Benign and malignant compression fracture of vertebrae are common diseases in clinic. Because their therapies are different,it is important to identify them. At present, MRI is the main means in discriminating benign and malignant compression fracture of vertebrae. Sometimes the change of MRI signal in them is overlap, therefore, it is difficult to diagnose accurately. In the recent years, with the appearance of MRI new technology, people have already applied it to work out the difficulty.

The article focuses on diagnostic criteria and diagnostic accuracy of the various imaging methods by lymph node metastasis in esophageal carcinoma at present, and compares accuracy of the various imaging methods. In general, the diagnostic accuracy of CT is lower, the diagnostic accuracy of uhrasmall superparamagnetic iron oxide-enhanced MR imaging is higher. Each imaging method has the lower accuracy for the diagnosis of smaller lymph node metastasis. Diagnostic accuracy of endoscopic ultrasonography is higher in the diagnosis of mediastinal lymph node metastasis. Sensitivity of PET/CT is higher for the diagnosis of distant lymph node metastasis.

Objective To evaluate the value of high resolution MR imaging (MRI) with diffusion weighted imaging (DWI) in the preoperative diagnosis of rectal cancer. Methods 55 patients with rectal cancer may underwent high resolution MRI examinations before surgical operation, and with DWI (b=600, 1000 s/mm2). The apparent diffusion coefficient (ADC) of the tumors were measured. The image findings were compared with pathology. Select 15 patients without rectal lesion, ADC value of the tumors and normal rectal wall were measured. Results High resolution MRI diagnosis rectal cancer sensitivity, specific degree and coincidence rate were 95.7% (45/47), 50.0% (4/8), 89.1% (49/55), high resolution MRI with DWI diagnosis colorectal cancer sensitivity, specific degree and coincidence rate were 100.0 % (47/47), 75.0 % (6/8), 96.4 % (53/55). The high resolution MRI tumor T-staging agreed with the histological stage that was 88.9% (40/45), the diagnosis of T2 stage was 87.5 % (14/16), the diagnosis of T3 stage was 89.6 % (26/29). The same b-valued under the ADC values of rectal cancer tumors and the normal rectal were different (P ＜0.05). No correlation can be pointed out between ADC and pathological classification of each tumor.Conclusion High resolution MRI with DWI for the rectal cancer preoperative diagnosis and T-staging has higher diagnostic accuracy, DWI can serve as an important supplement sequence of colorectal cancer diagnosis.

Objective To analyze the difference of irradiation dose and volume of organs at risk (OAR) particularly in small intestine between supine position and prone position on intensity-roodulated radiotherapy(IMRT) for cervical cancer. Methods 11 patients with Ⅱ_B-Ⅲ_B cervical cancer were scanned with supine position and prone position by CT.The CT images were transported to TPS,then target volumes were delineated and the IMRT plans were designed respectively.The prescribed dose was 95%PTV receiving 45 Gy in 23 fractions of 2 Gy.The exposure volumes of the OAR at different position and different dose levels in the dose volume histograms (DVH) were compared and analyzed.Results When tlle dose di8tributions met to the clinic request,the exposure volumes of small intestine at prone position were redueed than that at supine position in dose range 46-30 Gy(P<0.05),but this phenomenon Was not distinct in low dose range(< 20 Gy)(P>0.05).The exposure volumes of bladder, rectum, femur head and spine cord were no obviously differences at dissimilar position. Conclusion IMRT of cervical cancer should adopt prone position.because their small intestine will be protected better.

This study examined the association of problem behavior with neurotransmitter deficiency in adolescents, which would provide new insights into behavioral problems. A total of 1259 students of the seventh grade from 4 middle schools in Wuhan city located in the central China were recruited. With the approval of school and parents, they were invited to complete the Youth Self-Report (YSR) questionnaire and Symptom Scale of Neurotransmitter Deficiency (SSND) questionnaire. Pearson's bivariate correlation analysis showed that the correlation coefficients between each subscale of YSR and SSND ranged from 0.24 to 0.61 with all P<0.01. Canonical correlation analysis indicated that anxiety/depression was interrelated with insufficiency of GABA and 5-HT; aggressive behavior was associated with inadequate GABA; famine of DA influenced the attention problems. It was concluded that neurotransmitter deficiency may cause a series of behavioral and mental problems.

Objective To investigate the influence of preoperative arterial chemoembolization on the expression of Survivin,and study the clinical significance in bladder cancer.Methods The tissue before and after chemoembolization of 50 patients with bladder cancer were selected,the Survivin expression was examined by immunohistochemical method.The Survivin expression was compared between before and after chemoembolization in bladder cancer tissue,and the relation of its expression to the pathological grade and clinical stage was evaluated clinically.Results The positive rate of Survivin expression before chemoembolization raised with the rising of the pathological grade and clinical stage,there was statistical difference (P ＜ 0.05).The positive rate of Survivin expression before and after chemoembolization was 72％ (36/50) and 22％ (11/50),there was statistical difference (P ＜0.01).The positive rate of Survivin expression in high grade pathological grade and T2-T4 clinical stage after chemoembolization was significantly lower than that before chemoembolization,there was statistical difference (P ＜0.01).The survival rate 3 years after chemoembolization in Survivin negative expression patients was higher than that in Survivin positive expression patients [94.87％(37/39) vs.7/11],but there was no statistical difference (P ＞ 0.05).The Survivin positive expression in recurrence patients was significantly higher than that in non-recurrence patients [5/8 vs.5.56％ (2/36)],there was statistical difference (P ＜ 0.01).Conclusions Preoperative arterial chemoembolization can reduce the expression of Survivin,adjust malignancy of bladder cancer,could downgrade and downstage the tumor,reduce recurrence rate.The expression of Survivin can serve as predictive factor for prognosis of bladder cancer.

Objective To study the influence of transeatheter bladder arterial chemoembolization on neovascularization and vascular endothelial growth factor (VEGF) expression in bladder cancer treatment. Methods Thirty bladder cancer patients (Tis =1, Ta =2, T1 =6, T2 =11, T3 =9, T4 = 1; G1 = 9, G2=13, G3 = 8) were treated with transcatheter arterial chemotherapy with Mitomycin (20 mg) or Hydroxycamptothecin (10 nag) adding cisplatin (60 rag) and embolization with gelatine sponge particle gelform 1 week before surgery. Before and after the chemoembolization, the expression of VEGF and microvessel density (MVD) count in cancer tissue were examined by SP immunohistochemical staining. Tumor samples after chemoembolization were taken and sent for pathological examination. The over all survival rates were recorded and analyzed as well. Results Before and after the chemoembolization, positive rates of VEGF expression in bladder cancer tissue were 73. 3% and 43.3%, respectively and MVD were 69.8±3.4 and 56. 4±3.3, respectively. There were significant differences between the parameters before and after the treatment (P<0.05). After the intervention, tumor diameter decreased from 2.2±0.9 cm to 1.6±0. 9 cm (P<0.05) and tumor tissues were in severe necrosis and degeneration. During the follow-up of 24. 6 months (ranging from 12 to 36 months),there were 5 recurrent cases (G1 T1 =1, G2 T1=1, G2T3=1, G3T3 = 1, G3 T4 =1, primary transitional cell carcinoma= 4, admixture carcinoma= 1). In the recurrent group, VEGF expression were positive in 5 cases (100% strong positive) and 4 cases (80%, 3 positive, 1 strong positive) (P>0. 05) before and after the chemoembolization. However, it had significant difference in strong positive expression (P<0.05); MVD were 87.4±3.0 and 72.4±4.1 (P<0.05) before and after the treatment. The MVD in no recurrent group was 53.2±3. 5 after chemoembolization, and it had statistical significance comparing with the recurrent group (P<0. 05). Conclusions The chemoembolization can decrease the expression of tumor VEGF and MVD. Thus, it can adjust bladder cancer malignancy, downgrade and downstage the tumors and decrease the risk of postoperative metastasis. For the long-term, this treatment will improve the survival rate and reduce recurrence rate.

Objective To investigate the influence of preoperative arterial chemoembolization on expression of Ki-67,and clinical significance in bladder cancer. Methods Before and after chemoembolizafion of therapy,the expression of Ki-67 in 30 patients of bladder cancer tissue were examined by immunohistochemical staining.The rehtion of its expression to the pathological grade and clinical stage was evaluated clinically.Results Positive rate of Ki-67 expression in the bladder cancer tissue was 70.00% and 26.67% respectively.There was significant difference between the before and after therapy (P＜0.01). Follow-up for mean 24.6 months recurrence rate in 30 cases was 16.67%.The expression of Ki-67 correhted to the pathological grade, clinical stage and patient recurrence rates of bladder cancer.Conclusions Preoperative arterial chemeembelization can reduce the expression of Ki-67,adjust malignancy of bladder cancer,could downgrade and downstage the tumors,and cut down the postoperative metastasis,improve survival rate and reduce recurrence rate.Both of the Ki-67 labeling index are predictive factor for recurrence of superficial bladder cancer.
