Objective To evaluate the serum Level of B-natriure peptide(BNP)in elderly patients with Left Ventricular dysfunction and to determine the correlation between the BNPand hemodynamic Variable.Methods According to New York Heart Association(NYHA)class.51 patients with Left Ventricular dysfunction and 28 without Left Ventricular dysfunction(control group)were measured.BNP Levels were obtained,Left ventricular ejection fraction(LVEF)was assessed by echocardiography,center vein pressure(CVP)was determined in NYHA Class Ⅲ-Ⅳ groups.Results BNP were (39.32?5.51)ng/L in control group,respectively(265.94?63.13)ng/L in NYHA ClassⅡgroup(n=18),(569.93?109.17)ng/L 、CVP was(9.67?1.23)cmH_2O in NYHA class Ⅲ group,(2 764.33?1 020.53)、CVP was(19.61?4.57)cmH_2O in NYHA class Ⅳ.The difference of BNP and CVP in groups were scegnificant(all P

OBJECTIVETo examine serum levels of sICAM-1 from normal controls and patients with thyroid diseases (simple goitre, Graves' disease or Hashimoto's thyroiditis) with (125)I-sICAM-1 RIA established in our lab.

METHODSUsing (125)I-sICAM-1 RIA, serum sICAM-1 levels of 400 healthy individuals as the normal group and 1020 patients with simple goitre (SG), Graves' disease (GD) or Hashimoto's thyroiditis (HT) were examined for a comporative chinical study.

RESULTSThe serum level of sICAM-1 (x +/- s) in the normal group was 168.43 +/- 36.23 micro g/L. There was no significant difference between the normal and SG groups (P > 0.05), whereas the serum levels of sICAM-1 in autoimmune thyroid diseases (GD or HT) were higher than those in the normal or SG groups (P < 0.05, respectively). After GD patients received one of three medical treatments, their serum sICAM-1 levels decreased (P < 0.05). After GD patients were treated and their thyroid function decreased to normal, their serum sICAM-1 levels were lower than those in relapsed GD patients (P < 0.05).

CONCLUSIONSsICAM-1 RIA can be used to examine autoimmune thyroid diseases. Serum levels of sICAM-1 can be used as a parameter in diagnosing autoimmune thyroid disease and in evaluating the effects of therapy, drug administration or relapse in GD.
