The mechanisms underlying Chinese medicines to treat inflammation in diabetic kidney disease

Many Chinese medicinal materials, vegetable oils and extracts, and even Chinese patent medicines are spicy, which influences the medication compliance of patients, especially children. Different from the sour, sweet, bitter, salty, and umami tastes, it is a painful sensation formed when the spicy substances stimulate the nerve endings. At the moment, there are a few studies on the spicy components and mechanism and masking technology for the spicy flavor of Chinese medicine in the pharmaceutical industry, and the findings in food science are usually taken as a reference, which fail to guide the masking of the spicy flavor in Chinese medicine preparations. According to literature research, the exterior-releasing medicine, dampness-resolving medicine, and interior-warming medicine are spicy, especially some vegetable oils and extracts. Taking Zingiberis Rhizoma and prescriptions containing this medicinal as an example, the spicy components in Chinese medicine and the structure-activity characteristics were analyzed to reveal the mechanism for the spicy flavor: spicy components activate the transient receptor potential vanilloid subfamily member 1(TRPV1). The advantages and disadvantages of separation, neutralization with sugar, and inclusion for the masking of the spicy flavor were summarized and the applicability in Chinese medicine was analyzed. Moreover, the future development direction was put forward. This study is expected to promote the development of spicy masking technology for Chinese medicine prescriptions for children.

Plant growth regulator is a kind of synthetic pesticide with similar physiological activity to plant hormones. It has been widely used in grain, vegetables, fruits, flowers and other crops, and become an important technical guarantee for high yield, stable yield, high quality and efficient production of crops. In recent years, plant growth regulator is widely used in Chinese herbal medicine production for regulating the growth and development and increasing production of traditional. However the crop is different from general Chinese medicinal materials, the use of plant growth regulator should not only consider the effect of Chinese herbal medicine production, and also pay special attention to the influence of Chinese traditional medicine efficacy and safety. This paper reviewed the application of plant growth regulator in the traditional Chinese medicine, the impact on the quality and safety of Chinese medicinal materials, as well as plant growth regulator of residue limits standards and testing technology, so as to the scientific use of plant growth regulator, to promote Chinese standardization planting, provide the scientific basis to protect the safety of herbal medicine. At present, the indiscriminate use and abuse of plant growth regulators such as Zhuanggenling and bulking element are common in the production of Chinese crude drugs, which has led to a significant decline in the quality of some Chinese crude drugs, and resulted in the dual residual harm to the Chinese crude drugs and the cultivation environment, causing serious safety risks to human health. In the future, it is necessary to strengthen the registration management, use norms and limit standards of plant growth regulators in traditional Chinese medicinal materials, and strengthen the supervision and regulations on the use of fertilizer instead of medicine to avoid pesticide registration and other disorders, so as to provide a basis for the quality and safety monitoring of traditional Chinese medicinal materials. Simultaneously, it is encouraged to reduction or non-application of plant growth regulators in the production of Chinese medicinal materials, especially for traditional Chinese medicine which contains a variety of active ingredients. Therefore, it is actively advocated to cultivate Chinese medicinal materials through organic or ecological method.

With the rapid development of comprehensive health industry, the demand for Chinese medicinal materials is increasing. There is also a growing demand for land for the cultivation of Chinese medicinal materials.Based on the analysis of the demand characteristics of planting habitats for Chinese medicinal herbs, this paper finds that compared with the cultivated environment, the wild environment is more conducive to the improvement of the quality and stress resistance of medicinal plants. The eco-planting for Chinese medicinal materials is the only way to achieve high quality, efficient and sustainable production of traditional Chinese medicine. Therefore, according to the habitat distribution characteristics of wild medicinal plants, combined with the current situation of land resource utilization in China and the increasing demand for land for Chinese herbal medicine cultivation, the land use strategy of Chinese herbal medicine ecological agriculture was proposed. ① To vigorously develop underwood planting and change the existing field cultivation mode. ② To make full use of mountainous areas and barren slopes to carry out wild planta tending or planting imitates wild condition. ③ According to the development law and biological characteristics of medicinal plants, the land resources should be developed and used rationally according to local conditions.This can not only meet the requirements of the specific growth environment of Chinese medicinal materials, realize the sustainable development of the Chinese medicinal materials industry, but also increase the economic income of people in mountainous areas, provide scientific and effective solutions for the land use of Chinese medicinal materials, and also have important significance for the protection of wild Chinese medicinal materials.

The present study analyzed the current Chinese medicinal health products and Chinese patent medicines effective in boosting memory,aiming at providing references for the formulation and development of memory-boosting health products. The information on memory-boosting health products published by the Department of Special Food Safety Supervision and Management,the State Administration for Market Regulation( SAMR) was collected and the Chinese patent medicines on DRUGDATAEXPY were searched. Microsoft Excel and the TCMISS were used to statistically analyze the characteristics of formulations. A total of 212 memory-boosting health products were obtained from SAMR,including 83 ones containing Chinese medicinal materials. Twelve Chinese herbal medicines showed a usage frequency ≥ 8,with 151 times in use. In DRUGDATAEXPY,258 similar Chinese patent medicines were collected.Twelve Chinese herbal medicines showed a usage frequency ≥ 58,with 907 times in use. Through unsupervised hierarchical entropybased clustering of the above-mentioned Chinese medicinal health products and Chinese patent medicines separately,5 and 12 new formulas were obtained. The selection of Chinese herbal medicines for the new formulas was consistent with the principles of traditional Chinese medicine( TCM) theories,i. e.,tonifying kidney and marrow,benefiting Qi,nourishing Yin,resolving phlegm,and eliminating stasis. According to TCM theories,syndrome differentiation of the users was conducted,and the formulas were designed following the correspondence of syndromes with formulas and Chinese herbal medicines. This study is expected to provide new ideas and methods for the development of Chinese medicinal health products and accurately guide practical applications to exert the advantages of TCM in health care based on syndrome differentiation and improve the effect of Chinese medicinal health products.

Economic botany collections: A source of material evidence for exploring historical changes in Chinese medicinal materials

This paper examines the supply and utilization of traditional Chinese medicine (TCM) in Hong Kong during the influenza epidemics of the 1950s and 1960s. Existing narratives of TCM in Hong Kong have predominantly framed with within the dichotomy of Western medicine “Xiyi” and Chinese medicine “Zhongyi,” portraying TCM as marginalized and nearly wiped out by colonial power. Departing from this binary opposition, this study views TCM as an autonomous space that had never been subjugated by the colonial power which opted for minimal interventionist approach toward TCM. By adopting diachronic and synchronic perspectives on Hong Kong's unique environment shaped by its colonial history and the geopolitics of the Cold War in East Asia, particularly its relationships with “China,” this research seeks to reassess the role and status of TCM in post-World War II Hong Kong.In Hong Kong, along with other countries in East Asia, traditional medicine has ceded its position as mainstream medicine to Western medicine. Faced with the crisis of “extinction,” Chinese medical professionals, including medical practitioners and merchant groups, persistently sought solidarity and “self-renewal.” In the 1950s and 1960s, the colonial authorities heavily relied on private entities, including charity hospitals and clinics; furthermore, there was a lack of provision of public healthcare and official prevention measures against the epidemic influenza. As such, it is not surprising that the Chinese utilized TCM, along with Western medicine, to contain the epidemics which brought about an explosive surge in the number of patients from novel influenza viruses. TCM was significantly consumed during these explosive outbreaks of influenza in 1957 and 1968.In making this argument, this paper firstly provides an overview of the associations of Chinese medical practitioners and merchants who were crucial to the development of TCM in Hong Kong. Secondly, it analyzes one level of active provision and consumption of Chinese medicine during the two flu epidemics, focusing on the medical practices of TCM practitioners in the 1957 epidemic. While recognizing the etiologic agent or agents of the disease as influenza viruses, the group of Chinese medical practitioners of the Chinese Medical Society in Hong Kong adopted the basic principles of traditional medicine regarding influenza, such as Shanghanlun and Wenbingxue, to distinguish the disease status among patients and prescribe medicine according to correct diagnoses, which were effective. Thirdly, this paper examines the level of folk culture among the people, who utilized famous prescriptions of Chinese herbal medicine and alimentotherapy, in addition to Chinese patent medicines imported from mainland China. In the context of regional commercial network, this section also demonstrates how Hong Kong served as a sole exporting port of medicinal materials (e.g., Chinese herbs) and Chinese patent medicines from the People’s Republic of China to capitalist markets, including Hong Kong, under the socialist planned or controlled economy in the 1950s and 1960s.It was not only the efficacy of TCM in restoring immunity and alleviating symptoms of the human body, but also the voluntary efforts of these Chinese medical practitioners who sought to defend national medicine “Guoyi,” positioning it as complementary and alternative medicine to scientific medicine. Additionally, merchants who imported and distributed Chinese medicinal materials and national “Guochan” Chinese patent medicine played a crucial role, as did the people who utilized Chinese medicine, all of which contributed to making TCM thrive in colonial Hong Kong.

The purposes of this study were (1) to understand student nurses' knowledge, attitude, and behavior toward Chinese medicine and (2) to explore the related factors. This study was based on a structured questionnaire survey. The subjects of the study were students from the nursing department of one technical university in southern Taiwan. The sampling methods of this study were stratified sampling and cluster sampling. After getting the agreement of the student nurses, the researcher gave out 518 questionnaires to do the test. There were 496 valid questionnaires and the retrieval ratio was 96%. The results were: (1) The highest mean score was for the basic concepts of Chinese medicine and the lowest mean score was for the basic concepts of Chinese herbal medicine. The average correctness rate of knowledge about Chinese medicine was 67.42%. (2) The student nurses had a positive attitude toward Chinese medicine. (3) As for the frequency of seeking Chinese medical treatment, most of the student nurses used common folk tonics of Chinese medicine to recuperate their health. As for the medical treatment of general diseases, muscular and skeletal diseases were the most. (4) The significant common related factors for student nurses' knowledge, attitude, and behavior toward Chinese medicine were " have ever studied the literature of Chinese medicine or Chinese medicine nursing" and " have sources of knowledge on Chinese medicine". The factors "have ever studied the credit points of Chinese medicine", and " all credit points of Chinese medicine that have ever studied" also significantly influenced student nurses' knowledge and attitude toward Chinese medicine. Additionally, there were significantly positive pairwise correlations between student nurses' knowledge, attitude, and behavior toward Chinese medicine. The results of this study suggest that nursing schools should arrange curricula in Chinese medicine as required credits in the education of student nurses and provide student nurses with information on Chinese medicine by various kinds of formal and informal methods to promote the Chinese medicine knowledge, attitude, and behavior of student nurses and to accelerate the personnel cultivation of Chinese medicine nursing in order to meet the needs of society.

The health food industry is an important support for the big health industry and the strategy of healthy China. The Chinese medicine prescription health food has exceeded 60% of the total declared health food. However,the main basis for its function evaluation,the Technical Specification for Inspection and Evaluation of Health Food,was abolished in 2018,and 27 of them were based on modern medical and nutritional theories. Quantitative efficacy evaluation methods in western pharmacology are short of function claims and function evaluation methods reflecting the characteristics of traditional Chinese medicine,which could affect the health food industry to a certain extent. Therefore,the establishment of the evaluation mechanism of Chinese medicine prescription health food which conforms to the positioning of health food and the theory of traditional Chinese medicine is helpful for the healthy development of health food industry. In this paper,this problem was explained from five aspects. First,how to differentiate the positioning of Chinese medicine prescription health food from ordinary food and medicine,and how to embody the characteristics of Chinese medicine. Secondly,the relationship between traditional Chinese medicine prescription health food and Chinese patent medicine. Thirdly,how to scientifically and reasonably determine the raw materials of traditional Chinese medicine prescription health food. Fourthly,how to explain the function claim of traditional Chinese medicine prescription health food,and how to evaluate its function scientifically and reasonably. Fifthly,the functional evaluation of Chinese herbal medicine prescription health food is connected with other national scientific and technological strategies. In this paper,a preliminary analysis of the Chinese medicine prescription health food was conducted from the above five aspects,and some personal views and suggestions were put forward,hoping to provide reference for the competent authorities and researchers.

China medicine has a long history, Chinese traditional medicine (TCM) is an important component of Chinese medicine, but also reflect the basic means of TCM curative effects. Compounds of TCM are mixture of drugs according to certain compatibility rules, complex composition. In clinical application certain herbs are selected following the compatibility law as a means, to achieve treatment for different diseases. Therefore, the effective components of Chinese medicine, the effective components of single drug or effective ingredients of the traditional Chinese medicine prescription are not compatibility, studying the superposition, inhibition the interaction between the components is essential. In recent years, the application of modern information technology has been developed, and applied in a lot of the research of TCM. Especially the technology of data mining, excavation of the Chinese native medicine compound prescription has become an important means of modernization of traditional Chinese medicine. Data mining technology is a set of scientific method to solve the problem of a large number of data from the application of various fields and put forward, mainly in order to discover the hidden knowledge and rules in the data, provide data and theoretical support for the decision scheme of human. Many TCM databases have been established. So we attempt to study the application of data mining technology in traditional Chinese medicine effective constituents in compound prescription and regulation, try to analyze and explore the effectiveness of compositions of TCM by computer. This paper uses the data mining technology as a means, analysis of composition rules and active components on the spleen and stomach and heat compound prescriptions, which mainly includes the following work: Data mining is the core algorithm. Some set of frequent items mining method based on APriori method, candidate set generation needs to constantly scanning the database, time consumption. FP-growth is a kind of mining method without generating candidate itemsets important frequent item sets.In this paper, based on the improved algorithm, the new algorithm uses the modified FP-tree and the head table structure, produce only FP-tree once, and produced only head table structure at each recursion. The new algorithm can obtain the same as the original algorithm of frequent item sets mining results, but the speed of at least twice faster than the FP-growth. Screening of the data, the other agent data preprocessing, create the database, use the improved algorithm, the initial establishment of effective component and computer composing principle of traditional Chinese medicine compound simulation system, the system through the data mining techniques: frequent item sets, association rules, clustering analysis algorithm, carries on the analysis to the frequency of drug ingredients, compound symptom frequency, medicine sickness connection, pharmaceutical composition clustering, find out the related effective ingredients and disorder of spleen and stomach and Qingre prescription among.

Although several traditional Chinese medicine (TCM)-related databases have emerged, they focus on researching single medicinal materials, which is far from sufficient for clinical research and application. In comparison, compound prescriptions are more informative and meaningful in TCM, for they embody the information on the compatibility of TCM besides the relatively isolated information about single medicinal materials. The compatibility information is essential in TCM because it conveys not only what components are involved to treat special diseases but also how to combine these single medical materials. We established a database of Chinese patent medicine and compound prescription (CPMCP). It demonstrates the prescription information of Chinese patent medicines (CPMs) and ancient Chinese medicine prescriptions (CMPs). CPMCP reports their comprehensive and standardized information such as the components, indications and contraindications. It is worth mentioning that we organized relevant experts and spent lots of time manually mapping the functions of compound prescriptions in ancient Chinese to the standardized TCM symptom vocabularies, obtaining a total of 71 414 associations between compound prescriptions and TCM symptoms. In this way, CPMCP established the associations between TCM and modern medicine (MM) according to the associations between TCM symptoms and MM symptoms. In addition, to further exhibit the compatibility mechanism of compound prescriptions, CPMCP summarizes a set of common drug combination principles by analyzing the existing prescriptions. We believe that CPMCP can promote the modernization of TCM and make greater contributions to MM.Database URLhttp://cpmcp.top
