ABSTRACT

Yigongsan is derived from Xiaoer Yaozheng Zhijue written by QIAN Yi in the Northern Song dynasty, which is the No. 3 formula in the Catalogue of Ancient Famous Classical Formulas(The Second Batch of Pediatrics) released by the National Administration of Traditional Chinese Medicine(TCM) in September 2022, and it can be developed as a class 3.1 new TCM drug. By referring to ancient medical books and modern literature, this study conducted herbal textual research on Yigongsan from five aspects, including historical evolution, origin and processing, dosage conversion, usage and preparation methods, and functional application, then formed the key information table of this formula, in order to provide reference for the development of reference samples and preparations of Yigongsan. Based on the results of the study, it is recommended that Panax ginseng should be removed the basal part of stem(rhizoma), Poria cocos should be removed the peel, Citrus reticulata should be cut into shreds and Glycyrrhiza uralensis should be used. According to 4.13 g/Qian(钱), 1 g/slice for ginger, 3 g for each jujube and 300 mL/Zhan(盏), the doses of Ginseng Radix, Poria, Atractylodis Macrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Citri Reticulatae Pericarpium, Zingiberis Rhizoma Recens, Jujubae Fructus were 1.652, 1.652, 1.652, 1.652, 1.652, 5, 6 g, and the total amount was 19.26 g. The decocting method was to crush the medicinal materials into fine powder with 50-80 mesh, add 300 mL of water and decoct to 210 mL for each dose, then remove the dregs and take it warmly. This formula was recorded in ancient books as the main treatment for the cold-deficiency of spleen and stomach, and Qi stagnation in children with vomiting and diarrhea and lack of appetite. It has been flexibly applied by later generations of physicians, and is often used to treat anorexia, inflammation of the digestive tract, diarrhea and other diseases in children.

ABSTRACT

Chinese patent medicines(CPMs) are unique therapeutic drugs in China. Establishing and improving the evaluation criteria is an important measure to promote the high-quality development of CPMs. Based on the "evaluation criteria of high-grade CPMs with quality as the core index" established by our group in 2018, the "high-quality evaluation criteria for CPMs based on whole process control" was proposed in the present study in 2022. The scope of application and basic principles of the new criteria were clarified. A quality evaluation scoring table was established in the new criteria, including five parts: raw material selection, production process, quality control, efficacy evaluation, and brand building. The technical evaluation indexes involved have increased from 20% in the original criteria to 70% in the new criteria, and efficacy evaluation has been added in the new criteria. The subjective evaluation indicators account for a large proportion in the original criteria, which is prone to bias. The improved criteria overcome this shortcoming. It is expected that the new criteria as a basis can play a better role in the selection of high-quality products of CPMs, guide enterprises and institutions to participate actively in the evaluation and research of high-quality CPMs, and promote the high-quality development of CPMs.

ABSTRACT

This study aims to establish the ultra-performance liquid chromatography(UPLC) fingerprint and multi-indicator quantitative analysis method for Schisandrae Sphenantherae Fructus(SSF) and to screen out the potential quality markers(Q-markers) of hepatoprotection based on network pharmacology. The similarity analysis was performed using the Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System, which showed that the similarity of the fingerprints of 15 samples from different regions ranged from 0.981 to 0.998. Eighteen common components were identified, from which 3 differential components were selected by cluster analysis and principal component analysis. The "component-target-pathway" network was built to predict the core components related to the hepatoprotective effects. Fourteen core components were screened by network pharmacology. They acted on the targets such as AKT1, CCND1, CYP1A1, CYP3A4, MAPK1, MAPK3, NOS2, NQO1, and PTGS2 to regulate the signaling pathways of lipid metabolism and atherosclerosis, hepatitis B, interleukin-17, and tumor necrosis factor. Considering the chemical measurability, characteristics, and validity, schisantherin A, anwulignan, and schisandrin A were identified as the Q-markers. The content of schisantherin A, anwulignan, and schisandrin A in the test samples were 0.20%-0.57%, 0.13%-0.33%, and 0.42%-0.70%, respectively. Combining the fingerprint, network pharmacology, and content determination, this study predicted that schisantherin A, anwulignan, and schisandrin A were the Q-markers for the hepatoprotective effect of SSF. The results can provide reference for improving the quality evaluation standard and exploring the hepatoprotective mechanism of SSF.

ABSTRACT

High quality is the premise for the implementation of high quality and good price for decoction pieces, and grade is the most direct manifestation of high quality of decoction pieces. However, there is still a lack of scientific and reasonable methods for evaluating the grade of decoction pieces, and it is urgent to establish a widely recognized and unified standard for the grade of decoction pieces to ensure the quality of the decoction pieces and guarantee the safety and efficacy of clinical use. Based on this, this paper focused on analyzing the problems of the current grade evaluation methods, such as unclear distinction between quality standards and grade standards, unreasonable selection of grade evaluation indicators, and inaccurate application of mathematical statistical methods. Based on the analysis of the grade evaluation of decoction pieces, this paper proposed four criteria for establishing the grade evaluation method of decoction pieces, namely universality, comprehensiveness, reliability and convenience, in order to establish a more reasonable and unified grade standard for decoction pieces and promote the quality improvement of decoction pieces and the development of the industry.

ABSTRACT

Chinese herbal piece is an important component of the traditional Chinese medicine (TCM) system, and identifying their quality and grading can promote the development and utilization of Chinese herbal pieces. Utilizing deep learning for intelligent identification of Chinese herbal pieces can save time, effort, and cost, while also reasonably avoiding the constraints of human subjectivity, providing a guarantee for efficient identification of Chinese herbal pieces. In this study, a dataset containing 108 kinds of Chinese herbal pieces (14 058 images) was constructed,the basic YOLOv4 algorithm was employed to identify the 108 kinds of Chinese herbal pieces of our database The mean average precision (mAP) of the developed basic YOLOv4 model reached 85.3%. In addition, the receptive field block was introduced into the neck network of YOLOv4 algorithm, and the improved YOLOv4 algorithm was used to identify Chinese herbal pieces. The mAPof the improved YOLOv4 model achieved 88.7%, the average precision of 80 kinds of decoction pieces exceeded 80%, the average precision of 48 kinds of decoction pieces exceeded 90%. These results indicate that adding the receptive field module can help to some extent in the identification of Chinese herbal medicine pieces with different sizes and small volumes. Finally, the average precision of each kind of Chinese herbal medicine piece by the improved YOLOv4 model was further analyzed. Through in-depth analysis of the original images of Chinese herbal medicine pieces with low prediction average precision, it was clarified that the quantity and quality of original images of Chinese herbal medicine pieces are key to performing intelligent object detection. The improved YOLOv4 model constructed in this study can be used for the rapid identification of Chinese herbal pieces, and also provide reference guidance for the manual authentication of Chinese herbal medicine decoction pieces.

ABSTRACT

Jianwei Xiaoshi tablets, as a common variety of Chinese patent medicine with "one product with many manufacturers", have many manufacturers and huge market sales. However, the phenomenon about uneven quality and discrepant price is prominent. Based on this, this study was carried out for the quality evaluation of Jianwei Xiaoshi tablets by applying the high-quality evaluation criteria with the quality as core for Chinese patent medicine, which was based on the full production cycle, from the multi-dimension including raw material selection, production process, quality control, post-marketing research and so on. The evaluation results showed that the quality evaluation scores of Jianwei Xiaoshi tablets from different manufacturers varied greatly (ranging from 35 to 66), indicating that the quality was significantly different. In the actual production, generally inadequate attention was paid to the quality of raw materials, and the quality of raw materials was insufficient with the score ratio of 43%, especially the poor consistency control of them. The role of good manufacturing practice was obvious, and the scores of production process were generally high with the average score ratio of 62%, and the maximum up to 80%. The technological advancement of the manufacturer was outstanding. The score ratio of quality control was only 31% that the internal quality standard of each manufacture almost stayed at the qualified line, which was equal to the national standard, and the consistency of products was insufficient. The post-marketing research was lacking with the score ratio of 37%. Manufacturers with high brand awareness and market share were upper scores, while the others lagged far behind. The results of this evaluation are in line with the overall prediction, which can provide a reference for the high-quality evaluation of Chinese patent medicine, and supply the scientific data for high-quality and high-price application.

ABSTRACT

"Omics" and bioinformatics have brought new ideas to the study of traditional Chinese medicine. This study used metabonomics and network pharmacology to investigate the pharmacodynamic basis and regulation of Qishen Yiqi dropping pill (QDP) improving cardiac energy metabolism in rats with heart failure (HF). 1H NMR metabonomics analysis showed that eight metabolites, including carnitine, glutamine, creatine, proline, homocitrulline, lactic acid, taurine and alanine appeared significant callback after QDP treatment for HF. The results indicate that QDP regulates the metabolism of carbohydrate, lipid, ATP and protein. The animal experiment was conducted in accordance with the regulations of the Ethics Committee for Experimental Animal Management and Animal Welfare of Institute of Materia Medica, Chinese Academy of Medical Sciences. A "drug-component-target-disease" network was established using network pharmacology, and the "component-target" sub-network related to the above energy metabolism processes was extracted by combining metabonomics results. Results revealed 79 chemical compounds and 47 potential targets of QDP involved in the regulation of energy metabolism, and identified key chemical components including ursolic acid, notoginsenoside G, ginsenoside-Rh1, and core targets such as INS, PPARG, and AKT1. The results also demonstrated the complex multi-target and multi-component relationship between QDP and HF from the perspective of energy metabolism. The molecular docking technique verified a strong interaction between some targets and chemical compounds, with affinities less than -5 kcal·mol-1. The results of this study provide useful information for the clinical application, development, and utilization of QDP.

ABSTRACT

Studies have found that metformin is not only the preferred drug for lowering blood sugar, but also shows lipid-lowering and weight-loss effects. The purpose of this study was to use a hyperlipidemia hamster model to investigate the lipid-lowering effect of metformin and its effect on important metabolic pathways in lipid metabolism disorders. Fifty golden hamsters were divided into a control group, a model group, metformin high- and low-dose groups, and a simvastatin group. A high-fat diet was fed for 1 week to create the model, and then drug was administered for 11 weeks with the high-fat diet. Serum was taken for measurement of blood lipid and blood glucose at 2, 6, and 9 weeks after administration, and at weeks 3, 5, and 9 feces and urine were collected for 1H NMR metabolomics tests. After 11 weeks of intravenous injection of [U-13C6] glucose, serum was collected for a 13C NMR metabolic flux test. The results showed that the administration of metformin can significantly reduce blood lipids and glucose levels and can significantly affect metabolic pathways such as sugar metabolism, lipid metabolism, ketone metabolism, amino acid metabolism, and intestinal flora metabolism. The results of the metabolic flux analysis showed that the high-fat diet reduced the metabolism of tricarboxylic acids by 37.48%. After administration of low and high doses of metformin the metabolism of tricarboxylic acid increased by 98.14% and 143.10%, respectively. After administration of simvastatin tricarboxylic acid metabolism increased by 33.18%. The results indicate that metformin has a significant effect on promoting energy metabolism. This study used a combination of metabolomics and metabolic flow to explore the effect of metformin on lipid metabolism disorders and quantifies changes in the key pathway of energy metabolism-the tricarboxylic acid cycle. This study provides useful information for the study of the efficacy and mechanism of metformin, as well as a practical technical method for the screening of lipid-lowering drugs based on a hamster model.

ABSTRACT

Objective: To explore the mechanism of herbal cake-partitioned moxibustion in Crohn disease (CD) treatment by observing the effect of herbal cake-partitioned moxibustion on protein expressions of colonic M2 macrophage marker CD206, AMP-activated protein kinase (AMPK) and tuberous sclerosis complex (TSC) 2. Methods: Twenty-six specific pathogen free male rats were randomly divided into a normal group, a model group and a herbal cake-partitioned moxibustion group. The CD model was prepared by enema with the mixture of 5% (W/V) 2,4,6- trinitrobenzene sulfonic acid (TNBS) and 50% ethanol at 2:1 (volume ratio). After the model was successfully prepared, rats in the herbal cake-partitioned moxibustion group received herbal cake-partitioned moxibustion at Qihai (CV 6) and bilateral Tianshu (ST 25). Hematoxylin-eosin (HE) staining was used to observe the histopathological changes of rat colon; immunohistochemical technique was used to detect the expression of colonic CD206 protein; Western blot, immunofluorescence, and real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) technologies were used to detect the protein and mRNA expressions of colonic AMPK and TSC2. Results: Compared with the normal group, rats in the model group showed damaged colonic mucosa, missing of the epithelial layer, thickened submucosa, vascular proliferation, massive infiltration of monocytes and lymphocytes, and cracked ulcers that reached the muscle layer. Rats in the herbal cake-partitioned moxibustion group showed reduced intestinal inflammation and healing intestinal epithelium ulcers. Compared with the normal group, rat colonic CD206 protein expression, and the protein and mRNA expressions of colonic AMPK and TSC2 were decreased in the model group (all P<0.01); compared with the model group, rat colonic CD206 protein expression was increased (P<0.01), as well as the protein and mRNA expressions of AMPK and TSC2 in the herbal cake-partitioned moxibustion (all P<0.05). Conclusion: Herbal cake-partitioned moxibustion can reduce intestinal inflammation in CD rats, increase colonic CD206 protein expression, and up-regulate the protein and mRNA expressions of colonic AMPK and TSC2.

ABSTRACT

Psychiatric diseases represented by depression have gradually become one of the major health problems of people in the fast-paced, high-pressure society. Severe cases can cause suicides, huge harm or disaster to families and the society. Although modern medicine has made great progress in the field of anti-depressant drug therapy, depression still cannot be cured. At the same time, traditional Chinese medicines(TCM) with a definite curative effect, few adverse reactions, and mild efficacy have received increasing attention. TCM valerianae Jatanmansi Rhizoma et Radix has been widely used to alleviate sleep disorder, and its root extract is popularly known as valerian and used as a mild sedative for a long time in European. Tagara takes Valerianae Jatamansi Rhizoma et Radix as the key ingredient for treatment of depression-type insomnia, and is available abroad. It is reported that iridoid, sesquiterpenes, flavonoids or extract from Valerianae Jatamansi Rhizoma et Radix has a superior anti-depression activity in both animal and clinical trials, and the mechanism is mainly related to the regulation of neurotransmitters in the brain, the improvement of the function of the hypothalamic-pituitary-adrenal (HPA) axis, the resistance of free radicals and inflammation, and the neuroprotective effect. However, there is still lack of report on the anti-depression system and in-depth research of Valerianae Jatamansi Rhizoma et Radix. Therefore, it is urgently necessary to systematically collect and summarize the anti-depressant activity and explain the relevant mechanisms, so as to provide reference for the further development of Valerianae Jatamansi Rhizoma et Radix medicinal resources.

ABSTRACT

Grade evaluation method of quality constant is a kind of grading method for Chinese medicinal materials and decoction pieces,combining the external morphological index and internal content index. This method was used in this paper for grade evaluation of Gardeniae Fructus. By measuring the morphological and content indexes of 14 batches of Gardeniae Fructus,a method for calculating the quality constant of fruits was established,and the grade evaluation criteria were formed. At the same time,the NO inhibition effect of different grades of Gardeniae Fructus samples on RAW264. 7 cells induced by LPS was determined to investigate the relationship between the quality grade and pharmacodynamics of decoction pieces. The results showed that the quality constants of Gardeniae Fructus decoction piece samples ranged from 1. 46 to 4. 42. If the percentage quality constant ≥80% was classified into first-class,50%-80%as second-class and the rest as third-class,the quality constant was ≥3. 54 for first-class,2. 21-3. 54 for second-class and <2. 21 for third-class Gardeniae Fructus decoction pieces. The pharmacodynamic results showed that the pharmacodynamic intensity was positively correlated with the grade,which also proved the rationality of the grade evaluation method of quality constant.
