Abstract Dendrobium nobile is a traditional Chinese medicine and functional food in China, with anti-aging, immunity-enhancing, glucose-lowering and lipid-lowering health functions. In recent years, the research value of D. nobile has attracted the attention of more and more experts and scholars. Today, phytochemical investigation of the stems of Dendrobium nobile Lindl., led to the isolation of five sesquiterpene glycosides, including dendromoniliside D (1), dendronobiloside A (2), dendronobiloside C (3), dendronobiloside D (4), dendroside G (5) and their α-amylase and α-glycosidase inhibitory activities were also investigated. Among them, dendromoniliside D (1), dendroside G (5) were first isolated from D. nobile. And dendronobiloside A (2) and dendronobiloside C (3) exhibited better inhibitory activity against α-glycosidases, respectively. In the case of α-amylase inhibition, dendroside G (5) has a relatively good effect. These results suggest that sesquiterpene glycosides of D. nobile have potential hypoglycemic activity and deserve further research and development.

Abstract OATP1A4 is an important member of the family of organic anion transporting polypeptides (OATPs), which is generally thought to mediate cellular uptake of endogenous and exogenous substances, such as bile acids, drugs and environmental toxins. Recent studies have found that Oatp1a4 plays an important role in drug passage through the blood-brain barrier and is expected to be an important target for drugs used to treat central diseases. Oatp1a4 has also been associated with various diseases such as cholestasis. differences in Oatp1a4 across age and sex have also become an area of concern for precision drug administration. Therefore, this paper presents a systematic review of Oatp1a4 expression in drug transport and various physiopathological states.

Abstract Yanlishuang Pills is a kind of traditional Chinese medicine used to treat pharyngitis widely. In this study, we used gas chromatography tandem mass spectrometry (GC-MS) to establish a method for the fingerprint and quantitative analysis of the four major components of Yanlishuang Pills, which can provide a more reliable method for its quality control. We used the software “Chromatographic Fingerprint Similarity Evaluation System for Traditional Chinese Medicine”, version A, 2004, to obtain fingerprint using the averaging method with a time width of 0.1. The peak with the largest peak area was used as the reference peak to determine the shared peaks and generate the common pattern. Then the main components of the Yanlishuang Pills were identified and their contents were determined in GC-MS SIM mode using internal standard method.The fingerprint established by GC-MS were reproducible, and a total of 18 common peaks were identified in the fingerprint of 13 batches of samples, and the similarity of the fingerprint of each batch of samples was above 0.99. The concentrations of camphor, menthone, borneol and menthol of the four main ingredients of the Yanlishuang Pills were linearly well within the range of 25.13-150.78 μg/mL (r = 0.9995), 28.77-172.62 μg/mL (r = 0.9991), 299.70-1798.20 μg/mL (r = 0.9997), 121.98-731.88 μg/mL (r = 0.9997), and the average recoveries were 102.02% (RSD of 1.3%), 96.10% (RSD of 1.0%), 102.71% (RSD of 1.3%), 102.58% (RSD of 1.1%), respectively, with good precision, reproducibility, and stability within 16 h. The camphor content of the 13 batches of samples was 5.6025-8.3662 mg/g, menthone content was 4.7871-5.8936 mg/g, borneol content was 88.0034-133.0969 mg/g and menthol was 40.2017-61.9466 mg/g. The fingerprints of the Yanlishuang Pills established by GC-MS were characterized by a common pattern, and the simultaneous determination of camphor, menthone, borneol and menthol in the Yanlishuang Pills was rapid, simple and accurate. In conclusion, the determination of the content of multiple ingredients combined with fingerprinting can provide a more comprehensive control of the quality of Yanlishuang Pills.

Abstract: Blumea balsamifera is a very famous medicinal plant and functional tea in many countries of Asia. Ainaxiang tablets are a preparation consisting of flavonoids from B. balsamifera. Today, a high performance liquid chromatography method was developed for simultaneous quantification of 15 flavonoids in Ainaxiang Tablets. The analysis was performed on a Kromasil C18 column (250 × 4.6 mm, 5 µm) with a binary gradient mobile phase of acetonitrile and 0.2% aqueous acetic acid. The method was validated in terms of linearity, sensitivity, stability, precision and accuracy. It was found that this method had linearity with R2 at 0.9992- 0.9999 in the test range of 0.15-276.40 µg/mL. The limit of detection (LOD) and limit of quantification (LOQ) for 15 tested reference compounds were 0.01-0.28µg/mL and 0.02 - 0.55µg/mL, respectively. The relative standard deviations (RSD%) for intra-day and inter-day repeatability were not more than 3.18%. The analyzed samples were stable for at least 18 h. The spike recoveries for 15 analyzed samples were 106.17 - 95.02%. The results suggested that this newly developed HPLC method could be used for quantitative analysis of flavonoids in Ainaxiang Tablets and its raw materials.

Abstract Gynostemma pentaphyllum is a functional food that is commercially available worldwide. Triterpenoid saponins are the main active components in Gynostemma pentaphyllum, which are usually hydrolyzed into triterpene sapogenins in organisms to play a pharmacological role. Gypensapogenin D is a triterpene sapogenins with the highest content in the hydrolysate of gypenoside. In addition, it was found that Gypensapogenin D had a certain inhibitory effect on α-glucosidase. In view of the poor solubility of Gypensapogenin D, which affects its bioavailability, Gypensapogenin D was prepared as a liposomal formulation in this paper, which provides valuable data for the later in-depth study and drug development and utilization of this compound. worldwide role gypenoside addition αglucosidase. αglucosidase α glucosidase. glucosidase α-glucosidase bioavailability paper indepth depth compound

Abstract Dendrobium nobile is a traditional Chinese medicine and nourishing food in China. Alkaloids and sesquiterpene glycosides are the two main active ingredients in D. nobile. The previous reports showed that alkaloids and sesquiterpene glycosides have the same upstream biosynthetic pathway, starting from sesquiterpene components, part of which is converted to sesquiterpene glycosides by the action of UDP-glycosyltransferase, and part of which is further synthesized to alkaloids. Therefore, sesquiterpene UDP-glycosyltransferases play an important role in the biosynthesis of alkaloids and sesquiterpene glycosides in D. nobile. In this study, the key glycosyltransferase genes in sesquiterpene glycosylation in D. nobile were explored, predicted and validated by transcriptome technology. China D pathway components UDPglycosyltransferase, UDPglycosyltransferase UDP glycosyltransferase, UDP-glycosyltransferase Therefore UDPglycosyltransferases glycosyltransferases study explored technology

Abstract Background: Tocilizumab (TCZ), a humanized monoclonal antibody against the interleukin-6 receptor, has been proven to be a safe and effective treatment for rheumatoid arthritis (RA). Because RA is a heterogenous disease and patient response to treatments can vary, identifying characteristics that predict which patients are more likely to respond to TCZ is important for optimal patient care. Serum levels of C-X-C motif chemokine ligand 13 (CXCL13) and soluble intercellular adhesion molecule-1 (sICAM-1) have been associated with response to TCZ in patients with RA. Objectives: To evaluate the association of CXCL13 and sICAM-1 with disease activity and response to TCZ in patients with early RA and those with inadequate response to disease-modifying antirheumatic drugs (DMARD-IR). Methods: Baseline and week 24 serum CXCL13 and sICAM-1 levels were measured using available patient samples from the FUNCTION (early RA) and LITHE (DMARD-IR) trials. Correlations between CXCL13 and sICAM-1 levels and Disease Activity Score in 28 joints calculated with erythrocyte sedimentation rate (DAS28-ESR) at baseline and between change in CXCL13 and sICAM-1 and change in DAS28-ESR at week 24 were estimated. CXCL13 and sICAM-1 changes from baseline to week 24 were compared between treatment arms. The effects of TCZ treatment and baseline DAS28-ESR, CXCL13 and sICAM-1 levels on DAS28-ESR remission and 50% improvement per the American College of Rheumatology (ACR50) response at week 24 were determined. Results: Overall, 458 patients from FUNCTION and 287 patients from LITHE were included. Correlation of baseline serum CXCL13 and sICAM-1 levels with DAS28-ESR was weak to moderate. CXCL13 and sICAM-1 levels decreased significantly at week 24 in TCZ-treated patients in both the early-RA and DMARD-IR populations. CXCL13 and sICAM-1 changes correlated moderately to weakly with DAS28-ESR changes at week 24 in both populations. The treatment regimen, but not baseline CXCL13 and sICAM-1 levels, had a significant effect on the likelihood of DAS28-ESR remission and ACR50 response. Conclusions: Although CXCL13 and sICAM-1 are modestly associated with RA disease activity, they do not predict response to TCZ in all RA populations.
