Objective To analyze the blood of patients with hepatitis B cirrhosis complicated with iron deficiency anemia(IDA).Methods The 100 cases with hepatitis B cirrhosis complicated with IDA and hepatitis B cirrhosis complicated with non-iron deficiency anemia (NIDA) were recruited in our hospital from December 2013 to May 2015,and were divided into observation group (50 cases) and control group(50 cases) according to whether complicated with IDA.The liver function,blood routine,liver cirrhosis patients with coagulation test and measurement of the platelet parameters of two groups of patients were detected and analyzed.Results After treatment,no statistically significant difference were observed the levels of albumin,bilirubin,bile acid and alkaline phosphatase between two groups (P>0.05).The levels of alanine amino transferase (ALT),gamma glutamyltransferase (GGT) in the observation group were significantly higher than those in the control group(P<0.05).The hemoglobin,serum ferritin (SF),mean corpuscular volume (MCV),mean corpuscular hemoglobin (MCH) values in the observation group were lower than those in the control group,while level of folic acid was significantly higher than that of the control group(P<0.05).There was no significant difference on the red blood cell count (RBC) between two groups (P>0.05).The prothrombin time (PT),International normalized ratio (INR),activated partial thromboplastin time (APTT),thrombin time (TT) of observation group were higher than the control group(P<0.05);while the levels of fibrinogen (FIB),platelet count (Plt) were significantly lower than those of control group(P<0.05).There was no significant difference in platelet distribution width (PDW) between the two groups (P>0.05).Conclusion The detection of blood in patients with hepatitis B cirrhosis complicated with IDA is of great significance in the evaluation of the degree of liver damage and the diagnosis of the disease,which is worthy of clinical application in the future.
