Objective:To investigate the role and possible mechanism of tripartite motif-containing protein 72 (Trim72) in acute viral myocarditis (AVMC) in mice.Methods:A mouse model of AVMC was established by intraperitoneal injection of Coxsackievirus B3 (CVB3, 2.0 × 10 5 PFU/mouse). Forty mice were randomly divided into the negative control (NC) + phosphate-buffered saline (PBS) group (NC+PBS group), Trim72 overexpression + PBS group (Trim72 + PBS group), NC + CVB3 group, and Trim72 + CVB3 group ( n = 10). Fourteen days before modeling, mice in each group were injected with adeno-associated virus type 9 vector (AAV9) encoding either negative control or Trim72 overexpression (5.0 × 10 11 VG/mouse) via tail vein. Subsequently, PBS or CVB3 was injected intraperitoneally in the PBS and CVB3 groups, respectively. After seven days, the surviving mice were euthanized, and the heart and serum samples were collected. HE and TUNEL staining were used to observe the cardiac pathological changes and cardiomyocyte apoptosis, respectively. The mRNA expression levels of Trim72 and pro-inflammatory cytokines TNF-α, IL-6, and IL-1β in myocardial tissues of each group were detected by RT-qPCR. The protein levels of cTnI, TNF-α, IL-6, and IL-1β in serum were detected by ELISA. The expression levels of Trim72, apoptosis-related proteins (Bax, Bcl-2, Cleaved caspase-3, Caspase-3), TLR4, p-p65, and p65 were detected by Western blot. Results:The protein and mRNA expression levels of Trim72 in myocardial tissues of mice in the NC+CVB3 group were significantly downregulated compared with those in the NC + PBS group ( P<0.05). Compared with the NC + CVB3 group, Trim72 overexpression significantly increased the protein and mRNA expression of Trim72 in myocardial tissues ( P<0.05), ameliorated myocardial inflammatory injury, decreased the apoptotic index of cardiomyocytes ( P<0.05), and reduced the levels of pro-inflammation cytokines TNF-α, IL-6, and IL-1β in the myocardium and serum ( P<0.05). Additionally, Trim72 overexpression also downregulated the protein expression of Bax, Cleaved caspase-3/Caspase-3, TLR4, and p-p65, and upregulated the protein expression of Bcl-2 in myocardial tissues ( P<0.05). There was no significant difference in the indexes of mice between the NC + PBS and Trim72 + PBS groups ( P>0.05). Conclusions:Trim72 overexpression attenuates AVMC in mice by inhibiting myocardial inflammatory injury and apoptotic imbalance, and the mechanism may be related to the negative regulation of the TLR4/NF-κB signaling pathway.

Objective:To explore the application effect of family nursing based on Noddings′ caring education theory in children with bronchopneumonia, so as to provide reference for clinical nursing of children with bronchopneumonia.Methods:A randomized controlled study was conducted, 120 children with bronchopneumonia admitted to Anqing Municipal Hospital from August 2023 to March 2024 were enrolled as the research objects by convenience sampling method. According to random number table method, they were divided into the control group and the experimental group. The control group was given routine nursing, while the experimental group was given family nursing based on Noddings′ caring education theory on the basis of routine nursing. The symptoms remission (disappearance time of cough and wheezing), length of hospital stay, lesion absorption, compliance of aerosol inhalation, treatment compliance, etc in 2 groups were observed.Results:A total of 60 children with bronchopneumonia were included in the control group, including 37 males and 23 females, aged (5.75 ± 1.09) years old, and 60 cases were included in the experimental group, including 36 males and 24 females, aged (5.65 ± 1.06) years old. The disappearance time of cough and wheezing, and length of hospital stay in the experimental group were (5.98 ± 0.61), (4.31 ± 0.45), (5.50 ± 0.65) d, which were shorter than (6.21 ± 0.63), (4.52 ± 0.46), (6.38 ± 0.89) d in the control group, the differences were statistically significant ( t = 2.03, 2.53, 6.19, all P<0.05). The lesion absorption rate and compliance of aerosol inhalation in the experimental group were 95.00% (57/60) and 91.67% (55/60), higher than 83.33% (50/60) and 76.67% (46/60) in the control group, the differences were statistically significant ( χ2 = 4.23, 5.07, both P<0.05). The scores of treatment compliance (medication according to time and dosage, moderate exercise, reasonable diet, self-care) in the experimental groups were (4.02 ± 0.41), (3.39 ± 0.37), (3.87 ± 0.48), (3.13 ± 0.37) points, higher than (3.82 ± 0.39), (3.25 ± 0.35), (3.68 ± 0.45), (2.97 ± 0.34) points in the control group, the differences were statistically significant ( t value were 2.13-2.74, all P<0.05). Conclusions:Family nursing based on Noddings′ caring education theory is beneficial to alleviate clinical symptoms and medical fear, improve compliance of aerosol inhalation and treatment compliance in children with bronchopneumonia.

Objective To establish a regression equation for risk factors of refeeding syndrome (RFS) in critically ill elderly patients and analyze the relevant intervention measures. Methods Clinical materials of 154 critically ill elderly patients treated in Intensive Care Unit (ICU) from January 2021 to March 2023 were retrospectively analyzed, and they were divided into RFS group (n=51) and non-RFS group (n=103) according to incidence condition of RFS. The influencing factors of RFS were analyzed by Logistic regression model; the predictive values of predictors for RFS were analyzed by receiver operating characteristic (ROC) curve; the relevant Logistic regression equations were constructed and verified, and relevant nursing interventions were formulated. Results The incidence of RFS in critically ill elderly patients was correlated with the Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, the Nutritional Risk Screening 2002 (NRS2002) score, invasive mechanical ventilation, fasting time before feeding, D-dimer level, nutritional intake methods, and pre-feeding blood phosphorus, potassium and magnesium levels (P < 0.05). Logistic regression analysis showed that APACHE Ⅱ score, NRS2002 score, nutrient intake methods and pre-feeding blood phosphorus and potassium levels were the independent risk factors of RFS in critically ill elderly patients (P < 0.05). The ROC curve results showed that the values of area under the curve (AUC) of APACHE Ⅱ score, NRS2002 score, nutritional intake methods, pre-feeding blood phosphorus and potassium levels, and the combined predictor in predicting the incidence of RFS in critically ill elderly patients were 0.754, 0.723, 0.707, 0.783, 0.774 and 0.859, respectively (P < 0.05). The Logistic regression equation for RFS was as follow: L=0.085×APACHE Ⅱ score-0.337×NRS 2002 score+0.537×nutrient intake methods-0.776×pre-feeding blood phosphorus level-0.207×pre-feeding blood potassium level+0.942. The predictive value of this equation was good, and targeted nursing interventions could be formulated based on this equation. Conclusion The regression equation of risk factors can be used for clinical prediction of the RFS risk in critically ill elderly patients, and clinical nursing interventions can be formulated based on the regression equation to prevent the occurrence of RFS.
