Objective to investigate the therapeutic efficacy of multiple-point injection with absolute alcohol and pinyangmycin under digital fluoroscopic guidance for superficial venous malformations. Methods By using a disposal venous transfusion needle the superficial venous malformation was punctured and then contrast media lohexol was injected in to visualize the tumor body,which was followed by the injection of ethanol and pinyangmycin when the needle was confirmed in the correct position. The procedure was successfully performed in 31 patients. The clinical results were observed and analyzed. Results After one treatment complete cure was achieved in 21 cases and marked effect was obtained in 8 cases,with a total effectiveness of 93.5%. Conclusion Multiple-point injection with ethanol and pinyangmycin under digital fluoroscopic guidance is an effective and safe technique for the treatment of superficial venous malformations,especially for the lesions that are deeply located and ill-defined.

Objective To evaluate the relationship between cranial CT characteristics and prognosis after first-ever primary supratentorial intracerebral hemorrhage (PSICH). Methods The data of clinic and CT in patients with first-ever PSICH were registered prospectively and followed up for 6 months. The relationship between the prognosis and the clinic data was analyzed using univariate and multivariate Logistical regression analysis.Results (1) The volume of hematoma was an independent CT predictor of death at 1st, 3rd and 6th month. (2) Both the volume of hematoma and secondary ventricular hemorrhage were independent CT predictors of death/disability at 6th month.Conclusions (1)The volume of hematoma can be used to predict death in patients with PSICH.(2)The volume of hematoma and secondary ventricular hemorrhage can be used to predict the death/disability rate of PSICH.

Objective The aim of this study is to address learning curve and clinical outcomes of totally robotic atrial septal defect repair on the basis of a single - center experience.Methods 54 cases of atrial septal defect (ASD) were repaired using “da Vinic S surgical system on arrested ( group Ⅰ,54 cases) or beating heart ( group Ⅱ,40 cases) from January 2007 to December 2010.Learning curves were assessed by means of regression analysis with logarithmic curve fit.The effect of operative variables on clinical outcome was analyzed by linear by regression using the Spearman's rho coefficient.Results All cases were accomplished successfully without complications.No residual shunt was detected at intraoperative or postoperative echocardiography.Significant learning curves were noted for corss clamp time in group Ⅰ:y (min) =68.741 -8.283 (n) (x)( r2 =0.489 ; P < 0.01 ) ; the operation time in group Ⅱ:y (min) =355.51 - 56.29 (n) (x) ( r2 =0.581 ; P < 0.01 ).No correlation was detected between operation time,cardiopulmonary bypass time,or cross clamp time and intubation time,intensive care unit stay,or total length of stay.Conclusion The robotic atrial septal defect repair can be performed safely.The learning curves is steep and the longer cardiopulmonary bypass times,operation time or cross clamp time had no negative impact on intraoperative and postoperative outcome.

The microstructure of cationic cyclopeptide (TD-34) treated Caco-2 cell membrane was observed, and we discussed the relationship between membrane structure and insulin transmembrane permeability. Atomic force microscope (AFM) was used to observe living cell membrane in air condition and tapping mode. Results showed that the surface of Caco-2 cell membrane treated with TD-34 lost its smoothness and nearly doubled its roughness. Apparent permeability coefficients (P(app)) of insulin in Caco-2 cell monolayers increased 2.5 times. In conclusion, AFM can be used to observe microstructure of cationic cyclopeptide treated cell membrane and cationic cyclopeptide enhanced insulin delivery across Caco-2 cell membrane by increasing membrane fluidity.

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.
