Research progress of mechanism of acupuncture and moxibustion on prevention and treatment of Alzheimer's disease based on the neuronal cell cycle re-entry

Alzheimer's disease (AD) is the most common type of dementia. Studies have shown that neuronal cell cycle re-entry is an abnormal change in the early stage of AD, and it is also one of the key reasons for mediating neuronal death. The mechanism of acupuncture and moxibustion in treating AD may be related to the regulation of abnormal cell cycle. In this article, we reviewed the occurrence of AD neuronal cell cycle re-entry and its mediated cell death mechanism, listed the factors affecting neuronal cell cycle re-entry, explored the possible mechanism of acupuncture and moxibustion in preventing and treating AD by regulating AD cell cycle protein, AD neuronal cell cycle re-entry influencing factors (β-amyloid protein and Tau protein phosphorylation level, oxidative stress, brain-derived neurotrophic factor), the multi-target regulation of neuronal cell cycle re-entry, so as to provide reference for the application and research of acupuncture and moxibustion in preventing and treating AD.

Pain perception enhancement in consecutive second-eye phacoemulsification cataract surgeries under topical anesthesia.

Cataract is the main cause of visual impairment and blindness worldwide while the only effective cure for cataract is still surgery. Consecutive phacoemulsification under topical anesthesia has been the routine procedure for cataract surgery. However, patients often grumbled that they felt more painful during the second-eye surgery compared to the first-eye surgery. The intraoperative pain experience has negative influence on satisfaction and willingness for second-eye cataract surgery of patients with bilateral cataracts. Intraoperative ocular pain is a complicated process induced by the nociceptors activation in the peripheral nervous system. Immunological, neuropsychological, and pharmacological factors work together in the enhancement of intraoperative pain. Accumulating published literatures have focused on the pain enhancement during the second-eye phacoemulsification surgeries. In this review, we searched PubMed database for articles associated with pain perception differences between consecutive cataract surgeries published up to Feb. 1, 2024. We summarized the recent research progress in mechanisms and interventions for pain perception enhancement in consecutive second-eye phacoemulsification cataract surgeries. This review aimed to provide novel insights into strategies for improving patients' intraoperative experience in second-eye cataract surgeries.

Mechanism research progress of acupuncture for regulating axon regeneration after stroke.

Stroke brings the pathological changes of brain tissues such as hematoma formation or ischemia and hypoxia, which leads to neuronal death and axon degeneration. Axon regeneration after its injury is mainly dependent on the surrounding microenvironment and the related proteins, including glial scar, myelin associated inhibitory factors, axon guidance molecules, and neurotrophic factors. All of them affect axon growth by regulating the morphology and orientation of growth cones, the synaptic stability, and the proliferation and differentiation of neural stem cells. This article summarizes the mechanism of acupuncture in regulating axon regeneration after stroke. Acupuncture inhibits glial scar formation, alleviates the inhibitory effects of its physical and chemical barriers on axon growth, reverses the inhibitory effects of myelin-related inhibitory factors on axon growth, and adjusts the level of axon guidance molecules to promote the proliferation and differentiation of neural stem cells and the regeneration of injured axons, and up-regulates neurotrophic factors. Eventually, post-stroke nerve injury can be ameliorated.

Research progress in mechanism of anticancer action of shikonin targeting reactive oxygen species.

Excessive buildup of highly reactive molecules can occur due to the generation and dysregulation of reactive oxygen species (ROS) and their associated signaling pathways. ROS have a dual function in cancer development, either leading to DNA mutations that promote the growth and dissemination of cancer cells, or triggering the death of cancer cells. Cancer cells strategically balance their fate by modulating ROS levels, activating pro-cancer signaling pathways, and suppressing antioxidant defenses. Consequently, targeting ROS has emerged as a promising strategy in cancer therapy. Shikonin and its derivatives, along with related drug carriers, can impact several signaling pathways by targeting components involved with oxidative stress to induce processes such as apoptosis, necroptosis, cell cycle arrest, autophagy, as well as modulation of ferroptosis. Moreover, they can increase the responsiveness of drug-resistant cells to chemotherapy drugs, based on the specific characteristics of ROS, as well as the kind and stage of cancer. This research explores the pro-cancer and anti-cancer impacts of ROS, summarize the mechanisms and research achievements of shikonin-targeted ROS in anti-cancer effects and provide suggestions for designing further anti-tumor experiments and undertaking further experimental and practical research.

Research progress of mechanism of acupuncture for migraine.

The literature regarding the action mechanism of acupuncture for migraine published from 2013 to 2023 was searched in China National Knowledge Infrastructure (CNKI), Wanfang, VIP, Chinese Science and Technology Periodical Database, PubMed, Medline, and Cochrane Library. The pathogenesis of migraine and potential mechanisms of acupuncture treatment were summarized from the aspects of trigeminovascular system (TGVS), metabolic-related mechanisms, genetic factors, and alterations in brain structure and function. The results revealed that current research on the mechanisms of acupuncture for migraine predominantly centered around the TGVS, with studies confirming the specific regulatory effects of acupuncture on trigeminal system-related components, such as cortical spreading depression (CSD), astrocytes, and neurogenic kinin. While metabolic-related mechanisms and genetic factors are gaining attention, further in-depth exploration is needed to fully understand their roles in the mechanism of acupuncture for migraine. The study of brain structure and function in migraine has advanced, albeit with some controversies. Future research should prioritize larger sample sizes and standardized study designs to delve deeper into the mechanisms of acupuncture in treating migraine.

Research progress in mechanism of puerarin in treating vascular dementia

Vascular dementia(VD) is a condition of cognitive impairment due to acute and chronic cerebral hypoperfusion. The available therapies for VD mainly focus on mitigating cerebral ischemia, improving cognitive function, and controlling mental behavior. Achievements have been made in the basic and clinical research on the treatment of VD with traditional Chinese medicine(TCM) active components, including Ginkgo leaf extract, puerarin, epimedium, tanshinone, and ginsenoside. Most of these components have anti-inflammatory, anti-apoptotic, anti-oxidant, and neuroprotective effects, and puerarin demonstrates excellent performance in mitigating cholinergic nervous system disorders and improving synaptic plasticity. Puerarin, ginkgetin, and epimedium are all flavonoids, while tanshinone is a diterpenoid. Puerariae Lobatae Radix, pungent in nature, can induce clear Yang to reach the cerebral orifices and has the wind medicine functions of ascending, dispersing, moving, and scurrying. Puerariae Lobatae Radix entering collaterals will dredge blood vessels to promote blood flow, and that entering the sweat pore will open the mind, which is in line with the TCM pathogenesis characteristics of VD. This study reviews the progress in the mechanism of puerarin, the main active component of Puerariae Lobatae Radix, in treating VD. Puerarin can ameliorate cholinergic nervous system disorders, reduce excitotoxicity, anti-inflammation, inhibit apoptosis, alleviate oxidative stress injury, enhance synaptic plasticity, up-regulate neuroprotective factor expression, promote cerebral circulation metabolism, and mitigate Aβ injury. The pathways of action include activating nuclear factor erythroid 2-related factor 2(Nrf2)/antioxidant response element(ARE), vascular endothelial growth factor(VEGF), extracellular regulated protein kinases(ERK), phosphatidylinositol-3-kinase(PI3K)/protein kinase B(Akt), Janus-activating kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3), AMP-activated protein kinase(AMPK), as well as inhibiting the tumor necrosis factor α(TNF-α), transient receptor potential melastatin 2(TRPM2)/N-methyl-D-aspartate receptor(NMDAR), p38 mitogen-activated protein kinase(p38 MAPK), Toll-like receptor 4(TLR4)/nuclear factor-kappaB(NF-κB), early growth response 1(Egr-1), and matrix metalloproteinase 9(MMP-9). By reviewing the papers about the treatment of VD by puerarin published by CNKI, Wanfang, VIP, PubMed, and Web of Science in the last 10 years, this study aims to support the treatment and drug development for VD.

Research progress of acupuncture-moxibustion in treatment of spinal cord injury through mediating inflammatory reaction

Inflammatory reaction after spinal cord injury (SCI) is the main obstacle to the recovery of neural function. In the occurrence and development of SCI, the complex regulatory mechanisms are involved in inflammatory reaction, including the activation of inflammatory cells (e.g.macrophages and microglia), and the release of cytokines (e.g. tumor necrosis factor, interleukin and chemokines). Acupuncture-moxibustion is significantly effective in clinical treatment of SCI, and its mechanism is related to adjusting the function of inflammatory cells after SCI, modulating the expression of cytokines and the activation of NLRP3 inflammatory bodies, as well as the expression of high mobility group protein B1 and calcitonin gene related peptide. This article summarizes the research progress of mechanism of inflammatory reaction after SCI and the effects of acupuncture-moxibustion intervention in recent years so that the new ideas can be provided to clarify the pathogenesis of SCI and the effect of acupuncture-moxibustion intervention.

Research progress in mechanism of necroptosis in acute pancreatitis

Acute pancreatitis (AP) is a common and potentially threatening disease of the pancreas, and some patients eventually develop to severe acute pancreatitis (SAP). Symptomatic support therapies such as rehydration therapy and anti-infection are still the main treatments. Lacking specific therapies is the main reason for the high mortality of AP patients, especially those with SAP. Premature trypsinogen activation is the most important pathologic cellular event in the pathogenesis of AP. The release of trypsin can cause self-digestion inside and outside of acinar cells, especially the release of cathepsin B can also cause a caspase-unrelated regulatory cell death (RCD) known as necroptosis, which is closely related to the development and prognosis of AP. Therefore, it is necessary to further study the mechanism of necroptosis in the occurrence and development of AP. This article reviews the mechanism of necroptosis and the research progress related to AP, in an attempt to provide a new understanding of the pathogenesis and treatment of AP, and promote the better target drug development.
