The clinical data of a child with chemical pneumonia caused by kerosene in Hainan Maternal and Children′s Medical Center in June 2019 were retrospectively analyzed.The patient was a 2 years and 1 month old boy with a history of kerosene inhalation and fever.The clinical features included low breath sounds in the left lung and dry and wet rales in both lungs.The white blood cells (WBC) level, C-reactive protein (CRP) level, and erythrocyte se-dimentation rate (ESR) were significantly increased.Chest CT showed inhalation pneumonia.Chest ultrasound suggested medium pleural effusion on the left side.The patient was given antibiotics, nebulization and other treatment.On the 12 th day of the course of the disease, his temperature returned to normal, and breath sounds on the left side were stronger than before.The WBC level, CRP level and ESR were improved according to the re-check results, but pulmonary ventilation was still obstructed mildly to moderately.Fourteen days after hospital discharge, the patient coughed less.Reexamination of chest CT prompted the lesions were further absorbed, but the mild to moderate obstructive lesions were still observed.With the reduction of kerosene use in daily life, kerosene-induced chemical pneumonia is rare, but due to its diverse and complex clinical manifestations and slow absorption of pulmonary inflammation, attention should be paid to its progression into chronic cough.

Objective To investigate the predictive value of lactate/albumin(L/A)and C-reactive protein(CRP)for 90-day mortality risk in patients with sepsis.Methods Clinical data from 125 patients diagnosed with sepsis in the Comprehensive Intensive Care Unit,Jinhua People's Hospital from February 2021 to February 2024 retrospectively were collected.According to 90-day death or not of patients,they were divided into death group(n=61)and survival group(n=64).Independent risk factors for 90-day mortality in patients with sepsis were analyzed by using multivariate Logistic regression.Receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of L/A,CRP,and L/A combined CRP for 90-day mortality in patients with sepsis.At the same time,subgroup analysis of patients was performed according to the best cut-off value,and Kaplan-Meier survival curves were drawn.Results Multivariate Logistic regression analysis showed that high CRP(OR=1.009,95％CI:1.003-1.015,P=0.006),high L/A(OR=1.449,95％CI:1.050-2.000,P=0.024),and concurrent acute kidney injury(OR=2.890,95％CI:1.198-6.975,P=0.018)were independent risk factors for 90-day mortality in patients with sepsis.Area under the curve(AUC)for predicting 90-day mortality in patients with sepsis by using CRP,L/A,and L/A combined with CRP were 0.645,0.612 and 0.708 respectively.Subgroup analysis showed that 90-day mortality of patients with sepsis in L/A＞1.41 group was significantly higher than that in L/A≤1.41 group(P=0.001),and 90-day mortality of patients with sepsis in CRP＞93.29mg/L group was significantly higher than that in CRP≤93.29mg/L group(P=0.001),which was consistent with the analysis results of Kaplan-Meier survival curve.Conclusion Both L/A and CRP have certain predictive value for 90-day prognosis of patients with sepsis,and their combined predictive effect is better.
