狭窄

METHODS: In 10 open-chest anesthetized pigs, myocardial deformation was studied before and during dobutamine infusion, under control and ischemic conditions produced by various degrees of coronary artery constriction: 2 of nonflow-limiting stenoses of increasing severity reducing left anterior descending artery hyperemic flow by 40% and 70% and 2 flow-limiting stenoses reducing resting coronary flow by 25% and 50%.

10只麻醉开胸的猪以各种程度的冠脉压缩制作为缺血状态组或对照组，研究其多巴酚丁胺灌注前后心肌损伤情况。2只无血流限制狭窄猪模型予以渐增的左前降支血流充盈减少分别为40％和70％，2只血流受限狭窄猪模型减少剩余冠脉血流25％和50％。

Early pulmonary stenosis is a possible cause because when the stenosis develops early, the right ventricle does not develop, and the right heart becomes hypoplastic.

早期肺动脉瓣狭窄是一种可能的原因，因为假如狭窄出现的很早，右心室就不能发育，从而出现发育不全。

Lingual region stricture occurs in about 24% of patients with OSAHS, which may be caused by the incrassation of the retropharyngeal and lateral pharyngeal wall and fleshy tongue.

24%的OSAHS患者存在舌后区上呼吸道狭窄，除舌体肥厚外，咽侧壁和咽后壁的软组织增厚也是导致舌后区呼吸道狭窄的重要原因。

Solves this symptom method to divide into the surgery and the non-surgery treats, the non-surgery treats for example the physical property treatment and the pharmacological treatment, the effect is not often good, the surgery treats may divide into the traditional surgery and micro creates the surgery two kinds, the traditional surgery method is in the lumbar vertebra fusion the pexia, although this method excised has created the lumbar vertebra narrow yellow ligament and the small surface joint, but the surgery time was long, the wound was big as well as although the lumbar vertebra fusion and fixed has removed the pathological change stage abnormal movement, but the neighbor stage's abnormal movement increased, between the awl in plate's pressure elevated obviously, the small articular process exceptionally drew back changes with the fixed stage bone quantityThe loss, causes the fixed stage vertical motion stage to draw back changes ASD[1], but new micro creates the surgery is opens a small wound in the back, and implants the interspinal to open, then solution lumbar vertebra narrow sickness question.

解决此种症状的方法分为手术及非手术治疗，非手术治疗例如物理性治疗和药物治疗，往往效果不佳，手术治疗又可分为传统手术和微创手术二种，传统手术方法就是腰椎融合内固定术，虽然此种方法切除了造成腰椎狭窄的黄韧带和小面关节，但手术时间长，伤口大以及腰椎的融合和固定虽去除了病变节段的异常活动，但邻近节段的异常活动增加，锥间盘内的压力明显升高，小关节突的异常退变和固定节段的骨量丢失，导致固定节段上下运动节段的退变ASD[1]，而新型的微创手术是在背部开一个小伤口，并植入棘突间撑开器，进而解决腰椎狭窄症的问题。

Objective: To evaluate the technique and effectiveness of endoscopic treatment of laryngostenosis using CO_2 laser and give a clinical evaluation of CO_2 laser endoscopic bilateral posterior wedge-shaped cordectomy in patients with severely compromised airway due to bilateral paralysis of the vocal fold.

目的：通过对施行喉显微激光手术治疗的喉狭窄患者进行随访，探讨显微支撑喉镜下CO_2激光在喉狭窄治疗中应用的优势和不足，并评估CO_2激光双声带后份楔形切除术治疗双侧声带麻痹的临床应用价值。

The opening of leptomeningeal anastomoses vessel is the important way of collateral circulation in cases of serious stenosis or occlusion of MCA,the collateral flow between MCA and ACA is dominant. The RVACA/RVPCA can reflect the hemodynamic changes、the state of leptomeningeal anastomoses vessel when the MCA was serious stenosis or occlusion; There was a inverse correlation negative correlation between the RVACA/RVPCA and the NIHSS.

⑴在MCA中度以上狭窄或闭塞的情况下，皮质软脑膜吻合血管开放成为侧支循环的主要途径，以MCA-ACA之间的代偿为主；⑵RVACA和RVPCA在一定程度上可以反映MCA狭窄或闭塞时颅内血流动力学的改变、软脑膜侧支吻合的功能状况及有效程度；⑶RVACA和RVPCA与患者的NIHSS评分呈负相关，RVACA和RVPCA值越高的患者，其神经功能缺损程度越轻。

Age, gender, hypertension, high lipohemia had significant relationship with carotid artery stenosis.

颈动脉狭窄造成的眼部供血下降可以导致多种眼缺血性疾病，通过对颈动脉狭窄的正确诊断和治疗可以迅速缓解眼部的病情。

However , worse serious bronchial obstruction from severe bronchial malacia , mucosa congested edema and stenosis following heart transplantation with a high risk is rare .

原位心脏移植术后支气管软化塌陷狭窄的急诊支架置入治疗可改善支气管软化狭窄所致通气功能障碍，提高心脏移植成活率。

Flatten uroflow curves were seen in all patients with marked meatal stenosis. A bell-shaped flow curve was obtained in most patients after urethroplasty using oral mucosa graft combined with a local flap. The peak flow was within the normal range. The flow curve was obviously flat in patients with urethral stricture. The maximum flow rate was low and the voiding time prolonged apparently.

尿流率曲线低平的患者，均伴有明显的尿道外口狭窄；口腔粘膜片移植与局部皮瓣耦合再造尿道修复尿道下裂的患者，多数恢复了接近正常的钟形尿流率曲线，最大尿流率在正常范围：尿道下裂术后尿道狭窄的患者排尿曲线明显低平，最大尿流率降低，排尿时间延长。

We concluded that uroflowmetry was a simple, non-invasive procedure which provided an objective evaluation of the uroflow in hypospadias. Urethral stricture after urethroplasty could be diagnosed with uroflowmetry. The low flow rate in congenital hypospadias was mainly due to meatal stenosis. Oral mucosa graft combined with a local flap for hypospadias repair provided satisfactory functional results.

我们推论：尿流率测定评价尿道下裂患者排尿功能，方法简便，准确可靠，对尿道下裂术后尿道狭窄具有诊断意义；先天性尿道下裂患者尿流率曲线多数呈平台形，最大尿流率降低，其主要原因为尿道外口狭窄；口腔粘膜片移植与局部皮瓣耦合组建尿道修复尿道下裂功能性效果良好。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
