Objective To investigate the imaging features of aggressive angiomyxoma.Methods CT findings in 3 patients and MRI finding among one of them with pathologically proved aggressive angiomyxoma were retrospectively analyzed and the relevant literature were reviewed.Results In all the 3 cases,CT and MR imaging demonstrated a well defined mass arising from the pelvis,perineum or vulva.The tumours displaced but did not invade adjacent structures of the pelvic.In 2 cases,there was marked enhancement following injecting contrast materials or T_2WI with internal swirling pattern.Recurrent tumour in one case was of similar imaging features to the primary lesion.The small cystiform area could be seen inside the lesion in one case.Conclusion Aggressive angiomyxoma carries certain characteristics in CT and MRI manifestations.MRI is more excellent than CT in delineating the site,shape and the extent of these lesions.

Objective To define the normal reference values of acetabular index and Sharp angle through 2333 standard anterior-posterior pelvic radiographs. Methods In our study, 2333 normal anteriorposterior pelvic radiograph images with standard exposure were selected. All the images were diagnozed normal by two radiologists and two pediatricians according to the criteria of T(o)nnis. All subjects were without any neuromuscular diseases and congenital defoemity. The acetabular index was measure in the subjects between age 0 to 10 years, and the groups were divided monthly within 1 year and yearly between 1 to 10years. The Sharp angle was measure in the subjects after 10 years, and the groups were divided yearly in adolescence and decadely in adults. Normal values of each age groups and the correlation charts were completed according to statistical analysis. Results The mean acetabular index was 28.39° in neonates followed by a steep decrease in the first three months after born. It decreased to 22.17°in the 1st year, 12.80°in the 10th years and then kept constant. Acetabular index of the female was generally 1°-2°larger than that of the male with statistical significance. The mean Sharp angle was 46.72°in the 10th years, which decreased to 39.10°in the 18th years and 35.69°in elderly people. Another declination was observed after age 40.Generally no gender difference was observed. Conclusion Acetabular index and Sharp angle vary with age.They reflect a dramatic morphological change in the acetabulum before adulthood and stay constant afterwards. Gender difference is obvious in many age groups but not all. Normal reference ranges of both gender at all age groups should be considered in clinical evaluation.

AIM:Spondylolisthesis is a common spinal disease for adults but rarely found in children.In this study,the treatment effect of spondylolisthesis in 7 children with posterior pedicle screw system after 1 year was explored.METHODS:①Eight children patients with spondylolisthesis treated in Shengjing Hospital of China Medical University between January 1996 and December 2006 were selected including 4 males and 4 females.The average age was 12.25 years(range,8-14 years).According to Meyerding classification,7 cases were of stage Ⅰand one of Ⅳ.②Texas Scottish Rite Hospital(TSRH) posterior pedicle screw system was provided by Wego Ortho Co.,Ltd.,GB1Z type,titanium,No.200511028009.Of the 8 cases,4 were treated by TSRH posterior pedicle screw system,3 were treated via a Wiltse paraspinal approach with autogenous bone graft placed between the transverse processes of L5 and sacral ala in situ fusion,and 1 was not treated by operation.The informed consent of treatment was obtained from the patients.③The changes in the spinal radioactive imaging before and after operation,and the material and host biocompatibility were observed.RESULTS:①Seven of 8 cases were followed up.The mean time of follow-up was 56.6 months with a range from 13 to 111 months.②Three of 4 cases treated by TSRH were vertebral completely reduction with the stability of instrumentation about 75%(3/4),and the other one was partly reduction(about 85%).One person developed the progress again in the X-ray films at three weeks after operation.Three cases treated by Wiltse paraspinal approach with autogenous bone graft placed between the transverse processes of L5 and sacral ala in situ fusion healed well without the recurrence of lumbosacral spondylolisthesis and nonunion.CONCLUSION:TSRH is an efficient and safety option for the treatment of spondylolisthesis in children.

Objective To explore the association between rs7049105, rs647188, rs1333035 of chromosome 9p21 and the LAS among Chinese Han population of Changsha;to explore the association between rs7049105, rs647188, rs1333035 and the LAS among patients with evidence of cephalic and cervical vessel atherosclerosis. Methods The present study com?prised 229 LAS patients and 233 healthy controls. The 233 controls which we defined control group 1. In the controls, 150 (64.38%)controls with evidence of atherosclerosis were defined as control group 2, 83(35.62%)controls without evidence of atherosclerosis were defined as control group 3. The sample genotyping was detected using MALDI-TOF-MS. Results There was no polymorphism of rs647188 among case group and control group 1. There was no significant difference in the polymorphism distribution of rs7049105 and rs1333035 between the case group and control group 1 and 3 (P>0.05). There may be no significant different in the polymorphism distribution of rs7049105 between the case group and control group 2 . The rs1333035 was associated with risk of LAS among patients with evidence of cephalic and cervical vessel atherosclerosis (χ2=6.502,P=0.039). Conclusions The rs10757274 and rs7049105 polymorphism in the chromosome 9p21 may not be as?sociated with risk of LAS among Han population of Changsha. There may be no polymorphism of rs647188 among Han popu?lation of Changsha. The rs1333035 polymorphism may be associated with plaque rupture and thrombosis.

BACKGROUND:Sodium butyrate, a histone deacetylase inhibitor, can inhibit cell proliferation, and induce apoptosis and differentiation of various cancer cells. However, the role of sodium butyrate combined with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) on lung cancer stem cells remains unclear. OBJECTIVE:To explore the effect of sodium butyrate combined with TRAIL on biological behaviors of lung cancer stem cells. METHODS:Magnetic bead separation was used to separate lung cancer stem cells (CD133+) from human lung adenocarcinoma A549 cells. After the lung cancer stem cells were treated with simple DMEM/F12, DMEM/F12 containing sodium butyrate (5 mmol/L), TRAIL (50 μg/L) or sodium butyrate combined with TRAIL, the cell proliferation within 96 hours of culture was determined by MTT assay; the apoptosis within 24 hours of culture was measured by flow cytometry; the cell migration within 48 hours of culture was detected by cell scratch test; the expression levels of pluripotent transcription factors (Oct4, Sox2 and Nanog) within 48 hours of culture were detected using western blot analysis. RESULTS AND CONCLUSION:The CD133+ lung cancer stem cells were successfully enriched from human lung adenocarcinoma A549 cells. MTT assay showed that sodium butyrate and TRAIL significantly inhibited the proliferation of lung cancer stem cells (P< 0.05), and the combination effect was even stronger (P < 0.05). Results from flow cytometry analysis and scratch test showed that sodium butyrate or TRAIL induced apoptosis and inhibited cell migration of lung cancer stem cells (P < 0.05), and the combination of sodium butyrate and TRAIL showed a stronger effect (P < 0.05). In addition, the expression levels of Oct4, Sox2 and Nanog were significantly down-regulated by sodium butyrate (P < 0.05), TRAIL or sodium butyrate combined with TRAIL, and the combination effect was stronger (P < 0.05). In conclusion, sodium butyrate and TRAIL have synergistic effects on lung cancer stem cells, indicating a new way for treatment of lung cancer.

AIM: To compare the peripapillary retinal nerve fiber layer ( RNFL ) thickness and peripapillary topographic map's parameters between amblyopic eyes and non -amblyopic eyes in adolescent with anisometropic amblyopia by optical coherence tomography(OCT).
METHODS: Thirty - four juveniles with anisometropic amblyopia were selected. Peripapillary RNFL thickness and peripapillary topographic map were measured by frequency domain OCT with both eyes in all participants, and the differences between amblyopic eyes and non -amblyopic eyes were compared.
RESULTS: There was no significant difference in average thickness of peripapillary RNFL and in any other region of peripapillary RNFL. The disc area in amblyopic eyes was bigger than that in non - amblyopic eyes ( t =2. 8054,P= 0. 0263). The disc area in amblyopic eyes were significantly related to the thickness of nasal RNFL and the rim area(r= 0. 7592,0. 7501;P= 0. 0289,0. 0321).
CONCLUSION: There existed some difference in peripapillary structure between amblyopic eyes and non-amblyopic eyes in adolescent with anisometropic amblyopia.
