Objective: To investigate the effect of remifentanil with aniso-effective-site concentration propofol and comparison of bispectralindex(BIS) and cerebral state index(CSI), and evaluating explicit andimplicit memory during anaesthesia with propofol by target-controlledinfusion(TCI).

Cerebral state index monitoring during anesthesia induction with sevoflurane or propofol;

Objective To compare the accuracies of cerebral state index(CSI)and bispectral index(BIS)in sedation monitoring during target control infusion of midazolam.

A wakefulness loss cerebral state index(CSI) algorithm was developed to monitor the depth of anaesthesia,to predict different sleep stages,and then to provide a reference to estimate the depth of anaesthesia and postoperative recovery.

The binary relative evaluation method for measuring the technical innovation potentials is presented in this paper, we measure the comprehensive exponent state with the analytic hierarchy process (AHP) method, and measure the binary relative evaluation value with the BCC model involved in the data envelopment analysis (DEA) method.

To study the effect of sleep deprivation(SD)on cognitive brain function,we applied approximate entropy(ApEn)to assess the non-linear influence on brain functional states.
