生物信息红外肝病治疗仪对肝硬化患者肝脏血供及肝纤维化的影响
Effect of bioinformatics infrared liver disease therapeutic instrument on hepatic blood supply and liver fibrosis in patients with liver cirrhosis
目的 观察生物信息红外肝病治疗仪(BILT肝病治疗仪)对肝硬化患者肝脏门静脉血流及肝、脾硬度的影响,初步探讨BILT肝病治疗仪的疗效和机制。 方法 纳入2017年10月—2021年12月在上海中医药大学附属曙光医院门诊或住院的代偿期肝硬化患者78例,完成12周疗程者68例,随机分为肝病治疗仪组(治疗组)和模拟治疗仪组(对照组),每组34例。在基础治疗的同时,两组分别予以BILT肝病治疗仪或模拟治疗仪照射,2次/d,30 min/次,疗程12周。比较治疗前后肝功能、肾功能、血常规等实验室指标,肝、脾超声形态,多普勒彩色血流检测(肝门静脉直径、截面积、平均流速、最高流速、平均流量)及肝、脾硬度检测。符合正态分布的计量资料两组间比较采用成组t检验;非正态分布的计量资料两组间比较采用非参数Mann-Whitney U秩和检验;计数资料组间比较采用χ²检验。各组内治疗前后数据,先进行配对样本相关性检验,若显著相关,则采取配对样本t检验或非参数相关样本Wilcoxon符号秩检验。 结果 配对样本相关性检验显示,脾脏超声衰减参数治疗前后无相关性,提示FibroTouch 对于脾脂肪的检测结果不适用于统计分析。两组12周治疗前后差值的组间比较显示,治疗组12周后门静脉直径、截面积、平均流量的增加值及肝硬度值的降低值均明显优于对照组(P值均0.05)。两组在0周治疗前和12周治疗后,BILT肝病治疗仪照射30 min的即刻效应比较显示,治疗组门静脉直径、截面积、平均流速、平均流量较照射前均明显增加(P值均0.05),而对照组照射前后比较,差异均无统计学意义(P值均0.05);两组间照射前后差值比较显示,除0周时门静脉最高流速外,治疗组治疗前后差值均大于对照组(P值均0.05)。两组均无不良事件发生。 结论 BILT肝病治疗仪可改善肝硬化患者肝脏门静脉血流并减轻肝硬度/肝纤维化程度。
Objectives To investigate the effect of the Bioinformatics Infrared Liver Therapeutic (BILT) instrument on portal vein blood flow, liver stiffness, and spleen stiffness in patients with liver cirrhosis, and to preliminarily explore the therapeutic effect and mechanism of the BILT instrument. Methods A total of 78 patients with compensated liver cirrhosis who attended the outpatient service or were hospitalized in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from October 2017 to December 2021 were enrolled, among whom 68 patients completed the 12-week treatment and were randomly divided into BILT group and simulated instrument group, with 34 patients in each group. In addition to basic treatment, the patients in the BILT group received irradiation with the BILT instrument, while those in the simulated instrument group received irradiation with the simulated instrument, for 30 minutes each time, twice a day; the course of treatment was 12 weeks for both groups. The two groups were compared in terms of laboratory markers (liver function, renal function, and routine blood test results), liver and spleen ultrasound morphology, color Doppler blood flow detection (portal vein diameter, portal vein cross-sectional area, mean portal vein velocity, peak portal vein velocity, and mean portal vein flow), and liver/spleen stiffness measurement before and after treatment. The independent samples t-test was used for comparison of normally distributed continuous data between two groups, and the non-parametric Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between groups. The paired samples correlation test was performed for the data before and after treatment within each group, and the paired samples t-test or the non-parametric Wilcoxon signed-rank test was performed for data with significant correlations. Results The paired samples correlation test showed no correlation in spleen attenuation parameter before and after treatment, suggesting that the results of spleen fat measured by FibroTouch could not be used for statistical analysis. After 12 weeks of treatment, compared with the control group, the treatment group had significantly greater increases in portal vein diameter, portal vein cross-sectional area, and mean portal vein flow and a significantly greater reduction in liver stiffness measurement (all P0.05). At week 0 before treatment and after 12 weeks of treatment, comparison of the immediate effect after 30 minutes of BILT irradiation showed that the treatment group had significant increases in portal vein diameter, portal vein cross-sectional area, mean portal vein velocity, and mean portal vein flow (all P0.05), while the control group showed no significant changes after irradiation (all P0.05); compared with the control group, the treatment group had significantly greater changes in all indicators except peak portal vein flow at week 0 (all P0.05). No adverse events were observed in either group. Conclusion The BILT instrument can improve portal vein blood flow in the liver and alleviate liver stiffness/fibrosis in patients with liver cirrhosis.
