Analysis of MDA, SOD, TAOC, MNCV, SNCV, and TSS scores in patients with diabetes peripheral neuropathy.

To explore the impact of score in patients with diabetes peripheral neuropathy (DPN) treated with traditional Chinese medicine package (TCMP) plus red light therapy and lipoic acid on malondialdehyde (MDA), erythrocyte superoxide dismutase (SOD), total antioxidant capacity (TAOC), motor nerve conduction velocity (MNCV), sensory nerve conduction velocity (SNCV), and Toronto Clinical Scoring System (TSS). A total of 108 patients with DPN hospitalized in the hospital were chosen and divided into groups with the random number table. In the control group (CG) 54 patients were treated with conventional lipoic acid, and 54 patients in the experimental group (EG) accepted TCMP plus red light on the basis of the CG. The MDA, SOD, TAOC, MNCV, SNCV, and TSS scores before treatment and after treatment were compared between the two groups. Before treatment, there was no statistically significant difference in the levels of oxidation indicators, nerve conduction velocity, and symptom scores between the two groups (P > 0.05). After treatment, the MDA in the EG was lower than that in the CG, with a statistical significance difference (P < 0.05). The SOD and TAOC in the EG were higher than those in the CG, and the difference was statistically significant (P < 0.05). The MNCV and SNCV of median nerve, common peroneal nerve, and tibial nerve in the EG were significantly higher than those in the CG (P < 0.05). The TSS score of the EG was lower than that of the CG, and the difference was statistically significant (P < 0.05). The treatment of patients with DPN with lipoic acid plus TCMP and red light therapy can improve the symptoms and signs of disease, promote the recovery of motor and sensory conduction velocity, and optimize the body oxidation indicators.

A Case Report on the Ayurvedic Management of Diabetic Peripheral Neuropathy

Diabetic neuropathy is one of the most common microvascular complications of diabetes mellitus. It has a significant impact in lowering quality of life (QOL) of diabetic patients. Currently, there is no effective management rather than tight blood sugar control. Hence an effective management for diabetic peripheral neuropathy (DPN) has to be deduced. A 41‑year‑old female patient, who was a known case of diabetes mellitus presenting with the symptoms of diabetic peripheral neuropathy was treated with a combination of Ayurvedic internal as well as external therapies, considering the treatment protocol of Prameha upadrava and Vatarakta chikitsa. The symptoms were assessed before and after treatment using the Toronto Clinical Scoring System. Significant improvement was seen in all the scores after the treatment. This case elicited that DPN can be successfully managed by Ayurvedic treatment.

Eleven neurology-related proteins measured in serum are positively correlated to the severity of diabetic neuropathy

About 20% of patients with diabetes suffer from chronic pain with neuropathic characteristics. We investigated the multivariate associations between 92 neurology-related proteins measured in serum from 190 patients with painful and painless diabetic neuropathy. Participants were recruited from the Pain in Neuropathy Study, an observational cross-sectional multicentre study in which participants underwent deep phenotyping. In the exploration cohort, two groups were defined by hierarchical cluster analyses of protein data. The proportion of painless vs painful neuropathy did not differ between the two groups, but one group had a significantly higher grade of neuropathy as measured by the Toronto Clinical Scoring System (TCSS). This finding was replicated in the replication cohort. Analyzing both groups together, we found that a group of 11 inter-correlated proteins (TNFRSF12A, SCARB2, N2DL-2, SKR3, EFNA4, LAYN, CLM-1, CD38, UNC5C, GFR-alpha-1, and JAM-B) were positively associated with TCSS values. Notably, EFNA4 and UNC5C are known to be part of axon guidance pathways. To conclude, although cluster analysis of 92 neurology-related proteins did not distinguish painful from painless diabetic neuropathy, we identified 11 proteins which positively correlated to neuropathy severity and warrant further investigation as potential biomarkers.

Clinical effect of acupuncture combined with medication on diabetic peripheral neuropathy and its influence on serum lipid metabolism

To observe the clinical effect on diabetic peripheral neuropathy (DPN) treated with acupuncture combined with medication and explore its effect mechanism. Sixty-two patients of DPN were randomly divided into a combined therapy group (31 cases) and a medication group (31 cases, 2 cases dropped out); besides, 20 healthy subjects were recruited as a normal group. On the base of routine intervention, in the medication group, thioctic acid capsules were administrated orally, 0.2 g each time, 3 times a day. In the combined therapy group, besides the medication as the medication group, acupuncture was performed on bilateral Quchi (LI 11), Waiguan (TE 5), Hegu (LI 4), Tianshu (ST 25), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3) and the needles were retained for 30 min, acupuncture was delivered once daily, 6 times a week. The duration of treatment was 4 weeks in the two groups. The score of Toronto clinical scoring system (TCSS), the nerve conduction velocity of median nerve (MN) and common peroneal nerve (CPN) were observed before and after treatment in the two intervention groups; and the serum lipid metabolism was detected before and after treatment in the two intervention groups and the normal group. Compared with that before treatment, the scores of TCSS were reduced in the combined therapy group and the medication group (P<0.05) after treatment, and the score decrease in the combined therapy group was larger than that of the medication group (P<0.001). The motor nerve conduction velocity and the sensory nerve conductive velocity of MN and CPN after treatment all increased in the combined therapy group and the medication group compared with those before treatment (P<0.05), and the improvements in the combined therapy group were larger than those of the medication group (P<0.001). Before treatment DPN patients had 365 differential lipid metabolites, including sphingosine (SPH, d18:0), involved in the inositol phosphate metabolism, compared with the subjects of the normal group. There were 103 differential lipid metabolites in the medication group before and after treatment, including lysophosphatidyl ethanolamine (LPE, 18:1/0:0), participated in glycerophospholipid metabolism. In the combined therapy group, before and after treatment, there were 99 differential lipid metabolites, including lysophosphatidylcholine (LPC, 18:0/0:0), participated in the neuroactive ligand-receptor interaction. Acupuncture greatly affected 50 lipid metabolites such as lysophosphatidic acid (LPA, 0:0/22:6), LPA(0:0/18:2) and LPC(O-18:0), which was mainly involved in glycerophospholipid metabolism. Acupuncture combined with medication ameliorates the symptoms and the nerve conduction velocity in DPN patients, which may be related to the regulation of serum lipid metabolism.

Ayurvedic Treatment Modalities of Diabetic Peripheral Neuropathy

Diabetic peripheral neuropathy is the damage of the nerves due to the uncontrolled diabetes. It can affect any of the neurons can affect any of the neurons. Diabetic distal symmetric sensory and sensorimotor polyneuropathy is the most prevalent type of diabetic neuropathy. The symptoms appear as sensory loss, first in the toes and progressively moving up the legs, fingers, and arms over time. Tingling sensation, Burning sensation, Deep aching pain are other related symptoms. A patient age 54 years with diabetes for past 15 years, hypertension, dyslipidemia, complains of burning sensation of both feet (right&gt;left), numbness, pricking pain, unsteadiness while walking, brownish red discolouration of both lower limbs. The symptoms were gradual in onset. Nerve Conduction Study showed axonal type of motor and sensory affecting peroneal nerve neuropathy. He admitted in Vaidyaratnam Ayurveda College Hospital, done Vibrotherm Neuropathy Analyzer and revealed small and large fibre neuropathy with severe loss of sensations. The main intention of the study is to improve the quality of life of the patient by reducing the symptoms that is disturbing his day today routine. Patient given with anti diabetic Ayurvedic formulations internally. Externally Rookshana, Vatahara, Brimhana treatments were done. After the treatment, Michigan neuropathy screening instrument, diabetic Neuropathy symptom score, Toronto clinical scoring system score were reduced. Neuropathy Analyzer showed mild to moderate loss of sensation. By adopting Prameha hara chikitsa coupled with Vata vyadhihara chikitsa, complications of diabetes can be managed. It is important to focus on diet and regimen since diabetes is a lifestyle disorder and, in ayurveda it is considered as an Anushangi Vyadhi.

Long-term efficacy and safety of Huangqi ()-based Traditional Chinese Medicine in diabetic peripheral neuropathy: a Meta-analysis of randomized controlled trials.

To assess the long-term effectiveness of Huangqi (Radix Astragali Mongolici, HQ)-based Traditional Chinese Medicine (TCM) in the treatment of diabetic peripheral neuropathy (DPN). Nine databases were searched to retrieve available randomized controlled trials that compared HQ-based TCM and Western Medicines in the treatment of DPN. The methodological quality of the included studies was assessed using the Cochrane bias risk tool, and RevMan 5.4 was used for data analysis. The effect estimates of interest were risk ratio (RR), mean difference (MD) or standardized mean difference (SMD) with 95% confidence interval (CI). The results from 48 available studies assessing 3759 patients demonstrated that cases administered HQ-based TCM [RR = 1.30, 95% CI (1.21, 1.40), P < 0.000 01] or HQ-based TCM combined with Western Medicines [RR = 1.25, 95% CI (1.19, 1.31), P < 0.000 01] exhibited higher total efficacy rates than individuals who received Western Medicine alone. The results showed that the HQ-based TCM group had decreased Toronto Clinical Scoring System scores [MD =－1.50, 95% CI (－1.83, －1.17), P < 0.000 01], and reduced serum interleukin 6 [SMD = －0.57, 95% CI (－0.87, －0.27), P = 0.0002] and tumor necrosis factors-α levels [SMD = －0.60, 95% CI (－0.95, －0.25), P = 0.0009]. In addition, both HQ-based TCM and HQ-based TCM combined with Western Medicine increased nerve conduction velocity and decreased glycaemia compared with Western Medicine alone. In terms of blood lipids, oxidative stress and adverse drug reactions, there were no significant differences between the HQ-based TCM groups and the Western Medicine control group. The current Meta-analysis revealed that HQ-based TCM yields higher efficacy and safety than Western Medicine alone for the treatment of DPN, although further well-designed RCTs are required to validate these findings.

Investigating the Effectiveness of Electroacupuncture for Diabetic Peripheral Neuropathy and Exploring the Feasibility of Infrared Thermography as an Efficacy Assessment Tool: Study Protocol for a Randomized Controlled Trial.

Diabetic peripheral neuropathy (DPN) affects patients' quality of life significantly. To date, selecting the appropriate treatment remains challenging. While electroacupuncture (EA) has shown promise as an effective adjunct therapy for DPN, and infrared thermography (IRT) has been considered as a potential predictor of treatment efficacy, the evidence for both remains inconclusive. As such, the objectives of this trial are twofold: to ascertain the efficacy of EA for DPN, and to explore the feasibility of IRT as an adjunctive objective tool for efficacy assessment. The study was designed as a randomized, parallel, controlled trial. It spanned over 6 weeks of treatment and an additional 4 weeks of follow-up. 104 eligible participants will be stratified for severity of disease: mild with Toronto clinical scoring system(TCSS) score 6-8, moderate (TCSS score 9-11), and severe (TCSS score 12-19), and each level will be randomised in a 1:1 ratio into a EA group and waiting-list group. The waiting-list group received only the current conventional medication, while the EA group received an additional 12 EA sessions on top of the conventional medication. The primary outcome indicators is nerve conduction velocity (NCV), which will be tested at the baseline and week 6. Total clinical efficiency, TCSS, Clinical symptoms score of Traditional Chinese Medicine (TCM), Patient global impression of change(PGIC), Temperature of regions of interest (ROIs), and Physico chemical examination will be used as secondary outcome indicators. In addition, safety assessment will be determined based on adverse events during the trial. The expected results of this study will determine whether EA improves efficacy in the treatment of DPN with an acceptable safety profile, and investigating variations in the efficacy of EA across different levels of DPN severity. Furthermore, it will explore the viability of IRT as an objective measure for evaluating treatment effectiveness for DPN. ClinicalTrials.gov identifier, NCT06054087.

Acupuncture for the treatment of diabetic peripheral neuropathy in the elderly: a systematic review and meta-analysis.

Diabetic peripheral neuropathy (DPN) is one of the most common complications of diabetes mellitus, often causing pain or numbness in the patient's limbs and even leading to amputation and death. Elderly patients with DPN usually have higher morbidity and more severe results. Acupuncture has been widely used as an effective treatment for DPN in China. However, the efficacy of acupuncture in the treatment of DPN remains unclear. In this review, we aimed to explore the impact of acupuncture in alleviating symptoms of DPN. Six databases were searched from inception to October 2023. We searched Medline, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and three Chinese databases, namely China National Knowledge Infrastructure (CNKI), SinoMed, and Wanfang. All randomized controlled trials related to the effect of acupuncture on DPN will be included. There was no restriction in language or publication year. The primary outcome is the response rate. The secondary outcomes are the Toronto clinical scoring system (TCSS), nerve conduction velocities (NCVs), and blood glucose before and after the treatment. Two researchers will be responsible for the selection of study, data extraction, and assessment of study quality independently. RevMan V5.1.0 software will be used to assess the risk of bias and generate data. We searched 4518 studies, among which 9 RCTs were considered eligible. Overall, acupuncture treatment had a higher response rate than controls (relative risk (RR), -2.87 [95% confidence interval (CI), -5.27 to -0.48], p = 0.02) and significantly alleviated the symptoms of DPN patients, reduced their blood glucose levels, and improved their NCVs compared to the control group. This study will provide a high-quality synthesis of current available evidence for the clinical treatment of DPN with this therapy. The results suggested that acupuncture might be effective in improving symptoms of DPN in elderly patients. Owing to the overall low quality of the literature included, we need more large-sample, high-quality, and low-bias studies to prove it.

Cognition and motion dysfunction-associated brain functional network disruption in diabetic peripheral neuropathy.

Neuroimaging studies have demonstrated extensive brain functional alterations in cognitive and motor functional areas in Type 2 diabetes mellitus (T2DM) with diabetic peripheral neuropathy (DPN), suggesting potential alterations in large-scale brain networks related to DPN and associated cognition and motor dysfunction. In this study, using resting-state functional connectivity (FC) and graph theory computational approaches, we investigated the topological disruptions of brain functional networks in 28 DPN, 43 T2DM without DPN (NDPN), and 32 healthy controls (HCs) and examined the correlations between altered network topological metrics and cognitive/motor function parameters in T2DM. For global topology, NDPN exhibited a significantly decreased shortest path length compared with HCs, suggesting increased efficient global integration. For regional topology, DPN and NDPN had separated topological reorganization of functional hubs compared with HCs. In addition, DPN showed significantly decreased nodal efficiency (Enodal ), mainly in the bilateral superior occipital gyrus (SOG), right cuneus, middle temporal gyrus (MTG), and left inferior parietal gyrus (IPL), compared with NDPN, whereas NDPN showed significantly increased Enodal compared with HCs. Intriguingly, in T2DM patients, the Enodal of the right SOG was significantly negatively correlated with Toronto Clinical Scoring System scores, while the Enodal of the right postcentral gyrus (PoCG) and MTG were significantly positively correlated with Montreal Cognitive Assessment scores. Conclusively, DPN and NDPN patients had segregated disruptions in the brain functional network, which were related to cognition and motion dysfunctions. Our findings provide a theoretical basis for understanding the neurophysiological mechanism of DPN and its effective prevention and treatment in T2DM.

Effect of miR-146a polymorphism on lipoic acid therapy in patients with T2DM peripheral polyneuropthy.

For investigating the impact of miR-146a rs2910164 polymorphism on the therapeutic efficacy of lipoic acid therapy in patients with type 2 diabetes mellitus (T2DM) peripheral neuropathy (DPN). 106 T2DM-DPN patients in our hospital from Jan. 2020- 2022 were selected. The probe detection method was utilized to determine the polymorphism of the miR-146a rs2910164 gene in peripheral blood. All patients were treated with zinc sulfate for 3 weeks period. According to the treatment effect, 37 patients who were ineffective in treatment will be divided into an ineffective group, and 79 patients who were effective in treatment will be divided into an effective group. The condition of miR-146a gene peptides was analyzed after treatment in both groups. The motor nerve conduction velocity (MNCV), sensory nerve conduction velocity (SNCV), and Toronto Clinical Scoring System (TCSS) scores of the median nerve and common peroneal nerve with different genotypes were compared between the 2 sets. The genotype frequencies of alleles G, GG, and GC in the valid group were lower than those in the invalid group; After treatment, MNCV and SNCV of CC genotype median nerve and common peroneal nerve in DPN patients were higher than those before treatment; The TCSS scores of the three genotypes less than post-treatment. The above results showed statistically significant differences (P<0.05). Lipoic acid is influenced by the miR-146a polymorphism gene in the treatment of T2DM-DPN patients, with the CC genotype having a lower susceptibility and the best clinical treatment effect.

Prevalence and risk factors of diabetic peripheral neuropathy: A population-based cross-sectional study inChina.

To assess the prevalence of diabetic peripheral neuropathy (DPN) and its risk factors in the type 2 diabetes mellitus (T2DM) population. This cross-sectional study enroled patients with T2DM between July and December 2017 from 24 provinces in China. Diabetic peripheral neuropathy and its severity were assessed by the Toronto clinical scoring system, neuropathy symptoms score (NSS) and neuropathy disability score. The prevalence of DPN and its risk factors were analysed. A total of 14,908 patients with T2DM were enroled. The prevalence of DPN was 67.6%. Among 10,084 patients with DPN, 4808 (47.7%), 3325 (33.0%), and 1951 (19.3%) had mild, moderate, and severe DPN, respectively. The prevalence of DPN in females was higher than in males (69.0% vs. 66.6%, P=0.002). The prevalence of DPN increased with age and course of diabetes and decreased with body mass index (BMI) and education level (all P for trend <0.05). The comorbidities and complications in patients with DPN were higher than in those without DPN, including hypertension, myocardial infarction, diabetic retinopathy, and diabetic nephropathy (all P<0.001). Age, hypertension, duration of diabetes, diabetic retinopathy, diabetic nephropathy, glycated haemoglobin, high-density lipoprotein cholesterol, and lower estimated glomerular filtration rate were positively associated with DPN, while BMI, education level, fasting C-peptide, and uric acid were negatively associated with DPN. Among patients with T2DM in China, the prevalence of DPN is high, especially in the elderly, low-income, and undereducated patients.

Effects of Mindfulness Training Combined with Tai Chi in Patients with Diabetic Peripheral Neuropathy.

Diabetic peripheral neuropathy (DPN) is one of the most prevalent chronic complications of diabetes. One of its crucial therapy approaches is mind-body exercise. Recently, various exercise modalities, including stepping, resistance, aerobics, balance, and whole-body vibration, were investigated to construct the most suitable form of exercise for patients with DPN. The purpose of this study is to describe a standard protocol for mindfulness training combined with Tai Chi. The convenience sampling method was used to select 90 patients with DPN who met the inclusion and exclusion criteria from three communities. The three communities were randomly divided into the control group (CG), the Tai Chi group (TCG), and the mindfulness training combined with the Tai Chi group (MTCG). The CG was given routine health education guidance once a month, a total of three times. Based on the CG, the TCG practiced Tai Chi three times; the MTCG received mindfulness training combined with Tai Chi exercise a week for a total of 12 weeks. Before the intervention and 12 weeks after the intervention, the clinical symptoms, neurological function, attention awareness level, pain, and quality of life of the subjects were evaluated by Toronto Clinical Scoring System (TCSS), Mindful Attention Awareness Scale (MAAS), Visual analog scale (VAS), Diabetes Specificity Quality of life Scale (DSQL) and tumor necrosis factor-α. Overall, the addition of mindfulness training to Tai Chi effectively enhances the exercise effects of Tai Chi. Therefore, mindfulness training combined with Tai Chi is worthy of promotion and application.

Gut microbiota modulate distal symmetric polyneuropathy in patients with diabetes

The pathogenic mechanisms underlying distal symmetric polyneuropathy (DSPN), a common neuropathy inpatients with diabetes mellitus (DM), are not fully understood. Here, we discover that the gut microbiota from patients with DSPN can induce a phenotype exhibiting more severe peripheral neuropathy in db/db mice. In a randomized, double-blind, and placebo-controlled trial (ChiCTR1800017257), compared to 10 patients who received placebo, DSPN was significantly alleviated in the 22 patients who received fecalmicrobiotatransplantsfrom healthy donors, independent of glycemic control. The gut bacterial genomes that correlated with the Toronto Clinical Scoring System (TCSS) score were organized in two competing guilds. Increased guild 1, which had higher capacity in butyrate production, and decreased guild 2, which harbored more genes in synthetic pathway of endotoxin, were associated with improved gut barrier integrity and decreased proinflammatory cytokine levels. Moreover, matched enterotype between transplants and recipients showed better therapeutic efficacy with more enriched guild 1 and suppressed guild 2. Thus, changes in these two competing guilds may play a causative role in DSPN and have the potential for therapeutic targeting.

Predictive value of ultrasonography in polyneuropathy diagnosis: electrophysiological and ultrasonographic analysis.

Peripheral neuropathy may cause serious complications such as foot ulcers and Charcot joint which can prevent by early diagnosis. We aimed to analyze the diagnostic value of ultrasonographic measurements of nerves and muscles in distal symmetric axonal polyneuropathy (DSAP). Study included 51 DSAP patients and 51 controls. Nerve conduction studies were performed. Median, ulnar, tibial, superficial peroneal, and sural nerves and the abductor pollicis brevis (APB), abductor digiti minimi (ADM), first dorsal interosseous (FDI), extensor digitorum brevis (EDB), abductor hallucis (AH) and tibialis anterior (TA) muscles were evaluated with ultrasound. The Toronto clinical scoring system (TCSS) was used to assess the severity of neuropathy. The median, ulnar, and tibial nerve cross-sectional areas (CSA) were higher in the DSAP group (p = 0.025, p = 0.011, p < 0.001 respectively) while superficial peroneal and sural nerve CSAs were not differed. Only AH and EDB ultrasonographic findings from the muscles differed between the two groups. Effect of diabetes and DSAP on sonographic findings were assessed with two-way ANOVA. Results indicated that only DSAP had a significant effect on sonographic nerve and muscle examination. The area under the ROC curve was 0.831 ± 0.042 for tibial nerve CSA (p < 0.001) with a cut-off value of 15.5 mm2 (sensitivity 74% and specificity 83%). Median, ulnar and tibial nerve CSAs were found to be larger in polyneuropathy patients and they were associated with the clinical and electrophysiological severity of polyneuropathy. ROC analysis showed that tibial nerve CSA may have a predictive value in the diagnosis of DSAP.

The Association between Waist Hip Ratio and Severity of Diabetic Peripheral Neuropaty in Diabetes Melitus Type 2 by Using Toronto Clinical Scoring System

Introduction: Diabetic neuropathy is a common and progressive microvascular complication of diabetes, so early detection and prevention is very important. Other modifiable risk factors such as hypertension, dyslipidemia, or central obesity can be managed. Central obesity with insulin resistance is a key pathophysiological factor in the metabolic syndrome. Waist hip ratio (WHR) has been proposed as a tool for detecting central obesity. Toronto Clinical Scoring System (TCSS) is a diabetic neuropathy scoring system that has high sensitivity and specificity. The aim of this study was to determine the relationship between waist hip ratio and the severity of peripheral diabetic neuropathy in type 2 Diabetes Melitus (DM) according to the Toronto Clinical Scoring System (TCSS). Method: This study used a cross-sectional design. Sampling was conducted at the Endocrinology Polyclinic and Neurology Polyclinic Hospital H. Adam Malik Medan. The research sample was taken as many as 45 subjects consecutively. TCSS examination is performed to diagnose and determine the severity of diabetic neuropathy Therefore, waist hip ratio was calculated to assess central obesity. Data analysis using Chi Square test. Results: On the demographic characteristics of the research subjects were male, age range 51-60 years, high school education level, not working, history of DM 5-10 years. The mean value of WHR is 0.87±0.051. Median TCSS Score 10 (6-16). The majority of subjects had mild diabetic peripheral neuropathy. Patients with central obesity had a grading of neuropathy that was classified as severe as many as 13 people (56.5%), moderate as many as 7 people (30.4%), and mild as many as 3 people (13.0%). While patients who are not obese have a grading of neuropathy that is classified as severe as many as 1 person (4.5%), moderate as many as 5 people (22.7%), mild as many as 16 people (72.7%). Based on the Chi Square test, it was found that there was a significant association between the waist hip ratio and the severity of diabetic peripheral neuropathy in type 2 DM patients with p&lt;0.01. Conclusion: There is a statistically significant association between waist hip ratio and the severity of diabetic neuropathy in type 2 DM with p &lt; 0.01.

Improving Effects of Peripheral Nerve Decompression Microsurgery of Lower Limbs in Patients with Diabetic Peripheral Neuropathy

Peripheral nerve decompression microsurgery can relieve nerve entrapment and improve the symptoms of DPN. However, postoperative tissue adhesion will produce new pressure on the nerves, affecting the surgical efficacy. In this study, a nerve conduit was used in the peripheral nerve decompression microsurgery to prevent postoperative adhesions, and the role of the nerve conduit in surgical nerve decompression was explored. A total of 69 patients with DPN were recruited and randomly divided into three groups: the nerve conduit group, conventional surgery group, and control group. Two weeks before surgery and 6 months after surgery, patients in each group were clinically tested using the visual analog scale (VAS) score, neurophysiological test, Toronto clinical scoring system (TCSS) score, and two-point discrimination (2-PD) test. The patients' symptoms in the nerve conduit group were relieved to varying degrees, and the relief rate reached 90.9%; the treatment efficacy was higher than that in the other groups. The postoperative nerve conduction velocity (NCV) in the two surgical groups was significantly higher than that before the surgery, and the difference between the nerve conduit group and the conventional surgery group was statistically significant (p < 0.05). For the 2-PD test, there was a statistically significant difference between the two surgical groups (p < 0.05). The TCSS score in the two surgical groups was significantly higher than that in the control group (p < 0.01). There was a significant difference in the TCSS scores between the nerve conduit group and the conventional surgery group (p < 0.05). The nerve conduit could further improve the efficacy of peripheral nerve decompression microsurgery in the treatment of DPN.

Efficacy of combined application of traditional Chinese medicine foot bath and mild moxibustion in the treatment o f limb pain in diabetic peripheral neuropathy patients

Purpose: To determine the efficacy of the combination of traditional Chinese medicine (TCM) foot bath and mild moxibustion in the treatment of limb pain in patients with diabetic peripheral neuropathy (DPN).&#x0D; Methods: A total of 120 patients with symptoms of DPN-induced pain who were hospitalized at the Department of Endocrinology in the 903rd Hospital of PLA, from January 2020 to June 2021, were included in this study. They were randomly assigned to a study group and a control group, with 60 patients in each group. Patients in both groups received conventional treatments and nursing care, while those in study group were additionally treated with a combination of TCM foot bath and mild moxibustion. Treatment efficacy in the patients was evaluated using Short-Form McGill Pain Questionnaire (SF-MPQ), pain rating index (PRI), visual analogue scale (VAS), TCM symptom score (TCMSS), and Toronto Clinical Scoring System (TCSS).&#x0D; Results: Compared with control group, there were significant improvements in pain-related scores, namely, SF-MPQ, (p ˂ 0.05); PRI, (p &lt; 0.01); VAS, (p &lt; 0.05); as well as overall efficacy (p &lt; 0.05). Similar improvements were also observed with regard to TCMSS (p &lt; 0.001) and TCSS (p &lt; 0.001) in the study group. However, there were no significant changes in Adjusted Diabetes Quality of Life (A-DQOL) score and blood glucose control in both groups.&#x0D; Conclusion: Relative to the conventional treatment for DPN, limb pain and disease score of patients are significantly reduced by the combination of TCM foot bath and mild moxibustion treatments. Further clinical trials would be required prior to application in clinical practice.

Is Cerebrolysin effective in reducing symptoms of Diabetic Peripheral Neuropathy?

Aim This is an investigator initiated observational comparative medical program, to test the efficacy of Cerebrolysin® intake for 1 month versus 2 months, in patients clinically diagnosed with type 2 diabetes mellitus (T2DM) and suffering from peripheral neuropathy. Methods Patients aged ≥ 18 years old, clinically diagnosed with mild or moderate painful diabetic polyneuropathy, received Cerebrolysin® for 1 or 2 months according to investigators’ decision. Demographic data, detailed medical history, and laboratory results were collected at baseline. All enrolled patients were evaluated for Toronto Clinical Scoring System (TCSS), Visual Analogue Scale (VAS) and Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale (LANSS) at baseline and end of the program (1 month/2 month). Results VAS, TCSS, and LANSS were significantly improved for all 136 enrolled patients at the end of their treatment with Cerebrolysin® for 1 or 2 months, regarding gender, duration since diagnosis of T2DM (more than or less than 10 years) and HbA1c ≤ 9% or ˃ 9%, with a very highly statistically significant difference (p-value ˂ 0.001). They were slightly improved more in patients received Cerebrolysin® for 1 month more than for 2 months. There was no statistically significant difference for gender, duration of diagnosis with diabetes mellitus less or more than 10 years, and HbA1c ≤ 9% &amp; ˃ 9% regarding the change of VAS, TCSS, and LANSS as dependent variables, using Linear stepwise regression. While there was noticed improvement in VAS, TCSS, and LANSS with use of Cerebrolysin® for 1 month more than 2 months, Regression Coefficient (B (95% of Confidence interval)) B=0.794 (0.29-1.29), B=1.472 (0.87-2.074), B=2.143 (0.45-3.83) and p-value = 0.002, p-value ˂ 0.001, p-value = 0.13 respectively. There was no adverse event (AE) or serious adverse event (SAE) reported during the program. Conclusion: Cerebrolysin® is considered effective in the management of peripheral neuropathy in patients with T2DM Abbreviations: Adverse Event (AE), Advanced Glycation End products (AGE), Contract Research Organization (CRO), Diabetic Peripheral Neuropathy (DPN), Diacylglycerol (DAG), estimated Glomerular Filtration (eGFR), Fasting Blood Sugar (FBS), Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale (LANSS), Peripheral Vascular Disease (PVD), Pin- Prick Threshold (PPT), Protein Kinase C (PKC), Statistical Analysis Plan (SAP), Serious Adverse Event (SAE), Standard Deviation (SD), Type 1 Diabetes Mellitus (T1DM), Type 2 Diabetes Mellitus (T2DM), Toronto Clinical Scoring System (TCSS), Traumatic Brain Injury (TBI), Visual Analogue Scale (VAS).

Triple-nerve decompression surgery for the treatment of painful diabetic peripheral neuropathy in lower extremities: A study protocol for a randomized controlled trial.

Painful diabetic peripheral neuropathy (DPN) is often refractory to conventional medications. Triple-nerve decompression was proposed for painful DPN due to the frequent involvement of multiple nerve entrapments in diabetes. However, the role of decompressive surgery remains controversial. This trial aims to assess the efficacy of triple-nerve decompression for patients with painful DPN suggestive of nerve entrapment using a randomized controlled trial (RCT) design. This trial is a single-center RCT and will be conducted in Shanghai Ninth People's Hospital. Enrolled subjects (n = 74) with painful DPN due to nerve compression, which can be detected by nerve conduction studies, will be randomly allocated at a 1:1 ratio into surgical and non-surgical groups. The primary outcome will be measured by 50% responder rates, which is defined as the proportion of subjects with at least 50% reduction of the mean weekly visual analog score (VAS) of pain from baseline after 6 months of treatment. Mean weekly VAS will be additionally evaluated 1 week (W1), 1 month (M1), and 3 months (M3) after treatment to monitor the changes in pain intensity. The secondary outcomes include two-point discrimination (TPD), Toronto clinical scoring system (TCSS), electrophysiological indexes, hospital anxiety and depression scale (HADS), and the medical outcome study short-form 36-item questionnaire (SF-36). A quantitative analgesic questionnaire (QAQ) will be used as a secondary outcome to quantify the analgesic medication weekly. TPD and TCSS will be conducted at W1, M1, M3, and M6 after treatment. Electrophysiological tests, HADS, and SF-36 will be performed at M3 and M6. Ethics approval has been obtained from the Ethics Committee of Shanghai Ninth People's Hospital (SH9H-2-21-T323-2). It was registered on the Chinese Clinical Trial Registry website (http://www.chictr.org.cn) on 16 August 2021 with the number ChiCTR2100050049. Written informed consent will be obtained from all participants. The results of this trial will be disseminated via peer-reviewed journals, mass media, and presentations at national and international academic conferences.
