Endothelial cells can be activated, and develop dysfunction and damage under the pathological state. Endothelial dysfunction plays a key role in the processes of cardio-cerebrovascular diseases, and can be detected in peripheral blood. The concentration of von Willebrand factor (vWF) predicts the risk of coronary heart disease and stroke; the concentration of soluble thrombomodulin is associated with the prognoses of coronary heart disease and stroke; soluble intercellular ashesion rnolecule-1 (ICAM-1) predicts the risks of carotid athero-sclerosis, coronary heart disease, peripheral arterial disease, and diabetes mellitus; the levels of plasma soluble E-selectin in patients with carotid atherosclerosis, coronary artery disease, and diabetes mellitus are increased; the increased endothelin-1 levels predicts the elevated risk of congestive heart failure. The injection of endothelial progenitor cells is promising to become a novel approach for the treatment of cardio-cerebrovascular diseases.

Objective To investigate if Carroll Upper Extremities Functional Test (UEFT) is a better rating scale for evaluating fine mo-tor function in children with cerebral palsy. Methods From January, 2011 to January, 2014, 104 children with cerebral palsy were divided in-to non-hemiplegic palsy group (n=76) and hemiplegic palsy group (n=28), they were assessed by two certified valuers in one week. Their fine motor function was evaluated with UEFT and the Gesell Developmental Scale. The scores of UEFT were compared respectively with the developmental age (DA) and developmental quotient (DQ) in fine motor domain of Gesell Developmental Scale. At the same time, the UEFT score of the affected limb was compared with of the unaffected limb in children with hemiplegic palsy. Results In the non-hemiplegic palsy group, the UEFT score strongly correlated with DA (r=0.752, P<0.001) and moderately correlated with DQ (r=0.456, P<0.001). In the hemiplegic palsy group, the UEFT score of the unaffected limb strongly correlated with DA (r=0.722, P<0.001), and a moderate correlation was found in the affected limb (r=0.591, P<0.001). The UEFT scores of both sides did not correlated with DQ (r<0.186, P>0.05). The UEFT score of unaffected limb was significantly higher than that of the affected limb (Z=-4.708, P<0.001). Conclusion Both of UEFT and the Ge-sell Developmental Scale could be used clinically in assessment of fine motor function in children with cerebral palsy. The UEFT was better in evaluating children with hemiplegic palsy.

Objective To discuss the effect of targeted information support on the sense of uncertainty and anxiety among patients treated with percutaneous coronary intervention and its instructive significance to nursing work.Methods We randomized 118 patients treated with percutaneous coronary intervention whose sense of uncertainty and anxiety were relative intensive into the test group and the control group with 59 cases in each group.We gave routine health instructions to the control group while targeted information support besides routine health instructions to the test group.We investigated the patients in two groups by Chinese version of uncertainty scale and State Anxiety Inventory at 4 time points,that is ,the first day in hospital,night before the operation,24 hours after the operation and 1 day before leaving hospital.Results The anxiety level and sense of uncertainty about illness decreased at the night before operation,24 hours after operation and 1 day after operation compared with the control group.The sense of uncertainty and anxiety level has statistical difference between whatever two adjacent time points except for anxiety level between the time points between the first day in hospital and before operation.Drop of sense of uncertainty at 24 hours after operation was significantly different between the two groups(P<0.01).Conclusion Supplying targeted information support could decrease the sense of uncertainty and anxiety among patients treated with percutaneous coronary intervention.

Objective To investigate effects of glucose on mesenchymal stem cells(MSCs) proliferation and the possible mechanism. Methods We evaluated the purity of MSCs,established different groups of glucose, detected proliferation by MTT, and analyzed cell cycle and apoptosis by a flow cytometry system. Results The purity of MSCs exceeded 90%.The positive rates of CD44, CD90, CD45, CD34 were 91.92%, 93.38%, 2.23%, 1.05% respectively.Glucose significantly affected MSCs proliferation(P=0.003):11 mmol/L glucose could promote MSCs proliferation, but 25 mmol/L glucose made this effect disappear. High glucose significantly increased the percent of S phase in cell cycle(P=0.002)and the rate of apoptosis(P=0.000). Conclusions Glucose has two-way regulation towards MSCs proliferation, and the balance between cell-cycle arrest and apoptosis could be responsible for this effects

Objective To evaluate the sterilizing efficiency ofabscrbable poly-L-lactide (PLLA) screws sterilized with ethylene oxide and 60Co-γ radial. Methods One group of PLLA screws was sterilized in the ethylene oxide sterilization ease. In order to eliminate the rudimental ethylene oxide, the sterilized screws was put in the air for five days. The other group of PLLA screws was sterilized with 60Co-γ radial with absorbable dose of 15 kGy. Then all sterilized screws were characterized. Results Compared with the primal bend intensity of the PLLA screws, the bend intensity of sterilized screws did not descend remarkably (P＞0.05). Compared with the primal molecular weight of the PLLA screws, the molecular weight of screws with 60Co-γ radiation sterilization re-markably decreased 11%. It indicated that the material had degraded. The molecular weight of screws with ethylene oxide sterilization ordy decreased 3%. It indicated that the material didn't degrade obviously. Conclusion Ethylene oxide sterilization is a better way for sterilizing absorbable PLLA screws.

Objective To investigate the correlation of nuclear factor‐κB (NF‐κB) with metabolic syndrome(MS). Methods A total of 240 subjects living in rural areas of Ningxia were enrolled in this study and divided into two groups :MS group (n= 120 ) and healthy control group (n= 120 ). The relationship of NF‐κB with MS was evaluated by t‐test ,partial correlation and conditional logistic regression analysis. Results Whole blood NF‐κB protein level was significantly lower in MS group than in control group [(352.31 ± 307.35) vs (441.00 ± 345.10) ng/L ,P<0.05]. Whole blood NF‐κB protein level was significantly lower in male ,Han nationality ,and 45~55 years old patients of MS group than in control group (P<0.05). Partial correlation analysis showed that NF‐κB was associated with BMI (β=-0.146 ,P=0.025) .Conditional logistic regression analysis showed that whole blood NF‐κB protein was a protective factor for MS (OR=0.91 ,95% CI:0.72~0.98 ,P<0.05). Conclusion The blood NF‐κB level is associated with MS.
