夏天涮火锅时注意啥

<正>吃起来酣畅淋漓的火锅,似乎一年四季都是饭桌上的宠儿。不过如果夏天吃火锅,既想大快朵颐,又要吃得健康,就有几点需要特别注意。首选酸汤或清汤在炎热的夏天,酸汤能开胃清火,去腻除燥,消暑健体。此外,夏季人体出汗多,易损失水分,酸汤火锅的酸味能敛汗祛湿。除了酸汤,清汤也是不错的选择。     

人生需要淡定

面对人生的起起落落,我们既要有对美好生活的追求和向往,更要有一种淡定的生活态度。人生需要淡定,淡定需要勇气。淡定不是平庸,而是一种超然的生活态度。淡定的人,懂得善待生命,沉稳而不缺少热情。淡定的人,不计较日常琐事,不因生活的压力而焦虑,总能微笑着面对困难、面对环境。淡定的人,存挫折面前会告诫自己要重新振作,适应新的处境;在苦难面前,会命令自己跨过颓唐,去拥抱新的一天。     

怎样防止春季脱发

进入春季以后,有些人会发现自己的头发掉得厉害,这可能是一种季节性脱发,主要是由于春天气候干燥造成的。只要在日常生活中多加注意,春季脱发是可以预防的。首先,生活要有规律。要保证睡眠时间,注意劳逸结合,不要太疲劳、太紧张。其次,饮食要多样化。多吃水果和     

德行,灵魂的力量

人在没有监督和约束的情况下,靠什么自守?靠德行。德行是人之灵魂的反映,对人的言行起着主导性、决定性的作用。德行具有极大的力量。宋代胡宏在《胡子之言·文王》中曰:有源之水,寒冽不冻;有德之人,厄穷不塞。意思是说:有源的水,即使在寒冷的天气里,也不会冻结成冰;有美德的人,即使身处困穷之境,也不会失意潦倒。过去,我们相信知识就是力量;当今,在讲诚信的社会里,我们更要相信德行就是力量。我们如果不能在灵魂的坝坎上修筑一条柔性的道德防线,就很     

秋季锻炼要防止拉伤

秋季气候多变,早晚和午间温差较大,空气比较干燥。在秋季进行体育锻炼尤其要注意防止拉伤和秋燥。对于任何一项运动来说,准备活动都是必须的,在任何季节也都是应该注意的。但是,在秋季气温较低的情况下,人的肌肉和韧带会反射性地引起血管收缩和粘滞性增加,关节的活动幅度减小,韧带的伸展度降低,神经系统对肌肉的指挥能力在没有准备活动的情况下也会下降,因此,在锻炼前如果不做充分的准备活动,就可能会发生关节韧带拉伤、肌肉拉伤等,从而影响工作和生活。因此,在秋季进行体育锻炼尤其是晨练前一定要充分做好准备活动。另外,还要注意运动量应由小到大,循序渐进。运动量应以锻炼时自觉身体有些发热并微微出汗、锻炼后感到轻松舒适为宜,这样也能有效防止肌肉拉伤。     

面对疫情如何调节紧张情绪

新春伊始,突如其来的新型冠状病毒肺炎疫情牵动人们的心。随着疫情蔓延加重,一些老年人的神经变得更加敏感,对一时没有控制的疫情不免担忧恐慌。笔者为此提醒中老年朋友,面对疫情应善于调节紧张情绪。紧张情绪的表现明显情绪反应。当老年人听说疫情来了,或身边发现疑似病例时,焦虑感陡然而生,呼吸急促,表现出不安、害怕、恐慌。     

秋季抑郁莫忽视

我国传统医学认为,秋应于肺,在志为忧,如再遇上不称心的事,极易导致心情抑郁。抑郁症是现代紧张病的代表性疾病,其主要症状包括失眠、疲倦、身体不适、头痛、食欲不振等。临床症状轻微者,只要适当自我放松,舒解压力,还不致妨碍工作,但病情严重的,会出现头痛、肚痛、恶心或晕倒。因此,秋季宜防抑郁症。有人曾经做过研究,人在心情愉快的时候,体内一些有益激素、酶和乙酰胆碱会增加分泌,使血液的流量、神经细胞的兴奋被调节到最佳状态,有利于身心健康。相反,如果终日郁     

老人睡眠有十忌

忌睡前吃东西人进入睡眠状态后,机体部分活动节奏便放慢,并进入休息状态。如果临睡前吃东西,肠胃等又要忙碌起来,身体其他部分也无法得到良好休息,不但影响入睡,而且还有损健康。忌睡前用脑过度如有晚上工作和学习的习惯,则要把较伤脑筋的事先做完,临睡前则做些较轻松的事,使脑子放松,这样更容易入睡。否则,大脑处于兴奋状态,即便躺在床上也难以入睡,时间长了,还容易失眠。忌睡前情绪激动人的喜怒哀乐都容易引起神经中枢的兴奋或紊乱,使人难以入睡,甚至造成失眠。因此,睡前要尽量避免大喜大怒或忧思恼怒。忌睡前饮浓茶、喝咖啡浓茶、咖啡属刺激性饮料,含有能使人的精神处于亢奋状态的咖啡因等物质,睡前喝了易造成入睡困难。     

智慧人生要有点小爱好

有人说,人生成功的关键在于一定要有明确的目标。对此,我很认同。有目标就有方向,有目标就有动力。大目标产生大动力,催生大成功。因此,成功的人生不能没有目标,否则,就好比在黑暗中远行,方向不明,就往往会一事无成。但是,成功的人生不一定是健康的人生、智慧的人生,健康、智慧的人生需要有点小爱好。这就好比红花有了绿叶衬,才更显得更加艳丽多彩一样。也许你现在还年轻,认为只要有了目标,就会有追求与快乐,并不太在

Femoral-to-port through-and-through wire access to reestablish subcutaneous port function

OBJECTIVE: Central venous catheter malfunction often results from fibrin sheath formation and is routinely addressed with thrombolytic therapy or mechanical stripping. Mechanical stripping from a distant access site such as a femoral vein is the only option for a subcutaneous port that has failed thrombolytic therapy. When a fibrin sheath has rendered the catheter tip inaccessible to snaring, catheter salvage cannot be achieved, requiring port exchange. We report two cases in which an inaccessible catheter tip was mobilized via advancing a wire through the port and through the catheter, allowing for successful snaring, mechanical stripping, and return of normal port function. CONCLUSION: Passage of a hydrophilic wire through a subcutaneous port and beyond the catheter tip is technically possible. The wire can be snared from a femoral access to achieve successful catheter stripping when direct catheter snaring is not possible.     

A modified procedure for percutaneous abscess and fluid drainage using the Malecot catheter-Stamey needle technique

Percutaneous abscess and fluid drainage (PAFD) of various intraabdominal collections with computed tomographic and ultrasonic guidance is well established. Current techniques use a catheter of pigtail design introduced either by multiple step dilatations or a separate trocar insertion, and are subject to complications which can be avoided by use of a new catheter-needle system we propose. This system uses a straight, winged, Malecot catheter which is introduced in one step with a Stamey needle. We report upon our experience with the Malecot catheter/Stamey needle system for PAFD in 13 patients with good results. This method ensures a single step introduction of a large bore catheter, accurate catheter placement, a stable catheter position with good function, and easy drainage of multiloculated or multiple abscesses.     

Laser catheter thermal angioplasty: technique and early results in 34 patients

The laser catheter is a nylon vascular catheter with a metal tip that has an end hole as well as side holes. The metal tip is heated by laser energy delivered through an optical fiber embedded in the catheter wall. The catheter may be advanced over a guidewire for use as an adjunct to balloon angioplasty or for use in smaller vessels as the exclusive method of recanalization. We used the catheter to treat 34 patients with 54 discrete vascular lesions in 35 extremities. Twenty patients were treated for clinically significant claudication and 14 for ischemic changes. Laser catheter-assisted balloon angioplasty was used to treat six iliac artery occlusions, two iliac artery stenoses, 10 superficial femoral artery occlusions, 12 superficial femoral stenoses, four popliteal artery occlusions, and three popliteal stenoses. Initial technical and clinical success in these patients, with follow-up periods of 3-6 months, was equivalent to the results of previous reports of laser probe-assisted balloon angioplasty. In 11 patients, 15 of 17 popliteal or tibial-peroneal lesions were treated with the laser catheter without subsequent balloon angioplasty. The treatment was successful in eight of these patients, with follow-ups for up to 6 months. Our results suggest that the laser catheter is a useful device for the treatment of vascular stenosis or occlusion when used either as an adjunct to balloon angioplasty or in smaller vessels as the exclusive method for angioplasty.     

Semiquantitative fast flow velocity measurements using catheter coils with a limited sensitivity profile.

Flow measurements can be used to quantify blood flow during MR-guided intravascular interventional procedures. In this study, a fast flow measurement technique is proposed that quantifies flow velocities in the vicinity of a small RF coil attached to an intravascular catheter. Since the small RF coil receives signal from only a limited volume around the catheter, a spatially nonselective signal reception is employed. To enhance signal from flowing blood, and suppress unwanted signal contributions from static material, a slice-selective RF excitation is used. At a velocity sensitivity of 150 cm/s, a temporal resolution of 2 x TR = 10.2 ms can be achieved. The flow measurement is combined with an automatic slice positioning to facilitate measurements during interventional procedures. The influence of the catheter position in the blood vessel on the velocity measurement was analyzed in simulations. For blood vessels with laminar flow, the simulation showed a systematic deviation between catheter measurement and true flow between -15% and 80%. In four animal experiments, the catheter velocity measurement was compared with results from a conventional ECG-triggered 2D phase-contrast (PC) technique. The shapes of the velocity time curves in the abdominal aorta were nearly identical to the conventional measurements. A relative scaling factor of 0.69-1.19 was found between the catheter velocity measurement and the reference measurement, which could be partly explained by the simulation results.     

Development of a New Coaxial Balloon Catheter System for Balloon-Occluded Retrograde Transvenous Obliteration (B-RTO)

Purpose To develop a new coaxial balloon catheter system and evaluate its clinical feasibility for balloon-occluded retrograde transvenous obliteration (B-RTO). Methods A coaxial balloon catheter system was constructed with 9 Fr guiding balloon catheter and 5 Fr balloon catheter. A 5 Fr catheter has a high flexibility and can be coaxially inserted into the guiding catheter in advance. The catheter balloons are made of natural rubber and can be inflated to 2 cm (guiding) and 1 cm (5 Fr) maximum diameter. Between July 2003 and April 2005, 8 consecutive patients (6 men, 2 women; age range 33–72 years, mean age 55.5 years) underwent B-RTO using the balloon catheter system. Five percent ethanolamine oleate iopamidol (EOI) was used as sclerosing agent. The procedures, including maneuverability of the catheter, amount of injected sclerosing agent, necessity for coil embolization of collateral draining veins, and initial clinical results, were evaluated retrospectively. The occlusion rate was assessed by postcontrast CT within 2 weeks after B-RTO. Results The balloon catheter could be advanced into the proximal potion of the gastrorenal shunt beyond the collateral draining vein in all cases. The amount of injected EOI ranged from 3 to 34 ml. Coil embolization of the collateral draining vein was required in 2 cases. Complete obliteration of gastric varices on initial follow-up CT was obtained in 7 cases. The remaining case required re-treatment that resulted in complete obstruction of the varices after the second B-RTO. No procedure-related complications were observed. Conclusion B-RTO using the new coaxial balloon catheter is feasible. Gastric varices can be treated more simply by using this catheter system.     

Transbrachial approach for aortic and selective supraaortic vessel catheterization using a safe and easy technique to reform the Simmons II catheter tip.

A total of 286 patients (158 outpatients) were examined by intra-arterial DSA in the evaluation of cerebrovascular disease using a transbrachial approach. In all cases a 5F introducer sheath, a 5F pigtail catheter for aortic arch injection and a 5F Simmons II catheter for selective catheterization were used. Excellent demonstration of aortic arch and supraaortic arteries (including intracranial circulation) was obtained (92.2-100%). The complication rate was favorable, with only one major complication (thrombosis of an axillary artery). The use of an introducer sheath minimizes local complications and vessel wall damage during catheter exchange. Aortic arch injection must always be performed prior to selective catheterization. The results of selective catheterization prove the suitability of the Simmons II catheter, whose typical shape was easily and safely obtained using the configuration of the pigtail catheter and a 180 cm long guide wire for catheter exchange. Using the technique as described, the transbrachial approach is a safe and easy way for optimal vascular evaluation in cerebrovascular disease, especially useful in outpatients.     

Management of visceral interventional radiology catheters: a troubleshooting guide for interventional radiologists.

Visceral interventional radiology catheters can be difficult to exchange or remove for a variety of reasons. These reasons include exit of the guide wire through the side holes of the catheter, blockage of the catheter, difficulty unlocking the pigtail, retention of the string after catheter removal, migration of the string ahead of the guide wire, catheter fracture, and snaring of an adjacent stent by the pigtail. Secure fixation of the catheter to the skin is important. A technique that allows secure fixation without direct puncture and suturing of the catheter to the skin is recommended. If a catheter falls out or is inadvertently removed, access can occasionally be regained and the catheter can be replaced without repuncture. The timing of catheter removal is based on the clinical condition of the patient and the daily output from the catheter. "Tractography" is a useful study before removal of any catheter that requires a mature tract for removal, particularly cholecystostomy catheters and transpleural catheters. In biliary catheter exchange, the most vital issue is the position of the side holes of the catheter. If an abscess cavity remains large after catheter drainage, the catheter can be repositioned or a second catheter can be placed.     

Radiological Interventions for Correction of Central Venous Port Catheter Migrations

The purpose of the study is to evaluate radiological–interventional central venous port catheter corrections in migrated/malpositioned catheter tips. Thirty patients with migrated/malpositioned port catheter tips were included in this retrospective analysis. To visualize the catheter patency, a contrast-enhanced port catheter series was performed, followed by transfemoral port catheter correction with various 5F angiographic catheters (pigtail, Sos Omni), goose-neck snare, or combinations thereof. One patient showed spontaneous reposition of the catheter tip. In 27 of 29 patients (93%), radiological–interventional port catheter correction was successful. In two patients, port catheter malposition correction was not possible because of the inability to catch either the catheter tip or the catheter in its course, possibly due to fibrin sheath formation with attachment of the catheter to the vessel wall. No disconnection or port catheter dysfunction was observed after correction. In migrated catheter tips, radiological–interventional port catheter correction is a minimally invasive alternative to port extraction and reimplantation. In patients with a fibrin sheath and/or thrombosis, port catheter correction is often more challenging.     

Cerebral damage following ventricular shunt for infantile hydrocephalus evaluated by computed tomography

Summary The results of a late CT control of infantile hydrocephalus is reported with an analysis of effects of the catheter on the cerebral tissue in the immediate and late postoperative course. The most frequent finding is blood in the ventricle and/or subependymal or intraparenchymal along the catheter or near its tip.     

Vessel bifurcation localization based on intraoperative three-dimensional ultrasound and catheter path for image-guided catheter intervention of oral cancers

We present a method to localize intraoperative target vessel bifurcations under bones for ultrasound (US) image-guided catheter interventions. A catheter path is recorded to acquire skeletons for the target vessel bifurcations that cannot be imaged by intraoperative US. The catheter path is combined with the centerlines of the three-dimensional (3D) US image to construct a preliminary skeleton. Based on the preliminary skeleton, the orientations of target vessels are determined by registration with the preoperative image and the bifurcations were localized by computing the vessel length. An accurate intraoperative vessel skeleton is obtained for correcting the preoperative image to compensate for vessel deformation. A reality check of the proposed method was performed in a phantom experiment. Reasonable results were obtained. The in vivo experiment verified the clinical workflow of the proposed method in an in vivo environment. The accuracy of the centerline length of the vessel for localizing the target artery bifurcation was 2.4 mm. These results suggest that the proposed method can allow the catheter tip to stop at the target artery bifurcations and enter into the target arteries. This method can be applied for virtual reality-enhanced image-guided catheter intervention of oral cancers.
