As an innovative form of combining traditional aromatherapy with modern nasal medicine delivery technology， "olfactory administration of Chinese medicine" carries the theoretical essence of traditional Chinese medicine （TCM）， which is "moving and channeling Qi and fragrance， dredging and awakening the mind". Based on the systematic records of olfactory therapies in ancient books in emergency care， disorders of consciousness， lung system， and gynecological diseases， this paper examines the historical evolution of its clinical application， and elucidates the profound historical basis and theoretical feasibility of "olfactory administration of Chinese medicine" as a new form. Combined with the innovation and precise application of modern Chinese medicine olfactory agents in multi-system diseases such as nervous， respiratory， and cardiovascular diseases， this paper further analyzes the multi-dimensional mechanism of olfactory receptor pathway， olfactory brain pathway， nasal mucosal blood vessels， and lymphatic channels， and demonstrates its advantages of rapid onset， targeted brain entry， and systemic regulation. Under the background of continuous growth in the demand for external TCM treatment， continuous breakthroughs in the technology of nasal dosage forms， and increasingly accurate drug delivery paths， Chinese medicine olfactory agents have shown significant practical applicability and development potential. This study aims to provide theoretical support and practical direction for the system construction of this form.

Objective To establish the method of combined hepatocyte growth factor (HGF) with epidermal growth factor (EGF) cultured human gallbladder epithelial cells(HGBECs) in vitro .Methods The epithelial layer was peeled away from human gallbladder ,epithelial layer were digested with collagenase Ⅳ and scraped repeatedly .HGBECs were isolated and seeded in cell cul-ture plates containing medium supplemented with or without 10 ng/mL EGF or with 10 ng/mL HGF and 10 ng/mL EGF respec-tively .Then the morphologic changes of the cells were observed and taken photos with inverted phase contrast microscope ,and counted number of cells ,MTT assay detected vigor of cells in different groups .Results The number of the HGBECs of the HGF+EGF group was obviously more than the EGF group ,the duration of the HGBECs of the HGF+ EGF group was obviously longer than the EGF group(19 .3 ± 2 .5)d vs .(14 .2 ± 2 .4)d ,P< 0 .05 .And the HGBECs of the group with HGF+ EGF had better cell vigor .Conclusion HGF combines with EGF added to medium can obviously promote the proliferation of HGBECs and prolong the duration and stabilize morphology of HGBECs in vitro .
