ABSTRACT
In the digital transformation of Chinese pharmaceutical industry, how to efficiently govern and analyze industrial data and excavate the valuable information contained therein to guide the production of drug products has always been a research hotspot and application difficulty. Generally, the Chinese pharmaceutical technique is relatively extensive, and the consistency of drug quality needs to be improved. To address this problem, we proposed an optimization method combining advanced calculation tools(e.g., Bayesian network, convolutional neural network, and Pareto multi-objective optimization algorithm) with lean six sigma tools(e.g., Shewhart control chart and process performance index) to dig deeply into historical industrial data and guide the continuous improvement of pharmaceutical processes. Further, we employed this strategy to optimize the manufacturing process of sporoderm-removal Ganoderma lucidum spore powder. After optimization, we preliminarily obtained the possible interval combination of critical parameters to ensure the P_(pk) values of the critical quality properties including moisture, fineness, crude polysaccharide, and total triterpenes of the sporoderm-removal G. lucidum spore powder to be no less than 1.33. The results indicate that the proposed strategy has an industrial application value.

Xiexin decoctions (XXDs) display beneficial anti-inflammatory and anti-diabetic effects, which raises interests on this group of formulae for broad clinical applications. However, there was no report about systematic analysis of XXDs to elucidate the constitution of chemical components, which hampers further investigations on the therapeutic values of XXDs. In this work, crude herbs were extracted and prepared to obtain the XXDs for systemic analysis on their chemical compositions, according to the information described in the ancient Zhang Zhongjing's herbal formulae. LC-MS analysis of five XXDs was carried out to facilitate recognition of the source herbs for compounds in the mixture. A total number of 93 compounds were identified through our methods and their chemical classes encompassed five major groups, including protoberberine alkaloids, flavonoids, stilbenes, anthraquinones and saponins. Our current work provided important information about material basis for pharmacological studies on XXDs and would help shed light on relationships between chemical compositions and therapeutic effects.

The study aimed to investigate the multi-constituent, multi-target mechanism of Xuanfei Baidu Tang(XFBD) in the treatment of coronavirus disease 2019(COVID-19), through exploring the main ingredients and effective targets of XFBD, as well as analyzing the correlation between XFBD targets and COVID-19. The compounds of each herb in XFBD were collected from TCM-PTD, ETCM, TCMSP and SymMap database. Next, the information of meridian tropisms was collected from Chinese Pharmacopoeia(2015 edition), and the target information of the major constituents of XFBD were obtained from TCM-PTD, ETCM, TCMSP and TargetNet database. Subsequently, the target network model and the major modules were generated by Cytoscape, and the functional enrichment analysis of XFBD targets were completed by DAVID and STRING. As a result, ten of the 13 herbs in XFBD belonged to the lung meridian, and 326 of the 1 224 putative XFBD targets were associated with the disease target of COVID-19, among which 109 targets were enriched in the disease pathways of viral infection and lung injury. The main biological pathways regulated by the key XFBD targets included viral infection, energy metabolism, immunity and inflammation, parasites and bacterial infections. In conclusion, the therapeutic mechanism of XFBD in COVID-19 showed a multi-herb, multi-constituent, multi-target pattern, with lung as the chief targeted organ. By regulating a series of biological pathways closely related to the occurrence and development of diseases, XFBD plays a role in balancing immunity, eliminating inflammation, regulating hepatic and biliary metabolism and recovering energy metabolism balance.

The chemical constituents in Shenmai Injection(SMI) were qualitatively analyzed by using liquid chromatography/quadrupole time-of-flight mass spectrometry(LC-Q-TOF-MS) and liquid chromatography-ion trap-mass spectrometry(LC-IT-MS). The analysis was performed on an Agilent Zorbax SB-C_(18)(4.6 mm×250 mm, 5 μm) and gradient elution was carried out with 0.05% formic acid solution-acetonitrile as mobile phase at a flow rate of 0.6 mL·min~(-1) and a column temperature of 30 ℃. Mass spectrometry data of the components in SMI were collected in negative ion mode. The structures of components were speculated and identified by analyzing mass spectrometry data, comparing with standards, and referring to related literature. A total of 64 components in SMI were estimated, and the structures were confirmed in 16 of them by comparison with standards. Fifty-six compounds derived from Ginseng Radix et Rhizoma Rubra included 34 protopanaxadiol ginsenosides, 19 protopanaxatriol ginsenosides, 1 oleanane ginsenosides and 2 other glycosides. Eight compounds derived from Ophiopogonis Radix included 7 steroidal saponins, and 1 monoterpene glycoside. The results of this study would provide an important theoretical basis for the improvement of the quality control standards and the discovery of effective constituents in SMI.

Testing and analysis of chemical markers is currently the prevailing approach for quality assessment of traditional Chinese medicines. However,several important issues remain to be addressed,including the trade-off between accuracy and coverage. In this study,in order to give full play to the advantages of their respective methods and provide technical support for more comprehensively and rapidly evaluate the quality of Danshen Injection products,a fingerprint method was coupled with quantitative analysis of multicomponents by single marker( QAMS),with Danshen Injection as the carrier. Ultra performance liquid chromatography( UPLC) was used to establish the quantitative fingerprint. The UPLC fingerprints contained 13 common peaks,11 of which were identified by using ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry( UPLC-QTOF-MS). Furthermore,with sodium danshensu as the internal reference substance,relative correction factors( RCFs) of protocatechuic aldehyde,caffeic acid,rosmarinic acid,lithospermic acid,and salvianolic acid B were calculated through slope analysis method,and the QAMS method was adopted to determine the contents of these 6 components. The UPLC fingerprint was employed to assess the consistency of 12 batches of Danshen Injection,which showed good batch-to-batch consistency with similarity higher than 0. 99. In the comparison of contents of the six constituents obtained by QAMS and external standard method( ESM),RSD was all less than 4. 3%,indicating the good accuracy of the QAMS method. The QAMS method developed in this study combined with UPLC fingerprint can comprehensively reflect the internal quality of Danshen Injection when only the reference substance sodium danshensu is consumed,with greatly reduced detection cost and time. It provides a technical basis for further improving the quality standard of Danshen Injection.

Evidence continues to grow on potential health risks associated with Ginkgo biloba and its constituents. While biflavonoid is a subclass of the flavonoid family in Ginkgo biloba with a plenty of pharmacological properties, the potential toxicological effects of biflavonoids remains largely unknown. Thus, the aim of this study was to investigate the in vitro and in vivo toxicological effects of the biflavonoids from Ginkgo biloba (i.e., amentoflavone, sciadopitysin, ginkgetin, isoginkgetin, and bilobetin). In the in vitro cytotoxicity test, the five biflavonoids all reduced cell viability in a dose-dependent manner in human renal tubular epithelial cells (HK-2) and human normal hepatocytes (L-02), indicating they might have potential liver and kidney toxicity. In the in vivo experiments, after intragastrical administration of these biflavonoids at 20 mg·kg·d for 7 days, serum biochemical analysis and histopathological examinations were performed. The activity of alkaline phosphatase was significantly increased after all the biflavonoid administrations and widespread hydropic degeneration of hepatocytes was observed in ginkgetin or bilobetin-treated mice. Moreover, the five biflavonoids all induced acute kidney injury in treated mice and the main pathological lesions were confirmed to the tubule, glomeruli, and interstitium injuries. As the in vitro and in vivo results suggested that these biflavonoids may be more toxic to the kidney than the liver, we further detected the mechanism of biflavonoids-induced nephrotoxicity. The increased TUNEL-positive cells were detected in kidney tissues of biflavonoids-treated mice, accompanied by elevated expression of proapoptotic protein BAX and unchanged levels of antiapoptotic protein BCL-2, indicating apoptosis was involved in biflavonoids-induced nephrotoxicity. Taken together, our results suggested that the five biflavonoids from Ginkgo biloba may have potential hepatic and renal toxicity and more attentions should be paid to ensure Ginkgo biloba preparations safety.

Traditional Chinese medicine (TCM) prescription is the main therapies for disease prevention and treatment in Chinese medicine. Following the guidance of the theory of TCM and developing drug by composing prescriptions of TCM materials and pieces, it is a traditional application mode of TCM, and still widely used in clinic. TCM prescription has theoretical advantages and rich clinical application experience in dealing with multi-factor complex diseases, but scientific research is relatively weak. The lack of scientific cognition of the effective substances and mechanism of Chinese medicine leads to insufficient understanding of the efficacy regularity, which affects the stability of effect and hinders the improvement of quality of Chinese medicinal products. Component-based Chinese medicine (CCM) is an innovation based on inheritance, which breaks through the tradition of experience-based prescription and realize the transformation of compatibility from herbal pieces to components. CCM is an important achievement during the research process of modernization of Chinese medicine. Under the support of three national "973" projects, in order to reveal the scientific connotation of the prescription compatibility theory and develop innovative Chinese drugs, we have launched theoretical innovation and technological innovation around the "two relatively clear", and opened up the research field of CCM. CCM is an innovation based on inheritance, breaking through the tradition of experience based prescription, and realizing the transformation from compatibility of herbal pieces to component compatibility, which is an important achievement of the modernization of traditional Chinese medicine. In the past more than 10 years, with the deepening of research and the expansion of application, the theory and methods of CCM and efficacy-oriented compatibility have been continuously improved. The value of CCM is not only in developing new drug, more important is to build a communication bridge between traditional Chinese medicine and modern science and construct the system of key technologies which meet the need of innovation and development of TCM. This paper focused on the research progress, related concepts and technology development of CCM, as well as its application prospect in the theory research of Chinese medicine, development of innovative Chinese drugs, secondary development of Chinese patent medicine and upgrading of pharmaceutical technology.
ABSTRACT
Screening out the safety-related substances and establishing the corresponding standard has been a key research issue to improve the safety of traditional Chinese medicine injections(TCMIs). 5-HMF which widely exists in sugar-containing TCMIs has long been considered as an important safety-related substance. In this review, we summarizes the research progress on the toxicology of 5-HMF as well as the content and standards of 5-HMF in TCMIs.Therein, both literature summary and analysis results indicate that there are lack of toxicology researches of 5-HMF and its metabolites in TCMIs, although the potential toxicity of 5-HMF and its metabolites has been reported. Moreover, the content of 5-HMF largely varies from TCMIs to TCMIs, and even in the same TCMIs from different factories. To ensure the clinical efficacy of TCMIs, it urgent to carry out the study of the toxicology of 5-HMF in TCMIs comprehensively and systematically, so as to set up a relatively uniform standard as well as to develop process quality control method.
ABSTRACT

Analogous formulae (AF) refer to a set of traditional Chinese medicine (TCM) formulae sharing similar herbs and/or indications. Dissecting functional chemome of analogous formulae could enhance the understanding of the intrinsic nature of TCM. In this study, taking 5 Xiaoqinglong decoction analogous formulae (XQL AF) including Xiaoqinglong decoction, Mahuang Xingren Shigao Gancao decoction, Mahuang Fuzi decoction, Houpu Mahuang decoction and Daqinglong decoction as example, we systematically investigated the relationship between compounds and indications using network formulaology approach. The functional chemome of XQL AF were revealed by network analysis and molecular docking. This successful application in XQL AF suggests network formulaology could be a useful tool for AF-related research and therefore provide a new way to discover the scientific foundation of Zhang Zhongjing's herbal formulae.

Retinal vein occlusion (RVO) is a common clinical disease causing vision loss. Risk factors such as diabetes, atherosclerosis are closely associated with RVO. Xuesaitong injection is used extensively in clinical treatment of RVO, however the mechanism is still unclear. In this study, we investigated the protective effect of Xuesaitong injection on RVO rat model. Using a compound-target network of Xuesaitong on anti-RVO constructed by literature mining, we aim to elucidate the multi-compound, multi-target effect of Xuesaitong injection. Fifteen potential targets of Xuesaitong injection associated with inflammation, angiogenesis, apoptosis, and coagulation were identified in this study. VEGF, IL-1beta and IL-6, three important targets in the compound-target network were further experimentally validated. This study provided experimental evidence for Xuesaitong injection being effective in treating RVO and a network view on its anti-RVO mode of action through a multi-compound and multiple-target mechanism.

It is the objective of this study to optimize the extraction process of red ginseng to minimize the unit cost of extracting effective ingredients. The relation between the target variables of total quantity of ginsenosides and first extraction time, first extraction solution amount, second extraction time, second extract solution amount were studied with Box-Behnken experimental design method. At the same we also considered the cost of extraction solution and energy usage. The objective function was set as unit cost of target (total quantity of ginsenosides or its purity) for the multi-objective optimization of extraction process. As a result, the optimal process parameters were found as first extraction time (108.7 min), first extraction solution amount folds (12), second extraction time (30 min), second extraction solution amount folds (8) to minimize the unit cost. It indicated that this approach could potentially be used to optimize industrial extraction process for manufacturing Chinese medicine.
