Participants were divided into three groups based on different potassium-lowering regimens, viz, SZC group (40 patients), insulin with glucose (IG) group (38 patients) and SZC + IG group (48 patients). Changes in potassium levels, other serum electrolytes (magnesium, sodium, phosphate, calcium), alanine aminotransferase (ALT) and albumin before and after treatment were recorded. Adverse reactions during treatment were also recorded. Results: Post-treatment, the potassium levels in all three groups exhibited a significant reduction when compared to pre- treatment values (p < 0.05). The SZC + IG group showed the highest efficacy, with a significant reduction in blood potassium levels observed 4 h after administration, which was more pronounced compared to other groups. The SZC + IG group, maintained potassium ion concentration at a normal level for a longer duration and no serious adverse reactions were observed during treatment. Conclusion: Intervention with SZC + IG lowers blood potassium levels, maintains it within normal range, and is more effective than the individual use of SZC or IG. A combination of sodium zirconium cyclosilicate, insulin and glucose infusion for treating hyperkalemia will need to be investigated further in a large-scale multicenter study.","PeriodicalId":23347,"journal":{"name":"Tropical Journal of Pharmaceutical Research","volume":"90 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135685379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mice (n = 30) were assigned in equal numbers to 5 groups (n = 6). All injections were given via the tail vein. The miR-22 expressions in aortas of mice in each group were determined with quantitative reverse transcription-polymerase chain reaction (qRT-PCR).

There was significantly lower protein expression of MAPK-14 in mice aorta in miR-22 overexpression mice than in overexpression control mice, but significantly upregulated in miR-22 inhibition mice, relative to that in inhibition control mice (p < 0.05).

Treatment was discontinued for patients who met therapeutic criteria set by relevant Asian-Pacific regions. Polymerase chain reaction (PCR) was used to amplify the genome in P region of serum rcDNA before treatment, cccDNA during drug cessation period, and serum rcDNA at relapse.

RUS (1 or 10 μM) was used to treat MPP+ induced SH-SY5Y cells. Cell viability was assessed using CCK-8 assay. The concentrations of lactate dehydrogenase (LDH), superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT) and glutathione peroxidase (GPx) were determined by enzyme-linked immunosorbent assay (ELISA). ATP production, Ca2+ concentration and JC-1 were quantified using commercial kits. The expression levels of tyrosine hydroxylase (TH), Keap1, Nrf2 and HO-1 were evaluated by western blot analysis.Results: RUS protected cell viability, reduced LDH production, and elevated TH expression in MPP+- modified SH-SY5Y cells. RUS promoted the release of SOD, CAT and GPx, but suppressed MDA production. Furthermore, RUS enhanced ATP metabolism, decreased Ca2+ leakage and maintained mitochondrial function.
