Objective To systematically evaluate the rumination in stroke patients and identify the influencing factors.Methods A mixed-methods systematic review was carried out by searching databases,such as CNKI,WanFang Data,VIP,CBM,PubMed,Web of Science,the Cochrane Library,Embase and Scopus databases,from the inception to 27th October,2023,for literature on the influencing factors of rumination in stroke patients.The researchers evaluated quality of the literature according to the mixed methods appraisal tool developed by McGill University of Canada.Then the data were collected,analysed and integrated using the convergent integration method proposed by the JBI Evidence-Based Health Care Research Centre of Australia.Results A total of 22 studies were included with an involvement of 4 949 patients.Then a total of 45 research topics were extracted and grouped into 8 categories.The influence factors of rumination were integrated,including individual factors,external support and coping strategies.Conclusions Stroke patients have different levels of rumination.Individual factors may affect rumination in patients.Harmonious interpersonal relationships and positive thinking with coping strategies can promote deliberate rumination.However,the effects of age,place of residence and household income on rumination in stroke patients are required to be further explored.

Background: Acute respiratory distress syndrome induced by acute lung injury (ALI) is the main cause for the high mortality of corona-virus disease 2019 (COVID-19). Huashi Baidu formula (HSBD) with the effects of eliminating dampness, clearing heat, ventilating lung, and removing toxin has been proven to be effective in the treatment of COVID-19, especially in severe cases. However, the underlying mechanism and target proteins of HSBD remain unclear. Objective: To provide evidence and decipher the mechanism of HSBD in alleviating inflammation and ALI. Materials and methods: A mouse model of ALI was induced by lipopolysaccharide (LPS), and hematoxylin-eosin staining was used to examine the protective effects of HSBD on the model mice. The cellular thermal shift assay and proteomics analysis were used to predict the target proteins. Furthermore, the A549 cells with peroxiredoxin 5 (PRDX5) knockdown were established to validate the predicted proteins. Results: Huashi Baidu formula treatment mitigated ALI and inflammatory cytokine dysfunction in LPS-induced mice, thus exerting a therapeutic effect on COVID-19. Huashi Baidu formula could serve as a therapeutic agent to alleviate inflammation and lung injury via nuclear factor k B and phosphatidylinositol 3-kinase signaling and interleukin 17 inhibition as well as targeting PRDX5, which could be one of the promising targets for treating inflammation. In the A549 cell line with PRDX5 knockdown (si-PRDX5), the anti-inflammation effects of HSBD, including reversing LPS-induced increase in the nitric oxide level and reduction in the hydrogen peroxide content, were attenuated. Thus, HSBD protected A549 cells from LPS-induced inflammation mainly by targeting PRDX5. Conclusions: Huashi Baidu formula alleviates ALI by targeting nuclear factor κB/phosphatidylinositol 3-kinase and PRDX5, as well as inhibiting the immune response induced by IL-17.
