ABSTRACT
Objective To investigate the material basis and antitumor mechanism of Marsdenia tenacissima (MT) on hepatocellular carcinoma (HCC) by bioinformatics, network pharmacology and molecular docking technology. Methods Active ingredients of MT were collected by literature search and screened by Swiss ADME website, which targets were predicted by Swiss Target Prediction. The chip data of HCC (GSE147888) were downloaded from the NCBI Gene Expression Omnibus (GEO) database. Differentially expressed genes were screened by R software. HCC-related targets were collected from the Genecards and OMIM databases. The Venny online tool was used to obtain the intersection of the herbal medicine targets and the disease targets. Subsequently, drug-target network and protein–protein interaction (PPI) network were constructed by Cytoscape software and String platform. GO enrichment analysis and KEGG pathway analysis were performed to analysis the functions and pathways enriched by key genes. The expression of key genes in HCC and its effect on survival were analyzed by the GEPIA database. The Human Protein Atlas (HPA) was used to analyze the immunohistochemical expression of key genes in HCC. Finally, molecular docking was carried out to investigate interactions between the top five targets and their related active compounds. Results A total of 50 active components were screened and 12 common targets were identified related to MT and HCC. Scutellarein-4-Methylether, Tenasogenin, Sinapic Acid, Dresgenin and Kaempferol were considered as the critical components. JUN, MMP9 and PTGS2 were recognized as key therapeutic targets. The GO analyses demonstrated that key targets mainly involved in the process of gene silencing and inflammatory response. KEGG analysis suggested that key targets were enriched in TNF signaling pathway and IL-17 signaling pathway. Survival analysis by the GEPIA showed significant differences in the expression of ESR1, MMP1, MMP9, JUN, and PPARG between high and low risk groups. Immunohistochemical results showed that ESR1 and MMP9 were differentially expressed in normal and hepatocellular carcinoma tissues. The molecular docking results verified that the drug active ingredient could be stably bound to the target protein. Conclusion This study reflected the multi-component, multi-target and multi-pathway characteristics of the MT in the treatment of HCC, which could provide a scientific basis for the clinical application of MT in HCC.
ABSTRACT
Objective To understand the ability and level of emergency rescue at general hospitals in Tianjin city. Methods Such actions as formulating plans and examination forms, establishing assessment indicators and evaluation criteria, and simulation exercises were performed to evaluate the capacity of 28 general hospitals in terms of their organizational structure, emergency response, event reporting, and summary assessment. Results The emergency response assessment system consisted of 4 level-1 indicators, 19 level-2 indicators and 58 level-3 indicators. 28 hospitals were found high in their overall emergency response capacity, but some were found with setbacks. For example, the " organizational structure" scored the highest in 4 first-level indicators, up to 88. 91％ , while " incident report" scored the lowest, down to 67. 99％ . Among level-2 indicators, professional emergency professional procedures and initial reporting scored the lowest. Conclusions In order to further improve the ability of medical institutions to respond to emergency events, the hospitals are recommended to enhance their backup resources for emergency response, their staff′s awareness of first aid knowledge and first aid skills, as well as their timeliness of initial reports and the completeness of progress reports.
ABSTRACT
Objective To learn the current capacity building of emergency response teams in Tianjin for the purpose of goals setting.Methods Health Emergency Capacity Questionnaire was issued to 89 secondary and above medical institutions and 19 CDCs in Tianjin.The form covered such items as basic institutional information, workforce makeup, emergency preparations, detection and early warning, emergency response, and summary/assessment.Data collected in the questionnaire were subject to descriptive and correlation analysis.Results Tianjin has scored an initial success in emergency medicine as evidenced in its emergency response mechanisms in place, elevated capacity in emergency medical rescue and disposal, and enhanced competence of emergency teams.Rooms of improvement however include insufficient professionalism and independence of health emergency, inadequate emergency commanding and decision making system functions, insufficient laboratory test capacity at district/county levels, and insufficient social involvement in health emergency.Conclusions Top-down design should be emphasized, health emergency response should be enhanced in terms of management and response planning system, while capacity building of the teams and long-term primary care emergency mechanism deserve higher attention.
ABSTRACT
Objective To observe effect of cognitive level and self-care ability of protective motivation intervention based on the quantitative evaluation in elderly patients with osteoporosis. Methods A total of 116 cases patients with senile osteoporosis from May 2013 to April 2015 were divided into the observation group and the control group. The control group implemented routine care, the observation group was given protective motivation intervention based on quantification protection motivation assessment strategies. Then cognitive level, self-care ability, quality of life were compared between two groups. Results Disease related knowledge cognition level:osteoporosis risk factors, sports knowledge, calcium score in the observation group were significantly higher than those in the control group (t=8.428, 10.104, 6.775, P < 0.05). Self-care ability: self-care ability, self-care responsibility, self-care knowledge scores in the observation group were significantly higher than those in the control group(t=2.230-5.162, P<0.05). Life quality:physical function, role-physical, bodily pain, general health, vitality, social function, role-emotional, mental health ect scores in the observation group were significantly higher than those in the control group (t=6.804-10.488, P < 0.05). Conclusions Protective motivation intervention based on the quantitative evaluation is helpful to enhance the cognitive level of disease knowledge and improve the self-care ability, as well as improve the quality of life.
