Hemorrhoids are common anorectal diseases with complex pathogenesis, and there is still a lack of ideal experimental animal models for research on their prevention and treatment. In this paper, Chinese and English databases are searched with the keywords "hemorrhoids" and "animal model", and 36 relevant studies are finally included. The shortcomings of existing hemorrhoid animal models in integrating the clinical disease and syndrome characteristics of traditional Chinese and Western medicine are systematically analyzed, and the consistency of various models with clinical practice is evaluated. The studies are divided into four categories according to modeling methods: chemical modeling, physical modeling, biological modeling, and combined modeling. The clinical consistency of modeling is evaluated in combination with the diagnostic points of hemorrhoids in traditional Chinese and Western medicine. The results show that there are significant differences in the reproduction of clinical indicators by different modeling methods. According to clinical consistency, the models can be divided into three grades: high-consistency models are mainly based on combined modeling methods (such as induction by carrageenan combined with norepinephrine hydrochloride), which can more comprehensively simulate core pathological changes such as venous congestion and local inflammation; moderate-consistency models adopt single chemical or physical intervention (such as local inflammation induced by croton oil or vein ligation), which can only reproduce part of the pathological process; low-consistency models mostly adopt direct stimulation, with limited research value for pathological characteristics. Existing animal models have obvious advantages in replicating Western medical structural lesions of hemorrhoids, but they still have obvious defects in simulating the chronic disease course and stably reproducing the characteristics of traditional Chinese medicine syndromes, and a unified standard has not yet been formed for the traditional Chinese medicine evaluation system of models. In conclusion, it is still necessary to further explore the construction of high-quality integrated disease and syndrome animal models for hemorrhoids in traditional Chinese and Western medicine. Future research should integrate the theories of traditional Chinese and Western medicine, adopt multi-factor chronic modeling strategies, and establish a standardized comprehensive evaluation system covering macroscopic signs and microscopic indicators. This paper provides a reference for constructing standardized integrated disease and syndrome animal models of hemorrhoids that conform to the pathological changes of Western medicine and take into account the characteristics of traditional Chinese medicine syndromes, with the aim of providing more effective experimental tools for research on the pathogenesis of hemorrhoids and their integrated prevention and treatment with traditional Chinese and Western medicine.

Objective: To explore the effect and mechanism of lycorine on oxaliplatin ( OXA) induced chemotherapy pain in mice． Methods : 40 mice were randomly divided into 4 groups，10 mice per group，which were respectively divided into control group，model group，administration group，and inhibitor group．A mouse model of chemotherapy induced pain was established by intraperitoneal injection of OXA for 5 consecutive days．Intrathecal administration of lycorine was performed．Behavioral changes and expression levels of inflammatory related proteins were detected . Results : Compared with control group，model group mice exhibited the increased number of spontaneous flinches，decreased mechanical nociceptive threshold，decreased movement distance and latency，and up-regulated expression levels of interleukin-1 β (IL-1 β) ，astrocytic marker glial fibrillary acidic protein ( GFAP) ，cyclooxygenase-2( COX-2) ，NOD-like receptor protein 3 ( NLRP3 ) ，cysteinyl aspartate and specific proteinase 1 ( Caspase- 1) ．Compared with model group，lycorine administration reduced the number of spontaneous flinches，increased mechanical nociceptive threshold ，enhanced the movement distance and latency ，bound and reduced COX-2 expression，down-regulated the expression levels of IL-1 β , GFAP ，NLRP3 and Caspase-1． Conclusion Lycorine reduces COX-2 expression，inhibits NLRP3 inflammasome activation，suppresses spinal inflammation，consequently alleviates pain behaviors and improved motor ability of mice.
