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 clinicl bacteria distribution and the drug resistance.METHODS The biochemical and serologic tests were used to detect the susceptibility of bacterium to antimicrobials.RESULTS The positive rate was 44.87%,bacteria distributed mainly in sputum,urine and secretion.Pseudomonas aeruginosa,Escherichia coli,Staphylococcus epidermidis,Klebsiella pneumoniae and Acinetobacter often appeared.The drug resistance rate of MRSA and MRCNS was higher than MSSA and MSCNS's.The drug sensitive rate of Enterococcus faecium was less than E faecalis's.Bacteria of Enterobacteriaceae were sensitive to the drug of imipenem.The test rate for E.coli and K.pneumoniae which released ESBLs was 23.9% and 25.4%,respectively.P.aeruginosa possessed high resistance to all drugs.CONCLUSIONS The rate of Gram-positive cocci in all specimen is rising,the drug resistance is rather related with the broad use of antimicrobials.

OBJECTIVETo analyze the changes of patients with type 2 diabetes in different stages in glucagon (GC) and free fatty acid (FFA) in fasting, OGT and L-Arg experiments, and discusses the role of pancreatic alphabeta cells in diabetes pathogenesis by studying the relations among indexes such as glucagon (GC), free fatty acid (FFA) and blood glucose (BG), insulin, insulin homeostasis model (HOMA) and glucose metabolism hormone secretion curve, in order to provide theoretical basis for the treatment of diabetes.

METHODStudy objects were divided into the T2DM group (45 cases), the IGT group (28 cases) and the NGT group (30 cases) for an OGTT experiment and then an L-Arg experiment on the next day. Under the fasting state, their blood glucose (FBG), insulin (F), glucagon (FGC), free fatty acid (FFA) were detected to calculate HOMA-beta, insulin sensitivity index (ISI) and HOMA-IR of different groups. Meanwhile, efforts were made to calculate different time quantum detected in OGTT and L-Arg experiments and area under the curve AUC(BG), AUC(INS) and AUC(GC).

RESULTObvious overall differences were observed in FFA and FGC of the three groups. FGC of each group was negatively correlated with HOMA-beta and ISI. Among all of the 103 study objects, FGC was positively correlated with FBG and HOMA-IR and negatively correlated with HOMA-beta and ISI, with no correlation with FINS; FFA was positively correlated with FBG, HOMA-IR and negatively correlated with FINS, HOMA-beta, ISI. FGC and FFA were positively correlated in the T2DM group and the IGT group, but with no statistical correlation in the NGT group. The sequence of the three study objects was T2DM > IGR > NGT in AUC(GC) in the OGTT experiment and T2DM > IGR > NGT in in AUC(GC) in the L-Arg experiment, with the significant positive correlation between AUC(GC) and AUC(BG) and significant negative correlation with AUC(INS).

CONCLUSIONGlucagon and free fatty acid of T2DM and IGT patients increased, which was positively correlated with blood glucose and HOMA-IR and negatively correlated with INS, HOMA-beta and ISI. The increase in glucagons of T2DM and IGT patients indicated inappropriate secretion of pancreatic alphabeta cells among patients with type 2 diabetes.

Objective;To explore the relationship among parents' negative punishment,children's self-concept,and children's social behaviors.Methods;Data were collected from questionnaires given to a sample of 612 children from primary and secondary schools and their parents.Results;The structural equation modeling results showed parents' negative punishments could influence children's social behaviors directly and indirectly.In the indirect approach,through the mediating role of children's self-concept,parents' negative punishments could make a negative role on children's pro-social and aggressive behaviors,and a positive role on children's withdrawn behavior.In the direct approach,parents' negative punishments could make a positive effect on children's pro-social,aggressive and withdrawn behavior directly.Conclusion;Children's self-concept plays a mediating role between the relationship of parents' negative punishments and children's social behaviors.

OTX1 gene is one of the pivotal transcriptional factors involved in the neurogenesis.In order to overexpress the OTX1 gene in distinct cell types and find out its contribution to the proliferation and differentiation of stem cells in vitro,OTX1 cDNA was subcloned into lentiviral vectors.The resulting constructions pDUETOTX1,pDUETGFPOTX1 and pDUETGFP were packaged in 293 cells producing viral particles to transduce 293T cells,SY5Y cells,mouse embryonic stem cells and E15 neural stem cells.It was proved that the transferred OTX1 gene was located in the nuclei of the transduced cells in stead of plasma.Lentivirus is an ideal vector delivering gene to different cells.The overexpression of OTX1 in transduced 293T cells were validated by Western blot and immunofluorescence.

Objective:To remove murine embryonic stem cells(mESC)from the differentiating cell culture and purify the differentiated cells by Magnetic Activated Cell Sorting(MACS).Methods:Neural differentiation of mESC was induced by a 5-stage method.The specific cell surface marker,SSEA-1,was used to identify ES cells in the differentiating cells.The optimal dilutions of mouse anti mouse SSEA-1 IgM primary antibody and FITC conjugated goat anti mouse secondary antibody were determined before the flow cytometry test.The incubation time and incubation temperature of primary antibody were all optimized to make the cytometry test accurate.After the optimization,stage 4 cells were dissociated into single cell suspension,incubated with antibody of SSEA-1 and microbeads conjugated goat anti mouse IgM,and then sorted through the magnetic field.The rate of SSEA-1 positive cells in pre-and post-separation groups was assessed by flow cytometry,and the viability of cells was evaluated by trypan blue staining counting under light microscopy.Results:The proportion of SSEA-1 positive cells in the separated cells can be reduced from(7.19?1.36)% to(1.34?0.80)%.The survival rate of sorted cells was more than 92%,similar to that of pre-separation cells.Conclusions:The MACS system we used can effectively remove mESC from the differentiated cells.The sorted cells will be well provided for the subsequent studies about transplantation therapy.
