Objective To investigate the effect of dexmedetomidine on median effective target effect-site concentration ( EC50) of sufentanil inhibiting body movement evoked by skin incision in patients undergoing bilateral subtotal thyroidectomy. Methods Thirty-nine ASA I or II patients of both sexes aged 20-64 yr with a body mass index of 20-25 kg/m2 undergoing bilateral subtotal thyroidectomy were randomly divided into 2 groups: control group (group C) and dexmedetomidine group (group D). The patients were premedicated with intramuscular phenobarbital 0.1 g and scopolamine 0.3 mg. In group D dexmedetomidine 0.6 μg/kg was injected iv over 10 min at S min before induction of anesthesia. Anesthesia was induced with target-controlled infusion (TCI) of propofol and sufentanil. The target plasma concentration of propofol was set at 3.0 μg/ml which was maintained until the end of operation. TCI of sufentanil was started at 10 min after initiation of propofol TCI. The initial target effect-site concentration was set at 0.20 ng/ml and decreased/increased by 20% in the next patient according to whether the patient's body moved or not within 1 min after skin incision. Laryngeal mask airway was inserted at 3 min after initiation of sufentanil TCI. Spontaneous breathing was maintained. Skin incision was made at 10 min after initiation of sufentanil TCI. The EC50 and 95% confidence interval (CI) of sufentanil inhibiting skin incision-evoked body movement were calculated with sequential method. Results EC50, of sufentanil was 0.1148 ng/ml (95% CI 0.1055-0.1249 ng/ml) in group D and 0.1454 ng/ml (95% CI 0.1339-0.1580 ng/ml) in group C, and was significantly lower in group D than in group C. Conclusion Dexmedetomidine 0.6 μg/kg infused iv before operation can reduce the EC50 of sufentanil inhibiting body movement evoked by skin incision in patients undergoing bilateral subtotal thyroidectomy.

Objective To explore the effect of glucose regulated protein (GRP)78 on the neuronal apoptosis after cerebral ischemia reperfusion injury in rats. Methods Middle cerebral artery ischemia reperfusion rat's models were used with the modified filament method. The expression of GRP78 in the ischemic penumbra tissue was detected by RT-PCR, Western blot and immunohistochemistry at different time points. Primary cultured rat's neurons were exposed to hypoxia and subsequently reoxygenation. Western blot was used to investigate the expression of GRP78. The changes of the neuronal apoptosis after overexpression of GRP78 induced by 2-deoxyglucose were detected. Results The expression of GRP78 in the ischemic penumbra tissue in model group was significantly increased (mRNA : 0.7367±0.0651, F= 477.160, P < 0.01 ; Protein : 0. 8129±0. 0748, F=39.857, P < 0.01). The neuronal survival status was increased after overpression of GRP78 (increased by 39.22% ± 0. 44%, t=46.374, P < 0.01) while the neuronal apoptosis was decreased (decreased by 16.60±1.02, t=7.530, P <0.01). Conclusion Focal cerebral ischemia reperfusion can induce endoplasmic reticulum stress which plays a role in the neuronal apoptosis. The increased expression of GRP78 may protect the ischemic tissue from neuronal apoptosis.
