Objective To investigate the effect of a tissue engineered trachea for replacement fabricated using three dimensional scaffold and chondrocytes by in vitro and in vivo culturing. Methods Rib chondrocytes were isolated and expanded to two passages, then seeded in PLGA or Dacron scaffold at density of 5 × 107/ml. Cultured in vitro for two weeks, the chondrocytes-scaffold model was planted under dorsal skin between nude mice's spine. Histology of cartilage, neovascularization and organizational structure were observed with HE staining, PAS staining and electron microscopic scan were performed after 4,6,8 weeks in vivo. Results Organized structure were observed in both PLGA-chondrocyte model and dacron-chondrocyte model with cartilage formation, neovascularization and tight fibrous connective tissue between scaffold and skin after in vitro and in vivo culture. Conclusion Tissue engineered trachea fabricated using rib chondrocytes and PLGA or dacron scaffold with in vitro and in vivo culture meets the requirement of trachea replacement.

Objective To investigate the clinical and pathological characteristics of urocpithelial sarcomatoid carcinoma of the urinary system,and improve the diagnosis and treatment of these tumors.Methods We reviewed the pathology comfirmed urinary system caicinoma at the General Hospital of PLA from January 1999 to December 2010 and analyzed the clinical and pathological data of cases with sarcomatoid carcinoma in them retrospectively according to the literatures. Results A total of 4386 urinary system carcinoma were comfirmed,among them 18 (0.41％) cases of sarcomatoid carcinoma were identified,including 13 from bladder,4 from ureter and 1 multiple neoplasm of pelvis and ureter.The patients,11 males and 7 female,had a median age of 63.3 years (41-84 yrs).Gross hematuria (18 cases) were the main presenting symptoms,3 with flank pain,4 with pollakisuria,urgency and dysuria (urinary irritation symptoms] and 5 with urinary obstruction.The patient with multiple neoplasm of pelvis and ureter received allograft renal transplantation 7 years ago and took anti-rejection drugs all the way after operation.17 patients underwent surgical resection,9 radical cystectomy,5 radical nephroureterectomy,3 partial cystectomy and the remain was biopsy.Tumor size ranged from 2.5 to 12 cm (median,5.6 cm).Microscopically,coexisting high grade urothelial carcinoma was present in all the 18 cases,12 with sarcomatoid differentiation,3 with sarcomatoid and squamous carcinoma differentiation and 3 with sarcomatoid and glandular differentiation.Sarcomatoid component occupied 10 -90 percent.Immunohistochemical testing showed the sarcomatoid cells were positive for cytokeratin (CK) and vimentin.12 patients died of disease 20 days to 42 months (median,5.3 months) postoperatively.3 patients have been surviving with tumor free for 3,3 and 17 months respectinely,and the other 3 was failure to be followed. Conclusions Sarcomatoid carcinoma of the urinary bladder is a highly malignant disease,and the prognosis is very poor.The diagnosis depends on histopathologic and immunohistochemical studies.Early diagnosis and cystectomy or nephroureterectomy together with chemotherapy/radiotherapy may improve the curative effect.

OBJECTIVE: To assess the effect of one-stage repair of secondary nasolabial deformity and nasal septoplasty for cleft patients on nasal airway resistance (NAR). METHOD: Using active anterior rhinomanometry, NAR was measured in eighteen patients with cleft lip and palate who suffered form one-stage repair of secondary nasolabial deformity and septoplasty at per-and-post operation. RESULT: NAR was (0.664 +/- 0.200) kPa/(s x L) before operation, (0.304 +/- 0.180) kPa/(s x L) six months after operation, and (0.396 +/- 0.250) kPa/(s x L) twelve months after operation respectively. The differences are statistically significant (P < 0.01) between the NAR before and after operation. Subjective impression score of nasal patency was 7.5 +/- 1.5 before-operation, 2.1 +/- 2.0 after-operation for six months, 3.0 +/- 2.4 after-operation for twelve months. There are significant differences in the subjective impression score of nasal patency as well (P < 0.01). CONCLUSION Correction of septal deformities play a very important role in the operation for secondary nasolabial deformity, which can decrease NAR and improve the subjective impression of nasal patency.

OBJECTIVE: To explore the therapeutic methods and effect of pingyangmycin injection in huge hemangioma at Hypopharynx and laryngeal under suspension laryngoscopy. METHOD: To ananysize the medical records of 12 Patients with giant hemangioma at hypopharynx and laryngeal. Patients were underwent polysomnography before operation. Inseted the suspension laryngoscopy to pars laryngea by mouth to exposing the hemangioma under general anaesthesia, then injected Pingyangmycin by a long-tube needling (one time per three weeks, accumulated dose less than 50 mg). RESULT: Among all patients, ten were cured and two showed obvious improvement. The data of PSG after operation indicates that the symptom of anoxia of post-operation were significantly ameliorated than that of pre-operation, no recurrence occurred during one year follow-up of the hemangioma. CONCLUSION The methods of pingyangmycin injection under suspension laryngoscopic surgery is significantly enhanced clinical effect and improved the life quality of patients with huge hemangioma, which with low risk, high security, can ameliorating anoxia, complete cure, and is a ideal therapeutic measure.

Objective To explore the method and the clinical effects of surgical treatment for severe hedge brain injury at frontotemporal bottom. Methods 96 patients with severe hedge brain injury at frontotemporal bottom were scored by GOS before surgery. Then unilateral or bilateral craniotomy was carried out,via a large flap incision in the site of frontotemporal and parietal hair,and the blood clots within the surgical fieldand the inactivation brain tissue having been fell off were removed, and the contusion lesions of brain bottom were exposed, and the inactivation brain tissue was cleared. If the brain injury was serious ,the removal of frontal pole and temporal pole should be proper. Discretion to The removing or replacing the bone flap should be based on consideration of the circumstances. Six nonths or one year after injury,96 patients were scored by GOS again. Results There were 17 cases of grade Ⅰ(17.71%) ,11 cases of gradeⅡ (11.46%),13 cases of gradeⅢ (13.54%),21 cases of grade Ⅳ(21.86%),34 cases of grade Ⅴ (35.42%) in 96 patients. Conclusion Early surgical treatment of severe hedge brain injury at frontotemporal bottom could improve the cure rate and reduce the rate of disability.

Objective To evaluate the safety and effectiveness of balloon kyphoplasty combined with physiotherapy in the treatment of osteoporotic vetcrbral compression fractures (OVCFs). Methods A retrospective review was of 12 OVCF cases ( including 16 fracture vertebrae) treated with balloon kyphoplasty was performed. Each patient had also been treated with anti-osteoporotic medication and the Rehabilitation of Osteoporosis Program-Exercise (ROPE) protocol, and each had received a six-month follow-up visit. The following parameters were recorded before the operation and 1 day and 6 months afterward : fracture recurrence, the severity of pain before and after treatment, and the change of vertebral height. The severity of pain was evaluated by using a visual analogue scale (VAS). Results During the treatment, no complication or adverse event was found. The average VAS values preoperation, postoperation and at the 6-month follow-up were 7.6±1.3, 2.1±1.2 and 2.6±1.4, respectively. The average changes in vertebral height preoperation, postoperation and at the 6-month follow-up were 49.2±18% , 74.3 ±14% and 69.8±16% respectively. All of the measures evaluated improved noticeably after the combined treatment. Conclusion Balloon kyphoplasty combined with anti-osteoporotie medication and physiotherapy showed good effects in the treatment of osteoporotic veterbral compression fractures.
