T were also detected in the controls.Conclusion Nephrotic syndrome may be associated with NPHS2 identified in children.

Objective To explore the influence of lamotrigine(LTG)and valproate(VAP)on cognitive function in children with epilepsy.Methods Seventy-six epileptic children firstly diagnosed were chosen,36 cases received LTG monotherapy and 40 cases undwent the treatment of VPA.The intelligence quotient(IQ)value was measured before and after 6 months treatment respectively,and 20 healthy children were selected as healthy control.Results 1.The epileptic children had poor verbal intelligence quotient(VIQ),performance intelligence quotient(PIQ)and full intelligence quotient(FIQ)compared to the control subjects(Pa0.05).But among the subtestings,the know-ledge,wood-graph,coded score of the VPA groups had significant difference(Pa

OBJECTIVETo observe features of Icariin in promoting osteogenic differentiation of SD rat bone marrow mesenchymal stem cells (BMSCs) in vitro.

METHODS(1) SD rats' BMSCs were isolated and purified by mechanically isolated and cultured by whole bone marrow adherent method. Effects of various concentrations Icariin on serum activities of alkaline phosphatase (ALP) were detected using amino antipyrine phenol determination method at day 3, 6, 9, 12, 15, 18, and 21. Calcium nodes of each groups were detected using alizarin red staining. Roles of various concentrations Icariin in promoting osteogenic differentiation of BMSCs were observed. (2) BMSCs were divided into the blank control group, the osteogenic induced group, and the Icariin group (0.5 microg/mL). ALP activities were detected at day 7, 14, and 21 of culture. Meanwhile, ALP positive staining rate and calcium nodes were detected at day 14 and 21 respectively. Additionally, mRNA expressions of Runt-related transcription factor-2 (Runx2) and Osteocalcin were detected at day 7, 14, and 21 by real-time fluorescent quantitative PCR.

RESULTS(1) 0.05-5.0 microg/mL Icariin could significantly elevate serum ALP activities. Of them, 0.2-2.0 microg/mL Icariin significantly increased calcium nodes numbers (P < 0.01). (2) When Icariin promoted osteogenic differentiation of BMSCs, Runx2 mRNA expression levels and ALP activities increased earlier and then decreased, while osteocalcin mRNA expression levels continued to increase (P < 0.01). Compared with the osteogenic induced group, ALP activities and ALP positive staining rate were both elevated after 14 days of Icariin treatment in the Icariin group (P < 0.05, P < 0.01).

CONCLUSIONSIcariin could promote the differentiation of BMSCs to osteoblasts by up-regulating Runx2 mRNA expression levels. It also could promote the mineralization by increasing ALP secretion and Osteocalcin mRNA expression levels, thereby promoting mature of newly generated osteoblasts.

Objective To establish a real time reverse transcription polymerase chain reaction method for detecting WT1 and to understand the expression levels of WT1 in acute lymphocytic leukemia(ALL) of children through examining peripheral blood of leukemia children.Methods Thirty ALL patients, 13 non-leukemia Children and 18 normal children were included in this study. The method of real time RT-PCR detecting the expression of WT1 was established. The expression levels of WT1 gene were tested by this method.Results The expression levels of WT1 in 13 ALL with newly diagnosed patients were (105-106)copies/?g RNA, 12 with partial remission were (102-104)copies/?g RNA and 12 with complete remission were (0-102)copies/?g RNA.Conclusions Significant expression levels of WT1 in ALL are higher than those in non-leukemias and normal children.WT1 could be a marker for detecting minimal residual disease and evaluating therapy efficacy in ALL.

The rice gall dwarf disease, caused by the Rice gall dwarf virus (RGDV) is a serious disease occurring in rice in many regions of Guangdong province. As a basis to control the disease we have studied the genomic diversity of a variety of isolates from different locations. Genome segment 8(S8), encoding a main outer capsid protein (Pns8) of RGDV five isolates (BL, CH, DQ, GZ, XY) from Guangdong province was cloned and sequenced. The results revealed that all the S8 segments of the five isolates consisted of 1 578 nucleotides and had a single open reading frame (ORF) extending for 1 301 nucleotides from nucleotide 21 which encoded a polypeptide of 426 amino acids with an estimated molecular weight of 47.4 kDa. The S8 full-length sequence and the ORF sequence shared 97.3%-98.8% and 97.3%-99.1% nucleotide sequence identities within the five Chinese isolates, and shared 94.8%-95.6% and 95.0%-96.0% identities with those of the Thailand isolate respectively. The deduced amino acid sequence of Pns8 in GZ isolate was identical to that in the Thailand isolate, while the amino acid sequence variability of Pns8 within five Chinese isolates ranged from 0.5% to 2.1%. These results indicate that the S8 segment of RGDV is highly conserved in different isolates from different locations. The S8 cDNA from the XY isolate was cloned into the plasmid vector pET-28b(+) and a fused expression protein with an apparent molecular mass of 51kDa was specifically detected in an analysis of Escherichia coli Rossetta(DE3)Ⅱcells. To our knowledge, this is the first report on analysis of the RGDV segment 8 sequence and genetic comparison of different RGDV isolates and their protein expression.

Aim To study relative bioavailablity of cefaclor effervescent tablets in healthy volunteers. Methods According to the crossover design, A volunteers were each orally given a single does of the 0.75 g cefaclor effervescent tablets and cefaclor capsules with an interval of 5 days between the two formulations.The plasma concentrations of the drug were determined by RP-HPLC.Pharmacokinetic parameters were obtained by ATPK programe,and calculated on the basis of open single compartment model.Results After a single oral dose, the peak levels in plasma averaged Cmax(31.27?5.81)?g?ml-1 and(30.56?5.25) ?g?ml-1 at (0.58?0.12)h and(0.73?0.17)h and AUC0～4(35.48?4.65) ?g?h?ml-1 and (35.89?2.90) ?g?h?ml-1 for tablet and capsule,respectively. Conclusion The result shows that two formulations are bioequivalence.
