ABSTRACT
Objective To investigate the depression status and its influencing factors in the patients with uremia before and after the first time hemodialysis.Methods A total of 177 patients with uremia conducted the questionnaire investigation by using the Hamilton Depression Scale and self-made general information questionnaire.Meanwhile,the laboratory indexes were detected and analyzed.Results At one week before dialysis,35% of the patients had different degrees of depression symptoms,11.9% of the patients had depressive symptoms at 1 week after dialysis;the depression scores before and after dialysis were(14.96 ± 8.37) points and(6.52 ± 3.81)points respectively,the difference was statistically significant(t=16.267,P<0.01).The depression score had statistical difference between the patients with complications and patients without complications(t= -2.528,P=0.013);while the depression scores had no statistical difference among the patients with different sexes,ages,cultural levels,types of original dis-eases,whether smoking and drinking(P<0.01).The Spearman correlation analysis showed that the levels of GLU,Cr and BUN were positively correlated with the depression score,while the levels of TC and Alb were negatively correlated with the depression score,the difference was statistically significant(P< 0.01).Conclusion The evaluation of depression status in hemodialysis pa-tients should be emphasized.
ABSTRACT
40 patients,20 males and 20 females,with 52 miniscrews were included.The concentration of IL-1β,IL-6 and IL-8 in the gingival crevicular fluid around the miniscrews were measured.The results showed that the concentrations of IL-1β,IL-6 and IL-8 increased during orthodintic tooth movement(P ＜0.05),indicating that orthodontic force had an effect on the cytokines around the miniscrews,which may be related to orthodontic bone resorption.
ABSTRACT
Objective To explore high concentrations of urea-induced human brain microvascular endothelial cell line( HBMECs) to produce inflammatory cytokines and possible mechanism .Methods HBMECs were incubated in high concentrations of urea or mannitol ( as osmotic control ) for 3,6,12 and 24 hours.Expression of TNF-αand iNOS was observed by immunofluorescence .Western blot analysis was employed to assess the protein expressions of TNF-α, iNOS, COX-2, NF-κB/P65 and p-P65.NO concentration was determined by a commercial NO assay kit .

ABSTRACT
ObjectiveTo evaluate the feasibility and value of mini-clinical evaluation exercise (Mini-CEX) in clinical neurology practice.MethodsNinety-four interns were randomly divided into observation group and control group,students in control group were teached and managed in accordance with existing management while those in observation group were evaluated by teachers after the 1 st,2nd and 3rd week.At the end of clinical practice,all the students( including students in control group and observation group)were cross assessed by teachers based on the methods mentioned above.Results The time to complete the assessment was about 25 - 40 min.The scores of nervous system examination at the end of the training were significant different between observation group and control group and the scores of diagnosis and treatment on the basis of examination were also significant different between observation group and control group ( P ＜ 0.05 ).ConclusionThe Mini-CEX assessment and feedback to promote teaching effect is feasible in the practice process of neurology,it can make up for the deficiency of current examination.
ABSTRACT
Objective To observe the post-systolic shortening (PSS) during isovolumic relaxation phase and its clinical significance in regional myocardium in chronic heart failure (CHF) patients.MethodsLeft ventricular regional myocardium movement in 60 CHF patients (CHF group) and 30 healthy volunteers (control group) were assessed with tissue velocity imaging (TVI). QLAB software was used to measure the systolic peak velocity (V_s), regional systolic time (T_s), post-systolic shortening velocity (V_(pss)) and post-systolic shortening time (T_(pss)) at the basal and middle levels of left ventricle. Results In CHF patients, the rate of isovolumic relaxation phase PSS was 34.44% both in basal and mid segments, the rate of pathological PSS was 29.44% and 29.72%, respectively. The rate of isovolumic relaxation phase PSS in control group was 26.11% and 20.56%, respectively; none pathological PPS occured. Compared with the physiological PSS of control group, the pathological PSS of CHF group had a higher peak velocity and a longer time (P<0.05). Conclusion The pathological PSS of CHF patients has high peak velocity and long duration, which may be one of the causes leading to the asynchronous movement of left ventricle in CHF.
ABSTRACT
Objective To assess the short-term effect of cardiac resynchronization therapy (CRT) by speckle tracking strain imaging(STI). Methods Sixteen chronic heart failure patients(CHF) with CRT were enrolled. The time to peak systolic longitudinal strain and the time to peak systolic radial strain were derived from the LV apical views, and the time to peak systolic circumferential strain was derived from the parasternal short axis. The standard deviation for time to peak longitudinal, radial and circumferential strain in the 18 segments (LS-SD18, RS-SD18, CS-SD18) and the maximal temporal difference of any two segments(LS-dif, RS-dif, CS-dif) were calculated as a strain-derived dyssynchrony index. The difference of LS-SDIS, RS-SD18, CS-SD18 between 1 month,3 months after CRT and baseline (△LS-SD18, △RS-SD18, △CS-SD18) was calculated. The correlation between △LS-SD18,ARS-SD18,△CS-SD18 and the reduction of end-systolic volume at follow-up(△ESV%) were analyzed. Results The LS-SD18, RS-SD18,CS-SD18 and RS-dif were decreased significantly 1 month,3 months after CRT.△RS-SD18 was correlated with △ESV% 3 months after CRT(r = 0. 694). Conclusions The strain-derived dyssynchrony index is great significient for short-term effect of CRT.
ABSTRACT
Objective To evaluate the tissue motion tracking of mitral annular displaeement(TMAD) method in the assessment of short-term effect of cardiac resynchronization therapy (CRT). Methods Twenty six chronic heart failure (CHF) patients with CRT were detected by TMAD. The maximal displacement of the six points of mitral annulus(DS), the standard deviation of the time to regional peak systolie displacement of the six points (Td-sd) and the maximal temporal difference of any two points(Tds-diff) were compared before and one month after CRT. And the correlation between mean displacement and left ventricular ejection fraetion(LVEF),left ventricular end systolic volume(LVESV), fraction area change (FAC) was analyzed. Results Compared with the pre-operatively, the displacement and the mean displaeement of the six points of mitral annulus were significantly increased(P<0.01),Tds diff and Td-sd were decreased(P<0.05) one month after CRT. TMAD correlated with LVEF,LVESV and FAC (r =0.419, r = 0.529, r = 0.567, P <0.05) one month after CRT. Conclusions TMAD is a new technology to evaluate the short-term effect of CRT.
ABSTRACT
To evaluate the role of color Doppler flow imaging in the portal vein chemotherapy by ultrasound guided percutaneous transhepatic portal injection, the blood supply of liver tumor and portal hemodynamics were studied in 15 patients with primary hepatic carcinoma and one patient with secondary hepatic carcinoma. The continuous wave in the lesion and forward continuous wave in the portal vein seen by pulsed Doppler in nine cases, were indications for this therapeutic method. The distribution of the drugs in the liver could be observed by color Doppler flow imaging when injection was being done. The therapeutic efficacy of portal vein chemotherapy in liver tumor may be evaluated by color Doppler folw imaging and puncture biopsy.
