Chronic refractory wound （CRW） presents significant clinical treatment challenges due to pathological characteristics such as persistent inflammation， bacterial infection， oxidative stress and inadequate angiogenesis. Astragali Radix， a traditional Chinese medicinal herb， exerts multi-target pharmacological effects on CRW through its active components， including Astragalus polysaccharides， flavonoids， and astragaloside Ⅳ， etc. Fundamental studies indicate that these components promote CRW healing by modulating inflammatory responses， inhibiting pathogen growth， improving antioxidant capacity and stimulating neovascularization. Network pharmacology and bioinformatics studies have revealed that active components of Astragali Radix target and modulate key signaling nodes such as nuclear factor-κB， phosphatidylinositol 3-kinase/Akt， AMP-activated protein kinase， and vascular endothelial growth factor receptor， as well as inflammation-angiogenesis-related pathways， thereby synergistically exerting anti-inflammatory and pro-angiogenic effect. Clinical applications have demonstrated that oral formulations （e.g.， Huangqi guizhi decoction， Danggui huangqi decoction， etc.） reduce healing time of CRW and lower inflammatory marker levels， while topical preparations （e.g.， Zizhu ointment， Huangqi shengji ointment， electrostatically spun Astragalus polysaccharide composite nanofibre dressings， etc.） significantly improve healing rates of CRW and minimize complications.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

OBJECTIVE: The compatibility of Eucommia ulmoides (Eu) and Psoralea corylifolia (Pc) on the pharmacokinetic (PK) properties in the rat was explored in this study. METHODS: Eu extract, Pc extract and the combined extracts (crude drug ratio was 2:1) was administered by gavage, respectively. Two PK experiments were conducted. In first one, the blood samples were collected via the occuli chorioideae vein to get the PK properties of the components. In second one, the blood samples were simultaneously collected via the internal jugular vein or portal vein at different time points and the concentrations of target ingredients were detected by LC/MS/MS to clear the location where the interaction of Eu and Pc took place in vivo. RESULTS: Eight of 11 ingredients in Eu and Pc extract were determined in rat plasma. The exposure levels of geniposidic acid (GPA), aucubin (AU), geniposide (GP), pinoresinol diglucoside (PDG), psoralen glycosides (PLG) and isopsoralen glycosides (IPLG) were decreased 1/5-2/3 after administration of combined extracts. Comparing to the combined administration, the exposure of GPA and AU in plasma of single Eu administration collected via the portal vein were decreased 1/3-2/3, and the values of AUC_0-24h and AUC_0-∞ of GP collected from the portal vein or internal jugular vein were double increased. The other components' parameters were not significantly changed. CONCLUSION In summary, the Pc and Eu combined administration could affect the exposure of the main components of Eu extract in rats due to the changed intestinal absorption. The research on the compatibility of Pc and Eu was helpful to guide the clinical administration of Eu and Pc simultaneously.

Objective To explore whether the capacity of decision-making under ambiguity in adult patients with moyamoya disease(MMD)is impaired and its association with executive function.Methods Neuropsychological scales were used to measure the executive function of forty-one adult patients with MMD and forty-one healthy con-trols(HC),The Iowa Gambling Task(IGT)was utilized to study the capacity of decision-making under ambiguity of the two groups.Correlation analysis was performed between the two types of data.Results ① The total number of favorable choices in the MMD group was significantly lower than that in the HC group,with a statistically signifi-cant difference(Z=-2.782,P＜0.01),and the total number of unfavorable choices was significantly higher than that of the controls,with a statistically significant difference(Z=-2.782,P＜0.01).The results of ANOVA showed that the net residual value of Block4 and Block5 in MMD group was lower than that of Block4 and Block5 in HC group,respectively,and the differences were statistically significant(t=-3.433,P=0.001;t=-5.271,P＜0.001),the net residual value of Block 1 was higher than that of Block 1 in HC group,the difference was statisti-cally significant(t=2.715,P=0.008).② Spearman correlation analysis revealed no association between the net score of IGT,the total number of favorable choices,the total number of unfavorable choices,and executive func-tion.Conclusion The capacity of decision-making under ambiguity in adult patients with MMD is impaired possi-bly,which is not correlated with executive cognition.
