Objective: To analyze the influencing factors for anterior tibial artery atherosclerosis among patients with hyperuricemia, so as to provide insights into the prevention of anterior tibial artery atherosclerosis. Methods: Patients aged 18 years and older with hyperuricemia in Dazhou Integrated TCM & Western Medicine Hospital were enrolled as research subjects from 2020 to 2023. Demographic information and blood biochemistry indicators were collected through electronic medical records. Anterior tibial artery atherosclerosis was evaluated by color Doppler ultrasound. Factors affecting anterior tibial artery atherosclerosis among patients with hyperuricemia were analyzed by a multivariable logistic regression model. Results: A total of 1 105 patients with hyperuricemia were surveyed, including 862 males (78.01%) and 243 females (21.99%). There were 918 cases (83.08%) at the ages of 60 years and older, and 457 cases (41.36%) with a course of disease at 10 years and longer. The median level of blood uric acid was 480.79 (interquartile range, 98.28) μmol/L. There were 314 cases (28.42%) with anterior tibial artery atherosclerosis. Multivariable logistic regression analysis showed that body mass index (≥24.0 kg/m2, OR=1.597, 95%CI: 1.185-2.151), long-term smoking history (yes, OR=1.709, 95%CI: 1.153-2.534), diabetes mellitus (yes, OR=1.517, 95%CI: 1.162-1.981), serum uric acid (≥480.79 μmol/L, OR=1.667, 95%CI: 1.131-2.457), serum creatinine (≥97 μmol/L, OR=1.685, 95%CI: 1.155-2.460), fasting blood glucose (≥6.1 mmol/L, OR=1.528, 95%CI: 1.106-2.112), fibrinogen (>4 g/L, OR=1.589, 95%CI: 1.091-2.315) and triglycerides (≥1.7 mmol/L, OR=1.879, 95%CI: 1.226-2.881) were influencing factors for anterior tibial artery atherosclerosis among patients with hyperuricemia. Conclusion Anterior tibial artery atherosclerosis among patients with hyperuricemia is associated with long-term smoking, diabetes mellitus, serum uric acid, serum creatinine, fasting blood glucose, fibrinogen and triglycerides high level.

Objective: To discuss the rational drug application of Kawasaki disease in children with upper respiratory tract infection in order to provide reference for the therapy of Kawasaki disease suspected of bacterial meningitis.Methods: The medical record of a 2-year-old boy with Kawasaki disease was retrospectively analyzed, and the anti-infection treatment was analyzed and evaluated.Meanwhile, the mechanism of elevated leukocyte count in cerebrospinal fluid (CSF)of children with incomplete Kawasaki disease was discussed.The pharmaceutical care and treatment results in the diagnosis and treatment process were analyzed as well.Results: The anti-infective therapy in early stage was reasonable as the early symptoms of respiratory tract infection in the child were obvious, however, the choice of aztreonam was defective.On the premise of the clinical diagnosis of Kawasaki disease and excluding bacterial meningitis, the medication was timely adjusted.Finally, the symptoms of the child were improved.Conclusion: The application of anti-infection drugs should be reasonable in clinics, and the abnormality in cerebrospinal fluid should be paid more attention in children with Kawasaki disease.It is necessary to strengthen clinical observation and pharmaceutical care in order to guarantee the safety of medication for patients.
