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 study mechanism and clinical meaning of endothelin(ET) and neuron specific enolase (NSE) in patients with acute stroke.Methods The contents of ET and NSE in blood and cerebrospinal fluid were measured by RIA in patients with acute stroke, and correlation analysis of the contents of ET and NSE with different lesion area,severe degree and different period of the disease was performed.Results The contents of ET and NSE in acute cerebral hemorrhage and cerebral infarction groups were significantly higher than those in control group ( P

?Dry eye is a common eye disease around the world, which has highly incidence. Although there are many treatment measures for dry eye, the clinical effect is not satisfactory. There is a close relationship between inflammation and dry eye, so the researchers pay more attention on anti -inflammatory therapy, such as fluorometholone. To explore the effect of anti -inflammatory medicine on dry eye, put forward the problems and shortcomings as well, lay the foundation for further study, and provide a strong theoretical basis for the clinical use of anti-inflammatory drugs in the treatment of dry eye, the author summarizes the clinical and experimental research progress of fluorometholone on dry eye in China and abroad.

Background Trachoma is a common infectious eye disease,and its incidence is associated with region,economy and sanitary condition.To survey the prevalence status of an area is very important for the prevention and treatment of trachoma.Objective Aim of this study was to survey the prevalence of trachoma in primary and secondary school students of Chifeng Keshiketengqi,and to investigate the relationship between the prevalence of trachoma with age,gender,ethnicity and living environment.Methods This was a cross-sectional study.According to cluster random sampling method,2067 students were drawn from 10 primary and secondary schools,including 1061male and 1006 female.The age of students ranged from 6 to 17 years old,with the average age (12.53 ± 2.31)years.In the taken samples,Han students were 1768,and Mongolian students were 299;the agricultural and pastoral students were 1209,and the urban students were 858.The general life factors associated with trachoma were surveyed by questionnaire.Trachoma was diagnosed and graded based to 1987 WHO Simplified Trachoma Grading Standards.Eye examinations included visual inspection,eyelids,conjunctiva and cornea neovascularization under the slit lamp microscope,and the clinical data were recorded and collected.The results were statistically analyzed by SPSS13.0 software.Results According to the sampling proportion of 10.05％,2153 students were included and 2067 students participated in this study with the response rate 96％.Trachoma was diagnosed in 972 students with a morbidity 47.0％.The prevalence rate of trachoma was increased with the ageing,and a statistically significant difference was seen among the 6-8 years group,9-11 years group,12-14 years group and 15-17 years group (x2 =11.043,P =0.011),and the prevalence of trachomatous infiltration was significantly higher than that of trachomatous folliele (x2=11.493,P＜0.05).The prevalence rate of trachoma in Han and Mongolian students was 45.8％ and 54.5％,showing a significant difference between them (x2 =6.228,P =0.013).In addition,statistically significant differences also were found in the prevalence rate of trachoma between the pastoral areas students and urban students (56.1％ vs.39.7％,x2=30.226,P =0.000),but no significant difference was seen between male and female (47.0％ vs.46.9％,x2 =0.000,P =0.995).Conclusions The trachoma prevalence rate is relatively higher in the primary and secondary students in Chifeng Keshiketeng.These results offer a basis for the prevention and treatment of trachoma.

Objective To assess the carotid elasticity using wave intensity(WI) in subjects with different plasma glucose level.Methods 107 subjects were enrolled in this study,according to their plasma glucose levels,subjects were categorized as normal plasma glucose group (group A),normal plasma glucose in higher level group (group B) and pre-diabetes group (group C).Carotid WI examination was performed and analyzed.The parameters included magnitude of the peak during late systole (W2),negative area during the mid-ejection (NA),and stiffness parameter (β),pressure strain elasticity modulus (Ep),arterial compliance(AC),augmentation index(AI),one point pulse wave velocity(PWVβ).Results Compared to group A,W2,β,Ep,PWVβ increased significantly while AC decreased in group C(P ＜0.05),but there was no obvious difference of NA between two groups.Furthermore,this statistically difference was not found in group B(P ＞0.05).Conclusions Carotid elasticity have been altered in pre-diabetes group which can be evaluated by WI,but no marked change is observed in normal plasma glucose of higher level group.
