Effect of Modified Huangqi Biejiatang Combined with Auricular Acupressure on Diabetic Peripheral Neuropathy of Qi-Yin Deficiency Syndrome and Serum MyD88/IκB Signaling Pathway / 中国实验方剂学杂志

ABSTRACT

Objective:To observe the effects of modified Huangqi Biejiatang combined with auricular acupressure on diabetic peripheral neuropathy （DPN） due to Qi and Yin deficiency and serum myeloid differentiation factor 88/inhibitor of nuclear factor-<italic>κ</italic>B （MyD88/I<italic>κ</italic>B） signaling pathway. Method:One hundred and forty cases were randomly divided into an observation group （<italic>n</italic>=70） and a control group （<italic>n</italic>=70）. In addition to routine treatments like dietary intervention and the regulation of fasting blood glucose （FBG） and blood pressure， the modified Huangqi Biejiatang combined with auricular acupressure was further provided in the observation group， while mecobalamine was administered in the control group. After four-week intervention， the toronto clinical scoring system （TCSS） score， traditional Chinese medicine （TCM） syndrome score， the conduction velocities of motor and sensory nerves （median nerve， common peroneal nerve， tibial nerve， and ulnar nerve）， glucose metabolism indexes ［fasting plasma glucose （FPG）， 2 h postprandial blood glucose （2 h PG）， and hemoglobin A1c （HbA1c）］， intestinal genera （<italic>Clostridium</italic>， <italic>Prauserella</italic>， <italic>Bacteroides</italic>， and <italic>Faecalibacterium</italic>）， as well as the serum MyD88， I<italic>κ</italic>B<italic>α</italic>， and phosphorylated I<italic>κ</italic>B<italic>α </italic>（p-I<italic>κ</italic>B<italic>α</italic>） levels in the MyD88/I<italic>κ</italic>B signaling pathway before and after treatment were observed in the two groups， for comparing their clinical efficacy and safety. Result:The total effective rate of the observation group was 85.3% （58/68）， which was higher than 48.5% （32/66） of the control group （<italic>χ</italic>²=6.143， <italic>P</italic><0.05）. The comparison with the control group revealed that the scores of TCSS and TCM syndrome， the levels of FPG， 2 h PG， HbA1c， MyD88， and p-I<italic>κ</italic>B<italic>α</italic>， as well as the abundances of <italic>Clostridium</italic> and <italic>Prauserella</italic> in the observation group were decreased （<italic>P</italic><0.05）， while the conduction velocities of motor and sensory nerves （median nerve， common peroneal nerve， tibial nerve， and ulnar nerve） were significantly accelerated （<italic>P</italic><0.05）. Besides， the abundances of <italic>Bacteroides</italic> and <italic>Faecalibacterium</italic> and I<italic>κ</italic>B<italic>α</italic> level were significantly elevated （<italic>P</italic><0.05）. The incidence of adverse reactions in the observation group was 1.5% （1/68）， lower than 12.1% （8/66） in the control group （<italic>χ</italic>²=4.328， <italic>P</italic><0.05）. Conclusion:The modified Huangqi Biejiatang combined with auricular acupressure alleviates DPN due to Qi and Yin deficiency， which may be attributed to the regulation of serum MyD88/I<italic>κ</italic>B signaling pathway.
