Sophorae Flavescentis Radix is one of the commonly used traditional Chinese medicine in China, and a large amount of pharmaceutical residue generated during its processing and production is discarded as waste, which not only wastes resources but also pollutes the environment. Therefore, elucidating the chemical composition of the residue of Sophorae Flavescentis Radix and the differences between the residue and Sophorae Flavescentis Radix itself is of great significance for the comprehensive utilization of the residue. This study, based on ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) technology combined with multivariate statistical methods, provides a thorough characterization, identification, and differential analysis of the overall components of Sophorae Flavescentis Radix and its residue. Firstly, 61 compounds in Sophorae Flavescentis Radix were rapidly identified based on their precise molecular weight, fragment ions, and compound abundance, using a self-constructed compound database. Among them, 41 compounds were found in the residue, mainly alkaloids and flavonoids. Secondly, through principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA), 15 key compounds differentiating Sophorae Flavescentis Radix from its residue were identified. These included highly polar alkaloids, such as oxymatrine and oxysophocarpine, which showed significantly reduced content in the residue, and less polar flavonoids, such as kurarinone and kuraridin, which were more abundant in the residue. In summary, this paper clarifies the overall composition, structure, and content differences between Sophorae Flavescentis Radix and its residue, suggesting that the residue of Sophorae Flavescentis Radix can be used as a raw material for the extraction of its high-activity components, with promising potential for development and application in cosmetics and daily care. This research provides a scientific basis for the future comprehensive utilization of Sophorae Flavescentis Radix and its residue.

At present, 141 compounds have been isolated from Picrorhiza scrophulariiflora and P. kurroa of the Scrophulariaceae plants, including 46 iridoid glycosides, 29 tetracyclic triterpenoids, 25 phenylpropanoids, and 11 phenylethanoid glycosides. Pharmacological studies have demonstrated that they have liver-, heart-, brain-, kidney-, and nerve cells-protecting effects as well as anti-tumor, anti-inflammatory, anti-bacterial, anti-asthma, anti-diabetic, immunomodulatory, and blood lipid-lowering activities. This article reviews the chemical components and pharmacological activities of P. scrophulariiflora and P. kurroa, aiming to provide a basis for the in-depth research, development, and utilization of the two plants.

Objective:
To evaluate the safety and effectiveness of a vaccine based on latent membrane protein 2 (LMP2) modified dendritic cells (DCs) that boosts specific responses of cytotoxic T lymphocytes (CTLs) to LMP2 before and after intradermal injection in patients with nasopharyngeal carcinoma (NPC).
Methods:
DCs were derived from peripheral blood monocytes of patients with NPC. We prepared LMP2-DCs infected by recombinant adenovirus vector expressing LMP2 (rAd-LMP2). NPC patients were immunized with 2 × 10
Results:
We demonstrated that DCs derived from monocytes displayed typical DC morphologies; the expression of LMP2 in the LMP2-DCs vaccine was confirmed by immunocytochemical assay. Twenty-nine patients with NPC were enrolled in this clinical trial. The LMP2-DCs vaccine was well tolerated in all of the patients. Boosted responses to LMP2 peptide sub-pools were observed in 18 of the 29 patients with NPC. The follow-up data of 29 immunized patients from April, 2010 to April 2015 indicated a five-year survival rate of 94.4% in responders and 45.5% in non-responders.
Conclusion
In this pilot study, we demonstrated that the LMP2-DCs vaccine is safe and effective in patients with NPC. Specific CTLs responses to LMP2 play a certain role in controlling and preventing the recurrence and metastasis of NPC, which warrants further clinical testing.

Salviae Miltiorrhizae Radix et Rhizoma (Danshen) is one of the commonly used bulk medicinal materials in China. It is widely used in clinical practice, and has many pharmacological effects, such as antithrombotic,antibacterial,anti-inflammatory,anti-oxidative and immunomodulatory activities. The quality of Danshen determines the quality of the curative effect. The current wild resources of Danshen gradually decrease, the cultivation area is widely distributed, among them, Shandong, Sichuan, Anhui, Shanxi, Hebei, Henan and other provinces have large acreage for Danshen. However, germplasm, origin, cultivation, harvest, process and other factors have a certain impact on the active ingredients of Danshen, which lead to the quality of Danshen good and bad mixed. This paper is based on the systematic analysis of literature on quality evaluation of Danshen. To provide a new idea for the further research on the quality of Danshen, we summarized the main factors affecting the quality of Salvia miltiorrhiza that of germplasm, origin, cultivation, harvest, process, storage, product specifications and so on.

Epimedii Folium has a long history in China as a common traditional Chinese medicine. Key factors of Epimedii Folium quality were summarized based on ancient literatures, Chinese Pharmacopoeias and modern research in different period of history. The main reason for unqualified Epimedii Folium is unstable icariin. Therefore, it's suggested that: the precondition of the quality control of epimedium is to find the proper quality marker. It's suggested that the medicinal parts should be reverted to "dry whole plant overground" to solve Epimedium resource shortage problem. In addition, it is necessary to strengthen the standardized cultivation, so as to ensure germplasm, production area, and producing method to guarantee the quality of Epimedium Folium. In the drying method, it is recommended to change "dry in the sun or shade" to "dry", namely dry in the sun, shade or drier, in order to provide a new method to improve the quality control and quality standard of Epimedii Folium.

This paper is aimed to develop a method for the determination of five effective components in medicinal material of Tripterygium using ultra performance liquid chromalography coupled with electrospray ionization tandem mass spectrometry(UPLC-ESI-MS/MS), which then was used to study their contents in raw materials from different areas and different sources.The separation was performed on a Waters ACQUITY UPLC-CSH-C18S column(2.1 mm×100 mm,1.7 μm), usingacetonitrile-0.2% ammonium form ateaqueous solutionas mobile phase. The target components were detected in multiple-reaction monitoring(MRM) mode by mass spectrometry with electrospray ionization (ESI) source operated in positive ionization mode. The quantitative results showed that good linearity was achieved in their respective linear ranges and fine determination coefficient (r > 0.997 8),and the overall recoveries ranged from 96.72%-103.2% with the RSD ranging from 1.0%-2.4%.The method is sensitive and accurate, and suitable for the effective components quantification in medicinal material of Tripterygium; contents of five effective components from different sources vary significantly, so the quality and safety of medicinal material of Tripterygium needs to be improved. It is very important to control the quality with multi-index for clinic safety.

The current situation of the standardization of acupuncture and moxibustion in the Taiwan region is introduced in this paper from the three aspects, named the development state of standard of acupuncture and moxibustion in Taiwan, the implementation of Taiwan district standard and the standardization of acupuncture and moxibustion in Taiwan. At present, the relevant standards of acupuncture and moxibustion in Taiwan just include the standard operation procedure of acupuncture and moxibustion, the reference guideline of the safe operation in the medical service centers of traditional Chinese medicine, and the faculty standard of Chinese medicine hospital, etc. It is concluded that the current situation of the standardization of acupuncture and moxibusiton presented the weak awareness of the standardization of acupuncture and moxibustion in the industry, insufficient enterprise standard, less-quantity of the implemented standards and narrow coverage.
