谈到头颈部疾病的影像学检查,人们首先想到的是CT和MRI,但是随着技术和仪器的进步,超声在头颈部疾病诊断中的作用日益增强。上世纪中、下叶超声开始应用头颈部疾病的诊断,随后新的技术手段层出不穷,细微分辨力逐步提高,例如超声可以清楚显示甲状腺腺体内0.1cm的病变,远远超过了CT和MRI的分辨力。因此,超声逐渐成为头颈部疾病最重要的成像技术,甚至占据了不可或缺的地位。

目的:探讨冷冻球囊消融术治疗房颤的安全性和有效性。方法:房颤患者91例,23例采用冷冻球囊消融术治疗(球囊组),68例采用药物治疗(药物组)。以手术中肺静脉与心房电隔离(PVI)终止房颤发作为急性治疗成功指标,以出院后12个月是否复发评价... 详细信息

目的:探讨冷冻球囊消融术治疗房颤的安全性和有效性。方法:房颤患者91例,23例采用冷冻球囊消融术治疗(球囊组),68例采用药物治疗(药物组)。以手术中肺静脉与心房电隔离(PVI)终止房颤发作为急性治疗成功指标,以出院后12个月是否复发评价远期治疗成功率,同时比较两组治疗的安全性。结果:球囊组患者中,经冷冻消融,98.8%的肺静脉实现PVI,手术均终止房颤发作。出院后12个月,冷冻球囊组治疗成功率为66.7%(14/21,2例失访),药物组治疗成功率为35.3%(24/68),两组比较差异有统计学意义(χ~2=6.455,P<0.01)。同时球囊组患者症状明显减轻,生活质量提高。安全性方面,球囊组也优于药物治疗组。结论:应用冷冻球囊消融技术治疗房颤的有效性和安全性均优于传统药物治疗,为房颤的治疗提供了新思路。

Titanium based iro2 +Ta2O5 oxide anodes with.different compositions and pyrolysis temperatures were prepared by termodecompoisition meth.d. By using X-ray diffraction (XRD), th. structure and texture coefficient of th. coatings, TC(h.l), of iro2 rutile crystal h.ve been tested.

Th. crystallite size of th. mixed oxide coatings were finest for th. th. film of 70%iro2 +30%Ta2O5,and decreased with.th. pyrolysis tempemture.

Service life of two different oxide anodes in ph.nolsulfonic acid (PSA) solution was investigated by accelerated electrolysis. Th. durability of Ti/iro_2+Ta_2 O_5 anode increased by th. addition of SnO_2 in th. mixed oxides. Th. degradation mech.nisms of Ti/iro_2+ Ta_2 O_5 and Ti/iro_2 +Ta_2 O_5 +SnO+2 anodes were different. It was sh.wn from th. observation of scanning electron microscopy (SEM) and th. electroch.mical measurement th.t, th. deactivation of Ti/iro_2 + Ta_2 O_5 anode was due to th. build-up of an organic film on surface. Th. growth.of th. covered film on surface was restricted by addition of SnO_2, wh.ch.resulted in increasing of th. service life of anodes. Th. over-potential for oxygen evolution on Ti/iro_2 +Ta_2 O_5 electrode increased after doping SnO_2, and th. intermediate products of PSA building-up on th. surface was much.more rapidly oxidized. Meanwh.le, a certain part of th. surface oxide deposit entered into th. solution leading to loss of oxides, wh.ch.resulted in degradation of Ti/iroO_2 + Ta_2 O_5 anode containing SnO_2 component.
