目的

探讨丁苯酞对一氧化碳中毒迟发性脑病(DEACMP)的疗效及其对磁共振脑白质病变的影响。

方法

筛选2018年4月至2019年12月多中心符合入组标准的DEACMP患者36例,采用中央随机化分配原则,将21例纳入试验组,15例纳入对照组。对照组给予高压氧及常规治疗,试验组在对照组基础上加用丁苯酞注射液及丁苯酞胶囊治疗,共治疗90 d。收集2组患者在治疗前、治疗后1个月、3个月简易智能状态量表(MMSE)、Barthel指数(BI)评定量表、改良Ashworth分级以及头颅磁共振影像学资料等信息。采用t检验比较2组间不同时间MMSE评分、BI评分和脑白质脱髓鞘体积的差异,采用秩和检验比较不同时间2组间改良Ashworth分级的差异,采用χ2检验比较组间治疗有效率的差异,并对不同时间的MMSE评分、BI评分和改良Ashworth分级进行线性趋势检验。

结果

治疗3个月后,试验组的MMSE评分和BI评分高于对照组[(24.61±5.59)分 vs(15.64±10.95)分;(91.66±15.83)分 vs(62.85±38.11)分],而改良Ashworth分级低于对照组[0.0(0.0,0.0)vs 1.0(0.0,1.0)],差异均具有统计学意义(t=2.830,P=0.011;t=2.686,P=0.016;Z=3.618,P=0.004)。随着治疗时间的延长,试验组的MMSE评分、BI评分增加,而改良Ashworth分级下降,趋势检验均具有统计学意义(P均<0.05)。试验组治疗后3个月脑白质脱髓鞘体积比治疗后1个月时的体积小[(33 518±14 273)mm3 vs(57 394±18 973)mm3],差异具有统计学意义(P<0.05)。试验组患者治疗3个月后有效率高于对照组(95.0% vs 60.0%),差异具有统计学意义(χ2=6.937,P=0.013)。

结论

丁苯酞在促进DEACMP患者神经功能恢复,提高患者认知功能及日常生活自理能力,改善肌张力方面较常规治疗效果好,且丁苯酞可能促进DEACMP患者脑白质脱髓鞘的恢复。

Objective

To explore the effect of butylphthalide on delayed encephalopathy after carbon monoxide poisoning (DEACMP) and its effect on white matter lesions by magnetic resonance imaging (MRI).

Methods

Thirty-six DEACMP patients who met the criteria for admission were included and 21 patients were randomly enrolled into the trial group and the other 15 into the control group in multiple research centers from April 2018 to December 2019. The patients in the control group were received hyperbaric oxygen and routine treatment, and the trial group was treated with the same therapy as the control group plus the buphthalin treatment (injection and capsule) up to 90 days. Clinical data of the two groups of patients before treatment, 1 month and 3 months after the treatment were collected, including the mini-mental state examinination (MMSE), Barthel index rating scale (BI), the modified Ashworthscores, and head magnetic resonance imaging. The t-test was used forcomparing differences in MMSE scores, BI scores, and brain white matter demyelination volumes between 2 groups, rank-sum test for Ashworth scores between 2 groups, χ2 test for treatment efficiency, and linear trend tests for MMSE scores, BI scores, and modified Ashworth scores at different times.

Results

After 3 months of treatment, The MMSE and BI scores were higher in the trial group than in the control group [(24.61±5.59) score vs (15.64±10.95) score; (91.66±15.83) points vs (62.85±38.11) points], However, the modified Ashworth scores were lower than that in the control group [0.0 (0.0, 0.0) vs 1.0(0.0, 1.0)], the differences were all statistically significant (t=2.830, P=0.011; t=2.686, P=0.016; Z=3.618, P=0.004). The MMSE and BI scores increased in the trial group, while the modified Ashworth scores decreased with trend test-specific statistical significance (both P<0.05). The volume of brain white matter demyelination in the trial group at 3 months after treatment was smaller than that at 1 month after treatment [33 518±14 273) mm3 vs (57 394±18 973) mm3], and the difference was statistically significant (P<0.05). More Patients in the trial group were treated after 3 months than the number in the control group (95.0% vs 60.0%), and the difference was statistically significant (χ2=6.937, P=0.013).

Conclusion

Butylphthalide is more effective than the routine treatment in promoting the recovery of neurological function in patients with DEACMP, improving the cognitive function, self-care ability in daily life, and muscle tone. And buphthalein may promote the recovery of cerebral white matter demyelination in patients with DEACMP.
