Objective: To explore the effect of Mongolian medicine Naru-3 pills on the treatment of neuropathic pain (NP) with pregabalin combined with nerve block. Methods: Forty-one hospitalized patients in the department of pain medicine diagnosed with NP from October 2022 to September 2023 were selected, including 20 males and 21 females, aged 40-80 years, BMI ≥ 18.5 kg/m2. The patients were divided into two groups by random number table method: Mongolian medicine Naru-3 pills group (observation group, n = 20) and conventional treatment group (control group, n = 21). The control group received conventional treatment: oral pregabalin capsule combined with ultrasound-guided nerve block in pain area. The observation group was added oral administration of Mongolian medicine Naru-3 pills (2 g/10 capsules) on the basis of conventional treatment, taking 3-5 capsules orally before going to bed every night for 2 weeks. The numerical rating scale (NRS) pain score, short-form McGill pain questionnaire (SF-MPQ) score, and Pittsburgh sleep quality index (PSQI) were recorded before treatment and 2 weeks, 1 month, and 2 months after the treatment. The serum concentrations of IL-6, IL-8, IL-1β, and TNF-α were detected by enzyme-linked immunosorbent assay (ELISA) 1 day before treatment and 2 weeks after treatment. Occurrence of adverse reactions during treatment such as nausea, vomiting, bloating, palpitations, drowsiness, and dizziness were recorded. Results: Compared with 1 day before treatment, NRS pain score, SF-MPQ score, and PSQI were lower in both groups 2 weeks, 1 month, and 2 months after the treatment (P < 0.05), the serum concentrations of IL-6, IL-1β, and TNF-α were reduced in both groups 2 weeks after the treatment (P < 0.05). Compared with the control group, NRS pain score, SF-MPQ score, and PSQI were lower in the observation group 2 weeks, 1 month, and 2 months after the treatment (P < 0.05); the serum concentrations of IL-6, IL-1β, and TNF-α were reduced in the observation group 2 weeks after the treatment (P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups. Conclusion: Mongolian Naru-3 pills combined with conventional therapy can effectively reduce the pain of NP patients, improve the quality of sleep of patients, and may have the effect of regulating neuroinflammation. |
