Objective To analyze the levels of serum lipoprotein (a)[Lp(a)]and homocysteine (CHY)in type 2 diabetes mellitus (T2DM)patients and todetermine the relationship between them and diabetic insulin resistance.Methods A total of 108 patients with T2DM and 50 healthy volunteers (control group)were studied.T2DM group according to the presence of kidney disease complications could be divided into simple diabetes group (SDM)in 48 patients with diabetic nephropathy (DN)group of 60 cases.Collected patients general data and determined two groups of glycosylated hemoglobin (HbA1c), low density lipoprotein (LDL),urea nitrogen (BUN),serum creatinine (SCr),urinary inhibition C (CysC),Lp(a)and HCY levels;Compared differences between groups and how they related to T2DM kidney disease,and the relationship between in-sulin resistance.Results ①Compared between three groups only the weight (NC group 60.1±10.34 kg,SDM group 67.2 ±11.38 kg,DN group 68.8±1.35 kg),the difference was statistically significant (F=0.457,P=0.035).②compared be-tween the three groups,the levels of HbA1c (F=3.421,P=0.013),LDL-C (F=2.963,P=0.041),BUN (F=4.637,P=0.031),SCr (F=2.369,P=0.024),CysC (F=3.697,P=0.011),Lp(a)(F=1.236,P=0.021),HCY (F=4.317,P=0.027)were increased significantly.③FPG,FINS and HOMA-IR in SDM group were 5.99±0.94 mmol/L,61.11±28.46 pmol/L and 2.93±1.97 respectively,FPG,FINS and HOMA-IR in DN group were 9.01±2.23 mmol/L,98.56±62.14 pmol/L and 4.34±2.74 respectively.Compared between the two groups,FPG (t=0.47,P=0.017),FINS (t=0.55,P=0.039),HOMA-IR (t=0.69,P=0.024)differences were statistical significance.④The Lp(a),HCY were significantly pos-itive correlation with HOMA-IR (r=0.761,P=0.044;r=0.840,P=0.021).Conclusion Lp(a)and HCY levels in serum associated with diabetic nephropathy,and insulin resistance.And the detection of serum Lp(a)and HCY has important sig-nificance for early detection of diabetic nephropathy.

Objective Understanding of red blood cell distribution width (RDW-CV),blood homocysteine (HCY),lipoprotein a [LP(a)] a merger with high blood pressure and high blood,coronary heart disease (CHD) relevance and explore its clinical application value in CHD.Methods 563 cases of patients with high blood pressure were enrolled,which divided into 62 cases of primary hypertension,501 cases of hypertension combined with coronary heart disease,according to the results of coronary angiography.141 normal cases were chosen as control group.Compared the three groups of RDW-CV,HCY and LP (a) level,the group of coronary artery disease was divided into Ⅰ,Ⅱ,Ⅲ and Ⅳ,and compared the RDW-CV level of each group,and the correlation between RDW and cardiac function was analyzed.Results ①Heart disease groups RDW-CV,LP (a) and HCY (13.25 ± 1.22％,17.82 ± 8.36 μmol/L,172.05 ± 122.32 mg/L) were higher than blood pressure groups (12.98 ± 0.57 ％,14.35 ± 6.36 μ mol/L,124.49 ± 75.88 mg/L) and normal control group (11.41 ± 2.85 ％,11.41 ± 2.85 μmol/L,71.07±27.55 mg/L,P＜0.05).②RDW-CV and HCY were positively correlated with the mental function classification (r=0.461,0.1970;P=0.000,0.032).③The area under the ROC curve was the order of the diagnostic value:HCY ＞LP(a) ＞RDW-CV.LP(a) sensitivity was 82.5 ％ and specificity was 31.7 ％.RDW-CV sensitivity was 48.8 ％ and specificity was 22.2 ％.Conclusion High levels of RDW-CV,HCY,and LP(a) were closely related to the occurrence of coronary heart disease;RDW-CV and HCY were related to the severity of coronary heart disease and cardiac function,and could be a potential biomarker for the development of cardiac function of coronary heart disease.
