Evaluating the effect of acupuncture on symptoms of diabetic peripheral neuropathy (DPN) among individuals with diabetic neuropathy: A single-blind, randomized trial study.

Purpose: This study aimed to investigate the impact of acupuncture on Diabetic peripheral neuropathy (DPN) symptoms among individuals with diabetic neuropathy. Methods: In a single-blind, randomized trial conducted between 2019 and 2020, 60 patients diagnosed with diabetic neuropathy were enrolled. These participants were randomly assigned to either the intervention or control group. The intervention group received real acupuncture alongside routine treatment once a week for seven sessions, each lasting 20 min. Meanwhile, the control group received sham acupuncture as an adjunct to their routine treatment, following the same schedule. To evaluate treatment efficacy, the study assessed primary outcomes, such as pain intensity measured using the Visual Analogue Scale (VAS). Secondary outcomes included evaluating fatigue severity and diabetic peripheral neuropathy (DPN) side effects, measured using the multidimensional fatigue inventory (MFI-20) and a standard questionnaire after each session. Results: No statistically significant differences in pain and fatigue scores were observed between the two groups throughout all visits, even after adjusting for baseline characteristics, age, sex, type of diabetes, discopathy, and carpal tunnel syndrome parameters (P > 0.05). The findings did not provide strong evidence supporting a significant effect of real acupuncture compared to sham acupuncture on pain and fatigue values (P = 0.267 and 0.634, respectively). However, the 95% confidence interval for pain scores (-0.35, 1.28) was inconclusive, encompassing effect sizes favoring sham acupuncture. Conclusion: Findings suggest that using acupuncture as an adjunctive therapy alongside routine treatment may not lead to a significant reduction in the symptoms of peripheral neuropathy and fatigue severity among individuals with diabetic neuropathy.

Effects of curcumin nanoparticle on the histological changes and apoptotic factors expression in testis tissue after methylphenidate administration in rats.

The present article sought to evaluate the impact of curcumin-loaded superparamagnetic iron oxide (Fe3O4) nanoparticles (NPs) on the histological variables and apoptotic agents in adult male rats after 3-weeks of methylphenidate (MPH) oral administration (20 mg/kg) versus vehicle therapy on the testis. Twenty-four male rats have been categorized randomly into four groups, in which Group 1 has been chosen as the controls, and Group 2 has been a vehicle and taken the sesame oil as curcumin carrier. Moreover, Group 3 has been taken MPH (20 mg/kg by gavage for 21 consecutive days). Group 4 received MPH plus Curcumin nanoparticles (5.4 mg/100 g) for twenty-one consecutive days. Then, testis histology, apoptosis as well as stereology have been examined. According to the examinations, curcumin nanoparticles are significantly capable of improving the sperms and stereological variables; for example, round spermatid and Leydig cells by enhancing the level of the serum testosterone in comparison with the MPH and vehicle groups. Besides, it was found that the gene expression in inflammation pathways and apoptosis genes largely diminished in the treatment group by curcumin nanoparticles in comparison with the MPH and vehicle groups, also we observed considerable differences for the weight of testes between the examined groups. Therefore, Curcumin effectively inhibited the testis damages and MPH-induced apoptosis, indicating possible protecting features of the Curcumin nanoparticles in opposition to MPH.
