Objective:To explore the changes of chemotherapy sensitivity of breast cancer MCF-7/ADM cells after Hiwi gene targeting silence, and to illuminate the role of Hiwi gene in resistant mechanism of breast cancer MCF-7/ADM cells.Methods:The MCF-7/ADM cells were transfected with Hiwi control,siRNA1 Hiwi gene and siRNA2 Hiwi gene as Hiwi control group, Hiwi siRNA1 group and Hiwi siRNA2 group.The expression levels of Hiwi gene mRNA and protein in breast cancer MCF-7/ADM cells were detected by Real-time PCR and Western blotting methods to judge the transfection rates in various groups.After transfection,the breast cancer MCF-7/ADM cells in various groups were treated with the different concentrations(0,0.1,0.5 and 1.0 mg·L-1) of adriamycin, and the cell resistant sensitivities were detected by MTT method.Results:Compared with control group(0 mg·L-1 adriamycin), the expression levels of Hiwi gene mRNA and protein inMCF-7/ADM cells in Hiwi siRNA1 and Hiwi siRNA2 groups were significantly decreased (P<0.01).Compared with control group, the survival rates of Cells in Hiwi siRNA1 and Hiwi siRNA2 groups were significantly decreased after treated with different concentrations of adriamycin,and the survival rates in Hiwi siRNA1 and Hiwi siRNA2 groups were significantly decreased(P<0.01);they were (48.15±6.28)% and (41.73±6.17)% when the concentration of adriamycin was 1 mg·L-1,and the sensitivities to the adriamycinwere obviously enhanced(P<0.01).Conclusion:The target silencing Hiwi genes in MCF-7/ADM cells is efficient.The sensitivity of MCF-7/ADM cells to adriamycin restores after Hiwi gene silencing.

Objective To observe the influence of exercise intensity on cardiorespiratory function in the elderly with coronary heart disease using simplified 24-action Taijiquan and jogging. Methods A total of 115 sedentary elderly patients with heart disease were randomly divided into a control group ( no exercise), a low-intensity exercise group, a medium-intensity exercise group (whose exercise was simplified 24-action Taijiquan at 40-60% of their individual maximum oxygen consumption (VO2max) for 90 to 200 minutes per week) and a high-intensity exercise group ( whose exercise was jogging on a treadmill at ＞ 70% of their maximum oxygen consumption for 200 minutes per week). The regime was maintained for 6 months. All patients accepted a treadmill exercise test before and after the 6 months of exercise to evaluate the changes in VO2max, maximum heart rate ( HRmax), VO2max/HRmax and exercise time (t). Results ( 1 ) After 6 months of exercise, VO2max, HRmax, VO2/HRmax and t had increased sisnificantly in all three exercise groups. Work capacity had increased 18.6% , 33% and 34.4% and HRmax had increased 9.3% , 13.8%, 19.1%. There was no difference between before and after in the control group. (2) Compared with the control group the average VO2max, HRmax and t of all three exercise groups had increased significantly. VO2 max was 9.4% , 26% and 23. 1% better; HRmax was 6.7% , 8.8% and 12% better; t was 3.5,4 and 4.9 minutes longer. (3) Compared with the low-intensity exercise group, VO2max, HRmax and t in the medium- and high-intensity groups increased significantly more. VO2max increased 16.6% and 13.7% more; HRmax increased 2.1% and 3.2% more and average t was 0.5 and 1.4 minutes longer. (4) There was no significant difference between the medium- and high-intensity exercise groups in terms of VO2max. (5) The incidence of self-reported adverse responses to exercise such as dizziness, chest stuffiness and fatigue in the high-intensity exercise group increased significantly compared with the other 3 groups. Conclusions Exercise can gradually improve cardiorespiratory function in the sedentary elderly with heart disease. The effects of medium-intensity exercise are similar to those of high-intensity exercise, but medium intensity is safer.

Objective To explore the effect of band power and wavelet packet entropy in the recognition of hand imagery.Methods The data gained from brain computer interface competition in 2003 provided by Graz University of Technology.The electroencephalogram(EEG)signals between 8～16 Hz were decomposed by db3 wavelet packet at three levels.The band power(BP)and wavelet packet entropy(WPE)of C3 and C4 were calculated respectively.The BP and WPE were defined as the feature vector.The left and right hand motor imaginary tasks were distinguished.Results The proposed method was applied to the test data set with 140 trails.The satisfactory results were obtained with the highest classification accuracy 87.14%.Conclusion The band power and wavelet packet entropy of EEG changed with time is coincident with event-related desynchronization and event-related synchronization.It can be used to recognize the left and right band motor imaginary tasks.

ObjectiveTo explore the effects of insomnia on heart rate variety(HRV) in aged hypertension patients. Methods259 subjects were divided into healthy group (74 cases),simple hypertension group (71 cases),coexisting hypertension and insomnia group (114 cases) which was sub-grouped to ＜5 years,5-9 years and ≥-10 years according to the duration of insomnia.All subjects had 24 h recordings of ECG.The data of HRV time domain (SDNN,SDANN and ASDNN) were collected and compared.ResultsHRV time domain was lower in healthy group than in the other two groups (F=12.02,10.54 and 4.27,P＜0.01),and decreased more significantly in coexisting hypertension and insomnia group compared with simple hypertension group(P＜0.01).The values of SDNN and SDANN in 5-9 years and ≥ 10 years subgroups decreased as compared with ＜ 5 years subgroup (F=8.63 and 4.54,P＜0.01),and these values further lower in ≥10 years subgroup than in 5-9 years subgroup (P＜ 0.01 ). ConclusionsInsomnia may lead to more serious disorder of automatic nervous system and further aggravated disorders appear in the elderly with hypertension along with increasing years of insomnia.

Objctive:To investigate the immunohistochemical and morphological characteristics of the papillary thyroid microcarcinoma(PTM) ,and differential diagnosis of the related disease.Methods:The morphological characteristics of 223 patients with PTM were observed under light microscope.Seventy-four cases of PTM and 32 cases of proliferative lesion of thyroid were observed under light microscope with stains of hematoxylin and eosin and immunohistochemical staining.The antibody included CK19,MC,Galectin-3 and CD56.Results:Eighty-six cases were follicular-patterned and 31 cases nuclear features were untypical in 223 cases of PTM.The positive expression rates of CK19、MC、 Galectin-3、CD56 were 100.0%,98.6%,98.6% and 4.1% in 74 cases of PTM,and were 37.5%,12.5%,18.8%,68.8% in proliferative lesion of thyroid,respectively.Conclusion:Some cases of PTM show a follicular-patterned and the nuclear features.It is untypical compared with classical papillary thyroid carcinoma.It can be differentiated from proliferative lesion with absence of envelope,obviously various and unusually proliferated follicular cells,sclerotic stroma,neoplastic follicles among the collagen and normal follicles.The wide and intensive expression of CK19,Galectin-3,and the negative expression of CD56 are extremely useful in the diagnosis of PTM,four-marker panel with CK19,Galectin-3,MC and CD56 can improve the specificity and accuracy of the differential diagnosis of PTM.

AIM: To observe the effects of toddalia asiatica aqueous extract (Fei Long No 1, F01) on cardiac function and hemodynamics of acute myocardial ischemia in the animal model. METHODS: High positioned double-ligation of the anterior descending left coronary artery induced acute myocardial ischemia in New Zealand rabbits. F01 268 mg/kg were ip into the acute myocardial ischemic model, Cardiac function and hemodynamic measurements were performed before and after ligation and administration of F01. t -test paired was used for statistical analysis. RESULTS: After ligation all indices was reduced significantly except that LVEDP was markedly increased and t-dp/dt max had little change. After administration of F01 changes of most indices were reversed, and returned to or were close to the baseline. 1.5 h after administration of F01 action was more markedly. But the indices of left ventricle work and consumption of oxygen ( HR, TTI and TTI?HR) were reducing continuously. CONCLUSION: F01 markedly decreases ventricle work and consumption of oxygen of acute ischemic myocardium, so that the contractility, diastolic function of myocardium and cardial output are improved. These are the mechanism of protective effect on myocardial ischemia.

Objective To study the effects of exercise on hemodynamic parameters and cardiovascular humoral factors in the elderly patients with hypertension. Methods The modified Bruce assessment (MBA) was employed in an essential hypertension (EH) group (group 1, n =34) composed by elderly EH patients and a control group (group 2, n =31) composed of normal subjects. Heart rate (HR),systolic and diastolic blood pressure (SBP、DBP), and the quantum and duration of exercise (QE, DE) were explored, while the serum concentrations of nitric oxide (NO), endothelin 1(ET1), atrial natriuretic factor (ANF) and AngiotensinⅡ(AngⅡ) were measured at 3 min before and after treatment. Results There were no significant differences between groups 1 and 2 with regard to HR, SBP, DBP, total DE and peak QE before and after treatment, in addition, at the peak of exercise ( P 0.05). Pretreatment SBP and DBP were significantly and positively correlated with those at the peak of and after treatment ( r =0.648,0.630, P
