Objective To clarify the influencing factors of defensive medicine and provide ideas for preventing and re-solving defensive medicine.Methods Literature related to defensive medicine was searched,personnel related to de-fensive medicine were interviewed,and literature and interview data were coded with the method of grounded theo-ry,and related concepts and categories were summarized.Results After three levels of coding,52 initial concepts,23 initial categories,7 sub-categories and 3 main categories were sorted out,and the correlation among influencing factors was analyzed to build a three-dimensional model of"doctor-patient relationship-institutional system-social environment"influencing factors and their mechanism of action.Conclusion The influencing factors of defensive medi-cine mainly include doctor-patient relationship,institutional system and social environment.The three factors have an impact on defensive medicine through different mechanisms of action,which provides qualitative evidence for comprehensive analysis of factors in related studies of defensive medicine.

OBJECTIVE To enrich the polymethoxyflavonoid-rich fraction from Citri Reticulatae Pericarpium using D101 macro-porous resin,and further to analyse the chemical constituents using High-Performance Liquid Chromatography Quadrupole-Time-of-Flight Mass Spectrometry(HPLC-Q-TOF-MS).METHODS Citri Reticulatae Pericarpium extract was adsorbed on D101 macro-porous resin and then eluted with different concentrations of ethanol to enrich the polymethoxyflavonoid-rich fraction;the content of the major flavonoid components was determined by high-performance liquid chromatography(HPLC);and the components were further an-alysed by HPLC-Q-TOF-MS.RESULTS The established HPLC method for the simultaneous determination of seven flavonoids in Citri Reticulatae Pericarpium extract was accurate and reliable.The contents of compounds such as nobiletin and tangeritin were signifi-cantly increased in the polymethoxyflavonoid-rich fraction.Using high resolution mass spectrometry(HRMS),70 and 60 compounds were identified from the Citri Reticulatae Pericarpium extract and the polymethoxyflavonoid-rich fraction,respectively,with 53 polyme-thoxyflavonoids being detected in these two extracts.CONCLUSION The results of this study provide an experimental basis for fur-ther identification of the pharmacological substance basis of the polymethoxyflavonoids in Citri Reticulatae Pericarpium and the estab-lishment of quality control methods.

Abstract: Objective To investigate the expression of T cell immunoglobulin and mucin domain-containing protein 3 (Tim-3) on the surface of T cells in patients with brucellosis (Bm), as well as the expression of interleukin-10 (IL-10) and transforming growth factor beta (TGF-β) in serum, and to analyze the differential expression of these indicators in patients with acute and chronic brucellosis, in order to provide new approaches for the differential diagnosis of acute and chronic brucellosis. Methods A total of 56 patients diagnosed with brucellosis at the First Affiliated Hospital of Xinjiang Medical University from April 2023 to September 2023 were selected, including 31 patients in the acute phase and 25 patients in the chronic phase. Additionally, 35 healthy individuals underwent routine physical examinations within the same period served as healthy controls. Flow cytometry was used to detect and compare Tim-3 levels on the CD4+ T cells' surface among the groups. Levels of serum IL-10 and TGF-β were measured and compared using CBA and ELISA, respectively, and the relationship of these factors with the staging of brucellosis patients was analyzed. Results The proportions of Tim-3+CD3+CD4+T cells in the control group, acute group, and chronic group were (2.56±1.25)%, (5.14±1.98)%, and (13.66±2.66)%, respectively. The Tim-3 levels in the patients with brucellosis were higher than those in the healthy control group, with the chronic group showing even higher levels, and these differences were statistically significant (P<0.05). The levels of IL-10 and TGF in the patient group were higher than those in the healthy control group, with the chronic group exhibiting significantly higher levels of IL-10 and TGF-β than the acute group, also presenting statistically significant differences (P<0.05). The areas under the ROC curve for predicting chronic brucellosis with Tim-3, IL-10, and TGF-β scores were 0.876, 0.865, and 0.663, respectively. Conclusions There are certain differences in the expression of Tim-3, serum IL-10, and TGF-β among patients with brucellosis, with high expression indicating a potential transition to the chronic phase of the disease. Tim-3 has shown the best diagnostic performance. Therefore, as a diagnostic indicator, Tim-3 may provide new ideas and strategies for the treatment and differential diagnosis of brucellosis.
