RESUMO
OBJECTIVE:To compare therapeutic efficacy and safety of dexamethasone with different administration routes in the treatment of chronic secretory otitis media. METHODS:A total of 150 patients with chronic secretory otitis media were random-ly divided into control group(75 cases)and observation group(75 cases). Control group was given Dexamethasone sodium phos-phate injection 5 mg by auripuncture under endoscope. Observation group was given Dexamethasone sodium phosphate injection 5 mg via eustachian tube under endoscope. Both groups were given relevant medicine every 2 days,for 3 times in total. Clinical effi-cacies of 2 groups were observed as well as bone conduction threshold under 1,2,4,8 kHz,the levels of water channel protein 1 and water channel protein 4,recurrence,the occurrence of tympanic cavity effusion before and after treatment. The occurrence of ADR was recorded. RESULTS:The total response rate of observation group(93.33%)was significantly higher than that of control group(80.00%);recurrence rate and the incidence of tympanic cavity effusion of observation group were significantly lower than those of control group,with statistical significance(P0.05). After treatment, the levels of bone conduction threshold in 2 groups were significantly lower than before;the observation group was significantly lower than the control group. The levels of water channel protein 1 and water channel protein 4 in 2 groups were significantly high-er than before;the observation group was significantly higher than control group,with statistical significance (P0.05). CONCLUSIONS:The administration of dexa-methasone via eustachian tube under endoscope is significantly better than auripuncture in terms of therapeutic efficacy for chronic secretory otitis media,relieving clinical symptom,improving bone conduction threshold,up-regulating water channel protein level, reducing the risk of recurrence and tympanic cavity effusion. The two routes of adimistration have similar safety.
RESUMO
OBJECTIVE:To investigate clinical efficacy and safety of Fluticasone furoate nasal spray in the treatment of aller-gic rhinitis(AR). METHODS:100 AR patients in our hospital during Jan. 2014-Dec. 2015 were divided into control group and ob-servation group according to random number table,with 50 cases in each group. Both groups received decongestant Oxymetazoline hydrochloride spray. Control group was additionally given Budesonide spray,once each nostril on the first day,twice each nostril on the second day,increasing suitably according to disease condition,less than 6 times a day for patients younger than 14 years old,less than 8 times a day for patients older than 14 years old;observation group was additionally given Fluticasone furoate nasal spray,once each nostril,qd for patients younger than 14 years old,once each nostril,while morning and night for patients older than 14 years old. Both groups received treatment for consecutive 30 d. The total nasal symptoms score(TNSS),total eye symp-toms score (TESS),total nasal resistance (TNR) under 75,150 Pa,nasal minimum cross-sectional area (MCA) and the occur-rence of ADR were compared between 2 groups before and after treatment. RESULTS:There was no statistical significance in above indexes between 2 groups before treatment (P>0.05). After treatment,TNSS of 2 groups and TESS of observation group were decreased significantly compared to before treatment,and TESS of observation group was significantly lower than that of con-trol group,with statistical significance (P0.05). TNR of 2 groups under 75,150 Pa were significantly lower than before treatment,and the observation group was lower than the control group,with statistical significance (P0.05). The incidence of ADR in observation group was significant-ly lower than control group,with statistical significance(P<0.05). CONCLUSIONS:Fluticasone furoate is similar to budesonide in the treatment of nasal symptoms of AR patients,but it is better than budesonide in improving eye symptoms and nasal ventila-tion function with milder ADR.
RESUMO
BACKGROUND:Polytetrafluoroethylene (PTEE) as a nose filer material has advantages on the resistant to corrosion, chemical stability and so on. However, its linear expansion coefficient is large easily leading to infection and rejection, and its application has some limitations. OBJECTIVE:To compare the cel toxicity, inflammatory infiltrates and biocompatibility indexesin vivo between PTEE and PTEE combined with type Ⅰ colagen. METHODS: MTT method was used to detect the relative proliferation rate of L929 cels cultured with PTEE extract or PTEE combined with type Ⅰ colagen extract; an electron microscope was used to observe the cel growth. PTEE or PTEE combined with type Ⅰ colagen was embedded under the nasal dorsal fascia of New Zealand white rabbits for 7 days, and hematoxylin-eosin staining was used to detect whether nasal mucosa epithelial tissue had inflammatory infiltration. Systemic toxicity, alergies, pyrogen reaction and deaths of rabbits were observed after injection of two kinds of material extracts by ear vein. RESULTS AND CONCLUSION: The cytotoxicity and inflammatory infiltration were milder in PTEE combined with type Ⅰ colagen group than PTEE group (P < 0.05). The alergic reactions and pyrogen reactions were fewer in PTEE combined with type Ⅰ colagen group than PTEE group (P < 0.05). These findings indicate that PTEE combined with type Ⅰ colagen as the nose filer material has better biocompatibility.
RESUMO
OBJECTIVE@#To evaluate the effect of aural/oral rehabilitation in the prelingual deaf children with cochlear implants, analyze the relationship between the age at the time of surgery and the rehabilitation effect, and explore the law of aural/oral rehabilitation in the prelingual deaf children after cochlear implantation.@*METHOD@#Prelingual deaf children with cochlear implants were divided by age into 1.3-2.9 group (17 cases), 3.0-4.9 group(14 cases)and 5.0-7.9 group (26 cases). All the children were evaluated by CAP and SIR questionnaires 3 months, 6 months, 9 months and 12 months after the surgery.@*RESULT@#The scores of CAP and SIR in different age groups were all increased with time after cochlear implantation. The score of CAP in 1.3-2.9 group rose the fastest, which was lowest at the end of the 3rd month and was highest at the end of the 12th month. There were no differences between the CAP scores of 1.3-2.9 group and 5.0-7.9 group in the later test. The score of SIR rose the fastest in 1.3-2.9 group, which was lowest at the end of the 3rd month and highest at the end of the 12th month and rose the slowest in 5.0-7.9 group, which was lower than the other groups at the end of the 12th month.@*CONCLUSION@#Within one year after cochlear implantation, the younger the age, the better the effect of aural/oral rehabilitation.
