Objective To investigate the genetic changes of FGR and TP73 in PTCL-NOS, in order to verify the results of our previous a-CGH study and to explore their role on the pathogenesis of PTCL-NOS. Methods A total of 34 cases, of which 19 cases were examined by a-CGH, were investigated by interphasedual-colour FISH using homemade site-specific probes of FGR and TP73 by using a labelling method of nick translation and commercial probe CEP1. Results In general, 7 of 34 (20.6 %) cases of PTCL-NOS showed genetic aberrations, of which 4 cases had changes on both of the loci of FGR and TP73, including 3 cases of amplification and 1 loss of heterozygosity (LOH), 1 case of FGR amplification and other 2 TP73 amplification only. CEP1 amplification was detected in 4 cases (11.8 %), simultaneously associated with FGR/ TP73 gene amplification. Kaplan-Meier survival analysis indicated there was a trend that the group with genetic changes had a poorer prognosis than the group of non-genetic changes, and so as the group of TP73 genetic changes compared with the group of TP73 non-genetic changes, although their was no statistical significance (P >0.05). Conclusion The outcome of this study partially verified the results of a-CGH, and aberration of lymphoma-related genes FGR and TP73, and the amplification of CEP1 may play a significant role in the pathogenesis of PTCL-NOS.

Objective Ultra-wideband (UWB) microwave imaging is one of the promising alternatives for breast tumor detection, which can provide the desired high resolution and high sensitivity. Methods For UWB microwave early breast tumor detection, a UWB antenna with small size and compact structure is generally desired. To meet the demands of UWB microwave imaging and detection, a novel compact UWB probe is developed and tested. The probe is a combination of an exponentially-flared TEM horn and a pyramidal back-cavity, where the pyramidal back-cavity is employed to block back and side radiation. To increase the operation bandwidth, a low-frequency compensation loop loaded with resistors and a dielectric material block at the throat of TEM horn are added to the probe. Results The compact probe is fabricated and tested by vector network analyzer E8362B, and the results demonstrate an operation frequency band ranging from 1.36GHz to 20GHz for return loss under -10dB. Conclusion The probe can meet the needs of UWB microwave imaging for the early breast tumor detection.

To ascertain whether heat shock gene expression could protect pulmonaryendothelial cell from hydrogen peroxide(H2O2)一indueed injury,the protective effect of HSPgene expression induced by pretreatment of bovine pulmonary endothelial eells(BPAECs)by heat shock (42 ℃, 2h)against lethal dose(lmmol?L(-1),45min) of H2O2一induced cyt-otoxieity was observed in vitro.It was found that BPAECs heat一shocked prior to exposureto H2O2(Immol?L(-1) 45min)showed significant decrease in H2O2一mediated incrementof LDH rdlease and TBARS production and had an obvious alleviation of H2O2一induccddecreased activities of catalase and superoxide dismutase. Further study showed thatcycloheximide, a protein synthesis inhibitor and Actinomycin D,a mRNA transcriptioninhibitor blocked the expression of HSP 70 and HSP 70 mRNA respectively.Both agentsprevented the cytoprotective effect of heat shock pretreatment against H2O2一mediatedBPAECs injury. The results suggested that HSP70 gene selectively translated after heat shockwas invoived in enhancement of eellular antioxidant mechanism and protected BPAECsagainst H2O2一induced injury
