Danggui Sini decoction for treating diabetic peripheral neuropathy

Abstract

Background: Diabetic peripheral neuropathy (DPN) is one of the most common chronic complications of diabetic patients, which seriously affects the quality of life of patients. At present, mainstream drugs have problems such as poor efficacy and side effects. Traditional Chinese medicine (TCM) has extensive clinical experience in the prevention and treatment of diabetes and chronic complications, and it also shows clear advantages in the treatment of DPN. Clinical studies have confirmed that Danggui Sini decoction (DSD), a TCM decoction, can improve the clinical symptoms and signs of DPN patients. Therefore, we will conduct a systematic review to clarify the effectiveness and safety of DSD for DPN. Methods: We will search every database from the built-in to October 2020. Chinese literature comes from CNKI, Wanfang, VIP, and CBM databases. English literature mainly searches Cochrane Library, PubMed, Web of Science, and EMBASE. At the same time, we will also search for clinical registration tests and gray literatures. This study only screened clinical randomized controlled trials (RCT) for DSD for DPN. The two researchers independently conducted literature selection, data extraction and quality assessment. Dichotomous data is represented by relative risk (RR), continuous data is represented by mean difference (MD) or standard mean deviation (SMD), and the final data is fixed effect model (FEM) or random effect model (REM), depending on whether it exists Heterogeneity. The main result is clinical efficacy and nerve conduction velocity. Fasting blood glucose, 2 hours postprandial blood glucose, blood lipid, hemorheology, and adverse events are secondary results. Finally, a meta-analysis was conducted through Review Manager software version 5.3. Results: This study will conduct a comprehensive analysis based on the currently released DSD data for the treatment of DPN and provide high-quality evidence of clinical efficacy and safety. Conclusion: This systematic review aims to provide new options for DSD treatment of DPN in terms of its efficacy and safety. Ethics and dissemination: The review is based solely on a secondary study of published literatures and does not require ethics committee approval. Its conclusion will be disseminated in conference papers, magazines, or peer-reviewed journals. INPLASY registration number: INPLASY202040157.

Regulation of transient receptor potential channels by traditional Chinese medicines and their active ingredients

“…Paeoniae Radix Alba is the dried root of Paeonia lactiflora pall, pertaining to Ranunculaceae, which is bitter, sour and slightly cold in nature ( State Pharmacopoeia Commission, 2020 ; Zhang and Ye, 2020 ). Using Western blot, Zhang showed the effect of Paeoniae Radix Alba on TRP in DRG neurons and found that Paeoniae Radix Alba could restore the expression levels of TRPV1 and TRPM8 to normal levels, thus relieving chronic constriction injury of the sciatic nerve ( Zhang, 2020 ).…”

Researching the molecular mechanisms of Taohong Siwu Decoction in the treatment of varicocele-associated male infertility using network pharmacology and molecular docking: A review

“…In recent years, network pharmacology has been widely used to elucidate the mechanism of action of traditional Chinese medicine (TCM) in the treatment of diseases, and to screen the active ingredients and key targets of TCM by constructing a network of compounds and targets. [3,4] As we all know, molecular docking technology plays a key role in drug design, development, and research. By calculating the binding energy of different conformations (small molecules binding to protein receptors), it is convenient to explore potential active compounds for the treatment of diseases.…”

Meta-analysis of angelica Sini Decoction in the treatment of diabetic peripheral neuropathy

“…Chinese medicine believes that a variety of reasons lead to Yin Jin deficiency, blood stasis, Yin damage and inability of Yang Qi or Yang Qi can not reach the end of the limbs, DPN symptoms gradually appear. It was found that Angelica Sini Decoction in "Treatise on Febrile Diseases" can play a role by regulating NF-κb [4] , RhoA/ROCK [5] , Ca 2+ , AGEs-RAGE [6][7][8] and other signaling pathways, or by reducing inflammatory factors [9] and improving the expression levels of TrkA protein [10] . The clinical data of Angelica Sini Decoction in the treatment of DPN were analyzed to provide more ideas for the treatment of DPN.…”
