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 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 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 To investigate the cardiac protection of Hsp27 against endotoxic cardiac depression mediated by activation of PI3K/Akt pathway and the suppression of NFκB-mediated inflammatory response in mice. Method (1) Transgenic mice with cardiac specific overexpression of Hsp27 (Hsp27 Tg) and wild littermate controls (WT) were given 10 mg/kg LPS injected intraperitoneally to induce endotoxemia, (2) The cardiac function measurement in mice was performed by using echocardiography 6 hours after LPS treatment (n = 6), (3) The activity of PBK/Akt pathway was evaluated by Western blot for [hosphor-Akt (p-Akt) and phosphor-Gsk-3β (p-Gsk-3β) one hour after LPS administration ( n = 4)], (4) Activity of inflammatory response was evaluated by protein degradation of IκBα (n = 4), (5) The apoptosis of myocardial cells was determined by TUNEL assay on the paraffin section of cardiac tissue 24 hours after LPS exposure (n = 4). Results (1) Hsp27 attenuated cardiac dysfunction significantly following LPS treatment. Compared with the primary value, LPS induced the depression of cardiac function both in WT rats and Hsp27Tg rats. However, the cardiac dysfunction was attenuated significantly in Hsp27Tg rats compared with that in WT rats ( P < 0.01 or 0.05) . (2) Hsp27 attenuated IκBα degradation after LPS administration. Compared with the primary value, LPS led to LκBα degradation by (72.92 + 9.20) % in WT rats and by (41.43 + 24.10) % in Hsp27Tg rats. The overexpression of Hsp27 lessened the IκBα degradation significantly (P < 0.05). The similar results were obtained in rat myocardial cell culture of experiments. (3) Hsp27 enhanced the activation of PI3K/Akt signaling following LPS exposure. One hour after LPS administration, the relative levels of p-Akt and p-GSK-30 were (3.11 + 0.83) and (3.19 + 1.04), respectively in WT rats, and (5.13 + 0.73) and (5.71 + 1.20) in Hsp27Tg rats, respectively. Compared with WT rats, the levels of p-Akt and p-GSK-3β were significantly higher in Hsp27Tg rats (P < 0.05). (4) The Hsp27 lessened LPS-induced the apopto-sis of myocardial cells. Twenty-four hours after LPS treatment, the percentages of myocardial cell apoptosis were (6.46+ 1.74)% in WT rats and (2.88 + 0.91)% in Hsp27Tg rats. Compared with WT rats, LPS-induced apoptosis in myocardial cells was significantly decreased in Hsp27Tg rats (P < 0.01). Conclusions The overexpression ofHsp27 attenuates cardiac dysfunction significantly during endotoxemia, and the mechanisms may be attributed to the activation of PDK/Akt signaling pathway.

Objective To study the long-term efficacy of splenectomy for patients with advanced shistosomiasis japonica.Methods Levels of WBC,RBC,PLT,EOS,ALT,ALP,GGT,A,TB,HA,LN,Ⅳ-C,PCⅢ,IGG,IGA,C3,C4,CD3,CD4,CD8,CD19 in periphetral venous blood were determined in 239 patients with advanced shistosomiasis.Meanwhile,the liver,gallbladder and spleen were examined with ultrasonography.Results The levels of WBC,PLT,EOS,ALT,ALP,IGG,IGA,LN,Ⅳ-C,CD19 increased in splenectomy group,the levels of A,TB,CD3,CD4,C3,C4 decreased in splenectomy group,while RBC,HA,PCⅢ,CD8 were not changed.Conclusion Splenectomy is a danger to hepatic function.Humoral immunity increases while cellular immunity decreases in splenectomy group.Splenectomy may aggravate the hepatic fibrosis in patients with advanced shistosomiasis.

A total of 55 cases of advanced schistosomiasis patients combined with Ⅲ-grade hepatic fibrosis and ascites were randomized into a splenectomy group and non-splenectomy group. The peripheral vein blood phlebotomized from these patients were detected for leucocytes, hematids, thrombocytes, acidophils, glutamic-pyruvic transaminase,alkaline phosphatase,albumin, total bilirubin,three-type precollagen, fore-type collagen, hyaluronic acid, IgG, IgA, C_3, C_4 and the sub-group of lymphocytes such as CD3、CD4、 CD8 、CD56 + 16. There were no significant difference on hepatic function and the level of hepatic fibrosis between the groups above metioned. It could be found that leucocytes, thrombocytes, IgG, IgA, CD56 + 16 increased while CD3, CD4, and albumin decreased in the splenectomy group. In conclusion, leucocytes and thrombocytes increase after splenectomy, cytoimmunity declines and humoral immunity enhances.

Objective Stanford type A acute aortic dissection is a life-threatening medical condition with high rates of morbidity and mortality that requires surgical repair, on an emergency basis. The extent of aortic arch repair that should be carried out during emergency surgery of this type is controversial. This study was conducted to report clinical experience on aortic arch repair and determine surgical indication, optimal operative procedures and strategy for Stanford type A acute aortic dissection. Methods 210 consecutive patients with acute Stanford A aortic dissection who underwent aortic arch replacement combined with implantation of stented elephant trunk into the descending aorta between August 2005 and August 2010. Surgical procedures included hemi-aortic arch replacement in 92 patients, subtotal aortic arch replacement in 50 patients and total aortic arch replacement in 68 patients. All operations were performed with the aid of deep hypothermic circulatory arrest and selective antegrade cerebral perfusion (SACP). Enhanced computed tomography scanning was performed to evaluate the postoperative outcomes, particularly the fate of the false lumen remaining in the descending thoracic aorta by aortic arch replacement combined with implantation of stented elephant trunk during follow up. Results Average cardiopulmonary bypass time was (146 ±52) min. The average cross clamp time was(93 ±25)min and average selective cerebral perfusion and circulatory arrest time was(35 ±14)min. The overall in-hospital mortality was 4. 8% (10/210) and morbidity was 8. 6% ( 18/210). Postoperative complications included acute renal failure, stroke, mediastinitis and respiratory insufficiency. During the follow-up period [mean (27 ± 18) months, ranged 2 to 60 months], 1 patient underwent reoperation due to the descending thoracic and abdominal aortic aneurysm. There was no late death. Follow-up enhanced CT scanning showed about 74% false lumens obliterated at the level of the distal border of the stent graft post operation. Conclusion Open aortic arch replacement is an effective approach and provides acceptable outcomes for type A acute aortic dissection. Optimal treatment strategy is the key factor to success in emergency surgical intervention.

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.
