Objective To describe the public discrimination against patients with mental disorders,and to explore its influencing factors.Methods This study was a descriptive study.A total of 1 378 public received the survey.The survey instruments include general information questionnaire and assessment scale of discrimination against patients with mental disorders.Results The scores of the scale of discrimination against patients with mental disorders was (2.07± 0.61).The score of risk dimension was higher(2.17±0.87),and the ability dimension was lower(1.65±0.64).Multiple regression analysis showed that factors influencing the total score of the scale were type of investigation objects,age,gender,educational background,contact degree and life connection degree to the patients with mental disorders.Conclusion Because psychiatric patients had perceived stigma,and social demographic factors,clinical factors,social and psychological factors could influence their perceived stigma,so the nurse should pay more attention to discrimination against patients,and reduce or eliminate the discrimination toward the patients,then promote recovery of the patients.

ABSTRACT:Objective For preparation of vascularized islets , to isolate and culture human adipose derived stem cells , investigate the role of adipose derived stem cells (ADSCs ) in promoting the proliferation and vascularization of human umbilical vein endothelial cells (HUVECs ) co‐cultured in vitro , and explore its mechanism .Methods ADSCs and HUVECs were isolated by collagenase digestion method ,then cultured ,and identified by morphology ,immunofluorescence or multi‐directional differentiation .The co‐culture system of ADSCs and HUVECs was established , HUVECs cultured alone were set up for control group . The proliferation , vascularization and concentration of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (b‐FGF)in the supernatant were compared between the two groups .Results The third generational ADSCs had uniform long spindle fiberous morphology and multi‐directional differentiational function . Immunofluorescence test of surface antigens on ADSCs revealed CD44/CD49d (+ ) ,CD31/CD34 (-) ,on HUVECs CD31/vWF (+ ) . High vascular density was found when co‐cultured in Matrigel of ADSCs and HUVECs than alone of HUVECs .Growth curve shown at days 3 , 4 and 5 of the logarithmic phase , HUVECs count in co‐culture group of ADSCs and HUVECs was (4 .52 ± 0 .31) × 104 ,(7 .18 ± 0 .45) × 104 ,and (8 .23 ± 0 .36) × 104 under indirect co‐culture condition , while that in individual HUVECs group was (2 .71 ± 0 .25) × 104 ,(4 .87 ± 0 .26) × 104 ,and (6 .86 ± 0 .33) × 104 ( P<0 .01) .Population doubling time of HUVECs was shorter in co‐culture group than in individual group .Also ,the OD value of HUVECs was higher in co‐culture group than in individual group when cultured at days 1 ,3 ,5 and 7 ( P<0 .01) .When cultured at days 3 ,7 and 13 ,the concentration of VEGF and b‐FGF in the supernatant was higher in co‐culture group than in individual group ( P< 0 .01 ) . Conclusion ADSCs can promote the proliferation and vascularization of HUVECs in vitro co‐culture conditions by secreting or increasing the HUVECs secretion of VEGF and b‐FGF .

Objective To determine the expression of glial fibrillary acidic protein(GFAP) and vascular endothelial growth factor(VEGF) in the hippocampus of rats with Alzheimer's disease(AD), and to determine the effect of butylphthalide on them and its significance. Methods Sixty male adult rats were randomly divided into a model group, a Butylphthalide group, and a control group. AD models were established by injecting β-amyloid protein 1-42 into the hippocampus of rats. Sixty days later,the rats were sacrificed and both sides of the hippocampus were sectioned for immunohistochemistry. Results Positive cells of GFAP in the hippocampus of the model group increased and the expression of VEGF decreased statistically, compared with the control group(P<0.01). The positive cells of GFAP in the hippocampus of the butylphthalide group decreased and the expression of VEGF increased significantly, compared with the model group(P<0.05). Conclusion Butylphthalide may protect the neuron-vascular unit of the hippocampus of Alzheimer model rats by inhibiting the expression of GFAP and increasing the expression of VEGF.

Objective To investigate the prevalence of undernutrition, nutritional risks, and the application of nutrition supports in different hospitals in Shandong province, and to estimate the related complication rate.Methods Totally 2792 patients from different hospitals in Shandong were enrolled, and their nutritional risks were assessed using Nutritional Risk Screening (NRS) 2002. The application of nutritional supports, the length of hospital stay, and the incidences of infectious and non-infectious complications were documented. Results The incidences of undernutrition and nutritional risk among patients in large hospitals were significantly higher than those in middle and small hospitals (5.6%, 1.6%, 2. 7%; 27.3%, 15.4%, 18.3%; P =0. 000). The overall rate of nutritional support was 43. 60%, and there were significant difference among patients in different hospitals (51.5 %, 30. 8 %, 20.9 %, P = 0. 000). Parenteral nutrition was most widely applied. Among the 483 patients in large hospitals, the incidence of complication in patients with nutritional risks was significantly higher than those without nutritional risks (31.3% versus 13.7%, P =0. 000). Of the "with nutritional risk" patients, the infectious complications were significantly lower in the nutritional support group (P = 0. 000). Of the patients without nutritional risks, there was no statistical difference between the nutritional support group and the non-support group. (P ＞ 0. 05). Conclusions NRS 2002 is a useful tool for the assessment of nutritional status among inpatients. Proper nutritional support can reduce the incidence of complications for patients with nutritional risks.
