Objective To observe the airway remodeling in the respiratory tract of asthmatic SD rats models and the expression of MMP-9/TIMP-1 and compared with the dexamethasone control group in order to find the mechanism of antiasthmatic pills in healing asthma.

目的：通过二次致敏，制成大鼠哮喘模型，探讨气道重塑与MMP-9/TIMP-1表达的关系及平喘丸的干预作用并与地塞米松相对照，力图掀开平喘丸治疗哮喘的机理。

Dr. Antonella Casola from Uniersity of Texas Medical Branch, Galeston, and colleagues inestigated the effect of antioxidant administration on RS-induced lung inflammation, clinical disease, and airway hyperreactiity in a mouse model.

位于加尔维斯顿的德克萨斯大学医学部的Antonella Casola博士和他的同事们在一个小鼠模型上研究了抗氧化剂对RS引起的肺部炎症、临床疾病和气道高反应性的影响。

Obstructive sleep apneal/hyponea syndrome patients, no matter whether complicated by cardiovascular diseases or not, have significant vascular endothelial cell dysfunction, which can be improved through the continuous positive airway pressure treatment.

阻塞性睡眠呼吸暂停／低通气综合征患者无论是否合并心脑血管疾病，血浆一氧化氮、内皮素1和可溶性P选择素均存在明显异常；而持续气道正压通气治疗可有效纠正其异常。

Respiratory system impedance was measured continuously over a 90-s apneic period innave and rabbits sensitized to allergens by ovalbumin.

在没有处理过的家兔和已经对卵清蛋白的变应原致敏家兔，连续测定呼吸暂停的90s 内的呼吸系统的气道阻抗。

Methods The patients with ventilator were divided into four groups according to the type of the heated humidifier (MR410,MR730)and ambient temperature(26 ℃～28 ℃,18 ℃～20 ℃),then the temperature of the inlet chamber,the temperature and humidity of the outlet chamber and the aspiratory chamber and the airway secretions characteristics of each group were compared.

方法根据湿化器类型(MR410、MR730)、环境温度的高低(26℃～28℃、18℃～20℃)将应用呼吸机治疗的患者分为四组，比较各组间湿化器输入端温度、输出端温度和湿度、吸入端温度和湿度，并比较各组患者气道分泌物的性状。

Objective To investigate the association of bacteriologic characteristics and bacterial infection in small airway disease.

目的 研究慢性阻塞性肺疾病细菌学特征、细菌感染与小气道病变的关系。

The air trapping volume had an obvious correlation with FEF50% and MMEF(X^2=10.48, P.01). Conclusions: The CT manifestations of prognosis are demonstrated later than bacteriology. There is a limitation in assessing the activity of pulmonary tuberculosis only by CT signs. CT plays a role in demonstration of secondary small airway changes after bacteriologically cured.

肺结核CT征象转归滞后于细菌学转归，仅凭CT征象对治疗后肺结核活动性判定存在限度；CT对肺结核细菌学治愈后的继发小气道病变的评价有较高价值。

Results The compounded gum was combined with bletilla hyacinthine gum and PVA in the proportion of 5:1 so that its adhesive ability and membrane forming ability were suitable for giving medicine through airway.

在临床工作中，由于全身用药对肺局限性病灶常存在穿透力不够而在局部无法达到有效浓度的情况，往往需要采用从气道内直接给药的方法，如厚壁结核空洞、局灶性化脓性病变等[1 ] 。

With its remedial effects and good property, the carrier of natural aborable and non-poisonons, innocuous bletilla hyacinthine gum is of better value in clinical application than pure chemical carrier that had previously been used.

近些年来，有报道采用聚乙烯醇配制药液注入的方法，在一定程度上克服了一般溶液的不足，但实验证明，PVA作为载体虽然成膜性较好，但粘附性差，注入后仍易被咳出，加之其无法被机体生物降解吸收，滞留气道及易引起意外阻塞性副反应，故仍不

"Zhikuoning Mixture" can suppress the over-expression of MMP-9 mRNA in bronchiectatic rats, which may be one of the mechanisms of its therapeutical efficacy and worthy of further study.

支扩宁合剂可抑制支气管扩张症气道中MMP-9 mRNA表达，这可能是其疗效机制之一，值得进一步研究。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
