Anti-obesity and Gut Microbiota Modulation Effect of Astragalus Polysaccharides Combined with Berberine on High-Fat Diet-Fed Obese Mice / 中国结合医学杂志

OBJECTIVE@#To investigate whether astragalus polysaccharides (APS) combined with berberine (BBR) can reduce high-fat diet (HFD)-induced obesity in mice.@*METHODS@#Except for normal mice, 32 HFD-induced obese mice were randomized into HFD, APS (1,000 mg/kg APS), BBR (200 mg/kg BBR), and APS plus BBR (1,000 mg/kg APS plus 200 mg/kg BBR) groups, respectively. After 6-week treatment (once daily by gavage), the obesity phenotype and pharmacodynamic effects were evaluated by histopathological examination of epididymal fat, liver, and colon using hematoxylin-eosin staining and serum biochemical analyses by an automated chemistry analyzer. The feces were collected at the 12 th week, and taxonomic and functional profiles of gut microbiota were analyzed by 16S ribosomal ribonucleic acid (16S rRNA) sequencing.@*RESULTS@#Compared with HFD group, the average body weight of APS plus BBR group was decreased (P<0.01), accompanied with the reduced fat accumulation, enhanced colonic integrity, insulin sensitivity and glucose homeostasis (P<0.05 or P<0.01). Importantly, APS combined with BBR treatment was more effective than APS or BBR alone in improving HFD-induced insulin resistance (P<0.05 or P<0.01). 16S rRNA sequence-based analysis of fecal samples demonstrated that APS combined with BBR treatment exhibited a better impact on HFD-induced gut microbiota dysbiosis, exclusively via the enriched abundances of Bacteroides, which corresponded to the large increase of predicted bacterial genes involved in carbohydrate metabolism.@*CONCLUSION@#APS combined with BBR may synergistically reduce obesity and modulate the gut microbiota in HFD-fed mice.

Study on the material basis of cold and hot properties of traditional Chinese medicines in Lamiaceae based on pattern recognition / 药学学报

To study the material basis of cold and hot properties of traditional Chinese medicines (TCMs) in Lamiaceae and to establish a cold and hot properties identification model, a database of material components of TCMs in Lamiaceae was established. A three-level classification system of material components was used to obtain the material basis of cold and hot properties of the Lamiaceae family by using data mining methods such as frequency analysis, association rule analysis, logistic regression, and feature selection. Several identification models were established to recognize the cold and hot properties. The chi-square test results showed that the material composition ratios of cold and hot properties were significantly different at the first-level, second-level, and third-level classification (P < 0.05), and the differences varied as the levels of substance classification changed. The average coefficients of variation were 42.30%, 79.07%, and 91.51% at the first-level, second-level, and third-level classification levels, respectively. In other words, in terms of the percentage differences in material composition ratio, the first-level was smaller than the second-level, and the second-level was smaller than the third-level. The results of the association rule analysis showed that under the third-level classification, there were many effective association rules, and 27 core groups and 34 specific groups of chemical components were obtained based on these rules. 15 decisive groups were obtained from the feature selection results. Multinomial logistic regression analysis was used to successfully establish a cold and hot properties identification model with an overall accuracy of 89%. The material basis of cold and hot properties of TCMs in Lamiaceae is different and intersect with each other. Twenty-seven groups of chemical components, such as bicyclic diterpenes, are the core groups of cold and hot properties, of which 15 groups are the decisive groups. The cold and hot properties are often characterized by the interaction of multiple classes of substances, and a single class of substances often cannot be used to characterize the properties. The organic combination of multiple classes of substances is the material basis of cold and hot properties.

Clinical application value of Huanglian Jiedu Pills in improving syndrome of excess heat and fire toxin based on phase Ⅱ clinical trial study on plasma ATP, 4-HNE, and ACTH levels / 中国中药杂志

A randomized, double-blind, placebo-controlled, multi-center phase Ⅱ clinical trial design was used in this study to recruit subjects who were in line with the syndrome of excess heat and fire toxin, and were diagnosed as recurrent oral ulcers, gingivitis, and acute pharyngitis. A total of 240 cases were included and randomly divided into a placebo group and a Huanglian Jiedu Pills group. The clinical efficacy of Huanglian Jiedu Pills in treating the syndrome of excess heat and fire toxin was evaluated by using the traditional Chinese medicine(TCM) syndrome scale. Enzyme-linked immunosorbent assay(ELISA) was used to determine and evaluate the levels of adenosine triphosphate(ATP), 4-hydroxynonenal(4-HNE), and adrenocorticotropic hormone(ACTH) in plasma of the two groups before and after administration and to predict their application value as clinical biomarkers. The results showed that the disappearance rate of main symptoms in the Huanglian Jiedu Pills group was 69.17%, and that in the placebo group was 50.83%. The comparison between the Huanglian Jiedu Pills group and the placebo group showed that 4-HNE before and after administration was statistically significant(P<0.05). The content of 4-HNE in the Huanglian Jiedu Pills group decreased significantly after administration(P<0.05), but that in the placebo group had no statistical significance and showed an upward trend. After administration, the content of ATP in both Huanglian Jiedu Pills group and placebo group decreased significantly(P<0.05), indicating that the energy metabolism disorder was significantly improved after administration of Huanglian Jiedu Pills and the body's self-healing ability also alleviated the increase in ATP level caused by the syndrome of excess heat and fire toxin to a certain extent. ACTH in both Huanglian Jiedu Pills group and placebo group decreased significantly after administration(P<0.05). It is concluded that Huanglian Jiedu Pills has a significant clinical effect, and can significantly improve the abnormal levels of ATP and 4-HNE in plasma caused by the syndrome of excess heat and fire toxin, which are speculated to be the effective clinical biomarkers for Huanglian Jiedu Pills to treat the syndrome of excess heat and fire toxin.

Portulaca oleracea extract reduces gut microbiota imbalance and inhibits colorectal cancer progression via inactivation of the Wnt/ß-catenin signaling pathway.

BACKGROUND: Portulaca oleracea is a known medicinal plant with antioxidant, anti-inflammatory, and anticancer activities, and it may also function an important role in colorectal cancer (CRC). PURPOSE: We probed into study the critical function of Portulaca oleracea extract (POE) in CRC and the related downstream factors. METHODS: Azoxymethane (AOM) and dextransodiumsulfate (DSS) were used to induce mouse models of CRC, which were then administered different doses of POE to evaluate the therapeutic effects of POE on CRC. Diversity, abundance, and function of gut microbiota were analyzed. Moreover, the potential molecular targets of POE inhibiting CRC development were determined. Expression of c-Myc and cyclin D1 as well as CRC cell proliferation and apoptosis was detected. RESULTS: POE treatment inhibited AOM/DSS-induced CRC development in mice and ameliorated gut microbial imbalance. Bioinformatic analysis revealed marked differences in the gut microbiota between CRC samples and normal samples and that 20 differential microbiota may be involved in CRC development through the Wnt signaling pathway. Additionally, c-Myc and cyclin D1 were identified to be the key downstream target genes of the Wnt/ß-catenin signaling pathway. In vitro data revealed that POE played a suppressive role in the proliferation of CRC cells by reducing the expression of c-Myc and cyclin D1 and inactivating the Wnt/ß-catenin signaling pathway. CONCLUSION: This study underlines that POE reduces gut microbiota imbalance and inhibits CRC development and progression via inactivation of the Wnt/ß-catenin signaling pathway and downregulation of c-Myc and cyclin D1 expression, which is expected to be a potential biomarker for CRC.

Deficits in auditory and visual steady-state responses in adolescents with bipolar disorder.

BACKGROUND: Many aspects of steady-state responses of the brain remain unclear in bipolar disorder (BD) due to the small number of auditory steady-state response (ASSR) studies and the lack of steady-state visual evoked potential (SSVEP) studies on this complex disorder. Therefore, we assessed the patterns of SSVEP and ASSR in adolescents with BD during an active task to detect possible deficits in these important brain responses compared to normal subjects. METHODS: 27 adolescents with BD and 30 healthy adolescents were assessed in this study. The blinking background of the monitor presented at 15 Hz and the tone signal stimulation at 40 Hz evoked SSVEPs and ASSRs, respectively. The phase and amplitude of the steady-state responses were calculated in the auditory and visual conditions. RESULTS: Patients exhibited a substantially worse performance in the motor control inhibition task during both auditory and visual modalities. Patients showed increased SSVEP amplitude and phase in the frontal region compared to control adolescents. Also, patients exhibited decreased ASSR amplitude in the prefrontal and increased ASSR amplitude in the right-frontal and centro-parietal areas compared to healthy adolescents. CONCLUSIONS: impairments in the production and preservation of SSVEP and ASSR are evident in BD, implicating abnormalities in visual and auditory pathways. Neurophysiological deficits and worse performance in BD adolescents may imply that visual and auditory pathways cannot well transfer the pertinent information from arriving sensory data to the visual and auditory cortices, and the frontal cortex cannot well integrate incoming signals into a unified and coherent perceptual action.

MeJA regulates the accumulation of baicalein and other 4'-hydroxyflavones during the hollowed root development in Scutellaria baicalensis.

The dried roots of Scutellaria baicalensis are important traditional Chinese medicine used to treat liver and lung inflammation. An anomalous structure, hollowed root, was discovered in perennial cultivated Scutellaria baicalensis. The presence of the hollow may change the contents of bioactive metabolites, such as baicalein, and other 4'-hydroxyflavones in Scutellaria baicalensis roots, but the relationship between the hollowed root and bioactive metabolite contents is poorly understood. In this study, we identified the anatomical structure of the hollowed root and detected differentially accumulating flavonoid metabolites and enzymes related to 4'-hydroxyflavone biosynthesis in 3-year-old roots with a hollow. We confirmed that methyl jasmonate (MeJA) induced the accumulation of 4'-hydroxyflavones and the expression of enzymes related to 4'-hydroxyflavone biosynthesis in hydroponically cultured Scutellaria baicalensis roots. The development of the hollowed root were divided into 4 stages. The 4'-hydroxyflavone contents and expression of enzymes related to 4'-hydroxyflavone biosynthesis increased synchronously with the content of MeJA during the development of hollowed root. Pathogen and programed-cell-death related genes were induced during hollowed root development. Taken together, our results provide novel insight into the importance of MeJA in the development of hollowed root and the accumulation of 4'-hydroxyflavones in Scutellaria baicalensis roots. Our results suggest that a pathogen and senescence are the two major causes for the development of hollowed root in Scutellaria baicalensis roots.

Rhizosphere Exudate-mediated Synergistic Harm of Soil Microorganisms to Medicinal Plants in Continuous Cropping / 中国实验方剂学杂志

Continuous cropping obstacle is the bottleneck of medicinal plant cultivation, which seriously affects the quality and yield of medicinal materials. The research on the mechanism of continuous cropping obstacle has evolved from soil physical and chemical properties and allelopathy in the 1970s to the changes of rhizosphere microenvironment and plant response mechanism at present. According to the available studies in this field and our previous research work, we systematically analyzed the mechanism of rhizosphere exudate-mediated microbial community reconstruction in the soil of the medicinal plants in continuous cropping. Specifically, rhizosphere exudates, providing the carbon source and energy for microbial growth, act as inducers or repellents to induce microbial growth or transfer, thereby changing the physicochemical properties (such as acidity) of rhizosphere soil and further altering the structure of rhizosphere microbial community. Further, we comprehensively discussed the ways of synergism between rhizosphere exudates and soil microorganisms in causing harm to the medicinal plants in continuous cropping. That is, rhizosphere exudates mediate the infection of the rhizosphere by pathogenic microorganisms, increase the susceptibility of the nearby plants, inhibit the defense of the host plants, and protect the pathogens to occupy the dominant niche. The synergistic interaction results in the release of more pathogenic factors such as mycotoxins by rhizosphere pathogens, enhanced toxicity of rhizosphere allelochemicals, and deterioration of soil physical and chemical properties. This paper summarizes the role of interaction between rhizosphere exudates and soil microorganisms in the formation of continuous cropping obstacles, aiming to provide a new research idea for revealing the formation mechanism as well as the theoretical support for overcoming continuous cropping obstacles of medicinal plants.

Visualizing the spatial distribution and alteration of metabolites in continuously cropped Salvia miltiorrhiza Bge using MALDI-MSI / 药物分析学报

Salvia miltiorrhiza Bge(SMB)has long been used in traditional Chinese medicine to treat cardiovascular and cerebrovascular diseases.Growing clinical usage has led to a huge demand for artificial planting of SMB.Thus,continuous cropping of SMB is an important challenge that needs to be addressed.Contin-uous cropping can alter the metabolic profile of plants,resulting in poor growth and low yield.In this study,we tried to image the spatial location and variation of endogenous metabolites in continuously cropped SMB using matrix-assisted laser desorption/ionization mass spectrometry imaging(MALDI-MSI).Spatially resolved expressions of tanshinones,salvianolic acids,polyamines,phenolic acids,amino acids,and oligosaccharides in normal and continuously cropped SMB roots were compared.The ex-pressions of dihydrotanshinone Ⅰ,tanshinone Ⅱ A,dehydromiltirone,miltirone,dehydrotanshinone ⅡA,spermine,salvianolic acid B/E,tetrasaccharide,and pentasaccharide in continuously cropped SMB roots were much lower than those in normal roots.There was little difference in the expressions of caffeic acid and salvianolic acid A in normal and continuously cropped SMB roots.Ferulic acid was more widely distributed in xylem of normal SMB but strongly expressed in xylem,phloem,and cambium of continuously cropped SMB.The spatially resolved metabolite information enhances our understanding of the metabolic signature of continuously cropped SMB and also provides insights into the metabolic ef-fects of continuous cropping in other plants.

Research progress on pesticide residues of Panax notoginseng / 中国中药杂志

Panax notoginseng is a perennial Chinese medicinal plant, which has serious continuous cropping obstacles and is prone to a variety of diseases and insect pests during the growth process. At present, the prevention and control of pests and diseases is mainly carried out through chemical pesticides, and the consequent pesticide residues of P. notoginseng have attracted much attention. This study reviewed the types and detection methods of pesticide residues in P. notoginseng from 1981 to 2021, and compared the limits of pesticide residues in P. notoginseng in China and abroad to provide a reference for rational application of pesticides in P. notoginseng and quality control of medicinal materials, thereby promoting the sustainable development of the P. notoginseng industry in China. Currently, there are only 40 published papers on pesticide residues of P. notoginseng, which is indicative of a serious problem of insufficient research. At present, hundreds of pesticide residues in P. notoginseng can be detected simultaneously by using chromatography-tandem mass spectrometry. The pesticides detected have gradually changed from early prohibited ones, such as dichlorodiphenyl trichloroethane(DDT), benzene hexachloride(BHC), and parathion, to low toxic ones(e.g., dimethomorph, procymidone, propicona-zole, and difenoconazole). The dietary risk from pesticide residues in P. notoginseng is low, which would not cause harm to consu-mers. This study concluded that in the future, the development of the quality standard for pesticide residues of P. notoginseng should be actively carried out. To increase the pesticides used in actual production in the quality standard based on the existing ones and to guide farmers to use pesticides scientifically will be the focus of future work.

Research progress on pesticide residues of Panacis Quinquefolii Radix / 中国中药杂志

Panacis Quinquefolii Radix is the dry root of Panax quinquefolium, which is a perennial plant of Araliaceae. The plant has a long growth cycle and serious growth barrier problem, which leads to the use of pesticides. As a result, the pesticide residues in Panacis Quinquefolii Radix are arousing great concern. This paper reviews the research findings on the investigation, detection methods, content analysis and risk assessment of pesticide residues in Panacis Quinquefolii Radix since 1993, and compares the pesticide residue limit standards of different countries and regions. The pesticide residues in Panacis Quinquefolii Radix have been changing from organochlorines with high toxicity to triazines and triazoles with low toxicity. The pesticide residues are generally low, while the pollution of pentachloronitrobenzene and other pesticides still exist. The detection method has evolved from chromatography to chromatography-mass spectrometry. There are no reports of health risks caused by pesticide residues of Panacis Quinquefolii Radix. Pesticide residue is a major factor restricting the sound development of Panacis Quinquefolii Radix industry in China. Therefore, we suggest to improve the registration of pesticides applied to the plant, popularize mature ecological planting mode and supporting technology, and strengthen the research on the risk assessment and limit standard of pesticide residue in Panacis Quinquefolii Radix.

Objective:To explore the mechanism and compatibility characteristics of Baimai ointment （BMO） in the treatment of white vein disease from the network perspective based on system theory， so as to provide biological basis for its clinical application. Method:The chemical components and the corresponding candidate target spectra of BMO were obtained from The Encyclopedia of Traditional Chinese Medicine （ETCM） and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP）. According to the clinicopathological characteristics of white vein disease， focusing on four diseases/symptoms including neuropathic pain， inflammatory pain， chronic pain and lumbar disc herniation root neuralgia， the gene sets related to white vein disease were collected in Human Phenotype Ontology （HPO）， DisGeNET and other databases， then the interaction network of the targets of active components in BMO-gene sets related to white vein disease was constructed. On this basis， the hub network nodes were selected and enriched for exploring the mechanism of four functional groups of BMO in the treatment of white vein disease such as Huoxue Tongluo group （Curcumae Longae Rhizoma， Moschus， Tronae）， Xingqi Zhitong group （Myristicae Semen， Nardostachyos Radix et Rhizoma， Acori Calami Rhizoma）， Wenjing Sanhan Tongluo group （Zingiberis Rhizoma， Zanthoxyli Pericarpium， Caraway） and Jianpi Wenshen Qianggu group （Actinolite， Glycyrrhizae Radix et Rhizoma）. Result:The enriched pathways of the four functional groups in BMO were mainly distributed in three modules of nervous system function， inflammation-immune system regulation and body energy metabolism， and each module was connected by common target genes especially had its own focus. Among them， the regulation of nervous system function in Huoxue Tongluo group and Xingqi Zhitong group could be summarized as Huoxue Buqi and Xingshen Kaiqiao. Xingqi Zhitong group and Jianpi Wenshen Qianggu group were mainly used to promote the operation of Qi， promote blood metaplasia， enhance immunity and maintain the regulation of inflammation-immune system. Jianpi Wenshen Qianggu group and Wenjing Sanhan Tongluo group mainly regulated body energy metabolism by invigorating the spleen and supplementing Qi as well as warm-heat medicine. The whole formula focused on the multi-dimensional and multi-level mechanism of BMO in the intervention of white vein disease. Each functional group emphasized its respective characteristics in nervous system function， inflammation-immune regulation， and body energy metabolism. Two types of networks analysis models complemented and verified each other. Conclusion:BMO plays a role in the treatment of white vein disease mainly by regulating the function of nervous system， maintaining the balance of inflammation-immune system and interfering with energy metabolism. The relevant research results can provide reference for the in-depth exploration of the mechanism of BMO， and help to guide the clinical rational use of this preparation.
