAP) and systemic vascular resistance (SVR) were monitored during the transurethral surgery. Results Body temperature was decreased 2.1 ℃, MAP elevated, CO decreased and SVR increased in the ambient group, while body temperature was decreased only 0.3 ℃ and cardiac performance was maintained relatively stable in the isothermic group. Conclusions Hypothermia, resulted from the use of large amount of low temperature irrigation fluid during transurethral surgery has detrimental effects on body temperature and cardiovascular performance. Isothermic irrigation fluid would stablize the cardiovascular performance and so increases the safety of transurethral surgery.

ObjectiveTo evaluate clinical-pathological features, diagnosis and therapy of gestational trophoblastic tumor (GTT) misdiagnosed as ectopic pregnancy. MethodsFrom 1999 to 2003, a total of 13 patients with GTT misdiagnosed as ectopic pregnancy were retrospectively analyzed. ResultsThe main symptoms were amenorrhea, abdominal pain, irregular vaginal bleeding. Serum beta-human chorionic gonadotrop in(hCG) was measured in 10 patients. Eight had hCG values above 10 000 IU/L; 3 had hCG values above 50 000 IU/L. The lesions of GTT misdiagnosed as ectopic pregnancy were fallopian tube, horn of uterus, peritoneal cavity, greater omentum, recto-uterine pouch. According to standards of the International Federation of Gynecology and Obstetrics(FIGO) the 13 patients were categorized as 6 of stage Ⅰ, 2 of stage Ⅱ, 3 of stage Ⅲ and 5 of stage Ⅳ. Histologically they included 10 cases of choriocarcinoma and 3 of invasise mole. All patients were treated by complete surgical resection combined with subsequent adjuvant chemotherapy. ConclusionsMisdiagnosis leads to delay in therapy with resultant increased morbidity of GTT.Analysis on serial hCG is helpful to differential diagnosis between ectopic pregnancy and GTT.
