ABSTRACT
Objective: To explore the mechanism of Ertong Huichun Granules in treatment of respiratory virus infection diseases by network pharmacology and molecular docking. Methods: TCMIP, TCMSP and BATMAN-TCM databases were used to search and summarize the meridian and components of medicinal materials from Ertong Huichun Granules. PubChem and Swiss Target Prediction database were used to query the targets corresponding to the active components, and the respiratory virus infection-related targets were inquired in the GeneCards database. The KEGG pathway and GO biological process enrichment were analyzed by DAVID database, and the relevant network was constructed by Cytoscape software. According to the analysis results of the network diagram, components and targets were selected for molecular docking. Results: The herbs in Ertong Huichun Granules were most attributed to lung, stomach, liver meridian; combining database and literature retrieval. A total of 126 Chinese native medicine ingredients and 55 targets were ensured for constructing network. KEGG pathways mainly included cancer, hepatitis related pathways, PI3K-Akt signaling pathway, TNF signaling pathway, and HIF-1 signaling pathway, which were mainly involved in inflammatory response, transmembrane receptor protein tyrosine kinase signaling pathway, hypoxia response, and other biological processes. Molecular docking results showed that 7,8-didehydrocimigenol, cimicifugoside, and cimigenol from Cimicifuga foetida had good binding capacity with PTGS2, MAPK, ACE2, and 3CL hydrolase (3CLpro), and maybe have potential anti-respiratory virus effects. Conclusion: Gallic acid, 7,8-didehydrocimigenoll, ccimicifugoside, baicalin, and other ingredients from Ertong Huichun Granules can be through PTGS2, EGFR, MAPK, IL2, ACE2, and 3CLpro targets for reducing inflammatory reaction, interference virus invasion of the host and inhibiting the virus replication to play the role of treating the respiratory virus infection diseases.
ABSTRACT
Parasitism is composed by three subsystems: the parasite, the host, and the environment. There are no organisms that cannot be parasitized. The relationship between a parasite and its host species most of the time do not result in damage or disease to the host. However, in a parasitic disease the presence of a given parasite is always necessary, at least in a given moment of the infection. Some parasite species that infect humans were inherited from pre-hominids, and were shared with other phylogenetically close host species, but other parasite species were acquired from the environment as humans evolved. Human migration spread inherited parasites throughout the globe. To recover and trace the origin and evolution of infectious diseases, paleoparasitology was created. Paleoparasitology is the study of parasites in ancient material, which provided new information on the evolution, paleoepidemiology, ecology and phylogenetics of infectious diseases.
O parasitismo é composto por três subsistemas: o parasito, o hospedeiro e meio ambiente. Não existe organismo que não possa ser parasitado. A relação entre um parasito e suas espécies de hospedeiro não resulta, na maior parte das vezes, em dano ou doença ao hospedeiro. Entretanto, numa doença parasitária, a presença de um determinado parasito é sempre necessária, pelo menos em um determinado momento da infecção. Algumas espécies de parasitos que infectam humanos foram herdados dos pré-hominídeos, e foram compartilhados com outras espécies de hospedeiro filogeneticamente próximas, mas outras espécies foram adquiridas pelo meio ambiente à medida que os humanos se desenvolveram. As migrações humanas espalharam os parasitos adquiridos por todo o mundo. Para recuperar e traçar a origem e evolução das doenças infecciosas foi criada a paleoparasitologia. Paleoparasitologia é o estudo dos parasitos em materiais antigos, que trouxe novas informações na evolução, paleoepidemiologia, ecologia e filogenética das doenças infecciosas.

En Cuba es de carácter obligatorio realizar al 100 por ciento de la sangre donada, pruebas de laboratorio para detectar anticuerpos contra los Virus de Inmunodeficiencia Humana 1 y 2 (VIH), antígeno de superficie del Virus de la Hepatitis B (VHB), anticuerpos contra el Virus de la Hepatitis C (VHC) y la detección indirecta de Treponema pallidum por pruebas serológicas (VDRL o RPR), como ha regulado la Organización Panamericana de la Salud y el Centro para el Control Estatal de Control de la Calidad de los Medicamentos. Se decriben los resultados de esta vigilancia activa en donantes de sangre de la provincia de Cienfuegos desde 1989 hasta el 2009. Se aprecia notable descenso en la detección de casos positivos para la hepatitis B y sífilis a través de los años, mientras que el VIH mantiene un comportamiento caracterizado por cifras muy bajas, incluyendo varios años con ningún caso reportado. Finalmente la hepatitis C muestra una marcada tendencia al incremento en su incidencia entre este grupo poblacional
In Cuba is binding make the detection of antibodies against the 1 and 2 Human Immunodeficiency Virus (HIV), Antigen of the Virus surface of Hepatitis B (HBV) and antibodies against the Virus of Hepatitis C (HCV) and the realization of VDRL, 100 por ciento of donated blood, as it has regulated the Pan American Health Organization and the Center for the State Control of the quality of the medicines Control. This article describes the results of this active surveillance in donor of the Cienfuegos province from 1989 until 2009. Shows remarkable decline in the detection of Hepatitis B and syphilis over the years, while the HIV remains a behavior characterized by very low figures, including several years with no reported case. Finally the Hepatitis C shows a marked tendency to the increase in its incidence
