Objective: To improve the understanding of the clinical feature and early diagnosis of relapsing polychondritis(RP). Method: Eleven patients with RP were analyzed retrospectively and the reported literatures were reviewed. Result: Nine cases had initial involvement of auricular cartilage while two polyarthritis. The treatment of 2RP patients with respiralory tract involvement was invalid and 1 patient died. Nine cases were initially misdiagnosed, with a misdiagnosis rate of 81.82%. Conclusion: RP involves cartilage and connective tissue. The prognosis with respiralory tract involvement is poor. RP is a sort of paroxysmal and progressive inflammation involving cartilages all over the body with a variety of clinical manifestations. Early diagnosis of RP is based on full understanding of its clinical features.

Objective To study the influence of furosemide on the currents of the delayed rectification potassium channel and sodium channel of mice's spiral ganglion neurons.Methods Postnatal mice(P1～P6) spiral ganglion neurons were obtained by mechanical dissociation and enzymolysis.Delayed rectification potassium channels' currents and sodium channels' currents were recorded with whole-cell patch clamp techniques.Observed was the influence of furosemide on potassium channels and sodium channels.Results When furosemide was added around the spiral ganglion neurons,the delayed rectification potassium currents were inhibited to around +200～+300 pA,and sodium currents were inhibited to about 30% of peak current.Furosemide was washed away after working steadily for 1 minute,5 and 10 minutes.The delayed rectification potassium currents could recover to 98%,64%,and 25% of the peak currents before and sodium currents could recover to 96%,76% and 54% of the peak currents accordingly.Conclusion The currents of delayed rectification potassium channels and sodium channels could be inhibited by furosemide to different degrees.The longer furosemide was used,the greater damage could occur in the ion channels.

Objective To evaluate the efficacy of minimally invasive percutaneous intervertebral disc approach for treatment of sympathetic cervical spondylosis. Methods Fifty?six patients diagnosed as having sympathetic cervical spondylosis from January 2009 to August 2014, aged 22-64 yr, with the dis?ease course ranged from 6 months to 15 yr and a follow?up period of 6 months, were enrolled in the study. The related minimally invasive approach was selected according to the height of the diseased intervertebral space. When the ratio of the height of diseased intervertebral space∕normal intervertebral space≤1∕3, per?cutaneous radiofrequency ablation was used ( groupⅠ, n=19); when the ratio within the range of 1∕3-2∕3, percutaneous laser disk decompression was used ( groupⅡ, n=12); when the ratio≥2∕3, low?tem?perature plasma radiofrequency ablation was used ( group Ⅲ, n=25) . Before operation, at 2 weeks after operation, and at 1, 3 and 6 months after operation, the sympathetic symptoms were evaluated using the 20?point score. At 2 weeks and 6 months after operation, the patients′ subjective satisfaction was assessed and graded ( excellent, good, medium and poor ) . Results All the patients were followed up for 6 months. The sympathetic symptom scores were significantly lower at each time point after operation in Ⅰand Ⅲ groups and at 2 weeks and 3 and 6 months after operation in group Ⅱ than those before operation
( P<0.05) . The excellent and good rate of patients′subjective satisfaction was 67.9% at 2 weeks after op?eration, and 76.8% in the last follow?up period at 6 months after operation. Conclusion The minimally invasive percutaneous intervertebral disc approach has a marked short?term effect on sympathetic cervical spondylosis.

OBJECTIVE: To explore a method for locating the area of lacrimal sac in dacryocystorhinostomy under endoscopy. METHOD: Sixty-eight patients were performed dacryocystorhinostomy under endoscopy. Take light spot of ocular optic fiber as the lacrimal sac projection to the lateral wall of the nasal cavity position. RESULT: With the guiding of ocular optic fiber, lacrimal sac can be located accurately. The operating time of dacryocystorhinostomy under endoscopy was shortened significantly, and the operation procedure was simplified. All patients were followed up for 2 years, only 2 recurrent cases were found. The success rate reach to 97.06% (66/68). CONCLUSION Ocular optical fiber used in locating the lacrimal sac in dacryocystorhinostomy under endoscopy is simple and feasible, and can be widely used.

OBJECTIVE: To get a method of dacryocyst allocation for dacryocystorhinostomy per nasal endoscope. METHOD: The dacryocyst of 7 chronic dacryocystitis cases(8 eyes) were located through nasal cavity guided by endo-ophthalmic optical fiber. RESULT: All the 7 patients got successful operations, the bleeding was 10-20 ml during the operation , postoperative recovery was good, no infection occurred. Five patients received operations twice, all of them were detained anaesthetic tubes for 3 to 6 months, dacryocyst rinsing were conducted once per month after extubation. No obstructions and complications occurred after one year follow up. CONCLUSION Endo ophthalmic optical fiber can be used to locate dacryocyst in dacryocystorhinostomy per nasal endoscope.
