Finite element analysis of three reconstruction strategies for AORI IIA tibial bone defects in TKA.

Background: AORI IIA-type bone defects are frequently encountered during total knee arthroplasty (TKA), posing a challenge for achieving durable and stable fixation. Although various reconstruction strategies have been proposed, the optimal method balancing mechanical stability and biological integration remains unclear.

Objective: This study aimed to evaluate and compare the biomechanical performance of three reconstruction techniques-locking plate fixation (LP Group), screw-assisted bone cement filling (SC Group), and metal block augmentation (MB Group)-for managing AORI IIA tibial defects using finite element analysis.

PCK1 as a potential hub gene in distinguishing lactate metabolism between rheumatoid arthritis and osteoarthritis.

Background: Lactate is notably involved in the advancement of rheumatoid arthritis (RA) and osteoarthritis (OA). Nevertheless, the causal association between these conditions and lactate remains uncertain. This study aims to use Mendelian randomization (MR) to investigate their relationship with lactate and understand the genetic differences in lactate metabolism between them.

Assessing effectiveness of ABCDE Framework for teaching condylar fracture reduction in dental education: a mixed methods study.

Background: Managing displaced proximal segments in mandibular condylar fractures remains challenging due to complex anatomy and limited surgical visibility. Conventional teaching methods in oral and maxillofacial surgery (OMFS) often inadequately address these challenges. This study evaluates the effectiveness of a novel ABCDE educational framework, based on the Technology Acceptance Model (TAM), in enhancing surgical training by improving procedural understanding, technical skill acquisition, and trainee confidence in managing these fractures.

Juanbi Qianggu Formula inhibits fibroblast-like synovicytes activation via repressing LncRNA ITSN1-2 to promote RIP2 K48 ubiquitination.

Background: Long non-coding RNA ITSN1-2(lncRNA ITSN1-2) promotes fibroblast-like synovicytes (FLS) proliferation and suppress apoptosis through activation of the NOD2/RIP2 signaling pathway, thereby exacerbating synovitis in Rheumatoid arthritis (RA) pathology. Juanbi Qianggu Formula (JBQG), a clinically efficacious traditional Chinese medicine, has shown significant efficiency in inhibiting FLS activation in RA and alleviating disease progression in RA patients. However, the molecular mechanism underlying JBQG's anti-arthritic effects remains incompletely understood, particularly regarding its potential to modulate lncRNA ITSN1-2-mediated NOD2/RIP2 signaling in FLS activation.

Study on the risk factors for colorectal polyp recurrence: a cross-sectional retrospective cohort study.

Objective: To investigate the factors associated with the recurrence of colorectal polyps.

A finite element analysis on the indication for extracting partially impacted mandibular third molars considering mandibular trauma.

Background: Patients presenting with partially impacted lower third molars (M3) have a higher likelihood of experiencing angle fractures while simultaneously decreasing the risk of condylar fractures. However, the specific biomechanical mechanism responsible for this occurrence remains unclear. Moreover, there is an ongoing debate regarding whether the removal of M3s might actually increase the risk of condylar fractures.

The aim of this study is to assess the influence of various Er:YAG laser energies on dentin surface micromorphology and dentine-resin shear bond strength (SBS). Eighty dentin specimens were prepared and divided randomly into ten groups: control group (CG), phosphoric acid-etched group (AG), four laser-conditioned groups treated with various pulse energies of 40, 60, 80, and 100 mJ (L40, L60, L80, L100), and four laser-conditioned acid-etched groups (LA40, LA60, LA80, LA100). Two specimens from each group underwent scanning electron microscopy examination, while the remaining six were subjected to the dentin-resin SBS test.

A systematic review and network meta-analysis of virtual reality, audiovisuals and music interventions for reducing dental anxiety related to tooth extraction.

Background: Tooth extraction is a common procedure performed by oral and maxillofacial surgeons or dentists, often resulting in dental fear and anxiety. The use of relaxing music, audiovisuals, and virtual reality (VR) technologies has been employed to reduce dental anxiety. This network meta-analysis (NMA) aimed to assess the comparative effectiveness of relaxing music, audiovisuals, and VR in reducing dental anxiety associated with tooth extraction.

Objective: This study aims to assess the efficacy of anchored sutures (AS) in securing the anterolateral thigh (ALT) flap during oral and oropharyngeal reconstructions, and its impact on the occurrence of orocutaneous fistula (OCF).

Materials And Methods: A retrospective study was performed on patients who underwent ALT flap reconstruction in our department in the year 2022. The patients were divided into two groups based on whether the AS technique was used.

Natural fulvic acids inhibit non-small-cell lung cancer through the COX-2/PGE2/EP4 axis: In silico and in vivo assessments.

Purpose: Non-small-cell lung cancer (NSCLC) is a major public health concern with a high incidence worldwide. Coal-derived fulvic acids (FAs) contain functional groups in their chemical structures. Overexpression of cyclooxygenases-2 (COX-2), prostaglandin E2 (PGE2), and the PGE2 receptor EP4 subtype (EP4) can have a potential link with the increased tumor incidence and promoted tumor growth and metastasis in NSCLC.

The effect of JuanBiQiangGu granules in combination with methotrexate on joint inflammation in rheumatoid arthritis: a randomized controlled trial.

Rheumatoid arthritis (RA) joint inflammation severely affects joint function and quality of life in patients and leads to joint deformities and limb disability. The non-steroidal anti-inflammatory drugs used in the treatment of RA do not fully control the progression of joint inflammation and bone destruction and have notable adverse reactions. Traditional Chinese medicine formula JuanBiQiangGu Granules (JBQG) are commonly used for the treatment of RA inflammation and delay of bone destruction, but has not been evaluated through high-quality clinical studies.

Precise Coronoidectomy and Zygomatic Arch Reduction for Unilateral Hyperplasia of the Coronoid Process (Jacob's Disease) via Computer-aided Design and Manufacture.

The Arabidopsis TETRATRICOPEPTIDE-REPEAT THIOREDOXIN-LIKE (TTL) family members are involved in root system formation via their interaction with cytoskeleton and cell wall remodeling.

Lateral roots (LR) are essential components of the plant edaphic interface; contributing to water and nutrient uptake, biotic and abiotic interactions, stress survival, and plant anchorage. We have identified the TETRATRICOPEPTIDE-REPEAT THIOREDOXIN-LIKE 3 (TTL3) gene as being related to LR emergence and later development. Loss of function of TTL3 leads to a reduced number of emerged LR due to delayed development of lateral root primordia (LRP).

[Role of hydrogen sulfide mediated autophagy related genes in intestinal function injury of sepsis].

Sepsis is an organ dysfunction that endangers a patient's life caused by an imbalanced infection response, and is a clinically critical illness. Despite a deep understanding of the pathogenesis of sepsis, there has been no significant improvement in sepsis mortality during clinical treatment at home and abroad. In recent years, the role of autophagy in the pathogenesis of sepsis has become a new research point in the field of medical research.
