BACKGROUND: The key to success in laryngeal transplantation is to control the infection. In practice, how to minimize the risk of infection should be considered first, so that the laryngeal allograft can survive after revascularization under the immunosuppressive state. Then the therapeutics methods should be focused on the functional recovery of respiratory, swallowing and phonation.OBJECTIVE: To explore the feasibility of staged allogeneic larynx transplant for dogs in order to decrease the infection rate.METHODS: Ten male conspecific Beagle dogs were assigned into five pairs of donor and receptor according to body mass and the size of larynx. The allogeneic larynx was embedded under the neck skin by allotransplantation. The dogs were treated with immunosuppressant daily to resist immnological rejection. The pharynx and trachea were contraposed after larynx survived to establishⅡstage laryngeal transplantation animal model.RESULTS AND CONCLUSION: InⅠstage of laryngeal transplantation, the laryngeal allograft survived well, blood supply was passable. Receptor dog 1 with vertical midline incision in the neck, receptor dogs 4 and 5 with transverse incisions in the neck grew well. No infection phenomena was found in receptor dogs 4 and 5. The lastⅡstage laryngeal transplantation was performed in the 4th week afterⅠstage laryngeal transplantation. Skin flap necrosis occurred in receptor dogs 2 and 3 with U-shape incisions. The donor larynx had different degree infection. Laryngeal allograft of receptor dog 2 died; laryngeal allograft of receptor dog 3 survived after treatment. The survival period of donor larynx in receptors was as long as 4 weeks. These findings indicate that the larynx infection is avoid or reduced by staged larynx transplantation with pre-embed laryngeal allograft after total laryngectomy. The receptor dog is tolerant; the donor larynx is easy to survive. The main histological change occurs in the epithelial mucosae which can be used as an inspect index of immunosuppressive agents. However, glandular organ secretion is a troublesome problem and immunodepressant must be continuously administrated for a long time.

Objective To evaluate and screen out the specific characters of thyroid nodules on grayscale and color Doppler ultrasonography. Methods One hundred and four thyroid nodules in 95 patients were studied with gray-scale and color Doppler ultrasound before surgery.According to the probability of malignancy,the main independent characters were screened out by Logistic regression analysis and then got the formula which could calculate the probability of malignancy.Results Fifty three nodules,included 44 hyperplasia,7 adenomas,1 switch granuloma and 1 Hashimoto's disease,were benign.Fifty one nodules,included 47 papillary carcinomas,3 medullary carcinomas,1 metastatic carcinomas,were malignant pathologically.The significant characters to differentiate malignant from benign were the shape,margin,border,halo,echostucture,echogenecity,echo uniformity,calcicum,bolood vessel shape and partial abnormal rich blood of thyroid nodules.After two variables logistic regression analysis,a fomula were worked out.Probability of malignancy=1/1+e-z,which z=-7.44+1.30×halo+1.05×calcicum+1.5×vessel shape.If a thyroid nodule with no halo,microcalcicum and irregular vessel shape,the probability of malignancy was 0.99,while with complete halo,no calcicum and regular vessele shape,the probability of malignancy of the nodule was 0.02.Conclusions The halo,calcium and blood vessel shape of thyroid nodules were three independent characters of thyroid nodules to predict malignant thyroid nodules on gray scale and color Doppler ultrasound.

Objective To observe the enhancement pattern and time-intensity curve of endometrial carcinomas by using contrast-enhanced ultrasound(CEUS). Methods Altogether 30 endometrial carcinomas were evaluated with real-time gray-scale CEUS, using pulse inversion harmonies technique. The enhancement patterns were observed. Twenty tumors were compared for the size between traditional ultrasound and CEUS. In 21 cases, the parameters of time-intenaity curve were compared between the endometrial lesion and un-involved myometrium. Results The contrast agent arrived at the feeding vessels firstly and then branched into the endometrial tumors. All of the endometrial tumors were enhanced completely except for the necrosis area. In 73.3 % (22/30) of cases, the tumors washed out earlier than the un-involved myometrium. By using CEUS 76. 7% (23/30) of cases showed the feeding vessels of tumor. 43.3% (13/30) of cases showed more clearly than traditional ultrasound in tumor base, position and boundary. The mean enhancement sizes of tumor were bigger than the size showed by traditional ultrasound in 85% of cases by (0. 62±0.50)cm. More than 90% cases showed the tumors start to enhance and wash-out earlier than or at the same time as myometrium. The arrival time and peak time of cancer group were significantly earlier than myometrium group. The peak intensity, enhancement intensity and the rising rate of the tumor group were significantly higher than those of the myometrium group. Conclusions There are some characteristic points in CEUS of endometrial carcinomas. CEUS can provide richer information in tumor imaging than traditional ultrasound and has certain clinical value.

OBJECTIVE To explore the feasibility of transnasal endoscopic surgery to treatment of intraorbital space occupying by ethmoidal-lamina papy-racea approach. METHODS The clinical data of 10 cases who underwent intraorbital surgery via transnasal endoscopic ethmoidal-lamina papyracea approach from June 2003 and Aug. 2006 were retrospectively studied. The patients included foreign body 1 case, cavernous hemangioma 2 case, lipoma 2 cases, inflammatory pseudotumor 2cases and hematoma 3cases. All intraorbital space occupying were operated by transnasal endoscopic ethmoidal-lamina papyracea approach but for one cavernous hemangioma which was dealt with through extra orbitectomy. The inflammatory pseudotumors were prescribed with glucocorticoid after operation.RESULTS Foreign body was removed successfully. One case of cavernous haemangioma was removed completely by transnasal endoscopic surgery and the other by extroorbital operation. All symptoms of proptosis and diplopia disappeared. One vision was enhanced from hand moving to 0.3 and another from light to hand moving. However, there was one hematoma which had been hindered about 14 days after damaged lost eyesight after operation. All cases were cured but one pseudotumor which recurred and was operated again. All cases were followed up 3 to 24 months. CONCLUSION Intraorbital surgery via transnasal endoscopic ethmoidal-lamina papyracea approach was available and feasible for the advantages of clear operation field, direct vision operation, less damage, rapid recovery and avoiding of facial scar, and intranasal endoscopic surgery can treat the rhino-orbital related diseases and nasal diseases at the same time.
