Objective To analyze the effect of cervical.curvature and intervertebral height on the surgical outcome of posterior decompression in patients with multi-level cervical spondylotic myelopathy.Method A total of 50 patients with multi-segment cervical spondylotic myelopathy (≥ 3 segments),treated with posterior decompression from June 2006 to January 2009 were retrospectively analyzed.Twenty six patients underwent cervical omni-posterior decompression and lateral mass screw internal fixation (group A); 24patients underwent expansive open-door laminoplasty (group B).The effects of changing of cervical curvature and intervertebral height on JOA score and VAS score were analyzed.Results All patients were followed up for 8 months to 4 years (average,24 ±5.5 months).There were statistical differences of cervical curvature angles between preoperative and 3 days postoperatively in group A,while no statistical differences in group B.There were no statistical differences of cervical curvature angles between 3 days,6 months and 3 years postoperatively in group A,while there were differences in group B After further analysis of the loss of cervical curvature and intervertebral height,the result showed that JOA score and VAS score in the low-loss group were better than those in the high-loss group.Conclusion Lateral mass screw internal fixation after cervical omni-posterior decompression had many advantages such as reducing the change of cervical curvature,the loss of intervertebral height and incidence of cervical axial symptoms.

In 2012,Beijing Children’s Hospital established the Beijing Children’s Hospital Group to explore the new model of public hospital reform.This study covered the target setting,management framework,network system,and sharing mechanism of the group,and discussed the merits and setbacks of such a practice,for insights of public hospital reform.

Objective To probe the application of superimposed flaps in hand surgery. Methods Form March 1998 to December 2003, we repaired 35 cases of skin defects with non trunk blood flaps and neurocutaneous vascular flaps. The area of flaps ranged from 1cm?1cm to 6cm?8cm. Results After operation, the flaps in 33 cases survived, but died in 2 cases due to unsuitable design. The follow ups ranging from 6 to 12 months showed that the quality and color of the survived flaps were similar to those of the normal tissue around. No swelling was found. Conclusion The superimposed flaps have reliable blood supply so that they are an ideal means to repair skin defects of hand.

OBJECTIVE To investigate the transgenerational effects of a hypothala mic-pituitary-ad-renal (HPA)axis -associated neuroendocrine metabolic progra mming alteration fro m F1 to adult second generation (F2)with prenatal ethanol ingestion.METHODS Pregnant Wistar rats were ad ministered with ethanol (4 mg·kg -1·d -1 )fro m gestational day 1 1 until delivery.F1 rats were fed a high-fat diet fro m postnatal week 4 (PW4)and were cross-mated in PW 16 -20.F2 rats were fed a standard diet fro m PW4 and rectal te mperature was measured in PW20,oral glucose tolerance test (OGTT)was con-ducted in PW21 ,blood sa mples and hypothala mus were collected in PW24 to investigate seru m lipids and HPA axis activity.RESULTS Co mparing to the F2 control group ,rectal te mperature in F2 ethanol group were higher (P<0.01 ),sugar tolerance in F2 male group was i mpaired (P<0.05),seru m corti-costerone and hypothala mus arginine vasopressin (AVP) mRNA were increased (P <0.05);seru m insulin were decreased (P<0.05)and male rats showed i mpaired glucose tolerance (P<0.05);seru m high-density lipoproteincholesterol (HDL-C)decrease (P <0.05)and total cholesterol (TCH)/HDL-C and low density lipoproteincholesterol (LDL-C)/HDL-C ratios were markedly increased (P <0.05,P <0.01 ).CONCLUSION Prenatal ethanol exposure induced metabolic syndro me has transgenerational effects,which may originate fro m the intrauterine progra mming of altered HPA axis-associated neuroen-docrine metabolis m.

Objective To explore the relationship between the inflammatory reaction and insulin function in children with critically ill.Me-thods Ninty-six children with critical disease in Oct.2003 to Oct.2006 were enrolled in the study.Blood sugar,plasma insulin,C-peptide,tumor necrosis factor(TNF)-?,C reactive protein(CRP)were measured in the peak period and convalescence.Results Blood sugar and plasma levels of insulin,C-peptide,TNF-?,CRP were significantly higher in the peak period than those in the convalescence(Pa

In order to isolate genes related with the osmoadaptation and glycerol metabolism of Candida glycerinogenes, a transformation system based on the dominant selectable marker Zeocin and restriction enzyme-mediated integration (REMI) was established. Effects of seven restriction enzymes on transformation efficiency of C.glycerinogenes were tested. Transformation conditions were optimized in the presence of Hind III. Under the optimal conditions of OD_ 600 ≈1.3, voltage of 1.5 kV, 2.0?10~9 competent cells/mL, 100 units of Hind III added, the transformation efficiency was up to 129 trnaformants/?g DNA. 58% of transformants were stable on nonselective medium. These results suggest that REMI technique would be beneficial to the genetic transformation of C.glycerinogenes.

OBJECTIVETo investigate the therapeutic experience of gastrointestinal stromal tumors (GIST) and to analyze the pathological features and prognostic factors of GIST.

METHODSThe clinicopathological and follow-up data of 181 patients with GIST admitted in Renji Hospital between January 1999 and December 2007 were analyzed retrospectively. All the cases were grouped according to Fletcher's risk scheme. Life table and COX regression model were used to evaluate the prognostic factors.

RESULTSOut of 181 tumors, 107(59.1%) were located in stomach, 51 (28.2%) in intestine and 23(12.7%) in colorectum or other sites. Distant metastases,including liver metastases were found in 7 patients intraoperatively. Tumor size ranged from 0.5 to 30 cm with the mean of 7.02 cm. The positive rate of CD117 was 94.5% (171/181) and that of CD34 was 86.2% (156/181). One hundred and seventy-six patients underwent complete resections, including multi-organ resections in 26 patients. The other patients underwent palliative operations. The 1-, 3- and 5-year overall survival rates of 181 patients were 95.2%, 87.9% and 78.5% respectively. Univariate analysis revealed age, tumor size, primary organ of tumor, mitotic count, Fletcher's classification and multi-organ resection were associated with survival rate. No significant difference of sex was existed among groups. COX hazard proportional model revealed that advanced stage and large tumor size indicated worse prognosis. Eight patients with high risk of recurrence and 3 patients with recurrence and metastasis were stable after receiving imatinib therapy.

CONCLUSIONSThe diagnosis of GIST depends on endoscope and CT. Fletcher's classification is simple and effective to evaluate GIST behavior and prognosis. Surgical resection is still the main therapy for GIST and targeted therapy will play a more important role for prognosis in the future.
