OBJECTIVE: To explore the influence of negative emotion on the professional identity of nurses in Guangdong Province and the moderating role of social support during COVID-19 pandemic. METHODS: A convenience sampling method was used to select 436 nurses in Guangdong Province as study subjects. The Depression-Anxiety-Stress Scale, Nurse Professional Identity Scale and Perceived Social Support Scale were used to investigate the negative emotion, professional identity and social support of these nurses. RESULTS: The median, the 25 th and 75 th percentile scores of the negative emotion total scores of nurses was 10.0(3.0,17.8). The total scores of professional identity and social support were(106.6±16.9) and(56.9±13.2), respectively. The professional identity and social support were negatively correlated with negative emotion(P<0.01), while the professional identity was positively correlated with social support in these nurses(P<0.01). The negative emotion of nurses can negatively predict their professional identity, and social support plays a moderating role in it.CONCLUSION: The higher the degree of social support, the less negative emotional impact on professional identity of nurses during COVID-19 pandemic. Nurses should be given more social supports.

Objective To determine the epidemiological characteristics of infectious disease related public health bud-events in Shanghai and assess the effects of bud-event surveillance， so as to provide scientific evidence for improving the surveillance system. Methods Surveillance data of infectious disease related public health bud-events were collected from 16 districts of Shanghai from 2017 through 2020. Then the data were analyzed and compared with infectious disease related public health emergencies during the same period. Results A total of 6 376 infectious disease related public health bud-events were documented in Shanghai in 2017‒2020， which involved 29 792 cases. There were two seasonal peaks， April through June and November through December. Clustered events accounted for 38.85%， mainly caused by chickenpox （14.10%）， hand，foot and mouth disease （11.17%） and norovirus-associated infectious diarrhea （6.54%）. The 36.73% of the bud-events occurred in school settings， which involved 24 718 cases （accounting for 83.00% of all cases）. Median time duration between onset date of the first cases and report date of the events was 4 days， and median duration of the events was 14 days， demonstrating positive correlation. In addition， all the infectious disease related public health emergencies（

Metastasis accounts for 90% of breast cancer deaths, where the lethality could be attributed to the poor drug accumulation at the metastatic loci. The tolerance to chemotherapy induced by breast cancer stem cells (BCSCs) and their particular redox microenvironment further aggravate the therapeutic dilemma. To be specific, therapy-resistant BCSCs can differentiate into heterogeneous tumor cells constantly, and simultaneously dynamic maintenance of redox homeostasis promote tumor cells to retro-differentiate into stem-like state in response to cytotoxic chemotherapy. Herein, we develop a specifically-designed biomimic platform employing neutrophil membrane as shell to inherit a neutrophil-like tumor-targeting capability, and anchored chemotherapeutic and BCSCs-differentiating reagents with nitroimidazole (NI) to yield two hypoxia-responsive prodrugs, which could be encapsulated into a polymeric nitroimidazole core. The platform can actively target the lung metastasis sites of triple negative breast cancer (TNBC), and release the escorted drugs upon being triggered by the hypoxia microenvironment. During the responsiveness, the differentiating agent could promote transferring BCSCs into non-BCSCs, and simultaneously the nitroimidazole moieties conjugated on the polymer and prodrugs could modulate the tumor microenvironment by depleting nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) and amplifying intracellular oxidative stress to prevent tumor cells retro-differentiation into BCSCs. In combination, the BCSCs differentiation and tumor microenvironment modulation synergistically could enhance the chemotherapeutic cytotoxicity, and remarkably suppress tumor growth and lung metastasis. Hopefully, this work can provide a new insight in to comprehensively treat TNBC and lung metastasis using a versatile platform.
