ObjectiveTo assess the value of the Beijing version of Montreal Cognitive Assessment ( MoCA) in community dwelling older adults residing in Shenyang,China.MethodsThe stratified random sampling method was used to investigate the population over 60 years old in 4 communities of Shenyang in the year 2011.Mini-Mental State Examination (MMSE) and the Beijing version of MoCA were administered to all participants.258 old people finished the assessment.ResultsThe internal consistency of the MoCA Beijing version was good,yielding a Cronbach alpha of 0.836.The correlation between the MoCA Beijing version and the MMSE was good(r=0.623,P＜0.001 ).Only 15.1％ participants had an education of over 12 years,but 26.3％ participants had an education of 6 years or less.Only 3 items of MoCA Beijing version ( naming lion,forward digit span,recall daisy)showednosignificantdifferencebetweenpersonswithandwithoutover 6yearsofeducation.ConclusionsThe results indicates that the Beijing version of MoCA have good reliability and validity.This study shows that an education of 6 years or less might be the proper population to add the one point in China,and the cutoff-point of 26 for normal is too high for Chinese population.

In this cross-sectional study, consecutive Chinese Han ethnic inpatients in the Division of Cardiology, the First Affiliated Hospital of Soochow University from January 1, 2010 to December 31, 2013 were included. According to the exclusion criteria, 9 587 patients [1 604 with type 2 diabetes mellitus (T2DM) and 7 983 without T2DM]were obtained for final analysis. Logistic regression model was used to analyze the association of ApoB/A-1 ratio with T2DM and the possible interactions between ApoB/A-1 ratio and other risk factors. The results showed that the distribution of ApoB/A-1 ratio was positively skewed in Chinese Han ethic population. The median of ApoB/A-1 ratio of female was lower than that of male (0.68 vs 0.73,P<0.01). In all groups, the proportion of T2DM was increased with the raised ApoB/A-1 ratio. By the stratification analyses of sex, age, coronary artery disease, and the use of statins, ApoB/A-1 ratio was still correlated with T2DM. There existed significant interactions between ApoB/A-1 ratio and the smoking status or creatinine in T2DM.

Targeting the common fact that colleges and universities of traditional Chinese medicine neglect management post practice,are lack of cutting-edge,cross-disciplinary and methodological courses,fail to reflect the traditional Chinese medicine's singularity and update courses slowly during the process of cultivating their graduate students,Heilongjiang University of Chinese Medicine innovates its culture system of graduate student in related major.It is also devoted to developing problem-based learning,introducing bitutor system,reforming course system,which may hopefully improve their graduate students' innovative thoughts and abilities,strengthen their innovative knowledge theory system to finally discover an appropriate reform model for the culture system which can be perfectly replicable.

Objective To explore the value of virtual touch tissue imaging (VTI) of acoustic radiation force impulse (ARFI) elastography in the differential diagnosis of benign and malignant thyroid nodules.Methods VTI features of 77 histologically proven thyroid nodules in 74 patients were analyzed and the VTI features were divided into 6 grades.The higher grade represented higher tissue stiffness.Differences in VTI grade between benign and malignant lesions were analyzed by receiver operator characteristic (ROC) curve,and the sensitivity,specificity and accuracy were calculated.Results 77 pathologically proven thyroid nodules included 61 benign and 16 malignant lesions.VTI images classification included 0 in grade Ⅰ,1 ingrade Ⅱ,1 in grade Ⅲ,9 in grade Ⅳ,3 in grade Ⅴ and 2 in grade Ⅵ for malignant diseases ; and included 18 in grade Ⅰ,28 in grade Ⅱ,10 in grade Ⅲ,1 in grade Ⅳ,2 in grade Ⅴ and 2 in grade Ⅵ for benign diseases.The best diagnostic point of VTI-grade was grade Ⅳ.When VTI-grade Ⅳ or greater was used as the diagnostic criterium for malignancy,the sensitivity,specificity and accuracy rate in differentiation between benign and malignant thyroid nodules were 87.50％,91.80％ and 90.9(％ respectively.Conclusions VTI is useful in the differential diagnosis between benign and malignant thyroid nodules.

Objective:To investigate the expression and prognostic significance of CD19 in patients with Acute myelogenous leukemia with AML1-ETO positive. Methods: Clinical data of 66 patients AML with AML1-ETO positive who were newly diagnosed from Jan 2010 to Dec 2015 were collected. To retrospectively analyze the relationship between clinical characteristics and expression of CD19,so dose the prognosis. Results:The positive rate of CD19 expressing in AML with AML1-ETO positive was 50. 0%. There were no statistically significant differences in terms of age,gender,hemoglobin,platelet,percentage of bone marrow blasts,accompanied with chromosome ,gene mutations between patients with and without CD19 expression(P>0. 05). The white blood cell count(WBC) of the CD19 negative group was higher than CD19 positive group,while showed significant difference(P=0. 027). Although the relapse-free survival (RFS) of patients with CD19 expression was higher than those without,no significant difference was calculated (P=0. 105). Patients with CD19 expression had superior overall survival ( OS ) compared to those without CD19 expression ( P = 0. 030 ) . Multivariable analysis for OS identified CD19 positivity as an independent predictor associated with better prognosis. Conclusion: The expression of CD19 in AML with AML1-ETO positive may be an indicator associated with better prognosis.

AIM To prepare diosgenin nanosuspensions.METHODS The nanosuspensions prepared by media milling method were solidificated by freeze drying method.With particle size and polydispersity index (PDI) as evaluation indices,stabilizer kind,ratio of diosgenin to stabilizer,ratio of preliminary nanosuspension volume to grinding bead amount,milling time,lyoprotectant kind and its amount as influencing factors,single factor test was applied to screening preparation and solidification processes.The morphology of nanosuspensions was observed,then the particle sizes and polydispersity indices of nanosuspensions and freeze-dried powder were determined.RESULTS The optimal conditions were determined to be 6:1 for ratio of diosgenin to Pluronic F127 (stabilizer Ⅰ),50:1 for ratio of diogenin to sodium dodecyl sulfate (SDS,stabilizer Ⅱ),1:4 for ratio of preliminary nanosuspension volume to grinding bead amount,120 min for milling time,and 8％ PEG-6000 and 2％ mannitol as lyoprotectants.The average particle size and polydispersity index of rod-like or flaky nanosuspensions were (348.1 ±14.2) nm and 0.244 ± 0.059,respectively,which were lower than those of freeze-dried powder.At room temperature,the particle sizes of nanosuspensions and freeze-dried powder remained stable within 35 d and 3 months,respectively.CONCLUSION The physical stability of diosgenin freeze-dried powder is superior to that of its nanosuspensions,which can be used after being reconstituted.

Objective To explore the influence of continuous veno-venous hemofiltration (CVVH) therapy on cardiac index (CD, global end-diastolic volume index (GEDI) and extravascular lung water index (ELWI) monitored by Pulse-indicated continuous cardiac output (PiCCO). Methods The 12 critically ill patients with acute renal failure were selected consecutively from department of intensive care unit (ICU) in Beijing Hospital. The patients who received CVVH therapy were monitored by PiCCO plus device. The hemodynamic measurements were performed during the process and interruption of CVVH. Pared t-test was used to analyze the values of CI, GEDI and ELWI. Results A total of 48 groups of data from 12 patients were analyzed. There were no significant differences in CI [(4.75±0.93) L ? min(-1) · m(-2)vs. (4.69±0.89) L · min(-1) · m(-2)], GEDI [(780.60±109.30) ml/m2 vs. (784.75± 106.20) ml/m2] and ELWI CC11.61±3.45) ml/kg vs. (11.54±3.56) ml/kg] between the interruption and process of CVVH, as obtained by the pared t-test (all P>0.05).
