Immune-inflammatory modulation by natural products derived from edible and medicinal herbs used in Chinese classical prescriptions.

BACKGROUND: Edible and medicinal herbs1 (EMHs) refer to a class of substances with dual attribution of food and medicine. These substances are traditionally used as food and also listed in many international pharmacopoeias, including the European Pharmacopoeia, the United States Pharmacopoeia, and the Chinese Pharmacopoeia. Some classical formulas that are widely used in traditional Chinese medicine include a series of EMHs, which have been shown to be effective with obvious characteristics and advantages. Notably, these EMHs and Chinese classical prescriptions2 (CCPs) have also attracted attention in international herbal medicine research because of their low toxicity and high efficiency as well as the rich body of experience for their long-term clinical use. PURPOSE: Our purpose is to explore the potential therapeutic effect of EMHs with immune-inflammatory modulation for the study of modern cancer drugs. STUDY DESIGN: In the present study, we present a detailed account of some EMHs used in CCPs that have shown considerable research potential in studies exploring modern drugs with immune-inflammatory modulation. METHODS: Approximately 500 publications in the past 30 years were collected from PubMed, Web of Science and ScienceDirect using the keywords, such as natural products, edible and medicinal herbs, Chinese medicine, classical prescription, immune-inflammatory, tumor microenvironment and some related synonyms. The active ingredients instead of herbal extracts or botanical mixtures were focused on and the research conducted over the past decade were discussed emphatically and analyzed comprehensively. RESULTS: More than ten natural products derived from EMHs used in CCPs are discussed and their immune-inflammatory modulation activities, including enhancing antitumor immunity, regulating inflammatory signaling pathways, lowering the proportion of immunosuppressive cells, inhibiting the secretion of proinflammatory cytokines, immunosuppressive factors, and inflammatory mediators, are summarized. CONCLUSION: Our findings demonstrate the immune-inflammatory modulating role of those EMHs used in CCPs and provide new ideas for cancer treatment in clinical settings.

A Chinese classical prescription Maimendong decoction in treatment of pulmonary fibrosis: an overview.

Pulmonary fibrosis (PF) is a chronic and progressive disease characterized by fibrosis and interstitial pneumonia. It has similar clinical symptoms to "Fei Bi" and "Fei Wei" as described in the traditional Chinese medicine (TCM) classic Jingui Yaolue written by Zhang Zhongjing in the Han Dynasty. This study explored the potential of Maimendong Decoction (MMDD). MMDD consists of Ophiopogon japonicus (L.f) (ophiopogonis), Pinellia ternata (Thunb.) Breit. (pinellia), Panax ginseng C. A. Mey. (ginseng), Glycyrrhiza uralensis Fisch. (glycyrrhiza), Zizi phus jujuba Mill. (jujuba), and Oryza sativa L. (oryza sativa), with the function of nourishing the lung and stomach, and reducing the effect of reverse qi. It has been used clinically for over two thousand years to treat conditions like "Fei Bi" and "Fei Wei". Previous research suggests that MMDD and its individual herbal extracts have anti-fibrotic effects. The main focus of MMDD in treating PF is to reduce inflammatory cytokines, inhibit pro-fibrotic factors and oxidative stress, promote differentiation and homing of bone marrow mesenchymal stem cells, and enhance cell autophagy activity. This review summarized the clinical applications, mechanisms, and pharmacological effects of MMDD in treating PF based on existing clinical applications and experimental research. It also discussed current issues and prospects, aiming to provide a reference for further research on the mechanism of PF, drug development, and clinical trials.

Classical prescription Floris Sophorae Powder treat colorectal cancer by regulating KRAS/MEK-ERK signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Colorectal cancer (CRC) belongs to the category of intestinal wind, anal ulcer, abdominal mass and other diseases in traditional Chinese medicine (TCM). Floris Sophorae Powder (F.S), is a classical prescription is recorded in Puji Benshi Fang for the treatment of intestinal carbuncle. It has been incorporated into the prescriptions for the treatment of intestinal diseases and achieved remarkable results in modern medicine. However, the mechanism of F.S in the treatment of colorectal cancer remains unclear and requires further study. AIM OF THE STUDY: To investigate F.S in treating CRC and clarify the underlying mechanism. MATERIALS AND METHODS: This study was based on Dextran Sulfate Sodium Salt (DSS) combined with Azoxymethane (AOM) induced CRC mouse model to clarify the pharmacological effects of F.S. The serum metabolomics was used to study the mechanism of action, and the chemical composition of F.S was found by UPLC-Q-TOF-MS. The rationality of serm metabolomics results was verified through the clinical target database of network pharmacology, and the upstream and downstream targets of related pathways were found. The mechanism pathway was verified by Western blot to clarify its mechanism of action. RESULTS: In vivo pharmacological experiments showed that F.S inhibited tumor growth and improved hematochezia. The vital signs of mice in the high-dose F.S group approached to those in the control group. A total of 43 differential metabolites were found to be significantly changed by serum metabolomics. F.S could modulate and recover most of the differential metabolites, which proved to be closely related to the KRAS/MEK-ERK signaling pathway. A total of 46 compounds in F.S were identified, and the rationality of serm metabolic pathway was verified by network pharmacology. Western blot results also verified that the expression of KRAS, E2F1, p-MEK and p-ERK were significantly decreased after F.S treatment. CONCLUSION: Classical prescription Floris Sophorae Powder treat colorectal cancer by regulating KRAS/MEK-ERK signaling pathway.

Safety assessment of Wuzhuyu decoction extract: acute and subacute oral toxicity studies in rats.

Wuzhuyu decoction (WZYD) is a well-known classic traditional Chinese medicine prescription and has been widely used to treat headache, nausea, vomiting, insomnia, etc. However, little published information is available about its safety. Our aim was to investigate the acute and subacute oral toxicity of WZYD extract in rats following the technical guidelines from China's National Medical Products Administration (NMPA) for single and repeated doses toxicity studies of drugs. Acute oral toxicity was assessed in rats via oral administration of WZYD extract at 4 g/kg three times within a day followed by a 14-day observation period. To evaluate the subacute toxicity, rats were orally administered with WZYD extract at doses of 0, 0.44, 1.33, and 4 g/kg for 28 days. The items examined included clinical signs, body weight, food consumption, hematological and biochemical parameters, bone marrow smear, organ index, and histopathology. After the rats were administered with 12 g/kg (3 × 4 g/kg) WZYD extract, no mortality and toxic effects were observed during the observation period. In the subacute toxicity study, WZYD extract did not cause any significant treatment-related abnormality in each examined item of rats, so the no observed adverse effect level (NOAEL) of WZYD extract for 28 days orally administered to rats is considered to be 4 g/kg, which is approximately 80-fold of its clinical proposed dosage.

Yigongsan， derived from QIAN Yi’s Key to Therapeutics of Children’s Diseases in the Song Dynasty， is a classic pediatric prescription that is included in the Catalogue of Ancient Classic Prescriptions （the Second Batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine in 2022. This paper verifies and analyzes the historical origin， composition， dosage， processing， decoction method and efficacy of Yigongsan by systematically combing ancient books and modern documents. As a result， Yigongsan is composed of five herbs： Panax ginseng， Poria cocos， Atractylodes macrocephala， Citrus reticulata and Glycyrrhiza uralensis， of which P. cocos should be peeled， A. macrocephala is fried with soil， G. uralensis is roasted with honey while P. ginseng and C. reticulata are raw products. According to the dosage of ancient and modern times， each medicinal herb must be ground into fine powder， 1.6 g for each， added with 300 mL of water， 5 pieces of Zingiber officinale， and 2 Ziziphus jujuba， decocted together to 210 mL， and taken before meals. In ancient books， Yigongsan is used to treat vomiting， diarrhea， spleen and stomach deficiency， chest and abdominal distension， and lack of appetite， etc. Modern research showed that Yigongsan could also be used in the diseases of immune system， respiratory system， blood system， etc.， involving infantile anorexia， asthma， anemia， tumors and so on.

Treatment of Chronic Gastritis with Traditional Chinese Medicine: Pharmacological Activities and Mechanisms.

Chronic gastritis (CG) is a common clinical digestive system disease, which is not easyily cured and is prone to recurrence. Traditional Chinese medicine (TCM) plays a significant role in the treatment of CG and has attracted increasing attention for clinical applications. In recent years, a large number of reports have shown that TCM has good therapeutic effect on CG. The aim of this paper is to investigate the pharmacological activities and mechanism of action of TCM in the treatment of CAG. Therefore, by searching the databases of Pubmed, China National Knowledge Infrastructure, Wanfang, and Baidu academic databases, this paper has summarized the molecular mechanisms of TCM in improving CG. The results show that the improvement of GC by TCM is closely related to a variety of molecular mechanisms, including the inhibition of Helicobacter pylori (Hp) infection, alleviation of oxidative stress, improvement of gastric function, repair of gastric mucosa, inhibition of inflammatory response, and apoptosis. More importantly, IRF8-IFN-γ, IL-4-STAT6, Hedgehog, pERK1/2, MAPK, PI3K-Akt, NF-κB, TNFR-c-Src-ERK1/2-c-Fos, Nrf2/HO-1, and HIF-1α/VEGF signaling pathways are considered as important molecular targets for TCM in the treatment of GC. These important findings will provide a direction and a basis for further exploring the pathogenesis of GC and tapping the potential of TCM in clinical treatment. This review also puts forward a bright prospect for future research of TCM in the treatment of CG.

Clinical Application Analysis of Da Qinjiaotang Based on Ancient and Modern Literature / 中国实验方剂学杂志

Da Qinjiaotang is a common classical prescription for the treatment of stroke. It originates from Collection of Writings on the Mechanism of Disease， Suitability of Qi， and the Safeguarding of Life as Discussed in the Basic Questions （《素问病机气宜保命集》） by physician LIU Wansu， and is composed of Gentianae Macrophyllae Radix， Glycyrrhizae Radix et Rhizoma， Chuanxiong Rhizoma， Angelicae Sinensis Radix， Paeoniae Radix Alba， Asari Radix et Rhizoma， Notopterygii Rhizoma et Radix， Saposhnikoviae Radix， Scutellariae Radix， Gypsum Fibrosum， Angelicae Dahuricae Radix， Atractylodis Macrocephalae Rhizoma， Rehmanniae Radix， Rehmanniae Radix Praeparata， Poria， and Angelicae Pubescentis Radix. Doctors of all dynasties have disputed the composition principle of the prescription and argued whether its treatment of stroke belongs to the theory of "internal wind" or "external wind". Through collating and analyzing ancient and modern literature related to the indications of Da Qinjiaotang， this paper was dedicated to the origin of syndrome differentiation and treatment of Da Qinjiaotang. According to LIU Wansu's original works， Da Qinjiaotang is a prescription for the treatment of "internal wind"， and in the prescription， wind medicinal herbs such as Gentianae Macrophyllae Radix， Notopterygii Rhizoma et Radix and Angelicae Pubescentis Radix removes stagnation， clears sweat pore， and makes qi and blood channels flow smoothly. However， later generations， affected by the idea of "external wind"， believe that this prescription is used for the treatment of "external wind". Ancient physicians gradually supplemented the symptoms of stroke， such as wry eye and mouth， hemibody pain and limb numbness， which were treated by Da Qinjiaotang， and Da Qinjiaotang was also applied to the treatment of other diseases， such as tendon dryness， convulsion and arthralgia. Modern doctors still explain the disease pathogenesis from the theory of "external wind" as deficiency in channels and collaterals and the entry of pathogenic wind， and the prescription has the effect of dispersing wind， clearing heat and nourishing and activating blood. In clinical practice， Da Qinjiaotang is mainly used to treat cerebrovascular diseases and peripheral facial paralysis in nervous system diseases， gouty arthritis and rheumatic arthritis in the rheumatic immune system and skin diseases. The above findings facilitate the research and development of Da Qinjiaotang.

Zhishi Xiebai Guizhi Tang， derived from Synopsis of the Golden Chamber （《金匮要略》， Han dynasty， ZHANG Zhongjing）， is a famous classical prescription commonly used for chest impediment. By means of bibliometrics， the authors collected 63 ancient Chinese medical books related to Zhishi Xiebai Guizhi Tang and screened 36 effective books for statistical analysis of the historical origin， composition， main indications， dosage， processing， decocting method and other aspects of the prescription. The findings revealed that Zhishi Xiebai Guizhi Tang was composed of five medicinal herbs， namely， Aurantii Fructus Immaturus， Allii Macrostemonis Bulbus， Cinnamomi Ramulus， Magnoliae Officinalis Cortex， and Trichosanthis Fructus， with the function of activating Yang， dissipating mass， dispelling phlegm and lowering Qi. The prescription was mainly used to treat chest impediment， chest fullness， chest pain， wheezing， coughing and shortness of breath caused by suppressed Yang Qi， stagnant heart Qi， stagnant phlegm and stasis， and phlegm evil blocking heart， chest or lungs. Additionally， it was found that there were 70 modern literature recording the clinical applications of Zhishi Xiebai Guizhi Tang， and the main system diseases treated were circulatory system （51， 72.85%）， endocrine system （4， 5.7%）， respiratory system （9， 12.85%） and digestive system （6， 8.57%）， of which circulatory system is dominated by coronary heart disease （chest impediment in traditional Chinese medicine）. The involved medical syndrome types mainly included internal obstruction of phlegm heat and turbidity， obstruction of phlegm turbidity and stasis， congealing cold， phlegm， stasis and Qi stagnation， chest Yang depression and combined phlegm and stasis. Ancient medical records and modern clinical application are the keys to ensure the safety and effectiveness of famous classical prescriptions and compound preparations. Therefore， this paper sorted and mined ancient medical books of Zhishi Xiebai Guizhi Tang and statistically analyzed its modern clinical application， aiming to provide a literature reference for the research and development of new drugs and clinical application of the prescription.

Analysis of Classical Prescription Baizhusan Based on Ancient Literature / 中国实验方剂学杂志

Baizhusan， derived from Key to Medicines and Patterns of Children's Diseases （《小儿药证直诀》） by QIAN Yi in Song dynasty， is a classical prescription that has been highly praised by doctors and widely used in clinical practice. It was included in the Catalogue of Ancient Classical Prescriptions （the second batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine （TCM） in 2022. In this paper， the ancient documents related to Baizhusan were collected by bibliographical research， and the source， composition， herb origin and processing， dosage， decocting method， administration method， functions and indications of the prescription were analyzed and verified. A total of 211 ancient documents on Baizhusan were obtained， involving 116 ancient TCM books. It was found that there were many prescriptions named Baizhusan in ancient times， but the prescription named Baizhusan and composed of Ginseng Radix et Rhizoma， Poria， Atractylodis Macrocephalae Rhizoma， Pogostemonis Herba， Aucklandiae Radix， Glycyrrhizae Radix et Rhizoma， and Puerariae Lobatae Radix was first seen in Key to Medicines and Patterns of Children's Diseases， and is now generally known as Qiweibaizhusan. The composition and functions of Baizhusan were unified in past dynasties， and its herb origin and processing were basically clear. However， there was a dispute on the processing of Atractylodis Macrocephalae Rhizoma and Glycyrrhizae Radix et Rhizoma， which was solved by recommended use of soil-fried Atractylodis Macrocephalae Rhizoma and raw Glycyrrhizae Radix et Rhizoma. Boasting the functions of tonifying spleen， replenishing Qi， harmonizing stomach and promoting fluid production， Baizhusan treated a variety of symptoms such as diarrhea， consumptive thirst and loss of appetite， which were consistent in ancient and modern literature， but attention should be attached to the basic pathogenesis of spleen deficiency and fluid inadequacy. In addition， considerable disagreements were also observed about the dosage and decocting method of Baizhusan in the documents， and the combination ratio of Baizhusan in another version of Key to Medicines and Patterns of Children's Diseases of Wuyingdian Zhenben was the dominant standard for drug use in past dynasties.

[Review of classical prescriptions in treatment of ulcerative colitis].

Ulcerative colitis(UC) is a continuous inflammatory bowel disease with the main clinical manifestations of abdominal pain, diarrhea, and mucous bloody stools, mainly attacking the colorectal mucosa and submucosa. It is characterized by high recurrence rate, difficult cure, and clustering and regional occurrence. Chinese medicinal prescriptions for the treatment of UC have good therapeutic effect, multi-target regulation, slight toxicity, and no obvious side effects. In particular, the classical prescriptions highlight the characteristics and advantages of traditional Chinese medicine theory and have attracted much attention in recent years. To enable researchers to timely and comprehensively understand the classical prescriptions in the treatment of UC, we reviewed the studies about the pharmacodynamic material basis, quality control, action mechanism, and clinical application of relevant classical prescriptions. We first introduced the latest research progress in the active components such as alkaloids, polysaccharides, saponins, and flavonoids in relevant classical prescriptions. Then, we reviewed the latest research achievements on the quality control of classical prescriptions for the treatment of UC by gas chromatography, liquid chromatography, mass spectrometry, liquid chromatography-mass spectrometry and the like. Further, we summarized the research advances in the mechanisms of relevant prescriptions in the treatment of UC based on network pharmacology, molecular docking, integrated pharmacology platform, and animal experiments. Finally, we generalized the clinical application of the classical prescriptions for clearing heat and removing dampness, mildly regulating cold and heat, soothing liver and regulating spleen, strengthening spleen and invigorating Qi, and tonifying spleen and stomach. By systematic summary of the research progress in relevant classical prescriptions, we hope to promote the application and development of such prescriptions in UC treatment.

Mechanism of tonifying-kidney Chinese herbal medicine in the treatment of chronic heart failure.

According to traditional Chinese medicine (TCM), chronic heart failure has the basic pathological characteristics of "heart-kidney yang deficiency." Chronic heart failure with heart- and kidney-Yang deficiency has good overlap with New York Heart Association (NYHA) classes III and IV. Traditional Chinese medicine classical prescriptions for the treatment of chronic heart failure often take "warming and tonifying kidney-Yang" as the core, supplemented by herbal compositions with functions of "promoting blood circulation and dispersing blood stasis." Nowadays, there are still many classical and folk prescriptions for chronic heart failure treatment, such as Zhenwu decoction, Bushen Huoxue decoction, Shenfu decoction, Sini decoction, as well as Qili Qiangxin capsule. This review focuses on classical formulations and their active constituents that play a key role in preventing chronic heart failure by suppressing inflammation and modulating immune and neurohumoral factors. In addition, given that mitochondrial metabolic reprogramming has intimate relation with inflammation, cardiac hypertrophy, and fibrosis, the regulatory role of classical prescriptions and their active components in metabolic reprogramming, including glycolysis and lipid ß-oxidation, is also presented. Although the exact mechanism is unknown, the classical TCM prescriptions still have good clinical effects in treating chronic heart failure. This review will provide a modern pharmacological explanation for its mechanism and offer evidence for clinical medication by combining TCM syndrome differentiation with chronic heart failure clinical stages.

[Mechanism of Qingwei Powder in treatment of periodontitis based on UPLC-Q-TOF-MS, GC-MS, network pharmacology and molecular docking].

The present study explored the mechanism of Qingwei Powder(QP) in the treatment of periodontitis based on chromatography-mass spectrometry and network pharmacology-molecular docking techniques. UPLC-Q-TOF-MS and GC-MS were used to identify the chemical constituents of QP. The active components and targets were screened out through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and their targets were predicted using SwissTargetPrediction. Targets related to periodontitis were obtained from GeneCards, OMIM, and DisGeNET. Venn diagram was constructed using Venny 2.1 to obtain the intersection targets. Cytoscape 3.7.2 was used to construct the "chemical component-target-disease" network. The targets were analyzed for Gene Ontology(GO) function and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment by clusterProfiler R, and the "chemical component-target-pathway" network was constructed. The binding activity of the active components to the target proteins was verified by molecular docking. A total of 189 chemical components were obtained by UPLC-Q-TOF-MS and GC-MS, including 39 active components with 180 potential targets related to periodontitis. Target enrichment analysis of the active components yielded 92 KEGG pathways. Twenty KEGG pathways, 34 active components, and 99 targets were involved in the "chemical component-target-pathway" network. Molecular docking verified a good binding ability of the key targets to the key compounds. This study preliminarily indicates that QP is effective in treating periodontitis through multiple components, multiple targets, and multiple pathways, which reflects the complex system of Chinese medicine. This study provides the theoretical foundation for the subsequent research on the material basis and key quality attributes of QP.

[Quality value transfer of material benchmark of Guizhi Jia Gegen Decoction].

A total of 15 batches of the substance reference of Guizhi Jia Gegen Decoction(GZGGD) were prepared and the characteristic fingerprints of them were established. Furthermore, the similarity of the fingerprints and peak attributes were explored. The extraction rate, and the content and the transfer rate ranges of the index components, puerarin, paeoniflorin, liquiritin, and ammonium glycyrrhizate were determined for the analysis of the quality value transfer. The result demonstrated that the fingerprints of the 15 batches of the samples showed high similarity(>0.99). A total of 15 characteristic peaks were identified from the fingerprints, with 10 for Puerariae Lobatae Radix, 1 for Cinnamomi Ramulus, 2 for Paeoniae Radix Alba, and 2 for Glycyrrhizae Radix et Rhizoma. The content of puerarin was 11.05-18.35 mg·g~(-1) and the average transfer rate was 21.27%-39.49%. The corresponding figures were 7.95-10.90 mg·g~(-1) and 23.28%-43.23% for paeoniflorin, 3.25-4.95 mg·g~(-1) and 32.31%-61.27% for ammonium glycyrrhizate, and 3.65-5.80 mg·g~(-1) and 14.57%-27.05% for liquiritin. The extraction rate of the 15 batches of samples was in the range of 16.85%-21.78%. In this paper, the quality value transfer of the substance reference of GZGGD was analyzed based on characteristic fingerprint, content of index components, and the extraction rate. This study is expected to lay a basis for the quality control and further development of GZGGD.
