Objective To investigate the mobility of the lung tumors in order to guide the margin that CTV is to be expanded to PTV during stereotaetic radiotherapy for lung tumors.Methods Eighty-three lung tumom ineluded,in which 7 invaded the chest wall.1-2 gold marker(s)was/were implanted into or nearby the tumor.The motion of lung tumors in x(right-left),y(superior-inferior)and:(anterior-posterior)directions were measured via X-ray simulator system.One week later,1.25 mm thick of 16-slice spiral CT lung scan were taken.Apex,middle,and bottom of the lung were classified according to anatomic boderlines.Results No significant difference was detected among movements of apex,middle and bottom of the lung lesions in x axis direction((1.6±0.8),(2.6±1.1),(2.8±1.7)mm,respectively(F=1.76,P=0.179))and,y axis direction((2.0±1.3),(4.3±2.8),(4.0±2.0)mm,respectively(F=2.06,P=0.135))in 76 lesions of 63 patients.Significant differences were detected in:axis((2.7±0.8),(7.3±3.6),(12.0±5.3)mm(F=16.33,P=0.000)).The mobilities of the 7 lesions of 7 patients invading the chest wall were very small in all directions(0.9±0.7,0.7±0.7.and 2.0±0.6 mm,respectively).Motion amplitude did not correlate with the sex,age,height,weight and FEV1/FVC(r=-0.001-0.136.all P>0.05).Conclusions Motion amplitude of lung tumor due to breathing is associated with tumor loeation and status of chest wall invoivement.Identification of the mobile rules and the influencing factors is important for the internal margin set-up in lung tumor radiotherapy.

Objective To analyze the elonal gene rearrangement and complementarity determining region 3 (CDR3) Repertoire of TCR β-chain in fine needle aspiration biopsy (FNAB) specimens of peripheral T-cell lymphoma. Methods The TCR CDR3 region genes of 24 TCR Vβ subfamilies were amplified by utilizing RT-PCR technology, and the CDR3 size lengths of TCR β-chain were analyzed with genesean technology for 4 healthy individuals and 4 patients with peripheral T-cell lymphoma. The clonality of T cells presumed by spectratyping was further confirmed by CDR3 sequencing. Results TCR β-chain presented specific repertoire skewing in 4 cases with peripheral T-cell lymphoma, and only 1-4 TCR Vβ subfamily T cells were identified, respectively. Clonal expanded T cells, including mono, bioclonal and oligoclonal trend patterns, in one or more Vβ subfamilies were found in all cases. The mono expanded T cells have different CDR3 amino acid sequences. Conclusion Characteristic T cells cloning proliferation and selected usage of TCR Vβ subfamily T cells were found in 4 cases with peripheral T-cell lymphoma. The sequences of CDR3 in different TCR clone proliferation are different.

AIM:To investigate the effects of N-acetylcysteine (NAC) on acute lung injury induced by H9N2 swine influenza virus ( SIV) in mice.METHODS: BALB/c mice were used to establish the animal model of acute lung injury by nasal inoculation of H9N2 SIV.The mice were divided into control group (without SIV infection), H9N2 SIV group (inoculation of H9N2 SIV) and NAC group (inoculation of H9N2 SIV plus pretreatment with NAC).The pulmonary edema was evaluated by determining the lung wet weight /dry weight ( W/D) ratio.The pathological changes of the lung tis-sues were observed .The concontrations of TNF-α, IL-1βand IL-6 in bronchoalveolar lavage fluid ( BALF) were meas-ured.The virus titer, T-SOD activity, MPO activity and MDA content in the homogenate of the lung tissues were detected . RESULTS:Treatment with NAC decreased the morality of infected mice , and significantly prolonged the survival time of infected mice .The pathological changes of the lung tissues , the lung W/D ratio and the lung index were relieved when SIV infected the mice treated with NAC .Treatment with NAC significantly decreased the infiltration of inflammatory cells inclu-ding macrophages, lymphocytes and neutrophils in the BALF .The levels of TNF-α, IL-6, IL-1βand MDA and the activity of MPO were also decreased.Treatment with NAC also significantly increased the T-SOD activity.CONCLUSION: The protective effect of NAC on the acute lung injury mouse model is related to suppression of the oxidative stress and inflamma -tory responses .
