Objective To evaluate the clinical application of 2000 ArthroCare System in knee arthroscopic surgery. Methods 221 cases of knee problems were treated with 2000ArthroCare System. The disorders of the 221 cases diagnosed by the arthroscopy were as follows: 73 cases of osteoarthritis, 49 meniscus tear, 29 degenerative cartilage injury, 11 plica synovitis, 11 Kaschin Beck disease, 8 ACL, 5 osteochondritis dissecans, and 2 TKA brisement. The operative procedures, such as meniscectomy, meniscoplasty, fitting of cartilage and ligament, synovectomy, and release of lateral patellar retinaculum, were done with 2000ArthroCare System and arthroscopy. Results The Lysholm Knee scores were 43.92 preoperatively, 81.96 three months postoperatively, and 92.06 six months postoperatively. Conclusion Knee problems can be effectively released with 2000 ArthroCare system vaporization under arthroscopic guidance. The advantages of this procedure are very limited tissue damage, mild reaction, less blood loss, early rehabilitation, and fine functional recovery.

Objective To investigate the effect of locking plate fixation in treatment of complex tibial plateau fractures. Methods A total of 100 patients with tibial plateau fracture from June 2011 to June 2014 in our hospital as the re-search objects, all the patients were divided into group A and group B, 50 cases in each group, 50 cases were treated with locking plate fixation from June 2013 to June 2014, establishment of group A in our hospital, 50 cases were treated with normal anatomic plate internal fixation from June 2011 to June 2012 as group B, the curative effect and operation indicators, complications were observed and compared between the two groups after treatment. Results The excellent and good rate was 86% in group A, the excellent and good rate was 72% in group B, the difference was statistically significant between two groups (P<0.05). The amount of bleeding during the operation of group A was lower than that in group B, but fracture healing time of group A was shorter than group B, the incidence of postoperative complications of group A was lower than that in group B, the difference was statistically significant (P<0.05 or P<0.01). But compared the operation time between group A and group B, the difference was not significant (P>0.05). The two groups of each one case had local skin infection, after dressing and using sensitive antibiotics were cured; Two cases in group B after incision exudation, delayed healing, due to fat liquefaction or artificial bone reaction, and was cured after changed the dressing; Group B had one case of delayed healing, one case of screw loosening occurred fracture, but no impact on fracture healing. Conclusion With plate fixation in the treatment of complex tibial plateau lock, can significantly im-prove the knee joint function of patients, Less bleeding, fewer complications, fast fracture healing is worthy of promo-tion and application.

Objective To compare operation effects of PFNA and DHS in treatment of femoral intertrochanteric frac-ture. Methods A total of 73 cases of intertrochanteric fracture patients were divided into PFNA group (n=38) and DHS group (n=35) according to the different treatment methods. The function of hip joint were compared between two groups and the operation time, the amount of bleeding and the time of fracture healing were observed and recorded. Results The excellent and good rate of PFNA group and DHS group was 92.1% (35/38) and 80.0% (28/35), the difference was statistically significant between two groups (χ2=4.237, P<0.05). The operation time of group PFNA was(72.7±11.6)min, amount of bleeding during the operation was(84.6±10.7)mL, healing time of fracture was(12.1±1.3)weeks. The amount of bleeding operation time in DHS group was (112.8±10.2)min, amount of bleeding during the operation was(173.3±31.2) mL, healing time of fracture was (14.8±2.7)weeks, compared two groups, the difference was statistically significant (P<0.05 or P<0.01). There was significant difference in complications between two groups(P<0.05). Conclusion PFNA and DHS are both effective ways in treatment of senile femoral intertrochanteric. PFNA in treatment of senile in-tertrochanteric fractures with less bleeding, short operation time, less complications, especially, the therapeutic effect is superior than that of DHS internal fixation.

BACKGROUND: Oral anti-coagulants (OAC) are the intervention for the prevention of stroke, which consistently improve clinical outcomes and survival among patients with atrial fibrillation (AF). The main purpose of this study is to identify problems in OAC utilization among hospitalized patients with AF in China. METHODS: Using data from the Improving Care for Cardiovascular Disease in China-Atrial Fibrillation (CCC-AF) registry, guideline-recommended OAC use in eligible patients was assessed. RESULTS: A total of 52,530 patients with non-valvular AF were enrolled from February 2015 to December 2019, of whom 38,203 were at a high risk of stroke, 9717 were at a moderate risk, and 4610 were at a low risk. On admission, only 20.0% (6075/30,420) of patients with a diagnosed AF and a high risk of stroke were taking OAC. The use of pre-hospital OAC on admission was associated with a lower risk of new-onset ischemic stroke/transient ischemic attack among the diagnosed AF population (adjusted odds ratio: 0.54, 95% confidence interval: 0.43-0.68; P  <0.001). At discharge, the prescription rate of OAC was 45.2% (16,757/37,087) in eligible patients with high stroke risk and 60.7% (2778/4578) in eligible patients with low stroke risk. OAC utilization in patients with high stroke risk on admission or at discharge both increased largely over time (all P  <0.001). Multivariate analysis showed that OAC utilization at discharge was positively associated with in-hospital rhythm control strategies, including catheter ablation (adjusted odds ratio [OR] 11.63, 95% confidence interval [CI] 10.04-13.47; P <0.001), electronic cardioversion (adjusted OR 2.41, 95% CI 1.65-3.51; P <0.001), and anti-arrhythmic drug use (adjusted OR 1.45, 95% CI 1.38-1.53; P <0.001). CONCLUSIONS In hospitals participated in the CCC-AF project, >70% of AF patients were at a high risk of stroke. Although poor performance on guideline-recommended OAC use was found in this study, over time the CCC-AF project has made progress in stroke prevention in the Chinese AF population.Registration:ClinicalTrials.gov, NCT02309398.
