Methods: A retrospective analysis was conducted on 45 patients with extra-articular distal tibial fractures who underwent MIPO between January 2021 and December 2022. There were 20 males and 25 females, aged from 19 to 68 years (mean, 43.

Retrograde tibial intramedullary nail versus minimally invasive locking plate for extra-articular distal tibial fractures: a comparative and retrospective study.

Background: Distal tibial fractures represent common lower limb injuries, frequently accompanied by significant soft tissue damage. The optimal surgical approach for managing these fractures remains a topic of considerable debate. The aim of this study was to perform a comparative analysis of the outcomes associated with retrograde intramedullary tibial nails (RTN) and minimally invasive plate osteosynthesis (MIPO) in the context of treating extra-articular distal tibial fractures.

Platycodon D protects human nasal epithelial cells from pyroptosis through the Nrf2/HO-1/ROS signaling cascade in chronic rhinosinusitis.

Background: Pyroptosis has been demonstrated being closely associated with the inflammatory progression in chronic rhinosinusitis (CRS). However, platycodon D (PLD) has emerged as a key anti-inflammatory mediator in the inflammatory progression of various respiratory diseases. This study aims at investigating whether PLD could reduce inflammatory progression of CRS by inhibiting pyroptosis.

NIPBL-mediated RAD21 facilitates tumorigenicity by the PI3K pathway in non-small-cell lung cancer.

It is urgent to identify novel early diagnostic markers and therapeutic targets for non-small-cell lung cancer (NSCLC), which accounts for 85% of lung cancer cases and has a 5-year survival rate of 4-17%. Here, chromatin immunoprecipitation (ChIP) was used to identify DNA‒protein interactions, RNA methylation was determined by methylated RNA immunoprecipitation (MeRIP), RNA stability was tested by an RNA decay assay. We showed that RAD21, a member of the cohesin complex, is upregulated in NSCLC tissues and cell lines and found to be an independent prognostic factor for overall survival (OS) of NSCLC patients.

[Metabolomics of nasal lavage fluid in patients with allergic rhinitis treated by Xiaoqinglong Decoction].

This study used nasal lavage fluid for metabolomics to explore its feasibility, and applied it to the clinical metabolomics study of Xiaoqinglong Decoction in the treatment of allergic rhinitis(AR), aiming to investigate the molecular mechanism of Xiaoqing-long Decoction in the treatment of AR through differential changes in local nasal metabolism. AR patients were selected as the research subjects, and nasal lavage fluid was collected as the sample. Metabolomics analysis using liquid chromatography-mass spectrometry was performed on normal group, AR group, and Xiaoqinglong Decoction group.

[Treatment of Ideberg type scapular glenoid fracture with compression screw combined with Buttress plate through direct axillary approach].

Objective: To investigate the effectiveness of compression screw combined with Buttress plate through direct axillary approach for Ideberg typeⅡ scapular glenoid fractures.

Methods: A retrospective analysis was conducted on 11 patients with Ideberg type Ⅱ scapular glenoid fractures treated with compression screws combined with Buttress plate fixation through the direct axillary approach between January 2014 and June 2022. There were 7 males and 4 females, aged from 34 to 75 years, with an average of 56.

LncRNA PWRN2 promotes polycystic ovary syndrome progression via epigenetically reducing ATRX by recruiting LSD1.

Long non-coding RNA has been shown to mediate the progression of polycystic ovary syndrome (PCOS). However, the role and mechanism of Prader-Willi region nonprotein coding RNA 2 (PWRN2) in PCOS progression remain unclear. In our study, Sprague-Dawley rat was injected with dehydroepiandrosterone to mimic PCOS rat models.

Diagnosis and Treatment Strategy of Nasogenic Olfactory Dysfunction.

Since the global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a symptom of the onset of SARS-CoV-2, olfactory dysfunction (OD), has attracted tremendous attention. OD is not only a negative factor for quality of life but also an independent hazard and early biomarker for various diseases, such as Parkinson's and Huntington's diseases. Therefore, early identification and treatment of OD in patients are critical.

Antiviral Activity of -Hexenoic Acid against Coxsackievirus B and Enterovirus A71.

Enterovirus infections are life-threatening viral infections which occur mainly among children and are possible causes of viral outbreak. Until now, treatment and management of infections caused by members of the genus largely depended on supportive care, and no antiviral medications are currently approved for the treatment of most of these infections. The urgency of discovering new therapeutic options for the treatment of enterovirus infection is increasing.

HDAC Downregulation of Xiaoqinglong Decoction in the Treatment of Allergic Rhinitis.

Introduction: As one of the most common allergic diseases, allergic rhinitis (AR) has attracted wide attention all over the world. More appropriate treatment of AR should be explored thoroughly. In recent years, traditional Chinese medicine has attracted more attention in AR treatment.

In Situ Direct Monitoring of the Morphological Transformation of Single Au Nanostars Induced by Iodide through Dual-Laser Dark-Field Microscopy: Unexpected Mechanism and Sensing Applications.

Single nanoparticle imaging is a significant technique to help reveal the reaction mechanism and provides insight into the nanoparticle transformation. Here, we monitor the in situ morphological transformation of Au nanostars (GNSs) induced by iodide (I) in real time using dark-field microscopy (DFM) with 638 nm red (R) and 534 nm green (G) laser coillumination. The two lasers are selected because the longitudinal localized surface plasmon resonance of GNSs is located at 638 nm and that for GNSs after transformation is at 534 nm.

Does Bird Diversity Affect Public Mental Health in Urban Mountain Parks?-A Case Study in Fuzhou City, China.

Intensified urbanization has caused a linear decline in the quality of urban biodiversity and indirectly harms our current human settlement environment. Urban mountain parks provide a refuge for the animals and plants and play a vital role in satisfying residents' lives. At present, few studies are focusing on the impact of biodiversity on human mental health benefits of urban mountain parks in high-density construction areas along the coast of the Eastern Hemisphere.

High-Throughput Color Imaging Hg Sensing via Amalgamation-Mediated Shape Transition of Concave Cube Au Nanoparticles.

Mercury, as one type of toxic heavy metal, represents a great threat to environmental and biological metabolic systems. Thus, reliable and sensitive quantitative detection of mercury levels is particularly meaningful for environmental protection and human health. We proposed a high-throughput single-particle color imaging strategy under dark-field microscopy (DFM) for mercury ions (Hg) detection by using individual concave cube Au nanoparticles as optical probes.
