ObjectiveAutoimmune thyroiditis （AIT） is a complex and immune-mediated disorder， with no established treatment protocol. Both Western and traditional Chinese medicine （TCM） focus on the pathogenesis and treatment of AIT. This study evaluated the clinical consistency of existing AIT animal models based on the diagnostic criteria of both Western and TCM， using a novel evaluation method. Additionally， it proposed recommendations and future prospects for improving these models. MethodsA comprehensive literature review was conducted on existing AIT animal models， using databases and the diagnostic criteria of both Western and TCM. Core and accompanying symptoms of these models were scored based on the diagnostic criteria of both Western and TCM， and clinical consistency was assessed. ResultsMice are the primary experimental animals used in AIT modeling. Modeling methods include vaccine immunization， iodine induction， heterologous thyroid antigen immunization， and a combination of high iodine water and antigen immunization. The average consistency of clinical syndromes based on TCM and Western medicine is 40%， 60%， 54%， and 63%， with the highest consistency observed in the combined high iodine water and antigen immunization model. Pathological models based on TCM are less common， with the liver-stagnation-spleen-deficiency rat model showing high clinical consistency. While most models are designed according to Western medical theory， meeting the surface and structural effectiveness criteria of Western medicine. However， there is a lack of fine-tuning and clear differentiation of TCM syndromes. ConclusionCurrent AIT syndrome-disease combination animal models primarily reflect the pathological features of Western medicine， with limited integration of TCM syndromes. Future research should aim to combine the syndrome characteristics of TCM with the pathological features of Western medicine， creating multi-factor and dynamic syndrome-disease models. Such models would better facilitate an experimental platform that conforms to the theories of TCM， providing more comprehensive support and guidance for the pathogenesis and treatment strategies of AIT.

Objective: To systematically evaluate the willingness to receive influenza vaccines among Chinese medical staff, so as to provide the evidence for developing the influenza vaccination strategy and improving the coverage of influenza vaccination among medical staff. Methods: Publications pertaining to the willingness to receive influenza vaccines among Chinese medical staff were retrieved from international and national databases from January 1, 2010 to October 1, 2023, including CNKI, Wanfang Data, VIP, SinoMed, PubMed, Web of Science and Embase. A meta-analysis was performed using the software Stata 17.0, sensitivity analysis was performed using the leave-one-out method, and the publication bias was evaluated using Funnel plot. Results: Totally 674 publications were retrieved, and 17 case-control studies were finally enrolled, with 23 697 participants. Meta-analysis showed that the rate of willingness to receive influenza vaccines among medical staff in China was 52.8% (95%CI: 41.3%-64.4%). The rates of willingness to receive influenza vaccines were 40.2% (95%CI: 28.5%-51.8%) in 2019 and before and 67.2% (95%CI: 56.5%-77.9%) in 2020 and beyond; 54.6% (95%CI: 44.2%-65.0%) in men and 56.8% (95%CI: 49.3%-64.4%) in women; 53.6% (95%CI: 40.9%-66.2%) in doctors, 53.9% (95%CI: 41.0%-66.8%) in nurses, 62.8% (95%CI: 46.2%-79.3%) in technicians and 53.1% (95%CI: 36.1%-70.0%) in administrative and logistical staff; 77.4% (95%CI: 63.7%-91.2%) and 43.3% (95%CI: 30.5%-56.1%) in staff with and without a history of influenza vaccination; 49.8% (95%CI: 27.3%-72.3%) and 58.3% (95%CI: 43.9%-72.6%) in studies with a sample size of <1 000 and ≥1 000, and these differences were statistically significant (all P<0.05). Sensitivity analysis showed robustness of results, and Funnel plot showed publication bias. Conclusion The rates of willingness to receive influenza vaccines among medical staff in China ranged from 41.3% to 64.4%, and were lower in studies in 2019 and before, in men, in administrative and logistical staff and in staff without a history of influenza vaccination.

Tongue diagnosis is an indispensable objective basis for TCM diagnosis and treatment of epidemic diseases.To understand its application in an epidemic situation and to support in the diagnosis and treatment of infectious diseases using traditional Chinese medicine,the tongue image APP was implemented in this study to monitor the tongue image features of patients with new coronavirus pneumonia.It has been discovered through practice that the tongue image APP enables medical professionals to objectively,conveniently,quickly,and flexibly collect the patient's tongue image.It has also been discovered through the analysis of the tongue image characteristic data that the tongue image APP can,to a certain extent,objectively reflect the general law of the tongue image characteristics of the new crown pneumonia.According to the tongue image data gathered by the Tongue Image APP,Xinguan pneumonia patients'tongues were typically red,their fur was typically white,yellow,or both white and yellow,and they had a greater amount of thick and greasy fur.Nevertheless,there are still several issues with the Tongue APP application that have been noted:①The consistency of tongue shape and coating was poor;for instance,the inconsistency rate between a thin and fat tongue was as high as 62.96%;②The tongue image analysis index in the APP is still mostly a qualitative index,and the degree of discriminating is insufficient.The results of this study demonstrate that the tongue image information of different ages,sexes,disease classifications,and onset times does not reflect obvious differences and certain rules.③The tongue image characteristic indexes gathered by the tongue image APP are insufficient and do not include information on glossiness of tongue image(such as dark tongue)and tongue state.To promote the adoption of the tongue image APP and better support the prevention and treatment of epidemic diseases by traditional Chinese medicine,we should fully integrate modern advanced science and technology,improve the short videos of tongue coating,quantification of qualitative indicators,comprehensive collection of tongue image characteristic indicators,etc.

Objective:To observe any effect of exosomes derived from umbilical cord mesenchymal stem cells on pain, cartilage repair and the expression of transcriptional activator 3 (ATF-3) and growth related protein 43 (GAP-43) in the dorsal root ganglia (DRG), as well as to explore the mechanism of their relieving pain.Methods:Fifty-four male Sprague-Dawley rats were randomly divided into a sham-operation group, a monoiodoacetate group and an exosome group, each of 18. The knee cavities of the left hind limbs of all of the rats except those in the sham-operation group were injected with 50μl of monoiodoacetate to establish an arthritis pain model. The sham-operation group received only 50μl of saline solution as controls. Two weeks after the modelling, the knee joint cavities of the exosome group were injected with 50μl of exosomes, while the other two groups were injected with 50μl of normal saline. The rats′ mechanical and thermal pain thresholds were measured 1 day before the modeling, 7 and 14 days after the monoiodoacetate injection, as well as 7, 14 and 28 days after the exosome injection. Western blotting was used to detect the expression of ATF-3 and GAP-43 in the rats′ DRG, while hematoxylin and eosin staining was used to detect any cartilage repair.Results:Compared with the monoiodoacetate group, the latency of the mechanical and thermal pain thresholds had increased significantly in the exosome group 7 days after the exosome injection. The difference remained significant until the 28th day after the injection. The expression of ATF-3 protein decreased significantly and that of the GAP-43 protein increased significantly. Significant differences were observed in the average Osteoarthritis Research Society International (OARSI) knee cartilage score.Conclusions:Exosomes can alleviate the pain induced by monoiodoacetate adjuvant. The analgesic mechanism may be related to reducing nerve injury and promoting nerve and cartilage repair, with the nerve repair earlier than cartilage repair.
