Ethnopharmacological relevance The history of Chinese spices has received increasing attention in recent years, but little research been carried out on where they fit on the food-medicine continuum for early China, during the formation of the classical medical system. This paper describes how the synaesthetic qualities of spices attracted a particular analysis in that emerging system which serves to mark them as different to other medical materials and foodstuffs. We aim to clarify the special role created for spices to accommodate their boundary-crossing synaesthetic action on the body. Material and methods This paper analyses the contents of several spice bags excavated in 1972 from a tomb that was closed in the second century BCE. It uses archaeological reports of material culture together with the early Chinese textual record, extant in both manuscripts and received texts, to bring out the role of spices in ritual, food and medicine. Results Noting that the flavours and aromas of early China were assigned physiological potency in the first centuries BCE, we argue that by medieval times the unique synaesthetic role that spices played in mediating the senses was systematically medicalised. While being deployed for the purpose of curing disease in medicine, they also remained within the realm of everyday healthcare, and religious practice, deployed both as aromatics to perfume the environment, attracting benign spirits, but also to ward off the agents of disease, as well as for enhancing health through their use in cookery. Conclusion While foodstuffs entered the digestive system spices were all considered ‘pungent’ in the emerging clasical medical system. They acted on the body through the nose and lungs, making them neither food nor drug. This implicit categorisation medicalised spices which, like music, could affect the passions and lighten the spirit, codifying observations about the impact on the body of the ritual environment.

Abstract: Ethnopharmacological relevance: Though inflammatory response is beneficial to body damage repair, if it is out of control, it can produce adverse effects on the body. Although purely western anti-inflammatory drugs, orthodox medicines, can control inflammation occurrence and development, it is not enough. The clinical efficacy of anti-inflammation therapies is unsatisfactory, thus the search for new anti-inflammation continues. Chinese Material Medica (CMM) remains a promising source of new therapeutic agents. CMM and herbal formulae from Traditional Chinese Medicine (TCM), unorthodox medicines, play an improtant anti-inflammatory role in multi-targets, multi-levels, and multi-ways in treating inflammation diseases in a long history in China, based on their multi-active ingredient characteristics. Due to these reasons, recently, CMM has been commercialized as an anti-inflammation agent which has become increasingly popular in the world health drug markets. Major research contributions in ethnopharmacology have generated vast amount of data associated with CMM in anti-inflammtion aspect. Therefore, a systematic introduction of CMM anti-inflammatory research progress is of great importance and necessity. Aim of the study: This paper strives to describe the progress of CMM in the treatment of inflammatory diseases from different aspects, and provide the essential theoretical support and scientific evidence for the further development and utilization of CMM resources as a potential anti-inflammation drug through a variety of databases. Material and methods: Literature survey was performed via electronic search (SciFinder®, Pubmed®, Google Scholar and Web of Science) on papers and patents and by systematic research in ethnopharmacological literature at various university libraries. Results: This review mainly introduced the current research on the anti-inflammatory active ingredient, anti-inflammatory effects of CMM, their mechanism, anti-inflammatory drug development of CMM, and toxicological information. Conclusion: CMM is used clinically to treat inflammation symptoms in TCM, and its effect is mediated by multiple targets through multiple active ingredients. Although scholars around the world have made studies on the anti-inflammatory studies of CMM from different pathways and aspects and have made substantial progress, further studies are warranted to delineate the inflammation actions in more cogency models, establish the toxicological profiles and quality standards, assess the potentials of CMM in clinical applications, and make more convenient preparations easy to administrate for patients. Development of the clinically anti-inflammatory drugs are also warranted. [Copyright &y& Elsevier]

Vinegar-baked Radix Bupleuri (VBRB) is usually used to focus other drugs effect on liver in traditional Chinese medicine (TCM). However, no sufficient scientific data are available to support this concept. In this paper, the liver targeting enhancing effect of VBRB on rhein was investigated. 432 of rats were divided into two large groups according to the dose of rhein, low dose group of rhein (LDGR) and high dose group of rhein (HDGR). In each group, the rats were further divided into four subgroups, rhein control and rhein co-administered with three different doses of VBRB peroral. Concentrations of rhein and its metabolite in different tissues were determined by HPLC. Compared to the control group, VBRB significantly increased the distribution of both rhein and its metabolite in liver and meanwhile decreased their distribution in other tissues, indicating a strong liver targeting enhancing effect. This liver targeting effect of VBRB depended on the dose of VBRB and rhein. Low and high dose of VBRB had a more strong effect than medium dose in HDGR; high dose of rhein was more sensitive than low dose of rhein (P <0.05). Rhein existed in two forms after peroral administration in vivo. It was found that the liver targeting effect of VBRB was more remarkable with the native form of rhein compared to its derivative form. The results of this paper demonstrated that co-administration with VBRB is a simple and efficiencient method for liver targeting therapy, and the meridine guide theory of TCM was credible.

Ethnopharmacological relevance Sophora flavescens (Fabaceae), also known as Kushen (Chinese: 苦参), has been an important species in Chinese medicine since the Qin and Han dynasties. The root of Sophora flavescens has a long history in the traditional medicine of many countries, including China, Japan, Korea, India and some countries in Europe. In traditional Chinese medicine (TCM), Sophora flavescens has been used extensively, mainly in combination with other medicinal plants in prescriptions to treat fever, dysentery, hematochezia, jaundice, oliguria, vulvar swelling, asthma, eczema, inflammatory disorders, ulcers and diseases associated with skin burns. The aim of this review is to provide updated and comprehensive information regarding the botany, ethnopharmacology, phytochemistry, biological activities and toxicology of Sophora flavescens and to discuss possible trends and opportunities for further research on Sophora flavescens . Materials and methods We systematically searched major scientific databases (PubMed, Elsevier, SpringerLink, Google Scholar, Medline Plus, ACS, “ Da Yi Yi Xue Sou Suo ( http://www.dayi100.com/login.jsp )”, China Knowledge Resource Integrated (CNKI) and Web of Science) for information published between 1958 and 2015 on Sophora flavescens . Information was also acquired from local classic herbal literature, conference papers, government reports, and PhD and MSc dissertations. Results The broad spectrum of biological activities associated with Sophora flavescens has been considered a valuable resource in both traditional and modern medicine. Extracts are taken either orally or by injection. More than 200 compounds have been isolated from Sophora flavescens , and the major components have been identified as flavonoids and alkaloids. Recent in vitro and in vivo studies indicate that at least 50 pure compounds and crude extracts from Sophora flavescens possess wide-ranging antitumor, antimicrobial, antipyretic, antinociceptive, and anti-inflammatory pharmacological abilities. The anticancer and anti-infection abilities of these components are especially attractive areas for research. Conclusions Sophora flavescens is a promising traditional medicine, but there is a need for more precise studies to test the safety and clinical value of its main active crude extracts and pure compounds and to clarify their mechanisms of action. Moreover, some existing studies have lacked systematic methods and integration with the existing literature, and some of the experiments were isolated, used small sample sizes and were unreliable. More validated data are therefore required. [ABSTRACT FROM AUTHOR]

Ethnopharmacological relevance Seven species from the genus Dictamnus are distributed throughout Europe and North Asia and only two species grow in China. One is Dictamnus dasycarpus Turcz., which could be found in many areas of China and has been recorded in Chinese Pharmacopoeia . The other is Dictamnus angustifolius G. Don ex Sweet, which is only present in Xinjiang province and has been used as an alternative for Dictamnus dasycarpus in the local for the treatment of rheumatism, bleeding, itching, jaundice, chronic hepatitis and skin diseases. The present paper reviewed the traditional uses, phytochemistry, pharmacology and toxicology of the genus Dictamnus . Materials and methods Information on the Dictamnus species was collected from classic books about Chinese herbal medicine and globally accepted scientific databases including PubMed, Elsevier, ASC, Scopus, Google Scholar, Web of Science, CNKI and others. Results About 170 chemical compounds, which include quinoline alkaloids, limonoids, sesquiterpenes, coumarins, flavonoids and steroids, have been isolated from the genus Dictamnus . The characteristic and active constituents of Dictamnus species are considered to be quinoline alkaloids and limonoids, which exhibited a broad spectrum of biological activities such as anti-cancer, anti-inflammation, anti-microbe, anti-platelet-aggregation, vascular-relaxation, anti-insect, anti-HIV, anti-allergy and neuroprotection. Moreover, quinoline alkaloids and limonoids could be used as quality control markers to distinguish different species from the genus Dictamnus . However, there were also some reports on the toxic hepatitis and phototoxic effect of Dictamnus species, and the related research needs to be further studied. Conclusion In this review, we summarized the chemical constituents, pharmacology, quality control and toxicology of the species from genus Dictamnus . Phytochemical investigations indicated that quinoline alkaloids and limonoids were the major bioactive components with potential cytotoxic, neuroprotective, anti-inflammatory, antimicrobial, anti-platelet-aggregation and vascular relaxing activities. These two kinds of compounds have attracted great interests in the past few years and may have great potential to be new drug lead compounds. [ABSTRACT FROM AUTHOR]

More bioactive components should be identified using bioactivity-guided isolation strategies, and the possible mechanism of action as well as potential synergistic or antagonistic effects of multi-component mixtures derived from safflower need to be evaluated integrating pharmacological, pharmacokinetic, bioavailability-centered and physiological approaches. Further studies on safflower can lead to the development of new drugs and therapeutics for various diseases, and how to utilize it better should be paid more attention to. [ABSTRACT FROM AUTHOR]

Abstract: Ethnobotanical relevance: Due to the global rise in the use of traditional Chinese medicine (TCM), Chinese materia medica (medicinal materials, or CMM) are giving cause for concern over their evidence base, safety/possible toxicity, questionable quality and use of endangered species of both animals and plants. However, little if anything is actually known about the range of species used to produce CMM used in Europe and even in China. This study represents the first attempt to identify and compare the most important CMM used in both regions, to begin the process of assessing the risks to public health and possible future benefits. Materials and methods: Data were collected from a convenience sample of TCM practitioners in the EU and mainland China, using a paper/online survey. Among other questions, respondents were asked (1) which conditions they most commonly treated using CMM and the likelihood of them using herbal manufactured products and decoctions in addition to raw herbs; (2) the perceived frequency with which they observed adverse events to CMM; (3) the frequency and reasons for use of 1 herbal formula and 6 specific individual herbs; (4) an open question about other CMM they used, including materials of non-plant origin. Data were entered into PASW statistics package and analysed using frequency tables, cross-tabulations and chi-squared tests to compare EU and Chinese results. Results: From a total of 747 useable questionnaires (420 from China, 327 from the EU) of those responding from the EU, TCM was generally more commonly used for obstetric/gynaecological and dermatological conditions, compared to neurological and gastrointestinal diseases in China. Disorders treated by Chinese practitioners were more varied, and often more serious, than those treated by their European counterparts, and the range of materials used in China was wider. The potential for toxicity was not high in either region, but although greater in China due to the use of more potent CMM, the incidence of side effects was perceived to be higher by EU practitioners. Conclusions: Very few of the species used to prepare CMM in the EU in this study give rise to safety concerns from what is known from the scientific and other literature, and in China only a few toxic CMM appear to be commonly used, some of them only after processing and mainly for serious disorders. The main cause for concern is likely to be interaction with prescribed medication, especially in central nervous system and cardiovascular conditions where drug interactions have previously been reported most frequently and which would currently be more applicable in China than Europe.

Abstract: Ethnopharmacological relevance: Polygonum cuspidatum Sieb. et Zucc. (Polygonum cuspidatum), also known as Reynoutria japonica Houtt and Huzhang in China, is a traditional and popular Chinese medicinal herb. Polygonum cuspidatum with a wide spectrum of pharmacological effects has been used for treatment of inflammation, favus, jaundice, scald, and hyperlipemia, etc. Aim of the review: The present paper reviews the traditional applications as well as advances in botany, phytochemistry, pharmacodynamics, pharmacokinetics and toxicology of this plant. Finally, the tendency and perspective for future investigation of this plant are discussed, too. Materials and methods: A systematic review of literature about Polygonum cuspidatum is carried out using resources including classic books about Chinese herbal medicine, and scientific databases including Pubmed, SciFinder, Scopus, the Web of Science and others. Results: Polygonum cuspidatum is widely distributed in the world and has been used as a traditional medicine for a long history in China. Over 67 compounds including quinones, stilbenes, flavonoids, counmarins and ligans have been isolated and identified from this plant. The root of this plant is used as the effective agent in pre-clinical and clinical practice for regulating lipids, anti-endotoxic shock, anti-infection and anti-inflammation, anti-cancer and other diseases in China and Japan. Conclusion: As an important traditional Chinese medicine, Polygonum cuspidatum has been used for treatment of hyperlipemia, inflammation, infection and cancer, etc. Because there is no enough systemic data about the chemical constituents and their pharmacological effects or toxicities, it is important to investigate the pharmacological effects and molecular mechanisms of this plant based on modern realization of diseases’ pathophysiology. Drug target-guided and bioactivity-guided isolation and purification of the chemical constituents from this plant and subsequent evaluation of their pharmacologic effects will promote the development of new drug and make sure which chemical constituent or multiple ingredients contributes its pharmacological effects. Additionally, chemicals and their pharmacological effects of the other parts such as the aerial part of this plant should be exploited in order to avoid resource waste and find new chemical constituents.

Abstract: Ethnopharmacological relevance:: Abelmoschus manihot (L.) Medik. var. manihot is one of the most commonly used Chinese medicines and has played an important role in treating chronic glomerulonephritis and diabetic nephropathy. Aim of the study:: Metabolites identification of traditional Chinese medicine (TCM) is a complex and time-consuming process due to the complicity of TCM and subsequent large number of detected ions. In this paper, UPLC–MS combined with pattern recognition analysis approach were used to simplify and quicken the identification of the metabolites of Abelmoschus Manihot. Materials and methods:: Rat urine samples were collected before (as control sample) and after Abelmoschus Manihot administration. Pattern recognition analysis method was used to differentiate components between Abelmoschus Manihot-treated group and its controlled comparison. These components could be considered as Abelmoschus Manihot-related metabolites in vivo. Results:: LC–MS based metabolomics could be an advanced tool to help us find metabolites with regards to its capacity of processing large datasets, differentiating and classifying of sample groups, as well as its indiscriminative nature of biomarker and metabolite identification. Using this method, seven metabolites were identified, which are flavonoid aglycone glucuronidation, sulfatation, and methylation metabolites. Conclusion:: Our results showed that UPLC–MS based- pattern recognition analysis approach can be used to quickly identify Abelmoschus Manihot related metabolites in biological fluids. Furthermore, this work demonstrates the potential application of combining the UPLC–MS approach with the metabolomics approach in identifying the metabolites of TCM. [Copyright &y& Elsevier]

Abstract: Ethnopharmacological relevance: The lateral root of Aconitum has been popularly used in traditional Chinese medicine (TMC) known as Fuzi which is beneficial for the treatment of various diseases, such as rheumatism, painful joints, syncope and bronchial asthma. However, it has a potential carditoxicity with a relatively narrow margin of safety. Aim of the study: This paper was designed to explore the mechanisms of Fuzi's toxicity and find out potential tissue-specific biomarkers of toxic effects. Material and methods: A myocardial lipidomics based on ultraperformance lipid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UHPLC/Q-TOF MS) was developed to compare three cardiac lipid extraction methods and investigate the changes of lipids in mice heart of three different dosage groups. In addition, we concurrently inspected the biochemical parameters in plasma, observed the histology of the heart and recorded the electrocardiogram (ECG). Results: The cardiotoxicity of Fuzi was dose-dependent, and the high-dose group obviously manifested the heart damage in histology and a certain degree of arrhythmia. Significant changes of 14 lipid metabolites which primarily involved in phospholipid metabolism, sphingolipid metabolism, saturated fatty acid oxidation and unsaturated fatty acid peroxidation were identified and considered as the potential biomarkers of Fuzi toxicity. Conclusion: The lipidomics approach is helpful to search potential tissue-specific biomarkers and understand the underlying mechanisms of Fuzi toxicity on the heart. [Copyright &y& Elsevier]

Abstract: Arctiin, an important lignan compound in Fructus Arctii, has been reported to possess various kinds of bioactivities. Previous studies on the pharmacokinetic of arctiin after oral administration showed that it had a rapid absorption phase followed by a sharp but lasting disappearance. To gain deep insight into the action mechanism of arctiin, the excretion and metabolism of arctiin in vivo should be further studied. In this paper, three metabolites were isolated and identified in rat feces as (−)-enterolactone (M-1), (−)-arctigenin (M-2) and [(2R,3R)-2-(3′-hydroxybenzyl)-3-(3″,4″-dimethoxybenzyl)-butyrolactone] (M-3). Based on the structures of three metabolites, possible metabolic pathways of arctiin in rats are proposed. At the same time, the cumulative excretion rate of arctiin and its metabolites in rat urine and feces were determined, indicating that arctiin was excreted 19.84% in urine and 1.80% in feces, respectively, enterolactone, the most main metabolite, was excreted 35.80% in feces. These results provide very important information for understanding the metabolism and excretion of arctiin in vivo and speculating its action mechanism, they can provide useful information and reference for further metabolic investigations on arctiin in humans.

Abstract: Triptolide, a diterpenoid epoxide, is one of the major active ingredients of Tripterygium wilfordii Hook F, a woody vine plant called lei gong teng in China, which is used in traditional Chinese Medicine (TCM) for treating many diseases. In this paper, we investigate the relation between inhibition of mitochondrial respiratory chain and liver injury induced by triptolide. Results indicate that the secondary β-oxidation impairment caused by inhibition of mitochondrial respiratory chain is involved in triptolide-induced liver injury, which featured by microvesicular steatosis, hyperlactacidemia and enhanced oxidant stress, although other mechanisms of triptolide-induced liver injury may also exist.

Abstract: Ethnopharmacological relevance: Swertia chirayita, a medicinal herb endemic to the Tibetan region, is used as a special remedy for liver disorders. The hepatoprotective activity of its plant extracts has been associated with its antioxidant activity. This paper aims to investigate the in vitro and in vivo antioxidant effects of Swertia chirayita extracts (SCE). Materials and methods: Antioxidant ability of Swertia chirayita was investigated by employing several established in vitro methods. In vivo antioxidant activity was tested against CCl4-induced toxicity in mice. The levels and activities of malondialdehyde (MDA) and antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH), were then assayed using standard procedures. Results: SCE exhibited strong antioxidant ability in vitro. The liver and kidney of CCl4-intoxicated animals exhibited a significant (p <0.001) decrease in SOD, CAT, and GSH levels. Additionally, these organs exhibited a significant (p <0.001) increase in MDA level. CCl4 did not exhibit toxicity on mice treated with SCE and Vitamin E. The effects of Swertia chirayita (three dosages) were comparable to those of Vitamin E, except in MDA level in the liver and GSH level in the kidney (p <0.05). Conclusion: This study suggests that the ethanolic extract of Swertia chirayita possesses in vitro and in vivo antioxidant effects. This supports the traditional use of Swertia chirayita in Tibetan medicine to cure liver diseases. [Copyright &y& Elsevier]

Abstract: Phlomis umbrosa Turcz has been used as the traditional medicine for thousands of years in China. In this paper, the acetic acid-induced writhing test, the hot plate test, the carrageenan-induced paw edema test, the xylene-induced ear swelling test, and the acetic acid-induced Evans blue leakage and leukocyte infiltration test were used to investigate the antinociceptive and anti-inflammatory activities of the aqueous extract of this plant (25, 50 and 100mg/kg i.p.). Good dose-dependent effects were obtained in most of these tests, except in the hot plate test and the acetic acid-induced Evans blue leakage test. TLC and HPLC analyses showed iridoid glucosides were the main compositions of this extract. These findings suggested that the aqueous extract of P. umbrosa has significant antinociceptive and anti-inflammatory activities. [Copyright &y& Elsevier]

Abstract: Ethnopharmacological relevance: Traditional Chinese medicine (TCM) has been used in clinical practice for several thousand years. TCM has played an indispensable role in the prevention and treatment of diseases, especially the complicated and chronic ones. Pharmacokinetic study on active constituents in herbal preparations is a good way for us to explain and predict a variety of events related to the efficacy and toxicity of TCM. Aim of the study: A selective and sensitive HPLC–MS/MS method was first developed and validated for the determination of luteolin, kaempferol, apigenin, quercetol, and isorhamnetin in rat plasma. Materials and methods: The LC system consisted of an Agilent Technologies Series 1200 system (Agilent, USA) equipped with an automatic degasser, a quaternary pump, and an autosampler. Chromatographic separations were performed on a Waters SunFire™ C18 column (150mm×4.6mm, 5μm), and the column temperature was maintained at 25°C and the sample injection volume was 20μL. The current LC–MS/MS assay was validated for linearity, intra-day and inter-day precisions, accuracy, extraction recovery and stability. Results: The validated method was successfully applied to monitoring the concentrations and pharmacokinetic studies of five flavone compounds in rat plasma after a single oral administration of Verbena officinalis L. extract with a dosage of 8.0mL/kg. The time to reach the maximum plasma concentration (T max1) was 0.48±2.14h for luteolin, 0.25±0.13h for kaempferol, 0.97±1.08h for apigenin, 1.04±4.25h for quercetol and 0.25±0.16h for isorhamnetin, and the maximum plasma concentration (T max2) was 3.97±1.48h, 4.05±0.46h, 4.33±0.58h, 2.99±0.48h and 4.02±0.34h. The elimination half-time (t 1/2) of luteolin, kaempferol, apigenin, quercetol and isorhamnetin was 4.02±0.81, 7.65±0.71, 3.30±0.83, 4.55±0.49 and 5.56±1.32h, respectively. Conclusions: This paper described a simple, sensitive and validated LC–MS/MS method for simultaneous determination of luteolin, kaempferol, apigenin, quercetol and isorhamnetin in rat plasma after oral administration of V. officinalis L. extract, and investigated on their pharmacokinetic studies as well, with a short run time of 5min.

Abstract: Authentication is fundamental for the standardization of Chinese Materia Medica. Macroscopic identification, an important method of authentication, has a long history rooted in practice and experience over generations. In ancient times, macroscopic features were used not only to identify the genuineness, but also to evaluate the quality of Chinese medicinal materials (CMMs). In many ancient documents, picturesque terms were used to describe the quality of certain specific CMMs. These traditional macroscopic descriptions used for identification are filled with characteristics, quality descriptions, and specifications of CMM that need to be confirmed by modern scientific analysis. In this paper, the essential and fundamental components of macroscopic identification are introduced. As the quality and macroscopic characteristics of CMM are traditionally thought to be closely related, modern scientific approaches to confirm the validity of these associations are discussed. This review clarifies the role of macroscopic features in the quality assessment of CMM. [Copyright &y& Elsevier]

Abstract: Epimedium (Berberidaceae), is a genus of about 52 species in the family Berberidaceae, which also known as Rowdy Lamb Herb, Xianlinpi, Barrenwort, Bishop''s Hat, Fairy Wings, Horny Goat Weed, and Yangheye or Yin Yang Huo (Chinese: ▪). Many plants have been proven to possess efficacy on sexual dysfunction and osteoporosis in traditional Chinese medicine (TCM). The paper reviews the ethnopharmacology, the biological activities and the correlated chemical compounds of Epimedium species. More than 260 compounds have been isolated; among them prenyl-flavonoids are the major constituents and also important chemotaxonomic markers. Modern pharmacology studies and clinical practice demonstrated that Epimedium and its active compounds possess wide pharmacological actions, especially in strengthening yang, hormone regulation, anti-osteoporosis, immunological function modulation, anti-oxidation and anti-tumor, anti-aging, anti-atherosclerosis and anti-depressant activities. Currently, effective monomeric compounds or active parts have been screened for pharmacological activity from Epimedium in vivo and in vitro. [Copyright &y& Elsevier]

Abstract: In this paper, microdialysis combined with ultra performance liquid chromatography/mass spectrometry (UPLC-MS) was applied for the determination of ligustilide in freely moving rats'' brain. The extracellular unbound ligustilide could be detected in rat brain within the first time interval (0–20min) after nasal administration but not after oral administration. This result showed that ligustilide could quickly enter the brain after nasal administration; which implied that ligustilide may have a rapid onset of action. This work demonstrated the potential application of microdialysis combined with UPLC-MS in pharmacokinetic studies. Furthermore, the advantage that fewer animals used in the microdialysis experiment was confirmed. [Copyright &y& Elsevier]

Abstract: Aim of the study: Lizhong Pill, composed of Radix Ginseng (Panax ginseng C.A. Meyer), Rhizoma Zingiberis (Zingiber officinale Roscoe), Rhizoma Atractylodis Macrocephalae (Atractylodes macrocephala Koidz.) and Radix Glycytthizae (Glycyrrhiza uralensis Fisch.), is a classical herbal product for curing spleen deficiency in traditional Chinese medicine (TCM), and reserpine treated rats show similar signs to TCM spleen deficiency pattern. This paper is aimed to explore the regulatory effect on neuroendocrinoimmune network by Lizhong Pill in reserpine induced TCM spleen deficiency rats. Materials and methods: 100 healthy adult male SD rats, with a mean weight of 200g, were randomly divided into five groups in average: control group, reserpine treated group, atropine treated group, treatment groups with Lizhong Pill at high dose and low dose (equal to the dosage of crude drugs for 4g/kg/d and 8g/kg/d). Rats in reserpine treated group were induced by intraperitoneal injection of reserpine at 0.5mg/kgd for 4 weeks. The levels of IL-1, IL-6 and gastrin were measured with radioimmunoassay, TNF-α and IFN-γ in serum were measured with ELISA, the level of vasoactive intestinal peptide (VIP) and substance P (SP) in small intestine were determined with radioimmunoassay, and the TNF-α and TGF-β positive cells in small intestine were detected by immunohistological staining. Data were analyzed with SAS 9.1 software package. Results: The rats in reserpine treated group, body weight, concentrations of IFN-γ, IL-1 and TNF-α in serum, expression of TGF-β in small intestine, VIP in small intestine decreased (P <0.05), and the level of IL-6 in serum, expression of TNF-α, SP in small intestine and gastrin were increased (P <0.05). Administration of Lizhong Pill at high dose could increase the body weights at day 21, and the weights of rats in Lizhong Pill groups were much higher compared to reserpine treated group. At high dose of Lizhong Pill could increase the level of TNF-α in serum. Lizhong Pill at high dose and low dose could reverse the changes of IL-1, IL-6 and IFN-γ, gastrin, expression of TGF-β and TNF-α, VIP and SP in small intestine. Conclusions: The rats treated with reserpine, with similar signs to TCM spleen deficiency, show neuroendocrinoimmune disorders, and the restoration of the neuroendocrinoimmune disorders might be the part of mechanism of Lizhong Pill for reinforcing TCM spleen deficiency.

Abstract: Tripterygium Glycosides (TG) is effective in the treatment of patients with a variety of inflammatory and autoimmune diseases, especially rheumatoid arthritis (RA) in clinical. Wilforlide A (T1) serves as a quality control standard of TG that be listed in Drug Standard of Ministry of Public Health of the People''s Republic of China. The pharmacologic actions of T1 remain to be unidentified. In this paper, we studied the anti-inflammatory and immune suppressive effect of T1, and compared it with Triptolide (TP), which believed to be the major active component of TG. Carrageenan-induced rat pedal swelling, tampon-induced rat granulation, and mice ear inhibition rate of swelling trail results show that high-dose T1 has obvious anti-inflammatory effect. Colorimetric detection contents of hemolysin, carbon elimination from plasma of mice, mice delayed hypersensitivity immune, and organ index were measured. The results show that T1 has no significant immune suppressive activity, and there has a significant difference with TP and TG. Therefore, we think the content of TP also should be controlled as a supplement standard in order to ensure safe and effective medication. [Copyright &y& Elsevier]

Ethnopharmacological relevance: Uncaria species (Gouteng in Chinese) have been used as ethnopharmacological medicines to treat ailments of the cardiovascular and central nervous systems. As the main alkaloid constituent of Uncaria species, rhynchophylline has drawn extensive attention in recent years for its antihypertensive and neuroprotective activities, and its pharmacological effects are related to ethnopharmacological medicine properties of Uncaria species. Aim of the review: This review examined the pharmacological studies and mechanisms of rhynchophylline, with an emphasis on cardiovascular and central nervous system diseases linked to the ethnopharmacological uses of Uncaria species. Methods: We conducted both an electronic search and a library search of in vivo and in vitro studies. The terms and keywords for the search included rhynchophylline, Uncaria species, Gouteng, pharmacological effects, and mechanism. We focused on the papers, including ours, with studies on all related pharmacological effects and mechanisms of rhynchophylline. Results: Rhynchophylline was the main constituent of several components identified from Uncaria species. Rhynchophylline mainly acts on cardiovascular and central nervous system diseases, including hypertension, bradycardia, arrhythmia, sedation, vascular dementia, epileptic seizures, drug addiction, and cerebral ischemia. Rhynchophylline also has effects on anticoagulation, inhibits vascular smooth muscle cell proliferation, and has been shown to be anti-endotoxemic. The active mechanisms are related to modulation of calcium and potassium ion channels, protection of neural and neuroglial cells, and regulation of central neurotransmitter transport and metabolism. More studies are necessary to verify the pharmacological activities and determine the exact mechanisms of rhynchophylline activity. Conclusions: Rhynchophylline treatment of cardiovascular and central nervous system diseases has a strong linkage with traditional concepts and uses of Uncaria species in ethnopharmacological medicine, such as treatment for lightheadedness, convulsions, numbness, and hypertension. As a candidate drug for several cardiovascular and central nervous system diseases, rhynchophylline will attract scientists to pursue the potential pharmacological effects and mechanisms with new technologies. Relatively few clinically relevant studies of rhynchophylline have been conducted. Thus, more in vivo validations and investigations of antihypertensive and neuroprotective mechanisms of rhynchophylline are necessary. [Copyright &y& Elsevier]

Abstract: Acanthopanax senticosus grows in many provinces in china and has long been used as a traditional medicine in china. This paper reports on the extraction of polysaccharides from A. senticosus and its effect of irradiation-protection. 15 Gy X-rays irradiation was delivered to rats. Polysaccharides from A. senticosus were administered before and after irradiation to examine its inhibition against irradiation-induced injury. Results indicate that in comparison with non-irradiated controls, irradiation of 15 Gy resulted in a significant reduction of rats’ body weight (BW), food and water intake, white cell counts (WC), activity of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and increase of MDA level 10–20 days after being irradiated although after that these indexes start to slowly return to normal (p <0.05, p <0.01). Oral administration of polysaccharides from A. senticosus dose-dependently reduced the irradiation-induced injury on rats studied, showed a protective effect against irradiation-induced loss of BW, WC, food and water intake, reduce MDA level and raise antioxidase activity (SOD, GSH-Px) (p <0.05, p <0.01). It may be concluded that polysaccharides from A. senticosus possess good irradiation-protective effect. [Copyright &y& Elsevier]

This paper focuses on the question of why the social and political acceptance of Chinese medicine has grown in the former British colony of Hong Kong since the late 1980s. To supplement the conventional explanations for the institutionalization of alternative medicines, we propose a political process perspective that highlights the effects of political changes amidst the decolonization process in Hong Kong. During the late 1980s and early 1990s, the weakening of the political position of the established elite, the opening up of political space for previously excluded groups, and the competition for support among the new political elite, all stimulated the indigenous Chinese medicine organizations to mobilize for the institutionalization of Chinese medicine. By the mid-1990s academics from leading tertiary institutions began to take over the leadership of the movement and in doing so carried it to a higher level. In the conclusion, we briefly consider the implications of this movement for the future development of alternative medicine in Hong Kong and other societies. [ABSTRACT FROM AUTHOR]

Background Advanced lung cancer presents an upward trend mortality rates that need maintains treatment concurrent with chemotherapy or target therapy. Recently, complementary and alternative medicine (CAM) is considered and used as maintains treatment, special herbal medicines. In this paper, we reported the improvement of quality of life (QOL) in advanced lung cancer by herbal medicines. Methods: 83 advanced non-small cell lung cancer patients, who were failure with first-line treatment or refused receiving chemotherapy, reported using herbal extractive medicines based complementary and alternative medicine. Senghuang capsule (SH) and Xianhe Baijiang capsule (XB), which consist of ginseng, astragalus, herba agrimoniae and herba patriniae etc, have been approved by the China Food and Drug Administration (CFDA). Meanwhile, hyperthermia and arginine were also initiated. NRS pain, NRS2002 nutrition and ECOG score, which associated with QOL, were used to evaluate the effectiveness of CAM treatment. The results were analyzed by SPSS16.0 in t-test. RESULTS: After fifteen days treatment, 67.86%, 47.44% and 54.22% of patients' pain, nutrition status and QOL were improved, respectively. In detail, NRS pain, NRS2002 nutrition and ECOG score dropped to 2.4 ± 1.8, 2.0 ± 1.5 and 2.4 ± 1.0 compared to 4.0 ± 1.5, 2.8 ± 1.6 and 2.8 ± 0.7 (P value < 0.05), respectively. No severe hematology and digestion side-effects were observed. Conclusion: Use of herbal preparations as complementary and alternative medicine can improve the quality of life and provide moderate effectiveness in advanced lung cancer. [ABSTRACT FROM AUTHOR]
