Objective To investigate the effect of ulinastatin pretreatment on hippocampal CA1 region with ischemia-reperfusion (I/R) injury in rats and its mechanism. Methods A total of 90 male SD rats were randomly divided into the sham operation group (group S), group I/R and ulinastatin pretreatment group (group U), 30 rats in each group. The three groups were further divided into the reperfusion 2 h, 6 h, 1 d, 3 d and 7 d subgroups, 6 rats in each subgroup. Global cerebral I / R model was established by 4-VO method. The TdT-mediated dUTP nick end labeling (TUNEL) method was used to detect the neuron apoptosis in hippocampal CA1 region. The enzyme linked immunosorbent (ELISA) method was used to measure the serum concentrations of YKL-40, and the immunohistochemical method was applied to investigate expression of phosphorylated c-Jun N-terminal kinase (p-JNK) and phosphorylated extracellular-regulated protein kinase (p-ERK) in hippocampal CA1 region. Results The serum concentrations of YKL-40, the number of apoptotic cells and expression of p-JNK and p-ERK after reperfusion at each time point all showed significant differences among the three group (all P<0.05). Compared with group S, the serum concentrations of YKL-40, the number of apoptot ic cells and expression of p-JNK and p-ERK were significantly increased at each time point after reperfusion in group I/R (all P<0.05). Compared with group I/R, the serum concentrations of YKL-40 and expression of p-JNK were higher, while the number of apoptotic cells and the expression of p-ERK was lower at each time point after reperfusion in group U as compared with group I/R (all P<0.05). Conclusion Ulinastatin pretreatment can reduce I/R injury in rats hippocampus CA1 region, which may be associated with the increased serum concentrations of YKL-40, up-regulation of p-ERK expression, down-regulation of p-JNK expression and neuronal apoptosis.

Objective To observe the effects of target controlled infusion of remifentanil and constant infusion of dexmedetomidine on extubation response and emergence delirium during emergence from total intravenous anesthesia (TIVA) for pediatric patients. Methods 90 children undergoing adenotonsillectomy under TIVA were randomly divided into control group (group C) , remifentanil (group R) and dexmedetomidine group (group D). Dexmedetomidine was infused at the rate of 0.3μg·kg-1·h-1 in group D until extubation after anesthesia induction. At 2 minutes before the end of the surgery, propofol was ceased and infusion of remifentanil was stopped in group C and group D and maintained in group R at target organ concentration of 1.5 ng/ml until extubation. Mean artery pressure (MAP) and heart rate (HR) were recorded before Dex delivery (T0), the end of the surgery (T1), 1 min (T2) before extubation, during extubation (T3) and 1 (T4), 5 (T5), 10 min (T6) after extubation. Time from stopping propofol to extubation and opening eyes and cough reflex score during extubation were recorded. According to the Pediatric Anesthesia Emergence Delirium to mark the delirium of the patient per 5 minutes after extubation, the highest score was used to effective value, and at the same time, mark the degree of pain according to the modified Children’s Hospital of Eastern Ontario Pain Scale. Results Compared with T0, MAP and HR at T2-T6 in group C and at T5-T6 in group R were significantly higher (P<0.05), at each time point in group D were no significant difference (P>0.05). Compared with group C , MAP and HR at T2-T4 in group R and T2-T6 in group D were significantly lower (P<0.05). Compared with group R, MAP and HR at T5-T6 in group D were significantly lower (P<0.05). There was no significant difference in extubation time and opening eyes time between the three groups (P>0.05). Cough reflex score of group R and group D was significantly lower than group C (P<0.05), PAED and pain score of group D was significantly lower than group C (P<0.05) and group R (P<0.05). Conclusion Target controlled infusion of remifentanil (1.5 ng/ml) and continuous infusion of dexmedetomidine (0.3 μg·kg-1·h-1) can effectively inhibit extubation response and don’t increase the postoperative recovery time in pediatric adenotonsillectomy under TIVA. While continuous infusion of dexmedetomidine can decrease the incidence rate of emergence delirium, more applicable to infusion during emergence from TIVA for pediatric patients.

Objective To investigate the efficacy of heart rate variability in patients receiving off-pump coronary artery bypass grafting(OP-CABG) with remifentanil target controlled infusion for anasthesia. Methods A total of 65 patients undergoing elective OP-CABG were randomly divided into the target controlled infusion group(group Ⅰ, 32 cases) and constant infusion group(groupⅡ, 33 cases). The hemodynamic parameters and the plasma epinephrine, cortisol, blood glucose, lactate were detected and recorded at a series of time points: before induction(T0), after induction(T1), during intubation(T2), 2 min after sternum saw(T3), exposure and stabilization of the left anterior descending artery(T4), the circumflex or right coronary artery(T5), at the end of operation(T6), during extubation(T7), and 24 h after operation(T8) HRV indices were also recorded by frequency domain analysis: the total power, low frequency power, high frequency power and low frequency power / high frequency power,at each time point. Results The indices of heart rate, mean artery pressure, epinephrine and cortisol at T7 in the two groups were much higher than those at T0(all P < 0.05). The levels of blood glucose and lactic acid in the two groups increased at T3, and were higher at T5, T6, T7 in the group Ⅱ than those in group Ⅰ(all P < 0.05). HRV indices in the two groups all decreased after the induction, whereas high frequency power, the total power, low frequency power and low frequency power / high frequency power raised at T5 and T7, and the total power, low frequency power and low frequency power / high frequency power at T5 were much higher in the group Ⅱ than those in group Ⅰ(all P < 0.05). Conclusion Remifentanil target controlled infusion can suppress the stress response and maintain the balance of cardiac autonomic nervous system in OP-CABG by HRV.
OBJECTIVE:To investigate the effects of magnesium sulfate infusion on shiver in patients with subarachnoid blockduring surgery. METHODS:60 patients scheduled for elective transurethral prostatectomy after subarachnoid block were random-ized into control group and treatment group. Treatment group received an intravenous bolus of magnesium sulfate 60 mg·kg-1 viasyringe pump in 30 minutes,followed by a constant pumped infusion of 1.5 g·h-1. Motor blockade was evaluated by bromage mo-tor scale. Sensory block level was assessed by pinprick test. Shiver reaction was assessed after the completion of subarachnoid blockand side effects were recorded. RESULTS:Hypothermia was observed in all patients in treatment group and in 70.0% patients incontrol group(P<0.05) . The decrease in core temperature in treatment group was more significant than control group(P<0.01) .The incidence of shiver in control group(73.3%) was higher than in treatment group(10.0%)(P<0.01) . CONCLUSIONS:Mag-nesium sulfate infusion significantly relieves shiver in patients underwent transurethral prostatectomy after subarachnoid block but in-creases the risk of hypothermia.
Objective To assess the analgesic efficacy and safety of Parecoxib Sodium after transurethral resection of prostate.Methods 60 patients undergoing transurethral resection of prostate under spinal combined epidural anesthesia were randomly divided into group A and group B.Patients of group A were intravenous injected 40 mg Parecoxib Sodium that was dissolved in 2 mL Normal Saline before anesthesia induction 30 min.Patients of group B were intravenous injected 2 mL Normal Saline before anesthesia induction 30 min.Postoperative pain scores were evaluated at 30 min,1,2,4 and 6 hours after administration of each Analgesic,using a visual analogue scale(VAS).Furthermore,preoperative and postoperative hemoglobin(Hb) levels and hemostatic variables [prothrombin time(PT) and the international normalized ratio(INR)] were recorded in all patients.Results The score of VAS of group A at the time of T1,T2,T3,T4,T5 were lower than that of group B,there were significant decreases(P 0.05).There was no significant difference on the amount of resection tissue,operating time,preoperative-postoperative Hb levels and hemostatic variables between the two groups.There was no patient required blood transfusion after operation in the two groups.Conclusion Parecoxib Sodium of NSAIDs has not a contraindication to TURP and should be used for the control of postoperative pain.
Objective To investigate the effects of peritoneal resuscitation on liver function in rabbits with hemorrhagic shock. Methods Twenty-one male rabbits were randomly divided into 3 groups: no hemorrhagic shock group(Group A),conventional resuscitation group(Group B),and peritoneal resuscitation group(Group C).Rabbits in Group B and C were exsanguinated until mean blood pressure(MAP) reached 40 mmHg within 10 minutes.MAP was kept at 40 mmHg for 60 minutes prior to resuscitation with shed blood plus double hemorrhage volumes of sodium lactate.Meanwhile,2.5% clinical dialysis fluid,which was replaced with saline in Group A and B,was intraperitoneally injected in Group C.The alanine aminotransferase(ALT) and asparate aminotransferase(AST) were measured at baseline,60 minutes after shock,and 60 and 180 minutes after resuscitation.The livers were obtained for assessment of dry/wet weight ratio,malondialdehyde(MDA),superoxide dismutase(SOD),and the pathological change,3 hours after resuscitation. Results Significant reduction in ALT,AST and MDA was revealed in Group C,comparing with those in Group B(P0.05).Meanwhile,significantly increase of dry/wet weight ratio and SOD was revealed in Group C,comparing with those in Group B(P0.05).Furthermore,more prominent pathological change was observed in Group B,comparing with that in Group C.No significant difference in pathological change was observed between Group A and C. Conclusion Peritoneal resuscitation improves the liver function in rabbits with hemorrhagic shock.
【Objective】 To observe the changes of plasma endothelin(ET) and calcitonin gene-related peptide(CGRP) in elderly patients subjected to deliberate hypotension with prostaglandin E1.【Methods】 86 elderly patients scheduled for nasal endos copic surgery in general anesthesia were randomly divided into groups of prostaglandin E1(group P) and nitroglycerin(group N).Hypotension was induced with prostaglandin E1 and nitroglycerin through continuous infusion respectively,and the mean arterial blood pressure(MAP) was reduced to about 25%~30% reduction of baseline MAP.The MAP and heart rate(HR) were continuously monitored,and the venus blood samples were taken for the measurements of plasma LAC,ET,CGRP and the rates of ET/CGRP before controlled hypotension(T0),at drop to target blood pressure(T1),at 30 min when hypotension has been maintained(T2),at the end of hypotension(T3) and 30 min after the halt of hypotension(T4).【Results】 The HR of patients in group N after controlled hypotension significant increased,but that of in group P is no significantly difference.The HR in group P was significantly slower than group N(P 0.05).Compared with T0,the patients in groups N after controlled hypotensiion significant increased in ET,but that in group P has not only changed and significantly lower than group N(P 0.05).The CGRP of group P rised significantly at T2,T3,T4,nevertheless,that in group N was not significantly changed throughout observation.The ET/CGRP in group P have no increase;while in group N are raised significantly at T2,T3,T4.【Conclusion】 Prostaglandin E1 for controlling hypotension are more likely to maintain ET/CGRP balance that is helpful for elderly patients to maintaining the normal regulation of vascular function during induced hypotension.
OBJECTIVE:To investigate the effects of Xingnaojing injection on the cognitive function in elderly patients in early postoperative and recovery period after general intravenous anesthesia. METHODS:80 elderly patients with elective abdominal surgery after general intravenous anesthesia were randomly divided into Xingnaojing group(group X)and control group(group C) with 40 patients in each group. MiniMental State(MMS)detection was used to evaluate cognitive function before anesthesia and at 1 h,3 h,6 h and 24 h after operation. The content of S100ββ protein and IL6 were detected at different time points. RESULTS:MMS scoring of patients in two groups were decreased and reached the lowest point at 1 h after operation. In group X the score was decreased significantly at 1 h after operation(P<0.05)and recovered at 3 h after operation. In group C the score was decreased significantly at 1 h and 3 h after operation P<0.05). And the decrease of score in group C at 1 h,3 h and 6 h after operation was more significant than in group X(P<0.05). The level of S100ββ protein and IL6 was highest at the end of operation. The level of S100ββ protein in group C at 1 h and 6 h after operation and the level of IL6 at 1 h,6 h and 24 h after operation were all higher than in group X. CONCLUSION:Xingnaojing injection could promote analgesia in elderly patients with general intravenous anesthesia and improve cognitive function,which may be associated with inhibition effect of Xingnaojing injection on the secretion of S100ββ protein and IL6 and inflammatory reaction.
