LiuWeiLuoBi Granule for the Treatment of Diabetic Peripheral Neuropathy
Study Details
Study Description
Brief Summary
Based on network pharmacology, Liuweiluobi Granule was screened to treat diabetes peripheral neuropathy with deficiency of the spleen and kidney and stasis-heat syndrome.In the preliminary animal experiment, it suggested that this granule had a significant protective effect on the peripheral motor nerves of diabetic peripheral neuropathy and the effect of anti-inflammation, and the prescription did not induce the death of zebrafish at a concentration of 1000 ug/mL, without any obvious toxicity. This study aims to evaluate the efficacy of Liuweiluobi Granule in improving neurotransmission function in patients with diabetic peripheral neuropathy through a pilot, randomized controlled study.

Outcome Measures
Primary Outcome Measures
- Mean maximal nerve conduction velocity [12 weeks]
Mean maximal conduction velocity of the common peroneal motor nerve (MCV) and sensory nerve (SCV)
Secondary Outcome Measures
- Michigan Diabetic Peripheral Neuropathy Score (MDNS) [Baseline, 4 weeks, 8 weeks and 12 weeks]
Michigan Diabetic Peripheral Neuropathy Score (MDNS) is a 46 point clinical score, with score ranging from 0 to 3 (score of 0, normal; 1, mild to moderate; 2, severe and score of 3, absent). The score is more high means a worse outcome.In MDNS vibration, pain, and light touch are assessed with a 128 Hz tuning fork, a pin, and a 10g filament, respectively. The outcome measures were performed by the investigator at baseline and at the eighth week.
- Toronto clinical scoring system (TCSS) [Baseline, 4 weeks, 8 weeks and 12 weeks]
Toronto clinical scoring system (TCSS) includes three parts: the symptom score of the symptom, the reflection score of the nerve and the evaluation score of the sensory function test. Symptoms include numbness, pain, and needle-like sensation in the lower extremities Feelings of weakness, weakness, instability in walking, and similar symptoms of the upper limbs, such as normal score of 0, 1 point for the presence of corresponding symptoms, a total of 6 points; nerve reflex including ankle reflex and knee reflex, bilateral score, normal score of 0, weakened 1 point, 2 points for disappearance, 8 points in total; sensory function test includes 5 items of pain, temperature, pressure, vibration, and position on the right big toe, 0 points for normal, 1 point for abnormality, 5 points in total With a total score of 19 points. With a score of 0 to 5 do not exist in the DPN, 6 to 8 are mild DPN, 9 to 11 are moderate DPN, 12 to 19 are severe DPN.
- Quantitative symptoms scales of DPN in Traditional Chinese medicine [Baseline, 4 weeks, 8 weeks and 12 weeks]
- HbA1c [Baseline, 4 weeks, 8 weeks and 12 weeks]
- Changes in the level of aldose reductase [to 12 weeks]
- Fasting blood glucose [Baseline, 4 weeks, 8 weeks and 12 weeks]
- 2 hrs postprandial blood glucose [Baseline, 4 weeks, 8 weeks and 12 weeks]
- Total lipids (TC) [Baseline, 4 weeks, 8 weeks and 12 weeks]
Lipid level
- triglycerides (TG) [Baseline, 4 weeks, 8 weeks and 12 weeks]
Lipid level
- high density lipoprotein cholesterol (HDL-C) [Baseline, 4 weeks, 8 weeks and 12 weeks]
Lipid level
- low density lipid Protein cholesterol (LDL-C). [Baseline, 4 weeks, 8 weeks and 12 weeks]
Lipid level
Other Outcome Measures
- Amino acids, lipid metabolites, vitamins, neurotransmitters and other metabolites [Baseline, 4 weeks, 8 weeks and 12 weeks]
Amino acids, lipid metabolites, vitamins, neurotransmitters and other metabolites will be analyzed and tested using targeted metabolic analysis.
