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 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 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 The aim of the study was to compare the mid-and long-term results between mitral valve repair and mitral valve replacement in mitral regurgitation due to infective endocarditis.Methods From January 2005 to December 2014, 225 patients with mitral regurgitation due to infective endocarditis underwent surgical treatment at our institution.159 patients(70.7%) were male, and the mean age was(42±15) years(13-76 years).Among them, mitral valve repair was performed in 89 patients(repair group) and mitral valve replacement in 136 patients(replacement group).Preoperative clinical profiles, perioperative details and follow-up data were reviewed retrospectively.Results There was no operative death in both groups.Compared to replacement group, patients undergoing mitral valve repair suffered significantly less embolism events(9.0% vs.22.8%, P<0.05) and central nerve complications(6.7% vs.17.6%, P<0.05).Patients with mitral valve vegetation were significantly less in repair group as well(59.6% vs.89.0%, P<0.05).The mean cardiopulmonary bypass time[(87±30) min vs.(86±33) min, P>0.05] and aorta clamp time[(52±21) min vs.(51±23) min, P>0.05]were similar between repair group and replacement group.Intensive care stay was significantly shorter in repair group[(1.4±0.7)days vs.(1.9±1.3)days, P<0.05] and hospital stay was shorter in repair group as well[(8.3±4.5)days vs.(9.5±5.3)days, P=0.09].Perioperative cerebral hemorrhage was observed in no patient in repair group and 2 patients(1.5%) in replacement.There was no in-hospital death in repair group.2 in-hospital(1.5%) deaths occurred in replacement group and the causes of death were cerebral hemorrhage and low cardiac output syndrome.The mean follow-up time was(40±35) months(3-134 months), and follow-up was complete in 85% patients.10 years over follow-up, freedom from heart related adverse events was 88% in repair group and 86% in replacement group(P>0.05).Conclusion Mitral valve repair was safe and feasible in mitral regurgitation due to infective endocarditis, with good mid-and long-term outcomes.Thorough excision of infective tissue and vegetation was necessary to perform mitral valve repair.Yet mitral valve replacement was a viable option in patients for whom repair was infeasible due to severe damage of valve.

BACKGROUND:Foreign studies have found that the magnesium alloy stent is safe and effective, but there are few studies on the degradation performance of magnesium alloy stents in China.OBJECTIVE:To investigate the degradation of degradable AZ31 magnesium alloy stent in the rabbit abdominal aorta and the effect of degradation process on vascularization.METHODS:Twenty-eight rabbits were enrolled, and the degradable AZ31 magnesium alloy stent was implanted into the rabbit abdominal aorta. Postoperative abdominal aortic X-ray examination and histological observation were done at 30, 60, 90, 120 days after implantation.RESULTS AND CONCLUSION:(1) X-ray examination: 30 days after implantation, the stent expanded completely with structural integrity; 60 days after implantation, the stent deformation, partial stent fracture, and lose of support were found; 90 days after implantation, only a small amount of support rod residues were found, and the majority of the stent was degraded; and 120 days after implantation, there was no support rod residual, and the stent was degraded completely. (2) Histological observation: 60 days after implantation, the number of residual support rods was less than that 30 days after implantation (P< 0.05), the number value at 90 days after implantation was lower than that at 30 and 60 days after implantation (P< 0.05), and the number value at 120 days after implantation was lower than that at 30, 60, 90 days after implantation (P < 0.05), indicating that the number of residual support rods was negatively correlated with post-implantation days. The time for complete stent degradation was 124.8 days. The intimal area at 90 days after implantation was higher than that at 30, 60, 120 days after implantation (P < 0.05), while the lumen area was smaler than that at 30, 60, 120 days after implantation (P < 0.05). There was no significant difference in the intimal area and lumen area at latter three time points after implantation. To conclude, the degradation of the degradable AZ31 magnesium alloy stent in the rabbit abdominal aorta can be completed within 124.8 days, and at 90 days after the stent is implanted, vascular intimal hyperplasia and lumen stenosis are most serious, and then gradualy reduced.

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.

AIM: To investigate the expression of vitamin D3 up-regulated protein 1 (VDUP1) in peripheral eosinophils of asthma patients and its relation with eosinophil activation.METHODS: 10 normal volunteers and 31 mild to moderate asthma patients were selected. Symptom severity, pulmonary function index, induced sputum eosinophil counts were recorded. Then, gene and protein expressions of VDUP1 and ?-actin were evaluated by RT-PCR and Western blotting, respectively. In addition, eosinophils were incubated with IL-5, both VDUP1 and ?-actin were amplified by RT-PCR. The eosinophil cationic protein (ECP) of supernatant and serum were also detected by ELISA assay. RESULTS: There was a significant decrease in expression of VDUP1 in asthma attack patients without treatment compared with normal volunteers and patients in remission. In contrast, no significant difference between the patients in remission and normal volunteers was observed. In patients with asthma attacks, a negative relationship between expression intensity of VDUP1 and EOS% in induced sputum and serum ECP concentration was also observed. The expression of VDUP1 in eosinophils was decreased by IL-5 stimulation, simultaneously, the ECP in supernatant was increased. CONCLUSION: The expression of VDUP1 in eosinophils decreases in asthma patients, and is negatively associated with serum ECP and induced sputum EOS%. EOS activation by IL-5 may be related to VDUP1 pathway.
