RESUMO
BACKGROUND: Acute central cord syndrome (ACCS) without fractures or dislocations is the most common form of incomplete spinal cord injury. OBJECTIVE: To evaluate the effectiveness of different surgical methods in the treatment of acute central cord syndrome without fractures or dislocations of the cervical spine. METHODS: A total of 164 patients with ACCS without fracture or dislocation of the cervical spine treated in our hospital from May 2012 to October 2019 were recruited and assigned to study group A and study group B according to different treatment modalities, with 82 cases in each group. Study group A underwent anterior cervical discectomy and fusion, and study group B was treated with posterior cervical laminectomy. The American Spinal Injury Association (ASIA) classification and motor scores of all cases at admission and at discharge were recorded, and the treatment outcomes of the two groups were compared. RESULTS: No significant differences were found in the ASIA classification and ASIA motor scores between the two groups at admission (P> 0.05). One year after surgery, the ASIA motor scores and sensory scores were not statistically significant between the two groups (P> 0.05) but showed significant improvement compared to the preoperative scores (P< 0.05). CONCLUSION: Both anterior cervical discectomy and fusion and posterior cervical laminectomy can improve the ASIA classification, ASIA motor scores, and sensory scores of ACCS patients without fractures or dislocations of the cervical spine. Therefore, surgical methods should be adopted based on the patients' conditions.

OBJECTIVE: To investigate the changes in the heart rates and the clinical effectiveness of aminophylline injections in acute cervical spinal cord injury (ACSCI) patients with bradycardia. METHODS: This retrospective study was conducted by studying the clinical data of 100 ACSCI patients also suffering from bradycardia admitted to our hospital from June 2019 to June 2020. The patients were randomly placed into a control group (n=50) that was administered atropine therapy and a test group (n=50) that was administered aminophylline injections. The changes in the patients' heart rates and the clinical effectiveness were analyzed. RESULTS: After the treatment, the test group had a significantly higher average heart rate, shorter heart rate recovery times, and a lower bradycardia recurrence rate than the control group (all P<0.05). The systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels in the test group were significantly higher than they were in the control group (all P<0.05). Remarkably higher clinical effectiveness and satisfaction rates and a significantly lower incidence of adverse reactions were observed in the test group compared to the control group (all P<0.05). In addition, the Japanese Orthopaedic Association (JOA) cervical spine scores were similar in the two groups (P>0.05). CONCLUSION: For ACSCI patients also suffering from bradycardia, aminophylline injections ameliorate the clinical heart rate and have a good clinical effectiveness with few adverse reactions, so the treatment merits clinical promotion and application.
RESUMO
BACKGROUND: Excessively inflammatory response is one of mechanisms that underlie the acute kidney injury (AKI) induced by severe hemorrhagic shock, which could be ameliorated by post-hemorrhagic shock mesenteric lymph (PHSML) blockage. Recent studies demonstrate that high mobility group box 1 (HMGB1) and the receptor for advanced glycation end products (RAGE) are critical mediators of local inflammations. The present study was sought to investigate whether the PHSML drainage inhibits the HMGB1 and RAGE in mouse kidney to ameliorate the renal inflammatory responses. METHODS: A mouse hemorrhagic shock model (40 ± 2 mmHg for 90 min, fluid resuscitation for 30 min) was employed, and the PHMSL drainage was performed at the end of the resuscitation. After 3 h of resuscitation, the expressions of mRNA and protein for the renal HMGB1 and RAGE and the levels of interleukin (IL)-1ß and IL-18 were assessed by the real-time reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay, respectively. RESULTS: Hemorrhagic shock elicited significant increases in the mRNA expressions of HMGB1 and RAGE and in the protein expressions of HMGB1, RAGE, IL-1ß and IL-18 in kidney. The PHSML drainage abolished these potentiating effects. CONCLUSION: The present study demonstrates that PHSML blockade reduces the increased HMGB1 and RAGE and pro-inflammatory factors following hemorrhagic shock, suggesting that the PHSML elicits the inflammatory responses via enhancing the HMGB1 and RAGE production in the kidney.

OBJECTIVE: To compare the effectiveness between the method of simple posterior debridement combined with bone grafting and fusion and internal fixation and the method of one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in the treatment of thoracolumbar brucella spondylitis so as to provide the reference for the clinical treatment. METHODS: A retrospective analysis was made on the clinical data of 148 cases of thoracolumbar brucella spondylitis between January 2002 and January 2012. Simple posterior debridement combined with bone grafting and fusion and internal fixation was used in 78 cases (group A), and one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in 70 cases (group B). There was no significant difference in gender, age, disease duration, involved vertebral segments, erythrocyte sedimentation rate (ESR), visual analogue scale (VAS) score, neural function grade of America Spinal Injury Association (ASIA), and kyphosis Cobb angle before operation between 2 groups (P > 0.05). The peri operation period indexes (hospitalization time, operation time, and intraoperative blood loss) and the clinical effectiveness indexes (VAS score, ASIA grade, Cobb angle, and ESR) were compared; the bone fusion and the internal fixation were observed. RESULTS: Incision infection and paravertebral and/or psoas abscess occurred in 2 and 3 cases of group A respectively. All incisions healed by first intention and 2 cases had pneumothorax in group B. The operation time and the hospitalization time of group A were significantly shorter than those of group B (P < 0.05), and the intraoperative blood loss of group A was significantly lower than that of group B (P < 0.05). All of the cases in 2 groups were followed up 14- 38 months, 25 months on average. The VAS, ESR, and Cobb angle were significantly decreased at each time point after operation when compared with preoperative ones in 2 groups (P < 0.05), but no significant difference was found between 2 groups (P > 0.05). The neurological function was significantly improved at 3 months after operation; there were 1 case of ASIA grade C, 14 cases of grade D, and 63 cases of grade E in group A, and there were 1 case of grade C, 11 cases of grade D, and 58 cases of grade E in group B; and difference was not significant (Z = 0.168, P = 0.682). The grafting bone fusion was observed in both groups. The fusion time was (8.7 ± 0.3) months in group A and (8.6 ± 0.4) months in group B, showing no significant difference (t = 0.591, P = 0.601) was found. At last follow-up, no loosening or fracture of internal fixation was found. CONCLUSION: Based on regular medicine therapy, the effectiveness of the two methods is satisfactory in the treatment of thoracolumbar brucella spondylitis as long as the operation indications should be controlled strictly.
