ABSTRACT
Objective To observe the effects of ketamine on the behavior and indoleamine 2,3-dioxygenase (IDO ) signaling pathway in the rats with pain and depression comorbidity. Methods Twenty-four male adult SD rats,aged 2 months,weighing 200-250 g,were randomized into three groups:control group (group S),saline group (group N)and ketamine group (group K), eight in each group.CFA (50 μl)was injected into the right tibiotarsal joint cavity to establish the model of pain and depression comorbidity in the groups N and K,whereas saline (50 μl)was injected in the group S.The mechanical withdrawal threshold (MWT)and the immobility time were measured 1,7,and 14 days after the CFA injection.After the behavioral tests 14 days after the CFA injection, saline (1 ml)was intraperitoneal administrated in the group N and ketamine 20 mg/kg (1 ml)was in-traperitoneal administrated in the group K 14 days after CFA injection.The MWT and immobility time were measured 1 h after administration in the three groups to evaluate the behavioral changes. Then,the hippocampus,prefrontal cortex,cingulated gyrus and plasma were harvested to determine the levels of IL-6 and IDO using an enzyme-linked immunosorbent assay after the behavioral tests. Results Compared with the group S,the MWT was decreased and the immobility time was signifi-cantly increased in the group N and group K (P <0.05).Compared with the group N,the MWT was increased (P <0.05),the immobility time was decreased (P <0.05),and the levels of IL-6 and IDO in the hippocampus,prefrontal cortex and cingulated gyrus were significantly decreased in the group K (P < 0.05 ).Conclusion Ketamine can effectively treat pain and depression comorbidity,which may be attributed to the inhibition of IDO signaling pathway in different brain regions of rats.
ABSTRACT
Objective To build position system based on a large ship ocean nursing needs.Methods Two rounds of expert consultation were carried out through the literature material method,field survey,comparative research method,and Delphi method to build nursing station system of the large ship.Results The expert authority coefficient was 0.81.Two rounds of expert coordination coefficients were 0.55,0.52.The nursing position system contained three parts:level Ⅰ position,level Ⅱ position and the post job responsibilities.Conclusions The system contains 21 stations,the expert opinions are concentrated with high credibility,it can provide certain theoretical support for the nursing personnel selection,training,and ship jobs management of large ship.
ABSTRACT
@#Objective To observe the effect of early multidisciplinary rehabilitation therapy on stroke patients.Methods 80 cases of acute stroke were randomly divided into the rehabilitation group (n=40) and control group (n=40). All patients of two groups were treated with routine treatment, and those of the rehabilitation group were added with early multidisciplinary rehabilitation therapy. The degrees of clinical neural function defect, motor function and activities of daily living (ADL) of all patients in two groups were assessed by the clinical neural function defect assessment (NIHSS), Fugl-Meyer Assessment (FMA) and Barthel Index (BI) before and one month after treatment.Results The scores of NIHSS, FMA and BI of patients in two groups were not different before treatment ( P>0.05). After treatment, the scores of patients of the rehabilitation group were significantly higher than that of the control group ( P<0.01).Conclusion Early multidisciplinary rehabilitation therapy can improve the neural function, ADL and raise the quality of life of post stoke patients.
