Objective To probe into the perioperative nursing method during osterior fusion and fmation for idiopathic scoliosis. Methods The study involved 31 patients with idiopathic scoliosis treated with posterior correction nails and selective spinal fusion with hook-rod system fixation.The severe patients were treated with extensive posterior release or anterior correction and fusion posterior to release.Before the operation,the patients were administrated with mental nursing,lung function exercise,self-elongation exercise,wake-up pilot training,self-image appraisement and bed and life skills exercise.After the operation,an observation was done on the change of nervous system,propor turning the body over best clinostatism,drainage tube care,respiratory passage care,functional exercise instruction and discharge instruction. Results The operation was accomplished successfully in all the patients,which showed that the body height was increased 2-15 cm.There found no complications including loosening or breakage of the nails or sticks,nervous system injury,incisional wound infection or press~e sore. Conclusion Preoperative sufficient preparation and fine postoperative nursing are important guarantee to successful operation and fast rehabilitation.

Intravenous glucose tolerance test(IVGTT)and oral glucose-insulin releasing test(OGIRT) in 12 subjects with normal glucose tolerance were performed.The results showed that the peak of insulin secretion Was at 40 minutes during()GIRT.The ratio of the change of insulin-to-glucose at 40 minutes(△I40/△G40)is an index in reflecting insulin sensitivity and β-cell function.

ObjectiveTo investigate the clinic and pathologic features of one patient diagnosed with neurocutaneous melanosis ( NCM ) by biopsy.MethodsA 21-year-old woman presented with a 2-month history of tinnitus,headache,vomiting and 1-month history of impaired vision.At birth,a massive nevus covering most of the posterior abdomen had been noted as well as the presence of multiple smaller lesions all over the body.Magnetic resonance imaging demonstrated a posterior fossa cyst compatible with the Dandy-Walker syndrome and extensive leptomeningeal enhancement. Surgery was performed to cystectomy and to obtain pathologic specimens from the leptomeninges. Biopsy and immunohistochemical study was performed.ResultsAt surgery,diffuse black pigmentation of the leptomeninges and the cyst was found.Under microscope,the cyst and leptomeninges were composed with melanocytes with variable pigmentation.Those cells positive for HMB45,MelanA,S100 and vimentin.Ki-67 positive cells ＜ 1％.The pathologic diagnosis wasleptomeningeal diffusemelanocytosis. Thepatientdied 2months after thesurgery.ConclusionsNCM is characterized by a focal or diffuse proliferation of melanin-producing cells in both the skin and the leptomeninges.NCM could be compatible with the Dandy-Walker syndrome.Definite diagnosis relies upon the histological data obtained by mean of biopsy.
