Objective To evaluate the prognosis of the decompensated liver cirrhosis by means of MELD-Na score combined with serum cholesterol and endotoxin concentration.MethodsData of 156 hospitalized patients with decompensated liver cirrhosis was retrospectively analyzed.Patients were divided into survival and death group according to follow-ups at 6 months,12 months and 24 months.MELD-Na score was made among 156 patients by detecting relevant indicators.Serum cholesterol and cholesterol levels were measured,too.The relationship between decompensated liver cirrhosis prognosis and MELD-Na score combined with serum cholesterol and endotoxin concentration was analyzed.ResultsNinteen patients died at the follow-up for 6 months.Fifty nine patients died at the followe-up for 12 months.Seventy seven patients died at the follow-up for 24 months.There was significant difference on MELD-Na score,endotoxin concentration and serum cholesterol between the survival group and the death group (t =-9.68,-9.22,11.4,-4.65,-19.60,16.20,-20.0,-18.7,17.3,respectively,P ＜0.05).The best critical value of MELD-Na score to predicate death in patients with decompensated liver cirrhosis was 32 points.The risk of death would rise if MELD-Na score increased.The best critical value of plasma endotoxin to predicate death in patients with decompensated liver cirrhosis was ≥ 12 ng/L.The best threshold value of serum cholesterol to predict death in patients with decompensated liver cirrhosis was ≤ 1.70 mmol/L.ConclusionMELD-Na score,serum cholesterol and serum endotoxin were of higher prognostic value to judge the prognosis of patients with decompensated liver cirrhosis.

Purpose To identify whether serum-free culture can enrich breast cancer stem cells from MCF-7 human breast cancer cell line. Methods MCF-7 human breast cancer cell line by serum-free culture and serum culture technology were cultured, its cell mor-phology and growth pattern were observed by the inverted microscope. The expression of stem cell surface molecular makers CD24, CD44 was observed by the inverted fluorescence microscope and the flow cytometry, the proportion of different subpopulation cells was detected by the flow cytometry. At the same time, difference of the cell cycle was detected by the flow cytometry. Results The cell line cultured by serum-free culture grew in the form of suspended microspheres of different sizes in the medium, but the cell line cul-tured by serum culture grew in the form of monolayer adherent growth. There was no obvious difference in the expression of stem cell surface molecular makers CD44 between the suspended microsphere cells and the adherent cells, but the expression of CD24 in the sus-pended microsphere cells decreased compared to the adherent cells. The proportion of CD44 + /CD24 -/low phenotype cells in the suspen-ded microsphere cells and the adherent cells was (86. 93 ± 0. 53)% and (19. 98 ± 0. 62)%, respectively (P<0. 05), the proportion of CD44 + /CD24 + phenotype cells was (12. 68 ± 0. 59)% and (79. 90 ± 0. 57)%, respectively (P<0. 05). The proportion of mitotic cells in the suspended microsphere cells and the adherent cells was ( 18. 85 ± 2. 26 )% and ( 43. 91 ± 1. 81 )%, respectively ( P<0. 05), the proportion of quiescent cells was (64. 92 ± 2. 07)% and (39. 82 ± 1. 77)%, respectively (P<0. 05). Conclusion CD44 + /CD24 -/low breast cancer stem cells can be effectively enriched by the serum-free culture technology.

0.05).CONCLUSION:Pure red cell aplastic anemia appears after allogeneic hematopoietic stem cell transplantation in major ABO incompatibility between donor and recipient,which may lead to prolonged destruction of donor-derived erythrocytes and prolonged transfusion requirements.However,myeloid and megakaryocyte hematopoietic recovery,incidence of complications and survival rate are not influenced by ABO incompatibility.

Hepatic venous pressure gradient (HVPG) is the gold standard for the degree of cirrhotic portal hypertension and has limited use in clinical application, and therefore, there is an urgent need for noninvasive assessment methods for portal hypertension. This article introduces various serological, imaging, and elastography methods and combined diagnostic models and elaborates on the current research results and the advantages and disadvantages of each method. It is pointed out that in future, noninvasive diagnostic techniques may play a greater role in screening, monitoring, and risk stratification of patients with cirrhotic portal hypertension.

Regenerative therapy holds great promise in the development of cures of some untreatable diseases such as cardiovascular diseases, and pluripotent stem cells (PSCs) including induced PSCs (iPSCs) are the most important regenerative seed cells. Recently, differentiation of human PSCs into functional tissues and cells in vitro has been widely reported. However, although porcine reports are rare they are quite essential, as the pig is an important animal model for the in vitro generation of human organs. In this study, we reprogramed porcine embryonic fibroblasts into porcine iPSCs (piPSCs), and differentiated them into cluster of differentiation 31 (CD31)-positive endothelial cells (ECs) (piPSC-derived ECs, piPS-ECs) using an optimized single-layer culture method. During differentiation, we observed that a combination of GSK3β inhibitor (CHIR99021) and bone morphogenetic protein 4 (BMP4) promoted mesodermal differentiation, resulting in higher proportions of CD31-positive cells than those from separate CHIR99021 or BMP4 treatment. Importantly, the piPS-ECs showed comparable morphological and functional properties to immortalized porcine aortic ECs, which are capable of taking up low-density lipoprotein and forming network structures on Matrigel. Our study, which is the first trial on a species other than human and mouse, has provided an optimized single-layer culture method for obtaining ECs from porcine PSCs. Our approach can be beneficial when evaluating autologous EC transplantation in pig models.

Objective:To identify differentially expressed genes (DEGs) associated with the progression of synovitis in RA by using bioinformatics analysis and explore the effects of DMARDs such as methotrexate, tocilizumab and rituximab on the DEGs in RA synovium.Methods:RA expression profile microarray data GSE7307、GSE12021、GSE55457、GSE55235、GSE77298、GSE89408 were acquired from the public gene chip database (GEO), including 113 synovial tissue samples from RA and 70 healthy controls (HC). At the same time, synovial expression microarrays GSE45867, GSE24742 and GSE97165 after DMARDs treatment were obtained. These data included 8 samples treated with methotrexate, 12 treated with tocilizumab, 12 treated with rituximab and 19 treated with combined tDMARDs. R software was used to screen DEGs and Venn plots using gene ontology function enrichment and Kyoto encyclopedia of genes and genomes pathway enrichment analysis. Hub genes were selected by STRING online analysis tool and Cytoscape software.Results:Compared with HC, 797 DEGs were up-regulated and 434 DEGs were down-regulated in the synovial tissue of RA. These DEGs were mainly enriched in T cell activation, immune response-activating cell surface receptor signaling pathway. Using Cytoscape and cytoHubba to obtain 5 sets of DEGs based on the STRING database model, the degree algorithm screened out 10 hub genes: LCK, SYK, PTPRC, HLA-DRA, LYN, NCAPG, TOP2A, JUN, CXCR4, CCNB1. Methotrexate treatment significantly up-regulated 20 DEGs and down-regulated 30 DEGs. Rituximab treatment up-regulated 100 DEGs and down-regulated 55 DEGs. Tocilizumab treatment up-regulated 91 DEGs and down-regulated 317 DEGs. These altered DEGs were enriched in regulating cell adhesion, leukocyte-cell adhesion, leukocyte transfer, and insulin-like growth factor receptor signaling pathways. It was worth noting that after treatment, a total of 306 high-expressing DEGs were down-regulated, and 36 low-expressing DEGs were up-regulated.Conclusion:LCK, insulin-like growth factor receptor signaling pathway, etc. are the responsible molecular mechanisms and key pivot genes for the occurrence and development of RA, and the treatment of DMARDs, which are closely related to the response of RA to the treatment of DMARDs.
