RESUMO
Objective To investigate the clinical application value of strong ion gap(SIG)generated by the third generation equa-tion following pH and the anion gap(AG)in critically ill patients.Methods On the basis of the determination results of blood gas and blood biochemistry,the equation in the Stewart-Figge methodology was adopted to calculate SIG.Results (1)There were sta-tistically significant differences in K+ ,Na+ ,HCO3 - ,AG,pH,PO4 3 - ,ALB,SIG and Cr between the critical illness groups and the control group(P <0.05).(2)The SIG mean value ratio the death group to non-death group was 3.04,the difference was the big-gest,P <0.05,AG and Cr took the second place.Conclusion SIG as a new indicator in combination with other biochemical and blood gas indicators,such as the HCO3 - ,AG,pH,PO4 3 - ,Cr and lactic acid can reflect the situation of the acid-base disorders in critically ill patients and plays a strong indicative role in predicting the disease development trends.
RESUMO
Objective To explore the pathogenic mechanism associated with insulin resistance(IR) and adiponetin(APN) abnormality in carotid atherosclerosis(CAS) patients complicated with nonalcoholic fatty liver disease(NAFLD),and to study their relationships with traditional Chinese medical(TCM) syndrome types.Methods Seventy-four CAS patients complicated with NAFLD(group A) and 25 CAS patients(group B) were enrolled into the study.Fasting blood glucose(FBG),fasting serum insulin(FI),and serum APN levels were measured.IR and APN were evaluated by the homeostasis assessment(HOMA) method.HOMA-IR and APN in group A were compared with those in group B,and bivariate correlation analysis was made between the two indexes in group A.The relationship of HOMA-IR and APN with TCM syndrome types was analyzed in group A.Results (1) HOMA-IR was obviously increased,and APN was obviously decreased in group A(P
