Abstract
As global warming progresses, heat waves are becoming increasingly frequent and intense, meanwhile the incidence of heat stroke (HS) has increased sharply during the past decades. HS is typically associated with significant morbidity and mortality, and there is an urgent need for further research to solve this difficult issue. There currently exists difficulties regarding on-site emergency treatment methods and limited in-hospital treatment approaches, and better treatments are required as soon as possible. Theories and therapies from various traditional Chinese medicine (TCM) academic groups have been widely reported. Therefore, an exploration of prevention and protection methods should consider TCM experiences as an alternative. This article primarily reviews TCM herbal therapies and external therapies that have been described in various clinical reports and demonstrated in relevant studies. Herbal therapies, including herbal formulas, Chinese patent medicines (CPMs), single Chinese herbs, and associated extracts or monomers, are summarized based on the shared perspectives of the underlying mechanisms from TCM. In addition, external therapies including acupuncture, bloodletting, cupping, Gua sha and Tui na that have rarely been rarely mentioned and considered in most cases, are introduced and discussed to offer a unique perspective in the search for novel interventions for HS. In summary, TCM may provide abundant potential clinical benefits and research directions in the fight against HS.

Front Pharmacol 2023; 14:1047650. [PMID: 36843924 PMCID: PMC9947652 DOI: 10.3389/fphar.2023.1047650] [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: 09/18/2022] [Accepted: 01/23/2023] [Indexed: 02/11/2023] Open
Abstract
Objective: The aim of this study is to critically appraise whether published systematic reviews/meta-analyses of traditional Chinese medicine for adults with ischemic stroke are of sufficient quality and to rate the quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation approach. Method: A literature search was performed in the Cochrane Library, PubMed, Chinese National Knowledge Infrastructure, and SinoMed databases by March 2022. The inclusion criteria were systematic reviews/meta-analyses of traditional Chinese medicine in adults who suffered from ischemic stroke. A Measurement Tool to Access Systematic Reviews 2 (AMSTAR-2) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Abstract (PRISMA-A) statements were used to assess the methodological and reporting quality of the included reviews. The Grading of Recommendations, Assessment, Development, and Evaluation system was utilized to assess each report's evidence level. Results: Of the 1,908 titles and abstracts, 83 reviews met the inclusion criteria. These studies were published between 2005 and 2022. The results of AMSTAR-2 showed that 51.4% of the items were reported, but the registration, reasons for the inclusion of study design, the list of excluded studies, and funding information were ignored in the majority of the reviews. The results of PRISMA-A showed that 33.9% of items were reported, and the information on registration, limitation, and funding was not available in many publications. The assessment of the evidence with the Grading of Recommendations, Assessment, Development, and Evaluation showed that more than half (52/83) of the included studies had either low or very low levels of evidence. Conclusion: The reporting quality in the abstract of systematic reviews/meta-analyses on traditional Chinese medicine for ischemic stroke is poor and does not facilitate timely access to valid information for clinical practitioners. Although the methodological quality is of a medium level, this evidence lacks certainty, especially with a high risk of bias in individual studies.

Sheng Mai San ameliorated heat stress-induced liver injury via regulating energy metabolism and AMPK/Drp1-dependent autophagy process. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 97:153920. [PMID: 35026620 DOI: 10.1016/j.phymed.2021.153920] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 12/21/2021] [Accepted: 12/30/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND Liver damage is one of the most common complications in humans and animals after heat stress (HS). Sheng Mai San (SMS), a traditional Chinese medicine prescription that originated in the Jin Dynasty, exert a therapeutic effect on HS. However, how SMS prevents liver injury after heat exposure remains unknown. PURPOSE This study aimed to investigate the pharmacological effect and molecular mechanisms of SMS on HS-induced liver injury. STUDY DESIGN A comprehensive strategy via incorporating pharmacodynamics, targeted metabolomics, and molecular biology technology was adopted to investigate energy metabolism changes and the therapeutic mechanisms of SMS in HS-induced rat liver injury. METHODS First, Sprague-Dawley rats were subjected to HS (38 °C/ 75% RH/ 2 h/ day) for 7 consecutive days to establish the HS model, and SMS was given orally for treatment 2 h before heat exposure. Thereafter, liver function and pathological changes in liver tissue were evaluated. Finally, the underlying mechanisms of SMS were determined using targeted energy metabolomics to comprehensively analyze the metabolic pathways and were further verified through Western-blot and qRT-PCR assays. RESULTS Our results showed that SMS alleviated HS-induced liver dysfunction by reducing the alanine aminotransferase (ALT), aspartate aminotransferase (AST), and AST/ALT ratios in serum and improving hepatic pathological damage. Meanwhile, SMS suppressed inflammatory response, oxidative injury, and overexpression of heat shock proteins in liver tissue after heat exposure. With the help of targeted energy metabolomics, we found that SMS could effectively regulate glycolysis and tricarboxylic acid (TCA) cycle to relieve energy metabolism disorder. Furthermore, we confirmed that SMS can facilitate the phosphorylation of AMP-activated protein kinase (AMPK) to maintain mitochondrial homeostasis through a dynamin protein 1 (Drp1)-dependent mitophagy process. CONCLUSION On the basis of energy metabolomics, the present study for the first time systematically illustrated the protective effect of SMS on HS-induced liver injury, and preliminarily confirmed that an AMPK-mediated Drp1-dependent mitophagy and mitochondria rebuilding process plays an important role in SMS intervention on HS-induced rat liver. Together, our study lends further support to the use of SMS in treating HS condition.

Abstract
Accumulating evidences have proved the protective role of traditional Chinese medicine in improving neurological damage induced by cerebral hypoxia-ischemia. Herein, we hypothesized that Dendrobium officinale aqueous extract exerted neuroprotection against brain damage. Initially, a model of hypoxic-ischemic brain damage (HIBD) was induced in neonatal rats, which were subsequently intragastrically administered with different doses of Dendrobium officinale aqueous extract. Next, the antioxidant capacity was examined by enzyme-linked immunosorbent assay. 2,3,5-Triphenyltetrazolium chloride and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling staining assays were adopted to determine neuronal apoptosis in brain tissues. Furthermore, neurotrophic factors and hypoxia-inducible factor-1α (HIF-1α) expression was identified by Western blot analysis. The neonatal rat models of HIBD presented impaired neurobehaviors and antioxidant capacity, increased neuronal apoptosis and expression of HIF-1α and histone deacetylase 1 (HDAC1), as well as diminished expression of neurotrophic factors and K+ -Cl- -cotransporter 2 (KCC2). Notably, in response to different doses of Dendrobium officinale aqueous extract, the impairment on neurobehaviors and antioxidant capacity was alleviated, accompanied by reduced levels of nitric oxide synthase, nitric oxide, and malondialdehyde, and increased superoxide dismutase activity. Besides, the neuronal apoptosis was inhibited as reflected by down-regulated cleaved caspase-3 and Bax and up-regulated Bcl-2. Moreover, we also found accelerated expression of neurotrophic factors and KCC2 and diminished expression of HIF-1α and HDAC1. Altogether, this present study highlights that the aqueous extract of Dendrobium officinale can suppress the neuronal apoptosis and enhance the expression of neurotrophic factors to protect neonatal rats against HIBD.

Shengmai injection alleviates H 2O 2‑induced oxidative stress through activation of AKT and inhibition of ERK pathways in neonatal rat cardiomyocytes. JOURNAL OF ETHNOPHARMACOLOGY 2019; 239:111677. [PMID: 30615921 DOI: 10.1016/j.jep.2019.01.001] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/08/2018] [Revised: 12/07/2018] [Accepted: 01/02/2019] [Indexed: 06/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Shengmai injection (SMI) is a classical traditional Chinese medicine (TCM) officially recorded in Pharmacopoeia of the People's Republic of China (version 2015) and has long been used to treat heart failure in China. However scientific evidence for the anti-oxidative stress potential of SMI used in traditional medicine is lacking. AIM OF STUDY The present study aimed to evaluate the efficacy of SMI in alleviating H2O2‑induced Oxidative Stress the underlying mechanisms MATERIALS AND METHODS: H2O2-induced oxidative stress model of cardiomyocytes was established with primary cultured neonatal rat cardiomyocytes. CCK8 cell viability assay and lacatate dehydrogenase cytotoxicity assay were performed to ensure the safety dose and lowest effective dose for the mode employing CCK-8 cell viability assay kit and lactate dehydrogenase cytotoxicity assay kit. ROS levels were determined using CM-H2DCFDA fluorescent probe in cardiomyocytes with H2O2-induced oxidative stress. The change of NAD(P)H level in cardiomyocytes was evaluated during the process of oxidative stress. The content of myocardial cytosolic Ca2+ and Ca2+ was determined using Fura-2/AM and Rhod 2-AM fluorescent probe in mitochondrial in the process of oxidative stress. Annexin V-FITC/PI double staining was applied to examine the apoptotic cells in cardiomyocytes with oxidative stress. To identify the apoptosis after oxidative stress myocardial cells with the application of Annexin V-FITC/PI double staining apoptosis detection kit. Quantitative polymerase chain reaction (RT-PCR) was applied to measure the expression of antioxidant enzymes: catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GSR). Western blot was performed to observe the phosphorylation of AKT and ERK1/2. RESULTS SMI was shown to significantly attenuate oxidative stress-induced cell proliferation arrest and apoptosis in neonatal rat cardiomyocytes. In addition, SMI treatment could decrease the production of reactive oxygen species (ROS), nicotinamide adenine dinucleotide (NADH) and malondialdehyde (MDA), and reduce the overloads of cytoplasmic Ca2+ and mitochondrial Ca2+ induced by H2O2. SMI could also restore the mRNA expression and activities of SOD, GSR, and CAT suppressed by H2O2. Mechanistically, SMI upregulated intracellular AKT phosphorylation and downregulate ERK1/2 phosphorylation in H2O2-treated cardiomyocytes. Pretreatment with LY294002, an AKT phosphorylation inhibitor, suppressed the protective role of SMI in cardiomyocytes, while pretreatment with PD98059, an ERK1/2 phosphorylation inhibitor, enhanced the effect of SMI. CONCLUSIONS In conclusion, SMI may attenuate oxidative stress-induced damage in cardiomyocytes potentially through the AKT and ERK1/2 pathway and can function as a promising injectable traditional Chinese medicine to treat oxidative stress-induced injury.

Abstract
Alternative medicines attract attention because stroke is rarely expected to make a full recovery with the most advanced medical technology. Angelica gigas (AG) is a well-known herbal medicine as a neuroprotective agent. The present study introduced mesenchymal stem cells (MSCs) to identify for the advanced treatment of the cerebrovascular disease. The objective of this research is validation of the enhanced effects of multiple combined treatment of AG extract with MSCs on stroke through angiogenesis. Our results confirmed that AG extract with MSCs improved the neovascularization increasing expression of angiogenesis-regulated molecules. The changes of brain and the behavioral ability showed the increased effects of AG extract with MSCs. As a result, AG extract and MSCs may synergistically increase the therapeutic potential by enhancing neovascularization. This mixed approach provides a new experimental protocol of herbal medicine therapy for the treatment of a variety of diseases including stroke, trauma, and spinal cord injury.

Abstract
BACKGROUND Shengmai San (SMS), a Chinese classic herbal formula, has been widely used for the treatment of Qi-Yin deficiency syndrome in Asia. Modern pharmacological studies have shown that SMS improves the cognitive function. However, the quality markers (Q-markers) for SMS still need further research. PURPOSE Using chinmedocmics strategy to systematically evaluate the efficacy of SMS in the treatment of APPswe/PS1dE9 (APP/PS1) transgenic model of Alzheimer's disease (AD) and to discover the efficacy-related Q-markers. METHODS The effect of SMS on APP/PS1 mice was evaluated by behavioral test, immunohistochemistry and urine metabolic profile, and the urine marker metabolites associated with SMS treatment of AD were characterized using metabolomics method. In the premise of efficacy, Serum Pharmacochemistry of Traditional Chinese Medicine was applied to investigate the in vivo constituents of SMS. A correlation analysis between marker metabolites of therapeutic effects and serum constituents was completed by chinmedomics approach. RESULTS SMS had a therapeutic effect on APP/PS1 mice, and 34 potential urine biomarkers were reversed by SMS treatment. A total of 17 in vivo constituents were detected, including 14 prototype components and 3 metabolites. The correlation analysis showed that eight constituents were extremely correlated with protective effects of SMS in AD, and considered as potential Q-markers of SMS, including schisandrin, isoschisandrin, angeloylgomisin Q, gomisin D, angeloylgomisin H, gomisin M2, ginsenoside F1, 20(R)-ginsenoside Rg3. CONCLUSION This study has demonstrated that chinmedomics is novel strategy for discovering the potential effective constituents from herbal formula, which are recognized as Q-markers.

Abstract
OBJECTIVE Patients with cardiac arrhythmia were more likely to develop stroke than general population. The therapeutic effect of traditional Chinese medicine (TCM) on the risk of stroke in patients with cardiac arrhythmia was unknown. The aim of this study is to investigate the risk of stroke in patients with cardiac arrhythmia receiving TCM. METHODS From the one million cohort of the Taiwan's National Health Insurance Research Database, we identified cohort of cardiac arrhythmia included 2029 patients who received TCM treatment in 2000-2004. The matching methods with propensity score was used to select 2029 appropriate control cohort for comparison. Incident events of stroke were identified during the follow-up period at the end of 2010. Cox proportional hazard model was used to calculate adjusted hazard ratios and 95% confidence intervals of stroke associated with TCM treatment. RESULTS During the follow-up period, patients with cardiac arrhythmia who underwent TCM treatment (11.4 per 1000 person-years) had a lower incidence of new-onset stroke than those without TCM treatment (17.7 per 1000 person-years), with an HR of 0.62 (95% CI=0.50-0.78). The association between TCM treatment and decreased new-onset stroke was both significant in women and men. The young patients aged 45-54 years who received TCM had the lowest risk of stroke (HR=0.48, 95% CI=0.27-0.87). CONCLUSIONS Receiving TCM treatment was associated with a lower risk of stroke in patients with cardiac arrhythmia. However, this study was limited by lack of information regarding lifestyles, biochemical profiles, the dose of herbal medicine, and acupuncture points used in treatments.

Ma R, Sun L, Chen X, Mei B, Chang G, Wang M, Zhao D. Proteomic Analyses Provide Novel Insights into Plant Growth and Ginsenoside Biosynthesis in Forest Cultivated Panax ginseng (F. Ginseng). FRONTIERS IN PLANT SCIENCE 2016; 7:1. [PMID: 26858731 PMCID: PMC4726751 DOI: 10.3389/fpls.2016.00001] [Citation(s) in RCA: 91] [Impact Index Per Article: 11.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/16/2016] [Accepted: 01/05/2016] [Indexed: 05/18/2023]
Abstract
F. Ginseng (Panax ginseng) is planted in the forest to enhance the natural ginseng resources, which have an immense medicinal and economic value. The morphology of the cultivated plants becomes similar to that of wild growing ginseng (W. Ginseng) over the years. So far, there have been no studies highlighting the physiological or functional changes in F. Ginseng and its wild counterparts. In the present study, we used proteomic technologies (2DE and iTRAQ) coupled to mass spectrometry to compare W. Ginseng and F. Ginseng at various growth stages. Hierarchical cluster analysis based on protein abundance revealed that the protein expression profile of 25-year-old F. Ginseng was more like W. Ginseng than less 20-year-old F. Ginseng. We identified 192 differentially expressed protein spots in F. Ginseng. These protein spots increased with increase in growth years of F. Ginseng and were associated with proteins involved in energy metabolism, ginsenosides biosynthesis, and stress response. The mRNA, physiological, and metabolic analysis showed that the external morphology, protein expression profile, and ginsenoside synthesis ability of the F. Ginseng increased just like that of W. Ginseng with the increase in age. Our study represents the first characterization of the proteome of F. Ginseng during development and provides new insights into the metabolism and accumulation of ginsenosides.

Abstract
SMXZF is a combination of Rb1, Rg1, schizandrin, and DT-13 (6:9:5:4) derived from Sheng-mai San, a widely used Chinese traditional medicine for the treatment of cardiovascular and cerebral diseases. The present study explores the inhibitory effects and signaling pathways of SMXZF on autophagy induced by cerebral ischemia-reperfusion injury. Male C57BL/6 mice were subjected to ischemia-reperfusion insult by right middle cerebral artery occlusion (MCAO) for 1 hr with subsequent 24 hr reperfusion. Three doses of SMXZF (4.5, 9, and 18 mg/kg) were administered intraperitoneally (i.p.) after ischemia for 1 hr. An autophagic inhibitor, 3-methyladenine (3-MA; 300 μg/kg), was administered i.p. 20 min before ischemia as a positive drug. We found that SMXZF significantly increased cerebral blood flow and reduced the infarct volume, brain water content, and the neurological deficits in a dose-dependent manner. Similar to the positive control, SMXZF at 18 mg/kg also significantly inhibited autophagosome formation. Immunofluorescence staining and Western blotting demonstrated that SMXZF could significantly decrease the expression levels of beclin1 and microtubule-associated protein 1 light chain 3. SMXZF also remarkably inhibited the phosphorylation of adenosine monophosphate-activated protein kinase (AMPK) and mammalian target of rapamycin (mTOR) as well as the expression of c-Jun N-terminal kinase (JNK) and its phosphorylation induced by 24 hr reperfusion. Finally, we demonstrated that the optimal administration time of SMXZF was at the early period of reperfusion. This study reveals that SMXZF displays neuroprotective effect against focal ischemia-reperfusion injury, possibly associated with autophagy inactivation through AMPK/mTOR and JNK pathways.

Abstract
The hypothalamus may be involved in regulating homeostasis, motivation, and emotional behavior by controlling autonomic and endocrine activity. The hypothalamus communicates input from the thalamus to the pituitary gland, reticular activating substance, limbic system, and neocortex. This allows the output of pituitary hormones to respond to changes in autonomic nervous system activity. Environmental heat stress increases cutaneous blood flow and metabolism, and progressively decreases splanchnic blood flow. Severe heat exposure also decreases mean arterial pressure (MAP), increases intracranial pressure (ICP), and decreases cerebral perfusion pressure (CPP = MAP - ICP), all of which lead to cerebral ischemia and hypoxia. Compared with normothermic controls, rodents with heatstroke have higher hypothalamic values of cellular ischemia (e.g., glutamate and lactate-to-pyruvate ratio) and damage (e.g., glycerol) markers, pro-oxidant enzymes (e.g., lipid peroxidation and glutathione oxidation), proinflammatory cytokines (e.g., interleukin-1β and tumor necrosis factor-α), inducible nitric oxide synthase-dependent nitric oxide, and an indicator for the accumulation of polymorphonuclear leukocytes (e.g., myeloperoxidase activity), as well as neuronal damage (e.g., apoptosis, necrosis, and autophagy) after heatstroke. Hypothalamic values of antioxidant defenses (e.g., glutathione peroxidase and glutathione reductase), however, are lower. The ischemic, hypoxic, and oxidative damage to the hypothalamus during heatstroke may cause multiple organ dysfunction or failure through hypothalamic-pituitary-adrenal axis mechanisms. Finding the link between the signaling and heatstroke-induced hypothalamic oxidative and ischemic damage might allow us to clinically attenuate heatstroke. In particular, free radical scavengers, heat shock protein-70 inducers, hypervolemic hemodilution, inducible nitric oxide synthase inhibitors, progenitor stem cells, flutamide, estrogen, interleukin-1 receptor antagonists, glucocorticoid, activated protein C, and baicalin mitigate preclinical heatstroke levels.

Abstract
Panax ginseng Meyer has been widely used as a tonic in traditional Korean, Chinese, and Japanese herbal medicines and in Western herbal preparations for thousands of years. In the past, ginseng was very rare and was considered to have mysterious powers. Today, the efficacy of drugs must be tested through well-designed clinical trials or meta-analyses, and ginseng is no exception. In the present review, we discuss the functions of ginseng described in historical documents and describe how these functions are taken into account in herbal prescriptions. We also discuss the findings of experimental pharmacological research on the functions of ginseng in ginseng-containing prescriptions and how these prescriptions have been applied in modern therapeutic interventions. The present review on the functions of ginseng in traditional prescriptions helps to demystify ginseng and, as a result, may contribute to expanding the use of ginseng or ginseng-containing prescriptions.

Abstract
BACKGROUND Complementary and alternative medicine (CAM) is commonly used by persons with stroke throughout the world, particularly in Asia. OBJECTIVE The objectives of this study were to determine the frequency of CAM use and the factors that predict the use of CAM in stroke patients. METHODS This study was carried out in the stroke units of Christian Medical College, Ludhiana, and Sree Chitra Tirunal Institute for Medical Sciences and Technology, Thiruvananthapuram, India, from June 2010 to December 2010. Participants were interviewed using a structured questionnaire (≥ 6 months post stroke). Outcomes were assessed using a modified Rankin Scale (mRS). RESULTS Three hundred fourteen stroke patients were interviewed; mean age was 57.4 ± 12.9 years, and 230 (73.2%) patients were men. Of 314 patients, 114 (36.3%) had used the following CAM treatments: ayurvedic massage, 67 (59.3%); intravenous fluids, 22 (19.5%); herbal medicines, 17 (15%); homeopathy, 15 (13.3%); witchcraft, 3 (2.7%); acupuncture, 3 (2.7%); opium intake, 10 (8.8%); and other nonconventional treatments, 10 (8.8%). Patients with severe stroke (P < .0001), limb weakness (P < .0001), dysphagia (P = .02), dyslipidemia (P = .007), hypertension (P = .03), or hemorrhagic stroke (P<.0001) and patients with poor outcome (mRS >2;P < .0001) often used CAM treatments. CONCLUSION More than one-third of the patients in this study opted for CAM. Presence of limb weakness, dysphagia, dyslipidemia, hypertension, hemorrhagic stroke, severe stroke, and poor outcome predicted the use of CAM.

Abstract
Background Several methodological issues with non-randomized comparative clinical studies have been raised, one of which is whether the methods used can adequately identify uncertainties that evolve dynamically with time in real-world systems. The objective of this study is to compare the effectiveness of different combinations of Traditional Chinese Medicine (TCM) treatments and combinations of TCM and Western medicine interventions in patients with acute ischemic stroke (AIS) by using Markov decision process (MDP) theory. MDP theory appears to be a promising new method for use in comparative effectiveness research. Methods The electronic health records (EHR) of patients with AIS hospitalized at the 2nd Affiliated Hospital of Guangzhou University of Chinese Medicine between May 2005 and July 2008 were collected. Each record was portioned into two "state-action-reward" stages divided by three time points: the first, third, and last day of hospital stay. We used the well-developed optimality technique in MDP theory with the finite horizon criterion to make the dynamic comparison of different treatment combinations. Results A total of 1504 records with a primary diagnosis of AIS were identified. Only states with more than 10 (including 10) patients' information were included, which gave 960 records to be enrolled in the MDP model. Optimal combinations were obtained for 30 types of patient condition. Conclusion MDP theory makes it possible to dynamically compare the effectiveness of different combinations of treatments. However, the optimal interventions obtained by the MDP theory here require further validation in clinical practice. Further exploratory studies with MDP theory in other areas in which complex interventions are common would be worthwhile.

Abstract
An ultra-performance liquid chromatography-high definition mass spectrometry (UPLC-HDMS) method was developed for detection and characterization of the chemical constituents in ShengMai San (SMS), a traditional Chinese medical formula (TCMF). The full-scan LC-MS/MS data sets combined with extra mass were acquired within 14 min using UPLC-HDMS in the MS(E) mode in a single injection. As a result, 92 compounds were identified by comparing the accurate mass and fragments information with that of the authentic standards as well as by MS analysis and the correlative references data. These constituents included ginsenosides, lignans, steroidal saponins and homoisoflavanones. Among them, 25-hydroxyginsenosides were discovered in SMS for the first time. Compare with the previous studies, our research detected more compounds and presented more rapid by applying UPLC-HDMS. It is concluded that a rapid and effective method has been established based on UPLC-HDMS with the utilization of MS(E) , which shows high sensitivity and resolution that is suitable for identifying the constituents of SMS, and this method could be applied to other TCMF.

Abstract
Objective: The present study was carried out to evaluate the neuroprotective effect of the aqueous extract of Embelia ribes, in focal ischemic brain. Materials and Methods: Adult male Wistar albino rats were fed with the aqueous extract of Embelia ribes (100 and 200 mg/kg, p.o.) for 30 days. After 30 days of feeding, all the animals were anaesthetized with chloral hydrate (400 mg/kg, i.p.). The right middle cerebral artery was occluded with a 4-0 suture for 2 h. The suture was removed after 2 h, to allow reperfusion injury. The animals were used for grip strength measurement, biochemical estimation in serum and brain tissue (hippocampus and frontal cortex) and cerebral infarct size measurement. Results: In the ischemic group, a significant (P < 0.01) alteration in the markers of oxidative damage (thiobarbituric acid reactive substances (TBARS); reduced glutathione (GSH); glutathione peroxidase (GPx); glutathione reductase (GR); and, glutathione-S-transferase (GST)) was observed in the hippocampus and frontal cortex, as compared to sham operated rats. We observed that the animals treated with the aqueous extract of Embelia ribes had a significant (P < 0.01) increase in the poststroke grip strength activity. Further, supplementation with aqueous extract of Embelia ribes reversed the levels/activities of the above mentioned biochemical parameters significantly (P< 0.01) and also resulted in decreased cerebral infarct area, as compared to the ischemic group. Conclusion: The results of our study, for the first time, provide clear evidence that aqueous extract of Embelia ribes pretreatment ameliorates cerebral ischemia/reperfusion injury and enhances the antioxidant defense against middle cerebral artery occlusion-induced cerebral infarction in rats; it exhibits neuroprotective property.

Abstract
Background Yiqifumai is a traditional Chinese medicine compound preparation used for treatment of microcirculatory disturbance-related diseases in China. We have previous reported that pretreatment with Yiqifumai could improve the lipopolysaccharide (LPS) -induced microcirculatory disturbance in rat mesentery. The present study intended to investigate the effect of pretreatment with Yiqifumai on intestine injury and survival rate of the rats subjected to LPS challenge. Methods Male Wistar rats were continuously infused with LPS (5 mg kg-1 body weight h-1) via the left jugular vein for 90 min. In some rats, Yiqifumai 80 (mg/kg) was administrated through the left jugular vein 10 min before LPS infusion. The mean arterial pressure (MAP), heart rate (HR), rectal temperature (RT), respiratory rate (RR) and survival rate were measured at 24 h, 48 h and 72 h after LPS infusion. At 72 h after exposure to LPS, the intestine morphology was observed under a stereomicroscope and the immunohistochemistry staining of intestine was conducted to evaluate the expression of intercellular adhesion molecule 1 (ICAM-1) and the number of myeloperoxidase (MPO) positive cells in tissue. After observation of intestine microcirculation, blood was collected from the abdominal aorta of each animal to analyze the level of inflammatory markers in plasma, including TNF-α and MCP-1. Results Compared to the control, LPS infusion significantly decreased MAP and the survival rate and increased the HR, RT and RR, as well as elicited leukocyte infiltration, intestine hemorrhage, enhanced expression of ICAM-1 and raised level of inflammatory markers. All of indicators, except for the RT, were significantly attenuated by Yiqifumai, in contrast to the LPS group. Conclusions The results demonstrated the potential of pretreatment with Yiqifumai to ameliorate rat intestine injury, inflammatory response to LPS and the decrease in survival rate caused by LPS challenge.

Abstract
Wei Kang Su (WKS) is an antioxidant-enriched herbal product manufactured on the basis of Shengmai San, a well-known traditional Chinese herbal formula. In the present study, we investigated the effects of WKS co-treatment on chronic ethanol toxicity in rats. WKS co-treatment protected against chronic ethanol-induced hepatotoxicity, as evidenced by the suppression of plasma enzyme activities and reactive oxygen metabolite levels, as well as the inhibition of hepatic mitochondrial malondialdehyde production in chronic ethanol-intoxicated rats. The hepatoprotection afforded by WKS co-treatment in chronic ethanol-intoxicated rats was associated with a reversal of altered hepatic mitochondrial antioxidant status and adenosine triphosphate (ATP) generation capacity, as well as heat shock protein 25/70 production. Therefore, WKS may offer the prospect of preventing ethanol-associated liver damage by increasing the resistance of mitochondria to oxidative stress.

Abstract
A 71-year-old man was stable on warfarin (2.25 mg daily) therapy with an international normalized ratio (INR) of 1.8-2.2 after a heart valve replacement surgery. Recently, he consumed the liquid-like herbal product called shengmai-yin (10 mL daily) against medical advice. Seven days after the daily consumption of shengmai-yin, he was admitted to the intensive care unit because of consciousness disturbance [Glasgow Coma Scale (GCS) score 7] with an INR of 5.08. Head computed topography revealed intracerebral hematoma in the left temporoparietal region. Both warfarin therapy and the herbal product were withdrawn. At the same time, therapy with intravenous vitamin K1 40 mg was started. On the second day of admission, craniectomy was performed to remove the intacerebral hematoma under general anesthesia. He remained confused and restless for 2 days, but then showed progressive recovery in the consciousness level as well as motor and verbal functions. Shengmai-yin contains herbal ingredients that can interact with warfarin. The Drug Interaction Probability Scale (DIPS) indicated that warfarin and shengmai-yin were highly probable causes of intracerebral hematoma. Patients on warfarin therapy should be discouraged from taking herbal medicines, especially preparations that are already known to have antiplatelet and antithrombotic effects.

ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2009; 28:248-253. [PMID: 21784011 DOI: 10.1016/j.etap.2009.04.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/27/2009] [Revised: 04/17/2009] [Accepted: 04/23/2009] [Indexed: 05/31/2023]
Abstract
GGA (geranylgeranylacetone) may induce Hsp70 synthesis, thus contributing to the protective effects of GGA in several disease states. This study evaluated the protective effects of GGA against heat injury to rat and striatum neurons in terms of mechanisms. Rats were exposed to 41.5°C for 35 min to induce heatstroke; the protective effects of GGA were then evaluated by change in rectal temperature (Tre) during heat exposure and survival time after heatstroke. Primary cultured striatum neurons were incubated with GGA for 24h, and then heat-treated at 43°C for a further 1h. The viability, membrane surface ultrastructure and Hsp70 expression of striatum neurons were all observed. Furthermore, the effects of quercetin an inhibitor of Hsp70 synthesis were also investigated. Compared to the heatstroke group, GGA delayed Tre in reaching 42.1°C (P<0.05) and prolonged the survival time after heatstroke (P<0.01). The LDH releasing percentage decreased in GGA groups (P<0.05, P<0.01) compared to the heat-treatment group and increased in quercetin groups (P<0.05) compared to GGA group. Results from AFM showed that GGA protected membrane surface ultrastructure against heat injury. In addition, results from Western blot showed that GGA-induced Hsp70 expression of neurons both in normal and heat-treatment conditions (P<0.01, P<0.05) and quercetin inhibited GGA-induced Hsp70 expression (P<0.05). Therefore, GGA had protective effects against heat injury in striatum neurons and rat heatstroke. Quercetin inhibited GGA-induced Hsp70 expression and prevented GGA-protective effects, which indicated that this protection was dependent on the Hsp70 synthesis.

Abstract
Prevention and amelioration of Mibyou (sub-healthy condition) is the critical target for disease prevention including age-related diseases and cancer although the Mibyou condition is not yet pathologically defined. Since the oxidative stress is an underlying basic etiology associated with many diseases and aging, the psychologically induced oxidative stress, especially in the brain was supposed as one of the pathology of Mibyou. Several traditional herbal prescriptions applied for the brain disorder were found effective to prevent cerebral oxidative stress induced by ischemia/reperfusion and also under psychological distress produced by whiskers cut in mice. Shengmai San comprising three herbs, Panax ginseng, Ophiopogon japonicus and Schisandra chinensis is a traditional herbal medicine formula having a long history of using as a remedy and clinical prescription to treat coronal heart diseases. Multifunctional aspect of traditional herbal prescription was discussed in terms of preventing oxidative injury in the brain using Shengmai San as a typical prescription.

Abstract
The preventive effects of ACTICOA powder (AP), a cocoa polyphenolic extract, on free radicals produced by leucocytes in rats after heat exposure (HE) and its protective effects on subsequent cognitive impairments were assessed. AP or vitamin E, the antioxidant reference, was orally administered to rats for 14 d before HE at 40 degrees C temperature during 2 h. The day after HE, free radical production by leucocytes in rats treated with AP or vitamin E was significantly reduced as compared to control. Unlike controls, AP- and vitamin E-treated rats discriminated between active lever and inactive levers in a light extinction paradigm. In the Morris water maze, escape latencies before reaching the hidden platform by AP- and vitamin E-treated rats decreased throughout testing. The daily oral administration of AP or vitamin E protected rats from cognitive impairments after HE by counteracting the overproduction of free radicals.

Abstract
When rats were exposed to high environmental temperature (e.g., 42 or 43 degrees C), hyperthermia, hypotension, and cerebral ischemia and damage occurred during heat stroke were associated with increased production of free radicals (specifically hydroxyl radicals and superoxide anions), higher lipid peroxidation, lower enzymatic antioxidant defenses, and higher enzymatic pro-oxidants in the brain of heat stroke-affected rats. Pretreatment with conventional hydroxyl radical scavengers (e.g., mannitol or alpha-tocopherol) prevented increased production of hydroxyl radicals, increased levels of lipid peroxidation, and ischemic neuronal damage in different brain structures attenuated with heat stroke and increased subsequent survival time. Heat shock preconditioning (a mild sublethal heat exposure for 15min) or regular, daily exercise for at least 3 weeks, in addition to inducing overproduction of heat shock protein 72 in multiple organs including brain, significantly attenuated the heat stroke-induced hyperthermia, hypotension, cerebral ischemia and damage, and overproduction of hydroxyl radicals and lipid peroxidation. The precise function of heat shock protein 72 are unknown, but there is considerable evidence that these proteins are essential for survival at both normal and elevated temperatures. They also play a critical role in the development of thermotolerance and protection from oxidative damage associated with cerebral ischemia and energy depletion during heat stroke. In addition, Shengmai San or magnolol (Chinese herbal medicines) or hypervolemic hemodilution (produced by intravenous infusion of 10% human albumin) is effective for prevention and repair of ischemic and oxidative damage in the brain during heat stroke. Thus, it appears that heat shock protein 72 preconditioning induced by prior heat shock or regular exercise training, as well as pretreatment with Shengmai San or magnolol is able to prevent the oxidative damage during heat stroke. On the other hand, hypervolemic hemodilution, Shengmai San, or magnolol is able to treat the oxidative damage after heat stroke onset.

Abstract
Neurodegenerative brain disorders such as Alzheimer's disease (AD) have been well investigated. However, significant methods for the treatment of the promotion and progression of AD are unavailable to date. Recent studies suggested that the redox imbalance and the accumulation of amyloid-beta (Abeta) peptide occurring in the brain of AD patients lead to oxidatively-induced apoptotic cell death. Here, we show the effects of Shengmai-san (SMS) on Abeta-induced cytotoxicity in PC-12 cells. SMS dose-dependently attenuated the cytotoxicity by Abeta incubation and also prevented the morphological damage in neurites of the PC-12 cells. Hemeoxygenase-1 and glutathione peroxidase-1 expressions were increased by SMS pretreatment. SMS decreased the phosphorylation level of c-jun amino-terminal kinase (JNK) and the activity of caspase-3, which were enhanced by Abeta incubation. Of importance, SMS treatment promoted neurite outgrowth. These data demonstrated dual roles of SMS in PC-12 cells. SMS prevents the apoptosis through the enhancement of anti-oxidant enzymes and inhibition of the JNK signaling pathway with the promotion of nerve cell maturation, thus suggesting benefits of SMS for the treating of neurodegenerative diseases. It may also be beneficial not only for the treatment of brain disorders but also for other diseases caused by oxidative stress.

Abstract
The purpose of the present study was to assess the therapeutic effect of hypothermic retrograde jugular vein flush (HRJVF) on heatstroke. HRJVF was accomplished by infusion of 4 degrees C isotonic sodium chloride solution via the external jugular vein (1.7 mL/100 g of body weight over 5 min). Immediately after the onset of heatstroke, anesthetized rats were divided into 2 major groups and given the following: 36 degrees C or 4 degrees C isotonic sodium chloride solution, i.v. They were exposed to ambient temperature of 43 degrees C to induce heatstroke. Another group of rats was exposed to room temperature (24 degrees C) and used as normothermic controls. When the 36 degrees C saline-treated rats underwent heat exposure, their survival time values were found to be 23 to 28 min. Immediately after the onset of heatstroke, resuscitation with an i.v. dose of 4 degrees C saline significantly improved survival during heatstroke (208-252 min). All heat-stressed animals displayed systemic inflammation and activated coagulation, evidenced by increased tumor necrosis factor alpha, prothrombin time, activated partial thromboplastin time, and d-dimer, and decreased platelet count and protein C. Biochemical markers evidenced cellular ischemia and injury/dysfunction: plasma levels of blood urea nitrogen, creatinine, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, and alkaline phosphatase; and striatal levels of glycerol, glutamate, and lactate/pyruvate; dihydroxy benzoic acid, lipid peroxidation, oxidized-form glutathione reduced-form glutathione, dopamine, and serotonin were all elevated during heatstroke. Core and brain temperatures and intracranial pressure were also increased during heatstroke. In contrast, the values of mean arterial pressure, cerebral perfusion pressure, and striatal levels of local blood flow, partial pressure of oxygen, superoxide dismutase, catalase, glutathione peroxidase, and glutathions reductase activities were all significantly lower during heatstroke. The circulatory dysfunction, systemic inflammation, hypercoagulable state, and cerebral oxidative stress, ischemia, and damage during heatstroke were all significantly suppressed by HRJVF. These findings demonstrate that brain cooling caused by HRJVF therapy may resuscitate persons who had a stroke by attenuating cerebral oxidative stress, systemic inflammation, activated coagulation, and tissue ischemia/injury during heatstroke.

Abstract
1. The aim of the present review is to summarize clinical observations and results of animal models that advance the knowledge of the attenuation of cerebrovascular dysfunction in the setting of heat stroke. It is a narrative review of selected published literature from Medline over the period 1959-2005. 2. All heat-stressed rodents, even under general anaesthesia, have hyperthermia, systemic inflammation, hypercoagulable state, arterial hypotension and tissue ischaemia and injury in multiple organs. These findings demonstrate that rodent heat stroke models can nearly mirror the full spectrum of human heat stroke. Experimental heat stroke fulfills the empirical triad used for the diagnosis of classical human heat stroke, namely hyperthermia, central nervous system alterations and a history of heat stress. 3. These physiological dysfunctions and survival during heat stroke can be improved by whole-body or brain cooling therapy adopted immediately after the onset of heat stroke. 4. However, in the absence of body or brain cooling, these heat stroke reactions can still be reduced by the following measures: (i) fluid replacement with 3% NaCl solution, 10% human albumin or hydroxyethyl starch; (ii) intravenous delivery of anti-inflammatory drugs, free radical scavengers or interleukin-1 receptor antagonists; (iii) hyperbaric oxygen therapy; or (iv) transplantation of human umbilical cord blood cells. 5. In addition, before initiation of heat stress, prior manipulations with one of the following measures was found to be able to protect against heat stroke reactions: (i) systemic delivery of alpha-tocopherol, mannitol, inducible nitric oxide synthase inhibitors, mu-opioid receptor antagonists, endothelin ETA receptor antagonists, serotoninergic nerve depletors or receptor antagonists, or glutamate receptor antagonists; or (ii) heat shock protein 72 preconditioning. 6. There is compelling evidence that cerebrovascular dysfunction is an attractive target for therapy in heat stroke.

Abstract
Heatstroke is a life-threatening illness characterized by an elevated core body temperature (>40 degrees C) and dysfunction of central nervous system, which results in delirium, convulsions, or coma. Despite adequate hypothermia or other care-therapy, heatstroke is often fatal. On the basis of our knowledge of the pathophysiology on heatstroke, we hypothesized that heatstroke is a form of hyperthermia associated with the acute physiological alterations, the cytotoxicity of heat, systemic inflammatory response, oxidative damage and attenuated heat-shock response leading to a syndrome of multi-organ dysfunction. In view of above-mentioned situation, the physiological factors underlying heatstroke and the corresponding possible therapeutic strategies to avert the complications of this disorder would be summarized in this review so as to provide some therapeutic guidelines for heatstroke. Heatstroke is a very complicated process. Acute physiological alterations, such as low arterial hypotension, intracranial hypertension, cerebral hypoperfusion, cerebral ischemia, and increased intracellular metabolism rate, occurred while exposed to a high ambient temperature. Hyperpyrexia caused cytotoxicity, resulting the degradation and aggregation of extensive intracellular proteins, influencing the change of membrane stability and fluidity, damaging the transmembrane transport of protein and the function of surface receptor, and inducing different cytoskeletal changes. Heatstroke resembles sepsis in many aspects, and endotoxemia and cytokines may be implicated in its pathogenesis. The concentration of interleukin-6 was positively correlated with the severity of heatstroke. The excessive accumulation of cytotoxic free radicals and oxidative damage may occur in the brain tissues during the genesis and development of heatstroke. The circulatory shock and cerebral ischemia resultant from heatstroke correlated closely with the free radicals (especially free radicals of peroxide and superoxide), the peroxidation of lipids, and low activity of antioxidase in the brain. Heat-shock proteins (Hsps) played a critical role during the process obtaining thermotolerance, therefore, protected from stress-induce cellular damage. Host factors or physiologically limiting factors, for instance, aging, existing illness, dehydration, deep insomnia, lack of acclimation to heat, inadequate physical fitness, and certain genetic polymorphisms were associated with a low level of Hsps expression and might favor the progression from heat stress to heatstroke. Some measures, such as molecular chaperonines, anti-inflammatory agents, antioxidant agents, and modulators of Hsps would be good for the patients with heatstroke.

Abstract
Naltrexone, a nonselective antagonist of opioid receptors, is found to be beneficial in protecting against heatstroke. Further investigation using selective mu, delta, and kappa opioid receptor antagonists are needed to prove the involvement of specific receptors in heatstroke. Rats under sodium pentobarbital anesthesia were exposed to high ambient temperature of 43 degrees C to induce heatstroke. Control rats were exposed to 24 degrees C. In rats treated with normal saline 20 minutes before heat stress, the values for survival time were found to be 89-101 minutes. Intravenous administration of CTAP (a selective mu-opioid receptor antagonist; 50-200 microg/kg), but not nor-binaltorphimine (20-200 microg/kg; a kappa-opioid receptor antagonist) or ICI-174864 (50-500 microg/kg; a delta-opioid receptor antagonist), significantly increased the survival time to new values of 180-212 minutes. In vehicle-treated rats after heatstroke onset, the values for core temperature, intracranial pressure, and the extracellular markers for ischemia (eg, glutamate and lactate/pyruvate ratio) or damage (eg, glycerol) and neuronal damage scores in striatum were significantly higher than those of normothermic controls. In contrast, the values for mean arterial pressure, cerebral perfusion pressure, cerebral blood flow, and brain partial pressure of O2 were significantly lower than those of normothermic controls. The heatstroke-induced hyperthermia, arterial hypotension, intracranial hypertension, cerebral hypoperfusion and hypoxia, and increased levels of cellular ischemia and damage markers in striatum were all significantly attenuated by prior administration of CTAP. The data indicate that prior antagonism of mu-opioid receptors protects against circulatory shock and cerebral ischemia during heatstroke.

Abstract
1. There is evidence that the induction of inducible nitric oxide synthase (iNOS) and peroxynitrite by ischaemia/reperfusion may lead to renal cell injury. Herein, we investigated whether Sheng mai san (SMS), a Chinese herbal medicine, protects against renal ischaemic injury during heat stroke by reducing iNOS-dependent nitric oxide (NO) and peroxynitrite formation. 2. Urethane-anaesthetized rats were exposed to heat stress (ambient temperature 43 degrees C) to induce heat stroke. Control rats were exposed to 24 degrees C. Mean arterial pressure and renal blood flow after the onset of heat stroke were significantly lower in heat stroke rats than in control rats. However, both colonic temperature and renal damage score were greater in heat stroke rats compared with control rats. Similarly, plasma NO, creatinine and blood urea nitrogen (BUN), as well as the renal immunoreactivity of iNOS and peroxynitrite, were significantly higher in heat stroke rats compared with their normothermic controls. 3. Pretreatment with SMS (1.2 g/day per rat for 7 consecutive days before the initiation of heat stress) significantly attenuated the heat stroke-induced arterial hypotension, hyperthermia, renal ischaemia and damage, the increased renal immunoreactivity of iNOS and peroxynitrite and the increased plasma levels of NO, creatinine and BUN. Pretreatment with SMS resulted in a prolongation of survival time in heat stroke. 4. The results of the present study suggest that SMS protects against renal ischaemic damage by reducing iNOS-dependent NO and peroxynitrite production during heat stroke.

Abstract
The aim of the present study was to ascertain whether the possible occurrence of overproduction of inducible nitric oxide synthase (iNOS)-dependent nitric oxide (NO) in the brain and inflammatory cytokines in the peripheral blood exhibited during heat stroke can be reduced by prior administration of Shengmai San, a Chinese herbal medicine. Aminoguanidine, an iNOS inhibitor, was evaluated at the same time as a reference (positive control). Urethane-anesthetized rats were exposed to heat stress (ambient temperature of 43 degrees C) to induce heat stroke. Control rats were exposed to 24 degrees C. Mean arterial pressure and cerebral blood flow after the onset of heat stroke were all significantly lower than in control rats. However, cerebral iNOS immunoreactivity and NO levels were all greater after the onset of heat stroke. The serum levels of interleukin-1beta, interleukin-6, and tumor necrosis factor-alpha were all increased after the onset of heat stroke. Shengmai San (1.2 g/ml per rat) or aminoguanidine (30 micromol/ml per rat) was administered orally, daily, and consecutively for 7 days before the initiation of heat stress; and this significantly attenuated the heat stress-induced arterial hypotension, cerebral ischemia, and increased levels of brain iNOS-dependent NO production and serum cytokines formation. Shengmai San shared with the aminoguanidine almost the same efficacy in reducing iNOS-dependent NO and cytokines overproduction during heat stroke. These results suggest that Shengmai San or aminoguanidine protects against heat stroke-induced arterial hypotension and cerebral ischemia by inhibition of iNOS-dependent NO overproduction in the brain and excessive accumulation of several inflammatory cytokines in the peripheral blood stream.
