Vitros 350 autoanalyzer

For each patient, urine was collected over a 24-h period (24-h urine), using a jug that contained preservative (2 mL methylbenzene) to prevent bacterial growth. The initial urine was removed at 7:00 am, and the 24-h urine was collected in the jug until 7:00 am the next day. The 24-h urine samples were collected on the first day (d), third day, first week (week; first day after operation), third week, fourth week, sixth week, eighth week and twelfth week from fracture patients in group A. For patients in group B, 24-h urine samples were collected on the first day, third day, first week, third week, fourth week, sixth week, eighth week and twelfth week after hospitalisation. Subsequently, the urine calcium in the two groups was detected using a Vitros 350 autoanalyzer (Johnson-Johnson, NY, USA). The changes in urine calcium levels were evaluated according to fracture location, fracture type, age and gender. Additionally, the distribution of hypercalciuria in groups A and B at the different time points was also analysed.

COVID-19 patients infected by the omicron variant of SARS-CoV-2 were hospitalized and treated as reported (17 (link)). Blood cell analysis was conducted by an automated XN1000 hematology analyzer (SYSMEX, Japan), and biochemical indicators were analyzed using VITROS 350 autoanalyzer (Johnson &. Johnson, USA). Computed tomography (CT) was performed using BrightSpeed 16 CT Scanner (GE Healthcare, USA). The scanning parameters were set as 120 kVp, 80 mA, 1.5-mm collimation, reconstruction matrix of 512 × 512, slice thickness of 5.0 mm, scan field of view (FOV) of 25 × 25 cm, and high spatial resolution algorithm. For most of admitted COVID-19 patients in TFPHS, two types of inactivated vaccines (Sinovac or Sinopharm) have been administered. Serological tests of patients based on detection of SARS-CoV-2-specific immunoglobulin M (IgM) and immunoglobulin G (IgG) were conducted, using 2019-nCoV Ab test kit (colloidal gold), manufactured by Innovita Biological Technology Co. Ltd., China.
