Background: Henoch-Schonlein purpura (HSP) is a common capillary allergic bleeding disease. To explore the variation of pyroptosis-related inflammatory factors level in the peripheral blood of patients with HSP.Methods: A total of 87 HSP patients treated in our hospital from June 2020 to March 2021 were selected and divided into the renal impairment group (n=29) and the non-renal impairment group (n=58) according to the presence of hematuria and proteinuria. A total of 50 healthy individuals from the hospital were selected as the control group. The renal impairment and non-renal impairment groups were treated with a regular regimen of compound glycyrrhizin tablets and glucocorticoids, respectively. Serum interleukin (IL)-18, IL-1β, and peripheral caspase-1-positive cells were compared pre-and post-treatment among the three groups.Results: The pre-treatment serum IL-1β levels in the renal impairment and non-renal impairment groups were significantly higher than that in the control group (P<0.01). After treatment, the IL-1β level in the nonrenal impairment group was not significantly different from that in the control group (P>0.05). However, the IL-1β level in the renal impairment group post-treatment was significantly higher than that in the other two groups (P<0.01). The positive rate of caspase-1 expression in peripheral blood before treatment in the renal impairment group and non-renal impairment group was significantly higher than that in the control group (P<0.01). After treatment, the positive rate of caspase-1 expression in the non-renal impairment group was comparable to that in the control group (P>0.05), whereas the rate in the renal impairment group was significantly higher than that in the other two groups (P<0.01). After treatment, the serum IL-1β levels and caspase-1 positive rate in HSP patients who were responsive to treatment (as assessed by hematuria or proteinuria levels after treatment) were lower than that in patients who were unresponsive to treatment P<0.001), but not significantly different to the control group (P>0.05).
Conclusions:The levels of serum IL-1β and caspase-1 changed in response to alterations in the disease condition and treatment response in HSP patients, which suggested that pyroptosis-related inflammatory factors may have potential application value in predicting disease progression and efficacy of hormone therapy.
The polyamidoamine (PAMAM) dendrimer, a type of macromolecule material, has been used in spheroidal cell culture and drug delivery in recent years. However, PAMAM is not involved in the study of hepatic cell-spheroid culture or its biological activity, particularly in detoxification function. Here, we constructed a PAMAM-dendrimer conjugate decorated by an integrin ligand: arginine–glycine–aspartic acid (RGD) peptide. Our studies demonstrate that RGD–polyethylene glycol (PEG)–PAMAM conjugates can promote singly floating hepatic cells to aggregate together in a sphere-like growth with a weak reactive oxygen species. Moreover, RGD-PEG-PAMAM conjugates can activate the AKT–MAPK pathway in hepatic cells to promote cell proliferation and improve basic function and ammonia metabolism. Together, our data support the hepatocyte sphere treated by RGD-PEG-PAMAM conjugates as a potential source of hepatic cells for a biological artificial liver system.
In order to explore the quality management efficiency of applying big data and artificial intelligence in nursing quality index, a method of building a nursing management platform integrating nursing indicators and nursing events is proposed. Based on the investigation of the application demand of nursing information system, the method achieves timely data sharing and transmission through WLAN technology and realizes nursing management monitoring, nursing quality index enquiry, and automatic statistical analysis under the vertical management mode of nursing. The results showed that 77 people (73%) thought the time decreased, 19 people (18%) thought the time was the same, and 9 people (7%) thought the time increased. In terms of intelligent application and big data of nursing information management system, there is a significant difference in nursing management efficiency before and after using nursing management information system (P < 0.001). The nursing management control platform is designed and applied, and the nursing quality control method and actual management process are improved, which is very good for strengthening nursing quality management. The overall optimization of the quality control process is realized, which helps to mobilize the initiative and enthusiasm of nursing staff and continuously improve the effectiveness of nursing management and nursing efficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
