Cumulative ecological risk and problematic smartphone use among Chinese college students: the roles of performance goal orientation, learning goal orientation and psychological resilience.

Problematic smartphone use (PSU) has emerged as a pressing concern among college students, with cumulative ecological risk identified as a crucial yet enigmatic contributor. To unravel its underlying mechanisms, we devised and validated a model that delves into the mediating roles of performance and learning goal orientations, as well as the moderating influence of psychological resilience. Our investigation encompassed 2011 Chinese college students spanning from freshmen to seniors, aged 16 to 25, utilizing comprehensive scales to assess various constructs.

Electroacupuncture alleviates acute myocardial ischemic injury in mice by regulating the β adrenergic receptor and post-receptor protein kinase A signaling pathway.

Fear of missing out and problematic smartphone use among Chinese college students: The roles of positive and negative metacognitions about smartphone use and optimism.

Background: Problematic smartphone use (PSU) has become a common phenomenon among college students. Fear of missing out (FoMO) is an important factor affecting PSU, but how FoMO affects PSU is not clear. Therefore, the mediating effect of positive and negative metacognitions about smartphone use (PMSU and NMSU) and the moderating effect of optimism are explored.

Study on the Prediction Model of Wound Infection After Spinal Fusion and Internal Fixation Based on Logistic Regression.

With the development of the times, spinal problems are not only one of the diseases that older people pay close attention to, but also gradually spread among teenagers. Therefore, it is very important to predict the possibility of wound infection in patients after spinal fusion and internal fixation. The method is to statistically analyze the clinical data of patients with clinical spinal disease, and to propose individualized treatment and recovery plan for each patient's pathological characteristics and postoperative recovery, so as to realize humanized service and minimize the possibility of wound infection.

Direct count of fluorescent microspheres in a microfluidic chip based on the capillary electrophoresis method.

Fluorescent microspheres (FMs) are tiny particles with special functions that are widely employed in biological research. Counting of microscale FMs is a great challenge by capillary electrophoresis. Herein we developed a method to count 2 μm FMs based on a microfluidic chip with a gradual change in inner size.

The Relationship Between Cumulative Ecological Risk and Problematic Smartphone Use Among Chinese College Students: Based on Latent Profile Analysis.

The aim of the current study is to explore the number of classes of cumulative ecological risk with latent profile analysis. Furthermore, the relationships between the classes of cumulative ecological risk and problematic smartphone use (PSU) among 2050 Chinese college students were researched.
