Objective To investigate the relation between body mass index(BMI),skinfolds(SF)and relative weight(RW),arm girth(AG) and ag e of the children in order to look for the most suitable index used to diagnose children obesity in clinical work.Methods In 1496 healthy children (ranging from 1 to 13 years),their weight, height,AG, triceps skinfold(TSF), sub scapular skinfold(SSF) and abdominal skinfold(ASF) were measured and the relat ion of BMI,SF,RW,AG and age was analyzed.Results 1.Between BMI and the sum of three skinfolds(SF3) ,RW,AG,correlation coefficient was more t han 0.8(P＜0.001).2. With the increase of age, AG and ASF increase wh ile TSF and BMI decrease. 3.Skinfolds in girls of 3～6,12 years of age are thicker t han those in boys;BMI in boys of 8,9 years of age are higher than those in girls .Conc lusions 1.95 percentile of BMI and SF3 as index to diagnose children obes ity is better than single application of RW or one-site skinfold. 2.

To construct recombinant reporter plasmids containing different Alpha gene segments and Alpha1-TFEB fusion gene and to evaluate the promoter activity of the Alpha gene. Methods:Promoter regions of the Alpha gene were predicted using a software Primer 0.5. Five Alpha gene segments with different lengths and a normal TFEB gene promoter (pTFEB) were amplified via polymerase chain reaction, and recombinant reporter plasmids containing different Alpha gene segments and a normal TFEB gene pro-moter were constructed. Liposome transfection was used to transfect these vectors into the human embryo kidney 293T cells. The pro-moter activity of the Alpha gene was evaluated via luciferase assay. Meanwhile, the recombinant Alpha1-TFEB plasmid was construct-ed and transfected into the 293T cells. The TFEB expression of the recombinant Alpha1-TFEB plasmid was then detected via Western blot. Results: Recombinant reporter plasmids containing different Alpha gene segments and pTFEB were constructed successfully. Compared with the luciferase activity of pGL3-Basic, that of the groups with Alpha1, Alpha2, Alpha3, Alpha4 and Alpha5 significantly increased (P<0.01). The luciferase activity also increased significantly in the groups with Alpha1, Alpha2 and Alpha5 compared with that of the pTFEB group (P<0.01). The TFEB expression of the pGL3-Enhancer-Alpha1-TFEB was significantly higher compared with that of the pGL3-Enhancer group. Conclusion:In t(6;11) translocation RCC, the Alpha gene has a strong promoter activity and it en-hances TFEB expression. The strongest promoter activity region is in Alpha5 with a sequence from 643 bp to 693 bp.

Objective To evaluate if the assay of platelet-associated immunoglobulin G (PAIgG) can improve the sensitivity of monoclonal antibody immobilization of platelet antigens assay (MAIPA) in immune thrombocytopenic purpura (ITP).Methods Anti-GP Ⅱb/Ⅲa and anti-GP Ⅰb/Ⅸ autoantibodies were detected by a modified MAIPA;PAIgG was detected by competitive ELISA.MAIPA and PAIgG were done simultaneously in 190 patients with thrombocytopenia,in which 132 were diagnosed as ITP according to the diagnostic criteria Kappa test was used to analyze the concordance between MAIPA and PAIgG.Results The sensitivities of PAIgG alone or in parallel with MAIPA to ITP were 32.6% and 37.2% higher than MAIPA alone respectively,while their specifieities were 51.7% and 56.9% lower respectively.The sensitivity,specificity,positive predictive value,negative predictive value of PAIgG in series with MAIPA were all not superior to MAIPA alone.The kappa values between MAIPA and PAIgG in ITP and non-immune thrombocytopenia were 0.129 and 0.012 respectively,which meant the concordance between them was poor.Conclusion The detection of PAIgG should not be used as screening before MAIPA in distinguishing immune from non-immune thrombocytopenia.

Objective To examine the effect of epigallocatechin gallate (EGCG) at different concentration (0,10,25, 50 and 100μmol/L ) on proliferation rate and apoptosis of nasopharyngeal carcinoma cell line C666-1 in vitro, and elucidate the role of silent information regulator 1 (SIRT1). Methods The proliferation rate in vitro of C666-1 cells stimulated by EGCG at increasing concentrations (0,10,25,50,and 100 μmol/L)for 24 h or at concentration of 50μmol/L for 0,6,12 h and 24 h were detected by cell counting kit-8 (CCK-8) assays. Cell were treated with EGCG at concentration of 0,25, 50 and 100 μmol/L for 24 h, cell apoptosis was anylysed by TUNEL assay and expression levels of SIRT1 protein was detected by western blotting. Results EGCG suppressed cell proliferation of C666-1 cell line in a concentration-dependent manner at concentration of 0 ,10,25,50,and 100μmol/L, and in a time-dependently when treated with 50 μmol/L for 12 to 24 h(P<0.05). After treated for 24 h with different concentration of EGCG at 0、25、50、100 μmol/L, cell apoptosis increased at concentration of 50 to 100μmol/L and expression of SIRT1 decreased in a concentration-dependently (P<0.05). Conclusion EGCG induced cell apoptosis of C666-1 cells by down-regulating SIRT1 expression.

To study the changes of pupil diameter and its effects during phacoemulsification. METHODS: Block design, prospective study. 60 cataract patients (60 eyes) were selected, which divided into two groups according to the age, young age group (group A, 20 eyes of 20 patients) and older age group (group B, 40 eyes of 40 patients). Two groups were all given compound tropicamide eye drops for fully mydriasis before operation, computer software to process images during operation, and according to the cornea amplification ratio measure pupil diameter during the operation phase: before the corneal tunnel incision ( t1 ) , after injection of sodium hyalurantae ( t2 ) , before artificial lens implantation (t3), at the end of the surgery ( t4 ). Statistical analysis of data using SPSS18. 0 software.RESULTS: The pupil diameter measurements of t1-t4 were followed respectively:group A were 8. 36 ± 0. 65, 8. 97±0. 50, 8. 67±0. 63, 8. 72±0. 96mm; group B were 7. 73± 0. 58, 8. 23 ± 0. 59, 7. 89 ± 0. 16, 7. 70 ± 0. 63mm. Overall comparisons between the two groups, the pupil diameter measurements had differences during the operation phase ( F = 26. 696, P< 0. 05 ). Comparisons between the two groups at different time points: the pupil diameter of t1-t4 in group A was larger than that in group B, with statistically differences (P<0. 05). The pupil diameter of each groups had a tendency to change in different operation phrases, with no statistically differences (F=2. 617,P>0. 05). Comparisons in a group at different time points: the pupil diameter of t2 was larger than that in t1, with statistically differences ( P>0. 05), the pupil diameter of t3 and t4 were decreased in group B, with statistically differences (P<0. 05).CONCLUSlON: Compound tropicamide eye drops are given for mydriasis before operation, young patients with cataract and senile patients with cataract can achieve the effect of surgery for mydriasis, the pupil stability of phacoemulsification in senile patients with cataract are lower than that in young patients with cataract.
