脊柱侧凸矫形手术早期并发症的处理及预防 总被引:2,自引:2,他引:0
随着脊柱外科的迅速发展,国内越来越多的医院已经或正在开展各类脊柱侧凸的手术治疗。但由于脊柱作为人体的支柱,其解剖关系复杂,邻近有许多重要组织和器官,因此手术相关并发症并不少见,也不容忽视。如何预防和减少手术并发症,已经是迫在眉睫的任务,需要我们不断研究和深入探讨。根据发生时间可将手术并发症分为术中、术后早期及术后晚期并发症。现对脊柱侧凸矫形手术中及术后早期并发症的的处理及预防进行分析。 相似文献

一般性骨折愈合过程分为血肿机化演进期、原始骨痂形成期和骨痂改造塑形期;而骨质疏松性骨折愈合过程分为纤维骨痂期、软骨骨痂期和骨性骨痂期。骨质疏松性骨折愈合的组织学观察表明,纤维骨痂期主要是成纤维细胞合成Ⅲ型胶原;软骨骨痂期主要是成软骨细胞合成、分泌Ⅱ型胶原;骨性骨痂期主要是随着软骨内成骨的出现和发展,Ⅱ型胶原消失,逐渐由抗张力性能较强的Ⅰ型胶原所取代。一般来说,实验性骨质疏松性骨折的愈合方式与一般性骨折愈合方式相似,软骨内成骨和膜内成骨共同参与了骨质疏松性骨折的修复过程,但以软骨内成骨为主。 相似文献

Improved sexual behavior in male rats treated with a Chinese herbal extract: hormonal and neuronal implications 总被引:3,自引:0,他引:3

Aim: To investigate the influence of an extract obtained from five Chinese medicinal plants on sexual behavior of adult male rats. Methods: The extract was administered at doses of 30, 60 and 120 mg/kg by oral gavage, acutely (one time, 45 min before mating test) or subchronically (daily for 10 days) in sexually potent and sexually sluggish/impotent rats. Sexual behavior, serum levels of luteinizing hormone (LH) and testosterone (T) were evaluated in treated rats and compared with controls receiving vehicle. The effect of the extract on central dopaminergic neurotransmission was assessed in the nucleus accumbens using a microdialysis technique. Results: In sexually potent rats, both acute and subchronic treatment with the extract dosed at 30 and 60 mg/kg reduced mount latency and intromission latency. In sluggish/impotent rats, the acutely administered extract at the dose of 60 mg/kg shortened ejaculation latency, whereas subchronically administered at the doses of 30 and 60 mg/kg, reduced mount, intromission and ejaculation latencies, increasing also the percentage of mounting and ejaculating rats. The extract dosed at 60 mg/kg significantly increased LH and T following acute and subchronic administration and increased 3,4-dihydroxyphenylacetic acid levels in the nucleus accumbens, 30 min after the acute administration. Conclusion: The improvement in both appetitive and consummatory components of sexual behavior observed in male rats treated with the extract could be ascribed to increased serum T level in parallel with the activation of the central dopaminergic system. 相似文献

Aim: To investigate the effects of 17β-estradiol (E2), Peganum harmala extract (PHE) and caloric restriction (CR) on various testis parameters during aging. Methods: Twelve-month-old male rats were treated for 6 months with either E2 or PHE, or submitted to CR (40%). Results: Our results show that estrogens and CR are able to protect the male gonad by preventing the decrease of testosterone and E2 levels as well as the decrease of aromatase and estrogen receptor gene expressions. Indeed, E2, PHE and CR treatments induced an increase in the superoxide dismutase activities and decreased the activity of testicular enzymes: gamma-glutamyl transferase, alkaline phosphatase, lactate deshydrogenase as well as the aspartate and lactate transaminases in aged animals. In addition, the testicular catalase and gluthatione peroxidase activities were enhanced in E2, PHE and CR-treated rats compared to untreated animals at 18 months of age. Moreover, the positive effects of estradiol, PHE and CR were further supported by a lower level of lipid peroxidation. Recovery of spermatogenesis was recorded in treated rats. Conclusion: Besides a low caloric diet which is beneficial for spermatogenesis, a protective antioxydant role of estrogens is suggested. Estrogens delay testicular cell damage, which leads to functional senescence and, therefore, estrogens are helpful in protecting the reproductive functions from the adverse effects exerted by reactive oxygen species (ROS) produced in large quanti- ties in the aged testis. 相似文献

半月板组织工程的研究进展 总被引:1,自引:1,他引:0
半月板损伤临床常见,据美国矫形外科学会2008年的统计资料,美国每年全膝关节置换手术&gt;250000例,其中半月板损伤是骨性关节炎进展的关键因素。然而,半月板仅外周1/3有血液供应,发生于此部位的损伤采用缝合治疗可以愈合;而内侧缘2/3均为无血管区,损伤后自行愈合能力较差,目前临床上针对这类损伤多采用半月板部分切除或全部切除术。 相似文献
