BackgroundWhether the peeling of the inner limiting membrane (ILMP) increase the closure rate of idiopathic macular hole is still in controversy.Some ophthalmologist recommend vitrectomy combined with inner limiting membrane peeling for the treatment of idiopathic macular hole.However,the removal of ILMP is difficult because of its similar appearance to adjacent tissues.Objective This study was to investigate the efficacy of triamcinolone acetonide(TA) and indocyanine green(ICG) double staining-assisted vitrectomy combined with ILM peeling during the surgery.Methods A consecutive case- observational study was designed.The standardized vitrectomy was performed in 25 eye of 23 cases with IMH.During the vitrectomy,TA and ICG were injected into posterior pole vitreous to visualize and assist the ILM peeling.The dying effectiveness was observed,and the closure rate of macular hole,visual acuity,intraocular pressure and complications were evaluated after surgery.Written informed consent was obtained from each patient prior to operation.Results Posterior vitreous cortex and ILM were visible and the residual vitreous and cortex were removed clearly after dying of TA and ICG in all the 25 eyes.During the following-up duration of 3-8 months,the completely anatomical reattachment of the macular area was in 22 eyes ( 88.0％ ) and partially reattachment in 3 eyes( 12.0％ ).The best corrected vision was 0.07-0.60 in all of the operated eyes 2 months after surgery.Conclusions TA and ICG- assisted vitrectomy combined with ILM peeling appears to be a safe and effective method for IMH repair.

Objective To analyze the clinical efficacy and technical key points of genioplasty for the deformities of the chin.Methods 153 patients with chin deformities were treated with the genioplasty,and the chin was moved in any direction,including sagittally,vertically and transversely;the key points of this procedure were summarized.Results There was no severe complication such as infection or nonunion observed.15 patients had ecchymosis and faded in 2 weeks;33 patients had hypaesthesia and recovered in 12 weeks.With the 12-24 months follow-up,all the patients healed well with satisfactory aesthetic results.Conclusions The genioplasty is a reliable and efficient method for the deformities of the chin,and it can significantly improve the appearance of the chin.

Objective To compare the efficacy between autologous fat and hyaluronic acid in filling nasolabial grooves.Methods Sixty patients who wanted improvement of nasolabial grooves were involved in the study.They were randomly and equally classified into two groups:autologous fat injection group and hyaluronic acid injection group.Photographs were taken before,half a year,and one year after injection.The nasolabial grooves were also graded before,half a year,and one year after injection.The grade improvement was obtained after postoperative grade minus preoperative grade.If the grade improvement was more than 1 grade,the treatment was regarded as effective to evaluate the outcome between the two methods.Results The results of the two groups were tested by SPSS 13.0 software.The effects of the two methods were not significantly different after half a year of filling (P＞0.05).The difference was significant one year after filling (P＜0.05).In autologous fat injection,the patients had a long and magnificant swelling and redness around the nasolabial grooves;on the contrary,the patients who underwent hyaluronic acid had slight and short-time local reaction like swelling and redness.No other serious complications were found in both the groups.Conclusions The effects of the autologous fat and the hyaluronic acid are equal after half a year of filling.The autologous fat has a longer effect in one year.Both methods are safe and effective.Surgeons can select the method accordingly.

Objective　To compare the clinical efficiency of intracardiac procedures on traditional cardioplegic arrested-heart and on-pu mp beating-heart for congenital heart disease (CHD) with severe pulmonary hyper tension. Methods　Among all 153 cases, 95 cases underwent operat ions on cardioplegic arrested-heart, while 58 on-pump beating-heart. In arres ted-heart group, 79 cases with ventricular septal defect (VSD), 13 with atria l septal defect (ASD) and 3 with patent ductus arteriosus (PDA) were examined whi le in beating-heart group, 43 cases with VSD, 10 with ASD, and 5 with PDA were examined. Results　There were 12 cases of operative death (12.6%) and 8 of tracheotomy (8.4%) in heart arrested group. No operative death and tracheotomy in beating-heart group. 141 patients were followed up for 3 months to 10 year s with good recovery. There were 2 cases of right heart function failure six yea rs later in arrested-heart group.

BACKGROUNDThe optimal endpoint for catheter ablation of persistent atrial fibrillation (AF) remains ambiguous. This study investigated the impact of AF termination as a procedural endpoint and the termination mode on long-term clinical outcome.

METHODSTwo hundred and ninety-three patients who underwent stepwise ablation for persistent AF were categorized into the AF termination by ablation group and into the electrical cardioversion (CV) group. Subgroups were also analyzed based on different termination modes. Follow-up assessment included early recurrence and sinus rhythm (SR) maintenance.

RESULTSDuring initial ablation, 33 patients (11.3%) were directly converted to SR, 166 patients (56.7%) were converted to atrial tachycardia (AT) that subsequently restored SR with further ablation in 98 patients (33.4%), and a total of 162 patients (55.3%) underwent cardioversion due to persistent atrial arrhythmias. Comparison between termination by ablation and termination by cardioversion in patients exhibiting AF or AT revealed that no significant difference was observed in early recurrence (38.2% vs. 43.8%, P = 0.328) and SR maintenance (67.2% vs. 59.8%, P = 0.198) during the (23 ± 7) months follow-up. Even after repeat ablation, the SR maintenance continued to exhibit no statistical difference in above two groups (72.5% vs. 70.4%, P = 0.686). Further analysis of subgroups, however, demonstrated that patients with AF terminated directly to SR experienced better clinical outcomes than other subgroups (P < 0.05). Furthermore, atrial arrhythmias present during ablation have been implicated in prediction of recurrence mode: AF or AT (P < 0.05).

CONCLUSIONSTermination as a procedural endpoint is not associated with favorable long-term SR maintenance in persistent AF. AF methods that convert arrhythmia directly to SR have, however, been linked with improved clinical outcomes, although conversions to AT may not be correlated. Atrial arrhythmias observed during the ablation may be used to predict the recurrence mode.
