This study outlines the essential nursing strategies employed in the care of 10 patients experiencing vascular vagal reflex, managed with artificial liver support systems. It highlights a holistic nursing approach tailored to the distinct clinical manifestations of these patients. Key interventions included early detection of psychological issues prior to initiating treatment, the implementation of comprehensive health education, meticulous monitoring of vital signs throughout the therapy, prompt emergency interventions when needed, adherence to prescribed medication protocols, and careful post-treatment observations including venous catheter management. Following rigorous treatment and dedicated nursing care, 7 patients demonstrated significant improvement and were subsequently discharged.

Bacterial family Christensenellaceae performed high heritability and associated with human health status. Numerous studies observed that the abundance of Christensenellaceae could be significantly reduced in patients with intestinal diseases or metabolic disorders， inferred that it may be treated as an effective biomarker. Christensenella minuta (C. minuta) was the first member of Christensenellaceae family isolated from human fecal samples. Accumulating evidences suggested that C. minuta may demonstrate a positive bio-therapeutic effects toward unhealthy status. Hence， this review aimed to systematically summarize the characterization of Christensenellaceae under specific health or diseases， and discover its promising application. Besides， the latest studies on the pharmacological research of C. minuta also summarized. Current important literatures grasped the potential health benefits of C. minuta in managing metabolic disorders， gut ecosystem， and inflammation. Whereas， several critical knowledge gaps about the safe and clinical application remain should be addressed in future verification. C. minuta is worthy to be elevated as the next prospective probiotic star in nutraceutical or medical field and should not be overlooked.

行政立法权作用于民事活动可以规避自治过度对公共性的破坏,但行政立法权可作用的民事活动范围在规范层面并不十分清晰,加之《民法典》第153条在司法适用中有被误用的趋势,实践中行政立法权对民事活动的介入呈现过度之势。行政立法权作用于民事活动必须秉持尊重自治原则,在立法层面,需诉诸法律保留范围的改造与强制性规定内容的重新解读;在司法层面,应借助“例外有效”条款的解释来降低行政立法权过度介入民事活动的风险,提高行政立法权作用于民事活动的效能。

保暖织物在人类生活中扮演着不可或缺的重要角色.传统保暖织物通常由天然纤维(棉、麻、蚕丝)或人造纤维(聚酯、尼龙、聚丙烯腈、聚氨酯)构成.随着时代发展,传统保暖织物的性能已经不能满足日益提高的特别是面对极端复杂环境的保暖需求.气凝胶纤维是一种具有三维多孔网络结构的纤维,具有极高的孔隙率、极大的比表面积和极低的密度,是一种理想的绝热纤维,具有用于高性能保暖织物的潜力.然而,气凝胶纤维通常强度低、韧性差,被加工应用的能力较差,限制了其应用于保暖衣物[1].在过去10年里,研究者基于各种材料,包括碳纳米管、凯夫拉、聚酰亚胺、纤维素和石墨烯等,通过溶胶凝胶转变和特定的干燥方法,并通过结构设计成功制备了具有一定力学柔韧性(可弯曲、打结)的气凝胶纤维[2].但是,上述方法获得的气凝胶纤维的力学性能仍然无法满足织造(编织和针织)的要求,更无法满足耐水洗、耐磨等实用性织物的要求.
