ABSTRACT
Ophiopogonis Radix is an important Yin-nourishing drug in traditional Chinese medicine(TCM), with the effects of nourishing Yin, promoting fluid production, clearing away heart-fire, and relieving restlessness. It is widely used in clinical practice due to its multiple chemical components and pharmacological effects. The technique "mapping knowledge domains" is an effective tool to quantitatively and objectively visualize the development frontiers and trends of certain disciplines. In this study, TCM research papers related to Ophiopogonis Radix were retrieved from Web of Science(WoS) and CNKI, and the research institutions, journals, and keywords involved were visualized and analyzed using the scientometric software CiteSpace. The co-occurrence network of related research on Ophiopogonis Radix was constructed, and the Ophiopogonis Radix-disease-target network was plotted using Cytoscape 3.8.2. The hot topics in Chinese and English papers were analyzed and the shortcomings in the research on Ophiopogonis Radix were summed up. Furthermore, the development trends were discussed. A total of 1 403 Chinese papers and 292 English papers were included in this study. The analysis of research institutions showed that Beijing University of Chinese Medicine and China Pharmaceutical University were the two research institutions with the largest numbers of papers published. The analysis of journals showed that Hebei Journal of Traditional Chinese Medicine and Journal of Asian Natural Products Research were the two journals with the highest numbers of papers concerning Ophiopogonis Radix. The keyword analysis showed that the research contents of Chinese papers focused on the analysis of medication regularity and clinical observation trials, while the English papers focused on component analysis and pharmacological investigation. Data mining and apoptosis-based pharmacological mechanism might be the research trends in the future.

The disease-gene-drug multi-level network constructed by network pharmacology can predict drug targets and has been widely used in the study of material basis and mechanism of action of Chinese medicinal prescriptions. However, most of the current studies have normalized the efficacies of Chinese herbal medicines in the compounds during the construction of the network. There is also a lack of in-depth exploration of the mechanism of synergy among multiple components. This study proposed a network module partition method based on group collaboration and the pharmacological network was weighed according to the traditional Chinese medicine(TCM) theory of "monarch, minister, assistant and guide". Taking the Tanyu Tongzhi Prescription as an example, we constructed its pharmacological network for the treatment of myocardial ischemia-reperfusion injury. The group collaboration module in the network was identified and the network changes before and after the weighting were compared based on the network topology analysis to explore a new method to find the core nodes of the network as well as the core drugs that affected the efficacy of the compounds. The results showed that the module partition method based on group collaboration could be used to identify and partition group collaboration mo-dules in pharmacological networks of compounds. The proposed weighted network based on the TCM theory of "monarch, minister, assistant, and guide" could identify and partition the modules based on the characteristics of the pharmacological network. The identification and partition results of modules of Tanyu Tongzhi Prescription in the weighted network were superior to those in the unweighted network. The weighted closeness centrality(WCC) evaluation method was conducive to finding key nodes and relations in the network as compared with traditional methods, thereby providing a basis for analyzing the core components of drugs and extracting more accurate drug components and targets.

Objective:To predict the potential molecular mechanism of Yangxue Antai Fang in treating prethrombolic state of recurrent spontaneous abortion （RSA-PTS）. Method:The chemical constituents and drug targets of Yangxue Antai Fang were collected by Integrated Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP V2.0）. RSA-PTS disease target information was collected by TCMIP V2.0 and improved by Online Mendelian Inheritance in Man （OMIM） database. The interaction of these targets was analyzed and key target network was constructed. Gene ontology （GO） function and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis were further performed. Finally， Cytoscape 3.5.1 was used to build up a multidimensional network of TCM-ingredient-target-pathway. The levels of absorption， distribution， metabolism， excretion and toxicity （ADMET） of the main components in the network were analyzed. Result:A total of 310 chemical constituents and 975 targets were collected from 8 TCMs in Yangxue Antai Fang. A total of 143 targets of RSA-PTS were obtained. A total of 243 core targets were obtained by the interrelationship analysis of drug and disease targets. The analysis of the top 100 core targets showed that these targets might participate in treating RSA-PTS by affecting biological processes related to thrombosis， such as blood coagulation， platelet activation， positive regulation of angiogenesis and so on. Pathway analysis showed that these targets were mainly concentrated in complement and coagulation cascades， platelet activation， estrogen signaling pathway， thyroid hormone signaling pathway， etc. Multidimensional network analysis in combination with ADMET level showed that 14 components （leonurine， paeonol， vanillin， and so on） may play a therapeutic role in RSA-PTS by affecting coagulation factors Ⅱ （F2）， plasminogen （PLG） and estrogen receptor 1 （ESR1） proteins involved in complement and coagulation cascades， platelet activation， thyroid hormone signaling pathway and others. Conclusion:The main chemical constituents in Yangxue Antai Fang may improve RSA-PTS by regulating complement and coagulation cascades， blood coagulation， platelet activation and other biological processes.
ABSTRACT
@#ObjectiveTo explore the correlation between psychologic status and personality characteristics of certain recruits.Methods168 recruits were surveyed by Symptom Checklist 90 (SCL-90) and Eysenck Personality Questionnaire (EPQ).ResultsIn 168 recruits, the factorial scores including interpersonal sensitivity, hostility and phobia were higher than the norm of Chinese and PLA (P<0.05～0.01). In junior high school recruits, the factorial scores including hostility and constrain were higher than the senior school recruits (P<0.05). Certain recruits showed higher scores of factor P, factor N, and lower scores of thinking factor, factor E and factor L and all the factors of SCL-90 compared with the norm of Chinese.ConclusionThe mental status and personality characteristics of certain recruits are poor. The company should strengthen psychological education and quickly adapt the recruits to the military circumstance.
