Objective To observe the effect of subarachnoid block with 0.5% bupivacaine at different temperatures during cesarean section.Methods 100 cases of elective cesarean section were randomly divided into room temperature group and heating group,50 cases in each group.Room temperature group: bupivacaine hydrochloride injection and glucose injection equilibrated group in a constant temperature thermostatic bath of 24 degrees thermostatic bath heating for above 30 min.Heating group: bupivacaine hydrochloride injection and glucose injection heated in the constant temperature thermostatic bath of 37 degrees thermostatic bath heatingfor above 30 min.Anesthesia was injected into the subarachnoid space at different temperatures to observe the anesthetic effect.Results The anesthesia increased rapidly, and the analgesia and muscle relaxation effects were better in the heating group than room temperature group, but the heating group had hypotension rate was higher than the room temperature group (36.0% vs.16.0%).There was no obvious difference between the incidence of adverse reactions such as nausea and vomiting in both groups.Conclusion Different temperatures of bupivacaine can be used safely for section anesthesia.The anesthesia effect of the heateding bupivacaine is faster, the anesthesia level is higher, the anesthesic and muscle relaxant effect is better.Bupivacaine at room temperature has relatively small effect on hemodynamics.

Objective To compare the effects of a single injection of palonosetron and tropise-tron to prevent postoperative nausea and vomiting (PONV ) in gynecological surgeries. Methods Sixty patients undergoing elective major gynecological surgeries with general anesthesia (Apfel score ≥ 3 ) were included and randomized to group P (palonosetron ) and group T (tropisetron),30 patients in each group.All patients received general anesthesia with tracheal intuba-tion,and palonosetron 0.25 mg or tropisetron 5 mg were injected before anesthesia respectively in two groups.Intravenous hydromorphine was delivered for postoperative analgesia in all patients. PONV were evaluated and followed up for 72 hours.The degree of PONV was recorded and the com-plete response rate (CR)and complete control rate (CC)were calculated.Results The degree of PONV in 0-24 h and 24-48 h was milder in group P than in group T (P <0.05),while in 48-72 h the degree of PONV was similar between the two groups.In group P,5 patients had vomiting postopera-tively with the failure period of treatment of (1 9.6±9.4)h,and no patients needed rescue treatments. While in group T,1 9 patients suffered from vomiting with the failure period of treatment of (20.6± 4.5)h,and rescue treatments were delivered 3 times in total.The CR and CC of preventing PONV in 0-24 h,24-48 h and 0-72 h were significantly higher in group P than in group T (P <0.05).The CR and CC of the two groups were comparable in 48-72 h postoperatively.Conclusion A preoperative single dose of palonosetron 0.25 mg is better than tropisetron 5 mg in preventing PONV within 48hours after gynecological surgery.

Objective To observe the effect of Wuyaojing granules(WYJG) on immunological function of mice.Methods Mice were randomly divided into six groups:the high-dosage WYJG group(6.0g/kg),the midst-dosage WYJG group (2.0g/kg),the low-dosage WYJG group(1.0g/kg),the Lindera aggregate group (0.9g/kg),the korean Ginseng group (2.0g/kg) and the normal control group(H2O).After a period of 30-day treatment,the effects of WYJG on the T lymphocyte transformations capacity induced by ConA,delayed hypersensitivity leaded by DNFB,the number of lymphocyte B,serum level of hemolysin and NK activity were observed. Results The high-dosage and the low-dosage WYJG could significantly increase T lymphocyte transformations capacity induced by ConA(P0.05).Conclusion WYJG can significantly increase T lymphocyte transformations capacity induced by ConA and strengthen delay hypersensitivity leaded by DNFB.

Objective To investigate the best time of the mesenchymal stem cells(MSCs) transplantation after myocardial infarction(MI),in order to provide prophase experimental basis for treatment of the diseases correlating to cadiocyte necrosis by cells transplantation.Methods Thirty New Zealand big-ears albino rabbits,which aging were older than or equal to 36 months were selected(a 36-month rabbit is the advanced age rabbit,equaling a person 60 years old).Model of MI was made by ligating anterior descending branch.The model rabbits were randomly divided into six groups(control group,1 d group,1-week group,2-week group,3-week group;and 4-week group,n=5).200 ?L cells after marked were drawed and injected in multiple positions of myocardium after MI in 1 d group,1-week group,2-week group,3-week group and 4-week group separately.The rabbits in control group were injected with saline of equal quantity.The cardiac functional parameters,blood flow rate of atrioventricular valve and the hemodynamics at eighth week in various groups were measured.Results Compared with control group,the treatment of MSCs transplantation for MI improved the heart function.The cardiac functional parameters,blood flow rate of atrioventricular valve and the hemodynamics in 1 d group was higher than those in control group(P0.05).The cardiac functional parameters,blood flow rate of atrioventricular valve and the hemodynamics in 1-week,2-weeks and 3-weeks groups were better than those in 1 d group(P0.05).Conclusion In the condition of the same cell-density but the different time of MI,the transplantation time window is 1 d-3 weeks after MI,which is advantageous to the amelioration of heart function,the best time of transplantation was 1-3 weeks after MI.

ObjectiveTo summarize and analyse the perioperative management especially theanesthesia of 20 kidney transplant recipients in non-transplant surgery. MethodThe anesthesia management of 20 kidney transplant recipients in non-transplant surgery was analyzed retrospectively. ResultsIn 20 cases, 1 case (5％) was performed under local anesthesia,4 cases (20％) were performed under intravertebral anesthesia and 15 cases (75％) were performed under general anesthesia. The operation time was 30-260 min, all cases were managed successfully. ConclusionIt is still a clinical challenge to deal with the surgical patients after kidney transplantation, and it needs fully understanding of the pathophysiological status of the patient and closely collaboration of transplant physicians, anesthesiologists and the surgeons.

ObjectiveTo observe the effect of penehyclidine hydrochloride (PHC) on serum interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α ) concentrations following tourniquet deflation in patients undergoing lower limb surgery.Methods Thirty adult patients,scheduled for unilateral lower limb surgery,ASA classification [ - Ⅱ grades,were divided into control group and research group by random number table,each group of 15 cases.Before anesthesia 30 min,PHC in intravenous infusion of 0.01-0.02 mg/kg in research group,the corresponding volume in intravenous infusion of 0.9% sodium chloride in control group.Peripheral venous blood samples were collected immediately before tourniquet inflation (T0,baseline),immediately before tourniquet deflation(T1),30 min (T2) and 60 min (T3) after tourniquet deflation.Serum IL-6 and TNF- α concentrations were measured by enzyme linked immunosorbentassay.ResaltsSerum TNF- α change at the same time point after tourniquet deflation was not statistically significant between two groups (P ＞ 0.05).Serum IL-6 concentration was decreased at each time point after tourniquet deflation compared with T0 in research group,while increased in control group.Serum IL-6concentration difference of T3 and T0 had statistically significant between research group and control group [ (-8.8 ± 5.6) ng/L vs.( 10.2 ± 6.7) ng/L,P＜ 0.05].ConclusionsPHC in advance can decrease serum IL-6 concentration after tourniquet deflation in patients undergoing lower limb surgery.

Objective To evaluate the effect of lithium chloride (LiCl) pretreatment on isoflurane-induced cognitive dysfunction and inflammatory response in hippocampus in aged rats.Methods Eighty 20-month-old male Sprague-Dawley rats,weighing 350-400 g,were randomly assigned into 4 groups (n =20 each):control group (group C),1.4％ isoflurane group (group I),100 mg/kg LiCI + 1.4％ isoflurane group (group L+ I),and 100 mg/kg LiC1 group (group L).Group I was exposed to 1.4％ isoflurane in 30％ O2-70％ N2 for 6 h,while group C was exposed to 30％ O2-70％ N2 only.LiCl 100 mg/kg was injected intraperitoneally once a day for 3 consecutive days and isoflurane anesthesia was performed on 4th day in group L + I.LiCl 100 mg/kg was injected intraperitoneally once a day for 3 consecutive days and then the rats inhaled 30％ O2-70％ N2 for 6 h on 4th day in group L.Blood samples were taken immediately after the end of anesthesia for blood gas analysis.Hippocampi were isolated 24 h after the end of anesthesia for determination of the expression of glycogen synthase kinase-3β (GSK-3β) and acetyl-NF-κB (Lys310) (by Western blot) and TNF-α,IL-1β and IL-6 mRNA (by RT-PCR).The levels of TNF-α,IL-1β and IL-6 were determined by ELISA and the contents of TNF-α,IL-1β and IL-6 were calculated.The cognitive function was assessed on 2nd day after the end of anesthesia.Results Compared with group C,the expression of GSK-3β and acetyl-NF-κB (Lys310) was significantly up-regulated,the expression of TNF-α,IL-1β and IL-6 mRNA and contents of TNF-α,IL-1β and IL-6 were increased,the escape latency was prolonged,and the time of staying at the original platform quadrant was shortened in group I (P ＜ 0.05).Compared with group I,the expression of GSK-3β and acetyl-NF-κB (Lys310) was significantly down-regulated,the expression of TNF-α,IL-1β and IL-6 mRNA and contents of TNF-α,IL-1β and IL-6 were decreased,the escape latency was shortened,and the time of staying at the original platform quadrant was prolonged in group L + I (P ＜ 0.05).Conclusion LiC1 pretreatment can improve isoflurane-induced cognitive dysfunction and inhibition of inflammatory response in hippocampus is involved in the mechanism in aged rats.

Objective To investigate the effect of melatonin on ketamine-induced apoptosis in hippocampal neurons of fetal rats.Methods Sixteen to eighteen day pregnant Sprague Dawley rats were anesthetized.The fetal rats were obtained under sterile condition and decapitated.The hippocampal neurons were isolated and primary cultured for 5 days.The primary cultured neurons were randomly divided into 5 groups (n =6 each):control group (group C),ketamine group (group K),and 1.0,2.5 and 5.0 mmol/L melatonin groups (groups M1-3 respectively).Ketamine with the final concentration of 1 000 μmol/L was added to the culture medium and the neurons were incubated for 3 h in group K.In groups M1-3,1.0,2.5 and 5.0 mmol/L melatonin were added to the culture medium,respectively,at 60 min before the addition of ketamine,and the neurons were incubated for 3 h.While the equal volume of normal saline was added instead in group C.The neuronal viability during the developmental phase was assessed by MTT assay.The mitochondrial membrane potential (Ψm) was measured by flow cytometry.The expression of cAMP response element binding protein phosphorylation (p-CREB (Ser133)),Bcl-2,Bax,and cytochrome C was detected by Western blot.Results Compared with group C,the neuronal viability and Ψm were significantly decreased,and the expression of p-CREB and Bcl-2 was down-regulated,while the expression of Bax and cytochrome C was up-regulated in group K (P ＜ 0.05).Compared with group K,Ψm was significantly increased in groups M2 and M3,and the neuronal viability was significantly increased,the expression of Bcl-2 was up-regulated,while the expression of Bax and cytochrome C was down-regulated in groups M1-3 (P ＜ 0.05).Conclusion Melatonin can protect the hippocampal neurons of fetal rats from apoptosis triggered by ketamine via regulating the expression of Bcl-2 and Bax,stabilizing Ψm,inhibiting the release of cytochrome C from mitoehondria,and preventing apoptosome formation.
