In 6~ 9 months following stents implantation, the results of the mean lumen in the stenosis segment, Borg index, FVC, FEV1 and PEF indicate that the long-term effect maintains at a satisfactory level.

在支架植入后6~9个月，分别测定狭窄段气道腔径、气促指数、FVC、FEV1及PEF，显示其疗效依然维持在一个较为理想的状态。

Results UIP occurred more often in males over 50 years of age. Clinical findings included progressive shortness of breath, cough, sputum and crackles over both lung fields.

结果UIP多见于50岁以上的男性，临床主要表现为活动后气促、咳嗽咳痰、双下肺闻及吸气相爆裂音；

The main clinical manifestations for recurrent wheezing, dyspnea, chest tightness or coughing.

临床主要表现为反复发作的喘息、咳嗽、气促、胸闷等症状，常在夜间和（或）清晨发作或加剧。

In both cases can lead to shortness of breath.

以上两种情况均可导致气促。

Statistical analysis the gender, age, course of cough, course of shortness of breath, symptom score of TCM, BODE, pulmonary function between groups.

对组间性别、年龄、咳嗽病程、气促病程、中医症状计分、BODE指数、肺功能等基本情况进行统计分析。

Conclusions The clinical features of drug addicts with IE are: fever, inertia, panting, coughing, cardiac souffle, positive of blood germiculture and pulmonary infection. Echocardiogram is important to diagnosing the infection of tricuspid valve.

结论静脉药瘾并发IE者临床特征为发热、咳嗽、气促，心脏杂音，血细菌培养阳性合并肺感染，超声心动图检查对右心感染有重要价值。

After treatment, the pH value, PaCO 2 and PaCO 2 were significantly improved in experimental group with less short-breath symptom.

治疗后pH、PaO2和PaCO2两组均有统计差异；患者气促症状减轻，临床症状改善。

Palpitation, Panting and Swallen in Lower Limbs for A Month

心悸、气促、下肢浮肿1月

Symptoms as shortness of breath, limb weakness, nausea, vomiting, syncope, chest tightness, dizziness, heart palpitations and pericardial effusion were more likely to happen in Type-A AD than Type-B AD, the difference was statistically significant ( P0.05).

A型主动脉夹层与B型相比较，更易出现气促、四肢乏力、恶心呕吐、晕厥、胸闷、头晕、心悸等症状，心包积液也更常见，差异有统计学意义（P0.05）。

Cough and expectoration were found in 6 cases Breathlessness was found in 2 cases.
