RESUMO
Objective To investigate the value of serum amyloid A (SAA) and retinol binding protein (RBP) in diagnosis of early type 2 diabetic kidney disease (DKD).Methods A total of 182 type 2 diabetic patients hospitalized in department of Endocrinology and Nephrology of Lianyungang Second People's Hospital from January to December 2017 were randomly collected as subjects.According to urinary albumincreatinine ratio (UACR),all subjects were divided into three groups of normal albuminuria group (NA,60 cases),microalbuminuria group (MA,63 cases) and clinical proteinuria (CP,59 cases).In the same period,60 healthy persons were selected as normal control (NC).The levels of serum SAA and RBP were detected by automatic biochemical analyzer.Receiver operating curve (ROC) was used to analysis the diagnostic efficiency of DKD and the risk factors of DKD were further estimated.Results The levels of SAA were (6.88±2.82) and (37.21±20.58) mg/L in control group and case group.And levels of serum SAA in the NA group,MA group and CP group were (16.33±5.98),(40.97± 15.62),(54.43±22.91) mg/L respectively.The levels of RBP were (37.56± 10.51) and (69.26±21.23) mg/L in control group and case group.And levels of RBP in the NA group,MA group and CP group were (52.66 ± 14.31),(69.66 ± ± 15.52),(85.70± 19.51) mg/L respectively.The concentrations of serum SAA and RBP in type 2 diabetic patients were significantly higher than those normal controls (t =10.36,P＜0.05;t =11.11,P＜0.05) and increased with DKD progression (F =83.6,P＜ 0.05;F =59.2,P＜ 0.05).Diagnostic sensitivity of serumSAA,RBP in DKD was 81.8％ and 84.1％ respectively.Diagnostic sensitivity of combined detection was 90.9％.Regression analysis showed that SAA,RBP and UACR were independent risk factors for DKD (OR (95％ CI) =1.391 (1.068-1.812),1.212 (1.085-1.353),1.148 (1.038-1.270);all P ＜0.05).Conclusion Both of serum SAA and RBP were significantly elevated in diabetic patients with renal injury so that they had great value in early diagnosis of DKD.
RESUMO
Objective To investigate the clinical value of serum lipoprotein (a) and free fatty acid (FFA) in the diagnosis of type 2 diabetic nephropathy (DN).Methods From January to October of 2016,120 cases with type 2 diabetes in the Second People's Hospital of Lianyungang were selected.According to urinary albumin creatinine ratio (UACR),the patients were divided into three groups:normal albuminuria group (NA),microalbuminuria group (MA) and macroalbuminuria group (LA).And 40 healthy subjects were selected as control group.The levels of serum lipoprotein (a) and FFA were measured,and the correlation was analyzed by Pearson analysis.Furthermore,the receiver operating curve was used to evaluate the positive diagnostic rate of DN.Results The levels of lipoprotein (a) in the NA,MA,LA and control group were (212.8 ±69.0)mg/L,(281.7 ±70.5)mg/L,(337.2 ±71.5)mg/L and (187.4 ± 74.0)mg/L,respectively.The levels of lipoprotein (a) in the MA and LA groups were significantly higher than those in the NA and control groups (F =35.08,P ＜ 0.05).The levels of FFA in the four groups were (0.63 ±0.15)mmol/L,(0.84 ±0.13) mmol/L,(1.07 ±0.19) mmol/L and (0.47 ±0.10) mmol/L,respectively.The level of FFA in the DN group was higher than that of the control group,the difference was statistically significant (F =102.13,P ＜ 0.05),and increased with the progression of DN.Pearson correlation analysis showed that the serum lipoprotein (a) was positively correlated with FFA (r =0.64,P ＜0.05).The positive rates of serum lipoprotein (a) and FFA were 64.2％ and 73.3％ in early diagnosis of DN,the positive rate of combined detection was 84.2％ (P ＜ 0.05).Conclusion Serum lipoprotein (a) and FFA levels are significantly increased in diabetic patients with renal injury.Both of them have important clinical value in early diagnosis of type 2 DN.

Objective To explore the clinical significance of changes of plasma Endothelim-1(ET-1)and serum Transforming Growth Factor-α(TGF-α),Transforming Growth Factorβ1(TGF-β1)levels in patients with liver cirrhosis. Methods The plasma ET-1 and serum TGF-α,TGF-β1 levels were determined in 66 patients with liver cirrhosis by RIA or ELISA,among which 30 cases had abdominal fluid while the other 36 cases had not In addition,35 healthy individuals were enrolled into the study as control. Results The plasma ET-1 levels were significantly lower in the patients group than control(P ＜0.01),while the serum TGF-α and TGF-β1 levels were significantly higher in the patients than those in control(P ＜ 0.01). In cases with abdominal fluid the plasma ET-1 levels were particularly high and had significantly negative correlation with serum TGF-α and TGF-β1 levels(r = -0. 4782,-0. 5014 respectively,P ＜ 0. 01). Conclusions The plasma ET-1,serum TGF-α and TGF-β1 levels were closely related to the diseases process of liver cirrhosis and had good clinical application values in diagnosis and prognosis.
