Imaging characteristics and ECG distribution of coronary fistulas: The first large-scale study.

Background: The proportion of abnormal electrocardiogra (ECG) in patients with coronary artery fistula (CAF) is relatively high, but the correlation between CAF and arrhythmia is mostly reported in individual case studies. This paper analyzes the correlation between imaging features and ECG features.

Objective: This paper aims to analyze the incidence and distribution characteristics of abnormal ECG in patients with CAF and further explore the difference in ECG characteristics between coronary-cameral fistula (CCF) and coronary-pulmonary artery fistula (CPAF).

Ecological security assessment and ecological pattern optimization for Lhasa city (Tibet) based on the minimum cumulative resistance model.

The alpine regions of Tibet are biogeographically unique and highly biodiverse. As the political, economic, and cultural center of Tibet, the city of Lhasa's population growth and economic development have further weakened the region's already fragile ecological environment. Coordinating relationships between stable economic development, sustained population growth, rational resource use, and environmental protection has become an urgent issue.

Unusual case of a right atrial inflammatory myofibroblastic tumor presenting with an episodic cyanosis in an infant.

Cardiac inflammatory myofibroblastic tumor (IMT) is a rare benign tumor that occurs mainly in infants and children. We report a case of right atrial IMT in a 1-month-old girl with episodic cyanosis. Both echocardiography and cardiac computed tomography revealed a right atrial mass.

Study on the spatial changes concerning ecosystem services value in Lhasa River Basin, China.

In this study, the outcome serves to establish a measurement model to calculate the value of ecosystem services in Lhasa River Basin, China. Following on the principle of resource scarcity, a study paradigm is established according to the influence of natural and socio-economic location differences on the value of ecosystem services. Results show that the total value of ecosystem services in Lhasa River Basin is 104.

The developmental difference of inattentional blindness in 3-to-5-year-old preschoolers and its relationship with fluid intelligence.

Preschoolers can focus on the events that they are interested in and shield other information that may still be obvious and important, and this phenomenon is termed as inattentional blindness (IB). The present study investigated the developmental differences in IB and explored its relationship with fluid intelligence in 3-to-5-year-old preschoolers. With the involvement of one hundred and thirty-five preschoolers, it was found that the IB rates decreased with age during 3-to-5-year-olds.

Accuracy of cardiac CT in evaluating severity of left atrial appendage spontaneous echo contrast: comparison with transesophageal echocardiography.

To investigate the capacity of biphasic cardiac CT (CCT) for qualitative and quantitative evaluation of different grades of left atrial appendage spontaneous echo contrast (LAASEC). The study included 267 inpatients with confirmed atrial fibrillation who underwent both CCT and transesophageal echocardiography (TEE). CT numbers for LAA, ascending aorta (AA), and left atrium (LA) were identified, and ROC curves for LAA, LAA/AA, and LAA/LA were plotted.

Intrathecal lentivirus-mediated transfer of interleukin-10 attenuates chronic constriction injury-induced neuropathic pain through modulation of spinal high-mobility group box 1 in rats.

Background: Neuropathic pain is a complex state of chronic pain that is usually accompanied by peripheral and central nervous system damage or dysfunction. Previous studies have indicated that neuroinflammation in the spinal cord is an important contributor to neuropathological and behavioral abnormalities. A series of early inflammatory markers, such as IL-1, TNF-α, and IFN-γ, and advanced inflammatory markers, such as high-mobility group box 1 (HMGB1), are involved in neuroinflammation.
