Objective To observe the effect of rosiglitazone on the concentration of interlukin (IL)-6 and IL-10 in lung tissues of diabetic rats.Methods The experimental diabetic rats were yielded by injecting streptozotocin(STZ) and feeding with high fat and high glucose food.We observed lung morphology in control group,diabetes mellitus(DM) group,and rosiglitazone group at 10 week and 20 week respectively under light microscope.Alteration of IL-6 and IL-10 in lung was measured by immunohistochemistry.Results The optical density values of IL-6 in the control group,the DM group and the roggerosiglitazone treatment group were 0.15 ±0.01,0.16 ±0.01;0.22 ±0.02,0.31 ±0.04;0.22 ±0.03,and 0.20 ±0.02 at 10 week and 20 week respectively (Fwithin =216.89,P ＜ 0.01 ; Fbetween =342.62,P ＜ 0.01 ; Finteraction =341.51,P ＜ 0.01).Any two groups had significant difference(P ＜ 0.05) except the comparison of the IL-6 values at 10 week and 20 week in the control group (P ＞ 0.05).The absorbance values of IL-10 in the three groups were 0.13 ± 0.01,0.15 ±0.02;0.20 ±0.01,0.21 ±0.01;0.20 ±0.02,and 0.17 ±0.01 at 10 week and 20 week respectively (Fwithin =14.612,P ＜0.01 ;Fbetween =909.19,P ＜0.01 ;Finteraction =210.55,P ＜0.01).Any two groups had significant difference(P ＜0.05) except the comparison of the IL-6 values at 10 week and 20 week in the control group.Conclusion The elevated levels of IL-6 and IL-10 in lung tissue of dibtetic rats might be related to the inflammation of lung tissues.Rosiglitazone may alleviate lung inflammation by regulating the levels of IL-6 and IL-10.

Objective To study that Geranylgeranylacetone(GA) induce the expression of heat shock protein 70 expression in hippocampus of Alzheimer's model rats and its effect on learning and memory ability in the model rats induced by Aβ1-42 injection into hippocampus.Method 72 health SD rats were randomly divided into GGA group,model group was injected with Aβ1-42 and control group was injected with normal saline into hippocampus.Y maze test was used to detect the learning and memory ability of the rats at the 7th,14th and 21st day after injection into hippocampus separately.HSP70 expression in hippocampus tissues were detected by RT-PCR and western-blot as soon as Y maze test has been finished.Result The learning and memory ability of the rats in model group decreased significantly at the 14th and 21st day after injection than those in control group(P<0.05),but not too much changed in GGA group(P<0.05).HSP70 expres- sions in hippocampus tissues in model group decreased gradually after injection Aβ1-42,but increased in GGA group at the 7th,14th and 21st day after injection.Conclusion GGA can induce the expression of HSP70 in hippocarnpus of Alzheimer's model rats and meliorate the neuron impairment as well as the learning and memory ability of the rats.

OBJECTIVE:To study the effects of simvastatin on oxidative stress and cell apoptosis in aged mice with myocardi-al ischemia-reperfusion (IR). METHODS:Aged mice were randomly divided into sham operation group (phosphate buffer solu-tion),model group(phosphate buffer solution)and simvastatin low-dose,medium-dose and high-dose groups(2.5,5 and 20 mg/kg) with 14 mice in each group. Those groups were given relevant medicine intraperitoneally before modeling for 7 d,once a day. IR model was induced in those groups except for sham operation group. The area ratio of myocardial infarction,myocardial cell apop-tosis rate,activity of myocardial tissue apoptosis gene Caspase-3,the protein expression of Bax and Bcl-2,Akt phosphorylation, serum concent of MDA and activity of SOD were all detected. RESULTS:Compared with sham operation group,the area ratio of myocardial infarction,myocardial cell apoptosis rate,Caspase-3 activity,the protein expression of Bax and MDA content were all increased in model group,while the protein expression of Bcl-2,Akt phosphorylation and SOD activity were decreased(P<0.01). Compared with model group,the area ratio of myocardial infarction,myocardial apoptosis rate,Caspase-3 activity,the protein ex-pression of Bax and MDA content were all decreased in simvastatin high-dose group,while the protein expression of Bcl-2,Akt phosphorylation and SOD activity were increased (P<0.01). There was no statistical significance in above indexes in simvastatin low-dose and medium-dose groups (P>0.05). CONCLUSIONS:Simvastatin can relieve myocardial IR injury in aged mice,and the mechanism of which may be associated with inhibiting myocardial cell apoptosis and the generation of oxidative stress.

OBJECTIVE: To analyze the impact of GBZ 49-2014 Diagnosis of Occupational Noise-induced Deafness and GBZ49-2007 Diagnostic Criteria of Occupational Noise-induced Deafness on the diagnosis of occupational noise-induced deafness( ONID). METHODS: A total of 84 individuals,who were workers exposed to noise and diagnosed as observation subjects by GBZ 49-2007 were selected as the subjects of study by judgment sampling. They were diagnosed based on the criteria of GBZ 49-2014 and GBZ 49-2007. The impact of different diagnostic audiometry,different age and gender correction methods and the inclusion of a weighting of 0. 1 high-frequency 4. 0 k Hz hearing threshold of GBZ 49-2014 on the diagnosis of ONID was analyzed. RESULTS: The binaural high frequency threshold average( BHFTA) calculated by GBZ 49-2014 were lower than that of GBZ 49-2007 [( 52. 1 ± 10. 3) vs( 52. 8 ± 10. 1) d B,P < 0. 05 ],but monaural threshold of weighted value( MTWV) of the good ear calculated by GBZ 49-2014 were higher than speech frequency threshold average( SPTA) of the good ear of GBZ 49-2007 [( 23. 2 ± 4. 1) vs( 19. 3 ± 4. 8) d B,P < 0. 01]. All of the 84 patients had BHFTA ≥40 d B and SPTA < 26 d B when diagnosed by GBZ 49-2007,and could not be diagnosed as ONID. A total of33. 3% patients had BHFTA ≥40 d B and MTWV ≥26 d B when diagnosed by GBZ 49-2014 which could be diagnosed as mild ONID. The detection rate of ONID was 21. 4% to 34. 5%( P < 0. 01) when the threshold of 4. 0 k Hz was used as the weighting diagnostic threshold of hearing in the case of using different diagnostic audiograms and different age and sex correction methods. CONCLUSION: A high-frequency hearing threshold of 4. 0 k Hz with a weighting of 0. 1 was included in GBZ 49-2014 as a diagnostic threshold,which reduced the diagnostic threshold of ONID.
