Objective To systematically analyze the research status,highlights,and advancements of five-element music therapy(FEMT)in intervening depression with bibliometric methods.Methods Relevant research literature on FEMT for depression intervention was retrieved from China National Knowledge Infrastructure(CNKI),Wanfang Data,Chinese Science and Technology Journal Database(VIP),and Web of Science(WOS),spanning from January 1,2000 to August 6,2025.Bibliometric analysis was performed using Excel,VOSviewer,and CiteSpace,with a focus on dimensions like publication trends,journal distribution,institutional and author collaboration,keyword co-occurrence,clustering,and burst detection,and highly cited publications.Results A total of 382 articles were included,comprising 304 Chinese articles and 78 English articles.Annual publication volume in this field exhibited a steady upward trend,with Chinese literature initiating earlier and maintaining dominance,while English literature demonstrated marked growth from 2019 onward.Network analysis of institutional and author collaborations revealed collaborative networks centered on research teams led by Facai LIN(Nanjing University of Chinese Medicine)and Li LI(Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine),with Chinese authors and institutions remaining dominant contributors to English literature.Keyword analysis indicated that Chinese literature emphasizes clinical applications such as“depression”“five-elements music”“fivetone therapy”and“acupuncture”,whereas English literature prioritize“music therapy”“depression”“randomized controlled trial”and“anxiety”with a focus on mechanisms and standardization.Cluster analysis revealed a paradigm shift from traditional Chinese medicine(TCM)theoretical explanations to research integrating neurobiological mechanisms and modern technologies.Analysis of highly cited literature further corroborated this trend,indicating that FEMT research is transitioning from empirical clinical exploration to evidencebased mechanistic inquiry.Conclusion FEMT research on depression shows distinct thematic emphase,with Chinese literature focusing on TCM theory and clinical applications,while English literature emphasize evidence-based mechanisms.Future research should integrate systematic reviews and high-quality clinical trials and strengthen cross-institutional collaboration to enhance mechanistic evidence and broaden the scope of FEMT. 展开更多

OBJECTIVE: To explore the effects of traditional Chinese medicine(TCM) five-element music combined with acupoint application on perioperative sleep quality in patients undergoing joint replacement surgery. METHODS: In this study, a total of 122 patients with joint replacement surgery in Beijing Jishuitan Hospital were targeted from 2015 to 2018. All patients were grouped by random number table method. Among them, 61 patients with routine nursing were included in the control group. On this basis, the other 61 patients with acupoint application and TCM five-element music therapy were included as the observation group. 2 weeks later, the Pittsburgh Sleep Quality Index(PSQI) was used to evaluate sleep quality in all patients. The sleep improvement of the 2 groups was evaluated, and the patient was assessed for anxiety and depression, and the curative efficacy was evaluated. RESULTS: After 2 weeks of nursing, the PSQI of the patients improved significantly. The PSQI of the observation group was only 6.6 ± 2.4, and the control group decreased to 9.9 ± 2.7. The observation group was better than the control group, and the difference was statistically significant(P < 0.05). Comparing the 2 groups, the anxiety score of the observation group decreased to 4.8 ± 1.6, which was significantly lower than that of 6.9 ± 2.2 in the control group. The depression score of the observation group decreased to 4.6 ± 1.3, which was significantly lower than that of 6.8 ± 2.3 in the control group. In the control group, the negative emotion scores after nursing were better than those before nursing, and the difference was statistically significant(P < 0.05). Comparing the 2 groups, the effective rate of sleep improvement in the observation group was 96.6%, and the cure rate was as high as 49.1%. The control group was 82.0%, and the cure rate was 18.0%. The observation group was better than the control group, and the difference was statistically significant(P < 0.05). CONCLUSION: The combination of TCM five-element music with acupoint application can improve the perioperative sleep quality of patients undergoing joint replacement surgery, and it can help patients to relieve negative emotions. It is worth promoting. 展开更多

Objectives: To evaluate the effects of the Chinese medicine (CM) five-element music on quality of life for senior and non-senior advanced cancer patients. Methods: With a randomized controlled trial, 170 advanced cancer patients were randomly assigned to three groups: the CM five-element music group (68 patients), the Western music therapy group (68 cases), and the no music therapy group (34 cases). All patients of 70 years old or older were considered seniors and the remaining patients younger than 70 years were considered non- seniors. Patients in the CM five-element music group listened to CM five-element music, the patients in the Western music group listened to Western music, and the patients in the no music group did not listen to music. A course of treatment was 3 weeks, with 30 rain each day, 5 days a week. The Hospice Quality of Life Index- Revised (HQOLI-R) and Karnofsky performance score (KPS) were measured in the three groups before and after treatment. The symptom diary score was measured in the three groups every 3 days, 7 times in total. Results: CM five-element music group showed a significant difference of HQOLI-R, KPS and symptom diary score with other groups (all P〈0.01). There were significant differences of HQOLI-R, symptom diary score, and KPS after treatment in CM five-element music group and other groups in the non-senior subgroup (P〈0.05). Additionally, there were significant differences in HQOLI-R and KPS after treatment among the three groups in the senior subgroup (P〈0.05). Conclusions: CM five-element music therapy could improve the quality of life and KPS for senior and non senior advanced cancer patients, and it could improve subjective symptoms for non-senior advanced cancer patients. 展开更多

Objectives: To evaluate the effects of progressive muscle relaxation training (PMRT) combined with five elements music therapy of Chinese medicine (CM) for improving anxiety and depression of cancer patients. Methods: From June 2015 to March 2016, 60 cancer patients were included into the study. The patients were randomly assigned to a control group and a treatment group by envelope randomization, receiving PMRT and PMRT plus CM five elements music therapy, respectively, for 8 weeks. Hospital Anxiety and Depression Scale (HADS), Benefit Finding Scales (BFS), Functional Assessment of Chronic Illness Therapy-Spiritual (FACIT-Sp), and Intervention Expectations Questionnaire (IEQU) were adopted to assess the depression of the two groups before and after the treatment. Results: Four cases dropped out during the study, and 29 cases in the treatment group and 27 in the control group were included in the final analysis. Prior to the treatments, the baselines of the 4 questionnaires in the two groups showed no difference. After the 8-week treatment, the treatment group presented better levels of HADS, BFS and FACIT-Sp scores compared with the control group (P〈0.05). Among the single items of HADS, 4 items involving vexation, feeling fidgeted, pleasure and prospecting the future in the treatment group were improved compared with the control group (P〈0.05). Conclusions: As a simple and reliable and effective intervention, PMRT combined with five elements music therapy mitigated anxiety and depression of cancer patients. Cancer patients have been found to respond well to psychological intervention in areas regarding stabilisation of emotions, disease awareness, and therapeutic compliance. This brings about a great difference in improving their quality of life and psychological state, offers an effective approach to better self-management in cancer treatment. 展开更多

The international development of the petroleum industry has posed an urgent demand for the internationalization capabilities of both academic and professional master’s students.However,there is currently a shortage of such talent in the petroleum energy sector,along with a lack of a collaborative training system.Based on this,this study focuses on featured disciplines in the petroleum energy sector and systematically constructs an international talent training model centered around the“five-element synergy”of“government-school-enterprise-teacher-student.”Firstly,it defines the connotations of the five-element synergy:“government(strategic guidance)-school(platform support)-enterprise(demand verification)-teacher(leading transformation)-student(practical co-creation).”Secondly,it sets distinct training objectives for academic(focusing on academic innovation)and professional(emphasizing engineering practice)master’s students.Furthermore,it constructs a“categorized and layered,progressive and collaborative”curriculum system,builds an international faculty team through a“recruitment+training”dual-path approach,and cultivates students’sense of professional mission to“contribute to the nation’s energy sector”through a“macro+micro”perspective.This model provides a practical pathway for international talent training in the petroleum energy sector and holds significant importance for enhancing the overseas competitiveness of petroleum enterprises and safeguarding national energy security. 展开更多

Background:Music has proven to be vital in enhancing resilience and promotingwell-being.Previously,the impact of music in sports environments was solely investigated,while this paper applies it to study environments,standing out as pioneering research.The study consists of a systematic development of a conceptual framework based on theories of Uses and Gratification Expectancy(UGE)and perceived motivation based on music elements.Their components are observed variables influencing students’psychological well-being(as the dependent variable).Resilience is examined as a mediator,influencing the relationships of both observed and dependent variables.The main purpose of this study is to highlight the positive effects of online music consumption on the psychological well-being of students.Methods:Semi-structured qualitative interviews were conducted with eighteen final year creative multimedia undergraduate students belonging to five central region Malaysian universities,especially on their UGE needs,and a similar concept survey instrument with two hundred participants.The interview data were analysed through thematic analysis,while the survey data through descriptive and Partial Least Squares Structural Equation Modeling(PLS-SEM).Results:The results highlight that students gain motivation from online music,which positively affects their psychological well-being(β=0.190,p=0.003,f^(2)=0.037),while resilience significantly affects this relationship(β=0.562,p<0.001,f^(2)=0.461).However,the results also predict a partial relationship between constructs based on UGE with psychological well-being,mediated by resilience,i.e.,AT-UGE(β=0.021,p=0.783,f^(2)=0.000),SIPI-UGE(β=0.228,p=0.004,f^(2)=0.044).Conclusion:The outcome of the study reflected practical,meaningful,and statistically significant results.The majority of the predictors,with the exception of one,i.e.,AT-UGE,displayed a clear positive relation of online music consumption on the Psychological Well-being of students.Future research will explore varying contextual factors impacting online music-related gratifications,motivations,and resilience,along with additional potential mediators and moderators. 展开更多

This article studied on five elements system and set general and strict model expectations combining with Traditional Chinese Medicine Zang-fu organs theory,in which absolute stable state,conditional stable state or transient stability and instability in mathematical models were corresponding to human healthy state,sub-healthy state(pathological plateau phase) and health deterioration state respectively.Model parameters were set up according to the mutual generation and restriction relations among five elements.The dynamic model of Five-Elements System was built,of which impulse responses were corresponding to human response under TCM treatment.Analyses of initial value and excitation response were conducted by numerical simulation and results turned out to meet the requirements of general model expectation:five elements system dynamic model had self-organization function;there existed only one non-global stable point and instability region in the five-dimensional space consisting of variables,in which instability was corresponding to pathological deterioration;system stable region was an unbounded domain and it included the stable sub-regions of special straight line-type,ray-type and line segment-type.Among those ray-types,some contained "Regression Peak" were classed as conditional stable regions while others as absolute ones.The existence of this peak indicates that our body must exceed a "Regression Threshold" when transiting from sub-healthy state(pathological plateau phase) to healthy state through self-regulation mechanism.Impulse excitation can reduce certain threshold and then increase the system health level,which is complied with the operating principle of Five-Elements System and the empirical rule of TCM clinical practice.This model has revealed qualitatively the inherent movement law of Five-Elements System and thus provides a new analysis tool for basic theoretical study on TCM. 展开更多
