ABSTRACT
Objective To analyze the expression and predictive value of serum tumor markers spectrum and chemokine protein in lung cancer and predictive value.Methods One hundred and fifty patients with lung cancer were selected as the observation group and contemporaneous 150 individuals undergoing physical examination served the control group.The levels of ProGRP,CEA,SCC and Cyfra21-1 were measured by chemiluminescence microparticle immunoassay.The chemokine protein was determined by multiple immunofluorescent assay.Results The levels of CCL28,LIF,LIGHT and GRO in the observation group were significantly higher than those in the control group (P＜0.05).The levels of CCL28,LIF,LIGHT and GRO in the observation group were higher than those in the control group.The levels of CCL28,NAP-2 and MDC in the observation group were lower than those in the control group (P＜0.05).Conclusion The regular detection of serum tumor markers spectrum and chemokine protein can predict the treatment prognosis and evaluate the clinical curative effect.
ABSTRACT
Objective To investigate the myocardial protective effects of trimetazidine by observing the changes of peripheral B-type natriuretic peptide (BNP),cardiac troponin I (cTnI) level in patients undergoing off-pump coronary artery bypass graft (OPCAB), and the clinical significance of peripheral cTnI and BNP in cardiac surgery. Methods One hundred and three OPCAB patients were divided into trimetazidine group (52 cases) and control group (51 cases) by random digits table. The serum levels of BNP and cTnI preoperatively,postoperatively of 24 h, 72 h and 7 d were detected. Results The serum levels of BNP [(224.5 ± 12.0), (331.2 ±22.6), (82.4 ±3.3) ng/L] and cTnI [(0.21 ±0.04), (1.32 ±0.49), (0.26 ±0.04) μ g/L] in trimetazidine group were lower than those in control group [(294.7 ± 11.8 ), ( 383.9 ± 28.3 ),( 112.4 ± 12.5 ) ng/L and ( 1.20 ± 0. 13 ), (2.35 ± 0.54), (0.75 :± 0.21 ) μ g/L] postoperatively of 24 h, 72 h and 7 d (P＜ 0.05 ). The serum levels of BNP and cTnI increasedd at 24 h after operation. The peak level was found at 72 h and remained higher level until 7 d after operation. The baseline levels of BNP were positively correlated with cTnI (r = 0.635,P ＜ 0.05), but negatively correlated with left ventricular ejection fraction (LVEF) (r =-0.674,P ＜ 0.01 ). Conclusion Trimetazidine can obviously reduce serum levels of BNP and cTnI in patients undergoing OPCAB. So the united application of serum BNP and cTnI may be as a monitor marker to reflect the cardiac function in patients after OPCAB.
