机械性创伤患者血清肿瘤特异性生长因子的变化及其临床意义

Changes serum level of tumor specific growth factor and their clinical significance in mechanical trauma patients]

OBJECTIVE: To investigate the post-traumatic changes in the serum level of tumor specific growth factor (TSGF) and their relationship with Injury Severity Score and to inquire into the possible mechanism and clinical significance. METHODS: Fifty patients with mechanical trauma were eligible and included. According to the standard of Injury Severity Score (ISS), the patients were divided into there groups: mild degree group, (ISS < or = 16, n = 31) severe degree group (16 < ISS < 25, n = 13) extreme severe degree group (ISS > or = 25, n = 6). The blood samples of all patients were obtained within 24 hours, and those of 25 dynamically observed patients were obtained on days 3, 5, 7, 9 and 12. RESULTS: The serum level of TSGF was significantly higher in patients with trauma in different groups (P < 0.05). The dynamical observation showed that the index demonstrated curve changes with increase in early stage and decrease later. the climax of TSGF appeared on 7 day in all 3 groups. The TSGF serum levels in extremely severe degree and severe degree groups > mild degree group on days 5, 7, 9 and 12 day (P < 0.05). CONCLUSION: TSGF has relationship with the inflammatory response and recovery of trauma.
