0.40); ②The result of EFA had four factors: physical aggression, anger, hostility and substitution aggression. The range of factor loading was between 0.51 and 0.75; ③The Chinese version of BPAQ had a satisfactory reliability with a 0.92 test-retest reliability and the Cronbach’s ? was 0.84; ④There was significant gender difference in physical aggression, substitution aggression and the total aggression. Conclusion: The Chinese version of BPAQ is a reliable and valid instrument for measuring aggression of adolescents.

Objective:To evaluate the predictive value of pretreatment platelet-to-lymphocyte ratios (PLRs) in response to neoad-juvant chemotherapy and prognostic outcome in patients with International Federation of Gynecologists and Obstetricians (FIGO) Stag-es IB2-IIB cervical cancer. Methods:An investigation was conducted from January 2010 to December 2012 on 75 patients with FIGO Stages IB2-IIB cervical cancer, who underwent neoadjuvant chemotherapy and radical surgery in Changhai Hospital, Shanghai. A re-ceiver operating characteristic (ROC) curve was used to determine the best PLR cut-off value in predicting the response to neoadjuvant chemotherapy. The relationships between the pretreatment variables and the response to neoadjuvant chemotherapy were assessed in univariate and multivariate settings. The overall three-year survival rates were analyzed using the log-rank test and Cox regression mod-el. Results:The response to neoadjuvant chemotherapy was associated with PLR. At the threshold of 123.0, the PLR was 88.5%sensi-tive and 52.2%specific. Multivariate analysis showed that the low independent PLR predicted the response to neoadjuvant chemothera-py well. Based on the log-rank test, the three-year survival rate was lower in patients with PLR >123.0 than those with PLR <123.0 (59.8%vs. 82.4%), but no statistically significant differences were observed between them (P=0.116). Mono-factorial analysis showed that vascular invasion (a tumor that is>4 cm in diameter) and lymph node metastasis influenced the three-year survival rate. In the Cox regression model, only the lymph node metastasis was identified as an independent risk factor for poor prognosis (RR:5.375;95%CI:1.351-21.379; P=0.017). Conclusion: Pretreatment PLR is an easily measured, reproducible, and inexpensive marker of systemic in-flammation and thus shows a prognostic and independent predictive value for the response to neoadjuvant chemotherapy in cervical can-cer. However, pretreatment PLR is not a clinically significant factor for the assessment of cervical cancer prognosis.

BACKGROUND: Studies demonstrated that vertebral endplate can be remodeled during intervertebral disc degeneration.However,the relationship between morphology of the vertebral endplate and intervertebral disc degeneration remains poorly understood.OBJECTIVE: To explore the relationship between the morphology of the vertebral endplate and the lumbar disc herniation.METHODS: Forty cases without previous spine disorder and sixty-two cases symptomatic lumbar disc herinations lumbar vertebral were scanned by using spiral CT.Scan range was from superior L4 to superior S2.Scan protocols as below: 140 kV,345 mAs,FOV 160 mm,layer of thick 1 mm,pitch 1.0.Original images were carried through three-dimensional reconstructions using O2 image work station,W300,C80,ZOOM=1.5,Expand 1.Intervertebral disc maximum anteroposterior,transverse diameter,circumference,area and shape were measured based on curve planar reconstruction.RESULTS AND CONCLUSION: Endplate shape was strongly related to disc herniation(all the P value < 0.01).Endplate area was a less significant factor L4/5 in men and L5/S1 in men and females(P < 0.05).The shape of the intervertebral body endplate margin is an important factor contributing to the development of disc herniation at L4/5 and L5/S1.
