ABSTRACT
Objective To investigate the clinical effect of low molecular weight heparin calcium (MvH) in the treatment of acute exacerbation of chronic obstructive pulmonary disease(AECOPD)complicated with pulmonary heart disease. Methods 128 AECOPD patients with pulmonary heart disease from January 2016 to December 2016 in our hospital were randomly divided into observation group and control group in equal number by random digit table with EXCEL2007. Apart from the basic treatment like anti infection,oxygen,expectorant,maintenance of water and electrolyte balance and cardiotonic treatment ,the observation group was treated with MvH. The two groups were compared in terms of pre-and post-ventricular end diastolic volume(EDV),end systolic volume(ESV),right ventricular ejection fraction(RVEF),pulmonary artery acceleration time(AT),arterial oxygen pressure(PaO2),arterial partial pressure of carbon dioxide(PaCO2),pH value,whole blood viscosity at low shear the whole blood viscosity at high shear rate,plasma viscosity,hematocrit,plasma D- dimer(D-D). Results After treatment,EDV and ESV of the observation group were significantly lower than the control group (P < 0.05)and RVEF and AT were higher than the control group(P < 0.05). PaCO2 was lower than that of the control group(P < 0.05). PaO2,pH values were higher than those of the control group(P < 0.05). After treatment,the whole blood viscosity,whole blood low shear viscosity at high shear rate,plasma viscosity,hematocrit, plasma level of D-D of the observation group were all lower than those of the control group (P < 0.05). Conclusion Subcutaneous injection with MvH to treat the patients with AECOPD complicated with pulmonary heart disease can improve the blood rheology and improve heart function and blood gas level.
ABSTRACT
Objective To investigate the diagnostic value of serum tumors M2 pyruvate kinase (TuM2-PK),carcino-embryonic antigen (CEA),CA199,CA724,CA125 and CA242 in colon cancer.Methods Serum levels of TuM2-PK,CEA,CA199,CA724,CA125 and CA242 in 231 patients with colon cancer,105 patients with colon benign lesion diseases and 166 normal controls were measured by the ELISA and electrochemiluminescence assays.The operation working characteristic curve (ROC) and the logistic regression-ROC were used to evaluate the diagnostic value of tumor markers for colon cancer individually and in combination.The models of logistic regression analysis and partial least-squares discriminant analysis (PLS-DA) were established to diagnose patients with colon cancer based on the optimal panel of serum tumor markers.Resalts Concentrations of serum TuM2-PK,CEA,CA199,CA125 and CA724 in the colon cancer group are higher than those in the colon benign diseases group and the normal controls (P＜0.05).The area under the operation working characteristic curve (AUC) of CA199 is the highest 0.79 [95％ confidence interval (95％CI),0.75-0.83] at the cutoff value of 69.5 U/L with 64.1％ of sensitivity and 89.7％ of specificity.The AUC of combined serum tumor markers based on logistic regression analysis is higher than those in individuals,of which serum (CEA+ CA199+TuM2-PK) is the optimal [AUC=0.89,95％ confidence interval(95％CI),0.86-0.92].The diagnostic accuracy of logistic analysis and PLS-DA model for colon cancer is 82.7％ and 77.5％,and for colon cancer is 93.7％ and 95.6％,respectively.Conclusion The combination of serum tumor markers CEA,CA199 and TuM2-PK is more suitable as a diagnostic model for the screening of colon cancer.
