Management of Acquired Aural Atresia and Stenosis: A Case Series.

Acquired aural atresia and aural stenosis have high recurrence rates, which are challenging for ear, nose, and throat surgeons. This study aimed to discuss the management of acquired aural atresia and aural stenosis to obtain favorable outcomes. Four representative cases of different etiologies are presented, and a related literature review was conducted.

Fluvial fan sedimentary characteristics of distributive fluvial system.

The characteristics of fan sediment in the distributive fluvial system are evaluated based on a thorough analysis of modern silt in the Guertu river distributive fluvial system, as well as data obtained from UAV aerial photography and satellite remote sensing. The Guertu River Distributive Fluvial System (DFS) is classified into three stages, namely "proximal," "middle," and "distal," based on the examination of river morphology, sediment variations, sedimentary attributes, and other relevant aspects throughout different sections of its tributaries, from the source to the mouth. At the upstream section of the downstream fining sequence, the slope is the steepest and the hydrodynamic conditions are intense, resulting in the formation of a predominantly big gravel braided river.

Analysis of Occurrence Characteristics and Influencing Factors of Out-of-Hospital Induced Stress Injury in Patients with Community-Acquired Pneumonia in Respiratory Intensive Care Unit.

Background: We aimed to evaluate the characteristics of a stress injury in community-acquired pneumonia (CAP) patients in the respiratory intensive care unit (RICU) and analyze the risk factors, to provide evidence for clinical prevention and treatment.

Methods: This retrospective study was conducted in RICU at Qilu Hospital of Shandong University, China. We selected 85 patients with traumatic CAP who were brought in from January 2019 to December 2020 as the case group and 167 patients without traumatic CAP hospitalized in the same period as the control group.

Diagenetic evolution of the Oligocene Huagang Formation in Xihu sag, the East China Sea Shelf Basin.

The deep and ultra deep clastic reservoir is characterized by strong reservoir heterogeneity and complicated reservoir-forming characteristics for its high degree of diagenetic stage and the complexity of diagenesis. In order to better study the diagenetic evolution of deep and ultra deep reservoir in the burial process, a fine subsection scheme of 36 diagenetic micro-stage (DS) in diageneitic process was proposed based on paleotemperature (T), vitrinite reflectance (Ro%) and proportion of smectite in illite/smectite interstratified minerals (I/S-S%). Taking the Oligocene Huagang Formation in the Xihu sag of the East China Sea Basin as an example, the diagentic stage IIA1-IIA2-IIB was identified mainly by means of formation temperature data (T), homogenization temperature of fluid inclusion (Th), vitrinite analysis and clay mineral X-ray diffraction method.

The emergence of coronary heart disease in populations of Chinese descent.

Most countries in oriental Asia have not yet experienced the 'western' coronary heart disease (CHD) epidemic despite substantial economic development. An exception has been Singapore. We compared mortality and CHD risk factors in Singapore with two Oriental locations, Hong Kong and mainland China, which have not experienced the CHD epidemic.
