"On the other hand however, the international assistance, the assistance and support from our partners, was very essential for enrooting the democracy in Ukraine."
尤先科说：“令我尤其高兴的是，我看到了乌克兰总统不是由莫斯科或者华盛顿决定的，而是由乌克兰人自己决定的。但是在另一方面，国际协助，来自我们伙伴的协助对民主在乌克兰生根起了十分关键的作用。”
"I don't view relations as one where there is a scorecard that says, if we all fight terror together, then somebody owes somebody something," he said. "This is a world in which co-operation is essential. And mutual cooperation is really essential between Pakistan and the United States."
布什说：“我不认为我们的关系中有这样一种规定，就是说如果我们一起打击恐怖主义，那么某个人就欠某个人什么东西。合作在这个世界上非常重要。对于巴基斯坦和美国来说，相互合作至关重要。”

Organic anxiety disorder
A disorder characterized by the essential descriptive features of a generalized anxiety
disorder (F41.1), a panic disorder (F41.0), or a combination of both, but arising as a
consequence of an organic disorder.
Excludes: anxiety disorders, nonorganic or unspecified (F41.-)

表徵为其特徵的疾病 ， 但是由於器质性疾病所产生
。
不包含 ： 焦虑症 ， 非器质性或未明示的 (F41.-)
F41 .0
Panic disorder [episodic paroxysmal anxiety]
The essential feature is recurrent attacks of severe anxiety (panic), which are not
restricted to any particular situation or set of circumstances and are therefore
unpredictable. As with other anxiety disorders, the dominant symptoms include sudden onset
of palpitations, chest pain, choking sensations, dizziness, and feelings of unreality
(depersonalization or derealization). There is often also a secondary fear of dying,
losing control, or going mad. Panic disorder should not be given as the main diagnosis if
the patient has a depressive disorder at the time the attacks start; in these
circumstances the panic attacks are probably secondary to depression.
Panic:
. attack
. state
Excludes: panic disorder with agoraphobia (F40.0)
恐慌症 （ 阵发性突发焦虑 ）
基本现象是重覆发作的严重焦虑 ( 恐慌 ) ， 其发生不
限於任何情境或环境 ， 所以是不可预期的。和其他
焦虑症一样 ， 主要症状是突然的心悸、胸痛、窒息
感 ， 头晕和不真实感 （ 自我感丧失或现实感丧失 ）
等。有次发性的害怕死亡、失去控制或发狂。若恐
慌发作时同时有郁症 ， 则不应诊断恐慌症 ， 因为它
可能是郁症之续发症状而已。
恐慌发作或恐慌状态
不包含 ： 伴有惧旷之恐慌症 （F40.0) 。
F42
Obsessive-compulsive disorder
The essential feature is recurrent obsessional thoughts or compulsive acts. Obsessional
thoughts are ideas, images, or impulses that enter the patient's mind again and again in a
stereotyped form. They are almost invariably distressing and the patient often tries,
unsuccessfully, to resist them. They are, however, recognized as his or her own thoughts,
even though they are involuntary and often repugnant. Compulsive acts or rituals are
stereotyped behaviours that are repeated again and again. They are not inherently
enjoyable, nor do they result in the completion of inherently useful tasks. Their function
is to prevent some objectively unlikely event, often involving harm to or caused by the
patient, which he or she fears might otherwise occur. Usually, this behaviour is
recognized by the patient as pointless or ineffectual and repeated attempts are made to
resist. Anxiety is almost invariably present. If compulsive acts are resisted the anxiety
gets worse.
Includes: anankastic neurosis
obsessive-compulsive neurosis
Excludes: obsessive-compulsive personality (disorder) (F60.5)
强迫症
基本的特徵是反覆的强迫性思考或强迫性行动。强
迫性思考是指意念、心象或冲动以一种刻板的方式
， 一次又一次的进入病人的思绪当中。这些通常是
令人困扰的 ， 病人通常会试着去抵抗上述意念 ， 但
都不会成功。这些意念一向被病人认为是自己的思
考 ， 纵使他们是非志愿或厌恶的。强迫性行动或仪
式行动是一种刻板的行为 ， 被一次又一无可奈何次
的重复。这些并不令人感到愉快 ， 也不能达成有用
的任务。病人通常把这些行动视为是一种用来避免
在客观上并不可能发生的对患者或他人的伤害 ， 这
些行为通常会被病人认为是没有意义的或亳无作用
的 ， 而且屡次地想来抵抗此行动 ， 同时会有焦虑。
若试图抵抗此重覆行为 ， 焦虑会加重。
包含 ： 强迫性精神官能症 （anankastic neurosis）
强迫性精神官能症 （obsessive-compulsive neurosis）
不包含 ： 强迫性人格障碍症 （F60.5）
F45.2
Hypochondriacal disorder
The essential feature is a persistent preoccupation with the possibility of having one or
more serious and progressive physical disorders. Patients manifest persistent somatic
complaints or a persistent preoccupation with their physical appearance. Normal or
commonplace sensations and appearances are often interpreted by patients as abnormal and
distressing, and attention is usually focused upon only one or two organs or systems of
the body. Marked depression and anxiety are often present, and may justify additional
diagnoses.
Body dysmorphic disorder
Dysmorphophobia (nondelusional)
Hypochondriacal neurosis
Hypochondriasis
Nosophobia
Excludes: delusional dysmorphophobia (F22.8)
fixed delusions about bodily functions or shape (F22.-)

表示。正常或平常的感觉和外貌常被病人解释为不
正常的 ， 令他自感困扰。注意的焦点常集中在身体
的一、二个器官或系统上。病人常有显着的忧郁及
焦虑现象 ， 且可能符合这些疾病的诊断。
