Abstract
Actinobacteria, the bacterial phylum most renowned for natural product discovery, has been established as a valuable source for drug discovery and biotechnology but is underrepresented within accessible genome and strain collections. Herein, we introduce the Natural Products Discovery Center (NPDC), featuring 122,449 strains assembled over eight decades, the genomes of the first 8490 NPDC strains (7142 Actinobacteria), and the online NPDC Portal making both strains and genomes publicly available. A comparative survey of RefSeq and NPDC Actinobacteria highlights the taxonomic and biosynthetic diversity within the NPDC collection, including three new genera, hundreds of new species, and ~7000 new gene cluster families. Selected examples demonstrate how the NPDC Portal's strain metadata, genomes, and biosynthetic gene clusters can be leveraged using genome mining approaches. Our findings underscore the ongoing significance of Actinobacteria in natural product discovery, and the NPDC serves as an unparalleled resource for both Actinobacteria strains and genomes.

Abstract
A new species of Anoectochilus (Orchidaceae) from Guangxi, China, A.zhongshanensis, is described here, which was identified based on phylogenetic studies adopting combined plastid markers (rbcL-matK-trnL-F), morphological observation and chemical analysis. Molecular phylogenetic results support the systematic status of A.zhongshanensis as a new species in Anoectochilus genus. Morphologically, this new species is similar to A.zhejiangensis and A.malipoensis, but differs by its characteristic labellum and column, including the hastate or scalpel-shaped lobes of epichile, forward curved and pinnately divided cristate lobes at both sides of the mesochile and inverted triangle column wings. Furthermore, HPLC-ELSD analysis of these three species revealed the interesting chemotaxonomic difference that the principle and characteristic lactone glycoside in this new species was kinsenoside, rather than its diastereoisomer, goodyeroside A, a major glycoside in A.zhejiangensis and A.malipoensis.

Abstract
Endophytic fungi play important roles in regulating plant growth and development and usually used as a promising strategy to enhance the biosynthesis of host valuable secondary metabolite, but the underlying growth-promoting mechanisms are only partly understood. In this study, the wild-type Arabidopsis thaliana seedlings co-cultured with fungal endophyte Epichloë bromicola showed auxin (IAA)-stimulated phenotypes, and the growth-promoting effects caused by E. bromicola were further verified by the experiments of spatially separated co-culture and fungal extract treatment. IAA was detected and identified in the extract of E. bromicola culture by LC-HRMS/MS, whereas 2,3-butanediol was confirmed to be the predominant volatile active compound in the diethyl ether and ethyl acetate extracts by GC-MS. Further study observed that IAA-related genes including synthesis key enzyme genes (CYP79B2, CYP79B3, NIT1, TAA1 and YUCCA1) and controlling polar transport genes (AUX1, BIG, EIR1, AXR3 and ARF1), were highly expressed at different periods after E. bromicola inoculation. More importantly, the introduction of fungal endophyte E. bromicola could effectively promote the growth and accumulation of coixol in Coix under soil conditions. Our study showed that endophytic fungus E. bromicola might be considered as a potential inoculant for improving medicinal plant growth.

Abstract
Objective: To examine the efficacy and safety of laparoscopic surgery for gallbladder carcinoma. Methods: The data of 197 gallbladder carcinoma patients admitted at Peking Union Medical College Hospital between January 2012 and September 2022 were analyzed retrospectively. There were 86 males and 111 females,with age of (64.4±9.8)years(range:35 to 89 years). Patients were divided into laparoscopic group(n=53) and open group(n=144) according to different surgical methods. The general information of the two groups were matched by propensity score matching,and the clinical data and prognosis were compared between the two groups. Categorical variables were analyzed using χ2 test or Fisher's exact test,as appropriate. Continuous variables with and without normal distribution were analyzed using t-test and Mann-Whitney U test,respectively. Kaplan-Meier curves with Log-rank test were used to analyze the cumulative survival rates. Results: Forty-eight pairs of patients were matched successfully. There was no difference in general information,cholecystolithiasis,partial hepatectomy,and tumor stage between two groups(all P>0.05). The laparoscopic group had shorter operation time(t=-3.987,P<0.01),less bleeding(Z=-4.862,P<0.01),shorter total(Z=-5.009,P<0.01) and postoperative(Z=-5.412,P<0.01) hospital stay. Seventeen patients had postoperative complications. According to the Clavien-Dindo system,there were 4,11,1,and 1 patient with grade Ⅰ,Ⅱ,Ⅲa,and Ⅲb,respectively. All complications were improved after active treatment. After a median follow-up of 24(36) months(range:3 to 130 months),56 patients(58.3%) survived without tumor,7 patients(7.3%) survived with tumor,and 33 patients(34.4%) died. According to the Kaplan-Meier curves,there was no significant difference between laparoscopic and open groups in disease free(χ2=0.399,P=0.528) and overall(χ2=0.672,P=0.412) survival rates. Conclusions: The laparoscopic surgery is safe and effective in selected patients with gallbladder carcinoma. It can reduce surgical trauma and enhance patient recovery without increasing complication. Its prognosis is similar to that of open surgery.

Abstract
Objective: To investigate the efficacy and safety of enhanced recovery after surgery (ERAS) in perioperative management of patients with gallbladder carcinoma. Methods: The data of the patients with gallbladder carcinoma admitted at Peking Union Medical College Hospital between January 2017 and December 2021 were analyzed retrospectively. There were 69 males(42.1%) and 95 females(57.9%),with age of (64.0±10.3) years(range:37 to 89 years). Patients were divided into ERAS group(n=53) and normal group(n=111) according to whether they were treated with ERAS measures during the perioperative period.The basic characteristics of the two groups were matched by propensity score matching,and then the perioperative information was compared between the two groups. Categorical variables were presented as absolute numbers or frequencies. Differences between study groups were analyzed using χ2 test, Fisher's exact test, t-test, or Mann-Whitney U test, as appropriate. Results: Each group had 45 patients after propensity score matching with well-balanced basic characteristics. There was no difference in basic characteristics, operation time,bleeding,complication,and hospitalization expenses between two groups(all P>0.05). Compared with the normal group,time of ambulation (M(IQR)) (1(1) day vs. 2(2) days;Z=-3.839,P<0.01),postoperative anal exhaust time (2(1) days vs. 3(1) days;Z=-3.013,P=0.003),feeding time(2(1) days vs. 2(1) days;Z=-3.647,P<0.01),postoperative (5(2) days vs. 7(4) days;Z=-3.984,P<0.01) and total(8(4) days vs. 13(6) days;Z=-3.605,P<0.01) hospitalization time were shorter in ERAS group. Postoperative complications occurred in 12 patients. According to the Clavien-Dindo classification,6,4,and 2 patients were classified as grade Ⅰ,Ⅱ,and Ⅲa,respectively. Conclusion: The ERAS measures is safe and effective for perioperative management of patients with gallbladder carcinoma, enhancing patient recovery and shortening hospitalization time without increasing complication or hospitalization cost.

Abstract
The members of the arylamine N-acetyltransferase (NAT) family of enzymes are important for their many roles in xenobiotic detoxification in bacteria and humans. However, very little is known about their roles outside of detoxification or their specificities for acyl donors larger than acetyl-CoA. Herein, we report the detailed study of PtmC, an unusual NAT homologue encoded in the biosynthetic gene cluster for thioplatensimycin, thioplatencin, and a newly reported scaffold, thioplatensilin, thioacid-containing diterpenoids and highly potent inhibitors of bacterial and mammalian fatty acid synthases. As the final enzyme of the pathway, PtmC is responsible for the selection of a thioacid arylamine over its cognate carboxylic acid and coupling to at least three large, 17-carbon ketolide-CoA substrates. Therefore, this study uses a combined approach of enzymology and molecular modeling to reveal how PtmC has evolved from the canonical NAT scaffold into a key part of a natural combinatorial biosynthetic pathway. Additionally, genome mining has revealed the presence of other related NATs located within natural product biosynthetic gene clusters. Thus, findings from this study are expected to expand our knowledge of how enzymes evolve for expanded substrate diversity and enable additional predictions about the activities of NATs involved in natural product biosynthesis and xenobiotic detoxification.

Abstract
Objective: To understand the characteristics and changes of the incidence of amoebic dysentery in China during 2015-2018, explore the causes of high incidence in some areas and provide a data base for the development of national prevention and control strategies and measures. Methods: Data were collected from the infectious disease reporting management information system from Chinese Disease Control and Prevention. To understand the seasonal, population and area distributions of amoebic dysentery, descriptive epidemiological method and software SPSS 16.0 were used to analyze the amoebic dysentery data. Results: A total of 4 366 amoebic dysentery cases were reported without death in China during 2015-2018. The reported average annual incidence was 0.08/100 000, and the overall proportion of laboratory confirmed cases was 68.23%(2 979/4 366). Amoeba dysentery mainly occurred during May to October. One seasonal peak was observed in 2015 and 2017 (July and June, respectively), and two seasonal peaks were observed in 2016 and 2018 (June and October). The patients were mainly children aged under 5 years (42.28%, 1 846/4 366), and the incidence rate decreased with age in children aged under 10 years. Of these, children under 1 years of age had the highest incidence rate (1.28/100 000). The number of cumulative reported cases in Guangxi, Henan, Guangdong, Heilongjiang and Jiangxi provinces ranked top five from 2015-2018, accounting for 64.50% (2 816/4 366) of the total. The cumulative cases in Dongxing county, Guangxi, in Suixian county, Henan and in Ranghulu district, Heilongjiang, respectively accounted for more than 50.00% of the total number of cases in their provinces. Conclusions: The incidence rate of amoebic dysentery reported in China during 2015-2018 showed a decreasing trend, with a higher incidence in children under 5 years old and a higher number of cases in some areas. It is suggested to further investigate and analyze the diagnosis and reporting of amoeba dysentery in key areas and promote the update of the diagnostic standards for amoeba dysentery.

Abstract
Objective: To explore the epidemiological characteristics of Kala-azar disease in China from 2005 to 2015, to provide evidence for the development of related control and measurement strategies. Methods: Data was obtained from Disease Reporting Information System of China CDC, to compare factors on type, distribution, peak season and the age of onset of the cases. Results: Epidemic of Kala-azar had been persistent in China. Number of the reported cases declined in Sichuan and Gansu provinces but two outbreaks had occurred in Xinjiang Uygur autonomous region. The epidemic was confined in few areas. The reported cases were mainly from Xinjiang, Gansu and Sichuan, with the total cases in these three provinces accounted for 95.29% of all the cases seen in the country. The main peak season was from October to November, followed by April. There were significant differences seen in the age distributions of canine Kala-azar, anthroponotic Kala-azar and wildlife-oriented Kala-azar (P<0.05) cases. Majority of the cases involved under 3-year-olds, with peak age in under 1-year-olds for wildlife-oriented Kala-azar. For anthroponotic and canine Kala-azar cases, most of them were seen among the under 10 years old, with the peak among the 5-year-olds. Conclusions: In recent years,Kala-azar had been seen endemic and persistent, in the mid-west regions of China, but with different epidemiological characteristics. Further study on Kala-azar should be carried on to include appropriate measurements and strategies, according to the features of the disease, in the mid-western areas of China.

Abstract
A wide range of external stress stimuli trigger plant cells to undergo complex network of reactions that ultimately lead to the synthesis and accumulation of secondary metabolites. Accumulation of such metabolites often occurs in plants subjected to stresses including various elicitors or signal molecules. Throughout evolution, endophytic fungi, an important constituent in the environment of medicinal plants, have known to form long-term stable and mutually beneficial symbiosis with medicinal plants. The endophytic fungal elicitor can rapidly and specifically induce the expression of specific genes in medicinal plants which can result in the activation of a series of specific secondary metabolic pathways resulting in the significant accumulation of active ingredients. Here we summarize the progress made on the mechanisms of fungal elicitor including elicitor signal recognition, signal transduction, gene expression and activation of the key enzymes and its application. This review provides guidance on studies which may be conducted to promote the efficient synthesis and accumulation of active ingredients by the endogenous fungal elicitor in medicinal plant cells, and provides new ideas and methods of studying the regulation of secondary metabolism in medicinal plants.

Abstract
Brucellosis is an occupational disease affecting workers in butcher shops, the milking and dairy product industry, causing more than 500 000 new cases around the world. As a national statutory B infectious disease in China, morbidity of brucellosis is rapidly increasing in recent years. We report an occupational outbreak of brucellosis infection in a pharmaceutical factory. Exposure was a result of manual operation in the process line, close contact with sheep placentas, insufficient disinfection and repeated using of protective suits and infected by aerosol dissemination. Improved preventive methods, appropriate public health measures and spread of health education would be helpful to prevent the occupational outbreak of brucellosis in future.

Abstract
Endophytic fungi or endophytes exist widely inside the healthy tissues of living plants, and are important components of plant micro-ecosystems. Over the long period of evolution, some co-existing endophytes and their host plants have established a special relationship with one and another, which can significantly influence the formation of metabolic products in plants, then affect quality and quantity of crude drugs derived from medicinal plants. This paper will focus on the increasing knowledge of relationships between endophytic fungi and medicinal plants through reviewing of published research data obtained from the last 30 years. The analytical results indicate that the distribution and population structure of endophytes can be considerably affected by factors, such as the genetic background, age, and environmental conditions of their hosts. On the other hand, the endophytic fungi can also confer profound impacts on their host plants by enhancing their growth, increasing their fitness, strengthening their tolerances to abiotic and biotic stresses, and promoting their accumulation of secondary metabolites. All the changes are very important for the production of bioactive components in their hosts. Hence, it is essential to understand such relationships between endophytic fungi and their host medicinal plants. Such knowledge can be well exploited and applied for the production of better and more drugs from medicinal plants.

Abstract
The genus Fagopyrum (Polygonaceae), currently comprising 15 species of plants, includes three important buckwheat species: Fagopyrum esculentum (F. esculentum) Moench. (common buckwheat), Fagopyrum tataricum (F. tataricum) (L.) Gaertn. (tartary buckwheat) and Fagopyrum dibotrys (F. dibotrys) (D. Don) Hara. (perennial buckwheat), which have been well explored due to their long tradition of both edible and medicinal use. This review aimed to present an up-to-date and comprehensive analysis of the phytochemistry and pharmacology of the three Fagopyrum buckwheats. In addition, the scope for future research was also discussed. All available references included in this paper were compiled from major databases, such as MEDLINE, Pubmed, Scholar, Elsevier, Springer, Wiley and CNKI. A total of 106 compounds isolated from three Fagopyrum buckwheats can be mainly divided into six classes: flavonoids, phenolics, fagopyritols, triterpenoids, steroids and fatty acids. Flavonoids and phenolic compounds were considered to be the major active components. Considerable pharmacological experiments both in vitro and in vivo have validated that Fagopyrum buckwheats possess antitumor, anti-oxidant, anti-inflammatory, hepatoprotective, anti-diabetic activities, etc. All reported data lead us to conclude that Fagopyrum buckwheats have convincing medicinal potential. However, further research is needed to explore its bioactive constituents, the relationship to their structural activities and the molecular mechanisms of action.

Abstract
BACKGROUND Podocarpium podocarpum (DC.), an edible and medicinal plant popularly used for the treatment of bruises and fracture in Chinese folk medicine, has been proved to possess significant antiosteoporotic effect in our latest research. PURPOSE Our study aimed to investigate the in vitro and in vivo antiosteoporotic effect of kaempfertrin (KN), a principal flavonoid in P. podocarpum obtained through bio-guided isolation. METHODS An ovariectomized (OVX) rat model of osteoporosis as well as in vitro osteoblast and osteoclast cell lines were employed to evaluate the antiosteoporotic potency of KN. RESULTS KN significantly improved the bone mass and microarchitecture in OVX rats, with little estrogen-like side effect compared with estradiol valerate. KN also exhibited stimulatory effect on osteoblastic cells and inhibitory action on osteoclastic cells, which down-regulated the phosphorylation level of I-κB. CONCLUSION KN possessed significant antiosteoporotic activity. Combined with its limited estrogen-like side effect, KN can be regarded as an idealistic antiosteoporotic candidate for human osteoporosis diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Currently, human liver is susceptible to injury caused by alcohol and virus infiltration, resulting in hepatitis, cirrhosis, and even hepatocellular carcinoma. Paederia scandens (Lour.) Merr. var. tomentosa (Rubiaceae) has been used as traditional medicine in Asian countries to treat jaundice, dysentery, and abdominal mass. Furthermore, the abundance of iridoid glycosides in Paederia species indicates their notable hepatoprotective potential. MATERIALS AND METHODS Total iridoid glycosides (TG) was prepared, and constituents of TG were analyzed by HPLC. TG and silymarin (positive) were orally administered for 15 days. Then, acute liver injury rats was induced by intraperitoneally injection (i.p.) of 10% CCl4 (0.12%, v/v, dissolved in olive oil, 10 mL/kg, body weight). Rats were sacrificed at 16 h after CCl4 injection. Liver tissues and blood were collected. Serum samples were prepared to determine the activities of alanine transaminase (ALT) and aspartate transaminase (AST), whereas liver tissue sections were prepared for the purpose of examining possible liver histopathological changes. In addition, antioxidant enzyme activities in liver tissues were also evaluated. RESULTS Our results demonstrated that TG significantly decreased the levels of AST and ALT, compared with those in control rats. In addition, pre-treatment of the rats with TG clearly alleviated their liver tissue injuries. What's more, the activities of GSH, GAT and SOD in the groups of TG-treated rats were significantly increased compared with those of rats in the control group, whereas the levels of MDA were decreased. CONCLUSIONS Our present research indicated that TG possessed notable hepatoprotective activity via decreasing oxidative stress level in liver tissues.

Abstract
Our study aimed to investigate the antiosteoporotic properties of the ethanol extract of Podocarpium podocarpum (DC.) Yang et Huang (PE) in ovariectomized (OVX) rats and to characterize the active constituents. As a result, PE significantly inhibited the increased urinary Ca excretion and activity of bone resorption markers including tartrate-resistant acid phosphatase (TRAP), deoxypyridinoline crosslinks and cathepsin K in OVX rats, whereas exhibited little effects on the body, uterus and vagina weight. Detailed micro-CT analysis showed that PE notably enhanced bone quality, with increased bone mineral content (BMC), bone volume fraction (BVF), connectivity density (CD), tissue mineral content (TMC), tissue mineral density (TMD) and trabecular number (Tb. N), and decreased trabecular separation (Tb. Sp), in OVX animal. Those findings implied that PE had notable antiosteoporotic effect, especially effective in preventing bone resorption, with little side-effects on reproductive tissue. Further chemical investigation led to the isolation of 17 flavonoids, most of which showed significantly stimulatory effect on osteoblastic proliferation, ALP activity and mineralized nodes formation as well as inhibitory effect on osteoclastic TRAP activity in osteoblastic and osteoclastic cells. Our results indicated that PE, with abundant flavonoids, had remarkable antiosteoporotic activity and therefore can be a promising candidate for the treatment of postmenopausal osteoporosis induced by estrogen deficiency through herbal remedy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Xanthium strumarium L. fruit (Xanthiu fruit) has been traditionally used as a medicinal herb in China for the treatment of many ailments including rheumatoid arthritis. However, the anti-arthritic activity of Xanthium strumarium fruit has still not been demonstrated. In the present study, we confirmed that the extract of Xanthium strumarium (EXS) prevents rheumatoid arthritis induced by Complete Freund׳s Adjuvant (CFA) in rats. MATERIALS AND METHODS Male Wistar rats (160±10 g) were immunized by intradermal injection of 0.1 mL of CFA into the left hind metatarsal footpad. EXS was administered orally at a dose of 300 and 75 mg/kg once a day after the induction of adjuvant arthritis. Methotrexate (3 mg/kg, twice a week) was used as a positive control. Paw swelling, arthritic score, body weight loss, spleen index, thymus index, serum cytokines, inflammatory mediators and histological change were measured. The chemical profile of EXS was analyzed by HPLC-DAD. RESULTS We found that the EXS significantly suppressed paw swelling and arthritic score, increased body weight loss and decreased the thymus index. The overproduction of TNF-α and IL-1β were remarkably suppressed in the serum of all EXS-treated rats, and in contrast IL-10 was markedly increased. The level of COX-2 and 5-LOX was also decreased with EXS treatment. Ten phenolic acid derivatives were identified from 14 detected peaks by HPLC-DAD with the reference substances and verified by LC-MS. CONCLUSIONS These results suggest the potential effect of EXS as an anti-arthritis agent towards CFA-induced arthritis in rats. Xanthium strumarium has the potential to be regarded as a candidate for use in general therapeutics and as an immune-modulatory medicine in rheumatoid arthritis.

Abstract
The development of plant tissue (including organ and cell) cultures for the production of secondary metabolites has been underway for more than three decades. Plant cell cultures with the production of high-value secondary metabolites are promising potential alternative sources for the production of pharmaceutical agents of industrial importance. Medicinal plant cell suspension cultures (MPCSC), which are characterized with the feature of fermentation with plant cell totipotency, could be a promising alternative "chemical factory". However, low productivity becomes an inevitable obstacle limiting further commercialization of MPCSC and the application to large-scale production is still limited to a few processes. This review generalizes and analyzes the recent progress of this bioproduction platform for the provision of medicinal chemicals and outlines a range of trials taken or underway to increase product yields from MPCSC. The scale-up of MPCSC, which could lead to an unlimited supply of pharmaceuticals, including strategies to overcome and solution of the associated challenges, is discussed.

Abstract
The fruits of Xanthium strumarium L. (Asteraceae) have been used extensively in China for treatment of various diseases such as allergic rhinitis (AR), tympanitis, urticaria and arthritis or ozena. This study was designed to systemically investigate the effects of the caffeoylxanthiazonoside (CXT) isolated from fruits of X. strumarium on AR in rodent animals. Animals were orally administered with CXT. Anti-allergic activity of CXT was evaluated by passive cutaneous anaphylaxis test (PCA); acetic acid-induced writhing tests were used to evaluate the analgesic effects of CXT; acetic acid-induced vascular permeability tests were performed to evaluate anti-inflammatory effect of CXT. Then, the model AR in rats was established to evaluate the effects of CXT on AR with the following tests: the sneezing and nasal scratching frequencies, IgE level in serum, and histopathological examinations. Our results demonstrated that CXT had favorable anti-allergic, anti-inflammatory and analgesic effects. Additionally, we found that CXT was helpful to ameliorate the nasal symptoms and to down-regulate IgE levels in AR rats. Thus, we suggested that CXT can be treated as a candidate for treating AR.

Abstract
The seeds of Vitex negundo L. (Verbenaceae) have been commonly used as a folk remedy for the treatment of rheumatism and joint inflammation in Traditional Chinese Medicine. This study aimed to evaluate the anti-arthritic activity of the extract of V. negundo seeds (EVNS) using Freund's complete adjuvant (CFA) induced arthritis (AA) in rat model. As a result, EVNS, with abundant phenylnaphthalene-type lignans, significantly inhibited the paw edema, decreased the arthritis score and spleen index, and reversed the weight loss of CFA-injected rats. Histopathological studies showed a marked decrease of synovial inflammatory infiltration and synovial lining hyperplasia in the joints of EVNS-treated animals. The remarkable decrement of serum inflammatory factors (TNF-α, IL-1β and IL-6) were observed in EVNS-treated rats, whereas, IL-10, an anti-inflammatory cytokine, was found to be significantly increased by EVNS. The expressions of COX-2 and 5-LOX in PBMC were also inhibited by administration of EVNS. Our results demonstrated that V. negundo seeds possessed potential therapeutic effect on adjuvant induced arthritis in rats by decreasing the levels of TNF-α, IL-1β and IL-6 and increasing that of IL-10 in serum as well as down-regulating the levels of COX-2 and 5-LOX, and therefore may be an effective cure for the treatment of human rheumatoid arthritis.

Abstract
INTRODUCTION Cervical cancer, the second most common gynecological malignant tumor seriously harmful to the health of women, remains a leading cause of cancer-related death for women in developing countries. Although a large amount of scientific research has been reported on plants as a natural source of treatment agents for cervical cancer, it is currently scattered across various publications. A systematic summary and knowledge of future prospects are necessary to facilitate further plant studies for anti-cervical cancer agents. AREAS COVERED This review generalizes and analyzes the current knowledge on the anti-cervical cancer properties and mechanisms involved for plants, and discusses the future prospects for the application of these plants. EXPERT OPINION This review mainly focuses on the plants which have been scientifically tested in vitro and/or in vivo and proved as potential agents for the treatment of cervical cancer. The failure of conventional chemotherapy to reduce mortality as well as serious side effects involved makes natural products ideal candidates for exerting synergism and attenuation effects on anticancer drugs. Although the chemical components and mechanisms of action of natural plants with anti-cervical cancer potential have been investigated, many others remain unknown. More investigations and clinical trials are necessary to make use of these medical plants reasonably.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The dried root of Litsea cubeba (Lour.) Pers. (Family Lauraceae) has long been used as a folk remedy in Traditional Chinese Medicine (TCM) and Dai Ethnopharmacy for the treatment of rheumatic diseases in southwestern China. AIM OF THE STUDY This study investigated the preventive efficacy of Litsea cubeba root in treating rheumatoid arthritis using Freund's complete adjuvant (CFA) induced arthritis (AA) in rat model. MATERIALS AND METHODS Arthritis was induced in male Wistar rats by immunization with CFA. Ethanol extract (EELC) and water extract (WELC) of Litsea cubeba root both at 50mg/kg and 200mg/kg were orally administered from a day after the induction of arthritis. Paw swelling, arthritic score, body weight growth rate, index of thymus and spleen were observed, and the production of TNF-α, IL-1β, IL-6 and IL-10 in serum were measured by enzyme-linked immunosorbent assay. The expression levels of inflammatory enzymes like cyclooxygenase and lipoxygenase were also measured by enzyme-linked immunosorbent assay. Moreover, histological changes in the ankle joint were analyzed in AA rats. RESULTS Both EELC and WELC significantly suppressed paw swelling and arthritic score, increased the loss in body weight and decreased the index of thymus. Histopathological improvement in joint architecture was also observed in EELC, WELC-treated AA rats. The expression levels of cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) were decreased on treatment with EELC and WELC. Furthermore, the overproduction of TNF-α, IL-1β and IL-6 were remarkably attenuated in serum of all Litsea cubeba-treated rats, however, IL-10 was markedly increased at doses of 50mg/kg of EELC and WELC. CONCLUSIONS These results indicate that extract of Litsea cubeba root significantly attenuates adjuvant arthritis in rats by decreasing the levels of TNF-α, IL-1β and IL-6 and increasing of IL-10 in serum as well as down-regulate the levels of inflammatory enzymes such as COX-2 and 5-LOX. This suggests that Litsea cubeba root might be used as a therapeutic agent for the treatment of human arthritis.

Abstract
Based on bioactivity-oriented isolation, the EtOAc extract of a culture broth of the endophytic fungus Perenniporia tephropora Z41 from Taxus chinensis var. mairei, with strong anti-Pyricularia oryzae activity, afforded a new sesquiterpenoid, perenniporin A (1), together with three known compounds, ergosterol (2), rel-(+)-(2aR,5R,5aR,8S,8aS,8bR)-decahydro-2,2,5,8-tetramethyl-2H-naphtho[1,8-bc]genfuran-5-ol (3), and albicanol (4). Their structures were elucidated by means of spectroscopic methods. All the isolated compounds and the EtOAc extract of P. tephropora Z41 (EPT) were evaluated for their cytotoxic activity against three human cancer cell lines (HeLa, SMMC-7721, and PANC-1). EPT demonstrated significant cytotoxicity with IC(50) values ranging from 2 to 15 μg/mL. Compound 2 was the most cytotoxic constituent against the tested cell lines with IC(50) values of 1.16, 11.63, and 11.80 μg/mL, respectively, while compounds 1, 3, and 4 exhibited moderate cytotoxicity with IC(50) values ranging from 6 to 58 μg/mL. We conclude that the endophytic fungus P. tephropora is a promising source of novel and cytotoxic metabolites.

Abstract
CONTEXT Vitex negundo Linn. (Verbenaceae) seeds are pepper substitute and occasionally used as a condiment for edible purposes. The seeds also find use for analgesia, sedation, rheumatism and joint inflammation in folk medicine. OBJECTIVE To isolate and characterize bioactive constituents from V. negundo seeds. MATERIALS AND METHODS The ethanol extract of V. negundo seeds was subjected to repeated column chromatography. Chemical structures were elucidated by detailed spectroscopic analyses on the basis of NMR, IR, and MS data. Several pathogenic fungi isolates were employed to evaluate the antifungal activity of the isolated compound. RESULTS Chemical investigations of the seed extract afforded a new labdane diterpenoid, named negundol (1a + 1b), as an inseparable mixture of two diastereoisomers in a 5:4 ratio. Their structures were identified as (rel 3S, 5S, 8R, 9R, 10S, 13S, 16S)-3-acetoxy-9, 13-epoxy-16-hydroxy-labda-15, 16-olide (1a), and (rel 3S, 5S, 8R, 9R, 10S, 13S, 16R)-3-acetoxy-9, 13-epoxy-16-hydroxy-labda-15, 16-olide (1b). Compound 1 was active as an antifungal agent with MIC₈₀ values in the range of 16-64 μg/mL. DISCUSSION AND CONCLUSION The presence of compound 1 in V. negundo is of chemotaxonomic significance, since plants under the genus Vitex are chemically characterized with labdane diterpenoids. Compound 1 exhibited potential antifungal activity and may be considered a lead compound for promising antifungal agent.

Abstract
CONTEXT Endophytic fungi are microorganisms living within the tissues of host plants, and have proven to be rich sources of biologically active secondary metabolites and therefore have attracted increasing attention in recent years. OBJECTIVE To isolate and characterize bioactive constituents from the endophytic fungus cultures of Crocus sativus Linn. (Iridaceae). MATERIALS AND METHODS Endophytes were isolated from the corm of C. sativus. Endophytic fungus cultures were subjected to repeated column chromatography. Chemical structure was elucidated based on extensive spectroscopic methods and X-ray diffraction analysis. Several pathogenic fungi isolates and tumor cell lines were employed to evaluate the antifungal and cytotoxic activities of the isolated compound. RESULTS An isolate of Penicillium vinaceum (strain no. X17) was obtained from the corm of C. sativus. Chemical investigations of the endophyte culture broth afforded an unique quinazoline alkaloid (1), identified as (-)-(1R,4R)-1,4-(2,3)-indolmethane-1-methyl-2,4-dihydro-1H-pyrazino-[2,1-b]-quinazoline-3,6-dione, which showed cytotoxic (IC(50) range 40.55-76.83 μg/mL) and antifungal (MIC(80) range 16-64 μg/mL) activities. DISCUSSION AND CONCLUSIONS Endophytes in C. sativus can be a rich source of novel bioactive compounds, which prompts us to expand the medicinal resource of this valuable plant in another way. Compound 1 exhibited potential cytotoxic and antifungal activities and may be considered a lead compound for promising antifungal and anticariogenic agent.

Abstract
CONTEXT Crocus sativus Linn. (Iridaceae), commonly known as saffron, becomes more and more popular due to its versatile biological and medicinal properties. At present, studies mainly focus on the traditional medicinal part, the saffron stigma, with less attention to the other parts of saffron, such as the perianth, the stamen, and the corm, which are high yield compared to the stigma and also possess various pharmacological effects. OBJECTIVE To determine the chemical compositions, antifungal, cytotoxic, and antioxidant activities of the ether fractions from the stamen, perianth, and stigma of saffron. MATERIALS AND METHODS The chemical constituents of the ether fractions from different parts of saffron were investigated by gas chromatography/mass spectrometry. Several pathogenic fungi isolates and tumor cell lines were employed to evaluate the antifungal and cytotoxic activities of these three ether fractions. 1,1-Diphenyl-2-picrylhydrazyl assay was used to determine the free radical-scavenging activity. RESULTS The ether fractions composition of the three C. sativus parts are different from each other, but lauric acid, hexadecanoic acid, 4-hydroxydihydro-2(3H)-furanone, and stigmasterol were the common constituents shared by all the three fractions. The stamen ether fraction displayed the strongest antifungal and cytotoxic activities, whereas both of the saffron stamen and perianth ether fractions exhibited significant antioxidant activities. DISCUSSION AND CONCLUSION These findings demonstrate that the saffron stamen and perianth possess significant antifungal, cytotoxic, and antioxidant activities as well as the stigma, though not to the same extent, prompting us to expand the medicinal resource and make best use of this valuable plant.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Desmodium podocarpum is a plant that has been used in the folk medicine to treat febrile diseases, cough and bleeding wounds. However, there is no scientific basis or reports in the modern literature regarding its effectiveness as an analgesic, anti-inflammatory and antipyretic agent. AIMS OF THE STUDY The objective of this study is to evaluate the analgesic, anti-inflammatory and antipyretic activities of the petroleum ether fraction (PEF) from the ethanol extract of Desmodium podocarpum. MATERIALS AND METHODS PEF (50, 100, 200 mg/kg) was estimated for its pharmacological properties by using the acetic acid-induced writhing test, the hot plate test, the Carrageenan-induced rat paw edema model, the dimethylbenzene-induced mouse inflammation model, and the lipopolysaccharide (LPS)-induced rat fever model. In addition, the acute toxicity of PEF was also studied. RESULTS PEF significantly and dose-dependently inhibited the writhing responses in mice, increased reaction time of mice in the hot plate test, reduced carrageenan-induced paw edema in rats and the dimethylbenzene-induced ear edema in mice, and attenuated LPS-induced fever in rats. No death of mice was observed when orally administered PEF up to 4.2 g/kg. CONCLUSIONS These findings suggest that PEF possesses evident analgesic, anti-inflammatory and antipyretic activities, and has a favorable safety, which supports the use of Desmodium podocarpum as an analgesic, anti-inflammatory and antipyretic drug in the folk medicine.

Abstract
The crude extract of Acanthopanax senticosus (AS) has been used extensively in Russia, China, Korea and Japan as an adaptogenic agent to fight against stress and fatigue. However, whether the liposoluble fraction possesses antifatigue activity or not is still unclear. A liposoluble fraction was administered orally to mice for 9 days. The swimming time to exhaustion was longer in the treatment groups (22.2 ± 3.3, 25.5 ± 4.8 min) than in the control group (13.7 ± 1.2 min, p < 0.05). The plasma TG (triglyceride) and BUN (blood urea nitrogen) levels in the high dose (500 mg/kg) groups were decreased significantly compared with the control group. Plasma lactate dehydrogenase (LDH) was lower in the treatment groups than in the control group. Chemical analysis from GC/MS revealed that the main components of the liposoluble fraction of AS were saturated fatty acid (12.98%), unsaturated fatty acid (33.13%), unsaturated alcohol (27.46%) and diolefine (15.76%). In conclusion, the liposoluble fraction enhanced the forced swimming capacity of mice by decreasing muscle damage, effectively preventing the increase in BUN concentration and increasing fat utilization. It is proposed that the antioxidant effect may be one of the antifatigue mechanisms of the liposoluble fraction of AS.

Abstract
The antinociceptive activities of the petroleum ether fraction (PEF) from the aqueous ethanol extract of Vitex negundo Linn. (Verbenaceae) seeds have been evaluated in several nociceptive mouse models. Given orally, the PEF (at doses of 12, 24, and 48 mg/kg body weight) produced significant dose-related inhibitions on chemical nociception induced by intraperitoneal acetic acid and sub-plantar formalin injections and on thermal nociception in the hot-plate test. Naloxone (1 mg/kg bw subcutaneously), a non-selected opioid receptor antagonist, notably reversed the analgesic effect caused by the PEF (48 mg/kg bw) when assessed against the first phase of the formalin test, but this effect was less significant for the PEF in the second phase. Our observations suggest that the PEF probably interacted with the opioid system and may be more effective on inflammatory pain. In addition, potent anti-inflammatory activity of the PEF was observed in the xylene-induced ear edema test, which further indicates that the analgesic effects of the PEF may be partially mediated by its anti-inflammatory activity. Further chemical analysis suggests that the analgesic activities of the PEF could be mostly due to the abundance of fatty acids with synergetic effects in the present work.

Abstract
A number of therapeutic targets have been explored for developing anticancer drugs. Continuous efforts have been directed at the discovery of new targets as well as the improvement of therapeutic efficacy of agents directed at explored targets. There are 84 and 488 targets of marketed and investigational drugs for the treatment of cancer or cancer related illness. Analysis of these targets, particularly those of drugs in clinical trials and US patents, provides useful information and perspectives about the trends, strategies and progresses in targeting key cancer-related processes and in overcoming the difficulties in developing efficacious drugs against these targets. The efficacy of anticancer drugs directed at these targets is frequently compromised by counteractive molecular interactions and network crosstalk, negative and adverse secondary effects of drugs, and undesired ADMET profiles. Multi-component therapies directed at multiple targets and improved drug targeting methods are being explored for alleviating these efficacy-reducing processes. Investigation of the modes of actions of these combinations and targeting methods offers clues to aid the development of more effective anticancer therapies.

Abstract
A new phenyldihydronaphthalene-type lignan, vitexdoin A (1), a new phenylnaphthalene-type lignan alkaloid, vitedoamine B (2), four new phenylnaphthalene-type lignans, vitexdoins B-E (3-6), and four known lignan derivatives (7-10) were isolated from Vitex negundo seeds. Their structures were elucidated by detailed analyses of NMR, IR, and MS data. The ability of the isolates to prevent nitric oxide (NO) production by LPS-stimulated RAW 264.7 macrophages in a concentration-dependent manner was also studied. Compounds 5, 6, and 9 were among the most potent NO production inhibitors, with IC(50) values of 0.13, 0.15, and 0.11 microM, respectively. The introduction of free hydroxy groups plays a vital role in the potency of these compounds.
