Recent advances in the detection of acute kidney injury(AKI) afford the possibility of early intervention. Proteomics and genomics have identified many markers of tubular cell injury, some of which are manifest in the urine. One trial has used novel injury biomarkers to recruit patients to an intervention prior to an elevation in plasma creatinine. This trial and other recent studies have shown that the use of biomarkers of injury will depend on the time the patient presents following insult to the kidney, the likely cause of that insult, and the pre-injury renal function of that patient. The definition of AKI is likely to change in the near future to include a measure of injury. We anticipate novel therapies becoming available following successful trials that utilize the methodology of early intervention following an elevated injury biomarker.

AIM： To examine the effect of acute infection caused by herpesvirus （pseudorabies virus, PRV） on pancreatic ductal secretion. METHODS： The virulent Ba-DupGreen （BDG） and non- virulent Ka-RREp01acgfp （KEG） genetically modified strains of PRV were used in this study and both of them contain the gene for green fluorescent protein （GFP）. Small intra/ interlobular ducts were infected with BDG virus （10^7 PFU/mL for 6 h） or with KEG virus （10^10 PFU/mL for 6 h）, while non-infected ducts were incubated only with the culture media. The ducts were then cultured for a further 18 h. The rate of HCO3 secretion [base efflux -λ（B）] was determined from the buffering capacity of the cells and the initial rate of intracellular acidification （1） after sudden blockage of basolateral base loaders with dihydro-4,4,- diisothiocyanatostilbene-2,2,-disulfonic acid （500 μmol/L） and amiloride （200 μmol/L）, and （2） after alkali loading the ducts by exposure to nH4Cl. All the experiments were performed in HCO3-buffered Ringer solution at 37 ℃ （n = 5 ducts for each experimental condition）. Viral structural proteins were visualized by immunohistochemistry. Virallyencoded GFP and immunofluorescence signals were recorded by a confocal laser scanning microscope.RESULTS： The BDG virus infected the majority of accessible cells of the duct as judged by the appearance of GFP and viral anUgens in the ductal cells. KEG virus caused a similarly high efficiency of infection. After blockage of basolateral base loaders, BDG infection significantly elevated -λB-） 24 h after the infection, compared to the non-infected group. However, KEG infection did not modify -λB-）. After alkali loading the ducts, -λB-） was significantly elevated in the BDG group compared to the control group 24 h after the infection. As we found with the inhibitor stop method, no change was observed in the group KEG compared to the non-infected group. COnCLUSIOn： Incubation with the BDG or KEG strains of PRV results in an effective i

目的对需要抗心绞痛治疗并且左心室功能代偿症状稳定的心绞痛患者建立预测全因死亡、心肌梗死和导致致残性卒中的复合危险评分。设计大型多中心临床试验数据的多变量Cox回归分析。背景西欧、以色列、加拿大、澳大利亚和新西兰的心脏专科门诊患者。入选者7311例具有全部需要资料的患者被入选。主要结局的测量指标平均随访4.9年时间内所有原因的死亡、心肌梗死或者致残性卒中。结果1063例患者发生任何原因死亡或者持久性心肌梗死或者致残性卒中。这些复合终点的5年危险性在危险性最低的十分位患者为4%,而在危险性最高的十分位患者为35%。危险评分结合16项临床常规变量的降序排序是:年龄、左心室射血分数、吸烟、白细胞计数、糖尿病、随机血糖浓度、肌酐浓度、既往卒中病史、1周至少1次心绞痛发作、冠状动脉造影发现(如果能够获得)、降脂治疗、QT间期、收缩期血压≥150mmHg、抗心绞痛药物数量、陈旧性心肌梗死以及性别。把这个模型分别应用于任何原因所致的死亡、心肌梗死和卒中进行预测评估,所得的结果相似。危险评分似乎不能预测事件性质(39%的死亡、46%心肌梗死以及15%致残性卒中)或者冠状动脉造影或血管重建率(占29%的患者)。结论该危险评分对客观地决定稳定性心绞痛患者进一步治疗措施以减少重要预后事件发生是有帮助的。该危险评分同样可以用于将来的计划性试验。
