目的:构建伤口造口失禁专科护士能级评价方案,为该领域专科护士的能力评价提供参考。方法:运用文献分析、专家讨论及德尔菲法构建评价方案。于2020年9月随机选取全国213名伤口造口失禁专科护士为研究对象,收集其对评价方案各项指标的认可程度评分及本方案在专业领域中的适用性、可执行性与可推广性的综合评价数据。结果:两轮专家函询的积极系数均达到100%,专家权威系数为0.872,Kendall’s W值分别为0.252和0.331 (P均Objective: To construct a competency evaluation scheme for wound, ostomy, and continence specialist nurses, providing a reference for the capability assessment of nurses in this field. Methods: The evaluation scheme was constructed using literature analysis, expert discussions, and the Delphi method. In September 2020, 213 wound, ostomy, and continence specialist nurses were randomly selected nationwide as research subjects. Data were collected on their recognition degree scores for each indicator of the evaluation scheme, as well as comprehensive evaluation data on the scheme’s applicability, executability, and promotability in the professional field. Results: The positive coefficients of the two rounds of expert consultations were both 100%, the expert authority coefficient was 0.872, and the Kendall’s W values were 0.252 and 0.331 (both P < 0.001), indicating a high degree of consistency and reliability in expert opinions. The final competency evaluation scheme for wound, ostomy, and continence specialist nurses covers 5 dimensions, 3 competency levels, and 52 specific items. The survey found that the recognition degree scores for the scheme’s indicators were generally high, and the scheme received positive evaluations for its applicability, executability, and promotability in the professional field. Conclusion: The constructed competency evaluation scheme for wound, ostomy, and continence specialist nurses has good scientific and practical value, and can provide a scientific reference for the capability assessment of nurses in this field.
目的探讨miR-15b靶向LPAR3调控食管癌细胞增殖、迁移及侵袭的影响。方法取对数生长期的人食管癌Eca109细胞分为对照组、miR-15b mimic组、miR-NC组、miR-15b mimic+pcDNA3.1组、miR-15b mimic+pcDNA-LPAR3组;另设对数期生长的人食管上皮细胞HEEpiC为空白组。采用qRT-PCR检测各组细胞中miR-15b和LPAR3 mRNA的表达;应用MTT法、划痕实验和Transwell小室实验分别检测各组细胞的增殖、迁移和侵袭情况;Western blot检测Eca109细胞中LPAR3和增殖、迁移、侵袭相关蛋白(Cyclin D1、MMP-2、MMP-9)的表达。结果与空白组相比,对照组Eca109细胞中miR-15b水平明显降低(1.00±0 vs 0.42±0.03,t=33.486,P<0.01),LPAR3 mRNA水平显著升高(1.00±0 vs 2.33±0.15,t=15.358,P<0.01);与对照组相比,miR-15b mimic组细胞miR-15b水平显著升高(0.42±0.03 vs 4.61±0.38,t=19.039,P<0.01),LPAR3 mRNA(2.33±0.15 vs 1.29±0.13)和蛋白(1.12±0.13 vs 0.35±0.03)水平、细胞增殖率(100.00±0 vs 64.57±6.11)、划痕愈合率(63.45±7.20 vs 36.52±4.29)、Eca109细胞进入Transwell小室下层的数量(155.31±14.23 vs 101.33±11.45)、Cyclin D1(0.85±0.10 vs 0.38±0.05)、MMP-2(0.76±0.08 vs 0.33±0.04)、MMP-9(0.94±0.10 vs 0.41±0.05)蛋白表达均显著降低(t=9.075、9.996、10.044、5.565、5.119、7.281、8.327、8.211,P<0.01);使用pcDNA-LPAR3过表达LPAR3能明显逆转miR-15b mimic对细胞增殖、迁移和侵袭的抑制能力。结论食管癌中过表达miR-15b可能通过下调LPAR3表达,抑制食管癌细胞增殖、迁移和侵袭。
