BACKGROUND:Manual reduction for external fixation of distal radius fractures can achieve good outcomes.
OBJECTIVE:To carry out the bibliometric analysis on manual reduction for external fixation of distal radius fractures.
METHODS:Literatures concerning reduction for external fixation of distal radius fractures were retrieved in CNKI database from 2003 to 2012. The keywords were“external fixation;distal radius fractures”. Duplicate and irrelevant articles were eliminated, and a total of 408 articles were retrieved. A bibliometric analysis of these 408 articles was performed in terms of publishing time and number, subject categories, source journals, research institutions, times cited and download frequency.
RESULTS AND CONCLUSION:Literatures concerning manual reduction for external fixation of distal radius fractures exhibit an upward trend in number. In 2012, there were 85 relevant articles. In the past 10 years, 18 relevant articles have been published in Chinese Journal of Traditional Medical Traumatology&Orthopedics, which is the most. There are not many relevant studies in various research units, only 1-7 articles published per unit, and five articles are funded.

Objective To study the clinical application of the complete audiologic evaluation battery consisting of ABR,ASSR and behavioral audiometry in sound field for the identification of sensorineural losses in children.Methods In the study 48 children were divided as group PTA of the children assessed by pure tone audiometry and ABR and ASSR test,and group BA of the children unable to perform on behavioral evaluations.Results The analysis of the audiometric results of group PTA showed significant correlation between the ASSR thresholds and pure tone thresholds(P＜0.01) at various frequencies.The correlation coefficients were 0.75,0.76,0.76,and 0.83 at different frequencies.The ASSR-PTA linear regression was utilized.The comparison of the ABR and ASSR results of group BA indicated that 23 ears responded in ASSR but without responses in ABR.Those without ASSR responses also had no ABR There were 116 tests in total four frequencies for the 29 ears.83 responses were obtained from ASSR,89 responses from behavior audiometry and 96 from the use of the both tests.Conclusion The comprehensive audiologic evaluation battery could be used to test younger children with severe heating loss children as compared to the pure tone audiometry alone.More detailed data can be obtained thus from children to assist in rehabilitation in a more effective mariner.

Obgective To analyze the relevant risk factors of recurrent wheezing(≥3 attacks) in the first 3 years of life.Methods Wheezing,respiratory sounds,risk factor were used as key words to retrieve papers in Chinese literature databases including Sinomed,Wanfang and Weipu databases.The same strategy was used to retrieve English papers in English literature databases including PubMed,Cochrane library and Embase.Time range was from 31th May 2004 to 1 rd June 2014.The execution of quality evaluation of the included documents was in compliance with Newcastle-Ottawa Scale and cross-sectional study standard recommended by Agency for Healthcare Research and Quality.The evidence quality evaluation was conducted with GRADEpro and followed by the Meta analysis with RevMan 5.2.R~ults A total of 13 studies were included in this Meta-analysis.Several factors were related to recurrent wheezing episodes,including risk factors such as maternal smoking during pregnancy (OR =1.47,95％ CI:1.30-1.66),asthma in parents (OR =1.94,95 ％ CI:1.72-2.19),family history of atopy (OR =1.94,95％ CI:1.72-2.19),male (OR =1.42,95 ％ CI:1.19-1.69),history of eczema (OR =2.36,95 ％ CI:1.69-3.30),colds (＞ 6 times) (OR =2.02,95 ％ CI:1.54-2.64),history of bronchopneumonia (OR =1.85,95 ％ CI:1.46-2.34),exposure to cigarette smoking(OR =2.30,95％ CI:1.68-3.14),daycare attendance(OR =2.27,95％ CI:1.97-2.60);Education received by the mother ＞ 12 years (OR =0.80,95％ CI:0.70-0.92) was the protective factor.Conclusions The risk factors of recurrent wheezing(≥3 attacks) in the first 3 years of life are maternal smoking during pregnancy,asthma in parents,family history of atopy,male,history of eczema,colds (＞ 6 times),history of bronchopneumonia,exposure to cigarette smoking and daycare attendance.The protective factor is education received by the mother ≥ 12 years.The prerequisite in precaution of infants recurrent wheezing is to ensure the utmost avoidance of hazardous factors and reinforcement of protective factors.

Objective To study the influences of fenofibrate on oxidative stress and endoplasmic reticulum stress in livers of hyperlipidemic rats. Methods Male SD rats were fed with high-fat diet for 12 weeks to induce a model of hyperlipidemia, then divided into control group, high-fat diet group with another four-week high-fat diet and fenofibrate group, in which rats were treated with fenofibrate [100 mg / (kg·d)] for 4 weeks. Then improvement of insulin resistance was detected in rats with GTT and ITT experiment. The serum levels of glucose (GLU), fasting insulin (FINS),triglyceride (TG) and total cholesterol (TC) were detected. The pathological changes of livers were detected with Oil Red O staining. The oxidative stress indices such as T-SOD, Mn-SOD, GSH and T-AOC were detected with liver homogenate. The expression of GRP78 was detected with real-time quantification RT-PCR and Western blot analysis respectively. Results Compared with rats with high-fat-diet, rats after fenofibrate treatment showed obviously improved insulin resistance, lower serum level of TG, TC and FINS (P < 0.05), decreased number and size of lipid droplets in liver tissue sections. T-SOD level in liver homogenate was significantly increased (P < 0.05), while GSH and T-AOC levels increased but had no obvious differences when compared with control group (P > 0.05). The expression of GRP78 at mRNA and protein levels were increased significantly after fenofibrate treatment (P < 0.05). Conclusions Fenofibrate has significant effects on improving insulin resistance and lipid regulation, which might be related to decreased oxidative stress and subsequent endoplasmic reticulum stress.
