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.

objective To discuss the possible reasons responsible for the symptomrecurrence after operation for choledochocele, prevention and treatment. Methods By analyzing the symptom recurrent cases among 76cases of choledochocele who were treated in our hospital during the period from March 1966 to September 1997, we discuss the possible reasons responsible for the symptom recurrence after operation for choledochocele and its prevention and treatment. Result The possibility of symptom recurrence has no relationship with the age, sex and the type of the cyst. But it is closely related to the opportunity and method of operation (p

Objective To explore the effect of particulate matter (PM) 2.5 on the expression of pigment epithelium-derived factor (PEDF) protein in bronchial epithelial cells (BEAS-2B). Methods Human BEAS-2B were subcultivated, followed by low, medium and high concentrations of PM2.5 (25μg/ml, 50μg/ml, 100μg/ml) stimulation for 24 hours. The expression of PEDF protein in supernatant was ana-lyzed by enzyme-linked immunosorbent assay (ELISA), and the expression in BEAS-2B cells was detected by Western blotting. Results Compared with the control group, the expression of PEDF protein in supernatant and BEAS-2B cells induced by PM2.5 (25 μg/ml) in-creased, but no significance was found (t=-0.730, t=-1.840, P>0.05), and the expression induced by PM2.5 with the concentrations of 50μg/ml and 100μg/ml significantly increased (t>5.798, P<0.05). Conclusion PM2.5 with the concentrations of 50μg/ml and 100μg/ml could increase the expression of PEDF protein in a concentration-dependent manner both in supernatant and BEAS-2B cells.

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 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.
