Objective:To advance the understanding of posterior reversible encephalopathy syndrome (PRES) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:The medical history, diagnosis and treatment process, laboratory examination and imaging examination results of a patient who developed PRES after undergoing allo-HSCT at Changhai Hospital of Naval Medical University in November 2022 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was a 33-year-old woman, and she was admitted to the hospital with 17 years of diagnosis of aplastic anemia, 1 month after sibling-matched allo-HSCT, with low-grade fever for 1 week. On the 7th day of hospitalization, the patient experienced a sudden onset of seizures. After combining findings from cranial magnetic resonance imaging (MRI) and other relevant examinations, organic brain lesions were ruled out, and PRES was considered. The patient's condition improved after receiving antihypertensive, antiepileptic, anti-infection, and other appropriate treatments. A follow-up cranial enhanced MRI was performed 3 months after the onset of symptoms revealed the disappearance of lesions.Conclusions:PRES after allo-HSCT has the potential to yield favorable outcomes when it is promptly diagnosed and treated.

Objective To evaluate the cost-utility of tiotropium/olodaterol in treating Chinese patients with moderate to very severe chronic obstructive pulmonary disease(COPD)and to provide references for selecting more economical inhaled preparations in clinical practice.Methods A four-state lifetime Markov model was established with a 3-month cycle.The health outcomes included life years and quality-adjusted life years.Costs,including direct medical costs,were calculated from the perspective of the Chinese health system.Discontinuation rates were derived from the discontinuation curve using GetData Graph Digitizer.The main output indicator of the model was the incremental cost-utility ratio,which was calculated from the queue simulation results to judge the economy of tiotropium bromide/odataterol.The scenario analysis and sensitivity analyses were carried out to detect the robustness of the base case result.Results Compared with tiotropium bromide,the patient treated with tiotropium bromide/odataterol gained an additional 0.0846 life years,an additional cost of ￥3 201.50,and additional 0.029 6 QALY.The incremental cost-utility ratio was 108 140.11 yuan/QALY,lower than the willingness-to-pay threshold of three times China's per capita GDP in 2021.The costs of tiotropium bromide and tiotropium bromide/odataterol had the greatest impact on the result in the one-way sensitivity analysis.93.8%of the Chinese COPD population was willing to pay for tiotropium bromide/odataterol under the threshold in the probability sensitivity analysis.Conclusion Tiotropium/olodaterol is a cost-effective alternative compared to tiotropium for patients with moderate to very severe COPD in China and the results were robust in the sensitivity analyses.
