The doctors'medical treatment in the medical service is not a private right, but a public power. It orignates from the patients'rights. The purpose is to sustain and enhance the patients' health, However, in our actual lives, the side effect of market - oriented economy brings out the power partly to deviate from the primary aim. This kind of phenomenon is called as alienation of doctor's power. The doctor's power of alienation infringes upon the rights of patients, causeing the conflicts between both sides and forms disputes of medical treatment. Only could the patients's rights and the doctors's duties be wholly defined by law, that the patients rights can be taken to restrict the doctors power, and the relationship between the two sides can be harmonious.

With specific physical characters,proton for postoperative breast cancer can improve dose homogeneity,lower dose to crucial organs such as the heart,lung and the opposite breast,and reduce the complications of normal tissues and incidence of the second primary tumor proton accelerated radiation for partial breast cancer can reduce therapy time,but its long time effect needs great patients and long time follow-up to beproved.

adult female Wistar rats undergone bilateral adrenelectomy were diveded to four groups:(A)simple bilateral adrenalectomy;(B)bilateral adrenalectomy with pieces of adrenal glands alloimplanted to the subrenal capsule (SRC);(C)the same with group B followed by institution of cyclosporing A(CsA) from the operative day to the 14th postoperative day;(D) group C plus ACTH given from 3rd to 31st postoperative day. Five months follow-up showed that all the grafts survived, regenerated and the serum corticosteron levels were in correspondence with histological features. This result showed SRC is an ideal site for adreal homotransplantation. Varying degrees of lymphocytyc infiltration were present in the implants in group B on the 2nd to 21st postoperative day, the fragment in groun C and D in which CsA was given did not show any lymphocytic infiltration, even after CsA was discussed. ACTH instituted in group D remarkably enhances the regenerative speed of the grafts After CsA and ACTH were stopped, no rejection episode appeared and the adrenal grafts survived well. The result has been similar to clinical homotransplantation of adrenal glands with vasculas anastomosis.The technigue is simple and the adrenal gland used for homotransplantation is easy to obtain.

AIM: Anterior cervical discectomy and Cage bone graft fusion followed by steel plate internal fixation can decompress the vertebral canal and then spinal cord in patients with multilevel cervical spondylotic myelopathy. Complete decompression is very important for such patients. This study is to investigate the effect of this technique on reconstruction of spinal function.METHODS:①Thirty-eight inpatients with multilevel cervical spondylotic myelopathy admitted to Department of Spine Surgery, Tianjin Hospital between April 2003 and February 2006 were involved in this study. The involved patients, 35 male and 3 female, were aged 43-72 years, with disease course of 0.5 to 5 years. Informed consents of therapeutic regimen were obtained from all the patients.②All the patients underwent anterior cervical discectomy and cage placement operation. The patients with destabilized combination underwent titanium-plate fixation, and those with stabilized combination underwent cage implantation alone. The cage used in the experiment was made of tetragonal polyether ether ketone (Intromed Company), and titatium-plate was Zephir plate (sofarmor Danek Company). The elastic modulus of tetragonal polyether ether ketone Cage was similar to bone tissue and could allow X-ray pass through, which was easy for postoperative fusion of implanted bone. The outer design of Cage bone graft with certain angle could allow cervical physiological antecurvature well recover; Surface radian was the same as end plate, and good fitness contributed to the good fusion rate of bone graft; The sawtooth antiskid design on the surface provided good stability immediately after implantation; Elastic modulus was between os integumentale and cancellous bone that made stress-shielding and subsidence of fusion cage reduced, and had good anticausticity and biocompatibility. ③ The clinical results were evaluated with Japanese Orthopaedic. Association (JOA) scoring system before, 2,8 and 24 weeks after operation: upper limb motor function (4 points), lower limb motor function (4 points), sensation (6 points) and bladder function (3 points). Higher scores indicated better function. Postoperatively, body examination and X-ray and MRI scanning of anteroposterior cervical vertebra were performed.RESULTS: Thirty-eight patients with multilevel cervical spondylotic myelopathy participated in the final analysis. Within postoperative several days, nervous symptoms improved obviously, muscle strength of lower limb was increased, limbs were more flexible after operation than before operation, and paresthesia of two upper limbs recovered in 38 patients. JOA was a score of (9.25±1.85) before operation, and it was (12.4±2.08) at postoperative 2 weeks, (13.2±2.07) at postoperative 8 weeks and (13.8±1.67) at postoperative 24 weeks.CONCLUSION: Multilevel discectomy and Cage implantation obviously improve sensorimotor function and lessen symptoms of patients with multilevel cervical spondylotic myelopathy.
