However, effective advances remain lacking. Hyperbaric oxygen preconditioning has proved to protect vital organs, such as the heart, liver, and brain. Recently, it has been introduced and widely studied in the prevention of postoperative cognitive dysfunction, with promising results. However, the neuroprotective mechanisms underlying this phenomenon remain controversial. This review summarizes and highlights the definition and application of hyperbaric oxygen preconditioning, the perniciousness and pathogenetic mechanism underlying postoperative cognitive dysfunction, and the effects that hyperbaric oxygen preconditioning has on postoperative cognitive dysfunction. Finally, we conclude that hyperbaric oxygen preconditioning is an effective and feasible method to prevent, alleviate, and improve postoperative cognitive dysfunction, and that its mechanism of action is very complex, involving the stimulation of endogenous antioxidant and anti-inflammation defense systems.展开更多

Methods： Totally 13 patients were been enrolled in the study. Before operation, none of our patients presented with spinal cord syringomyelia. The mean follow-up duration was 6 years （range 2-10 months） by MRI. Four of the 13 patients after spinal cord tumor removed operation, 3 patients after spinal trauma operation, 2 cases had scoliosis before, 2 cases were cervical spondylotic myelopathy and 2 cases had tethered cord syndrome before operation. MR features of pre- and post-operation on all patients were been studied in contrast with surgical results and clinical symptoms. The radiology diagnostic was made by 3 different radiologists respectively. The characteristics of length, width, signals, shape of cavity and spinal cord position as well as subarachnoid shape were focused on. Results： All the patients had no syringomyelia on MRI before operation. The spinal cord of 7 patients showed persist compression and 2 patients had tethered cord before operation. MRI features of syringomyelia after operation in our cases showed longitudinal cavity with syrinx fluid had T1 and T2 relation characteristics of cerebrospinal fluid （CSF）. The mean length was 5.5 spinal segment, 4 cord of 13 patients presented cord compressed from anterior materials, 4 occurred postoperative adhesion to the back of lumbar spinal canal and spinal cord of 1 cases clung to the front wall of cervical spinal canal. Conclusion： The mechanism of syringomyelia in the patients after spinal surgical intervention may be the persisting compression or intention of the spinal cord in the period of pre- or post-operation. The edema, cyst, malacia of spinal cord are the most important lesions and risk factors resulted in the syringomyelia.展开更多
Objective The aim of the study was to probe into the impacts of the times of preventive transcatheter arterial chemoembolization (TACE) after operation treatment for patients with primary liver cancer on their survival.

According to different methods, we separate patients into two groups, and each group is 150 patients. The one is test group （3D laparoscopic surgery）, and the other is control group（2D laparoscopic surgery）. Observing two groups for some factors, such as probability of surgical injury, post-operative exhaust time, catheterization time, time of drainage tube placement and hospital time. Result： The magnification of3D laparoscopy image is significantly better than 2D laparoscopy. Error damage fraction of test group（2. 00%） is lower than control group （28.00%）, which effectively reduces the probability of total surgical errors and provides more accurate operation. At the same time, exhaust time, catheterization time, time of drainage tube placement and hospital time of test group are significantly lower than the control group, statistically significant （p〈0.05）. Conclusion： 3D laparoscopic surgery has characterizations of easy operation, small window, fast recovery and small probability of complications occurrence. The HD vision is widen to improve the level of minimally invasive surgery and it is worthy of clinical application.展开更多
