Objective To explore the effect of high-fat diet(HFD) on redox states of duodenum and calcium absorption in mice,and to analyze the relation between them.Method Fifty C57BL/6 male mice were randomly assigned to five groups.The control group consumed an ordinary diet(0.6% Ca,w/w),and other four groups were fed with HFD(19.64%lard,0.6% Ca),HFD plus 0.1% lipoid acid(LA),HFD with calcium supplement(1.6%Ca) and HFD with 1.6% Ca and 0.1% LA supplement.Calcium apparent absorption was measured by mineral balance study after feeding for 8 w.Plasma and duodenum levels of ROS,SOD,CAT,MDA,GSH/GSSG,and T-AOC were measured to evaluate the antioxidant status.Results HFD induced oxidative stress of duodenum and decrease of intestinal calcium absorption in mice.There were positive correlations between calcium apparent absorption with GSH/GSSG(r=0.801,P

Objective To investigate the changes in femoral gene expression profiles in C57BL/6 mice fed high-fat diet (HFD) via clustering analysis of DNA microarray.Method Sixteen male C57BL/6 mice (4w old) were randomly assigned to two groups,8 in each,after 4-d ordinary diet for adaptation.The control group was fed with an ordinary diet,and the HFD group with HFD(19.5% lard).All mice were sacrificed at the end of 12w and the femoral gene expression was detected by oligonucleotide microarray analysis with Affymetrix Gene Chip Mouse U430A.DAVID,an online tool,was used for clustering analysis on femoral gene expression.Results Longtime administration of HFD caused femoral gene expressed differences related to cation ion channel,transcription regulation and signal transduction,bone mineralization,phosphate metabolic process regulation,and collagen synthesis.Conclusion Longtime intake of HFD will change the expression of numerous bone metabolism-related genes in bone of mice,and then inhibit bone formation.

AIM:To investigate the serum antibody of aquaporin 4 ( AQP4 - Ab ) in positive expression rate and the significance in patients with neuritis.
●METHODS: A total of 98 cases ( 128 eyes ) of patients with optic neuritis were studied to detect the patient′s serum AQP4-Ab positive rate of antinuclear antibodies ( ANAs) from Jan. 2012 to Dec. 2015 in ophthalmology center of our hospital. According to the expression of AQP4 - Ab group, the best corrected visual acuity between the two groups, peripapillary nerve fiber layer thickness (pRNFL), the volume of the macula, macular RNFL ( mRNFL ) , macular core layer volume ( mlNL ) measurement were compared.
●RESULTS:Ninety-eight patients (128 eyes) with optic neuritis cases diagnosed through examination revealed AQP4-Ab positive in 22 patients ( 22%) , negative in 76 patients ( 78%) , ANAs positive in 21 patients ( 21%) , negative 77 patients ( 79%) . Optic neuritis patients with serum AQP4 - Ab positive rate and ANAs positive significant correlation ( r = 0. 707, P < 0. 05 ). After examination revealed AQP4-Ab patients and negative-positive patients with best corrected visual acuity difference was not statistically significance (P>0. 05). After inspection found pRNFL, macular volume measured value AQP4 - Ab positive patients were significantly less than the negative patients, the differences were statistically significant (P<0. 05). AQP4-Ab positive patients and negative patients the mRNFL, mlNL measured values were not significantly different (P>0. 05).
●CONCLUSION:AQP4-Ab and ANAs expression in optic neuritis patients is a significant correlation. AQP4-Ab positive patients with optic neuritis pRNFL thinning of macular volume are decreased compared with negative patients.

Objective:To study the anti-proliferation effects of a heat shock protein 90(Hsp90) inhibitor,17-allylamino-17-demethoxygeldanamycin(17-AAG),on a human breast cancer cell line,SKBr3,and related mechanism.Methods:MTT assay was used to detect the growth inhibition of SKBr3 cells.Cell cycle and apoptosis were analyzed by flow cytometry.Alteration of human epidermal growth factor receptor 2(HER2) in SKBr3 cells being treated with 17-AAG were measured by immunohistochemistry.Results:17-AAG significantly inhibited growth of SKBr3 cells in vitro in a dose-dependent manner with an IC_(50) value at 3.09 ?g/ml.Under concentrations of 0,0.625,1.250,2.500,5.000 and 10.000(?g/ml,)the percentages of cell apoptosis were(1.03?0.08)%,(3.68?0.67)%,(7.06?1.12)%,(11.23?1.36)%,(20.32?1.98)%,and(31.65?2.96)%;the percentages of cells at G_(0)/G_(l) phase were 58.61%,54.34%,49.55%,43.73%,35.52%,and 27.46%;the percentages of cells at S phase were 29.57%,25.21%,19.65%,22.98%,19.71%,and 15.46%;the percentages of cells at G_(2) /M phase were 11.82%,20.45%,30.18%,33.29%,44.77%,and 57.08%,respectively.The level of HER2 expression in SKBr3 cells being treated with 17-AAG,compared to that in control cells,was reduced significantly.Conclusion:17-AAG can inhibit the growth of human breast cancer cell and enhance its apoptosis.It may be a promising anti-tumor drug.

AIM: To confirm the effects of capillary endothelium injury in the lung with ischemia reperfusion. METHODS: The rabbits pulmonary models of ischemia reperfusion (I-R)injury were established. Plasma nitric oxide and endothelin levels, arterial oxygen tension and wet/dry weight ratios were determined in different periods in control and I-R groups, and the pulmonary ultrastructure abnormities were analyzed under electromicroscope. RESULTS: The plasma levels of NO and ET-1 in I-R animals increased significantly ,compared with those in sham treated control groups. The level of ET-1 had significantly negative correlation with PaO 2 and positive correlation with the value of the wet/dry weight ratios. The swelling and karyopyknosis of capillary endothelium in the lung with I-R groups were observed in ischemia periods. The injuries of endotheliums and typeⅠandⅡ alveolar cells in 0 5 h of reperfusion were more severe than those in ischemia time, and the injuries began to repair in 2 h of reperfusion time. CONCLUSION: In the I-R group, pulmonary capillary endothelium have been injuried, which may play a prominent role in I-R injury and dysfunction of the lung.

The heat shock protein ClpB is a member of the Clp family and functions as molecular chaperones. ClpB is related to the acquired thermotolerance in organisms. A cDNA of 3144 bp was screened out of a tomato cDNA library. The polypeptide deduced from the longest ORF contains 980 amino acid residues, and was classified into HSP100/ClpB family based on the result of molecular phylogenesis analysis. Thus it was named as LeHSP110/ClpB according to its calculated molecular weight. LeHSP110/ClpB was characteristic of heat-inducibility but no constitutive expression, and was demonstrated to locate in chloroplastic stroma. An antisense cDNA fragment of LeHsp110/ClpB under the control of CaMV 35S promoter was introduced into tomato by Agrobacterium tumefactions-mediated method. At high temperature, the mRNA levels of LeHsp110/ClpB in antisense transgenic plants were lower than those in control plants. The PS II of transgenic plants is more sensitive to high temperature than that of control plants according to data of Fv/Fm. These results clearly showed that HSP110/ClpB plays an important role in thermotolerance of high plants.

Low frequency sensorineural deafness is a common subtype of idiopathic sudden deafness. Certain patients suffered recurrent attacks without vertigo, much alike Meniere's disease. Few of them developed into definite Meniere's disease during long-term follow-up in many clinical studies. Although the pathophysiology of recurrent low frequency deafness is yet unknown, the desease is considered associated with early state of endolymphatic hydrops or migraine. Otologists shall be aware of its clinical course and careful explanation is necessary at time of initial informed consent.
