Objective To study the correlation between histology and serological index changes in the patients with HBeAg-neg-ative chronic hepatitis B(CHB).Methods 135 cases of HBeAg-negative CHB underwent the liver biopsy,HBV-DNA copy and de-tection of serum alanine aminotransferase(ALT),total bilirubin(TBiL),aspartate aminotransferase(AST),albumin(ALB),pro-thrombin activity(PTA),hyaluronic acid(HA)and laminin(LN).The relationship between the histopathological findings and the se-rological examination results were analyzed.Results There were statistically significant differences between serum HBV-DNA copy levels and the liver tissue inflammation grades(χ2 =23.64,P <0.05);serum ALT,TBiL,AST,ALB,PTA and HA concentrations in the high grade of inflammation were higher than those in the low grade of inflammation,the difference was statistically significant (P <0.05);in which the concentrations of serum ALT,TBiL,AST and HA were positively correlated with the inflammation grades (P <0.05);while ALB and PTA and HA were negatively correlated with the inflammation grades(P <0.05).Conclusion The ser-um level of HBV-DNA copy,TbiL,ALT,AST,ALB and PTA concentrations are related with the inflammatory grade of liver tissue in the patients with HBeAg negative CHB,the serum HA level is related with the fibrosis level of liver tissue.These indicators could provide the reference value for judging the disease condition and prognosis of HBeAg negative CHB patients.

Objective To assess the volume of epicardial adipose tissue(EAT) and intrathoracic adipose tissue(IAT) and the correlation of EAT,IAT and the EAT/IAT ratio with the severity of coronary artery atherosclerosis in patients with metabolic syndrome(MS) and coronary heart disease(CHD).Methods Ninty-seven MS subjects without coronary atherosclerosis and one hundred and eighteen MS subjects with CHD were enrolled in this study.The volumes of EAT,PAT and IAT were measured using axial data from base to apex traced manually with a dedicated semiautomatic software program-volume.Results (1)Compared with MS subjects without coronary atherosclerosis,MS subjects with CHD had significantly increased age[(60.6± 1 1.4)years vs.(57.9 ± 8.7) years,P=0.001],positive family history of cardiovascular disease(29.7％ vs.21.6％,P=0.03),EAT[(98.3±41.4) cm3 vs.(82.2±39.7) cm3,P=0.001],IAT [(171.3±64.1) cm3 vs.(156.2±48.1) cm3,P=0.001] and HbA1c[(7.1 ± 1.8)％ vs.(6.6±2.3)％,P=0.02],but siginificantly reduced total cholesterol[TC,(4.9 ± 1.2)mmol/L vs.(5.4 ± 1.0) mmol/L,P=0.003],low-density lipoprotein cholesterol[LDL-C,(3.0±1.1) mmol/L vs.(3.6±1.0) mmol/L,P=0.03] and high-density lipoprotein cholesterol[HDL-C,(1.0 ± 0.4) mmol/L vs.(1.1 ± 0.3) mmol/L,P=0.04].(2) In MS subjects without coronary atherosclerosis,the volumes of EAT,pericardial adipose tissue(PAT) and IAT were associated with gender,body mass index(BMI),waist circumference(WC),diabetes mellitus and hyperlipidemia(all P＜0.05); however,in MS subjects with CHD,the volumes of EAT,PAT and IAT were associated with BMI and WC (both P＜0.05).(3) The volumes of EAT and IAT were correlated with calcification grades(r values were 0.45 and 0.50,P values were 0.017 and 0.013,respectively) and Gensini score(r values were 0.476 and 0.563,P values were 0.015 and 0.017,respectively) instead of coronary artery calcifacation score(CACS).Moreover,the EAT/IAT ratio was negatively correlated with CACS(r=-0.321,P=0.028).Conclusions Compared with MS subjects without coronary atherosclerosis,MS subjects with CHD have significantly increased EAT and IAT volumes.In our subjects,the volumes of EAT,PAT and IAT were associated with BMI and WC.Only in MS subjects with CHD,the volumes of EAT and IAT were correlated with caleification and Gensini score.

Objective To investigate the value of CysC-based CFR in comparison with creatinine-based GFR (CG-GFR and MDRD-GFR) as an accurate serum marker in the prediction of early diabetic nephropathy. Methods A tatal of 133 type 2 diabetic patients (74 males and 59 females, aged 58.1 ±12.3) were enrolled. The level of diabetic nephropathy (normoalbuminuric, microalbuminuric and macroalbuminuric) was staged and estimated GFR based on serum creatinine and cystatin C(CysC) was calculated. The plasma clearance of Tc-DTPA, serum CysC, creatinine, BMI, HbA1c, serum lipid and blood pressure were measured. Results 99mTc-DTPA-GFR was used as golden standard. At 90 and 75 ml· min-1· (1.73 m2)-1 cut-points, diagnostic efficiencies of CysC-GFR (89% and 92%) were better than those of CG-GFR (79%=86%, P=0.004, 0.04) and MDRD-GFR (80%-86%, P=0.02, 0.04). At 60 ml · min-1 · (1.73 m2)-1 cut-point, diagnostic efficiencies of CysC-GFR,CG-GFR and MDRD-GFR were 92%, 90% and 92% respectively (P= 0.49, P=0.71). The Logistic regression analyses showed that retinopathy, HbA1c, CysC, diabetic duration, and CysC-GFR were indicators to predict the development of microalbuminuria. Conclusion CysC-GFR is more valuable than CG-GFR and MDRD-GFR in the prediction of early diabetic nephropathy and should be applied clinically.
