巢蛋白在成年大鼠室周器官细胞的表达

目的:观察巢蛋白在成年大鼠室周器官细胞的表达,并根据巢蛋白阳性表达细胞的位置、大小及形态特点进行分类.方法:成年SD雄性大鼠,经心灌注后,用免疫组织化学检测巢蛋白在室周器官细胞的表达.结果:在正中隆起(64.32％±8.55％)、穹隆下器(15.76％±2.16％)、连合下器(40.15％±6.16％)和最后区(28.85％±4.53％)都可见大量的巢蛋白阳性表达细胞.根据细胞所在位置、大小和形态将其分为5类.Ⅰ类是室管膜细胞,部分室管膜细胞有长10～180 μm的胞突;Ⅱ类细胞较小,细胞及细胞核呈圆形或卵圆形,有1～2个纤细长达20～30 μm的胞突;Ⅲ类细胞胞体较Ⅱ类大,细胞及细胞核不规则,胞质浅染,无胞突;Ⅳ类细胞及细胞核呈圆形或卵圆形,大部分细胞无胞突,部分细胞有长4～15 μm的胞突;Ⅴ类细胞胞体较大,细胞及细胞核呈圆形或卵圆形,有1～3个粗长的突起,并可见2～3级分支,胞突长50～100μm.结论:成年大鼠室周器官有大量巢蛋白阳性表达细胞,有的是具有增殖和分化潜能的神经干细胞/祖细胞,有的是巢蛋白阳性表达的神经元.

The good,the bad,and the contingency: How patients’ treatment verification behaviors are linked to doctors’ reactions

ObjectiveThis article introducesTreatment Verification Behavior (TVB) to conceptualize patient proactivity. The article also aims to examine doctors’ responses to patients’ TVBs.MethodsA doctor-patient paired, two-wave data set was collected from eight hospitals in North China. We collected data from 304 doctor-patient dyads with each doctor rating, on average, three inpatients.ResultsThe results show that when patients consulted their doctors about information regarding a diagnosis or treatment (i.e.,consulting TVB), it improved doctors’ perception of the patients’ ability, which further increased doctors’ work engagement. Alternatively, when patients challenged doctors about information regarding a diagnosis or treatment (i.e., challenging TVB), it induced doctors’ perception of threat but without significantly decreasing doctors’ work engagement. In addition, when doctors felt respected by patients, this feeling moderated the effects of patients’ TVBs on doctors’ reactions.ConclusionBoth the content (the “what”) and the manner (the “how”) of patients’ proactive communications with their doctors will influence doctors’ responses.Practice implicationsThese insights suggest that patient and doctor communication training should include components that address both the content and performance of communication.
