A Mini Review of the Literature with a Special Focus on India on the Prevalence of Indian Traditional Medicine (ITM) use During Pregnancy

Background: Although pregnancy has been an integral part of women’s lives for millennia, not all women have found the process comfortable. About 65 percent of women in India consume Indian traditional herbs during pregnancy. Herbal medicines are used nowadays by up to half of the world's population. Phytomedicines isolated from plants contain a wide variety of bioactive components that can have both negative and positive effects. Many herbal plants, such as Sage (Salvia fruticosa), golden cotula (Matricaria aurea), anise (P. anisum), peppermint (Mentha aquatica), and cumin (Cuminum cyminum), etc., are used in pregnancy. To minimize the adverse effects, the use of Indian traditional medicine can be the best possible alternative. Objective: Regarding the usage of herbal medicines in India, there are large research gaps and a lack of a regulatory framework. This article aims to highlight the most common traditional Indian remedies used by pregnant women, along with their uses and any possible interactions between herbal remedies and prescription drugs. Method: Several databases, including the WHO guidelines, PubMed, Bentham Science, Elsevier, Springer Nature, Wiley, and Research Gate, were used to compile the data for the article following a thorough analysis of the various research findings connected to pregnancy and herbs for pregnancy care. Result: An overview of the use of herbal medicine is given in this review, along with information on its limitations and general safety. The prevalence of herbal medicine use during pregnancy in India is then discussed, along with the uses, adverse effects, side effects, and efficacy of the most popular herbal medications. Conclusion: The use of herbal medicine during pregnancy is a common phenomenon. The outcomes of this study showed Indian Traditional medicines are known to have numerous advantages that can be helpful during or after pregnancy, including raising milk production, reducing nausea, easing labor pains, reducing morning sickness, or reducing flatulence, however, some herbal remedies have the potential to be teratogenic, poisonous, and abortive, especially during the first trimester of pregnancy because the active components of some medicinal plants can cross the placental barrier and get to the foetus. To determine the safety of taking herbal medications, studies, especially clinical trial trials, must be conducted.

Synergistic appetite-enhancing effects of essential oils isolated from blended spices

ABSTRACT Chemical and bioactive analyses of spice oils have been widely performed. However, spice blends such as curry powder are not prescribed as herbal medicine, so their bioactivities have not been sufficiently explored. Here, cinnamon, fennel, and clove were blended following the CH1 herbal medicine prescription, and, in mice, appetite-enhancing effects were compared between the blended and individual spices. GC and GC/MS analyses revealed the following major components of the CH1 blended spice oil: trans-anethole, trans-cinnamaldehyde, and eugenol. Food intake was observed in 4 h feeding tests after 16 h of fasting. Eugenol and trans-anethole lowered the dose for the appetite-enhancing effects of trans-cinnamaldehyde 10-fold. After 1 week of daily administration, the dose-lowering effect of eugenol disappeared and the appetite-enhancing effects of trans-cinnamaldehyde occurred at a higher dose. Although the dose-lowering effect of trans-anethole decreased, food intake was still increased significantly by daily administration of blended spices at the lower dose.

PrescDRL: deep reinforcement learning for herbal prescription planning in treatment of chronic diseases

Treatment planning for chronic diseases is a critical task in medical artificial intelligence, particularly in traditional Chinese medicine (TCM). However, generating optimized sequential treatment strategies for patients with chronic diseases in different clinical encounters remains a challenging issue that requires further exploration. In this study, we proposed a TCM herbal prescription planning framework based on deep reinforcement learning for chronic disease treatment (PrescDRL). PrescDRL is a sequential herbal prescription optimization model that focuses on long-term effectiveness rather than achieving maximum reward at every step, thereby ensuring better patient outcomes. We constructed a high-quality benchmark dataset for sequential diagnosis and treatment of diabetes and evaluated PrescDRL against this benchmark. Our results showed that PrescDRL achieved a higher curative effect, with the single-step reward improving by 117% and 153% compared to doctors. Furthermore, PrescDRL outperformed the benchmark in prescription prediction, with precision improving by 40.5% and recall improving by 63%. Overall, our study demonstrates the potential of using artificial intelligence to improve clinical intelligent diagnosis and treatment in TCM.

The HPLC-PDA Method for Simultaneous Determination of Regalosides from Bulbs of Lilium lancifolium Thunb. and Their Antioxidant Effects.

Lilium lancifolium Thunb. is a herbal medicine that is widely used to treat inflammation and lung diseases. In this study, a simultaneous quantitative method was developed for the quality control of BLL using high-performance liquid chromatography coupled with a photodiode array detector (HPLC-PDA), and their antioxidant effects were evaluated. Eight regalosides (i.e., regaloside A, B, C, E, F, H, I, and K) were selected as marker substances and separated on a Gemini C18 reversed-phase analytical column by gradient elution with distilled water-acetonitrile mobile phase containing 0.1% (v/v) formic acid. The method was validated with respect to linearity, sensitivities (limit of detection (LOD) and limit of quantitation (LOQ)), accuracy, and precision. The antioxidant effects of the extract and each component were evaluated using the 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay and 2-2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) assay. The coefficients of determination values used as indicators of linearity for all components were ≥0.9999. LOD and LOQ concentrations were 0.10-0.66 μg/mL and 0.29-2.01 μg/mL, respectively. The recovery was 95.39-103.925% (relative standard deviation; RSD ≤ 2.55%), and precision RSD was <2.78%. The HPLC-PDA method was applied to real samples, and all components were detected at 1.12-29.76 mg/freeze-dried g. The evaluation of antioxidant effects showed that regalosides C, E, and K exhibited significant antioxidant effects. Our knowledge will be appropriately utilized in raw material management and conducting clinical and non-clinical studies on L. lancifolium or herbal medicine prescriptions containing L. lancifolium.

Network pharmacology analysis revealed the mechanism and active compounds of jiao tai wan in the treatment of type 2 diabetes mellitus via SRC/PI3K/AKT signaling

Ethnopharmacological relevanceJiao-tai-wan (JTW) is a traditional Chinese herbal prescription, exerts its therapeutic effects on type 2 diabetes mellitus (T2DM). However, its mechanisms and active components remain unclear. Aim of the studyTo investigate the therapeutic mechanisms of JTW in treating type 2 diabetes mellitus (T2DM), focusing on identifying active components, their targets, and validating efficacy through SRC/PI3K/AKT signaling pathway modulation in vitro and in vivo. Materials and methodsActive ingredients were retrieved from the Traditional Chinese Medicine System Pharmacology (TCMSP) and Comprehensive Traditional Chinese Medicine Database (TCMID). Targets for these components were identified using the ChemMapper database based on 3D structural similarity. T2DM-related genes were sourced from the DisGeNET and Gene Expression Omnibus (GEO) databases. Protein-protein interaction (PPI) analysis and functional enrichment analysis were conducted to construct a pathway network of “herbs-active ingredients-candidate targets”, identifying core molecular mechanisms and key active ingredients. SwissDock was used for molecular docking to predict ligands for candidate targets. The diabetic models were established using C57BL/6 mice and human liver HepG2 cell lines. Their Effectiveness and key molecules were verified through biochemical detection and immunoblotting. ResultsTotal 30 active compounds, 597 active ingredient targets, 9631 T2DM-related genes, and 521 overlapping candidate targets were found for JTW on T2DM. Go enrichment indicated the core pathways enriched on insulin and glucose metabolism. The auto-docking demonstrated SRC has potential binds to ingredients of JTW. In vivo, JTW can reduce blood glucose, and blood lipid levels, and HOMA-IR, and increase HOMA-ISI levels in T2DM mice with reduced ALT, AST, MDA levels and increased SOD levels. Meanwhile, decreased phosphorylation of SRC, along with increased levels of phosphorylated PI3K, PI3K, and phosphorylated AKT, were observed. HE staining of liver tissues further confirmed that JTW administration improved liver morphology, reducing inflammation and necrosis. In vitro, JTW significantly ameliorates upstream dysregulation by reducing SRC phosphorylation while enhancing phosphorylated PI3K, PI3K, and AKT phosphorylation levels. ConclusionJTW may alleviate glucose, insulin resistance, and lipid metabolism disorders by the SRC/PI3K/AKT signaling pathway, that provide a novel view of potential active compounds and essential targets in treating T2DM.

Comprehensive evaluation of Chinese herbal compound prescriptions for postoperative spinal cord injury: A network meta-analysis of randomized controlled trials

BackgroundSpinal cord injury (SCI) is a catastrophic condition associated with spinal nerve damage, which can lead to complete or partial loss of sensory and motor functions. Chinese herbal compound prescriptions (CHCP) have shown varying degrees of therapeutic effects on spinal cord injuries. However, there is a significant lack of clinical evidence-based research to substantiate these effects. PurposeThis study aims to thoroughly assess the viability of CHCPs in postoperative SCI through network meta-analysis. MethodsComputer searches were conducted across multiple databases, including PubMed, Cochrane Library, Embase, Web of Science, CNKI, Wanfang, VIP, and CBM, from their inception until May 2024. The meta-analysis adhered to the PRISMA guidelines and was registered in the PROSPERO database (CRD42023462686). A network meta-analysis was performed using the BUGSnet software package via R. Study design: A network meta-analysis of randomized clinical trials (RCTs). ResultsA total of 26 RCTs involving 1848 patients were ultimately included. The network meta-analysis revealed the effectiveness in improving ASIA motor score as follows: “HQGZD” > “Other Decoctions” > “BYHWD” > “TDHXD” > “THCQD” > “Surgery”. For ASIA sensory score, the effectiveness ranking was: “HQGZD” > “Other Decoctions” > “BYHWD” > “TDHXD” > “THCQD” > “Surgery”. Additionally, the experimental group had a higher ADL score compared to the control group, with a statistically difference [SMD = 1.08, 95 % CI = (0.88, 1.27), p < 0.05]. The experimental group had fewer adverse events compared to the control group, with a statistically difference [RR = 0.41, 95 % CI (0.22, 0.78), p < 0.05]. ConclusionThe findings suggest that CHCP can mprove postoperative ASIA motor and sensory scores, enhance ADL scores, and reduce adverse events following SCI surgery. Specifically, combining surgery with Huangqi Guizhi Wuwu Decoction or Buyang Huanwu Decoction may provide superior therapeutic effects in SCI treatment. Integrating CHCP into postoperative care for SCI patients may offer potential benefits.

An Integrated Approach Using Network Pharmacology and Experimental Validation to Reveal the Therapeutic Mechanism of Weifuchun in Treating Gastric Cancer.

Gastric cancer (GC) is a prevalent malignancy affecting the gastrointestinal tract. Weifuchun (WFC), a Chinese herbal prescription comprising red ginseng, Isodon amethystoides, and Fructus aurantii, is widely used in China for various chronic stomach disorders. However, its therapeutic role and mechanisms in treating GC remain unexplored. In a randomized, controlled, single-blind trial involving postoperative stages II and III GC patients, we compared adjuvant chemotherapy plus WFC (chemo plus WFC group) to adjuvant chemotherapy alone (chemo group) over 6 months. We assessed recurrence and metastasis rates and used systematic pharmacology to predict WFC's active components, screen target genes, and construct network interaction maps, were validated through in vitro experiments. The combined therapy significantly reduced 2-year recurrence and metastasis rates. We identified 67 active ingredients, 211 drug target proteins, 1539 disease targets, 105 shared targets, and 188 signaling pathways associated with WFC. WFC impacted cell apoptosis, proliferation, and the inflammatory response, with top tumor-related signaling pathways involving 5'-adenosine monophosphate-activated protein kinase (AMPK), mitogen-activated protein kinase, nuclear factor kappa-B (NFKB), and apoptosis. In vitro, WFC inhibited proliferation and migration while inducing apoptosis in GC cells, reduced VEGFA, TNFa, and IL6 expressions. Immunocytochemistry showed increased p-AMPK staining, and molecular analysis revealed decreased NFKB and phosphorylation of extracellular-regulated protein kinase 1/2 (ERK1/2) levels, increased p-AMPK and BAX protein levels in WFC-treated cells, effects reversed by Compound C. WFC's antitumor effects involve AMPK-dependent ERK1/2 and NFKB pathways, regulating proliferation, migration, and apoptosis in GC cells.

Exploration of the Mechanisms of Bu-Yang-Huan-Wu Decoction in the Treatment of Diabetic Peripheral Neuropathy by Integrating of Serum Pharmacochemistry and Network Pharmacology.

Diabetic peripheral neuropathy (DPN) is a significant and frequent complication of diabetes. Bu-Yang-Huan-Wu Decoction (BHD) is a classic traditional Chinese herbal prescription that is commonly used in modern clinical practice for the effective treatment of DPN, but the underlying mechanism is not yet clearly defined. The chemical constituents of BHD were characterized by UPLC-Q-Orbitrap HR MS/MS, and a total of 101 chemical components were identified, including 30 components absorbed into blood. An interaction network of "compound-target-disease" interactions was constructed based on the compounds detected absorbed in blood and their corresponding targets of diabetic neuropathy acquired from disease gene databases, and the possible biological targets and potential signalling pathways of BHD were predicted via network pharmacology analysis. Subsequently, methylglyoxal-induced (MGO-induced) Schwann cells (SCs) were used to identify the active ingredients in blood components of BHD and verify the molecular mechanisms of BHD. Through network topological analysis, 30 shared targets strongly implicated in the anti-DPN effects of BHD were identifed. Combined network pharmacology and in vitro cellular analysis, we found that the active ingredient of BHD may treat DPN by modulating the AGEs/RAGE pathway. This study provides valuable evidence for future mechanistic studies and potential therapeutic applications for patients with DPN.

Calamine in the ophthalmic external treatment prescription in ancient times

Calamine and its related medicines came into China as articles of tribute from other countries in ancient times. It was not recorded in the books of Chinese materia medica before the Song Dynasty but was widely used in ophthalmology, dermatology and traumatology and was, recorded specifically in the Ming and Qing Dynasty. This paper systematically examines the evolution of calamine herb in the archives of traditional Chinese medicine in terms of ophthalmic eternal treatment prescriptions. It was found that a total of 320 ophthalmic treatment formulas or prescriptions involved calamine, mainly finding its expression in 67 books on herbal medicines, formula and prescriptions, clinical syndrome comprehension and ophthalmic monographs. It was also found that calamine, as an important ophthalmic external medicine, had a wide range of clinical applications, covering internal and external obstructive eye diseases. Its flexibility, diverse compatibility and use in various processing are of great value and significance for in-depth exploration of its current application, its further use in ophthalmic treatment formulas or prescriptions and the redevelopment of classic formulas and prescriptions as well.

Exploring the high-quality ingredients and mechanisms of Da Chuanxiong Formula in the treatment of neuropathic pain based on network pharmacology, molecular docking, and molecular dynamics simulation

Da Chuanxiong Formula (DCXF) is a traditional herbal prescription used for pain management. It consists of Chuanxiong Rhizoma (CR) and Gastrodiae Rhizoma (GR). Despite its long history of use, the underlying therapeutic mechanism of DCXF remains insufficiently understood. Therefore, in this study, key target genes were obtained through network pharmacology research methods and molecular docking techniques, including transient receptor potential vanilloid 1 (TRPV1), adenosine A2a receptor (ADORA2A), nuclear receptor subfamily 3 group C member 1 (NR3C1), and protein kinase C beta (PRKCB). Molecular dynamics simulations demonstrated the favorable binding between all four key genes and their corresponding compounds. Notably, chronic constriction injury (CCI) treatment resulted in a significant decrease in mechanical threshold and thermal latency period for rat foot contraction, which was ameliorated upon administration of DCXF. Furthermore, real-time quantitative reverse transcription PCR (RT-qPCR) and western blot (WB) analyses indicated an upregulation of TRPV1, ADORA2A, NR3C1, and PRKCB expression in the rat dorsal root ganglion following CCI, which was attenuated by treatment with DCXF. The expressions of inflammatory factors, including tumor necrosis factor-α (TNF-α), interleukin 1 beta (IL-1β), and interleukin 6 (IL-6), in the rat dorsal root ganglion were assessed using ELISA, confirming consistent trends with the aforementioned findings. The results of this study offer a promising theoretical foundation for the utilization of DCXF in the treatment of neuropathic pain (NP).

The compound agents and isorhynchophylline played a role in regulating the stress indices of mice after the simulating transport processs and have the effect of significantly alleviating the transport stress response in mice, with a view to provide reference for alleviating the adverse effects of transport stress on the animal husbandry industry.

Lingdan: enhancing encoding of traditional Chinese medicine knowledge for clinical reasoning tasks with large language models.

The recent surge in large language models (LLMs) across various fields has yet to be fully realized in traditional Chinese medicine (TCM). This study aims to bridge this gap by developing a large language model tailored to TCM knowledge, enhancing its performance and accuracy in clinical reasoning tasks such as diagnosis, treatment, and prescription recommendations. This study harnessed a wide array of TCM data resources, including TCM ancient books, textbooks, and clinical data, to create 3 key datasets: the TCM Pre-trained Dataset, the Traditional Chinese Patent Medicine (TCPM) Question Answering Dataset, and the Spleen and Stomach Herbal Prescription Recommendation Dataset. These datasets underpinned the development of the Lingdan Pre-trained LLM and 2 specialized models: the Lingdan-TCPM-Chat Model, which uses a Chain-of-Thought process for symptom analysis and TCPM recommendation, and a Lingdan Prescription Recommendation model (Lingdan-PR) that proposes herbal prescriptions based on electronic medical records. The Lingdan-TCPM-Chat and the Lingdan-PR Model, fine-tuned on the Lingdan Pre-trained LLM, demonstrated state-of-the art performances for the tasks of TCM clinical knowledge answering and herbal prescription recommendation. Notably, Lingdan-PR outperformed all state-of-the-art baseline models, achieving an improvement of 18.39% in the Top@20 F1-score compared with the best baseline. This study marks a pivotal step in merging advanced LLMs with TCM, showcasing the potential of artificial intelligence to help improve clinical decision-making of medical diagnostics and treatment strategies. The success of the Lingdan Pre-trained LLM and its derivative models, Lingdan-TCPM-Chat and Lingdan-PR, not only revolutionizes TCM practices but also opens new avenues for the application of artificial intelligence in other specialized medical fields.

Bushen Zhuyun Decoction Improves Endometrial Receptivity by Inhibiting NF-κB/NLRP3 Signaling Pathway.

Bushen Zhuyun Decoction (BSZY), a traditional Chinese herbal prescription has shown promising effects on gynecological infertility, but the mechanism for endometrial receptivity is still unclear. This study aimed to investigate the regulatory effects of BSZY on endometrial receptivity, which plays a key role in colonization of embryo, and its regulatory mechanisms associated with NF- κB/NLRP3 pathway. SD rats at reproductive age with affected endometrial receptivity was established using mifepristone (RU486), and the regulatory effects of BSZY on endometrial receptivity were evaluated by H&E staining, and changes in sex hormones by ELISA and Western blot. Moreover, human endometrial RL95-2 cells were treated with H2O2, and inflammatory cytokines in rats and RL95-2 cells were analyzed by ELISA. The activation of NF-κB/NLRP3 signaling pathway in RL95-2 cells were characterized using immunofluorescence and Western blot. Mitochondrial morphology and function in RL95-2 cells were observed by transmission electron microscope and cell mitochondrial stress test. BSZY increased uterine endometrial thickness and attenuate histopathological changes induced by RU486. BSZY can regulate endometrial estrogen receptor and progesterone receptor, and the levels of sex hormones and inflammatory cytokines in pregnant rats. BSZY-containing serum also showed strong anti-inflammatory and cytoprotective effects in vitro. In addition, BSZY-containing serum inhibited the activation of NF-κB/NLRP3 signaling pathway, and improve mitochondrial morphology and function in RL95-2 cells. BSZY can improve endometrial receptivity, potentially by improving mitochondrial morphology and function to inhibit the activation of NF-κB/NLRP3 signaling pathway in endometrial cells, thus regulate inflammation to improve endometrial receptivity.

Integrated metabolomics and serum-feces pharmacochemistry-based network pharmacology to reveal the mechanisms of an herbal prescription against ulcerative colitis

BackgroundCDD-2103 is an herbal prescription used to treat ulcerative colitis (UC). This study aimed to uncover its mechanism by integrating metabolomics and serum-feces pharmacochemistry-based network pharmacology. MethodsA DSS-induced chronic colitis mice model was used to evaluate the anti-colitis effect of CDD-2103. Serum and feces metabolomics were conducted to identify differential metabolites and pathways. In the serum-feces pharmacochemistry study, biological samples were collected from rats treated with CDD-2103. Then, network pharmacology was utilized to predict the targets of the identified compounds. Critical genes were extracted through the above-integrated analysis. The interactions between targets, CDD-2103, and its compounds were validated through molecular docking, immunoblotting, and enzyme activity assays. ResultsCDD-2103 alleviated ulcerous symptoms and colonic injuries in colitis mice. Metabolomics study identified differential metabolites associated with tryptophan, glycerophospholipid, and linoleic acid metabolisms. The serum-feces pharmacochemistry study revealed twenty-three compounds, which were subjected to network pharmacology analysis. Integration of these results identified three key targets (AHR, PLA2, and PTGS2). Molecular docking showed strong affinities between the compounds and targets. PTGS2 was identified as a hub gene targeted by most CDD-2103 compounds. Immunoblotting and enzyme activity assays provided further evidence that CDD-2103 alleviates UC, potentially through its inhibitory effect on cyclooxygenase-2 (COX-2, encoded by PTGS2), with alkaloids and curcuminoids speculated as crucial anti-inflammatory compounds. ConclusionThis integrated strategy reveals the mechanism of CDD-2103 and provides insights for developing herbal medicine-based therapies for UC.

Results of Chemical and Pharmacological Studies of the Mongolian Traditional Prescription "Arur-10"

This study examines ARUR-10, the herbal prescription commonly utilized in Traditional Mongolian Medicine practices for the treatment of kidney disease and the improvement of physical strength. This investigation aims to establish a profile of the biologically active compounds, antioxidant activity, and the anti-inflammatory impact on the kidneys in the traditional ARUR-10 prescription. For this analysis, we used Thin-Layer Chromatography (TLC) to identify phenolic compounds in the traditional prescription. Quantification of these bioactive substances was determined by UV/Vis spectrophotometry. The traditional ARUR-10 prescription, or traditional drug, had a higher polyphenolic content of 12.9±0.361% (gallic acid equivalent) and a sum flavonoid content of 0.33±0.015% (Rutin equivalent). The antioxidant activity was measured using the inhibiting free radical’s DPPH method and evaluated using the IC50 value. The 100 μg/ml concentration inhibited free radicals by 68.47%, whereas 200 μg/ml inhibited them by 83.29%, with an IC50 of 92.4 μg/ml. This study concluded that the traditional ARUR-10 prescription contains many polyphenolic compounds and flavonoids and has antioxidant properties. ARUR-10 has a moderate level of toxicity and no signs of chronic toxicity have been detected. Urine excretion was 1.52 ± 1.23 times higher than in the distilled water group (0.97 ± 0.71). ARUR-10 at doses of 240 mg/kg (1.62±1.14) had a similar effectiveness to Hydrochlorothiazide (1.52±1.23). In the gentamicin-induced nephritis model, ARUR-10 reduced serum creatinine by 42.8%, uric acid by 14.9%, and urea by 32% at doses of 240 mg/kg, compared to the control group that produced the pathological model. It had a protective effect on the kidneys by preserving the tube structure; cell death and cell necrosis were not observed.

Simultaneous Analysis of Thirteen Compounds in Yeokwisan Using High-Performance Liquid Chromatography-Photodiode Array Detection and Ultra-Performance Liquid Chromatography-Tandem Mass Spectrometry and Their Antioxidant Effects.

Yeokwisan (YWS) is an herbal medicine prescription consisting of six oriental herbal medicines, developed to treat reflux esophagitis. We focused on developing an analytical method capable of simultaneously quantifying 13 compounds in YWS samples using high-performance liquid chromatography-photodiode array detection (HPLC-PDA) and ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) and exploring their antioxidant effects. All compounds examined in both analytical systems were chromatographically separated on a SunFireTM C18 (4.6 × 250 mm, 5 μm) column and an Acquity UPLC BEH C18 (2.1 × 100 mm, 1.7 μm) column using gradient elution of a water-acetonitrile mobile phase. Antioxidant effects were evaluated based on radical scavenging activity (DPPH and ABTS tests) and ferrous ion chelating activity. In two analytical methods, the coefficient of determination of the regression equation was ≥0.9965, the recovery range was 81.11-108.21% (relative standard deviation (RSD) ≤ 9.33%), and the precision was RSD ≤ 11.10%. Application of the optimized analysis conditions gave quantitative analysis results for YWS samples of 0.02-100.36 mg/g. Evaluation of the antioxidant effects revealed that baicalein and baicalin exhibit significant antioxidant activity, suggesting that they play an important role in the antioxidant effects of YWS.

Network Pharmacology and Experimental Validation of Qingwen Baidu Decoction Therapeutic Potential in COVID-19-related Lung Injury.

Coronavirus disease 2019 (COVID-19) is a lifethreatening disease worldwide due to its high infection and serious outcomes resulting from acute lung injury. Qingwen Baidu decoction (QBD), a well-known herbal prescription, has shown significant efficacy in patients with Coronavirus disease 2019. Hence, this study aims to uncover the molecular mechanism of QBD in treating COVID-19-related lung injury. Traditional Chinese Medicine Systems Pharmacology database (TCMSP), DrugBanks database, and Chinese Knowledge Infrastructure Project (CNKI) were used to retrieve the active ingredients of QBD. Drug and disease targets were collected using UniProt and Online Mendelian Inheritance in Man databases (OMIM). The core targets of QBD for pneumonia were analyzed by the Protein-Protein Interaction Network (PPI), Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) to reveal the underlying molecular mechanisms. The analysis of key targets using molecular docking and animal experiments was also validated. A compound-direct-acting target network mainly containing 171 compounds and 110 corresponding direct targets was constructed. The key targets included STAT3, c-JUN, TNF-α, MAPK3, MAPK1, FOS, PPARG, MAPK8, IFNG, NFκB1, etc. Moreover, 117 signaling pathways mainly involved in cytokine storm, inflammatory response, immune stress, oxidative stress and glucose metabolism were found by KEGG. The molecular docking results showed that the quercetin, alanine, and kaempferol in QBD demonstrated the strongest affinity to STAT3, c- JUN, and TNF-α. Experimental results displayed that QBD could effectively reduce the pathological damage to lung tissue by LPS and significantly alleviate the expression levels of the three key targets, thus playing a potential therapeutic role in COVID-19. QBD might be a promising therapeutic agent for COVID-19 via ameliorating STAT3-related signals.

QingChang-XiaoPi decoction ameliorates intestinal inflammation of ulcerative colitis by regulating the pathogenicity of Th17 cells

BackgroundQingChang-XiaoPi Decoction (QCXPY), a Chinese herbal prescription, has been employed in the treatment of ulcerative colitis (UC) in China. However, its molecular mechanism of action in UC remains unclear. PurposeTo elucidate the therapeutic effects of QCXPY against UC and reveal its mechanism of action. Study DesignWe conducted a single-arm observation to evaluate the clinical efficacy of QCXPY in patients with mild-to-moderate UC. Inclusion and exclusion criteria were established to ensure the eligibility of participants, with a focus on excluding patients with specific conditions or complications that could confound the results. MethodsThe expression of inflammatory factors in patients’ serum was detected using a Luminex assay. The main components of QCXPY were identified using UHPLC-Q-TOF-MS. Network pharmacology was employed to predict potential therapeutic targets and their mechanisms of action. The efficacy of QCXPY was evaluated using a dextran sulfate sodium (DSS)-induced mouse model. Disease activity index (DAI), histopathological score, cytokine detection by ELISA, T-helper 17 (Th17) cell proportion by flow cytometry, expression of the IL-23/IL-17 axis, and changes in the levels of its downstream effectors were detected by immunohistochemistry, immunofluorescence, and western blotting. ResultsQCXPY could alleviate the symptoms of diarrhea, abdominal pain, abdominal distension, and purulent stool in patients with mild-to-moderate UC. Moreover, it reduced the expression of IL-6, IL-17, and IL-23 in serum; alleviated DSS-induced experimental colitis in mice; reduced DAI, pathological scores, and the expressions of IL-6, IL-17, and IL-23 in colon tissue; and decreased the proportion of pathogenic Th17 cells and the expression of STAT3 and phospho-STAT3. ConclusionThis study confirmed for the first time that QCXPY could alleviate intestinal symptoms, reduce the levels of serum inflammatory factors, and improve the quality of life of patients with mild-to-moderate UC. Its mechanism of action may involve reducing the secretion of inflammatory cytokines, moderating the pathogenicity of Th17 cells, and inhibiting STAT3 phosphorylation, thereby alleviating intestinal inflammation in UC.
