Evaluation of interaction of chlorogenic acid and cefotaxime sodium based on sequential analysis / 药学学报

The joint application of traditional Chinese medicine injection containing chlorogenic acid (CA) and cefotaxime sodium (CS) is sometimes appeared in clinical practice, but the scientific basis of drug molecular compatibility is still weak. This study proposes a sequential analysis strategy based on isothermal titration calorimetry (ITC), cold-spray ionization mass spectrometry (CSI-MS) and antibacterial activity test to evaluate the molecular interactions between CA and CS. The results of ITC experiments showed that the Gibbs free energy ΔG < 0 and it was driven by enthalpy change when CA titrated CS, suggesting CA could spontaneously chemically react with CS. Subsequently, the parent ions (m/z 808.143 5) of binding molecular of CA and CS was detected by CSI-MS, indicating CA could chemically bond with CS. Furtherly, the antibacterial experiments found the antibacterial ability of CS against Klebsiella pneumonia was significantly reduced (P < 0.01) by CA in mixed solution. Finally, molecular docking technology showed CA and CS have a common target of penicillin binding protein 3 (PBP3), suggesting that the phenomenon of CA reduced the antibacterial ability of CS may be related to the competitive binding of two components with PBP3. Our studies have shown that CA could spontaneously chemically bond to CS and reduced its antibacterial ability, providing scientific data for molecular interaction evaluation of CA and CS.

Brief discussion on the characteristics of meridian sinew theory at the early era / 中国针灸

The characteristics of meridian sinew theory at the early era have been collected. It is believed that the running courses and indications of twelve meridian sinew regions in Lingshu (Miraculous Pivot) are closely associated with Zubi Shiyimai Jiujing (Moxibustion Therapy on the Eleven Meridians of Legs and Arms) and Yinyang Shiyimai Jiujing (Moxibustion Therapy on the Eleven Meridians of Yin and Yang). Due to the attachment of twelve regular meridians, the development of its own theory is blocked. Meridian sinew theory guides the diagnosis and treatment of many dominant disorders (e.g. pain disorder and bi syndrome) with acupuncture and moxibustion. The defensive qi is circulated among meridian sinews, which is the core of meridian sinew theory. The acupoint selection relies on the meridian sinew theory at the early era, such as "consolidating muscles when they involved in disorders, using painful sites as acupoints to treat diseases" "interaction of the associated muscles" and "conducting meridian qi along with the running courses of meridians". The crack needling (one of the nine needling techniques exerted between two muscles to treat muscular pain) is adopted generally to mobilize the defensive qi so as to resist pathogens, relieve the compression in foci and promote qi and blood circulation in meridians. The rational understanding of meridian sinew theory may improve the accuracy of diagnosis and treatment of meridian sinew disorders, "reduce the pressure" on meridian theory and contribute to the enrichment of the theoretical framework of acupuncture and moxibustion.

Experimental Research Progress of Replenishing Qi and Activating Blood Circulation Traditional Chinese Medicine on Mitochondrial Quality Control in Treatment of Chronic Heart Failure / 中国实验方剂学杂志

Heart failure is a complex clinical syndrome，which is the final result of compensatory failure of heart injury caused by various reasons. Long-term persistent cardiac stress leads to mitochondrial dysfunction，which in turn further damages cardiomyocytes and leads to disease progression. Timely removal of damaged mitochondria in cardiomyocytes and maintaining a good living environment of viable mitochondria is not only an effective means to protect cardiomyocytes，but also a new way to prevent and treat heart failure and ventricular remodeling. Mitochondrial quality control is a series of cellular activities for mitochondria to maintain their structural and functional stability，including oxidative stress response，regulation of mitochondrial dynamics，mitochondrial autophagy，intracellular calcium regulation and so on. Traditional Chinese medicine（TCM） mostly uses drugs of replenishing Qi and activating blood circulation in the treatment of chronic heart failure，and Qi and mitochondria are similar in function. According to TCM，the performance of the body as "static，descending and inhibitory" in the case of Qi deficiency can also be compared with the energy defect of mitochondria. The classical method of tonifying qi and activating blood circulation in TCM can be applied here. In recent years，TCM takes mitochondria as the target and carries out many related experimental studies from the point of view of myocardial energy supply. It is found that Chinese herbs for replenishing Qi and activating blood circulation can participate in regulating the quality control mechanism of intracellular mitochondria with multiple targets and links. It is proved by experiments that Chinese herbs for replenishing Qi and activating blood circulation can exert myocardial protective effect through this mechanism.

Study on liver diseases with zebrafish as an important tool / 中国中药杂志

With the increasing incidence of hepatobiliary diseases, it is particularly important to understand the role of molecular, cellular and physiological factors in the clinical diagnosis and treatment with traditional Chinese medicine(TCM) in the development of liver disease. Appropriate animal models can help us identify the possible mechanisms of relevant diseases. Danio rerio(zebrafish) model was traditionally used to study embryonic development, and has been gradually used in screening and evaluation of liver diseases and relevant drug in recent years. Zebrafish embryos develop rapidly and the digestive organs of 5-day-old juvenile fish are all mature. At this stage, they may develop hepatobiliary diseases induced by developmental defects or compounds. Zebrafish liver is similar to human liver in cell composition, function, signal transduction, response to injury and cell process mediating liver disease. Furthermore, due to the high conservation of genes and proteins between humans and zebrafish, zebrafish becomes an alternative system for studying basic mechanisms of liver disease. Therefore, genetic screening could be performed to identify new genes involving specific disease processes, and chemical screening could be made for drugs in specific processes. This paper briefly introduced the experimental properties of zebrafish as model system, emphasized the study progress of zebrafish models for pathological mechanism of liver diseases, especially fatty liver, and drug screening and evaluation, so as to provide ideas and techniques for the future liver toxicity assessment of TCM.

Regulatory Mechanism of Traditional Chinese Medicine in Promoting Angiogenesis After Cerebral Infarction Based on STAT3/miRNA Feedback Loop / 中国实验方剂学杂志

Cerebral infarction is a clinical disease with corresponding neurological symptoms caused by cerebral ischemia and hypoxia caused by cerebral blood supply disorder. It is one of the most common cerebrovascular diseases and a serious threat to human health. The prevention and treatment of cerebral infarction has an important social significance. Angiogenesis is the key starting point for medical treatment of cerebral infarction, and signal transduction and transcriptional activators (STAT)/hypoxia inducing factor-1(HIF-1)/vascular endothelial growth factor (VEGF) pathway are important pathways to mediate angiogenesis after cerebral infarction. This paper took the angiogenesis as the starting point and the upstream molecules of STAT/HIF-1/VEGF signal pathway STAT3 and miRNA as the main study objects, and comprehensively discussed the results of chip sequencing, experimental research, traditional Chinese medicine (TCM) pathogenesis and TCM treatment. Based on the regulatory mode of "TF-miRNA" and the idea of "micro-whole", it is suggested that under the guidance of the basic theory of TCM, cubic compound prescriptions of TCM and its active components might activate the STAT/HIF-1/VEGF signal pathway through STAT3/miRNA feedback loop to promote angiogenesis after cerebral infarction, which puts forward a deep molecular mechanism and new direction for the treatment of cerebral infarction with TCM.

Study on regulation mechanism of Toutongning capsule through TNF signaling pathway in treatment of migraine based on systems pharmacology method / 中国中药杂志

Toutongning capsule (TTNC) is a traditional Chinese medicine(TCM) with good effect for treating migraine in clinical application. In this paper, a systems pharmacology method was carried out to study the TNF mechanism of the TTNC on the migraine. First, the ingredients for TTNC were collected from TCM databases, and ADME properties prediction was firstly applied to screen out the active compounds of TTNC. Then, the target searching and identification was performed by using CSDT model, and the targets were mapped to the migraine disease to determine the active targets through some common databases like TTD. To obtain the targets related with TNF signaling pathway, KEGG pathway analysis was performed by DAVID online analysis tool. Finally, the "herbs-compounds-targets" network was built by Cytoscape software. According to the results of degree and betweenness in the network, the key active compounds and targets were determined to explore the TNF mechanism for TTNC. Results showed that 19 active compounds and 8 targets played a crucial role in the treatment of migraine by TNF pathway for TTNC. This work provided a new perspective to deepen the understanding of the TNF signaling pathway mechanism in migraine treatment by TTNC, and may provide a necessary theoretical basis for the determination of effective markers and the clinical research of this medicine.

Study on active ingredient and mechanism in preventing vascular dementia of Tianzhusan coming from Tujia medicine / 中国中药杂志

To make clear of the absorbed components of Tianzhusan (TZS) and its possible mechanism in preventing vascular dementia (VD), the rats' models of VD were prepared by a permanent ligation of the bilateral common carotid arteries. After 60 days, rats were administrated with TZS for 0.1 g x kg(-1), and the volume is 0.02 mL x g(-1). After 3 days, the medicated serum was prepared and detected by UPLC, and then we predicted the possible chemical structure of the absorbed components of TZS. According to the absorbed components, the potential targets of TZS were found by ligand profiling of Discovery Studio 3.5. All of these target genes were submitted to DAVID onine for gene set enrichment analysis (GSEA). The 5 absorbed components of TZS have been predicted, and four of them have been identified as parishin B, parishin C, parishin, pennogenin-3-O-alpha-L-rhamnopyranosy-(1-->2)-beta-D-glucoside. Through reverse finding targets, we got 861 pharmacophore models and 9 pathways from KEGG, BIOCARTA after document verification. These results showed that the efficacy mechanism of TZS on VD perhaps were be related with these absorbed components and pathways. If the traditional herbs could be proved effective by efficacy tests, the serum pharmacochemistry, computer-aided drug design, system biology and other technologies can be used in the next experiments, which will be beneficial to fast discovery of material basis and mechanisms of traditional medicine coming form ethnic minorities.
