Objective To evaluate the surgical procedures and both oncological and functional outcome in patients with bone tumors of the shoulder girdle.Methods Seventy-one patients including 61.pts with malignant tumor and 10 pts with giant cell tumors of the shoulder girdle treated in our department from July 1998 to July 2006 were studied retrospectively.According to the location,there were 15 pts with scapula tumor and 56 pts with proximal humeral tumor.Forty-two male pts and 29 female pts were included in this study with an average age of 36.5 years old ranging from 11.to 62 years old.Surgical procedures:forequarter amputation in 10 pts;Scapulectomy in 3 pts;Scapulectomy and artificial scapular replacement in 3pts;partial scapulectomy and proximal humerus resection with prosthetic reconstruction in 8 pts;proximal humerus resection and prosthesis replacement in 47 pts.Results Due to adequate soft tissue was preserved,the mean functional score was 28 for the pts with giant cell tumor according to MSTS functional scoring system,compared with the functional score 23 for the pts with malignant tumor because the deltoid muscle insertion was resected in the latter group.Among the thirty-seven patients with osteosarcoma,local recurrence occurred in four cases(10.8%),lung metastasis in five and bone metastasis in two.The seven patients died of disease.One patient iagnosed of malignancy in giant cell tumor died after distal metastasis.thtee patients with Ewing sarcoma died of the disease.No recurrence Wag observed in both five humeral chondrosarcoma and five scapular chondrosarcoma.Conclusion Tumot resection and proximal humeral prostbesis replacement is the optimal method for the sarcoma of shoulder girdle in term of preservation of elbow and hand function.Preservation of abductor insertion is necessary for good abduction function.The metastatic rate of proximal humeral osteosarcoma was lower than that of lower extremities.also the prognosis of oncological outcome.Intra-articular and extra-atticular tumor resection produced similar local recurrence rate in the present study,which suggested intra-articular resection may be an altemafive procedure.

Neonatal nerves exist in tumor tissues,and tumor cells can invade nerve by neurogenesis.Current research shows that cancer cells can secrete cytokines to promote the differentiation and growth of nerve cells,in turn,the differentiation and growth of nerve cells can stimulate tumor development and metastasis.Neurogenesis is one way of interaction bettween tumor cells and microenvironment similar to angiogenesis and lymphangiogcnesis,which has a major impact on biological behavior of tumor cells and prognosis.

Objective To evaluate the value of double stapling technique with curved cutter stapler in colorectal anastomosis,especially in low colorectal anastomosis. Methods The clinical data of 168 cases of rectal carcinomas treated with double stapling technique with curved cutter stapler were retrospectively reviewed.The intraoperative condition,postoperative complications and findings during follow up were analysed. Results During the operations,the processes of closure and anastomosis of all the patients were satisfactory,and no operative death occurred.After the operations,4 cases(2.4%) had anastomotic leakage,3 cases(1.8%) had anastomotic bleeding,and 2 cases(1.2%) had rectovaginal fistula.All the complications were cured.There was no anastomotic stricture. Conclusion Double stapling technique with curved cutter stapler may help to accomplish low colorectal anastomosis which is a difficult task for handed suture.

OBJECTIVETo observe the therapeutic effects of steel plate fixation after the failure of arthrodesis of ankle by screw fixation.

METHODSFrom August 2001 to October 2011, 15 patients were with steel plate fixation after failure of arthrodesis of ankle by screw fixation. Among patients, 9 cases were males and 6 cases were females,ranging age from 40 to 65 years old with the average of 56 years old. Ten cases were in left and 5 cases were in right. Screws were removed and steel plate was fixed intraoperatively, and plaster external fixation for postoperation. Clincal effect were evaluated according to AOFAS scoring system from pain, waliking ability and aligment before and after operation, and X-ray was used to evaluate joint fusion after operation.

RESULTSAll patients were followed up, and the duration ranged from 4 months to 4 years with an average of 2 years. The incison were healed in stage I. No ankle pain,injury of blood vessel and nerve,infection and farilure of internal fixation occuerred. The AOFAS score increased from 36.86 +/- 8.32 preoperatively to 85.09 +/- 4.65 (t = -26.366, P = 0.000).

CONCLUSIONSteel plate fixation after the failure of ankle arthrodesis of screw fixation has the advantages of rigid stability, simple manipulation and high success rate, less pain, perfect recovery.

Objective To explore the competency of community health administrators in a survey of such administrators at large in Shanghai. Methods McClelland's Competency Dictionary was used to set two benchmark positions, while the behavioral event interviewing and questionnaires were made to survey 19 community health service centers in Shanghai. Results The competency model benchmarking on the head of a medical branch consists of 6 character clusters, 11 characteristic items, 27 evaluation dimensions and 27 typical behavior descriptions. The model benchmarking on the community team leader consists of 5 character clusters, 8 characteristic items, 21 evaluation dimensions and 21 typical behavior descriptions. Conclusion Findings of the survey provide objective criteria for competence appraisal of community health administrators, and serve as reference for formulating their development plans as well.

Objective To investigate the expression and significance of nuclear transcription factor-?B(NF-?B) in childhood acute lymphoblastic leukemia(ALL) and the effect of dexamethasone(DEX) on its expression,to provide the experimental base for corresponding clinical treatment of the ALL,in which NF-?B is taken as a target.Methods 1.The biotin-streptavidin method was used to detect NF-?B P65 protein on 20 childhood ALL patients and 20 healthy children.2.The effect of DEX at clinically relevant dosage on NF-?B P65 protein were also detected by the biotin-streptavidin method.Results 1.The positive expression rate of NF-?B P65 protein in childhood ALL patients was 85.50%,obviously higher than that in normal group(10.0%)(?~2=22.56 P

With the development of functional genomics, high throughput analysis of genes’ function has been the mainstream of research, and exogenous gene's over expression via Agrobacterium-mediated transformation is the most commonly used method in gene functional analysis.The versatile plant expression vector cassette named pBHT-5 was constructed by the method of site-specific mutagenesis based on pBI121. First of all, the restriction enzyme SfiI recognition site in trfA gene (X00713) which was relevant to plasmid replication and stability was replaced without changing its amino acid composition. And then the SfiIA,SfiIB sites were added between promoter CaMV35s and terminator NOS. The versatile plant expression vector cassette can be directly used to construct plant expression vector containing the full-length genes cloned by Clontech SMARTTM technology, which will raise the efficiency of vector construction. The result will provide basis of new genes’ high throughput screening and functional analysis, then get the new genes functioning in plant osmotic stress resistance.
