OBJECTIVESTo investigate the surgical results of one-stage total en bloc spondylectomy (TES) and reconstruction via a single posterior approach for thoracic symptomatic vertebral hemangioma associated with spinal cord dysfunction and evaluate its curative effect.

METHODSA total of 9 patients treated with one-stage TES (7 cases) and total vertebrectomy (2 cases) by posterior approach from March 2006 to January 2010 were retrospectively reviewed. The cases included 2 males and 7 females with a median age of 33.6 years (range 14 to 77 years), and with 1 case of Grade A, 3 cases of Grade B, 3 cases of Grade C, 2 cases of Grade D according to Frankel grade system. All patients suffered from moderate to severe pain and neurological deficit with an average symptom duration of 14.4 months (range 3 - 24 months) MRI revealed severe spinal cord compression. The spinal reconstruction was obtained by titanium mesh filled with autograft and posterior internal fixation with rod-screw system.

RESULTSThe operation time was 210 minutes on average (180 - 270 minutes) and the average blood loss was 1800 ml (1000 - 5000 ml). The follow-up period lasted from 18 months to 5 years. All cases with preoperative pain relieved after operation. The visual analogue scale pain scores decreased to 1.1 from 8.3 at 3 months after surgery. No disruption of dural mater, cerebrospinal fluid leakage, iatrogenic spinal cord injury and major vessel damage occurred. Up to now, there was no local recurrence in all cases. Significant neurological function improvement was achieved in all patients with one to three grades in Frankel grade system. Fusion of the autograft was well achieved and no internal fixation failure in all patients.

CONCLUSIONSOne-stage TES and spine reconstruction by a single posterior approach is feasible, safe and effective to this disease. It is favourable in decreasing the hemangioma recurrence and improvement of the neurological function.

OBJECTIVE: To analyze the clinical efficacy and technical characteristics of percutaneous endoscopic lumbar discecomy in the treatment of upper lumbar disc herniation. METHODS: The clinical data of 9 patients with upper lumbar disc herniation underwent percutaneous endoscopic lumbar discecomy from January 2012 to October 2019 were retrospectively analyzed. There were 6 males and 3 females, aged 26 to 79 years, including 2 patients with L disc herniation and 7 patients with L2, 3 disc herniation. Visual analogue scale (VAS) and Japanese Orthopeadic Association (JOA) score were recorded before and after surgery. The clinical efficacy was evaluated according to the modified Macnab standard. RESULTS: All 9 patients were followedup, and the follow-up time was 1 day and 3 months after surgery. The operation time was 1.5 to 2.9 h and postoperative hospital stay was 5 to 8 d. No cerebrospinal fluid leakage or spinal cord injury occurred during the operation. Preoperative and postoperative at 1 day, 3 months, the VAS scores of 9 patients were 7 to 8 scores, 1 to 3 scores, 0 to 1 case, JOA scores were 5 to 7 scores, 15 to 24 scores, 21 to 26 scores, respectively. The improvement rate of JOA was 36.4% to 78.3% on the first day and 65.2% to 87.5% three months after operation. According to modified Macnab standard to evaluate effect, 4 cases got excellent results, 4 good, 1 fair. CONCLUSION Percutaneous endoscopic lumbar discecomy has reliable therapeutic effect for upper lumbar disc herniation in line with the indications, and it has the characteristics of small trauma and short operation time, so it is more suitable for middle aged and elderly patients with poor physique and can replace part of transforaminal lumbar interbody fusion.

Objective: To analyze the association between exposure patterns of adverse childhood experiences (ACEs) and anxiety symptom trajectories in medical college students. Methods: A survey was conducted on first-year students from Anhui Medical College and Anqing Medical College, using the Childhood Abuse Questionnaire, Family Disability Questionnaire, Childhood Adverse Social Experience Item, and Anxiety Self Rating Scale. The baseline survey was conducted from November to December 2019, and two follow-up visits were conducted once every six months until November to December 2020. The latent class analysis (LCA) was used to analyze the exposure patterns of ACEs. The latent class growth analysis (LCGA) was used to analyze the development trajectory of anxiety symptoms. The multiple logistic regression model was used to analyze the correlation between different exposure patterns of ACEs and the trajectory of anxiety symptom trajectories. Results: A total of 3 662 college students aged (19.2±1.0) were surveyed. The LCA showed that the exposure patterns of ACEs could be divided into the "high ACEs" group (13.4%), "high neglect/emotional abuse" group (25.7%), "high family dysfunction" group (6.9%), "high neglect" group (27.1%), and "low ACEs" group (26.3%). The LCGA divided anxiety trajectories into four groups: "high anxiety decline" (7.1%),"anxiety increase "(4.1%), "moderate anxiety"(52.9%), and "low anxiety"(35.9%). Using the low ACEs group as a reference group, compared with the low anxiety trajectory, the high ACEs group, high neglect/emotional abuse group, high family dysfunction group, high neglect group, and medium to high-level anxiety trajectory were all associated with an increased risk (P<0.05). Conclusion: There is heterogeneity in ACEs exposure patterns among medical college students, and ACEs exposure patterns are important influencing factors for anxiety symptom trajectories.
