- Abstract: BACKGROUND:Electrospun porous nanofiber exhibits excellent properties and designability.It is an effective way to control the release of traditional Chinese medicine and improve the bioavailability to design an advanced drug delivery system,which has a broad application prospect. OBJECTIVE:To review the construction methods of the electrospinning drug delivery system of traditional Chinese medicine and its related research progress in the medical field. METHODS:The literature search was performed in CNKI,PubMed,and Web of Science databases with the search terms"electrospinning,traditional Chinese medicine,drug carrier,drug delivery system,tissue engineering,dressing"in both English and Chinese for articles published from 2013 to 2023.Finally,62 articles were included in this review. RESULTS AND CONCLUSION:(1)The key elements of the electrospinning drug delivery system of Chinese medicine preparation are substrate material,traditional Chinese medicine composition,and drug loading method.(2)The preparation of the electrospinning drug delivery system of Chinese medicine can be carried out according to the application scenario and therapeutic purpose.Firstly,the types of Chinese medicine are selected,then the polymer matrix and solution suitable for them are selected,and finally,the fiber structure is designed according to the drug release requirements and the appropriate drug loading method is adopted.(3)At present,the medicinal agents used are mainly plant Chinese medicine,and there is a lack of systematic research on animal and mineral Chinese medicine.(4)Blended drug loading is the most studied and applied drug loading method,and its drug release characteristics and adaptation scenarios are constantly expanded by optimizing the physicochemical properties of the solution and selecting the diversity of loaded substances.Multilayer fibers with different compositions and properties can be prepared by coaxial,multi-axis,and sequential electrospinning methods,which have broad development prospects.(5)The early application of the electrospinning drug delivery system of Chinese medicine focused on medical dressings according to the antibacterial and hemostatic functions.In recent years,it has been studied in the field of tissue engineering because some components of traditional Chinese medicine can promote cell adhesion,proliferation,and differentiation.(6)At present,the research mainly focuses on the characterization and optimization of loading materials,processes,physicochemical properties,and biological properties,but the research on the mechanism is less.Its clinical application has not been widespread;the adverse reactions in vivo and the interaction between its degradation behavior and drug release behavior are still unknown.(7)Future studies need to consider:We should expand the application of Chinese medicine by improving the physicochemical properties and increasing the purification of Chinese medicine extracts.We need to comprehensively study the therapeutic effects and application mechanisms of Chinese medicine,and clarify the interaction of degradation behavior and drug release behavior,to achieve a more perfect combination and application of Chinese medicine and electrospinning nanofibers under a more accurate mechanism.
