Stimuli-sensitive drug delivery system (SSDDS) is an novel drug delivery carrier.It is sensitive to either the internal physiopathologic changes (pH,temperature) of the body or external stimulus signal (ultrasound,magnetic signal) and controls the release of the drugs that it carries according to the variation of physicochemical property which stimulated by the signals.SSDDS can be prepared from hydrogels,liposomes and magnetic nanoparticles.In contrast to non-stimuli-responsive drug delivery system,SSDDS has remarkable advantages including feedback regulation,stronger controllability and targeting therapy.This paper will review the advancement in stimuli-responsive drug delivery system in recent years.

According to the practice of discipline construction in Guangdong Gollege of Pharmacy, three principles must be followed:the character of college and the relationship between college and local economical development should be clear, educational resourcesmust be made full use of and rationally disposeds and new disciplines can be established if they are suitable for social desire. Contentand goal of mechanism about discipline regulation have also been designed.

Objective The present study was undertaken to investigate the properties of nonlinear dynamics of EEG and the changes in depth of anesthesia with real-time approximate entropy (ApEn) and complexity (Cx) nonlinear indexes monitoring during anesthesia. Methods EEG was recorded in 65 in-patients. They were randomly divided into 4 groups: isoflurane, sevoflurane, desflurane (n=15, respectively), and propofol intravenous anesthesia (n=20) groups. The EEG derived parameters ApEn and Cx non-linear indexes were calculated simultaneously during the whole operation including rest state with eyes closed, anesthetic induction, intraoperation, recovery, post-operation awaking. Results ApEn and Cx nonlinear indexes remained the highest during rest state. Both of them kept decreasing during anesthetic induction. They dropped to a relative lower value and leveled off in the intra-operation period. Both of them rose gradually during recovery period and returned to a high level in the post-operation awaking period (correspondingly, ApEn: 0.87, 0.78, 0.55, 0.64 and 0.83. Cx: 0.58, 0.54, 0.38, 0.46 and 0.57). Conclusions With ApEn and Cx non-linear indexes, changes in depth of anesthesia from EEG signal could be real-timely monitored and precisely measured. Nonlinear dynamic analysis might provide us with more information about consciousness and cognition during general anesthesia.

To promote quality of the whole nursing,build harmonious relation of nurse and patient is basement.Nurse how to make language art utilize at the interflow of nurse and patient,to promote understanding and sustain between nurse and patient,improve cure,nursing effect,reduce contradictory of nurse and patient is the key of building harmonious relation of nurse and patient.

Objective To study the effects of russel viper venom X(RVV X)on blood coagulation protein.Methods We divide diluted protein into control and RVV-X groups,then use chromogenic substract assay to detect the activation effect of RVV-Ⅹ on coagulation factor Ⅶ,Ⅸ,Ⅹ and antithrombin,plasminogen,with or without activator.Results In RVV-Ⅹ group,the coagulation factor Ⅶ, Ⅸ and plasminogen displayed weakly enhanced chromogenesis,all P
