Methods Three kinds of disinfection methods were carried out (method A: wiping surfaces of floor and walls of room with water and ultraviolet irradiation, method B: wiping surfaces of floor and walls with chloro-disinfectant and ultraviolet irradiation, method C: wiping surfaces with chloro-disinfectant and spraying chloro disinfectant containing chlorine) and the effectiveness of different disinfection methods was compared. Results The result showed that all of the three methods could decrease natural fallen bacteria count in isolated room air to up to the standard, and the disinfection effectiveness of method C was better than the method A and method B. Conclusion The result indicated that method C was an effective and simple method for indoor air disinfection.

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.

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 investigate whether angiotensin Ⅱ (AngⅡ) can regulate the expression of MIF in macrophages via the NF-κB pathway. Methods Western Blot, real time RT-PCR and ELISA were used in the present study. Results Western blot result showed that the expression of NF-κBp65 gradually increased with the increase of the concentration of AngⅡ. Results of real time RT-PCR and ELISA revealed that MIF mRNA expression and the content of MIF were significantly higher in AngⅡ group than those in the control group. PDTC could reverse the effect of AngⅡ on MIF mRNA expression and MIF secretion in macrophages. Conclusion AngⅡ can promote MIF mRNA expression and MIF secretion in macrophages via the NF-κB signaling pathway.

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.
