[Changes of pigment components in Dendrobium catenatum flower under different storage conditions].
The flower color of Dendrobium catenatum(D. officinale) tends to fade during storage. In order to clarify the influence of storage conditions on the pigment components in flowers, two conditions were applied:temperature and illumination. The contents of pigments in the D. catenatum flower were determined by UV-Vis spectrophotometry and HPLC, and the changes of them during storage were analyzed. ⋯ After storage for 5 months, the contents of chlorophyll, carotenoid and anthocyanin constituent at-20 ℃ was significantly higher than those at 4 ℃ and room temperature. The results show that light avoiding and low-temperature can effectively slow down the degradation of pigment components. Therefore, it is suggested that D. catenatum flower should be stored in light avoiding and low-temperature conditions in actual production and processing, which can prolong the usable time.

Meta Analysis[Meta-analysis on safety of Tripterygium Glycosides Tablets in treatment of rheumatoid arthritis].
To systematically evaluate the adverse drug reaction(ADR) of Tripterygium Glycosides Tablets(TGT) in the treatment of rheumatoid arthritis(RA). Four Chinese databases(CNKI, VIP, WanFang, SinoMed) and three English databases(Cochrane Library, EMbase, PubMed), from the time of database establishing to August 2019, were systematically retrieved to collect literature on the treatment of all types of RA with TG. Screening literature and extracting data according to inclusion and exclusion criteria. ⋯ Further subgroup analysis results showed that the incidence of total ADR, especially the gastrointestinal, reproductive and cutaneous ADR of patients with treatment alone was higher than that in those paients with MTX or MTX+LEF therapy; The incidence of ADR, especially the gastrointestinal ADR, was also positively correlated with daily dose and course of treatment, while the incidence of different systems ADR was also correlated with different drug manufacturers, for instance, damage on the female reproductive system occurs most frequently in Hunan manufacture TGT administration, same as the damage on skin and accessories induced by TGT from Jiangsu manufacture. Above all, The clinical treatment of TGT for RA will cause multi-system ADR, with the highest incidence in the reproductive system, followed by the gastrointestinal system, which is closely related to the way of medication(monotherapy), daily dose, course of medication and drug manufacturer. Therefore, it is recommended that, in the treatment of RA, using TGT in combination, low dose or short-course medication, take measures to protect the reproductive system, stomach and liver, and paying attention to the drug manufacturer as well response of patients during administration should be valued to avoid ADRs to the maximum possibility.

[Textual research on Bupleuri Radix in Chinese classical prescriptions].
Through consulting the herbs and medical books of past dynasties, combining with modern literature and field investigation, this paper made textual research on the name, origin, producing area, harvesting and processing of Bupleuri Radix used in the Catalogue of Ancient Classical Prescriptions(the first batch). From Han to the Southern and Northern Dynasties, the source of Bupleuri Radix was a mixture of Bupleurum and Peucedanum, it's hard to define the origin of authentic products. In Tang Dynasty, Caryophyllaceae had been used as Bupleuri Radix. ⋯ In the Qing Dynasty, S. dichotoma was distinguished from Bupleuri Radix as another medicine. Among the prescriptions containing Bupleuri Radix included in the Catalogue of Classical Prescriptions in Ancient China(the first batch), the mainstream of genuine Bupleuri Radix should be B. scorzonerifolium and B. chinense. It is suggested that the genuine base of Bupleuri Radix should be selected according to the current resources and industrial development of Bupleuri Radix, and it should conform to the Chinese Pharmacopoeia.

[Study on mechanism of "Epimedii Folium-Paeoniae Radix Alba" in treatment of lumbar disc herniation based on network pharmacology].
The aim of this paper was to investigate the key targets and mechanism of "Epimedii Folium-Paeoniae Radix Alba" in the treatment of lumbar disc herniation by means of network pharmacology. The currently recognized databases and analysis software at home and abroad were used to construct the network from drugs and diseases. The chemical components of Epimedii Folium and Paeo-niae Radix Alba were collected by using databases such as TCMSP, while their active components were determined and the action targets were predicted according to threshold screening and literature reports. ⋯ Through KEGG pathway enrichment analysis, 91 signaling pathways related to inflammation, metabolism, and senescence were identified, mainly including IL-17 signaling pathway and TNF signaling pathway and so on. "Epimedii Folium-Paeoniae Radix Alba" showed the characteristics of multi-channel and multi-target for the treatment of lumbar disc herniation. This study preliminarily explored the key targets for its role and the biological processes and signaling pathways involved. It was found that it may play a therapeutic role by affecting inflammation and immune regulation, which laid the foundation for further experimental verification.

[HPLC fingerprint of famous traditional formula Sanpian Decoction and quality value transmitting of Chuanxiong Rhizoma].
Famous traditional formula Sanpian Decoction(SPD)comes from Dialectical Records of Chen Shiduo of the Qing Dynasty,and ranks among 100 classic prescriptions of Classic Famous Traditional Formula catalogue(the First Batch). SPD was prepared according to Management Standards for Traditional Chinese Medicine Decoction Room in Medical Institutions. ⋯ Experiment result shows that,the transfer rate of ferulic acid from medicinal herbs to decoction pieces is between 72.00% and 108.36%; the transfer rate of ferulic acid from decoction pieces to SPD is between 31.76% and 64.09%; the dry extract rate of the whole decoction is between 14.69% and 20.16%;The similarity range of fingerprint 1 of 15 batches of SPD is between 0.971 and 0.998, and the similarity range of fingerprint 2 is between 0.980 and 0.996. The established fingerprint has rich information,and the established quality evaluation method is suitable for the quality control of medicinal herbs-decoction pieces-whole decoction of Chuanxiong Rhizoma, which can provide a certain reference for developing the quality control evaluation method for formulated granules, famous formulae and other terminal products derived from traditional Chinese medicine decoction.
