Objective This paper sums up professor Zhang Peiying's clinical experience in diagnosing and treating unstable angina(UA) of coronary heart disease. [Methods]Generalizing the pathogenesis, rules of treatment and principle of diagnosis about UA, through the reference of classical theory of Traditional Chinese medicine and clinical observation. Then analyse professor Zhang Peiying's characteristics about diagnosing and treating UA by two examples of medical record.[Results]Professor Zhang considers deficiency of Qi and stagnation of phlegm is the premise and foundation of UA, holds that stagnation of phlegm, stagnation of blood and spasm of heart vessel are the key causes of the disease and removing blood stasis, relieving spasm of vessel, strengthening the spleen and reducing phlegm is the basic treatment principle. He divides UA into 4 categories: stagnation of heart blood syndrome, stagnation of phlegm and blood syndrome, deficiency of Qi and stagnation of blood syndrome,weakness of Yang with stagnation of phlegm and blood. [Conclusions]Professor Zhang Peiying's scholar thought and clinical experience in diagnosing and treating UA of coronary heart disease is effective. His thought and clinical experience are worth extending and applying.

Objective To investigate the levels of cytokines in sera of patients with various types of psoriasis.Methods Six cytokines, sIL-2R、 IL-2、 -4、 -10、 -12 and IFN-γ , were detected by sandwich ELISA in the sera from 15 patients with guttate psoriasis, 23 plaque psoriasis, 9 pustular psoriasis, 9 arthropathic psoriasis and 9 erythrodermic psoriasis.Results Significantly higher levels of cytokines were observed in guttate psoriasis for sIL-2R (P<0.01), in plaque psoriasis for IL-4,-12 and sIL-2R (P< 0.05 or < 0.01), in pustular psoriasis for IL-4 and -10 (P< 0.05), in arthropathic psoriasis for IL-10 (P< 0.01), in comparison with the controls.The levels of the six cytokines were increased in erythrodermic psoriasis with no significant difference from the controls.The ratio of the average level of IL-4 to IFN-γ was 1.57 in pustular psoriasis, 0.61 in plaque psoriasis, 0.30 in gutatte psoriasis, 0.24 in erythrodermic psoriasis, and 0.02 in arthropathic psoriasis.Conclusion There is different expression of cytokines in sera of patients with various types of psoriasis.

The complex multidimensional visual patterns of facial expression is particularly well sui ted for studying perception and the processes underlying perceptual integration of component parts into a meaningful whole.With the high resolution in milliseconds,event-related potential (ERP) may be an excellent technique to track the time course of cognitive processing for facial emotions.Facial affective stimuli elicit particular ERP components involved in early processing of facial expressions,including:early sensory processing of visual stimuli:the P100;early structural encoding of facial features:the N170;second-order sustained activities necessary for consequent deeper processing:the posterior P2 and decoding of facial features to identify emotional content:the N250.We reviewed above mentioned ERP components respectively,in order to add the knowledge about ERP components as indicators of neural dynamics of facial emotion processing,and to provide a point of reference for further exploration on facial emotion processing that may be useful for understanding human cognition development and pathology.

Objective To evaluate the fetal cardiovascular function in selective intrauterine growth restriction (sIUGR)in monochorionic diamniotic(MCDA)twins by using 2D and color Doppler ultrasonography. Methods Twenty - four sIUGR pregnancies and 20 normal MCDA twins pregnancies were enrolled at the First Affiliated Hospital of Sun Yat - Sen University from December 2013 to September 2014,and cardiac structure of fetus and Doppler patterns of the umbilical artery(UA),umbilical vein(UV),pulsatility index of ductus venosus(DV - PI),atrioventricular valve, semilunar valve,tricuspid annulus systolic displacement(TAPSE),fractional shortening of left ventricle short axis(FS) and myocardial performance index(Tei index)of both ventricles were assessed. Results Cardiothoracic ratio,heart rate,DV - PI,FS,TAPSE,Tei index of the left ventricle(0. 34 ± 0. 03,0. 34 ± 0. 04),Tei index of the right ventricle (0. 35 ± 0. 03,0. 35 ± 0. 03)were not significantly different compared with those of the normal MCDA twins(all P ﹥0. 05). Cardiothoracic ratio,ventricular wall thickness,isovolumetric relaxation time( IRT),isovolumetric contraction time(ICT),TAPSE and tricuspid regurgitation(TR)in the larger twins of sIUGR were significantly bigger than those in the smaller twins of sIUGR(all P ﹤ 0. 05),Tei index of both ventricles in the larger twin of sIUGR was significantly higher than that in the smaller twins of sIUGR(Tei index of left ventricle:0. 43 ± 0. 06 vs 0. 35 ± 0. 04,Tei index of right ventricle:0. 43 ± 0. 06 vs 0. 34 ± 0. 04,P ﹤ 0. 05),the peak E in early diastolic / the peak A in atrial contraction (E/ A),the percentage of inflow during of cardiac cycle length(inflow/ CCL)in larger twin of sIUGR were significantly lower than those in smaller twin of sIUGR(all P ﹤ 0. 05). Conclusions There was no difference of cardiac function in normal MCDA twins,at the beginning of the diagnosis of sIUGR,cardiac dysfunction were found in larger twin,follow -up examination are helpful to clinical decision.

Objective To investigate the charactoristics of comprehension of words or phrases of nouns in chidren with autism. Meth-ods From November, 2014 to April, 2015, 43 children with autism and 10 with Down's syndrome aged 7-14 years accepting special educa-tion, and other 42 normal children aged 7-8 years were asked to identify the pictures according to the words, wearing Tobii Ⅱ Glasses to re-cord eyes movement. Results The incidence of right answer was more in the normal children than in the ones with autism or Down's syn-drome (χ2>5.647, P<0.05), and more focused on the right pictures (χ2>6.248, P<0.05). For the phrases, the children with autism tended to fo-cus on the words as the order of speech, but not the center word (χ2>7.15, P<0.05). For the words, the first views after questions were differ-ent from the children with autism to the normal children (χ2>5.04, P<0.05). Conclusion Children with autism tend to focus on the words as the order of speech, but not the center word, which may influence the phrases understanding, and be influenced by the intuitive vision.
