Objective To study the feasibility, superiority and experience of minimally invasive laparoscopic-assisted surgery of the thyroid using ultrosonic scalpel. Methods In a period from January, 2006-August, 2008, 56 patients of the department of general surgery, the hospital of Heilongjiang Province were diagnosed as thyroid node. The size of the nodes ranged from 5.0 cm×4.2 cm to 3.5 cm×2.0 cm in uhrosonography. An incision of about 1.5-2.0 cm was made 1.0 cm above the suprasternal notch and the operation was performed with ultrosonic scalpel assisted with laparoscope. Partial thyroideetomy of lateral thyroid was performed in 20 cases, subtotal thyroidectomy in 25 cases, subtotal thyroidectomy of unilateral thyroid and partial thyroidectomy of contralateral thyroid respectively in 1 case, partial thyroidectomy of bilateral thyroid in 10 cases. Results All 56 cases have undergone minimally invasive laparoscopic-assisted surgery successfully in 50-146 min and no complications occurred. Fifty five cases were confirmed to be benign lesion pathologically. Conclusion Laparoscopic-assisted surgery of the thyroid is an effective with a good cosmetic result.

Objective:To investigate the clinical efficacy of gabapentin capsules( GBP)combined with amitriptyline and tramadol in the treatment of patients with postherpetic neuralgia( PHü)and anxiety. Methods:Totally 106 PHü patients with anxiety symptoms at different degree were selected and divided into group A(n=53)and group B(n=53). Group A was given GBP,amitriptyline and tramadol,while group was given GBP only. The anxiety,depression,quality of life and pain-relieving intensity( by VAS)of the pa-tients were determined before the medication( T1 )and in the first week( T2 )and the fourth week( T3 )after the medication. Follow-up was carried out regularly according to the requirements to evaluate the clinical efficacy. Results:The anxiety,depression and VAS scores in the two groups on T2 were statistically significant lower than the corresponding results on T1(P<0.05). On T3,however, there were statistically significant differences between the two groups(P<0. 05). The total adverse reaction rate of group A was signif-icantly lower than that of group B(P<0. 05). The total effective rate of group A was significantly higher than that of group B(P<0. 05). Conclusion:GBP combined with tramadol and amitriptyline in the treatment of PHü patients with anxiety can effectively con-trol the pain of the patients,significantly reduce the scores of VAS and improve the quality of life of the patients.

Objective The use of extracorporeal membrane oxygenation (ECMO) as a treatment for the failure of cardiopulmonary function after cardiac surgery is increasing and has been reported to be 3% to 5% in the cases with congenital heart disease. We reviewed our experience with ECMO in children who received heart surgery for congenital heart disease and complicated with severe heart failure postoperatively. Methods Eight patients received ECMO, seven was due to the failure to wean from bypass and one had fulminant myocarditis. Import membrane oxygenator,veno-arterial mode ECMO and right atriumascending aortic cannulation were used in 7 cases and peripheral cannulation via femoral veno-artery route was used in 1 case.Supportive intervention persisted from 65 to 498 hours, with flow rate maintained at 80 to 120 ml per minute per kilogram body weight. Results Five patients died, with a mortality of 62.5%, and 3 cases discharged, with a survival rate of 38%. Bleeding occurred in 5 cases, thrombosis occurred in 2 cases, hemolysis was identified in 1 case and DIC was observed in 1 case.One case had liver failure and 2 cases had malnutrition. Oxygenator plasma leakage occurred in 2 cases. Mean arterial blood pressure increased significantly after the establishment of ECMO as compared with that before the procedure [( 60.2 ± 7.8 )mmHg vs. (48. 1 ± 5.2 ) mmHg, P≤0.05]. The arterial concentration of lactate decreased significantly, from (5. 1 ± 0. 8 )mmol per liter before ECMO to ( 3.6 ±0. 5 )mmol per liter after ECMO, P <0.05. Conclusion For patients who survived the congenital heart surgery and no residual anatomic deformity, ECMO can be used as early as possible as a treatment for severe heart failure which resulted from coexistent of left and right ventricular and pulmonary insufficiency. An overall mortality may be decreased by ECMO technique as it plays a substitution role for gas exchange in the lung. As a result, the concentration of oxygen and the airway pressure used during ventilation, and the resultant lung injury can be reduced. Appropriate strategies involve transfusion of fresh platelet and packed red blood cells, replacement of frozen plasma and blood products, as well as rational use of vasoactive drugs and heparin, and maintaining a stable internal environment. Following strategies are also recommended: using continuous arterio-venous hemofiltration and durable heparin-coated membrne oxygenator, reducing hemorrhagic complications, monitoring pressure on both side of the film, identifying plasma leakage carefully and reducing the mechanical complications.

OBJECTIVETo evaluate the feasibility and efficacy of unilateral pedicle screw fixation in treating thoracolumbar fractures through paraspinal approach.
METHODSFrom January 2006 to January 2009,21 patients with single level thoracolumbar fracture without neurological symptoms were treated with unilateral pedicle screw fixation through paraspinal approach. There were 14 males and 7 females,aged from 21 to 65 years old with a mean of 36.4 years. The duration from injury to operation ranged from 6 h to 5 d with an average of 3 d. According to the classification of Denis fracture, compression fractures happedned in 12 cases and burst fractures happened in 9 cases,including 1 case with T5 fracture, 2 cases with T7 fracture, 2 cases with T10 fracture, 3 cases with T11 fracture, 8 cases with T12 fracture, and 5 cases with L1 fracture. Based on the Flankel grade, all patients were classified as grade E. Anterior vertebral body height ratio, sagittal Cobb angle, condition of internal fixation failure, visual analogue score (VAS) were evaluated.
RESULTSAll patients were followed up from 12 to 36 months with an average of 20.5 months. No internal fixation failure was found. Anterior vertebral body height ratios at preoperative 3 days after operation and last follow-up were 54.3 +/- 2.8, 92.9 +/- 1.5, 93.8 +/- 1.7, respectively;sagittal Cobb angle at the three timepoints were (27.8 +/- 2.5) degrees, (5.3 +/- 0.8) degrees, (6.3 +/- 1.4) degrees, respectively; the difference was statistical significant (P < 0.05). VAS was (1.2 +/- 0.4) points at last follow-up and had obviously improved (P < 0.05).
CONCLUSIONTreatment of thoracolumbar fractures with unilateral pedicle screw fixation through paraspinal approach is safe with the advantages of micro-trauma and less blood loss,which can not only completely retain the posterior spinal complex structure, reinforce the spinal stability, raise the reductional quality, but also improve the strength of fixation and the distribution of stress force.
