穿刺技术的改进和创新是穴位埋线疗法的第三次飞跃

穴位埋线是长效针灸,是在传统针具和针法基础上建立和发展起来的,是针灸技术的发展和延伸,穴位埋线的核心技术是穿刺技术,穴位埋线的三大要素中,针具、埋藏物、穿刺技巧之间是互相影响、互相促进的。针具的改进成功实现了穴位埋线疗法的第一次飞跃,埋藏物的改进成功实现了穴位埋线疗法的第二次飞跃,穿刺技术的改进和创新是穴位埋线疗法的第三次飞跃。     

生物信息学在肝细胞癌风险预测中的应用

生物信息学是一门交叉科学,通过综合运用数学、计算机科学和生物学的各种工具,来阐明和理解大量生物数据所包含的生物学意义。随着基因组学测序技术的不断发展,产生大量的生物学数据资源,从大数据中挖掘所蕴藏的生物学意义,已成为了当前亟待解决的主要任务之一。本文主要归纳总结基于特征基因的肝癌风险预测模型,为肝癌的早期检测、预后和治疗方案的优化提供新观点。     

In vivo epigenetic effects induced by engineered nanomaterials: A case study of copper oxide and laser printer-emitted engineered nanoparticles

Evidence continues to grow on potential environmental health hazards associated with engineered nanomaterials (ENMs). While the geno- and cytotoxic effects of ENMs have been investigated, their potential to target the epigenome remains largely unknown. The aim of this study is two-fold: 1) determining whether or not industry relevant ENMs can affect the epigenome in vivo and 2) validating a recently developed in vitro epigenetic screening platform for inhaled ENMs. Laser printer-emitted engineered nanoparticles (PEPs) released from nano-enabled toners during consumer use and copper oxide (CuO) were chosen since these particles induced significant epigenetic changes in a recent in vitro companion study. In this study, the epigenetic alterations in lung tissue, alveolar macrophages and peripheral blood from intratracheally instilled mice were evaluated. The methylation of global DNA and transposable elements (TEs), the expression of the DNA methylation machinery and TEs, in addition to general toxicological effects in the lung were assessed. CuO exhibited higher cell-damaging potential to the lung, while PEPs showed a greater ability to target the epigenome. Alterations in the methylation status of global DNA and TEs, and expression of TEs and DNA machinery in mouse lung were observed after exposure to CuO and PEPs. Additionally, epigenetic changes were detected in the peripheral blood after PEPs exposure. Altogether, CuO and PEPs can induce epigenetic alterations in a mouse experimental model, which in turn confirms that the recently developed in vitro epigenetic platform using macrophage and epithelial cell lines can be successfully utilized in the epigenetic screening of ENMs.     

督脉灸联合香砂养胃丸治疗脾虚泄泻的临床观察

目的观察督脉灸联合香砂养胃丸治疗脾虚泄泻的临床疗效。方法将2018年3月—2019年3月在东营市垦利县人民医院确诊为脾虚泄泻的90例患者,按照随机数字表法分为对照组和观察组各45例。对照组采用香砂养胃丸治疗,观察组采用香砂养胃丸联合督脉灸治疗。两组治疗1个疗程后观察并比较疗效以及治疗前后各项中医证候积分变化情况。结果治疗后观察组总有效率为88.89%,高于对照组的57.87%,观察组各项中医证候积分均降低且低于对照组,两组各项指标差异均具有统计学意义(P<0.05)。结论督脉灸联合香砂养胃丸治疗脾虚泄泻疗效显著,能够有效改善患者临床症状。     

8种寄生虫病例分析

本文报道并分析8例寄生虫病例,其中包括脑裂头蚴病、眼部裂头蚴病、肺吸虫幼虫移行症、肺吸虫病、钩虫病、肝吸虫病、包虫病和广州管圆线虫病各1例。8例寄生虫病均有不同程度的误诊,其中6例在寄生虫抗体筛查检测阳性后得以确诊。因此,寄生虫病应引起临床医生的重视,抗体筛查有助于发现寄生虫病例。
