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 investigate the relationship between the oxidative injury induced by low glucose and mitochondrial membrane potential in HUVEC-12 cells. Methods Human umbilicalvein endothelial cells HUVEC-12 were cultured in low concentration glucose for 4 h.Cell viability of HUVEC-12 cell was assessed with MTT assay.Dihydroethidium (DHE) was used as a reactive oxygen species (ROS)capture, which was detected the mean fluorescence intensity of samples and Rhodamine 123 as a fluorescence detector was to measure the level of mitochondrial membrane potential (MMP) in cells.Results Comparing to HUVEC-12 cells viability in 5.5 mmol/L glucose group (96.80 ±3.20)%, cells exposed to 2.8 mmol/L glucose group (66.40 ± 1.60) % and 0 mmol/L glucose group (58.93 ± 1.67) % were decreased by 32% and 40% respectively (P < 0.01).ROS level of 5.5 mmoL/L glucose group, 2.8 mmol/L glucose group and 0 mmol/L glucose group were 0.59 ± 0.02, 0.74 ± 0.04 and 0.88 ± 0.05,respectivdy, increased by 25% in cells exposed to 2.8 mmol/L glucose and by 48% in cells without glucose exposure comparing to 5.5 mmol/L glucose group (P <0.01) ; MMP levels of 5.5 mmol/L glucose group,2.8 mmoL/L glucose group and 0 mmoL/L glucose group were 148.83 ± 3.51, 271.07 ± 19.54 and357.74 ±51.32 respectively, increased to 1.8 times in cells exposed to 2.8 mmol/L glucose and to 2.4times in cells without glucose exposure comparing to 5.5 mmoL/L glucose group (P < 0.01).Conclusion Low glucose leads to injury in HUVEC-12 cells, which is probably induced by the oxidative stress via the increasing MMP.

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.

OBJECTIVETo observe the effect of the IgY solution on dental plaque and mutans Streptococci in plaque and in saliva.
METHODSA double-blind study was used. 44 school children at the third grade in test group used the IgY solution for 21 days; 41 children in control group used the placebo. The plaque index, the plaque weight, the level of mutans streptococci in saliva and in plaque were tested for all children.
RESULTSThe plaque weight in test group was (46.4 +/- 31.2) mg at baseline, and (36.6 +/- 25.6) mg at the end of the study (P = 0.007). The IgY solution reduced 21.1% plaque weight. Statistically significant differences for other indices were not shown in this study.

OBJECTIVETo investigate the nephrotoxic effects of methyl cantharidimide tablets on urinary protein and enzymes in Beagle dogs.
METHODBeagle dogs were randomly divided into negative control group(blank tablet), methyl cantharidimide tablets group (6.11,12.21, 24.42 mg x kg(-1)), continuously 30 days of oral adminiStration, once a day. The drug and control group were collected and determined fresh urine in 1, 2, 3 and 4 weeks of the administration; Serum urea nitrogen (BUN), creatinine (Crea), total protein (TP) and albumin (ALB) as well as sodium, potassium, chloride electrolyte were determined on 15 and 30 days of the administration; Urine albumin (mAlb), kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin( NGAL), N-acetyl-beta-D-glucosaminidase (NAG), clusterin, beta2-microglobulin (beta2-MG), alpha1-microglobulin (alpha1-MG), alanine aminopeptidase( AAP) and im- munoglobulins IgG were tested on 15 and 30 days of the administration.
RESULTCompared with the control group, urine protein and white blood cells was significantly increased in each dose group. On 15 days of the administration, mAlb were higher in each dose group, KIM-1, NGAL, clusterin, NAG and AAP were significantly higher in high-dose group, while the middle and low dose group had no significant difference, as well as blood SCr and BUN no obvious abnormalities. On 30 days, mAlb, KIM-1, clusterin, NAG, AAP were increased in each dose group, appearing dose-effect relationship, beta2-MG and NGAL levels were significantly increased in high-dose group. Contents above indicators were increased with significant dose and time relationship, and serum BUN, Scr were correlated, suggesting that urine mAlb, KIM-1, clusterin, NAG and AAP indicators that can sensitively respond the changes of proteins and enzymes in urine.
CONCLUSIONMethyl cantharidimide tablets has a renal toxicity, urine mAlb, KIM-1, clusterin, NAG and AAP can be used as the early nephrotoxic biomarkers of methyl cantharidimide tablets.
