Objective To explore the risk factors of unplanned readmission in patients with acute myocardial infarction in plateau area. Methods The convenience sampling method was used to select 220 patients with acute myocardial infarction in the hospital's internal medicine department from January 2020 to May 2021. The patients were divided into two groups according to whether they had unplanned readmission within one year, 79 patients were included in readmission group, and 141 patients without unplanned readmission were included in non-readmission group. Clinical data of the 220 patients with acute myocardial infarction in plateau area were collected by reviewing electronic medical records, and laboratory examination and angiography examination were performed 1 day before discharge. Univariate and multivariate logistic regression analysis were carried out, and ROC curve risk prediction model was established. Results There were statistically significant differences in age, history of myocardial infarction, history of PCI, history of stroke, blood calcium, and Kilip cardiac function between the two groups (P < 0.05). Logistic regression analysis showed that age ≥60 years old, history of myocardial infarction, history of PCI, history of stroke, blood calcium and Kilip cardiac function grading were positively correlated with unscheduled readmission (P < 0.05). The ROC curve was drawn with the occurrence of unplanned readmission as the state variable. The AUC area was 0.801, the predictive sensitivity was 88.94%, and the specificity was 57.92%. Conclusion Unplanned readmission of AMI patients in plateau areas is related to multiple factors. It is necessary to identify high-risk groups as early as possible in combination with risk factors and develop individualized intervention measures.

Objective To investigate the effect of citric acid and ambroxol on clearing insoluble particles of depleted uranium in rat lungs by establishing a tracheal perfusion model.Methods One hundred and fifty male Wistar rats were randomly divided into model exposure group, normal control group(NC group), depleted uranium exposure group(DU), citric acid treatment group( CA) , ambroxol treatment group( AM) and citric acid+ambroxol treatment group( CA+AM) . The rats were sacrificed on 7, 15 and 30 days.Uranium content in the lungs was detected by microwave digestion method, pathological changes in the lungs were observed, and inflammatory factors of lung homogenates were detected.Results Compared to DU control group, the intrapulmonary uranium deposit amount in experimental groups was significantly reduced on 7 and 15 days (P<0.05).HE stained lung tissue showed that the pathological changes in treatment groups were less significant than in DU control group.The level of IL-1α,IL-1β,and IL-2 was significantly lower than in DU control, but the level of MCP-1 and MIP-1 was observably higher.Conclusion Citric acid and ambroxol can evidently improve the clear-ance of lung uranium and reduce damnification of lung tissues.Drug treatment can reduce the level of pulmonary inflamma-tory cytokines alleviate the chronic inflammation in the lungs, and enhance the capacity of macrophage to recruitment.
