Background Apurinic apyrimidinic endonuclease/redox effector factor 1 (APE1/Ref-1) is an important enzyme in the repair of reactive oxygen species-induced DNA damage,and its expression/activation can be induced by reactive oxygen species.The aim of this research was to investigate the relationship between multiple-organ injuries and expression of Ref-1 in the early period after liver transplantation.Methods One hundred and fifty adult male Wistar rats were divided randomly into three groups:liver transplantation,sham surgery,and untreated control.After liver transplantation,animals were sacrificed at different time points.Hepatic and renal functions were analyzed by serology.Histology,apoptotic levels,and Ref-1 expression were examined by immunohistochemistry in the liver,kidneys,intestines,and lungs.Results Serum levels of alanine aminotransferase and aspartate aminotransferase peaked 6 hours after liver transplantation and decreased appreciably after 12 hours in the transplantation group,suggesting that the degree of liver injury in the early period after transplantation peaked at 6 hours and then decreased.Pathological analyses showed that hepatic tissues were more severely injured in the transplantation group than in the sham and untreated groups.A considerable number of infiltrating inflammatory cells was observed around the portal vein in the transplantation group.Injuries to the kidneys,intestines,and lungs were milder after liver transplantation.Apoptotic levels increased after liver transplantation in all four organs examined.Ref-1 expression was higher in the transplantation group in the early period after liver transplantation than in the sham surgery and untreated control groups.Conclusion Ref-1 expression induced by ischemia-reperfusion injury may have a critical role in repairing multiple-organ injuries after liver transplantation.

5.Research progress--the role of astrocyte in neuronal functions.
Journal of Zhejiang University. Medical sciences 2008;37(5):531-536
Astrocytes can regulate synaptic transmission by releasing gliotransmitter, and also can promote synaptogenesis and neurogenesis by releasing estrogen, thrombospondins, IL-1beta and IL-6. Astrocytes may play critical roles in neural nutrition and neuroprotection, so that it might be a new target for treatment of certain central nervous system diseases.

Complete healing of the intestinal mucosa is the most ideal goal in the treatment of inflammatory bowel disease (IBD). The intestinal mucosa healing not only significantly alters the course of the disease and relieves clinical symptoms, but also markedly reduces the occurrence of complications and prevents recurrence of IBD. As chronic inflammation associated with peptic ulcer damage is the main pathological feature of IBD, clinical treatment is mainly based on anti-inflammatory therapy, but such therapy cannot promote the healing of the intestinal mucosa of patients. Therefore, how to achieve long-term remission of IBD is still an urgent challenge. In the process of intestinal mucosal repair, the polarization of macrophages maintains the homeostasis of the intestinal microenvironment, which is a representative process that promotes mucosal inflammatory-repair. It is a key part of initiating tissue regeneration that should not be underestimated. In this paper, we reviewed the literature of the past decade, focusing on the promotion of intestinal mucosal healing in IBD. The discussion will highlight the importance and feasibility of regulating macrophages to promote intestinal mucosal repair. Following this thought, we discuss the shortcomings of current clinical treatments and summarize the relevant drugs which have potential to promote intestinal mucosal repair. The aim is to provide effective potential drugs and therapeutic targets for the treatment of IBD.

OBJECTIVETo evaluate the impact of lesion size on the detection rate of non-palpable breast malignant lesions and determine whether lesion size should prompt biopsy of non-palpable breast lesions.
METHODSThe study included 816 ultrasonographically detected non-palpable breast lesions. We divided the lesions into five groups based on their largest diameters: ≤0.5cm, 0.6-1.0cm, 1.1-1.5cm, 1.6-2.0 cm, and >2.0 cm. The detection rate of malignancies of different sizes were compared among these lesions, Breast Imaging Reporting and Data System (BI-RADS) category 2-3 lesions, and BI-RADS grades 4-5 lesions. The feasibility of using lesion size as biopsy indicator for BI-RADS category 2-3 non-palpable breast lesion was analyzed using ROC curve.
RESULTSOf these 816 lesions, 100 (12.3%) were found to be malignant lesions. The detection rate of malignancy significantly increased along with the increase of lesion size (P<0.05). When the BI-RADS category was not considered, the frequency of malignancy in the >2.0 cm group was significantly higher than in other groups (P<0.05) The frequencies of malignancy in the 0.6-1.0 cm group, 1.1-1.5 cm group, and 1.6-2.0 cm group were higher than that in ≤0.5 cm group, but the difference was not significant (P>0.05) For BI RADS category 4 and 5 lesions, the frequency of malignancy in >2.0 cm group was higher than in other groups, but significant difference was only seen between >2.0 cm group and ≤0.5 cm group (P<0.05).
CONCLUSIONSLesion size may influence the detection rate of malignancy of non palpable breast lesions, and can be used as biopsy indicator of non palpable breast lesions in BI-RADS 2,3 category When we use 1.25cm as threshold,the sensitivity and specificity may be satisfying.

OBJECTIVETo investigate the dynamic changes of neurofilament contents in rat's spinal cord induced by 2, 5-hexanedione (2, 5-HD), and explore the molecular mechanism of n-hexane neuropathy.
METHODSMale Wistar rats were administered at a dosage of 400 mg/kg/day 2, 5-HD for 2, 4 and 8 weeks respectively. HD-induced neurological defects were detected and quantified using gait score, and the relative lev-els of NF-H, NF-M, and NF-L in spinal cords of rats were determined by Western Blotting.
RESULTSExposure to 2, 5-HD produced progressive gait abnormalities, which suggested that the rat model of 2, 5-HD-induced neurotoxicity was established successfully. Western-Blotting results showed that NFs content in spinal cord demonstrated a progressive decline as the intoxication continued. In the supernatant fraction, compared to the controls, NF-H con-tent decreased by 15.7%, 57.0%, and 58.0% respectively after 2, 4, and 8-week treatment with 2, 5-HD (P < 0.01); accordingly, NF-M decreased by 36.0%, 61.3%, and 65.2% respectively (P < 0.01); NF-L decreased by 20.8%, 43.9%, and 44.3% respectively (P < 0.01). In the pellet fraction, the contents of NF-H in groups of 4 and 8 weeks' exposure to HD decreased by 35.6% and 43.2%, respectively (P < 0.01), and those of NF-L decreased by 26.4% and 42.1%, respectively (P < 0.01) when compared to the control. Further-more, NF-M contents in groups of 2, 4 and 8 weeks' exposure decreased by 23.3%, 33.9%, and 63.7% respectively (P < 0.01). The NFs level in spinal cords was highly correlated with gait abnormality of treated rats as the intoxication went on. Multiple correlation coefficients of NF-H, NF-M, and NF-L content with gait score of HD-treated rat were 0.8912, 0.9282 and 0.8981 (P < 0.01) respectively.
CONCLUSIONThe declines of NFs are high-ly related to neurobehavioral abnormality of 2, 5-HD-treated animals, and involved in the development of n-hexane neuropathy.
