Prospective Study on the Association Between Blood Heavy Metal Levels and Pulmonary Function in University Students from a Medical College in Shandong Province, China.

Background: This study aimed to examine the blood concentrations of selected heavy metals, their corresponding pulmonary functions, and their interrelationship with university students.

Methods: This prospective study, conducted from September 2019 to September 2020, encompassed 593 university students. Participants completed self-administered questionnaires regarding demographic factors and underwent lung function testing and blood mercury analysis at two distinct intervals: an initial assessment and a follow-up examination.

Blood chromium and lung function among Chinese young adults: A comprehensive analysis based on epidemiology and metabolomics.

Chromium (Cr) exposure is associated with various respiratory system diseases, but there are limited studies investigating its impact on lung function in young adults. The Cr exposure-related metabolomic changes are not well elucidated. This study recruited 608 students from a university in Shandong Province, China in 2019.

Exposure to blue space surroundings and depressive symptoms in young Chinese adults: The mediating role of sleep.

Objective: Existing evidence suggests that the natural environment can influence mental health. However, limited research has focused on the relationship between blue space and depressive symptoms in young adults. To investigate the association between blue space surroundings and depressive symptoms in young adults in China and explore the underlying mechanisms.

Whole blood cadmium levels and depressive symptoms in Chinese young adults: A prospective cohort study combing metabolomics.

Objectives: To investigate the association between Cd exposure and depressive symptoms in Chinese young adults. And to investigate the potential metabolic changes associated with high blood Cd concentrations.

Methods: We conducted a cohort study in 2019 and 2021.

Factors Influencing Noise Following Primary Ceramic-on-Ceramic Total Hip Arthroplasty.

Background: The noise associated with ceramic-on-ceramic (CoC) total hip arthroplasty (THA) has been a concerning issue, while its underlying causes remain unclear.

Methods: We conducted a retrospective analysis of 119 patients (174 primary CoC THAs) who had a mean follow-up of 28 months (range, 12 to 106). A questionnaire was designed to collect information on nature, frequency, onset, duration, and impact of the noise.

The Relationship between Self-Perceived Burden and Posttraumatic Growth among Colorectal Cancer Patients: The Mediating Effects of Resilience.

At present, the influence factors of posttraumatic growth (PTG) in colorectal cancer (CRC) patients and the relationship between PTG, self-perceived burden (SPB), and resilience are not completely clear. Thus, the present study examined whether resilience and SPB could predict PTG in CRC patients. The role of resilience as a potential mediator was also assessed.

[Gene knockout technology and its application in the study of the relationship between mitochondrial dynamics and insulin resistance].

Mitochondrial dynamics, the processes of mitochondrial fusion and fission maintain homeostasis, are precisely regulated by fusion/fission-related proteins, and play an important physiological role in mitochondrial metabolism, quality and function. The aberrant changes of these proteins can trigger mitochondrial dynamics imbalance, which cause mitochondrial dysfunctions and result various disease states. This article focuses on gene knockout technology, and reviews the role and application progress of genes encoding for fusion and fission knockout mice in insulin resistance researches, in order to lay a foundation for future studies on signal transduction mechanism of mitochondrial dynamics imbalance in insulin resistance.

Validation of an information-motivation-behavioral skills model of upper limb functional exercise adherence among Chinese postoperative patients with breast cancer.

Background: The adherence to postoperative upper limb functional exercise in breast cancer (BC) patients is poor which can lead to adverse health outcomes. Effective intervention content to improve adherence is still unclear. The information-motivation-behavioral skills (IMB) model is a theoretical model that has been widely used to promote health behavior in many disease populations and may, therefore, help to explain and promote adherence to functional exercise.
