BACKGROUND:Vascular endothelial injury usually appears following atherosclerosis, hypertension, diabetes mellitus and other diseases, which can be repaired by endothelial progenitor cells (EPCs) in the systemic circulation. OBJECTIVE:To study the effect of salveanolic acid B on the mobilization and adhesion of EPCs in mice. METHODS:Thirty C57BL/6 mice were selected and randomly divided into surgical and non-surgical groups, (n=15 per group). Common carotid arteries of mice in the surgical group were injured by iron wire, then were subdivided into three groups (n=5 per group), and were given the injection of 5% of glucose (control group), 100 g/L salveanolic acid B and 10 μmol/L vascular endothelial growth factor, respectively. Meanwhile, the mice in the non-surgical group received the same assignment and treatment, but the common carotid arteries were not injured. After consecutive 7-day administration, the EPCs in the peripheral blood of the mice were isolated, and the EPCs adhesion was tested by flow chamber experiment. The serum levels of stromal cell-derived factor-1 and interleukin-8 were detected by ELISA kits. RESULTS AND CONCLUSION:The proportion of EPCs in the surgical group was significantly increased compared with the non-surgical group (P < 0.05). After 7-day administration, the proportion of EPCs in the salveanolic acid B and vascular endothelial growth factor subgroups of the surgical group was significantly higher than that in the control subgroup (P < 0.05); the proportion of EPCs in the vascular endothelial growth factor subgroup of the non-surgical group was significantly higher than that in the control and salveanolic acid B subgroups (P < 0.05). Flow chamber experiment revealed that the number of EPCs in the salveanolic acid B subgroup was significantly more than that in the control subgroup (P < 0.05). In the surgical group, the serum levels of stromal cell-derived factor-1 and interleukin-8 in the in the salveanolic acid B and vascular endothelial growth factor subgroups were significantly higher than those in the control subgroup (P < 0.05); in the non-surgical group, the serum levels of stromal cell-derived factor-1 and interleukin-8 in the in the vascular endothelial growth factor subgroup were significantly higher than those in the control subgroup (P < 0.05). To conclude, salveanolic acid B can increase the efficiency of the EPCs mobilization in bone marrowin vivo, help the EPCs adhere to the collagen surface, and upregulate the serum levels of stromal cell-derived factor-1 and interleukin-8.

Objective To develop Z-score reference ranges for tricuspid annular plane systolic excursion(TAPSE) in normal fetuses from the measurements of gestational age(GA),biparietal diameter (BPD) or femur length(FL) using fetal echocardiography.Methods A retrospective cross sectional study of 1012 singleton normal fetuses were performed.The gestation age ranged from 20 to 41 weeks.Non-cardiac fetal biometric parameters included GA and BPD and FL were measured and calculated GA based on menstrual age.TAPSE was measured in a standard apical four-chamber view by free angle M-mode echocardiography.Normal Z-score ranges were developed for TAPSE using GA,BPD and FL as independent variables.These were accomplished by using first standard regression analysis and then weighted regression of absolute residual values for each parameter in order to adjust for inconstant variance.Results Linear regression model was the best description of the data in each case and correlations between TASPE and independent variables (GA,BPD,FL) were excellent.Heteroscedasticity of standard deviation (SD) with increasing independent variables also could be modeled with a simple linear regression.According to these equations,TAPSE Z-score =(the actual measurement of TAPSE-predicted TAPSE)/prediction SD.Conclusions Normal reference ranges and Z-scores for TAPSE have been provided.These normative data may be useful tools for assessment of fetal TAPSE,to evaluate fetal right ventricular function more accurately and effectively.

Objective:To study the detecting rate of nonfermenters and their resistance to the antibiotics in nosocomial infections in our hospital. Methods:The bacteria were identified by VITEK-AMS, the susceptibility tests(K-B method) were done according to the NCCLS standard and the results were analyzed. Results: The detecting rate of nonfermenters was 14. 29%. The most common bacterium was P. aeruginosa (the component ratio was 44. 22%). followed by A. baumannnii (32. 17%) and S.maltophilia(9.23%). The infectious rates of nonfermenters were different at different infectious sites, with the highest rate in the respiratory system and the lowest in central nervous system. The resistant rate to the antibiotics of P. aeruginosa was 45. 21% ,of A. baumannnii 47. 85% and of S. maltophilia 64. 02%. Conclusion:The detecting rate of nonfermenters is rather high in the nosocomial infection in our hospital. Due to the high resistant rates of nonfermenters to the antibiotics , the drugs should be chosen accoding to the result of the drugs susceptibility test.

Objective To establish z-score model for fetal tricuspid annular plane systolic excursion(FAM-TAPSE) and mitral annular plane systolic excursion(FAM-MAPSE) based on gestational age(GA),then to evaluate the ventricle systolic function of fetus with heart failure.Methods One thousand and twelve normal fetuses and 24 fetuses with heart failure were involved. FAM-TAPSE and FAM-MAPSE were measured by free angle M-mode echocardiography,and FAM-TAPSE and FAM-MAPSE z-score models of normal fetuses were constructed by using first standard regression analysis with GA as independent variable.The fetuses with heart failure were divided into left heart failure (LHF) group and right heart failure (RHF) group by Tei index.Subsequently,the two parameters between normal and fetuses with heart failure were compared. Results The models used to calculate z-score for FAM-TAPSE and FAM-MAPSE were constructed,and GA had close correlation with them. Compared with normal fetuses,the mean z-scores of FAM-TAPSE and FAM-MAPSE were statistically different in fetuses with heart failure(P<0.001). The FAM-MAPSE z-scores of LHF and the FAM-TAPSE z-scores of RHF were all less than-2 z-scores.Conclusions The FAM-TAPSE and FAM-MAPSE z-scores decline in fetuses with heart failure and they can provide quantitative evidence in evaluation of heart systolic function,FAM-TAPSE and FAM-MAPSE z-score would be markers for assessing heart systolic function in fetuses with heart failure.

Objective To obtain the annular plane systolic excursion difference (APSED)of fetuses in second and late trimester by free angle M-mode (FAM)and tissue motion of annular displacement (TMAD)in order to assess the fetal ventricular function.Methods The mitral annular plane systolic excursion(MAPSE)and tricuspid annular plane systolic excursion(TAPSE)of four hundred and fifty five normal fetuses from 20 to 41 weeks were measured by FAM echocardiography,and the difference between them were calculated.Early diastolic velocities (Em)of the mitral annular and early diastolic velocities (Em')of the tricuspid annular were estimated by pulsed-wave tissue Doppler imaging (TDI),meanwhile systolic velocities (Sm)of the mitral annular and systolic velocities (Sm')of the tricuspid annular were also estimated by TDI.Fifty normal fetuses in the second and late trimester were choosed randomly,two-dimension imaging was obtained at the apical four-chamber view,then mitral annular plane and tricuspid annular plane displacement curve were acquired at the same time by using off-line QLab 8.1 software,and the differences in the peak time between them were compared.The trace of annular displacement were recorded by color tissue tracking technology.Results There was a significant difference between FAM-TAPSE and FAM-MAPSE in different gestational weeks (P <0.05),FAM-TAPSE was growing with the increase of gestational weeks,FAM-APSED showed significant positive correlations with gestational week, Em,Sm,Em' and Sm'.Annular plane displacement curve showed that TMAD-TAPSE was higher than TMAD-MAPSE in the entire cardiac cycle,and there was no statistically significant difference in time to peak of the annular plane displacement curve between them(P >0.05).Conclusions The APSED existed in the second and late trimester continually.It was considering associated with fetal ventricular torsion.As the growth of gestational weeks,the increase of APSED reflected the enhanced reserve capacity of the fetal ventricular torsion.APSED can reflect the longitudinal motion and torsion movement of fetal ventricle quantitatively,and can be used as a new index to assess the fetal cardiac function.

Plantar pressure distribution can reflect the force of several key points on foot while standing and walking. A comprehensive understanding of the plantar pressure distribution makes great sense in the following aspects: the understanding of the normal foot biomechanics and function, clinical diagnosis, measurement of disease extent, postoperative efficacy evaluation, and rehabilitation research. A simple plantar pressure measurement device was designed in this study. This paper uses FlexiForce flexible sensor to pickup plantar pressure signal and USB A/D board to do data acquisition. The data are transferred into a laptop and processed by a VB-based software which can display, remember and replay the data. We chose patients with hallux valgus and normal people to measure the pressure distribution and make contrast analysis of plantar pressure with this device. It can be concluded that people with hallux valgus have higher pressure on the second metatarsophalangeal joint and the distribution move outward. The plantar pressure of patients postoperative could be greatly improved compared to the preoperative. The function of this device has been confirmed.
