Abstract:
ObjectiveEsophageal cancer is a common malignant tumor of the upper gastrointestinal tract， and has high incidence and mortality in China. Its incidence is increasing year by year， and survival rate is low， thus seriously threatening human life and health. To further explore the pathogenesis of esophageal cancer and its systematic and efficient diagnosis and treatment methods， the animal models of esophageal cancer was evaluated according to the animal model evaluation method previously established by our team based on the characteristics of its clinical symptoms of traditional Chinese and western medicine， and suggestions for model improvement were proposed. MethodThe existing animal models of esophageal cancer were summarized through China National Knowledge Infrastructure （CNKI） and Wanfang Data. The relevant indexes of the models were assigned， and their coincidence with the clinical diagnostic guidelines of traditional Chinese and western medicine for esophageal cancer was evaluated. ResultExcept the spontaneous animal model of esophageal cancer with high clinical coincidence adopted in few studies， the animal model induced by methylbenzylnitrosamine was in good agreement with the clinical data， which simulated the etiology and pathogenesis of esophageal cancer to a certain extent. The model partially reflected some indicators of clinical diagnosis in western medicine， and also indicated the body weight loss， purple nail and increased number of drinking in traditional Chinese medicine （TCM）. However， there was still a lack of differentiation of TCM syndromes. ConclusionOn the basis of the original model， the animal model induced by methylbenzylnitrosamine and the mouse model of xenogeneic gastric wall transplantation of human esophageal cancer cells were applied， which were intervened with the factors of phlegm and qi mutual obstruction syndrome， blood stasis and phlegm stagnation syndrome， Yin deficiency and internal heat syndrome and Qi deficiency and yang weakness syndrome， and were distinguished to reflect the performance of TCM syndrome. The animal model of esophageal cancer combined with TCM syndrome was thus obtained， which embodied the clinical symptoms of esophageal cancer in TCM， and the characteristics of the animal model combined with TCM syndrome， and simulated the clinical practice of traditional Chinese and western medicine， providing an accurate pathological model carrier for basic research.
