Abstract
Kidney dysfunction is a prevalent complication of diabetes mellitus, contributing significantly to diabetes-related morbidity and mortality. We aim to explore whether platelet-rich plasma administration can modulate iron regulation mechanism within the kidney, thereby mitigating renal dysfunction associated with diabetes. Albino mice with an average body weight of 20 ± 5 g were randomly divided into five groups (N = 50; n = 10): Control Group, PRP Group, diabetic group (DG), treated group A (TA), and treated group B (TB). A single intraperitoneal dose of alloxan (160 mg/kg of body weight) was administered to mice in the DG and in both treated groups. Upon confirmation of diabetes, the DG was left untreated, while PRP treatment (0.5 ml/kg of body weight) was administered to the TA and TB groups for two and four weeks, respectively. Histological examinations of kidney tissues revealed notable signs of damage in DG, which were subsequently improved upon PRP treatment. Likewise, PRP treatment restored the changes in liver enzymes, oxidative stress biomarkers and serum electrolytes in both treated groups. Furthermore, there was an observed upregulation of iron regulatory genes, such as Renin, Epo, Hepc, Kim1, and Hfe, in the DG, accompanied by a downregulation of Tfr1 and Fpn; however, Dmt1 and Dcytb1 expression remained unaltered. Treatment with PRP restored the expression of iron regulatory genes in both treated groups. This study concluded that PRP treatment effectively restored the renal histochemistry and the expression of renal iron regulatory genes in an alloxan-induced diabetic mice model.

Abstract
BACKGROUND Diabetic peripheral neuropathy (DPN) is the most common complication of type 2 diabetes mellitus (T2DM); its diagnosis and treatment are based on symptomatic improvement. However, as pharmacological therapy causes multiple adverse effects, the implementation of acupunctural techniques, such as electroacupuncture (EA) has been suggested as an alternative treatment. Nonetheless, there is a lack of scientific evidence, and its mechanisms are still unclear. We present the design and methodology of a new clinical randomized trial, that investigates the effectiveness of EA for the treatment of DPN. METHODS This study is a four-armed, randomized, controlled, multicenter clinical trial (20-week intervention period, plus 12 weeks of follow-up after concluding intervention). A total of 48 T2DM patients with clinical signs and symptoms of DPN; and electrophysiological signs in the Nerve Conduction Study (NCS); will be treated by acupuncture specialists in outpatient units in Mexico City. Patients will be randomized in a 1:1 ratio to one of the following four groups: (a) short fibre DPN with EA, (b) short fibre DPN with sham EA, (c) axonal DPN with EA and (d) axonal DPN with sham EA treatment. The intervention will consist of 32 sessions, 20 min each, per patient over two cycles of intervention of 8 weeks each and a mid-term rest period of 4 weeks. The primary outcome will be NCS parameters, and secondary outcomes will include DPN-related symptoms and pain by Michigan Neuropathy Screening Instrument (MNSI), Michigan Diabetic Neuropathy Score (MDNS), Dolour Neuropatique Score (DN-4), Semmes-Westein monofilament, Numerical Rating Scale (NRS) for pain assessment, and the 36-item Short Form Health Survey (SF-36). To measure quality of life and improve oxidative stress, the inflammatory response; and genetic expression; will be analysed at the beginning and at the end of treatment. DISCUSSION This study will be conducted to compare the efficacy of EA versus sham EA combined with conventional diabetic and neuropathic treatments if needed. EA may improve NCS, neuropathic pain and symptoms, oxidative stress, inflammatory response, and genetic expression, and it could be considered a potential coadjutant treatment for the management of DPN with a possible remyelinating effect.

Abstract
Significance: This review highlights the many intracellular processes generating reactive oxygen species (ROS) in the peripheral nervous system in the context of type 1 diabetes. The major sources of superoxide and hydrogen peroxide (H2O2) are described, and scavenging systems are explained. Important roles of ROS in regulating normal redox signaling and in a disease setting, such as diabetes, contributing to oxidative stress and cellular damage are outlined. The primary focus is the role of hyperglycemia in driving elevated ROS production and oxidative stress contributing to neurodegeneration in diabetic neuropathy (within the dorsal root ganglia [DRG] and peripheral nerve). Recent Advances: Contributors to ROS production under high intracellular glucose concentration such as mitochondria and the polyol pathway are discussed. The primarily damaging impact of ROS on multiple pathways including mitochondrial function, endoplasmic reticulum (ER) stress, autophagy, and epigenetic signaling is covered. Critical Issues: There is a strong focus on mechanisms of diabetes-induced mitochondrial dysfunction and how this may drive ROS production (in particular superoxide). The mitochondrial sites of superoxide/H2O2 production via mitochondrial metabolism and aerobic respiration are reviewed. Future Directions: Areas for future development are highlighted, including the need to clarify diabetes-induced changes in autophagy and ER function in neurons and Schwann cells. In addition, more clarity is needed regarding the sources of ROS production at mitochondrial sites under high glucose concentration (and lack of insulin signaling). New areas of study should be introduced to investigate the role of ROS, nuclear lamina function, and epigenetic signaling under diabetic conditions in peripheral nerve.

Abstract
When diabetes neuropathy occurs, the oxidative stress caused by chronic hyperglycemia may result in chronic neuronal damage. To mitigate the effects of hyperglycemia-induced neuronal damage, it may be beneficial to address oxidative stress and inflammation in the body. The current study evaluated the neuroprotective efficacy of Thuja occidentalis in streptozotocin (STZ)-nicotinamide (NAD)-induced diabetic neuropathy in male Wistar rats. A single dose of STZ (65 mg/kg, i.p.) was used to induce diabetic neuropathy in Wistar rats. Serum insulin, glucose, hyperalgesia, oxidative stress, inflammatory markers, and histopathology of the sciatic nerve were evaluated for neuropathy. Wistar rats were treated with varying doses of hydroalcoholic extracts of Thuja occidentalis (HAETO) and gabapentin for 30 days. Thuja occidentalis considerably corrected the levels of inflammatory markers and oxidative stress caused by hyperglycemia; also, it led to the restoration of neuronal functions, indicating that it is effective in treating diabetic neuropathy. Furthermore, the molecular docking of thujone at the active pockets of various inflammatory mediators (IL-1β, IL-6, TGF-β1, and TNF-α) has shown good interactions with critical amino acid residues. These findings indicate that the hydroalcoholic extract of Thuja occidentalis effectively inhibits the development of diabetic neuropathy. The hypoglycemic, antioxidant, anti-hyperalgesia, and anti-inflammatory properties of Thuja occidentalis are thought to be responsible for the neuroprotective benefit.

The Protective Effect of Ethyl Acetate and n-Butanol Fractions of Wine-Steamed Ligustri Lucidi Fructus on Diabetic Nephropathy in Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:6512242. [PMID: 34745293 PMCID: PMC8566045 DOI: 10.1155/2021/6512242] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 09/22/2021] [Accepted: 10/11/2021] [Indexed: 11/18/2022]
Abstract
Ligustri Lucidi Fructus (LLF), the dry and ripe fruit of Ligustrum lucidum W. T. Aiton (Oleaceae), is a traditional Chinese medicine for nourishing the liver and kidney in clinics for thousands of years. Wine-steamed Ligustri Lucidi Fructus (WLL) can alleviate coolness and smoothness of LLF and enhance the function of nourishing the liver and kidney, so ancient and modern medicine usually used it in clinics. First of all, we prepared the extracts of different polar fractions of WLL to explore the effective fractions and potential mechanisms of WLL in the treatment of diabetic nephropathy (DN). Then, HPLC method was used to determine the contents of 12 active components in WLL and its different polar components. Finally, the potential relationship between 12 active components and physicochemical parameters of DN rats was explored. The pharmacological experiments showed that WLL, ethyl acetate (EtOAc), and n-butanol (n-BuOH) extracts not only significantly alleviated the clinical symptoms and kidney damage of DN rats but also had obvious anti-inflammatory and antioxidant effects. In addition, the results of HPLC analysis showed that the 12 active components of WLL mainly existed in the extracts of EtOAc and n-BuOH. The Pearson correlation analysis showed 12 active components and physicochemical parameters had different degrees of correlation. In conclusion, we proved that the extracts of EtOAc and n-BuOH were the effective fractions of WLL in treating DN in rats, and they could regulate the levels of inflammatory cytokines and decrease oxidation stress, which provides a basis for further research on the mechanism of WLL in treating DN and provides a pharmacological and chemical foundation for the development of new anti-DN drugs.

Abstract
Diabetic neuropathy (DN) is a late complication of diabetic mellitus and may rise into painful and painless variants. Limited studies have looked at nociceptive mechanisms of painless DN variant. The study aimed to determine phosphorylation and total NR2B subunit of N-methyl-D-aspartate receptor in the spinal cord of painless DN rat during early phase following formalin injection. Thirty-six Sprague-Dawley male rats were randomly assigned into three groups: control, painful, and painless DN (n = 12). The rats were developed into the early phase of DN for 2 weeks following diabetic induction. Two weeks later, the rats were injected with 5% formalin solution and flinching and licking responses were recorded for 60 min. The rats were sacrificed 3 days later, and the spinal cord enlargement region was collected. Immunohistochemistry and Western blot procedures were conducted to determine the phosphorylated and total NR2B subunit expressions. The results showed reduced flinching and licking responses in painless DN rats compared to control and painful DN groups, followed by a significant reduction in phosphorylated and total NR2B expression at both ipsilateral and contralateral regions of the spinal cord. In conclusion, reduced pain behavior responses in painless DN rats following formalin injection is possibly contributed by the reduced expression of phosphorylated and total NR2B subunit in the spinal cord.

Abstract
PURPOSE This study aimed to determine degree of postoperative pain and the incidence of serious postoperative pain after glaucoma surgery and further to identify the associated risk factors. METHODS A total of 194 consecutive patients who were diagnosed with glaucoma and underwent glaucoma surgery were enrolled in this study. The intensity of postoperative pain was evaluated using numerical rating scale (NRS) within 24 h after surgery; NRS ≥ 5 was considered as clinically significant postoperative pain. Risk factors associated with the development of postoperative pain were analyzed by multivariate logistic regression analysis. RESULTS Clinically significant postoperative pain was experienced at any time after glaucoma surgery in 41.75% of the patients, which peak at 2 h. 27.8% of the patients requested analgesic medication within 24 h after surgery. According to multivariate logistic regression analysis, preoperative anxiety (OR = 4.13 [1.29-13.2], p = 0.017), cyclophotocoagulation (OR = 30.9 [3.47-375.1], p = 0.002), and phacotrabeculectomy combined with or without intraocular lens implantation (OR = 30.0 [2.69-335.6], p = 0.006) were associated with increased clinically significant postoperative pain. Interestingly, patients with diabetes and/or hypertension were associated with less postoperative pain after glaucoma surgery (OR = 0.23 [0.08-0.64], p = 0.005). CONCLUSION Patients undergoing glaucoma surgery tend to experience postoperative pain in the early postoperative period. Anxiety level and surgery types of cyclophotocoagulation and phacotrabeculectomy are risk factors for postoperative pain. Patients with diabetes and/or hypertension are less likely to develop postoperative pain.

Abstract
Objective:
To investigate the relationship between Interleukin-1beta (IL-1beta) and diabetic
peripheral neuropathy (DPN) using animal models.
Materials:
The rat model of diabetic neuropathy was induced by intraperitoneal injection of a single
dose of streptozotocin (STZ) at 65mg/kg. Diabetic rats were randomly divided into two groups (10
each), one treated with 0.9% saline (DMS group) and the other with interleukin-1 receptor antagonist
(IL-1RA) at 50mg/kg (DMI group) twice a day for 5 weeks. Ten normal rats matched for weight, age
and sex served as normal controls (Con group) and were treated with saline. Morphologic studies of
sciatic nerves were achieved using light and transmission electron microscopy.
Results:
Transmission electron microscopy of the sciatic nerve showed the ultrastructure of myelin and
the axon in the IL-1RA group was highly protected compared to diabetic controls.
Conclusions:
High levels of circulating IL-1beta may be associated with the risk of DPN and anti-IL-1
treatment may provide a potential strategy for the prevention of diabetic neuropathy.

Abstract
The complications of diabetic polyneuropathy (DN) determines its level of severity. It may occur with distinctive clinical symptoms (painful DN) or appears undetected (painless DN). This study aimed to investigate microglia activation and signalling molecules brain-derived neurotrophic factor (BDNF) and downstream regulatory element antagonist modulator (DREAM) proteins in spinal cord of streptozotocin-induced diabetic neuropathy rats. Thirty male Sprague-Dawley rats (200-230 g) were randomly assigned into three groups: (1) control, (2) painful DN and (3) painless DN. The rats were induced with diabetes by single intraperitoneal injection of streptozotocin (60 mg/kg) whilst control rats received citrate buffer as a vehicle. Four weeks post-diabetic induction, the rats were induced with chronic inflammatory pain by intraplantar injection of 5% formalin and pain behaviour responses were recorded and assessed. Three days later, the rats were sacrificed and lumbar enlargement region of spinal cord was collected. The tissue was immunoreacted against OX-42 (microglia), BDNF and DREAM proteins, which was also quantified by western blotting. The results demonstrated that painful DN rats exhibited increased pain behaviour score peripherally and centrally with marked increase of spinal activated microglia, BDNF and DREAM proteins expressions compared to control group. In contrast, painless DN group demonstrated a significant reduction of pain behaviour score peripherally and centrally with significant reduction of spinal activated microglia, BDNF and DREAM proteins expressions. In conclusions, the spinal microglia activation, BDNF and DREAM proteins correlate with the pain behaviour responses between the variants of DN.

Sodium nitrate preconditioning prevents progression of the neuropathic pain in streptozotocin-induced diabetes Wistar rats. J Diabetes Metab Disord 2020; 19:105-113. [PMID: 32550160 DOI: 10.1007/s40200-019-00481-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Accepted: 12/17/2019] [Indexed: 12/14/2022]
Abstract
Purpose The purpose of the study was to evaluate the possible protective effects of low dose sodium nitrate preconditioning on the peripheral neuropathy in streptozotocin (STZ)-induced diabetic model. Methods Male Wistar rats were randomly divided into five groups: control (no intervention), control treated sodium nitrate (100 mg/L in drinking water), diabetic (no intervention), diabetic treated NPH insulin (2-4 U), and diabetic treated sodium nitrate (100 mg/L in drinking water). Diabetes was induced by intraperitoneal injection of STZ (60 mg/kg). All interventions were done for 60 days immediately following diabetes confirmation. Thermal and mechanical algesia thresholds were measured by means of hot-plate test, von Frey test, and tail-withdrawal test before the diabetic induction and after diabetes confirmation. At the end of the experiment, serum NOx level and serum insulin level were assessed. Blood glucose concentration and body weight have recorded at the base and duration of the experiment. Results Both hypoalgesia, hyperalgesia along with allodynia developed in diabetic rats. Significant alterations including, decrease in tail withdrawal latency (30th day), decreased mechanical threshold (60th day), and an increase in hot plate latency (61st day) were displayed in diabetic rats compared to control rats. Nitrate and insulin preconditioning produced protective effects against diabetes-induced peripheral neuropathy. Data analysis also showed a significant increase in glucose level as well as a considerable reduction in serum insulin and body weight of diabetic rats, which restored by both insulin and nitrate preconditioning. Conclusion Sodium nitrate preconditioning produces a protective effect in diabetic neuropathy, which may be mediated by its antihyperglycemic effects and increased serum insulin level.

Abstract
Aim: We assessed the association of monocyte count to high-density lipoprotein cholesterol ratio (MHR) with diabetic peripheral neuropathy (DPN) and its role as a marker for identification of high-risk patients for DPN. Methods: A total of 180 patients with Type II diabetes mellitus (T2DM) were enrolled in the study. MHR, erythrocyte sedimentation rate and serum CRP along with other tests for T2DM and DPN were measured. Results: Duration of T2DM (p = 0.013), insulin use (p = 0.006) and serum CRP levels (p = 0.008) were significantly higher in patients with DPN. MHR was similar between groups (p = 0.447). Duration of diabetes (OR: 1.048; p = 0.038) and the serum CRP levels (OR: 1.073; p = 0.026) were found as independent predictors for the presence of DPN, however, MHR was not. Conclusion: Higher MHR indicates an enhanced inflammation and oxidative stress which was not found to be associated with the presence of DPN.
