[Measurement of temporomandibular joint space of patients with obstructive sleep apnea hypopnea syndrome].

Purpose: This research evaluated the morphological differences of temporomandibular joint (TMJ) between patients with obstructive sleep apnea hypopnea Syndrome (OSAHS) and normal population using magnetic resonance imaging (MRI).

Methods: Eighteen OSAHS patients were admitted from January 2014 to May 2016 and 18 healthy adults were chosen as control. OSAHS patients were divided into three sub-groups (n=6), i.

An experimental study on use of 7T MRI for evaluation of myocardial infarction in SD rats transfected with pcDNA 3.1(+)/VEGF121 plasmid.

This study aims to build the myocardial infarction model in SD rats transfected with pcDNA 3.1(+)/VEGF121 plasmid and study the effect of the transfection using 7T MRI. Twenty-four male SD rats were randomly divided into 2 groups, pcDNA 3.

Application of three dimensional reconstruction technique in selection of incision of thoracic surgical operation with robot.

Objective: To evaluate a new method to plan the incisions of thoracic surgical operation with robot using three-dimensional (3D) reconstruction techniques.

Methods: Three-dimensional reconstruction techniques were used to reconstruct the chest CT of patients with the software OSIRIX (APPLE®). Tumor location, size and relationship with the vein and artery were unambiguously obtained.

Deoxyribonucleic acid (DNA) methyltransferase contributes to p16 promoter CpG island methylation in lung adenocarcinoma with smoking.

In this study, the relationship between CpG island methylation and smoking and DNA methyltransferase in the occurrence and development of lung adenocarcinoma was explored by detecting p16 promoter methylation status. Protein and mRNA levels of p16 were detected by immunohistochemistry and in situ hybridization assays. p16 gene promoter and exon 1 CpG island locus Hap II sites methylation status was analyzed with the methylation-specific PCR.

Liver kinase B1 promoter CpG island methylation is related to lung cancer and smoking.

The aim of this study was to explore the association of CpG islands methylation of liver kinase B1 (LKB1) with primary lung cancer and smoking, providing a theoretical basis for the demethylating drug to treat lung cancer by detecting the LKB1 promoter CpG methylation. mRNA expression of LKB1 were detected by in situ hybridization and methylation status on Hap II locus of the promoter of LKB1 was analyzed by methylation-specific polymerase chain reaction (PCR). 7 of 80 LKB1 positive cases had methylation on CpG islands while 18 of 44 LKB1 negative cases had methylation on CpG islands.

Total ginsenosides synergize with ulinastatin against septic acute lung injury and acute respiratory distress syndrome.

Total ginsenosides synergize with ulinastatin (UTI) against septic acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). We randomly divided 80 cases of severe sepsis-induced ALI and ARDS into a UTI group and a ginsenosides (GS)+UTI group. Continuous electrocardiac monitoring of pulse, respiratory rate, blood pressure, and heart rate; invasive hemodynamic monitoring; ventilator-assisted breathing and circulation support; and anti-infection as well as UTI treatment were given in the UTI group with GS treatment added for 7 consecutive days in the GS+UTI group.

Is dabigatran efficacy enough to prevent stroke in atrial fibrillation patient with high CHADS2 score during peri-procedural catheter radiofrequency ablation? A case report with literature review.

Atrial fibrillation (AF) is a major cause of thromboembolic (TE) events including stroke and transient ischemic attacks, catheter radiofrequency ablation (CA) has been demonstrated to effectively eliminate AF in majority of patients. During the peri-procedural CA of AF, dabigatran, a reversible direct thrombin inhibitor, has been proved as safe and efficacy as warfarin in the prevention of thromboembolic complication. However, for patients with CHADS2 score ≥3, sometimes dabigatran may not be an ideal substitute of warfarin.

Effects of NF-κB and hypoxia on the biological behavior of Y79 retinoblastoma cells.

We aimed to investigate the influence of nuclear factor-κB (NF-κB) on the biological behavior of Y79 retinoblastoma cells exposed to hypoxia and its possible mechanism. The cells were administrated with hypoxia, and/or 5 μM pyrrolidine dithiocarbamate (PDTC) (a selective NF-κB inhibitor) to inhibit the NF-κB activity, expressions of NF-κB was measured by western blot, and the translocation of NF-κB was detected. To examine the proliferation of Y79 cells, MTT assay was applied.

[The value of ultrasound in diagnosis of IgG4-related sialadenitis].

Purpose: To study the ultrasonic manifestation of IgG4-related sialadenitis, and improve sonographers' understanding of this disease.

Methods: Based on the clinical serological test and histopathologic diagnosis, the features were evaluated by sonography in 25 cases of IgG4-related sialadenitis, including the shape and border of the gland, internal echo texture, presence and distribution of vascularity, duct dilatation, presence/absence of calculi and submandibular lymph nodes. The changes on ultrasonography in 14 patients with IgG4-related sialadenitis before and after steroid treatment were evaluated.

Capsular tension ring implantation after lens extraction for management of subluxated cataracts.

Purpose: To evaluate the safety and efficacy of implantation of a capsular tension ring (CTR) and posterior chamber intraocular lens (PCIOL) after lens extraction in subluxated cataracts.

Setting: Department of Ophthalmology,General Hospital of PLA, Beijing, China.

Design: Prospective case series.

[The relationship between expression of lung resistance-related protein gene or multidrug resistance-associated protein gene and prognosis in newly diagnosed acute leukemia].

Objective: To evaluate the relationship between the expression of lung resistance-related protein (lrp) gene or multidrug resistance-associated protein (mrp) gene and prognosis in untreated acute leukemia (AL) patients.

Methods: Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to examine the expression of lrp and mrp gene in 58 newly diagnosed AL patients.

Results: The positive rate of lrp and mrp gene expression in newly diagnosed acute lymphocytic leukemia (ALL) group was 15.
