Role of Chinese Acupuncture in the Treatment for Chemotherapy-Induced Cognitive Impairment in Older Patients With Cancer: Protocol for a Randomized Controlled Trial. JMIR Res Protoc 2024; 13:e53853. [PMID: 38329790 PMCID: PMC10884956 DOI: 10.2196/53853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 01/06/2024] [Accepted: 01/11/2024] [Indexed: 02/09/2024] Open
Abstract
BACKGROUND Older patients with cancer experience cognitive impairment and a series of neurocognitive symptoms known as chemobrain due to chemotherapy. Moreover, older populations are disproportionately affected by chemobrain and heightened negative mental health outcomes after cytotoxic chemical drug therapy. Chinese acupuncture is an emerging therapeutic option for chemotherapy-induced cognitive impairment in older patients with cancer, despite limited supporting evidence. OBJECTIVE Our study aims to directly contribute to the existing knowledge of this novel Chinese medicine mode in older patients with cancer enrolled at the Department of Oncology/Chinese Medicine, Nanjing First Hospital, China, thereby establishing the basis for further research. METHODS This study involves a 2-arm, prospective, randomized, assessor-blinded clinical trial in older patients with cancer experiencing chemobrain-related stress and treated with Chinese acupuncture from September 30, 2023, to December 31, 2025. We will enroll 168 older patients with cancer with clinically confirmed chemobrain. These participants will be recruited through screening by oncologists for Chinese acupuncture therapy and evaluation. Electroacupuncture will be performed by a registered practitioner of Chinese medicine. The electroacupuncture intervention will take about 30 minutes every session (2 sessions per week over 8 weeks). For the experimental group, the acupuncture points are mainly on the head, limbs, and abdomen, with a total of 6 pairs of electrically charged needles on the head, while for the control group, the acupuncture points are mainly on the head and limbs, with only 1 pair of electrically charged needles on the head. RESULTS Eligible participants will be randomized to the control group or the experimental group in 1:1 ratio. The primary outcome of this intervention will be the scores of the Montreal Cognitive Assessment. The secondary outcomes, that is, attentional function and working memory will be determined by the Digit Span Test scores. The quality of life of the patients and multiple functional assessments will also be evaluated. These outcomes will be measured at 2, 4, 6, and 8 weeks after the randomization. CONCLUSIONS This efficacy trial will explore whether Chinese electroacupuncture can prevent chemobrain, alleviate the related symptoms, and improve the quality of life of older patients with cancer who are undergoing or are just going to begin chemotherapy. The safety of this electroacupuncture intervention for such patients will also be evaluated. Data from this study will be used to promote electroacupuncture application in patients undergoing chemotherapy and support the design of further real-world studies.

Abstract
Objective To observe the effect of peritumoral electroacupuncture on the induction of vascular normalization in a mouse breast cancer model. Methods A subcutaneous graft model of breast cancer was established with 4T1 breast cancer cell line in female BALB/c mice aged 6-8 weeks. The mice were randomly assigned to three groups, a tumor-bearing group (TG), peritumoral electroacupuncture tumor-bearing group (EATG), and bevacizumab tumor-bearing group (BTG), with 18 mice in each group. The TG mice did not receive any intervention, the EATG mice received peritumoral electroacupuncture for 30 minutes, and the BTG mice were intraperitoneally injected with bevacizumab at 10mg/kg. Immunofluorescence was performed to assess the expression of CD31/alpha smooth muscle actin (α-SMA) and hypoxia-inducible factor 1-alpha (HIF-1α) in the tumor tissue at various points of time, including before intervention and 3 days and 5 days after intervention. Then, 3 days after intervention, observation of morphological changes of the microvessels in the tumor tissue was performed through Hematoxylin and Eosin (HE) staining and scanning electron microscope. Results There was no significant difference in the expression of CD31, α-SMA, and HIF-1α in the tumor tissues of all groups before experimental intervention ( P>0.05). On day 3 of the experimental interventions, the CD31 and HIF-1α expression levels in the tumor tissues of the EATG and BTG mice were significantly reduced ( P<0.01), while α-SMA expression levels were significantly increased ( P<0.01) in both groups. On day 5 of the experimental interventions, the CD31 and HIF-1α expression levels in the tumor tissues of the EATG and BTG mice were still significantly lower than those in the TG mice ( P<0.01), while the α-SMA expression level was significantly higher than that in the TG group ( P<0.05). On day 3 of the experimental interventions, H&E staining showed visible microvessels in the tumor tissues of all 3 groups. In addition, scanning electron microscopic observation showed that the tumor microvessel walls of the TG mice were rough and defective, and that obvious deformities appeared in the lumen. In contrast, the walls of the microvessels of the EATG and BTG mice were generally intact and there was no obvious deformities in the lumen. Conclusion Peritumoral electroacupuncture may induce microvasculature normalization by decreasing microvascular density and increasing pericyte coverage of the neovasculature, thereby improving hypoxic microenvironment of breast cancer in mice.

Abstract
Background The purpose of this research was to assess the role of heparanase (HPSE)/syndecan1 (SDC1)/nerve growth factor (NGF) on cancer pain from melanoma. Methods The influence of HPSE on the biological function of melanoma cells and cancer pain in a mouse model was evaluated. Immunohistochemical staining was used to analyze HPSE and SDC1. HPSE, NGF, and SDC1 were detected using western blot. Inflammatory factors were detected using ELISA assay. Results HPSE promoted melanoma cell viability, proliferation, migration, invasion, and tumor growth, as well as cancer pain, while SST0001 treatment reversed the promoting effect of HPSE. HPSE up-regulated NGF, and NGF feedback promoted HPSE. High expression of NGF reversed the inhibitory effect of HPSE down-regulation on melanoma cell phenotype deterioration, including cell viability, proliferation, migration, and invasion. SST0001 down-regulated SDC1 expression. SDC1 reversed the inhibitory effect of SST0001 on cancer pain. Conclusions The results showed that HPSE promoted melanoma development and cancer pain by interacting with NGF/SDC1. It provides new insights to better understand the role of HPSE in melanoma and also provides a new direction for cancer pain treatment.

Electroacupuncture promotes apoptosis and inhibits axonogenesis by activating p75 neurotrophin receptor for triple-negative breast xenograft in mice. J Chem Neuroanat 2022; 124:102133. [PMID: 35777527 DOI: 10.1016/j.jchemneu.2022.102133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 06/26/2022] [Accepted: 06/26/2022] [Indexed: 10/17/2022]
Abstract
PURPOSE The aim of this study was to investigate the anti-tumor effect of electroacupuncture (EA) on mice bearing breast tumors by regulating p75 neurotrophin receptor (p75NTR) and remodelling intratumoral innervation. METHODS Female BALB/c mice were implanted with 4T1 breast tumor cells to establish a murine mammary cancer model. Tumor volume and weight were measured to evaluate tumor growth. Cell apoptosis was assessed by TUNEL assay. The relative expression of p75NTR, TrkA, TrkB, NGF and proNGF were detected by immunohistochemistry. Neurotransmitter and neurotrophin were detected by enzyme-linked immunosorbent assay. Intratumoral innervation was confirmed by β3-tubulin and TH labeling immunohistochemistry. The antagonist TAT-Pep5 was employed to determine if the effects of EA on tumor growth and cell apoptosis were mediated by p75NTR. RESULTS Peritumoral EA alleviated tumor growth especially after 14 days of intervention. Apoptosis index in the tumor tissue was obviously decreased after EA. Meanwhile, EA intervention significantly upregulated the expression of p75NTR and proNGF, along with a decline in the tumor growth and an increase in the cell apoptosis. Besides, EA reduced local sympathetic innervation and downregulated sympathetic neurotransmitter NE level in the local tumor. Furthermore, p75NTR antagonist alleviated EA-mediated cell apoptosis and intratumoral innervation. CONCLUSIONS One mechanism of EA intervention for alleviating tumor progression is mediated by p75NTR to promote apoptosis and decrease intratumoral axonogenesis in the tumor microenvironment.

Clinical Efficacy and Potential Mechanisms of Acupoint Stimulation Combined With Chemotherapy in Combating Cancer: A Review and Prospects. Front Oncol 2022; 12:864046. [PMID: 35547876 PMCID: PMC9082419 DOI: 10.3389/fonc.2022.864046] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Accepted: 03/23/2022] [Indexed: 11/14/2022] Open
Abstract
Although chemotherapy is the first-line treatment strategy for a variety of tumors, its side effects have limited its efficacy. This review summarizes the progress on the use of acupoint stimulation to combat chemotherapy-associated side effects, including chemotherapy-induced peripheral neuropathy (CIPN), cognitive impairment (CICI), and gastrointestinal toxicity (GI), as well as myelosuppression and immunosuppression. It was found that acupoint stimulation attenuated CIPN and GI by modulating the 5-hydroxytryptamine system in dorsal root ganglia, the dorsal horn of the spinal cord, and the duodenum by reducing oxidative stress and neuroinflammation. Acupoint stimulation also alleviated GI by activating vagal activity in the nucleus tractus solitarius and promoting the secretion of gastrointestinal neuropeptide hormones. Acupoint stimulation restored both bone marrow hematopoiesis and immune function to combat cancer. In addition, the combination of acupoint stimulation and chemotherapy could inhibit tumor growth by promoting tumor cell apoptosis and the enrichment of chemotherapeutic agents in tumor tissue and by modulating the tumor immune microenvironment and normalizing the vasculature. Multiple evidence also indicates that neuroimmune regulation may be involved in the effects of acupoint stimulation. In conclusion, the evidence suggests that acupoint stimulation can alleviate the side effects of chemotherapy and can also assist chemotherapeutic agents in inhibiting tumor growth, which expands the clinical application of acupoint stimulation in cancer treatment. However, more high-quality clinical studies are needed to confirm the clinical value of acupoint stimulation.

Abstract
Controlled ovarian hyperstimulation (COH) impairs the endometrium receptivity during the implantation window, resulting in a lower clinical pregnancy rate and a higher abortion rate. Our study explored the effect of electroacupuncture on the endometrial receptivity of COH rats. Female rats were randomly divided into normal treatment (Normal), model treatment (Model), low-frequency electroacupuncture treatment (LF-EA) and high-frequency electroacupuncture treatment (HF-EA). Rats in the Model, LF-EA, and HF-EA treatment groups were injected with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (HCG) to establish a model of COH rats. Compared with the Normal, the endometrial thickness, the number of pinopodes and amount of blastocyst implantation in the Model group were significantly reduced. Among them, the endometrial thickness and the amount of blastocyst implantation in the Model group were substantially decreased than those in the HF-EA group. High-frequency electroacupuncture treatment could markedly reduce the protein expression levels of E-cadherin, β-catenin and claudin-1 (CLDN1). During HF-EA treatment, the LIF/STAT3 signaling pathway of COH rats was enhanced. In conclusion, electroacupuncture could improve the endometrium receptivity and promote the blastocyst implantation in COH rats by reducing cell adhesion molecules and enhancing the LIF/STAT3 signaling pathway.Highlights High-frequency electroacupuncture could effectively improve endometrial receptivity and blastocyst implantation amount in COH rats.Electroacupuncture, especially high-frequency electroacupuncture, could significantly increase endometrial thickness and the number of pinopodes.High-frequency electroacupuncture significantly reduced the protein expression levels of E-cadherin, β-catenin and CLDN1 adhesion molecules in COH rats.High-frequency electroacupuncture could markedly enhance the LIF/STAT3 signaling pathway in COH rats.

Abstract
Platinum-based chemotherapy is an effective treatment used in multiple tumor treatments, but produces severe side effects including neurotoxicity, anemia, and immunosuppression, which limits its anti-tumor efficacy and increases the risk of infections. Electroacupuncture (EA) is often used to ameliorate these side effects, but its mechanism is unknown. Here, we report that EA on ST36 and SP6 prevents cisplatin-induced neurotoxicity and immunosuppression. EA induces neuroprotection, prevents pain-related neurotoxicity, preserves bone marrow (BM) hematopoiesis, and peripheral levels of leukocytes. EA activates sympathetic BM terminals to release pituitary adenylate cyclase activating polypeptide (PACAP). PACAP-receptor PAC1-antagonists abrogate the effects of EA, whereas PAC1-agonists mimic EA, prevent neurotoxicity, immunosuppression, and preserve BM hematopoiesis during cisplatin chemotherapy. Our results indicate that PAC1-agonists may provide therapeutic advantages during chemotherapy to treat patients with advanced neurotoxicity or neuropathies limiting EA efficacy.

Electroacupuncture Alleviates Inflammation of Dry Eye Diseases by Regulating the α7nAChR/NF- κB Signaling Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:6673610. [PMID: 33897942 PMCID: PMC8052151 DOI: 10.1155/2021/6673610] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Revised: 02/21/2021] [Accepted: 03/08/2021] [Indexed: 01/30/2023]
Abstract
Purpose We tried to investigate whether electroacupuncture (EA) can reduce inflammation of dry eye disease (DED) by regulating α7nAChR and inhibiting the NF-κB signaling pathway. Methods Healthy New Zealand white rabbits were treated with scopolamine hydrobromide (Scop) for 21 consecutive days to establish the DED animal model. After 21 days, EA, fluorometholone (Flu), and α7nAChR antagonist (α-BGT) treatments were performed, and the Scop injection was continued until day 35. During treatment, the fluorescence staining of the corneal epithelium and the level of tear flow were observed. The influence of EA on the LG pathology and inflammatory factors ACh, α7nAChR, and NF-κB was detected using the LG histopathology, transmission electron microscopy (TEM), cytokine protein chip technology, enzyme-linked immunosorbent assay (ELISA), and Western blot. Results The EA stimulation can reduce the corneal epithelial damage and repair epithelial cell ultrastructure, promote the tear secretion, relieve the LG atrophy and decrease lipid droplet accumulation in LG acinar cell, and reduce the levels of inflammatory cytokines (i.e., IL-1, MIP-1b, TNF-α, and IL-8) in the LG. The protective effect of EA on the inflammation and the ocular surface is similar to the corticosteroid Flu. EA and Flu can upregulate the expression of the α7nAChR and downregulate the expression of NF-κB. The α7nAChR antagonist α-BGT can reverse the protective effect of EA on the LG and the inhibitory effect on the NF-κB pathway and the expression of inflammatory factors but cannot affect the expression of Flu on the NF-κB pathway and inflammatory factors. Conclusion These results prove that EA can alleviate DEDs by stimulating the acupoints around the eyes. These beneficial effects are related to the upregulation of α7nAChR and the downregulation of NF-κB in the LG. The protective effect of LG is mediated through the anti-inflammatory pathway mediated by α7nAChR. EA can reduce the NF-κB P65 nuclear transcription and reduce inflammatory factors by regulating α7nAChR. This expression indicates that the α7nAChR/NF-κB signaling pathway may serve as a potential therapeutic target for EA to treat DEDs.

Abstract
AIMS The aim of this study was to explore the potential effect of electroacupuncture (EA) at ST36 on mice bearing breast tumors by regulating inflammatory cytokines to enhance antitumor immunity via vagus nerve. MATERIALS AND METHODS Female BALB/c mice were implanted with 4T1-luc2 breast tumor cells to establish a murine mammary cancer model. Tumor growth was evaluated by tumor volume, weight and bioluminescence imaging. Inflammatory conditions in serum and tumor tissue were assessed by cytokines (IL-1β, TNF-α and IL-10) and HE staining. Proportions and functions of CD8+ T cells, NK cells and MDSCs were identified by flow cytometry and western blot. Involvement of vagal efferent components was confirmed by ChAT and c-Fos double labeling immunohistochemistry in dorsal motor nucleus of vagus (DMV). Subdiaphragmatic vagotomy was employed to determine if the effect of EA was mediated by vagus nerve. KEY FINDINGS EA at ST36 reduced the volume and weight of tumors within 22 days after implantation. Proinflammatory cytokines IL-1β and TNF-α in serum, tumor and local inflammatory infiltration were obviously attenuated after EA. Meanwhile, EA intervention significantly augmented the proportion and cytolytic function of CD8+ T cells and NK cells, along with a decline in the accumulation and immunosuppressive activities of MDSCs. Finally, c-Fos expression in ChAT+ neurons in DMV increased following EA, and the ameliorating effect of EA was obviously blocked by subdiaphragmatic vagotomy. SIGNIFICANCE EA intervention relieved tumor progression in breast tumor-bearing mice by alleviating inflammation and enhancing antitumor immunity, which was mediated by eliciting efferent vagus nerve activity.
