Reason Analysis and Risk Prevention of Soaring Price of Traditional Chinese Medicinal Materials

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.

Connotation and scientific research points of processing of Mongolian medicinal materials

Traditional Mongolian medicine(TMM)is an important part of Chinese traditional culture,which plays an important role within the medical system of China.The processing of Mongolian medicinal materials is a pharmaceutical technology,which is the unique characteristics of Mongolian medicine.In this paper,the basic concepts related to the processing of Mongolian medicinal materials were introduced,and its scientific research points were put forward,in order to deeply excavate the connotation of Mongolian pharmacy and further study the processing mechanism of Mongolian medicinal materials,so as to provide important basis for the development of Chinese traditional medicine.The essence of Mongolian medicinal materials processing is to use drugs safely and dialectically to ensure the quality of Mongolian medicinal materials.The scientific research sites of Mongolian medicinal materials processing have two categories:reducing toxicity(increasing)effect and synergistic effect of excipients and processing factors.Because of the not perfect research platform of Mongolian medicinal materials and the weak processing power,the development of research of Mongolian medicinal materials is relatively slow.Therefore,there are many research breakthroughs in the interdisciplinary research on the processing of Mongolian medicinal materials,and it is expected to become a research hotspot.

Bioactive constituents of animal-derived traditional Chinese medicinal materials for breast cancer:opportunities and challenges

Breast cancer is globally the most common invasive cancer in women and remains one of the leading causes of cancer-related deaths.Surgery,radiotherapy,chemotherapy,immunotherapy,and endocrine therapy are currently the main treatments for this cancer type.However,some breast cancer patients are prone to drug resistance related to chemotherapy or immunotherapy,resulting in limited treatment efficacy.Consequently,traditional Chinese medicinal materials(TCMMs)as natural products have become an attractive source of novel drugs.In this review,we summarized the current knowledge on the active components of animal-derived TCMMs,including Ophiocordyceps sinensis-derived cordycepin,the aqueous and ethanolic extracts of O.sinensis,norcantharidin(NCTD),Chansu,bee venom,deer antlers,Ostrea gigas,and scorpion venom,with reference to marked anti-breast cancer effects due to regulating cell cycle arrest,proliferation,apoptosis,metastasis,and drug resistance.In future studies,the underlying mechanisms for the antitumor effects of these components need to be further investigated by utilizing multi-omics technologies.Furthermore,large-scale clinical trials are necessary to validate the efficacy of bioactive constituents alone or in combination with chemotherapeutic drugs for breast cancer treatment.

Discussion on evolution of Mongolian medicinal material names and countermeasures for standardization

Mongolian pharmacy is an important part of traditional medicine for the Chinese nation,with a long history and a complete theoretical system.The Mongolian people have accumulated and summarized the types and usage of Mongolian medicines in the practice of fighting against diseases over a long history.Mongolian medicinal resources are rich and diverse,the processing is self-contained,and the methods of medication are scientific and reasonable.Mongolian pharmacy not only has a deep historical relationship with traditional Chinese medicine but has also absorbed the essence of ancient Tibetan and Indian Ayurvedic medicine in the process of its development.We can identify the historical traces of the continuous exchange,communication,and integration of various ethnic medicinal cultures from the names of Mongolian medicinal materials.Because of the differences in languages and cultures of the various ethnic groups,the names of Mongolian medicinal materials have undergone a long historical period of evolution.These need to be further standardized owing to complications caused by the existence of synonyms and homonyms.

Spectrofluorimetry and High-Performance Liquid Chromatography in the Detection of Aflatoxins in Chinese Medicinal Materials

Objective: To analyze the effect of spectrofluorimetry and highperformance liquid chromatography in the detection of aflatoxin in Chinese medicinal materials. Methods: The content of aflatoxin in Chinese medicinal materials was determined by spectrofluorimetry and high-performance liquid chromatography respectively, and the effects of the two detection methods were compared. Results: The results of sample detection by spectrofluorimetry showed that except for Angelica and Sophora flavescens with "detection dada error", the other 25 kinds of Chinese medicinal materials were positive for aflatoxin, but the types of aflatoxin derivatives could not be distinguished, and the tested content was generally high. The recovery experiment of mixed reference substance based on the concentration levels showed that the recovery rate of aflatoxin was 93.60%-99.70% in the case of high-performance liquid chromatography,and the RSD was 1.83%-6.70%. The sample detection results by high-performance liquid chromatography showed that among the 18 kinds of Chinese medicinal materials,only Radix Peucedani, almond, barley, raw Jianqu and aflatoxin were positive, and the types of aflatoxin derivatives could be accurately differentiated. Conclusion: Compared with spectrofluorimetry, high-performance liquid chromatography is more accurate in the determination of aflatoxin content in Chinese medicinal materials, which can distinguish the types of aflatoxin derivatives.

Comparison of Sulfur Dioxide Residue in Chinese Me-dicinal Materials by Titration-fluorescence Spectrome-try and Pharmacopoeia Method

With sulphur-fumigated Chinese medicinal materials （Fritillaria thunbergii , Isatis #utigotica , Asparagus cochinchinensis and Poria cocos ） as the test materials, sulfur dioxide or sulfite residue was determined by the method in Chinese Pharmacopoeia （2015 edition） and titration-fluorescence spectrometry, respec- tively. The results showed that there were significant differences in measured value between titration-fluorescence spectrometry and phmmacopoeia method. The t result of titration-fluorescence spectrometry was much closer to the actual content of sulfur dioxide in Chinese medicinal materials. Thus, titration-fluo- rescence spectrometry had higher application value

Roles of endophytic fungi in medicinal plant abiotic stress response and TCM quality development

Medicinal plants,as medicinal materials and important drug components,have been used in traditional and folk medicine for ages.However,being sessile organisms,they are seriously affected by extreme environmental conditions and abiotic stresses such as salt,heavy metal,temperature,and water stresses.Medicinal plants usually produce specific secondary metabolites to survive such stresses,and these metabolites can often be used for treating human diseases.Recently,medicinal plants have been found to partner with endophytic fungi to form a long-term,stable,and win-win symbiotic relationship.Endophytic fungi can promote secondary metabolite accumulation in medicinal plants.The close relationship can improve host plant resistance to the abiotic stresses of soil salinity,drought,and extreme temperatures.Their symbiosis also sheds light on plant growth and active compound production.Here,we show that endophytic fungi can improve the host medicinal plant resistance to abiotic stress by regulating active compounds,reducing oxidative stress,and regulating the cell ion balance.We also identify the deficiencies and burning issues of available studies and present promising research topics for the future.This review provides guidance for endophytic fungi research to improve the ability of medicinal plants to resist abiotic stress.It also suggests ideas and methods for active compound accumulation in medicinal plants and medicinal material development during the response to abiotic stress.

Geochemical characteristics and growth suitability assessment of Scutellaria baicalensis Georgi in the Earth's critical zone of North China

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.

A Systematic Review of Animal and Clinical Studies on the Use of Scaffolds for Urethral Repair

Replacing urethral tissue with functional scaffolds has been one of the challenging problems in the field of urethra reconstruction or repair over the last several decades. Various scaffold materials have been used in animal studies, but clinical studies on use of scaffolds for urethral repair are scarce. The aim of this study was to review recent animal and clinical studies on the use of different scaffolds for urethral repair, and to evaluate these scaffolds based on the evidence from these studies. Pub Med and OVID databases were searched to identify relevant studies, in conjunction with further manual search. Studies that met the inclusion criteria were systematically evaluated. Of 555 identified studies, 38 were included for analysis. It was found that in both animal and clinical studies, scaffolds seeded with cells were used for repair of large segmental defects of the urethra, such as in tubular urethroplasty. When the defect area was small, cell-free scaffolds were more likely to be applied. A lot of pre-clinical and limited clinical evidence showed that natural or artificial materials could be used as scaffolds for urethral repair. Urinary tissue engineering is still in the immature stage, and the safety, efficacy, cost-effectiveness of the scaffolds are needed for further study.

Tumor-suppressor effects of chemical functional groups in an in vitro co-culture system

Liver normal cells and cancer cells co-cultured on surfaces modified by different chemical functional groups, including mercapto （-SH）, hydroxyl （-OH） and methyl （-CHz） groups. The results showed that different cells exhibited changes in response to different surfaces. Normal cells on -SH surface exhibited the smallest contact area with mostly rounded morphology, which led to the death of cancer cells, while cancer cells could not grow on -CH3 groups, which also died. In the co-culture system, the -CH3 group exhibited its unique effect that could trigger the death of cancer cells and had no effects on normal cells. Our findings provide useful information on strategies for the design of efficient and safe regenerative medicine materials.
