Background: Supraclavicular and infraclavicular nerve block are commonly used for the analgesia of distal arm surgeries, and this meta-analysis aims to compare their analgesic efficacy for distal arm surgeries.

Methods: We searched several databases including PubMed, Embase, Web of Science, EBSCO, and Cochrane library databases, and selected the randomized controlled trials exploring the analgesic efficacy of supraclavicular block versus infraclavicular block for distal arm surgeries. This meta-analysis was conducted using the random-effect or fixed-effect model based on the heterogeneity.

Thermosensitive Micelles Gel to Deliver Quercetin Locally for Enhanced Antibreast Cancer Efficacy: An In Vitro Evaluation.

Although quercetin is low cytotoxicity to normal human cells, quercetin is effective against the growth of some tumors. Given the poor blood stability in vivo, insolubility, low delivery efficiency, and poor medicinal properties of quercetin, we developed a local drug delivery system comprising quercetin core's polymer micelles and F127 hydrogel stroma. In vitro evaluation revealed that quercetin core's polymer micelles have excellent antitumor activity and could inhibit the multiplication of 4T1 breast cancer cells through the apoptosis pathway.

Biomechanical analysis of adjacent segments after correction surgery for adult idiopathic scoliosis: a finite element analysis.

The rising roles of exosomes in the tumor microenvironment reprogramming and cancer immunotherapy.

Exosomes are indispensable for intercellular communications. Tumor microenvironment (TME) is the living environment of tumor cells, which is composed of various components, including immune cells. Based on TME, immunotherapy has been recently developed for eradicating cancer cells by reactivating antitumor effect of immune cells.

Causal effect of education on bone mineral density: A Mendelian randomization study.

Education level may have some association with the incidence of osteoporosis, but it is elusive if this association is causal. This two-sample Mendelian randomization analysis focused on the causal effect of education level on femoral neck bone mineral density (FN-BMD), forearm BMD, lumbar spine BMD, and heel BMD. Twelve single nucleotide polymorphisms were used as instrumental variables.

Arthroscopic Lateral Meniscus Root Repair With Reverse Suture Anchor Technique.

The stability of the knee joint is crucially dependent on the integrity of the lateral meniscus posterior root, which is often accompanied by anterior cruciate ligament injury. Anchor suture repair for lateral meniscus posterior root injury not only achieves better biomechanical effects but also ensures favorable prognosis. However, the placement of anchors often requires the establishment of a posterior approach, and the insertion of an anchor is a technical challenge.

Potential role of ɛ4 allele as a modifier for the association of Val66Met polymorphisms and cognitive impairment in community-dwelling older adults.

Objective: To determine whether the brain-derived neurotrophic factor () Val66Met polymorphism is associated with cognitive impairment (CI) in community-dwelling Chinese older adults, and to investigate whether this relationship is modified by the Apolipoprotein E () ɛ4 allele.

Methods: The study is a secondary analysis of 703 participants aged ≥60 years randomly enrolled from the Beijing Longitudinal Study of Aging II prospective cohort. The education-adjusted Mini-Mental State Examination and the Clinical Dementia Rating Scale were used to measure the cognitive performance of the subjects.

SQLE is a promising prognostic and immunological biomarker and correlated with immune Infiltration in Sarcoma.
