H1N1病毒
H1N1是一種病毒，是Orthomyxoviridae系列的一種病毒。它的宿主是鳥類和一些哺乳動物。幾乎所有甲型的H1N1病毒已被隔離，野生鳥類出現疾病屬罕見。有些H1N1病毒引起嚴重的疾病大多發生於家禽方面，而人類卻很少出現。但經過鳥類和哺乳動物的傳播和變異，這可能導致疫情或人類流感大面積傳播[1]。

細菌性與病毒性呼吸道感染的區別
細菌性與病毒性呼吸道感染的臨床症狀比較相似。下面六個方面是細菌性與病毒性呼吸道感染的區別。

1、病毒性感冒是由多種病毒引起的常見呼吸道傳染病。誘因有受寒、淋雨、過度疲勞、營養不良等。
2、主要表現為打噴嚏、鼻塞、流鼻涕、咽乾、咽痛、咳嗽、聲音嘶啞等症狀。表現為頭痛、渾身酸痛、疲乏無力、食慾不振等症狀。

病毒性感冒
感冒，習慣上分為病毒性感冒和細菌性感冒。或者普通感冒和流行性感冒。

The treatment of acute exacerbation of acute treatment aims to alleviate airway obstruction as soon as possible to correct hypoxemia and restore lung function, prevent further deterioration or re-attack, prevent complications. Generally based on the synthesis conditions of the sub-treatment.
1. Away from dealing with acute asthma attack triggers, we should pay attention to find predisposing factors. The majority and contact allergens, colds, respiratory infections, climate change, the consumption of inappropriate drugs (such as anti-inflammatory drugs, β receptor antagonist, etc.), lack of strenuous exercise or treatment and other factors. To identify and control triggers will help control the disease, prevention of recurrence.

Control of the disease known as anti-inflammatory drugs, or drugs. As the pathological basis of asthma, chronic non-specific inflammation, so the control of chronic airway inflammation, is the basic treatment of asthma, asthma control of long-term vision has played an important role. Commonly used drugs are inhaled corticosteroids and color TZDs. A number of new drugs, such as leukotriene modifiers, long-acting β2 agonists and theophylline controlled-release type also has certain anti-inflammatory effects.
1. Glucocorticoid glucocorticoids (the hormone) is currently the most effective drug prevention and treatment of asthma. A major role in the mechanism is to inhibit inflammatory cell migration and activation; inhibit cytokine generation; inhibit the release of inflammatory mediators; to enhance smooth muscle cell β2-adrenoceptor responsiveness. Can be divided into inhalation, oral and intravenous medication.

Bronchodilator drugs, the primary role of such drug except for the relaxation of bronchial, control of acute symptoms of asthma.
1. β2 agonists: β2 agonist drugs dozens of varieties, can be divided into three generations. ① The first generation: non-selective β2 agonist, such as adrenaline, ephedrine and isoproterenol and so on, because of cardiovascular side effects more than just being highly selective β2 agonist replaced. ② The second generation: selective short-acting β2 agonists such as albuterol (salbutamol), terbutaline (terbutaline) and phenolic C Chuanning (fenoterol) and so on, the role of time of 4 to 6 hours, the side effects on the cardiovascular system decreased significantly. ③ The third generation: a new generation of selective long-acting β2 agonist, such as (salmeterol), Fumiteluo (Formoterol) and procaterol (procaterol) and so on. Role of the time "12 hours, especially for nocturnal asthma. However, some drugs (such as salmeterol) slower onset time. In general, β2 agonists to relieve symptoms of acute attack of first-line drugs, while the second-generation drug most commonly used. The third-generation drug is mainly used in combination with the inhaled steroid, stabilize the airway and reduce the role of attack.

The success of asthma treatment goals:
1. As much as possible to control symptoms, including night-time symptoms.

Staging of bronchial asthma and severity rating:
According to clinical manifestations of bronchial asthma can be divided into acute phase and remission. Acute asthma attack period is defined as 4 weeks there between the onset of symptoms of asthma. Remission after treatment or at the end means after treatment symptoms and signs disappeared, lung function recovered to the level before acute exacerbation and to maintain more than 4 weeks.

A clinical diagnosis based on:
1. Recurrent wheezing, difficulty breathing, chest tightness or cough, more and contact allergens, cold air, physical, chemical stimulation, viral upper respiratory tract infections, exercise and other relevant.
