Objective To explore the clinical value of high-sensitivity C-reactive protein(hsCRP) in chronic kidney disease(CKD) and the relationship between hsCRP and the different stages of CKD in children.Methods This study population consisted of patients who was diagnosised as CKD in Beijing Children′s Hospital from Mar.2007 to Feb.2008.The total number of subjects was 62 patients with 35 male and 27 female,the mean age was(8.7?4.0)years old,the course was from 3 months to 10 years.The healthy control group contains 30 healthy children with 16 male and 14 female,the mean age was(7.8?3.2) years old.The serum levels of hsCRP,creatine and ?2-microglobulin(?2-MG) were determined.The glomerular filtration rate(GFR) was caculated.The relationship between serum levels of hsCRP and ?2-MG,blood pressure as well as the renal function in these patients with CKD,stratified according to GFR were evaluated.The relationship between hsCRP and the blood pressure was evaluated.The statistical analysis for the data was done with SPSS 12.0 software.Use the t-test,order and examination and correlation analysis,P

Objective: To investigate the effects of common peneration enhancers on the transdermal permeation of total flavones and six flavonoid components from Scutellariae Radix Gel-unguentum (SRGU), thus to provide the experimental evidence for the selection of optimal penetration enhancers. Methods: In vitro diffusion cell method was used to evaluate the changes of the transdermal pemeation parameters by azone (AZ), menthol (MT), and propylene glycol (PG), separately or in combination. Results: When applied individually, AZ and MT showed the best enhancing effect on the transdermal permeability and cumulative permeation of flavonoids and their aglycons, respectively. PG, in contrast, produced poor enhancement. When applied in combination, the permeation enhancing effects were generally more remarkable than those of single enhancer. In particular, 3% AZ + 5% PG could achieve the most effective enhancement effect on the transdermal permeation of flavonoids. Conclusion: Penetration enhancers could significantly affect the transdermal permeation of total flavones and flavonoid components from SRGU in vitro, and 3% AZ + 5% PG may serve as the most effective enhancer.

A comparative study on the glycolic acid oxidase (GO) of the domestic Spirulina(Arthrospira) platensis (S_(1)) from alkaline lake in Erdos Plateau and the imported S. (A.) platensis (S_(2)) and S. (A.) maxima (S_(3)) as well is made with colorimetric method. The results show that activity of GO (25℃, pH 8.0) of S_(1), S_(2 )and S_(3) is 70.9 U/gFW, 59.6 U/gFW and 80.9 U/gFW respectively; the GO's optimum temperature of S_(1)、S_(2) and S_(3 )is 30℃; the GO's optimum pH value of S_(1 )is 8.6,while that of S_(2 ) 8.2 and that of S_(3) 8.4; the GO of S_(1 )is stable from 0℃ to 35℃ and from pH 7.6 to pH 10.0, while that of S_(2) from 0℃ to 30℃ and from pH 8.0 to pH 9.0 and that of S_(3) from 0℃ to 35℃ and from pH 8.0 to pH 8.6. Adaptive range of S_(1) GO for temperature and pH is wider, and activity at low and high temperature and under strong acidand alkali conditions is higher than that of the imported species.

Objective To investigate the influence of Helicobacter pylori(Hp) infection on gastric mucin MUC5AC and MUC6 expression in children.Methods Sixty-six cases with gastric biopsy specimens were obtained from 66 children undergone gastroscopy from Jan.2005 to Jun.2006 for episodic or continuous abdominal pain,nausea,vomiting,abdominal distension,retching and dyspepsia,and so on.Among these children,39 cases were male and 27 cases were female,owning a average age(8.8?3.0)years.These specimens were divided into 2 groups followed by the presence of Hp,which was detected by rapid urease tests and Hp-PCR.Gastric mucin MUC5AC and MUC6 mRNA were also measured by reverse transcription PCR(RT-PCR),and Hematoxylin and Eosin staining were used for pathology observation.Comparisons between every groups were performed using t test and ?2 test,and statistical significance was defined as P

Objective To observe the expression of leukocyte-function-associated antigen-1(LFA-1)immunoreaction in children with febrile seizures(FS),and explore the neuroimmunomodulation mechanisms in the pathogenesis of FS.Methods Adopting flow cytometry(FCM),the levels of LFA-1 contained in blood serum and peripheral blood mononuclear cells(PBMC)of 60 cases [simple FS(SFS)30 cases;complex FS(CFS)30 cases] with febrile convulsion were analyzed,and compared with those in a normal group(30 cases).Out of 60 children with FS group,the LFA-1 mRNA in 20 cases with SFS and 20 cases with CFS was analyzed,and LFA-1 mRNA in19 health children taken out from control group(30 cases)was analyzed.The real-time PCR was used to detect the expression of PBMC LFA-1 mRNA.Results The expression of LFA-1 in the surface of PBMC of the 3 groups,the highest LFA-1 level was in the SFS group(50.89?21.36),the lowest LFA-1 level was in the CFS group(34.35?11.45),and control group was(41.39?16.30).Significant differences were found in 3 groups(Pa
