1.objective To explore the changes of gene expression of metalloproteinase-9(MMP-9) and tissue type inhibitors of metalloproteinase-1(TIMP-1) and elucidate the role of imbalance betw -een MMP-9 and its major inhibitor TIMP-1 in the renal interstitial fibrosis with unilateral ureteral obstruction, investigate the mechanisms of renal interstitial fibrosis and the preventive and theraputic effects of Regulating Collateral and Eliminating Turbidity Liquid(REL) on renal interstitial fibrosis.
目的 研究单侧输尿管梗阻(unilateral ureteral obstruction, UUO)后大鼠肾脏组织基质金属蛋白酶-9(MMP-9)、金属蛋白酶组织抑制因子-1(TIMP-1)基因的表达变化,从而探讨肾间质纤维化(renal interstitial fibrosis)的发生机制及和络泄浊方对肾间质纤维化的保护作用。
2.The aim of this study was to discuss the influence of acute biliary obstruction on liver by determining the changes of liver function markers before and after relief of acute biliary obstruction and observed the effect of EST and EML on relief of acute biliary obstruction.
本实验通过动物实验及临床研究测定急性胆道梗阻及梗阻解除后肝功能指标的变化，来探讨急性胆道梗阻早期对肝脏的影响，并观察EST和EML对治疗胆道梗阻的效果和梗阻解除后肝功能恢复情况。
3.Result:The average positive opening pressure of Eustachian tube was(23.5±8.3) daPa in expedite status,(79.8±16.2) daPa in mild obstruction,(154.1±28.7)daPa in serious obstruction and >200 daPa in entire obstruction.
结果:慢性化脓性中耳炎咽鼓管平均正压开放压在通畅时为(23.5±8.3)daPa、轻度阻塞时为(79.8±16.2)daPa、严重阻塞时为(154.1±28.7)daPa、如>200 daPa仍不开放则为咽鼓管完全阻塞。
4.Conclusion:The Eustachian tube was expedite in about 1/2 of cases with chronic suppurative otitis media,mild obstruction in about 1/4 quarter of cases,and serious obstruction and entire obstruction in about 1/10 of cases respectively.
结论:慢性化脓性中耳炎约1/2患者的咽鼓管是通畅的,轻度阻塞约占1/4,严重阻塞和完全阻塞各约占1/10。
5.Significant difference in incidence were observed between recurrent and benign group in main symptoms of intestinal obstruction, abdominal mass, uncomplete obstruction and large bowel obstruction (?P?<0 01).
两组在肠梗阻主要症状、腹部包块、不完全性肠梗阻和结、直肠梗阻的发生率上均存在显著差异（ P＜ 0－01） ；
6.The obstruction that the mere fluid receives while flowing in different medium is different, Make the velocity of flow different too, Cause and refract light the index to be different, And between size and medium molecule of obstruction effort size and medium intensive degree that member pile up have something to do.
摘要光流体在不同介质中流动时所受的阻力不同，使得流速也不同，导致折光指数不同，而阻力的大小与介质分子间作用力大小及介质分子堆积的密集程度有关。
7.Several subclassifications have been proposed: ①simple chronic bronchitis describes a condition characterized by mucoid sputum production; ②chronic mucopurulent bronchitis is characterized by persistent or recurrent purulence of sputum in the absence of localized suppurative diseases such as bronchiectasis; ③chronic bronchitis with obstruction deserves a separate classification characterized by presence of airway obstruction as assessed by the used of the forced expiratory vital capacity maneuver; and ④chronic asthmatic bronchitis.
它可以分为以下几种类型：①单纯性慢性支气管炎，其特征为咳粘液性痰；②慢性粘液脓性支气管炎，其特征是反复的或持续的咳脓痰，但肺部并无化脓性病变，如支气管扩张；③慢性支气管炎伴阻塞，其特征为用力呼气肺活量测定时有气道阻塞的表现；④慢性哮喘性支气管炎，其特征是患者有长期的咳嗽及咯痰史，后来肺部出现哮鸣者，因此与哮喘伴慢性气管阻塞的病人不同。
8.This company produces, the aviation obstruction light strictlyaccording to the international civil aviation organization (ICAO) thestandard appendix 14 volumes, the Federal Aviation Agency (FAA)requests and Chinese civil aviation profession standard MH/T6012-1999"Aviation Obstruction light" and so on the related standard developsthe production.
本公司所生产，航空障碍灯均严格按照国际民航组织（ICAO）标准附件十四卷、美国联邦航空局(FAA)要求及中国民用航空行业标准MH/T6012-1999《航空障碍灯》等有关标准而研制生产的。
9.Conclusion N-CTCP can accurately define the obstructive site in extrahepatic biliary obstruction. The specificity for the diagnosis of extrahepatic choledocholithiasis and malignant biliary obstruction is very high when combining with ASI.
结论 N -CTCP对肝外胆管梗阻定位准确 ,结合轴面源像 (ASI) ,对肝外胆管结石及恶性胆管梗阻的判断有较高的准确性。
10.Upper gastrointestinal series revealed several characteristic findings: dilatation of the stomach and the first and second portions of the duodenum, abrupt vertical compression of the third portion of the duodenum, churning without orderly peristalsis or passage of the contrast medium proximal to the obstruction, and relief of obstruction when the patient was placed in a position that diminished the drag of the mesentery.
做上消化道摄影检查，两列皆可见胃及十二指肠第一、二部分略显扩张，至第三部分则突然中断，显示有外在压迫痕迹，致钡剂流通受阻，同时有逆流的现象；但阻塞并非完全性，将病人变换姿势，受阻情形立见改善。
