AIM: To explore the effects of aflatoxin G 1(AFG 1 )on proliferation and TNF-? secretion of human peripheral blood mononuclear cells(HPBM) in vitro. METHODS: The effects of AFG 1 on proliferation of HPBM were analysed with flow cytometric (FCM) DNA analysis and MTT bioassay, while that on TNF-? secretion was detected with ELISA. RESULTS: FCM analysis revealed that 6 h after treatment, proliferation index(PI) of 1000 ?g/L AFG 1 treated HPBM was significantly higher than that of control. 24 h after AFG 1 treatment, stimulating effects on proliferation was found in HPBM treated with AFG 1 at 200 ?g/L and 1 000 ?g/L.Regression analysis showed that PI was postively correlated with the concentrations of AFG 1 in the concentration range from 0 to 1 000 ?g/L( r=0. 5122 and 0.5119 respectively,P

Objective To assess the value of magnetic resonance diffusion weighted imaging(DWI) and apparent diffusion coefficients(ADC) values of hepatic alveolar echinococcosis(HAE) in children.Methods 20 cases of children(≤14 years) with HAE were collected in this restrospective study.PNM staging was determined, the HAE peripheral area of DWI lesions with different P stages was observed, and the ADC value of the peripheral area was measured.The comparison of alveococcus lesions in different stages of DWI with continuous edge degree and ADC value difference was done to evaluate the growth activity.Results There were 5 cases of P1 lesions, 7 cases of P2 lesions, 2 cases of P3 lesions and 6 cases of P4 lesions.DWI features of peripheral area were as follows: High signal ring band between HAE lesion edge and adjacent normal hepatic parenchyma was observed.P1 lesions showed almost complete obviously high signal peripheral area, indicating the most active proliferation, P2 and P3 lesions of peripheral area were continuous and with high signal, and still had obvious growth activity.P4 lesions of peripheral area were not continuous, while the signal decreased, indicating the activity also decreased.The highest ADC value was detected in P1 lesions group of and the ADC value of P2 lesions group were lower than P1, and the ADC value of P4 lesions group were the lowest.P3 lesions samples were too small and thus no statistical analysis was done.Differences of ADC value between the three groups were statistically significant (P<0.05).Conclusion DWI image features could be used to assesse the growth activity of HAE in children with different stages to a certain extent.ADC values measurement provides important reference value for evaluating the growth activity at various stages of the lesions.

Objective To understand the infection situation of human T lymphocyte virus(HTLV) among blood donors in Zhongshan area.Methods Blood samples from 40 874 blood donors in Zhongshan from March to December 2016 were screened for HTLV antibody by using,enzyme linked immunosorbent assay(ELISA).The positive samples were reexamined two times,and specimens with positive results of reexamination were detected by using immunohistochemical method(CLIA).Then the positive samples were confirmed by Western blot(WB),and confirmed positive samples were judged as infection.Results Of all 40 874 cases of voluntary blood donors,21 cases were positive with HTLV antibody detected by ELISA,the positive rate of ELISA was 0.05%.Five cases were positive detected by CLIA method.One case was confirmed by WB,and the infection rate was 0.002 4%.Conclusion In order to ensure the safety of blood transfusion and reduce blood transfusion infection of HTLV,it might be necessary to perform HTLV screening in first-time blood donors in Zhongshan area.

Objective To construct a prostate cancer specific oncolytic adenovirus armed with a fusion protein gene , PSA-IZ-CD40L, and to evaluate its oncolytic efficiency and immune activation ability in vitro.Methods Prostate Specific Antigen (PSA) gene, CD40L-N and CD40L-C genes were obtained from cDNA of LNCaP cells and Jurkat cells using poly-merase chain reaction (PCR) or nested-PCR, respectively.PSA,Linker,CD40L-N and CD40L-C were linked sequentially to generate fusion protein gene PSA-IZ-CD40L (PL) by overlapping PCR.Then, prostate specific oncolytic adenovirus PL-carrying gene, Ad-PL-PPT-E1A,was constructed using the oncolytic adenovirus system , which was based on Adeasy sys-tem.PC3M cells were infected by Ad-PL-PPT-E1A at serial multiplicity of infection (MOI), and the apoptosis was detec-ted by flow cytometry at several time points post-infection.For immune activation detection , PC3M cells were infected with Ad-PL-PPT-E1A at a MOI of 50, and the cell lysate was collected at 48 h post-infection.Peripheral blood mononuclear cells derived (PBMCs) from healthy donors were stimulated by the lysate from PC 3M cells or Ad-PL-PPT-E1A infected PC3M cells before proliferation was assayed using cell counting kit-8 (CCK8).Results Fusion protein gene, PSA-IZ-CD40L, was successfully constructed and cloned into the prostate cancer specific adenovirus to generate Ad -PL-PPT-PL. The expression of E1A and PL protein could be detected by reverse transcription PCR and Western-blotting.Cytopathic effect was observed in PC3M cells infected with Ad-PL-PPT-E1A.Furthermore, the apoptosis rate reached 70.67% ± 2.98%at 48 h post-infection with 200 MOI Ad-PL-PPT-E1A.Compared with the lysate of PC3M cells, that from Ad-PL-PPT-E1A infected cells could promote the proliferation of PBMCs .Conclusion We have constructed a prostate cancer spe-cific oncolytic adenovirus armed can fusion protein gene PL , Ad-PL-PPT-E1A, which could kill PC3M cells effectively and enhance the proliferation of PBMCs in vitro.

Objective To study the effect of heavy ion radiation on proliferation and apoptosis of human peripheral blood derived T lymphocytes and the mechanism .Methods T lymphocytes were isolated from heparinized whole blood samples by density gradient centrifugation using Ficoll before being irradiated with heavy ion beams 12 C.The accumulated absorbed dose (dose-rate values=0.5 Gy/min, and meanLET=29 keV/μm).12 h and 24 h post-infection, total RNA of T lymphocytes was isolated , and the apoptosis related gene expression , including Bcl-2, Bax, Caspase3, Caspase8 and Caspase9, was detected by RT-RT-PCR.24 h and 48 h after irradiation, the proliferation was analyzed by CCK 8 kit.The cell apoptosis was detected by flow cytometry after being labeled with AnnexinV-PE/7-AAD or AnnexinV-FITC/PE.The expression of Bcl-2, Bax and Caspase3 was also assayed by RT-PCR.Results Data showed that heavy ion radiation could inhibit the proliferation of T lymphocytes obviously , and the inhibition ratio in cells that received 2 Gy dose was much high-er than in cells that received 1 Gy dose.Furthermore, heavy ion radiation promoted the apoptosis of T lymphocytes signifi-cantly.The results of RT-PCR showed that the mRNA expression of Bcl-2 was down-regulated in heavy ion radiation T lym-phocytes while the expression of Bax and Caspase 3 was up-regulated.Conclusion Heavy ion radiation can inhibit the pro-liferation and promote the apoptosis of human peripheral blood derived T lymphocytes .
