Objective:To explore the effects of body mass index (BMI) and gender on primary lung cancer 18F-FDG uptake param-eters, standardized uptake value (SUV), and standard uptake value of lean body mass (SUL). Methods:Data of 50 patients with prima-ry lung cancer confirmed by 18F-FDG positron emission tomography (PET)/computed tomography (CT) were retrospectively analyzed. AW4.6 workstation was employed to measure the SUVmean and SUVmax. Meanwhile, PETVCAR (PET Volume Computed Assisted Reading, GE Healthcare) software was used to automatically measure the SULmean, SULmax, and SULpeak. The SUVmean, SUV-max, SULmean, and SULmax of the liver (central region of the right lobe) were also measured automatically by PETVCAR. Afterward, T/N ratios (lesion SUVmax/liver SUVmean, lesion SULmax/liver SULmean, and lesion SULpeak/liver SULmean) of the lung cancer lesions were calculated. Correlations of the 18F-FDG metabolic parameters with BMI and gender of the patients were analyzed. Results:Liver SUVmean and SUVmax demonstrated significant positive correlations with BMI in all the patients (γ=0.38 and 0.36, P<0.05), and the SUVmean and SUVmax were positively correlated with BMI in male and female groups (γ=0.47 and 0.44, P<0.05), respective-ly. By contrast, no correlation existed between the liver SULmean and SULmax and BMI (P>0.05). No significant correlation was not-ed between the SUVmean, SUVmax, SULmean, SULmax, and SULpeak of the lung cancer lesions and BMI (P>0.05). The correlation trend is the same as that in different gender groups. Only the SUVmax T/N ratio of the lung cancer lesions showed a significant nega-tive correlation with BMI (γ=?0.29, P<0.05). The T/N ratios did not correlate with BMI in the different gender groups (P>0.05). Con-clusion:Patient BMI and gender mainly affect SUV values, particularly SUVmax, by contrast, patient BMI and gender did not signifi-cantly influence SUL and T/N ratio (SUL). Hence, SUL can be more suitable to quantitatively analyze and assess treatment response ob-jectively. This result will be helpful to the clinical application and promotion of PERCIST, which evaluates treatment response mainly by SUL.

Objective: To evaluate and compare the safety and efficiency of the combined therapy of 89Sr plus zoledronic acid and those of 89Sr-chloride alone, in patients with painful bone metastases. Methods: A total of 87 patients with osseous metastasis were ran-domly divided into treatment groups of 89Sr-chloride alone (group A, 53 patients) and 89Sr plus zoledronic acid (group B, 34 patients). A total of 17 patients in group B received zoledronic acid 2-14 days after 89Sr therapy, and 13 other patients in the group received 89Sr 4-7 days after zoledronic-acid therapy. Pain response and KPS score were evaluated after the different treatments. Results: No obvious bone marrow suppression and liver damage were found in all cases. All patients who received both 89Sr-chloride and 89Sr plus zoledronic acid showed reduced bone pain and total discomfort, as well as improved KPS score, but the response was more pronounced in group B (P=0.047; P=0.036). No statistical differences in pain score and KPS scores were observed between the groups treated with zoledronic acid first and 89Sr therapy first (P=1.000; P=0.667). Comparison of bone pain relief and changes in the KPS score of different primary tumors after treatment with 89Sr-chloride or 89Sr plus zoledronic acid showed no statistical significance. Conclusion: Compared with 89Sr-chloride, treatment with 89Sr plus zoledronic acid was more effective in patients with painful bone metastases. The safety of these two treatments are similar.

BACKGROUND: Posttraumatic stress disorder(PTSD) arises as a delayed and /or protracted response to a stressful event or situation of an exceptionally threatening or catastrophic nature. There have been reports about natural disasters causing PTSD, but there have been few reports about PTSDcaused by technological disasters. Our study investigated the mental status of those survivors after a serious explosion.OBJECTIVE: To investigate the characteristics and the factors of impact of PTSD caused by technological disasters.DESIGN: A case controlled study of the survivors of a momentous explosion.SETTING: A provincial mental health center.PARTICIPANTS: A serious explosion happened in Urumqi on September 8, 2000. Twenty-eight survivors(as the study group) who were still hospitalized for treatment 3 -5 months after the accident were involved in this study. And in the control group were 30 normal persons whose general demographic data were the same as those patients.METHODS: A psychiatrist told the subjects the following: The objective and meaning of the test, and explained the self-making questionnaire about their general condition, symptom checklist (SCL-90), self-rating anxiety scale (SAS), self-rating depression scale(SDS), cornell medical index(CMI), the questionnaire on dealing styles, the questionnaire on social support, and others-evaluating scale, incident effect scale(IES); a list of stress reaction symptoms.MAIN OUTCOME MEASURES:Main resulta:①Clinical feature of PTSD caused by the technological disaster.②the related factors to PTSD in the technologal disaster.Secondary results: Comparison of the results between the two groups in IES, CMI, SDS and SAS.RESULTS: A total of 22(79% ) survivors met the criteria as PTSD. There were significant differences in all the assessments(IES, CMI, SDS, SAS,SCL-90) between the study group and the control group (t =3.62-8.17, P < 0.01 ) . The diagnosis of PTSD was positively correlated with the level of traumatic exposure( r = 0. 420, P < 0. 05), and negatively correlated with the degree of satisfaction with the post-event solutions( r = 0. 420, P< 0.05), positively correlated with IES scoring and the level of heart pain ( r = 0. 389 - 0. 665, P < 0. 01 ) . The total scores of IES were positively correlated with the level of exposure ( r = 0. 478, P < 0.05 ).CONCLUSION: The incidence of PTSD after explosion was high, and its occurrence was related with the degree of exposure in the event and that of the satisfaction with the post-event solutions.

Objective To study the feasibility of noninvasive detection of unstable plaques with ~(18)F-Fluorodeoxyglu-cose (~(18)F-FDG) PET/CT imaging. Methods Atherosclerotic plaques were induced in male New Zealand white rabbits. Animals were injected with FDG labeled with ~(18)F, then examined with PET/CT. Aorta was explanted for photography with digital camera, and ~(18)F-FDG uptake analysis. Thirty unstable plaques and 30 stable plaques were choosed so as to compare the quantitativly ~(18)F-FDG uptake. The number of macrophages and smooth muscle cells was detected by immunohistochemical technique. Results Experimental group showed inconsistent uptake of ~(18)F-FDG in the abdominal aorta. The results were confirmed in the ex vivo digital photo of the explanted aorta. The target to non target ratio (T/NT) and macrophages of unstable plaques were higher than stable plaques (P<0.01) , but smooth muscle cells obviously reduced (P <0. 01). Correlation analysis showed that there was a positive correlation between T/NT and macrophage content (r=0. 815,P<0. 01), and a negative correlation between T/NT and SMC content(r=-0. 684,P <0. 01). Conclusion ~(18)F-FDG PET/CT can constitute an attractive imaging method for the noninvasive detection of experimental unstable plaques.
