  • Effects of Tianjiang Niuhuang powder on the epileptic model of pilocarpine rats

    ObjectiveTo observe the effects of Tianjiang Niuhuang Powder on cognition, seizure and hippocampal formation in epileptic model of pilocarpine rats.MethodsFouty SD rats were selected in this study. They were randomly divided into four groups (each group n=10), including a blank control group (group A) and three pilocarpine epilepsy model groups. The model groups were divided into Tianjiang Niuhuang Powder treatment Group (group B), Sodium valproate (group C) and model control group (group D) according to the different processing methods. The seizures number of discharges in the EEG monitor, cognitive ability were observed on the 7th, 14th and 21st day, The pathological sections of the brain and the neuronal damage in the hippocampal CA1 area were observed after the rats were sacrificed.ResultsThere was no significant difference in the number of spontaneous episodes, duration, and average number of discharges per minute between group B and group C (P>0.05). Compared with groups B and C, group D increased the number of episodes and increased duration. The number of discharges increased, the difference was statistically significant (P<0.05). Group A had no seizures. There were no significant differences in cognitive ability between groups A, B and C (P>0.05). Compared with group A, B and C, group D had poor cognitive ability (P<0.05). The number of surviving cells in the hippocampus CA1 region was significantly improved compared with the D group (P<0.05). Compared with the A group, the viable cells in the hippocampal CA1 region of the three experimental groups were significantly lower (P<0.05).ConclusionsTianjiang Niuhuang Powder can reduce seizures, improve cognition and effectively alleviate neuronal damage in hippocampal CA1 neurons in rats with epilepsy.

  • Early experience and learning curve of anatomatic lung resection by robotic-assisted thoracoscopic surgery

    ObjectiveTo summarize the surgical learning curve and evaluate the effectiveness, safety and feasibility of the robotic-assisted thoracoscopic surgery (RATS) by comparing with the conventional vedio-assisted thoracoscopic surgery (VATS).MethodsThe clinical data of 40 patients receiving robotic assisted thoracoscopic anatomic lung resection from March to June 2016 in our department were reviewed. There were 29 males and 11 females with the age of 54-78 (60.2±12.7) years in the RATS group, and 27 males and 10 females with the age of 52-76 (58.7±11.5) years in the VATS group. Lung space-occupying lesions were comfirmed by preoperative diagnosis. The operative time, blood loss, chest tube retention time, postoperative hospital stay and perioperative morbidity and mortality were analyzed. The safety and feasibility were evaluated, and the learning curve was summed up.ResultsOperative time, postoperative ventilation time, intraoperative blood loss, chest tube retention time, postoperative pain, average hospital stay, postoperative complication rate between two groups were not statistically significant. In the RATS group preoperative preparation time was longer than that of the VATS group (24.5 min vs. 15.6 min, P=0.003), and the rate of conversion to thoracotomy of the RATS group was lower than that of the VATS group (0 vs. 10.8%). There was no perioperative death in two groups.ConclusionRobotic-assisted thoracic surgery is safe and effective in the early learning process, and the learning curve can be entered into the standard stage from the learning stage after initial 10 operations.
