We find that during the COVID-19 pandemic, different nations have adopted three different response strategies to contain the new coronavirus: strict control with unlimited resources, relentless contribution with limited resources, and rough rationality with limited resources. We discuss what marketing innovation strategies that enterprises may adopt to survive and grow their businesses during and after the pandemic. This study provides important strategic implications for national policymakers and enterprises on the use of response strategies and marketing innovation strategies in both short and long run.","PeriodicalId":370947,"journal":{"name":"Clinical Immunology and Immunotherapy","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126340875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most important features of the epidemic process that leads to the conclusion of an underlying fractal structure are analyzed, and the meaning of the parameters of the model are investigated.

It is shown that the contamination rate varies with the population size. The relevant differences between the SIR model and the fractal model are discussed.","PeriodicalId":370947,"journal":{"name":"Clinical Immunology and Immunotherapy","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130954647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The expression of ROR t mRNA and Foxp3mRNA in PBMC was detected by RT-PCR. OME rat model was established and the changes of lymphocytes in middle ear mucosa and spleen and PI3K/Akt/mTOR signaling in middle ear mucosa were detected by HE staining, IHC, WB and flow cytometry.Results: The immune imbalance of Treg/Th17 in secretory otitis media (OME) was confirmed by the expression of cytokines in OME serum and analysis of ROR T and Foxp3 mRNA which was Th17 and Treg specific transcription respectively. OME rat model further confirmed that Treg/Th17 imbalance could lead to OME as demonstrated by staining of MIDDLE ear mucosa and expression of ROR T and Foxp3. PI3K, Akt, and mTOR proteins were expressed in the MIDDLE ear mucosa of OME group and CON group, respectively. Compared with CON group, the expression of P-MTOR and P-PI3K proteins in the middle ear mucosa of OME group was significantly increased.Conclusions: Treg/Th17 imbalances are found in OME patients and OME animal model and the pathogenic mechanism may be due to systemic abnormal immune response, activated PI3K/Akt/mTOR signaling, abnormal T cell differentiation, leading to middle ear mucosal hyperemia, edema and subsequent occurrence of OME.","PeriodicalId":370947,"journal":{"name":"Clinical Immunology and Immunotherapy","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134111609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As we have learned more about the virus, more targeted drugs have been prescribed. The inflammation phase is perhaps the most worrisome. It requires therapies that slow down the immune system activation [1]. Corticosteroids are the favorite drug. However, dosages and maintenance regime are still uncertain. We have already started to have some results on its effectiveness [2], which were not available at the beginning. We have used a three-day regimen of 125 or 250 mg methylprednisolone pulses according to clinical-analytical severity in our hospital. However, corticosteroids are not without risks. One of the most frequent risks is the reactivation of infections. Reactivation of the hepatitis B virus is especially important because it is frequent and we can prevent it. In addition, a recent study has linked chronic HBV infection with a decreased clearance rate of SARS-CoV-2 [3]. Therefore, we review the recommendations on the prophylaxis of reactivation of HBV infection in patients receiving corticosteroid pulses.","PeriodicalId":370947,"journal":{"name":"Clinical Immunology and Immunotherapy","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122328432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
