ABSTRACT
Objective To evaluate the clinic effects of perioperative psychological intervention combined appropriate sedation by target-controlled infusion of midazolam during operation via symptom check List 90 (SCL-90) and observers assessment of alertness/sedation scale (OAA/S) in patients undergoing thumb or finger reconstruction.Methods Eighty patients undergoing thumb or finger reconstruction were randomly divided into group A,B,C,and D (n =20 cases per group).All patients were received brachial plexus block and spinal-epidural combined anesthesia.Patients in group A were given perioperative psychological intervention combined appropriate sedation by target-controlled infusion of midazolam during operation; patients in group B were received routine treatment; patients in group C were given perioperative psychological intervention; and patients in group D were sedated with midazolam during operation.The vital signs and the scores of OAA/S were observed during operation.The scores of visual analogue scale (VAS) and SCL-90 were recorded after operation.Results The OAA/S grade in groups A and D were stability than that in groups B and C (P ＜ 0.05) ; the scores of VAS and the results of psychological status assessment by SCL-90 in group A were superior to groups B,C,and D (P ＜ 0.05).Conclusions Perioperative psychological intervention combined appropriate sedation in operation on thumb or finger reconstruction is a excellence anaesthesia processing method.It might have beneficial effects on postoperative recovery profile,and strengthen the tolerance to pain and improve the patient's psychological status during operative period.

ABSTRACT
ABSTRACT AIM To investigate the effect of ch-itosan on protein kinase C (PKC) activitives and diacyl glycerol(DAG)concentration in murine peritoneal macrophages. METHODS A new ion-pair reversed-phase high liquid chromatography and ra-dioimmunoassay were used to determinate the activity of PKC and the concentration of DAG respectively. RESULTS ( 1) Chitosan induced activation and translocation of PKC in murine peritoneal macrophages. The peak time was 25 min and the activity of PKC came back the basic level at 1. 5 h. (2)Chitosan increased the production of DAG in murine peritoneal macrophages. The peak time was 30 s and the concentration of DAG came back the basic level at 3 min. CONCLUSION The im-munopoteniating effect of chitosan may be associated with the channel of DAG /PKC.
