Objective:To explore differences in beha viors and quality of life between asthmatic and non-asthmatic children . Methods:Be haviors and quality of life were assessed in the 84 children with asthma and healthy children,4-11 years of age .Results :Behavioral problems were more prevalent in asthmatics than non-asthmatics.The major beha vior al problems in children with asthma were recession, physical complaints,anxiety/ de pression,and social intercourse.The children with asthma were less satisfact ory than healthy children with respect to quality of life especially on anxiety,depressi on and somatic feelings.Conclusion:Asthma contribut es to the developmen t of behavioral problem and adversely affects the children's quality of life.

Objective To observe the clinical efficacy of the early activity on preventing deep vein thrombosis after joint replacement. Methods A total of 90 patients who undergone skeleton and knee joint replacement from January 2014 to January 2015 were randomly divid-ed into the observation group and the control group (with 45 cases in each group)according to the random number table method.The control group were given routine nursing care to prevent thrombosis,while the observation group were given intervention nursing,namely implementa-tion of early activities.The related symptoms of deep venous thrombosis and D-dimer level of high blood coagulation state of plasma of the two groups were observed and compared before and after treatment.Results The symptoms of deep vein thrombosis of the observation group in the early postoperative period were less than that of the control group,and the difference was significant(P <0.05).The D-dimer level of the observation group was lower than that of the control group 7 days after the operation with a significant difference (P <0.05).Conclusion Systematic nursing intervention of early activities can significantly reduce the related symptoms of forming deep vein thrombosis after joint re-placement.In addition,it has an apparent effect on lowing the high blood coagulation state and preventing deep vein thrombosis.

Objective To propose an extraction algorithm for extraction of breast tumor boundary in its ultrasonic image. Methods A novel Global-Local Energy function was proposed in the variational Level Set formulation for the curve evolution. By enhancing the intensity of local information, the breast tumor boundary was obtained from ultrasonic images accurately. Results Experiments on a synthetic ultrasound image showed that this method was more accurate at segmenting the object from the background than the Chan-Vese algorithm based on the global optimization. Experiments on 103 ultrasonic breast tumor images also showed that the boundaries were extracted accurately with this method without any pre-processing step. Conclusion This proposed method is expected for the fast and accurate boundary extraction of ultrasonic breast tumor boundary from ultrasonic image.

Objective:To compare the time domain and the frequency domain of speech-evoked auditory brainstem response measured by stimulation of left and right ears, and to explore the difference and possible reasons of neural coding for speech from different ears in auditory brainstem.Method:Speech-ABRs to syllable /da/ of 31 healthy adults were recorded. Statistical analysis was performed on time-domain parameters, such as latencies and amplitudes of featured peaks, and frequency-domain ones, such as amplitudes of the fundamental frequency and the first formant of speech-ABRs ranging from 20-50 ms. A scoring criterion to grade the appearance of featured waves was proposed for waveform evaluation.Result:There were no significant difference for the latencies of binaural featured peaks and amplitudes of feature peaks(except peaks A and O). The waveform scores of right ear were greater than that of left ear. The amplitudes of fundamental frequency of binaural waves were both greater than that of the first formant. There was no significant difference of amplitudes of fundamental frequency and the first formant between two ears.Conclusion:The origins and distributions of speech-ABR are essentially symmetrical in brainstem in contrast with the hemisphere asymmetry of speech.

ABSTRACT:Objective To evaluate the clinical therapeutic effect and safety of tumor necrosis factor alpha (TNF-α)blockers in treating moderately to severely active ulcerative colitis (UC)by meta-analysis.Methods Such databases as the Cochrane Central Register of Controlled Trials,PubMed,OVID,Embase,ISI,CBM,CNKI, VIP,and WanFang Data were searched from establishment to June 2013.All randomized clinical trials (RCTs)on tumor necrosis factor alpha blockers in treating UC were collected,and then selected on the basis of the inclusion and exclusion criteria.We assessed the methodological quality,extracted the data from the included articles and performed the meta-analysis with Revman 5.1.Results A total of 13 RCTs involving 3334 patients were analyzed.TNF-αblockers group was superior to the control group in the short-term clinical response (OR =2.5 1, 95% CI 1.73,3.64),short-term clinical remission (OR =2.74,95% CI 1.80,4.1 6),long-term clinical response (OR =2.98,95% CI 1.98,4.47),1ong-term clinical remission (OR =2.64,95% CI 1.89,3.67),and mucosal healing (OR =1.89,95% CI 1.39,2.59)compared with control group.TNF-αblockers could also reduce the rate of colectomy (OR =0.61,95% CI 0.41,0.89)and improve inflammatory bowel disease questionnaire scores (MD=14.74,95% CI 1 1.43,18.06 ).There was no significant difference between the two groups in all reported adverse effects (OR =1.14,95% CI 0.97,1.34)and serious adverse effects (OR=0.78,95% CI 0.56,1.09).Conclusion Compared with conventional therapy or placebo,TNF-αblocking agents can improve the therapeutics effect on UC in clinical response,clinical remission and mucosal healing,and also can reduce the rate of colectomy. In patients with moderately to severely active UC treated with TNF-α blocking agents,it is easier to achieve the improvement of life quality.TNF-αblocking agents treatment is safe for UC.This conclusion should be verified with more large-scale and high-quality RCTs.

Objective:To investigate the speech-evoked brainstem response (speech-ABR) of normal young people under different recording periods,which can provide the experimental evidences for researches on the stability of speech-ABR and promote its applications in clinical researches.Methods:40 healthy young people were randomly divided into two groups,which were tested following the same protocol at different time of two months interval.Latencies and amplitudes of the feature peaks in these groups were compared and the rates of appearance (detection rate) of the feature peaks were analyzed statistically.Results:Speech-ABRs were recorded successfully in two groups.The latencies and amplitudes of feature peaks in these groups were not different statistically,and the detection rates of V,A,C and F peaks were higher than others.Conclusion:The speech-ABRs of the two groups are stable,and the V,A,C and F peaks can be used as important indicators of clinical observation,showing that Speech-ABR is a promising tool in the study of Speech perception mechanism.

OBJECTIVE To explore the latency characteristics of speech evoked auditory brainstem response(speech-ABR)from healthy Chinese adults by different stimulation intensities and its significance in neural encoding of speech in the brainstem. METHODS ABRs to speech syllables of 32 subjects were recorded in four stimulus intensities varied from 20 to 80 dB SPL by 20 dB steps, under 11.1/s stimulus rate. A set of featured waves were determined under these intensities, and then the characteristics of their latencies were analyzed. RESULTS A series of featured waves were observed starting from onset response(including V and A waves), transitional C wave, then following frequency-following responses(FFRs), and the offset O wave. As the reduction of stimulus intensity, the latencies of speech-ABR delayed significantly(P

qualitative and quantitative analysis of solid depolymerization products for supercritical methanolysis of ploy(ethylene terephthalate) polyester (PET) were studied by means of reversedphase high performance liquid chromatogr aphy on ZorbaxC8(4.6mm×250mm) with 70%(V/V) methanol as mobile phase. The results showed that the solid depolymerization products were mainly composed of dimethyl terephthalate (DMT), methyl(2hydroxyethyl)terephthalate (MHET), bis(hydroxyethyl)tere phthalate (BHET), dimers and oligomers, which could be separated effectively under the above chromatographic conditions. The calibration curves of DMT and BHET were linear in the range of 1.0～45 mg/L (n=8),r=0.9998～1.0000 and RSD＜2.8%. The determination limits of DMT and BHET were 4.0×10-4μg and 6.0×10-4μg respectively. 
