Efficacy and Safety of Korean Herbal Medicine for Patients with Post-Accident Syndrome, Persistent after Acute Phase: A Pragmatic Randomized Controlled Trial. Healthcare (Basel) 2023; 11:healthcare11040534. [PMID: 36833066 PMCID: PMC9957496 DOI: 10.3390/healthcare11040534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 01/31/2023] [Accepted: 02/01/2023] [Indexed: 02/15/2023] Open
Abstract
This is a pragmatic, two-armed, parallel, single-center, randomized controlled clinical trial for comparative evaluation between the effectiveness of integrated Korean medicine (IKM) and herbal medicine treatment with that of IKM monotherapy (control) for post-accident syndrome persistent after the acute phase. Participants were randomized into Herbal Medicine (HM, n = 20) and Control groups (n = 20) to receive the allocated treatment of 1-3 sessions/week for 4 weeks. Intention-to-treat analysis was conducted. The Difference of Numeric Rating Scale (NRS) change of overall post-accident syndromes from baseline to week 5 for the two groups was 1.78 (95% CI: 1.08-2.48; p < 0.001). Regarding secondary outcomes, a significant decrease compared to the baseline values was confirmed for NRS of musculoskeletal, neurological, psychiatric complaints and general symptoms of post-accident syndromes. In a survival analysis based on the recovery criteria of "patients with a reduction in the NRS of overall post-accident syndromes of ≥50%," the HM group showed a shorter time to recovery than the control group during the 17-week study period (p < 0.001 by the log-rank test). IKM combined with herbal medicine treatment significantly improved the quality of life by relieving somatic pain and alleviating the overall post-accident syndrome persistent after the acute phase; this effect was maintained for at least 17 weeks.

Abstract
Despite the progressive advances, current standards of treatments for peripheral nerve injury do not guarantee complete recovery. Thus, alternative therapeutic interventions should be considered. Complementary and alternative medicines (CAMs) are widely explored for their therapeutic value, but their potential use in peripheral nerve regeneration is underappreciated. The present systematic review, designed according to guidelines of Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols, aims to present and discuss the current literature on the neuroregenerative potential of CAMs, focusing on plants or herbs, mushrooms, decoctions, and their respective natural products. The available literature on CAMs associated with peripheral nerve regeneration published up to 2020 were retrieved from PubMed, Scopus, and Web of Science. According to current literature, the neuroregenerative potential of Achyranthes bidentata, Astragalus membranaceus, Curcuma longa, Panax ginseng, and Hericium erinaceus are the most widely studied. Various CAMs enhanced proliferation and migration of Schwann cells in vitro, primarily through activation of MAPK pathway and FGF-2 signaling, respectively. Animal studies demonstrated the ability of CAMs to promote peripheral nerve regeneration and functional recovery, which are partially associated with modulations of neurotrophic factors, pro-inflammatory cytokines, and anti-apoptotic signaling. This systematic review provides evidence for the potential use of CAMs in the management of peripheral nerve injury.

Achyranthes bidentata polypeptides promotes migration of Schwann cells via NOX4/DUOX2-dependent ROS production in rats. Neurosci Lett 2018; 696:99-107.

Abstract
Achyranthes bidentata polypeptides (ABPP), an active polypeptides isolated from the aqueous extract of Achyranthes bidentata Blume, contributes to the regeneration of injured peripheral nerves by promoting migration of Schwann cells (SCs). In this study, we aimed to investigate the possible mechanism underlying the ABPP-induced migration of primary cultured rat SCs. Transwell migration assays indicated that ABPP promoted SCs migration in a concentration-dependent manner by inducing production of NADPH-oxidase (NOX)-derived reactive oxygen species (ROS). Inhibition of ROS production by NOXs inhibitor apocynin (APO) or diphenyleneiodonium (DPI) partially blocked ABPP-mediated SCs migration. Furthermore, by using real-time polymerase chain reaction analysis and siRNA interference technique, we verified the participation of NOX subunit 4 (NOX4) and dual oxidase 2 (DUOX2) in ABPP-induced ROS production and consequential SCs migration. Taken together, these results demonstrated that ABPP promoted SCs migration via NOX4/DUOX2-activated ROS in SCs.

Abstract
We have previously shown that Achyranthes bidentata polypeptides (ABPP), isolated from Achyranthes bidentata Blume (a medicinal herb), exhibit neurotrophic and neuroprotective effects on the nervous system. To identify the major active component of ABPP, and thus optimize the use of ABPP, we used reverse-phase high performance liquid chromatography to separate ABPP. We obtained 12 fractions, among which the fraction of ABPPk demonstrated the strongest neuroactivity. Immunocytochemistry and western blot analysis showed that ABPPk promoted neurite growth in cultured dorsal root ganglion explant and dorsal root ganglion neurons, which might be associated with activation of Erk1/2. A combination of behavioral tests, electrophysiological assessment, and histomorphometric analysis indicated that ABPPk enhanced nerve regeneration and function restoration in a mouse model of crushed sciatic nerve. All the results suggest that ABPPk, as the key component of ABPP, can be used for peripheral nerve repair to yield better outcomes than ABPP.

An active component of Achyranthes bidentata polypeptides provides neuroprotection through inhibition of mitochondrial-dependent apoptotic pathway in cultured neurons and in animal models of cerebral ischemia. PLoS One 2014; 9:e109923.

Abstract
An active component has been isolated by reverse-phase high performance liquid chromatography (HPLC) from Achyranthes bidentata Blume polypeptides that are extracted from Achyranthes bidentata Blume, a Chinese medicinal herb. The active component is called ABPPk based on the order of HPLC elution. In this study, we used in vitro and in vivo experimental models of cerebral ischemia to investigate the possible neuroprotective effect of ABPPk. ABPPk treatment promoted neuronal survival and inhibited neuronal apoptosis in primary cortical neurons exposed to oxygen and glucose deprivation and in rats subjected to transient middle cerebral artery occlusion. The role of ABPPk in protection against ischemia-induced neuronal damage might be mediated by mitochondrial-dependent pathways, including modulation of apoptosis-related gene expression, regulation of mitochondrial dysfunction through restoring mitochondrial membrane potential, reducing release of mitochondrial apoptogenic factors, and inhibiting intracellular ROS production. The neuroprotective effect of ABPPk may suggest the possible use of this agent in the treatment and prevention of cerebral ischemic stroke.

Effect of Achyranthes bidentata Blume on 3T3-L1 Adipogenesis and Rats Fed with a High-Fat Diet. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2014; 2014:158018.

Abstract
The present study investigated the antiobesity effect of Achyranthes bidentata Blume root water extract in a 3T3-L1 adipocyte differentiation model and rats fed with a high-fat diet. To investigate the effect of Achyranthes bidentata Blume on adipogenesis in vitro, differentiating 3T3-L1 cells in adipocyte-induction media were treated every two days with Achyranthes bidentata Blume at various concentrations (1 to 25 μg/mL) for eight days. We found that Achyranthes bidentata Blume root inhibited 3T3-L1 adipocyte differentiation without affecting cell viability, and Western blot analysis revealed that phospho-Akt expression was markedly decreased, whereas there was no significant change in perilipin expression. Furthermore, administration of Achyranthes bidentata Blume root (0.5 g/kg body weight for six weeks) to rats fed with a high-fat diet significantly reduced body weight gain without affecting food intake, and the level of triglyceride was significantly decreased when compared to those in rats fed with only a high-fat diet. These results suggest that Achyranthes bidentata Blume root water extract could have a beneficial effect on inhibition of adipogenesis and controlling body weight in rats fed with a high-fat diet.

Abstract
Achyranthes bidentata, a Chinese medicinal herb, is reported to be neuroprotective. However, its role in cardioprotection remains largely unknown. Our present study aimed to investigate the effects of Achyranthes bidentata polypeptides (ABPP) preconditioning on myocardial ischemia/reperfusion (MI/R) injury and to test the possible mechanisms. Rats were treated with ABPP (10 mg/kg/d, i.p.) or saline once daily for one week. Afterward, all the animals were subjected to 30 min of myocardial ischemia followed by 4 h of reperfusion. ABPP preconditioning for one week significantly improved cardiac function following MI/R. Meanwhile, ABPP reduced infarct size, plasma creatine kinase (CK)/lactate dehydrogenase (LDH) activities and myocardial apoptosis at the end of reperfusion in rat hearts. Moreover, ABPP preconditioning significantly inhibited superoxide generation, gp91phox expression, malonaldialdehyde formation and enhanced superoxide dismutase activity in I/R hearts. Furthermore, ABPP treatment inhibited PTEN expression and increased Akt phosphorylation in I/R rat heart. PI3K inhibitor wortmannin blocked Akt activation, and abolished ABPP-stimulated anti-oxidant effect and cardioprotection. Our study demonstrated for the first time that ABPP reduces oxidative stress and exerts cardioprotection against MI/R injury in rats. Inhibition of PTEN and activation of Akt may contribute to the anti-oxidant capacity and cardioprotection of ABPP.

Abstract
NMDA receptor (NMDA-R) is an important molecular entity governing a wide range of functions in the central nervous system. For example, the NMDA-R is involved in memory and cognition, and impairment of both (as in Alzheimer's Disease) is attributed to NMDA-mediated neurotoxicity. With greater understanding of the NMDA-R structure, antagonists with varying degrees of binding-site and subtype selectivity have been developed and put into clinical use. Discovery of target-specific Chinese herbs have also been made in parallel. This article provides an overview of the known active sites on the NMDA-R, followed by a discussion of the relevant herbs and their constituents. Experimental evidence supporting the inhibitory role of the herbal compounds on the NMDA-R is highlighted. For some of the compounds, potential research directions are also proposed to further elucidate the underlying mechanisms of the herbs. It is envisaged that future investigations based on the present data will allow more clinically relevant herbs to be identified.

Abstract
Nerve crush injury is a well-established axonotmetic model in experimental regeneration studies to investigate the impact of various pharmacological treatments. Hericium erinaceus is a temperate mushroom but is now being cultivated in tropical Malaysia. In this study, we investigated the activity of aqueous extract of H. erinaceus fresh fruiting bodies in promoting functional recovery following an axonotmetic peroneal nerve injury in adult female Sprague-Dawley rats by daily oral administration. The aim was to investigate the possible use of this mushroom in the treatment of injured nerve. Functional recovery was assessed in behavioral experiment by walking track analysis. Peroneal functional index (PFI) was determined before surgery and after surgery as rats showed signs of recovery. Histological examinations were performed on peroneal nerve by immunofluorescence staining and neuromuscular junction by combined silver-cholinesterase stain. Analysis of PFI indicated that return of hind limb function occurred earlier in rats of aqueous extract or mecobalamin (positive control) group compared to negative control group. Regeneration of axons and reinnervation of motor endplates in extensor digitorum longus muscle in rats of aqueous extract or mecobalamin group developed better than in negative control group. These data suggest that daily oral administration of aqueous extract of H. erinaceus fresh fruiting bodies could promote the regeneration of injured rat peroneal nerve in the early stage of recovery.

Abstract
Achyranthes bidentata Blume is a commonly prescribed Chinese medicinal herb. Our previous studies have proved the neuroprotective function of Achyranthes bidentata polypeptides (ABPP), a major constituent from aqueous extracts of the herb. Now we have separated an active fraction, referred to as ABPP-E4, from ABPP by HPLC methods. This study aimed to investigate the possible therapeutic potential of ABPP-E4. Assessments of cell viability and apoptosis indicated that ABPP-E4 pretreatment, in a concentration-dependent manner, antagonized the cell viability loss and cell apoptosis of cultured SH-SY5Y cells deprived of serum. ABPP-E4 pretreatment also resulted in increase of Bcl-2/Bax ratio and inhibition of caspase-3 activation in the cells on exposure to serum deprivation. Signaling pathway analysis indicated that ABPP-E4 treatment stimulated the activation of Akt/Gsk3β signaling in cultured SH-SY5Y cells, and anti-apoptotic effects of ABPP-E4 could be blocked by chemical inhibition of PI3K. Taken together, all the results suggest that ABPP-E4 might exert protective effects against serum deprivation-induced neuronal apoptosis through modulation of PI3K/Akt/Gsk3β pathways.

Abstract
AIM OF THE STUDY GCSB-5 (traditional name: Chungpa-Juhn), an herbal medicine composed of 6 crude herbs (Saposhnikovia divaricata Schiskin, Achyranthis bidentata Blume, Acanthopanax sessiliflorum Seem, Cibotium baromets J. Smith, Glycine max Meriill, and Eucommia ulmoides Oliver), has been widely used in Asia for treatment of neuropathic and inflammatory diseases. This study investigated the protective effect of GCSB-5 against peripheral nerve injury in vitro and in vivo. MATERIALS AND METHODS After left sciatic nerve transection, rats received oral administration of GCSB-5 (30, 100, 300, and 600 mg/kg), or saline (vehicle), respectively, once daily for 8 weeks. Motor functional recovery and axonal nerve regeneration were evaluated by measurement of sciatic functional index (SFI), sensory regeneration distance, and gastrocnemius muscle mass ratio. The myelinated axon number was counted by morphometric analysis. In the in vitro study, the effects of GCSB-5 on H(2)O(2)-induced oxidative damage in SH-SY5Y cells were investigated by measurement of cell viability, production of reactive oxygen species (ROS), lipid peroxidation, release of lactate dehydrogenease (LDH), and cellular glutathione contents. Neurite outgrowth was also determined. RESULTS After 8 weeks of nerve transection, SFI, regeneration distance, and gastrocnemius muscle mass ratio and myelinated axon number showed a significant decrease and these decreases were attenuated by GCSB-5. GCSB-5 significantly inhibited H(2)O(2)-induced cell death and oxidative stress, as evidenced by decreases in production of ROS and lipid peroxidation and release of LDH, and by increase in total GSH content. CONCLUSIONS The neuroprotective effect afforded by GCSB-5 is due in part to reduced oxidative stress.

Abstract
Surgical repair of severe peripheral nerve injuries represents not only a pressing medical need, but also a great clinical challenge. Autologous nerve grafting remains a golden standard for bridging an extended gap in transected nerves. The formidable limitations related to this approach, however, have evoked the development of tissue engineered nerve grafts as a promising alternative to autologous nerve grafts. A tissue engineered nerve graft is typically constructed through a combination of a neural scaffold and a variety of cellular and molecular components. The initial and basic structure of the neural scaffold that serves to provide mechanical guidance and optimal environment for nerve regeneration was a single hollow nerve guidance conduit. Later there have been several improvements to the basic structure, especially introduction of physical fillers into the lumen of a hollow nerve guidance conduit. Up to now, a diverse array of biomaterials, either of natural or of synthetic origin, together with well-defined fabrication techniques, has been employed to prepare neural scaffolds with different structures and properties. Meanwhile different types of support cells and/or growth factors have been incorporated into the neural scaffold, producing unique biochemical effects on nerve regeneration and function restoration. This review attempts to summarize different nerve grafts used for peripheral nerve repair, to highlight various basic components of tissue engineered nerve grafts in terms of their structures, features, and nerve regeneration-promoting actions, and finally to discuss current clinical applications and future perspectives of tissue engineered nerve grafts.

Abstract
UNLABELLED We have prepared an aqueous extract of Achyranthes bidentata Blume, a Chinese medicinal herb commonly prescribed for arthritis treatment or immnopotentiation, and have found that Achyranthes bidentata extract promotes nerve growth and prevents neuronal apoptosis. AIM OF THE STUDY To investigate the protective effect of Achyranthes bidentata extract against glutamate-induced neurotoxicity in primary culture of rat hippocampal neurons. MATERIALS AND METHODS We accomplished MTT assay for cell viability, Hoechst 33342 staining, and flow cytometry for cell apoptosis analysis to examine the effects of Achyranthes bidentata extract on glutamate-induced neurotoxicity, and also used Fluo 4-AM measurement, RT-PCR and Western blot analysis to determine the changes in intracellular calcium concentration [Ca(2+)](I), and mRNA and protein levels of Bcl-2, respectively, concurrently accompanied with the influences of Achyranthes bidentata extract. RESULTS Achyranthes bidentata extract was found to inhibit glutamate-induced neuronal damage in a dose- and time-dependent manner. On the other hand, Achyranthes bidentata extract depressed glutamate-induced elevation of intracellular calcium concentration [Ca(2+)](i), and also antagonized glutamate-evoked decreases in Bcl-2 expression at mRNA and protein levels. CONCLUSION The results suggest that Achyranthes bidentata extract prevents glutamate-induced cell damage in primarily cultured hippocampal neurons by inhibiting an increase in [Ca(2+)](i), and reversing the down-regulation of Bcl-2.
