Objective To investigate the expression of nicotinic acetylcholine receptor (nAchR) subunits, and the effects of smoking on its expression in peripheral blood mononuclear cells (PBMCs). Methods Blood was collected from 92 healthy male smokers and 36 healthy male non-smokers. Peripheral blood monocytic cells were obtained, and reverse transcription-polymerase chain reaction (RT-PCR) was employed to study the gene expression of 11 nAchR subunits (?2-?7, ?9, ?10, ?2-?4). Results The results showed that the PBMCs of smokers and non-smokers appeared to express ?2, ?5, ?6 and ?7 only out of 11 nAchR subunits. However, the expression of ?5 and ?7 subunits was lower in smokers′ PBMCs than in non-smokers′ (P

Objective To observe the anatomic landmarks in the thoracic cavity under thoracoscope in procedures for scoliosis,so as to facilitate the intraoperative localization and the prevention of complications. Methods During 23 cases of thoracoscopic anterior procedure,anatomic landmarks,including the segmental vessels,azygous vein,intervertebral discs,rib heads and great splanchnic nerve,were observed. Results The segmental vessels of T 6～10 were situated at the center of the vertebral body and their position was relatively constant.The T 7～10 intervertebral discs were a little bit prominent and white-colored,which were easily distinguished.The rib heads corresponding to their vertebral bodies were good landmarks.The great splanchnic nerve crossed over the T 7～9 vertebral bodies arrisways. Conclusions With the assistance of anatomic landmarks,accurate localization of the vertebral body is possible,which is helpful to the prevention of spinal cord injury and the decrease of frequency of radiation exposure.

[Objective] To evaluate the surgical techniques and its clinical results of CDH Legacy in the treatment of scoliosis.[Method]Nine patients(7 female and 2 male)with scoliosis instrumented with posterior CDH Legacy system were recruited for this retrospective study.The etiological classification of scoliosis were idiopathic for 7,congenital for 1,neurofibromatosis(NFl)for 1.The average age was 13.5 years(ranged 11～18 years).The average preoperative Cobb's angle was 54?(ranged 48?～68?).Seven AIS and one CS patients received one stage posterior CDH Legacy instrumentation;the NFl patients received one stage anterior epiphysiodesis and second stage posterior CDH Legacy instrumentation.[Result]There was no death,no infection and no neurological complication.No intra-operative fracture,no dura matter or pleuml laceration occurred.Superior Mesenteric Artery Syndrome occurred in one patients and recovered with conservative treatment.Posterior Cobb's angle averaged 20? with correction rate of 63%.The duration of follow-up averaged 23 months(ranged 20～30 months).Surgical time averaged 260 min(ranged 210～300 min)and mean EBL was 700 ml(300～1 000 ml).Bony fusions were achieved in all patients and no coronal or sagittal plane decompensation occurred.The loss of correction at last follow-up was 4? with 7.4% loss of correction rate.[Conclusion]The clinical results of CDH Legacy are as good as the other three generation implants,its advantage lies in lower profile,solid inter-locking,versatile implants and handy manipulation.

[Objective]To evaluate diagnostic and the therapeutic options of osteoid osteoma of the spine associated with scoliosis. [Methods]Nine patients with osteoid osteoma of the spine were treated from 1997 to 2006.All patients presented with spine deformity as their main complaint at the first consultation.The mean age was 15.2 years (range 8-21 years).Two patients had their osteoid osteoma in the thoracic area,2 in the thorcolumbar area ,and 5 in the lumbar area.Three were well controlled after long term administration of nonsteroidal anti-inflammatory drugs,and the other 6 were treated with en bloc excision.[Results]All the 6 patients with en bloc excision of the tumor were pain-free post-operatively.The scoliotic curve disappeared or was less than 15 degrees in 5,but the structural curve persisted in 4.[Conclusion]The spinal osteoid osteoma should be suspected when back pain or painful scoliosis occurs in adolescents.Computed tomography is necessary to evaluate the location and features of the lesion.En bloc excision of the tumor can be suggested if the symptoms are not well relieved with nonsteroidal anti-inflammatory drugs.

Objective To evaluate the clinical manifestation and the treatment strategy of the scoliosis associated with Chiari malformation and /or syringomyelia. Methods Fifty-two cases suffered from scoliosis with Chiari malformation and /or syringomyelia were divided into three groups for surgical treatment: 1) Group 1: 18 cases had scoliosis with Chiari Ⅰmalformation and /or syringomyelia without obvious neurologic impairment, their scoliosis was corrected with posterior instrumentation, but their Chiari Ⅰmalformation and syringomyelia were left untreated surgically. 2) Group 2: 12 patients, whose scoliosis was not indicated for surgery but those Chiari malformation associated with syringomyelia, underwent posterior sub-occipital craniectomy to enlarge foramen occipital magnum, C1 posterior arch decompression, duraplasty and syrinx-subarachnoid space shunting no matter whether neurologic deficits were present or not. 3) Group 3: 22 cases in addition of correction of scoliosis, due to neurologic deficits caused by Chiari Ⅰmalformation or syringomyelia, two-stage surgery was indicated: firstly, with posterior suboccipital craniectomy to enlarge foramen occipital magnum, C1 posterior arch decompression, duraplasty and syrinx-subarachnoid space shunting 6 months later, then underwent the scoliosis correction with instrumentation. Results In 34 patients who underwent craniovertebral decompression, only 6 of the 24 cases with preoperatively neurologic deficits achieved mild improvement within 6 months postoperatively. In 40 patients who were treated with posterior correction for scoliosis, the average frontal correction was 63% and the average sagittal correction was 80% for scoliosis less than 90?, the average frontal correction was 49% and the average sagittal correction was 74% for scoliosis more than 90?. At a follow-up of 6 months to 5 years, the average loss of the frontal correction was 6%. Conclusion Scoliosis associated with Chiari malformation and /or syringomyelia can be effectively treated with the similar results, as for adolescent idiopathic scoliosis. The mainstay for diagnosis is MR imaging. Accurate diagnosis and proper treatment for Chiari malformation or syringomyelia before scoliosis surgery will improve the rate of scoliosis correction, decrease the neurological complications.

Objective To evaluate the biomechanical basis and long term clinical outcome of the offset hook-screw combined instrumentation in preventing against correction loss after it is used to treat the unstable thoracolumbar fractures. Methods Of 98 cases treated with the offset hook-screw combined instrumentation from July 1997 to December 2002, 64 with follow-up over two years were reviewed. All 64 cases received operation within average 3.2 days after injury, of which 41 were fixated with CD or CD-Horizon instrumentation and 23 with TSRH instrumentation. The long term clinical outcome evaluation included the maintenance of the vertebral height restoration, the sagittal kyphotic Cobb angle loss and the coronal Cobb angle correction loss. Results No death occurred. But after operation, there was one case with worsened neurological deficits (recovered one week after surgery) and two with deep infection. The average post-operative vertebral height and the coronal Cobb angle were restored by 89.0% and 100.0% respectively and the sagittal kyphotic Cobb angle corrected from preoperative 31?to postoperative -1? . During the follow-up for 24-62 months, no instrumentation breakage occurred. The pseudoarthrosis was affirmed in one case and suspected in two with the vertebral height loss of 8.6% and the kyphotic Cobb angle correction loss of 4?respectively. Conclusions The offset hook-screw combined instrumentation can satisfactorily restore the normal sagittal profile, effectively prevent the fixation loosening or breakage, minimize the mechanical failure of instrumentation, and particularly reduce the loss of long-term correction.
