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.

The study is to prepare taste masking and enteric-coated clarithromycin granules by melting and fluid bed coating technology. Clarithromycin and matrix materials were melted at a certain temperature, and then made into particles by fluidized bed coating. X-ray powder diffraction and scanning electron microscopy were used to identify the crystal and morphology of drug loading granules. In vitro dissolution method was used for the observation of the drug release behavior. The results showed that the drug particles size range was 0.2 - 0.6 mm; the crystal form of clarithromycin in the granule did not change; enteric-coated granules accumulated release in 0.1 mol L(-1) hydrochloric acid in 2 h was less than 10%, while in pH 6.8 phosphate buffer in 1 h was more than 80%. The taste masking and enteric-coated clarithromycin granules not only have good taste masking effect, but also have a good release behavior. It is expected to have better clinical application.

Objective To discuss the anatomical and radiographic characteristics of acetabular fossa,and evaluate their value as a reference for achieving the anticipated inclination of the acetabular cup.Methods Sixteen adult normal pelvic specimens were studied.Central axis of acetabular fossa and its intersection with fossa edge and acetabular rim were marked.The radiographic appearance of the two intersections was evaluated.With radiographic templating,the relationship between the top of acetabular fossa and the central axis of acetabular cup at anticipated inclination was identified.Implantation of cementless acetabular cup was performed bilaterally on the pelvic specimens.The acetabular fossa was used as a reference for implantation on one side,and the acetabular positioning device was used on the other side.The discrepancy of acetabular inclination was recorded before and after operation in the two groups.Results Intersection of central axis of acetabular fossa with fossa top edge and acetabular rim corresponded to the most medial and lateral aspect of acetabular sourcil respectively on standard anteroposterior pelvic radiograph.There was close correlation between most medial aspect of acetabular sourcil and central axis of the acetabular cup at anticipated inclination of 40°±5°.For the group of using acetabular fossa as reference,the mean difference of inclination was 0.19°±3.14°(-6°-5°)before and after operation,and the discrepancy was 2.75°±2.89°(-2°-8°)for the control group.The difference between the two groups was statistically significant(t=-2.453,P=0.027).Conclusion In primary total hip replacement,if normal anatomy of acetabulum was found,the anticipated inclination of acetabular cup can be accurately obtained,based on the relationship between the top of acetabular fossa and anticipated inclination of acetabular cup on preoperative templating.
