OBJECTIVE: To investigate the characteristics of forensic clinical identification on common peroneal nerve injury in traffic accident. METHODS: Eight cases of common peroneal nerve injury in traffic accidents were analyzed, including general condition of the wounded, the way of injury, the imaging results, the EMG results, and the degree of injury, etc. RESULTS: In 8 cases, 2 cases of complete common peroneal nerve injury were determined to grade 9 (disability degree) and 6 cases of partial common peroneal nerve injury were determined to grade 10 (disability degree). CONCLUSION By comparison, the disability degree of complete common peroneal nerve injury is higher than that of partial common peroneal nerve injury. The forensic clinical identification of common peroneal nerve should be made with synthetical consideration of medical history, symptoms, and auxiliary examinations.

Objective: To evaluate heterogeneity and clonal evolution in pediatric ETV6-RUNX1⁺ acute lymphoblastic leukemia (ALL) in China. Methods: Totally 48 children (<14 years) with newly diagnosed ETV6-RUNX1⁺ ALL in Institute of Hematology and Blood Disease Hospital, CAMS and PUMC, from February 2006 to June 2011 were included. The copy number variations were analyzed by quantitative multigene fluorescence in situ hybridization (QM-FISH) in 48 patients. Non-normal distribution of measurement data were shown with Median (range) , count data were shown with percent (%) . Overall survival and event-free survival were estimated by the Kaplan-Meier method and compared with the log-rank test. Results: Forty-eight patients were tested by QM-FISH. Of 48 patients, 70.8% harbored one clone, 18.8% two subclones, and 10.4% three or more subclones. The clone heterogeneity was detected by two different models: the linear succession model and the branching evolution model. ETV6-RUNX1⁺ ALL relapse evolved from an ancestral clone or a new clone. The patients relapsed from a new clone got the worse outcome. Conclusion The clone evolution was detected in pediatric ETV6-RUNX1⁺ ALL in China. QM-FISH might be helpful to evaluate the outcome of relapsed patients. A new clone was associated with a poorer outcome.

Radical prostatectomy (RP) is the main therapeutic method for early localized prostate cancer.With the advancement of technology，robot-assisted radical prostatectomy (RARP) is widely applied，which can enable better achievement of the “five wins”, including long-term tumor control，recovery of urinary control，negative surgical margins，preservation of erectile function，and reduced postoperative complications，thereby improving the treatment efficacy.This paper reviews the various surgical approaches (transabdominal，transperitoneal，transvesical，transperineal，single-hole)，current status of optional surgical equipment (da Vinci surgical robot，domestic robot)，and advantages and limitations of RARP，so as to provide reference for clinicians in choosing the optimal surgical method for prostate cancer.
