ABSTRACT
Objective To investigate the protective effect of a COX inhibitor,flurbiprofen (Flurb) on hepatic ischemia/reperfusion (IR) injury in rats and the action mechanism.Method C57BL/6 mice were randomized into sham,IR and Flurb (4 different doses) groups.The model of segmental (70％) warm hepatic ischemia was established in IR and Flurb groups.Flurbiprofen of different doses (5,7.5,10 and 15 mg/kg) was injected via the tail vein 20 min before ischemia.At different time points after reperfusion,liver cell necrosis and apoptosis were evaluated by HE and TUNEL staining.The COX and inflammatory cytokine gene expression was detected by using realtime PCR.Liver mitochondria were separated and mitochondrial permeability transition (MPT) pore sensitivity was examined by using swelling assay and fluorescence spectrophotometry assay.Result In flurbiprofen groups of different doses,the serum AST and ALT levels were significantly decreased at 6 h after reperfusion as compared with IR group.Moreover,10 mg/kg Flurb pretreatment significantly inhibited the mitochondrial permeability transition (MPT) pore opening,and thus alleviated liver cell damage and prevented mitochondria-related cell death and apoptosis by inhibiting COX-2 and inflammatory factor genes expression such as IL-1β,IL-6 and TNF-α.Conclusion Flurbiprofen protects mice from hepatic I/R injury possibly by inhibiting mitochondrial permeability transition and IL-1β,IL-6 and TNF-α expression,which may provide experimental evidence for clinical use of flurbiprofen to protect liver function in surgical settings other than its conventional use for pain relief.
ABSTRACT
0.05).The frequency of Pp genotype of ER? gene was higher in female SLE patients than that in healthy control(P0.05).Conclusion The frequencies of X and P genotype were not significantly increased in Chinese female patients with SLE,but the Pp and ppXx genotype of ER? gene may be associated with the female SLE patients in analysis of restriction enzyme digestion.
ABSTRACT
Artery cannulation is one of the clinical skills that should be mastered by the internships of anesthesiology. In consideration of its invasiveness,teachers should carry out the clinical teaching strictly and patiently,and assist the internships to establish a correct opinion on clinical practice. We should train the internships step by step,improve their success rates on artery cannulation and avoid complications as far as possible.
ABSTRACT
Objective To investigate the related factors of encephalopathy following orthotopic liver transplantation (OLT).Methods The clinical data of 128 patients who underwent liver transplantation consecutively between October 2001 and October 2003 were analyzed retrospectively by SPSS 10.0 . All clinical factors were analyzed by Crosstabs or independent-samples t test. A mutivariative analysis of these significant factors was done by using the Binary Logistic Regression.Results Encephalopathy occurred in 21 cases within the first week after operation, including 19 cases of Child-pugh C and 2 cases of Child-pugh B. There was a higher occurrence in the patients with chronic severe hepatitis or undergoing re-transplantation ( P 0.05 ). In the encephalopathy group the incidence of renal failure after transplantation and infection pre- or postoperation was higher than in control group ( P
ABSTRACT
Hepatitis B recurrence is one of the most frequent complications that will probably result the treat failure of liver transplantation. As many as 80% of patients with HBV are reinfected by this virus after liver transplantation. This has been the most deadly case that threatens patient survival amongst all problems emerging from liver transplantation executed for Hepatitis B ralated hepatocirrhosis. In recent years a great deal of prophylaxis practices have been adopted, which has greatly reduced the possibility of Hepatitis B recurrence. The present paper reviews the causes and treatment of Hepatitis B recurrence after liver transplantation.
ABSTRACT
Objective To assess the use of medical services by patients with chronic hepatitis B, cirrhosis resulting from hepatitis, or hepatic carcinoma and the composition of the expenses incurred. Methods A survey was made on the use of outpatient and inpatient services as well as the details of medical expenses incurred by 1 395 self-funded patients and patients enjoying social medical insurance in Shanghai. And an analysis was made on the composition of the expenses and direct medical expenses per annum. Results There was no significant difference between the self-funded group and the insurance group in the use of outpatient and inpatient services; in terms of medical expenses, those incurred by the insurance group were 30% to 50% higher than those incurred by the self-funded group; an analysis on the composition of outpatient expenses showed that drug expenses accounted for over 80% and examination and test expenses accounted for over 15%; an analysis on the composition of inpatient expenses showed that drug expenses incurred by the two groups both accounted for 45% to 60% of the total expenses and examination and test expenses accounted for 15% to 25%. Conclusion Social medical insurance reduces the economic burden of individual patients but significantly raises treatment expenses. The key to containing the rise of medical expenses lies in controlling the conversion of hepatitis B to cirrhosis and the irrational growth of inpatient drug expenses and examination and test expenses.
