警惕耐甲氧西林葡萄球菌在医院的流行

耐甲氧西林葡萄球菌(MRS)包括耐甲氧西林金黄色葡萄球菌(MRSA)和耐甲氧西林表皮葡萄球菌(MRSE)。MRS是70年代初期在美国许多医院内感染的重要原因，一旦侵入医院则很难将其清除。Boyce的调查显示，发生MRSA感染的104家医院中，仅13家显清除。据国外报道，     

山西省医疗照射频度水平

本文报道了山西省医疗照射频度水平.采用分层抽样方法对省内25个县(市)居民医疗照射颇度进行了调查,并获得了约2×10⁵人次的病人数据,从而估算出诊断X线检查,临床核医学、放射治疗的总孩度(人次/千人口)分别为145.8,0.28,0.27。本文还给出了医疗照射频度随年龄、性别、地区和医院类型而变化。     

脑红蛋白在内毒素脑损伤大鼠模型中的表达变化

Objective To investigate the expression of neuroglobin(Ngb) in frontal cortex, cere-brospinal fluid (CSF) and serum in rats with brain injury induced by LPS and to elucidate its significance. Methods Seventy adult Sprague-Dawley rats were randomly divided into LPS (n = 60, with injection of 0.1 mg/kg LPS into cistern) and control (C, n =10, with injection of equal volume of isotonic saline into cistern) groups, with 10 rats in each group. The plasma, CSF as well as frontal cortex from sacrificed rats were collected in LPS group at 3, 6, 12, 24, 48, 72 post injection hour (PIH), with 10 rats at each time point. The protein expression of Ngb was measured by enzyme-linked immunosorbent assay(ELISA) and Western blot. Expression of Ngb in frontal cortex was determined by SP. Water content of frontal cortex was assessed by drying method. The correlation among Ngb contents in serum, CSF, frontal cortex and water con-tent of frontal cortex was analyzed with multiple comparison. Results Ngb expression ( by ELISA) : Ngb expression of frontal cortex, CSF, and serum in LPS group was higher than that in C group at each time point, and it peaked at 48 PBH (35.4±3.9, 22.7±3.1, 14.4±2.8 ng/mL, respectively, P <0.01). Ngb ex-pression ( by Western blot) : Ngb protein with relative molecular mass of 17×103 was observed in each group. Ngb expression detected by Western blot was similar to that detected by ELISA. Brain water content was significantly greater in LPS group than that of C group at 6-72 PIH ( P<0.01) , and it peaked at 48 PBH ( 83.3±1.9) %. Ngb contents in serum, CSF, frontal cortex, and water content of frontal cortex were positively correlated with muhipie comparison (γ=0.631-0.719, P<0.01). Conclusions Up-regu-lation of Ngb expression in brain injury induced by LPS is correlated with duration after challenge of LPS.
