Computer-administered neurobehavioral evaluation system (NES)was developed based on the neurobehavioral core test battery (NCTB)recommended by WHO/NIOSH in 1985. Compared with NCTB,the reliability and validity of NES was much improved and some disadvantages of NCTB were made up in NES. This article reviewed the history of NES development,its application in the evaluation of children's neurobehavioral functions and its defects. The studies suggested that some items of NES test,such as finger tapping,continuous performance test and hand-eye coordination,could be used to evaluate earlier damage induced by chemicals on neurobehavioral functions of children.

This article was aimed to explore the intelligent integration of database as the core-data and application of data mining as the core of knowledge discovery. On the basis of the existed set of information-sharing platform, this article elaborated from aspects of formatting HER intelligent integration, data integration and multi-method combined data mining intelligent integration. With the demonstration study on syndrome distribution and syndrome diagnostic criteria of acute exacerbations of chronic obstructive pulmonary disease (AECOPD), data integration and intelligence optimization of Crystal Reports and complex networks were applied to dig out the correlation between syndromes and symptoms, disease-syndromes-herb association analysis. Analysis mentioned above showed that based on the shared system, and in accordance to research programs, intelligent integration of data and data mining methods, the improvement of the sharing platform application is proved feasible.

Based on the Clinical Medical Research Information Sharing System ( CMRISS ) , this article took thedisease-syndrome-herb study on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) as a model to explore the establishment of disease-syndrome-herb study method on many types of diseases for the guidance of Chinese medicine clinical practice. The CMRISS of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine, which contained 5000 format electronic medical records from August 2011 to March 2013 , was used as the database . Data preprocessing , crystal reports and complex network were used in data mining to receive the frequency relation of AECOPD disease-syndrome-herb in order to analyze medica-tion features of different Chinese medicine clinical syndromes of AECOPD . The results showed that three syn-dromes, which were phlegm-heat obstructing the lungs, phlegm-stasis obstructing the lungs, and qi-yin deficien-cy, have corresponding Chinese herbs of licorice, orange peel and earthworm. The treatment of syndrome of phlegm-heat obstructing the lungs contains herbs to clear heat, remove phlegm and activate blood circulation. The treatment of syndrome of qi-yin deficiency contains herbs to benefitqi , nourish yin as well as to activate blood circulation and remove phlegm. It was concluded that the application of CMRISS is able to process a large amount of clinical data. The data mining results can be used to guide clinical practice. It provided a better plat-form for the scientific research of Chinese medicine clinical practice .

Objective To observe the effect of constraint-induced movement therapy combined with motor imagery on unilateral spatial neglect (USN) in stroke patients. Methods Fifty stroke patients with USN were randomly divided into a treatment group ( n = 27 ) and a control group ( n = 23 ). Both groups received routine physical therapy training, including with the Bobath technique and low frequency electrotherapy, while the treatment group received constraint-induced movement therapy and motor imagery in addition. All the patients were assessed with 4 scales of the regular USN assessment ( cancellation tests, line bisection tests, clock drawing tests,copying drawing tests) and with the Barthel index (BI) before and after 8 weeks of treatment. Results After 8 weeks of treatment, both groups' average USN assessments and Barthel indices improved significantly. Furthermore, both the USN results and the Barthel index scores in the treatment group were, on average, significantly better than those in the control group. Conclusion For USN stroke patients, constraint-induced movement therapy combined with motor imagery improves the symptoms of USN and ADL ability significantly better than routine physical therapy treatment alone.

Objectives:To learn about the attitudes toward the "Global Minimum Essential Requirements(GMER) in medical education" between Chinese doctors and graduates from the same medical university and to offer reference for spreading GMER in China.Methods: To investigate the subbjects using a questionnaire describing the related abilities of GMER.Description,rank test,multivariate analysis of variance and factor analysis are applied in data analysis.Results: In general,there are different attitudes toward GMER between doctors and graduates.13 of 23 items have statistical significance in scores between groups.The proportion of person considering every item as important or very important among doctors is higher than that among graduates.There is statistical significance between groups on the transformed score in 7 domains of GMER.The domain of topmost score is "clinical skills",and of the lowermost one is "community health & health system".Conclusions: Doctors and graduates both accept GMER.They both pay attention to occupational skills,but ignore the public health.Doctors think much of basic knowledge,while graduates are short of the cognition on "Information Management".

Objective: To analyze the trends of development and equity of health institutions in China during the period from 2002 to 2013 , and put forward references to optimize the decision-making on health resources alloca-tion. Methods:Statistical map, Gini coefficient and other methods were used to analyze the distribution and equity of health institutions in China for 12 years, during the period from 2002 to 2013. Results:(1) The overall development of health institutions is on the rise in China, and the distribution density of health resources with the population ad-justment is opposite to the adjustment of both population and geographic area at the same time. (2) In the past 12 years, the number of tertiary hospitals showed an increasing trend, and growth in the eastern region was the most sig-nificant. (3) From 2002 to 2013, the Gini coefficient of the number of health institutions and beds per 1,000 per-sons per square kilometer was maintained at 0. 40, and decreased from 0. 70 to 0. 60 in the eastern region of China, respectively. This same number was maintained at 0. 40 and 0. 20 in the central and western region. Conclusion: In China, the fairness trend of health resources allocation has improved during the period from 2002 to 2013, but the imbalance is more serious in the eastern region than in the central and western regions. It should be paid more atten-tion to optimizing the health resources allocation according to the local conditions of different regions, especially the influence of geographical distribution.

Objective To observe vasculogenic mimicry formation difference in human hepatocellular carcinoma cell lines MHCC97-H/L with different metastatic potentials under three-dimensional culture condition,and to study extracellular matrix and adhesion molecules-related mechanism of vasculogenic mimicry.Methods Three-dimensional cell culture system of MHCC97-H/L was established to observe tubelike structures by inverted microscope.Human umbilical vein endothelial cell(HUVEC),human hepatocellular carcinoma cell line Hep3B with non-metastatic potentials and normal human hepatic cell line HL-7702 were taken as control.Gene expression profiles of MHCC97-H and MHCC97-L were detected by Oligo extracellular matrix and adhesion molecules microarray analysis.Two differentially expressed genes were verified with semi-quantitative reverse transcriptionpolymerase chain reaction(RT-PCR)and Western blot.All data were analyzed using two sample t test.Results After a 24-hour three-dimensional culture,the length of tubelike structures was(474 ± 16)mm/cm2 in MHCC97-H,which were significantly longer than(320 ±41)mm/cm2 in MHCC97-L(t =6.119,P ＜0.05).Hep3B and HL-7702 could not form tubelike structures.Compared with MHCC97-L,the expression of 7 genes were up-regulated and the expression of 3 genes were down-regulated among a total of 113 angiogenesis genes in MHCC97-H.Two of the genes with differential expressions including tenascin C and extracellular matrix protein 1 were further validated by RT-PCR and Western blot.Conclusion MHCC97-H has stronger ability to form vasculogenic mimicry than MHCC97-L,and this perhaps correlates with the differential expression of certain extracellular matrix and adhesion molecules-related genes in MHCC97-H.

Background and purpose: Pancreatic intraepithelial neoplasia (PanIN) may be a precursor lesion of inifltrating pancreatic ductal adenocarcinoma. The mutation of the phenotypic impact of K-ras G12D alone, silencing of p53 and p16 could promote this process. The role of Smad4 in this progression was poorly understood. In our previous studies, we investigated that RNA interference silence of Smad4 to promote the PanIN cell malignant transformation. In the present study, we investigate. The further explores the siRNA interference of Smad4 expression on PanIN cells could lead to proliferation and metastasis in vitro and in vivo. Methods:Smad4 knock-down PanIN cells (PanIN-S) were established by stable transfection with lentiviral-mediated Smad4 RNA interference. In vitro,silence of Smad4 enhanced the proliferation of PanIN cells as determined by cell counting. A soft agar assay was used to assess the anchorage-independent growth ability of cells. Cell migration and invasion assays were performed using transwell chambers with or without Matrigel. In xenograft model experiments, PCNA, VEGF and MMP-9 staining was separately used to evaluate cell proliferation and angiogenesis and migration (VEGF and MMP-9). Results:Effect of siRNA of Smad4 gene in PanIN cells was conifrmed by real-time RT-PCR and western blot. In vitro, silence of Smad4 enhanced the proliferation of PanIN cells as determined by cell counting. Soft agar assay showed that there were more colony cell numbers in PanIN-S cells compared with PanIN cells (P<0.05). Using the transwell assay, we observed that PanIN-S cells migrated faster than PanIN cells and similar results were obtained by Matrigel assay (P<0.05). Furthermore, immunohistochemical analysis of the harvested tumors suggested that Smad4 silencing was associated with cell proliferation (PCNA reactivity) and angiogenesis and migration (VEGF and MMP-9), and the expressions of PCNA, VEGF and MMP-9 in PanIN-S group were signiifcantly increased (P<0.05). Conclusion:Silence of Smad4 in PanIN cells enhanced progression to invasive adenocarcinoma of the pancreas by promoting cell growth, migration and invasion. Smad4 might be a new diagnostic marker in pancreatic cancer and prove to be a feasible and novel target for therapeutic intervention.

This study was aimed to analyze correlation between traditional Chinese medicine (TCM) syndromes and symptoms of acute exacerbation chronic obstructive pulmonary disease (AECOPD) based on complex network in order to provide a scientific basis for TCM syndrome amendments of diagnostic criteria, and explore relevant technologies to promote its application. By way of the current Clinical Research Information Sharing System, data and data pro-cessing were carried out (EHR 3000 between August 2011 and January 2013) into the database by ETL software. The MISCR (correlation between common symptoms and common syndromes) from both common symptoms and com-mon syndromes of AECOPD was analyzed with existing diagnosis standards of AECOPD. The comparative analysis on TCM syndromes such as heat phlegm obstructing the lung, lung and kidney qi deficiency, phlegm turbid obstructing the lung and their correspondent existing diagnosis standards of AECOPD showed that the common TCM syndromes in the clinic are the mixture of deficiency and excess syndromes. However, some individual symptom is contradicted to its correspondent syndrome. It was concluded that based on the Clinical Research Information Sharing System, the research on correlation analysis between syndromes and symptoms of AECOPD can provide strong evidence and methodology for the validation and revision of TCM diagnostic criteria.
