Objective To Investigate the factors affecting the post treatment fever in patients with primary liver cancer (PLC) undergone transcatheter arterial chemo embolization(TACE).Methods Seventeen clinical parameters of 102 TACE procedures were determined as independent variables, while the numbers of days running a fever after the procedure of the patients were determined as dependent variables. A multivariate stepwise regression analysis was performed to determine the factors that had affected the duration of fever. Results The factors that affected the fever after TACE were the dose of lipiodol used, ascites, using gelatin sponge(GS), serum albumin level, a history of fever, pre operative leukocyte counts and age. The volume of lipiodol used had played the most important role in affecting febrile time. Conclusions The amount of lipiodol used is the most important factor affecting the post treatment fever in patients with PLC undergone TACE with a tendency of intensification by using GS. The systemic state and the regional state of the liver before the treatments also play some parts in affecting the fever. Some frbrile cases are probably associated with potential infection. The lasting time of fever can be predicted approximately by building up a multivariate regresion equation.

Objective To investigate the effects of flumazenil and naloxone on scopolamine-induced impairment of spatial working memory in rats.Methods Forty pathogen-free SD rats weighing 160-200 g were randomly divided into 4 groups(n=10 each):group I control(group C);group IIscopolamine(group S);group III flumazenil+scopolamine(group SF)and group IV naloxone+scopolamine(group SN).Scopolamine 0.8 mg/kg was administered IP once a day for 3 consecutive days in group II-IV.In group SF and SN flumazenil 0.5 mg/kg and naloxone 2 mg/kg were administered IP respectively once a day for 3 consecutive days in addition to scopolamine.Thirty minutes after last IP administration,cognitive function was assessed using Y-maze.The animals were killed after cognitive function assessment and bilateral hippocampi Were isolated for determination of mAChRM1 mRNA expression(by RT-PCR)and detection of ChAT positive neurons(by immuno-histochemistry).Results Cognitive dysfunction developed in group S as compared with control group and was ameliorated in group SF and SN.The number of ChAT positive neurong and mAChRM1 mRNA expression were significantly decreased in group S compared with control group and were significantly higher in group SF and SN than in group S.Conclusion Flumazenll and naloxone can ameliorate the scopolamine-induced impairment of spatial working memory by improving cholinergic neuron function.
