Esophageal cancer is a digestive tract malignancy with high morbidity and mortality and mainly occurs in males. The 5-year survival rate is lower than 20%. In China， the morbidity and mortality of esophageal cancer rank the first in the world， seriously threatening national health. The pathogenesis of esophageal cancer is diverse， which is generally considered as the consequence of environmental-genetic-gene interaction. In addition to genetic factors and regional characteristics， gene mutation， RNA interference， DNA damage repair， tumor microenvironment， dietary habit， chronic adverse stimulation， and inflammatory reaction are all involved in the occurrence and development of esophageal cancer. However， there is no unified and accurate conclusion. Clarifying the exact pathogenesis of esophageal cancer is of great significance for its early screening， diagnosis， prevention， treatment， and prognosis. Surgery， radiotherapy， and chemotherapy are the three effective methods for the treatment of esophageal cancer. However， due to the atypical early symptoms， most patients have missed the best operation period when diagnosed， resulting in poor clinical prognosis. Moreover， radiotherapy and chemotherapy will cause side effects such as loss of appetite， low immune function， esophagitis， pneumonia， and malnutrition， which is not conducive to the prognosis and treatment maintenance of patients. With definite efficacies on esophageal cancer， traditional Chinese medicine （TCM）， which is flexible and diverse in the treatment， can primarily or alternatively be involved in the treatment of esophageal cancer. TCM can eliminate postoperative complications and postoperative infections and relieve adverse gastrointestinal reactions， weakened immune function， and organ damage caused by radiotherapy and chemotherapy. It can enhance clinical efficacy and improve the quality of life of patients. Therefore， it is necessary to systematically summarize the clear pathogenesis or risk factors of esophageal cancer and review the clinical characteristics of TCM in the prevention and treatment of esophageal cancer to facilitate the early screening， diagnosis， and treatment of esophageal cancer and promote the application of TCM in the prevention and treatment of esophageal cancer and related adverse reactions.

In recent years， with the changes of people's life rhythm and living environment， the incidence of gastric ulcer has shown an increasing trend year by year， and the affected population has become younger and younger. In order to further explore the pathogenesis of gastric ulcer and its diagnosis and treatment methods， a variety of animal models of gastric ulcer have been established clinically， such as stress type， chemical factor type， pyloric ligation type， helicobacter infection type and disease-syndrome combination type. The authors intend to summarize the modeling methods and advantages and disadvantages of existing models on the basis of reviewing the etiology， pathogenesis and diagnostic criteria of gastric ulcers. It was found that the non-injurious stress method （restraint stress， restraint immersion stress and restraint freezing stress， etc.）+traditional Chinese medicine （TCM） syndrome modeling， acetic acid gavage method+TCM syndrome modeling were ideal choices for replicating animal models of acute and chronic gastric ulcer. At the same time， the analysis of the coincidence degree between each gastric ulcer model and the clinical disease characteristics of Chinese and western medicine showed that the coincidence degree of western medicine diagnostic criteria was higher than that of TCM diagnostic criteria. The successful judgment of the model was also based on western medicine diagnosis. In short， the model is insufficient in depth and breadth. It only detects a few core indicators and main indicators， ignoring the impact of secondary indicators on the diagnosis of the disease. There is also a big gap between the disease-syndrome combination model and the TCM clinical syndromes of this disease. Therefore， the depth and width of the model evaluation criteria should be strengthened， and the evaluation system of the disease-symptom combination model should be improved， in order to provide a more accurate reference for the replication of gastric ulcer models， and to replicate animal models of gastric ulcer with high coincidence degree of Chinese and western medicine for research purposes.

ObjectiveTo explore the possible mechanism of total flavonoids of peony flower （TFPF） in protecting rats from gouty nephropathy and provide data support for the pharmaceutical research on the treatment of gouty nephropathy. MethodGouty nephropathy rat model was established by adenine combined with ethambutol. Rats were randomly assigned into blank control group， model group， allopurinol （42 mg·kg^-1） group， Tongfengshu tablets （600 mg·kg^-1， positive control） group， and TFPF （260， 130， and 65 mg·kg^-1） groups. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of tumor necrosis factor-α （TNF-α）， monocyte chemoattractant protein-1 （MCP-1）， interleukin-1β （IL-1β）， and interleukin-18 （IL-18） in rat serum and those of transforming growth factor-β₁ （TGF-β₁） and IL-1β in renal homogenate. Hematoxylin-eosin（HE） staining was carried out for observation of the morphological changes of renal cells. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling （TUNEL） was conducted for observation of the DNA damage in renal cells. The expression of NOD-like receptor protein 3 （NLRP3）， cysteine aspartic acid protease（Caspase）-1 and IL-1β were observed by immunohistochemistry. The expression levels of NLRP3， Caspase-1 and nuclear transcription factor -κB （NF-κB） in renal tissues were detected by Western blot. ResultCompared with blank group， the contents of TNF-α， MCP-1， IL-1β， IL-18， and TGF-β₁ in serum of model group were significantly increased （P<0.01）， and the expressions of NLRP3， Caspase-1， NF-κB and IL-1β in kidney of model group were significantly increased （P<0.01）. The renal tissue cells showed cytoplasmic swelling， cell membrane rupture， and the number of nuclear pyknotic fracture increased. The positive rate of TUNEL staining was significantly increased in model group （P<0.01）， and the contents of IL-1β and TGF-β₁ in renal tissue homogenate were significantly increased （P<0.01）. Compared with model group， the contents of inflammatory factors TNF-α， IL-1β and IL-18 in serum of rats in TFPF high- and medium-dose groups could be decreased to different degrees （P<0.05， P<0.01）， while the content of MCP-1 in TFPF high-dose group was significantly decreased （P<0.01）. The content of TGF-β₁ in renal tissue homogenate in TFPF high- and medium-dose groups was significantly decreased （P<0.05， P<0.01）， and the content of IL-1β in renal tissue homogenate in TFPF medium-dose group was significantly decreased （P<0.01）. HE staining showed that each dose group of TFPF could improve the status of renal tubular epithelial cells， reduce cytoplasmic swelling and the number of nuclear pyknosis to varying degrees. The positive rate of TUNEL staining was decreased （P<0.01） and DNA damage was decreased. The expression of NLRP3， Caspase-1， IL-1β and NF-κB protein in renal tissue cells was inhibited （P<0.05， P<0.01）. ConclusionTFPF protects rats from gouty nephropathy by inhibiting the secretion of inflammatory cytokines. Specifically， it may inhibit the activation of NF-κB and NLRP3/Caspase-1 pathways to reduce the expression， maturation， and release of inflammatory cytokines such as IL-1β and IL-18 and further inhibit pyroptosis， thereby reversing the inflammatory injury of kidney in gouty nephropathy.

MethodThe topical functions， usage， dosage， dosage form， application method， and prescription of the preparations for external use in the Pharmacopoeia were analyzed. ResultThe Chinese pharmacopoeia 2020 edition includes a total of 138 prescription preparations for external use， the specific clinical usage， dosage， administration method， and efficacy evaluation of which remain unclear. These preparations can be used to treat a wide range of diseases. Specifically， the use in orthopedics and traumatology （36 preparations， accounting for 26.09%） is dominant， followed by that in internal medicine， surgery， and throat. The major application method is directly applying to the diseased area （35 preparations， 25.36%）. The main dosage forms are ointment （40 preparations， 28.99%） and powder （24 preparations， 17.39%） and others include liniments， suppositories， tinctures， and sprays. The clinical usage and dosage of these preparations are mostly unclear. Only 48 preparations （34.78%） are recorded with clear dosage and frequency of use， and 45 preparations （32.61%） have neither clear dosage nor frequency of use. The 138 prescription preparations for external use include 211 single medicines， of which 44 single medicines can be used alone. The single medicines are mostly used for heat clearing （48 preparations， 22.75%）. ConclusionThe Chinese pharmacopoeia 2020 edition （Volume I） records a large number of prescription preparations for external use， and the number shows an increasing trend. However， the usage， dosage， and efficacy evaluation criteria of these preparations remain to be improved and need in-depth research.

This article aims to provide a good experimental method for the study of drug treatment of ulcerative colitis. According to the characteristics of ulcerative colitis's clinical symptoms, common ulcerative colitis animal models were analyzed. Based on the characteristics of clinical symptoms of traditional Chinese medicine and Western medicine for ulcerative colitis disease, the existing commonly used animal models of ulcerative colitis were analyzed to summarize the current matching degree, advantages and disadvantages of the exi-sting animal models of ulcerative colitis and clinical symptoms. At present, studies on ulcerative colitis mainly adopt four types of induction modeling methods, such as immunization, chemical stimulation, compound method and gene model. There are many reported methods of colitis modeling, but no model can reflect the characteristics of clinical symptoms of ulcerative colitis treated with Western or Chinese medicine. This article summarizes the characteristics, clinically relevant symptoms and applicable scope of immunization, chemical stimulation, compound method, and gene model, so as to provide a reliable animal model for subsequent studies of prevention and treatment of colitis.

Based on the characteristics of clinical symptoms of secretory otitis media in traditional Chinese and Western medicine,by reference to clinical diagnostic criteria,efforts were made to analyze and establish the Western medical diagnostic criteria and traditional Chinese medicine( TCM) syndrome differentiation criteria for secretory otitis media,and summarize the modeling methods and model characteristics of secretory otitis media animal models. According to the clinical diagnostic criteria and symptom characteristics,the coincidence degree between the existing animal models and clinical symptoms was evaluated,and its advantages and disadvantages were defined. On the basis of the statistical results,there were fewer methods for modeling secretory otitis media animal models,and only a specific relevant pathogenic mechanism could be revealed. Among them,the model with a higher coincidence degree was genetic engineering technology modeling and injection into the middle ear vesicles. The two modeling methods of bacterial factors highly coincided with the clinical symptoms of Western medicine,but both failed to reflect the TCM syndrome type. Therefore,establishing an animal model that simultaneously reflects the characteristics of clinical symptoms of secretory otitis media in traditional Chinese and Western medicine,and improving the evaluation criteria of secretory otitis media based on animal models are the main tasks of future studies on secretory otitis media.

Based on the clinical characteristics of chronic atrophic gastritis in traditional Chinese and Western medicine, the domestic and foreign relevant literature reports and animal models of chronic atrophic as well as the clinical diagnostic indicators of traditional Chinese and western medicine, chronic atrophic gastritis evaluation standard was summarized to evaluate and analyze the coincidence degree of clinical symptoms of the existing chronic atrophic gastritis animal models. The statistical results found that modeling methods with a higher coincidence degree with the existing chronic atrophic gastritis animal models are disease and syndrome combination mode-ling, surgical modeling, multifactor comprehensive modeling and MNNG modeling. Although the animal models were reproduced by such methods as etiology, pathogenesis and disease and syndrome combination similar to those of human beings, there is still a big gap with the natural disease state. Further in-depth studies and improvement shall be made in clinical practice in the hope to provide refe-rence for clinical practice and experimental studies of chronic atrophic gastritis.
