Objective To observe the impact of different culture conditions on the growth of the endothelial progenitor cells(EPCs) from rat peripheral blood. Methods Mononuclear cells obtained from rat peripheral blood were isolated by using density gradient centrifugation. According to the culture medium added with vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and the dishes were precoated with fibronectin or not, the mononuclear cells were divided into different groups and cultured under different conditions in vitro to compare the differences of the growth conditions. The different growth conditions were recorded and the result was calculated by statistics software. At last, the cells were identified by immunohistochemistry and immunofluorescence. Results The mononuclear cells from rat peripheral blood grew in the manner of keeping close to the wall in vitro. The cells and cell colonies cultured for 7 days hinted:under the same culture conditions, precoating FN was beneficial to the adherent proliferation of EPCs (t=4.43, P<0.05; t=3.70, P<0.05). Excluding the impact of fibronectin, growth factors could promote mononuclear cells differentiation to EPCs, indicating that growth factors enhanced proliferation of EPCs (t =-13.22, P<0.01; t =-10.96, P<0.01). Immunohistochemistry and immunofluorescence showed that, at day 4, 7, 10 of cells cultured, CD34 and CD133 expressions were increased gradually [(35.7±4.2)%, (60.1±3.8)%, (81.8±6.4)%; (3.2±0.9)%, (18.4±7.3)%,(32±3.8)%, respectively]; at day 14, both were decreased [(32.1±5.4)%, (1.9±2.7)%]; but Flk-1was increased at day 4, 7,10, 14 [(31.2±3.5)%, (40.6±5.3)%, (71.2±8.4)%, (81.5±4.1)%].Conclusions Fibronectin is conducive to adhesion and proliferation of EPCs. VEGF and bFGF play an important role in the differentiation of EPCs. The success culture of EPCs in vitro will provide a sufficient number of seed cells for its application in vascular tissue engineering, and offer new ideas for peripheral blood stem cell transplantation for the treatment of various diseases.

Objective To observe the expression and influence of SH2-B in hepatocarcinoma,and to investigate the molecular mechanisms of canceration in hepatocarcinoma.Methods By using SABC imunohis-tochemistry,the expressions of SH2-B were detected in 27 cases of hepatitis,29 cases of hepatocirrhosis and 47 cases of hepatocarcinoma.Hepatocarcinoma cell (HepG)2 with a low-expressed SH2-B was selected using immunofluorescence assay.There were 3 groups:the transfected group (transfected with pcDNA3.1 -SH2-B), the vector group (transfected with pcDNA3.1 )and the blank group (without transfection).After gene transfec-tion,SH2-B expression was detected by Western blotting;cell proliferation was measured by MTT assay;cell colony was counted by colony formation test;and cell cycle was analyzed by flowcy tometer.Results The posi-tive rate of SH2-B in hepatocarcinoma (95.7%)was significantly higher than 55.2% in hepatocirrhosis (χ2 =1 8.64,P <0.01 )and 25.9% in hepatitis (χ2 =40.01 ,P <0.01 ).After being transfected with pcDNA 3.1 -SH2-B,SH2-B expression dramatically increased in HepG2 cells.After cultured for 48 h,the average optical density value of the transfected group was 1 .1 2 ±0.1 9,obviously higher than 0.45 ±0.1 1 in the vector group (t =-31 .55,P <0.01 ),which indicated that cells proliferation was significantly enhanced after being trans-fected with SH2-B.The cell colony numbers of the transfected group was 1 66 ±1 4,significantly higher than
82 ±8 in the vector group (t =-20.33,P <0.01 )and 78 ±9 in the blank group (t =-1 9.64,P <0.01 ), which indicated that the cell colony numbers increased after being transfected with SH2-B.The S stage cells of the transfected group was (45.7 ±5.8)%,significantly higher than (1 9.4 ±4.7)% in the vector group (t =-20.33,P <0.01 )and (20.5 ±5.1 )% in the blank group (t =-34.69,P <0.01 ),which indicated that SH2-B could enhance promote cell cycle of HepG2 cells.Conclusion The expression of SH2-B in hepatocar-cinoma is high,and it may be involved in the canceration of hepatocarcinoma though promoting cell cycle,cell proliferation and cell transformation.

Objective:To summarize the clinical features and gene phenotype of children with spondyloenchondrodysplasia with immune dysregulation (SPENCDI) caused by ACP5 gene mutation. Methods:The medical data and genetic phenotype of a child diagnosed with SPENCDI in the Department of Pediatrics, the First Affiliated Hospital of Zhengzhou University in February 23, 2017 were analyzed retrospectively.Besides, " spondyloenchondrodysplasia" were taken as the search terms to perform the retrieval in CNKI, Wanfang Data, and PubMed, in an attempt to conduct the literature review.χ 2 test was used to compare the factors among children with different mutations. Results:The 4.5-year-old girl was admitted to hospital for complaint of " fever and chilblain-like rash" when she was 2 years old.She was diagnosed with systemic lupus erythematosus (SLE) concomitant with lupus nephritis.Methylprednisolone combined with cyclophosphamide, mycophenolate mofetil was used for the treatment.However, she experienced multiple infections, thrombocytopenia, limp, and growth retardation during the treatment.Genetic detection identified ACP5 gene compound hybrid mutation: c.779C>A and c. 770T>C.She was diagnosed with SPENCDI, and was subjected to follow-up.A total of 78 SPENCDI patients were retrieved from the databases, with various clinical manifestations of SPENCDI, commonly with skeletal involvement and immune phenotypes; 73.08% of the cases were positive for antinuclear antibodies, 57.69% of cases were positive for anti-double stranded-DNA antibodies and 34.62% of cases had neurological symptoms.In 58 cases, ACP5 gene mutations were detected, including 44 homozygous mutations and 14 compound heterozygous mutations.Patients with ACP5 gene homozygous mutation had a higher probability of consanguineous marriage in parents [56.82% (25/44 cases) vs.14.29% (2/14 cases)]; patients with ACP5 gene heterozygous mutation were more likely to develop SLE [64.29% (9/14 cases) vs.34.09% (15/44 cases)]( χ2=7.722, 3.992; all P<0.05). Conclusions:The majority of the ACP5 gene mutations are homozygous mutations in patients with SPENCDI, and heterozygous mutations are rare.The clinical manifestations of SPENCDI are various and complex, it is prone to develop autoimmune diseases, and there was no clear correlation between clinical features and gene phenotype in SPENCDI patients.
