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 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 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 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.

OBJECTIVE:To provide reference for promoting clinical rational application of Xueshuantong for injection(lyophi-lized). METHODS:By hospital centralized monitoring method,all medical records were retrieved from Hospital Information Sys-tem of our hospital,who received Xushuantong for injection(lyophilized)from Aug. 7 to Oct. 6 in 2015;general information of patients'drug information,drug utilization and the occurrence of ADR were traced and recorded by clinical pharmacists to evaluate the rationality of clinical utilization of Xushuantong for injection(lyophilized). RESULTS:Totally of 1014 medical records were included in the study. Xueshuantong for injection(lyophilized)was mainly used for fracture,cerebral infarction,coronary disease, cataract and other disease. 22 clinical departments as orthopedics department,neurology department,cardiology department and ophthalmology department were involved,accounting for 56.41% of total. For the patients receiving Xushuantong for injection(ly-ophilized),the average age was 63.12 years,the average course was 11 days and dose was 100-500 mg/time. They were given medicine intravenously once a day,and 0.9% Sodium chloride injection was used as solvent (93.29%). There were 10 kinds of drugs for drug combination averagely. The incidence of ADR was 5.92‰,and all ADR resulted from same batch of drugs (No. 15040211);ADR mainly manifested as erythra,erythema,pruritus,chills,etc. In terms of irrational drug use,the incidence of overlong treatment course was 17.85%;that of inadequate solvent dose was 13.71%;that of fast dripping rate was 7.59%;that of unsuitable solvent selection was 0.69%;that of drug use with no indication was 0.39%. CONCLUSIONS:Xueshuantong for injec-tion(lyophilized)is widely used in middle-aged and elderly in the clinic. There are many varieties and irrational drug use. The oc-currence of ADR is properly related to age,treatment course,solvent,dripping speed,product quality and other factors. Clinical pharmacists are required to monitor drug use,promote the rationality of drug use and reduce the occurrence of ADR.
