Objective:Recently,selenium was used for the treatment of Graves disease. However,there has been no reports that selenium affected the immune function of Graves disease at the cellular level so far. It is reported the effect of sodium selenite on Treg cells in peripheral blood mononuclear cells in patients with Graves disease in the present study. Methods:AFS were used to detect the level of serum selenium;PBMC( Peripheral blood mononuclear cells) were extracted,then,cultured with sodium selenite. Foxp3 mRNA expression was tested by Real-time fluorescence PCR,and ELISA was used to detect the secretion of IL-35. Results:The serum sodium selenite levels of GD group are significantly lower than the HC group;The expression of Foxp3 mRNA and secretion of IL-35 are both increased. Conclusion:It shows sodium selenite could improve the state of immune disorders by recovering the function of Treg cells.

Objective To evaluate the diagnostic value of urine-based prostate cancer antigen 3 ( PCA3 ) score in detecting prostate cancer during initial prostatic biopsy .Methods Urine was collected after digital rectal examination ( DRE) ( three strokes per lobe ) from 248 men before prostate biopsy .The specimens were collected between January 2010 and December 2012.The expression of PCA3 mRNA and prostate specifc antigen (PSA) mRNA was determined by quanti-tative real time polymerase chain reaction ( qRT-PCR ) .PCA3 scores were calculated by PCA 3 mRNA/PSA mRNA × 1000 .The ability of the PCA3 score to predict the biopsy outcome was assessed with AUC-ROC analysis and compared with the serum PSA levels.Results The rate of positive prostate biopsy was 32.3%(80 patients with positive prostatic biopsy versus 168 patients with negative prostate biopsy ) .PCA3 scores were significantly higher in patients with positive biopsy than in those with negative biopsy results (P<0.001).The ROC curve analysis demonstrated that the area under the ROC curve (AUC) of serum total PSA (tPSA), PCA3 score and the duplex model combining tPSA and PCA 3 score was 0.620, 0.693 and 0.724, respectively.Further analysis of the diagnostic performance of PCA3 score revealed that at a cut-off of 90.2456, the sensitivity was 67.5%and the specificity was 61.9%for discriminating positive biopsy from negative biopsy. The duplex model combining tPSA and PCA 3 score represented a better approach than tPSA alone in PCa diagnosis by pros-tatic biopsy (P=0.011), but there was no statistically significant difference between tPSA and PCA 3 score (P=0.160). In addition , a comprehensive diagnostic model based on multiple risk factors of prostate cancer combined with PCA 3 score could further improve the predictive accuracy of prostate cancer .Conclusion PCA3 could be a good predictor of prostate cancer in initial prostate biopsy in Chinese population .The comprehensive diagnostic model can improve the diagnostic potency .Further large-scale multicenter studies in China are needed to confirm our findings .

Objective To explore clinical effect and safety of intermittent androgen suppression treatment of advanced prostate cancer in elderly patients.Methods 78 patients with advanced prostate cancer were enrolled,and randomly divided into the observation group and the control group (n=39 each).Patients in observation group were treated with intermittent androgen suppression treatment.Patients in control group were treated with persistent androgen suppression treatment.Results The time of therapy was much longer in observation group than in control group (P＜ 0.001).Quality of life was better in observation group than in control group (P＜0.05).The incidences of adverse reactions including anemia,fever and abnormal liver function were lower in observation group than in control group (all P＜0.05).Conclusions Intermittent androgen suppression treatment prolongs time to androgen-independent progression,improve the quality of life,reduce drug dosage and the incidence of adverse reactions in the treatment of advanced prostate cancer in the elderly.

Background and purpose:The patients with aggressive lymphoma who have a poor prognosis and unlikely to be cured with conventional chemotherapy. This study was aimed to evaluate the effect of high-dose etoposide in mobilization followed auto-SCT in treating refractory lymphoma. Methods:40 patients [median age 33 (13-61) years] with refractory non-Hodgkin’s lymphoma (NHL, n=32) or Hodgkin’s lymphoma (HD, n=8) received high-dose etoposide [VP16 10-15 mg/(kg·d)×2 d] in mobilization in our center. Remission status prior to mobilization was PD (n=40). The use of such granulocyte colony-stimulating factor [G-CSF, 5-10μg/(kg·d)] mobilized peripheral blood stem cells (PBSC) after high-dose etoposide until the end of leukapheresis. Peripheral blood stem cell was collected and frozen in-80℃refrigerator. All these patients received auto peripheral blood stem cell transplantation (auto-PBSCT). Conditioning regimen was BEAM (n=19, 47.5%) or CBV (n=21, 52.5%). Results:Twenty-eight pa-tients (70%) were assessable for response after high-dose etoposide at a median pretreatment time of 39 days (range 17-172 days), 12 patients (30%) had no response. Median follow-up of 28 (4-66) months, 16 patients (40%) reached CR after auto-PBSCT. Fifteen of the 28 patients (53.6%) who had response to high-dose etoposide reached CR, 4 patients (14.3%) reached PR, 9 patients (32.1%) succumb to progression of disease. One of the 12 patients (8.3%) who had no response to high-dose etoposide reached CR, 1 patients (8.3%) reached PR, 10 patients (83.4%) succumb to progression of disease. The estimated 1-year OS and EFS were 69%and 56.7%respectively, 2-years OS and EFS were 63%and 52%respectively. The prognosis of the patients who had no response to etoposide was poor. The estimated 1-year OS and EFS were 25%and 16.7%respectively. Two group of comparison differences have statistics signiifcance (P<0.01). Conclusion: High-dose etoposide could be used in refractory lymphoma as rescue therapy in mobilization. It can increase the EFS and OS of patients who had response. The hematopoietic stem cells collection and hematopoietic reconstitution are not affected by etoposide.

Objective To investigate the effects of hyperbaric oxygenation(HBO)therapy on serum con- centrations of soluble intercellular adhesion molecule-1(slCAM-1),soluble vascular cell adhesion molecule-1(sV- CAM-1),soluble E-selectin(sE-selectin)and matrix metalloproteinase-9(MMP-9)in patients with aeute cerebral infarction and their clinical implications.Methods One hundred and twelve cases of cerehral infarction in the ca- rotid artery system were assigned into two groups.Patients in the routine treatment group(RT group,n=62)were treated with routine clinical treatment regime,whereas those in the HBO group(n=50)were treated with H BO ther- apy in additioo to routine clinical treatment.Thirty age- and sex-matched normal subjects were recruited and served as controls.The serum concentrations of sICAM-1,sVCAM-1,sE-selectin and MMP-9 were measured hy using ELISA method before and 10 days after treatment.The assessment of neurological deficits using National Institutes of Health Stroke Scale(NIHSS)score was conducted before treatment,and at 10 and 30 days after treatment,and the therapeutic efficacy was evaluated.Results The concentrations of sICAM-1,sVCAM-1,sE-selectin and MMP-9 of the patients were significantly higher than those of the control subjects.These parameters were all decreased signifi- cantly after treatment in the two patient groups.Moreover,these parameters were lower in the HBO group than those in the RT group after treatment.The NIHSS scores of HBO group were significantly lower than that of the RT group at the 30th clay post-treatment.The effective rate of HBO group was higher than that of RT group.Conclusion HBO therapy can decrease the serum levels of sICAM-1,sVCAM-1,sE-seleetin and MMP-9,which might be one of the mechanisms of HBO in the treatment of cerebral infarction.

Objective To explore the changes of plasma brain natriuretic peptide(BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP)of sepsis combined with myocardial injury in newborns.Methods According to neonatal sepsis treatment program,45 cases of sepsis newborns in NICU of the Second Hospital in Lanzhou University from Jul.2007 to Jun.2008 were collected.According to the myocardial injury diagnostic criteria,45 cases neonatal sepsis were divided into myocardial injury group(n=22) and non-myocardial injury group(n=23).Myocardial injury group was also divided into congenital heart disease group and non-congenital heart disease group accor-ding to echocardiography.At the same time,30 healthy newborns were collected as healthy control group.Every newborns were tested the level of plasma BNP,NT-proBNP,creatine kinase-MB(CK-MB) and cardiac-troponin I (cTnI).Results There were significant difference between myocardial injury group,non-myocardial injury group and healthy control group in the levels of plasma BNP,NT-proBNP,CK-MB and cTnI,those in congenital heart disease group were higher than those in non-myocardial injury group and the healthy control group(Pa0.05).Conclusions BNP and NT-proBNP can be early used to diagnose myocardial injury and heart failure of neonatal sepsis associated with CK-MB and cTnI.In NICU,infants with sepsis should normally test BNP and NT-proBNP in order to early diagnose myocardial injury of neonatal sepsis.

Objective To observe the effect of transplanting the adipose-dervived stem cells(ADSCs) on free radical metabolism and immune function of rat aging model induced by D-galactose from fasiaology perspective;to explore a new method for anti-aging. Methods The ADSCs were cultured in vitro. Thirty male SD rats were randomly divided into 3 groups: normal control group(A), aging model group(B) and treat group(C). Ten rats in each group. Rats in B and C groups were injected D-galactose continually into make the sub-acute aging model rats.After 8-week injections of D-galactose;R3ats in group C were injected ADSCs(3×10~6/ml) through caudal vein. After 2-week transplantions of ADSCs, T-SOD, CuZn-SOD, MDA, NO, IL-2 and spleen index levels in serums of each group were detected and compared among the three groups. Results Compared with the A group, the SOD, NO, IL-2 level and spleen index in serum in group B decreased significantly, while the contents of MDA increased significantly. Compared with group B, the SOD, NO, IL-2 level and spleen index in serum in group C had been improved, and the contents of MDA decreased significantly. Conclusion Transplanting ADSCs can improve the antioxidant ability and strengthen the cellular immune function of aging rats.Further more, it can delay the ageing procedure induced by D-galactose in rats.
