The clinical study of solute removal index(SRI) as an index to quantitate the adequcacy of hemodialysis

The clinical study of solute removal index (SRI) was performed in 20 stable maintenance hemodialysis patients in order to find a proper hemodialydsis dosage and improve the life quality of the patients.Plasma BUN levels were tested pre-hemodialysis and 0, 1 hr post-hemodialysis. Urea generation rate (G)、protein catabolic rate(PCR)、solute removal amount(R)、SRI were calculated by double pools urea kinetic model . The result showed that urea rebound rate was 18.5±3.35 % 1 hr after hemodialysis,R was 13.82±5.48 g, G was 4.85±1.39 g, PCR was 0.94±0.29 g/kg.d, SRI was 71.33±6.8% respectively, which indicated that SRI was a better index to quantitate the adequacy of hemodialysis.

THE STUDY OF DIFFERENCE OF PCNA LABELLED CELL INDEXES BETWEEN ENDOMETRIA OF HUMAN AND MOUSE

40 human endometrial tissues of benign diseases were diviided into 8 groups (phases),and 50 BDF1 mousy endometrial tissues were divided into 5 groups (phases).Immunohistochenical staining was performed to show the PCNA (proliferating cell nuclear antigen)positive cell .In human ,the results suggested that the PCNA layer(48%)of mid-proliferative hpase.The PCNA labelled index was low in superficial epithelium.But in mouse, the results suggested that the Pcna labelled index was the highest(22%)in endometrium of estrus and the labelled cells were distributed mainly in superficial epithelium (60%).The results suggested that times that times and positions of cellular proliferation in endometrial tissues of human and mouse differed greatly.

Prevalence and Correlates of Elevated Blood Pressure in Chinese Children Aged 6-13 Years: a Nationwide School-Based Survey

Objective To estimate the prevalence of elevated blood pressure（EBP） in Chinese children and identify individual and family factors associated with EBP. Methods A nationwide cross-sectional study was conducted in 2010 using stratified cluster sampling. Participants＇ blood pressure was measured, and their parents completed a questionnaire on personal and family characteristics. Prevalence and correlates of EBP were assessed. Results Among a total of 24,333 participants, 20.2% of boys and 16.3% of girls had EBP. The prevalence of EBP increased with the ascending trend of waist circumference, Waist-to-height ratio, and body mass index. The adjusted prevalence ratios（aP Rs） for obese boys and girls were 2.50 and 2.97, respectively. Fewer urban boys（16.2%） had EBP than rural boys（21.7%）. Boys with a family history of hypertension were 12% more likely to have EBP. Children whose mothers received a college education tended to have lower likelihood of EBP; with an aP R was 0.85 among boys and 0.78 among girls. Conclusion EBP is common among obese students and those who have a family history of hypertension. A negative association between mothers＇ education levels and EBP risk in children was found.

Estimation of the Hemodynamic Response during Motor Imagery Using Bayesian RBF Neural Network

Hemodynamic response during motor imagery （MI） is studied extensively by functional magnetic resonance imaging （fMRI） technologies. To further understand the human brain functions under MI, a more precise classification of the brain regions corresponding to each brain function is desired. In this study, a Bayesian trained radial basis function （RBF） neural network, which determines the weights and regularization parameters automatically by Bayesian learning, is applied to make a precise classification of the hemodynamic response to the tasks during the MI experiment. To illustrate the proposed method, data with MI task performance from 1 subject was used. The results demonstrate that this approach splits the hemodynamic response to different tasks successfully.

Study on the Consistency between Production or CostFunction and Index Number

This paper introduces some index concepts used in the study of economical theoryand summarizes some conclusions on the consistency between linear homogeneous production (or cost)function and index formula. In the last section , the authors show the consistency between nonlinearhomogeneous production and index formula and fill the gap in this field.

A primary study on TRISS in a Chinese hospital

Objective: To investigate a revision of the Trauma and Injury Severity Score (TRISS) weight coefficients in order to overcome the inference from foreign coefficients on Chinese trauma scoring. Methods: The data of 1 297 Chinese trauma patients were studied for trauma scoring with the Revised Trauma Score Injury Severity Score TRISS (RTS ISS TRISS) system to get a serial of new weight coefficients through analyzing a multivariation logical regression between the outcome and the injury severity. Results: ISS was higher but the Age Score and probability of survival (Ps) of the death group were lower than those of the survival group. New values of RTS ISS Age coefficients differed from the Major Trauma Outcome Study (MTOS) ones, through which the constant b 0 decreased its negative value, and ISS weight b 2 increased its negative value, but RTS weight b 1 and age weight b 3 changed with the trauma types. MTOSs values and new values of weight coefficients were used on 1 297 patients for prognosis by calculating Ps. The accuracy of new values ( 90.13 %) was a little higher than that of MTOSs (89.5%), with a promotion in specialization but a loss in sensitivity. Conclusions: A revision of TRISSs weight coefficients is either necessary or feasible. To achieve this purpose, a Chinese trauma database with large capacity is recommended.
