[Research Progress in Niacinamide in the Prevention and Treatment of Mouth and Systemic Diseases].

Nicotinamide (NAM) is the amide form of niacin and one of the precursors of nicotinamide adenine dinucleotide (NAD +). NAM can be used as a dietary supplement or clinical therapeutic drug to replenish NAD + levels in the human body and participate in key bodily functions such as cellular metabolism and DNA repair. NAM has the advantage of low cost, wide availability, and sound biosafety. It also has multiple biological functions, including antibacterial effect, anti-inflammatory effect, and modulation of cellular immunity, producing significant ameliorative effects on skin and neurodegenerative diseases. However, most studies on NAM are still at the laboratory stage. Herein we reviewed the role and mechanism of NAM in the prevention and treatment of oral and systemic diseases, explored its potential as clinical therapeutic medication, provided some basis and references for the clinical application of nicotinamide in the prevention and treatment of various diseases, and discussed its prospects for future research and application.

Expert Consensus on Clinical Diseases Responding Specifically to Traditional Chinese Medicine： Sjögren's Syndrome / 中国实验方剂学杂志

Sjögren's syndrome （SS）， a disorder of immune system， is one of the dominant diseases treated by traditional Chinese medicine （TCM）. China Association of Chinese Medicine organized experts in the field of TCM and western medicine rheumatology and pharmacology to discuss the advantages and optimal regimens of TCM for the treatment of SS. The experts generally agreed on the low early diagnosis rate of SS and the lack of targeted therapeutic drugs. In addition， autoimmune abnormality is the key factor in the occurrence of SS and deficiency of both Qi and Yin is the core pathogenesis. SS has unique tongue manifestations， which is expected to allow for the early diagnosis and treatment with integrated traditional Chinese and western medicine. TCM has advantages in treating SS in terms of alleviating clinical symptoms and systemic involvement， individualized treatment， relieving sleep and mood disorders， preventing the occurrence in the early stage， and enhancing the effectiveness and reducing toxicity in the treatment by integrated TCM and western medicine. In general， TCM has advantages in different stages of SS. Internal and external use of TCM， acupuncture， and acupotome are all available options. The optimal regimens should be determined on the basis of pattern identification， stage of disease， and the advantages of TCM. Clinical characteristics and biomarkers of SS should be studied to classify patients， so as to design precision evidence-based TCM regimens for SS. On the basis of unique tongue manifestations of SS， models for early diagnosis and poor prognosis identification of SS should also be established to achieve early prevention and treatment and to improve the prognosis. In the future， we should vigorously carry out high-quality evidence-based medical research on the treatment of SS by TCM and integrated traditional Chinese and western medicine and develop relevant guidelines to optimize and standardize current diagnosis and treatment， thereby laying a basis for clarifying and explaining the advantages of TCM in treating SS.

Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly (version 2023) / 中华创伤杂志

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Mining intrinsic information of convalescent patients after suffering coronavirus disease 2019 in Wuhan.

OBJECTIVE: To summarize the potential characteristics of convalescent patients with coronavirus disease 2019 (COVID-19) in China based on emerging clinical tongue data and guide the treatment and recovery of COVID-19 patients from the perspective of Traditional Chinese Medicine tongue diagnosis. METHODS: In this study, we developed and validated radiomics-based and lab-based methods as a novel approach to provide individualized pretreatment evaluation by analyzing different features to mine the orderliness behind tongue data of convalescent patients. In addition, this study analyzed the tongue features of convalescent patients from clinical tongue qualitative values, including thick and thin, fur, peeling, fat and lean, tooth marks and cracked, and greasy and putrid fur. RESULTS: We included 2164 tongue images in total (34% from day 0, 35.4% from day 14 and 30.6% from day 28) from convalescent patients. The significance results are shown as follows. Firstly, as the recovery time prolongs, the L average values of tongue and coat decrease from 60.21 to 57.18 and from 60.06 to 57.03 respectively. Secondly, the decrease of abnormality rate of tongue coat, included greasy tongue fur, putrid fur, teeth-mark, thick-thin fur, are of significant statistical difference ( < 0.05). Thirdly, the average value of gray-level co-occurrence matrices increases from 0.173 to 0.194, the average value of entropy increases from 0.606 to 0.665, the average value of inverse difference normalized decrease from 0.981 to 0.979, and the average value of dissimilarity decrease from 0.1576 to 0.1828. The details of other radiomics features are describe in results section. CONCLUSIONS: Our experiment shows that patients in different recovery periods have a relationship with quantitative values of tongue images, including L color space of the tongue and coat radiomics features analysis. This relationship can help clinical doctors master the recovery and health of patients as soon as possible and improve their understanding of the potential mechanisms underlying the dynamic changes and mechanisms underlying COVID-19.

The patients in the observation group were treated with ultrasound-guided EA at suprahyoid muscle group; the patients in the control-1 group were treated with EA at Lianquan (CV 23), Wangu (GB 12) and Fengchi (GB 20), etc.; the patients in the control-2 group were treated with EA at suprahyoid muscle group according to anatomical location. The EA in the three groups were discontinuous wave, with frequency of 5 Hz and current intensity of 1 mA. The EA was given for 30 minutes, once a day, 6 times were taken as a course of treatment, and 4 courses of treatment were provided. The video floroscopic swallowing study (VFSS) was performed before and after treatment. The Rosenbek penetration-aspiration scale (PAS) score, the forward and upward movement distance of hyoid bone and thyroid cartilage, Ichiro Fujima ingestion-swallowing function score were recorded in the three groups, and the incidences of subcutaneous hematoma were recorded after treatment.@*RESULTS@#Compared before treatment, the PAS scores were reduced and the Ichiro Fujima ingestion-swallowing function scores were increased after treatment in the three groups (P<0.05); the PAS scores in the observation group were lower than those in the control-1 group and the control-2 group, and the Ichiro Fujima ingestion-swallowing function scores in the observation group were higher than those in the control-1 group and the control-2 group (P<0.05). After treatment, the forward and upward movement distance of hyoid bone and thyroid cartilage in the observation group and the control-2 group was increased (P<0.05), and the forward and upward movement distance of hyoid bone was increased in the control-1 group (P<0.05); the forward and upward movement distance of hyoid bone and thyroid cartilage in the observation group was longer than that in the control-1 group and the control-2 group (P<0.05). The incidence of subcutaneous hematoma in the observation group was 0% (0/40), which was lower than 20.0% (8/40) in the control-1 group and 47.5% (19/40) in the control-2 group (P<0.05).@*CONCLUSION@#Ultrasound-guided EA at suprahyoid muscle group could improve the swallowing function in patients with pharyngeal dysphagia after stroke by increasing the motion of hyoid laryngeal complex. Its effect and safety are better than conventional acupuncture and conventional EA at suprahyoid muscle group.

Mechanism of Carthami Flos and Lepidii Semen drug pair in inhibition of myocardial fibrosis by improving cardiac microenvironment based on network pharmacology and animal experiment / 中国中药杂志

Previously, Carthami Flos and Lepidii Semen(CF-LS) drug pair has been proved effective in inhibiting myocardial fibrosis(MF) by blunting the activity of cardiac fibroblasts. The present study explored the underlying mechanism of CF-LS in inhibiting MF by improving the cardiac microenvironment based on network pharmacology combined with experimental verification. Active compounds and potential targets of CF-LS were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and the potential targets of MF were obtained from GeneCards, Online Mendelian Inheritance in Man(OMIM), and Pharmacogenetics and Pharmacogenomics Knowledge Base(PharmGKB). The "active component-target-MF" network was constructed and analyzed by Cytoscape 3.8.1. The protein-protein interaction(PPI) network was constructed by STRING. The Gene Ontology(GO) biological process enrichment analysis was performed by CluoGO plug-in. Kyoto Encyclopedia of Genes and Genomes(KEGG) signaling pathway enrichment analysis was performed by R 4.0.2 and Funrich. Subsequently, the inhibitory effect of CF-LS on MF was investigated based on angiotensin Ⅱ(Ang Ⅱ)-induced MF rats. RT-PCR and ELISA were used to verify the effect of CF-LS on the targets of signaling pathways related to vascular endothelial cells predicted by the network pharmacology. Thirty-one active components and 204 potential targets of CF-LS, 4 671 MF-related targets, and 174 common targets were obtained. The network analysis showed that the key targets of CF-LS against MF included RAC-alpha serine/threonine-protein kinase(AKT1), transcription factor AP-1(JUN), mitogen-activated protein kinase 1(MAPK1), cellular tumor antigen p53(TP53), transcription factor p65(RELA), and mitogen-activated protein kinase 8(MAPK8). Biological processes mainly involved regulation of blood vessel diameter, regulation of blood vessel endothelial cell migration, cell death in response to oxidative stress, etc. Advanced glycation end products(AGE)-receptor for advanced glycation end products(RAGE) signaling pathway, phosphoinositide 3-kinase(PI3 K)-serine/threonine protein kinase(AKT) signaling pathway, hypoxia-inducible factor-1(HIF-1) signaling pathway, integrin signaling pathway, transforming growth factor-β(TGF-β) signaling pathway, etc. were involved in signaling pathway enrichment. Literature retrieval confirmed that some of these signaling pathways were closely related to vascular endothelial cells, including AGE-RAGE, PI3 K-AKT, HIF-1α, p53, the transcription factor activator protein-1(AP-1), integrin, p38 MAPK, and TGF-β. Animal experiments showed that CF-LS inhibited MF induced by Ang Ⅱ in rats by suppressing the expression of RAGE, HIF-1α, integrin β6, and TGF-β1. The inhibitory effect of CF-LS on MF has the characteristics of multiple components, multiple targets, and multiple pathways. CF-LS can inhibit MF by regulating the activity of vascular endothelial cells in the cardiac microenvironment.

Mechanism of Baihe Dihuangtang in Treatment of Depression with Yin Deficiency and Internal Heat / 中国实验方剂学杂志

ObjectiveTo establish a traditional Chinese medicine （TCM） syndrome model with yin deficiency and internal heat， discuss the rationality of model evaluation， and analyze differentially expressed genes in multiple dimensions to explore the molecular mechanism-signaling pathways as well as key targets of Baihe Dihuangtang （BHDH） in treating depression with Yin deficiency and internal heat. MethodForty male SD rats were randomly divided into a blank control group，a model group，a fluoxetine group （positive drug），a BHDH group， and a Zhibai Dihuangtang group （positive drug for Yin deficiency and internal heat）. The depression model with Yin deficiency and internal heat was induced by chronic unpredictable mild stress （CUMS）combined with Chinese herbal drugs with warm and heat nature. The model established was comprehensively evaluated by the detection of the basic condition， behavioral performance， and biochemical indicators of rats in each group. The differentially expressed genes were screened out by mRNA sequencing and underwent Gene Ontology（GO） and Kyoto Encyclopedia of Genes and Genomes（KEGG） pathway enrichment analyses. The protein-protein interaction （PPI） network was plotted and key genes were analyzed to explore the underlying mechanism of BHDH in treating depression with Yin deficiency and internal heat. ResultThe comparison of basic conditions， behavioral assays， energy metabolism， endocrine hormones， cytokines， and neurotransmitters showed that the model was properly induced. BHDH could significantly improve depression with Yin deficiency and internal heat by regulating the pathways related to the nervous system， endocrine system， and inflammatory and immune system. The key genes of the PPI network were Fos， Epha8， Npy2r， Htr2c， and Nr4a1. ConclusionUnder the guidance of TCM theories of treatment based on syndrome differentiation and etiology and pathogenesis，this study established a depression model with yin deficiency and internal heat in animals and evaluation system in accordance with the symptoms and signs of emotional diseases， and further confirmed the scientificity of the modeling method and the underlying mechanism of BHDH in interfering with depression with Yin deficiency and internal heat based on the results of mRNA sequencing.

Consensus on collaborative ethical review of multi-center clinical trials of new drugs of traditional Chinese medicine (version 1.0) / 中国中药杂志

At present, the issues regarding multi-center clinical trials of new drugs of traditional Chinese medicine(TCM) remain: the lack of agreement on the content and scope of the ethical review among the ethics committee members of the center and the participating units results in repeated review, which leads to a time-consuming ethical review process. Moreover, the review capabilities of the ethics committees of various research centers are uneven, which is not necessarily beneficial to the protection of subjects' rights and safety. In view of the existing problems, to improve the efficiency of ethical review of multi-center clinical trials of new drugs of TCM and avoid repeated reviews, the TCM Clinical Evaluation Professional Committee of Chinese Pharmaceutical Association organized experts to formulate the "Consensus on collaborative ethical review of multi-center clinical trials of new drugs of TCM(version 1.0)"(hereinafter referred to as "Consensus"). The "Consensus" is formulated in accordance with the requirements of relevant documents such as but not limited to "the opinions on deepening the reform of the evaluation and approval system to encourage the innovation of pharmaceutical medical devices", "the regulations of ethical review of biomedical research involving human subjects". The "Consensus" covers the scope of application, formulation principles, conditions for the ethics committee of the center, sharing of ethical review resources, scope and procedure of collaborative review, rights and obligations, etc. The aims of the "Consensus" is to preliminarily explore and establish a scientific and operable ethical review procedure. Additionally, on the basis of fully protecting the rights and interests of the subjects, a collaborative ethical review agreement needs to be signed to clarify the ethical review responsibilities of all parties, to avoid repeated review, and to improve the efficiency and quality of ethical review in multi-center clinical trials of new drugs of TCM.

Investigation of Potential Pharmacodynamic Substances and Mechanism of Gardeniae Fructus in Treatment of Ischemic Stroke Based on HPLC-Q-TOF-MS/MS and Network Pharmacology / 中国实验方剂学杂志

Objective:Combined with high performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry （HPLC-Q-TOF-MS/MS） and network pharmacology， to predict the target and potential mechanism of Gardeniae Fructus in the treatment of cerebral ischemia. Method:HPLC-Q-TOF-MS/MS was used to identify the chemical constituents of Gardeniae Fructus according to the retention time， relative molecular weight， secondary mass spectrometry fragmentation and other information of chromatographic peaks， and combined with literature data. The targets of main active ingredients in Gardeniae Fructus were predicted by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and SwissTargetPrediction database. The potential targets of Gardeniae Fructus against cerebral ischemia were obtained through Online Mendelian Inheritance in Man （OMIM）， GeneCards and Kyoto Encyclopedia of Genes and Genomes （KEGG）. Gene ontology （GO） function enrichment and KEGG pathway analysis of potential targets were analyzed with the DAVID 6.8. Cytoscape 3.6.0 software was used to construct the network of active components-targets-pathways. At last， Discovery Studio 2016 software was applied in the molecular docking verification between the key active ingredients and potential protein targets. Result:A total of 40 chemical constituents in Gardeniae Fructus were identified， including iridoids， diterpenoid pigments， organic acids， monoterpenoids and other components. According to the main active ingredients， 208 potential targets were predicted， 560 disease targets related to cerebral ischemia were retrieved， 59 key targets were selected by mapping component targets with disease targets. These targets could act on key target proteins such as tumor necrosis factor （TNF）， Caspase-3 （CASP3） and CASP8， and participate in the regulation of TNF， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， hypoxia inducible factor 1 （HIF-1） and other signal pathways. Molecular docking results showed that geniposide could interact with targets of prostaglandin G/H synthase 2 （PTGS2）， TNF<italic> </italic>and nuclear transcription factor-<italic>κ</italic>B p65 （RELA）， crocin Ⅰ could interact with interleukin-2 （IL-2）. Conclusion:Geniposide， crocin Ⅰ and other ingredients in Gardeniae Fructus can play a role of anti-inflammatory and inhibiting apoptosis to prevent or treat cerebral ischemic diseases by up-regulating protein expression level of RELA and IL-2， down-regulating protein expression level of TNF， CASP8， CASP3 and matrix metalloproteinase 2 （MMP2）， and regulating TNF， PI3K/Akt and HIF-1 signaling pathways.

There were 5 males and 23 females, with median age 63.00 (47.50, 66.75) years old. The urgency score was 4 (3, 4) points, 24-hour micturition frequency was 26 (20.50, 32.50) times, nocturia was 9 (7, 12) times, single urine volume was 59.00 (41.25, 79.50) ml, VAS score was 9.0 (8.0, 9.0) points, O′Leary-Sant score was 31.00 (20.25, 33.00) points, and single maximum urine volume was 100.0 (80.0, 127.5) ml. The improvement of symptoms before operation, test period and last follow-up were compared.Results:The urgency score was 2 (1, 3), the 24-hour micturition frequency was 17.00 (15.00, 22.75), the frequency of nocturia was 5.5 (4.0, 7.0), the single urine volume was 87.50 (70.25, 110.00) ml, the VAS score was 4.0 (3.0, 6.0) and the O′Leary-Sant score was 20.00 (17.00, 23.00) in 28 patients during the test period, which were significantly improved compared with those before operation ( P < 0.05). There was no significant difference in the single maximum urine volume of 135.0 (102.5, 160.0) ml between the two groups ( P > 0.05). 28 patients received SNM Ⅱ permanent stimulator implantation. The median follow-up time was 29.5 (21.25, 61.75) months. Among the 28 patients, 3 patients underwent cystectomy and ileal conduit after removal of the complete SNM system due to the unsatisfied results. Twenty-five cases (89.3%) were still treated with SNM. Among them, 6 cases accepted combinative therapy of oral medicine (antihistamines, sodium pentose polysulfate, hormones, immunosuppressants, etc.). Two cases accepted combinative therapy of intravesical instillation, including heparin in one case and sodium hyaluronate in the other one. Three cases accepted combinative therapy of botulinum toxin injection.One case accepted combinative therapy of bladder augmentation. Two cases accepted combinative therapy of traditional Chinese medicine (TCM). One case accepted combinative therapy of oral medicine and TCM. The remaining 10 cases didn't accept any treatment. Among them, 3 cases were still treated with SNM even though they were not satisfied with the effect, including 1 case due to electrode displacement. At the last follow-up of 25 patients, the urgency score was 2 (1, 3), the 24-hour micturition frequency was 16.50 (13.00, 19.75), the frequency of nocturia was 5.5 (4.0, 9.0), the single urine volume was 105.0 (72.5, 120.0) ml, the VAS score was 4.5 (3.0, 6.0) and the O'Leary Sant score was 16.00 (14.00, 22.50), which were significantly improved compared with those before operation ( P < 0.05), but no difference with those during test period ( P>0.05). There was no significant difference in the single maximum urine volume of 125.0 (102.5, 150.0) ml at the last follow-up compared with preoperative and test period ( P>0.05). Conclusions:As a treatment option for refractory IC / BPS, SNM can improve the symptoms of most patients and maintain good long-term efficacy combined with other.

Novel and potent inhibitors targeting DHODH are broad-spectrum antivirals against RNA viruses including newly-emerged coronavirus SARS-CoV-2

Emerging and re-emerging RNA viruses occasionally cause epidemics and pandemics worldwide, such as the on-going outbreak of the novel coronavirus SARS-CoV-2. Herein, we identified two potent inhibitors of human DHODH, S312 and S416, with favorable drug-likeness and pharmacokinetic profiles, which all showed broad-spectrum antiviral effects against various RNA viruses, including influenza A virus, Zika virus, Ebola virus, and particularly against SARS-CoV-2. Notably, S416 is reported to be the most potent inhibitor so far with an EC of 17 nmol/L and an SI value of 10,505.88 in infected cells. Our results are the first to validate that DHODH is an attractive host target through high antiviral efficacy in vivo and low virus replication in DHODH knock-out cells. This work demonstrates that both S312/S416 and old drugs (Leflunomide/Teriflunomide) with dual actions of antiviral and immuno-regulation may have clinical potentials to cure SARS-CoV-2 or other RNA viruses circulating worldwide, no matter such viruses are mutated or not.

Correlation analysis of color change and Maillard reaction during processing of Gardeniae Fructus Praeparatus / 中国中药杂志

The chromaticity space parameters of the samples during the processing of Gardeniae Fructus Praeparatus(Jiaozhizi in Chinese herbal name, JZZ) were measured by the visual analyzer to analyze the color variation rule during the processing of JZZ, and the content changes of total reducing sugar, total amino acid and 5-hydroxymethylfurfural(5-HMF) related to Maillard reaction were measured. Pearson correlation analysis and linear regression analysis of the data were carried out by SPSS 24.0 software. The experimental results showed that the objective coloration of the samples in the processing of JZZ was basically consistent with the traditional subjective color judgment; the contents of total reducing sugar and total amino acids showed a decreasing trend during the processing of JZZ, and the content of 5-HMF showed an increasing trend, which was in line with Maillard reaction law. Pearson correlation analysis results showed that there was a significant correlation between the chromaticity space parameters L~*(lightness value), a~*(red green value), b~*(yellow blue value), E~*ab(total color value) and the contents of total reducing sugar, total amino acid and 5-HMF(P<0.01), among which the values of L~*, a~*, b~*, E~*ab were positively correlated with the contents of total reducing sugar and total amino acid, and negatively correlated with the contents of 5-HMF. The results of linear regression analysis also showed that these two were highly correlated. In this study, by establishing the correspondence relationship between the color change of JZZ processing and Maillard reactants, wecan not only provide a basis for the objective digital expression of subjective color of JZZ, but also provide a reference for explaining the processing mechanism of JZZ from a new perspective.

Study on the effectiveness of an information system on the prevention and control of venous thromboembolism in elderly inpatients / 中华老年医学杂志

Objective:To explore the effectiveness of an information system on the prevention and control of venous thromboembolism(VTE)in elderly inpatients.Methods:Through retrospectively reviewing medical records of Beijing Shijitan Hospital and files of all patients admitted to the geriatric department of our hospital before and after an information management system was instituted, data of those diagnosed with deep venous thrombosis of the lower extremities, intermuscular venous thrombosis and/or pulmonary thromboembolism(PE)at discharge were collected.General information, prognosis of disease, risk factors for VTE, the detection rate and assessment rate of VTE and other factors were analyzed.Methods:A total of 146 patients were enrolled, and they were mainly elderly patients from the respiratory, cardiology and integrative medicine wards.Diabetes mellitus, cancer and chronic heart failure were the top-three high-risk diseases, and most patients were at high risk or very high risk.The rate of elderly patients assessed as at high risk for VTE on admission was higher after the institution of the information system than that before the institution(93.22% vs.24.66%, P<0.05). The rate of VTE patients receiving standard diagnosis and anticoagulant treatment procedures had an upward trend since the information system became available, compared with before(8.47% vs.5.48%, P>0.05). There was a downward trend in the incidence of PE and all-cause mortality with the use of the information system(3.39% vs.9.59%, 5.08% vs.9.59%, P>0.05). Conclusions:The use of information systems can effectively increase the risk assessment rate for VTE and reduce the incidence of related adverse events in hospitalized elderly patients.

The mechanism of Danqi tablets in the treatment of coronary heart disease based on network pharmacology / 药学学报

We used the network pharmacology to explore the active ingredients and mechanism of action of Danqi tablets in the treatment of coronary heart disease, providing a theoretical basis for the treatment of clinical coronary heart disease. The TCMSP database was used to screen for active ingredients and targets in Danqi tablets; the predicted targets of coronary heart disease were screened through the GeneCards database; then, the intersection of the two targets was mapped; we used STRING database to construct a protein interaction network map and identified 65 cores targets; then, the DAVID database was used for enrichment analysis of gene ontology (GO) biological processes and KEGG signaling pathways, and finally the Cytoscape-3.6.2 software was used to construct a network diagram of traditional Chinese medicine-active ingredient-key targets-pathway. The H2O2-induced H9C2 cells injury model was used for experimental verification. The results suggest that Danqi tablets act on inflammatory factors and apoptosis-related pathways through quercetin, luteolin, tanshinone IIA, and other active ingredients, and improve proinflammatory or anti-inflammatory imbalances in the body and protect cardiomyocytes. This study confirms the multi-component and multi-target effects of Danqi tablets in the treatment of coronary heart disease, and provides an objective basis for their use in further experimental research and the clinical diagnosis and treatment of coronary heart disease.
