Objective To study the molecular mechanism of the remission in children with acute lymphocyte leukemia(ALL),as well as the expression of thyroid hormone receptor interacting protein 3(TRIP3) gene in children with ALL and explore the relationship between TRIP3 and ALL.Methods Fasting venous blood 2-4 mL was collected,anticoagulanted with ethylenediamine tetraacetic acid(EDTA),then perpheral blood mononuclear cells was collected by Ficoll density gradient centrifugation,total RNA was extracted by Trizol one step method.Reverse transcription-polymerase chain reaction(RT-PCR) was used to detect TRIP3 expression in peripheral blood lymphocytes in 73 ALL children of different stages and 20 normal children.The relationship between TRIR3 expression in children and ALL release was analyzed.Results 1.Expression of TRIP3 was significantly lower both after initial treatment and during recrudescence than that in normal children(Pa0.05).3.In children with ALL after initial treatment,the remission rate was significantly higher in TRIP3 positive patients than in TRIP3 negative ones(remission rate discern 25.0% vs 84.2%,P

Objective To compare the clinical outcomes of gefitinib and erlotinib treating non-small-cell lung cancer (NSCLC)with epidermal growth factor receptor (EGFR)mutation in either exon 19 or 21 . Methods A total of 242 patients diagnosed as NSCLC with EGFR mutation in either exon 19 or 21 from May 201 3 to December 2014 in our hospital were chosen in this study.According to age,sex,smoking history,eastern cooperative oncology group performance status and types of EGFR mutation,all the patients were matched to 121 pairs,and randomly divided into group A and B.Patients in group A received gefitinib treatment,and those in group B received erlotinib treatment.Based on the response evaluation criteria in solid tumors (RECIST),overall response rate (ORR),disease control rate (DCR),progression-free survival (PFS)were assessed.To assess the independent risk factors for PFS by univariate and multivariate Cox regression analysis.The subgroup analysis was performed for the 63 NSCLC patients using these two drugs as the first-line treatment.To evaluate the adverse drug reactions and quality of life between A and B groups.Results The median PFS of group A and B were 11 .6 months and 9.5 months,respectively,with no significant difference (HR =0.39,P >0.05).The ORR and DCR in the two groups were 76.9%,74.4% (χ2 =1 .03,P =0.58)and 90.1 %,86.8% (χ2 =1 .46,P =0.31 ). The independent risk factors of poor PFS were ECOG PS≥2 (HR =2.60,95%CI:1 .54 -4.43,P =0.001 )and non-adenocarcinoma (HR =3.61 ,95%CI:1 .54-8.66,P =0.003).For patients receiving these two drugs as the first-line treatment,there was no significant difference between two groups in overall response rates (76.6% vs. 90.2%,χ2 =0.83,P =0.12)and median PFS (11 .6 months vs.14.4 months,HR =0.59,P >0.05).The adverse drug reactions were significant differences in emotion function (F =10.27,P =0.03),diarrhea (F =10.24,P =0.03)and pain (F =9.02,P =0.04).After receiving drug treatment,the quality of life scores were improved,and most of the differences were statistically significant between A and B groups(P <0.05). Conclusion As for NSCLC with EGFR mutation in either exon 1 9 or 21 ,both gefitinib and erlotinib are well tolerated and have similar clinical effectiveness.

Objective To study the diagnostic value of multi-direction adjusted multiplanar reconstruction (MPR)by 64-slice CT myelography (CTM)in diagnosing cervical nerve injury,and the possibility of the MPR to replace conventional myelography and CT direct-scanning axial images.Methods Twenty-six patients with cervical nerve root injury were examined by conventional myelograpby and 64-slice CT using isotropic parameters.Then multi-direction MPR were performed to display nerve roots on coronal and sagittal planes besides axial images.Twenty-six patients were performed surgical operations and diagnosis were obtained.The coincident diagnosing rate with surgical operations results were compared statistically among multi-direction MPR,direct-scanning axial CT images,conventional myelography.The numbers of images were also compared between axial MPR and direct scanning axial CT images.Results Direct sign of nerve root avulsion was the loss of normal nerve root defect seen in the Isovist filled thecal sac in 6d-slice CT,which was found in 31 nerve roots.Indirect signs included:(1)Traumatic pseudomeningocele: 29 nerve roots showed the leak of Isovist into nerve root sheath,and extended into foramina;(2)Arachnoid cyst: 26 nerve roots clearly displays cystic distension in nerve root,which has low- density fine clew form septation from subarachnoid cavity and no nerve root in the cyst ;(3)Deformity of the subarachnoid space : deformity of thecal sac,partially lack of Isovist into arachnoid space,which was found in 17 nerve roots.The coincident diagnosing rate of cervical nerve root injury by multi-direction adjusted coronal MPR imaging was 92.6% (50/54),which was higher than by axial CT (77.8%,42/54)and conventional myelography (68.5%,37/54),There was significant difference between the conventional myelography, direct-scanning axial CT,multi-direction MPR images (Kappa = 0.686,0.772,0.920, respectively,P

Objective To investigate the effects of simvastatin on the expression of lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) induced by oxidized low-density lipoprotein (ox-LDL) or Glucose in U937 macrophages, and explore the role of NF-κB in modulating of LOX-1 expression. Methods U937 macrophages were treated with PMA to induce differentiation, which were co-cultured with 50 mg/L ox-LDL or/and 25 mmol/L glucose. Pyrrolidine dithiocarbamate (PDTC) and simvastatin (1 μmol/L or 10 μmol/L) were used to treat cells. The expression of LOX-1 protein and NF-κB ac- tivity were detected by enzyme-linked immunosorbent assay technology. The expression of LOX-1 mRNA was measured by RT-PCR. Results The expression of LOX-1 was up regulated by ox-LDL, glucose and combination of both. The inhibitor of NF-κB PDTC suppressed this up-regulation. Simvastatin suppressed the expression of LOX-1 induced by ox-LDL, and showed a significant effect in the higher concentration. There was no significant effect of simvastatin on the expression of LOX-1 induced by glucose. The variation of NF-κB activity was similar to that of LOX-1 expression. Conclusion Simvas- tatin suppressed the expression of LOX-1 induced by ox-LDL, while no significant effect on the expression of LOX-1 in- duced by glucose. The expression and regulation of LOX-1 were related with NF-κB pathway.
