The effects of combined RNA interference (RNAi) of human telomerase RNA (hTR) and human telomerase reverse transcriptase (hTERT) genes on telomerase activity in a bladder cancer cell line (BIU-87 cells) were investigated by using gene chip technology in vitro with an attempt to evaluate the role of RNAi in the gene therapy of bladder transitional cell cancer (BTCC). Three TR-specific double-stranded small interfering RNAs (siRNAs) and three TERT-specific double-stranded siRNAs were designed to target different regions of TR and TERT mRNA. The phTR-siRNA, phTERT-siRNA, and the combination of both plasmids phTR+phTERT-siRNA were transfected into BIU-87 cells. The expression of hTR and hTERT mRNA was detected by quantitative fluorescent reverse transcription-polymerase chain reaction, and a telomeric repeat amplification protocol was applied to detect telomerase activity. Growth inhibition of BIU-87 cells was measured by MTT assay. Gene chip analysis was performed to evaluate the effects of the combined RNAi of hTR+hTERT genes on telomerase activity and growth of BIU-87 cells in vitro. The results showed that the expression of hTERT and hTR mRNA was inhibited by pRNAT-hTERT-III, pRNAT-hTR-III, and pRNAT-hTR-III+hTERT-III in BIU-87 cells. The inhibition efficiency of pRNAT-hTERT-III, pRNAT-hTR-III, pRNAT-hTERT-III+pRNAT-hTR-III was 67% for TERT mRNA, 41% for TR mRNA, 57% for TR mRNA and 70% for TERT mRNA in BIU-87 cells respectively. The growth of BIU-87 cells was inhibited and telomerase activity was considerably decreased, especially in the cells treated with combined RNAi-hTR and -hTERT. Gene chip analysis revealed that 21 genes were down-regulated (ATM, BAX, BCL2, BCL2L1, BIRC5, CD44, CTNNB1, E2F1, JUN, MCAM, MTA1, MYC, NFKB1, NFKBIA, NME4, PNN, PNN, SERPINE1, THBS1, TNFRSF1A, and UCC1). The results indicated that hTR-siRNA and hTERT-siRNA, especially their combination, siRNA hTR+hTERT, specifically and effectively suppressed the expression of both hTR and hTERT mRNA and telomerase activity. Molecular biological mechanism by which combined siRNA-TR and -TERT inhibited telomerase activity and growth of BIU-87 cells in vitro may involve the down-regulation of the 21 genes.

Objective The aim of this study was to investigate the femoral head trabecular heterogeneity in Chinese male patients with osteoporotic fracture and their effects on osteoporotie fracture.Methods Human femoral heads were obtained from 11 male osteoporotie fracture (OP) patients ranged from 51 to 82 years old [average age (65±9 ) years old], and 7 male trauma ( TM ) patients ranged from 46 to 75 years old [average age (61±11 ) years old] who underwent total hip arthroplasty within two hours after either osteoporotic or trauma hip fracture.The OP was defined as having a fragility fracture.After laying femoral head as living body position and locating mark, nine trabecular specimens were obtained from femoral heads, each of 6 mm × 6 mm× 7 mm.The cortical shell was not included in each specimen.One cube was selected as the primary compressive trabecular region and the other 8 specimens as non-primary compressive trabecular region.These cubes were scanned using high-resolution microcomputed tomography scanner (μCT).After scanning, the data of total cubes, primary compressive trabecular region and noncompressive trabecular region were used for analysis by t test.Results In OP group volumetric bone mineral deosity(vBMD) [( 182.15±66.00) mg/mm3 vs (223.97±70.92) mg/mm3, t =3.041], tissue bone mineral density (tBMD) [(538.76±64.72) mg/mm3 vs (580.01±63.86 ) mg/mm3, t = 3.160],bone volume fraction (TV/BV) [(0.22 ± 0.06) % vs (0.26 ± 0.07 ) %, t = 2.821], trabecular thickness (Tb.Th.) [( 161.07 ±42.75 ) μm vs ( 205.47 ± 74.44 ) μm, t = 3.233] were significantly decreased while bone surface/bone volume ( BS/BV ) [( 13.75 ± 2.55 ) mm-1 vs ( 12.28 ± 2.70 ) mm-1, t =-2.777] was significantly increased in the non-primary compressive trabecular region than that in the primary compressive trabecular region ( P < 0.05 ).vBMD [( 182.15 ± 66.00) mg/mm3 vs ( 248.05 ±105.48) mg/mm3, t = - 3.598], tBMD [(538.76 ± 64.72) mg/mm3 vs ( 570.54 ± 100.32) mg/mm3,t=-2.108],TV/BV [(0.22±0.06) % vs (0.28±0.12) %, t= -3.466], Tb.Th.[(161.07±42.75) μm vs (200.31 ±96.63) μm, t= -2.866], trabecular number (Tb.N.)[(1.46±0.23)/mm3 vs ( 1.57 ± 0.29)/mm3, t = - 2.396] were significantly decreased while trabecular separation ( Tb.Sp.) [(780.82 ± 144.85 )μm vs ( 653.09 ± 119.64) μm, t = 5.470], degree of anisotropy (DA) ( 1.57±0.20 vs 1.47±0.18, t = 2.930 ) were significantly increased in OP than in TM in the non-compressive trabecular region( P < 0.05 ).No significant differents were found between OP and TM for any of the parameters measured in the primary compressive trabecular region.Tb.Th.[(199.37±68.22)μm vs (176.33 ±71.21 )μm, t = 2.060,P < 0.05] were significantly increased in the primary compressive trabecular region than that in the non-primary compressive trabecular region and no significant differences were found in the other parameters in the all 18 specimens.Conclusions The femoral head trabeculae had a heterogenic distribution in OP.Bone loss in OP primarily takes place in non-compressive trabecular region.Femoral neck fracture cannot be prevented though the bone microstructure do not loss in the primary compressive trabecular region.Tb.Th.in the femoral head could be an interesting parameter which is closely related to the femoral neck fracture.

Objective To investigate the effects of pulsed electromagnetic fields (PEMFs) of different intensities on bone metabolism in ovariectomized rata. Methods Sixty 10-month-old female Sprague-Dawley rats were randomly divided into a normal group, an ovariectomized control group, a 0. 14 mT group, a 0. 16 mT group, a 0.18 mT group and an estrogen group. All rats except those in the normal group were subjected to bilateral ovariectomy. Beginning one week after the operation, the rats in the 0. 14 mT, 0. 16 mT and 0.18 mT groups were treated with PEMFs at 50 Hz, 60 min daily for 90 days, while those in the estrogen group received estrogen instead. During the experiment, the bone mineral density (BMD) of the whole body was observed dynamically, and local BMDs and biochemical indexes were measured after 3 months of treatment. Results Alkaline phosphatase (ALP) activity in the normal group was significantly lower than in the other groups. Tartrate-resistant acidic phosphatase 5b (TRAP5b)activity was elevated significantly, in the control and 0.14 mT groups compared with the normal group. After 2 months of treatment, whole body BMD was reduced significantly in the 0.14 mT group compared to the normal group. After 3 months of treatment, whole body BMD in the ovariectomized controls and the 0.14 mT group was reduced significantly compared to the normal group, but significantly elevated in the 0. 16 mT, 0.18 mT and estrogen groups when compared to the ovariectomized control group. At the end of 3 months of treatment, the trends in lumbar vertebral BMD were similar to those of the whole body BMD, with the femoral BMD in the ovariectomized group and the 0.14 mT group significantly lower than in the normal group, though the differences among the other groups were not statistically significant. Conclusions PEMF treatment at 50 Hz and 0.16 mT or 0.18 mT can promote bone formation. PEMFs at 50 Hz and 0.14 mT might stimulate bone resorption. An intensity-window effect exists in the action of PEMFs on bone metabolism in ovariectomized rats.

Background and purpose: Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) can be used for magnetic resonance imaging systemic examination, especially in examing the metastatic lesions, lymph node and bone diseases, and the imaging result is similar with PET. This study aimed to evaluate the application value of magnetic resonance DWIBS and positron emission tomography with computed tomography (PET/CT) on malignant metastatic diseases. Methods: Thirty-six patients confirmed with malignant tumors accompanying metastasis by the pathology of operation or biopsy underwent both DWIBS imaging and PET/CT, chi-square test and Kappa test were used for comparing the detection results of metastasis by these 2 imaging methods. Results:Among the 36 malignant tumor patients with 238 metastatic lesions, 218 (91.6%, 218/238) lesions in DWIBS and 209 (87.8%, 209/238) lesions in PET/CT were detected, with 200 lesions detected by the two methods simultaneously, and the concordance rate was 88.7%(211/238);but there was no statistical signiifcance between this two methods (χ2=1.843, P=0.157). Kappa test showed a fair concordance rate between DWIBS and PET/CT (P=0.000).There were different significance between DWIBS and PET/CT in detecting metastatic lesions of brain and bone (P=0.005 and 0.031);But there was no signiifcant differences (P=0.309 and 1.000) in detecting metastatic lesions of lymph nodes and liver. Conclusion:DWIBS could detect metastatic lesions effectively, and there is ifne consistency with PET/CT. DWIBS is more sensitive than PET/CT in detecting metastatic lesions of brain and bone, so DWIBS could be chosed for screening metastatic lesions according to the characteristics of different primary tumors.
