Clinical effects of twin-block combined with maxillary expansion on the upper airway in adolescents with Class II malocclusion.

Background: Class II malocclusion, particularly class II division 1, poses a significant orthodontic challenge with implications for both aesthetics and health. This study aimed to explore the impact of twin-block (TB) combined with maxillary expansion treatment (TB-ME) on upper airway dimensions and inflammatory profiles in adolescents with skeletal Class II Division 1 malocclusion in adolescent.

The effect of food on the pharmacokinetics of Sutetinib maleate capsule, an irreversible EGFR tyrosine kinase inhibitor, in healthy Chinese subjects.

Sutetinib is an irreversible inhibitor of epidermal growth factor receptor (EGFR) and showed favorable efficacy and safety in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) harbouring nondrug-resistant rare EGFR mutations. To evaluate the potential food effect, eighteen healthy Chinese subjects were enrolled in a single-centre, randomized, open-label, two-sequence, two-period crossover study. Sutetinib was administered as a single oral 100 mg under fasting or fed conditions, and pharmacokinetic sampling was performed following each dose and analysed by a validated liquid chromatography/mass spectrometry method.

Treatment of Class II Malocclusion With Orthodontic Microimplant Anchorage.

Introduction: The objective of the study was to compare the effects of orthodontic microimplant anchorage (MIA) and conventional extraoral arch anchorage (EAA) on tooth structure and oral inflammatory response in patients with Class II Division I malocclusion.

Methods: A total of 104 patients with Class II malocclusion were enrolled and were randomly assigned to receive MIA or EAA treatments. Clinical efficacy was assessed at 6 months after treatment by measuring molar shift, convex distance, and hinge angle difference between maxillary and mandibular incisors.

Effects of N-acetyl-L-cysteine polysulfides on periodontitis in a mouse model.

Background: Polysulfides are reported to be involved in various important biological processes. N-acetyl-l-cysteine polysulfide with 2 sulfane sulfur atoms (NAC-S2) regulates diverse toll-like receptor (TLR) signaling pathways. Here, we aimed to determine the role of NAC-S2 in periodontitis and explore the potential mechanism.

Relationship between microRNA expression and inflammatory factors in patients with both type 2 diabetes mellitus and periodontal disease.

Objective: To investigate the expression of single-stranded microRNAs (miRNAs) in serum and gingival crevicular fluid of patients with type 2 diabetes mellitus (T2DM) complicated by periodontal disease and its correlation with inflammatory factors.

Methods: Twenty-six periodontitis patients without diabetes mellitus (periodontal group), 24 patients with T2DM (T2DM group), 22 patients with both T2DM and periodontal disease (comorbid group), and 25 healthy individuals without a history of periodontal disease (healthy group) were recruited respectively. Serum and gingival crevicular fluid specimens were collected to detect the expression levels of miRNAs and inflammatory factors including serum tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), and transforming growth factor-β (TGF-β), and their correlations were also investigated.

Correlation between salivary HBD-2 and LL-37 expression levels with blood glucose and periodontal status in patients with type 2 diabetes mellitus.

Objective: To examine the correlation between salivary human β defensin-2 (HBD-2) and LL-37 expression levels and blood glucose in relationship to periodontal status in patients with type 2 diabetes mellitus (T2DM).

Methods: The trial is available at: https://clinicaltrials.gov/ with ClinicalTrials.

Correlation between salivary developmental endothelial locus-1, interleukin 17 expression level and severity of periodontal disease in patients with type 2 diabetes mellitus.

Objective: To investigate the correlation of the salivary expression levels of developmental endothelial locus-1 (Del-1) and interleukin 17 (IL-17) with the severity of periodontal disease in patients with type 2 diabetes mellitus (T2DM).

Methods: Fifty-seven patients with T2DM and fifty-seven patients with T2DM complicated with chronic periodontitis (CP) admitted to our hospital from March 2020 to March 2021 were enrolled as the research objects and assigned to the T2DM group and T2DM+CP group respectively. Additionally, 57 healthy controls from the hospital physical examination center during the same period were included as the healthy controls.

LncRNA FGD5-AS1 promotes tumor growth by regulating MCL1 via sponging miR-153-3p in oral cancer.

Purpose: To investigate the function of long noncoding RNA (lncRNA) FGD5-AS1 in oral cancer (OC) and to further clarify the regulation of FGD5-AS1 on miR-153-3p/MCL1 axis.

Results: FGD5-AS1 was significantly increased in OC tissues and cells. Loss of FGD5-AS1 inhibited the proliferation, migration and invasion of OC cells.

Simultaneous determination of sutetinib and its active metabolite sutetinib N-oxide in human plasma by liquid chromatography-tandem mass spectrometry: Evaluation of plasma stability.

From the point of view of drug efficacy and safety, pharmacokinetic profiles of both In this work, a sensitive and reliable liquid chromatographic-tandem mass spectrometric method was established for simultaneous determination of sutetinib and N-oxide metabolite (SNO) in human plasma and further applied to a pharmacokinetic study. Analytes were extracted from plasma samples (100 μl) via acetonitrile-induced protein precipitation and separated on a C column using ammonium acetate with ammonium hydroxide and acetonitrile as the mobile phase. Positive electrospray ionization was carried out through multiple reaction monitoring with transitions of m/z 440.

Downregulation of miR-24-3p promotes osteogenic differentiation of human periodontal ligament stem cells by targeting SMAD family member 5.

Osteogenic differentiation is a complicated process that depends on various regulatory factors and signal pathways. In our research, the osteogenic differentiation capacity was analyzed by alizarin red staining, alkaline phosphatase activity, and protein levels of osteogenic differentiation markers including runt-related transcription factor 2, bone morphogenetic protein 2, and osteocalcin (OCN). We observed a notable decrease of miR-24-3p level in osteogenic-differentiated human periodontal ligament stem cells (hPDLSCs) by microarray analysis.
