0.05).The 2 -year and 3-year survival rates were 91.7 %,89.2 % and 85.8%,86.1% in all patients for either gr oup. The 2 -year and 3-year survival rates were 84.2%,81.8% and 72.9%,77.1% in p atients with positive axillary lymph nodes for the two groups, with the differen ces insignificant (Logrank test P=0.663, P=0.9 19).There were no differences in the 2-year and 3-year survivals for patients with stage Ⅲ and over receiving ch est wall irradiation or not and patients who received different doses of chest w all irradiation (Logrank test P=0.449, P=0.764 ). Conclusions Locoregional recu rrence is not reduced and survival rate is not improved by chest wall irradiatio n in this study. The prognostic impact of chest wall irradiation and the optimal target of radiotherapy remains to be substantiated by more randomized trials.

Objective To analyze the examination results of external quality assessment(EQA) at all levels of iodine deficiency disorders(IDD) laboratories in Henan province and the network operation to further standardize and improve the laboratory,and to provide reliable laboratory quality assurance for surveillance and control of IDD.Methods The examination results of EQA at all levels of IDD laboratories in Henan province were statistically analyzed in accordance with the National Reference Laboratory (NRL) of IDD (1999-201 1).Results The survey results showed that the provincial level laboratory was all qualified in testing urinary iodine and salt iodine in the past 13 years.In prefectural level,the laboratory response rates were 100.0％,and through participation in EQA,laboratory capacity had been significantly increased and stabilized.From 1999 to 2001,the passing rate of check up of urinary iodine was 22.2％ (4/18),72.2％ (13/18),94.4％ (17/18),respectively,and the rate was stable at 100.0％(18/18) from 2002 to 2011 except 94.4％ (17/18) in 2003.Since 2000,the prefectural level laboratory began to take part in the salt iodine EQA,and the laboratory response rate was 100.0％ (18/18) from 2000 to 2011.Except 88.9％(16/18) in 2003,the passing rate of check up of urinary iodine was 100.0％(18/18)from 2000 to 2011.In 2003 and 2004,6 to 7 county-level laboratories participated in the EQA of urinary iodine in Zhengzhou city,respectively,and all qualified.The number of county-level laboratories that participated in the salt iodine quality control network increased from 29 in 1999 to 148 in 2011.Response rate was 94.4％(68/72),96.7％(58/60) and 92.3％(144/156)in 2003,2006 and 2007,respectively,and the rate remained stable at 100.0％ in the remaining 10 years.In 1999,the passing rate was 69.0％ (20/29),then increased significantly,except 86.7％ (26/30) in 2001 and 84.6％(132/156) in 2007,the rates were all above 90.0％ in other years,especially in 2000 and 2009,the passing rates were both 100.0％.Conclusions The accuracy of test results of external quality controls and the normal operation of the network at all levels of laboratories is closely related to the IDD laboratory conditions and detection techniques.

OBJECTIVETo introduce the location and course of S1, S2 sacral nerve root tunnel and to clarify the significance of the anterior aspect of sacral nerve root tunnel on placement of iliosacral screw on the standard lateral sacral view.

METHODSFirstly the data of 2.0 mm slice pelvic axial CT images were imported into Mimics 10.0, and the sacrum, innominate bones, and sacral nerve root tunnels were reconstructed into 3D views respectively, which were rotated to the standard lateral sacral views, pelvic outlet and inlet views. Then the location and course of the S1, S2 sacral nerve root tunnel on each view were observed.

RESULTSThe sacral nerve root tunnel started from the cranial end and anterior aspect of the vertebral canal of the same segment and ended up to the anterior sacral foramen with a direction from cranial-posterior-medial to caudal-anterior-lateral. The tunnel had a lower density than the iliac cortex and greater sciatic notch on the pelvic X-rays,especially on the standard sacral lateral view, on which it showed up as a disrupted are line and required more careful recognition.

CONCLUSIONIt can prevent the iliosacral screw from penetrating the sacral nerve root tunnel and vertebral canal when recognizing the anterior aspect of sacral nerve root tunnel and choosing it as the caudal-posterior boundary of the "safe zone" on the standard lateral sacral view.

The severe fever with thrombocytopenia syndrome virus (SFTSV) is a new member in the genus Phlebovirus of the family Bunyaviridae identified in China. The SFTSV is also the causative pathogen of an emerging infectious disease: severe fever with thrombocytopenia syndrome. Using immunofluorescent staining and confocal microscopy, the intracellular distribution of nucleocapsid protein (NP) in SFTSV-infected THP-1 cells was investigated with serial doses of SFTSV at different times after infection. Transmission electron microscopy was used to observe the ultrafine intracellular structure of SFTSV-infected THP-1 cells at different times after infection. SFTSV NP could form intracellular inclusion bodies in infected THP-1 cells. The association between NP-formed inclusion bodies and virus production was analyzed: the size of the inclusion body formed 3 days after infection was correlated with the viral load in supernatants collected 7 days after infection. These findings suggest that the inclusion bodies formed in SFTSV-infected THP-1 cells could be where the SFTSV uses host-cell proteins and intracellular organelles to produce new viral particles.
