过去,为了保证前段的血液供应,外直肌全麻痹的手术治疗要分2~3次完成,考虑到全麻痹的外直肌已无功能,我们提出在这种条件下可以不动含睫状前动脉的外直肌,只退后内直肌和将上,下直肌的外侧1/2移到外直肌的附着处,如此安排,可以一次手术完成治疗,这样可以缩短治疗时间,减少病人的痛苦和负担,我们治疗了7例8眼,结果比较满意。 相似文献

Summary To characterize and compare the pathologic, hemodynamic and electrocardiographic changes of both transeatheter laser and electrical
energy on ventricle, 33 subendocardial myocardium lesions were induced at energy 60, 120 and 240 Joules by either transcatheter
laser irradiation or electrical shock in 7 anesthetized dogs. The following results were observed: 1) Both laser and electrical
ablation on myocardium created nonhomogeneous myocardium injury, but laser ablation caused mainly focal tissue vaporization
and necrosis, while electrical shock induced widespread tissue degenerations; 2) Both laser and electrical induced-lesion
dimensions increased parallel to the total dosage of energy; 3) Laser ablation caused mainly (90%) single ventricular premature
beats and 86 % of them occurred within the first minute after energy discharged, while ventricular tachycardias were found
in any electrical energy groups; ventricular fibrillations occurring during laser and electrical ablation were 5 % and 13
% respectively (P< 0.01): 4) A decrease in aortic blood pressure and an increase in central verous pressure induced by laser ablation were
significantly less than that produced by the same amount of electrical energy (P<0.0l). Our preliminary results have shown that transeatheter laser ablation has great potential for becoming a practical
method in the management of refractory tachycardias. 相似文献

Preexpanded distant "super-thin" intercostal perforator flaps for facial reconstruction without the need for microsurgery. 总被引:1,自引:0,他引:1

BACKGROUND: Concept of the 'super-thin perforator flap' was introduced in 1994 by authors. Since then, various types of 'super-thin perforator flaps' were applied successfully especially for contour sensitive reconstruction such as face and neck. METHODS: Eleven patients requiring large flaps who presented with extensive disfiguring facial scar (male: seven cases, female: four cases). On the consideration of flaps' colour, texture and thickness requirements, the authors selected 'super-thin' anterior intercostal perforator flaps (AICP, range from 4 x 14 cm to 25 cm x 9 cm) for reconstruction purpose. First, tissue expanders (volume range from 800 cc to 1200 cc) were carefully inserted under the AICP. After the flaps were expanded for 2 months, distant scars were removed and the covering super-thinned flaps were transferred into recipient site. Two weeks later, pedicles in the anterior chest were cut down and flaps were transferred to replace all the left scars. RESULTS: Flap were survived without any complications. The colour, texture and thickness of the transferred flap were satisfactory, shrink of flaps were not observed after long term follow-up. The authors present a method of facial reconstruction that has the advantages of creating a large amount of thin tissue of both good colour and texture, without the need of microsurgery and few disadvantages of donor-site morbidity. The disadvantages are three-staged procedures, complications of tissue expansion and uncomfortable compulsory posture for patients. In our opinion, this is an alternative method of choice for reconstructing all large defects in the lower two-thirds of the face. 相似文献

We consider a class of Cohen–Grossberg neural networks with delays. We prove the existence and global asymptotic stability of an equilibrium point and estimate the region of existence. Furthermore, we show that the trajectories of the neural networks with positive initial data will stay in the positive region if the amplification function satisfies a divergent condition. We also establish the existence of a globally attracting compact set for more general networks. We estimate this compact set explicitly in terms of the network parameters from physiological and biological models. Our results can be applied to neural networks with a wide range of activation functions which are neither bounded nor globally Lipschitz continuous such as the Lotka–Volterra model. We also give some examples and simulations. 相似文献

Objective To evaluate the bioequivalence between recombinant human growth hormone (rhGH) for reconstitution, and two dosages of liquid formulation of rhGH [ (151U) 5mg or (301U) lOmg per 3ml ]. Methods The study drugs were tested in a randomized, single-blind and three-period crossover studies in 24 healthy male subjects. The three drugs were administered by subcutaneous injection at a dose of O. 21U/kg body weight. A continuous somatostatin infusion was given in order to suppress the secretion of endogenous GH. The ve- nous blood samples were drawn at different time points to test the serum concentration of GH. The pharmacokinetic parameters were analyzed by statistical methods. Results 90% confidence intervals (CI) of AUC0-24h among three products were all within 80% - 125% interval ( 103. 4% - 116. 5%, 105. 7% - 119. 6% and 91.9% - 103. 7%, respectively), and the Cls of C,~ among three products were all within 70% - 143% interval (91.9% - 114. 0%, 103. 7% -127. 2% and 81.6% -97. 4%, respectively). There was no statisitical difference of tmax among all the three products. Conclusion These data demonstrate that there is bioequivalence between rhGH for reconstitution and two liquid formulations of rhGH. 相似文献

克罗米芬兴奋试验预测卵巢储备功能的价值 总被引:1,自引:0,他引:1
目的探讨克罗米芬兴奋试验(CCT)在不孕妇女中预测卵巢储备功能的作用。方法对2001年1月至2005年2月就诊于广东省妇幼保健院的666例不孕症患者作为研究对象,分为A组(≥35岁)461例为高龄组,B组(〈35岁)205例为低龄组,另取156例年龄〈35岁、非女方不孕原因者作为对照组,对三组受试者进行CCT。结果CCT异常发生率A组、B组及对照组分别为27.76%、34.14%、2.56%,A组及B组与对照组比较差异均有非常显著性意义(P〈0.01)。基础卵泡刺激素(FSH)〈10IU/L、雌二醇(E2)〈180pmot/L的不孕患者CCT异常发生率分剐为17.46%、24.19%,均明显低于FSH≥10IU/L、E2≥180pmol/L患者的64.19%及39.4%(P〈0.01)。结论CCT预测卵巢储备功能较基础FSH更敏感,CCT可作为常规了解卵巢储备功能的一项检测方法。 相似文献

预测哪些人可能因急性发病而需要急诊入院,已成为英国国家医疗卫生服务体系(NHS)的一个重要话题。卫生部门将那些患有复杂的慢性疾病,经常不定期地去二级医疗机构就医的人们视为高危人群。确定这些人之后,社区护理员或其他卫生人员将通过“个案管理”的方法照顾他们。“个案管理”此前被定义为“对疾病尚未控制或所需费用昂贵的患者进行加强医疗计划”。社区护理人员可来自任何护理部门,但一般认为社区护士更能胜任这一角色。此方法能够减少可避免的急诊入院患者数量,并有助于实现到2008年3月减少5%急诊住院床位日的公共医疗服务目标。但是,如何才能界定需要急诊入院的高危人群呢? 相似文献
