Objective To explore and study the correlation between interleukin-33(IL-33),interleukin-37(IL-37),leucine-enriched nucleotide-binding oligomeric domain(NLRP)- 3,the ratio of natural killer(NK)cells/dendritic cells(DC)and the conditions of patients with chronic hepatitis B(CHB). Methods From February 2020 to September 2022,86 patients with CHB treated in our hospital were selected as hepatitis group,and 86 healthy patients were selected as control group during the same period. The contents of IL-37,IL-33 and NLRP3 in serum of the two groups were detected,and NK/DC ratio was calculated. Serum alanine aminotransferase(ALT),aspartate aminotransferase(AST)and total bilirubin(TBIL)of all the selected subjects were detected and correlation analysis was carried out. Results Compared with the control group,the serum ALT,TBIL and AST in hepatitis group were significantly increased(P<0. 05),the contents of IL-33,IL-37 and NLRP3 were higher(P<0. 05),and the NK/DC ratio was significantly decreased(P<0. 05). In the hepatitis group,Pearson analysis showed that IL-33,IL-37,NLRP3 and NK/DC ratios were correlated with ALT,TBIL and AST(P<0. 05). In the hepatitis group,ROC curve analysis showed that the maximum areas under the curve of IL-33,IL-37,NLRP3 and NK/DC ratios were 0. 705(95%CI：0. 404-1. 123),0. 690(95%CI：0. 372-1. 057),0. 670(95%CI：0. 378-1. 043)and 0. 685(95%CI：0. 415-1. 107),and the maximum area under the curve of combined detection was 0. 895(95%CI：0. 532-1. 216). Compared with single detection,combined detection had higher specificity and sensitivity. Conclusions The patients with CHB are often accompanied by the high expression of serum IL-33,IL-37 and NLRP3,and the NK/DC ratio will be significantly reduced. IL-33,IL-37,NLRP3 and NK/DC ratio are correlated with the condition of patients with CHB,and can also predict the condition of patients.

Objective To explore the correlation of cytochrome P450 gene (CYP2C19) polymorphism with hypersensitive C-reaction protein (hs-CRP), interleukin-6 (IL-6) and prognosis in patients with acute myocardial infarction (AMI). Methods A total of 182 patients with AMI admitted to cardiology department from May 2019 to May 2020 were selected as the research objects, all subjects underwent percutaneous coronary intervention (PCI), and CYP2C19 gene polymorphism in peripheral blood was detected by RT-PCR, which was grouping basis. One day after taking aspirin 300 mg and clopidogrel 300 mg orally, the levels of hs-CRP and IL-6 in patients' plasma were measured. The major adverse cardiovascular events (MACE) were followed up for 12 months after treatment. Results Among 182 patients with AMI, 78 patients (42.8%) were in the fast metabolism group (CYP2C19*1/*1), 65 patients (35.7%) in medium metabolism group (CYP2C19*1/*2, CYP2C19*1/*3), 39 patients (21.5%) in the slow metabolism group (CYP2C19*2/*2, CYP2C19*2/*3, CYP2C19*3/*3).Compared with the fast metabolism group, hs-CRP and IL-6 levels in the medium and slow metabolism group were significantly higher (P<0.05); compared with the medium metabolism group, hs-CRP and IL-6 levels in the slow metabolism group were significantly increased (P<0.05). CYP2C19 genotype was positively correlated with hs-CRP and IL-6 levels (r=0.163, 0.175,P<0.05). The incidences of MACE in the medium and slow metabolism groups were higher than that in the fast metabolism group (P<0.05). Conclusion CYP2C19 genotypes were associated with hs-CRP and IL-6 levels. Medium and slow metabolism types of CYP2C19 gene can activate the inflammatory response and affect the clinical prognosis of patients with AMI.
