Esophageal cancer is one of the most high incidence of malignant tumors in China. However, the evaluation of chemoradiotherapy curative effect for esophageal cancer is lack of accurate and uniform criteria. In recent years, the imaging evaluation methods for chemoradiotherapy response in esophageal cancer have made some progress. The methods mainly include X-ray barium examination, endoscopic ultrasonography (EUS), computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography-computed tomography (PET-CT), and so on. Imaging examination has the advantages of safety, non-invasion and repeatability, and so on, which is a progressing tool for curative effect evaluation. Current status of the application of medical imaging which is used to evaluate esophageal cancer chemoradiotherapy curative effect were reviewed in this paper.

Objective:To investigate the characters of ERP in undergraduates with different trait anxiety during exam stress. Methods: By the State Trait Anxiety Inventory, one group of 15 undergraduates with high trait anxiety and another group with low trait anxiety were chosen from 200 participants in Band 4 College English Test. Their change of P3 were observed through NeuroScan 32 Channel ERP System during pre- exam and post- exam. Results: The amplitude of P3 of the group with low trait anxiety was enhanced while another group with high trait anxiety had no significant difference after exam; The latency of P3 of the group with low trait anxiety were decreased while another group with high trait anxiety had no significant difference after exam; There weren’t significant differences in amplitude and latency of P3 between high trait anxiety group and low trait anxiety group before exam; There were significant enhance of amplitude of P3 and decrease of latency of P3 in low trait anxiety group after exam as compared with high trait anxiety group. Conclusion: The result suggests different trait anxiety groups have different cognitive functions. When confronting with the same stress.

?Objective: To study the effects of endogenous bone morphogenic protein 2(BMP 2) and 6(BMP 6) in rat facial nerve after injury. Methods: Facial nerve trunk was cut and then anastomosed in 30 adult male Sprague Dawley rats,another 6 rats without operation were used as the controls. Every 6 rats were killed 6 ,72 h,1, 2 and 4 weeks respectively after operation and nerve specimens were immunohistochemically examined for BMP 2 and BMP 6 expression. Result:In the control nerve the gray level of BMP 2 and BMP 6 were 210.89?8.21 and 232.03?9.25 respectively. 6, 72 h,1, 2 and 4 weeks after operation the gray level of BMP 2 were 242.83?11.01,240.67?7.91,234.46?5.28,232.12?7.27 and 220.71 ?10.19;that of BMP 6 210.75?5.19,204.08?10.85,198,91?8.58,186.37?4.11 and 184.62? 8.45 ,respectively. Conclusion: BMP 2 may play a role in the early irritable actions when facial nerve was injured. However, BMP 6 might have functions in the regeneration of facial nerve during later period after injury.

Objective:To examine the influence of exam stress on the sustained attention of students with different levels of trait anxiety. Methods: With the State-Trait Anxiety Inventory (STAI), 10 students with high trait anxiety (high trait anxiety group, H group) and 10 with non-high trait anxiety (non-high trait anxiety group, NH group) were randomly sampled from 400 students taking the coming College English Test-Band 4 (CET-4). Their attention was measured with digit cancellation test and the event related potentials during the control phase (the period was chosen 2 weeks after the beginning of the semester and there was no examination in the following 3 months) and the stress phase ( from 2 weeks to 1 day before CET-4 examination). Results: The right cancellation number of the NH group was higher than that of the H group(F=8.178, P=0.007). During the control phase the P300 amplitude and latency were similar between the 2 groups (F= 0.125, 0.127, respectively;P= 0.728, 0.726, respectively). During stress phase the P300 amplitude of the H group was significantly lower than that of the NH group(F=12.913, P=0.002)and the P300 latency of the H groups was longer than that of the NH group(F=16.952, P= 0.001). In NH group, the P300 latency in the stress phase was significantly shorter than that of the control phase (F= 6.514, P=0.020). Conclusion: Exam stress has different influences on the sustained attention of people with different levels of trait anxiety, which suggests that people with high trait anxiety are the target population for stress management.

To investigate the role of AQP9 in brain edema, the expression of AQP9 in an infectious rat brain edema model induced by the injection of lipopolysaccharide (LPS) was examined. Immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR) analysis demonstrated that the expressions of AQP9 mRNA and protein at all observed intervals were significantly increased in LPS-treated animals in comparison with the control animals. Time-course analysis showed that the first signs of blood-brain barrier disruption and the increase of brain water content in LPS-treated animals were evident 6 h after LPS injection, with maximum value appearing at 12 h, which coincided with the expression profiles of AQP9 mRNA and protein in LPS-treated animals. The further correlation analysis revealed strong positive correlations among the brain water content, the disruption of the blood-brain barrier and the enhanced expressions of AQP9 mRNA and protein in LPS-treated animals. These results suggested that the regulation of AQP9 expression may play important roles in water movement and in brain metabolic homeostasis associated with the pathophysiology of brain edema induced by LPS injection.
