ABSTRACT
Objective To analysis the health related quality of life (HRQOL)in emigrants with rheumatoid arthritis(RA) in Three‐Gorge Reservoir area ,and to study the influencing factors on HRQOL .Methods Self‐rating depression scale(SDS) was used to assess degree of depression in emigrants with rheumatoid arthritis in Three‐Gorge Reservoir area ,and SF‐36 scalec was used to assess the HRQOL of these patients .The one‐way ANOVA and stepwise regression analysis were used to study the influence fac‐tors of HRQOL .Results SDS scores showed that there were 110 peoples with depressive symptoms (67 .5% ) ,including mild de‐pression 58 cases(35 .6% ) ,moderate depression 39 cases(23 .9% ) ,severe depression 13 cases(8 .0% ) .Stepwise regression analysis showed that :SDS score ,DAS‐28 classification ,age ,sex ,treatment ,education ,occupation ,physical exercis ,economic income ,health insurance and alcohol consumption influenced the HRQOL scores of patients with IBS .DAS‐28 classification ,economic income , health insurance ,sex ,treatment were the main influencing factors ,with the unstandardized partial coefficients of -39 .211 ,31 .512 , 25 .866 ,-42 .348 ,-51 .235 .Conclusion Most of emigrants with RA in Three‐Gorge Reservoir area suffering from depressive symptoms ,and the HRQOL scores of them is not optimistic .The results suggested that more attention must be paid to the elderly , low‐income ,women ,low education ,DAS‐28 classification and no occupation .Quiting drinking ,receiving treatment ,psychological treatment ,strengthen exercise and expanding the scope of medical insurance all can improve patients′health related quality of life .
ABSTRACT
Objective To investigate the expressions of brain-derived nerve growth factor (BDNF) and growth-associated protein 43 (GAP-43) in the hypothalamus of rats inflicted with restraint stress and their relationship with behavioral changes.Methods Forty male SD rats were divided into control group,restraint stress 7-day group,restraint stress 14-day group,restraint stress 21-day group according to the random number table,with 10 rats per group.Behavior changes were observed by open-field test,serum levels of corticotrophin releasing hormone (CRH) by enzyme-linked immunosorbent assay,and expressions of BDNF and GAP-43 in the hypothalamus by western blotting.Results Restraint stress 7-day group exhibited increases in spanning lattice times (50.0 ± 7.0),standing times (11.4 ± 2.1)and modification times (11.2 ± 2.7) compared with all other groups (P ＜ 0.05).Restraint stress 14-day group and restraint stress 21-day group showed significant decreases in spanning lattice times (35.5 ±7.5,29.4 ± 6.8),standing times (7.8 ± 4.9,5.6 ± 3.9) and modification times (6.7 ± 2.9,4.4 ±2.6) compared with control group (42.6 ± 5.4,8.9 ± 4.3,and 7.9 ± 3.0) (P ＜ 0.05).Restraint 14-day and 21-day groups showed significant increases in serum CRH level [(750.73 ± 123.68) pg/ml and (793.06 ± 115.84)pg/ml] compared with that in restraint stress 7-day group [(500.48 ± 88.71)pg/ml,P ＜0.05],but all were lower than (336.72 ±45.34) pg/ml in control group (P ＜0.05).Levels of BDNF and GAP-43 in the hypothalamus were the lowest in control group (0.672 ± 0.185 and 0.694 ±0.253).However,restraint stress increased the expressions of BDNF and GAP-43 in the hypothalamus,with the highest level in restraint stress 21-day group (1.357 ± 0.524 and 1.486 ± 0.679) (P ＜ 0.05).Conclusion Restraim stress can up-regulate BDNF and GAP-43 proteins in the hypothalamus,and lead to plasticity changes that may relate to stress-related behavior.
