ABSTRACT
ObjectiveTo statistically analyze the efficacy and application characteristics of animal-derived drugs in the 2020 edition of the Pharmacopoeia of the People's Republic of China （referred to as Chinese Pharmacopoeia）， and provide data references for the research and application of animal-derived drugs. MethodAnimal-derived drugs included in the 2020 edition of the Chinese Pharmacopoeia were selected and screened. Information such as the classification， nature and flavor， meridian tropism， usage， dosage， toxicity or contraindications of single animal-derived drugs were statistically analyzed. The efficacy and clinical application analysis of externally applicable Chinese medicinal preparations containing animal-derived drugs， the dosage forms of preparations containing animal-derived drugs， and the contraindications of their use were also analyzed. The above information was recorded in an Excel spreadsheet for statistical analysis. ResultThe 2020 edition of the Chinese Pharmacopoeia clearly records a total of 51 types of animal-derived drugs. Among them， liver-calming and wind-relieving drugs and deficiency-tonifying drugs are the most common in the efficacy classification of animal-derived drugs. The properties are mainly categorized as neutral and salty， with meridians including liver， kidney， heart， and lung meridians with a frequency of >10 times. Most animal-derived drugs are used in decoctions and pills， with the decoction method being the primary method for decoction. The common dosage of animal-derived drugs is 3-9 g， 5-10 g， or 3-6 g， and animal-derived drugs are used externally in appropriate amounts. In addition to mentioning the toxicity of drugs， the most common precautions for animal-derived drugs are caution and prohibition for pregnant women. Externally applicable Chinese medicinal preparations containing animal-derived in the Chinese Pharmacopoeia are widely used in various departments such as pediatrics， gynecology， orthopedics and traumatology， stomatology， internal medicine， surgery， dermatology， ophthalmology， and otorhinolaryngology， with extensive clinical applications. The dosage forms of preparations containing animal-derived drugs are mainly pills， capsules， tablets， and capsules. Animal-derived drugs are mainly in the form of fine powder before use. The precautions for use in preparations mainly focus on the contraindications for pregnant women and children. ConclusionThe clinical application of animal-derived drugs included in the 2020 edition of Chinese Pharmacopoeia is extensive and has unique efficacy. However， there are still problems such as imperfect quality standards and unclear mechanisms of action for animal-derived drugs， which require further research to better utilize the advantages of internal and external use of animal-derived drugs. In addition， non-medicinal parts of animals also have development and utilization value， which should be fully explored and utilized to achieve the green development of animal-derive drug resources.
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.
