RESUMEN
Objective@#To investigate the relationship between hope, mental suffering and quality of life in radiotherapy patients with cervical cancer, to provide the basis for the cancer patient′s psychological intervention.@*Methods@#A cross-sectional study of 120 cases of radiotherapy cervical cancer patients was conducted, using the psychological distress thermometer, Herth Hope Scale, Life Quality Measurement Scale for patients with cervical cancer to evaluate patients′ hope, quality of life and psychological distress.@*Results@#Radiotherapy cervical cancer patients′ psychological distress and hope were negatively correlated (r=-0.385, P <0.01), psychological distress and quality of life were negatively correlated (r=-0.602, P <0.01), hope and quality of life were positive correlation (r=0.711, P <0.01). Patients′ hope played partially mediated effect between psychological distress and quality of life, emotional status, functional status, played fully mediated effect between psychological distress and social family status. The Mediated effect sizes were 35.9%, 36.3%, 55.9% and 100.0%.@*Conclusions@#Psychological distress has not only a direct negative effect on the quality of life of cancer patients, but also an indirect negative effect through hope. During the Medical care, we should accurately assess of patient's psychological distress and hope, and take measures to help improve patients' hope and alleviate psychological distress, so as to improve patients′ quality of life.

OBJECTIVE: To establish a PC12 cell line with stable expression of human apolipoprotein E( ApoE4) gene by transfection with a lentiviral vector carrying human ApoE4 gene and to investigate the effect of maltol aluminum on the viability of transfected PC12 cells. METHODS: The lentiviral vector carrying human ApoE4 gene was transfected into PC12 cells. PC12 cells with overexpression of ApoE4 gene and negative control vector were obtained after puromycin screening.The mRNA relative expression of R-Apo E and( or) H-Apo E-FLAG of cells in PC12,PC12-NC and PC12-ApoE4 groups were detected by real-time fluorescent quantitative polymerase chain reaction,and the effect of cell construction was identified. PC12-ApoE4 cells and PC12 cells were exposed to maltol aluminum solution at concentrations of 0. 00,100. 00,200. 00 and 400. 00 μmol/L respectively for 24 hours,and cell viability was detected by Cell Counting Kit-8( CCK-8)assay. RESULTS: PC12-ApoE4 and PC12-NC cells under the fluorescence microscope showed fluorescence expression,suggesting that transfection was successful. The expression of PC12 cells showed no fluorescence. The relative expression of H-Apo E-FLAG gene mRNA( the median amount) of PC12-ApoE4 cells was 148. 74,which was higher than the R-Apo E gene in PC12 cells( 1. 00) and PC12-NC cells( 1. 01)( P < 0. 01). After exposure to maltol aluminum,the cell survival rates in terms of the main effect and interaction effect of dose and cell type were statistically significant( P < 0. 01),among them,the cell viabilities were decreased in the concentration range of 0. 00-400. 00 μmol/L with the dose of maltol aluminum exposure increased,showing dose-effect relationship( P < 0. 01). CONCLUSION: The cell line stably expressed human ApoE4 gene was constructed successfully. There was interaction between the effects of maltol aluminum and ApoE4 gene on the survival rate of PC12 cells,and ApoE4 gene could enhance the cytotoxicity of maltol aluminum on PC12 cells.

Objective To observe the application of the mini-mental status examination (MMSE)cognitive assessment in the patients with brain glioma before and after surgery. Methods Using MMSE,36 pastients with primary brain glioma were subjected to the cognitive assessment before surgery, after surgery,and 3 monthsr after surgery. Results The quantitative cognitive assessments with MMSE before surgery revealed the hidden cognitive dysfunction patients.The quantitative cognitive assessments after surgery showed that surgeons might need to protect the non-function area and to form the idea of cognitive function in patients with glioma.Conclusion MMSE assessment is a simple,understandably,and convenient method having good compliance of patient. It may be effectively used to assess cognitive impairment for patients with glioma and worth being studied continuously and used widely in the clinic practice.
RESUMEN
Type 1 diabetes is pathologically characterized by autoimmune insulitis-related islet β-cell destruction.Although intensive insulin therapy for patients with type 1 diabetes can correct hyperglycemia,this therapy does not effectively prevent diabetes-related cardiovascular complications.Hence,preservation of natural β-cell function is critical for the prevention of diabetes-related complications.Receut studies have shown that autologous hematopoietic stem cell transplantation ( A HSCT) is a new promising approach for the treatment of type 1 diabetes by reeonstitution of immunotolerance and preservation of islet β-cell function.Here we introduce the key results of a clinical trial ( NCT 01341899,ClinicalTrials.gov) performed in Chinese type 1 diabetes patients ( most of them with diabetic ketoacidosis at onset ) and discuss the potential mechanisms underlying the action of HSCT and its prospects in the clinical management of type 1 diabetes.
RESUMEN
Objective To explore the effects of high glucose on glucose transport activity, and phosphorylationandexpressionofinsulinsignalingproteins in primary cultured rat adipocytes. Methods Isolated rat adipocytes were cultured at different glucose concentrations (5, 10, 15, 25 mmol/L) for 24 h. Then the glucose uptake, the phosphorylations of insulin receptor (IR), insulin receptor substrate (IRS) 1 and 2 and protein kinase B (PKB) as well as the protein expressions of IRS1, IRS2, p85 subunit of phosphatitylinositol 3 kinase (p85) and PKB were measured. Results These adipocytes treated with different high glucose showed the impairment of the basal and insulin induced increase in glucose uptake and significant decrease of IR, IRS1 and PKB phosphorylations as well as IRS1 protein expression, but up regulation of IRS2 protein expression. p85 and PKB contents and IRS2 phosphorylation were unaffected. Conclusion The exposure to high glucose inhibits glucose uptake and induces insulin resistance in adipocyte. The mechanism may be involved in affecting the multiple step phosphorylations and the expressions of insulin signaling proteins.
