ABSTRACT
Objective To investigate the relationship of PRL-3,tumor associated macrophages and lym-phangiogenesis in papillary thyroid carcinoma. Methods SP immunohistochemistry was used to study the levels of PRL-3,CD68,and D2-40 in papillary thyroid carcinoma and thyroid adenoma.Results The positive expression rates of PRL-3,CD-68 and D2-40 were higher in papillary thyroid carcinoma than those in thyroid adenoma (P < 0.01). High PRL-3,CD-68 or D2-40 was associated with lymphatic metastasis in patients with papillary thyroid carcinoma(P<0.01).Conclusion The expression levels of PRL-3,CD-68 and D2-40 are positively cor-related in papillary thyroid carcinoma,and they are related to invasion and lymphangiogenesis of papillary thyroid carcinoma.
ABSTRACT
OBJECTIVE@#To evaluate nasal ventilation in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) after nasal cavity ventilation expansion techniques by using acoustic rhinometry.@*METHOD@#Thirty-eight patients with mild OSAHS and 17 patients with moderate OSAHS who were diagnosis by PSG were selected. The acoustic rhinometry and rhinomanometry were used to assess the nasal cavity volumes (NCV), nasal airway resistance (NR), nasal minimal cross-section area (NMCA) and distance of nasal minimal cross-section area from nostril (DCAN) before and after the surgery (6 month later).@*RESULT@#The state of mild OSAHS group in NCV, NMCA and NR: before surgery (2.41 ± 1.33) cm³, (0.37 ± 0.39) cm², (2.07 ± 1.48) cmH₂O/(L · min), after surgery (2.53 ± 1.54) cm³, (0.45 ± 0.34) cm², (1.69 ± 1.03) cmH₂O/(L · min), has significant difference (P 0.05).@*CONCLUSION@#There was an objective evaluation of nasal ventilation in OSAHS patients after surgery by using acoustic rhinometry.

OBJECTIVE@#To evaluate nasal ventilation in allergic rhinitis patients after nasal provocation with acoustic rhinometry.@*METHOD@#Twenty AR cases were selected. Each one was assessed for the nasal cavity volumes (NCV), nasal airway resistance (NR), nasal minimal cross-section area (NMCA) and distance of nasal minimal cross-section area from nostril (DCAN) by using acoustic rhinometry before and after nasal provocation 1 hour and 6 hours later. The results were statistically analyzed.@*RESULT@#After nasal provocation 1 hour 1 later, NCV and NR had a significant difference compared with before nasal provocation(P 0.05). After 6 hours later, NCV, NR, NMCA and DCAN had a significant difference compared with before nasal provocation (P 0.05).@*CONCLUSION@#The nasal ventilation in allergic rhinitis after nasal provocation had declined over time.
