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 investigate relationship between nutritional status and activities of daily living(ADL) in elderly inpatients in Guangzhou. Methods Total of 275 people older than 60 were included in this study from Guangzhou First People's Hospital from July 2018 to June 2019. Their nutritional markers(including BMI, plasma albumin, hemoglobin, total cholesterol, triglyceride),the activities of daily living(ADL) were evaluated with Barthel index and the nutrition risk screening 2002(NRS2002)used to assess the nutritional risk status were collected to analyze the relationship between nutrition and ADL. Results In these subjects, based on the NRS2002 scores(nutritional risk that the NRS2002 scores were equal or greater than 3, and the non-nutritional risk that the NRS2002 scores were less than 3),58.9%(162/275) patients were having nutritional risk and 41.1%(113/275) were having non-nutritional risk. In elderly inpatients,NSR2002 were negatively associated with ADL(r=-0.393,P＜0.05). ADL was positively associated with BMI, plasma albumin and hemoglobin level(P<0.05). Conclusion In the old, the NRS2002 is an influencing marker of activities of daily living in Guangzhou. Reducing the nutritional risk by lowering the NRS2002 scores can improve ADL in the elderly. The incidence of nutritional risk is highly prevalent in elderly and early nutritional treatment will be needed.
