RESUMEN
Objective:To study the main active components and potential mechanism of the treatment of ovarian cancer by Scutellariae Barbatae Herba - Cremastrae Pseudobulbus Pleiones Pseudobulbus based on network pharmacology and in vitro cell experiments.Methods:TCMSP and SwissTargetPrediction databases were used to retrieve and collect the active components and targets of Scutellariae Barbatae Herba - Cremastrae Pseudobulbus Pleiones Pseudobulbus, and four databases including GeneCards, OMIM, DrugBank and DisGeNET were used to search the targets related to ovarian cancer. After screening the common potential targets of Scutellariae Barbatae Herba - Cremastrae Pseudobulbus Pleiones Pseudobulbus and ovarian cancer, the STRING database was used to realize the construction of PPI network interacting with the proteins of the two common targets. DAVID database was used for GO and KEGG enrichment analysis. Cytoscape 3.9.0 software was used to construct the "active component-target-pathway" network. Finally, the key targets and pathways were validated in vitro. MTT method was used to detect the proliferation inhibition rate of human ovarian cancer SKOV3 cells with different concentrations of Quercetin and sitosterol. Human ovarian cancer SKOV3 cells were divided into control group, Quercetin group and sitosterol group according to the random number table method. After corresponding drug intervention for 48 hours, the effects of Quercetin and sitosterol on SKOV3 cell cloning ability were detected by clone formation experiment, the levels of Akt1, VEGFA, Caspase-3 mRNA in each group were detected by PCR, and the protein expressions of PI3K, Akt, p-Akt, Caspase-3, and VEGFA in cells were detected by Western blot.Results:Through screening, 29 effective chemical components in Scutellariae Barbatae Herba and 3 effective chemical components in Cremastrae Pseudobulbus Pleiones Pseudobulbus were obtained, including 2 components in total. 291 drug-related targets, 1969 potential targets of ovarian cancer were acquired. There were 137 common targets of "Scutellariae Barbatae Herba - Cremastrae Pseudobulbus Pleiones Pseudobulbus" and the drug-disease intersection of ovarian cancer. Through GO functional analysis, 930 items were obtained, involving 722 biological processes, 76 cellular components and 132 molecular functions. KEGG enrichment analysis involved 169 signaling pathways, including tumor pathway, PI3K-Akt signaling pathway, P-53 signaling pathway, IL-17 signaling pathway, etc. In vitro experiment results showed that cell proliferation inhibition rate increased and cell cloning ability decreased in Quercetin and sitosterol groups; The levels of Akt1 and VEGFA mRNA in Quercetin group and sitosterol group decreased ( P<0.01 or P<0.05), the expression of Caspase-3 mRNA and protein increased ( P<0.01), and the expressions of PI3K, p-Akt and VEGFA protein decreased ( P<0.01). Conclusion:Scutellariae Barbatae Herba - Cremastrae Pseudobulbus Pleiones Pseudobulbus inhibits the occurrence and development of ovarian cancer through multi target and multi pathway synergistic effects, and can induce SKOV3 cell apoptosis by regulating the expressions of key genes such as AKT1, VEGFA, Caspase-3, and PI3K/Akt pathway.
RESUMEN
INTRODUCTION@#The purpose of this study was to assess the application of the early warning score system (EWS-S) and gauge physician awareness, perceptions of necessity and attitudes regarding these tools based on previously experienced unnoticed clinical deterioration (CDET).@*METHODS@#A cross-sectional survey was carried out via an online questionnaire at a large 3,500-bed Class 3A general hospital in China. A total of 299 physicians of adult general wards were asked to answer a translated questionnaire that was localised from the original version. Demographic profiles of patients were included as well as three other sections assessing awareness of CDET/EWS-S and gauging attitudes towards and perceptions of the necessity of EWS-S at our hospital.@*RESULTS@#A high level of physician awareness of the CDET problem was observed. Most physicians knew about the existence of a systematic assessment tool for clinical application. Physicians with previous experience in reanimation, unplanned transfer to intensive care unit (UTICU) and/or death tended to consider EWS-S necessary in attentive and well-trained staff (p < 0.05). Physicians who had previous experience with UTICU were more likely to recommend implementing EWS-S in their wards compared with those without such experience (p < 0.05).@*CONCLUSION@#Most physicians have positive attitudes towards EWS-S. However, their awareness should be further heightened. Physicians who had previous experience with CDET/UTICU were more likely to employ EWS-S in their clinical practices. To better facilitate the implementation of EWS-S in Chinese hospitals, existing facilities, policy supports, standardised managements and the development of information systems should be strengthened.

Objective:To control the pandemic of coronavirus disease 2019 (COVID-19) effectively, strict isolation measures have been taken in China. Suspected patients must be isolated, and the confirmed patients specifically are isolated in negative-pressure isolation rooms. During the isolation, patients face difficulty in adapting to their surrounding environment, worry about the prognosis of the disease, lack confidence in treatment, separate from their families, and have a sense of distance from medical staff. Isolated patients may possess the feelings of negativity, including loneliness, anxiety, depression, insomnia, and despair. Hence, to reduce the risk of adverse psychological outcomes,"family member-like"care strategies were developed and implemented to solve problems associated with the COVID-19 pandemic. This study aims to examine whether using"family member-like"care strategies can improve psychological resilience and reduce depression, anxiety, and stress symptoms among patients with COVID-19 in an isolation ward.Methods: A quasi-experimental design was used to evaluate the"family member-like"care strategies for adult patients with COVID-19 in an isolation ward. COVID-19 patients in the Xiangya ward of the West District of the Union Hospital of Tongji Medical College of Huazhong University of Science and Technology in Wuhan, Hubei province, were included in this study from February 9 to March 20, 2020. Healthcare providers who volunteered as family members were assigned to patients. They practiced one-to-one care and provided continuous and whole care for the patients who were from admission to discharge. Connor-Davidson Resilience Scale-10 (CD-RISC-10) and Depression Anxiety Stress Scale-21 (DASS-21) were used to evaluate the resilience and psychological status of COVID-19 inpatients upon hospital admission, 2 weeks after admission, and at their discharge from the hospital. Results: The questionnaire response rate of the"family member-like"strategies was 100％. Of the 60 patients, 39 (65.0％) were male, and 21 (35％) were female. The hospital stay was (27.5±3.5) days. All the 60 patients were cured and discharged without any death and serious complications. The total scores for CD-RISC were 8.83±6.86 at admission, 29.13±5.42 at 2 weeks after admission, and 33.87±6.14 at discharge, which were significantly improved at the 2 follow-ups (F=404.564, P<0.001). Multivariate analysis and repeated measurements also indicated that patients experienced significant improvements in tenacity (F=360.839, P<0.001), strength (F=368.217, P<0.001), and optimism (F=328.456, P<0.001) at the 2 follow-ups. The total scores of DASS-21 were 49.27±11.30 at admission, 30.77±16.71 at 2 weeks after admission, and 4.17±11.03 at discharge, and the scores were significantly decreased at the 2 follow-ups (F=270.536, P<0.001). Multivariate analysis and repeated measurements also indicated that patients experienced significant decreases in depression (F=211.938, P<0.001), anxiety (F=285.592, P<0.001), and stress (F=287.478, P<0.001) at the 2 follow-ups.Conclusion:"Family member-like"strategies had positive effects on improving psychological resilience and reducing the symptoms of anxiety and depression of COVID-19 patients. It might be an effective care method for COVID-19 patients. It should be incorporated into emergency care management to improve care quality during public health emergencies of infectious diseases.
