By analyzing competency-based neurosurgery residency training mode, the training methods for innovative ability of competency-based neurosurgeon are further discussed, for the purpose of reforming the training mode of neurosurgeon, improving creative ability and scientific clinical thinking ability.

ObjectiveTo evaluate the value of application of spiral CT with 3D reconstructure on diagnosis and treatment of tibial plateau fractures.Methods15 cases of tibial fractures treated with x-ray and 16-slices spiral CT,3 D images were made,fractures were classified and evaluated with 3D images and treated with correct treatment.ResultsAll of the 15 patients got correct diagnosis by 16-slices spiral CT with 3D reconstructure,1 failed by x-ray.10 fractures were operated under 3D reconstructure guide and operation proved fractures revealed by 3D reconstructure finally.ConclusionSpiral CT with 3D reconstructure could offer more accurate location and classification of tibial plateau fractures,and it had obvious advantage on demonstration of spatial relationship,and it also could provide better planning and management for the tibial plateau fractures.

AIM: To compare the clinical results of suture method and partial eyelash resection treating for pediatric eyelid trichiasis, and screen an effective method for the treatment of pediatric lower eyelid trichiasis.
METHODS: Fifty-six cases of pediatric patients with lower eyelid trichiasis were randomly divided into a control group and an observation group in accordance with the method of drawing lots, and each group was 28 cases. The control group was treated with suture method, and the observation group was treated with partial eyelash resection. The clinical efficacy, patient satisfaction before and after treatment, and the incidence of complications were compared.
RESULTS:(1) The clinically total effective rate was 74%of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups ( P<0. 05 ); ( 2 ) the satisfaction scores were (3. 89±1. 22) points and (6. 27±1-86) points of the the control group before and after treatment, which were ( 4. 00±1. 34 ) points and ( 8-95±2-34) points of the observation group, and there were statistical differences of the two groups before and after treatment (P<0. 05), and the scores of the observation group were higher than that of the control group ( P<0-05);(3) complications such as swelling and stitches off appeared in both groups, and the rate was 21% in the control group, which was 11% in the observation group, and there were statistical differences between the two groups (P<0. 05).
CONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation;partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

0.05). Conclusions There was markedly immunoresponsiveness unbalance in acute phase of IM.The large number of mononuclear cells consisted mainly of activated CD8 + T cells.The decrease of CD4 +CD 25 + regulator T cells might be involved in pathogenesis of IM,which provided one of the new ways to treat EBV-associated diseases.

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of immunosuppressive cells derived from bone marrow stem cells.MDSCs can not only strongly inhibit the anti-tumor immune reactions mediated by T cells,but also directly accelerate angiogenesis,tumor progression and metastasis.Nonresolving inflammation (NRI),a major driving factor in the occurrence and development of tumor,and MDSCs are present in tumor microenvironment and become hot topics in recent years.However,the relationships between MDSCs and NRI,especially in the relevant molecular regulatory networks,have not been fully elucidated.The relationships between MDSCs and NRI,the molecular regulatory networks,the key regulatory points and the strategies for targeted treatment are reviewed in this paper based on the current literatures and the work achieved by our research team.

Aim To construct and express the fused gene of anti-glioma single chain Fv(39ScFv)/ human tumor necrosis factor α (TNF-α ). Methods The mature peptide cDNA of TNF-α was fused to 3′ -terminus of ScFv gene. The 39ScFv-TNFα fusion gene was cloned into expression vector pET20b(＋ ) and induced to express in E.coli. Results The fusion protein expressed in E.coli account for 20％ of the total bacterial protein. It displayed a single band of Mr 44 000 by reducing SDS-PAGE and Western blot, and retained both of its anti-glioma immunoreactivity and biological activity of TNF. Conclusion The fusion gene was constructed and expressed successfully in E.coli. The fusion protein possessed bifunctional activities, it may prove useful in targeting immunotherapy against glioma.

Objective To provide reliable technical method by identifying referential anatomic landmarks for retroperitoneal laparoscopic renal surgery,with respect to the renal hilum and renal artery.Methods The regional anatomy of the posterior abdominal wall was studied in 35 cases of retroperitoneal laparoscopic renal surgery from January to August 2010.These included 27 cases of renal cancer,6 cases of renal pelvis cancer and 2 cases of renal tuberculosis.Distended the retroperitoneal space using balloon dilation along with sharp and dull dissection.We recorded the forms and positions of the posterior abdominal cavity's anatomical landmarks and evaluated the relationship between each anatomical landmark with respect to the renal hilum and renal artery.Results The perirenal fascia posterior layer and perinephric fat on the renal side were observed,and several anatomical landmarks gradually appeared on the posterior abdominal wall.The diaphragm extended across the upper retroperitoneal space near the superior pole of the kidney,and the psoas major and the quadratus lumborum muscles were located at the lower retroperitoneal space,near the inferior part of the kidney.The intersection of the upper diaphragm muscle with the lower psoas major and quadratus lumborum muscles were bordered by the lateral and medial arcuate ligaments.The lateral arcuate ligament arched across the upper part of quadratus lumborum,while the medial arcuate ligament arched across the upper part of psoas major.The medial arcuate ligament points extended towards the upper border of the renal hilum.These landmarks enable us to locate the position of the kidney,reach the renal hilum and identify the renal vessels in all 35 cases.Conclusions The relative position of the muscles and ligaments of the posterior abdominal wall are consistent and can be clearly seen under retroperitoneoscopy.Based on the position of the diaphragm and psoas major,the kidney can be located.In addition,based on the position of the medial arcuate ligament,the renal hilum and renal artery can be located.Assistance from these anatomical landmarks will simplify the retroperitoneal laparoscopic renal surgery.

Objective To investigate the feasibility and safety of retroperitoneal laparoendoscopic single-site (LESS) donor nephrectomy using home-made single-port device.Methods From January 2011 to June 2012,11 consecutive LESS left donor nephrectomies using home-made single-port device with conventional laparoscopic instrument were performed through retroperitoneal access in our center.Results The procedures were completed and no complications occurred in all donors.Mean operative time was 149.5 min.Estimated blood loss was 30-350 ml.Warm ischemia time was 2-4 min.The urine output was prompt in all cases.Recipient graft function was normal within 2 weeks.Donor hospital stay was 5-6 days after operation.Conclusion LESS donor nephrectomy using home-made single-port device in our initial experience is feasible and safe.It is also cost-effective and minimally invasive with conventional laparoscopic donor nephrectomy.This technique is a good option for living donor nephrectomy.
