In cardiovascular disorders, neurological diseases, and chronic metabolic diseases, the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway is essential for maintaining cell homeostasis. According to studies, boosting Nrf2 expression can be used to cure or prevent chronic diseases that are characterized by oxidative stress, inflammation, and mitochondrial dysfunction. Nonalcoholic fatty liver disease (NAFLD) is a chronic metabolic liver disease characterized by hepatic steatosis brought on by a number of causes other than alcohol. In recent years, its incidence has gradually risen across the globe. According to relevant studies, NAFLD and the Nrf2 signaling pathway are tightly connected. Inhibiting lipid production and metabolism-related enzymes, repairing impaired liver metabolism, and lowering hepatic lipid storage are all possible with Nrf2 activation. Exercise is a powerful tool for treating and preventing NAFLD. However, exercise type, exercise intensity, environment, and exhaustion all have an impact on the Nrf2 signaling pathway. By activating Nrf2, exercise can lessen liver inflammation, oxidative stress, endoplasmic reticulum stress, and insulin resistance, and ameliorate liver damage to improve NAFLD. The activation of Nrf2 signaling pathway, its associated mechanism of controlling antioxidation, and the impact of exercise on the Nrf2 signaling pathway are all explained in this work. Based on the pathogenesis of NAFLD, this article examines the connection between exercise, Nrf2, and NAFLD, and the current state of knowledge regarding Nrf2’s role in the amelioration of NAFLD through exercise. It offers a theoretical frame of reference for future research into how Nrf2 might be used to improve NAFLD.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective To explore the correlation between the self-management and self-efficacy of senile patients with chronic heart failure (CHF). Methods In this study, the conveninent sampling method was adopted. From June to December 2016, totally 416 senile CHF patients hospitalized in the Department of Cardiology of 5 general class Ⅲ grade A hospitals in Xi'an were investigated with the general demographic data questionnaire, self-management scale for CHF patients and chronic disease self-efficacy scale. Results The score of self-management in the senile CHF patients in Xi'an totaled (50.76±9.98), with a scoring rate of 63.5%; the scores of medication management, food and beverage management, psychological and social management and symptom management were (13.38±3.38), (7.89±2.14), (12.81±2.91) and (16.69±4.26), with the scoring rates of 66.9%, 65.8%, 64.1% and 59.6%, respectively, showing a medium level; and there was statistically significant difference in the total self-management score between patients with different marital status, per capita income and heart function grading (t=-2.443, 10.906, 16.229;P<0.05). The score of self-efficacy totaled (34.30±11.90), with a scoring rate of 57.17%, showing a medium level. The correlation analysis showed that there was a positive correlation between self-efficacy and self-management (r=0.161, P< 0.05). Conclusions The self-management and self-efficacy of the senile CHF patients in Xi'an remain at a medium level, which could be possibly improved, and the two are closely correlated. The results suggest that we should pay more attention to the patient's management confidence in the disease itself, attach importance to their psychological and social support and enhance their self-efficacy, thus improving their self-management. This is of great significance in controlling CHF and improving the patient's quality of life.
