ABSTRACT
Objective To investigate the effects of general anesthesia and hard epidural anesthesia on the incidence of postoperative cognitive dysfunction (POCD),serum S-100β and Aβ1-42 protein in elderly patients with transurethral resection of the prostate (TURP).Methods 120 cases of elderly male patients who wanted to implement TURP were enrolled in this study.From March 2014 to August 2016,60 patients underwent general anesthesia (general anesthesia group) and 60 patients underwent epidural anesthesia (hard epidural Group).The effects of two anesthesia methods on the cognitive function,serum S-100 β and Aβ1-42 protein were compared.Results There was no significant difference in mini-mental state examination (MMSE) score in preoperative,postoperative 12 h,postoperative 24 h,postoperative 72 h,and postoperative 1 week between hard epidural group and general anesthesia group (P ＞ 0.05).The MMSE scores at 12 h,24 h and 72 h after operation in both groups were significantly lower than those before operation in both groups (P ＜0.05).There was no significant difference in clock drawing task (CDT) score in preoperative,24 h after operation,72 h after operation and one week after operation (P ＞ 0.05).The CDT scores of both groups at 12 h,24 h,72 h after operation were significantly lower than those before operation (P ＜0.05).There was no significant difference in serum S-100β levels between the two groups at preoperative and 12 h,72 h after operation (P ＞0.05).Serum S-100β levels at 12 h and 72 h after surgery in both groups were significantly higher than those before surgery (P ＜ 0.05).There was no significant difference in preoperative and postoperative 12 h,postoperative between hard epidural group and general anesthesia group (P ＞ 0.05).Serum Aβ1-42 levels at preoperative,12 h and 72 h after operation in both groups were significantly lower than those before operation (P ＜ 0.05).There was not statistically significant in the incidence of POCD between hard epidural group [28.33 ％ (17/60)] and general anesthesia group [35％ (21/ 60)] (P ＞ 0.05).Conclusions There was no significant difference in the incidence of POCD between general anesthesia and hard epidural anesthesia group in elderly patients with TURP.The incidence of POCD in elderly patients was related to the decrease of serum S-100β and the decrease of Aβ1-42.
ABSTRACT
In order to implement the 'excellent doctor education training plan' for clinical medicine majors,a series of principles and measures were adopted to train medical students.On the basis of clearing ideas and goals of ‘excellent doctor education training plan',constructing cmriculum system based on basic clinical skills,innovatively constructing the practical teaching platform,optimizing practical teaching system,improving teaching methods,revising assessment and evaluation methods and employing an outstanding teaching team with reasonable structure,we constructed the talent training mode with ‘one goal,two processes,three combinations'.In conclusion,the talent training mode played an important role in the cultivation of medical talents in clinical medicine.
