Annexin A1 involved in the regulation of inflammation and cell signaling pathways.

With the deepening of research, proteomics has developed into a science covering the study of all the structural and functional characteristics of proteins and the dynamic change rules. The essence of various biological activities is revealed from the perspectives of the biological structure, functional activity and corresponding regulatory mechanism of proteins by proteomics. Among them, phospholipid-binding protein is one of the hotspots of proteomics, especially annexin A1, which is widely present in various tissues and cells of the body.

Adenovirus-mediated transduction with Histone Deacetylase 4 ameliorates disease progression in an osteoarthritis rat model.

Background: Downregulation of histone deacetylase-4 (HDAC4) contributes to cartilage degeneration in osteoarthritis (OA) because it promotes upregulation of runt-related transcription factor-2 (Runx-2) and osteoarthritis-related genes. The effect of HDAC4 upregulation on cartilage damage in OA remains unknown.

Methods: Rat chondrocytes were infected with Ad-GFP or Ad-HDAC4-GFP for 48 h, stimulated with interleukin-1β (IL-1β, 10 ng/mL) for 24 h, and then harvested for RT-qPCR.

Cholesterol pericarditis associated with rheumatoid arthritis: A rare case report.

Background: Cholesterol pericarditis (CP) is a special type of pericarditis. It is characterized by chronic pericardial effusion with high cholesterol concentration and with or without the formation of crystals in pericardial effusion.

Methods: In this case report, we described a 74-year-old male with massive pericardial effusion.

Association of blood pressure level with nonalcoholic fatty liver disease in nonhypertensive population: Normal is not the new normal.

The functional crosstalk between nonalcoholic fatty liver disease (NAFLD) and hypertension has been reported by some literatures; however, in nonhypertensive individuals, there is no article describes the characteristic of NAFLD. In this study, we aimed to determine the strength of the association between NAFLD with normal blood pressure (BP) in nonhypertensive individuals. This cross-sectional study was conducted in the sixth Affiliated Hospital of Wenzhou Medical University, from October 2007 to December 2011.

[Preliminary clinical experience on radiofrequency catheter ablation of right-sided accessory pathway guided by Ensite-NavX navigation].

Objective: To explore the feasibility and methodology of radiofrequency catheter ablation (RFCA) guided by 3D navigation system (Ensite-NavX) for right atrioventricular accessory pathway.

Method: Thirty-three cases of right accessory pathway atrioventricular reentrant tachycardia including 16 cases in right free wall, 3 in right middle septum, 14 in right posterior septum; 23 cases of dominant accessory pathway and 10 cases of concealed were treated by RFCA guided by NavX navigation. NavX navigation modeling method or spatial localization method was exploited to locate target positioning.

[Comparison of cryoablation and radiofrequency ablation for treating atrioventricular nodal reentrant tachycardia].

Objective: To compare the efficacy and safety between cryoablation (Cryo) and radiofrequency (RF) ablation for treating patients with atrioventricular nodal reentrant tachycardia (AVNRT).

Methods: Patients with AVNRT (n = 304) were divided into Cryo group (n = 67) and RF group (n = 237). The procedure success rate, complete slow pathway block rate, atrioventricular block rate and relapse rate were compared between two groups.
