ABSTRACT
ObjectiveTo investigate the expression of survivin,COX-2 and bcl-2 in non-Hodgkin lymphoma(NHL)and the significance and correlation between them.MethodsImmunohistochemistry MaxVision systems for survivin,COX-2 and bcl-2 were conducted on 44 NHL and 20 reactive lymphoid hyperplasia (RH).ResultsThe positive expression rates of survivin,COX-2,bcl-2 in NHL were 70.45 ％(31/44),68.18 ％ (30/44),63.64 ％ (28/44),respectively,and these in RH were 40.00 ％ (8/20),40.00 ％(8/20) and 20.00 ％ (4/20),respectively.There was positive correlation between the expression of COX-2 and survivin (r =0.306,P =0.043),survivin and bcl-2 protein (r =0.339,P =0.040) in NHL.ConclusionCOX-2,survivin,bcl-2 are highly expressed in NHL.To detect the expression of them has clinical value to diagnosis NHL and to estimate the malignant degree of lymphoma.There are a positive correlations between the expression of COX-2 and survivin protein,and between the expression of survivin and bcl-2 protein,which indicates that they may play a synergistic role in the occurrence and development of NHL.
ABSTRACT
Objective To investigate the sleep condition and its influence factors in old patients with hypertension. Methods A total of 100 old patients with hypertension were investigated by Pitts-burgh sleep quality index (PSQI) and serf-designed questionnaire of influence factors. Results 76 per-cents of the old patients with hypertension had sleep disorders.The total score of PSQI,sleep quality,time take to fall asleep,hours of sleep,sleep effficiency,sleep disorders,hypnotic drugs and every score of daytime dysfunction were significantly higher than domestic norm(P<0.01).Surroundings(strange circumstances or noisiness), physio-pathology (disease distress or high frequency of going to toilet during nighttime),psycho-logical situations(the fear to the disease or worrying about medical fees) and drags(use of diuretics or the adverse effects of some antihypertensive agents) were the important factors affecting sleep quality. Con-clusions Old patients with hypertension have poor sleep quality,which relates with multiple factors.Valid nursing interventions should be adopted in order to control the various factors which affect sleep quality to improve patients' sleep quality.
