Objective:To study the efficacy of prostaglandin E1 in the patients with diabetic nephropathy and its inhibition on inflammatory factors. Methods:Totally 86 cases of diabetic nephropathy from June 2013 to June 2015 in our hospital were selected,and according to the random number,they were randomly divided into the observation group and the control group. The control group was treated with the conventional dietary restriction and therapy regimen including lowering blood pressure and blood sugar. The patients in the observation group were given prostaglandin E1 additionally. After the treatment,24h urine protein quantity,serum creatinine and blood urea nitrogen and the other basic indicators of renal function and the contents of sICAM-1 and hs-CRP were detected. Results:After the treatment,the contents of 24h urine protein,serum creatinine,blood urea nitrogen, sICAM-1 and hs-CRP in the two groups were notably decreased when compared with those before the treatment,and the decrease in the observation groups was more significant than that in the control group,and the difference was statistically significant(P <0. 05). During the course of treatment,no obvious adverse reactions appeared in the two groups. Conclusion:Prostaglandin E1 in the adjuvant treatment of diabetic nephropathy patients shows better therapeutic efficacy and inhibition on inflammatory factors with higher security,which should be promoted in clinics.

Objective To investigate the effects of CHIR99021 and Wnt3a, Wnt/β-catenin signaling pathway acti-vators, on cardiac differentiation of mouse embryonic stem cells ( mESCs ) . Methods The embryonic bodies ( EBs) were formed through suspension culture method, CHIR99021 or Wnt3a was added into differentiated medi-um from day 2 to 5, named CHIR99021 group or Wnt3a group, respectively. In addition, there was a control group in which EBs were automatically differentiated. The expression levels of Brachyury, the mesoderm specific target gene, and Nkx2. 5, cardiac-precursor marker, as well as the transcripts of cardiomyocyte markers,α-myosin heavychain (α-MHC ) , cardiac troponin T ( cTnT ) and connexin-43 ( Cx43 ) were analyzed through quantitative RT-PCR. Besides, the cardiac-specific proteins including α-MHC, cTNT and CX43 were detected by immunofluores-cence and Western blot. Results The mESCs in every group did differentiate into cardiomyocytes. The expression of Brachyury was substantially augmented by treatment with CHIR99021 and Wnt3a, showing a peak of expression at day 7. Similarly, CHIR99021 and Wnt3a dramatically increased the expression levels of Nkx2. 5,α-MHC, cT-nT and Cx43 with the time of differentiation, with the expression of target genes in CHIR99021 group and Wnt3a group was greater than that in the control group and CHIR99021 group was higher than Wnt3 a group at day 15 ( P<0. 05, P < 0. 01 ). Western blot analysis suggested that the expressions of α-MHC, cTNT and CX43 in CHIR99021 group and Wnt3a group were greater than those in the control group, and CHIR99021 group was higher than Wnt3 a group at day 15 . Conclusion Both CHIR99021 and Wnt3 a could improve cardiogenesis from mESCs through activate Wnt/β-catenin signaling pathway at the early stage of differentiation while the former is better than the latter.

Objective To investigate the effect of psychological abuse in childhood on the personality of undergraduates with depression as well as its possible mechanism, and thus provide scientific evidence for the intervention of depression in undergraduates. Methods Particinants were 733 undergraduates from a university in Henan Province. They were surveyed with Center for Epidemiological Studies-Depression scale (CES-D), childhood experience of care and abuse questionnaire (CECA. Q) and Eysenck personality theory (EPQ). Results the correlation between maternal antipathy and introversion-extroversion of personality;psychological abuse in childhood had apparently positive correlation with the depression in undergraduates (r = 0. 257, r = 0. 304, r =0. 243, P＜ 0. 01) and that of childhood maternal neglect to psychoticism (β = 0.206, P＜ 0.01) were positive and significant. The standard regression coefficients of paternal neglect to introversion-extroversion (β= -0. 143, P＜0. 01)were negative and significant . The scores of childhood paternal antipathy and maternal antipathy explained that childhood paternal antipathy had indirect effect via adulthood neuroticism on the depression in undergraduates,furthermore, the indirect effect demonstrated 59.8% of the total effect. Conclusion This study suggests that the personality of undergraduates with depression is affected directly by psychological abuse in childhood, and adulthood personality may mediate the relation between childhood psychological abuse and adulthood depression.

Objective:To isolate monocytes from human peripheral blood mononuclear cells( PBMC) ,induce macrophages,and identify the function of macrophages.Methods:Monocytes were isolated from PBMC using magnetic activated cell sorting( MACS) anti-CD14 microbead.Sorted CD14+and CD14-cells were checked by flow cytometer to evaluate the efficiency of sorting.The sorted CD14+cells were cultured in IMDM media with 10%human AB serum and 10 ng/ml M-CSF for 7 days to generate macrophages,which were identified by morphological features and phagocytosis function.Results:A high purity of monocytes was obtained by MACS anti-CD14 microbead.The percentage of CD14+cells was 10% and 85.8% before and after sorting, respectively.The macrophages were approximately 40-45 μm in maximum diameter and had the fried egg colony morphological features after 7 days culture.The lymphoma ( Raji) cells were efficiently engulfed by macrophages.Conclusion: The high purity of CD14+monocytes is isolated from PBMC and monocyte-derived macrophages efficiently engulfed lymphoma cells.

Objective To systematically evaluate the consistency of sensitivity (SEN) and specificity (SPE) between positron-emission tomography (PET) /magnetic resonance imaging (MRI) and PET/CT in the diagnosis of lymphoma.Methods The databases,including PubMed,Cochrane Library,Chinese Biomedical Literature Database (CBM),CNKI,Wanfang and VIP,were retrieved till October 2016.The studies published the SEN and SPE of PET/MRI and PET/CT in the diagnosis of lymphoma were collected and selected based on inclusion and exclusion criteria by two reviewers independently.Then,data extraction and analysis were performed by two independent reviewers.Resnlts A total of 6 studies,including 221 cases of patients with lymphoma,wereincluded.Among the 6 studies,4 of them provided patients-based and site-based data (including one provided data about staging ofdisease),and 2 studies only provided site-based data (including one provided data about staging of disease).The results indicated thatboth PET/MRI and PET/CT can accurately detect the lesions in patients with lymphoma,and the locations and numbers of lesions found bythe two methods were almost the same.Additionally,PET/MRI and PET/CT had high SEN and SPE for detection of lesions in patientswith lymphoma.and had high consistency in the diagnosis of lymphoma.Condusion The SEN and SPE of PET/MRI were similar to those of PET/CT in the diagnosis of lymphoma.PET/MRI may become a significant method for diagnosing lymphoma.
