RESUMO
Cadmium (Cd) toxicity severely limits plant growth and development. Moreover, Cd accumulation in vegetables, fruits, and food crops poses health risks to animals and humans. Although the root cell wall has been implicated in Cd stress in plants, whether Cd binding by cell wall polysaccharides contributes to tolerance remains controversial, and the mechanism underlying transcriptional regulation of cell wall polysaccharide biosynthesis in response to Cd stress is unknown. Here, we functionally characterized an Arabidopsis thaliana NAC-type transcription factor, NAC102, revealing its role in Cd stress responses. Cd stress rapidly induced accumulation of NAC102.1, the major transcript encoding functional NAC102, especially in the root apex. Compared to wild type (WT) plants, a nac102 mutant exhibited enhanced Cd sensitivity, whereas NAC102.1-overexpressing plants displayed the opposite phenotype. Furthermore, NAC102 localizes to the nucleus, binds directly to the promoter of WALL-ASSOCIATED KINASE-LIKE PROTEIN11 (WAKL11), and induces transcription, thereby facilitating pectin degradation and decreasing Cd binding by pectin. Moreover, WAKL11 overexpression restored Cd tolerance in nac102 mutants to the WT levels, which was correlated with a lower pectin content and lower levels of pectin-bound Cd. Taken together, our work shows that the NAC102-WAKL11 module regulates cell wall pectin metabolism and Cd binding, thus conferring Cd tolerance in Arabidopsis.

ObjectiveIn view of the standardization of clinical diagnosis and treatment of the acute abdomen and the inheritance of diagnosis and treatment experience of prestigious veteran traditional Chinese medicine(TCM) doctors, a diagnosis and treatment reasoning algorithm based on association rule mining under incomplete evidence(AMIE)+ random walk was proposed to provide information services and technical support for primary doctors by recommending personalized diagnosis and treatment plans based on medical records. MethodThe experience of diagnosis and treatment of acute abdomen of prestigious veteran TCM doctors and the text data of clinical diagnosis and treatment guidelines of integrated TCM and western medicine were collected to complete the task of knowledge extraction and construct acute abdomen knowledge graph based on Neo4j. On the basis of ontology-supported rule-based reasoning, the rule reasoning based on similar syndromes was used to expand the syndrome combinations whose Jaccard similarity was greater than the threshold in the syndrome recommendation results. The semantic path coverage algorithm was used to calculate the semantic similarity between the symptom nodes. The symptom nodes were divided into 10 categories, and the symptom nodes in the same category were extended. The random walk algorithm was used to search the symptom nodes connected with the syndrome, and the connection rules between the syndrome and symptom nodes were extended to realize the knowledge reasoning of AMIE+ random walk. ResultThe acute abdomen knowledge graph included 1 320 nodes and 2 464 relationships. According to the link prediction evaluation index of knowledge reasoning, the reasoning results of the three algorithms in the auxiliary diagnosis and treatment of acute abdomen were compared. The AMIE+ random walk algorithm complemented the knowledge graph by extending the similar syndrome connection rules and the syndrome-symptom connection rules. Compared with the knowledge reasoning algorithm based on ontology rules, the area under the curve (AUC) was 15.18% higher and the accuracy was 30.36% higher, which achieved more accurate and effective knowledge inference. ConclusionThis study used knowledge graph technology to visualize the diagnosis and treatment of acute abdomen with TCM and western medicine, assisting primary clinicians in intuitively viewing the diagnosis and treatment process and data relationship. The proposed diagnosis and treatment reasoning algorithm can realize the personalized diagnosis and treatment plan recommendation at the level of "disease-syndrome-diagnosis-treatment-prescription", which can assist primary doctors in disease diagnosis and treatment and clinical decision-making, contribute to the knowledge sharing and application of diagnosis and treatment experience and clinical guidelines of prestigious veteran TCM doctors, improve the level of primary clinical diagnosis and treatment, and promote the normalization and standardization of the diagnosis and treatment process of acute abdomen with integrated TCM and western medicine.
RESUMO
ObjectiveTo explore the mechanism of Cervi Cornu Pantotrichumin in the treatment of osteoarthritis by network pharmacology. MethodThe active ingredients and the corresponding targets of Cervi Cornu Pantotrichumin were screened out by a Bioinformatics Analysis Tool of Molecular mechANism of Traditional Chinese Medicine (BATMAN-TCM). The targets related to osteoarthritis were obtained through GeneCards and Online Mendelian Inheritance in Man (OMIM). The targets corresponding to the active ingredients and those related to osteoarthritis were intersected to reveal the common targets, and STRING was adopted to build a protein-protein interaction (PPI) network. DAVID was used for gene ontology (GO) annotation and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment on the anti-osteoarthritis targets of Cervi Cornu Pantotrichumin, and R x64 3.6.3 was employed to produce the advanced bubble charts of GO terms and KEGG pathways. Cytoscape 3.7.2 was used to establish the “Chinese medicinal herb-active ingredient-target-signaling pathway” network. In vitro experiments were performed to detect the viability of RAW 264.7 cells exposed to oxidative stress and the tumor necrosis factor (TNF)-α level in RAW 264.7 cells with inflammation under the treatment by Cervi Cornu Pantotrichumin. ResultA total of 20 active ingredients of Cervi Cornu Pantotrichum were obtained, of which ceramide, 6'-O-β-D-glucosylgentiopicroside, cerebroside, oleuropein, sphingomyelin, and cholesterol ferulate did not meet the screening conditions. Therefore, a total of 14 active ingredients were finally screened out, and 303 and 3 093 targets of active ingredients and osteoarthritis were respectively obtained. The two target sets were taken to intersect, which revealed 92 common targets. GO annotation and KEGG pathway enrichment showed that the targets were mainly involved in redox process, positive regulation of RNA polymerase Ⅱ promoter transcription, inflammatory response, protein synthesis, osteoclast differentiation, TNF signaling pathway, signaling pathways in cancer, mammalian target of rapamycin (mTOR) signaling pathway, mitogen-activated protein kinase (MAPK) signaling pathway, and cyclic adenosine monophosphate (cAMP) signaling pathway. The results of in vitro experiments showed that a certain concentration of protein in Cervi Cornu Pantotrichum significantly increased the viability of RAW 264.7 cells exposed to H2O2-induced oxidative damage (P<0.05, P<0.01) and reduced the level of TNF-α in the RAW 264.7 cells experiencing lipopolysaccharide (LPS)-induced inflammation (P<0.05). ConclusionBased on the network pharmacology method, the mechanism of the multi-component, multi-target and multi-pathway treatment of OA by antler antler was explained, and the anti-inflammatory and antioxidant activities of antler antler were confirmed, which provided theoretical guidance and scientific basis for further research on the treatment of OA by antler antler.
RESUMO
In this study, the putative genes involved in diterpenoid alkaloids biosynthesis in A. vilmorinianum roots were revealed by transcriptome sequencing. 59.39 GB of clean bases and 119,660 unigenes were assembled, of which 69,978 unigenes (58.48%) were annotated. We identified 27 classes of genes (139 candidate genes) involved in the synthesis of diterpenoid alkaloids, including the mevalonate (MVA) pathway, the methylerythritol 4-phosphate (MEP) pathway, the farnesyl diphosphate regulatory pathway, and the diterpenoid scaffold synthetic pathway. 12 CYP450 genes were identified. We found that hydroxymethylglutaryl-CoA reductase was the key enzyme in MVA metabolism, which was regulated by miR6300. Transcription factors, such as bHLH, AP2/EREBP, and MYB, used to synthesize the diterpenes were analyzed. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s13205-021-02646-6.
RESUMO
Due to their fascinating chemical structures and extensive pharmacological activities, polycyclic polyprenylated acylphloroglucinols(PPAPs) have become one of the current research hotspots of natural products. In particular, some of the PPAPs not only have novel non-traditional skeleton types, but also contain more unknown possible activities, which are of great significance for the development of lead compounds. The structure, source, biosynthetic pathway and pharmacological activities of PPAPs with non-traditio-nal skeleton types isolated and identified in recent years are reviewed, in order to provide references for further research on such compounds.

Due to its own internal laws of development, Chinese medicine (CM) seems more inclined to empirical medicine in a relatively long historical period. It is considered to be lacking objective and unified clinical practice guidelines (CPGs), and the difficulties in diagnosis and therapeutic effect evaluation comes with it, have restricted its further inheritance, development and international communication. Over the years, our research group has been committed to improving the standardization theory and methodology of CM, also perfecting relative techniques for further application, which are all based on the stratified evidence scoring method. We have already applied this method to 45 issued guidelines, including 5 national guidelines, 3 industrial guidelines, and 37 formulation/revision social organization guidelines. The stratified evidence scoring method has been recognized and used widely. It helps scholars and applicators to study, formulate, publish and popularize the acupuncture therapy clinical practice guidelines better, thus further promotes the development of acupuncture therapy.
RESUMO
OBJECTIVE@#The clinical symptoms of diarrhea-predominant irritable bowel syndrome (IBS-D) can be effectively improved by traditional Chinese medicine (TCM) treatment, based on the usage of specific therapies for different TCM syndromes. However, in the stage of diagnosis, the standard criteria for the classification of TCM syndrome were still deficient. Through serum metabolic profiling, this study aimed to explore potential biomarkers in IBS-D patients with different TCM syndromes, which can assist in diagnosis of the disease.@*METHODS@#Serum samples were collected from healthy controls (30 cases), IBS-D patients with Liver-Stagnation and Spleen-Deficiency syndrome (LSSD, 30 cases), Yang Deficiency of Spleen and Kidney syndrome (YDSK, 11 cases) and Damp Abundance due to Spleen-Deficiency syndrome (DASD, 22 cases). Serum metabolic profiling was conducted by ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. The potential biomarkers were screened by orthogonal partial least square-discriminate analysis, while metabolic pathways undergoing alterations were identified by pathway enrichment analysis in MetaboAnalyst 4.0.@*RESULTS@#Overall, 34 potential biomarkers were identified in LSSD group, 36 in YDSK group and 31 in DASD group. And the 13 metabolites shared by three groups were determined as the potential biomarkers of IBS-D. Glycerophospholipid metabolism was disturbed significantly in IBS-D patients, which may play a role in IBS-D through inflammation. What's more, three TCM syndromes have the specific potential biomarkers in glycerophospholipid metabolism.@*CONCLUSION@#The serum metabolomics revealed that different TCM syndrome types in IBS-D may have different metabolic patterns during disease progression and glycerophospholipid metabolism was one of the pathways, whose metabolism was disturbed differently among three TCM syndromes in IBS-D. Therefore, the specific potential biomarkers in glycerophospholipid metabolism of three TCM syndromes in IBS-D can serve as the objective indicators, which can facilitate the TCM-syndrome objective classification of IBS-D.

METHODS: In this study, general rabbit conditions, vascular histology, metabolites, and intestinal flora structures were analyzed. Integrated analysis of metabolomics and 16S rRNA sequencing were performed. All the rabbits were randomly divided into four groups. The rabbit model of atherosclerosis was established. The histopathological change in the common carotid artery was assessed by HE staining and the structural change in the flora by 16S rRNA sequencing. HPLC-TOF-MS and Agilent MPP 12.1 were integrated to identify and screen out differential metabolites. Correlational analyses of every differential metabolite with intestinal flora were integrated on Omicshare platform. RESULTS: Atherosclerotic rabbits showed obvious changes in general conditions, significant fibrous cap and necrotic center on carotid artery, abnormal intestinal bacteria structure, and metabolites levels. Electroacupuncture improved the conditions, reduced lipid deposition on the carotid artery wall, diversified intestinal flora, and normalized host metabolism. Integrated analysis showed that 149 altered metabolites were related to 22 intestinal flora, among which eight intestinal floras and 21 metabolites have relationships with atherosclerosis. CONCLUSION: Electroacupuncture can effectively reverse atherosclerosis through manipulating the structural feature of intestinal flora to influence the host metabolites. The possible mechanisms involved activating signal pathways through host metabolites or affecting the activity of cardiovascular-related enzymes, or regulating host lipid metabolism directly.
RESUMO
BACKGROUND: Dendrobii Officinalis Caulis (DC) is a well-known tonic herbal medicine worldwide and has favorable immunomodulatory activity. Various material specifications of DC are available in herbal markets, and DC is ingested by different edible methods. However, whether these specifications and edible methods are suitable or not remains unknown. METHODS: In this study, we evaluated the suitability of four material specifications (fresh stem, dried stem, fengdou and powder) and three edible methods (making tea, soup and medicinal liquor) based on holistic polysaccharide marker (HPM), the major polysaccharide components in DC. First, the HPMs were extracted from the four specifications of DC by the three edible methods in different conditions. Second, qualitative and quantitative characterization of the extracted HPMs was performed using high performance gel permeation chromatography (HPGPC). Third, immunomodulatory activities of the extracted HPMs were evaluated in vivo. RESULTS: The results showed that the HPMs were found to be quantitatively different from various specification of DC and edible methods. In vivo analysis indicated that the HPMs exerted positive effects on innate immune responses by increment in proliferation of splenocytes, secretion of IL-2 and cytotoxicity activity of NK cells. Moreover, the dosage amount of HPM should be defined as a certain range, but not the larger the better, for exerting strong immunological activities. CONCLUSION: According to the both chemical and biological results, fengdou by boiling with water for 4 h is the most recommended specification and edible method for DC.

Objective: To review the problems existing in the development and application of current electroacupuncture (EA) apparatuses, and provide reference for the development of EA apparatuses. Methods: Related literatures about EA apparatus were derived from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang) and Chongqing VIP Database (CQVIP) between 2013 and 2017. Literatures about the development of EA apparatuses and the application for experimental research and clinical treatment published in Chinese journals were retrieved, and the development and application of EA apparatuses were summarized. Results: Among the 107 selected literatures, 48 types of EA apparatuses were used, of which only 11 models could be found in the registration list and within the validity period. There was no registration information for the EA apparatus newly developed in the past 5 years. The EA parameters used in experimental research and clinical treatment in Chinese medicine were different, and the combination of stimulation parameters was diverse. Conclusion: At present, most of the new EA products are still in the experimental or research stage, and the transformation of results has not yet been achieved. Moreover, there is no unified standard for the use of EA apparatus and its stimulation parameters in experimental research and clinical treatment, which is not conducive to the standardization process of EA stimulation.
RESUMO
This study aims to investigate the possible mechanisms of electroacupuncture (EA) at PC6 to improve myocardial ischemia (MI) by regulating the cardiac transient outward potassium current channel (Ito). According to the random number table, the mice were divided into six groups of six mice each: control group, MI group, PC6, LU7 (Lieque-point), ST36 (Zusanli-point), and nonacupoint group. Mice in the control group were injected with saline (20 mg/kg, 24 hours interval), and the other ASIC3 -/- mice were injected subcutaneously twice with isoproterenol (ISO) (20 mg/kg, 24 hours interval). In the preexperiment, 5 mg/kg, 10 mg/kg, 20 mg/kg, and 30 mg/kg of ISO were used, and the results showed that 5 mg/kg and 10 mg/kg of ISO both could induce acute MI, but shorter duration of sustained MI. On the other hand, an injection of 30 mg/kg can make the mice experience arrhythmia or die immediately, and EA was operated at PC6, LU7, ST36 acupoints, and nonacupoint in the mice of PC6, LU7, ST36, and nonacupoint groups, respectively, after injecting twice. Then Western blotting techniques (Western Blot) were used to analyze the protein expressions of Kv1.4, Kv4.2, Kv4.3, and KchIP2. The results of this experiment showed that the protein expressions of Kv1.4, Kv4.2, Kv4.3, and KChIP2 in MI group were significantly lower than those in the control group (p < 0.01). Compared with MI group, the results of PC6, LU7, and ST36 groups obviously increased (p < 0.05). Furthermore, the expressions of PC6 group were higher than LU7 group and ST36 group (p < 0.05). And electrocardiogram's T-waves showed obvious pathological changes in the MI group compared to the control group (p < 0.01). After EA, the abnormal T-waves voltage of ECG in PC6, LU7, and ST36 groups was improved (p < 0.05). In addition, the rate change of PC6 group was larger than that of both LU7 and ST36 groups (p < 0.05). But the T-waves voltage of the nonacupoint group was not significantly different than that of the MI group (p > 0.05).
