Objective: To study the clinical diagnosis and preoperative management of carotid body tumor.
Methods: A total of 24 cases with carotid body tumors underwent surgery from 2003 to 2013 were reviewed. The clinical and imaging features, treatment and prognosis were retrospectively evaluated. Five of the 24 patients were males and 19 were females. Twenty-three cases were benign and one case was malignant. Seven of the 24 patients had bilateral tumors.
Results: Nineteen of twenty-four patients underwent digital subtraction angiography (DSA) and temporary balloon occlusion (TBO) test, and one case of them was positive in the test. Twenty-three benign case were treated with operation. The malignant one treat with biopsy. Three cases underwent resection of tumors with both the internal and external carotid arteries without carotid reconstruction, and none of the three patients died or presented with hemiplegia after operation. Twenty-three benign cases were followed up for 6-122 months, the median was 75 months. The malignant patient died 6 months after operation.
Conclusion: TBO and DSA are reliable and practical methods to determine the safety of carotid ligation and can be used as routine preoperative examinations.

Obesity contributes to cardiometabolic risk, including subclinical atherosclerosis and insulin resistance. This study examines the predictive roles of trimethylamine N-oxide (TMAO) and resistin in relation to carotid intima-media thickness and metabolic parameters; : Sixty adults (18-71 years) with varying body weights were assessed for body composition, subclinical atherosclerosis, and blood biomarkers, including TMAO and resistin; : TMAO correlated strongly with CIMT (r = 0.674, < 0.

Background: Cigarette smoking is a strong risk factor for cardiovascular harm.
Objectives: The study sought to explore the detailed relationships between smoking intensity, pack-years, and time since cessation with inflammation, thrombosis, and subclinical atherosclerosis markers of cardiovascular harm.
Methods: We included 182,364 participants (mean age 58.

Background: Eye function is vitally dependent on an adequate blood supply, primarily provided by the ophthalmic artery, an internal carotid artery branch. This review provides an overview of the vascular supply of the eye.
Methods: A targeted search of PubMed / MEDLINE was performed using the terms "central retinal vein," "central retinal artery," "internal carotid artery," "ophthalmic artery," "ophthalmic vein," "posterior ciliary arteries," "retinal capillaries," "vascular supply of the eye," "ocular vascular supply," "external carotid artery," and "vortex vein".

Dopamine is an essential modulator of oxygen sensing and control of ventilation and is the most well described and abundant neurotransmitter in the mammalian carotid body. Little is known of the evolutionary significance of dopamine in oxygen sensing, or whether it plays a similar role in anamniotes. In the model vertebrate, zebrafish (Danio rerio), presynaptic dopamine D receptor (DR) expression was demonstrated in gill neuroepithelial cells (NECs), analogues of mammalian oxygen chemoreceptors; however, a mechanism for dopamine and DR in the gills had not been defined.
