0.05). TNF-? in group EK and EKM was lower than that in group E (P0.05). Conclusions Ketamine can inhibit the release of TNF-? caused by LPS and increase myocardial cAMP level, protecting myocardium from sepsis. This may be one of the anti-septic shock mechanisms of ketamine. Combination of midazolam with ketamine does not affect the anti-septic shock property of ketamine.

Objective To investigate the inhibition of low-dose aprotinin on systematic inflammatory response during cardiopulmonary bypass. Methods Twenty-eight ASA Ⅱ-Ⅲ patients(male 13, female 15) undergoing valve replacement were studied. The age ranged from 27 to 55 years and body weight from 37 to 70 kg. CPB time ranged from 66 to 218 mm and aortic cross clamping time from 30 to 140 min . The patients were divided into two groups: control group(n=14) and aprotinin group(n = 14) Premedication included intramuscular phenobarbital sodium 0.1 g and scopolamine 0.3 mg. Anesthesia was induced with intravenous midazolam 0. lmg/kg, fentanyl 20-30?g/kg and vecuronium 0. 1-0. 12mg/kg, and maintained with intermittent bolus injection of fentanyl and vecuronium supplemented with isoflurane inhalation. In aprotinin group aprotinin 1?106KIU was infused after induction of anesthesia until thoracotomy, after thoracotomy aprotinin was infused at a rate of 2.5? 106 KIU/h and aprotinin 2. 5 ?106KIU was added to the prime fluid as suggested by Levy. Blood samples were obtained before anesthesia, before CPB and 1h and 24h after CPB for determination of CD11b and CD18 expression on the surface of neutrophil by immunofluoresence flow cytometry. Results The expression of CD11b or CD18 and CPB time were positively correlated(?= 0.644, 0.538, P0.05). 1 h after CPB CD11b/ CD18 expression increased significantly in the control group and was significantly higher than that in the aprotinin group, but at 24h after CPB only CD11b expression in control group was significantly higher than that in aprotinin group. In aprotinin group there was no significant difference in CD11b/CD18 expression between the four intervals.Conclusions CPB-induced systematic inflammatory response may be positively correlated with CPB time. Low dose aprotinin can inhibit the increase in CD11b/CD18 expression after CPB.

Objective To systematically review the efficiency of 18 F-FDG PET in glioma grading by using Meta-analysis. Methods Retrieval in PubMed and China National Knowledge Infrastructure (CNKI)was performed. Relevant papers concerning with glioma diagnoses with 18 F- FDG PET were selected. Paper quality was evaluated according to the standard of diagnostic test recommended by Cochrane Workshop. The data of glioma malignancy degree defined as semi-quantitatively and qualitatively were extracted from the papers. Meta-analysis was conducted with the Meta-Disc software to calculate pooled weighted sensitivity and specificity with 95% confidence interval (CI). Summary receiver operating characteristic (SROC) curve was performed and the areas under the curve (AUC) were calculated. Results Seven hundred and fifty-three patients from 17 papers ( 16 in English, 1 in Chinese) were included. Two hundred and seventy-two patients from 11 papers were using semi-quantitative (tumor to cortex ratio, T/C; tumor to white matter ratio,T/W) method and 481 patients from 9 papers were using qualitative method (visual observation, some of the papers had 2 or more methods). After heterogeneity test was done, different effect models were selected. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR) with 95% CI for T/C group was 0. 952 (95% CI: 0. 903 -0. 980), 0. 409 (95% CI: 0. 318-0. 504) and 11. 746 (95% CI:5. 368-25. 702) respectively. The pooled weighted sensitivity, specificity and DOR with 95% CI for T/W group was 0. 857 (95% CI: 0. 768-0. 922), 0. 538 (95% CI: 0. 431 -0. 642) and 22. 066 (95% CI:7. 077-68. 800) respectively. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR)with 95% CI for qualitative method was 0.810 (95%CI: 0.757-0.855), 0.870 (95%CI: 0. 819-0.911 ) and 15.282 (95% CI: 3. 716-62. 851 ) respectively. The AUC for T/C group, T/W group and qualitative method was 0.8604, 0. 8373 and 0. 8724 respectively. Conclusions Grading glioma by 18 F-FDG PET with semi-quantitative method may provide high diagnostic sensitivity. If qualitative method is used, the diagnostic specificity may be higher.

Cyclodextrin(CD) is gradually applied in the nonviral gene vector system,due to its biocompatibility and flexibility of tailing via structural modification,polymerization or supramolecular combination.The ideas and research progress of the CD,its low molecular derivatives,CD polymers and CD supramolecular combination in the field of norviral gene vectros were reviewed,and their "structure-safety-transfection efficiency" relationships were discussed.

Objective To explore the feasibility of establishing animal model of schistosomiasis through subcutaneous injection of IMDM liquid and intramuscular injection of IMDM liquid both of which contained the cercariae.Methods The mice were infected with schistosome cercariae by three different ways: subcutaneous injection(Group A),intramuscular infection(Group B) and the classical method: skin infection(Group C).Forty-five days post-infection, the mice were sacrified and the adult schistosomes were investigated. The serum IgG antibodies were detected by indirect ELISA in 15 and 45 days after infection. Results The recovery adult worm rates were 39.2% in Group A,32.3% in Group B and 72.8% in Group C,and there was a significant difference among them (P

Objective To research the effects of transcutaneous electrical stimulation (TES) on the expression of neurotrophin-3 (NT-3) and tumor necrosis factor-α (TNF-a) in the ventral horn of rats' spinal cords and in the injured region after spinal cord injury (SCI),and to explore the effects of TES on neuron reconstruction and functional recovery and their mechanisms. Methods Forty-eight Wistar rats were selected and divided using stochastic methods into a model group and a TES group.Using Allen's method,a complete SCI model was created at T9.Rats of the TES group were given TES treatment.Basso-Beattie-Brasnahan ( BBB ) ratings were used to evaluate locomotor function.Both groups were sampled at 1,3,5 and 7 days after the operation.Immunohistochemical techniques were used to detect the expression of NT-3 and TNF-α in the rats' spinal cords at the different time points. Results The post-operative BBB ratings of both groups showed an increasing trend.In the TES group the improvement was significantly better at 5 and 7 days than in the model group.The expression of NT-3 immuno-positive cells increased in both groups,peaking at 5 days post-operation,then declining at day 7.The expression of NT-3 positive cells at days 5 and 7 had increased significantly more in the TES group than in the model group.TNF-α immuno-positive expression increased with time in both groups,but in the TES group the expression increased substantially less than in the model group.At days 5 and 7 post-operation,the expression was significantly lower than in the model group. Conclusions TES can promote NT-3 expression in rats with SCI,inhibit the increase in TNF-α expression,and aid repair and reconstruction of neurons and related functional recovery.
