目的:探究塑形垫结合热塑网膜体位固定方法在放疗过程中较单一热塑网膜或真空垫固定方法能否减少摆位误差。方法:分析2018年1月至2019年12月于湘雅常德医院接受放疗的头颈和胸腹肿瘤患者66例,其中头颈肿瘤患者27例、胸腹肿瘤患者39例。1... 目的:探究塑形垫结合热塑网膜体位固定方法在放疗过程中较单一热塑网膜或真空垫固定方法能否减少摆位误差。方法:分析2018年1月至2019年12月于湘雅常德医院接受放疗的头颈和胸腹肿瘤患者66例,其中头颈肿瘤患者27例、胸腹肿瘤患者39例。15例头颈肿瘤患者使用头颈肩热塑面罩固定(A组),12例使用塑形垫结合头颈肩热塑面罩固定(B组);19例胸腹肿瘤患者使用真空垫固定(A组),20例使用塑形垫结合热塑体膜固定(B组)。对所有患者实施锥形束CT扫描,统计配准后得到左右(left-right,LR)、头脚(superior-inferior,SI)和腹背(anterior-posterior,AP)方向及旋转角度摆位误差值,分析不同体位固定方式间的摆位误差大小。结果:对于头颈肿瘤患者,B组在LR、SI以及旋转角度误差分别为(0.06±0.06)cm、(0.08±0.07)cm、(0.12±0.17)°,小于A组的摆位误差(0.10±0.11)cm、(0.13±0.14)cm、(0.25±0.47)°,差异具有统计学意义(P<0.05),AP摆位误差差异无统计学意义(P>0.05);对于胸腹部肿瘤患者,B组在LR和旋转角度误差分别为(0.10±0.08)cm、(0.09±0.18)°,小于A组摆位误差(0.14±0.12)cm、(0.22±0.39)°,差异具有统计学意义(P<0.05),在SI和AP摆位误差差异无统计学意义(P>0.05)。结论:在头颈肿瘤和胸腹肿瘤患者放疗过程中使用塑形垫结合热塑网膜的体位固定方式相比于其他单一体位固定方式而言,能够提升患者体位的重复性、稳定性,减少摆位误差。 展开更多

OBJECTIVE:To investigate the relationship in malignant-neoplasm patients of hypercoagulability between syndromes differentiated with the theory of abnormal hilit in traditional Uyghur medicine(TUM).METHODS:A total of 248 patients with malignant tumors were enrolled.Based on the theory of TUM they were divided into two groups:abnormal Savda and abnormal Non-Savda(including abnormal Khan,abnormal Sepra and abnormal Belghem types);fifty healthy volunteers were selected as controls.Platelet(PLT),prothrombin time(PT),plasma fibrinogen(FIB),thrombin time(TT),activated partial thromboplastin time(aPTT)and D-Dimer(D-D)were measured in both groups.RESULTS:Compared with the control and abnor-mal Non-Savda groups,in the abnormal Savda group the PLT count increased(P<0.05),the PT was lengthened(P<0.01),and the FIB significantly increased(P<0.01).D-Ds in the three groups were significantly different(P<0.05).No significant difference was found inTT and aPTT values(P>0.05).CONCLUSION:Hypercoagulability existed in patients with malignant tumors in the different types of TUM syndromes,especially in the abnormal Savda group;this was characterized by increased blood viscosity,platelet aggregation and thrombosis.D-D appears to be a significant predictor for the therapeutic effect of TUM in relation to malignant tumor therapies. 展开更多
