HSP90AA1 promotes the inflammation in human gingival fibroblasts induced by Porphyromonas gingivalis lipopolysaccharide via regulating of autophagy.

Background: Peri-implantitis of tooth seriously affects the life quality of patients. This study aimed to investigate the role of HSP90AA1 in the inflammatory of human gingival fibroblasts (HGFs) induced by porphyromonas gingivalis lipopolysaccharide (Pg-LPS), and to provide a potential therapeutic target for clinical treatment of peri-implantitis.

Methods: Pg-LPS (0.

Primary results of chest wall reconstruction with polydioxanone mesh on animals.

Background: With the development of surgical techniques and biomedical material, increasing synthetic materials are applied to the chest wall reconstruction, such as autologous rib, muscle flap, bovine pericardium and sheet metal.

Aim: To detect the safety and efficiency of synthetic material Polydioxanone (PDO) in chest wall reconstruction.

Materials And Methods: Healthy adult mongrel dogs operated with PDO, and then some clinical data were collected.

[Clinical analysis of two-phase treatment of 35 cases with Angle Class II division 1 malocclusion].

Purpose: To evaluate the clinical value of the two-phase treatment of Angle Class II division 1 malocclusion.

Methods: Thirty five cases with Class II division 1 malocclusion were treated with two-phase treatment(Twin-block functional appliance and fixed appliance).Lateral cephalograms were taken before and after treatment for each patient.

Results of radiofrequency ablation for permanent atrial fibrillation in patients undergoing mitral valve surgery.

Objectives: The study aim was to evaluate the safety and feasibility of radiofrequency ablation for the surgical treatment of permanent atrial fibrillation in patients with degenerative mitral valve disease.

Design: From August 2000 to August 2003, 40 consecutive patients (mean age 69.0 +/- 9.

[Effect of the valved stent on closure of patent ductus arteriosus in a miniswine model].

Objective: To evaluate the feasibility of a valved stent on closure patent ductus arteriosus in a Chinese miniswine model.

Methods: Self-expandable nitinol stents were made of Ni-Ti shape memory alloy (9 mm in diameter). Bovine pericardium was shaped and sutured onto the stents.

[Coronary flow obstruction in percutaneous aortic valve replacement using self-expandable valved stent: an in vitro study].

Objective: To study the effects of self-expandable and orthotopically implanted percutaneous aortic valved stent on coronary artery flow in vitro.

Methods: Self-expandable valved stent was developed with nitinol stent and bovine pericardium. The ascending aorta of Chinese mini swine hearts was cut proximal to the brachiocephalic trunk.

[Combined use of transmyocardial stents with gene therapy in the treatment of acute myocardial infarction].

Objectives: To determine the efficacy of combined use of transmyocardial stent with gene therapy to treat acute myocardial infarction in porcine model.

Methods: 24 Chinese mini swines have been divided into 4 groups randomly: group myocardial infarction (group MI n(1) = 6), group transmyocardial stent (group ST n(2) = 6), group vascular endothelial growth factor (group VEGF n(3) = 6), group transmyocardial stent and VEGF (group ST + VEGF n(4) = 6). In group MI, acute myocardial infarction animal model has been established by the ligation of the left descending coronary artery.
