LncRNA PVT1 induces chondrocyte apoptosis through upregulation of TNF-α in synoviocytes by sponging miR-211-3p.

Temporomandibular joint osteoarthritis (TMJ OA) is an important subtype of temporomandibular disorders (TMD). Articular cartilage destruction is considered a common pathological feature of TMJ OA, which is reported to be mainly induced by chondrocyte apoptosis. Synovial sterile inflammation is an initial factor of TMJ OA-associated articular cartilage destruction.

[3D printing navigation template-guided percutaneous radiofrequency thermocoagulation for V2 trigeminal neuralgia treatment].

Objective: This paper aimed to evaluate the effectiveness of the 3D printing puncture navigation template-guided percutaneous radiofrequency thermocoagulation for V2 trigeminal neuralgia treatment.

Methods: A total of 52 patients with V2 trigeminal neuralgia were treated with radiofrequency thermocoagulation. A total of 32 patients were treated under the guidance of the 3D printing puncture navigation template (guide plate group), while 20 patients underwent puncture via pterygopalatine fossa routinely (routine treatment group).

Acupuncture therapy in the management of the clinical outcomes for temporomandibular disorders: A PRISMA-compliant meta-analysis.

Purpose: The purpose of this study was to evaluate conventional acupuncture therapy in the management of clinical outcomes for temporomandibular disorders (TMD) in adults.

Methods: The electronic databases PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Clinical Trails.gov were searched for reports published until March 31, 2016.

MTHFR C677T gene polymorphism and head and neck cancer risk: a meta-analysis based on 23 publications.

Objective: Conflicting results on the association between MTHFR polymorphism and head and neck cancer (HNC) risk were reported. We therefore performed a meta-analysis to derive a more precise relationship between MTHFR C677T polymorphism and HNC risk.

Methods: Three online databases of PubMed, Embase, and CNKI were researched on the associations between MTHFR C677T polymorphism and HNC risk.

Association between BMP4 rs17563 polymorphism and NSCL/P risk: a meta-analysis.

Objective: To investigate the association between bone morphogenetic protein 4 (BMP4) rs17563 polymorphism and nonsyndromic cleft lip with or without palate (NSCL/P) risk.

Methods: Four online databases were researched and the related publications were collected. Odds ratio (OR) with 95% confidence interval (CI) was applied to assess the relationship; publication bias, metaregression, and sensitivity analysis were conducted to guarantee the strength of results.

Ameloblastic fibrosarcoma of the mandible: A case report and mini review.

Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic neoplasm of the jaw. AFS is characteristically composed of a benign odontogenic epithelium and a malignant mesenchymal component. The posterior region of the mandible is the predominantly occupied site.

A retrospective study of temporomandibular joint ankylosis secondary to surgical treatment of mandibular condylar fractures.

We investigated the incidence of ankylosis of the temporomandibular joint (TMJ) after open operations for fractures of the mandibular condyle, and analysed possible risk factors in a total of 385 patients with 492 condylar fractures who had been operated on in our department from 2001 to 2010. Sixteen patients developed postoperative ankylosis of the TMJ with 26 joints (5%) affected during a follow-up of 6 months-10 years. Of the 492 condylar fractures, the most common ones that were associated with postoperative ankylosis were those of the condylar head (20/248), followed by the condylar neck (6/193).

[Electrosonographic analysis of sounds emanating from temporomandibular joint without symptom].

Objective: To study the characteristic of joint sounds from temporomandibular joint (TMJ) without symptom during mandible movement.

Methods: Joint sounds of 42 asymptomatic TMJ were recorded and analyzed with K6-I system during mandible movement, the waveform, frequency range, peak frequency and amplitude of joint sounds electrosonogram were studied.

Results: Joint sounds were recorded in 25 joints of the 42 joints, 4 kinds of joint sounds were found according to the waveform, frequency range, peak frequency and amplitude of the electrosonography.

[Evaluation of temporomandibular joint function after condylectomy for condylar hyperplasia].

Objective: To investigate the temporomandibular joint (TMJ) function of the condylar hyperplasia patients after condylectomy.

Methods: Twelve patients with condylar hyperplasia were included in this study. Before and after condylectomy, they were examined and the Fricton' s Craniomandibular Index (CMI) was calculated to assess the functional disorder of TMJ.

[Clinical application of electrosonography in diagnosis of anterior disc displacement with reduction].

Objective: To investigate the electrosonography character of sounds emanating from anterior disc displacement with reduction of TMJ and the value of it in clinical diagnosis.

Methods: The sounds from healthy TMJ, anterior disc displacement with or without reduction of TMJ, and osteoarthritis of TMJ were recorded and analyzed by K6-I system, then the data was used for diagnosis of anterior disc displacement with reduction in clinic.

Results: A special kind of waveform was found in the electrosonography of sounds from anterior disc displacement with reduction repeatedly, and seldom or not in sounds from healthy joints, anterior disc displacement without reduction or osteoarthritis of TMJ.
