Safely Using TCM Herbs： Adverse Reactions and Precautions

Although most people believe that herbal remedies are relatively safe to use, some are toxic or possess adverse reactions, especially when used incorrectly.Commonly used TCM herbs with known adverse reactions, as well as the most toxic herbs in the Pharmacopoeia of People’s Republic of China are listed as follows:

Chan su (Venenum Bufonis,蟾酥)Its main active and toxic constituent is bufotoxin, which has a function similar to digitalis glycosides.Adverse reactions and toxicity: Chan su, althoughit is used in patent preparations, is traditionally known for its toxicity and is seldom used in decoctions. Toxicity is often due to over dosage of the patents, such as Liushenwan (六神丸) and Houzhengwan (喉症丸). After administration

Xing ren (Semen Armeniacae Amarum, 杏仁) and Tao ren (Semen Persicae,桃仁)Both are seeds of fruits in Rosaceae. Both contain oils, amygdalin and emullsin.Adverse reactions and toxicity: Amygdalin is the main toxic constituent, which can be decomposed to hydrocyanic acid. Toxicity is dose related; 55 - 60 pieces of Xing ren, containing approxi-

The Concept and Design of Safety Management Innovation in the Use of Medical Equipment:Design of Real-time Monitoring System for Temperature and Humidity of Infant Incubator Based on Internet of Things in China

Ensuring safety in the use of medical equipment is an important guarantee for clinical diagnosis and treatment.Because medical equipment is mostly electrical and electronic equipment,the suddenness of its failure is inevitable.Although some equipment has regular preventive maintenance and metrological calibration,it is patient-free static calibrated.In China,because of its large population,large patient base,and large use of medical equipment,nurses are too busy taking care of patients and cannot pay attention to the safety of the use of each device.Therefore,we propose using the Internet of Things and IT technology to carry out real-time monitoring and alarming of important parameters of some special,high-risk,and large-used medical equipment,so as to strengthen the safety management of equipment use.Through the management innovation,this article successfully implemented real-time monitoring of the temperature and humidity of the neonatal incubator;and greatly improved the safety in the use of such equipment.

A synthetical methodology for identifying pr ior ity pollutants in reclaimed water based on meta-analysis

Wastewater reclamation and reuse is an increasing global project,while the reclamation treatment on wastewater does not completely remove all pollutants in water.The residual pollutants in reclaimed water would cause potential risk on human health and ecosystem safety during the long-term use.It is impossible to analyze and control all pollutants one by one in practice,therefore,identification and control of priority pollutants will be efficient strategy to ensure the safe use of reclaimed water.An integrated three-step methodology for identifying priority pollutants in reclaimed water was proposed in this study.First,a comprehensive literature survey on the occurrence of pollutants in reclaimed water was conducted,and a dataset D PR for pollutants occurrence in reclaimed water was established,containing 1,113 pollutants.Second,611 chemicals that had been recommended as hazardous pollutants for various water bodies in previous literatures were summarized,and a dataset D HP for hazardous pollutants in water was obtained.Third,meta-analysis on these two datasets(D PR and D HP)was performed,a new dataset D HPR for hazardous pollutants in reclaimed water was established,including 265 candidates.Finally,59 substances out of dataset D HPR were identified as priority pollutants for reclaimed water based on their recommendation frequency.It is expected that this synthetical methodology will provide powerful support for scientific evaluating and managing water pollution and ensuring safe use of reclaimed water.
