摘要:
肉牛前胃迟缓是由于前胃神经或肌肉组织出现功能性紊乱,造成前胃兴奋功能与收缩能力降低,从而导致瘤胃的消化能力下降,瘤胃内的食物不能够及时消化、排出,最终出现过量沉积,在腐解或者酵解后产生有毒物质,导致牛只胃部的微生物群遭到破坏,最终引发消化功能性障碍。患病后牛只的消化能力下降、机体紊乱,直接表现为采食量明显降低、产奶量降低等临床症状.

摘要:
游泳是一项人体在一定深度的水中,凭借肢体运动,利用水的浮力而进行的技能活动。它是古代人类在同大自然的斗争中,为生存而产生的,发展到现在,已成为受广大人民欢迎的有氧运动。游泳对身心健康能起到很好的作用:(1)可使心脏得到很好的锻炼,使心肌逐渐发达,收缩能力增强,更好地促进机体的新陈代谢。所以,游泳运动员的心脏跳动在平时比一般人慢而有力。一般人的脉搏,安静时为每分钟70-80次,而游泳运动员却为每分钟42-60次,个别甚至少到每分钟36次,这正是其心脏功能良好的具体体现。有的游泳运动员平时心跳只有每分钟40-50次,而跳动时排出的血量等于一般人每分钟70-80次心跳排出的血量。

摘要:
所谓“心衰”其实就是指心力衰竭。是指心脏这个中心泵的功能衰退,不能担当推动全身血液循环的重任了。中心泵怠工,全身血流积聚,各个脏器得不到有效的血液供应,轻者在运动时出现呼吸困难、乏力,并伴有下肢水肿等;重者哪怕静坐不动,也会喘息,不能平卧,出现肺淤血、消化道淤血等全身淤血的表现。一、患者出现心力衰竭的原因各类心脏病,都有可能会导致患者出现心力衰竭。因此我们将心力衰竭称为心脏疾病的最终阶段。患者如果具有冠心病,尤其是在出现心肌梗死之后,患者心脏的肌肉会遭受严重的损害,收缩能力会不断地下降,其往患者血管之中输送血液的能力会有所减弱,从而出现心力衰竭的症状。另外患者如果有高血压情况,如果没有好好地控制患者的血压,患者心脏的肌肉便会有所增厚,导致运动动能出现不协调情况,会影响患者输送血液的能力,而产生心衰问题。除此之外,其他的疾病,例如房颤、心肌炎、风湿性心脏病等,都会导致患者出现心力衰竭情况。

摘要:
心力衰竭是各种心脏疾病而引发的心功能不健全的一种疾病,心力衰竭最主要的就是因为心机功能的问题导致心肌的收缩能力下降,进而引发心脏的排血量不能满足机体生理需求。患有心肌衰竭的患者一般病情都是较为严重,治疗时间长,并且死亡率非常高。恰恰是因为这几点特征,所以心力衰竭的患者的观察非常重要,做好观察护理工作,这样才能减少病人的住院的时间,预防复发的可能。

摘要:
目的:探讨康复护理对产妇盆底肌肉收缩能力的影响.方法:将2018年2月至2019年8月收治的128例产妇按入院时间分为两组,各64例,对照组接受常规护理,研究组在常规护理基础上接受康复护理.分别在产后4周和产后8周评估两组产妇的盆底肌肉的收缩能力,并采用盆底功能障碍问卷(PFDI-20)评估产妇的生活质量.结果:两组产妇产后4周盆底肌肉的收缩能力无明显差异,而研究组产后8周盆底肌肉的收缩能力改善明显优于对照组,比较有统计学意义(P<0.05).研究组产后8周PFDI-20评分明显较产后4周降低,对照组无明显变化,研究组明显低于对照组(P<0.05).结论:完善产妇的康复护理措施,可有效改善其盆底肌肉的收缩能力,提高其生活质量.

摘要:
心力衰竭简称为心衰,是心内科常见疾病,是临床重症疾病,是各种心脏疾病的终末阶段,可诱发心肌舒张能力与收缩能力异常,无法将静脉回心血量充分排出,进而导致静脉血液淤积,动脉系统血液灌注不足,从而导致心脏循环障碍,此疾病可导致患者出现肢体乏力,呼吸不畅,液体潴留等症状。由于我国正处于老龄化,从而导致心衰患者呈递增模式,这不仅影响我国人民群众身心健康,更对患者的日常生活会产生一定影响,选择正确的治疗干预方案对疾病有着积极作用。临床中,针对心衰疾病多选择药物治疗,其中倍他乐克药物应用价值较高。因此,本文就针对倍他乐克在心衰疾病治疗的作用机制以及相关注意事宜开展讨论,一起和小编了解一下吧。

摘要:
目的:探讨硫化氢(H2S)对豚鼠左心室乳头肌组织电生理特性和收缩能力的影响.方法:以NaHS作为H2S供体;48只健康豚鼠,随机分成6组:正常对照组、NaHS 50 μmol/L组、NaHS 100μmol/L组、NaHS 200 μmol/L组、NaHS 100 μmol/L +Gli 20 μmol/L组、NaHS 100 μmol/L+BayK8644 0.5 μmol/L组,每组8只.制作豚鼠左心室乳头肌标本,用标准微电极细胞内记录技术,观测H2S对豚鼠左心室乳头肌组织电生理特性的影响,观测指标包括:静息电位(RP)、超射值(OS)、动作电位幅值(APA)、0相最大除极速率(Vmax)、复极20%、50%和90%时间(APD20、APD50 and APD90)及复极化平均速度;利用离体心脏组织灌流系统和张力换能器,观察H2S对左心室乳头肌收缩能力的影响,指标包括乳头肌收缩幅度(%)、主动张力上升最大速度(+ dT/dtmax,mg/s)及主动张力下降最大速度(-dT/dtmax,mg /s).结果:和正常对照组相比,用50、100、200 μmol/LNaHS均可使RP绝对值变大,A PD50、APD90缩短(P<0.05),复极化平均速度加快(P<0.05),乳头肌收缩能力降低;分别应用KATP通道阻断剂格列苯脲(Gli 20 μmol/L)和L-型钙通道开放剂Bay K8644(0.5 μmol/L)与H2S同时灌流,均可部分地阻断H2S对乳头肌细胞的生理效应.结论:H2S可影响左心室乳头肌电生理特性和收缩能力,这一作用的发挥是通过影响KATP通道和L-型钙通道来完成的.

摘要:
老王今年60岁了,老花眼10多年,平时需要戴老花镜。最近几天,突然不戴眼镜也能看清了,他觉得很开心。但是有人告诉他,这可能是某些疾病的前兆。他有些担心,所以前来咨询,老花眼突然能看清是好事吗?问:年轻时候近视,老年是否就不得老花眼了呢?答:我们的眼睛就像一个精密的照相机,能够调节焦点,有很好的看远、看近的调节功能。看远时,眼睛放松,睫状肌松弛,晶状体变薄,能够看远;看近时睫状肌用力收缩,晶状体变厚,能够看近。但随着年龄的增加,睫状肌的收缩能力下降,晶状体弹性减弱,导致调节力下降,从而出现老花眼。

摘要:
Background: Assessment of bladder outlet obstruction (BOO) and urethral stricture are standard clinical practice in patients with lower urinary tract symptoms (LUTS). This is currently achieved through pressure-flow studies. Research indicates that voiding function impairment of the bladder is associated with detrusor, lower urinary tract and nervous factors, it is not suit to release the fact just depended on the urine flow rate.rn Objective: To report a noninvasive technique and mathematic method of analysis for assessment of BOO in male subjects using noninvasive urodynamic(NUD)and to test the independent ability of noninvasive urodynamic data to evaluate the detrusor contractility.distinguish between voiding with and without abdomen force.classification of patients with and without obstructed using a nomogram similar to pressure—Qmax nomogram.rn Conclusion: Using noninvasive urodynamic data during voiding and a nomogram had independent discriminatory ability related to classification of detrusor contractility and outlet tract obstructed.
