Association between bedroom night light exposure during sleep and children s emotional symptoms / 中国学校卫生

Objective@#To explore the association between exposure to bedroom night light during sleep and emotional symptoms in children and provide a scientific basis for subsequent effective prevention and intervention.@*Methods@#In December 2021, 1 926 students from grades 4 to 6 were recruited to conduct a student questionnaire survey in two primary schools in Tianchang of Chuzhou City, Anhui Province. The data, including general demographic information, use of night lights and curtains, emotional symptoms, and other information, was collected. Binary Logistic regression analysis was used to examine the correlation between night light use and children s emotional symptoms.@*Results@#The reporting rates of depression symptoms, generalized anxiety symptoms, social phobia, and obsessive compulsive symptoms of the children were 2.5%, 2.6%, 3.4% and 2.5%, respectively. About 12.6% of children often sleep with a night light on, and 22.0% of children did not close the curtains. Binary Logistic regression analysis revealed that frequent sleep with night lights was associated with an increased risk of depression symptoms( OR=2.29, 95%CI = 1.04- 5.03), social phobia ( OR=1.93, 95%CI =1.02-3.64) and obsessivecompulsive symptoms ( OR=3.44, 95%CI =1.72-6.88) in children( P < 0.05).@*Conclusion@#There is a positive correlation between bedroom night light exposure during sleep and the detection rate of children s emotional symptoms. The attention should be paid to bedroom light environment of children during sleep to reduce the adverse effects of night light exposure on the mental health.

4D bioprinting technology and its application in cardiovascular tissue engineering / 生物工程学报

3D bioprinting technology is a rapidly developing technique that employs bioinks containing biological materials and living cells to construct biomedical products. However, 3D-printed tissues are static, while human tissues are in real-time dynamic states that can change in morphology and performance. To improve the compatibility between in vitro and in vivo environments, an in vitro tissue engineering technique that simulates this dynamic process is required. The concept of 4D printing, which combines "3D printing + time" provides a new approach to achieving this complex technique. 4D printing involves applying one or more smart materials that respond to stimuli, enabling them to change their shape, performance, and function under the corresponding stimulus to meet various needs. This article focuses on the latest research progress and potential application areas of 4D printing technology in the cardiovascular system, providing a theoretical and practical reference for the development of this technology.

Association of metabolic syndrome with chronic kidney disease in premenopausal and postmenopausal women / 南方医科大学学报

OBJECTIVE@#To explore the relationship between metabolic syndrome (MS) and the risk for chronic kidney disease (CKD) in premenopausal and postmenopausal women.@*METHODS@#We conducted a cross-sectional study among 1346 community-based women from June to October 2012 and collected the data of personal history, lifestyle, physical measures and laboratory indicators. The diagnosis of CKD was established for an eGFR of less than 60 mL/min per 1.73 m or albuminuria. The diagnosis of metabolic syndrome was based on the International Diabetes Federation Guide. According to an epidemiological survey in Guangdong province, women older than 48.9 years were classified as having a postmenopausal status. The prevalence of MS and CKD was determined in both the premenopausal and postmenopausal women, and the association between MS and CKD was analyzed using logistic regression models.@*RESULTS@#MS was significantly correlated with CKD in premenopausal women in both unadjusted analyses (OR=3.10, 95% : 1.32-7.28, =0.009) and in analysis after adjustment for potential confounders (OR=4.09, 95% : 1.63- 10.32, =0.003). When adjusted for diabetes, hypertension, and hyperuricemia, no correlation was found between MS and CKD in premenopausal women (OR=1.56, 95% : 0.31-7.63, = 0.592); in the unadjusted analyses, MS was significantly correlated with CKD in postmenopausal women ( < 0.001). After further adjustment for age, education status, current smoking, physical inactivity, and current drinking, MS was still significantly correlated with CKD (OR=2.60, 95% : 1.69-3.99, < 0.001). When adjusted for diabetes, hypertension, and hyperuricemia, the correlation between MS and CKD was still significant (OR=1.61, 95% : 1.09-2.37, =0.018). In the unadjusted model, a high blood pressure (OR=2.77, 95%CI: 1.57-4.89, < 0.001), an elevated serum triglyceride level (OR=1.84, 95%: 1.16-2.90, =0.009) and a high fast glucose level (OR=2.07, 95%: 1.30-3.28, =0.002) were all significantly correlated with CKD in postmenopausal women. After adjusting for age, current smoking, current alcohol use, education status and physical inactivity, a high blood pressure (OR=2.28, 95%: 1.22-4.26, =0.01), a high serum triglyceride level (OR=1.71, 95%: 1.03-2.86, =0.039) and a high fast glucose (OR=2.25, 95%: 1.36-3.73, =0.002) were still significantly correlated with CKD in postmenopausal women. Blood pressure, serum triglyceride level, fast glucose, serum HDL cholesterol level and central obesity were not correlated with CKD in either the unadjusted model or adjusted model in premenopausal women ( > 0.05).@*CONCLUSIONS@#MS is correlated with CKD in both premenopausal and postmenopausal women, and the association is dependent on diabetes, hypertension, and hyperuricemia in premenopausal women but not in postmenopausal women.
