Comparison of clinical effects of coronary artery bypass grafting between left anterior small thoracotomy approach and lower-end sternal splitting approach.

OBJECTIVE: To compare the clinical effects of coronary artery bypass grafting (CABG) between the left anterior small thoracotomy (LAST) and lower-end sternal splitting (LESS) approaches for coronary artery disease. METHODS: In total, 110 patients who underwent LAST from October 2015 to December 2020 in Tianjin Chest Hospital were selected as the observation group. Patients who underwent the LESS approach during the same period were analyzed. The propensity score was calculated by a logistic regression model, and nearest-neighbor matching was used for 1:1 matching. RESULTS: The length of hospital stay and ventilator support time were significantly shorter in the LAST than LESS group. The target vessels in the obtuse marginal branch and posterior left ventricular artery branch grafts were significantly more numerous in the LAST than LESS group, but those in the right coronary artery graft were significantly less numerous in the LAST group. CONCLUSIONS: CABG using either the LAST or LESS approach is safe and effective, especially in low-risk patients. The LAST approach can achieve complete revascularization for multivessel lesions and has the advantages of less trauma and an aesthetic outcome. However, it requires a certain learning curve to master the surgical techniques and has specific surgical indications.

Evaluating spray drift from Uncrewed Aerial Spray Systems: A machine learning and variance-based sensitivity analysis of environmental and spray system parameters.

Uncrewed Aerial Spray Systems (UASS), commonly called drones, have become an important application technique for plant protection products in Asia and worldwide. As such, environmental variables and spray system parameters influencing spray drift deserve detailed investigations. This study presents the data analysis of 114 UASS drift trials conducted between December 2021 and December 2022 in China. Study design was based on the ISO 22866:2005 protocol for spray drift trials and considered different UASS platforms, nozzles, and release heights, and specifically continuously measured weather conditions. The relative importance of the environmental variables and spray system parameters was evaluated by a random forest (RF) feature importance analysis, a Sobol sensitivity analysis and partial dependence plots. This approach was preferred to linear ranking techniques such as ANOVA (analysis of variance) due to the non-linearity of the system. In addition, partial dependence plots are proposed to visualize the relationship between specific input parameters within the system. Drift deposition curves calculated from the 114 trials show good agreement with previous UASS trials reported in the literature. As reported in previous studies, spray drift following UASS applications is lower than for manned aerial vehicles, greater than for ground spray applications, and similar to drift observed from orchard air blast applications. In addition, 9 trials were conducted on corn fields in order to evaluate the potential effect of crop cover on spray drift. Spray drift was observed to be reduced over the cropped soil, suggesting that plant cover might possibly reduce spray drift. These findings could help supporting drift mitigation policies, stewardship advice and product labelling around the world.

Palladium/norbornene-catalyzed diversified trifunctionalization of aryl-thianthreniums.

A novel Catellani-type conversion is reported using aryl-thianthreniums (aryl-TTs) instead of aryl halides. Three classes of ortho-dual C-H functionalization involving alkylation, amination, and deuterated methylation and five types of ipso-operation including alkenylation, cyanation, methylation, hydrogenation, and alkynylation all proceed well in this procedure. In this conversion, aryl-TTs exhibit satisfactory reactivity and feature the advantage that the leaving TT unit can be recovered. More strikingly, this finding represents a new chemistry conversion of aryl-TTs, wherein contiguous tri-functionalization in a single chemical manipulation is realized.

Experience of Older Patients with COPD Using Disease Management Apps: A Qualitative Study.

(1) Background: Digital medicine is developing in the management of chronic diseases in older people, but there is still a lack of information on the use of disease management apps in older patients with COPD. This study aims to explore the views and experience of older patients with COPD on disease management apps to provide a basis for the development and promotion of apps for geriatric diseases. (2) Methods: A descriptive qualitative research method was used. Older patients with COPD (N = 32) with experience using disease management apps participated in semi-structured interviews. Thematic analysis was used to analyze the data. (3) Results: Seven themes were defined: (a) feeling curious and worried when facing disease management apps for the first time; (b) actively overcoming barriers to use; (c) gradually becoming independent by continuous online learning; (d) feeling safe in the virtual environment; (e) gradually feeling new value in online interactions; (f) relying on disease management apps under long-term use; (g) expecting disease management apps to meet personalized needs. (4) Conclusions: The adoption and use of disease management apps by older people is a gradual process of acceptance, and they can obtain a wide range of benefits in health and life.

Fall risk perception in older adults: A concept analysis.

BACKGROUND: Fall prevention is crucial for older adults. Enhanced fall risk perception can encourage older adults to participate in fall prevention programs. However, there is still no unified definition of the concept of fall risk perception. OBJECTIVE: To explore the concept of fall risk perception in older adults. DESIGN: A concept analysis. DATA SOURCES: The literature was searched using online databases including PubMed, Cochrane Library, Embase, CINAHL Complete, PsycINFO, Web of Science, China National Knowledge Infrastructure, WangFang and SinoMed. Searches were also conducted in Chinese and English dictionaries. The literature dates from the establishment of the database to April 2023. METHODS: The methods of Walker and Avant were used to identify antecedents, attributes and consequences of the concept of "fall risk perception" in older adults. RESULTS: Eighteen publications were included eventually. The attributes were identified as: (1) dynamic change, with features of continuum and stage; (2) whether falls are taken seriously; (3) a self-assessment of the fall probability, which is driven by individual independence; and (4) involves multiple complex emotional responses. The antecedents were identified as: (1) demographic and disease factors; (2) psychological factors and (3) environmental factors. The consequences were identified as: (1) risk-taking behaviour; (2) risk compensation behaviour; (3) risk transfer behaviour; and (4) emotions. CONCLUSION: A theoretical definition of fall risk perception was identified. A conceptual model was developed to demonstrate the theoretical relationships between antecedents, attributes and consequences. This is helpful for the development of relevant theories and the formulation of fall prevention measures based on fall risk perception as the intervention target.

Palladium-Catalyzed Domino Conversion of Aryl-Thianthreniums with Anhydrides: Rapidly Building Highly Functionalized Fluorenones.

As a class of rising electrophilic coupling reagents, aryl-thianthreniums (aryl-TTs) have been gaining immense attention. Herein, a novel palladium-catalyzed domino annulation of aryl-TTs with anhydrides is proposed to rapidly assemble a collection of highly functionalized fluorenones. This finding presents an innovative reaction pattern of aryl-TTs wherein the domino annulation version is first involved. Heavily compared with the existing conversions with aryl-TTs, this identified process successively functions as four aryl C-H bonds.

Palladium-catalyzed denitrogenation/vinylation of benzotriazinones with vinylene carbonate.

Herein, a novel Pd-catalyzed denitrogenation/vinylation of benzotriazinones using vinylene carbonate as the vinylation reagent is reported. This transformation demonstrates an unprecedented skeletal editing approach, effectively converting NN to CC fragments in situ and synthesizing a collection of isoquinolinones with broad-spectrum functional group tolerance. Moreover, the quite concise reaction system and late-stage modification of bioactive molecules comprehensively underscore the practical potential of this protocol.

Factors Associated with the e-Health Literacy Among Older Adults with Chronic Obstructive Pulmonary Disease: A Cross-Sectional Study.

Background: The telemanagement model in chronic diseases needs older patients to have a certain level of e-Health literacy. According to Electronic Health Literacy model, factors associated with the e-Health literacy among older patients could be comprehensively investigated from individual, situational, and environmental aspects. Objectives: To investigate the e-Health literacy levels among older patients with chronic obstructive pulmonary disease (COPD) and explore associated factors. Methods: A cross-sectional study was conducted among older patients with COPD. The e-Health Literacy Scale was used to measure individuals' e-Health literacy. The multiple linear regression was applied to identify factors associated with e-Health literacy. Results: A total of 230 responses were included in the final analysis. The average score of e-Health literacy for older COPD patients was 24.66 (6.86). After adjusting the model, the results of multiple linear regression demonstrated that aging attitudes (B = 0.067, p < 0.001), technophobia (B = -0.285, p < 0.001), and self-efficacy (B = 0.431, p < 0.001) accounted for 68.3% (p < 0.001) of the total variation in e-Health literacy. Conclusion: This study identifies significant correlations of technophobia, aging attitudes, and self-efficacy, respectively, with e-Health literacy, and self-efficacy and technophobia may be constant predictive factors of e-Health literacy. In the future, intervention research on e-Health literacy should be conducted from a social psychology perspective, with particular emphasis on addressing negative aging attitudes and technophobia. That will promote the tele-management model of chronic diseases. Trial Registration: Chinese Clinical Trial Registry (ChiCTR): ChiCTR1900028563; http://apps.who.int/trialsearch/default.aspx.

Factors associated with the core dimensions of spiritual health among older adults with chronic obstructive pulmonary disease: A cross-sectional study.

AIMS: To investigate the level of spiritual health in older patients with chronic obstructive pulmonary disease (COPD) from the core dimensions and to explore its associated factors. DESIGN: A cross-sectional study. METHODS: Participants were recruited from four hospitals between September 2020 and June 2021, using a convenience sampling. Older patients with COPD (n = 162) completed the demographic and disease-related information questionnaires, Function Assessment of Chronic Illness Therapy Spiritual Scale, 10-item Connor-Davidson Resilience Scale, General Self-efficacy Scale, Social Support Rating Scale, COPD Assessment Test, 15-item Geriatric Depression Scale and modified Medical Research Council Dyspnea Scale. Descriptive statistics, Pearson and Spearman correlation analyses, t-tests, one-way ANOVA and multiple linear regression models were used. RESULTS: Older patients with COPD have a moderate level of spiritual health. The multiple linear regression analysis showed that psychological resilience, general self-efficacy, social support, symptom burden and monthly income were associated with the core dimensions of spiritual health. CONCLUSION: Chinese older patients with COPD have a moderate level of spiritual health. Psychological resilience, general self-efficacy, social support, monthly income and symptom burden were associated with the core dimensions of spiritual health. IMPACT: This study is the first to investigate the level of spiritual health in older patients with COPD from the core dimensions and to explore its associated factors, providing a basis for developing spiritual intervention programs. Our findings can help us realize that intervention strategies of psychological resilience, general self-efficacy and social support can all be used to enhance spiritual health. Nurses should focus on the spiritual health of older COPD patients with high symptom burden and low monthly income. PATIENT OR PUBLIC CONTRIBUTION: Although we did not directly involve patients and the public because of the COVID-19 pandemic, the results of the study will be disseminated to patients and the public through WeChat and seminars.

Crosslinking strategies of decellularized extracellular matrix in tissue regeneration.

By removing the immunogenic cellular components through various decellularization methods, decellularized extracellular matrix (dECM) is considered a promising material in the field of tissue engineering and regenerative medicine with highly preserved physicochemical properties and superior biocompatibility. However, decellularization treatment can lead to some loss of structural integrity, mechanical strength, degradation stability, and biological performance of dECM biomaterials. Therefore, physical and chemical crosslinking methods are preferred to restore or even improve the biomechanical properties, stability, and bioactivity, and to achieve a delicate balance between degradation of the implanted biomaterial and regeneration of the host tissue. This review provides an overview of dECM biomaterials, and describes and compares the mechanisms and characteristics of commonly used crosslinking methods for dECM, with a focus on the potential applications of versatile dECM-based biomaterials derived from skin, cardiac tissues (pericardium, heart valves, myocardial tissue), blood vessels, liver, and kidney, modified with different chemical crosslinking reagents, in tissue and organ regeneration.

Rhodium-catalyzed divergent dehydroxylation/alkenylation of hydroxyisoindolinones with vinylene carbonate.

Herein, a novel organic transformation involving rhodium-catalyzed divergent dehydroxylation/alkenylation of hydroxyisoindolinone with vinylene carbonate is reported, and a series of architecturally rigid and widely used spirolactams are obtained with excellent functional group tolerance and high selectivity. Remarkably, the promising vinylene carbonate reagent presents a distinct chemical reactivity as a vinyl-oxygen cyclic synthon and first transfers the C-H bond to spiroheterocycle scaffolds. Moreover, another chemoselectivity, direct dehydrogenative coupling with vinylene carbonate, is also presented. This protocol is compatible with green chemistry and only releases H2O and CO2 as byproducts.

In(OTf)3-catalyzed reorganization/cycloaddition of two imine units and subsequent modular assembly of acridinium photocatalysts.

Herein, we disclose a novel reorganization/cycloaddition between two imine units catalyzed by In(OTf)3 Lewis acid that differs from the well-known [4 + 2] cycloaddition version via the Povarov reaction. By means of this unprecedented imine chemistry, a collection of synthetically useful dihydroacridines has been synthesized. Notably, the obtained products give rise to a series of structurally novel and fine-tuneable acridinium photocatalysts, offering a heuristic paradigm for synthesis and efficiently facilitating several encouraging dihydrogen coupling reactions.

Patient Experiences and Perspectives of Their Decision-Making to Accept Lung Transplantation Referral: A Qualitative Study.

Providing early lung transplantation referral services should be considered to reduce pre-transplant mortality in patients with advanced disease. This study aimed to explore the reasons for lung transplantation referral decisions in patients and provide evidence for the development of transplantation referral services. This was a qualitative, retrospective, and descriptive study involving conventional content analysis. Patients in evaluation, listing, and post-transplant stages were interviewed. A total of 35 participants (25 male and 10 female) were interviewed. Four main themes were defined: (1) expectations for lung transplantation leading to the decision (a gamble for a silver lining, a return to normal life, and occupation); (2) facing uncertain outcomes (personal luck arranging everything; belief in success; incidents leading to "It's decided then"; hesitation when making a decision due to fear); (3) facing various information from peers, doctors, and so on; (4) complex policy and societal support (providing transplantation referral services earlier, family attachment and oral approval responses contribute to the referral decision, and so on). The findings of this study might enrich existing referral services, including training for family members and healthcare providers, a checklist and package of critical events in the patient lung transplantation referral decision-making process, precision services based on behavioral personas, and a curriculum to enhance patient decision self-efficacy.

Hypervalent iodine-promoted twofold oxidative coupling of amines with amides and thioamides: chemoselective pathway to oxazoles and thiazoles.

Direct functionalization of the C(O)-N amide bond is one of the most high-profile research directions in the last few decades; however oxidative couplings involving amide bonds and functionalization of thioamide C(S)-N analogues remain an unsolved challenge. Herein, a novel hypervalent iodine-induced twofold oxidative coupling of amines with amides and thioamides has been established. The protocol accomplishes divergent C(O)-N and C(S)-N disconnection by the previously unknown Ar-O and Ar-S oxidative coupling and highly chemoselectively assembles the versatile yet synthetically challenging oxazoles and thiazoles. Employing amides instead of thioamides affords an alternative bond cleavage pattern, which is a result of the higher conjugation in thioamides. Mechanistic investigations indicate ureas and thioureas generated in the first oxidation as pivotal intermediates to realize the oxidative coupling. These findings open up new avenues for exploring oxidative amide and thioamide bond chemistry in various synthetic contexts.

Surface-based morphometry study of brain in patients with carbon monoxide poisoning.

PURPOSE: Although cortical volume abnormalities are frequently detected in patients with carbon monoxide poisoning (COP), particularly delayed neurological sequelae (DNS), the associated changes in cortical thickness and shape patterns remain unknown. MATERIALS & METHODS: Using surface-based morphometry, we investigated the differences in cortical thickness and shape indices between a COP group (n = 44) vs healthy controls (HCs, n = 36), and between the DNS (n = 21) vs non-DNS (n = 23) subgroups. Additionally, the influence of cortical damage on neurological disorders was explored. RESULTS: The COP group exhibited significant cortical thinning mainly in the bilateral fronto-parietal lobes (P < 0.05, family-wise error corrected). When cortical thinning in the bilateral parietal lobes, bilateral primary motor areas, left primary sensory areas, and bilateral paracentral lobules was explored in the DNS subgroups compared to the non-DNS subgroup (P < 0.05, FWE corrected), no differences in shape indices between the two subgroups were noted. In the COP group, there were significant positive correlations between the Mini-Mental State Examination (MMSE) score and cortical thickness in the right superior frontal gyrus (SFG) and bilateral rostral middle frontal gyrus (rMFG) (P < 0.05, false discovery rate corrected). There was no any significant correlation between cortical thickness and Neuropsychiatric inventory (NPI), UPDRS III scores (P > 0.05, FDR-corrected). CONCLUSION: Cortical thickness is a more sensitive index than shape for measuring cortical damage in patients with COP exposure, as cortical thinning in the right SFG and bilateral rMFG is related to cognitive impairment.

Trajectory of suicidal ideation among medical students during the COVID-19 pandemic: the role of childhood trauma.

BACKGROUND: The aim of this study was to understand the longitudinal trajectory of suicidal ideation (SI) among Chinese medical students and the role of childhood trauma (CT). METHODS: Using a whole-group sampling method, we assessed SI in 2192 (male = 834, female = 1358) medical students on three occasions over a period of one year. The Suicidal Ideation Self-Assessment Scale (SISAS) and the Childhood Trauma Questionnaire-Short Form (CTQ-SF) were used to assess SI and CT. The growth mixture modeling (GMM) was used to classify the developmental trajectory of SI. RESULTS: A greater number of medical students were experiencing suicidal ideation during the COVID-19 pandemic. The trajectory of SI among medical students was divided into two groups: a low risk, slowly rising group and a high risk, continuous group. The low risk, slowly rising group had a significant time effect (B = 1.57, p < 0.001) and showed a slowly increasing trend. Emotional neglect (EN), physical neglect (PN), emotional abuse (EA) and physical abuse (PA) all had significant positive predictive effects for the high risk, continuous group (B = 0.18-0.65, P < 0.01). CONCLUSION: The trajectory of SI among medical students can be divided into a low risk, slowly rising group and a high risk, continuous group; the more EN, PN, EA and PA experienced during childhood, the more likely medical students are to develop a high risk, continuous state of SI.

Evaluation of Efficacy and Prognosis Analysis of Stage III-IV SMARCA4-deficient Non-small Cell Lung Cancer Treated by PD-1 Immune Checkpoint Inhibitors plus Chemotherapy and Chemotherapy / 中国肺癌杂志

BACKGROUND@#The SMARCA4 mutation has been shown to account for at least 10% of non-small cell lung cancer (NSCLC). In the present, conventional radiotherapy and targeted therapy are difficult to improve outcomes due to the highly aggressive and refractory nature of SMARCA4-deficient NSCLC (SMARCA4-DNSCLC) and the absence of sensitive site mutations for targeted drug therapy, and chemotherapy combined with or without immunotherapy is the main treatment. Effective SMARCA4-DNSCLC therapeutic options, however, are still debatable. Our study aimed to investigate the efficacy and prognosis of programmed cell death 1 (PD-1) immune checkpoint inhibitors (ICIs) in combination with chemotherapy and chemotherapy in patients with stage III-IV SMARCA4-DNSCLC.@*METHODS@#46 patients with stage III-IV SMARCA4-DNSCLC were divided into two groups based on their treatment regimen: the chemotherapy group and the PD-1 ICIs plus chemotherapy group, and their clinical data were retrospectively analyzed. Efficacy assessment and survival analysis were performed in both groups, and the influencing factors for prognosis were explored for patients with SMARCA4-DNSCLC.@*RESULTS@#Male smokers are more likely to develop SMARCA4-DNSCLC. There was no significant difference in the objective response rate (76.5% vs 69.0%, P=0.836) between chemotherapy and the PD-1 ICIs plus chemotherapy or the disease control rate (100.0% vs 89.7%, P=0.286). The one-year overall survival rate in the group with PD-1 ICIs plus chemotherapy was 62.7%, and that of the chemotherapy group was 46.0%. The difference in median progression-free survival (PFS) between the PD-1 ICIs plus chemotherapy group and the chemotherapy group was statistically significant (9.3 mon vs 6.1 mon, P=0.048). The results of Cox regression analysis showed that treatment regimen and smoking history were independent influencing factors of PFS in patients with stage III-IV SMARCA4-DNSCLC, and family history was an individual influencing factor of overall survival in patients with stage III-IV SMARCA4-DNSCLC.@*CONCLUSIONS@#Treatment regimen may be a prognostic factor for patients with SMARCA4-DNSCLC, and patients with PD-1 ICIs plus chemotherapy may have a better prognosis.

Devascularized bone surface culture for identification of microorganisms for osteomyelitis / 中华创伤骨科杂志

Objective:To evaluate devascularized bone surface culture for identification of microorganisms for osteomyelitis.Methods:A prospective study was conducted to include the eligible patients who were diagnosed with osteomyelitis and treated at Division of Orthopaedics and Traumatology, Department of Orthopaedics and Traumatology, Nanfang Hospital from December 2021 to January 2023. Their infected bone tissues were collected for both bone sample culture (BSC) and general sample culture (GSC). For BSC, the devascularized bone fragments, harvested intraoperatively, were put flat on sterile culture plates with solidified agar, their surface was gently covered with cooled and molten tryptone soy agar, and then the plates with bone samples were incubated at 37 ℃ with 5% CO 2. Meanwhile, 5 suspected samples of infected bone tissue were randomly harvested by 5 independent instruments for laboratory GSC. The culture time, bacterial species, and bacterial positive rate were compared between the 2 culture methods. Results:Included were a total of 73 patients [59 males and 14 females with an age of 49.0(31.0, 58.5) years]. The culture time for BSC [1 (1, 1) d] was significantly shorter than that for GSC [3 (2, 3) d], and the total positive rate of BSC [78.1% (57/73)] was significantly higher than that of GSC [61.6% (45/73)] ( P<0.05). The bacterial species cultured by GSC were consistent with those cultured by BSC. Conclusion:In identification of microorganisms for osteomyelitis, since BSC may be quicker and lead to a higher positive rate of bacterial culture than GSC, it can be used as an optional choice besides GCS.

Efficacy of implant surface culture in identification of microorganisms for fracture device-related infection: a preliminary analysis / 中华创伤骨科杂志

Objective:To evaluate the efficacy of implant surface culture in identification of pathogens for fracture device-related infection.Methods:A prospective study was conducted to include the eligible patients who were diagnosed with infection after fracture fixation and needed surgical removal of the implants according to treatment principles at Division of Orthopaedics and Traumatology, Department of Orthopaedics and Traumatology, Nanfang Hospital from November 2020 to January 2023. With informed consent, after rinsing with aseptic normal saline twice, their implants were gently covered with a thin layer of tryptone soy agar medium. Thereafter, the implants were incubated at 37 ℃ with 5% CO 2. Changes on the surface and in the surroundings of the implants were observed every day for consecutive 2 weeks to avoid drying up by supplementing the medium when necessary. Once pathogen colonies formed, samples were collected at 3 independent sites using sterile swabs for laboratory identification. Comparisons were made between the samples from implant surface culture and the intraoperative multisite samples from conventional culture. Results:Included were a total of 75 patients [56 males and 19 females with an age of (46.2±15.4) years]. The most common infection site was the tibia (37 cases), and the most common type of implants was plate and screw (59 cases). The positive rate of implant surface culture was significantly higher than that of conventional culture (86.7% vs. 52.0%, P<0.001). 80.5% (29/36) of the negative patients detected by the conventional culture obtained positive results by the implant surface culture; three of the positive patients detected by the conventional culture obtained negative results by the implant surface culture. The culture results were positive by both culture methods in 36 patients, and consistent by both culture methods in 35 patients, yielding a consistent rate of 97.2% (35/36). The time for implant surface culture was significantly shorter than that for conventional culture [1 (1, 2) d versus 3 (3, 4) d] ( P<0.001). Of the 65 positive patients by the implant surface culture, 59 were detected with monomicrobial infection, with Staphylococcus aureus on the top (29 cases). Conclusion:As the implant surface culture, a novel method, may be superior to the conventional culture in a significantly higher positive rate and a shorter culture time, it may be used as an effective adjunct to the conventional culture in identification of pathogens for fracture device-related infection.

Mechanism of action of Coptis chinensis in the treatment of dental caries based on network pharmacology and experimental validation / 国际生物医学工程杂志

Objective:To explore the mechanism of action of Coptis chinensis in the treatment of dental caries using a network pharmacology approach and animal experiments. Methods:The active ingredients of C. chinensis and their targets were screened by the traditional Chinese medicine systems pharmacology (TCMSP) database and analysis platform, and the targets were searched online through the GeneCards database. The intersecting targets of C. chinensis and dental caries were screened at Venny 2.1, and the intersection targets were analyzed online for protein-protein interaction analysis and gene ontology (GO) and kyoto encyclopedia of genes and genomics (KEGG) enrichment. Then, Cytoscape was used to create a "component-target-pathway" network diagram. Rats were randomly divided into the model group and the C. chinensis group to establish a rat model of dental caries. Rats in the model group were repeatedly rubbed with a cotton ball soaked in 150 μl of 0.9% NaCl solution for 5 min, and rats in the C. chinensis group were repeatedly rubbed with a cotton ball soaked in C. chinensis (5.8 mg of C. chinensis in 150 μl of 0.9% NaCl solution) for 5 min. The two groups of rats were treated once a week for four consecutive weeks. The number of Streptococcus mutans colonies was counted, and serum serine/threonine protein kinase 1 (AKT1), JUN, interleukin-6 (IL-6), tumor necrosis factor (TNF), and B-cell lymphoma-2 (Bcl-2) were detected by enzyme immunoassay. Results:A total of 11 active ingredients in C. chinensis were found, which regulate multiple molecular pathways by intervening in 54 targets, thereby treating dental caries. Quercetin, berberine, flavodoxin, berberine infusion, and tetrahydroberberine were the core components, and AKT1, JUN, IL-6, TNF, and Bcl-2 were the core targets. GO analysis showed that BP mainly included cytokine activity, signaling receptor activator activity, signaling receptor modulator activity, cytokine receptor binding, and receptor ligand activity, etc.; and CC mainly included the response to lipopolysaccharides, the response to bacterial molecules, cellular responses to lipids, inflammatory responses, and negative regulation of cell population proliferation; MF mainly includes membrane rafts, membrane microregions, extracellular matrix, external encapsulated structures, and plasma membrane protein complexes, etc. KEGG analysis showed that advanced glycosylation end product-receptor for advanced glycosylation end products (AGE-RAGE), TNF, IL-17, Toll-like receptor, hypoxia-inducible factor-1 (HIF-1), mitogen-activated protein kinase (MAPK), nuclear factor-κB (NF-κB), epidermal growth factor receptor (EGFR), Janus kinase-signal transducer and activator of transcription (JAK-STAT), and phosphatidylinositol 3-kinase-protein kinase B (PI3K-Akt) signaling pathways have been associated with C. chinensis treatment. The results of animal experiments showed that serum Bcl-2 protein expression increased and serum AKT1, JUN, IL-6, TNF, and other proteins decreased after the C. chinensis treatment. Conclusions:C. chinensis can be involved in regulating the targets of dental caries through multiple pathways, with good therapeutic effects and a wide range of mechanisms of action, and is expected to be an important component in the development of proprietary Chinese medicines for the treatment of dental caries.
