Objective: To investigate the protective effect of deferoxamine preconditioning against hypoxia injury in astrocytes and the underlying mechanisms. Methods: Astrocytes were cultured under ischemia stress, which was mimicked by oxygen and glucose deprivation (OGD) with deferoxamine. Astrocytes were divided into three groups: normally cultured group; Deferoxamine pretreated group: astrocytes were pretreated with Deferoxamine and then treated with Deferoxamine OGD; and OGD group; astrocytes were treated with Deferoxamine OGD. The cell viability examination, the ratio of condensed nuclei, and the morphological changes were used to assess the protective effect of deferoxamine. The expression of HIF-1a and EPO protein and mRNA in astrocytes was examined by immunofluorescence staining and RT-PCR, respectively. Results: The morphology of AS in the deferoxamine pretreated group kept intact. AS viability in deferoxamine pretreated group was 58% of the normally cultured group, and that in the OGD group was 25% of the normally cultured group (P<0. 05). The ratio of condensed nuclei in deferoxamine pretreated group was 38% and that in OGD group was 30% (P<0. 05). Immunofluorescence staining found that expression HIF-1a, and EPO protein appeared in cultured astrocytes after deferoxamine pretreatment. RT-PCR confirmed that mRNA of HIF-1a and EPO was up-regulated after deferoxamine pretreatment. Conclusion: Deferoxamine preconditioning can protect the astrocytes from hypoxia damage, which is related to deferoxamine-induced increase of HIF-1a and EPO expression.

AIM: To investigate the difference of cognitive impairment and depression between age-related macular degeneration ( AMD ) group and the control group patients. ·METHODS: A prospective case-control study was performed from November 2014 to August 2016 in the hospital for AMD patients and sex-matched control group. The Mini-Mental State Examination ( MMSE) and the Geriatric Depression Scale ( GDS ) score of each patient were collected for statistical analyzing. ·RESULTS: There were total 84 cases ( 168 eyes ) included in the study. The difference of visual acuity between the two group was statistically significant ( F=8. 953, P=0. 004) by baseline data analyzing. There were no significant differences in MMSE scores between the two groups according to educational status ( P>0. 05 ) , while the prevalence of cognitive impairment in each group was statistically significant (x2 =4. 14, P=0. 042). The difference of GDS scores, prevalence of total and mild depression between two groups were both statistically significant (F=5. 852, P=0. 018; x2=6. 372, P=0. 012; x2 = 5. 674, P = 0. 017 ). However, there was no statistically significant difference in the prevalence of moderate to severe depression (x2=0. 672, P=0. 412). ·CONCLUSION: AMD patients have a higher prevalence of depression. Although MMSE score differences were not statistically significant in subgroup analysis by educational levels, AMD patients are more likely to have cognitive impairment overall.

Objective To investigate the distribution of pathogenic bacteria of vaginal discharge in bacterial vaginosis.Methods The results of bacterial culture and drug sensitive tests of vaginal discharge from patients with bacterial vaginosis were analyzed.Results The positive rate of bacteria culture of vaginal discharge was 79.3%(115/145).The dominant bacteria were staphylococcus epidermidis 27.0%(31/115),staphylococcus intermedius and staphylococcus aureus 13.0%(15/115),which were obviously higher than other germs.The drug sensitive tests showed that staphylococcus were relatively sensitive to vancomycin,fosfomycin,amikacin and rifampin.But the drug resistance to penicillin,tetracycline,erythromycin and oxacillin was the highest.Conclusion The kinds of pathogenic bacteria in vaginal discharge are various.The main bacterium is staphylococcus,and drug resistance is very severe.The isolation and drug sensitive test of pathogenic bacteria play an important role in diagnosis and treatment of gynecological disease.

OBJECTIVE: To investigate the application of autogenous cartilage transplantation in rhinoplasty. METHOD: We chose three kinds of treatment according to the shape of nasal tip and thickness of local soft tissue. Autogenous auricular cartilage transplantation combined with "L" type artificial prosthesis rhinoplasty was executed in 57 cases. Nasal alar cartilage transplantation combined with "L" type artificial prosthesis rhinoplasty was executed in 33 cases and septal cartilage transplantation combined with "willow leaf" type artificial prosthesis rhinoplasty was executed in 29 cases. RESULT: Improved nasal aesthetic effects were observed after operation in all of 119 cases, 64 cases were follow-up visited for 3 to 12 months. Both surgeons and patients were satisfied with the nasal shape. CONCLUSION Autogenous cartilage transplantation combining with artificial prosthesis rhinoplasty could effectively rebuild the nasorostral shape. We chose different kinds of cartilage according to the nasorostral condition. We can ensure that the whole nasal shape according to aesthetic requirement.
