OBJECTIVE: To compare the consistency of four olfactory psychophysical test methods. METHOD: Twenty out-patients were done with olfactory psychophysical test and the results were analyzed. The four olfactory psychophysical test methods include simple test method, UPSIT, Sniffin Sticks test and the T&T olfactometer test. RESULT: The consistency of four test methods reached 85%, and UPSIT test can identify pseudo smell obstacles. CONCLUSION There is reliable and stable outcome of the four psychophysical olfactory test methods.

[Objective]To report the result of percutaneous biopsy in bone tumor and analyze the interrelated influence factors.[Method]A total of 171 patients were subjected to trocar puncture for biopsy of bone tumor in pre-operation,and the results of all cases were reviewed.[Result]Totally 155 cases in 171 cases showed positive outcome,the positive rate was 90.64%.The accuracy of 98 cases was comfirmed in 122 postoperative pathology diagnoses,and the acuracy rate was 80.33%.There were 110 cases of tumor.Biopsy sensitivity was 95.41%,and biopsy diagnostic particularity was 100%.[Conclusion]Percutaneous biopsy is both effective and valuable for the diagnosis of bone tumor in pre-operation,but the biopsy positive rate and accuracy,and postoperative complication was highly related to the operator cognitive level of bone tumor and meticulous manipulation and so on.

The pleomorphic adenoma of epiglottis is rare. When the tumor grows larger, some patients may have symptoms of pharyngeal foreign body sensation, but other patients have no obvious symptom. The tumor is mainly found through indirect laryngoscopy or electronic laryngoscopy. This disease can be confirmed by pathological diagnosis after tumor resection.

Objective To establish a method for the determination of gallic acid in Gongyanping Dispersible Tablet by HPLC.Method A HPLC method was performed on Hypersil ODS column(4.0?250 mm,5 ?m).The mobile phase was acetonitrile(0.2 %CH3OH)-water solution of 0.1 %triethylamine and 0.1 %phosphoric acid(1 ∶99).The detection wavelength was 220 nm and flow rate was 1.0 mL/min.Results Gallic acid showed a good linearity in the range of 0.022～0.352 ?g,r=0.999 9.The average recovery was 99.70 %,and RSD was 1.61 %.Conclusion This method is effective and can be used for the quality control of Gallic acid in Gongyanping Dispersible Tablet.

OBJECTIVE: To analyze the clinical significance of ocular vestibular evoked myogenic potentials (oVEMP) and cervical vestibular evoked myogenic potentials (cVEMP) in primary unilateral benign paroxysmal positional vertigo (BPPV). METHOD: Fifty-two patients with unilateral primary BPPV (BPPV group) and 38 normal subjects (control group) received ocular vestibular evoked myogenic potential (oVEMP) and cervical vestibular evoked myogenic potential (cVEMP) test using tone burst stimuli. The response rate, latency and amplitude were analyzed. RESULT: In BPPV group, the response rate of oVEMP was 46.15% in lesioned side and 48.08% in healthy side, respectively. The response rate of cVEMP was 67.31% in lesioned side and 65.38% in healthy side, respectively. In control group, the response rate on the left ear was 84.21% for oVEMP and 92.11% for cVEMP. On the right ear, was 81.58% for oVEMP and 94.74% for cVEMP in control group, there was no significant difference in cVEMP and oVEMP P1, N1 N1-P1 latency and amplitude between left and right ear. The interaural amplitude ratio and asymmetry of cVEMP and oVEMP was significantly different between BPPV group and control group (P<0.05). CONCLUSION Unilateral primary BPPV with bilateral impaired vestibular otolith pathways function can be objectively evaluated by oVEMP and cVEMP detection. Abnormal oVEMP responses were more frequently detected than cVEMP.

OBJECTIVE: To explore the inhaled and food allergen distribution of patient with allergic rhinitis in north of Zhejiang and to analyze the difference of allergen distribution among different age groups. METHOD: One thousand and forty eight patients in north of Zhejiang diagnosed with allergic rhinitis in our outpatient department were tested with skin prick test (SPT). The positive rate of inhaled and food allergens were calculated. To analysis the difference of positive rate between children and adult. RESULT: Nine hundred and eighty-eight cases (94.3%) had the positive reaction. Dermato phagoides farinae and Dermatophagodies pteronyssinus had the highest positive ratio (72.1%, 71.8%) in inhalation group, followed cockroach (14.1%). In food group, Shrimp and peanuts had the highest positive ratio (18.3%,14.2%). Between children group and adults group, positive rate of food allergen was significantly different (P < 0.05), but of inhaled allergen was not significantly different. CONCLUSION The distribution of some allergens in children group and adults group was variable. The study shows that Dust mite was the mostly responsible common allergen in north of Zhejiang.
