The quality of clinical practice teaching is an important factor affecting the quality of intensive care unit (ICU) specialist nurse training. We investigated the current situation of ICU specialist nurse training and teaching quality evaluation in China and around the world. There are several aspects that can be improved in the evaluation of the quality of clinical practice teaching for ICU specialist nurses in China. Result-oriented summative evaluation is mainly used in China, and there are few studies on the quality evaluation of clinical practice teaching process. Effective feedback mechanism has not been established for teaching quality evaluation. There is a lack of systematic theoretical guidance and few studies have been conducted on the formation of the quality of clinical practice teaching and the affecting factors. Therefore, there is an urgent need to construct a set of scientific and practical clinical practice teaching quality evaluation system for ICU specialist nurses under the guidance of systematic theory and in line with China's national conditions. We should formulate reasonable and uniform quality evaluation standards for clinical practice teaching, strengthen the quality evaluation of the training process on the basis of result-oriented quality evaluation. Moreover, the needs of all parties in the evaluation system should be comprehensively evaluated to improve the quality of clinical practice teaching.

The thyroid gland is an endocrine organ sensitive to ionizing radiation. Long term exposure to low dose radiation (LDR) among radiation workers in work may lead to thyroid dysfunction or the formation of thyroid nodules. The influencing factors of these outcomes are various and multifaceted, including but not limited to environmental factors (iodine intake levels), occupational factors (length of service, personal dose), and individual factors (gender, age, smoking, alcohol consumption, obesity, blood pressure, blood glucose). Currently, there is no consensus on the specific trends of thyroid nodule development and thyroid function indicators in radiation workers caused by long-term LDR exposure. Therefore, molecular epidemiological investigations should be conducted to explore its pathogenesis in the future, and long-term epidemiological investigations with multiple centers and large samples can be conducted to further verify existing findings. Furthermore, strengthening occupational health training of radiation workers and standardizing personal dose measurement are beneficial for comprehensive prevention of thyroid diseases, and ensuring occupational health of radiation workers.

Objective To observe changes in genetic material in the peripheral blood of pediatric patients with vascular malformations after interventional procedures. Methods A total of 108 children with vascular malformations who underwent interventional procedures at Shandong University Affiliated Children’s Hospital between February 2021 and January 2024 were selected as the research subjects. Clinical data and peripheral venous blood samples before and after the interventional procedures were collected from the children. Two biological indicators, γ-H2AX and peripheral blood lymphocyte chromosomal aberration (CA), were used to determine the levels of genetic material damage in children with vascular malformations before and after interventional procedures. Results The median age of the children was 7 years and the median body weight was 27 kg. The median dose-area product (DAP) was 24.20 Gy·cm2 and the median DAP/kg was 1.04 Gy·cm2/kg. The incidence rates of both γ-H2AX foci and CA in children with vascular malformations significantly increased after the interventional procedures (Z = 5.924, P < 0.001; Z = 8.515, P < 0.001). The incidence of postoperative CA in 7 children were significantly higher than that in others, approaching or exceeding 4%. The incidence rates of postoperative γ-H2AX foci and CA in children with DAP/kg ≥ 1 Gy·cm2/kg were significantly higher than those in children with DAP/kg < 1 Gy·cm2/kg (U = 7.586, P = 0.031; U = 6.835, P = 0.009). No significant differences were observed in the incidence rates of postoperative γ-H2AX foci and CA among subgroups based on age, body weight, or surgical site. A positive correlation was observed between the difference in the incidence rates of γ-H2AX foci before and after the procedure and DAP/kg (R = 0.493, P = 0.027). Conclusion Ionizing radiation exposure during interventional procedures can increase peripheral blood genetic material damage levels in children with vascular malformations, and the damage levels show a correlation with the radiation dose, with some children being abnormally sensitive. Further research is needed to explore the influencing factors for genetic material damage in children with vascular malformations after interventional procedures, which is of great significance for reducing long-term cancer risks and achieving personalized treatment strategies.
