Objective To investigate the clinical value of the optical microscope on the quality control of the coagulation specimen microscopic examination before the coagulation test.Methods 92 patients with coagulation specimens agglutination occurs which taken were selected as the experimental group,92 patients re-blood microscopy to ensure that no agglutination phenomenon was set to control,observed differences in coagulation indexes of the two groups.Results The PT,APTT,TT and Fg were statistically significant(P ＜ 0.05) between experimental group and control group by the q test.Different agglutination specimens group in the experimental group by analysis of variance,PT,APTT.TT and Fg were statistically significant(P ＜ 0.05) between groups comparison of the q test analysis,PT,APTT,TT and Fg were significant differences (P ＜ 0.05).With the aggravation of blood specimens agglutination,PT,APTT and TT time extension and Fg concentration reduce more serious.Conclusion Optical microscope before the introduction of clotting function tests experimental quality control a large extent,to enhance the accuracy of laboratory coagulation test results,clinical diagnosis and preoperative preparation has important clinical value.

Serious and/or continuous cerebral hemodynamics disorder is the main cause of neonatal brain injury.Monitoring its changes by using simple,accurate and effective techniques has guiding significances in maintaining the stability of neonatal cerebral hemodynamics.This paper aims to introduce several cerebral hemodynamic monitoring techniques,including color Doppler ultrasound,near infrared spectroscopy,noninvasive magnetic resonance imaging,and provide references to the clinical application in neonatal field.

Neurofeedback as a behavior therapy measurement for ADHD has gained increasing attention in recent years.Based on researches have been published of neurofeedback in ADHD in nearly 5 years,the researches development of neurofeedback are reviewed.The data showed that TBR,SMR and SCP neurofeedback are clinically effective treatment for ADHD.Future controlled clinical trials should focus on such known protocols for specific research,and be designed in line with learning theory.

Objective To explore the effect of protocatechuic acid on serum tumor necrosis factor-α( TNF-α) , interleukin-1β( IL-1β) and oxidative stress products levels in Parkinson rats.Methods 60 male SD rats were randomly divided into normal control group ( n=10 ) , model group (n=10), madopar group (n=20) and protocatechuic acid group (n=20).Rat model with Parkinson disease were builded in model group, madopar group and protocatechuic acid group.Madopar group and protocatechuic acid group were given corresponding drug with a consecutive treatment of two weeks.After treatment,the serum TNF-α,malondialdehyde (MDA), superoxide dismutase (SOD) and IL-1βlevels were detected in all groups.Results Compared with normal control group, the serum TNF-α, IL-1βand MDA levels in model group were significantly higher, and SOD level was lower (P<0.05).Compared with model group, the serum TNF-α, IL-1βand MDA levels in madopar group pre-treatment were significantly lower, and SOD level was higher (P<0.05).There were no significant difference of serum TNF-α, IL-1β, MDA and SOD levels between madopar group and protocatechuic acid group.Conclusion The protocatechuic acid could significantly reduce the serum TNF-α, MDA and IL-1βlevels in Parkinson model rats, enhance the activity of SOD, which has protective effect on oxidative stress injury induced by Parkinson disease.

Objective:To review the research hotspots and evolution of electroencephalogram (EEG) biofeedback in attention-deficit/hyperactivity disorder (ADHD) by knowledge mapping software.Methods:Based on web of science core collection database,we searched the literature with keywords (EEG biofeedback OR neurofeedback) AND (ADHD OR attention-deficit/hyperactivity disorder) in topic and time limit set before December 31,2015.319 literature were accepted,using the CiteSpace to depict the hot keywords,cited references and countries.Results:United States of America,Germany,Netherlands were top 3 countries in publishing papers of EEG biofeedback in ADHD.Based on burst of cited references,the research evolution of EEG biofeedback in ADHD could be divided into three stages.The hotspots of EEG biofeedback in ADHD were Slow Cortical Potentials protocol and double-blind placebo-controlled study.Conclusion:Future research should focus on the mechanism of EEG biofeedback and such known protocols for individualized treatment,or be designed along the lines of learning theory.

OBJECTIVE: To explore the olfactory abilities in patients with allergic rhinitis (AR), analyze the correlation between olfactory bulb (OB) volume with depth of olfactory sulcus (OS) and olfactory function in patients with AR. METHOD: One hundred patients with AR were compared with one hundred controls in terms of olfactory function T&T testing, OB volume and depth of OS assessed with magnetic resonance imaging (MRI). T&T testing and MRI were done after a year in 100 AR patients,the results were compared with the initial results. RESULT: The OB volume in AR patients was (29.53±3.95) mm3 on the left, (29.67±14.21)mm3 on the right, (29.61±4.05) mm3 on average; The OB volume in controls was (48.93±6.73)mm3 on the left side, (48.81±7.43)mm3 on the right side, (48.85±7.11)mm3 on average; The OB volume in AR patients was less then the control group(t= 6.321, 6.141, 6.221, P<0.01). The OS depth had no statistical difference between AR patients and controls (t=1.032, 0.972, 0.991, P>0.05). Olfactory discriminate threshold was negatively correlated with OB volume in AR patients (r=-0.46, P<0.05); and it was no correlated with depth of OS (r=-0.012,P>0.05). Among 100 followed-up AR patients, 43 showed increased in OB volume and olfactory function after a year, but there was no statistical difference (t= 0. 811,0. 843, 0.826, P>0.05; Z=1.911, P>0.05) ,and the other 57 showed no significant changes of OB volume and olfactory function. CONCLUSION In AR patients, the OB volume and olfactory function decreased, but the depth of OS had no significant changes. The OB volume is correlated with olfactory function, while the depth of OS is no correlated with olfactory function. Conservative treatment had some clinical significance on the recovery of olfactory function in patients with AR.

OSCE is an examination of objective evaluation of the clinical skills.This article introduced the development of OSCE at home and aboard,and compared the difference of the exam setting in America,England,Canada and China Medical University.The advantages and disadvantages of SP in OSCE were also analyzed.It was discussed that OSCE would be widely applied in China.

Five-zang is the nucleus of viscera state doctrine. The nonequilibrium of Five-zang's different properties guides syndrome differentiation and treatment in TCM. This article discusses five-zang's nonequilibrium from lung being a delicate viscus,correlation between lung and five-zang,physiology and pathology of lung and so on. It attaches the importance to five-zang's nonequilibrium and clinical level of syndrome differentiation.

Direct Digital Frequency Synthesis(DDS) technology is realized on complex programmable logical component(CPLD) with hardware description language.SCM controls CPLD by the input/output port through the procedure so as to produce the profile signal for power module.Then the high pressure shielding system controls the power module so as to drive the output transformer for the high frequency high-pressure output of high frequency electricity knife.This system has such characteristics as good frequency stability,revision convenience and so on.The CPLD hard wire logic is described through Verilog HDL,and the monolithic integrated circuit firmware is compiled through Keil C51.This article carries on the detailed elaboration for software and hardware design through the code example and the principle schematic drawing.
