“…Inappropriate interventions, such as biopsy or fine-needle aspiration of vascular lesions, can have devastating consequences, and in some cases, lead to massive intra-pulmonary bleeding and even death[ 7 , 10 ]. Among the vascular malformations of the bronchus, there are relatively more reports of Dieulafoy's disease[ 11 ]. There are even fewer reports of PA aneurysms presenting as endobronchial masses, which rarely protrude into the airway lumen.…”

β cells are the main cells responsible for the hypoglycemic function of pancreatic islets, and the insulin secreted by these cells is the only hormone that lowers blood glucose levels in the human body. β cells are regulated by various factors, among which neurotransmitters make an important contribution. This paper discusses the effects of neurotransmitters secreted by various sympathetic and parasympathetic nerves on β cells and summarizes the mechanisms by which various neurotransmitters regulate insulin secretion. Many neurotransmitters do not have a single source and are not only released from nerve terminals but also synthesized by β cells themselves, allowing them to synergistically regulate insulin secretion. Almost all of these neurotransmitters depend on the presence of glucose to function, and their actions are mostly related to the Ca2+ and cAMP concentrations. Although neurotransmitters have been extensively studied, many of their mechanisms remain unclear and require further exploration by researchers.

Rationale: Dieulafoy disease of the bronchus is a rare vascular deformity. To the best of our knowledge, reports of these involving both lung vascular are hitherto absent.Patient concerns: A 67-year-old male was admitted to our department due to agnogenic hemoptysis.Diagnoses: Bronchoscopy was performed and some smooth, pulsatile nodular lesions were found in the middle and lower lobes, Computed tomography angiography of the bronchial artery confirmed a left bronchial artery arising from the aortic arch at T4 level, and both bronchial arteries were dilated and tortuous.Interventions: Bronchial artery embolization was performed successfully.Outcomes: The patient was discharged with no hemoptysis. In addition, patient is under follow-up until today without any further incidents.Lessons: This case reminds us that Dieulafoy disease of the bronchus could be a potential etiology for unexplained hemoptysis. The clinician should be aware of this disease when bronchoscopy revealed multiple some smooth, pulsatile nodular lesions, thereafter, bronchoscope biopsy should be avoided, as it could lead to fatal hemoptysis.Abbreviations: CT = computed tomography, INR = international normalized ratio, NBI = narrow band imaging, PT = partial thromboplastin time.
