Objective To study the MRI features of nasopharyngeal carcinoma (NPC) in patients who presented with ocular abnormalities. Methods The clinical signs and MRI features of Ⅲ, Ⅳ and/or Ⅵ cranial nerve involvement in 22 cases of histologically proved nasopharyngeal carcinoma were retrospectively analyzed. Results All 22 cases showed perineural tumor spread along the course of Ⅲ, Ⅳ and Ⅵ cranial nerve. Diplopia was the most common sign, occurred in 14/22 patients. The incidence of incomplete palsy of Ⅲ, Ⅳ and Ⅵ cranial nerve were 16/44, 7/44 and 4/44, respectively. There were four types of abnormal MRI findings: cavernous sinus thickening (10/44) and mass ( 16/44), superior orbital fissure enlargement (4/44) and abnormal signals (9/44), thickened oculomotor muscles with obscured adjacent fatty space and abnormal enhancement (10/44). The dynamic contrast enhancement patterns of the masses in cavernous sinus and orbital were the same as that of nasopharynx lesions; all appeared as rapid initial enhancement followed by a plateau phase. Conclusion Oculomotor nerve involvement can be the first clinical signs of NPC, and MRI can show the perineural extension along the Ⅲ, Ⅳ and Ⅵ cranial nerve in NPC.

Objective To observe the morphological features of the incisive canal in normal anatomy and abnormalities with multi-slice spiral CT (MSCT). Methods MSCT findings of 108 normal subjects and 65 patients with abnormalities involving incisive canal were retrospectively analyzed. Results The normal incisive canal were classified into 3 types according to the morphology of the nasal opening:two openings, short bony crest and one opening (37.04%, 33.33% and 29.63%, respectively), as well as cylinder, Y-shaped and pyramidal (59.26%, 37.04% and 3.70%) in coronal images, and cylinder, pyramidal and fusiform (84.26%, 14.81% and 0.93%) in sagittal images. The maximum diameter of the nasal and palatal opening was (4.67±1.31) mm and (3.51±0.88) mm (P<0.05). The length of the incisive canal was (10.71±1.95) mm, (11.51±1.97) mm in male and (9.91±1.58) mm in female respectively, and gender difference was found (P<0.05). The angle between the posterior wall and the hard palate was (118.51±9.44)°. The upper and lower length from the anterior wall of the incisive canal to the cortical palate was (9.29±1.26) mm and (7.12±1.21) mm, respectively (P<0.05). The manifestations of abnormalities involving incisive canal including enlargement (47.69%), narrowing (46.15%), shortening (3.08%) and interruption (3.08%) were observed. Conclusion The morphology of the incisive canal can be clearly delineated with MSCT and post processing techniques. It is extremely valuable for avoiding potential complications during surgical procedures such as implant placement and helpful to the diagnosis and treatment of abnormalities involving maxillary incisive canal.

Objective: To evaluate the clinical effcacy of the modiifed anterolateral minimally invasive plate osteosynthesis technique for distal humeral shaft fracture, and to explore its feasibility, security, advantage and disadvantage. Methods: hTe clinical effcacy of 17 patients with distal humeral shatf fracture, who were treated with the anterolateral humerus minimally invasive plate osteosynthesis during 2009 to 2012, were retrospectively analyzed. hTe operative time, bleeding volume, complications, esseous union time and range of motion (ROM) of elbow were recorded, and the functional outcome of elbow joint was evaluated by Mayo elbow performance score (MEPs). The varus angle was measured in the malunion patients atfer the distal humeral shatf fracture healed. Results: All of the 17 patients obtained bony union at an average of 19.2 weeks postoperatively, an average of 4.5 screwes were inserted in distal humerus. hTe mean ROM of elbows was 133° and the MEPS were 98.2. Seven patients suffered humeral malalignment and the mean varus degrees were 8.3°. Conclusion: hTe technique of anterolateral humerus minimally invasive plate osteosynthesis is safe and feasible for distal humeral shatf, and the satisfactory clinical outcomes can be obtained by this modiifed technique. However, some of the patients may appear malunion with varus angulation of humerus.

Objective To determine the prevalence of metabolic syndrome ( MS) in women who had gone through natural menopause, and to provide basic data for developing effective prevention and intervention of metabolic syndrome in Taixing area Jiangsu province. Methods A cluster sample of natural postmenopausal women aged 45 to 64 years were sampled and assessed by questionnaires, physical measurements, and biochemical tests; and analyzed according to the International Diabetes Federation ( IDF, 2005) diagnostic criteria for MS. Results The crude prevalence of metabolic syndrome was 35. 25% and the standardized prevalence rate was 31. 47% after age being adjusted. The prevalence of metabolic syndrome was increased with age ( P < 0. 01). The constituent ratio of the combinations of 3, 4, and 5 components in MS was 21. 45% , 10. 73% , and 3. 07% , respectively. Conclusion The prevalence of the metabolic syndrome among older women after menopause is high and increasing with aging. Public education should be strengthened to improve the quality of life in postmenopausal women and prevention and intervention should be adopted earlier as well.

OBJECTIVE To detect the expression of the Glucocorticoid receptor-?(GR-?)mRNA in nasal polyp and normal nasal mucosa and investigate the route of nasal drug administration in patients of nasal polyp. METHODS The expression of GR-?mRNA in 101 samples of nasal polyps and 31samples of normal nasal mucosa was examined by using Fluorescent quantitative PCR .RESULTS The level of GR-?mRNA in normal nasal mucosa(135.4? 5.25)?104 copy /?g were significantly higher than that in nasal polyps(23.5?12.1)?104 copy/?g . CONCLUSION Because of the low expression of GR-?mRNA in nasal polyps,the route of nasal drug administration in patients with nasal polyps may be in the part of normal mucosa,not in the mucosa of nasal polyps of the nasal cavity.

A method based on stable isotope dilution gas chromatography-mass spectrometry ( GC-MS ) was established to determine five kinds of organophosphate esters ( OPEs ) in different kinds of cosmetics. For cream and wax-based cosmetics, samples were extracted by appropriate solvent, and then purified by ENVI-Carb solid phase extracting column. For powder and aqueous samples, GC-MS test could be operated directly after solvent extraction and concentration. All of the samples were separated by DB-5MS (30 m×0. 25 mm× 0. 25 μm) chromatographic column, and detected by selected ion monitoring ( SIM ) mode. The target analytes were qualitatively confirmed by retention time and abundance ratio of characteristic ions, and quantified by stable isotope diluted internal standard method. Under the optimized conditions, the linear coefficients of the OPEs were larger than 0. 9995, the detection limits were 1. 0-30 μg/kg, the average recoveries ( n=6 ) ranged from 89 . 5% to 105%, and the RSDs were in the range of 2 . 9%-9 . 1%. The developed method, which was characteristic by satisfactory purification effect, favorable matrix effect elimination capacity, as well as high recovery, was suitable for the determination of OPEs in different kinds of cosmetic matrices.
