[Application of "kindergarten effect" in radiotherapy for children with tumor aged 3-5 years].

Objectives: To study the clinical application effect of "kindergarten effect" in radiotherapy for children with tumor based on the psychology of preschool children aged 3-5 years.

Methods: A total of 30 children, aged 3-5 years, who were admitted to the Department of Radiotherapy, Tianjin Medical University Cancer Institute and Hospital, from January 2020 to August 2021 were enrolled in this prospective study. The children were randomly divided into a control group and a test group, with 15 children in each group.

Compassion fatigue among haemodialysis nurses in public and private hospitals in China.

Aim: This study was conducted to identify and compare the levels of compassion fatigue and job satisfaction among haemodialysis nurses in public and private hospitals in China and explore explanatory factors based on sociodemographic and occupational characteristics.

Methods: A descriptive study was conducted using a self-designed demographic questionnaire, the Professional Quality of Life Scale and the Minnesota Satisfaction Questionnaire, with responses from 283 haemodialysis nurses working at six public and private hospitals in China between June and November 2018.

Results: The compassion fatigue score of public hospital nurses was significantly higher than that of private hospital nurses.

Aluminum compounds containing eta1- and/or eta5-bidentate dianionic pyrrolyl-methylamide ligands.

A series of dialuminum compounds have been synthesized and their reactivity and application for lactide polymerization have been studied. The reaction of AlH3 x NMe3 with [C4H3NH(2-CH2NHtBu)] in diethyl ether generated a dimeric aluminum hydride compound, [[[C4H3N(2-CH2NtBu)]AlH]2] (1). The structure of 1 was confirmed by spectroscopy of a deuterated analogue of 1 with an Al--D function.
