ABSTRACT
Objective To analyze the safety of atrial septal defect closure using Da Vinci surgical system. Methods Totally 23 atrial septal defect patients hospitalized from July to December 2016 underwent atrioseptopexy by using Da Vinci surgical system. The effect of atrioseptopexy was observed under cardiopulmonary bypass conditions. Results All the patients had the operation completed successfully, with the operating time being (2.8 ±0.5)h, the intraoperative cardiopulmonary bypass time being (35.4±18.4)min, aortic clamping time being (25.9±8.4)min, postoperative mechanical ventilation time being (5.7±1.5)h, amount of thoracic drainage fluid from 50 to 300 ml and postoperative hospital stay being (7 ±5.1)d. The follow-up 1 and 3 months after discharge showed there were no complications and death occurred, and the examinations by chest X-ray film and heart color ultrasound found no abnormality. Conclusion Da Vinci surgical system gains advantages in safety, reliability, patient satisfaction, operative incision and surgical trauma, and thus is worthy promoting clinically.
ABSTRACT
AIM:To investigate the effects of vinpocetine on inflammation of brain in intracerebral hemorrhage ( ICH) rats and to explore the underlying mechanisms .METHODS:All rats were randomly divided into sham group , ICH group, ICH with low dose of vinpocetine treatment group , ICH with medium dose of vinpocetine treatment group , and ICH with high dose of vinpocetine treatment group .Except sham group , the rats in other groups were injected with type VII col-lagenase to establish ICH model , and then the rats in vinpocetine treatment groups were received vinpocetine at 0.5, 1.0 or 1.5 mg/kg by intraperitoneal injection once a day for 7 days.After corresponding treatment , the impairment of neurological function in the rats was scored and the water content of the brain tissues was measured .Moreover, the activity of myeloper-oxidase (MPO) was determined by ELISA, and the protein expression of Toll-like receptors 4 (TLR4), nuclear factor-κB (NF-κB), intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molcule-1 (VCAM-1) in the brain tissues was determined by Western blot .RESULTS: Compared with ICH group , vinpocetine treatment significantly de-creased the scores of the impairment of neurological function and the water content of the brain tissues .Moreover, the activ-ity of MPO and the protein expression of TLR4, NF-κB, ICAM-1 and VCAM-1 were also reduced after vinpocetine treat-ment (P<0.05).CONCLUSION:Vinpocetine improves neurological function in ICH rats via suppression of inflamma -tion by inhibiting NF-κB signaling and expression of ICAM-1 and VCAM-1.
