Objective To investigate the structure of Tn1546 like elements,the molecular features and genetic background of VanB phenotype-vanA genotype VREs and to explain the difference between phenotype and genotype. Methods Twenty-one VREs were collected in Beijing Hospital from March 2008 to January 2009. Etest was used to determin MICs of ten antibiotics. PCR product sequencing, PFGE and MLST were performed to study the molecular features and genetic background of the 21 VREs. Results All VREs were vanA genotype, but 3 of them( 14. 3% ) exhibited the VanB phenotype. Based on PFGE analysis, 21 VREs belonged to 9 different patterns. Six STs were identified by MLST analysis. The analysis of the structure of Tn1546 like elements showed the deletion of vanY, vanZ and the insertion of ISEfa4 in orf2-vanR intergenic region may be related to the formation of VanB phenotype-wanA genotype. Conclutions VanB phenotype-vanA genotype VREs were rarely found in China. The results of vanA cluster rearrangements could partly explain the causes of difference between phenotype and genotype.

Aim To investigate the impact of CYP3 A5 genetic polymorphism on modified releasing tacrolimus pharmacokinetics in Chinese stable renal transplant re-cipients. Methods Pharmacokinetics of once daily-ta-crolimus( tac-q. d. ) and twice daily-tacrolimus( tac-b. i. d. ) were determined by CLIA, CYP3A5 genotype was measured by PCR-RFLP. Each 10 patients receiv-ing tac-q. d. and tac-b. i. d. respectively were en-rolled, and each 5 patients receiving tac-q. d. were matched to poor metabolizer ( PM ) and extensive me-tabolizer ( EM ) group respectively according to CYP3A5 genotypes. Results AUC0~24 h for tac-q. d. was 1. 78 folds higher than AUC0~12 h for tac-b. i. d. , and dose-adjusted C0 was 40% lower for tac-q. d. than for tac-b. i. d. There were no significant differences for other parameters between the two groups; Cmax, AUC0~24 h and C0 were 1. 75, 1. 96 and 2. 49 folds higher for PM than for EM, and dose-adjusted Cmax, AUC0~24 h and C0 were 1. 80, 2. 34 and 2. 64 folds higher for PM than for EM. There were good correla-tions between AUC0~24 h and C0 for tac-q. d. Conclu-sion Conversion from tac-b. i. d. to tac-q. d. results in requirement of increased tacrolimus dose and detec-tion of CYP3A5 genotype, which is necessary for ensu-ring C0 in the range of therapeutic window.

Impaired tumor necrosis factor receptor-1 (TNFR-1) signaling has been found in some malignant tumors with poor prognosis. However, the exact role of TNFR-1 signaling in fibrosarcoma remains unclear. Here, we explored the question by comparing the growth of TNFR-1 deficient (Tnfr1 (-)) and TNFR-1 competent (Tnfr1 (+)) fibrosarcoma FB61 cells (FB61-m and FB61-R1) in mice. TNFR-1 expression on fibrosarcoma cells delayed their growth in vivo but not in vitro. Moreover, reduced FB61-R1 tumor growth was also obtained in TNFR-1 knockout mice. The mechanism relies mainly on the TNFR-1-mediated downregulation of vascular endothelial growth factor (VEGF) production by tumor cells. Importantly, treatment of FB61-m tumors with melphalan resulted in a short delay of tumor growth, followed by a quick remission. However, when FB61-R1 tumors were treated with melphalan, tumor growth was similarly delayed at first and then completely rejected. Our results reveal evidence for TNFR-1 on tumor cells as a prerequisite in chemotherapy for fibrosarcoma, and provide novel insight into the therapeutic approach against some types of tumors using TNFR-1 angonist.

Objective :
To investigate the neurobehavioral development of young children aged 24 to 60 months in Shunde and explore the factors influencing the development of young children and provide reference for the interven- tion of neurobehavioral development delays in young children.
Methods :
A retrospective cohort study was used to enroll the young children who were initially screened by the Pediatric Neuropsychological Developmental Scale (Pe- diatric Heart Scale) with a score of ≤85 was included in the study.With a score of ≤85,the young children might be at risk of developmental delays,and needed to be further diagnosed by the GESELL Developmental Diagnostic Scale,the basic information of the young children and their mothers at the time of birth were investigated,as well as basic information about the young children at the time of completing the GESELL Developmental Diagnostic Scale was collected.
Results :
A total of 271 young children were included,196 males and 75 females.Young children had the lowest developmental quotient (DQ) in the language domain among the five domains (P<0. 001) .Multiple lin- ear regression models showed : compared with girls,the language domain DQ of boys decreased by 5. 321 points (P = 0. 049,95% CI : -10. 620 --0. 021) ,and the personal-social domain DQ decreased by 4. 474 points (P = 0. 023,95% CI : -8. 316 --0. 631) .Compared with young children via natural vaginal delivery (NVD) ,the gross motor domain DQ of young children via caesarean section ( CS) decreased by 4. 890 points (P = 0. 008,95% CI : - 8. 499 --1. 281 ) ,the fine motor domain DQ decreased by 3. 373 points ( P = 0. 037,95% CI : -6. 532 - - 0. 213) ,the language domain DQ decreased by 7. 621 points (P = 0. 004,95% CI : -12. 826 --2. 416) ,per- sonal-social domain DQ decreased by 6. 232 points (P = 0. 001,95% CI : -10. 006 --2. 457) .The results of bi- nary logistic regression models showed,compared with young children via NVD,the risk of gross motor domain retar- dation in young children increased ( OR = 1. 763,95% CI : 1. 003-3. 100) ,the risk of fine motor domain retardation increased ( OR = 2. 217,95% CI : 1. 235-3. 980) ,the risk of language domain retardation increased ( OR = 3. 306, 95% CI : 1. 080 -10. 124) .
Conclusion
Young children with suspected neurobehavioral delays were more likely to have delayed development in language domain than in other domains,boys had lower DQ in language domain and personal-social domain than girls,and the development of young children via CS was slower than that via NVD.Fo- cus should be on the language development of young children especially on the language and personal-social devel- opment of boys.Carefully chose delivery way.Focus should be placed on assessment of young children's comprehen- sive neurobehavioral development in early time.
