The use of transcranial direct current stimulation (tDCS) to modulate pain, psychological aspects, and cognitive functions has increased in recent years. The present scoping review aims to investigate the use of tDCS in cancer patients and its significant impact on psychocognitive and pain related symptoms. <i>Methods</i>. From the earliest available date to June 2023, a comprehensive search was conducted in three electronic scientific databases—PubMed, Scopus, and Embase—and other supplementary sources. Ten relevant studies were identified and included, comprising single case studies, randomized controlled trials, pilot studies, and one retrospective study. PRISMA guidelines for scoping reviews were followed. <i>Results</i>. These studies investigated the use of tDCS to improve pain and psychocognitive aspects in patients with various types of cancer, including breast, oral, bladder, lung, pancreatic, head and neck cancer, hepatocellular carcinoma, and meningioma. Overall, the results suggest that tDCS has shown efficacy in relieving pain, reducing anxiety and depression, and improving cognitive function in cancer patients. <i>Conclusion</i>. Due to the limited number and high heterogeneity of the existing literature in this field, more investigation and the establishment of standardized protocols would be required to obtain more conclusive evidence.","PeriodicalId":19122,"journal":{"name":"Neural Plasticity","volume":"57 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140591031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stroke is a common and frequently occurring disease among middle-aged and elderly people, with approximately 55%−75% of patients remaining with upper limb dysfunction. How to promote the recovery of motor function at an early stage is crucial to the life of the patient. <i>Objectives</i>. This study aimed to investigate whether high-definition transcranial direct current stimulation (HD-tDCS) of the primary motor cortex (M1) functional area in poststroke patients in the subacute phase is more effective in improving upper limb function than conventional tDCS. <i>Methods</i>. This randomized, sham-controlled clinical trial included 69 patients with subcortical stroke. They were randomly divided into the HD-tDCS, anodal tDCS (a-tDCS), and sham groups. Each group received 20 sessions of stimulation. The patients were assessed using the Action Research Arm Test, Fugl–Meyer score for upper extremities, Motor Function Assessment Scale, and modified Barthel index (MBI) pretreatment and posttreatment. <i>Results</i>. The intragroup comparison scores improved after 4 weeks of treatment. The HD-tDCS group showed a slightly greater, but nonsignificant improvement as compared to a-tDCS group in terms of mean change observed in function of trained items. The MBI score of the HD-tDCS group was maintained up to 8 weeks of follow-up and was higher than that in the a-tDCS group. <i>Conclusion</i>.

Numerous molecular, cellular, and anatomical factors are implicated in LBP. Current issues regarding neurologic alterations in LBP have focused on the reorganization of peripheral nerve and spinal cord, but neural mechanisms of exactly what LBP impacts on the brain required further researches. Based on existing clinical studies that chronic pain problems were accompanying alterations in brain structures and functions, researchers proposed logical conjectures that similar alterations occur in LBP patients as well. With recent extensive studies carried out using noninvasive neuroimaging technique, increasing number of abnormalities and alterations has been identified. Here, we reviewed brain alterations including white matters, grey matters, and neural circuits between brain areas, which are involved in chronic LBP. Moreover, brain structural and functional connectivity abnormalities are correlated to the happening and transition of LBP. The negative emotions related to back pain indicate possible alterations in emotional brain regions. Thus, the aim of this review is to summarize current findings on the alterations corresponding to LBP in the brain. It will not only further our understanding of etiology of LBP and understanding of negative emotions accompanying with back pain but also provide ideas and basis for new accesses to the diagnosis, treatment, and rehabilitation afterward based on integral medicine.","PeriodicalId":19122,"journal":{"name":"Neural Plasticity","volume":"68 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140151164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electroacupuncture (Ea) is a useful complementary and alternative therapy for intracerebral hemorrhage (ICH). However, the neurobiological basis for the Ea treatment of ICH is still unclear. The primary aim of the present study was to explore whether Ea prevents brain edema, apoptosis, excitotoxicity, and neuroinflammation in rats after hemorrhagic stroke. <i>Methods</i>. Rats were randomly divided into Sham, Control, and Ea groups. We used modified neurological severity score (mNSS) and gait analysis to estimate neurological function in rats, and PET/CT to assess glucose uptake and the hemorrhagic focus volume. Measurement of the brain water content and TUNEL staining were used to evaluate brain edema and cell apoptosis, respectively. The serum myelin basic protein (MBP), neuron-specific enolase (NSE), calcium-binding protein B (S100B), and tumor necrosis factor-<i>α</i> (TNF-<i>α</i>) concentrations were examined with ELISA. The expression levels of the CD68, GALC, Arg-1, iNOS, NR2A, Glu2R, AQP4, MAP2, GFAP, AQP9, Bcl-2, Bax, and Glu proteins around the hematoma were detected via immunohistochemistry staining. Western blot was used to analyze the levels of the AQP4, AQP9, Bax, Bcl-2, iNOS, and Arg-1 proteins. <i>Results</i>. Ea treatment improved neurological function and reduced the hemorrhagic area and brain water content in rats after ICH. The serum concentrations of MBP, NSE, S100B, and TNF-<i>α</i> all decreased significantly in the Ea group compared with the Control group. Expression levels of the Glu, NR2A, AQP4, AQP9, Bax, GFAP, iNOS, and CD68 proteins in brain tissue surrounding the hematoma were obviously suppressed in ICH rats following Ea treatment. Moreover, Ea stimulation increased the levels of the MAP2, GALC, Glu2R, Arg-1, and Bcl-2 proteins, but reduced the number of TUNEL-positive cells in rats after ICH. <i>Conclusion</i>.

A promising model of PS is one based on chronic exposure of pregnant rodents to variable-frequency ultrasound (US PS), as it mimics the PS with a psychic nature that most adequately captures the human stressors in modern society. The aim of this study was to investigate the effects of US PS on the brain neurotransmitter, neuropeptide, and neurotrophic systems of newborn Wistar rats. We determined the concentration of neurotransmitters and their metabolites (serotonin, HIAA, dopamine, DOPAC, and norepinephrine), neuropeptides (<i>α</i>-MSH, <i>β</i>-endorphin, neurotensin, oxytocin, and substance P), and the neurotrophin brain-derived neurotrophic factor (BDNF) in rat brain tissues by HPLC-ED, ELISA, and multiplex ELISA.
