Results:There are 34.5%(19/55) patients admit under psychological stress during the treatment, which were affected by the tension from doctors’ consultation and the chemotherapy experience. Conclusion:Some patients were under psychological stress caused by the position immobility with thermoplastic sheet. Nursing intervention is necessary to improve, especially to the patients who show stress when consultation with doctors and who had chemotherapy experience.

Objective To seek the effect of SGK1 on the protection and prognosis of cerebral ischemia reperfusion. Methods Animal model of rats was used to construct them into experimental group(A)and control group(B). The impact of cerebral ischemia reperfusion on the hippocampus neuron cell apoptosis was simulated by making the overexpression of SGK1 and using PI3K inhibitors LY294002 to deal with animal models. Results The overexpression of SGK1 could reduce the neuron cell apoptosis caused by cerebral ischemia reperfusion to a certain extent,reverse the expressions of Cleaved aspas 3 protein,pro-apoptotic protein Bax and inhibitor of apoptoasis protein Bcl-2 through the PI3K/Akt-mediated signaling pathway. Conclusion SGK1 can protect the tissues with ischemia-reperfusion,which may provide the biological evidence for future clinical applications.

Objective To explore the relationship and clinical significance among glycosylated hemoglobin (HbA1c),fasting blood glucose (FPG),insulin (Ins),C peptide (CP)and urinary mirco-albumin (urine m-Alb)inpatients with type 2 diabetes melli-tus (T2DM).Methods A total of inpatients with type 2 diabetes were choose in this study and divided into mild diabetic group (HbA1c ≤ 9%)with 45 cases,severe diabetic group (HbA1c > 9%)with 44 cases.Twenty healthy persons were selected into control group.The levels of HbA1c,FPG,Ins,CP and m-Alb in urine of each group were detected and compared,the relationships of them were analyzed.Results There were significant differences on the levels of HbA1c,FPG,Ins,CP and m-Alb in urine of each group,and the former three indicators from low to high followed by the control group,the mild diabetic group,the severe diabetic group.There was no significant difference on the level of Ins between the control group and the severe diabetic group(P >0.05), but the level of Ins in the mild diabetic group was significant higher than that of the control group and the severe diabetes group (P <0.05).The CP level in the mild diabetic group was significant higher than that in the control group (P <0.05),and has a posi-tive correlation with the level HbA1c (r=0.427,P <0.05 ).The CP level in the severe diabetic group was significant lower than that in the control group,(P <0.05)and was negatively correlated with the level HbA1c (r=-0.415,P <0.05).Conclusion The joint detection of HbA1c,FPG,Ins,CP and urine m-Alb has positive significance to control type 2 diabetes,protect islet function and prevent diabetic nephropathy,CP is better than Ins on the assessment of the secretory function of islet,and CP might be in-volved in the occurrence and development of diabetic nephropathy.

Conclusion Health education based on mobile health education platform for patients after coronary stent implantation can effectively improve health behavior and self-efficacy,and it is worthy of clinical popularization.

AIM: To observe the changes of glutamate and calcium within the hippocampal microenvironment in mitochondrial stress.METHODS: A lateral hippocampus was microperfused with glutamate and calcium chloride solution by a kind of single-pumped push-pull perfusion system in Tree Shrews.At 24 h,the expression of cytochrome C(Cyt C)was observed by immunochemistry.Also,the hippocampus was removed,then mitochondria and cytoplasmic fragment were divided by low temperature centrifugation and the distribution of cytochrome C was assessed through Western blotting.The relative amounts of caspase-3 and caspase-9 mRNA were evaluated by real time fluorescence polymerase chain reaction.In the treated group,cyclosporin A(CsA,40 mg/kg) was intravascularly injected at 6 h after perfusion of glutamate-calcium chloride solutions into the hippocampus and inspected the above-mentioned items at 24 h.RESULTS: In the glutamate-calcium group,compared with the control group,cytochrome C immunoreactivity increased and the content of hippocampal mitochondrial cytochrome C decreased.Also,the cytochrome C was detected in cytosol.Cyclosporin A treatment at 6 h after microperfusion,the cytochrome C expression weakened and no Cyt C in cytosol fraction was observed.By real time PCR,in relation to the control group,the caspase-3 and caspase-9 mRNA was higher in the glutamate-calcium group.Cyclosporin A treatment cut down both caspase-3 and caspase-9 mRNA contents.CONCLUSION: The accumulation of glutamate and calcium may promote Cyt C release,caspase cascade activation and the mitochondrial stress.The neuroprotection of CsA may results from uniquely inhibiting the mitochondrial permeability transition pore,and preventing Cyt C release and caspase activation.

AIM: To observe the effect of platelet-activating factor (PAF) on cultured neuronal viability and glial fibrillary acidic protein (GFAP) expression in cultured astrocytes. METHODS: Neurons and astrocytes obtained from the brain cortex of the embryo and newborn mice respectively were cultured and purified, and they were divided into the control and experimental groups. PAF was added into the experimental groups at concentrations of 4, 8 and 16 ?mol/L. Each group was cultured for 4 h, 24 h and 72 h, respectively. MTT method and immunohistochemistry were used to observe the neuronal viability and GFAP expression in astrocytes, respectively. RESULTS: During different time after adding PAF at different concentrations into cultured neurons and astrocytes, respectively, neuronal viability declined, and the number of astrocytes decreased, but GFAP expression in survival astrocytes increased. The effects were shown to be in a concentration-dependent manner. CONCLUSION: PAF decreases the neuronal viability directly and influences the neuronal survival indirectly by astrocytes.
