Alternative Splicing of the NMDA Receptor Subunit GluN1 Mediated by Polypyrimidine Tract-Binding Protein Dimerization in the Trigeminal Ganglion Contributes to Orofacial Allodynia.

Orofacial neuropathic pain, a debilitating condition associated with trigeminal nerve injury, is often characterized by allodynia. N-methyl-d-aspartate receptors (NMDARs), particularly the GluN1 subunit, play a central role in mediating this pain. The GluN1 subunit undergoes alternative splicing at exon 5, generating isoforms GluN1a (lacking the exon 5-encoded N1 cassette) and GluN1b (retaining the N1 cassette), which have distinct functional roles.

Engineered RVG-exosomes-mediated delivery of siRNAs targeting NMDAR alleviates orofacial neuropathic pain by suppressing central sensitivity.

Orofacial neuropathic pain (NP) is a common complication in oral clinical practice that severely affects quality of life. However, NP does not currently receive effective medications. Engineered exosomes have great potential as drug delivery systems for treating diseases.

The synergistic effect of the triglyceride-glucose index and a body shape index on cardiovascular mortality: the construction of a novel cardiovascular risk marker.

Background: Insulin resistance, represented by increased triglyceride-glucose (TyG) index levels, shows interplay with visceral obesity and together promotes cardiovascular diseases and mortality. However, significant controversies exist regarding whether modified TyG indices, such as TyG-BMI, TyG-WC, and TyG-WHtR, outperform the TyG index in predicting cardiovascular outcomes. We aimed to explore whether there was a synergistic effect of a body shape index (ABSI), a better parameter reflecting visceral obesity, and the TyG index on cardiovascular mortality.

The crucial role of NR2A mediating the activation of satellite glial cells in the trigeminal ganglion contributes to orofacial inflammatory pain during TMJ inflammation.

Temporomandibular joint inflammatory diseases are a significant subtype of temporomandibular disorders (TMD) characterized by inflammatory pain in the orofacial area. The N-methyl-D-aspartate receptor (NMDAR), specifically the NR2A subtype, was crucial in neuropathic pain. However, the exact role of NR2A in inflammatory pain in the TMJ and the molecular and cellular mechanisms mediating peripheral sensitization in the trigeminal ganglion (TG) remain unclear.

The additive effect of the triglyceride-glucose index and estimated glucose disposal rate on long-term mortality among individuals with and without diabetes: a population-based study.

Background: The triglyceride-glucose (TyG) index and estimated glucose disposal rate (eGDR), which are calculated using different parameters, are widely used as markers of insulin resistance and are associated with cardiovascular diseases and prognosis. However, whether they have an additive effect on the risk of mortality remains unclear. This study aimed to explore whether the combined assessment of the TyG index and eGDR improved the prediction of long-term mortality in individuals with and without diabetes.

N-methyl-D-aspartate Receptor Subunits 2A and 2B Mediate Connexins and Pannexins in the Trigeminal Ganglion Involved in Orofacial Inflammatory Allodynia during Temporomandibular Joint Inflammation.

Temporomandibular joint osteoarthritis (TMJOA) is a severe form of temporomandibular joint disorders (TMD), and orofacial inflammatory allodynia is one of its common symptoms which lacks effective treatment. N-methyl-D-aspartate receptor (NMDAR), particularly its subtypes GluN2A and GluN2B, along with gap junctions (GJs), are key players in the mediation of inflammatory pain. However, the precise regulatory mechanisms of GluN2A, GluN2B, and GJs in orofacial inflammatory allodynia during TMJ inflammation still remain unclear.

Comparison of the effectiveness of probiotic supplementation in glucose metabolism, lipid profile, inflammation and oxidative stress in pregnant women.

By employing a network meta-analysis (NMA) approach, we compared the effectiveness of different probiotic supplementation strategies for pregnant women. : A comprehensive search across multiple databases was performed to identify studies comparing the efficacy of probiotic supplements with each other or the control (placebo) among pregnant women.

LncRNA Anxa10-203 enhances Mc1r mRNA stability to promote neuropathic pain by recruiting DHX30 in the trigeminal ganglion.

Background: Trigeminal nerve injury is one of the most serious complications in oral clinics, and the subsequent chronic orofacial pain is a consumptive disease. Increasing evidence demonstrates long non-coding RNAs (lncRNAs) play an important role in the pathological process of neuropathic pain. This study aims to explore the function and mechanism of LncRNA Anxa10-203 in the development of orofacial neuropathic pain.

Blood Group Antigen A Carriers Exhibit an Extended Progression-Free Survival with no more Immune-Related Adverse Events.

Extensive investigations have been conducted regarding the potential correlation between blood type and the immune system, as well as cancer risk in the Southern Chinese population. However, the prognostic value of the blood group and its genetic determinants in the context of immune checkpoint inhibitor (ICI) treatment remains unclear. Therefore, the associations between the ABO blood group and its single nucleotide polymorphisms (SNPs) were examined in relation to ICI treatment outcomes in 370 eligible patients with cancer.

Reconstruction of Buccal-penetrating Defects Using the Double-folded Lateral Arm Free Flap.

The reconstruction of buccal-penetrating defects remains challenging. The present study aims to explore the application value of the lateral arm free flap (LAFF) on the reconstruction of buccal-penetrating defects with the hope of providing a better option for clinical practice. Nineteen patients with this kind of issue posed by either tumor resections or deformities in the craniofacial regions were recruited in this study, and LAFF was employed to reconstruct these defects by double folding and individually designing the flap.

Clinical characteristics of patients with labyrinthine fistulae caused by middle ear cholesteatoma.

Background: Labyrinthine fistula (LF) is a very common clinical complication mainly caused by middle ear cholesteatoma. Whether the presence of different degree LF caused by middle ear cholesteatoma aggravates neurosensory hearing loss (NSHL) and what is the degree of the hearing loss caused by LF were still under controversial. This study aimed to investigate whether the LF degree is correlative with the age distribution, disease duration and hearing loss degree for cholesteatomatous patients.

Cutaneous neuroendocrine carcinoma of the external auditory canal: a case report and review of the literature.

Cutaneous neuroendocrine carcinoma (cNEC) is rarely seen in the external ear. In this paper, we newly describe a patient with cNEC in his right external auditory canal, followed by a further discussion on the clinical features, diagnosis, and treatments of cNEC of the external ear.
