Since the Third Plenary Session of the 11 thCentral Committee of the Communist Party of China( CPC),with the promotion and development of traditional Chinese medicine(TCM),the pace of TCM nursing work has been accelerated in nationwide,and a group of integrated Chinese and western medicine nurses have been cultivated preliminarily. However,professional nurses of integrated Chinese and western medicine are still deficient extremely. The target of talent cultivation,based on the theory of "focusing on humanism,expanding diathesis,and enhancing practice to highlight the accommodation and integration of nurses of integrated traditional Chinese and western medicine",is to cultivate competent,practical and interdisciplinary senior nursing talents with strong professional basis,skilled operations,rich humanistic literacy,and sharp innovative spirit who not only master modern nursing knowledge and skills,but also can perform comprehensive nursing under the guidance of TCM theory of holistic concept and syndrome differentiation and nursing. This study,through investigating and analyzing the settings of3-year nursing professional courses in about 20 senior medical colleges,including senior nursing education of TCM,reformed the development of professional nursing courses of integrated Chinese and western medicine and the establishment of educational materials according to the course settings and educational work modes,so as to analyze the current status of nursing education of integrated Chinese and western medicine,determine course targets,and establish course system and educational work modes. 展开更多

This study was designed to determine the total phenolic content of 50 herbs and to examine their antioxidant potential. In the sample preparation, 60% ethanol was chosen as the extraction solvent for the subsequent experiments. Folin-Cicolteau phenol reagent and a colorimetric method were used to determine the total phenolic content of the selected herbs. The result showed that total phenolic content of those herbs ranged from 2 to 185 mg/g. In antioxidant assay, the ferric reducing/antioxidant power (FRAP) values ranged from 2 to 134 mg GAE/g;the IC50 values of DPPH?·, ·OH and ?scavenging were in the range of 0.06 - 5.50 mg/mL, 0.017 - 0.636 mg/mL and 0.050 - 0.681 mg/mL respectively. Flos caryophylli was the exceptant in the ?scavenging assay because there was no linear relation between the concentration and the scavenging percentage. Compared to gallic acid, ascorbic acid and butylated hydroxytoluene (BHT) in antioxidant assay as positive control, the most potential antioxidant herbs were Cacumen platycladi, Radix et Rhizoma rhei, Rhizoma rhodiolae crenulatae, and Rhizoma sanguisorbae with considerable content of phenolics. Especially, a positive and significant correlation was found between the total phenolic content and FRAP value or DPPH· scavenging percentage. 展开更多

In recent years,the price of traditional Chinese medicinal materials soars continuously,and the resulting price risk increasingly looms large,which has critically affected midstream and downstream industries and peoples' demand for drug,and imperiled healthy and orderly development of traditional Chinese medicinal industries.Based on the status quo of continuous skyrocketing price of traditional Chinese medicinal materials at present,we winkle out the root cause of soaring price as follows:the supply and demand lose balance;the production costs hike up;there are other factors responsible for soaring price.This paper further analyses the impact of sharp increase in price of traditional Chinese medicinal materials on all links of industry chain as follows:the medicinal herb growers never benefit from soaring price;the counterfeiters and forgers in midstream industry increase;the gross profit rate of Chinese medicine enterprises declines.In accordance with the risk arising from abnormal fluctuation in price of traditional Chinese medicinal materials,corresponding precautionary measures are put forward as follows:promote the quality of traditional Chinese medicinal materials through management of value chain;curtail the production and management cost of traditional Chinese medicinal materials through management of organization chain;stabilize price of traditional Chinese medicinal materials through management of information chain;reduce transaction cost of traditional Chinese medicinal materials through management of logistics chain. 展开更多

At present,there are two modes in the compilation of textbooks of traditional Chinese medicine,one is stuck in one's own way and the other is to copy Western medicine completely.The reason is that the textbooks of traditional Chinese medicine colleges and universities are reduced into a hodger with no purpose,or the other is to cater to Western medicine system and give up the academic system of traditional Chinese medicine and lose the essence of traditional Chinese medicine.Through the"diagnosis and treatment strategy"and"knowledge link"of the new Chinese medicine textbooks,the author tries to make a breakthrough in the compilation,and puts forward the compilation ideas of rectifying the position of Chinese medicine textbooks,starting from the learning thinking of Western medicine students,and reflecting the characteristics of Chinese medicine and modern research results. 展开更多

Geochemical differentiation of soils has a series of consequences on plant and places pressure on the ecological environment.The quantitative evaluation of element migration in the Earth’s critical zone is a challenging task.In this study,two demonstration study areas of Scutellaria baicalensis Georgi were selected,and multiple chemical weathering indexes,chemical loss fraction,mass migration coefficients and biological enrichment coefficient method were used to assess the ecological and geochemical suitability.The results show that for the element of Fe,Zn,Se,Cu,Co,Ni,Mo and Ge,the degree of weathering and soil maturation,were greater in the rhyolitic tuff area than in the Plagioclase gneiss area.In both research sites,the heavy metal level of samples in Scutellaria baicalensis Georgi did not exceed the standard limits.The plagioclase gneiss region’s surface soil environment was more alkaline,and the content of soil organic matter was lower,resulting in a higher bioenrichment intensity of Ge,Co,Cu,and Se elements in Scutellaria baicalensis Georgi than in the rhyolite-tuff area.The elements of Cd,Nb,Mo,Pb and As are considerably enriched in the soil of the plagioclase gneiss area but lost by leaching in the soil of the rhyolite tuff area,which is connected to the interplay of elemental abundance and human impact in the parent materials.This study provides a good example of how to assess growth suitability of Chinese medicinal materials in the Earth’s critical zone. 展开更多

Pharmacodynamics material basis and effective mechanisms are the two main issues to decipher the mechnisms of action of Traditional Chinese medicines(TCMs)for the treatment of diseases.TCMs,in“multi-component,multi-target,multi-pathway”paradigm,show satisfactory clinical results in complex diseases.New ideas and methods are urgently needed to explain the complex interactions between TCMs and diseases.Network pharmacology(NP)provides a novel paradigm to uncover and visualize the underlying interaction networks of TCMs against multifactorial diseases.The development and application of NP has promoted the safety,efficacy,and mechanism investigations of TCMs,which then reinforces the credibility and popularity of TCMs.The current organcentricity of medicine and the“one disease-one target-one drug”dogma obstruct the understanding of complex diseases and the development of effective drugs.Therefore,more attentions should be paid to shift from“phenotype and symptom”to“endotype and cause”in understanding and redefining current diseases.In the past two decades,with the advent of advanced and intelligent technologies(such as metabolomics,proteomics,transcriptomics,single-cell omics,and artificial intelligence),NP has been improved and deeply implemented,and presented its great value and potential as the next drug-discovery paradigm.NP is developed to cure causal mechanisms instead of treating symptoms.This review briefly summarizes the recent research progress on NP application in TCMs for efficacy research,mechanism elucidation,target prediction,safety evaluation,drug repurposing,and drug design. 展开更多
