A study of more than 5,000 children in Southern California found that those kids who lived within 250 feet (76 meters) of busy roads had a 50% higher risk of having had asthma symptoms in the past year. The researchers found that the asthma risk decreased to normal for children living about 600 feet or more away from a busy road. The greatest risk of asthma symptoms was found in children who had lived near busy roads since before age 2.
①Asthma is a disease of the human respiratory system in which the airways narrow, often in response to a "trigger" such as exposure to an allergen, cold air, exercise, or emotional stress.This narrowing causes symptoms such as wheezing, shortness of breath, chest tightness, and coughing, which are the hallmarks of asthma. Between episodes, most patients feel fine.
The disorder is a chronic inflammatory condition in which the airways develop increased responsiveness to various stimuli, characterized by bronchial hyper-responsiveness, inflammation, increased mucus production, and intermittent airway obstruction. The symptoms of asthma, which can range from mild to life threatening, can usually be controlled with a combination of drugs and lifestyle changes.
Public attention in the developed world has recently focused on asthma because of its rapidly increasing prevalence, affecting up to one in four urban children.②Susceptibility to asthma can be explained in part by genetic factors, but no clear pattern of inheritance has been found. ③Asthma is a complex disease that is influenced by multiple genetic, developmental, and environmental factors, which interact to produce the overall condition.
④During an asthma episode, inflamed airways react to environmental triggers such as smoke, dust, or pollen. The airways narrow and produce excess mucus, making it difficult to breathe.
A typical inhaler, of Serevent (salmeterol)Symptomatic control of episodes of wheezing and shortness of breath is generally achieved with fast-acting bronchodilators. These are typically provided in pocket-sized, metered-dose inhalers (MDIs—see the image to the right). In young sufferers, who may have difficulty with the coordination necessary to use inhalers, or those with a poor ability to hold their breath for 10 seconds after inhaler use (generally the elderly), an asthma spacer is used. The spacer is a plastic cylinder that mixes the medication with air in a simple tube, making it easier for patients to receive a full dose of the drug (see top image) and allows for the active agent to be dispersed into smaller, more fully inhaled bits. A nebulizer—which provides a larger, continuous dose—can also be used. Nebulizers work by vapourizing a dose of medication in a saline solution into a steady stream of foggy vapor, which the patient inhales continuously until the full dosage is administered. There is no clear evidence, however, that they are more effective than inhalers used with a spacer. Nebulizers may be helpful to some patients experiencing a severe attack. ⑤Such patients may not be able to inhale deeply, so regular inhalers may not deliver medication deeply into the lungs, even on repeated attempts. Since a nebulizer delivers the medication continuously, it is thought that the first few inhalations may relax the airways enough to allow the following inhalations to draw in more medication.Since a nebulizer delivers the medication continuously, it is thought that the first few inhalations may relax the airways enough to allow the following inhalations to draw in more medication.
new words
respiratory system 呼吸系统
The respiratory system is the biological system of any organism that engages in gas exchange. Even trees have respiratory systems, taking in carbon dioxide and emitting oxygen during the day, consuming carbon dioxide and producing oxygen constantly.
hallmarks 外表
A mark indicating quality or excellence.
symptom 症状
A symptom may loosely be said to be a physical condition which shows that one has a particular illness or disorder (see e.g. Longman, 1995). An example of a symptom in this sense of the word would be a rash. However, correctly speaking, this is known as a sign, as would any indication detectable by a person other than the sufferer in the absence of verbal information from the patient.
dyspnea 呼吸困难
Dyspnea (Latin dyspnoea, Greek dyspnoia from dyspnoos - short of breath) or shortness of breath (SOB) is perceived difficulty breathing or pain on breathing. It is a common symptom of a great many disorders.
epidemiology 流行病学
In epidemiology, the prevalence of a disease in a statistical population is defined as the ratio of the number of cases of a disease present in a statistical population at a specified time and the number of individuals in the population at that specified time.
Genetics 遗传学
Humans began applying knowledge of genetics in prehistory with the domestication and breeding of plants and animals. In modern research, genetics provides important tools for the investigation of the function of a particular gene, e.g., analysis of genetic interactions. Within organisms, genetic information generally is carried in chromosomes, where it is represented in the chemical structure of particular DNA molecules.
Inheritance 遗传
Inheritance is the practice of passing on property, titles, debts, and obligations upon the death of an individual. It has long played an extremely important role in human societies.
hypersensitivity 过敏性
Hypersensitivity is an immune response that damages the body's own tissues.
spasm 抽搐, 痉挛
A spasm is a sudden, involuntary contraction of a muscle, a group of muscles, or a hollow organ, or a similarly sudden contraction of an orifice. A spasm is usually accompanied by a sudden burst of pain.
Inflammation 炎症
Inflammation is the first response of the immune system to infection or irritation and may be referred to as the innate cascade. Inflammation is characterized by the following quintet: redness (rubor), heat (calor), swelling (tumor), pain (dolor) and dysfunction of the organs involved (functio laesa).
mucus 黏液
Mucus is a slippery secretion of the lining of various membranes in the body (mucous membranes). Mucus aids in the protection of the lungs by trapping foreign particles that enter the nose during normal breathing. Additionally, it prevents tissues from drying out.
bronchodilator 支气管扩张
A bronchodilator is a medication intended to improve bronchial airflow. Treatment of bronchial asthma is the most common application of these drugs. They are also intended to help expand the airways and improve the breathing capacity of patients with emphysema, pneumonia and bronchitis.
inhaler 吸入器
An inhaler is a medical device used for delivering medication into the body via the lungs. It is often used in the treatment of asthma
nebulizer 喷雾器
In medicine, a nebulizer is a device used to administer medication to people in forms of a liquid mist to the airways. It is thus used in treating respiratory diseases. Also called "atomizers", they pump air or oxygen through a liquid medicine to turn it into a vapor, which is then inhaled by the patient.
