目的研究手术治疗后Pilon骨折的临床结局,进而分析其可能的影响因素。方法选取2012年1月~2015年1月于笔者医院手术治疗的后Pilon骨折患者38例为研究对象。记录患者出院时红细胞计数(RBC)、白细胞计数(WBC)、血清白蛋白(ALB)、空腹血糖(F...目的研究手术治疗后Pilon骨折的临床结局,进而分析其可能的影响因素。方法选取2012年1月~2015年1月于笔者医院手术治疗的后Pilon骨折患者38例为研究对象。记录患者出院时红细胞计数(RBC)、白细胞计数(WBC)、血清白蛋白(ALB)、空腹血糖(FPG)等临床资料。对所有患者进行为期2年的随访,根据患者末次随访时Burwell-Charnley影像学标准及AOFAS踝与后足功能评分标准对患者进行分组,两项评价指标均达到优良定义为预后良好组,其余纳入预后不良组。根据患者术后并发症情况绘制Kaplan-Meier生存曲线,对其临床结局进行分析,并应用单因素分析及多因素Cox回归确定其影响因素。结果患者2年内不良临床结局的发生率为30.56%,并发症主要为创伤性关节炎,内固定失效,疼痛难以忍受行内固定取出。单因素分析显示,年龄、WBC、ALB、FPG对后Pilon骨折术后临床结局有影响(P<0.05),多因素Cox回归显示,年龄(RR=1.402,P=0.030)、FPG(RR=3.159,P=0.046)对后Pilon骨折术后临床结局存在明显影响,FPG对患者临床结局影响较大且高于年龄(RR=3.159 vs RR=1.402)。结论手术治疗后Pilon骨折的临床结局尚可,年龄和FPG对手术治疗后Pilon骨折的临床结局存在明显影响,FPG有望作为后Pilon骨折患者不良预后的检测指标之一,具有潜在临床预测价值。展开更多
The mixed oxides, Nd2-xSrxCoO4±λ(0.4 ≤ x≤ 1.2), with K2NiF4 structure were synthesized by the polyglycol gel method.

The composition and structure of the catalysts were characterized by means of IR, TPD, TPR, chemical analysis and so on. The catalytic performance for NO reduction was investigated. The results show that the mixed oxides have K2NiF4 structure. Other phases are found when x = 1.2. The amount of Co^3+ and the lattice oxygen over Nd2-xSrxCoO4±λ increase with the increase of x. It is found that the catalytic activity for NO reduction is closely correlated with the concentration of oxygen vacancies and the amount of Co^3+ .展开更多
