High-performance phototheranostics with combined photothermal therapy and photoacoustic imaging have been considered promising approaches for efficient cancer diagnosis and treatment. However, developing phototheranostic materials with efficient photothermal conversion efficiency (PCE), especially over the second near-infrared window (NIR-II, 1000-1700 nm), remains challenging. Herein, we report an ultraefficient NIR-II-activated nanomedicine with phototheranostic and vaccination capability for highly efficient in vivo tumor elimination and metastasis inhibition. The NIR-II nanomedicine of a semiconducting biradical oligomer with a motor-flexible design was demonstrated with a record-breaking PCE of 87% upon NIR-II excitation. This nanomedicine inherently features extraordinary photothermal stability, good biocompatibility, and excellent photoacoustic performance, contributing to high-contrast photoacoustic imaging in living mice and high-performance photothermal elimination of tumors. Moreover, a whole-cell vaccine based on a NIR-II nanomedicine with NIR-II-activated performance was further designed to remotely activate the antitumor immunologic memory and effectively inhibit tumor occurrence and metastasis in vivo, with good biosafety. Thus, this work paves a new avenue for designing NIR-II active semiconducting biradical materials as a promising theranostics platform and further promotes the development of NIR-II nanomedicine for personalized cancer treatment.

Objective To compare the prophylactic effect of laminar closure between titanium miniplate and anchor fixation in open-door cervical laminoplasty.Methods Between January 2010 and December 2010,63 patients with cervical spondylotic myelopathy were treated by open-door laminoplasty.Of them,30 patients underwent laminoplasty by titanium miniplate fixation and 33 by anchor fixation.During follow-up,multi-detector CT was performed preoperatively,at 1 week and 6 months after surgery.At each level,the anteroposterior diameter (APD) of the spinal canal and opening angle (OA) were measured.And the spinal canal expansion rate are calculated.MRI was performed preoperatively and 1 year after surgery to evaluate the severity of cord compression.Results All incisions healed by first intention.The incidence of postoperative axial symptoms in miniplate fixation group and anchor fixation group were 33.3％ (10/30) and 39.4％ (13/33),respectively.The OA,APD,and the spinal canal expansion rate of patients in both groups improved significant postoperatively,but differing from miniplate fixation group.The OA,the APD and the spinal canal expansion rate in anchor fixation group after 6 months were reduced than one week after surgery,and the difference between the groups was statistically significant.Lamina close in two groups was not found.CT images at 6 months showed complete fusion of the hinge area by mature bone or callus in two groups,by cervical sagittal MRI assessment.The severity of spinal cord compression was improved after 1 year.Preoperative and 1 year after the surgery,the severity of spinal cord compression between the two groups showed no significant difference.The severity of spinal cord compression after 1 year in both groups were no more than three grade.Conclusion Open-door cervical laminoplasty by anchor fixation or titanium miniplate can effectively prevent the occurrence of postoperative lamina closure,which can help patients to do functional exercises early,but improvement of spinal cord compression has no significant difference between both of them.However,titanium miniplate fixation for maintenance of the expansive spinal canal is better.

[Objective] To evaluate the efficacy and short-term results of selective expansive open-door laminoplasty(ELAP).[Method] From June 2005-June 2006,a total of 102 pataents with cervical spondylotic myelopathy(CSM)were enrolled in this study.Forty-four patients underwent ELAP.Fifty-eight patients undergoing conventional C3~7 ELAP served as controls.The clinical results and radiological examinations of both groups were evaluated at 12 month after surgery.[Result]There was no significant difference in recovery rate of Japanese Orthopaedic Association(JOA)scores.The incidence of axial symptoms in the selective ELAP group was significantly lower than those in the C3~7 ELAP group(P
