OBJECTIVE: To assess the diagnosis and therapeutic effects for fungal otitis externa by clinical symptoms, endoscopic findings, and fungus culture of the ear discharge. METHOD: Sixty outpatients diagnosed with otitis externa were enrolled in the study. All patients were treated with a thorough debridement of the ear and one antifungal medication regimens (compound resorcinol solution) in case of a positive fungus culture. One subgroup of patients treated with daub glycerol during 2 weeks of follow-up. RESULT: Positive cultures were found in 42 cases. The efficacy was observed in all patients even in those who received only ear endoscopy. CONCLUSION Fungal otitis externa could be easily diagnosed by ear endoscopy. A thorough debridement of the ear and utility of compound resorcinol solution is an easy and effective approach for treatment of fungal otitis externa.

Objective To evaluate the value of neutrophil gelatinase - associated lipocalin (NGAL) for diagnosis of acute kidney injury (AKI) after cardiopulmonary bypass established. Method 120 children undergoing cardiopulmonary bypass were enrolled in this prospectively study. Serial urine samples were analyzed by ELISA for NGAL expression. The primary outcome measure was AKI, which was defined as a 50% or greater increase in serum creatinine from baseline. Result 21 children ( 17.5% ) developed AKI. Urine concentrations of NGAL increased after cardiopulmonary bypass had been established for 2 hours. The concentration of NGAL in urine after cardiopulmonary bypass had been established for 2 hours was used to diagnose AKI. The area under the receiver-operating characteristic curve was 0. 96, the sensitivity was 92%, and the specificity was 91% for the cutoff value of 100ng/mg Cr. Conclusion Concentrations of NGAL in urine might be used as a sensitive and specific biomarker for early prediction of AKI after cardiopulmonary bypass had been established.

Super hydrophobic interface modified with silver nanoparticles was fabricated for the detection of pesticide residues.By using a chemical reduction method,silver nanoparticles were deposited on the substrate surfaces with different microscopic pore structures.Two kinds of composite substrates,including regular stainless steel mesh and cellulose polyester film,were used.The pre-treatment of the substrate with fluoridated reagents was used to form a super hydrophobic interface,which made the target molecules on the surface concentrate effectively.The surface with the cellulose polyester substrate was used to detect Rhodamine 6G (R 6G) effectively with surface enhanced Raman scattering (SERS) technique.The results showed that the detection hmit was 10-16 mol/L.In addition,the surfaces based on the stainless steel mesh and cellulose polyester substrate were used to detect trichlorfon pesticide with detection limits of 1 × 10-15 mol/L and 1 × 10-16 mol/L,respectively.

Computed tomography (CT) is considered the most sensitive method for the detection of intraocular foreign bodies (IOFBs).The purpose of this study was to evaluate a new method of 3-dimentional (3D) localization of IOFBs that takes advantage of the anatomical structure of the optic nerve and to assess the clinical outcomes using this new method.Twenty-two trauma patients with IOFBs or suspected IOFBs admitted to our hospital were scanned with multislice CT (MSCT) between July and December 2003.All scanning was performed with a 16-row spiral CT in axial plane using a sequential scanning protocol.During the scanning,the eyeball of the patient was kept stable and was not allowed to rotate internally or externally.Section collimation was set at 16 mm × 0.75 mm.Table feed was 12 mm.Reconstruction index was 0.75 mm.After scanning,the reconstructed images were loaded into a workstation to create the multiplanar reconstruction images with the aid of the 3D software.We compared the localization results with the operative findings.Multiplanar reconstruction images showed IOFBs in all 22 patients.IOFBs occurred in the eyeball of 14 patients,in the wall of the eyeball of 5 patients and in the posterior orbits of 3 patients.Different surgical procedures were designed according to the localization by this new method and all IOFBs were successfully removed.All of these foreign bodies were metallic and the localization of IOFB using MSCT was consistent with that found by operative findings.It was suggested that MSCT is a simple and effective imaging modality for the localization of IOFBs.In our study,we localized the IOFBs more quickly and accurately by taking advantage of the fixed position of the intraocular segment of the optic nerve,and determined the necessary surgical parameters.

Objective To investigate ultrasound as a therapy for white lesions of the vulva.Methods Immunohistochemistry and hybridization in situ were used to study changes in VEGF protein and mRNA in the vulva skin of rabbits after ultrasound irradiation.Results After irradiation,VEGF protein and mRNA had increased markedly after 4 and 7 days,but their levels recovered by day 14.Conclusion Ultrasound irradiation causes local edema and hypoxia which enhance production of VEGF.VEGF promotes growth of local microvessels and increases the permeability of the endothelial cells of blood vessels.These changes improve nutrition of the mierovessels and nerve endings and ameliorate the microenvironment for tissue growth.One could speculate that ultrasound irradiation helps rehabilitation and regeneration of pathologic vulva skin.

Objective: TO explore the effect of VEGF-C gene transfection on the expression of VEGF-C in human cervical carcinoma HeLa cells and the mechanisms of its anti-apoptosis effect. Methods: The con-structed pcDNA3.1(+)NEGF-C vector was transformed into human cervical cancer HeLa cells and was select-ed by G418. The changes in the expression level of VEGF-C mRNA and protein were determined by semi-quantitive RT-PCR and ELISA. HeLa cells with overexpression of VEGF-C were named as HeLa/S1. The expression level of NF-KB and bcl-2 mRNA was determined by RT-PCR in transfected cells. Results: After transfection by liposome, the VEGF-C mRNA level and the expression of VEGF-C protein in transfected cells were higher than those in the control groups. HeLa/S1 cell line was successfully established. In HeLa/S1 cells, the expression of NF-κB (2.06±0.09 vs 1.35±0.02 vs 1.38±0.02 P<0.05) and bcl-2 gene mRNA (2.02± 0.67 vs 0.41±0.06 vs 0.37±0.06, P<0.05) level were higher than those in the control groups. Conclusion: VEGF-C gene transfection by liposome can increase the expression of VEGF-C in human cervical cancer HeLa cells. NF-κB is stimulated and induces the overexpression of bcl-2 gene in HeLa/S1 cells.

ObjectiveTo classify the type of lumbosacral plexus nerve root injury.MethodsFrom November 2004 to August 2011,36 patients suffered with lumbarsacral plexus nerve root injury underwent surgical exploration in our department.There were 24 males and 12 females,aged from 7 to 49 years(average,29.5 years).By inductively analyzing the location and amount of nerve root injury,preoperative clinical manifestations and results of physical examination,the clinical typing of lumbarsacral plexus nerve root injury was made.ResultsLumbosacral plexus nerve root injury was classified into 6 types:total lumbosacral plexus nerve root injury (4 cases),lumbar plexus and upper sacral plexus nerve root injury (6 cases),sacral plexus nerve root injury (9 cases),upper sacral plexus nerve root injury (11 cases),lower sacral plexus nerve root injury(4 cases) and lumbar plexus injury(2 cases).There were 19 patients with total lumbosacral plexus nerve root injury,lumbar plexus and upper sacral plexus nerve root injury or sacral plexus nerve root injury,among which 73.7％(14/19) nerve root injury located in the spinal canal and all of them were nerve root avulsion or rupture.There were 17 patients with upper sacral plexus nerve root injury,lower sacral plexus nerve root injury or lumbar plexus nerve root injury,among which 64.7％ (11/17) nerve root injury located in intro-pelvic or pelvic sacral foramina,and all of them were distraction injury.ConclusionThis clinical typing is useful for the accurate diagnosis of lumbosacral plexus nerve root injury.In addition,it is also beneficial for judging the location and characteristics of nerve root injury.
