Abstract
Exosomes, small yet vital extracellular vesicles, play an integral role in intercellular communication. They transport critical components, such as proteins, lipid bilayers, DNA, RNA, and glycans, to target cells. These vesicles are crucial in modulating the extracellular matrix and orchestrating signal transduction processes. In oncology, exosomes are pivotal in tumor growth, metastasis, drug resistance, and immune modulation within the tumor microenvironment. Exosomal proteins, noted for their stability and specificity, have garnered widespread attention. This review delves into the mechanisms of exosomal protein loading and their impact on tumor development, with a focus on the regulatory effects of natural products and traditional Chinese medicine on exosomal protein loading and function. These insights not only offer new strategies and methodologies for cancer treatment but also provide scientific bases and directions for future clinical applications.

Berberine for gastric cancer prevention and treatment: Multi-step actions on the Correa's cascade underlie its therapeutic effects. Pharmacol Res 2022; 184:106440.

Abstract
Gastric carcinoma (GC) is a complex multifactorial disease occurring as sequential events commonly referred to as the Correa's cascade, a stepwise progression from non-active or chronic active gastritis, to gastric precancerous lesions, and finally, adenocarcinoma. Therefore, the identification of novel agents with multi-step actions on the Correa's cascade and those functioning as multiple phenotypic regulators are the future direction for drug discovery. Recently, berberine (BBR) has gained traction owing to its pharmacological properties, including anti-inflammatory, anti-cancer, anti-ulcer, antibacterial, and immunopotentiation activities. In this article, we investigated and summarized the multi-step actions of BBR on Correa's cascade and its underlying regulatory mechanism in gastric carcinogenesis for the first time, along with a discussion on the strength of BBR to prevent and treat GC. BBR was found to suppress H. pylori infection, control mucosal inflammation, and promote ulcer healing. In the gastric precancerous lesion phase, BBR could reverse mucosal atrophy and prevent lesions in intestinal metaplasia and dysplasia by regulating inflammatory cytokines, promoting cell apoptosis, regulating macrophage polarization, and regulating autophagy. Additionally, the therapeutic action of BBR on GC was partly realized through the inhibition of cell proliferation, migration, and angiogenesis; induction of apoptosis and autophagy, and enhancement of chemotherapeutic drug sensitivity. BBR exerted multi-step actions on the Correa's cascade, thereby halting and even reversing gastric carcinogenesis in some cases. Thus, BBR could be used to prevent and treat GC. In conclusion, the therapeutic strategy underlying BBR's multi-step action in the trilogy of Correa's cascade may include "prevention of gastric mucosal inflammation (Phase 1); reversal of gastric precancerous lesions (Phase 2), and rescue of GC (Phase 3)". The NF-κB, PI3K/Akt, and MAPK signaling pathways may be the key signaling transduction pathways underlying the treatment of gastric carcinogenesis using BBR. The advantage of BBR over conventional drugs is its multifaceted and long-term effects. This review is expected to provide preclinical evidence for using BBR to prevent gastric carcinogenesis and treat gastric cancer.

Abstract
As novel non-coding RNAs (ncRNAs), circular RNAs (circRNAs) play an essential role in the pathogenesis of many chronic diseases, and the regulation of these functional molecules has become a research hotspot gradually. Within the past decade, phytochemicals were reported to regulate the expression of long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) in various chronic diseases, and more recently, most studies focus on the regulatory roles of phytochemicals on circRNAs. Abnormal expression of circRNAs has been identified in chronic diseases like cancer, heart failure, depression and atherosclerosis, and numerous studies have revealed the modulation of circRNAs by phytochemicals including berberine, celastrol, cinnamaldehyde, curcumin, et al. The expression of circRNAs, such as circSATB2 and circFOXM1, were modulated by phytochemicals, and these regulations further affected cell proliferation, apoptosis, migration, invasion, autophagy, chemosensitivity, radiosensitivity and other biological processes. Mechanismly, the circRNAs mainly functioned as miRNA sponge, subsequently affecting miRNA-mediated regulation of target genes and related cell signaling pathways. In this review, we summarized the impact of phytochemicals on circRNAs expression and biological function, and discussed the mechanisms underlying phytochemicals regulating circRNAs in cancer and other chronic diseases.

Abstract
As an effective drug against acute enteritis diarrhea, Gegen Qinlian decoction (GQD) has a history of 2000 years. However, the potential molecular mechanism through which GQD could protect intestinal barrier from ulcerative colitis (UC) still remains undefined. As an important part of the homeostasis of the colon, gut microbiota is closely related to the dynamic evolution of the surrounding environment and the adjustment of dietary structure. At present, the effectiveness and mechanism of Jiawei Gegen Qinlian decoction against UC in different dietary environments are not clear. Here, the main active components of Jiawei Gegen Qinlian Decoction (PBM), were selected to construct a reasonable and effective compound scheme. We adopted "5% dextran sulfate sodium (DSS)" and "high temperature and humidity + high sugar and high fat + alcohol + 5%DSS" to induce UC rat models in general environment and UC rat models in Lingnan area, respectively. Then, we examined the therapeutic effects of PBM (89.96 mg/kg and 179.92 mg/kg) on two kinds of UC rats. The role of gut microbiota in the anti-UC effect of PBM was identified by intestinal flora consumption and fecal microbiota transplantation (FMT) experiments. Subsequently, we monitored the alterations of gut microbiota and fecal metabolism in the rat colon by 16Sr DNA technique and targeted metabonomics, respectively. The colon inflammation of the PBM-treated and the FMT-treated rats both showed significant relief, as evidenced by a reduction in body weight loss, bloody stool, diarrhea, disease activity index (DAI) score, shortening of colon length as well as decreased colon histology damage. Interestingly enough, the depletion of intestinal flora took away the protective effect of PBM, confirming the importance of intestinal flora in the anti-UC effect of PBM. Then our findings suggested that PBM could not only regulate the gut microbiota by increasing Akkermansia and Romboutsia but also decrease Escherichia-Shigella. More importantly, PBM could increase the production of propionate and total short-chain fatty acids (SCFAs) in colitis rats, regulate medium and long chain fatty acids (M-LCFAs), maintain bile acids (BAs) homeostasis, and regulate amino acids (AAs) metabolism. The transformation of intestinal environment might be related to the upregulation of anti-inflammation, anti-oxidation and tight junction protein expression in colonic mucosa. In summary, PBM showed potential for anti-UC activity through gut microbiota dependence and was expected to be a complementary and alternative medicine herb therapy.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory intestinal disorder that is difficult to cure and characterized by periods of relapse. To face the challenges of limited treatment strategies and drawbacks of conventional medications, developing new and promising strategies as well as safe and effective drugs for treatment of IBD has become an urgent demand for clinics. The imbalance of Th17/Treg is a crucial event for the development of IBD, and studies have verified that correcting the imbalance of Th17/Treg is an effective strategy for preventing and treating IBD. Recently, a growing body of studies has indicated that phytochemicals derived from natural products are potent regulators of Th17/Treg, and exert preferable protective benefits against colonic inflammation. In this review, the great potential of anti-colitis agents derived from natural products through targeting Th17/Treg cells and their action mechanisms for the treatment or prevention of IBD in recent research is summarized, which may help further the development of new drugs for IBD treatment.

Abstract
Metabolic reprogramming, characterized by alterations of cellular metabolic patterns, is fundamentally important in supporting the malignant behaviors of cancer cells. It is considered as a promising therapeutic target against cancer. Traditional Chinese medicine (TCM) and its bioactive components have been used in cancer therapy for an extended period, and they are well-known for their multi-target pharmacological functions and fewer side effects. However, the detailed and advanced mechanisms underlying the anticancer activities of TCM remain obscure. In this review, we summarized the critical processes of cancer cell metabolic reprogramming, including glycolysis, mitochondrial oxidative phosphorylation, glutaminolysis, and fatty acid biosynthesis. Moreover, we systemically reviewed the regulatory effects of TCM and its bioactive ingredients on metabolic enzymes and/or signal pathways that may impede cancer progress. A total of 46 kinds of TCMs was reported to exert antitumor effects and/or act as chemosensitizers via regulating metabolic processes of cancer cells, and multiple targets and signaling pathways were revealed to contribute to the metabolic-modulating functions of TCM. In conclusion, TCM has its advantages in ameliorating cancer cell metabolic reprogramming by its poly-pharmacological actions. This review may shed some new light on the explicit recognition of the mechanisms of anticancer actions of TCM, leading to the development of natural antitumor drugs based on reshaping cancer cell metabolism.

Abstract
Recently non-alcoholic fatty liver disease (NAFLD) has grabbed considerable scientific attention, owing to its rapid increase in prevalence worldwide and growing burden on end-stage liver diseases. Metabolic syndrome including obesity, diabetes, and hypertension poses a grave risk to NAFLD etiology and progression. With no drugs available, the mainstay of NAFLD management remains lifestyle changes with exercise and dietary modifications. Nonselective drugs such as metformin, thiazolidinediones (TZDs), ursodeoxycholic acid (UDCA), silymarin, etc., are also being used to target the interrelated pathways for treating NAFLD. Considering the enormous disease burden and the unmet need for drugs, fresh insights into pathogenesis and drug discovery are required. The emergence of the field of epigenetics offers a convincing explanation for the basis of lifestyle, environmental, and other risk factors to influence NAFLD pathogenesis. Therefore, understanding these epigenetic modifications to target the primary cause of the disease might prove a rational strategy to prevent the disease and develop novel therapeutic interventions. Apart from describing the role of epigenetics in the pathogenesis of NAFLD as in other reviews, this review additionally provides an elaborate discussion on exploiting the high plasticity of epigenetic modifications in response to environmental cues, for developing novel therapeutics for NAFLD. Besides, this extensive review provides evidence for epigenetic mechanisms utilized by several potential drugs for NAFLD.

Abstract
The gut microbiota is recognized as a promising therapeutic target for anxiety. Berberine (BBR) has shown efficacy in the treatment of diseases such as postmenopausal osteoporosis, obesity, and type 2 diabetes through regulating the gut microbiota. However, the effects of BBR on postmenopausal anxiety are still unclear. The purpose of the study is to test whether BBR ameliorates anxiety by modulating intestinal microbiota under estrogen-deficient conditions. Experimental anxiety was established in specific pathogen-free (SPF) ovariectomized (OVX) rats, which were then treated with BBR for 4 weeks before undergoing behavioral tests. Open field and elevated plus maze tests demonstrated that BBR treatment significantly ameliorated anxiety-like behaviors of OVX rats compared with vehicle-treated counterparts. Moreover, as demonstrated by 16S rRNA sequencing and liquid chromatography/mass spectrometry (LC/MS) analysis, BBR-treated OVX rats harbored a higher abundance of beneficial gut microbes, such as Bacteroides, Bifidobacterium, Lactobacillus, and Akkermansia, and exhibited increased equol generation. Notably, gavage feeding of BBR had no significant anti-anxiety effects on germ-free (GF) rats that underwent ovariectomy, whereas GF rats transplanted with fecal microbiota from SPF rats substantially phenocopied the donor rats in terms of anxiety-like symptoms and isoflavone levels. This study indicates that the gut microbiota is critical in the treatment of ovariectomy-aggravated anxiety, and that BBR modulation of the gut microbiota is a promising therapeutic strategy for treating postmenopausal symptoms of anxiety.

Abstract
Cerebral ischemia reperfusion injury (CIRI), one of the major causes of death from stroke in the world, not only causes tremendous damage to human health, but also brings heavy economic burden to society. Current available treatments for CIRI, including mechanical therapies and drug therapies, are often accompanied by significant side-effects. Therefore, it is necessary to discovery new strategies for treating CIRI. Many studies have confirmed that the herbal medicine has the advantages of abundant resources, good curative effect and little side effects, which can be used as potential drug for treatment of CIRI through multiple targets. It's known that oral administration commonly has low bioavailability, and injection administration is inconvenient and unsafe. Many drugs can't delivery to brain through routine pathways due to the blood-brain-barrier (BBB). Interestingly, increasing evidences have suggested the nasal administration is a potential direct route to transport drug into brain avoiding the BBB and has the characteristics of high bioavailability for treating brain diseases. Therefore, intranasal administration can be treated as an alternative way to treat brain diseases. In the present review, effective methods to treat CIRI by using active ingredients derived from herbal medicine through nose to brain drug delivery (NBDD) are updated and discussed, and some related pharmacological mechanisms have also been emphasized. Our present study would be beneficial for the further drug development of natural agents from herbal medicines via NBDD.

Abstract
Human antigen R (HuR), also known as HuA and embryonic lethal abnormal vision-like 1 (ELAVL1), is a ubiquitously expressed RNA binding protein and functions as an RNA regulator and mediates the expression of various proteins by diverse post-transcriptional mechanisms. HuR has been well characterized in the inflammatory responses and in the development of various cancers. The importance of HuR-mediated roles in cell signaling, inflammation, fibrogenesis and cancer development in the liver has attracted a great deal of attention. However, there is still a substantial gap between the current understanding of the potential roles of HuR in the progression of liver disease and whether HuR can be targeted for the treatment of liver diseases. In this review, we introduce the function and mechanistic characterization of HuR, and then focus on the physiopathological roles of HuR in the development of different liver diseases, including hepatic inflammation, alcoholic liver diseases, non-alcoholic fatty liver diseases, viral hepatitis, liver fibrosis and liver cancers. We also summarize existing approaches targeting HuR function. In conclusion, although characterizing the liver-specific HuR function and demonstrating the multi-level regulative networks of HuR in the liver are still required, emerging evidence supports the notion that HuR represents a potential therapeutic target for the treatment of chronic liver diseases.

Abstract
Ischemia-reperfusion (I/R) injury is accompanied with high morbidity and mortality and has seriously negative social and economic influences. Unfortunately, few effective therapeutic strategies are available to improve its outcome. Berberine is a natural medicine possessing multiple beneficial biological activities. Emerging evidence indicates that berberine has potential protective effects against I/R injury in brain, heart, kidney, liver, intestine and testis. However, up-to-date review focusing on the beneficial role of berberine against I/R injury is not yet available. In this paper, results from animal models and clinical studies are concisely presented and its mechanisms are discussed. We found that berberine ameliorates I/R injury in animal models via its anti-oxidant, anti-apoptotic and anti-inflammatory effects. Moreover, berberine also attenuates I/R injury by suppressing endoplasmic reticulum stress and promoting autophagy. Additionally, regulation of periphery immune system may also contributes to the beneficial effect of berberine against I/R injury. Although clinical evidence is limited, the current studies indicate that berberine may attenuate I/R injury via inhibiting excessive inflammatory response in patients. Collectively, berberine might be used as an alternative therapeutic strategy for the management of I/R injury.

Abstract
The dynamic and delicate interactions amongst intestinal microbiota, metabolome and metabolism dictates human health and disease. In recent years, our understanding of gut microbial regulation of intestinal immunometabolic and redox homeostasis have evolved mainly out of in vivo studies associated with high-fat feeding induced metabolic diseases. Techniques utilizing fecal transplantation and germ-free mice have been instrumental in reproducibly demonstrating how the gut microbiota affects disease pathogenesis. However, the pillars of modern drug discovery i.e. evidence-based pharmacological studies critically lack focus on intestinal microflora. This is primarily due to targeted in vitro molecular-approaches at cellular-level that largely overlook the etiology of disease pathogenesis from the physiological perspective. Thus, this review aims to provide a comprehensive understanding of the key notions of intestinal microbiota and dysbiosis, and highlight the microbiota-phytochemical bidirectional interactions that affects bioavailability and bioactivity of parent phytochemicals and their metabolites. Potentially by focusing on the three major aspects of gut microbiota i.e. microbial abundance, diversity, and functions, I will discuss phytochemical-microbiota reciprocal interactions, biotransformation of phytochemicals and plant-derived drugs, and pre-clinical and clinical efficacies of herbal medicine on dysbiosis. Additionally, in relation to phytochemical pharmacology, I will briefly discuss the role of dietary-patterns associated with changes in microbial profiles and review pharmacological study models considering possible microbial effects. This review therefore, emphasize on the timely and critically needed evidence-based phytochemical studies focusing on gut microbiota and will provide newer insights for future pre-clinical and clinical phytopharmacological interventions.

Abstract
As an important component of complementary and alternative medicines, traditional Chinese medicines (TCM) are gaining more and more attentions around the world because of the powerful therapeutic effects and less side effects. However, there are still some doubts about TCM because of the questionable TCM theories and unclear biological active compounds. In recent years, gut microbiota has emerged as an important frontier to understand the development and progress of diseases. Together with this trend, an increasing number of studies have indicated that drug molecules can interact with gut microbiota after oral administration. In this context, more and more studies pertaining to TCM have paid attention to gut microbiota and have yield rich information for understanding TCM. After oral administration, TCM can interact with gut microbiota: (1) TCM can modulate the composition of gut microbiota; (2) TCM can modulate the metabolism of gut microbiota; (3) gut microbiota can transform TCM compounds. During the interactions, two types of metabolites can be produced: gut microbiota metabolites (of food and host origin) and gut microbiota transformed TCM compounds. In this review, we summarized the interactions between TCM and gut microbiota, and the pharmacological effects and features of metabolites produced during interactions between TCM and gut microbiota. Then, focusing on gut microbiota and metabolites, we summarized the aspects in which gut microbiota has facilitated our understanding of TCM. At the end of this review, the outlooks for further research of TCM and gut microbiota were also discussed.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sanmiao Wan (SMW) has been a basic prescription employed for the treatment for gout in the clinic since Yuan dynasty. Achyranthis bidentatae radix (ABR) is designed as a lower-guiding drug in SMW to augment the articular accumulation of active ingredients and improve the anti-inflammatory effect. AIM OF THE STUDY Present study was undertaken to investigate the dose-response relationship of berberine in SMW between the articular concentration and anti-inflammatory effect in the knee joint under the lower-guiding of ABR. MATERIALS AND METHODS Rats were divided into control group, model group and SMW without or with low, medium and high doses of ABR groups. Rat model of acute gouty arthritis (AGA) was established by intra-articular injection of 0.2 mL monosodium urate crystal (20 mg/mL) inside knee joint cavity on day 2 during drug treatment slots. Knee joint swelling, synovial hyperplasia and inflammatory cell infiltration were investigated for anti-inflammatory study. The concentrations of berberine in rat plasma and tissues were determined by UPLC-MS/MS method. The effect of ABR on the expression levels of P-glycoprotein (P-gp) and MDR1 mRNA in the synovial tissues of knee joints in AGA rats was examined by Western blot and RT-qPCR assay, respectively. RESULTS The distribution of berberine increased by 6.53%, 44.31% and 212.96% in the knee joint and 474.93%, 631.01% and 1063.3% in the ankle for SMW with low, medium and high doses of ABR groups, compared with SMW without ABR group. Similarly, the plasma level of berberine increased by 19.81%, 143.4% and 681.13%. On the contrary, the distribution of berberine evidently decreased 3.23, 10.61 and 46.21-fold in heart and 3.68, 6.74 and 24.78-fold in lung. SMW with different doses of ABR groups exhibited better efficiency than SMW without ABR group on ameliorating knee joint swelling, inhibiting synovial hyperplasia and alleviating inflammatory cell infiltration of AGA rats. The treatment with ABR could down-regulate the MDR1 mRNA and P-gp expressions of synovial tissues of knee joints in AGA rats. CONCLUSIONS The enhanced articular distribution of berberine in SMW was attributed to the lower-guiding effect of ABR, which could evidently increase the plasma concentration of berberine, improve the supply of blood of inflamed joint, reduce the distribution of berberine in heart and lung and significantly inhibit the MDR1 mRNA and P-gp expression of synovial tissues of knee joints in AGA rats. The dose-response relationship of berberine between the enhanced articular concentration and improved anti-inflammatory effect in the knee joint under the lower-guiding of ABR was observed for the first time.

Abstract
ETHNOBOTANICAL RELEVANCE Malaria is a serious public health problem especially in sub-Saharan African countries such as Nigeria. The causative parasite is increasingly developing resistance to the existing drugs. There is urgent need for alternative and affordable therapy from medicinal plants which have been used by the indigenous people for many years. AIM OF STUDY This study was conducted to document the medicinal plant species traditionally used by the people of Nsukka Local Government Area in south-eastern Nigeria for the treatment of malaria. METHODS A total of 213 respondents, represented by women (59.2%) and men (40.8%), were interviewed using a semi-structured questionnaire. The results were analysed and discussed in the context of previously published information on anti-malarial and phytochemical studies of the identified plants. RESULTS The survey revealed that 50 plant species belonging to 30 botanical families were used in this region for the treatment of malaria. The most cited families were Apocynaceae (13.3%), Annonaceae (10.0%), Asteraceae (10.0%), Lamiaceae (10.0%), Poaceae (10.0%), Rubiaceae (10.0%) and Rutaceae (10.0%). The most cited plant species were Azadirachta indica (11.3%), Mangifera indica (9.1%), Carica papaya (8.5%), Cymbopogon citratus (8.5%) and Psidium guajava (8.5%). CONCLUSION The present findings showed that the people of Nsukka use a large variety of plants for the treatment of malaria. The identified plants are currently undergoing screening for anti-malarial, toxicity and chemical studies in our laboratory.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Alzheimer's disease (AD), a deleterious neurodegenerative disorder that impairs memory, cognitive functions and may lead to dementia in late stage of life. The pathogenic cause of AD remains incompletely understood and FDA approved drugs are partial inhibitors rather than curative. Most of drugs are synthetic or natural products as galanthamine is an alkaloid obtained from Galanthus spp. Huperzine A, an alkaloid found in Huperzia spp., gingkolides a diterpenoids from Gingko biloba and many ethnobotanicals like Withania somnifera (L.) Dunal., Physostigma venenosum Balf., Bacopa monnieri (L.) Wettst., Centella asiatica (L.) Urb. have been used by traditional Indian, Chinese, and European system of medicines in AD. Clinical significance opioid alkaloid in Papaver somniferum has shown another dimension to this study. Over exploitation of medicinal plants with limited bioactive principles has provided templates to design synthetic drugs in AD e.g. rivastigmine, phenserine, eptastigmine based on chemical structure of physostigmine of Physostigma venenosum Balf. Even ZT-1 a prodrug of Hup A and memogain a prodrug of galantamine has achieved new direction in drug development in AD. All these first-line cholinesterase-inhibitors are used as symptomatic treatments in AD. Single modality of "One-molecule-one-target" strategy for treating AD has failed and so future therapies on "Combination-drugs-multi-targets" strategy (CDMT) will need to address multiple aspects to block the progression of pathogenesis of AD. Besides, cholinergic and amyloid drugs, in this article we summarize proteinopathy-based drugs as AD therapeutics from a variety of biological sources. In this review, an attempt has been made to elucidate the molecular mode of action of various plant products, and synthetic drugs investigated in various preclinical and clinical tests in AD. It also discusses current attempts to formulate a comprehensive CDMT strategy to counter complex pathogenesis in AD. MATERIALS AND METHODS Information were collected from classical books on medicinal plants, pharmacopoeias and scientific databases like PubMed, Scopus, GoogleScholar, Web of Science and electronic searches were performed using Cochrane Library, Medline and EMBASE. Also published scientific literatures from Elsevier, Taylor and Francis, Springer, ACS, Wiley publishers and reports by government bodies and documentations were assessed. RESULTS 60 no. of natural and synthetic drugs have been studied with their significant bioactivities. A decision matrix designed for evaluation of drugs for considering to the hypothetic "CDMT" strategy in AD. We have introduced the scoring pattern of individual drugs and based on scoring pattern, drugs that fall within the scoring range of 18-25 are considered in the proposed CDMT. It also highlights the importance of available natural products and in future those drugs may be considered in CDMT along with the qualified synthetic drugs. CONCLUSION A successful validation of the CDMT strategy may open up a debate on health care reform to explore other possibilities of combination therapy. In doing so, it should focus on clinical and molecular relationships between AD and CDMT. A better understanding of these relationships could inform and impact future development of AD-directed treatment strategies. This strategy also involves in reducing costs in treatment phases which will be affordable to a common man suffering from AD.

Abstract
Inflammation is one of the major causative factor of cancer and chronic inflammation is involved in all the major steps of cancer initiation, progression metastasis and drug resistance. The molecular mechanism of inflammation driven cancer is the complex interplay between oncogenic and tumor suppressive transcription factors which include FOXM1, NF-kB, STAT3, Wnt/β- Catenin, HIF-1α, NRF2, androgen and estrogen receptors. Several products derived from natural sources modulate the expression and activity of multiple transcription factors in various tumor models as evident from studies conducted in cell lines, pre-clinical models and clinical samples. Further combination of these natural products along with currently approved cancer therapies added an additional advantage and they considered as promising targets for prevention and treatment of inflammation and cancer. In this review we discuss the application of multi-targeting natural products by analyzing the literature and future directions for their plausible applications in drug discovery.

Abstract
ETHNOPHARMACOLOGIC RELEVANCE Berberine (BBR) is a naturally occurring alkaloid compound that can be found in Chinese medicinal herbs such as Rhizoma Coptidis and Phellodendri Cortex. These BBR containing herbs are commonly used by Chinese medicine doctors to treat cancers including melanoma. In this study, we explored proteins potentially involved in the anti-melanoma effects of BBR using computational and experimental approaches. MATERIALS AND METHODS Target proteins of BBR were predicted using the reverse pharmacophore screening, molecular docking and molecular dynamics. Anti-melanoma activities of BBR in melanoma cells were examined by MTT and EdU proliferation assays. Effects of BBR on activities of target proteins in melanoma cells were examined by Western blotting or fluorescence assay. RESULTS Ten proteins implicated in cancer and with high fit-score in the reverse pharmacophore screening were selected as potential targets of BBR. Molecular docking and molecular dynamics revealed that BBR could stably bind to four of the ten proteins, namely 3-phosphoinositide-dependent protein kinase 1 (PDK1), glucocorticoid receptor (GR), p38 mitogen-activated protein kinase (p38) and dihydroorotate dehydrogenase (DHODH). Cellular experiments showed that BBR inhibited cell proliferation, increased the phosphorylation of GR and p38, and inhibited the activity of DHODH in A375 human melanoma cells. CONCLUSIONS These findings suggest that p38, GR and DHODH are potentially involved in the anti-melanoma action of BBR. This study provided a chemical and pharmacological justification for the clinical use of BBR-containing herbs in melanoma treatment.

Abstract
In our previous study, Rhizoma Coptidis extract was found to exert more potent inhibitory effect than its major component berberine towards urease from Helicobacter pylori (HPU) and jack bean (JBU). In continuation of our work, the present study was designed to further comparatively investigate the urease inhibitory activities of five major protoberberine alkaloids in Rhizoma Coptidis, namely berberine, palmatine, coptisine, epiberberine, jateorhizine to identify the bioactive constituent, and illuminate the potential mechanism of action. Results indicated that the five protoberberine alkaloids acted as concentration-dependent inactivators of urease with IC50 values ranging between 3.0 and 5087μM for HPU and 2.3->10,000μM for JBU, respectively. Notably, epiberberine (EB) was found to be the most potent inhibitor against both ureases with IC50 values of 3.0±0.01μM for HPU and 2.3±0.01μM for JBU, which was more effective than the standard urease inhibitor, acetohydroxamic acid (83±0.01μM for HPU and 22±0.01μM for JBU, respectively). Further kinetic analysis revealed that the type of EB inhibition against HPU was slow-binding and uncompetitive, with Ki of 10.6±0.01μM, while slow-binding and competitive against JBU with Ki of 4.6±0.01μM. Addition of thiol reagents, such as l-cysteine, glutathione and dithiothreitol, significantly abolished the inhibition, while Ni2+ competitive inhibitors, boric acid and sodium fluoride, synergetically inhibited urease with EB, indicating the obligatory role of the active site sulfhydryl group for the inhibition. In addition, binding of EB with the urease proved to be reversible, as about 65% and 90% enzymatic activity of HPU and JBU, respectively, could be restored by dithiothreitol application. These findings highlighted the potential role of Rhizoma Coptidis protoberberine alkaloids, especially EB, as a lead urease inhibitor in the treatment of diseases associated with ureolytic bacteria. Thus, EB had good potential for further development into a promising therapeutic approach for the treatment of urease-related diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Alzheimer's disease (AD), as the most common type of dementia, has brought a heavy economic burden to healthcare system around the world. However, currently there is still lack of effective treatment for AD patients. Herbal medicines, featured as multiple herbs, ingredients and targets, have accumulated a great deal of valuable experience in treating AD although the exact molecular mechanisms are still unclear. MATERIALS AND METHODS In this investigation, we proposed a network pharmacology-based method, which combined large-scale text-mining, drug-likeness filtering, target prediction and network analysis to decipher the mechanisms of action for the most widely studied medicinal herbs in AD treatment. RESULTS The text mining of PubMed resulted in 10 herbs exhibiting significant correlations with AD. Subsequently, after drug-likeness filtering, 1016 compounds were remaining for 10 herbs, followed by structure clustering to sum up chemical scaffolds of herb ingredients. Based on target prediction results performed by our in-house protocol named AlzhCPI, compound-target (C-T) and target-pathway (T-P) networks were constructed to decipher the mechanism of action for anti-AD herbs. CONCLUSIONS Overall, this approach provided a novel strategy to explore the mechanisms of herbal medicine from a holistic perspective.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine (TCM), an ancient yet still alive medicinal system widely used in East Asia, has played an essential role in health maintenance and diseases control, for a wide range of human chronic diseases like cancers and neurodegenerative diseases. TCM-derived compounds and extracts attract wide attention for their potential application as therapeutic agents against above mentioned diseases. AIM OF REVIEW Recent years the enthusiasm in searching for autophagy regulators for human diseases has yielded many positive hits. TCM-derived compounds as important sources for drug discovery have been widely tested in different models for autophagy modulation. Here we summarize the current progress in the discovery of natural autophagy regulators from TCM for the therapeutic application in cancer and neurodegenerative disease models, aiming to provide the direct link from traditional use to new pharmacological application. METHODS The present review collected the literature published during the recent 10 years which studied the effect of TCM-derived compounds or extracts on autophagy regulation from PubMed, Web of Science, Google Scholar and Science Direct. The names of chemical compounds studied in this article are corresponding to the information in journal plant list. RESULTS In this review, we give a brief introduction about the autophagy and its roles in cancer and neurodegenerative disease models and describe the molecular mechanisms of autophagy modulation. We also make comprehensive lists to summarize the effects and underlying mechanisms of TCM-derived autophagy regulators in cancer and neurodegenerative disease models. In the end of the review, we discuss the current strategies, problems and future direction for TCM-derived autophagy regulators in the treatment of human diseases. CONCLUSIONS A number of data from in vivo and in vitro models indicated TCM derived compounds and extracts hold great potential for the treatment of human diseases including cancers and neurodegenerative diseases. Autophagy, as a novel and promising drug target involved in a wide range of human diseases, can be modulated by many TCM derived agents, indicating autophagy modulation may be an important mechanism underlying the therapeutic effect of TCM in treating diseases. Furthermore, we look forward to seeing the discovery of ideal autophagy modulators from TCM with considerably higher selectivity for the treatment of human diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Reproductive healthcare has been highlighted as a major challenge in Lesotho mainly due to the high prevalence of HIV/AIDS and sexually transmitted infections. As a result other reproductive ailments have not received much attention, particularly because healthcare facilities are already limited and many of them are inaccessible. For these reasons, medicinal plants play a major role in primary healthcare system in the country, in addition the plants are easily accessible, more affordable, and their use forms part of the cultural heritage. However, documentation of medicinal plants used for reproductive ailments is scattered, more importantly the biological and pharmacological properties, as well as toxicity of many of these plants are not yet known. AIM OF THE STUDY To document the plants used by both male and female Basotho (residing in Lesotho) for the treatment of reproductive ailments, to explore their recorded biological and pharmacological effects as well as their toxicity, and to establish if these plants are used for similar purposes in other southern African cultures. MATERIALS AND METHODS The results stem from published findings of recent interviews of traditional medicinal practitioners in the Maseru District of Lesotho, first author's own experiences and observations from the Qacha's Nek District as well as comprehensive literature survey including numerous books and unpublished data. Electronic databases such as Google, Google Scholar, PubMed, and ScienceDirect were also used to search for the chemical compounds, pharmacological activity, and toxicity of the plants. RESULTS A total of 87 plant species are reported to be used for the treatment of several reproductive problems such as infertility, complications associated with pregnancy (twelve plants are used to treat conditions such as colic, heartburn, nausea, and constipation), cleansing and/ or toning of the uterus (with a purpose either to induce pregnancy or to get rid of the placenta, for example Withania somnifera and Zantedeschia albomaculata), difficult childbirth, as well treatment of breast and cervical cancer, cysts, fibroids, and testicular tumours (e.g. Hypoxis hemerocallidea). For the toning of the uterus, it is common to use a combination of plants, e.g. Gunnera perpensa, Scabiosa columbaria, and Eriospermum ornithogaloides. CONCLUSIONS Of the 87 plants used for reproductive healthcare, the highest number (31) is used for the treatment of infertility (in both men and women). The pharmacological effects, active compounds, and toxicology of many of these plants are not yet known.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zhikang Capsule (ZKC) is a traditional Chinese medicine (TCM) modified from classic formulas Qi-Li-San (an ancient formula dating to Qing Dynasty) and Fu-Jin-Sheng-Ji-San (written into The Golden Mirror of Medicine). ZKC contains 14 kinds of materials and has been widely used for the clinical therapy of inflammatory bowel diseases (IBD) for a long time. However, the therapeutic mechanisms of ZKC are still unclear. AIM OF THE STUDY To determine the protective effect of ZKC on dextran sodium sulfate (DSS)-induced colitis and explore the underlying mechanisms. MATERIALS AND METHODS C57BL/6 mice were fed with 3% DSS in drinking water for one week to induce experimental colitis. They were randomly assigned to six groups according to the treatment conditions. The histological changes of colon tissues were observed by hematoxylin and eosin (H&E) staining. The serum concentration of pro-inflammatory cytokines (TNF-α, IFN-γ, IL-1β, and IL-12) and anti-inflammatory mediators (IL-4 and IL-10) was detected by enzyme-linked immune sorbent assays (ELISAs). The production of MPO, SOD, MDA, NO, and caspase-3 was assessed by biochemical assay kits. The expression of iNOS, ICAM-1, and NF-ΚB was evaluated by immunohistochemistry staining. The levels of TLR4, MyD88, and TRAF6 were determined by western blot. RESULTS Histologic analysis exhibited that ZKC alleviated the inflammation, loss of goblet cells, and submucosal edema induced by DSS. ZKC significantly suppressed the pro-inflammatory cytokines and promoted the anti-inflammatory mediators. The antioxidation of ZKC was indicated by increased activity of SOD and reduced production of MDA, NO, and iNOS in ZKC-treated mice. Furthermore, ZKC repressed the colonic expression of caspase-3 and the activity of the MyD88-dependent TLR4 signaling pathway. CONCLUSIONS This research demonstrated the protective effect of ZKC on DSS-induced colitis. For the first time, we identified four therapeutic mechanisms of ZKC, including effective inhibition of the inflammatory responses, significant alleviation of intestinal epithelium apoptosis, considerable prevention of oxidative stress, and selective down-regulation of the MyD88-dependent TLR4 signaling pathway. With high therapeutic effects and low toxic effects, ZKC exhibits great superiority over western medicines in IBD treatment.

Abstract
Dyslipidemia and hyperglycemia are associated with an increased risk of ischemic cardiovascular disease. Positive effects of a nutraceutical combination comprising red yeast rice, berberine, policosanol, astaxanthin, coenzyme Q10 and folic acid (NComb) on plasma lipid and glucose levels have been reported in some but not all clinical trials. To address this inconsistency, we tried to estimate the size of lipid- and glucose-lowering effects of NComb through a systematic review and meta-analysis of randomized controlled trials. A systematic literature search in PubMed-Medline, SCOPUS and Google Scholar databases was conducted to identify randomized controlled trials investigating the effects of NComb on plasma lipids and glucose levels. Inverse variance-weighted mean differences (WMDs) and 95% confidence intervals (CIs) were calculated for net changes in lipid and glucose levels using a random-effects model. Random-effects meta-regression was performed to assess the effect of putative confounders on plasma lipid and glucose levels. Fourteen trials (1670 subjects in the NComb arm and 1489 subjects in the control arm) met the eligibility criteria for lipid analysis and 10 trials (1014 subjects in the NComb arm and 962 subjects in the control arm) for glucose analysis. Overall, WMDs were significant for the impact of NComb supplementation on plasma levels of total cholesterol (-26.15mg/dL, p<0.001), LDL-cholesterol (-23.85mg/dL, p<0.001), HDL-cholesterol (2.53mg/dL, p<0.001), triglycerides (-13.83mg/dL, p<0.001) and glucose (-2.59mg/dL, p=0.010). NComb-induced amelioration of lipid profile was not affected by duration of supplementation nor by baseline lipid levels; conversely, a greater glucose-lowering effect of NComb was found with higher baseline glucose levels and longer durations of supplementation. In conclusion, the present results suggest that NComb supplementation is associated with improvement of lipid and glucose profile. Short-term beneficial effects of NComb supplementation appear to be maintained in the long term.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE A wealth of information is emerging about the impact of gut microbiota on human health and diseases such as cardiovascular diseases, obesity and diabetes. As we learn more, we find out the gut microbiota has the potential as new territory for drug targeting. Some novel therapeutic approaches could be developed through reshaping the commensal microbial structure using combinations of different agents. The gut microbiota also affects drug metabolism, directly and indirectly, particularly towards the orally administered drugs. Herbal products have become the basis of traditional medicines such as traditional Chinese medicine and also been being considered valuable materials in modern drug discovery. Of note, low oral bioavailability but high bioactivity is a conundrum not yet solved for some herbs. Since most of herbal products are orally administered, the herbs' constituents are inevitably exposed to the intestinal microbiota and the interplays between herbal constituents and gut microbiota are expected. Emerging explorations of herb-microbiota interactions have an opportunity to revolutionize the way we view herbal therapeutics. The present review aims to provide information regarding the health promotion and/or disease prevention by the interplay between traditional herbs with low bioavailability and gut microbiota through gut microbiota via two different types of mechanisms: (1) influencing the composition of gut microbiota by herbs and (2) metabolic reactions of herbal constituents by gut microbiota. MATERIALS AND METHODS The major data bases (PubMed and Web of Science) were searched using "gut microbiota", "intestinal microbiota", "gut flora", "intestinal flora", "gut microflora", "intestinal microflora", "herb", "Chinese medicine", "traditional medicine", or "herbal medicine" as keywords to find out studies regarding herb-microbiota interactions. The Chinese Pharmacopoeia (2010 edition, Volume I) was also used to collect the data of commonly used medicinal herbs and their quality control approaches. RESULTS Among the 474 monographs of herbs usually used in the Chinese Pharmacopoeia, the quality control approach of 284 monographs is recommended to use high-performance liquid chromatography approach. Notably, the major marker compounds (>60%) for quality control are polyphenols, polysaccharides and saponins, with significant oral bioavailability conundrum. Results from preclinical and clinical studies on herb-microbiota interactions showed that traditional herbs could exert heath promotion and disease prevention roles via influencing the gut microbiota structure. On the other hand, herb constituents such as ginsenoside C-K, hesperidin, baicalin, daidzin and glycyrrhizin could exert their therapeutic effects through gut microbiota-mediated bioconversion. CONCLUSIONS Herb-microbiota interaction studies provide novel mechanistic understanding of the traditional herbs that exhibit poor oral bioavailability. "Microbiota availability" could be taken consideration into describing biological measurements in the therapeutic assessment of herbal medicine. Our review should be of value in stimulating discussions among the scientific community on this relevant theme and prompting more efforts to complement herb-microbiota interactions studies.

Abstract
The development of a fast hCCC method tailored to recover phenolics of Siberian barberry (Berberis sibirica, Berberidaceae) responsible for the observed strong antioxidant activity was performed. Initially, the optimization of extraction procedure was evaluated based on the antiradical potential assessment (DPPH and Folin-Ciocalteu assays). 100 °C methanol ASE extract exhibited the highest antiradical activity (IC50=60 ± 4 μg/mL), and a significant TPC (159 ± 2 mgGAE/g). Thorough determination of phenolic content by UHPLC-DAD-ESI(-)HRMS revealed the presence of 10 phenolics as major constituents, and several groups of alkaloids. pH-zone refining hCCC was chosen as the most promising method for the extract's fractionation due to the ionizable character of its constituents. For this purpose a MtBE-H2O (1:1) system with 10mM TEA and HCl was applied leading to a phenolic fraction, free of alkaloids, with higher antioxidant capacity (IC50=25 μg/mL, TPC=178 mg GAE/g). Additionally, fractionation of alkaloids was achieved resulting isolation of pharmacologically important alkaloids: magnoflorine and berberine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Huang-Lian-Jie-Du-Decoction (HLJDD) is a Traditional Chinese Medicine (TCM) clinical prescription noted for its neuroprotective effects. The total alkaloids, flavonoids, and iridoids are the main active components of HLJDD. In the present study we explored the possible effects of the total alkaloids, flavonoids, and iridoids from HLJDD on behavioral recovery and cortical neurogenesis after stroke. METHODS The stroke model was induced by permanent middle cerebral artery occlusion (pMACO). The total alkaloids (44 mg/kg), flavonoids (50 mg/kg), and iridoids (80 mg/kg) from HLJDD were orally administered for 2h after stroke and daily thereafter. Neurological function was assessed and then rats were sacrificed 7 days after pMACO. Following repeated intraperitoneal injections of the cell proliferation - specific marker 5-bromodeoxyuridine (BrdU) after stroke induction, precursor cell proliferation and differentiation was monitored by immunofluorescent staining. The levels of relevant proteins were determined by western blotting and the mRNA expressions were assessed by quantitative real time-polymerase chain reaction (qRT-PCR). RESULTS Total alkaloids, flavonoids and iridoids from HLJDD showed improved functional outcome after brain ischemia. The total alkaloids and iridoids increased number of BrdU-positive cells and enhanced neuronal differentiation in the cortex. Alkaloids-enhanced neurogenesis might be associated with increased VEGF, Ang-1, and Ang-2 protein expression. And the neuroproliferative effect of alkaloids was partially correlated with increased phosphorylation of AKT, and GSK-3β. Flavonoids treatment was found to promote differentiation of cortical precursor cells into neuronal but not glial cells, which may be at least attributable to the regulation of AKT, GSK-3β mRNA and Ang-1 protein levels. CONCLUSIONS Total alkaloids, iridoids and flavonoids from HLJDD promoted functional recovery likely via enhancing cortical neurogenesis and thus have potential as a treatment for ischemic brain injury.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional and local medicinal knowledge would be useful for finding pharmaceutical resources. Ethnopharmacological methods, especially quantitative analysis could help us to pre-screen herbs in field studies. "Using different plants as the same herb" is common in both traditional and local medicinal systems in China. In terms of medicine safety, it is not best choice, for it would lead to difficulty in controlling the quality, safety and efficacy of herbs. However, from the perspective of finding new resources for pharmaceutical industry, it would be beneficial. The usage of Huang-lian is one of the typical examples of "using different plants as the same herb". According to the previous Phytochemical and Pharmacological studies, berberine is the common effective compound of most of the species used as Huang-lian. Recently, berberine and other effective compounds of Huang-lian have gained much more attention and will become more popular in both medicinal researches and pharmaceutical industry. In our preliminary field work, we found that dozens of plant species might be used as Huang-lian by local people in Northwest Yunnan, an area well known by its rich biodiversity and culture diversity. These herbs might have potential value for pharmaceutical industry, for example, it could be used as the new resources to extract berberine and other effective compounds. Due to this, it is very necessary to collect, identify, document, and analyze the herbs used as Huang-lian in NW Yunnan. In the present study, we focused on that how to use traditional and local medicinal knowledge to find resources for pharmaceutical industry. MATERIAL AND METHODS In the field work, interviews and participative observation were used. In the quantitative analysis of the local knowledge, Informant consensus factor (Fic), Use value (UV) and Relative frequency of citation (RFC) were used. RESULTS AND DISCUSSION A total of 230 key informants were interviewed and 29 plant species belonging to 8 families and 11 genera used as Huang-lian were collected in the study area. Diarrhoea had the highest value of Fic.xiana had the highest value of UV and RFC. The main effective compounds of most of these species were related to the protoberberine group of isoquinoline alkaloids, e.g. berberine, jatrorrhizin and palmatine, according to the previous phytochemical studies. CONCLUSION The range of sources of Huang-lian were very wide in NW Yunnan. Treating diarrhoea was the most common use of these species, most of which contained berberine. Based on the results of quantitative analysis, M. duclouxiana may had the greatest potential to future uses, e.g. as a resource for pharmaceutical industry. In the present study, we did not discuss whether the herbs used as Huang-lian could replace the standard Huang-lian in traditional or local medicine or not, and we just wanted to explore how this phenomenon could be used to find new resources for pharmaceutical industry.

Abstract
Berberine, a benzylisoquinoline alkaloid, occurs as an active constituent in numerous medicinal plants and has an array of pharmacological properties. It has been used in Ayurvedic and Chinese medicine for its antimicrobial, antiprotozoal, antidiarrheal and antitrachoma activity. Moreover, several clinical and preclinical studies demonstrate ameliorative effect of berberine against several disorders including metabolic, neurological and cardiological problems. This review provides a summary regarding the pharmacokinetic and pharmacodynamic features of berberine, with a focus on the different mechanisms underlying its multispectrum activity. Studies regarding the safety profile, drug interactions and important clinical trials of berberine have also been included. Clinical trials with respect to neurological disorders need to be undertaken to exploit the beneficiary effects of berberine against serious disorders such as Alzheimer's and Parkinson's disease. Also, clinical studies to detect rare adverse effects of berberine need to be initiated to draw a complete safety profile of berberine and strengthen its applicability.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Banxia Xiexin decoction (BXD), one of a traditional Chinese medicine chronicled in Shang Han Lun, is commonly used to treat gastroenteritis, ulcerative colitis and diarrhea. In our study, we used current biomedical approaches to investigate the therapeutic efficacy of BXD and possible protective mechanism involved in inhibiting dextran sulfate sodium (DSS)-induced chronic ulcerative colitis model. MATERIALS AND METHODS Chronic DSS colitis was induced in C57BL/6 male mice by three cycles of 5 days of 2% DSS in drinking water, alternating with 5 days of normal water, totaling 30 days. In BXD group, the mice were administered at a dose of 8.7g/kg BXD for 5 days before and during DSS treatment via oral gavage per day. Mice in vehicle group and DSS group were given orally the same volume of drinking water, instead. Body weight, stool characters and hematochezia were observed everyday. The colorectal tissues were used to detect levels of TNF-α, IL-4, IL-10, IL-1β, IL-17, IL-23 and MPO by ELISA or qRT-PCR. The expression of COX-2, 8-Oxoguanine and Nrf2 were examined by IHC, and p-p65 was examined by western blotting. ThOD and the content of MDA were measured according to kits respectively. RESULTS BXD significantly protected against DSS-induced chronic ulcerative colitis by amelioration of body weight loss, DAI and histology score. The level of TNF-α, IL-1β, IL-17, IL-23, COX-2 and p-p65 were decreased significantly, while the level of IL-10 improved with the treatment of BXD. MDA, MPO and 8-Oxoguanine were decreased, meanwhile SOD activity and Nrf2 expression were elevated significantly by BXD. CONCLUSIONS BXD possesses the potential of anti-inflammation and anti-oxidation to treat colitis. The protective mechanism of BXD may involve in inhibition of NF-κBp65 activation and increasement of Nrf2 expression in colorectums of mice.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE With this study, we aimed to document traditional uses of medicinal plants in the western part of Aladaglar/Nigde. MATERIALS AND METHODS This study was conducted between 2003 and 2005. The research area was in the western part of the Aladaglar mountains. The settlements in Aladaglar (5 towns and 10 villages) were visited during the field work. The plants collected by the help of medicinal plant users. The plants were identified and voucher specimens prepared. These voucher specimens were kept at the Herbarium of Istanbul University Faculty of Pharmacy (ISTE). We collected the information by means of semi-structured interviews with 170 informants (90 men and 80 women). In addition, the relative importance value of the species was determined and the informant consensus factor (FIC) was calculated for the medicinal plants researched in the study. RESULTS According to the results of the identification, among 126 plants were used by the inhabitants and 110 species belonging to 40 families were used for medicinal purposes. Most of the medicinal plants used in Aladaglar/Nigde belong to the families Lamiaceae (25 species), Asteraceae (16 species), Apiaceae (7 species), Fabaceae (6 species) and Brassicaceae (5 species). The most commonly used plant species were Hypericum perforatumThymus sipyleus var. sipyleus, Rosa canina, Urtica dioica, Malva neglecta, Thymus leucotrichus, Salix alba, Mentha longifolia, Berberis crataegina, Juniperus oxycedrus, Viscum album subsp. abietis, Allium rotundum and Taraxacum stevenii. The most common preparations were infusion and decoction. The traditional medicinal plants have been mostly used for the treatment of cardiovascular diseases (86%), hemorrhoids (79%), urinary diseases (69%), diabetes (68%) and respiratory diseases (61%). CONCLUSION The use of traditional medicine was still widespread among the inhabitants of Aladaglar mountains/Nigde region. Due to the lack of medical facilities in the villages of Aladaglar mountains, local people prefer herbal treatment rather than medical treatment. This study identified not only the wild plants collected for medical purposes by local people of Aladaglar/Nigde, but also the uses and local names of these plants. This paper helps to preserve valuable information that may otherwise be lost to future generations.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Jinqi Jiangtang Tablet is a traditional Chinese anti-diabetic formula containing three ingredients: Coptis chinensis Franch. (dried rhizome of C. chinensis Franch., Coptis deltoidea C. Y. Cheng et Hsiao and Coptis teeta Wall.), Astragalus membranaceus (Fisch.) Bunge. (dried root of A. membranaceus (Fisch.) Bge. var. mongholicus (Bge. ) Hsiao and A. membranaceus (Fisch.) Bge. ) and Lonicera japonica Thunb. (dried alabastrum or with nascent flowers of L. japonica Thunb. ). Free radicals, α-glucosidase, α-amylase, aldose reductase and lipase are different targets related with diabetes. However, there are no chromatographic methods employed in screening the anti-diabetic compounds from natural products basing on these targets simultaneously. The present study was aimed at the establishment of a multi-targets integrated fingerprinting to clarify the possible mechanism of the action of Traditional Chinese Medicines which simultaneously contained multiple chemical characteristics and effects of constitutions. MATERIALS AND METHODS The multi-targets integrated fingerprinting was developed and validated to screen anti-diabetic compounds from natural products by using ultra-high-performance liquid chromatography/quadruple-time-of-flight mass spectrometry, fraction collector and microplate reader. Ultra performance liquid chromatography was employed to separate the components in Jinqi Jiangtang Tablet, which were identified by quadruple-time-of-flight mass spectrometry to acquire their structural information and collected by the fraction collector. Finally the active fractions were tested for scavenging 1, 1-diphenyl-2-picrylhydrazyl radical and inhibition of α-glucosidase, α-amylase, aldose reductase, and lipase activities in vitro by microplate reader. RESULTS Our tests revealed that the Jinqi Jiangtang Tablet showed inhibitory activity against α-glucosidase, α-amylase, aldose reductase and lipase with IC50 values of 0.80 ± 0.02 mg/mL, 1.28 ± 0.13 mg/mL, 0.80 ± 0.02 mg/mL, 1.90 ± 0.18 mg/mL respectively and the scavenging activity with IC50 value of 1.71 ± 0.178 mg/mL. The bioactive fractions were identified to be alkaloids, flavonoids and phenolic acids. The phenolic acids possessed antioxidant activities, namely the scavenging effect on 1, 1-diphenyl-2-picrylhydrazyl rull;). The alkaloids exhibited inhibitory activity against α-glucosidase, aldose reductase, α-amylase, and lipase. The flavonoids also showed mild inhibition on α-glucosidase, aldose reductase, α-amylase and lipase. CONCLUSIONS The results demonstrate that Jinqi Jiangtang Tablet can scavenge free radicals and inhibit α-glucosidase, aldose reductase, α-amylase and lipase, which may be the possible mechanism of action of Jinqi Jiangtang Tablet for the treatment of diabetes and associated complications. Compared with conventional chromatographic separation and activity assays, the multi-targets integrated fingerprinting, which simultaneously contains the chemical characteristics and multiple effects of constitutions could comprehensively and properly reveal the activity of Jinqi Jiangtang Tablet. The results also show that the multi-targets integrated fingerprinting is a novel and powerful tool for screening and identifying active ingredients from Traditional Chinese Medicines.

Abstract
Berberine is an isoquinoline with anti-inflammatory activity. We previously demonstrated that there was a loop of signal amplification between nuclear factor kappa B and Src for macrophage mobility triggered by the engagement of Toll-like receptors (TLRs). The simultaneous suppression of lipopolysaccharide (LPS)-mediated upregulation of inducible nitric oxide synthase, cyclooxygenase 2, and cell mobility in berberine-treated macrophages suggested Src might be a target of berberine. Indeed, th reduced migration, greatly suppressed Src induction in both protein and RNA transcript by berberine were observed in macrophages exposed to LPS, peptidoglycan, polyinosinic-polycytidylic acid, and CpG-oligodeoxynucleotides. In addition to Src induction, berberine also inhibited LPS-mediated Src activation in Src overexpressing macrophages and S-nitroso-N-acetylpenicillamine (a nitric oxide donor) could partly restore it. Moreover, berberine suppressed Src activity in fibronectin-stimulated macrophages and in v-Src transformed cells. These results implied that by effectively reducing Src expression and activity, berberine inhibited TLR-mediated cell motility in macrophages.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Xiexin decoction (XXD) has been used as a treatment for diabetes mellitus for more than 1300 years. XXD constituents with protective effects against diabetic nephropathy (DN) include Rhizoma Coptidis alkaloids (RA), Radix et Rhizoma Rhei polysaccharides (RP), and Radix Scutellaria flavones (RF). The aim of the study is to investigate the effects of combinations of RA, RP, and RF on DN and their mechanisms of action. MATERIALS AND METHODS In vitro, high glucose-induced rat mesangial cells were treated with RA, RP, RF, and combinations thereof. Cell proliferation and levels of inflammatory factors were measured. In vivo, high-fat diet and streptozotocin-induced diabetic rats were treated with different combinations of RA, RP, and RF once per day for 12 weeks. Blood and urine biochemical parameters, renal tissue morphology, and inflammation were investigated. RESULTS In vitro, the combination of the three groups of components inhibited mesangial cell proliferation and reduced the levels of monocyte chemotactic protein-1 (MCP-1) and collagen IV. The effects of the three constituent groups in combination were stronger than those of each group alone or combinations of two groups. In diabetic rats, combinations of the three groups of herb components ameliorated blood glucose, urinary albumin excretion and decreased renal mesangial matrix expansion and basement membrane thickening. In addition, the combinations reduced renal tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6) protein levels, down-regulated the expression of nuclear factor κB (NF-κB) and transforming growth factor beta 1 (TGF-β1), and up-regulated the expression of inhibitor of nuclear factor κB (IκB) protein. Among the three groups of herb components, RA produced the strongest effects, followed by RP, and then by RF. CONCLUSIONS The combination of the three groups of herb components produced anti-DN effects through inhibition of inflammation mediated by NF-κB. Among the three groups of herb components, RA produced the strongest effect while RP and RF produced weaker effects.
