Control group is fifty ones;3,Statistical Analysis:Spss11.5 statistical software will be applied to record the data. Logistic stepwise regression analysis will be applied to analyse the influencing factorsResult:1,The relevance was significant between the pre-operative hypertension, old age and preoperative depression with the occurrence about the postoperative cognitive dysfunction(P<0.05);2,Postoperative cognitive dysfunction occurred in 15 patients (30%) in control group and 5 patients (10%) in trial group. The incidence of postoperative cognitive dysfunction was significantly reduced in trial group compared with in control group (P < 0. 05 ). To compare with the two groups, determine the concept, orientation and structure of the indicators in the neuropsychological testing have significant improvement and are obviously change (P < 0. 05 ). To compare with the same group in the surgery of before and after, the indicators in the neuropsychological testing of trial group after intervention are not obviously change.
