Objective:To investigate the radiosensitization and the cell-cycle of mild hyperthermia(≤42℃)on human pulmonary adenocarcinoma cell line SPC-A-1 in vitro. Methods: The human pulmonary adenocarcinoma cell line SPC-A were treated with radiation and the combination of radiation with mild hyperthermia. Radiosensitivity was determined by clonogenic assay and quantified by calculating the thermal enhancement ratio (TER). Flow cytometry was used to observe the cell-cycle. Results: Do, Dq calculated from the dose-response curve for radiation combined with 41.5℃ were 1.390 Gy, 1.426 Gy, whereas 1.693 Gy, 2.453 Gy for radiation alone, respectively. TER was 1.218. The proportion of cells in S phase was found to be 14.81% in the radiation group. The values, after 48 hours and 72 hours, with 6Gy radiation combined immediate 41.5℃ one hour mild hyperthermia, were 5.89% and 9.08%, respectively, versus 18.8% and 31.91% with 6 Gy radiation alone. Conclusion:Radiosensitization of mild hyperthermia in SPC-A-1 cells associated with the hyper-radiosensitization of the cells in S phase.

This study investigated the effect of arctigenin (Arc) on the cell activation, cytokines expression, proliferation, and cell-cycle distribution of mouse T lymphocytes. Mouse lymphocytes were prepared from lymph node and treated with Phorbol-12-myristate-13-acetate (PMA)/Ionimycin (Ion) and/or Arc. CD69, CD25, cytokines, proliferation and cell cycle were assayed by flow cytometry. The results showed that, at concentrations of less than 1.00 micromol x L(-1), Arc expressed non-obvious cell damage to cultured lymphocytes, however, it could significantly down-regulate the expression of CD69 and CD25, as well as TNF-alpha, IFN-gamma, IL-2, IL-4, IL-6 and IL-10 on PMA/Ion stimulated lymphocytes. At the same time, Arc could also inhibit the proliferation of PMA/Ion-activated lymphocytes and exhibited lymphocyte G 0/G1 phase cycle arrest. These results suggest that Arc possesses significant anti-inflammatory effects that may be mediated through the regulation of cell activation, cytokines expression and cell proliferation.

This study aims to investigate the genetic characteristics of BZLF1 gene and its promoter Zp of the epidemic strains in children with primary Epstein-Barr virus (EBV)-associated diseases. Total DNA was extracted from the peripheral blood of 134 children with EBV-associated infectious mononucleosis (EBV-IM) and 32 children with EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) who were admitted to Beijing Children's Hospital from 2006 to 2011. The EBNA3C, BZLF1, and Zp genes were amplified by PCR assay. Typing of EBV was performed according to the size of the amplification product of EBNA3C gene; the amplification products of BZLF1 and Zp genes were subjected to direct sequencing, and sequence analysis was performed using BioEdit 7. 0. 9. The results were as follows: (1) EBV-1 was present in 140 samples (97.2%, 140/144) and EBV-II in 4 samples (2.8%, 4/144). (2) Three BZLF1 genotypes and their 12 subtypes (including 6 newly found subtypes) were detected in this study; there were no significant differences in the frequencies of BZLF1-A and BZLF1-B between the children with EBV-IM and EBV-HLH (P = 0.083); BZLF1-A1 was the dominant genotype in children with EBV-associated diseases; t BZLF1-A mostly had three 29-bp repeats in the first intron of BZLF1 gene, and BZLF1-B mostly had 30-bp repeats (P = 0.000), with the number of repeats varying from 1 to 13. (3) Four Zp genotypes were detected in this study, including Zp-P, Zp-V3, Zp-V4, and Zp-V1; there were no significant differences in the frequencies of these Zp genotypes between children with EBV-IM and EBV-HLH (P = 0.272, 0.252, 1.0, and 1.0, respectively). (4) The linkage analysis of BZLF1 gene and its promoter Zp showed that BZLF1-A1 was highly associated with Zp-V3 (P = 0.000), while BZLF1-B4 with Zp-P (P = 0.000); EBV-I + BZLF1 A1 was highly associated with Zp-V3 (P = 0.000), while EBV-I+BZLF1-B4 with Zp-P (P = 0.000). The conclusions are as follows: (1) BZLF1-A1 is the dominant genotype in children with EBV-associated diseases; there are mostly 29-bp repeats in the first intron of BZLF1 gene for BZLF1-A genotype and 30-bp repeats for BZLF1-B genotype. (2) Zp-P and Zp-V3 are dominant Zp genotypes of EBV in children, which shared similar detection rates. (3) BZLF1-A1 is highly associated with Zp-V3, while BZLF1-B4 with Zp-P; EBV-I+BZLF1-A1 is highly associated with Zp-V3, while EBV-I+BZLF1-B4 with Zp-P.

Objective To explore the correlation between nurses′ preventive behavior against needle stick injuries and perception of risks, hospital safety climate as well as provide some references for strategy making. Methods In accordance with a multi-stage sampling method, questionnaires were used to collect data from 1 012 nurses in 8 level three class A general hospitals. Results The average scores of nurses′ preventive actions toward needle stick injuries and hospital safety climate were (3. 71 ± 0. 50) and (3. 91 ± 0. 53) respectively. Nurses with high perception of risks accounted for 67. 1%. In addition, the Spearman correlation analysis suggested that nurses′preventive behavior was negatively correlated with perception of risks (r= -0. 093,P<0. 01), while it positively correlated with hospital safety climate (r=0. 463,P<0. 01). Conclusions Clinical nurses should have further regulations for protective behavior against needle injuries. We can take measurements actively to reduce nurses perception of risks and create safety work climate that can be benefits for nurses taking favorable protective behavior and reducing the incidence of needle injuries.
