Objective To investigate the level and relationships of posttraumatic growth (PTG) and psychological distress among patients with prostate cancer. Method Totally 116 patients with prostate cancer involved in the investigation by a self-designed demographic questionnaire, posttraumatic growth inventory (PTGI) and distress thermometer (DT). Results The total score of PTGI was (53.12 ± 13.51), at a low level, and the score of DT was (4.32 ± 2.59), at a medium level. The score of DT was negatively correlated to the scores of PTG and its dimensions (all P<0.05). Conclusions Patients with prostate cancer show a low level of PTG and a medium level of psychological distress and they are negatively related . Therefore , nurses should take measures to reduce the patients psychological distress and then improve their PTG level.

ObjectiveTo investigate the postoperative 3D MRI appearances and their evolvement patterns of ACL grafts and bone tunnels at follow-up.Methods There were 26 double bundles ACL reconstructions and 16 single bundle ACL reconstructions,and a total of 56 follow-up 3D MR Imaging.MR images were reconstructed with MPR technique to evaluate grafts,bone tunnels,fixers and associated.complications.Proportions of grafts with hypointensity or hyperintensity and occurrence rates of marrow edema around bone tunnels were calculated respectively among groups of different periods after operation.ResultsThere were 24 grafts of hypointensity and 32 grafts of hyperintensity.Grafts of 2 cases were suspended with cross pins within femoral tunnels,graft of 1 case was suspended with an endobutton within the femoral tunnel,and grafts of other sites were fixed with interference screws.In the three periods as 3 months,6 to 9 months and over 12 months after cruciate ligament reconstruction,proportions of hypointensive grafts were 20/25,0/14 and 4/10 respectively,while proportions of hyperintensive grafts were 5/25,14/14 and 6/10 respectively,occurrence proportions of marrow edema around bone tunnels were 54/54,10/32 and 4/26 respectively.There was 1 tear graft,4 tibial tunnels placed anteriorly with ACL graft impingement on the intercondylar roof,3 femoral tunnels placed anteriorly,and 2 bone tunnels with mismatching interference screws.Conclusion3D MRI can accurately demonstrate the state of ACL grafts,bone tunnels,fixers and associated complications.Intensity of grafts presented a rise and reduce pattern after operation.

Objective To investigate the diagnostic value of strain ratio for differentiation breast benign and malignant solid lesions. Methods Two hundred and sixty-nine patients with 377 lesions (278 benign, 99 malignant) were included in the study. Ultrasonography found the lesions, then ultrasonic elastography got the strain images. By the strain ratio measure method equipped with the ultrasonic machine, strain ratio of the lesion was calculated. Compared with the pathologic diagnosis, the cut-off point of strain ratio was determined with receiver operating characteristic curve. Results There was significant difference between the strain ratio of benign and malignant lesions( P <0. 05). The cut off point of strain ratio was determined as 3. 08, Youden's index was 0. 88,sensitivity was 97. 38% ,and specificity was 91. 33%. Conclusions Strain ratio could be used to differentiate benign and malignant lesions in breast and would be a new diagnostic standard in future.

Objective: To investigate application effect of collaborative care model on self?cre ablilioy in patients with craniocere?bral trauma in recovery period. Methods: A total of 96 patients with craniocerebral trauma in recovery period were randomly divided into experimental group and control group ( n=48) . Control group received the routine nursing methods. The experimental group re?ceived collaborative care model on the basis of routine nursing methods. Self care ability scale ( ESCA) was used to evaluate self?care ability in two groups before and after the intervention. Results: There was no statistical significance in self?care ability before inter?vention in two groups ( P>0?05) . Self?care skills, personal responsibility, self concept and health knowledge levels in the experi?mental group after intervention were significantly higher than those in the control group ( P<0?01) . Conclusion: Collaborative care model used in patients with craniocerebral trauma in recovery period can solve a variety of health problems, improve the training effect, and improve the level of self?care ability.
