OBJECTIVE:To probe into the situation of drug use that goes beyond the scope of package inserts in pediatrics of our hospital and to promote clinical rational drug use.METHODS:A total of 3 142 prescriptions between Mar.and Apr.2006 collected from the pediatric out-patient department of our hospital were analyzed in accordance with the contents of the related drug package inserts.RESULTS:Of the total 3 142 prescriptions,345(11.0%) involved drug use that goes beyond the scope of package inserts,leading the list were prescriptions of infants,accounting for 71.3% of the total.The problems such as age(52.2%) and indication(36.5%) were the main type;respiration system drugs(48.4%) and the antibiotics(40.6%) were the main drug kinds involved.CONCLUSIONS:It's widespread for drug use that goes beyond the package inserts in the pe-diatrics,which conforms to evidence-based medicine and the spirit of philosophy and ethics,but against the principle of law,which thus should be given fully attention in the clinic.

HDL or apolipoprotein A-Ⅰ,the major protein of HDL particles,protect host against vascular endothelial dysfunction.HDL binding to scavenger receptor-BI activates eNOS for increasing NO.SR-BI and Endothelial lipase(EL) play a critical role in the regulation of plasma HDL.Incubation of HDL with vascular endothelial cells promotes prostacyclin synthesis.Some proteins such as paraoxonase that cotransport with HDL in plasma,have antioxidant properties.HDL inhibits TNF-? dependent expression of adhesion molecules in vascular endothelial cells and interferes with apoptosis,proliferation and migration of vascular endothelial cells.

Objective To evaluate the clinical value of combined detection serum anti-HCG and estradiol and progesterone in infertile women.Methods Serum estradiol(E2) and progesterone(P) in infertile women were detected by ECLIA , Anti-HCG were detected by ELISA.Results the levels of estradiol(E2) and progesterone(P) in anti-HCG positive group were significantly lower than those in anti-HCG negative group.Conclusions The combined detection of anti-HCG and estradiol and progesterone were of important clinical value in diagnosis of infertile women.

0.05).After stimulation,IP of two groups all increased accord with stimulating frequencies,and that in RSV group was much higher than that in controls.After giving pilocarpine,IP of controls decreased according to the doses of pilocarpine,while the extent of decrease in RSV group was much less than that in controls,which had significant difference(P

Objective To do analysis of sequence and identify a novel HLA-A allele in Chinese hematopoietic stem cell do-nors.Methods A rare HLA-A allele was initially detected by Luminex PCR-SSO typing,then the sample was sequenced by sequence-based typing (SBT)and the group-specific sequencing primer (GSSP)to confirm the mutation allele and locus.Re-sults The sequence of the sample results showed that the allele compared with the highest homologous allele HLA-A*24∶02∶01∶01 was the difference in the exon 3 at position 544 G>A,resulting in an amino acid sequence of HLA-A*24∶02∶01∶01 at position 158 change Ala to Thr.Conclusion This allele is a new HLA-A allele and has been designated as HLA-A*24∶327 by the HLA Nomenclature Committee of World Health Organization (WHO).

Objective To investigate the effects on one hand of training the other with isometric wrist extension and flexion training and its underlying mechanism.Methods Twenty healthy young girls were recruited and randomized into a training group and a control group with 10 subjects in each,using a random number table.The subjects in the training group were accepted isometric training of the wrist extensors and flexors on the right side once every other day,4 days a week for 6 weeks according to a pre-programmed protocol,while those in the control group had no intervention.Peak torque and surface electromyography (sEMG) were recorded and assessed before and after 6 weeks of training.Results In the training group,the average peak torque of right wrist flexion and extension were both significantly higher than before training (within-group comparison) and higher than in the control group (between-group comparison) after 6 weeks of training.The average peak torques of the left wrist in the training group in flexion and extension were (12.9±2.0) Nm and (6.4 ± 1.3) Nm after training,both significantly higher than before the training and stronger than the control group.In the sEMG traces during wrist extension,after training the ascend velocity of the right extensor carpi ulnaris and the integrated area of the left extensor carpi ulnaris in the training group were significantly smaller than before training and in the control group.Conclusion Unilateral isometric resistance training of the wrist muscles can transfer to the contralateral side,probably by altering muscle recruitment.

Objective To investigate the extent of cross-education between the pronation and supination muscles of the right and left forearms after unilateral isometric training.Methods Twenty healthy young girls were randomized into a training group and a control group using a random number table.The training group underwent isometric training of their right forearms for six weeks,while the control group continued ordinary life without exercises.Pronation peak torque (PPT) and supination peak torque (SPT) were assessed before and after the training for both groups.Results The differences in PPT or SPT between the training group and the control group were not significant before the training program.When the training had been completed,however,the average PPT and SPT on right side of those trained of course had increased significantly compared to before training or to the control group.More significantly,the average PPT and SPT on the left side in the training group were also significantly better than before training or in the control group after training.Conclusion Unilateral isometric training of the forearm pronation and supination muscles for six weeks can significantly increase muscle strength bilaterally,indicating good cross-education.

Objective To identify the mechanisms underlying xCT deficiency by high-resolution proteomic analysis of differential protein expression in Sut and wild melanocytes .Methods The proteins,extracted from Sut and wild melano-cytes,were analyzed by two dimensional electrophoresis and PDQuest software .Subsequent MALDI-TOF mass spectrometry analysis was carried out .The protein identification was based on peptide mass fingerprint combined with the pI and the rela -tive molecular mass ( Mr) .Sequence coverage was performed with the Peptldent software on the NCBnlm website .Also,the autophagy marker protein LC3-Ⅱ, and the autophagic cell death marker protein Beclin 1 were detected by Western blotting . Results and Conclusion Twenty apparently upregulated or downregulated proteins were identified .Strikingly, important modifications in regulators of trafficking and organization of vesicles and autophagy ( Anxa3; Hist 1h2bk, NDRG1, and CaM) and in regulators of invasion and metastasis of carcinoma (S100A-4;S100A-6 and vimentin)are likely to account for dysfunctions in cell viability and cell-extracellular adhesion .These results indicate that the proteins regulating autophagy , vesicles trafficking and MAP kinase related pathways are activated and play a role in xCT-deficiency .

Objective To investigate whether the gamma-aminobutyric acid (GABAB) receptor genes,including gabbr1 gene and gabbr2 gene,are the susceptible genes for simple febrile seizures (sFS) by screening mutation of gabbr1 gene and gabbr2 gene and to study the possible association between sFS and the 2 genes.Methods All exons and flanking introns of gabbr1 gene and gabbr2 gene were amplified with polymerase chain reaction (PCR) and sequenced to screen the possible mutation on 60 children with sFS in the northern China in Han nationality population.One hundred and one healthy children from the same area were selected as controls,and the genotypes of single nucleotiole polymorphisms (SNPS) (rs29220,rs29230,rs29267 on gabbr1 gene and rs1000440,rs3205936,rs2304391 on gabbr2 gene) were typed by PCR-restriction fragment length polymorphism.EH1.20 software was used to estimate haplotype frequency to study the association with the haplotype as genetic marker between case group and control group.Results No mutation associated with sFS was found in the 60 sFS cases.In all sequenced regions,23 SNPs were identified in both genes:6 SNPs in gabbr1 gene and 17 SNPs in gabbr2 gene.The frequencies of the 6 SNPs were complied well with the Hardy-weinberg equilibrium in sFS group and normal group.Genotype proportions and allele frequencies of 6 SNPs were not significantly different between both groups.The haplotypes of 3 SNPs in gabbr1 gene and in gabbr2 gene distributions were not significantly different between 2 groups.Conclusions No mutations and associations were identified between sFS with both GABAB receptor genes(gabbr1 gene and gabbr2 gene).They may not be the susceptibility gene for simple febrile seizures in Han nationality population in northern China.

Objective To revise the trait self-control scale for Chinese college students.Methods According to the theory,12 items were selected,then data were collected from a sample of 549 and 133 college students of Harbin.Explorer Factor Analysis,Confirmatory Factor Analysis,reliability test and validity test were used.Results ①Trait self-control scale for college students included eight items,two dimensions were restrained and impulsivity,two dimensions can explain 42.90％ of the total variance.②Confirmatory Factor Analysis showed that the two-dimensional structure was reasonable (x2/df =1.24,CFI =0.97,GFI =0.96,AGFI =0.92,IFI =0.97,TLI =0.96,RMSEA =0.04).③The restrained factor scores were positively correlated with satisfaction of life scores and adaption scores(r=0.23,0.48,P＜0.01),while negatively correlated with negative affect (r=-0.19,P ＜0.01).The impulsivity factor scores were negatively correlated with satisfaction of life scores and adaption scores (r=-0.18,-0.34,P＜0.01),while positively correlated with negative affect(r=0.22,P＜0.01).④The composite reliability coefficients of the scales were good:the coefficient of the subscale restraint was 0.69,and the coefficient of subscale of impulsivity was 0.64,the coefficient of the whole scale was 0.80.The two months test-retest reliability coefficient of 133 subjects was 0.66.Conclusion The revised scale of trait self-control scale has good psychometric quality and can be used in Chinese college students.
