-
摘要:
目的 探究CT引导下脉冲射频(PRF)联合神经阻滞治疗头面部带状疱疹后神经痛(PHN)的疗效及可能机制。 方法 选择2021年2月—2023年8月连云港市第一人民医院收治的头面部PHN患者104例,采用随机数表法将其分为研究组(52例)与对照组(52例)。对照组给予神经阻滞治疗,研究组行CT引导下PRF联合神经阻滞治疗。治疗1个月后评价疗效及安全性,对比2组治疗前后疼痛视觉模拟评分(VAS)、匹兹堡睡眠质量指数(PSQI)、汉密尔顿焦虑/抑郁量表(HAMA/HAMD)评分,且治疗前后采血测定疼痛递质[β-内啡肽(β-EP)、P物质(SP)、降钙素基因相关肽(CGRP)、神经肽Y(NPY)]与炎症指标[白细胞介素(IL)-6、IL-26、CC趋化因子受体2(CCR2)]。 结果 治疗后,研究组总有效率高于对照组[90.38%(47/52) vs. 73.08%(38/52),P<0.05)];研究组VAS评分为(2.21±0.64)分,低于对照组的(3.37±1.00)分(F=802.273, P<0.001),研究组PSQI、HAMA及HAMD评分、血清疼痛递质及炎症指标水平均低于对照组(P<0.05);2组不良反应发生率比较,差异无统计学意义(P>0.05)。 结论 CT引导下PRF联合神经阻滞治疗头面部PHN安全有效,能减轻患者疼痛,其机制可能与抑制疼痛介质、降低血清IL-6、IL-26、CCR2水平有关。 Abstract:Objective To investigate the efficacy and possible mechanism of CT-guided pulse radiofrequency (PRF) combined with nerve block in the treatment of post-herpetic neuralgia (PHN) of the head and face. Methods A total of 104 patients with head and face PHN admitted to the First People ' s Hospital of Lianyungang from February 2021 to August 2023 were randomly divided into the study group (52 cases) and the control group (52 cases) using the random number table method. The control group underwent a nerve block procedure. The study group received CT-guided PRF combined nerve block treatment. Efficacy and safety were evaluated after 1 month of treatment, and changes in VAS, Pittsburgh sleep quality index (PSQI), Hamilton anxiety/depression scale (HAMA/HAMD) scores were compared between the two groups before and after treatment. Pain transmitters [β-endorphin (β-EP), substance P (SP), calcitonin gene-related peptide (CGRP), neuropeptide Y (NPY)] and inflammatory markers [interleukin-6, IL-26, CC chemokine receptor 2 (CCR2)] were measured in blood samples before and after treatment. Results Following treatment, the total effective rate in the study group was significantly higher [90.38% (47/52) vs. 73.08% (38/52), P < 0.05]; Additionally, the VAS score in the study group was (2.21±0.64) points, which was lower than that in the control group [(3.37±1.00) points, F=802.273, P < 0.001]. The PSQI, HAMA, HAMD scores, as well as serum pain transmitters and inflammatory marker levels, were significantly lower in the study group (P < 0.05). Conversely, there was no statistically significant difference in the incidence of adverse reactions (P>0.05). Conclusion CT-guided PRF combined with nerve block in the treatment of PHN of the head and face is safe and effective and can reduce pain in patients. The mechanism may be related to inhibition of pain mediators and reduction of serum levels of IL-6, IL-26 and CCR2. -
