Background Impairment of the intracranial lymphatic drainage system significantly contributes to Alzheimer’s disease (AD) by facilitating the accumulation of neurotoxic amyloid-β (Aβ) and tau proteins. Restoring lymphatic function offers a promising preventive strategy against early-stage AD pathology. Purpose This study aimed to evaluate the effects and mechanisms of Cerebralcare Granule® (CG), a traditional Chinese medicine formula, on cognitive impairment and pathological markers in AD mouse models by modulating intracranial lymphatic clearance pathways. Methods Six-month-old APP/PS1 transgenic mice and wild-type controls received oral administration of CG or donepezil for two months. Behavioral assessments included the Morris water maze, open field, Y-maze, novel object recognition, and passive avoidance tests. Immunohistochemistry, immunofluorescence, and Western blot analyses were used to assess Aβ deposition, glymphatic clearance, astrocytic aquaporin-4 (AQP4) polarization, meningeal lymphangiogenesis, and blood-brain barrier integrity. Tracer-based in vivo imaging confirmed improved CSF influx and efflux dynamics. Brain-penetrant compounds of CG were identified using UPLC-MS/MS, MALDI-TOF-MS imaging, and network pharmacology. Results CG treatment significantly improved cognitive performance, reduced Aβ burden, enhanced glymphatic transport, and promoted meningeal lymphatic drainage in APP/PS1 mice. CG restored perivascular AQP4 polarization, improved cerebrospinal fluid-interstitial fluid exchange, facilitated waste removal to cervical lymph nodes, and protected the integrity of the blood-brain barrier. Major brain-penetrant compounds—paeoniflorin, rhynchophylline, and ethyl gallate—were found to target lymphatic signaling pathways (AQP4, VEGFC, VEGFR3, PROX1) effectively. Conclusion CG exerts protective effects against cognitive impairment and AD pathology by reinforcing the structural and functional integrity of the intracranial lymphatic drainage system, highlighting a novel therapeutic avenue for proactive brain health management in early-stage AD.
This study presents the development of a flexible ultrasonic transducer array with automatic phase calibration (FUT-APC) for high-resolution carotid artery imaging and continuous monitoring of vascular mechanical parameters. The transducer integrates element position sensing with real-time phase compensation, utilizing five flexible pressure sensors to reconstruct the curvature profile of the attached surface with a reconstruction error as low as 0.34 mm. The system maintains stable operation on complex curved surfaces, significantly improving imaging quality compared to conventional probes on bent or irregular geometries. A contact pressure visualization mechanism enables real-time monitoring of applied pressure, ensuring data consistency during long-term measurements. The FUT-APC has a center frequency of 4.6 MHz, a -6 dB focal width of 0.74 mm, and a bandwidth of 53 %. In phantom tests, the system achieved axial resolution better than 0.75 mm and lateral resolution better than 0.93 mm. In vivo testing successfully captured the dynamic diameter variations of the carotid arterial wall and, together with wall thickness measurements, enabled extraction of key mechanical parameters, including circumferential stress (83.1 kPa), strain (7.09 %), and static elastic modulus (1.17 MPa). The FUT-APC offers a wearable and accurate solution for early screening, risk assessment, and dynamic tracking of atherosclerosis.
Tourette syndrome (TS), predominantly affecting children and adolescents aged 2–15 years, significantly impairs quality of life and social functioning. Shaoma Zhijing granules (SMZJG), a compound traditional Chinese medicine (TCM), has demonstrated comparable efficacy to tiapride (TIA) in alleviating TS symptoms with fewer adverse effects. To elucidate its tmaterial basis and mechanism of action, we employed iminodipropionitrile (IDPN) and 2, 5-dimethoxy-4-iodoarylamine (DOI) to induce a rat model of TS. SMZJG treatment significantly ameliorated IDPN- and DOI-induced stereotyped behavioral impairments and effectively counteracted the reduction in striatum volume. Notably, SMZJG was found to markedly correct neurotransmitter imbalances, suppress M1 microglial activation, and reduce the levels of interleukin-1α (IL-1α), interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and monocyte chemoattractant protein-1 (MCP-1) in serum. These findings collectively suggest that SMZJG alleviates TS-associated behavioral disorders, potentially through mechanisms such as reducing striatal atrophy, modulating neurotransmitter imbalances, regulating abnormal neurotransmitter receptor expression, and decreasing microglial proliferation as well as levels of pro-inflammatory cytokines and chemokines in serum.
Background: Vascular calcification refers to the abnormal accumulation of calcium in the walls of blood vessels and is a risk factor often overlooked in cardiovascular disease. However, there is currently no specific drug for treating vascular calcification. Compound Danshen Dripping Pill (CDDP) is widely used to treat cardiovascular diseases, but its effect on vascular calcification has not been reported. Purpose: We investigated the effects of CDDP on vascular calcification in ApoE-/- mice and in vitro and elucidated its mechanism of action. Study design: Firstly, we found that CDDP has the potential to improve calcification based on network pharmacology analysis. Then, we performed the following experiments: in vivo, ApoE-/- mice were fed a high-fat diet randomly supplemented with CDDP for 16 weeks. Atherosclerosis and vascular calcification were determined. In vitro, human aortic smooth muscle cells (HASMCs), human umbilical vein endothelial cells (HUVECs), and human aortic endothelial cells (HAECs) were used to determine the mechanisms for CDDP-inhibited vascular calcification. Results: In this study, we observed that CDDP reduced intimal calcification in atherosclerotic lesions of ApoEdeficient mice fed a high-fat diet, as well as the calcification in cultured SMCs and ECs. Mechanistically, CDDP inhibited the Wnt/beta-catenin pathway by up-regulating the expression of DKK1 and LRP6, which are upstream inhibitors of Wnt, leading to a reduction in the expression of osteoblastic transition markers (ALP, OPN, BMP2, and RUNX2). Furthermore, CDDP enhanced the secretion of DKK1, which plays a role in mediating ECSMC crosstalk in calcification. Additionally, VC contributes to vascular aging by inhibiting Sirt1 and increasing senescence parameters (SA-beta-gal, p21, and p16). However, CDDP reversed these changes by activating Sirt1. CDDP also reduced the levels of pro-inflammatory cytokines and the senescence-associated secretory phenotype in vivo and in vitro. Conclusions: Our study suggests that CDDP reduces vascular calcification by regulating the DKK1/LRP6/beta-catenin signaling pathway in ECs/SMCs and interactions with the crosstalk of ECs and SMCs. It also reduces the senescence of ECs/SMCs, contributing to the Sirt1 activation, indicating CDDP's novel role in ameliorating vascular calcification.
Objective 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.Materials and Methods 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.Results 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.Conclusion 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.

BACKGROUND:Tourette syndrome (TS) represents a neurodevelopmental disorder characterized by an uncertain etiology and influencing factors. Frequently, it co-occurs with conditions such as attention deficit hyperactivity disorder, obsessive-compulsive disorder, and sleep disturbances, which have garnered substantial attention from the research community in recent years. Clinical trials have demonstrated that Shaoma Zhijing Granules (SMZJG, 5-ling granule, also known as TSupport or T92 under U.S. development), a traditional Chinese medicine compound, is an effective treatment for TS.PURPOSE:To conduct scientometric analysis on developing trends, research countries and institutions, current status, hot spots of TS and discuss the underlying mechanisms of SMZJG and its main components on TS. The aim is to provide valuable reference for ongoing clinical and basic research on TS and SMZJG.STUDY DESIGN & METHODS:Using Tourette syndrome, SMZJG and its main components along with their synonyms as keywords, we conducted a comprehensive search across major scientific databases including the Web of Science Core Collection, PubMed and China National Knowledge Infrastructure (CNKI) databases. A total of 5952 references and 99 patents were obtained. Among these, 5039 articles and reviews, as well as 54 patents were analyzed by Citespace and VOSviewer software.RESULTS:The available evidence indicates that the SMZJG's components likely exert their mechanisms in treating TS by regulating the dopaminergic pathway system, neurotransmitter imbalances, reducing neuroinflammation, promoting the repair of nerve damage and improving sleep disorders.CONCLUSION:This comprehensive analysis lays the foundation for an extensive exploration of the feasibility and clinical applications of SMZJG in TS treatment.
Objective: This study aimed to explore andrographolide’s mechanism of action and its protective effect on noise-induced hearing loss (NIHL). Materials and Methods: A mice animal model for NIHL was established through exposure to broadband noise at 120 dB sound pressure level for 4 h. Transcriptomics analysis and pharmacodynamic experiments were carried out. Results: Andrographolide enters the inner ear and effectively prevents hearing damage following noise exposure in the mice model for permanent hearing loss. Moreover, treatment with andrographolide inhibited the excessive activation of inflammatory factors in the cochleae of noise-exposed mice. Conclusion: Andrographolide might be a promising candidate for auditory protective drug investigation.
Heart failure is the leading cause of death worldwide. Compound Danshen Dripping Pill (CDDP) or CDDP combined with simvastatin has been widely used to treat patients with myocardial infarction and other cardiovascular diseases in China. However, the effect of CDDP on hypercholesterolemia/atherosclerosis-induced heart failure is unknown. We constructed a new model of heart failure induced by hypercholesterolemia/atherosclerosis in apolipoprotein E (ApoE) and LDL receptor (LDLR) dual deficient (ApoE-/-LDLR-/-) mice and investigated the effect of CDDP or CDDP plus a low dose of simvastatin on the heart failure. CDDP or CDDP plus a low dose of simvastatin inhibited heart injury by multiple actions including anti-myocardial dysfunction and anti-fibrosis. Mechanistically, both Wnt and lysine-specific demethylase 4A (KDM4A) pathways were significantly activated in mice with heart injury. Conversely, CDDP or CDDP plus a low dose of simvastatin inhibited Wnt pathway by markedly up-regulating expression of Wnt inhibitors. While the anti-inflammation and anti-oxidative stress by CDDP were achieved by inhibiting KDM4A expression and activity. In addition, CDDP attenuated simvastatin-induced myolysis in skeletal muscle. Taken together, our study suggests that CDDP or CDDP plus a low dose of simvastatin can be an effective therapy to reduce hypercholesterolemia/atherosclerosis-induced heart failure.
BackgroundLong-term use of nitrates for treating stable angina pectoris (SAP) may lead to patients' tolerance to nitrates. As a traditional Chinese medicine, Compound danshen dropping pills (CDDP) is beneficial for patients with SAP. This study aimed to critically assess the efficacy and safety of CDDP vs. nitrates for SAP.MethodsPubMed, Embase, Web of Science, Cochrane library, CNKI, Wanfang Digital Periodicals, and Chinese Science and Technology Periodicals database were searched from inception to April 2023. Randomized controlled trials (RCTs) comparing CDDP with nitrates for SAP were included. The meta-analysis was conducted to estimate the pooled effect.ResultsTwenty-nine studies were included for the statistical analysis. The meta-analyses with the random-effect model indicated that CDDP could significantly increase the effective rate in symptom improvement compared with nitrates (Pooled 9 RCTs, OR = 1.95, 95% CI: 1.25–3.05, P = 0.003, duration of 4 weeks; Pooled 4 RCTs, OR = 3.45, 95% CI: 1.84–6.48, P = 0.0001, duration of 6 weeks; Pooled 13 RCTs, OR = 4.02, 95% CI: 2.14–7.57, P < 0.0001, duration of 8 weeks). The meta-analyses with the random-effect model indicated that CDDP could significantly increase the effective rate in electrocardiogram improvement compared with nitrates (Pooled 5 RCTs, OR = 1.60, 95% CI: 1.02–2.52, P = 0.04, duration of 4 weeks; Pooled 3 RCTs, OR = 2.47, 95% CI: 1.60–3.82, P < 0.0001, duration of 6 weeks; Pooled 11 RCTs, OR = 3.43, 95% CI: 2.68–4.38, P < 0.00001, duration of 8 weeks). The incidence of adverse drug reactions in the CDDP group was lower than that in the nitrates group (Pooled 23 RCTs, OR = 0.15, 95% CI: 0.1–0.21, P < 0.00001). The results of the meta-analyses with fixed-effect model were similar with above results. The levels of the evidence ranged from very low to low.ConclusionThe present study suggests that CDDP with the duration of at least 4 weeks can be considered as an alternative to nitrates for treating SAP. However, more high-quality RCTs are still needed to confirm these findings.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022352888, identifier [CRD42022352888].
Traditional Chinese medicine (TCM) has used herbal remedies for more than 2,000 years. The use of complimentary therapies has increased dramatically during the last years, especially in the West, and the incorporation and modernization of TCM in current medical practice is gaining momentum. We reflect on the main bottlenecks in the modernization of arcane Chinese herbal medicine: lack of standardization, safety concerns and poor quality of clinical trials, as well as the ways these are being overcome. Progress in these areas will facilitate the implementation of an efficacy approach, in which only successful clinical trials lead to the molecular characterization of active compounds and their mechanism of action. Traditional pharmacological methodologies will produce novel leads and drugs, and we describe TCM successes such as the discovery of artemisinin as well as many others still in the pipeline. Neurodegenerative diseases, such as Parkinson's and Alzheimer's disease, cancer and cardiovascular disease are the main cause of mortality in the Western world and, with an increasing old population in South East Asia, this trend will also increase in the Far East. TCM has been used for long time for treating these diseases in China and other East Asian countries. However, the holistic nature of TCM requires a paradigm shift. By changing our way of thinking, from "one-target, one-drug" to "network-target, multiple-component-therapeutics," network pharmacology, together with other system biology methodologies, will pave the way toward TCM modernization.
Diabetic retinopathy (DR) is increasingly becoming a main complication of diabetes, and is difficult to cure. In our research, network pharmacology analysis suggested that both compound Danshen dripping pills (CDDP) and bezafibrate (BZF) have potential protective effects against DR and the two drugs may act synergistically. The pharmacological effects of the coadministration of CDDP and BZF were elucidated in db/db mice, which simulate DR. Fluorescein fundus angiography showed that coadministration attenuated vascular leakage. Optical coherence tomography and hematoxylin and eosin staining showed that coadministration improved retinal thickness better than CDDP monotherapy. In addition, cell fluorescence images of reactive oxygen species revealed that coadministration of CDDP and BZF had more potent effects against oxidative stress than CDDP monotherapy. Metabolomics analysis showed that coadministration reduced the ratio of oxidized glutathione to reduced glutathione further than CDDP monotherapy. Coadministration of CDDP and BZF may provide additional protective effects by resisting vascular leakage, increasing retinal thickness, and inhibiting inflammation and oxidative stress in DR.
Borneol (Bingpian), a monoterpenoid pharmaceutical ingredient, is commonly used as a main composition in traditional Chinese medicine preparations such as compound Danshen dropping pills (CDDP) and has also been approved by the U.S. Food and Drug Administration as a flavoring substance or adjuvant in food. Borneol plays a regulating and guiding role as a messenger drug in CDDP. However, the effect of borneol on the pharmacokinetics of the components of CDDP in human plasma is unclear. In this study, we investigate the effects of borneol on the pharmacokinetics of ginsenoside Rb1 (Rb1 ), ginsenoside Rg1 (Rg1 ), and notoginsenoside R1 (NR1 ) in CDDP. We used a double-cycle crossover-administration model in 12 healthy male volunteers, administered CDDP with borneol (drug T) and without borneol (drug R). The selective response monitoring mode was used for MS quantification in the positive mode. As a result, we found that borneol could significantly affect the pharmacokinetic parameters of notoginsenosides and increase the absorption and systemic exposure of Rb1 , Rg1 , and NR1 in human plasma by ~1.85-3.71 times.
Benefiting from the development of network pharmacology, Traditional Chinese Medicine (TCM) shows great potential in modern drug discovery. Recently, more and more TCM-related databases have been established for both academic and industry research, but they are still insufficient in data standardization, integrity, and precision. To better accelerate the TCM research and overcome these shortcomings, we construct a web-based TCM platform, LTM-TCM, which is currently the most comprehensive TCM database that includes the following advantages: (1) High-quality data integration from fourteen TCM authoritative databases, especially with additional manual collected 41,025 clinical treatment records and 213 ancient Chinese medical books. (2) Accurate correction of multi-source TCM interactions (between symptoms, prescriptions, herbs, ingredients and targets) through in-house Biomedical Natural Language Processing (BioNLP) approaches in more than 30 million articles. (3) Diverse cross-field pipelines (e.g., bioactive ingredients screening, targets prediction, and mechanism prediction, etc.) help integrating traditional medicine with modern science in common aspects at both the molecular and phenotypic levels. In summary, LTM-TCM contains 1928 symptoms, 48,126 prescriptions, 9122 plants, 34,967 ingredients, 13,109 targets and 1170,133 interactions among all TCM related components. LTM-TCM has both Chinese and English interfaces, and it is accessible at http://cloud.tasly.com/#/tcm/home.
Diabetic retinopathy (DR), a diabetic microangiopathy caused by diabetes, affects approximately 93 million people, worldwide. However, the drugs used to treat DR have limited efficacy and the variety of side effects. This is possibly because the complicated pathogenesis of DR is associated with multiple proteins. In this work, we attempted to identify potential drugs against DR-associated proteins and predict potential targets for drugs using in silico prediction of chemical-protein interactions (CPI) based on multitarget quantitative structure-activity relationship (mt-QSAR) method. Therefore, we developed 128 binary classifiers to predict the CPI for 15 DR targets using random forest (RF), k-nearest neighbours (KNN), support vector machine (SVM), and neural network (NN) algorithms with MACCS, extended connectivity fingerprints (ECFP6) fingerprints, and protein descriptors. In order to facilitate discovery of the novel drugs and target identification using the 128 binary classifiers, a free web server (DRDB) was developed. Compound Danshen Dripping Pills (CDDP), composed of Salvia miltiorrhiza, Panax notoginseng, and borneol, is commonly used in the treatment of cardiovascular diseases. To explore the applicability of DRDB, the potential CPIs of CDDP in treatment of DR were investigated based on DRDB. In vitro experimental validation demonstrated that cryptotanshinone and protocatechuic acid, two key components of CDDP, are capable of targeting ICAM-1 which is one of the key target of DR. We hope that this work can facilitate development of more effective clinical strategies for the treatment of DR.
It is clinical reported that YangXue QingNao Wan (YXQNW) combined with donepezil can significantly improve the cognitive function of AD patients. However, the mechanism is not clear. A network pharmacology approach was employed to predict the protein targets and affected pathways of YXQNW in the treatment of AD. Based on random walk evaluation, the correlation between YXQNW and AD was calculated; while a variety of AD clinical approved Western drugs were compared. The targets of YXQNW were enriched and analyzed by using the TSEA platform and MetaCore. We proved that the overall correlation between YXQNW and AD is equivalent to clinical Western drugs, but the mechanism of action is very different. Firstly, YXQNW may promote cerebral blood flow velocity by regulating platelet aggregation and the vasoconstriction/relaxation signal pathway, which has been verified by clinical meta-analysis. Secondly, YXQNW may promote Aβ degradation in the liver by modulating the abnormal glucose and lipid metabolisms via the adiponectin-dependent pathway, RXR/PPAR-dependent lipid metabolism signal pathway, and fatty acid synthase activity signal pathway. We also verified whether YXQNW indeed promoted Aβ degradation in hepatic stellate cells. This work provides a novel scientific basis for the mechanism of YXQNW in the treatment of AD.
Background: Coronary artery disease (CAD) exerts a global challenge to public health. Genetic heritability is one of the most vital contributing factors in the pathophysiology of CAD. Co-expression network analysis is an applicable and robust method for the interpretation of biological interaction from microarray data. Previous CAD studies have focused on peripheral blood samples since the processes of CAD may vary from tissue to blood. It is therefore necessary to find biomarkers for CAD in heart tissues; their association also requires further illustration. Materials and Methods: To filter for causal genes, an analysis of microarray expression profiles, GSE12504 and GSE22253, was performed with weighted gene co-expression network analysis (WGCNA). Co-expression modules were constructed after batch effect removal and data normalization. The results showed that 7 co-expression modules with 8,525 genes and 1,210 differentially expressed genes (DEGs) were identified. Furthermore, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted. Four major pathways in CAD tissue and hub genes were addressed in the Hybrid Mouse Diversity Panel (HMDP) and Human Protein Atlas (HPA), and isoproterenol (ISO)/doxycycline (DOX)-induced heart toxicity models were used to validate the hub genes. Lastly, the hub genes and risk variants were verified in the CAD cohort and in genome-wide association studies (GWAS). Results: The results showed that RNF181 and eight other hub genes are perturbed during CAD in heart tissues. Additionally, the expression of RNF181 was validated using RT-PCR and immunohistochemistry (IHC) staining in two cardiotoxicity mouse models. The association was further verified in the CAD patient cohort and in GWAS. Conclusion: Our findings illustrated for the first time that the E3 ubiquitination ligase protein RNF181 may serve as a potential biomarker in CAD, but further in vivo validation is warranted.
Background: Helicobacter pylori (H. pylori) infection is one of the most common chronic bacterial infections worldwide. The resistance of H. pylori to antibiotics may increase the risk of treatment failure. Complementary and alternative regimens are still needed. This study aimed to critically assess the efficacy and safety of Jinghua Weikang capsule (JWC) for H. pylori eradication.Materials and methods: PubMed, Embase, Web of Science, Cochrane library, China National Knowledge Infrastructure, Wanfang Digital Periodicals, and Chinese Science and Technology Periodicals database were searched from inception to April 2022. Randomized controlled trials (RCTs) comparing a combination of JWC and conventional treatments with conventional treatments alone or combined with a placebo for H. pylori eradication were considered for inclusion. The primary outcome was H. pylori eradication rate. The meta-analysis and trial sequential analysis (TSA) were conducted where possible.Results: A total of 34 studies were included in the statistical analysis. A pooled result showed that JWC with the duration of 2 weeks combined with the triple/quadruple therapy could significantly increase the H. pylori eradication rate compared with the triple/quadruple therapy alone (RR: 1.13, 95% CI: 1.05 to 1.21, p = 0.0008). However, the evidence of benefit was not confirmed by TSA. Another pooled result showed that JWC with the duration of 4 weeks combined with the triple/quadruple therapy could significantly increase the H. pylori eradication rate compared with the triple/quadruple therapy alone (RR: 1.21, 95% CI: 1.15 to 1.27, p < 0.00001). The evidence of benefit was confirmed by TSA. There were no statistically significant differences in the incidence of adverse reactions between the two groups.Conclusion: The present study suggests that JWC with the duration of 4 weeks can significantly improve the H. pylori eradication rate and should be considered as a complementary treatment to conventional regimens for H. pylori eradication. However, more high-quality RCTs are still needed to confirm these findings.
Ischemic stroke (IS) is an acute neurological injury that occurs when a vessel supplying blood to the brain is obstructed, which is a leading cause of death and disability. Salvia miltiorrhiza has been used in the treatment of cardiovascular and cerebrovascular diseases for over thousands of years due to its effect activating blood circulation and dissipating blood stasis. However, the herbal preparation is chemically complex and the diversity of potential targets makes difficult to determine its mechanism of action. To gain insight into its mechanism of action, we analyzed “Salvianolic acid for injection” (SAFI), a traditional Chinese herbal medicine with anti-IS effects, using computational systems pharmacology. The potential targets of SAFI, obtained from literature mining and database searches, were compared with IS-associated genes, giving 38 common genes that were related with pathways involved in inflammatory response. This suggests that SAFI might function as an anti-inflammatory agent. Two genes associated with inflammation (PTGS1 and PTGS2), which were inhibited by SAFI, were preliminarily validated in vitro. The results showed that SAFI inhibited PTGS1 and PTGS2 activity in a dose-dependent manner and inhibited the production of prostaglandin E2 induced by lipopolysaccharide in RAW264.7 macrophages and BV-2 microglia. This approach reveals the possible pharmacological mechanism of SAFI acting on IS, and also provides a feasible way to elucidate the mechanism of traditional Chinese medicine (TCM).
Heart failure (HF) is the advanced heart disease with high morbidity and mortality. Compound DanShen Dripping Pill (CDDP) is a widely used Traditional Chinese Medicine for cardiovascular disease treatment. Herein, we investigated if CDDP can protect mice against doxorubicin (DOX) or isoprenaline (ISO)-induced HF. After 3 days feeding of normal chow containing CDDP, mice were started DOX or ISO treatment for 4 weeks or 18 days. At the end of treatment, mice were conducted electrocardiogram and echocardiographic test. Blood and heart samples were determined biochemical parameters, myocardial structure and expression of the related molecules. CDDP normalized DOX/ISO-induced heart weight changes, HF parameters and fibrogenesis. The DOX/ISO-impaired left ventricular ejection fraction and fractional shortening were restored by CDDP. Mechanistically, CDDP blocked DOX/ISO-inhibited expression of antioxidant enzymes and DOX/ISO-induced expression of pro-fibrotic molecules, inflammation and cell apoptosis. Additional DOX/ISO-impaired targets in cardiac function but protected by CDDP were identified by RNAseq, qRT-PCR and Western blot. In addition, CDDP protected cardiomyocytes against oxygen-glucose deprivation-induced injuries. Taken together, our study shows that CDDP can protect against myocardial injuries in different models, suggesting its potential application for HF treatment.
The alterations in vascular homeostasis are deeply involved in the development of numerous diseases, such as coronary heart disease, stroke, and diabetic complications. Changes in blood flow and endothelial permeability caused by vascular dysfunction are the common mechanisms for these three types of diseases. The disorders of glucose and lipid metabolism can bring changes in the energy production patterns in endothelium and surrounding cells which may consequently cause energy metabolic disorders, oxidative stress, and inflammatory responses. Traditional Chinese medicine (TCM) follows the principle of the "treatment by the syndrome differentiation." TCM considers coronary heart disease, stroke, and diabetes complications all as the type of Qi-deficiency and blood stasis syndrome, which mainly occurs in the vascular system. Therefore, the common pathogenesis of these three types of diseases suggests that the treatment strategy by TCM should be in a close manner and referred to as "treating different diseases by the same treatment." Qishen Yiqi dripping pill is a modern Chinese herbal medicine that has been widely used for the treatment of patients with coronary heart disease characterized as Qi-deficiency and blood stasis in China. Recently, many clinical reports have demonstrated the potential therapeutic effects of Qishen Yiqi dripping pills on ischemic stroke and diabetic nephropathy. Based on these reports, we will summarize the clinical applications of Qishen Yiqi dripping pills on coronary heart disease, ischemic stroke, and diabetic nephropathy, including the involved mechanisms discussed in various research works.
