Objective To evaluate the palliative effect of 89 SrCl on multiple metastatic bone-pain of malignant turnouts.Methods The palliative effect and side effect of 126 patients with metastatic bone-pain of malignant turnouts after intravenous injeotion 89SrCl were observed.Results The bone-pain vanished or released in 109 patients after therapy.The total effective rate was 86.5%.Bone scan showed that metastatic focals in 38 patients grew down and vanished.The counts of leucocyte was decreased mildly in 19 patients.The damage of liver and kidney was not observed after therapy.Conclusion The 89 SrCl has obvious effect on treating patients with metastatic bone-pain and osteolytic of carcinoma,the aide-effect is mild and it can be used repeatedly.

Cardiopulmonary resuscitation (CPR) is vital for cardio arrest victims; in this field, researches have been aiming at its mechanism, operation guidelines, new CPR machines and so on. This paper summarized the studies on the mechanical characteristics of the thorax under CPR, and on the simulation work of sternal-displacement relationship in CPR manikins. The data from modeling work showed that the thorax's sternal-displacement relationship could be graphically represented by a hysteresis curve. As the actual CPR manikins' mechanical structures of the thorax are too simplified, it is necessary to do the work of improvement.

Objective:To investigate the value of the three-dimensional CT reconstruction by computer photo process system for laryngeal carcinoma and control study with pathologic feature. Methods: Fifty patients with laryngeal carcinoma were scanned by helical CT which photos were three-dimensionally reconstructed with a photo processing system,and the images were compared with pathologic feature.Results:Clear three-dimensional photo of the laryngeal was obtained through the reconstruction of the helical CT.The images could be circular fully around the axis of X,Y and Z in order to find the best view of the diagnosis.Ninety-six percentage of the TNM stage of patients according to the images of three-dimensional reconstruction were consistent with the TNM stage after operation.The safe edge was obtained in 98% of the surgery for patients.Good correlations were showed in the images of the three-dimensional reconstruction of the larynx and pathologic specimens.Conclusion:Good consistent of the three-dimensional images of the larynx with pathologic specimen were useful for diagnosis,operation design and education.
