目的探讨白蛋白-胆红素(albumin-bilirubin,AlBI)评分对急性失代偿性心力衰竭(ADHF)患者短期全因死亡的预测价值,联合急性失代偿性心力衰竭国家注册研究(ADHErE)模型能否提高其预测能力。方法连续入选2018年1月至2021年3月在南京鼓楼医院心内科住院的ADHF患者共821例。根据入院AlBI评分,采用三分位法进行分组:低AlBI组(lBI组(-2.41~-2.10,n=274),高AlBI组(≥-2.10,n=274)。比较各组基线临床特征及实验室检查,主要终点为短期(院内或出院后30天内)全因死亡。采用logistics回归分析短期全因死亡的独立危险因素,绘制受试者工作特征(rOC)曲线,计算各模型rOC曲线下面积(AUC),根据约登指数确定最佳临界值,并计算不同模型间净重新分类指数(NrI),采用z检验比较模型间AUC及NrI的差异。结果共有45例(5.48%)患者在院内及出院后30天内死亡。高AlBI组患者全因死亡率显著高于其他两组(plogistics回归分析显示,AlBI评分(Or=4.012,95%CI 1.598~10.073,p=0.003)、ADHErE模型(Or=2.471,95%CI 1.317~4.434,p=0.004)、B型利钠肽水平(Or=1.000,95%CI 1.000~1.001,p=0.002)是ADHF患者短期全因死亡的独立危险因素。AlBI评分预测短期死亡的最佳临界值为-2.024。AlBI联合ADHErE评分对ADHF患者短期全因死亡的预测能力优于单独评分(AlBI+ADHErE比ADHErE:AUC p=0.008;NrI=0.37,95%CI 0.14~0.56,plBI+ADHErE比AlBI:NrI=0.37,95%CI 0.14~0.56,plBI评分与ADHF患者短期全因死亡风险独立相关,且AlBI联合ADHErE模型的预测价值更高。

All existing proton exchange membrane （pEM） fuel cell gas flow fields have been designed on the basis of single-phase gas flow distribution. the presence of liquid water in the flow causes non-uniform gas distribution, leading to poor cell performance. this paper demonstrates that a gas flow restrictor/distributor, as is commonly used in two-phase flow to stabilize multiphase transport lines and multiphase reactors, can improve the gas flow distribution by significantly reducing gas real-distribution caused by either non-uniform water formation in parallel flow channels or flow instability associated with negative-slope pressure drop characteristic of two-phase horizontal flow systems.

Amniotic fluid analysis involving 119 tapings was performed in 95 high risk pregnancy patients from march 1980 to October 1981. this is, at present, the most accurate method for assessing fetal maturity. the accuracy of the l/S ratio, foam test and creatine value was 96.98%, 94.89% and 86.6%, respectively. the study shows that amniotic fluid analysis plays an essential role in the planned delivery of high risk pregnancies. Intra-amniotic administration of dexamethasone can promote fetal maturity and is also very important in the management of the condition.

the morphologic classification and clinical spectrum of 1 001 cases of primary glomerulonephritis (GN) in Jinling Hospital during 1980-1988 were analysed. It was found that the incidence of mesangial type lesion including mesangial proliferative GN, IgA nephropathy and IgM nephropathy ranks first (21.5%, 32.1% and 10.1% respectively), which is not only the commonest cause of patients clinically manifesting nephrotic syndrome and gross hematuria but also the predominant type of nephritis causing uremia and hypertension.

Felt base carbon/carbon composites fabricated by super-high pressure impregnation carbonization process (SpIC) were heat treated at high temperature 2773K. the oxidation properties of felt base carbon/carbon composites were investigated at different temperatures (773-1173K), and the microstructures of carbon/carbon composites were studied by SEM and X-ray diffraction. the experimental results showed that the inter-laminar distance of (002) plane (d002) deceased while the microcrystalline stack height (lc) increased. the oxidation rate of felt base carbon/carbon composites was invari-able at certain temperatures. the oxidation mechanism of carbon/carbon composites changed remarkably at the oxidation temperature 973K. At the initial oxidation stage of carbon/carbon composites, carbon matrix was oxidized much more rapidly than carbon felt.
