Objective:To investigate the clinical value on the determination of the peripheral blood ICAM 1 level in Graves's disease(GD).Methods:The serum soluble Intercellular Adhesion Molecule 1(sICAM 1)concentration were analyzed by ELISA and the expression of ICAM 1(CD54 +) on PB lymphocytes in 37 GD patients and 22 normal subject were measured,while TsAb,TpoAb,TGAb;CD4 +,CD3 +,CD8 +,CD19 +,CD25 +were examined by FACS.Each marker between the two groups and the positive rate between the TsAb and sICAM 1 whe compared.In addition ,the relationship between the ICAM 1 level on PB and immunity markers in GD patients were analysed.Results:The mean sICAM 1 concentration was significantly higher in untreatd GD patients than in normal controls(P

Objective: To observe the level of pro-opiomelanocortin (POMC) mRNA expression in the hypothalamic arcuate nucleus in young and senile rats. Methods: POMC mRNA was determined with in situ hybridization, the hybridization signals and areas of POMC mRNA-positive cells were measured with computer image analysis system. Results: Compared with young rats, average gray values of POMC mRNA-positive neurons in the hypothalalmic arcuate nucleus and near region in the senile rats decreased, but the numbers of POMC mRNA-positive neurons did not change significantly. Conclusion: The decrease of POMC mRNA expression level in individual neurons in hypothalamic arcuate nucleus of senile rats is one of the causes that decrease the expression of peptides-derived from POMC gene.

OBJECTIVE: To evaluate the applicative value of computer assisted navigation system in endoscopic sinus and skull base surgery. METHOD: Forty-nine endoscopic surgery procedures were performed with the help of computer assisted navigation system, among which there were 25 cases of recurrent sinusitis and nasal polyps, 9 cases of nasal and sinus tumour, 7 cases of cerebrospinal fluid rhinorrhea, 2 cases of meningoencephalocele, 4 cases of congenital choanal atresia, 1 case of pituitary tumor and 1 case of foreign body in middle cranial fossa. RESULT: The preoperative time was 5-13 minutes for preparation, 7 minutes in average. The target error was less than or equal to 1.5 mm. All the 49 cases had successful surgery without complications. CONCLUSION Computer assisted navigation system can help the surgeon to determine the sinus, skull base and adjacent anatomic landmarks correctly, improve surgical accuracy and safety, and reduce intraoperative and postoperative complications.

OBJECTIVE: To evaluate the clinical value of dual-source computer tomography in the diagnosis of suspicious airway foreign bodies in children. METHOD: Twenty-two children of suspicious airway foreign bodies were examined by DSCT. The original scanning data were reconstructed with MPR, MinP, CTVE and VR. The results were compared with surgical findings. RESULT: The position, size, shape and accompanying signs of foreign bodies were clearly demonstrated by DSCT. Twenty cases were diagnosed as foreign bodies in the airway by DSCT. Nineteen cases were confirmed as foreign bodies. Purulent discharge was found by bronchoscopy in 1 case. The rate of conformed diagnosis was 95%. CONCLUSION DSCT can demonstrate the foreign body clearly and play an important role in the diagnosis of suspicious airway foreign body in children.

Objective To analyze the clinical treatment modalities and clinical prognosis of patients diagnosed with primary nasopharyngeal adenoid cystic carcinoma (NACC).Methods The medical records of 46 patients with NACC between March 1971 and November 2015 were retrospectively analyzed.Among them,22 patients were male and 24 female.The median age of all patients was 47 years (range:23-74 years).Among them,34 patients received radiotherapy alone including 25 patients treated with conventional radiotherapy and 9 receiving intensity-modulated radiation therapy (IMRT).Five patients underwent salvage surgery for the residual tumors after radiotherapy.Twelve patients were treated with a comprehensive treatment modality (surgery combined with radiotherapy).Results The median follow-up time was 66.0 months (range:11.0-270.6 months).The 5-and 10-year overall survival,locoregional failure-free survival,and distant metastasis failure-free survival rates were 70％ and 40％,64％ and 47％,70％ and 62％,respectively.In the radiotherapy alone group,12(35％) cases obtained complete response,13 had partial response and 9 remained stable after radiotherapy.The 5-year overall survival and locoregional failure-free survival rates in the radiotherapy alone and combined therapy groups were 69％ and 74％,63％ and 66％,respectively (all P＞ 0.05).Conclusion The course of NACC is relatively slow.Radiotherapy is recommended for patients with high sensitivity towards radiotherapy.Salvage surgery is feasible for those who are insensitive to radiotherapy or with residual tumor after radiotherapy.

Objective:Continuous acquisition of swallowing images of head and neck cancer patients by using MRI technique was performed to observe and measure the movement regularity and maximum displacement of the soft palate, tongue and larynx.Methods:From July 2018 to October 2018, 20 patients with primary head and neck cancer were chosen randomly, 17 male and 3 female. The median age was 58.5 years (28 to 78 years). Among the 20 patients, 7 patients were diagnosed with nasopharyngeal carcinoma, 3 patients with oral cancer, 5 patients with oropharyngeal cancer, 3 patients with hypopharyngeal cancer, and 2 patients with nasal and paranasal sinuses cancer. Two patients were classified as stage Ⅰ-Ⅱ, 8 patients as stage Ⅲ and 10 patients as stage Ⅳ according to the eighth edition of AJCC.Results:The displacement of the upward movement of the soft palate during swallowing was (1.06±0.31) cm and followed the pattern normal distribution. The displacement of backward movement of the soft palate was (0.83±0.24) cm, which also almost normally distributed. The displacement of backward tongue movement was (0.77±0.22) cm and followed the normal distribution pattern. The displacement of upward tongue movement was 0 in patients with tongue depressor for image acquisition. The mediandisplacement of upward tongue movement in patients without tongue depressor was 1.23 cm (0.59 to 1.41 cm). The displacement of upward laryngeal movement was (1.14±0.22) cm and followed the normal distribution pattern, and the median displacement of forward laryngeal movement was 0.4 cm (0.27 to 0.90 cm).Conclusions:Swallowing movement may occur in head and neck cancer patients during radiotherapy. It can also cause the movement of gross tumor volume (GTV) and surrounding normal tissues. Therefore, extensive attention should be paid to the individual distance between GTV and planning gross tumor volume (PGTV) when making radiotherapy plans, aiming to ensure the prescription dose of cancer.

OBJECTIVETo evaluate the expression and possible modulation of heme oxygenase-1 (HO-1) in nasal polyps of patients with chronic rhinosinusitis with nasal polyps (CRSwNP).

METHODSNasal polyps and uncinate process tissues were collected from 25 CRSwNP patients and 19 healthy controls with nasal septal deviation. HO-1 expression was examined using qRT-PCR, immunohistochemistric staining and Western blot analysis. Moreover, additional uncinate process mucosal samples of 15 healthy controls with nasal septal deviation were harvested for nasal explant culture experiments. HO-1 expression was measured in cultured nasal explant in response to specific inflammatory and glucocorticoid stimulation. SPSS 20.0 software was used to analyze the data.

RESULTSThe mRNA and protein expression of HO-1 was significantly increased in polyp tissues, 1.220±0.397 in mRNA and 1.409±0.701 in protein, compared with healthy controls 0.464±0.318 in mRNA and 0.017±0.1147 in protein (U=22.00 in mRNA and U=1.00 in protein, both P< 0.05). The immunohistochemical results showed that HO-1 was mainly distributed in the epithelial layer, submucosal glands and inflammatory cells in nasal tissues. Nasal explant culture experiments demonstrated that HO-1 mRNA was upregulated by IL-17A. The HO-1 mRNA level before the stimulation was 1.000, and 17.264±4.275 after the stimulation of 1 ng/ml IL-17A (U=0, P<0.05), 19.128±4.605 after the stimulation of 10 ng/ml IL-17A (U=0, P<0.05), but was significantly suppressed after stimulation with glucocorticoids (dexamethasone, DEX). The mRNA level after the glucocorticoids stimulation was 0.370±0.101 (U=0, P<0.05) and 0.316±0.167 (U=0, P<0.05) respectively. Furthermore, the HO-1 mRNA was inhibited by TGF-β1, the mRNA level was 0.217±0.322 (U=0, P<0.05), 0.070±0.070 (U=0, P<0.05), respectively.

CONCLUSIONIncreased HO-1 expression may play a role in the pathogenesis of CRSwNP, which may be considered as the therapeutic target.
