RESUMO
Strategies for treating osteoarthritis (OA) have become a research focus because an effective treatment for OA is unavailable. The objective of this study was to explore the effects and underlying mechanisms of glutamine (Gln) in OA. First, the chondrocytes were identified and a standard IL-1ß-induced OA model was established. After treatment with Gln or saline, the viability and apoptosis of chondrocytes were evaluated using a CCK-8 assay and flow cytometry analysis, which revealed that Gln can improve the IL-1ß-induced OA cells. Meanwhile, Gln can enhance the expression of aggrecan and collagen II, which are protective proteins for articular cartilage. Instead, Gln inhibited the expression of matrix metalloproteinase-1 (MMP-1) and matrix metalloproteinase-13 (MMP-13), which can degrade cartilage. To better understand the underlying mechanisms of Gln in IL-1ß-induced chondrocytes, the classical OA pathways of JNK and NF-κB were examined at the protein and mRNA levels using western blot and qRT-PCR analyses. We found that JNK and NF-κB were downregulated gradually depending on the Gln dose and protective and destructive factors changed based on changes of JNK and NF-κB. The effects of high-dose Gln were more effective than low-dose. Moreover, Gln was applied to the animal OA model to check the effects in vivo. The results showed that Gln attenuated cartilage degeneration and decreased OARSI scores, which demonstrated that Gln can improve OA. The experiments showed that Gln can benefit mice with OA by inhibiting the JNK and NF-κB signaling pathways.

Background: This study aimed to establish a novel quantification system of ferroptosis patterns and comprehensively analyze the relationship between ferroptosis score (FS) and the immune cell infiltration (ICI) characterization, tumor mutation burden (TMB), prognosis, and therapeutic sensitivity in left-sided and right-sided colon cancers (LCCs and RCCs, respectively). Methods: We comprehensively evaluated the ferroptosis patterns in 444 LCCs and RCCs based on 59 ferroptosis-related genes (FRGs). The FS was constructed to quantify ferroptosis patterns by using principal component analysis algorithms. Next, the prognostic value and therapeutic sensitivities were evaluated using multiple methods. Finally, we performed weighted gene co-expression network analysis (WGCNA) to identify the key FRGs. The IMvigor210 cohort, TCGA-COAD proteomics cohort, and Immunophenoscores were used to verify the predictive abilities of FS and the key FRGs. Results: Two ferroptosis clusters were determined. Ferroptosis cluster B demonstrated a high degree of congenital ICI and stromal-related signal enrichment with a poor prognosis. The prognosis, response of targeted inhibitors, and immunotherapy were significantly different between high and low FS groups (HSG and LSG, respectively). HSG was characterized by high TMB and microsatellite instability-high subtype with poor prognosis. Meanwhile, LSG was more likely to benefit from immunotherapy. ALOX5 was identified as a key FRG based on FS. Patients with high protein levels of ALOX5 had poorer prognoses. Conclusion: This work revealed that the evaluation of ferroptosis subtypes will contribute to gaining insight into the heterogeneity in LCCs and RCCs. The quantification for ferroptosis patterns played a non-negligible role in predicting ICI characterization, prognosis, and individualized immunotherapy strategies.

From the aerial extracts of Coptosapelta diffusa (Champ. ex Benth.) Steenis, twenty-one compounds were isolated and identified by means of column chromatography and NMR and MS techniques, respectively. Amongst, ten ones were determined to be undescribed compounds including six seco-iridoid glucosides (1-6), 2-(hydroxymethyl)-1,2,3,4-tetrahydroanthracene-9,10-dione (7) and three guaiane-type sesquiterpenes (15-17). Compounds 7, 8 and 9 exhibited inhibitory activities against Staphylococcus aureus ATCC25923 with MIC of 8, 4 and 8 µg/mL. The use of 1-6 (iridoids), 7-14 (anthraquinones) and 15-17 (sesquiterpenes) as chemotaxonomic markers for this species was evidenced. Structurally, 7-14 are similar to those anthraquinones isolated from other species of the family Rubiaceae, confirming their close phylogenetic relationship. Whereas, these iridoids and sesquiterpenes with unique structures provided chemotaxonomic evidence to support the genus Coptosapelta (the tribe Coptosapelteae) as a sister of the subfamily Rubioideae. These results contrast with the general producing tendency of indole alkaloids by the species of the subfamily Cinchonoideae, and merit chemotaxonomic significance for the delimitation of Coptosapelta.

BACKGROUND: Previous reports have suggested that the p38 mitogen-activated protein kinase signaling pathway is involved in the development of severe acute pancreatitis (SAP)-related acute lung injury (ALI). Inhibition of p38 by SB203580 blocked the inflammatory responses in SAP-ALI. However, the precise mechanism associated with p38 is unclear, particularly in pulmonary microvascular endothelial cell (PMVEC) injury. AIM: To determine its role in the tumor necrosis factor-alpha (TNF-α)-induced inflammation and apoptosis of PMVECs in vitro. We then conducted in vivo experiments to confirm the effect of SB203580-mediated p38 inhibition on SAP-ALI. METHODS: In vitro, PMVEC were transfected with mitogen-activated protein kinase kinase 6 (Glu), which constitutively activates p38, and then stimulated with TNF-α. Flow cytometry and western blotting were performed to detect the cell apoptosis and inflammatory cytokine levels, respectively. In vivo, SAP-ALI was induced by 5% sodium taurocholate and three different doses of SB203580 (2.5, 5.0 or 10.0 mg/kg) were intraperitoneally injected prior to SAP induction. SAP-ALI was assessed by performing pulmonary histopathology assays, measuring myeloperoxidase activity, conducting arterial blood gas analyses and measuring TNF-α, interleukin (IL)-1ß and IL-6 levels. Lung microvascular permeability was measured by determining bronchoalveolar lavage fluid protein concentration, Evans blue extravasation and ultrastructural changes in PMVECs. The apoptotic death of pulmonary cells was confirmed by performing a terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling analysis and examining the Bcl2, Bax, Bim and cle-caspase3 levels. The proteins levels of P-p38, NFκB, IκB, P-signal transducer and activator of transcription-3, nuclear factor erythroid 2-related factor 2, HO-1 and Myd88 were detected in the lungs to further evaluate the potential mechanism underlying the protective effect of SB203580. RESULTS: In vitro, mitogen-activated protein kinase (Glu) transfection resulted in higher apoptotic rates and cytokine (IL-1ß and IL-6) levels in TNF-α-treated PMVECs. In vivo, SB2035080 attenuated lung histopathological injury, decreased inflammatory activity (TNF-α, IL-1ß, IL-6 and myeloperoxidase) and preserved pulmonary function. Furthermore, SB203580 significantly reversed changes in the bronchoalveolar lavage fluid protein concentration, Evans blue accumulation, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling-positive cell numbers, apoptosis-related proteins (cle-caspase3, Bim and Bax) and endothelial microstructure. Moreover, SB203580 significantly reduced the pulmonary P-p38, NFκB, P-signal transducer and activator of transcription-3 and Myd88 levels but increased the IκB and HO-1 levels. CONCLUSION: p38 inhibition may protect against SAP-ALI by alleviating inflammation and the apoptotic death of PMVECs.

One new sesquineolignan, piperneolignan A (1), four new neolignans, piperneolignans B-E (2-5), and eight known compounds were isolated from the leaves of Piper betle (Piperaceae) collected from Myanmar. These new structures were determined by analysis of MS and NMR data, and the absolute configuration of piperneolignan A was elucidated by electronic circular dichroism (ECD) calculations. Piperneolignan A (1), piperneolignan B (2), hydroxychavicol (6), p-hydroxycinnamaldehyde (10), and diallylcatechol (13) possessed anti-inflammatory activity against nitric oxide (NO) production in lipopolysaccharide (LPS)-activated murine macrophage RAW 264.7 cells with IC50 values of 9.87, 45.94, 4.80, 26.40, and 40.45 µM, respectively, compared with the positive control NG-monomethyl-l-arginine (l-NMMA, IC50 = 33.84 µM). The two hydroxy groups in the structure of hydroxychavicol are essential for activity, and dimerization or trimerization of hydroxychavicol decreases activity.

BACKGROUND: Central Myanmar is located in the Indo-Burma biodiversity hotspot, and the Bamar people are the main ethnic group, which settled there over 1000 years ago. Despite being the core region of the country, central Myanmar has been ignored in previous ethnobotanical studies. Local healthy foods and knowledge are regarded as treasures for resource development and pharmaceutical drug discovery, and market surveys are a good strategy in ethnobotanical research. Thus, we collected and documented typical vegetables and local knowledge in local markets and then analysed the diversity and local knowledge of these vegetables. MATERIALS AND METHODS: Observations and interviews were used in the field study, and 10 markets and fairs were selected in central Myanmar. A total of 277 vegetable stalls or shops were visited. We compared the local knowledge we collected with selected important and typical herbal books on traditional Myanmar medicine. Quantitative analysis, including frequency of citation (FC), relative frequency of citation (RFC) and use value (UV), was used to assess the diversity and local knowledge of these vegetables. RESULTS: A total of 132 plant taxa from 47 botanical families and 116 genera were collected. Most (106 taxa, 80.3%) of these vegetables were cited by the informants as functional foods that had health benefits, while others were regarded as merely "good for health". The main health function of the vegetables was treating digestive problems. Sixty-four species were recorded in selected herbal books on traditional Myanmar medicine, and forty-seven taxa were not recorded in these books but were nonetheless used as healthy vegetables by local people. Twenty-eight species of vegetables were collected from wild places. CONCLUSION: The diversity and local knowledge of healthy vegetables in central Myanmar were rich. Nevertheless, the diversity of wild vegetables was seemingly relatively low. The possible reason was that we counted only the vegetables that were from entirely wild sources as "wild vegetables". The most frequently cited vegetables were commonly cultivated species, which reflects the fact that plants cultivated on a large scale comprise the major source of vegetables. Some lesser known vegetables could reflect the unique food culture of local people, but most of these were cited only a few times by the interviewees, which caused low UV and RFC rankings for them in the league table. In addition, future research should pay more attention to the food safety of these vegetables.

Two new 2H-pyran-2-one glucosides, cuscutarosides A (1) and B (2), and one new steroidal glucoside, 7ß-methoxy-ß-sitosterol 3-O-ß-glucopyranoside (3), together with 12 known compounds (4-15) were isolated from the whole plant of Cuscuta reflexa (Convolvulaceae) collected from Myanmar. The chemical structures of these new compounds were elucidated based on extensive spectroscopic analysis. The antiobesity activity of these isolates was evaluated using porcine pancreatic lipase (PPL), and the antiplatelet aggregation activity was screened using rabbit platelets induced by thrombin, platelet-activating factor (PAF), arachidonate (AA), or collagen. 7ß-Methoxy-ß-sitosterol 3-O-ß-glucopyranoside (3) showed weak PPL inhibitory activity. Cuscutaroside A (1), its acetylated derivative (1a), and scrophenoside B (8) showed weak inhibitory activity against rabbit platelet aggregation induced by collagen. Compound 1a also showed inhibitory activity against rabbit platelet aggregation induced by AA.
RESUMO
ETHNOPHARMACOLOGICAL RELEVANCE: People in Southern Xinjiang, China have been consuming medicinal teas for healthcare since before the ancient Silk Road markets began. Several pharmaceutical studies have illustrated the potential healthcare benefits of medicinal teas used in Southern Xinjiang, China. However, little information is available from the literature about the diversity of the species used and related traditional knowledge of these medicinal teas. AIMS OF THE STUDY: (i) create a comprehensive record of medicinal tea plant species (MTPS) and combinations used with related traditional knowledge for healthcare in Southern Xinjiang, China; (ii) assess safety of MTPS, and (iii) address conservation status for sustainable use of MTPS. MATERIALS AND METHODS: We employed both field and market surveys from 2014 to 2019 in 10 counties/cities and four main medicinal tea markets by using semi-structured interviews. We interviewed 236 informants and 70 medicinal tea shop vendors. The commonly used MTPS were ranked by Frequency of Citation. Safety issues were assessed based on expert knowledge and with reference to the official list of Medicinal Plants Used as Food. Conservation implications of plant use were assessed as part of the interviews and this was cross referenced with official records. RESULTS: The surveys revealed 145 different plants from 65 families used for making medicinal teas, expanding the list of known Chinese herbal tea species from 782 to 884. Leguminosae, Rosaceae, Lamiaceae and Apiaceae were dominant families. Herbs (60.7%, 88 species) were the most commonly used plant types; fruits (23.1%, 50 species) and seeds (22.2%, 48 species) were commonly used parts. Nearly half (42.1%) of the plant species were introduced from abroad. Respondents reported more than 50 types of healthcare uses of medicinal teas. Tonic (13.7%, 71 species) and promoting digestion (9.6%, 50 species) were the most frequently mentioned healthcare uses. The majority of commonly used plant species were spices (20 species, 50%) and aromatic plants (10 species, 25%). Cinnamomum cassia (L.) J.Presl, Piper longum L. Syzygium aromaticum (L.) Merr. & L. M. Perry and Gardenia jasminoides J. Ellis were the most cited species. High doses of Piper longum L., Crocus sativus L., Curcuma longa L, and Senna alexandrina Mill. May have negative health implications. Assessments of conservation status and sustainable use of tea species indicate that wild harvesting of Nardostachys jatamansi (D. Don) DC. and Pterocarpus indicus Willd. Should be controlled and cultivation technologies should be improved. CONCLUSIONS: We found high plant species diversity and rich traditional knowledge of medicinal teas used in Southern Xinjiang, China. The traditional healthcare uses of some of the medicinal teas are also supported by pharmaceutical evidence. Others should be investigated further. Conservation pressures exist for commonly used wild species. China's 'Healthy China 2030' policy should do more to take traditional cultural practices into account. In doing so, both local and national government agendas may seek to promote sustainable harvest and to protect traditional knowledge so that this cultural heritage continues to serve human well-being into the future.

Two new amides (E)-N-cinnamoyl-2-methoxypiperidine (1) and (R)-1-(2-oxopyrrolidin-3-yl)-5,6-dihydropyridin-2(1H)-one (2), four new amide glucosides, retrofractosides A-D (3-6), and two new phenylpropanoid glucosides, retrofractosides E (7) and F (8), together with 24 known compounds (9-32) were isolated from the fruits of Piper retrofractum. The chemical structures of these new compounds were elucidated based on extensive spectroscopic analysis. All of these isolates (1-32) were evaluated for inhibitory activity against mouse platelet aggregation induced by the peptide AYPGKF-NH2. (E)-N-(Tetrahydro-2H-pyran-2-yl)cinnamamide (9) showed a weak inhibitory effect, with an inhibition ratio of 52.0% at a concentration of 150 µM.
RESUMO
We aimed at reporting the chemical constituents and antimicrobial activities of Leea aequata L., a traditional folk medicine used in Myanmar for the treatment of wounds and skin diseases. A new neolignan, (7S,8R)-9'-O-acetylcedrusin (1), a new lactam, (3S,4S)-4-chloro-3-hydroxypiperidin-2-one (2), along with 21 known compounds, including five lignans (3-7), four flavonoid glycosides (8-11), and others (12-23), were isolated from the ethanoic extract of the aerial parts of L. aequata. The structures of the new compounds were determined by NMR, MS, and ECD spectra. For all the antimicrobial tests of the 23 compounds, only 3,4,5-trihydroxybenzoic acid ethyl ester (17) showed weak inhibitory activities against Escherichia coli and Salmonella enterica subsp. enterica.
RESUMO
Climate change may impact the distribution of species by shifting their ranges to higher elevations or higher latitudes. The impacts on alpine plant species may be particularly profound due to a potential lack of availability of future suitable habitat. To identify how alpine species have responded to climate change during the past century as well as to predict how they may react to possible global climate change scenarios in the future, we investigate the climatic responses of seven species of Meconopsis, a representative genus endemic in the alpine meadow and subnival region of the Himalaya-Hengduan Mountains. We analyzed past elevational shifts, as well as projected shifts in longitude, latitude, elevation, and range size using historical specimen records and species distribution modeling under optimistic (RCP 4.5) and pessimistic (RCP 8.5) scenarios across three general circulation models for 2070. Our results indicate that across all seven species, there has been an upward shift in mean elevation of 302.3 m between the pre-1970s (1922-1969) and the post-1970s (1970-2016). The model predictions suggest that the future suitable climate space will continue to shift upwards in elevation (as well as northwards and westwards) by 2070. While for most of the analyzed species, the area of suitable climate space is predicted to expand under the optimistic emission scenario, the area contracts, or, at best, shows little change under the pessimistic scenario. Species such as M. punicea, which already occupy high latitudes, are consistently predicted to experience a contraction of suitable climate space across all the models by 2070 and may consequently deserve particular attention by conservation strategies. Collectively, our results suggest that the alpine high-latitude species analyzed here have already been significantly impacted by climate change and that these trends may continue over the coming decades.
RESUMO
BACKGROUND: Thoracolumbar spine (TLS) fractures are commonly associated with the young healthy population, with its risk factors including both high-energy traumas and neurological deficit. The underlying mechanisms of traditional Chinese medicine (TCM) and TLS fractures have been explored. Therefore, our prospective study was conducted in order to explore the beneficial effects of TCM fumigation "Bone-healing Powder" method in both postoperative pain as well as the recovery of the patient's neurological function following healing from their traumatic TLS fractures. METHODS: Patients dealing with traumatic TLS fractures were randomly assigned into both the control and the intervention groups based on whether or not they received prior TCM fumigation in addition to any and all conventional therapy. Imaging indexes, including height of the injured vertebra (%), Cobb angle (°), horizontal displacement (%), compression area (%), sagittal diameter (%), and degree of both the swelling and pain regarding the fractures were observed and recorded both before and after the treatment for proper progression documentation. The neurological function was evaluated according to American Spinal Injury Association (ASIA) classification in order to investigate whether TCM fumigation "Bone-healing Powder" could affect the recovery of the patient's neurological function. RESULTS: Following the treatment as well as 1 year after its completion, patients who received TCM fumigation presented a higher height of their previously injured vertebra (%) and sagittal diameter (%), while a lower Cobb angle (°), horizontal displacement (%), and compression area (%) than those who were part of the conventional therapy group. A week posttreatment, patients that received TCM fumigation also showed no signs of swelling or mild pain. One year following the treatment, patients receiving TCM fumigation demonstrated an improved neurological function. CONCLUSION: These findings help to indicate that TCM fumigation "Bone-healing Powder" reduces the degrees of postoperative pain and swelling, and effectively improves recovery of the neurological function of those patients with traumatic TLS fractures, proving its worth as a clinical method in treatment.

ETHNOPHARMACOLOGICAL RELEVANCE: Herbal teas have long been consumed by Chinese people for preventive and/or therapeutic healthcare. Although herbal teas are widely consumed by many cultural groups in different regions of China, no thorough review has been undertaken to assess the diversity of the country's herbal tea usage. This literature review, complemented by a quantitative survey in an important tea market in Kunming, begins to fill this knowledge gap. AIMS OF THE STUDY: The study aims to summarize the current knowledge of plant species used as herbal teas by different cultural groups in different regions of China, with a focus on the teas' perceived traditional healthcare functions, related phytochemical/pharmaceutical research, and safety issues. MATERIALS AND METHODS: The study involved a comprehensive literature review and a market survey. The literature review was based on published ethnobotanical studies of herbal teas in China. We searched the Web of Science™, ELSEVIER, the China National Knowledge Infrastructure (CNKI) and the China Science and Technology Journal Database to locate relevant studies (including journal articles, Masters/PhD dissertations and books) that were published before March 2017. A species list was compiled based on the review and supplemented with information retrieved from the Scifinder database (https://scifinder.cas.org) and the Chinese Pharmacopoeia (2010). A Use Value Index was employed for ranking the most cited species. Based on the 29 most cited species, we discussed the current research status in relation to healthcare benefits and safety concerns of herbal teas in China. To better understand the current status of the herbal tea market in China, we also surveyed 136 tea vendors at the Xiongda Tea Market in Kunming. Information gathered from the survey included the species sold, the sale prices and the form of the herbal tea product. RESULTS: The literature identified 759 plant species used as herbal tea in China and the market survey identified an additional 23 species. Most of the species used were from the Leguminosae, Compositae and Lamiaceae families. Twenty two provinces and fourteen ethnic minority groups have records on the consumption of herbal teas. Southern China uses up to 82% of the total species, and 211 out of 759 species are used by minority groups. Thirty categories of traditional healthcare functions are linked with herbal teas, with clearing away heat, relieving toxicity and suppressing cough being the most important functions. There is phytochemical/pharmaceutical evidence to support the claimed healthcare benefits of some Chinese herbal teas. Although Chinese herbal teas are generally safe to consume, overdoses of some herbal teas and some unapproved mixtures of species may cause health risks. Based on our market survey, the prices of most herbal teas range between 100 and 200 RMB (US$15-30) per kg. CONCLUSIONS: A rich array of herbal tea species with various traditional healthcare functions have long been used in China, and as such there is a huge market potential for Chinese herbal teas. More pharmaceutical/phytochemical research is needed to assess a wide range of perceived healthcare benefits of Chinese herbal teas. Our research highlights the need to study herbal teas through an ethnopharmacological perspective and by employing a holistic approach, which requires greater consideration of traditional knowledge in the pharmacological research design. Product safety and sustainability issues should also be considered, so the traditional applications of herbal teas can be transformed to efficient health boosting functional products.

PREMISE OF THE STUDY: Novel and cost-effective microsatellite markers were developed to explore the population genetics, biogeographic structure, and evolutionary history of the prized Euro-Asian wild edible ectomycorrhizal fungus Tricholoma matsutake (Tricholomataceae). METHODS AND RESULTS: Eighteen new polymorphic simple sequence repeat loci, detected from a microsatellite-enriched genomic library, were used to characterize 131 individuals from eight T. matsutake populations. The number of alleles ranged from two to 10, with averages of 1.42 to 3.22. Levels of observed and expected heterozygosity ranged from 0.00-1.00 and from 0.00-0.83, with mean values of 0.21 and 0.26, respectively. In total, 50% of the loci showed interspecific transferability and polymorphism in the related species T. equestre. CONCLUSIONS: These newly developed markers will aid research into the genetic diversity and population structure of T. matsutake. They can also be used in other species of Tricholoma.
