Objective To explore the relation between serum nesfatin-1 ,tumor necrosis factor (TNF)-αand insulin resistance. Methods A total of 105 subjects were enrolled in this study and divided into two groups:patients with newly diagnosed type 2 diabetes mellitus (T2DM group,n= 64)and normal controls (NC group,n= 41). The fasting serum nesfatin-1 and TNF-αlevels were measured by enzyme-linked immuno sorbent assay (ELISA). FPG,HbA1 c,TG,TC,and FIns were also tested. BMI, HOMA-IR,HOMA-β,and ISI were calculated. Results Serum nesfatin-1 and TNF-αlevels were significantly higher in T2DM group than in NC group. Multiple linear regression analysis showed that the most significant influencing factors for nesfatin-1 were TNF-αand ISI(β= 0. 005、-6. 847,P<0. 05). The most significant influencing factors for TNF-αwas HbA1 c (β= 26. 652,P<0. 01). Conclusion Serum nesfatin-1 and TNF-αare significantly elevated in patients with newly diagnosed T2DM,which may influence the glucolipid metabolism through the signal pathway of insulin and play a role in the pathogenesis of T2DM and IR.

Objective To study the effect of down-rdgulation of EF-1 alpha gene in prostate cancer cell line DU-145 on cancer cell migration and invasion by using RNA interference technique. Methods The prostate cancer cell line DU-145 was divided into three groups: the control group (untransfected with siRNA), randomly control group (randomly transfected with siRNA) and experimental group (transfected with EF-1 alpha siRNA). Localization of EF-1 alpha and its relationship with F-actin in cytoplasm were analyzed by immunofluorescence technique. Cancer cell migration and invasion capability of DU145 cells were studied by transwell technique in these three groups. Results EF-1 alpha expression in DU145 cell line was down-regulated by using RNA interference technique. EF-1 alpha was localized in cytoplasm and co-located with F-actin. The down-regualtion of EF-1 alpha did not change the F-actin distribution in cytoplasm. The cell migration and invasion study showed that after seeding 20×104 DU145 cells into the upper chamber of transwall for 12 hours, the cells collected in the lower chambers were (10.6±1.0)×104 in control group, (11.2±0.8)×104 in randomly control group and (3.9±0.6)×104 in experimental group. Compared with controls, the cancer cell migration and invasion capability was significantly inhibited to only 37.1% (t= 13.9, P<0.05) after the specific down-regulation of EF-1 alpha expression in DU145 cells. Conclusions The down-regulation of EF-1 alpha expression has negative impacts on prostate cancer cell migration and invasion. EF-1 alpha plays important roles in prostate cancer local invasion.

Objective To investigate the effects of osteogenic growth peptide (OGP) in combination with extracorporeal shock waves (ESWs) on osteoblast proliferation.Methods Passaged cells were divided into four groups for different treatments:a control group,an OGP + ESW group,an ESW group,and an OGP group.After the respective treatments,the cells were cultured for 24 h,48 h and 72 h and counted using methylthiazdy tetrazolium (MTT) and an inverted fluorescence microscope. Immunohistochemical examination was used for detecting protein kinase A (PKA)activity,and a reverse transcription-polymerase chair reaction (RT-PCR) was used for examining PKA mRNA expression at 24 and 48 hours.Results Cell counting revealed that cell proliferation in the OGP + ESW,ESW and OGP groups was significantly promoted compared with the control group.Cell proliferation was greatest in the OGP + ESW group.The immunohistochemical examination showed positive staining intensities in the OGP + ESW,ESW and OGP groups significantly higher than in the control group.The positive staining intensity in the OGP + ESW group was again the highest.PKA activity was also significantly higher in the OGP + ESW,ESW and OGP groups than in the control group with the level in the OGP + ESW group the highest.Conclusion OGP in combination with ESW has a synergistic effect in stimulating osteoblast proliferation and growth.

Objective To study the elongation factor 1α(EF-1α) gene functions in prostate cancer cell line DU145 in the aspects of cell proliferation and clone formation by using the RNA interference technique. Methods DU145 cell lines were divided into control group, transfection control group transfected with scramble siRNA and experimental group transfected with EF-1α siRNA. After transfecting EF-1α siRNA into DU145 cell line, the down-regulation of EF-la expression in DU145 cell line was confirmed by Western blotting and immunofluorescence staining. Then, the cell proliferation and clone formation assays were carried on in these 3 groups of DU145 cells. Results Compared with controls, the specific down-regulation of EF-1α expression was achieved in experimental group only. Compared with control group, after the down-regualtion of EF-1α in DU145 cell line, the cell proliferation rate decreased from day 4 to day 7 after transfection by 45. 9%, 53. 5% , 35. 3% and 38. 1% , respectively(P<0. 05). The clone formation number in experimental group decreased by 67.0% (P<0. 01). Conclusions The down-regulation of EF-1α has a negative impact on prostate cancer cell proliferation and clone formation. EF-1α might be an appropiate targeting gene in prostate cancer targeting therapy.

BACKGROUND:Percutaneous kyphoplasty for the treatment of vertebral compression fractures has gained good clinical results and it is characterized as smal trauma, less bleeding and very low rate of complications. The vast majority of elderly patients can tolerate it, but this method cannot prevent fracture replase in the elderly. OBJECTIVE:To evaluate clinical outcomes of percutaneous kyphoplasty combined with anti-osteoporosis drug for the treatment of acute osteoporotic vertebral compression fractures METHODS:According to strict inclusion and exclusion criteria, 137 patients, including 26 males and 111 females, mean age of (75.55±6.96) years, with a total of 198 acute osteoporotic vertebral compression fractures treated by kyphoplasty that involves injection of polymethyl methacrylate cement under radiologic control into a treated vertebral body were conducted in this study. Al patients were asked to take anti-osteoporosis drugs for 3 post-treatment months. The primary outcomes were visual analogue scale, ertebral restoring rate, Oswestry disability index, Cobb angle at different time (pre-operation, 1 week and 3 months after operation). In addition, the rate of complications and the replase rate of vertebral compression fractures after operation were recorded. RESULTS AND CONCLUSION:There were significant differences in the mean visual analog scale scores, vertebral restoring rate, Oswestry disability index, Cobb angle at pre-procedure and post-procedure (at 1 week and 3 months) (P<0.001). In addition, the rate of postoperative complications was 0.7%and there were no vertebral compression fractures during 3-month fol ow-up period. Our study suggests that percutaneous kyphoplasty combined with anti-osteoporosis drug for the treatment of acute osteoporotic vertebral compression fractures can gain good clinical results.

Objective To investigate the neuroprotection of delayed treatment of thoracic acute spinal cord injury with recombinant human erythropoietin (rhEPO) in rat model of compressive injury. Methods Sixteen adult male Sprague-Dawley rats were randomly divided into two groups: control group (compressive injury group) and experimental group (rhEPO group), In the compressive injury group,the animals recived 0.9% saline treatment at 2 h, day 1 and day 3 after the injury, while in the rhEPO group, rhEPO (3 000 U/kg) was given to rats at 2 h, day 1 and day 3 after the injury. All the rats were observed in 4 days after the injury. The primary outcomes were evaluated by BBB scale, apoptotic index, inflammatory index and electron microscopy. Results Delayed treatment of thoracic acute spinal cord injury with rhEPO could reduce apoptosis, regulate inflammation, improve motor function and promote regeneration of the spinal cord. Conclusion Our study suggests that delayed treatment of thoracic spinal cord compressive injury with rhEPO could exert neuroprotection.
