清肝解郁和健脾补肾法在治疗肝火上亢型慢性肾衰合并高血压中的应用

目的:观察清肝解郁和健脾补肾法治疗肝火上亢型慢性肾衰(CRF)合并高血压患者的临床效果。方法:选取2016年6月至2018年6月京东誉美医院收治的肝火上亢型CRF合并高血压患者90例作为研究对象,按照随机数字表法随机分为对照组和观察组,每组45例。对照组给予口服硝苯地平控释片治疗,观察组在对照组治疗基础上给予清肝解郁、健脾补肾汤治疗,每4周为1个疗程,均治疗3个疗程。比较治疗前后中医症状评分、收缩压(SBP)、舒张压(DBP)变化;比较2组临床疗效;比较治疗前后肾功能指标:尿素氮(BUN)、血肌酐(Scr)、24 h尿蛋白定量(24 hPRO);统计治疗期间2组不良反应发生情况。结果:治疗前观察组与对照组中医症状评分、SBP、DBP、BUN、Scr、24 hPRO比较,差异均无统计学意义(P>0.05),治疗后2组患者中医症状评分、SBP、DBP、BUN、Scr、24 hPRO均显著降低(P<0.05),观察组均低于对照组,差异有统计学意义(P<0.05);2组临床疗效比较,差异有统计学意义(P<0.05),且观察组总有效率显著高于对照组,差异有统计学意义(P<0.05);观察组和对照组不良反应发生率分别为2.22%和6.67%,2组比较差异无统计学意义(P>0.05)。结论:清肝解郁、健脾补肾法辅助治疗肝火上亢型CRF合并高血压疗效确切,可较好控制血压,并且可显著改善肾功能,减少不良反应发生情况。     

The Dangerous Middle: Situational Awareness and Worker Perception of Beetle Kill

ABSTRACT

Forest workers, including loggers, foresters, and wildland firefighters, are regularly exposed to some of the most fatal occupational environments in the United States. These hazardous work environments may become even more complex and dynamic when subject to bark beetle outbreaks that have resulted in significant tree mortality. The impacts of tree death from bark beetles are significant, with the cumulative 17-year (2000–2016) footprint for bark beetle caused tree mortality estimated at 54 million acres. However, how workers think about and act in these environments is understudied. This study, therefore, approaches the issue of beetle kill and forest worker safety by examining the perspectives or workers themselves. Its contribution is to leverage ethnographic research to provide insights that can generate new research questions, better inform outreach, and ultimately improve worker safety outcomes. The resulting insights show that beetle kill was understood by workers as a hazard that increased the complexity and dynamism of the work environment, making situational awareness both more necessary and more difficult to maintain. While much research about situational awareness focuses on hazardous situations, it is suggested that building adequate situational awareness should also include broader considerations of organizational communication, as well as training and experience considered over the course of entire careers.     

《素问玄机原病式》学术思想探讨

《素问玄机原病式》一书，发挥《内经》病机学说，弥补了原“病机十九条”过于简略之不足，创造性地继承和发展了《内经》理论，特别是首倡“六气皆从火化”之说；关于“相火”的论述，则为后世相火理论的形成奠定了基础；它还总结了温热病的治疗原则，对后世温病学派的形成产生了重要影响。     

李杲《脾胃论》热中证探析

金元四大家之一李杲创立脾胃学说，认为“百病皆由脾胃衰而生”，脾胃不足则内生火热之邪，即阴火，是由饮食不节，形体劳役，七情内伤所致，这种阴火内盛的病证称为“热中”。后世医家对于热中证及阴火的实质有诸多争议，影响对脾胃学说的进一步理解和运用。根据李杲医著及其他医家论述分析，热中证的实质是由于脾胃内伤，化生风、湿、热、燥邪气，致使经络营卫运行不利而产生；阴火的治疗侧重于培补中气，除热祛邪。     

壮医针挑并艾灸治疗糖尿病周围神经病变临床观察

目的：观察壮医针挑并艾灸对糖尿病周围神经病变200例的疗效。方法：取龙路、火路网络在体表的反应穴或皮下反应点，每次选2～3个穴位，持针尖快速刺入皮肤0．1～0．2cm，绞断表皮少许纤维，尽量不出血，每3天1次，配合艾灸，10次为1疗程。结果：显效102例，有效78例，无效20例。总有效率为90％。结论：壮医针挑并艾灸治疗糖尿病周围神经病变疗效仍显著。     

Lead poisoning in precious metals refinery assayers: A failure to notify workers at high risk

Lead poisoning in a precious metals refinery fire assayer and a routine OSHA inspection prompted an investigation of the index facility, a survey of the industry, and efforts to notify assayers of this previously unrecognized hazard. Air and blood samples were obtained at the index facility. Management personnel from all fire assay laboratories in Rhode Island and southern Massachusetts were interviewed. The industry's trade association, OSHA, NIOSH, trade unions, and the media were asked to assist in a nationwide notification effort. Assayers at the index facility had excessive exposures to lead due to an age-old, lead-based assaying method that remains the industry gold standard. Blood lead levels of the three assayers (mean 61.3 μ/dl, range 48–86 μg/dl) were considerably higher than those of 16 other refinery workers (mean 27.4 μg/dl, range 13–49 μg/dl). The industry survey revealed inadequate knowledge of both the lead hazard and the applicability of the OSHA lead standard. Notification efforts failed in large part due to economic obstacles. The notification of workers at high risk of lead exposure and the eradication of occupational lead poisoning will require greater attention to economic forces. © 1994 Wiley-Liss, Inc.
