[Objective] To investigate the effects of aerobic exercise on osteoporosis in the elderly.[Methods]Sixty elderly were divided into two groups:control group(n=30)without conscious and regular exercise and experimental group(n=30)with aerobic exercise.After 12 months,bone mineral density in lateral lumbar spine 2~4(L2~4),left side of femoral neck(L-FN),left side of greater trochanter(L-TR)and wards area were measured for by dual energy X-ray absorptiometry(DEXA)for the statistical analysis.[Results]The bone-mass-loss after the experiment was obviously lower than before;bone mineral density(BMD)of control group was lower than experimental group in the four parts.The difference(P

Objective To investigate metabolic characteristics and insulin resistance in newly diagnosed type 2 diabetes pa-tients with nonalcoholic fatty liver disease .Methods Two hundred patients with newly diagnosed type 2 diabetes mellitus including 140 with nonalcoholic fatty liver disease (NAFLD) (NAFLD group) and 60 without NAFLD (non-NAFLD group) were recruited. Metabolic characteristic were measured and recorded .homeostasis model assessment insulin resistance ( HOMA-IR) index and HOMA-C were used to assess insulin resistance .Results were compared between two groups .Results Compared with non-NAFLD group, body mass index (BMI), fasting blood glucose (FBG),alanine aminotransferase (ALT),gamma-glutamyl transferase (GGT), uric acid ( UA) , triglyceride ( TG) , low density lipoprotein cholesterol ( LDL-C) ,fasting insulin ( FINS) , fasting C peptide ( FCP) , gly-cated hemoglobin a1c (HbA1c), HOMA-IR, and HOMA-C were significantly higher in the NAFLD group ( P <0.05).Logistics re-gression analysis showed that BMI , TG, GGT, and UA were risk factots for NAFLD ( P <0.05, OR =1.82, 1.53, 1.37, and 1.09 ) .Conclusions Compared patients without NAFLD , newly diagnosed type 2 diabetes patients with NAFLD present more meta-bolic disturbance, and severely insulin resistance.Obesity and the increased level of postprandial UA , triglyceridemia, and GGT might increase the risk of NAFLD in the patients with newly diagnosed type 2 diabetes mellitus .

Objective To investigate the cytoprotection of curcumin against rotenone(Ro)-induced injury and the molecular mechanisms underlying in PC12 cells.Methods The insulted model of PC12 cells was established with Ro.Cell viability was determined using MTT reduction assay.The content of reactive oxygen species(ROS)was determined by the method of DCFH-DA staining.Chromatometry was used to measure the total activity of SOD,DCFH-DA staining to measure the level of intracellular ROS,and flow cytometry to assay the apoptosis rate.Results 0.5 and 1.0 μmol/L curcumin significantly decreased the inhibitory rate of Ro on the growth of PC12 cells for 24 h as compared with the Ro group(P＜0.01).0.5 and 1.0 μmol/L curcumin significantly ameliorated the changes in morphology of PC12 cells,increased the activities of intracellular SOD as compared with the Ro group(P＜0.05),decreased the production of intracellular ROS and inhibited the apoptosis of PC12 cells induced by Ro for 24 h as compared with Ro group(P＜0.01).Conclusion Curcumin can resist Ro-induced cytotoxicity probably by the mechanism of scavenging intracellular ROS and increasing the activity of antioxidase.

Objective To explore the electronystagmography (ENG) changes and their clinical significance in aged patients with vertebro-basilar insufficiency (VBI). Methods Sixty aged patients with VBI were selected as experimental group for testing of visuo-oculomotor system reaction, spontaneous nystagmus, caloric test and positional nystagmus. Forty normal aged persons as control group. Results In the experimental group, there were 11 cases (18.3%) who had spontaneous nystagmus and 46 cases (76.6%) with positional nystagmus. The positional nystagmus intension in those patients was 7.76?6.05?/s, which was much higher compared to the control group (P

Objective To investigate the inhibitory effects of exogenous WAF 1 S gene on human laryngeal cancer Hep 2 cell line, and to explore the potential use of WAF 1 S in gene therapy for laryngeal cancer. Methods A eukaryotic expression vector containing 2 1kb human full length WAF 1 S cDNA was transfected into human laryngeal cancer Hep 2 cell line by using lipofectamine. Expression of exogenous WAF 1 S gene was detected by dot blot hybridization. By using Western blot and confocal microscope, expression of p21 protein was quantitatively analyzed in situ . The growth state of transfected Hep 2 cell was determined by flow cytometry and MTT. Results It was found by dot blot hybridization that WAF 1 S gene could express in Hep 2 cell. The expression of the exogenous p21 gene in Hep 2 cells was markedly higher than that in the control group. It was confirmed with flow cytometry that WAF 1 S gene could induce apoptosis of laryngeal cancer Hep 2 cell line, and the progression of cell cycle was arrested at G 1 phase. Conclusion Laryngeal cancer cells could be arrested at G 1 /S phase and the growth of the cells could be significantly suppressed by exogenous WAF 1 S gene

Background and purpose:The cinobufacini injection is a traditional antitumor drug.However,its mechanism iS still unclear.The purpose of this study was to observe the effect of cinobufacini injections in DNA TOPO Ⅰ of human hepatocellular carcinoma HcpG-2 cells.Methods:The cells that were proliferated were assessed by MTT assay.Cell cycles were shown through FCM.TOPO Ⅰ mRNA expression was analyzed through RT-PCR.The activity of TOPO Ⅰ was measured by TOPO Ⅰ mediated super coiled PHR322 relaxation.Supercoiled PBR322 was also used to determine the direct DNA breakages.Results:Cinobufacini injections significantly inhibited HepG-2 cells proliferation in ways that were dependent on dosages and time.Induced tumor cells arrest at the S-phase.TOPO ⅠmRNA expression decreased in a manner that was dependent on dosages which inhibited the TOPO Ⅰ mediated DNA relaxations.However,the cinobufacini injections could not directly induce DNA breakage at any concentration.Conclusion:Cinobufacini injections can inhibit human hepatocellular carcinoma HepG-2 cells proliferation.The regulation of topoisomerase Ⅰ activity and mRNA expression may be one of the mechanisms that causes the cinobufacini injection to contribute against tumor.
