Objective:To study and analyze the status quo and influencing factors of breast cancer patients′ concern about the upbringing of their minor children, and to provide a reference for clinical improvement of the level of breast cancer patients′ concern about parenting.Methods:A total of 247 breast cancer patients in the daytime ward of Tianjin Medical University Cancer Hospital from March to May 2023 were selected by convenience sampling. The General Information Questionnaire, Parenting Concerns Questionnaire, Parenting Sense of Competence Scale were selected for cross-sectional investigation. The multiple linear regression model was used to analyze the influencing factors of breast cancer patients′ worries about the upbringing of their minor children.Results:Finally, 240 valid questionnaires were ultimately collected. There were 12 patients with breast cancer aged 20-29 years old, 76 patients aged 30-39 years old, 117 patients aged 40-49 years old, and 35 patients aged ≥50 years old. The total score of breast cancer patients′anxiety about minor children′s rearing was (37.34 ± 2.56) points. The scores of each dimension were in order of (15.14 ± 1.02) worry about the actual impact on children, (11.15 ± 0.83) worry about the emotional impact on children, and (11.05 ± 0.71) worry about the parents of children. The total score of parenting competence (66.54 ± 11.68) points. Multiple linear regression analysis showed that parenting competence, educational level, number of underage children, per capita monthly income of families, and TNM stage (T: tumor primary lesion; N: regional lymphnode involvement; M: remote metastasis situation) affected parenting anxiety ( t values were -15.24-8.56, all P<0.05), which could explain 81.2% of the total variation in parenting anxiety level. Conclusions:Breast cancer patients′ concern about the upbringing of minor children is at a medium level, so medical staff should give relevant intervention measures to breast cancer patients with different characteristics, in order to provide reference for reducing the level of concern about the upbringing of minor children.

Objective: To investigate the role of Portulaca oleracea (POL) in promoting revascularization and re-epithelization as well as inhibiting iron aggregation and inflammation of deep tissue pressure injury (DTPI). Methods: The hydroalcoholic extract of POL (P) and aqueous phase fraction of POL (PD) were prepared based on maceration and liquid–liquid extraction. The number of new blood vessels and VEGF-A expression level were assessed using H&E stain and Western blot on injured muscle to examine the role of POL different extracts in vascularization. The iron distribution and total elemental iron of injured muscle were detected using laser ablation inductively coupled plasma mass spectrometry (ICP-MS) and Perls’ staining to determine whether POL extracts can inhibit the iron accumulation. Besides, the ability of POL extracts to promote wound healing by combining re-epithelization time, inflammation degree and collagen deposition area were comprehensively evaluated. Results: In vitro, we observed a significant increase in HUVEC cell viability, migration rate and the number of the tube after P and PD treatment (P < 0.05). In vivo, administration of P and PD impacted vascularization and iron accumulation on injured tissue, evident from more new blood vessels, higher expression of VEGF-A and decreased muscle iron concentration of treatment groups compared with no-treatment groups (P < 0.05). Besides, shorter re-epithelization time, reduced inflammatory infiltration and distinct collagen deposition were associated with administration of P and PD (P < 0.05). Conclusion: POL extract administration groups have high-quality wound healing, which is associated with increased new blood vessels, collagen deposition and re-epithelization, along with decreased iron accumulation and inflammatory infiltration. Our results suggest that that POL extract is beneficial to repair injured muscle after ischemia–reperfusion, highlighting the potential of POL in the DTPI treatment.
