Objective:To explore the psychological acceptance mechanism of appropriate Traditional Chinese Medicine (TCM) techniques among patients with abnormal uterine bleeding (AUB) .Methods:Using purposive sampling, AUB patients experiencing menstruation but not yet menopausal were recruited from Zhumadian City, Henan Province, and Jiaxing City, Zhejiang Province, between November 2022 and January 2023. Semi-structured interviews were conducted, and the collected data were analyzed using content analysis.Results:A total of four main themes were identified: individualized disease perception and treatment experience; awareness and treatment experience of appropriate TCM techniques; cultural identity and influence of traditional beliefs; and the need for science communication and safety regarding TCM techniques.Conclusions:While AUB patients show a generally high level of acceptance toward appropriate TCM techniques, their understanding of both AUB and the relevant TCM therapies remains limited. Multiple factors influence patients' choices, and some concerns and doubts still persist during the decision-making process.

Objective To develop miniature pig model of coronary microembolization (CME) by easy and cost-effi-cient technique. Methods A total of 11 miniature pigs were divided into control group (n=5) and CME group (n=6). Femo-ral artery was punctured using 21 gauge needle that is normally used for transradial procedures. Microspheres were injected into the left anterior descending artery of the CME group by 5 F coronary radiography catheter and 1.8 F coronary micro-guide catheter. Serum concentrations of brain natriuretic peptide (BNP) and cardiac troponin I (cTnI) were evaluated just be-fore CME and 6 hours after CME. Apical myocardial pathological lesions were evaluated by optical microscope 6 hours after CME. Results All miniature pigs in control group survived, but one died in the CME group. 5 F coronary radiography cathe-ter and 1.8 F coronary micro-guide catheter reached designated location successfully. Before CME, serum BNP (ng/L:143.00 ± 13.51 vs 134.00 ± 15.57) and cTnI (μg/L:0.39 ± 0.09 vs 0.38 ± 0.10) showed no significant differences between these two groups (t values are 0.976 and 0.294 respectively,both P>0.05). By contrast, serum BNP (561.00 ± 80.65) and cTnI (2.75±0.58) were much higher in CME group than those (BNP 139.00±13.87;cTnI 0.54±0.14 ) in control group after CME (t values are 11.530 and 8.337 respectively,both P＜0.001). In CME group, microspheres, micro-infarction and inflammatory cell infiltration were seen under an optical microscope which are absent in control group. Conclusion Using new surgical consumables can successfully develop miniature pig model with CME. And the technique is simple, cost-efficient, practical so it is worth promoting.
