Objective Analysis the clinical data of high-EuroSCORE 114 patients due to ronary surgery to elucidatethe surgical advantages between on-pump and off-pump CABG.Methods From September 2008 to March 2011,114 highEuroSCORE patients due to coronary surgery were randomly divided into off-pump group 48,and on-pump gronp 66 cases.Preoperative,intra-operative and peri-operative clinical data of all the patients were collected.All patients were followed up for 1 month postoperatively.Results The baseline of the two groups had no significant difference.Application of internal mammary artery,positive inotropic drugs and IABP assistance between the two groups were similar,P ＞0.05,Compared with the offpump group,patients in on-pump gnup had longer operation time,hut more graft counts and a higher rate of revascularization [ (3.71±0.55)gnifis vs.(2.82±0.39)grafts ],P ＜ 0.05.There were no significant differences of peri-operative mortality and post-operative complications between the two groups,P ＞0.05.The patients in on-pump group had more post-operative chest drainage in the first 24 hours[ (875.0±134.2)ml vs.(589.4±102.5)ml] and blood transfusion[ (656.3±84.4)ml vs.(433.3±62.9) ml ] compared with the off-pump group,P ＜ 0.05.The data of l-month follow up denonstrated that echocardiographic data,NYHA and symptoms of angina of the two groups had no significant difference,P ＞ 0.05.Conclusion Compared with OPCAB,CCAB did not increase postoperative renal failure,neurological complications and lung injury in highrisk patients,but had more complete revascularization.The disadvantage of CCAB was postoperative bleeding,blood productsuse.

Objective To explore the effect of positive end expiratory pressure (PEEP) on arterial oxygenation and intrapulmonary shunt during one-lung ventilation (OLV) and pulmonary function during perioperation. Methods Forty patients with normal pulmonary function,ASA I - II :scheduled for pulmonary lobectomy, were divided into control group and PEEP group by random digits table with 20 cases each. Patients were induced by double-lumen tubes under intravenous anesthesia and were received 10 ml/kg tidal volume, 12 frequents/min breathing rate during the two-lung ventilation (TLV), secondary reduced to 6 ml/kg tidal volume, 16-18 frequents/min breathing rate without PEEP (control group) or with 5 cm H2O cm H2O =0.098 kPa) PEEP (PEEP group) during OLV.Hemodynamics and respiratory mechanical parameters were continuously monitored, lung function before operation and at 72 h after operation was detected. Results Compared to before OLV,arterial oxygen tension (PaO2), arterial oxygen saturation (SpO2), oxygenation index (OI) were decreased and intrapulmonary shunt ratio (Qs/Qt) was increased in control group and PEEP group at 30 min after OLV (P < 0.01 or < 0.05). However,PaO2 and SpO2 and OI were higher and Qs/Qt was lower in PEEP group than that in control group at the same time point (P<0.05). In addition, FEV1%, FVC% and FEV1/FVC were (121.8 ± 25.0% ,(117.2 ± 24.3)% , (87.6 ± 15.7)%before operation and (84.9 ± 21.6)%, (77.2 ± 18.3)% , (70.5 ± 12.5)% at 72 h after operation respectively in control group, (116.9 ±24.5)% , (112.1 ±23.6)% , (85.3 ± 13.8)% before operation and (96.3 ± 20.4)%, (88.1 ± 19.8)% , (78.4 ± 10.2)% at 72 h after operation respectively in PEEP group. Although decreased in control group and PEEP group at 72 h after operation comparing with preoperation (P< 0.01 or < 0.05 ), FEV1%, FVC% and FEV1/FVC were higher in PEEP group than those in control group at 72 h after operation (P<0.05). Conclusion Appropriate PEEP increases arterial oxygenation,reduces Qs/Qt and improves pulmonary function during OLV,reduces the risk of hypoxernia and lung injury induced by OLV during perioperation.

Objective To observe the mechanism of Siwu Decoction (Decoction of four ingredients) on blood deficiency syndrome.Methods Wistar rats were randomized into 3 groups: model group, treatment group, and normal group, 6 ones in each. Rats of the model group and the treatment group were injected 2% acetylphenylhydrazine (APH) saline subcutaneously on the first, forth and seventh day. From the forth day, the model group was treated with saline by gavage, the treatment group was treated with Siwu Decoction by gavage, and the normal group was treated with saline for 7 days in succession. Then the amount of peripheral blood cells, wet weight of liver and spleen were detected. Liver mitochondrial proteome of all rats were extracted. Proteomic technology was used to measure the regulated proteins by Siwu Decoction.Results In the model group, the rats had decreased general status significantly such as pale, enlarged liver and spleen, lowered red blood cells (RBC) and hemoglobin (HGB), increased white blood cells (WBC) and reticulocyte (RCT) (P

Objective To investigate the serum levels of fatty cytokines in hepatitis B patients with liver fibrosis.Methods Fifty six hepatitis B patients with liver fibrosis admitted in Wenzhou Central Hospital from April 2014 to March 2016 were recruited as case group and 65 healthy subjects as control group.Serum cytokines including omentin,leptin,adiponectin and visfatin were detected in both two groups and glutamyl endopeptidase (ALT),aspartate aminotransferase (AST) and hepatitis B virus DNA were detected in the case group.Liver biopsy was performed in the case group and histologic activity (HA) and histologic fibrosis (HF) stage were evaluated.Results The level of omentin in the case group was significantly higher than that in the control group [(358-119) vs.(305 ± 108) μg/L,t =2.236,P =0.037].Serum omentin,visceral fat hormone,leptin and adiponectin were not associated with liver function and HBV-DNA (P ＞0.05).There was no significant difference in adipocytokines levels between the low and high HA group (P ＞ 0.05).The level of omentin in high HF stage group was significantly higher than that in low HF stage group [(398 ± 130) vs.(292 ± 120) μg/L,t =2.648,P =0.009],while the other fatty cytokines did not show significantly differences between high and low HF groups (P ＞ 0.05).Conclusion Serum omentin level is elevated in hepatitis B patients with liver fibrosis and is associated with liver fibrosis severity.

Objective We sought to evaluate the efficacy of bipolar radiofrequency ablation of atrial fibrillation (AF) in patients undergoing cardiac surgery,and to determine independent factors affecting the recurrence.Methods From June 2007 through February 2010,81 patients with atrial fibrillation underwent a modified Cox-Maze Ⅳ procedure using a biopolar radiofrequency device( Medtronic in 32 cases,Atricure in 49 cases).There were 45 males and 36 females,aged (48.2 ± 11.0)years,including 26 cases of permanent AF,44 cases of persistent AF and 11 cases of paroxysmal AF.The mean duration time of AF was (7.56 ± 7.47 ) years.The left atrial diameter were 36 ～ 72 mm.In conjunction with cardiac surgery including:mitral valve replacement (MVR) (or add tricuspid valve plasty (TVP) in 33 cases,mitral and aortic valve replacement (DVR)( or add TVP) in 18 cases,off-pump coronary artery bypass surgery (OPCAB) in 16 cases,aortic valve replacement (AVR) in 4 cases,MVR and coronary artery bypass grafting (CABG) in 1 case,mitral valve plasty (MVP) in 1 case,and others in 8 cases.Among them,22 patients were undergoing electrophysiological mapping by high-frequency bipolar stimulation from June 2009 to February 2010.A follow-up of 12 to 44 months was completed.Recurrences were evaluated by 12-lead ECG or 24 hour Holter recording every clinic visit-1,3,6,9,and 12 months after the procedure and yearly thereafter,or if symptoms developed.Multivariate regression analysis was performed to determine independent factors affecting the recurrence.Results Hospital mortality was 1.23％.The successful ablation of AF were 100％,82.5％,and 84.8％ immediately after operation,at discharge,and at 2(6.1 ± 13.6) months after operation respectively.Multinomial regression analysis showed small left atrium ( ＜ 60 mm),and electrophysiological mapping might contribute better sinus rhythm restoration ( P ＜ 0.05 ).Conclusion Bipolar radiofrequency ablation of atrial fibrillation in patients undergoing cardiac surgery is safe and effective.Small left atrium ( ＜ 60mm) and electrophysiological mapping should be considered to improve results in selected patients.

Objective To review retrospectively the experience of surgical treatment of Ebstein anomaly in 45 adult patients.Methods Between January 2008 and December 2011,45 adult patients underwent surgery for Ebstein anomaly.There were 14 male and 31 female patients aged 18 to 61 years (mean,39 years).The main symptoms included chest tightness,shortness of breath,palpitation.25 patients had cyanosis,while 6 patients with Wolff-Parkinson-White syndrome.Preoperative echocardiography: The septal downward from 2.5 cm to 7.5 cm,average 4.2 cm; the posterior leaflet downward 3.0 cm to 8.0cm,average 5.1 cm.Tricuspid incompetence was moderate in 6 patients and severe in 29.According to Carpentier classification,5 cases of type A,30 type B,type C in 6 cases.Preoperative New York Heart Association(NYHA) functional class Ⅱin 14 cases,Ⅲ 30 cases,Ⅳ in 1 cases.Surgical procedures included modified Danielson's in 15 patients,modified Carpentier's in 23,and 7 patients underwent tricuspid valve replacement(incloud 4 secondary operations).The ratio of tricuspid valve repair was 84.4％.Autologous pericardium patch was used to reconstruct the septal and posterior leaflets in 5 cases.Intraoperative use of annuloplasty rings in 21 cases.Results There were 2 hospital deaths with a postoperative mortality of 4.4％.The main causes of death were low cardiac output and right heart failure.Operation to discharge time was (8.0 ± 3.8)days.The follow up time was 2 to 46 months.Echocardiography examination: Within the 32 patients of severe tricuspid regurgitation before tricuspid valve plasty,16 patients’ tricuspid regurgitation disappeared,13 patients with mild regurgitation,3 moderate regurgitation.Within 5 patients of moderate tricuspid regurgitation before tricuspid valve plasty,4 cases tricuspid regurgitation disappeared after operation,1 case tricuspid valve mild regurgitation.Tricuspid valve leaflets were at normal levels,the atrialized portion of the ventricular disappeared.The heart function improved to be NYHA class Ⅰ to Ⅱ in 95 ％ of the survived patients.Conclusion Operative method of Ebstein anomaly sould be selected according to the type of pathoanatomies.Tricuspid valve repair should be performed to the best of our ability.

This study was aimed to investigate the effects of high-dose strictosamide injection on cardiovascular sys-tem of anesthetized beagle dogs and to examine the inhibition of strictosamide on ion channels in vitro. Indexes such as changes of systolic blood pressure (Sys), diastolic blood pressure (Dia), mean blood pressure (MBP), heart rate (HR), PR, QRS, QT, QTcb and QTcv at different time points before and after strictosamide injection in dogs were monitored by the polygraph system. The inhibition of strictosamide at different concentrations on hERG potassium channel in CHO-hERG cells and Nav1.5 sodium channel in HEK-293-Nav1.5 cells were measured by whole-cell patch-clamp method. The results showed that compared with the blank control group, Sys, Dia, MBP and HR were obviously declined 15 min after medication in the strictosamide (60, 18 mg·kg-1) group and the vehicle-control group (containing tween-80) (P < 0.05). After medication, all indexes were recovered. Compared to the vehicle-control group, there were no significant differences at different time points in each medication groups. Compared with the blank control group and before medication, the QT interval, QTcb and QTcv were significantly prolonged 15 min af-ter medication in the strictosamide (60, 18, 6 mg·kg-1) group and the vehicle-control group (P< 0.05). When medi-cation stopped, indexes were recovered at certain level. Compared with the vehicle-control group, there were no sig-nificant differences of QT interval, QTcb and QTcv of each medication group at different time points (P> 0.05). The inhibition of strictosamide on hERG potassium channel and Nav1.5 sodium channel were weak with IC50 values of 560.8 μM and > 900 μM, respectively, which were far greater than the positive controls. It was concluded that sin-gle, high-dose intravenous injection of strictosamide may lead to a lower blood pressure, a slower heart rate and a prolongation on the QT interval in beagle dogs, which returned to basal levels when medication stopped. It was spec-ulated that the reduction of blood pressure and the slowing of heart rate were related to tween-80 contained in the vehicle control group. No significant inhibitory effects were detected on hERG potassium channel and Nav1.5 sodium channel in vitro, which suggested that other mechanisms may be involved in strictosamide-induced QT interval pro-longation in animals.

Objective Functional mitral regurgitation (FMR) refers to the systolic regurgitation of mitral valve secondary to compromised cardiac function or geometry abnormity with non-organic change of leaflets and ancillary parts of the valve.Severe aortic insufficiency (AI) with left ventricular dilation and dysfunction is clinically a complex heart disease and its postoperative complications and mortality are higher than usual valvular surgery.And such patients are often accompanied by FMR.It is generally acknowledged that FMR may improve after aortic valve replacement (AVR).This study follow up AI patients with left ventricular dilation and dysfunction and preoperative 2 + ＜ FMR ≤3 + to evaluate the outcome of FMR after AVR.Preoperative clinical data is assessed by regression analysis.Methods From January 2000 to April 2011,74 cases of patients were treated,who with severe aortic regurgitation combined with left ventricular dilation (left ventricle,LVEDD ≥ 70 mm) and dysfunction (left ventricle ejection fraction,LVEF ≤ 0.35) accompanied by 2 + ＜ FMR ≤3 +.Postoperative follow-up was performed.Calculation FMR preoperative/FMR postoperative ratio,the age,sex,weight,high blood pressure,ventricular arrhythmia,atrium fibrillation,LVEDD,LVEF,left atrium diameter(LAD),pulmonary artery pressure (PAH),mitral leaflet coaptation point and the mitral annular(CPMA).All factors for logistic multiple faotors regression analysis.Results The perioperative mortality rate was 8.1％.Average follow-up time was (14.9 ± 7.7) months and follow-up rate of 83.6％.5 patients died during follow-up.6 months after surgery,the average of FMR was 2.64 ± 1.17 (+),P ＞0.05 compared with preoperative data.LVEDD,LAD,CPMA,P ＞0.05 compared with the preoperative data.LVEF,PAH,both P ＜0.05 compared with preoperative data.3.Multiple regression analysis:FMR preoperative/FMR postoperative ratio is not correlated with age,gender,weight,LVEDD ≥75 mm,LVEF≤0.30,hypertension,ventricular arrhythmia and FMR postoperative improvement.However,PAH ≥50 mm Hg,LAD ≥50 mm,PAH ≥50 mm Hg,CPMA ≥ 15 mm,preoperative atrial fibrillation was negatively correlated with FMR postoperative improvement.Conclusion Severe AI with left ventricular dilation and dysfunction is a critical clinical heart disease and its postoperative complications and mortality were high.PAH ≥50 mm Hg,LAD ≥50 mm,PAH ≥50 mm Hg,CPMA ≥15 mm,preoperative atrial fibrillation was negatively correlated with FMR postoperative improvement.Since patients with 2 + ＜ FMR≤3 + usually do not improve or even worsen after AVR,those who have these above conditions preoperatively,should be treated on FMR during AVR.
