Noninvasive continuous positive airway pressure (CPAP) for the ventilation treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS) is the first-line treatment method. This article aims to describe the effect of surgical operation especially for the UPPP in the individualized comprehensive treatment of OSAHS and the importance of surgical technique. Lower compliance is the bottleneck of CPAP therapy in clinical application, for the OSAHS patients with treatment failure in CPAP or those cannot accept CPAP therapy, when with no other ideal instrument therapeutics, accurate diagnosis of position in airway obstruction with an adequate surgical operation is the treatment,of choice. Surgical operation is particularly important either as a fore-lying means to improve the CPAP treatment compliance or as an independence treatment method of OSAHS. The pharyngeal cavity is the most common obstructive plane in patients with OSAHS. The operation of traditional UPPP aiming at the expansion of pharyngeal cavity is the classics surgery to solve obstruction in this plane, the lower operation effective rate is the main reason of restriction in its development. How to improve the effective rate of surgical treatment of OSAHS is our surgical goal. The effective rate of surgical operation treatment in OSAHS rely on the following sides: to follow the OSAHS individualized comprehensive treatment principle, reasonable choice of surgical operation indication, the precise localization diagnosis of upper airway obstruction, adequate surgical operation and skilled surgical techniques.

Objective To observe the effect of high-dose vitamin C on MMP2 expression and invasive ability in PANC-1. Methods Transwell invasion assay was used to compare the invasive ability of PANC-1 cells in different concentrations of vitamin C treated groups. RT-PCR and Western blot were used to detect and compare the levels of MMP2 mRNA and protein expression in each group. Results Compared with the 0mM vitamin C treated group, the mRNA expression of MMP2 was significantly decreased in 1.0,5.0,10. 0mM group(0. 510 ±0. 004 vs 0. 792 ±0. 006, 0. 391 ±0. 007 vs 0. 792 ±0. 006, 0. 282 ±0. 008vs 0. 792 ± 0. 006, P ＜ 0. 05 ). Compared with the 0mM vitamin C treated group, the protein expression of MMP2 was significantly decreased in 1.0,5.0,10. 0mM group(0. 519 ±0. 004 vs 0. 761 ±0. 014,0. 310 ±0. 007 vs 0. 761 ±0. 014,0. 297 ±0. 008 vs 0. 761 ±0. 014, P ＜0. 05). Compared with the 0mM vitamin C treated group, the invaded cell number was significantly decreased in 1.0,5.0,10. 0mM groups ( 452 ± 22 vs653 ± 28,340 ± 32 vs 653 ± 28,409 ± 33 vs 653 ± 28, P ＜ 0. 05 ). Conclusion High-dose vitamin C can decrease the expression of MMP2 in PANC-1 cells, and weaken its invasive ability.

This study examined the dynamic characteristics of upper airway collapse at soft palate level in patients with obstructive sleep apnea/hypopnea syndrome (OSAHS) by using dynamic 3-Dimensional (3-D) CT imaging. A total of 41 male patients who presented with 2 of the following symptoms, i.e., daytime sleepiness and fatigue, frequent snoring, and apnea with witness, were diagnosed as having OSAHS. They underwent full-night polysomnography and then dynamic 3-D CT imaging of the upper airway during quiet breathing and in Muller's maneuver. The soft palate length (SPL), the minimal cross-sectional area of the retropalatal region (mXSA-RP), and the vertical distance from the hard palate to the upper posterior part of the hyoid (hhL) were compared between the two breathing states. These parameters, together with hard palate length (HPL), were also compared between mild/moderate and severe OSAHS groups. Association of these parameters with the severity of OSAHS [as reflected by apnea hypopnea index (AHI) and the lowest saturation of blood oxygen (LSaO(2))] was examined. The results showed that 31 patients had severe OSAHS, and 10 mild/moderate OSAHS. All the patients had airway obstruction at soft palate level. mXSA-RP was significantly decreased and SPL remarkably increased during Muller's maneuver as compared with the quiet breathing state. There were no significant differences in these airway parameters (except the position of the hyoid bone) between severe and mild/moderate OSAHS groups. And no significant correlation between these airway parameters and the severity of OSAHS was found. The position of hyoid was lower in the severe OSAHS group than in the mild/moderate OSAHS group. The patients in group with body mass index (BMI)≥26 had higher collapse ratio of mXSA-RP, greater neck circumference and smaller mXSA-RP in the Muller's maneuver than those in group with BMI<26 (P<0.05 for all). It was concluded that dynamic 3-D CT imaging could dynamically show the upper airway changes at soft palate level in OSAHS patients. All the OSAHS patients had airway obstruction of various degrees at soft palate level. But no correlation was observed between the airway change at soft palate level and the severity of OSAHS. The patients in group with BMI≥26 were more likely to develop airway obstruction at soft palate level than those with BMI<26.

Objective:In order to prevent misdiagnosis and degrade death rate, we explored the early diagnosis and correct treatment methods of traumatic pseudoaneurysm of internal carotid artery in sphenoid sinus,. Method: The clinic data of 6 cases who had traumatic pseudoaneurysm of internal carotid artery in sphenoid sinus and were admited in our hospital were analyzed retrospectively. Large numbers of literature about the disease were re-viewed. Some early diagnosis methods and optimal treatment schemes were proposed. Result: All patients had a history of cranium trauma and recurrent attacks nasal hemorrhage. There are two patients with a complication of sight loss in single eye. In the six cases, one case was treated with unilateral common carotid artery ligation, three cases were treated with aneurysm and internal carotid artery embolism by using sacculus proprius which is able to shedding , one case was treated with internal carotid artery embolism by using tiny circlip ring . These five pa-tients were crued with no severe complication. One patient death of hemorrhea. His nasal cavity was tamponaded repeatly because repeat nasal hemorrhage. However, he had never treated with internal carotid artery embolism. Conclusion:The patients who have traumatic pseudoaneurysm of internal carotid artery usually die of unmanageable hemorrhea. The patients may be cured if they could obtain an early diagnosis and correct treatment.
