高压氧暴露对急性脑梗死患者血清S-100B蛋白含量的影响

目的 探讨高压氧(HBO)暴露对急性脑梗死患者血清S-100B蛋白含量的影响,并评价HBO的治疗作用.方法 应用颅脑MRI/MRA扫描120例急性脑梗死患者,计算脑梗死体积.按照治疗方法分成HBO组(n=56)与对照组(n=64),并采用ELISA法检测2组患者于入院后24、48、72、96h血清S-100B蛋白含量的变化.结果 急性脑梗死患者血清S-1O0B蛋白含量在入院72 h后达到顶峰,S-100B蛋白含量与脑梗死体积呈正相关(P＜0.05),HBO组入院后72 h时血清S-100B蛋白含量[小梗死:(0.71±0.25) μg/L,中梗死:(1.22±0.37) μg/L]较对照组相同时点[小梗死:(1.26±0.36) μg/L,中梗死:(2.02 ±0.72)μg/L]明显下降,差异有统计学意义(P＜0.01或P＜0.05).结论 相同时点中S-100B蛋白含量与急性脑梗死体积密切相关,可能对进展性脑卒中有预测作用;临床早期HBO治疗可以降低S-100B蛋白含量,对提高急性脑梗死患者疗效有一定的作用.

亚低温对急性重型颅脑损伤患者血清S-100 B蛋白的影响

Objective To dynamically observe the effect of mild hypothermia on concentration of plasma S-100B protein in patients with acute severe brain injuries so as to further explore its role in treat-ment of acute severe brain injury. Methods A total of 120 patients with acute severe brain injuries were randomly divided into mild hypothermia group and general group. The patients in mild hypothermia group were treated with mild hypothermia besides conventional therapy, with maintenance of rectal tem-perature at 33℃-35℃ for 3-5 days. Serial concentration of S-IOOB protein in serum was measured in all patients from 6 hours to 6 days after hospitalization. GOS evaluation was done three months after treat-ment. Results The concentration of S-100B protein in serum of mild hypothermia group and general group was significantly higher than of normal group (P <0.05), with significant lower level in mild hypo-thermia group than general group(P <0.05). Mild hypothermia could improve prognosis of patients with acute severe brain injury. Conclusions Early use of mild hypothermia can decrease concentration of S-100B protein in serum, protect neurofunction and improve prognosis, as may be related to its function in alleviating damnification brain cell inflammation reaction mediated by S-100B protein.
