Objective To establish the measuring methods and relevant influencing factors of liver zone speed index (ZSI) by sound velocity tissue quantification (SVQ) technology in healthy subjects.Methods Liver ZSI were obtained in 49 healthy volunteers using SVQ technique with Zonare Z.one Ultra system.In the first 15 subjects,ZSI were acquired at four positions (superficial and deep parts of right lobe,superficial and deep parts of left lobe).Then the achievement rate in different position of liver was calculated to select the suitable measuring position.The reproducibility was analyzed with intra-group correlation coefficient(ICC).The last 34 healthy subjects received ZSI measurements in the appropriate position only.The reference value of ZSI was calculated using x-± 1.96 s.Results It was stable to measure values of ZSI with SVQ technique.The achievement rate was higher in right lobe with being 1 cm below the liver capsule for the optimal measuring point.There was no significant difference of ZSI value between male and female groups.There was no significant correlation between age and values of ZSI while a significant negative correlation was found between body mass index (BMI) and values of ZSI (r =-0.63,P =0.000).The reference value of body mass index between 18.5-23.9 kg/m2 was 5.67-36.29 m/s.Conclusions ZSI values of liver measured with SVQ technique shows a good stability and may be a new promising method for assessment of liver elasticity quantitatively.

Objective To evaluate the incidence of nasopharyngeal hemorrhage after radiotherapy of nasopharyngeal carcinoma (NPC) in order to adjust adequately the dose of fractionated stereotactic radiosurgery (FSRS). Methods Eighteen NPC patients were treated by FSRS following conventional radiotherapy of D T65～74?Gy. Of them, 5 patients (T 4) with uncontrolled lesions received a boost dose of 24～40?Gy/6～8 f and 13 patients (T 2～3 ) with local recurrence received their second course of treatment with different regimens. Group A: 8 patients received routine radiotherapy 30～40?Gy followed by FSRS 24～30?Gy/6～9 f; Group B: 5 patients received FSRS 40～42?Gy/6～8 f alone. Results The frequency of nasopharyngeal hemorrhage was 3/5 for skull base invasion (T 4 ) lesions. The incidence of morbidity for re radiation after local recurrence of T 2～3 tumor was 1/8 in Group A and 1/5 in Group B.Conclusions The frequency of nasopharyngeal hemorrhage is high in skull base invasion by NPC (T 4).Therefore the dose of FSRS combined with conventional radiotherapy should be limited when re treating local recurrence of NPC.

Objective To analyze the behavioral characteristics and mental health status for patients with chronic hepatitis B,to explore the correlation between them and analyze the influence of behavioral characteristics of patients with chronic hepatitis B on their mental health.And provide a reference of clinical mental health intervention for patients with chronic hepatitis B.Methods 216 cases of patients with chronic hepatitis B in our hospital from October 2010 to October 2011 were chosen as the research object.Symptom checklist-90(SCL-90)and Eysenck personality questionnaire(EPQ)were used for evaluation.The correlation of behavioral characteristics and mental health status for patients with chronic hepatitis B and the effect of behavioral characteristics of patients with chronic hepatitis B for their mental health were analyzed.Results The SCL-90 score for 216 cases of chronic hepatitis B patients showed that its total score was significantly higher than the norm,the difference was statistically significant.The results of EPQ score showed that the neurotic or emotional stability of personality scores were significantly higher than the norm,the difference was significant.The psychotic scores were significantly lower than the norm,the difference was significant.The analysis of the correlation for nine projects in the SCL-90 scale and four items in the EPQ scale showed that introversion had a significant positive correlation with compulsion,depression,anxiety,fear and paranoia.The nervous or emotion had a significant positive correlation with compulsion,interpersonal sensitivity,paranoid,psychotic.Conclusions The behavioral characteristics of chronic hepatitis B patients have a relation with the mental health.The mental health status changes according to the changes of behavioral characteristics.

Objective To evaluate the value of three-dimensional surface shaded display (SSD) and volume rendering technique(VRT) in diagnosis of scapular injury. Methods Twenty patients of scapular fractures, who were 15 males and 5 males with an average age of 34 years, were examined with SIEMENS PLUS 4 helical CT. Images were reconstructed in workstation with three-dimensional SSD and VRT, and then analyzed and compared with X-ray and 2D CT images. The regions of interesting consisted of acromion, coracoid process, glenoid cavity, supraspinous fossa, scapular spine, infraspinous fossa, lateral margin, medial margin and inferior angle of scapula. All of imagings were evaluated by two experienced radiologists with double blind method. Results 2D CT findings were clinically or operatively confirmed, and also taken as an evaluative standard to analyze the diagnostic rates of the X-ray, SSD and VRT in this study. The positive rates of diagnosis in plain X-ray and SSD were 94.44% and 97.78%, and the false negative rates was 17.65% and 7.84% respectively; the false positive rate of diagnosis of plain X-ray was 0.76%; the positive rate of diagnosis of VRT was 100%. The difference between plain X-ray, 2D CT, SSD and VRT was not statistically significant for scapular fractures, but the quality of imaging to display the fracture details of 3D CT was the best, while 3D CT might obtain the most objective view of scapular fractures. Eight cases of scapular fractures were examined again post-operatively, the reconstructed images of 3D CT displayed the structure of scapular fractures clearly. VRT could show the contour of scapula and position of the internal fixation, as well as the effect of reduction after operation and the healing status of scapular fractures. Conclusion SSD and VRT of spiral CT are effective methods in diagnosing scapular injury. The images of SSD and VRT of spiral CT may provide exact guidance to preoperative protocol and internal fixation. For complicated scapular fractures, these two techniques could be regarded as imaging techniques of choice. Furthermore, VRT provides more important information to apply the internal fixation devices and assess the result of surgical reduction.

OBJECTIVETo investigate whether the genistein can increase the radiosensitizing effect on laryngeal squamous carcinoma Hep-2 cells.METHODS Hep-2 cells were treated with genistein, radiation, and genistein plus radiation respectively. DMSO was used as the control group. EdU assay was performed to assess the short-term effect of genistein and (or) radiation on the proliferation of Hep-2 cells. Clonegenic assay was used to detect the survival rate of Hep-2 cells after treatment with radiation doses of 0, 2, 4, 6, 8 Gy and radiation combined with genistein. The data was fitted into the classic single-hit multi-target mathematical model to analyze the long-term effect on cell proliferation death of Hep-2 cells.RESULTSIt was observed that radiation combined with genistein could significantly inhibit the proliferation of Hep-2 cells. And the SER of 10μmol/L genistein was 1.412.CONCLUTIONGenistein can inhibit the proliferation of Hep-2 cells by DNA synthesis inhibition, and can be an adjunct agent of radiotherapy.
