Objective To Summary the first 40 cases underwent robotic atrial septal defect (ASD) closure or atrial septal defect closure combined bicuspid valve plasty (TVP) using da Vinci S surgical System on beating heart. Methods 40 cases of atrial septal defect or combined sever tricuspid valve regurgitation were repaired using da Vinic S surgical system on beating heart from March 2009 to December 2010 in cardiovascular department of PLA general hospital. The average age was (38 ± 13) yeas old. 23 cases were female and 17 cases were male. All patients were ostium atrial septal defect with or without pulmonary hypertension. The atrial defect diameter was 1.5 -3.5 cm, and the mean diameter was(2. 8 ±1.3)cm. 9 patients had sever tricuspid valve regurgitation. Without sternotomy, the extracorporeal circulation was established through groin artery,groin vein and internal jugular vein cannulation with the guidance of transeophageal echocardiography. 3 ports of 8 mm and 1 working port of 2 cm were made in the right chest wall. After da Vinci S syetem was set up, with the assistant of bed-side surgeon, the surgeon completed the atrial septal defect closure or combined tricuspid valve plasty in the surgeon console with three dimensions visualization. During the operation, without cardioplegia administrated and aortic occlusion, the procedure was completed through right atriotomy. The pleural space was insufflated with carbon dioxide to avoid the air embolism. The direct suturing was used in 22 cases and pericardial patch were used in 18 cases. 9 patients accepted concurrent De Vega tricuspid valve plasty. The transesophageal echocardiography were used to evaluate the result of atrial defect closure or tricuspid valve repair. The operation time, robotic using time and cardiopulmonary time were compared with totally robotic atrial defect repair in arrested heart. Results All cases were accomplished successfully without complication. There was no residual shunt and air embolism. The operation time, robotic using time and cardiopulmonary time were less than the arrested group. Conclusion Robotic atrial septal defect closure or combined tricuspid valve repair on beating heart can avoid aortic ocllusion and can be utilized effectively and safely.

Objective To investigate the diagnostic value of procalcitonin(PCT)as an early indicator for sepsis.Methods Serum levels of PCT and C-creative protein(CRP)and white blood cell (WBC)count were measured in 30 patients in critical condition hospitalized at an intensive care unit(ICU) with diagnosis of systemic inflammatory response syndrome(SIRS).They were divided into two groups, sepsis and non-sepsis,based on their clinical manifestations and results of lab tests.Blood specimen was collected from each patient for measurement of PCT,CRP and WBC count on the 1~(st),3~(rd)and 7~(th)day after hospitalization and bacteriological culture for blood and sputum,and chest X-ray was performed,as well. Acute physiology,age and chronic health evaluation(APACHE Ⅱ)was made on the 1~(st),3~(rd)and 7~(th)day after hospitalization to assess their ill condition.Their prognosis were judged on the 28~(th)day of the follow-up. Results Serum level of PCT increased significantly in the sepsis group(with the highest of 10.13 ng/ml), as compared with that in the non-sepsis group.Sensitivity,specificity and predictive value of a positive test for a cut-off value of serum level of PCT at 0.5 ng/ml were 97.0%,91.7% and 82.1%,respectively, which were all better than those of serum level of CRP and WBC count.Serum level of PCT in the patients was significantly associated with their prognosis,and PCT in those died was significantly higher than that in those survived.Whereas,serum level of CRP and WBC count elevated in both groups,but the difference between the two groups did not reach a level of statistical significance.Conclusion Serum level of PCT can be used as an early indicator for judgment of sepsis for a patient with infection and reflection of severity of illness.

Objective To explore effects of heat stress response on neutrophil apoptosis and respiratory burst function. MethodsNeutrophils from each of 18 healthy volunteers were divided into 3 parts,and one part was served as control group,and the other two parts were induced by heat shock or cadmium chloride for heat stress response and named as heat shock group and cadmium chloride group.The neutrophils were incubated in culture medium.At 0,2,3,4,and 6 h following heat stress induction,the heat shock protein(HSP70) expression and the respiratory burst were detected in the neutrophils respectively by using PCR technique and flow cytometer.Level of apoptosis was observed by immuno-fluorescence and flow cytometer DNA ploid at 24 h after heat stress induction. Results In the heat shock and cadmium chloride groups,HSP70 expression at each time point and cell apoptosis at 24 h were significantly higher than those of control group(P

BACKGROUND:Though the effects of conservative or traditional open reduction and internal fixation in the treatment of thoracolumbar fractures are reliable and satisfactory for most cases, two methods also have shortages. Minimal-invasive percutaneous pedicle screw system provides a new available method. OBJECTIVE:To investigate the clinical effect of Sextant percutaneous pedicle screw system in the treatment of thoracolumbar fractures. METHODS:A total of 55 patients, who had undergone percutaneous pedicle screw fixation using Sextant system (25 patients) or traditional open internal fixation (30 patients) for single-level vertebral body compression fractures in Department of Orthopedics of Renmin Hospital of Wuhan University from February 2011 to January 2013, were enrol ed in this study. RESULTS AND CONCLUSION:Except two patients in traditional open internal fixation group were lost after discharge, al other patients were fol owed up for 8-14 months. Operative time, intraoperative blood loss, postoperative drainage amount and hospital day were better in percutaneous pedicle screw fixation group than in the traditional open internal fixation group (P<0.05). Compared with preoperation, the sagittal Cobb angle, visual analogue scale and Oswestry disability index after operation were significantly lower (P<0.05), while anterior vertebral body height ratio was significantly higher in each group (P<0.05). No significant difference was found in terms of correction loss and Oswestry disability index between two groups at 8 months after operation (P>0.05). The results show that percutaneous pedicle screw fixation using Sextant system has a satisfactory outcome in the treatment of thoracolumbar fractures. However, obeying indication strictly is very important for clinical application.

BACKGROUND: Many scholars adopt allograft interbody fusion for vertebral body resection and reconstruction, bone fusion time is better than autologous bone graft's, and its integration provides an early support and stabilizing, but the preparation of allogeneic bone graft material is easy to destroy b0ne-inducing factor in matrix, which is not conducive to bone growth. OBJECTIVE: To innovatively design and verify the ability of reconstructing rabbit cervical vertebrae with the compound of humeral cortical ring allograft (HCA) packed with red bone marrow (RBM) and autogenous cancellous bone (ACB). DESIGN, TIME AND SETTING: Randomized controlled animal experiment was performed at the laboratory of Orthopedic Department in Renmin Hospital of Wuhan University, between October 2004 and March 2006. MATERIALS: Sixty healthy adult New Zealand white rabbits, of either sex, body mass of 2.0-2.5 kg, were involved in this study. Twelve rabbits were used for HCA preparation, while the remaining 48 rabbits were randomly divided into 3 groups with sixteen rats in each group. Autologous RBM was extracted from the anterior superior lilac spine through puncture; ACB was obtained from td-cortical bone of rabbit iliac crest. Autologous RBM and ACB were compounded and filled in the self-made HCA. METHODS: Models of the fourth cervical vertebrae defect were created by surgery to simulate tumor resection in New Zealand white rabbits, which were divided into 3 groups randomly. Combined transplant group was treated with the compound of RBM+ACB+HCA; autologous bone transplant group with autogenous lilac crest; HCA transplant group with HCA. MAIN OUTCOME MEASURES: Vertebral reconstructions were evaluated by X-ray, histopathological observation and scanning electron microscope, as well as measurement of serum alkaline phosphates at different periods postoperatively. RESULTS: Eight weeks post-surgery, graft materials fused with the upper and lower cervical fusion, a large number of bone callus were observed in combined transplant group and autologous bone transplant group; HCA transplant group was present with a small amount of callus growth and poor fusion. Serum alkaline phosphatase levels were elevated in all groups, significantly higher in combined transplant group and autologous bone transplant group compared with HCA transplant group (P < 0.01 ). There were no significant differences of serum alkaline phosphatase levels between combined transplant group and autologous bone transplant group at 4 weeks or among 3 groups 8 weeks (P > 0.05). Histological analysis exhibited numerous mature bone matrix, bone trabecula and bone marrow cavity formed in combined transplant group and autologous bone transplant group. Scanning electron microscopy showed that many new bone formations in combined transplant group and autologous bone transplant group.CONCLUSION: The compound of RBM+ACB+HCA and autogenous lilac crest transplantation can efficiently reconstruct cervical vertebrae, RBM+ACB can improve the reconstruction efficiency of HCA, and could use as a matedal in cervical reconstruction.
