Objective:To determine the relationship between brachia l artery blood pressure and radial artery blood pressure in children and whether blood pressure measured from the radial artery can replace blood pr essure measured from the brachial artery. Methods:Brachial and rad ial artery pressures in 105 children were measured using an electronic sphygmomanometer.Results:There was no significant difference between the average values of blood pressures of the brachial and radial arteries in the 105 children studied (P>0.05). Linear regression and correlation analyses showed that there was a positive linear correlation between the systolic pressure of the b rach ial artery and the radial artery in the 105 children, as well as a posit ive linear correlation between the diastolic pressures of the brachial and the radial arteries. Conclusion:Blood pressure values from the radial artery can completely replace blood pressure values from the brachial artery.

ObjecfiveTo compare the sensitivity of diffusion weighted imaging(DWI)with dynamic contrast enhanced(DeE)MRI for the detection of small breast caJlcers and to evaluate the clinical value of DWI.MethodsForty-eight patients with benign(n=25)and malignant(n=45)small breast lesions(≤2 cm)proved by pathology underwent DWI and DCE MRI.The DCE MRI was performed using FLASH sequence and the time-signal intensity chive was drawn.The DWl was performed using GRAPPAEPI sequence with different b values(800,1000 s/mm2) and the ADC values of lesions were measured.The sensitivity and specificity of DWI for the detection of small breast cancers were compared with DCE MRI. ResultsForty of 45 small breast cancers and 19 of 25 small benign breast lesions were corrlectly diagnosed using DCE MRI.The sensitivity and positive predictive value of TIC were 88.9%(40/45)and 87.0%(40/46).With b values of 800 s/mm2 and 1000 s/mm2,the avemge ADC values of small breast cancers were(1.153±0.192)× 10-3 and(1.079±0.186)× 10-3 mm2/s,while those of benign ones were (1.473±0.252)×10-3 and(1.419±0.255)×10-3 mm2/s,respeetively. There was no significant difference for the ADC values with different b values in the same group(P＞0.05),while there was a signiticant difference between the malignant and the benign lesions(P＜0.05)Thirty-nine of 45 small breast cancers and 19 of 25 small benign breast lesions were correctly diagnosed using DWI with b value of 1000see/mm2.Both the sensitivity and positive predictive value of diagnosis were 86.7%(39/45).The abilities of DWI and DCE MRI for the diagnosis of small breast cancers werle the same. The sensitivity(93.3%)and positive predictive value(91.3%)were improved with the combination of DCE MRI and DWI. Conclusion DWI has a high sensitivity for the detection of small breast cancers,the ADC value can provide valuable information in the differential diagnosis.

Objective To assess the relationship between type 2 diabetes and the risk of kidney cancer. Methods PubMed, Medline, CNKI and VIP were used to identify studies which regarded the relationship between type 2 diabetes and risk of kidney cancer up to July 2014. The relative risks (RRs) and the corresponding 95% confidence interals (CIs) were used to estimate the association between type 2 diabetes and the risk of kidney cancer through software STATA. Results 8 studies were included in this analysis. Compared to the popula-tion without type 2 diabetes, there was an increased risk of kidney cancer in the type 2 diabetes patients, the pooled RR (95%CI) was 1. 55 (1. 24,1. 92),P<0. 05. Conclusion Our meta-analysis suggestes that type 2 diabetes can increase the risk of kidney cancer.

Objective To select and identify human leukocyte antigen(HLA)-A2-restricted T-cell epitope within heparanase(Hpa),and to provide aeademic bases for peptide-based immunotherapy with malignant tumor.Methods The Hpa sequence was scanned for prediction of the immunogenic peptides-based CTL epitopes using the HLA-binding prediction software SYFPEITHI and BIMAS.Ten the affinity of candidate epitopes to HLA-A2 was evaluated by T2 binding test.Acfivation of T cell was assessed by ELIS-POT and cytotoxictiy by lactate dehydrogenase(LDH)release assay.Results of the six predicted nona-peptides,Hpa(310-318,FLNPDVLDI)showed high affinity of binding to HLA-A2 and led to IFN-γ secre-tion in vitro.Furthermore,Hpa(310-318) FLNPDVILDI could induce PBMC from a HLA-A2 positive healthy donor to lyse specifically HCC-LM6 and SW-480 cells which expressing both Hpa and HLA-A2.Conclusion The nona-peptide Hpa(310-318)FLNPDVLDI may be all HLA-A2-restricted CTL epitope.which is capable of inducing Hpa-specific CTL in vitro.
