Objective To express human chemokine-like factor 1 (CKLF1) in Drosophila S2 cells and study its function. Methods The pMT/V5-His-CKLF1 expression plasmid was constructed and transfected into Drosophila S2 cells. The positive clones were selected through PCR and RT-PCR. The culture medium was analyzed by Western blot with anti-CKLF1 polyclonal antibody. Chemotaxis and MTT assays on human peripheral blood and C2C12 cells, respectively, were then carried out with the medium. Results CKLF1 was transcribed efficiently in S2 cells. The expressed CKLF1 protein could be detected in the culture supernatant by Western blot, which showed weak chemotactic activity on both human peripheral blood neutrophils and lymphocytes as well as enhancing effect on the proliferation of C2C12 cells. Conclusion CKLF1 was expressed successfully in Drosophila S2 cells and secreted into the culture medium. The recombinant CKLF1 expressed in Drosophila cells can chemoattract leucocytes and promote the proliferation of C2C12 cells.

Objective To evaluate the clinical outcomes of modified eggshell technique through posterior approach for the treatment of hard thoracic disc herniation. Methods From January 2006 to June 2009, 22 patients admitted for hard thoracic disc herniation were reviewed, including 13 males and 9 females, with an average age of 49.5 years (range, 33-69). The courses of disease were 11 months on the average (range, 3-18 ). The lesions located in T8-9 for 4 cases, T9-10 for 9, T10-11 for 7, T11-12 for 2. Each of the patients underwent X-ray, CT scanning and MRI examination before surgery. There were 16 cases of central type, and 6 cases of paracentral type. All patients were treated surgically by modified eggshell technique via posterior approach. Results The mean operative time was 210 min (range, 180-300 min), with a mean blood loss of 860 ml (range, 600-1200 ml). All surgeries were performed successfully without neurological symptoms aggravation. Surgical complications included dural laceration in 2 cases, both dural lacerations were repaired intraoperatively, epidural hematoma in 1 case with lower extremity neurological symptoms, full neurologic recovery was observed after surgical removal of the hematoma. All patients were followed up for average 27.5 months (range, 12-54). The mean JOA score increased from 3.36±1.79 before operation to 7.45±2.99 after the operation at 12 months follow up, and the mean improvement rate of neurological status was 58.3%±30.7%. There was significant difference in JOA score before and after surgery(t=10. 12,P＜0.01 ).The results of 14 cases were ranked as good, 6 as fair, 2 as unchanged, and none as worsened. All cases obtained bony fusion without instrument failure. Conclusion Modified eggshell technique enable ventral and dorsal spinal decompression from the posterior approach in cases of hard thoracic disc herniation, with reduction of the rate of postoperative paralysis.

BACKGROUND: Degenerative lumbar spinal stenosis could be treated by laminectomy internal fixation placement,unilateral or bilateral decompression,posterior laminectomy and so on.However,whether laminectomy internal fixation placement can be used remains unclear.OBJECTIVE: To evaluate the efficacy of interbody fusion cage implantation of pedicle screw fixation,in combination with posterior lumbar laminectomy,bilateral resection and decompression of the inferior articular process,autologous facet joint bone transplantation in the treatment of degenerative lumbar spinal stenosis.METHODS: A total of 41 patients of degenerative lumbar spinal stenosis,who failed after 3 months of conservative therapy,including 23 males and 18 females,at a mean of 60.3 years,Received posterior lumbar laminectomy,bilateral inferior articular process resection and decompression,autologous facet joint bone and cage interbody fusion implant pedicle fixation.They were followed up for 24 months,preoperative and postoperative Japanese Orthopedic Association(JOA)score evaluations were performed to assess the therapeutic efficacy of the patients,radiological examination was done to investigate the graft fusion and vertebral stability of surgical segments in patients.RESULTS AND CONCLUSION: During the follow-up,JOA score significantly increased compared with the preoperative score(P＜0.01)and clinical excellence rate was 90%; 40 cases obtained bony fusion,with a fusion rate of 98%,1 patient exhibited signs of lumbar instability.There was no loosening,fracture and other complications after internal fixation,but 2 cases appeared dural tear,1 case pedicle position deviation,1 case pseudoarticulation formation.The results suggest that the posterior lumbar laminectomy,bilateral inferior articular process resection and decompression,autogenous facet joint bone and cage interbody fusion implanted pedicle screw fixation show good clinical effects for the treatment of degenerative lumbar spinal stenosis.

Objective To determine the expression and distribution of Disabled-2(Dab2) in normal human adrenal glands, and further to study the expression of Dab2 in tissues of different adrenocortical adenomas, and to elucidate whether Dab2 can be a specific molecular marker in the pathology of primary aldosteronism. Methods Real-time PCR and immunohistochemical staining were used to detect Dab2 expression in 10 aldosterone-producing adenoma (APA) samples, 8 cortisol-producing adenoma ( CPA) samples, 8 non-functioning adenoma ( NFA) samples and 6 normal adrenal samples. Results Immunohistochemical staining showed that Dab2 was significantly highly expressed in zona glomerulosa of normal human adrenal glands. Sporadical cluster of ZG cells with moderate Dab2 staining were demonstrated in APAs. In all CPA and NFA tumors, weak dab2 staining was detected. According to the results of real-time PCR, Dab2 mRNA expression was increased significantly in APAs compared with normal adrenal glands. There was no significant difference between normal adrenal glands, CPAs, and NFAs in regard to Dab2 mRNA expression. Compared to nontumor portions, APAs also showed higher Dab2 mRNA expression in the tumor( P<0. 05). Conclusion Dab2 was predominantly localized in zona glomerulosa in normal adrenal gland. Increased Dab2 mRNA expression was detected in APAs compared with normal adrenal glands. Whereas, Dab2 protein expression was just moderate increased in APAs. Weather Dab2 can be a specific molecular marker in the pathology of primary aldosteronism has to be further studied.
