ABSTRACT
Objective:To explore the correlation between fibrinogen levels and chemotherapy effect of platinum drugs in ovarian cancer patients. Methods:Totally 91 ovarian cancer patients and 95 patients with benign ovarian tumor were involved in our retrospec-tive study, and the associations between preoperative fibrinogen levels and clinic pathologic parameters in the patients were analyzed. Results:High fibrinogen levels were observed in 36.26％ (33/91) of the patients with ovarian cancer ( >4.0 g·L-1), which was significantly higher than that in the patients with benign tumor(P0. 05). More importantly, no correlation was observed between high blood fibrinogen and CA-125 lev-els (P>0.05). Chemotherapy resistance was more in the patients with high fibrinogen levels than that in the other patients(P <0. 05). The OR value of high fibrinogen levels was 3. 571, 95％ CI was 1. 276-10. 000, which suggested high fibrinogen level is a dangerous factor for chemotherapy resistance. Conclusion:The study suggested that elevated fibrinogen level was a dangerous factor for chemotherapy response, which has a potential role in the poor prognosis of ovarian cancer patients independent of CA-125.
ABSTRACT
Objective To investigate the effect and the mechanism of parecoxib sodium pretreatment on permeability of blood-brain barrier in a rat model of focal cerebral ischemia-reperfusion injury.Methods Sixty male SD rats weighing 300g were randomly divided into 5 groups (n=12 each):sham operation group (group S);focal cerebral I/R group (group I/R);parecoxib sodium 5 mg/kg pretreatment group (group L);parecoxib sodium7.5mg/kg pretreatment group (group M);parecoxib sodium 10 mg/kg pretreatment group (group H) Middle cerebral artery occlusion models were made by reforming Longa suture method in SD rats.Thirty minutes before ischemia,rats in group L,M and H were injected with 5 mg/kg、7.5 mg/kg and 10 mg/kg parecoxib sodium through the internal jugular vein.Group S and group I/R received equal volume of normal saline.ELISA technique was used to determine the content of S100 β,TNF-α,IL-1 β in Plasma.The changes of cerebral water content and the Evans Blue exudation from brain capillaries were observed.Results Pretreated with parecoxib sodium (5mg/kg、7.5 mg/kg and 10 mg/kg),the content of S100 β,TNF-α,II-1 β in plasma were reduced.The cerebral water content and the EB in brain were reduced.Pretreated with parecoxib sodium 10 mg/kg,Longa scores were reduced.Conclusion Pretreatment with Parecoxib can protect blood-brain barrier against focal cerebral I/R injury by inhibition of the inflammatory reaetion.
