Pyogenic liver abscess (PLA) is an infectious disease and causes high in-hospital mortality. It has no specific symptoms and is difficult to be diagnosed early in the emergency department. Therefore, early diagnosis is an urgent need for clinicians. Ultrasound has been widely used to detect lesions of PLA. However, the sensitivity of ultrasound is affected by the size and location of lesions and clinician’s experience. We conducted a retrospective study to assess the effects of early adoption of non-enhanced computed tomography (CT) scanning (i.e., receiving CT scanning within 48 hours after admission) on treatment and disease status of patients with PLA. This study enrolled 76 hospitalized patients with PLA in department of digestive disease, who received CT examination during 2014 to 2021. Of the enrolled patients, 56 received an early CT scan and 20 received a late CT scan. Results showed that the length of hospitalization in the early CT group was significantly shorter than the late CT group (15.0 days vs. 20.5 days; p = 0.035). Besides, the median time to initiating drainage after admission was also significantly shorter in the early CT group than the late CT group (1.0 days vs. 4.5 days; p

According to the structural characteristics of the plant itself, this paper Improved plant topology parsing classic language L-system and defined the basic unit of a reasonable scale. We combined basic growth unit, which consists of the chain of growth state, and ecological model. Applying C++ language to define L-system rules, rules for parsing, character iteration, physiological and ecological model program; combining with OpenGL graphics library for rendering three-dimensional structure of plant expression. Using classical topology of Botany Roux as experimental model simulation. We compare the simulation results and conventional classical model. At least, we prove this model is applicable.
