Efficacy and safety of non-ablative vs. ablative lasers for acne scarring: A meta-analysis.

Acne scarring significantly affects physical appearance and psychological well-being, prompting the exploration of various treatment options, including ablative and non-ablative laser therapies. The debate around their efficacy and safety persists, underscoring the need for a comprehensive analysis. This meta-analysis compares the therapeutic outcomes and safety profiles of ablative and non-ablative laser treatments for acne scars, based on a comprehensive review of clinical trials conducted up to March 2023.

KLF5 enhances CXCL12 transcription in adipose-derived stem cells to promote endothelial progenitor cells neovascularization and accelerate diabetic wound healing.

Background: Adipose-derived stem cells (ADSCs) have been shown to accelerate diabetic wound healing by promoting neovascularization, though the underlying mechanisms are not fully understood. This study aims to explore whether ADSCs influence endothelial progenitor cells (EPCs) function to enhance diabetic wound healing.

Methods: Human adipose-derived stem cells (hADSCs) were isolated from patient adipose tissue and cultured under normal and high glucose (HG) conditions.

The chain mediation effects of self-confidence and positive coping style on academic satisfaction and professional identity among Chinese medical students.

Due to the importance of medical students in the buildup of the health system and the influence of professional identity in their study, the aim of the study is to focus on the impact of academic satisfaction and professional identity on Chinese medical students during their career transformation, taking into consideration other factors that play a role in this relationship. 735 junior and senior medical university students from two training hospital were surveyed by using a cluster sampling method. The questionnaire included academic satisfaction scale, career transition psychological scale, simple coping style questionnaire and professional identity questionnaire.

Research progress and application prospect of adipose-derived stem cell secretome in diabetes foot ulcers healing.

Diabetic foot ulcers (DFUs) are chronic wounds and one of the most common complications of diabetes, imposing significant physical and mental burdens on patients due to their poor prognosis and treatment efficacy. Adipose-derived stem cells (ADSCs) have been proven to promote wound healing, with studies increasingly attributing these beneficial effects to their paracrine actions. Consequently, research on ADSC secretome as a novel and promising alternative for DFU treatment has been extensively conducted.

The chain mediating roles of anxiety and depression in the relationship between the effects of the COVID-19 pandemic and procrastination in adolescents: a longitudinal study.

Background: The relationship between the Coronavirus Disease 2019 (COVID-19) pandemic, which is a traumatic event for adolescents, and procrastination is not clear. Mental health may play an important role in this relationship; however, the underlying mechanisms remain unknown. This study aimed to construct chain mediation models to examine whether anxiety and depression symptoms mediate the effects of the COVID-19 pandemic on procrastination in adolescents.

Trajectories and influencing factors in adolescent procrastination behavior throughout the COVID-19 pandemic: a four-wave prospective longitudinal study.

Background: Despite the growing attention given to adolescent behavior problems, little is known about the trajectories and factors that have influenced adolescent procrastination during the COVID-19 pandemic. This study monitors changes in procrastination behavior among Chinese adolescents during the pandemic and identifies vulnerable groups.

Methods: A four-wave study using a representative sample of 11-to 18-year-olds in China was conducted, with baseline data collected in June 2020 ( = 4,156; 49% girls) and follow-ups in December 2020 ( = 3,392; 50% girls), August 2021 ( = 2,380; 48% girls), and October 2021 ( = 1,485; 49% girls).

Association of the Combined Effects between Insulin-Like Growth Factor-1 Gene Polymorphisms and Negative Life Events with Major Depressive Disorder among Chinese population in the Context of Oxidative Stress.

Background: Oxidative stress may be increased in a number of psychiatric disorders, including major depressive disorder (MDD). MDD has been shown to be related to insulin-like growth factor-1 (IGF-1) as well as to negative life events; exploring the interaction of IGF-1 polymorphisms and negative life events on the risk of MDD is needed. The aim of this study was to analyze the single and combined effects of IGF-1 polymorphisms (rs972936 and rs978458) and negative life events with MDD among Chinese population.
