Objective To explore the anatomy for transethmoidal-sphenoid optic nerve decompression under endoscopy and its significance in operation. Methods Fifteen cases (30 sides) of formalin-fixed adult optic canal specimens were dissected under the microscope. The anatomic characteristics of the optic canal and its adjacent were observed, and the relative parameters were evaluated according to nasal endoscopic approach. Results ①The relationship between the optic carotid triangle(OCT)with the optic canal, the ophthalmic artery, the cavernous sinus and the internal carotid artery were invariable, its present ratio were in 66.7%. ②The mean distance from the front margin of nasal columella floor to medial wall of the orbital opening, middle portion and the cranial opening in the optic canal were (72.79 ± 5.40)mm, (75.85 ± 5.10)mm and (79.34 ± 4.95)mm, respectively, and the elevation angles were (39.45 ± 3.68)°, (37.30±4.24)°and (35.45 ± 4.16)°, respectively. ③The mean thickness of sheath in the medial wall of the orbital opening,middle portion and the cranial opening were (0.70 ± 0. 18)mm, (0.51 ± 0.15)mm and (0.49-0.22)mm,respectively. The difference in thickness between the orbital opening and middle portion, the cranial opening were very remarkable(P < 0.01 ). ④The lateral deviate distance from medial wall of the orbital opening, middle portion and cranial opening to sagittal median plane of cadaveric were 1/2 (12.69 ± 2.73)mm、1/2( 19.61± 3.47)mm and 1/2 (25.79 ± 3.23)mm, respectively. Conclusion OCT is the most reliable anatomic landmark to locate the optic canal, and the key point is at the orbital opening of the optic nerve in the optic nerve decompression. It is secure and feasible to cut the sheath from the place where the medial wall crosses the superior wall of the optic nerve.

OBJECTIVE:
To explore a simple and accurate method for localization of upper airway obstruction in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and provide instructions for surgical treatment.
METHOD:
Fifty OSAHS patients confirmed by PSG underwent acoustic rhinometric and pharyngometric assessment by Eccovision. The parameters were recorded, including nasal minimal cross-sectional area (NMCA), distance of MCA from the nostril (DCAN), minimum cross-sectional area at the nasal valve(MCA), nasal resistance (NR) and nasal volume from 0 to 6 cm from the nostril (NCV), as well as pharyngeal cross-sectional area (CSA) and volume from 4.8 to 15.0 cm. The sensitivity and specificity of acoustic rhinometry and pharyngometry on localization of airway obstruction was determined by a comprehensive imaging and endoscopic study.
RESULT:
In 50 cases with severe OSAHS, NMCA, DCAN, MCA, NCV, NR were (0.61 +/- 0.35) cm2, (2.06 +/- 0.12) cm, (0.87 +/- 0.12) cm2, (9.24 +/- 2.31)cm3 and (0.51 +/- 0.32)kPa/(L x min), respectively. Pharyngeal CSA and volume were statistically significantly lower than that in control group (P < 0.01). The value of DCAN was (2.06 +/- 0.12) cm, (9.50 +/- 4.08) cm, (13.10 +/- 2.52) cm in type I II, III patient, respectively. Compared with the control group, the difference was statistically significant.
CONCLUSION
Acoustic rhinometry and pharyngometry is a simple and safe method in localization of airway obstruction in patients with OSAHS.

OBJECTIVE:
To provide transnasal endoscopic optic canal decompression with the anatomic reference.
METHOD:
15 samples of the adult corpse wet specimen (30 sides for the optic canal) were examined under the endoscope to scrutinize the regional anatomy of the optic canal.
RESULT:
distance between the spina nasalis anterior and the midpoint of optic canal medial wall is (61.02 +/- 5.83) mm, and the angle between spina nasalis anterior and the midpoint of optic canal medial wall is (45.1 +/- 4.81) degrees. The medial wall of optic canal is longest, with an average length of (11.61 +/- 1.58) mm; the lateral wall of optic canal is thickest, and the medial wall thinnest. 10 traumatic blind patient underwent endoscopic optic canal decompression with satisfactory outcome.
CONCLUSION
The regional anatomy of the optic canal under endoscope is of importance to endoscopic optic canal decompression. Which is microinvasive with direct approach and clear view thus is widely used in clinical practice.

Objective:
To analyze the correlation between the Spondyloarthritis Research Consortium of Canada (SPARCC) magnetic resonance imaging (MRI) sacroiliac joint inflammation score (SPARCC score)/structural score (SSS) and the disease activity as well as the functional indexs. The correlation between the MRI score and inflammatory indicators [erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)] in patients with active axial spondyloarthritis (axSpA) before and after treatment was explored. In addition, the contribution of the two MRI scoring method in evaluating conditions was also explored.
Methods:
According to the inclusion criteria, 24 patients with active axial SpA were recruited and received the recombinant hauman tumor necrosis factor (TNF)-α receptor Ⅱ: IgG Fc fusion protein(rhTNFR:Fc), sulfasalazine and thalidomide for 12 weeks. Subjects were scored at week 0 and 12 by SPARCC/SSS scores. Bath ankylosing spondylitis disease activity index (BASDAI), Assessment of Spondyloarthritis Intemational Society (ASAS)-endorsed disease activity score(ASDAS)-CRP, bath ankylosing spondylitis functional index (BASFI). Bath ankylosing spondylitis metrology index(BASMI), ESR and CRP. The correlation between the SPARCC/SSS scores and that of clinical indicators were analyzed. Paired sample
