Falling in the elderly is a major health problem and may cause severe consequences. Fall risk assessment is important for preventing and intervening fall incidence. Inertial Measurement Unit (IMU) has been introduced to evaluate motion/balance function and fall risk among the older people. Some researches indicated that it might have advantages over the usual tools, and can be used in the hospitals, communities, nursing homes, etc. IMU is a good way to measure gait variability, which may be strongly related with the risk of falls.

OBJECTIVE:To observe the clinical efficacy and safety of piperazine ferulate combined with glutathione in the treatment of diabetic nephropathy. METHODS:80 patients with diabetic nephropathy in our hospital were divided into observation group and control group according to random number table,with 40 cases in each group. Both groups was given general treatment as blood glucose,blood lipid and blood pressure control. Control group was additionally given Reduced glutathione tablets 400 mg, tid,on the basis of general treatment. Observation group was additionally given Piperazine ferulate tablets 100 mg,tid,on the ba-sis of control group. Both groups were treated for 12 weeks. The fasting plasma glucose(FPG),2 h postprandial plasma glucose(2 hPG),blood pressure,blood lipid,serum creatinine (Scr),blood urea nitrogen (BUN),24 h urinary total protein and albumin, urine β2 microglobulin(β2-MG)and N-acetyl-β-glucosaminidase(NAG)of 2 groups were detected before and after treatment. The occurrence of ADR was observed. RESULTS:Before treatment,there was no statistical significance in FPG,2 hPG,blood pres-sure,blood lipid,Scr,BUN,24 h urinary total protein and albumin,urine β2-MG and NAG between 2 groups(P>0.05). After treatment,above indexes of 2 groups were improved significantly,and the observation group was better than the control group, with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:In the treatment of diabetic ne-phropathy,piperazine ferulate combined with glutathione can improve blood glucose,blood pressure,blood lipid levels and renal function with good safety.

Objective To investigate the effect of perinatal bisphenol A BPA exposure on brain development of F1 male offspring. Methods Pregnant SD rats were given BPA at 2 20 and 100 mg/kg body weight per day respectively from eleventh day of gestation to the whole lactation by gavage until their pups were weaned on postnatal day 21  the control group had no BPA exposure. Every six F1 male pups from each of the four groups were killed at differential time points on postnatal day 1510152130 and 45 respectively. Histopathological examination by HE stain was done on the brains. Results The results showed no abnormal change was found on postnatal day 1-10. Three dosage groups showed abnormal change of different degree on 15th 21th 30th postnatal day the mainly abnormal change was karyopyknosis of pyramidal cell in CA3 of hippocampus and cortical neuron in cerebral cortex. The cell numbers of pyramidal cell in CA3 of hippocampus and cerebral cortex were decreased on 45th postnatal day. Conclusion Perinatal BPA exposure may have an adverse effect on the brain developmnent of F1 male offspring.

Objective To evaluate the value of the change of B-type natriuretic peptide(BNP) in predicting weaning outcome of patients with mechanical ventilation in ICU.Methods We carried out a prospective cohort study on patients in ICU at Fuxing Hospital from July 2013 to January 2014.Patients expected to use mechanical ventilation for more than 24 hours were enrolled in our study.The plasma concentration of BNP was measured at the beginning of spontaneous breathing trial(SBT) and 2 hours after.According to the outcome of SBT,patients were divided into SBT failure group (group A),weaning failure group (group B) and weaning success group (group C).The levels of BNP before and after the SBT were compared among three groups.The receiver operating characteristic (ROC) curve analysis was used to evaluate the changes of BNP (△BNP) and the rate of change (△BNP％) in predicting weaning outcome.Results A total of 56 patients were enrolled in our study,12 in group A,11 in group B and 33 in groupC.In groupC,both△BNPand△BNP％ [7.0,(-1.2,45.5) ng/L;6.1 (-2.1,11.5)％]were significantly lower than those in group A [88.0 (58.0,140.0) ng/L,P ＜ 0.05;20.5 (15.3,40.3) ％,P＜0.001]and group B[46.0 (17.5,91.2) ng/L,P＜0.001;24.3(13.0,32.5) ％,P＜0.001].The area under ROC curve (AUC) of △BNP％ to predict weaning success was 0.88 [95％ CI 0.79-0.97;P ＜0.001] and the cut-off value is 13.4％ with relatively high sensitivity(84.8％)and specificity(82.6％).The AUC of △BNP to predict weaning success was 0.80 [95％ CI 0.69-0.92;P ＜ 0.001] and the cut-off value is 80ng/L with high sensitivity 93.4％ and mediocre specificity (47.9％).Conclusion Either △BNP％ or △BNP in the SBT can predict weaning outcome,in which △BNP％ seems better than △BNP.

Objective To investigate the inhibitory effect of a disintegrin and metalloprotease 12 silenced by shR?NA on self-renewal capacity of CD133 positive giloma cells. Methods The shRNA recombinant lentivirus aimed at si?lencing ADAM12 was prepared. Human glioma cells U87 were employed in this study and assigned into three groups:shRNA-ADAM12, shRNA-NCandshRNA-C. ADAM12 expression was detected at mRNA and protein level using Re?al-time quantitative-PCR and western bloting, respectively. U87 cells were cultured with stem cell culture medium, to obtain cell sphere formation in which CD133 positive glioma cells were enriched. Immunofluorescence was employed to detect the expression of ADAM12 and CD133 in cell spheres and U87 cells; Self-renewal was tested by using tumor sphere formation assay. Molecular markers for differentiated or undifferentiated cells (CD133,GFAP and Tuj1) were de?tected at protein using western blotting. Western blotting was employed to test protein expression of HES1. Results AD?AM12 shRNA significantly down-regulated the mRNA and protein expression levels of ADAM12. Compared with shRNA–C group, the relative expression levels of mRNA in shRNA-ADAM12 group and shRNA-NC group were 0.22 ± 0.03 and 0.98 ± 0.06 (F=425.37,P<0.01). The relative expression levels of protein in shRNA-ADAM12 group, shRNA-NC group and shRNA-C group were 28.72%±2.36%, 69.21%±3.92%and 69.04%±3.57%, respectively (F=145.42,P<0.01). Immunofluorescence staining showed that expression levels of ADAM12 and CD133 in cell spheres were significantly higher than those in normal cells. The number of spheres in three groups were 45.5±2.3、104.2±5.8 and 109.6±6.2, tumor sphere formation ability of shRNA-ADAM12 group was lower than that of shRNA-NC group and shRNA-C group (F=147.03,P<0.01). Compared with the shRNA-NC group and shRNA-C group, the protain expression of GFAP and Tuj1 were increased up to 166% and 146% (P<0.01) whereas the protein expression levels of CD133 and HES1 were down-regulated by 54% and 50% (P<0.01). Conclusion Knockdown of ADAM12 may suppress self-renewal ability of CD133 positive glioma cells by inhibiting the Notch pathway activity.

Light intensity, gas temperature, soil temperature and gas exchange parameters were determined of three years old Panax notoginseng planted on different layers seedbed and different location (left, middle, right) of the same layer in greenhouse. Result show that diurnal variation of light intensity, gas temperature and soil temperature showed that upper layer > middle layer > lower layer; different locations of the same layer showed that light intensity of upper layer was not different among different locations; light intensity of middle and lower layer in right and left were the same, and significantly higher than those in the middle position; the gas temperature of each layer all with less different of each location; soil temperature of 12 cm depth is the lowest, and was gradually increased to the upper and lower surface; net photosynthetic efficiency of P. notoginseng showed that upper layer > middle layer > lower layer; there were significant correlation between soil temperature, stomatal conductance, intercellular CO2 concentration and photosynthetic rate were correlated with light intensity significantly; transpiration rates had notable correlation with light intensity and gas temperature. All above indicated that net photosynthesis rate of P. notoginseng was affected by light intensity directly, gas temperature and soil temperature indirectly. Inconclusion, stereoscopic cultivation of P. notoginseng was practicable in present study. The planting quality of P. notoginseng under stereoscopic cultivation could be improved by ameliorate the structure of seedbed to enhance the light intensity of middle and lower layer. Increase the thickness of the seedbed to decrease the temperature difference of soil. Further the management of ventilation facilities of greenhouse to control the gas temperature.
