Objective The purpose of this study was to research the expression of Twist in cervical cancer tissues and the relationship between its expression and clinicopathologic characteristic, and to investigate the role of twist in cervical cancer invasion, metastasis and progress. Methods Immunohistochemistry was used to detect the expression of the Twist in 78 cases of middle and advanced stages cervical cancer tissue microarray chip. The relationship between its expression and clinicopathological characteristic was analyzed. Results (1) The positive expression of twist in cervical cancer was 56/78 (71.8%);(2) The expression of Twist in cervical cancer was significantly related to tumor histology type, FIGO stage, lymph node metastasis and differentiation degree. With the increase of FIGO stage, the emergence of lymph node metastasis and the decrease of differentiation degree, the expression of Twist increased gradually ( <0.05) . Conclusion The expression of Twist may be closely related to the invasion, metastasis and progress of cervial cancer.

Objective The patients with metastatic spinal tumors often suffered from severe back pain and spinal cord compression directly caused by tumor tissue or severe spine kyphosis.In order to treat or prevent spinal cord paralysis,decompression and stabilization should be performed on the patients with spinal pain and /or severe spinal cord compression.Methods From July1998through July2001,62patients(27women and35men)with metastatic spinal tumors had been treated at our department.Of 62patients,the thoracic vertebrae were involved in37cases,lumbar vertebrae in19and cervical vertebrae in6.Among43of 62patients who pre sented with neurological dysfunction,24patients were incompletely para plegic and the others were completely paraplegic.The fol low-up ranged from8to36months.Results Pain relief was ob-tained in58of 62patients(94%),and good neurological recovery was obtained in33of the43patients.Improved bowel and bladder function was obtained in12of 25patients who presented with bowel and blad der dysfunction.After decompression,neurological function,evaluated as Frankel grade E or D,was ob-tained in5patients whose neurological function had been evaluated as Frankel grade A or B,and other9pa-tients ex perienced a neurological recovery from Frankel grade A or B to C or D.Conclusion The time developing from neurological dysfunction to complete para plegia is the most important prognostic factor.Poor prognosis is often inevitable when complete paraplegia appeared less than48hours.Complete loss of bowel and bladder function is also a factor for poor prognosis.Decompression should be performed immedi -ately if the patient is presented with neurological dysfunction.Spinal metastasis of thyroid or breast cancer has a rela tive good prognosis.However,metastasis of lung or liver cancer is associated with a short-term survival.Neu rological function of patients with spinal metastasis at thoracic region is more difficult to recover.Com-mon motor and sensory functions are often improved earlier than bowel and bladder function.Thorough re-section of metastatic tumor and stable in ternal fixation should be performed when single vertebra is involved.Conservative tumor resection,decompression and posterior internal fixation should be performed when two or more seg ments are involved in order to alleviate paraplegia,improve spinal stability and the quality.[

Objective To establish the human telomerase reverse transcriptase (hTERT) gene viral transferring system. Methods By means of liposome mediation, a retroviral vector pLNC-hTERT carrying a selectable marker neomycin resistance genes (Neo r) and a target gene (hTERT) was transferred into the ectropic package cells ?-2, and by using the supernatant of ?-2 cells to infect the amphotropic producer clone PA317, established PA317/hTERT package cell line. In order to get higher-titer virus, the supernatants of ?-2 infected PA317 repeatedly. Human endothelial cells were used to detect the effect of gene transfer. Results We established a PA317/hTERT package cell line which produced high-titer virus. The viral titer produced by PA317 cells was raised 20 times by repeated infection method, and with higher-titer virus the exogenous genes were successfully transferred into endothelial cell. Conclusion This method can be used to establish higher-titer viral transferring system.

Objective To explore the complications of the total elbow arthroplasty after the resection of the peri-elbow tumor. Methods Between June 1998 and June 2002, eight patients underwent total elbow arthroplasty after resection of tumors, which involved 7 males and 1 female (mean age, 42.6 years; range, 22-63 years). The patients included 1 metastasis, 1 GCT, 2 MFH, 1 osteosarcoma, 1 lymphoma, 1 desmoid fibroma, and 1 synovial sarcoma. The tumors located 3 in distal humerus, and 5 in proximal ulna. For those of the distal humerus, after the resection of the tumors, the origins and the insertions of the musculi flexors, extensor, pronators and supinators were repaired as far as possible. The application of the prothesis was relatively simple, the prosthetic stem of the distal humerus was cemented, the intercondylar notch was sawn off, but both the lateral and medial epicondyles were kept, the prothesis impacted in the notch; While for those tumors located on the proximal ulna, the stem was spiraled in the intramedullary cavity, Patients were evaluated according to the Mayo Elbow Performance Score. Results All the patients were followed up at least one year or to death (mean duration, 2.5 years). Pain scores decreased from a mean of 3.6 to 2.0. Mean elbow motion from extention to flexision arc improved from 29? to 73? (range, 55?-105?). Seven cases were excellent or good (87.5%), and only one was poor (12.5%). There were none of the complications, such as infection, incision non-union and nerve injury. All patients without local recurrence as well. The X-ray didn't reveal any sign of loosening or breakage for the artificial elbow joint. Conclusion Total elbow arthroplasty after resection of tumors can decrease the pain and improve the function substantially. For metastatic tumors, this technique can be also used to alleviate symptom if there is no other good option.

?AIM:To compare the curative effect of conjoint fascial sheath( CSF) suspension and levator muscle resection for moderate or severe congenital ptosis.?METHODS: Forty - three patients ( 74 eyes ) with moderate or severe ptosis were treated by CSF suspension or levator muscle resection randomly, and followed up for 6mo. The normalization rates of the two operations were then compared by statistical method, and the complications of the two operations were analyzed.?RESULTS: The two operations appeared no significant difference on the normalization rate for moderate congenital ptosis (P>0. 05), while the normalization rate of CSF suspension on severe congenital ptosis was significantly higher than that of levator muscle resection (P<0. 05). Less complication was happened in the CSF suspension group than in the levator muscle resection group.?CONCLUSION:CSF suspension is more effective on the treatment of severe congenital ptosis than levator muscle resection, and has advantages such as less trauma, repeatable, and less complication.
