"Component-target-efficacy" network analysis and experimental verification of Qingkailing Oral Preparation / 中国中药杂志

This study aims to explore the mechanism of Qingkailing(QKL) Oral Preparation's heat-clearing, detoxifying, mind-tranquilizing effects based on "component-target-efficacy" network. To be specific, the potential targets of the 23 major components in QKL Oral Preparation were predicted by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and SwissTargetPrediction. The target genes were obtained based on UniProt. OmicsBean and STRING 10 were used for Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment of the targets. Cytoscape 3.8.2 was employed for visualization and construction of "component-target-pathway-pharmacological effect-efficacy" network, followed by molecular docking between the 23 main active components and 15 key targets. Finally, the lipopolysaccharide(LPS)-induced RAW264.7 cells were adopted to verify the anti-inflammatory effect of six monomer components in QKL Oral Preparation. It was found that the 23 compounds affected 33 key signaling pathways through 236 related targets, such as arachidonic acid metabolism, tumor necrosis factor α(TNF-α) signaling pathway, inflammatory mediator regulation of TRP channels, cAMP signaling pathway, cGMP-PKG signaling pathway, Th17 cell differentiation, interleukin-17(IL-17) signaling pathway, neuroactive ligand-receptor intera-ction, calcium signaling pathway, and GABAergic synapse. They were involved in the anti-inflammation, immune regulation, antipyretic effect, and anti-convulsion of the prescription. The "component-target-pathway-pharmacological effect-efficacy" network of QKL Oral Preparation was constructed. Molecular docking showed that the main active components had high binding affinity to the key targets. In vitro cell experiment indicated that the six components in the prescription(hyodeoxycholic acid, baicalin, chlorogenic acid, isochlorogenic acid C, epigoitrin, geniposide) can reduce the expression of nitric oxide(NO), TNF-α, and interleukin-6(IL-6) in cell supernatant(P<0.05). Thus, the above six components may be the key pharmacodynamic substances of QKL Oral Preparation. The major components in QKL Oral Prescription, including hyodeoxycholic acid, baicalin, chlorogenic acid, isochlorogenic acid C, epigoitrin, geniposide, cholic acid, isochlorogenic acid A, and γ-aminobutyric acid, may interfere with multiple biological processes related to inflammation, immune regulation, fever, and convulsion by acting on the key protein targets such as IL-6, TNF, prostaglandin-endoperoxide synthase 2(PTGS2), arachidonate 5-lipoxygenase(ALOX5), vascular cell adhesion molecule 1(VCAM1), nitric oxide synthase 2(NOS2), prostaglandin E2 receptor EP2 subtype(PTGER2), gamma-aminobutyric acid receptor subunit alpha(GABRA), gamma-aminobutyric acid type B receptor subunit 1(GABBR1), and 4-aminobutyrate aminotransferase(ABAT). This study reveals the effective components and mechanism of QKL Oral Prescription.

Bioinformatics and expression analysis on MYB-related family in Angelica dahurica var. formosana / 中国中药杂志

In recent years, the MYB-related gene family has been found pivotal in plant growth and development. MYB-related gene family in Angelica dahurica var. formosana was systematically investigated based on "Chuanzhi No. 2" through transcriptome database search and bioinformatics and the temporal and spatial expression patterns were analyzed through real-time fluorescence-based quantitative polymerase chain reaction(PCR). The results showed that 122 MYB-related proteins family were identified, mainly including the unstable hydrophilic proteins with good thermal stability. Most of the proteins were located in nuclei. The majority of the proteins had the structures of random coil and α-helix. Five MYB-related proteins family of A. dahurica var. formosana had membrane-binding domains. The conserved domain analysis of MYB-related proteins family of A. dahurica var. formosana showed that the MYB domains of genes in five subgroups, similar to 2 R-, 3 R-, and 4 R-MYB proteins, contained three evenly distributed Trp(W) residues in the MYB repeat sequence. The phylogenetic analysis of MYB-related proteins family in A. dahurica var. formosana and Arabidopsis thaliana showed that the MYB-related members were unevenly distributed in five subgroups, and A. thaliana and A. dahurica var. formosana had almost the same number of genes in the CCA1-like subgroup. There were differences in the number, type, and distribution of motifs contained in 122 encoded proteins. Transcription factors with similar branches had similar domains and motifs. The expression pattern analysis showed that the transcription factors AdMYB53, AdMYB83, and AdMYB89 responded to hormones to varying degrees, and they were highly expressed in leaves and responded quickly in roots. This study lays a foundation for further investigating the function of MYB-related transcription factors of A. dahurica var. formosana and solving the corresponding biological problems such as bolting early.

Complex mechanisms of chronic pain in knee osteoarthritis identified by neuroimaging technology / 生理学报

Chronic pain of knee osteoarthritis (KOA) greatly affects the quality of life and functional activities of patients. It is important to clarify the underlying mechanisms of KOA pain and the analgesic effect of different therapies. Neuroimaging technology has been widely used in the basic and clinical research of pain. In the recent years, neuroimaging technology has played an important role in the basic and clinical research of KOA pain. Increasing evidence demonstrates that chronic pain in KOA includes both nociceptive and neuropathic pain. The neuropathic mechanism involved in KOA pain is complex, which may be caused by peripheral or central sensitization. In this paper, we review the regional changes of brain pathophysiology caused by KOA pain based on magnetic resonance imaging (MRI), electroencephalogram (EEG), magnetoencephalogram (MEG), near-infrared spectroscopy (NIRS) and other neuroimaging techniques. We also discuss the central analgesic mechanism of different KOA therapies, with a focus on the latest achievements in the evaluation and prediction of pain. We hope to provide new thoughts for the treatment of KOA pain, especially in the early and middle stages of KOA.

Bioinformatics analysis and expression pattern of NAC transcription factor family of Angelica dahurica var. formosana from Sichuan province / 中国中药杂志

NAC(NAM/ATAF/CUC) protein plays an important role in plant growth and development, secondary cell wall formation and stress response. In this study, based on the sequencing data of Angelica dahurica, the NAC family was systematically analyzed using bioinformatics methods and its expression pattern was analyzed. Studies showed that 75 candidate genes had been selected from the NAC transcription factor family of A. dahurica, with the protein size of 148-641, all of which were unstable hydrophilic proteins. Most NAC proteins were localized in the nucleus, and had complete NAC domain. Phylogenetic analysis of NAC family proteins of A.dahurica and Arabidopsis thaliana showed that among the 17 subfamilies, NAC members were unevenly distributed in each subfamily, indicating that the evolution of species is developing in multiple directions. Among them, ANAC063 subfamily contained no NAC sequence of A. dahurica, which might be due to the functional evolution of the species. Analysis of protein transmembrane structure and signal peptide showed that NAC transcription factor could carry out transmembrane transportation, but its signal peptide function had not been found. Expression analysis showed that most transcription factors responded to abiotic stress and hormones to varying degrees, and the effects of hormones were obvious, especially ABA and IAA. In different organs of A. dahurica, most members of the NAC family had higher expression in root phloem, followed by root xylem. This study lays a foundation for further research on the function of A. dahurica NAC transcription factor and for solving the biological problems of A. dahurica.

Early intervention with Di-Dang Decoction prevents macrovascular fibrosis in diabetic rats by regulating the TGF-β1/Smad signalling pathway / 中国天然药物

Macroangiopathy is a complication of Type II Diabetes Mellitus (T2DM), which is mainly caused by fibrosis of blood vessels. Using T2DM rat models, we investigated whether the traditional Chinese medicine, Di-Dang Decoction (DDD), exhibited anti-fibrotic actions on great vessels. T2DM rats were randomly divided into non-intervention group, early-, middle-, late-stage DDD intervention groups and control groups, including pioglitazone group and aminoguanidine group. After administration of DDD to T2DM rats at different times, we detected the amount of extracellular matrix (ECM) deposition in the thoracic aorta. The results showed that early-stage intervention with DDD could effectively protect great vessels from ECM deposition. Considering that TGF-β1 is the master regulator of fibrosis, we further validated at the molecular level that, compared to middle- and late-stage intervention with DDD, early-stage intervention with DDD could significantly decrease the expression levels of factors related to the activated TGF-β1/Smad signalling pathway, as well as the expression levels of downstream effectors including CTGF, MMP and TIMP family proteins, which were directly involved in ECM remodelling. Therefore, early-stage intervention with DDD can reduce macrovascular fibrosis and prevent diabetic macroangiopathy.

Advances in the treatment of acute closed Achilles tendon rupture / 中华骨科杂志

Acute closed Achilles tendon rupture is a common sport injury.Rupture of the Achilles tendon may limit the ability of physical exercises and activities of daily life.Conservative treatment has long recovery time and high risk of re-rupture of Achilles tendon.In recent years,with the early functional rehabilitation exercise,including early weight bearing and ankle joint flexion and extension exercise under the protection of orthopaedic braces,re-rupture risk of Achilles tendon has been significantly reduced,thus conservative treatment is becoming more and more popular.The surgical treatment mainly includes traditional open surgery and minimally invasive surgery.Minimally invasive treatment has less trauma,low re-rupture rate like open surgery,low risk of wound infection and is helpful for early rehabilitation.However,the risk of the sural nerve injury is higher.Open surgery has clear operating field and low re-rupture rate and low risk of the sural nerve injury.However,it still has some problems such as superficial and deep infection of the incision,suture reaction,tissue adhesion and so on.Both of them can achieve satisfactory results in the treatment of acute closed Achilles tendon rupture.Although the mechanism of injury of acute closed rupture of the Achilles tendon and epidemic characteristics have a deeper understanding,including degenerative tendon rupture and mechanical rupture of Achilles tendon,the incidence rate showed a rising trend,and affected by the geographical,gender,age and other factors,due to the existence of a variety of patient groups,there is still controversy over the optimal treatment modalities resulting from the diversity of the patient population.According to the individual differences of different groups of patients,the combination of early rehabilitation exercise can achieve satisfactory clinical effects as long as the treatment methods are appropriate.At present,the effect of biological therapy on the healing of Achilles tendon and the prevention of deep vein thrombosis are still controversial.There is no definitive evidence for the effectiveness of biological therapy and the need for prophylactic anticoagulation.The purpose of this study is to summarize the treatment of acute closed Achilles tendon rupture,and to discuss the importance of early functional exercise for acute closed Achilles tendon rupture and its effect on prognosis.
