The minimally invasive cardiovascular surgery developed rapidly in last decades. In order to promote the development of minimally invasive cardiovascular surgery in China, the Chinese Minimally Invasive Cardiovascular Surgery Committee (CMICS) has gradually standardized the collection and report of the data of Chinese minimally invasive cardiovascular surgery since its establishment. The total operation volume of minimally invasive cardiovascular surgery in China has achieved substantial growth with a remarkable popularization of concepts of minimally invasive medicine in 2019. The data of Chinese minimally invasive cardiovascular surgery in 2019 was reported as a paper for the first time, which may provide reference to cardiovascular surgeons and related professionals.

Objective    To evaluate the efficacy of hybrid ablation through compared with thoracoscopic epicardial ablation. Methods    In this study, 108 patients with all long-standing persistent atrial fibrillation (LSPAF) received thoracoscopic epicardial ablation (TEA) after enrollment. There were 82 males and 26 females at age of 56.5±9.4 years. After blanking-period, patients off antiarrhythmic therapy with sinus rhythm were divided into a hybrid ablation (HA) group (50 patients) and a TEA group (58 patients). Only patients in the HA group received catheter ablation after randomization subsequently. In at least two-year observation period, cardiovascular risk factors were observed in all groups’ patients. Results    The mean follow-up duration was 17.3-41.8 (26.9±6.1) months and there was no significant difference between two groups [8.2-40.6 (27.5±5.7) months in the HA group and 17.3-41.8 (26.4±6.7) months in the TEA group]. The off antiarrhythmic agents (AADs) sinus rhythm rate was significantly higher in the HA group than that in the TEA group at the time of postoperative 6, 12, 24 and 36 months ［96.0%, 90.0%, 83.7%, 83.7% versus 79.3%, 75.9%, 67.3%, 63.1%, HR=0.415 (95%CI 0.206-0.923)]. Conclusion    We can conclude that the efficacy of two-staged hybrid ablation for LSPAF is superior to thoracoscopic epicardial ablation alone. Patients can obtain benefit from a supplemental radiofrequency catheter ablation after blanking-period of surgical ablation, instead of those without a supplemental ablation.

Coronavirus disease 2019(COVID-19),which is caused by SARS-CoV-2,varies with regard to symptoms and mortality rates among populations.Humoral immunity plays critical roles in SARS-CoV-2 infection and recovery from COVID-19.However,differences in immune responses and clinical features among COVID-19 patients remain largely unknown.Here,we report a database for COVID-19-specific IgG/IgM immune responses and clinical parameters(named COVID-ONE-hi).COVID-ONE-hi is based on the data that contain the IgG/IgM responses to 24 full-length/truncated proteins corresponding to 20 of 28 known SARS-CoV-2 proteins and 199 spike protein peptides against 2360 serum samples collected from 783 COVID-19 patients.In addition,96 clinical parameters for the 2360 serum samples and basic information for the 783 patients are integrated into the database.Furthermore,COVID-ONE-hi provides a dashboard for defining samples and a one-click analysis pipeline for a single group or paired groups.A set of samples of interest is easily defined by adjusting the scale bars of a variety of parameters.After the"START"button is clicked,one can readily obtain a comprehensive analysis report for further interpretation.COVID-ONE-hi is freely available at www.COVID-ONE.cn.

Objective To explore the effectiveness and feasibility of internet-based structured group cognitive behavior therapy (I-GCBT) in patients with mild depressive disorder.Methods In this randomized controlled trial,based on a random number table which was generated from spss20.0,96 patients with mild depressive disorder were randomized to I-GCBT(n=64) and face-to-face group cognitive behavior therapy(GCBT,n=32).I-GCBT and GCBT patients were assessed by HAMD17,HAMA,Global Assessment of Functioning Scale,GAF and 16 Items Quick Inventory of Depressive Symptomatology-Self Report,QIDS-SR16 at baseline,4th week,8th week and 12th week.The differences between I-GCBT and GCBT were analyzed by repetitive measure analysis of variance and chi-square test.Results (1)There was no significant difference between I-GCBT and GCBT on demographics,duration of past depression history,baseline of HAMD17,GAF and QIDS-SR16,but a significantly higher HAMA seen in GCBT (t=-2.08,P=0.04).(2) The interaction of times and groups was significant in GAF (F=4.09,P＜0.01) but not in HAMD17,HAMA and QIDS-SR16 (F=0.69,P＞0.05;F=0.95,P＞0.05;F=0.64,P＞0.05).In all measurement scales,Time main effects were significant (HAMD17∶ F=32.81,P＜0.01;HAMA∶ F=20.86,P＜0.01;GAF∶ F=105.98,P＜0.01;QIDS-SR16∶ F=25.27,P＜0.01).The symptoms remission rate of the overall patients was 62％ (43/69) after 12 weeks treatment,lower in I-GCBT (57％,25/44) and higher in GCBT (72％,18/25).There was no significant difference between two groups (x2=1.57,P=0.21).(3) The overall dropout rate was 26％ during the 12-weeks treatment specifically 29％(15/51) in I-GCBT and 20％(6/30) in GCBT without significant difference in-between (x2=0.87,P=0.35).97％(58/60) patients rated the treatment as acceptable (I-GCBT∶ 97％(35/36),GCBT∶ 96％ (23/24)),and the difference of acceptability between two groups was not significant (x2=0.09,P=0.78).Conclusion The effectiveness and feasibility of I-GCBT are comparable to GCBT for mild depressive disorder.And the treatment adherence of I-GCBT seems good.

Objective To evaluate the additional efficacy of local anesthetic injection (LAI) as a part of multimodal anal?gesia in patients undergoing total knee arthroplasty (TKA) with respect to pain, narcotic use, knee function and complications. Methods A multicenter randomized, controlled, double blind study was performed. A total of 101 patients undergoing unilateral TKA in two centers were randomly divided into injection group and control group. Injection group (50 cases) received local anes?thetic injection of ropivacaine (200 mg), fentanyl (1μg) and epinephrine (1∶1 000, 0.25 mg) in operation and control group (51 cas?es) did not. All patients received standardized general anesthesia and postoperative intravenous patient controlled analgesia (PCA). Preoperative baseline data, surgery?related conditions, postoperative pain (on a 0 to 10 scale), knee function, time of open?ing PCA, narcotic dosage in PCA and complications were compared respectively. Results The time of opening PCA in injection group (4-10 h, M=8 h) was longer than that in control group (2-5 h, M=4 h) (P<0.05). The 12 h, 24 h and total narcotic use of PCA in injection group (8.62±3.601 ml, 21.22±9.220 ml, 38.52±7.764 ml) was less than that in control group (18.43±9.671 ml, 35.30± 11.414 ml, 55.52±12.405 ml) (P<0.05). At post anesthesia care unit the mean VAS in injection group (2.40±1.927) was lower than that in control group (3.06 ± 2.073) (P<0.05). There was no difference in mean VAS at other time points, knee function, length of stay between two groups (P>0.05). Conclusion LIA in TKA can relieve pain early after TKA, prolong the time of opening PCA and reduce narcotic use compared with patients without it. It is simple and safe to use.

Objective To observe efifcacy and safety of catheter ablation for atrial ifbrillation (AF) occurring after surgical valve replacement in patients with rheumatic heart disease (RHD). Methods A total of 23 RHD patients with atrial ifbrillation after surgical valve replacement were enrolled in this study from 2008 to 2013. The clinical characteristics, ablation strategies and successful rate were investigated. Results All the cases included 8 males and 15 females (age, 51.0 ± 9.2 years). Valves replaced were isolated mitral valves (13/23, 56.5%) and multiple valves (10/23, 43.5%). Postoperative AF after cardiac surgery was paroxysmal in 14 patients (60.9%) and nonparoxysmal in 9 cases. Nine patients (39.1%) was in sinus rhythm before cardiac surgery, 4 in paroxysmal AF and 10 in non-paroxysmal AF. The mean interval between the catheter ablation AF and the surgical intervention was (6.9±5.8) years. The postoperative AF duration was (3.1±3.2) years, left and right atrial diameters were (44.1±5.9) mm and (48.1±9.0) mm respectively, left ventricular ejection fraction was 64.0%±8.3%, the mean ablation procedure duration was (156.8±46.6) min, and lfuoroscopy exposure averaged (27.3±11.2) min. Standard pulmonary vein isolation was performed in all cases by using ipsilateral circumferential ablation technique. Additional ablation, including complex fractionated atrial electrograms, mitral and tricuspid isthmus, and left atrial roof, was applied in most of the cases. After a mean follow-up of (29.7±21.2) months (median, 24 months), 60.9%of the patients remained free of AF, 1 died, and 2 lost to follow-up. Conclusions Catheter ablation for AF is effective and safe in patients with RHD after surgical valve replacement. Stepwise ablation strategy may be better for these patients.
