Processing of Chinese medicinals with vinegar is one of the characteristic processing techniques. Vinegar is vital for the quality of vinegar-processed decoction pieces. However, there have been no specified standards for adjuvants. Through consulting relevant literature and monographs, we comprehensively reviewed the historical evolution of processing with vinegar in records, selection and application of vinegar, and summarized the relevant standards and current status of vinegar as an adjuvant in China. According to the records in literature, vinegar is effective in activating blood, moving qi, dispersing blood stasis, removing toxin, promoting appetite, and nourishing the liver. Traditionally, rice vinegar is chosen in processing. Nowadays, the vinegar made from rice under solid-state fermentation should be chosen. At present, only food standards can be taken for reference for vinegar in the processing. Integrative and specific inspection indicators are lacking, so the standards for adjuvants need to be improved urgently. In addition, the inadequacy in quality control and management is also a major problem to be solved. Through literature research, we reviewed the historical evolution and research advance in vinegar to provide a reference for the standardization and further research of vinegar used in the Chinese medicinal processing.

In recent years, the safety problems and events of traditional Chinese medicine represented by liver injury have occurred frequently. In particular, Polygonum multiflorum has been widely used and considered as a "non-toxic" tonic traditional Chinese medicine for thousands of years. However, in recent years, frequent reports of liver injury events have attracted widespread attention at home and abroad, which has made unfavorable impacts on traditional Chinese medicine and its international development. Some scho-lars have found that susceptible genes of P. multiflorum on liver injury lay a scientific foundation for formulating rational comprehensive prevention and control measures for liver injury risk of P. multiflorum and its relevant preparations. But what are the risk signals of adverse reactions of P. multiflorum in clinical application? Spontaneous reporting system is an important way to monitor and find adverse drug reaction(ADR) signals after the drug is launched in the market. It can find the ADR signals in time and effectively, and then effectively prevent and avoid the occurrence of adverse drug events. At present, the data mining technique has gradually become the main method of ADR/adverse event(AE) report analysis and evaluation at home and abroad. Specifically, Bayesian confidence propagation neural network in Bayesian method is a commonly used risk signal early warning analysis method. In this paper, BCPNN method was used to excavate the risk signals of adverse reactions of Xinyuan Capsules, a traditional Chinese medicine preparation containing P. multiflorum, such as nausea, diarrhea, rash, dizziness, vomiting, abdominal pain, headache, liver cell damage, so as to provide evidence-based evidence for clinical safe and rational use of drugs.

It is of great significance to carry out scientific investigation of threatened species and assess their in-situ conservation status in order to guide the conservation and management of these species within a region. In this study, we explored and assessed the biodiversity and in-situ conservation status of the threatened medicinal vascular plants(TMVPs) in central China. The results showed that there were 276 TMVPs in central China, including 18 critically endangered(CR), 77 endangered(EN), and 181 vulnerable(VU) species. Of which, 222 TMVPs were distributed in 49 national nature reserves, with an in-situ conservation rate of 80.43%. And the in-situ conservation rate of CR, EN and NR species were 83.33%, 77.92% and 81.22%, respectively. The complementary algorithm was used to select the nine national nature reserves with the highest protection and complementary contribution to the TMVPs. The cumulative protection contribution rate of these nine nature reserves was 81.98%. Fifty-four TMVPs were distributed outside of national nature reserves, while mainly distributed within 10 hotspot counties including Badong county, Hubei province, Sangzhi county, Hunan province, Jianghua Yao Autonomous county, Hunan province and so on. In general, TMVPs are well protected by the national nature reserves in central China. However, there are still some conservation gaps. It is necessary to carry out further field investigation on the species with conservation gaps and identify the gap areas, so as to provide scientific guidance for the optimization of the conservation of TMVPs in this region.

China has a long history of the international trade of traditional Chinese medicine(TCM).And the export products mainly composed of Chinese herbal medicine and its extracts with Chinese patent herbal medicine and health care products as complementary items.The international trade of TCM faces problems of structural disequilibrium in export products and trade barriers.In this study,we used Michael Porter's diamond model to analyze the international competitiveness of TCM industry.We found that TCM industry in China was rich in production factors and broad in market demands,but lack of the related and supporting industries.In addition,compared with the herbal medicine manufacturers in European,American and Japanese,enterprises in China were weaker in the strategy making,market positioning and industry competing.The development of the international market of herbal medicine,the arrival of the aging society,and the introduced policies of the TCM,provide great opportunities for TCM industry' s development.In order to improve the competitiveness of the TCM industry,we propose to increase the international recognition of TCM by developing clinical study,cope with international trade barrier by strengthen international standardization research,and improve the competitiveness of TCM industry by economies of scale formed by the accumulation of the pharmaceutical industry.

Dao-di herbs have been synonymous with quality medicinal herbs in our mind hearts since ancient times and are the essence of Chinese medicine culture. The development of genuine regional herbs faces problems such as insufficient supply of local resources and lack of competitive advantages. It is necessary to seek a suitable model to protect and develop authentic medicinal materials. The protection mode of geographical indication products has become more mature. Geographical indication(GI) products and authentic medicinal materials are all related to the origin. There is certain commonality between them. However, there are also differences between authentic Chinese herbal medicines and geographical indications, and it is unsuitable to simply equate the authentic Chinese medicinal materials with GI products. This article comprehensively combs and compares the development of the authentic Chinese herbal medicines and geographical indication products, and believes that it is necessary to fully learn from the experience of GI products and combine the characteristics of authentic medicinal materials to establish a set of protection systems that meet the characteristics of authentic medicinal materials. Through this research, it has positive significance to promote the protection and management of authentic medicinal materials.

Poria cocos is one of medical materials frequently used in China and well marketed at home and abroad. Based on the analysis of exports and imports data of P. cocos, we found that large proportions of P. cocos were exported, while only a small proportions of those were imported in China between 2011 and 2016. During periods of these six years, the annual exporting trade of P. cocos in quantity significantly decreased, but that in dollars tend to increase slightly and the unit-prices of P. cocos significantly increased. Statistically, the average annual export trade of P. cocos from 2011 to 2016 in quantity and dollars were 9 279.73 tons and 35.454 million dollars, respectively. And the average annual export in unit-price was 4.14 dollars per kilogram. In total, P. cocos came from 29 provinces and exported to 44 countries through 21 ports. More than 98% of total exports of P. cocos were flew to the markets of countries in Asia, of which Hong Kong was the major partner in import trade of P. cocos. Large amount of P. cocos came from Guangdong province and exported mainly through Shenzhen port. Except the exports, China also imports P. cocos from other countries, among which Korea was the major country exports largest amount of P. cocos to China. And most of P. cocos were imported by Jilin province and mainly through Changchun port. To improve the export kinetic, quality and profits of P. cocos, and thus enhance the international competitiveness of the industry of P. cocos, Chinese governments should emphasize the researches on the products of P. cocos, broaden the demand space of the high-end customers, stimulate the high-end market grow in high speed and accelerate the process of standardization in future.

To investigate the overall intestinal permeability of multiple components in lotus leaves and make clear the interaction in composition absorption process. Rat single-pass intestinal perfusion technique was used, and the results showed that the Peff values of nuciferine, demethylanuciferine, rutin, quercetin, kaempferol from lotus leaf were greater than 0.5×10⁻⁴ cm•s⁻¹. In the biopharmaceutics classification system (BCS) intestinal permeability property, these ingredients were high permeable components, while the hyperin was low permeable component. However, in the multi-component environment of the lotus leaf extract, component permeation was changed. Semi quantitative analysis of the unclear components showed that under the multi-component environment, four in seven components with relatively high contents had a Peff value less than 0.5×10⁻⁴ cm•s⁻¹, indicating these 4 components were of low permeability, while other 3 components were of high permeability. The results could be valuable to make clear the overall intestinal permeability of multiple components in lotus leaf, and lay a foundation for studying the mechanism of the lipid-lowering effect of lotus leaf.

Objective To analyze the clinical characteristics of pituitary stalk interruption syndrome(PSIS). Methods The clinical data including clinical manifestations,laboratory tests,and imaging findings of 114 PSIS patients in our hospital were retrospectively analyzed. Results Of these 114 PSIS patients,102 cases (89.4%) were male. The average age was 21.1?6.1 years. A history of breech delivery was documented in 91 cases (91.9%). Short stature was found in 89 cases (71.8%) and bone age delayed (6.1?5.1) years. Secondary sex characteristics were poor or undeveloped in most patients. The prevalence of deficiencies in growth hormone,gonadotropins,corticotropin,and thyrotropin were 100.0%,94.0%,84.2%,and 74.6%,respectively. Hyperprolactinemia was found in 28.1% of patients. Three or more pituitary hormone abnormalities were found in 105 cases(92.1%). Compared with the 5 cases with history of cephalic delivery,no difference were found in the aspects of height(t=0.297,P=0.634),penile length(t=1.205,P=0.882),testicular volume (U=99.000,P=0.348),growth hormone peak (U=89.000,P=0.186),adrenocorticotropic hormone peak(U=131.000,P=0.967),luteinizing hormone peak(U=98.500,P=0.582),thyroid-stimulating hormone (U=82.000,P=0.162),and the height of anterior pituitary (t=1.676,P=0.107) in the 53 cases with history of breech delivery. Conclusions The clinical manifestations,symptoms,hormone deficiencies were severe in our series. The condition severities were not remarkably different in patients with different delivery ways.
