Peroxiredoxins(Prxs) are a family of antioxidant protein that have been identified in prokaryotes and eukaryotes. As antioxidants, Prxs protein contains an active site cysteine that is sensitive to oxidation by H 2 O2, eliminate active oxygen that exist in normal tissues and cells, protect cells from oxidative damage induced by reactive oxygen species ( ROS). Prxs protein is a known free radical scavenger, and has been shown to play a role in several diseases. In this review, recent advances on the study of Prxs protein family and tumor related diseases are reviewed, which is expected to provide new ideas for the diagnosis and treatment of the related clinical diseases.

Objective To determine the serum levels of B cell activating factor-receptor(BAFF-R)in patients with primary Sj(o)gren's syndrome(pSS)and investigate the role of BAFF-R in the pathogenesis of pSS.Methods The serum concentration of BAFF-R was measured by ELISA in 120 patients with pSS and 62 age-and sex-matched normal controls.Results The median level of serum BAFF-R was(692.7 ± 536.9)ng/L in pSS and (279.7 ± 186.9)ng/L in healthy controls.The serum level of BAFF-R in the pSS was significantly higher than normal controls(P ＜0.01).Higher level of BAFF-R was associated with higher level of IgG(r =0.429,P ＜0.01).Serum level of BAFF-R had no correlation with IgA,IgM,C3,C4,RF,ESR and CRP.BAFF-R level was markedly increased in patients with positive ANA,anti-SSA,anti-SSB antibody compared with those with negative antibody.Conclusion The serum BAFF-R level was significantly elevated and correlated with the level of immunoglobulin and autoantibodies.BAFF-R play certain role in the pathogenesis of pSS.

Felty syndrome is a rare disorder that involves rheumatoid arthritis,a swollen spleen,de-creased white blood cell count,and repeated infections.This article analyze the clinical characters of this disease.

Objective Toinvestigatetheclinicalfeaturesandsurgicalprognosisofmoyamoya syndromeinchildren.Methods Theclinicaldataof12childrenwithmoyamoyasyndromeadmittedto the 307th Hospital of People′s Liberation Army from December 2002 to October 2013 were analyzed retrospectively. Eleven of them underwent encephalo-duro-arterio-synangiosis (EDAS). A total of 550 children with moyamoya disease in the same period were used as a control group. The clinical characteristics and surgical efficacy of the children with moyamoya syndrome were summarized and concluded by comparing the clinical data of the two groups,including sex,age of onset,initial symptom,progress symptoms, Suzukiinstallments,imagingfeatures,andsurgicalefficacy.Results Themaleandfemaleratioof the children with moyamoya syndrome was 1∶2. Their mean age of onset was 12 ± 5 years old. There were significant differences in the initial symptom (cerebral infarction and cerebral hemorrhage )and disease progress between the children with moyamoya syndrome group and the control group (5/12 vs. 14. 5%[80/550], 3/12 vs. 61. 8%[340/550],and 5/12 vs. 8.7%[48/550],respectively;all P<0. 05). Within the follow-up period,of the 11 children underwent EDAS,7 cases had no further attack,and 4 cases were improved significantly. There was significant difference in the modified Rankin scale (mRS)between the beforeandaftersurgery(0[0,1]vs.2[1,2];P<0.05).Conclusions Theclinicalfeaturesofthe children with moyamoya syndrome have some differences with those with moyamoya disease. Timely and effective EDAS treatment may effectively prevent disease progression and improve the prognosis of patients.

Objective To explore the short axial strain of left ventricle in patients with atrial septal defect(ASD)before and after the transcatheter closure by using two-dimensional speckle tracking imaging (2D-STI).Methods A total of 30 patients with ASD underwent echocardiography before and after the transcatheter closure.The procedure was performed to obtain the peak of circumferential strain(Sc)and radial stain(Sr)of left ventricle by 2D-STI.Thirty healthy volunteers were enrolled as controls.Results ①Compared with the control group,regional myocardial Sc of ASD group decreased(P <0.05).Sc of anterior septum (AS),anterior wall (AW),laterior wall (LW)and posterior wall (PW)increased (P <0.05)at 2-days after the transcatheter closure and those parameters were higher than control group.At the six-months after the transcatheter closure,those parameters reduced to the normal level (P <0.05).Sc of inferior wall (IW)and mid-posterior septum (MP-Sept)increased to the normal level at 2-days after the closure surgery (P <0.05).②Compared with control group,regional myocardial Sr of ASD group decreased(P <0.05 ) except PW,two-days after the transcatheter closure these parameters increased to the normal level.Sr of PW in ASD group increased compared with control group(P <0.05),and there were no statistical changes at 2-days after the transcatheter closure.Sr of PW in ASD decreased (P <0.05 )to normal level until 6-months after the transcatheter closure.③ Global circumferential strain (GCS)of left ventricular in ASD group were lower than control group (P <0.05 ).At two-days after undergoing transcatheter closure the GCS increased (P <0.05)and those parameters were higher than control group (P <0.05).Six-months after the transcatheter closure those parameters reduced to the normal level (P < 0.05 ).There were no statistical differences of left ventricular global radial strain (GRS)between control group and ASD group. However,the GRS of ASD group increased (P < 0.05 )and those parameters were higher than control group (P <0.05)after 2-days undergoing the transcatheter closure.At six-months after the transcatheter closure those parameters were reduced to normal level (P <0.05 ).Conclusions 2D-STI can quantitative evaluate left ventricular circumferential strain and radial strain in patients with ASD before and after the transcatheter closure.

Objective To investigate the effectiveness and feasibility of cardiovascular computed tomography angiography(CTA) in 128-slice DSCT with low tube voltage and low dosage contrast media in children with tetralogy of Fallot (TOF). Methods Forty patients with TOF were randomly divided into group A and group B by random number table method, patients in group A received a conventional scan with 80 kVp and contrast media of 1.2 ml/kg, patients in group B, 70 kVp and contrast media of 1.0 ml/kg were used. The injection time of the two groups were both fixed for 12 s. CT attenuation, image noise and signal-to-noise ratio (SNR) of ascending aorta, the main pulmonary artery, left ventricle and right ventricle were quantified. Radiation dose and volume of the contrast medium were recorded. Subjective image quality was assessed by two radiologists in consensus. The Student's t test was performed to analyse the differences between the two groups regarding CT attenuation, image noise, SNR, radiation dose and volume of the contrast medium. The image quality scores between the two groups were compared by using the Mann-Whitney U test. Results No significant difference was found in the attenuation, noise, SNR between the two groups in the same evaluated anatomic regions and no significant difference was found in the image quality. Effective dose (ED) was(0.17±0.05),(0.13±0.04)mSv respectively, there was significant reduction in group B than that in group A (t=2.48, P=0.019). The consumed iodine amount was(10.00±1.84),(8.29± 1.45) ml respectively, there was significant reduction between the two groups (t=2.89, P=0.007). Conclusions In children with TOF, the cardiovascular CTA with diagnostic quality can be adequately acquired with low tube voltage (70 kVp) and low concentration contrast media (1.0 ml/kg), there is significant reduction in radiation dose and contrast medium amount.
