ABSTRACT
Objective To observe the nasal flush combined budesonide suspension liquid atomizing inhaled treatment of allergic rhinitis in infants,explore the allergic rhinitis treatments in infants. Methods 137 cases diagnosed as allergic rhinitis were collected and randomly divided into 70 cases as the treatment group and 67 patients as the control group. The patients in control group were washed the nasal cavity with 2.8% warm sodium chloride solution using 50ml and 0.5% metronidazole injection 30ml by turn. At the first week, 1 time/d, then one time every other day,while according to age,body mass the patients were given to loratadine, 1 time/d. Treatment group were used budesonide nasal inhalation of 1 ml at the base of treatment of the control group. Before and after the treatment , nasal congestion,sneezing, flow clear nose, sleep snoring and sleep quality score index were observed and compared.Results 70%of the treatment group the nasal congestion,sneezing,flow clear in 3 times after treatment with ease.The children sleep quality improved and the snoring fewer over night,only 56.7% of the control group of these symptoms improved. After the treatment the efficiency evaluation of treatment group and control group respectively was 95.1% and 77.7% ,there was statistically significant difference( x2 =9.83 ,P ＜0. 01 ). 137 cases of patients without a side effects. Conclusion curative effect of nasal flush combined budesonide suspension liquid nasal spray inhaled treatment of allergic rhinitis was distinct,infant effect-acting quickly,without side effects,easy to use.
ABSTRACT
Objective To observe the expression of tumor necrosis factor-α(TNF-α)in acute lung injury caused by paraquat(PQ)in rats,and investigate the mechanism of the rhubarb in respect of pmteetive effects.Method PQ intragastrically poisoning at the dose of 50 mg/kg made a model of the acute lung injury in Sprague-Dawley(SD)rats.Totally 144 adult healthy SD rats(72 female,72male)were randomly divided into control group (group A,n=24),poisoned group(group B,n=48),rhubarb treated group(group C,n=48)and the shaln poisoning group(group D,n=24).Rats of group B and group C were poisoned intmgastrically with PQ(50 mg/kg).and rats of group C and group D were intervened intragastrieally with 300 mg/(kg·d)of rhubarb in 15 min-utes.The white blood cells and total cells in bronchoalveolar lavage fluid(BALF)were counted by using a blood cell counting plate and the protein content of BALF was measured by using the way of Lowry in order to calculate the neutmphiks pereentage and lung permeability index.A small portion of left lung was stained with HE to observe the pathological changes and the expression oftumor necrosis factor-α in the rest of the left lung was observed with immunohistochemistry.The data were handled by the analysis of variance and NK method using SPSS 14.0.Re-suits Compared with group A,the lungs of rats mainly showed congestion,edema and leukocytes infiltration in group B,and fibrosis was found onlyt in a few rats.And the rate neutrophils percentage,protein content and lung permeability index in BALF increased(P＜0.01).The expression of TNF-α were obviously inereased at 12 hours after PQ poisoning,and immtmohistochemistry score (IHS)was higher,and peaked at 24 hours later(P＜0.05),then remained on a high level for a while and sluggishly declined.Compared with group B,the changes of above mentioned were alleviated obviously,and the expression of TNF-α delayed with the less magnitude of increasing an an obvious tendency of less expression.Compared with group B,delayed,lower increasing extent,obviously re-ducing tendency in group C with statistical difference in IHS(P＜0.05).Conclusions Rhubarb ameliorates a-cute lung injury caused by PQ poisoning in rats by means of inhibiting the expression of TNF-α in turn to alleviate inflammatory reaction.
ABSTRACT
OBJECTIVE@#To study the diagnostic value of high-resolution computed tomography (HRCT) and multiplanar reconstruction (MPR) in assessment of semicircular canals disease.@*METHOD@#Eighty-three patients were scanned with HRCT and the original data were processed with MPR. The semicircular canals full length was respectively observed in one image of MPR in the normal ears. The abnormal location of the canal were observed.@*RESULT@#In one image the full length of the horizontal, superior and posterior semicircular canal can be respectively displayed in one image of MPR in normal ears. By this way ,1 superior semicircular canal dehiscence (SSCD)was found in precaution group, 1 superior and 2 horizontal semicircular canal blocked, 1 vestibular aqueduct (VA) joined into superior semicircular canal and 2 VAs joined into posterior semicircular canal and abnormity of the three semicircular canals were found in SNHL.@*CONCLUSION@#MPR canould display the three canals full length in one picture and have a high specificity in the diagnosis of the semicircular canal abnormity.

OBJECTIVE@#To observe the inner ear structure with volume rendering (VR) reconstruction and to evaluate the role of high-resolution computed tomography (HRCT) in congenital inner ear malformations.@*METHOD@#HRCT scanning was performed in 10 patients (20 ears) without ear disease (control group) and 7 patients (11 ears) with inner ear malformations (IEM group) and the original data was processed with VR reconstruction. The inner ear osseous labyrinth structure in the images generated by these techniques was observed respectively in the normal ears and malformation ears.@*RESULT@#The inner ear osseous labyrinth structure and the relationship was displayed clearly in VR imaging in the control group,meanwhile, characters and degree of malformed structure were also displayed clearly in the IEA group. Of seven patients (11 ears) with congenital inner ear malformations, the axial, MPR and VR images can display the site and degree in 9 ears. VR images were superior to the axial images in displaying the malformations in 2 ears with the small lateral semicircular canal malformations. The malformations included Mondini deformity (7 ears), vestibular and semicircular canal malformations (3 ears), vestibular aqueduct dilate (7 ears, of which 6 ears accompanied by other malformations) , the internal auditory canal malformation (2 ears, all accompanied by other malformations).@*CONCLUSION@#HRCT can display the normal structure of bone inner ear through high quality VR reconstructions. VR images can also display the site and degree of the malformations three-dimensionally and intuitively. HRCT is valuable in diagnosing the inner ear malformation.
