OBJECTIVE:To discuss the protection effects of different dosage of reduced glutathione on liver function in acute myeloid leukemia(AML) patients undergoing chemotherapy.METHODS:In prospective study,72 AML patients were divided into group A and group B according to the dosage of reduced glutathione.Reduced glutathione were given to group A(1.2 g?d-1) and group B(2.4 g?d-1) 2 days before chemotherapy.Liver functions of patients were rechecked 1 week after chemotherapy.Another 2 weeks of treatment was given to patients with liver function disorder.RESULTS:1 week or 2 weeks after chemotherapy the incidence of liver function impairment in group B was decreased significantly,compared with group A(P

Purpose To investigate CT and MRI manifestations of renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusions (abbreviation as Xp11.2 translocation renal cell carcinoma).Materials and Methods Eighteen cases of Xp11.2 translocation renal cell carcinoma confirmed by pathology were retrospectively analyzed.Ten patients underwent CT scans,2 of them had unenhanced CT and 8 of them had pre-and post-contrast CT scan.Fourteen cases underwent plain and multi-phase contrast MRI scan,including 2 cases with unenhanced CT and 4 cases with pre-and post-contrast CT scan.The location,size,shape,density/signal,blood supply and the enhancement of the Xpl 1.2 translocation renal cell carcinoma were analyzed.Results All of the 18 tumors located in the corticomedullary with 17 solid lesions and 1 cystic lesion.The mean maximum diameter of the tumor was (4.6±2.0) cm.Thirteen lesions were circular or oval and 5 were irregularly or lobulated lesions.Ten lesions showed slightly high or high density on unenhanced CT,and the average CT value was (50.6± 11.5) HU,in which 4 lesions showed calcification.Among 8 cases of enhanced CT,1 lesion showed abundant blood supply,while 7 lesions showed lack of blood supply.Fourteen cases of MRI scan exhibited various imaging features with short T1 and T2 signal,and the persistent enhancement in the medullary phase.The MRI findings were further divided into 3 types according to the signal intensity and blood supply except 1 cystic lesion:① 5 lesions predominantly with short T1 and T2 signal were lack of blood supply;② 4 lesions predominantly with slightly longer T1 and T2 signal were abundant blood supply;③ 4 lesions predominantly with equal T1 and T2 signal were relatively lack of blood supply.Conclusion The CT and MRI features of Xpl 1.2 translocation renal cell carcinoma had certain manifestations:slightly high or high density nodule or mass located in corticomedullary on pre-contrast CT scan,various signal intensity with short T1 and T2 signal on MRI,and the persistent enhancement in the medullary phase.These image features combined with clinical data are helpful for diagnosis.

A safe and effective anesthesia technique is necessary in ensuring a successful surgical operation in rabbit experiments.A variety of anesthesiamethod have been reported, yet, no one matured and widely accepted anesthesiamethod is available so far.This article aims to provide an information basis for further research on general anesthesia in rabbits by reviewing the literature on single and combined anesthesia techniques in rabbits reported in the last decade.
