Conclusion The result indicated that method C was an effective and simple method for indoor air disinfection.

Actovegin is a drug,which can improve cellular energy metabolism,especially glycometabolism.It has an insulin-like effect,such as increasing the uptake of glucose and activating glucose metabolic enzyme.In addition,it can inhibit the production of lactic acid.Actovegin was mainly applied to the treatment of Alzheimer disease initially,but now it is indicated more and more.

Objective To investigate the effects of thoracic epidural anesthesia and analgesia on cellular immune function and erythrocytes glycometabolism in the patients undergoing thoracic surgery.Methods Forty esophageal carcinoma patients,classified as ASA Ⅰ or Ⅱ,scheduled for elective thoracic surgery were randomly divided into two groups with 20 cases each：group A underwent general anesthesia plus thoracic epidural anesthesia （TEA） during thoracic surgery and received patient-controlled epidural analgesia （PCEA） with fentanyl and ropivacaine postoperatively;group B received general anesthesia during thoracic surgery and patient-controlled intravenous analgesia （PCIA） postoperatively. Venous blood samples were collected for the measurement of Th1,Th2 and the activities of PFK,G-6PD and AR before the induction（T0）,2 h after the initiation of the incision（T1）,and 4 h（T2）,24 h（T3）and 48 h（T4）after surgery. Results The Th1/Th2 ratio in both groups were decreased significantly after completion of surgery compared with baseline levels （P0.05）. At T2,T3 and T4 the Th1/Th2 ratio in group A were higher than group B. Compared with these before operation,the activity of PFK was decreased significantly and the activities of G-6PD and AR in erythrocytes were increased markedly at T3 in group B（P0.05）.But erythrocytes PFK,G-6PD and AR activity slightly changed in group A.Conclusion These findings show that thoracic epidural anesthesia and PCEA may inhibit Th0 cells to differentiate into Th2 cells,protect cellular immune function and moderate erythrocyte glucose metabolism changes.

Objective To assess the quality of randomized controlled trials(RCT)abstracts published in Journal of Clinical Anesthesiology by CONSORT for Abstracts.Methods Articles invol-ving human RCTs published from 2012 to 2013 were reviewed and searched through WanFang Med Online.Trials involving animal experiments,in vitro,RCTs without abstract,and meta-analyses were excluded.According to the CONSORT checklists for abstracts,the quality of abstracts for RCT were assessed.Results In total,392 RCT abstracts were analysed.The median word counts of ab-stracts was 364 (IQR 306-444),sample size was 60 (IQR 40-80).Almost all abstracts provided an appropriate description of conclusions (100%), numbers randomized (99.0%) and objective (99.0%).The majority of abstracts described interventions (94.6%)and participants (82.4%).Re-quirements present in less than 50% of the abstracts were details regarding trial design (46.2%)and harms (48.7%).The descriptions of randomization (13.3%),blinding (1.8%),methods-outcome (3.6%)and results-outcome (9.7%)were very low.Moreover,title,recruitment and numbers ana-lysed were not reported.Conclusion The quality of RCT abstracts and adherence to the CONSORT checklist for abstracts remains poor,and the CONSORT for Abstracts should be endorsed to improve the quality of RCT abstracts as early as possible.

Objective To investigate the effect of IL-1 7A on lipopolysaccharide (LPS)-induced neuroinflammation and fear conditioning test.Methods Among 70 male SD rats aged 18 months, firstly,thirty rats were randomly divided into five groups:control group(group A),LPS 6 h group (group B),12 h group(group C),24 h group(group D),48 h group(group E).Group A were injected intraperitoneally with normal saline and groups B,C,D and E were injected with LPS 500 μg/kg.Ani-mals of groups A,B,C,D and E were killed respectively after LPS injection and their hippoeampus tis-sue was detected for the concentration of IL-1 7A.Secondly,forty rats were randomly divided into 4 groups:control group(group O),IL-1 7A antibody group(group P),LPS group (group Q),IL-1 7A antibody+LPS group(group R).Group P and group R were injected intracerebroventricularly with IL-1 7A antibodies 3 μl (200 μg/μl),groups O and Q were injected equal volume of normal saline.30 min later,groups Q and R were injected intraperitoneally with LPS 500 μg/kg,groups O and P were in-jected equal volume of normal saline.24 h later,contextual fear conditioning test was performed. Then,all animals were killed and their hippocampus tissue would be detected for the concentration of TNF-αand IL-6,as well as the expression of Iba1-positive cells.Results The concentration of IL-1 7A of groups B,C,D and E increased significantly compared with group A (P <0.01 ),there was no difference between groups E and A.The freezing time of groups Q and R was significantly shortened than that in group O(P <0.01 or P <0.05 ),the freezing time of group R was significantly longer than that in group Q(P <0.01).The concentration of TNF-αand IL-6 of groups Q and R was obvi-ously higher than group O(P <0.01 ),the concentration of TNF-α and IL-6 of group R lower than group Q(P <0.01).The expression of Iba1-positive cells in hippocampal area CA1 of groups Q and R was obviously increased compared with group O(P <0.01).Compared with group Q,the expression of Iba1-positive cells in hippocampal area CA1 of group R were obviously decreased (P < 0.05 ). Conclusion IL-1 7A is implicated in the early stage of LPS-induced neuroinflammation and the chan-ging of freezing time in contextual fear conditioning in aged rats.

The present study was to examine the effect of stellate ganglion block (SGB) on bilateral regional cerebral oxygen saturation (rSO2) and postoperative cognitive function. Eighty patients undergoing selective coronary artery bypass graft with cardiopulmonary bypass (CPB) were randomly and equally divided into two groups. The patients in group S were given right SGB with ropivacaine, while the patients in group C were injected with normal saline. We compared the bilateral rSO2 after SGB. Minimum Mental State Examination (MMSE), Visual Verbal Learning Test (VVLT), and Digital Span Test (DST) were applied to observe the effect on cognitive function. We found that the incidence of postoperative cognitive dysfunction (POCD) 7 days after surgery in group S was lower than that in group C. The level of blocked side rSO₂ of S group were significantly higher before CPB time of rewarming than that before SGB (P < 0.05), much higher than corresponding non-blocked side rSO₂ before CPB (P < 0.05), and much higher than rSO₂ level in group C before CPB and after CPB (P < 0.05). The non-blocked side rSO₂ in group S before anesthesia were much lower than basic levels and those in group C (P < 0.05). It could be concluded from the above results that there was significant increase in the blocked-side rSO₂ compared to the non-blocked side and there was significant decrease in the incidence of POCD compared to the control group after SGB.

Objective To study whether suprachiasmatic nucleus (SCN) slices are able to induce the molecular oscillations in NIH/3T3 fibroblast. Methods SCN slices from 10-day-old SD rat and NIH/3T3 cells were co-cultured in a serum-free condition. 24h mRNA profiles of Per1 and Rev-Erbα were measured in NIH/3T3 cells using real-time PCR. Results After co-cultured for 6 days, ten SCN slices can induce the significant daily oscillation of Per1 and Rev-Erba mRNA expression in NIH/3T3 cells (P<0.01). The peak time Rev-erbα and Per1 were at CT5 and CT11 respectively. Rev-Erbα oscillations were significant even with two SCN slices and 2 days co-culture (P<0.05). In contrast, Per1 expression fluctuation was not observed until more than 6 days of co-culture and with six SCN slices (P=0.031). Conclusion Diffusible signals release from SCN slices can regulate molecular rhythms in cultured fibroblasts. Rev-Erbα and Per1 don't start to oscillate at the same time, and Rev-Erbα is more sensitive to SCN signal.

Objective To study the effect of acute hypervolemic hemodilution on expression of serum chemokine interferon-inducible protein 10 in patients undergoing total hip replacement.Methods Twenty ASA Ⅰ or Ⅱ patients undergoing elective total hip replacement were randomly divided into 2 groups (n=10 each):HES group and LR group.The patients in HES group received 6% HES 20 ml/kg in rate of 30 ml/(kg·h) after anesthesia.The patients in LR group received Ringer's solution 20 ml/kg in rate of 30 ml(kg·h) after anesthesia.The blood loss,blood transfusion and the time of operation were recorded.Venous blood samples were taken before anesthesia (T0),at the begining of operation (T1),30 min after operation (T2),and at the end of operation (T3),in determination of serum chemokine interferon-inducible protein 10.Results The blood loss and the blood transfusion in HES group were (560±90)ml and (200±100) ml,those were significantly lower than that in LR group[(810±110)ml and (600±200)ml].The IP-10 concentrations were significantly increased at T2～T3 as compared to baseline value at T0 in both groups,but were higher in LP group[(77.3±13.8) ng/L and (89.9±15.1) ng/L]than those in HES group [(62.8±13.6) ng/L and (65.4±10.2) ng/L,P＜0.05].Conclusions Acute hypervolemic hemodilution can abate blood loss and blood transfusion during total hip replacement operation.Preoprative infusion with hydroxyethyl starch can attenuate the immunological depression during operation and anesthesia.

Objective To study the effect of acute hypervolemic hemodilution on expression of plasma bac-tericidaL/permeability-increasing protein (BPI) in patients undergoing total hip replacement. Methods Twenty ASA Ⅰ-Ⅱ patients undergoing elective total hip replacement were randomly divided into two groups (n=10 for thesia. The blood loss,blood transfusion and the time of operation were recorded. Venous blood samples were taken before anesthesia (T0) ,at the begining of operation (T1) ,30 min after operation (T2) ,and at the end of operation (T3) for determination of plasma bactericidal/permeability-increasing protein. Results The blood loss and the blood transfusion in HES group were significantly lower than that of LR group[blood loss: (560±90)ml vs (810±110) ml and blood transfusion: (200±100) ml vs (600±200) ml,t=5.562 and 5.657,P<0.001]. The plasma BPI concentrations in HES group were significantly increased at T2～T3 as compared to baseline value at T0 [(8.9±1.6)μg/L,(13.4±1.2)μg/L and (4.9±1.2)μg/L,P<0.05]. The plasma BPI concentrations in LR group were significantly increased at T2～T3 as compared to baseline value at T0 [(7.3±1.2)μg/L,(9.9±0.8) μg/L and (5.0±1.1)μg/L,P<0.05],but were lower than those in HES group (t=2.530 and 7.674,P=0.021 and 0.001 ). Conclusion Acute hypervolemic hemodilution with 200/0.5 hydroxyethyl starch can reduce blood transfusion during total hip replacement operation and also can increase the BPI level which would beneficial for the immunological function.
