Objective To study the relationship between renal morphology and renal function,and to assess the value of CT as a criterion to grade renal function.Methods Enhancement CT were performed in 89 patients with no local renal disease whose split renal glomerular filtration rates(GFR)were measured by renal dynamic imaging with ~(99)Tc~m-DTPA.The 178 kidneys were divided into normal renal function,mild and severe renal impairment groups according to renal function.Differences between three groups respect to the mean thickness of renal cortex and parenchyma were assessed by ANOVA.Using Pearson's correlation test,the correlation between the renal cortex,parenchyma thicknesses and renal GFR were examined.The value of CT in predicting renal function was assessed by using ROC analysis.Results The renal cortex thicknesses of normal renal function,mild and severe renal impairment groups were(5.9?1.1),(4.6? 1.1),and(3.3?1.0)mm respectively,and the renal parenchyma thicknesses were(26.3?4.2), (21.3?4.6),(16.2?4.6)mm.There were significant differences of renal cortex,parenchyma thicknesses between 3 groups(cortex F=54.78,P

Objective:To investigate the expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus- associated glomerulonephritis(HBV-GN).Methods:Twenty HBV-GN specimens with complete nephrology data and 10 normal renal specimens were randomly chosen for the present study.Cell apoptosis was detected by means of terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling(TUNEL)and the apoptotic index was calculated;immunohistochemistry was used to detect the protein expression of Bax and Bcl-2.ResuLts:The apoptotic index in HBV-GN group was obviously higher than that of the control group;the apoptotic cells were mainly distributed in the proximal and distal renal tubules and the collecting duct epithelial cells,seldom seen in the glomerular cells.The expression of Bcl-2 in HBV-GN patients was predominately present in the renal tubular epithelia cells(positive in the plasma,membrane and nuclear);the expression of Bax was found in both glomerular cells and renal tubular cells,mainly in tubular epithelial cells,seldom seen in Bowman's capsule or glomerular mesangial region.Conclusion:Apoptosis in the kidney of HBV-GN patients mainly occurs in the renal tubular epithelial cells;expression of Bax and Bcl-2 is mainly in the renal tubular epithelial cells,suggesting that the injury of tubular interstitial damage may be one of the important factors for the development of HBV-GN.

OBJECTIVETo discuss that pathogenesis evolvement regularity of Chinese miniature swine with phlege-stasis cementation syndrome of coronary heart disease.

METHODEighteen Chinese miniature swine were randomly divided to the normal control group, the model group and the Danlou tablet group, with six swine in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. The levels of BMI, hemorheological parameters, lipids in serum and inflammatory cytokines were observed at the 0th (before the experiment), 2nd (before operation or drug administration), 6th (four weeks after drug administration) and 10th week (eight weeks after drug administration) of study. The levels of TG and TC in liver and the pathological changes in coronary artery tissues were also observed at the end of study.

RESULTCompared with the normal control group, the model group had showed significant increase in the levels of TC, TG, LDL-C and VLDL-C in serum (P < 0.01) from the second week to the end of the experiment, with notable rise in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1). At the 6th week, the levels of BMI and TG and TNF-alpha in serum significantly increased. At the 10th week, the levels of BMI and hs-CRP, IL-6 and TNF-alpha in serum significantly increased as well, with remarkable increase in coronary stenosis, intimal thickness and the ratio between intimal thickness and media thickness (P < 0.05 and P < 0.01), and significant rise in TC and TG in livers (P < 0.01). Compared with the model group, the Danlou tablet group showed obvious reduction in severity of coronary artery lesion, intimal thickness and lumen stenosis ratio and ratio between intimal thickness and media thickness (P < 0.01), BMI, TC, TG, LDL-C and VLDL-C in serum, TC and TG in liver, as well as hs-CRP, IL-6 and TNF-alpha levels in serum (P < 0.05 and P < 0.01), with notable decline in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1).

CONCLUSIONThe interaction of phlegm, blood stasis and toxin syndromes helps promote the progress and development of AS plaques, which is the key pathogenesis of phlegm-stasis cementation syndrome in coronary heart disease.

Sailuotong (SLT) is a compound preparation composed of ginseng, ginkgo and saffron for the treatment of vascular dementia In order to identify its material foundation and provide evidence for therapeutic regimen, the pharmacokinetics and brain distribution of ginsenosides were investigated after intragastric administration of SLT. An LC-MS/MS method was developed for the determination of 7 ginsenosides in rat plasma simultaneously. Statistical analysis of obtained data demonstrated that the method has achieved the desired linearity, precision, accuracy and sensitivity. After administration of SLT at 60 mg x kg(-1) dose, 7 ginsengosides were all absorbed into systematic circulation. The quantitative and statistical analysis of gensenosides in plasma showed that protopanaxdiol saponins exhibited higher concentration and longer half life than protopanaxatriol saponins. The mean value of half life of ginsenosides Rg1, Re, Rb1, Rb2/b3, Rc and Rd were 15.26, 2.46, 18.41, 27.70, 21.86 and 61.58 h respectively. The peak concentration of them were 7.15, 2.83, 55.32, 30.22, 21.42, 8.81 microg x L(-1) respectively. The determination of brain distribution at different time after dosing revealed ginsenosides entered into brain promptly but the concentration declined along with time rapidly. The ginsenosides with higher concentration in brain were Rg1, Re, Rb1 and Rc. These findings demonstrated ginsenosides could be absorbed in blood and penetrated into brain rapidly. Some ginsenosides, especially Rg1 and Re, might be the main components directly effecting neurocyte in brain taking advantage of their better brain distribution. While ginsenosides of mostly protopanaxdiol saponins might protect brain mainly depending on peripheral efficacy in virtue of their long residence in blood, by which higher concentration could be reached after multiple dosing.

Objective To detect the levels of transforming growth factor-?_1(TGF-?_1) in plasma,serum and urinary of children with Immunoglobulin A glomerulonephritis(IgAGN) and mesangial proliferate glomerulonephritis(MsPGN) and explore the different effects of TGF-?_1 in the two diseases.Methods The plasma,serum and urinary TGF-?_1 levels were measured in 24 children with IgAGN,and 30 children with MsPGN and 30 healthy controls by enzyme-linked immunosorbent assay(ELISA).Results The TGF-?_1 levels in plasma,serum and urinary samples of IgAGN group were increased.The TGF-?_1 levels of IgAGN were significantly higher than those of MsPGN and heathy controls(P(0.05)).Conclusion It is showed that TGF-?_1 plays a diffenent role in IgAGN and MsPGN.

Objective To investigate the factors influencing the wall elasticity of carotid artery and the effect of hyperlipidemia on carotid artery elasticity in children.Methods Fifty-seven healthy children and 23 children with hyperlipidemia matched for age and sex were involved in the study.The pressure-strain elastic modulus(E?),stiffness parameter(?) and arterial compliance(AC) of carotid artery were measured by Aloka echo-tracking system.Correlations between age,blood pressure and E?,?,AC were analyzed in healthy children,respectively.Results In healthy children,age,systolic blood pressure and pulse pressure were positively correlated with E? and ?,and negatively correlated with AC.E? and ? significantly increased in children with hyperlipidemia compared to those in healthy children,and AC obviously decreased.Conclusions Hyperlipidemia might decrease the wall elasticity of carotid artery in children.Age and blood pressure are also factors affecting carotid artery elasticity in children.J Appl Clin Pediatr,2006,21(3):142-143
