ABSTRACT
Fertility preservation technology provides an effective method of protecting fertility resources for young patients with malignant tumors, allowing them to offspring after their fertility is impaired. However, the development of this technology has caused many social and ethical controversies. From the perspective of ethics, this paper discussed the ethical issues faced by young female patients in the implementation of fertility preservation, including whether it is necessary to preserve fertility, the ownership of the preserved fertility resources and the fair and equitable distribution of health resources involved in its implementation process, and identifies these issues and controversies from ethical view. In order to eliminate public doubts and misunderstandings about the technology of fertility preservation, ethical principles of benefit and non-harm, informed consent, prudent application, and ethical supervision have to be followed in the process of providing fertility preservation services, so as to promote the further development and application of fertility preservation technology.
ABSTRACT
Objective To evaluate the clinical results of expansive cervical laminoplasty by anterior and posterior cervical decompression in the treatment of Cervical Spondylosis Myelopathy with developmental cervical stenosis.Methods Retrospective analyze 32 patients of cervical spondylosis myelopathy treated with expansive cervical laminoplasty by anterior and posterior cervical decompression from Mar 1995 to Aug 2000 years, there were 21 males and 11 females, developmental cervical stenosis (DCS) with cervical intervertebral disc protrusion in 25 cases, with the ossification of cervical posterior longitudinal ligament (OPLL) in 7 cases. Neural functionality (JOA Scoring System), cervical axial symptoms, and pre-and post-surgery dynamic cervical spine lateral x-ray films and cervical vertebra MRI were evaluated. Results 32 cases had been followed up for an average of 24.3 months, with an average age 58.9 years (range 38-72). The average rate of improvement of the third and sixth in month postoperative,the first and third postoperative year was 58.1%,65.9%,69.1% and 68.4% respectively;the excellent and good was 71.9%,81.3%,78.1%,77.3% respectivery. Cervical axial symptoms were reduced. Instability of the cervical spine were not found and decompression was confirmed on MRI. Conclusion Expansive cervical laminoplasty by anterior and posterior cervical decompression in the treatement of cervical spondylosis myelopathy with developmental cervical stenosis have good efficacy and it is a stable operative method.
