As shown in Table 1, we found that there were no significant differences among age, gender, body mass index (BMI), hypertension history, diabetes history, and cardiovascular diseases history, whereas AKI was significant associated with c‐reaction protein (CRP), estimated glomerular filtration (eGFR), serum creatinine (Scr), cystatin‐C (Cys‐C), neutrophil gelatinase‐associated lipocalin (NGAL), kidney injury molecule‐1 (KIM‐1), lncRNA MALAT1 level, and miR‐204 level. The gene discussed is CRP; the disease is hypertensive disorder.
