Objective To explore the inhibiting effects of arsenic trioxide and cisplatin on MG-63 cells. Methods Using MTT assay,flowcytometry,phase contrast microscopy and electron microscopy methods,the therapeutic effect of arsenic trioxide was studied for the osteosarcoma in the cultured MG-63 cells in vitro,and compared these effects with cisplatin. The inhibitory rotes of cell growth and the effect of apoptosis and cell cycle were compared between arsenic trioxide and cisplatin on MG-63 cells. Results The contrast phase microscope revealed the adhesion ability of normal groups was good and cellular morphology showed epithelium cells. But the celhdar morphology showed irregular arrangement in arsenic trioxide groups and cytoplasmic vacuoles in cisplatin group. Electron microscope revealed the globular plasmalemma ecphymas in cell surface of control groups,the enlarged crista mitochondriales and the double-deck membrane structure appeared clearly. But electron microscope revealed globular plasmalemma processes in cell surface of arsenic trioxide groups,thinned crista mitochondriales and clearly seen karyopycnosis and nuclear membrane of apoptotic cells. The globular plasmalemma processes in cell surface of cisplatin groups were separated,nuclear membrane thickened and chromatin were in sandy shape. Both arsenic trioxide and cisplatin inhibited effectively MG-63 cells growth. There was a significant difference in different groups of inhibition ratios to the growth of cells(all P < 0.05). In 2,4,8,16,32,64,128 hours,the inhibition ratios(%) of arsenic trioxide(56.31±0.03,70.00±0.06,79.84±0.03,87.31±0.13,84.70±0.09,90.68±0.06,91.18±0.05) and cisplatin groups(7.55±0.15,15.70±0.17,30.72±0.07,49.80±0.05,45.11± 0.13,61.62±0.08,93.80±0.12) were obviously increased as compared with those in the control group(2.03± 0.07,2.78±0.08,3.11±0.01,5.67±0.04,12.23±0.04,18.65±0.04,24.45±0.04,all P < 0.05). Moreover the inhibition ratio of arsenic trioxide group in 2 to 32 hour was significantly higher than that of cisplatin group and the effect was more faster(all P < 0.05). Both arsenic trioxide and cisplatin could induce apoptosis MG-63 cells. There was a significant difference in different groups of the inhibition ratio to the growth of cells(F = 13.317,P < 0.05). The inhibition ratios(%) of arsenic trioxide on 24,36,48 hour(20.50±3.78,45.76±9.90,25.16±15.41),and cisplatin groups on 24,36,48 hour(12.55±1.51,18.85±3.40,12.37±5.43),were obviously increased as compared with those in the control group at the same time(6.57±1.48,8.03±2.08,6.54±1.30,P< 0.05 or<0.01). Both arsenic trioxide and cisplatin inhibited MG-63 cells cycle. There was a significant difference in different groups of the inhibition ratio to the growth of cells(F = 54.579,43.429,21.795,P < 0.05 or < 0.01). And the total inhibition ratios(%) in G1 cycle of arsenic trioxide(78.26±5.24) and cisplatin groups(80.48±2.81) were obviously increased as compared with those in the control group(57.49±6.65,all P < 0.05 or < 0.01). Conclusions Arsenic trioxide and cisplatin can effectively inhibit the proliferation of MG-63 cell line and induce the apoptosis of MG-63 cell line. And the effects induced by arsenic trioxide group were faster than that of cisplatin groups. Moreover arsenic trioxide can arrest the cell cycle of MG-63 cell line at G1 phase.

OBJECTIVETo evaluate the application of shear wave elastography (SWE) combined with transition zone biopsy in the detection of prostate cancer (PCa).
METHODSA total of 489 patients with suspected PCa underwent transrectal ultrasonography (TRUS) and SWE-guided prostatic biopsy. We evaluated the role of SWE combined with transition zone biopsy in promoting the detection rate in comparison with the results of biopsy pathology.
RESULTSThe pathological results confirmed 221 malignant and 268 benign cases. Based on systematic biopsy, SWE combined with transition zone biopsy achieved a detection rate of 45. 19% , significantly higher than that of systematic biopsy alone (33.13%) (P < 0.05). The diagnostic sensitivity, specificity, and accuracy of SWE were significantly better than those of TRUS (P < 0.05). The mean elasticity (Emean) of SWE was remarkably higher for malignant than for benign lesions ([40.1 ± 9.5] vs [21.6 ± 8.3] kPa, P < 0.05). With 28.5 kPa as the threshold of the Emean value, the area under the ROC curve was 0. 899, and the diagnostic sensitivity and specificity were 88.71% and 86.23%, respectively.
CONCLUSIONSWE combined with transition zone biopsy could significantly improve the detection rate of prostate cancer.

Objective To establish a economic and stable method to induce and culture dendritic cells (DCs) from peripheral blood of human being, and compare with the magnetic activated cell sorting. Methods Monocytes were isolated from health donors peripheral blood mononuclear cells(PBMC) by density gradient separation,cultured and compared with that of cells isolated by the magnetic activated cell sorting or adherent culture,respectively. PBMC were cultured with recombinant human granulocyte macrophage colony stimulating factor (rhGM-CSF) and recombinant human interleukin-4(rhIL-4) for 6 days to induce the growth of DCs. Morphological changes was observed under inverted microscope. Meanwhile, cell viability was tested at the 3rd, 5th, 6th day,respectively. The phenotypes, like CD14, CDla, HLA-DR were analyzed with flow cytometry after PBMC were adherent cultured for 1, 2, 5 h. After adding human recombinant cytokines, the phenotypes of acquired cells surface markers, CD14, CD1a, CD86, CD83 and HLA-DR would be detected and compared with flow cytometry. T cells proliferating activity was determined by allogeneic mixed lymphocyte reaction in vitro. Results After adherent culture for 2 h, the acquired DCs showed typical morphology. Cell viability was decreased at days 5th, 6th[(53.333 ±5.774)%,(38.333 ± 7.638)%] than that at day of 3rd[(68.667 ± 3.215)%, all P < 0.05] with the magnetic activated cell sorting, but with adherent culture method, the difference was not statistically significant (F = 0.737,P> 0.05) at days of 3rd, 5th, 6th[(92.667 ± 3.055)%,(94.000 ± 1.000)%,(94.667 ± 1.528)%]. Moreover,compared with the magnetic activated cell sorting, there were differences in cell viability of adherent culture method at days of 3rd, 5th, 6th(t = 9.374, 12.021,12.527, all P < 0.05). Before and after using the magnetic activated cell sorting, the expression of CD14 were (32.457 ± 12.351) %, (41.914 ± 14.858)%, respectively. The difference was not statistically significant(t = 1.295, P > 0.05). After culturing for 2 h, the expression of CD14[(35.267 ± 4.658)%]was higher than those of culturing for 1, 5 h[(15.033 ± 6.189)%, (21.233 ± 4.895)%, all P < 0.05]. Compared with the 1st day[(32.328 ± 14.517)%], the CD14 expression level[(2.200 ± 1.356)%] on surface of DCs was significantly reduced(t = 5.467, P < 0.05) at the 6th day of culturing, the CD1a expression level[(43.371 ±16.250)%] was remarkablely increased than that of the 1st day[(12.300 ± 6.223)%, t = 2.545, P < 0.05];while the expressions of CD86, CD83, HLA-DR[(16.857 ± 5.686)%,(9.343 ± 5.230)%,(72.800 ± 17.881)%] were similar(t = 0.652,1.137,0.907, all P > 0.05) compared with that of the 1st day[(12.550 ± 16.758)%, (6.250 ±1.323)%, (64.671 ± 15.588)%]. In mixed lymphocytes reactions, with increasing of lymphocytes, T lymphocytes proliferating activities were reduced. In the magnetic activated cell sorting, when the ratio of DCs and lymphocytes were 1: 50, 1: 100, cells proliferation ability(1.502 ± 0.055,1.507 ± 0.029) were lower than that of ratio of 1: 10(1.859 ± 0.049, all P < 0.05);in adherent culture method, the ratio of DCs and lymphocytes was 1: 100, the cells proliferation ability(1.545 ± 0.066) was decreased than that of ratio 1: 10(2.015 ± 0.301, P < 0.05). When the proportion of DCs and lymphocytes remained the same, the capacity to stimulate T lymphocyte was similar of the two methods(P > 0.05). Conclusions Comparied with the magnetic activated cell sorting, after culture of PBMC for 2 h the induction of DCs can produce better formed and functional cells, and this method is stable, simple,economic, and is a suitable method for basic and clinical research of DCs in vitro.

Objective To compare the effect of right ventricular outflow tract (RVOT) and right ventricular apex (RVA) pacing on ventricular systolic synchrony using gated blood pool SPECT (GBPS).Methods A total of 50 patients implanted with pacemaker due to high degree or complete atria-ventricular block were enrolled in the study. Twenty-three patients were RVOT paced ( Group A, n = 23) and 27 were RVA paced (Group B, n=27). Twenty-four patients with malignancy, normal echocardiographic findings and no history of cardiac diseases were scheduled for pre-chemotherapy evaluation of cardiac structure and function and were enrolled as control group ( Group C, n = 24). All patients underwent GBPS imaging and the values of phase angle (PS), mean phase of each wall, standard deviation (SD) of mean phase of each wall, lateral-septal motion delay of left ventricle ( LV Sep-Lat Delay), septal-right ventricular (RV) delay of LV ( LV Sep-RV Delay) and LV-RV Delay were acquired. The parameters of ventricular systolic synchrony among the three groups were compared using one-way ANOVA. Results The mean phase of LV lateral wall in Groups A and B were significantly higher than that in Group C: Group A (120.50 ±40.58) ms; Group B (103.23±28.34) ms; Group C (84.63 ±22.38) ms (F=7.72, P <0.05). There was no significant difference between Groups A and B ( t = 1.30, P > 0.05 ). The mean phase of RV in Group A was significantly larger than those in Groups B and C: Group A ( 137.05 ± 39.27) ms, Group B ( 100.85 ± 23.79) ms,Group C (59. 13 ±30.52) ms (F=35.55, P<0.05). PS, SD and LV Sep-Lat Delay in Groups A and B were significantly higher than those in Group C: (85.73 ± 12.00)°vs (89.85 ± 15.61 )°vs (58.95 ±9.87)°, (27.68±10.66) ms vs (26.15 ±13.02) ms vs (15.63 ±8.35) ms, (25.06±34.23) ms vs (2. 62 ± 60. 31 ) ms vs ( - 23.66 ± 31.39) ms, F = 41.54,8.55,6.81, all P < 0.01 ), however, there was no significant difference between Groups A and B ( t = 0. 68, 0.68, 1.30, all P > 0.05 ). LV Sep-RV Delay and LV-RV Delay were significantly different among the three groups ( LV Sep-RV Delay: Group A (57.60 ±56.77) ms, Group B (6.36 ±61.88) ms, Group C ( -41.89 ±35.78) ms; LV-RV Delay:Group A (47.36 ±42.59) ms, Group B ( 3.08 ± 38.81 ) ms Group C ( - 26.50 ± 20.99 ) ms, F = 20. 32,25.38, both P < 0.01 ). Conclusion Both RVA and RVOT pacing increase the segmental phases detected by GBPS, causing inter- and intra- ventricular asynchrony compared with patients without pacemakers.
