Analysis on Composition Rules of Chinese Patent Drugs Treating Pain-Related Diseases Based on Data Mining Method.

OBJECTIVE: To analyze the composition rules of oral prescriptions in the treatment of headache, stomachache and dysmenorrhea recorded in National Standard for Chinese Patent Drugs (NSCPD) enacted by Ministry of Public Health of China and then make comparison between them to better understand pain treatment in different regions of human body. METHODS: Constructed NSCPD database had been constructed in 2014. Prescriptions treating the three pain-related diseases were searched and screened from the database. Then data mining method such as association rules analysis and complex system entropy method integrated in the data mining software Traditional Chinese Medicine Inheritance Support System (TCMISS) were applied to process the data. RESULTS: Top 25 drugs with high frequency in the treatment of each disease were selected, and 51, 33 and 22 core combinations treating headache, stomachache and dysmenorrhea respectively were mined out as well. CONCLUSIONS: The composition rules of the oral prescriptions for treating headache, stomachache and dysmenorrhea recorded in NSCPD has been summarized. Although there were similarities between them, formula varied according to different locations of pain. It can serve as an evidence and reference for clinical treatment and new drug development.

[Discussion on assessment method of Chinese medicine resources].

At the end of 2017, the former China Food and Drug Administration promulgated " the Guiding Principles for the Assessment of Chinese Medicine Resources" whose purpose is establishing the concept of " the production of Chinese traditional medicines, herbal pieces and etc. should be based on the premise of ensuring the production and quality of Chinese medicine resources" for a licensed holder of a drug listing or a production enterprise of Chinese Medicine by assessing this work through the resources of Chinese Medicine which finally achieves the strategic significance of promoting the sustainable utilization of Chinese medicine resources. Under the guidance of the overall idea of "the total amount is not reduced and the supply is guaranteed", this paper focuses on the following two methods of assessment: ①"family property assessment" of Chinese medicine resources based on "fixed total amount". ② "Supply and demand balance assessment" of Chinese medicine resources based on "supply guarantee". In this paper, we discuss the difference and relationship between the national survey of Chinese medicine resources and the assessment of Chinese medicine resources. Finally, we put forward a basic strategy called" supply and demand balance assessment" of Chinese medicine resources based on "supply guarantee" that will guide the Industrial production of traditional Chinese medicine.

[Status and thinking of quality supervision on imported medicinal materials in shortage].

With the continuous development of traditional Chinese medicine business, the types and amounts of Chinese materia medica resources are increasingly reduced. By reviewing the origins, trading sources, and existing quality standards of the available common Chinese madicinal materials in shortage, it was found that the large amount of imported medicinal materials in domestic market or clinical application were not due to the traditional paths such as envoys presenting tribute, business trade, war conflict, national migration, and tourist travel, but due to the shortage of resources in domestic origins. Meanwhile, the former quality control standard on traditional imported medicinal materials was out of date, and the new imported medicinal materials quality control standard was in absence, resulting in unclear origins, unknown origins and processing methods, as well as more and more prominent problems on mixed use of the different varieties with same name and the same varieties from different origins. On the one hand, this situation once again sounded the alarm for the development of Chinese medicine industry from the resource perspective. On the other hand, the confusion of new varieties in Chinese herbal medicine market has also brought a serious threat to the efficacy of Chinese medicine. It is pointed out that it is an effective way to ensure the drug safety of imported medicinal materials through strengthening quality supervision of shortage of traditional Chinese medicines based on the new pharmacopoeia standards.

Identification of certain Panax species to be potential substitutes for Panax notoginseng in hemostatic treatments.

Panax notoginseng (Burkill) F. H. Chen ex C. H. Chow (P. notoginseng) is a highly valued Chinese materia medica having a hemostatic effect and mainly used for the treatment of trauma and ischemic cardiovascular diseases. Stringent growth requirements, weak resistance to insect pests and plant diseases, arsenic contamination and continuous cropping constitute hurdles to further increases in the agricultural production of P. notoginseng. This review focuses on the traditional uses (based on traditional Chinese medicine theory), major chemical components, biological activities, pharmacological properties, geographical distributions and historical development of taxonomy of P. notoginseng and its related species in Panax genus, including Panax japonicus C. A. Meyer (P. japonicus), Panax japonicus C. A. Meyer var. major (Burkill) C. Y. Wu et K. M. Feng (P. japonicus var. major) and Panax japonicus C. A. Meyer var. bipinnatifidus (Seem.) C. Y. Wu et K. M. Feng (P. japonicus var. bipinnatifidus) are reviewed. This review sheds light on the origin herbs of Zhujieshen (ZJS) and Zhuzishen (ZZS), e.g., P. japonicas var japonicas, P. japonicus var. major and P. japonicus var. bipinnatifidus could be used as a substitute for P. notoginseng as hemostatic herbs.

[Exploration and research on comprehensive evaluation model of Chinese patent medicines supply in national essential drugs].

Chinese medicine prices often have sharp rise or fall, and even the impact of short-term price rise on the quality of feed can't be ignored.On the other hand, the production of traditional Chinese medicine is strictly subject to resource constraints, so much of the industrial production due to lack of or prohibited use of resources must bestopped. Based on 203 Chinese patent medicines in the National Essential Drugs (2012 Edition), the factors that influence the supply of essential drugs of traditional Chinese medicine were analyzed and seven indicators for the supply of essential medicines were designed in this paper. According to the Chinese herbal medicine resources survey and dynamic monitoring service system data, a multi-index comprehensive evaluation model based on radar chart analysis was proposed, providing a holistic and overall evaluation of the supply situation of essential drugs of traditional Chinese medicine. The evaluation results were concise, clear and intuitive. In this paper, Jiuwei Qianghuo Wan and Ganmao Qingre Keli were taken as the examples to prove that the proposed comprehensive evaluation method is concise, clear, intuitive, credible and practical.

Taxonomic examination of longgu (Fossilia Ossis Mastodi, "dragon bone") and a related crude drug, longchi (Dens Draconis, "dragon tooth"), from Japanese and Chinese crude drug markets.

Longgu ("dragon bone," Ryu-kotsu, Fossilia Ossis Mastodi, or Os Draconis) is the only fossil crude drug listed in the Japanese Pharmacopoeia. All longgu in the current Japanese market is imported from China, where its resources are being depleted. Therefore, effective countermeasures are urgently needed to prevent resource depletion. One possible solution is the development of a substitute made from bones of contemporary animals that are closely related to the original animal source of the current longgu. However, no research has been conducted on the original animal source of longgu, except for a report on the longgu specimens present in the Shosoin Repository. Taxonomic examination was performed on the fossil specimens related to longgu which are owned by the Museum of Osaka University, Japan. In total, 20,939 fossil fragments were examined, of which 20,886 were mammalian fossils, and 246 of these fossils were classified into nine families. The longgu specimens from the Japanese market belonged to a relatively smaller variety of taxa than those from the Chinese market. Despite the variety of taxa in longgu, medical doctors using Kampo preparations with longgu have not reported any problems due to the presence of impurities in the original animal source. These results suggest that the effect of longgu is independent of its origin as long as it is closely related to the origin of the current longgu. Thus, despite the considerable effects of fossilization, our results could help in developing an optimal substitute for longgu.

[Design and implementation of supply security monitoring and analysis system for Chinese patent medicines supply in national essential medicines].

The supply of Chinese patent medicine is influenced by the price of raw materials (Chinese herbal medicines) and the stock of resources. On the one hand, raw material prices show cyclical volatility or even irreversible soaring, making the price of Chinese patent medicine is not stable or even the highest cost of hanging upside down. On the other hand, due to lack of resources or disable some of the proprietary Chinese medicine was forced to stop production. Based on the micro-service architecture and Redis cluster deployment Based on the micro-service architecture and Redis cluster deployment, the supply security monitoring and analysis system for Chinese patent medicines in national essential medicines has realized the dynamic monitoring and intelligence warning of herbs and Chinese patent medicine by connecting and integrating the database of Chinese medicine resources, the dynamic monitoring system of traditional Chinese medicine resources and the basic medicine database of Chinese patent medicine.

[Study on spatial distribution characteristics of traditional Chinese medicine resource species richness based on national census of Chinese medicine resources (pilot)].

Based on the data collected by the census team in the national census information management system, the spatial autocorrelation analysis method was used to analyze the similarity of the richness of Chinese herbal medicine resources in the investigated counties. The results showed that the species richness in the investigated counties appeared a tendency to focus on the distribution of the characteristics. Among them, the areas with sparse resources are concentrated in most areas of the north of the Yangtze River, northwest and most areas of Tibet. The areas with abundant resources are concentrated in the areas south of the Yangtze River. The results showed that there were significant differences in the abundance of traditional Chinese medicine resources between regions. The results showed that there were significant differences in the abundance of traditional Chinese medicine resources between regions. Due to the large differences in the land area between the county and the richness of the types of traditional Chinese medicine resources, it is proposed to increase the land area of the traditional Chinese medicine resource census when allocating the fourth national census of Chinese medicine resources by the "factor method", and the richness of traditional Chinese medicine and other indicators, in order to give full play to the efficiency of transfer payment system. Based on the county area and the rich variety of traditional Chinese medicine resources, combined with the national drug resources census pilot work carried out, it is recommended to focus on attention and support in the national medicine resources census work, personnel team, funding, summary of results on the western and southern provinces.

[Shortage of Chinese medicine of the 1950s and the 20-year "Xiao qiu shou (minor autumn harvest)"].

To encourage the collection and improve of purchase are the important measures to solve the shortage of Chinese medicine. In 1958, due to the large amount of rural manpower invested in the campaign of construction of water conservancy projects and the large-scale steel-making and iron-smelting, the planting of traditional Chinese medicine was thus reduced, resulting in a shortage of medicinal herbs. To alleviate the serious shortage of traditional Chinese herbals and severe situation, the State Council issued an instruction, urging to utilize and collect wild plants, raw materials in 1958, followed by another order, advocating to carry out the "Xiao qiu shou(minor autumn harvest)" the next year, including the harvesting of wild crude medicinal herbs. In the 20 years since then, the minor autumn harvest had been widely carrying out in the harvesting of wild medicinal herbs, which became the main way to solve the shortage of Chinese medicinal materials, and had played an important role in alleviating the tough supply of medicinal herbs.

[Pesudostellariae Radix industry status and development countermeasures].

In recent years, with increasing role in traditional Chinese medicine industry of many provinces in china, Pseudostellariae Radix is one of the rapid development traditional Chinese medicine. Based on references and on-site investigation of main producing area, we clear the process of change from the small of the Panax ginseng to the Pseudostellariae Radix in aspects of history, and the change of producing area from Shandong, Jiangsu provinces to Fujian, Anhui and Guizhou provinces. And we clear how the Pseudostellariae Radix become a commonly used Chinese medicinal herbs from a small variety based on the market supply and demand and price changes, and it has gradually become a hot topic of the research. This paper summarized the status quo and the existing problems in the Pseudostellariae Radix industry. On this basis, we put forward countermeasures and suggestions for the development of the Pseudostellariae Radix industry.

Consumption of Chinese herbal medicines during pregnancy and postpartum: A prospective cohort study in China.

OBJECTIVE: to investigate usage patterns and factors associated with maternal consumption of Chinese herbal medicines in China. DESIGN: prospective cohort study. Information on the use of Chinese herbal medicines was collected from mothers by personal interview at hospital discharge and followed up by telephone at one, three and six months postpartum. SETTING: seven hospitals in Jiangyou, Sichuan Province of China. PARTICIPANTS: 695 mothers who gave birth to a singleton infant. MEASUREMENTS: prevalence, type, frequency and duration of herbal medicine usage. Logistic mixed regression analyses were performed to determine factors affecting the use. FINDINGS: a total of 43.5% and 45.0% of mothers consumed Chinese herbal medicines during pregnancy and postpartum, respectively. Angelica sinsensis was the most popular herbal medicine among the participants (pregnancy 28.8%, postpartum 26.8%). Although herbal medicines were taken more regularly by postpartum users, the median usage duration varied from two to three months during pregnancy but 1-1.6 months postpartum. The majority of users (pregnancy 42.9%, postpartum 55.1%) were advised by their mother or mother-in-law to take Chinese herbal medicines. Antenatal alcohol drinking (adjusted odds ratio 2.75, 95% confidence interval 1.01-7.53) was associated with a marginally higher prevalence of herbal consumption during pregnancy, whereas mothers with a lower family income (adjusted odds ratio 1.52, 95% confidence interval 1.12-2.04) were more likely to consume Chinese herbal medicines in the postpartum period. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: consumption of Chinese herbal medicines appears to be prevalent among Chinese mothers, especially those drinking alcohol whilst pregnant and women from a lower income household. Maternity health professionals need to be aware of the lack of evidence to support the use of Chinese herbal medicines during pregnancy and postpartum, and to provide their clients with scientifically based advice regarding herbal medicine use.

[Study of changes in Chinese herbal medicine distribution channel].

Distribution channel of Chinese herbal medicines has been changing. From Han to Ming Dynasty, Chinese herbal medicine were mainly trafficked to urban by dealers or farmers; From the Ming Dynasty to the foundation of new China, distribution channels are primarily intermediated with township "bazaar" and national distribution center with fixed place and regularly trading hours. In the planned economy period, the state-owned herbal medicine company was the sole medium with monopoly nature. From the mid1980s to the end of last century, planned economy and market economy have been co-existing. Stepping into 21st century, producing area highlighted in the distribution channels. Presence or absence and rise or fall of different types of distribution market went throughout the changing process of distribution channels, which became an important clue. Changes were motivated by economical consideration of channel subject, which originated from commodity characteristic and social environment changes.

[Evaluation of Bupleuri Radix resources in Qingchuan based on DTOPSIS and grey related degree].

In order to select high quality and suitable Bupleuri Radix varieties in Qingchuan, and establish a new comprehensive method to evaluation the quality of Bupleuri Radix, 12 characters of 14 samples were evaluated by DTOPSIS and grey related degree. The results showed that varieties No. 8 and No. 10 had high quality. DTOPSIS and grey related degree gave the uniformity result, and the biggest difference of value of Ci in DTOPSIS method was 46. 33% , but the biggest difference of the weighting correlation number( r (i)) in grey related degree was only 13.10%. The DTOPSIS combined with grey related degree can evaluate the quality of Bupleuri Radix comprehensively and objectively.

[Research on our hospital inventory management status quo of traditional Chinese medicine drugs and treatment method].

Under the background of the new medical reform, a large variety of traditional Chinese medicine from complicated sources, Chinese traditional medicine of actor of true and false of the quality directly affect the drug safety and clinical efficacy, but also relate to the social and economic benefits of hospital. Along with the development of the modern management of medical institutions and drug circulation circulation system reform in our country, the hospital drug inventory, supply and management work is an important topic for the pharmaceutical trading. However, there is always contradiction, dispensary need to supple pharmacy, in order to satisfy the demands of hospital patients with normal diagnosis and treatment work. However, if the drug inventory is too much, not only increases the drug monitoring problem, at the same time, but also causes storage costs rise. Therefore, completing scientific and reasonable storage and management becomes urgent problems at present. Wherefore, our country administration of traditional Chinese medicine in 2007 promulgated the "Chinese traditional medicine yinpian management norms in hospital", aims to standardize management of Chinese traditional medicine quality and improve the safety of drugs. The author through looking up information and visiting survey, to understand the currently existing problems, and summarizes the literature inland and abroad in recent years Chinese medicine drug inventory management work experience, in view of status quo of Chinese medicine inventory management in China, put forward the solution. To guarantee TCM pharmacy management more standardized, more standard, to adapt to the new reform of Chinese traditional medicine industry, improve the management level of hospital, defend the hospital's reputation and the patient's interests.

[Project design and implementation of the fourth national survey Chinese matiera medica resources].

The planning of the fourth national survey on Chinese materia medica resources shall follow the requirement of "carrying out the national survey on Chinese materia medica resources, strengthening the construction of Chinese materia medica resources monitoring and information network" which is according to the document issued by the State Council. Based on the responsibilities of State Administration of Traditional Chinese Medicine which is "organizing the survey, promoting the resource-protection, keeping development and rational utilization", combined with the key problems that need to be solved in current medicinal industry, the related instructions issued by central leadership and the recommendations from NPC delegates, CPPCC members and experts, the planning shall make overall plans and top-level design for the new round of national survey on Chinese materia medica resources.

[Investigation on wild resources of Dendrobium officinale distribution and ecological envirment in Anhui].

The wild resources of Dendrobium officinale in Anhui province were studied by textural research, data collection, interview survey and regional survey, in order to investigate the resources distribution and ecological characters and provide the reference for Anhui Dendrobium industry. In this paper, a part of producing areas of wild D. officinale in Anhui province was selected to analyze the ecological characters. As a result, we find that the wild resources of D. officinale in Anhui distributed only sporadic and the conditions of growth environment were harsh. Our findings may provide some suggestions on wild resources protection and artificial cultivation in suitable environments because the wild resources of D. officinale in Anhui are decreasing rapidly and facing an endangered situation.

[Dao-di herbs and its change of cultivated origin place].

The origin place change is an almost universal rule for many Chinese medicines according to the formation and change history of ancient and recent Dao-di herbs. Among them, the quality and output are the essence and driving force of the formation and change of Dao-di herbs origin place. More and more species and quantities of Chinese medicine were cultivated along with development of Chinese medicine and modern manufacturing technology, and its production regions far exceed natural location zones, the rationality of origin place change should be based on drug quality evaluation. Under the guidance of the formation mode of Dao-di herbs, characteristics of Dao-di herbs were summarized, its characteristics and applied limits were suggested, some traditional Chinese medicinal materials only with higher output, cultivated materials in distribution area for wild, or materials with poor genetic resources failing to answer with Dao-di herbs. Chinese medicines authenticity should strengthen the study of germplasm and drug quality assessment, the suitability of producing area should be assessed according to output and quality under the guidance of suitable locations regionalization.

[Studies on chemical components and pharmacological activities of Os Draconis (Longgu) and Ostreae Concha].

The source of Os Draconis (Longgu) has been greatly limited along with implementation of the regulation on the protection of fossils from January 1, 2011. Fingding substitute for Os Draconis becomes an urgent problem. Here, we summarized drug properties of Os Draconis and Ostreae Concha. Moreover the two herbs were usually compatible application in the clinical treatment since they possess similar chemical components and pharmacological activties. In term of these researches, Ostreae Concha may be substitute candidate for Os Draconis.

[Surveys on resources and varieties on Chinese markets of crude drug mahuang].

Many species of the genus Ephedra plants are used as Chinese traditional medicines, in Chinese which are known as "Mahuang" (Ephedrae Herba). In order to get a clear picture of resources distribution and varieties on Chinese markets of the crude drug Mahuang and provide scientific basis for their resource conservation and sustainable use, during recent years we conducted field investigations and market researches many times. The results showed that the most common species on the Chinese markets was E. sinica (33/38 commercial samples), followed by E. intermedia (5/38 commercial samples), which was also used in local clinics in Qing-hai, Gansu and Xinjiang province, no E. equisetina was found in the market. We noticed that the resources of both official and non-official plants of Mahuang, especially Zhong-Mahuang and Muzei-Mahuang, were seriously damaged in the past decade because of the ecological environment damage and over-digging. Zhong-Mahuang was distinguished in Ningxia and north Gansu, which was once one of the most distribution areas and contains more than 10,000 t Zhong-Mahuang. Muzei-Mahuang was distinguished in most places and distributed sparsely around Altay Mountains in northeast in Xinjiang. Thus, Cultivation of Mahuang, especially Zhong-Mahuang and Muzei-Mahuang should be greatly developed. At the same time, wild resources of Mahuang must be preserved strictly, i.e., proper method of cutting Ephedra plant could prevent the damage of the resource.

GAP production of TCM herbs in China.

In this paper, we briefly review international Good Agricultural Practice (GAP) regulations related to traditional Chinese medicine herbs (TCM herbs) and the background of the drafting process and the implementation of GAP for TCM herbs in China. We also have summarized progress and achievements since the implementation of GAP for TCM herbs in 2002. Up to 2010, a total of 99 GAP bases were formally adopted by GAP certification. They cover 22 provinces/municipalities, and 49 species of TCM herbs are currently cultivated in these GAP bases. Finally, we discuss the main problems in GAP implementation for Chinese crude drugs and put forward some suggestions to tackle them.
