目的:探讨老年白内障患者人格特点与术前视功能期望水平和术前焦虑的关系。方法:选取2023年1月至2023年9月在我院预期行白内障手术的98例老年白内障患者作为研究对象,将其作为观察组。另选同期在我院进行健康体检的50例老年人作为对照...目的:探讨老年白内障患者人格特点与术前视功能期望水平和术前焦虑的关系。方法:选取2023年1月至2023年9月在我院预期行白内障手术的98例老年白内障患者作为研究对象,将其作为观察组。另选同期在我院进行健康体检的50例老年人作为对照组。比较两组患者的大五因素人格量表(NEO Five-Factor Inventory,NEOFFI)评估结果。使用视觉功能问卷(Vision-Related Quality of Life and Visual Function,VFQ-25)、焦虑自评量表(Self-Rating Anxiety Scale,SAS)评估观察组患者的术前视功能期望水平、术前焦虑状况。分析老年白内障患者人格特点与术前视功能期望水平和术前焦虑的关系。结果:调查结果显示,观察组神经质、开放性、宜人性得分低于对照组(P<0.05)。相关性分析显示,老年白内障患者VFQ-25总分与SAS总分呈正相关(P<0.05),神经质维度、开放性维度、宜人性维度得分与SAS总分呈负相关(P<0.05)。多因素Logistic回归分析结果显示,神经质、开放性、宜人性、VFQ-25是老年白内障患者术前焦虑状况的独立影响因素。结论:老年白内障患者人格特征与健康老年人有明显差异,患者的人格特点、术前视功能期望水平与术前焦虑状况密切相关,可通过针对患者人格特点及术前视功能期望水平改善患者术前焦虑。展开更多

Hydroponic methods, K^＋-depletion methods, and patch-clamp, whole-cell recordings were conducted to study the accumulation of dry matter and potassium in different organs, and to measure potassium absorption and dynamic and in-ward potassium currents in potassium-enriched, fluecured tobacco genotypes. The average dry weights of leaves and whole plant of potassium-enriched, flue-cured tobacco genotype ND202 were 10.20, and 14.85 g, respectively, higher than JYH （8.50 and 13.11 g, respectively） and NC2326 （8.39 and 12.72 g, respectively）, when potassium concentration in the solution ranged from 0.1 to 50 mmol L^-1. Potassium accumulation in the leaves of ND202 was 18.6% higher than JYH and 34% higher than NC2326 when potassium concentration in the solution was superior to 0.5 mmol L^-1. The Vmax （the maximum velocity） of ND202 was 118.11 lamol FW g^-1 h^-1, obviously higher than that of JYH （58.87 μmol FW g^-1 h^-1） and NC2326 （64.40 μmol FW g^-1 h^-1）. In the in-ward potassium currents, the absolute value of current density （pA/pF） of ND202 was 60, higher than that of JYH （50） and NC2326 （40）. Potassium concentration in leaves, Vmax, and in-ward potassium currents, could be used to screen potassium-enriched, flue-cured tobacco genotypes.展开更多
