Abstract: Objective　To investigate the relationship between the body mass index (BMI) levels and the negative conversion time of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid in adult coronavirus disease 2019 (COVID-19) patients and the asymptomatic persons. Methods　Asymptomatic infected patients and confirmed COVID-19 patients admitted to Chengdu Public Health Clinic Center from February 2021 to November 2021 were dynamically included. The epidemiological and clinical characteristics of the objects were collected, and the SARS-CoV-2 nucleic acid testing of the objects during their hospitalization was continuously monitored, and the negative nucleic acid conversion time was recorded. The t test or Wilcoxon rank sum test, χ2 test or Fisher's exact probability method examine were used to distribute characteristics of each group of variables and the connection between different variables, respectively. Then the variables showed differences in distribution (P<0.05) between different BMI groups were included in the multivariate Cox proportional risk regression model. Results　A total of 253 subjects ranged from 18 to 63 years old, with M(P25, P75) age of 37.0 (30.0, 47.0) years old, were included in this study. The male to female ratio was 4.16 to 1. The BMI was (23.97±3.33) kg/m2. 50.59% (128/253) of the objects were overweight or obese, and 78.13% (100/128) were overweight. The negative time of SARS-CoV-2 nucleic acid conversion of all subjects ranged from 1 to 71 days, with M(P25, P75) of 7.0 (2.0, 18.0) days (P<0.001). The negative time of SARS-CoV-2 nucleic acid conversion of the normal weight or the thin, and the overweight or obese were 5.00 (2.00, 19.00) and 8.00 (2.00, 17.75) days respectively. The results of multivariate Cox's proportional hazards regression model showed that the BMI levels may not be associated with the negative conversion time of SARS-CoV-2 nucleic acid (HR=1.090, 95%CI: 0.843-1.410, P=0.510). Conclusions　Adult asymptomatic persons and confirmed COVID-19 patients are mainly middle-aged and young males, and overweight or obesity is relatively common. Overweight or obesity cannot be considered as an independent factor influencing the negative conversion time of SARS-CoV-2 nucleic acid.

Objective Using the third high sensitive cardiac troponin I assay to establish the reference intervals of serum cardiac marker high sensitivity cardiac troponin I ( hs-cTnI ) in apparently healthy subjects of Beijing area, and to explore the relationship between cTnI and other parameters.Methods Using random selection method, a total of 440 serum samples were collected from apparently healthy subjects of Beijing area.Among them, 217 cases were male, average age was (50.0 ±14.3) years old;223 cases were female, average age was ( 49.0 ±14.0 ) years old.All of these serum samples were detected hs-cTnI using i2000 Abott biochemical analyzer and ARCHITECT STAT Abbott assay kit.And the 99th percentile upper reference limit was used as the reference interval.Non-parametric tests were used to compare the different groups, the U Mann-Whitney test was used between two groups, the Kruskal-Wallis test was used in many groups, and the correlation analysis was used Spearman method.Results The 99th percentiles of hs-cTnI in 440 apparently healthy subjects is 9.66 ng/L.While the male group is 9.66 ng/L, and the female group is 8.25 ng/L.The serum hs-cTnI level of male is higher than female ( 9.95 ng/L vs 8.25 ng/L, P<0.05 ).According to the spearman correlation analysis, the serum hs-cTnI level appears positive correlation with age, brain natriuretic peptide (BNP), alanine aminotransferase (ALT),aspartate transaminase ( AST) ,gamma-glutamyl transferase ( GGT) ,total bilirubin ( TBIL) ,serum creatinine ( SCR) , hemoglobin (HGB)(P<0.05,R>0),and appears negative correlation with platelet (PLT)(P<0.05,R<0).Conclusion The serum hs-cTnI level apparently differents with gender, so it is necessary to establish reference intervals among different gender group of Beijing area.
