Objective: To explore early diagnostic and resent prognostic assessment value of serum levels of ischemia-modified albumin (IMA) and cardiac troponin I (cTnI) for acute coronary syndrome (ACS).Methods: A total of 175 ACS patients were selected, including 73 cases with unstable angina pectoris (UAP), 61 cases with non-ST elevation myocardial infarction (NSTEMI) and 41 cases with ST elevation myocardial infarction (STEMI).According to chest pain-to-visit time, ACS patients were divided into <3h group (n=112) and 3~6h group (n=63);another 40 healthy subjects were selected simultaneously as healthy control group.Serum IMA and cTnI levels were compared among above groups and between patients suffering from major adverse cardiovascular events (MACE) within 30d or not in <3h group.Risk factors for MACE in <3h patients within 30d were screened.Results: Compared with healthy control group and UAP group, there were significant rise in serum levels of IMA[(16.78±4.25) μg/L, (35.16±8.32) μg/L vs.(49.76±9.29) μg/L, (52.07±11.34) μg/L], cTnI[(0.17±0.06) ng/ml, (0.15±0.06) ng/ml vs.(7.65±1.29) ng/ml, (8.83±1.40) ng/ml]in NSTEMI group and STEMI group, and IMA level in STEMI group was significantly higher than that of NSTEMI group, that of UAP group was significantly higher than that of healthy control group (P<0.05 or <0.01);serum IMA level of <3h group was significantly higher than those of 3~6h group and healthy control group, and cTnI level of <3h group was significantly lower than that of 3~6h group (P<0.01 all);serum levels of cTnI and IMA in patients suffering from MACE in <3h group were significantly higher than those of patients without MACE (P<0.01 both);multi-factor Logistic regression analysis indicated that elevated serum IMA level was an independent risk factor for MACE within 30d in ACS patients[OR=2.757,95%CI(2.084~4.705), P=0.001].Conclusion: The levels of cTnI and IMA significantly rise in ACS patients.IMA level possesses early diagnosis and recent prognosis evaluation value.

Objective To explore the application value of D-dimmer(DD),hs-CRP and homocysteine(Hcy) in postoperative condition monitoring in the patients with femoral neck fracture.Methods Forty cases of femoral neck fracture treated in our hospital were selected as the observation group and 40 patients with other fractures were selected as the control group.The observation group were given the surgical treatment,while the control group adopted the corresponding measures for conducting intervention according to the fracture situation.The DD,hs-CRP and Hcy levels were detected in the two groups.Then the detection results were compared between the two groups.Results The various indexes before treatment in the observation group were slightly higher than those in the control group without statistical difference(P>0.05).The levels of various indicators at postoperative 24,48 h in the observation group were significantly elevated,moreover the increase range at postoperative 24 h in the observation group was maximal,which was significantly higher than that in the control group(P<0.05).The positive rates of hs CRP,Hcy and DD in the observation group were 75.00%,77.50% and 60.00% respectively,while which in the control group were 0.00%,2.50% and 0.00%,the observation group was significantly higher than the control group (P<0.05).Conclusion Hs CRP,Hcy and DD can be used as the important indicators of condition monitoring for femoral neck fracture.
