A facile method for the preparation of sodium alginate（SA）/carboxyl-functionalized graphene（G-COOH）composite hydrogel was developed. Based on the coordination ability of lanthanide ions to the carboxyl groups, a series of hydrogel derived from different ratios of SA and G-COOH was fabricated by neodymium（Nd3＋） ions coordination. A relatively uniform layered structure was recorded by SEM at the interior of SA/G-COOH hydrogel. Several parameters such as water content, swelling ratio（SR）, tensile test and solvent resistance were also investigated. The SA/G-COOH composite hydrogel showed excellent mechanical strength, and the tensile strength of SA/G-COOH composite hydrogel reaches 53.72 MPa at high water content. due to the coordination ability of Nd3＋ ions, the hydrogel also exhibited an excellent solvent resistance and stability.

目的探讨血清可溶性髓样细胞触发受体-1(sTREM-1)、激活调节正常T细胞表达和分泌因子(RANTES)水平与病毒性心肌炎患者(VM)不良预后的关系。方法选取2019年8月至2022年8月北京市东城区第一人民医收治的200例VM患者作为研究对象,根据随访情况分为预后不良组86例,预后良好组114例。同时选取200例同期该院体检健康人员作为对照组。收集各组一般资料,并检测血清sTREM-1、RANTES、血清白细胞介素-18(IL-18)、血清高敏C反应蛋白(hs-CRP)、肌酸激酶同工酶(CK-MB)、肌酸激酶(CK)、心肌肌钙蛋白I(cTnI)水平。对VM患者预后随访12个月,比较预后良好组和预后不良组的一般资料及血清sTREM-1、RANTES水平。采用受试者工作特征(ROC)曲线分析血清sTREM-1、RANTES水平对VM患者发生不良预后的预测价值,Logistic回归分析影响VM患者发生不良预后的危险因素。结果 VM组sTREM-1、RANTES水平明显高于对照组(P<0.05),预后不良组CK-MB、cTnI、hs-CRP、CK、IL-18水平高于预后良好组(P<0.05)。ROC曲线结果显示,血清sTREM-1、RANTES的ROC曲线的下面积(AUC)分别为0.814、0.824,二者联合检测的AUC为0.905,高于sTREM-1、RANTES单独检测(Z=2.485、2.212,均P<0.05)。Logistic多因素回归分析显示,sTREM-1、RANTES水平是影响VM患者预后不良的危险因素(P<0.05)。结论血清sTREM-1、RANTES水平对VM患者的不良预后具有重要的预测价值。

为了量化研究积灰状态下回转式空气预热器(空预器)对运行条件的敏感性,构建基于局部热非平衡模型的三方程回转式空预器热力计算模型,探究了积灰分布与运行条件对空预器传热性能和硫酸氢铵(ABS)沉积的综合影响,对比分析了积灰热阻与热容对空预器的影响规律。计算结果表明:积灰热阻对传热性能的削弱效果远大于积灰热容对传热的强化效果;冷段积灰比例的增加使得ABS沉积区比例增大;当蓄热元件表面积灰厚度增加时,提高转速、增大流量或提升机组负荷对改善传热性能及减小ABS沉积区比例的效果尤为显著;改变流体温度对空预器性能的影响较小;当机组负荷由50%增加至100%时,ABS沉积区比例在清洁状态下的减小量为5%,在冷段积灰厚度为2 mm时提高至7%。研究结果可为针对性地调整空预器运行参数,从而优化传热效果及减轻积灰腐蚀提供参考。
