Background and purpose: Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) can be used for magnetic resonance imaging systemic examination, especially in examing the metastatic lesions, lymph node and bone diseases, and the imaging result is similar with PET. This study aimed to evaluate the application value of magnetic resonance DWIBS and positron emission tomography with computed tomography (PET/CT) on malignant metastatic diseases. Methods: Thirty-six patients confirmed with malignant tumors accompanying metastasis by the pathology of operation or biopsy underwent both DWIBS imaging and PET/CT, chi-square test and Kappa test were used for comparing the detection results of metastasis by these 2 imaging methods. Results:Among the 36 malignant tumor patients with 238 metastatic lesions, 218 (91.6%, 218/238) lesions in DWIBS and 209 (87.8%, 209/238) lesions in PET/CT were detected, with 200 lesions detected by the two methods simultaneously, and the concordance rate was 88.7%(211/238);but there was no statistical signiifcance between this two methods (χ2=1.843, P=0.157). Kappa test showed a fair concordance rate between DWIBS and PET/CT (P=0.000).There were different significance between DWIBS and PET/CT in detecting metastatic lesions of brain and bone (P=0.005 and 0.031);But there was no signiifcant differences (P=0.309 and 1.000) in detecting metastatic lesions of lymph nodes and liver. Conclusion:DWIBS could detect metastatic lesions effectively, and there is ifne consistency with PET/CT. DWIBS is more sensitive than PET/CT in detecting metastatic lesions of brain and bone, so DWIBS could be chosed for screening metastatic lesions according to the characteristics of different primary tumors.

Objective To investigate the expression of FHIT gene in the 60Co gamma-ray irradiated human lymphocytoblast(AHH-1) cell and the bystander effect cell,and to explore the function of FHIT gene in the bystander effect of ionizing radiation.Method Preparation of bystander effect cell model:after irradiated with different dose of 60Co gamma-ray(0,2,5 Gy),the directly irradiated AHH-1 ceils were collected immediately by centfifugation and co-cultivated with non-irradiated cells in Transwell.forming the bystander effect group P1.In addition,some culture media supernatant of direcfly irradiated cells were transfefred to the non- irradiated cells culture medium,forming the group P2.Then cells were collected at 0,6,12,and 24 h after irradiation and the total RNA and protein were extracted.RT-PcR and Western blot were performed to determine the FHIT mRNA and protein level.respectively.Flow cytometry assay and cell counting were conducted to detect the alteration of cell cycle and cell proliferation,respectively at 0,24 h after irradiation.Results The mRNA level of FHIT gene among control cells,directly irradiated cells and bystander cells showed no obvious difference. while the FHIT protein level of the directly irradiated ceils and bystander cells was siguificandy down-regulated compared with the control cells(F=102.45,P<0.001).Moreover,the directly irradiated cells and bystander cells showed significant G2 phase arrest and obviously inhibited the proliferation ability.Conclusions 2 and 5 Gy of 60Co γ-ray irradiated AHH-1 cells can result in down regulation of the FHIT protein expression,which suggests that FHIT gene is involved in the process of bvstander effect induced by irradiation.

Objective To study the significance of alteration of concentration of endothelins(ET) and calcitonin gene related protein(CGRP) in bile in patients with acute choiangitis of severe type(ACST). Methods The concentration of ET and CGRP were detected by radioimmunoassay in 55 cases of ACST at openation time, and 7th, 14th day after operation. Results Compared with the control group, the concentration of ET in bile in patients with ACST was significantly higher at operation time(P<0.01~0.001). The concentration of ET in bile also showed significant difference at operation time between the 2 groups with different ACST severity(P<0.05). The concentration of ET in bile gradually reduced after operations. Compared with the control group, the concentration of CGRP in bile was signficantly lower at operation time(P<0.01). CGRP in bile gradually rose after operation. Conclusions The ET in bile has some effect on the ACST pathologic alterations. The content of ET in bile is related to the severity of ACST. The disturbance of the balance between bile ET and CGRP may contribute to the pathologic process of liver and bile duct injury in ACST.

Background and purpose:Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) can be used for MR imaging systemic examination, especially the lymph node and bone diseases can be clear, and the imaging result is similar with PET. The aim of this study was to compare the value of clinical application in the diagnosis of malignant metastatic osteopathic between DWIBS and bone scintigraphy mapping. Methods:Thirty-six specimens conifrmed with malignant tumors by the pathology of operation or biopsy underwent both DWIBS imaging and bone scintigraphy mapping, chi-square test was used for comparing the detection results of bone metastasis by this two imaging methods. Results:Thirty (165 positions in all) of 36 malignant tumor patients were conifrmed as having bone metastasis, compared that 26 patients (143 positions) with DWIBS method and 23 patients (132 positions) with bone scintigraphy mapping were detected, but there was no statistical signiifcance between this two imaging methods (χ2=1.002, P=0.506). The sensitivity, positive predictive value (PPV) and accuracy of the detection rate of bone metastasis were similar in DWIBS and bone scintigraphy, with 86.7%, 96.3%, 86.1%and 76.7%, 88.5%, 72.2%, respectively;but the speciifcity and negative predictive value (NPV) in DWIBS (83.3%and 55.6%) was higher than that of in bone scintigraphy (50.0%and 30.0%). The detection rates of different bone metastasis with DWIBS and bone scintigraphy were 86.7%(143/165) and 80.0%(132/165), and it was no signiifcant difference (χ2=2.640, P=0.104);DWIBS method was better than bone scintigraphy in the detection of osseous metastasis on pelvis and limbs long bone, and there was different signiifcant (χ2=6.783 and 7.636, P=0.023 and 0.016). Conclusion:DWIBS could detect bone metastatic lesions effectively, and there is ifne consistency with bone scintigraphy. Therefore, DWIBS is to hope to be extended and applicated clinically.
