RESUMEN
Wilson's disease （WD） is a copper metabolism disorder caused by mutations in the ATP7B gene， with diverse phenotypes and complex pathogenesis. It is one of the few rare diseases that can achieve good clinical efficacy through standardized treatment. Since there are few systematic reviews of this disease， we summarize the pathogenesis and treatment methods of WD from traditional Chinese and western medicine by reviewing the literature related to WD. In western medicine， ATP7B gene mutation is considered as the root cause of WD， which affects copper transport and causes copper metabolism disorders. The excessive copper deposited in the body will result in oxidative stress， defects in mitochondrial function， and cell death. Western medicine treatment of WD relies mainly on drugs， and copper antagonists are the first choice in clinical practice， which are often combined with hepatoprotective and antioxidant therapy. Surgery is a common therapy for the patients with end-stage WD， and gene therapy provides an option for WD patients. According to the traditional Chinese medicine （TCM） theory， WD is rooted in constitutional deficiency and copper accumulation and triggered by dampness-heat accumulation or phlegm combined with stasis. The patient syndrome varies in different stages of the disease， and thus the treatment should be based on syndrome differentiation. The TCM treatment method of nourishing the liver and kidneys and warming the spleen and kidneys can address the root cause. The methods of clearing heat and drying dampness， resolving phlegm and dispelling stasis， and soothing liver and regulating qi movement can be adopted to treat symptoms. On the basis of syndrome differentiation， special prescriptions for the treatment of WD have been formulated， such as Gandou decoction， Gandouling， and Gandou Fumu decoction， which have been widely used in clinical practice. TCM and western medicine have their own advantages and shortcomings. The integrated Chinese and western medicine complementing with each other demonstrates great therapeutic potential. This paper summarizes the pathogenesis and treatment of WD with integrated Chinese and western medicine， aiming to provide a reference for the clinical diagnosis and treatment of this disease.

RESUMEN
The apprenticeship education of Traditional Chinese medicine(TCM)is an important pathway for the cultivation of talents in TCM education.The combination of institutional education and apprenticeship education is considered to be the most suitable educational model that aligns with the inherent characteristics of TCM education.The current status of TCM education in western medical institutions and the main challenges include the difficulty in transitioning between western and Chinese medical reasoning and limited clinical internship hours for TCM.The strengths and features of TCM apprenticeship education lie in cultural heritage,classical teachings,mentorship,practice orientation and personalized education.Therefore,integration of TCM apprenticeship education and clinical internships for western medical students represents a new educational model for medical undergraduates.

RESUMEN
BACKGROUND:The temporal and spatial expression of fibroblast growth factor receptors 1 and 2 remains a controversial issue during kidney development,so the relationship between them and kidney development remains unclear. OBJECTIVE:To observe the dynamic expression of fibroblast growth factor receptors 1 and 2 during kidney development of mice,and to investigate the relationship between them and kidney development. METHODS:The kidneys of fetal mice[embryotic days(E)12,14,16,and 18]and neonatal mice[neonatal days(N)1,3,7,14,24,and 40]were selected to examine the temporal and spatial expression of fibroblast growth factor receptors 1 and 2 by immunohistochemistry method in kidney tissues,and quantitative analysis was performed using western blot assay. RESULTS AND CONCLUSION:(1)Immunohistochemistry showed that fibroblast growth factor receptor 1 was mainly localized in metanephric tissue surrounding the tip of the ureteral bud at E12.Subsequently,fibroblast growth factor receptor 1 was expressed in immature renal corpuscles at various stages,some distal convoluted tubules and capillary loops.The positive site was mainly concentrated in the generative region.Fibroblast growth factor receptor 2 was initially expressed in both ureteral buds and metanephric tissue.Fibroblast growth factor receptor 2 was localized in immature renal corpuscles,distal tubules,collecting ducts and thin segments of medullary loops with kidney development.However,the expression of renal corpuscles was weak.(2)Stereology and western blot assay showed that the expression of fibroblast growth factor receptor 1 was high before birth and gradually decreased after birth,while the expression was very low after N7 day.The expression level of fibroblast growth factor receptor 2 increased gradually with the kidney development and tended to be stable after N7 day.(3)The results exhibit that fibroblast growth factor receptors 1 and 2 are expressed spatially and temporally during kidney development.It is speculated that fibroblast growth factor receptors 1 and 2 may influence nephron development and maturation,and fibroblast growth factor receptor 2 is critical during the formation of ureteral buds and morphology.

Objective This paper summarizes and evaluates the existing animal models of Post-infectious irritable bowel syndrome(PI-IBS)based on the clinical diagnostic criteria and symptom characteristics of PI-IBS in Chinese and western medicine.The goal of this study is to seek out animal models with a high degree of clinical agreement between Chinese and western medicine,and to provide an accurate animal model for the prevention and treatment of PI-IBS in traditional Chinese medicine.Methods The animal strains,modelling methods,and mechanisms of the existing PI-IBS animal models were summarized based on the clinical diagnostic features and symptomatology of PI-IBS,as well as the degree of match was evaluated and the strengths and weaknesses of the preparation of animal models were analyzed,by reviewing the articles related to PI-IBS animal experiments and the preparation of animal models.Results A thorough analysis discovered that Campylobacter jejuni infection model,Trichinella infection model,and liver depression and spleen deficiency syndrome in models of disease and symptom combination showed a comparatively high level of clinical agreement between Chinese and western medicine.Conclusion The existing PI-IBS models had the high degree of coincidence with western medicine,Chinese medicine four diagnoses and syndrome are generally less embodied and collected in the modeling process.The primary symptoms in Chinese medicine diagnosis are primarily based on the observation of animal apparent behaviors,while the observation of the sub-syndrome manifestations is relatively less,which results in failure of judgment of TCM syndrome types.Therefore,it is still necessary to further standardize the criteria for evaluating symptoms and the techniques for identifying disease-syndrome combination animal models.PI-IBS model with the syndrome-clinical characteristics in Chinese and western medicine has significant application value and prospects in the future.The multifactorial composite method of western medicine pathological injury+Chinese medicine etiological stimulation can establish a PI-IBS model with a higher degree of coincidence,which can provide theoretical support for the study of the pathogenesis of PI-IBS,the difference of syndrome,and the prevention and treatment with integrative Chinese and western medicine.It is crucial to guide the clinical diagnosis and treatment of PI-IBS.
RESUMEN
Chronic hepatitis B （CHB） is still a major public health issue in China， and without effective control， it can further progress to liver cirrhosis and liver cancer， bringing huge social and economic burdens. At present， antiviral therapy is the main treatment method for CHB， and integrated traditional Chinese and Western medicine therapy is the characteristic treatment method for CHB in China and can improve clinical efficacy by complementing each other’s advantages. In order to promote the concept integrated traditional Chinese and Western medicine collaborative diagnosis and treatment， facilitate the development of integrated traditional Chinese and Western medicine diagnosis and treatment techniques for CHB， and establish standardized disease diagnosis and treatment regimens， Expert Committee on Hepatology in Doctor Society of Integrative Medicine， Chinese Medical Doctor Association， established a consensus expert group to discuss and formulate Expert consensus on integrated traditional Chinese and Western medicine diagnosis and treatment of chronic hepatitis B， which elaborated on the concept of integrated traditional Chinese and Western medicine collaborative diagnosis and treatment from the four aspects of CHB epidemiology， pathogenesis and etiology， integrated traditional Chinese and Western medicine diagnosis and syndrome differentiation， and integrated traditional Chinese and Western medicine therapy and proposed related recommendations， in order to improve the prognosis and quality of life of CHB patients.
