OBJECTIVE To compare two administration methods of triamcinolone acetonide cream for the treatment of ear mycosis with pevison. METHODS Eighty-six cases diagnosed as the external auditory canal fungal infections with tympanic membrane perforation were randomly divided into observation group and control group, with 43 cases in each group. All the selected patients were positive in the external auditory meatal secretions fungus detection test, fungi and secretions of the external auditory canal are thoroughly cleaned under the endoscope. After ear canal cleaning, the obervation group was treated with Pevisone smeared on gelatin sponge which was evenly placed on the external auditory canal with fungal infection. The control group was treated with Pevisone smearing on external auditory canal by the patients themselves, twice a day. Two groups of patients come to the hospital every 3 days for review. After 2 weeks of treatment, the patients were followed up for 3 months, and the clinical efficacy of each group was compared. RESULTS The observation group was cured in 39 cases(90.7％), effective in 2 cases(4.7％), and ineffective in 2 cases(4.7％), The total efficiency rate is 95.3％.1 case recurred at 3 months of follow-up(2.4％). While in the control group, it was cured in 26 cases(60.5％), effective in 1 cases(2.3％), and ineffective in 16 cases(37.2％), the total efficiency rate is 62.8％.9 cases recurred at 3 months of follow-up(31.0％). The effect of the observation group was significantly higher than that of the control group(x2=14.508, P<0.05). CONCLUSION The ear endoscope can be used to remove the external auditory canal fungus thoroughly and has good visibility. Treating external auditory canal fungi disease with tympanic membrane perforation with gelatin sponge coated with triamcinolone acetonide cream has better clinical efficacy.

Their structures were identified on the basis of physicochemical properties and spectral data as gleditsioside A(1), gleditsioside B(2), gleditsioside H(3), gleditsioside I(4), gleditsioside J(5), gleditsioside K(6), gleditsia saponins C′(7), tamarixetin-7-O-β-D-glucopyranoside(8), neohesperidin(9), chrysoeirol-7-O-neohesperidoside(10); syringaresinol- O-β-D-glucopyranoside(11), liriodendrin(12). Compounds 8-12 were firstly isolated from this genus.

Twelve compounds were isolated and purified from ethyl acetatefraction of Cynanchum stauntonii by silica gel, Sephadex LH-20 and ODS column chromatography. Their structures were identified by spectral techniques and physicochemical properties as syringaresinol(1), (-)-(7R, 7′R, 7″R, 8S, 8′S, 8″S)-4′, 4″-dihydroxy-3, 3′, 3″, 5-tetramethoxy-7, 9′ ∶7′, 9-diepoxy-4, 8″-oxy-8, 8′-sesquineolignan-7″, 9″-diol(2), prinsepiol(3), 4-hydroxyacetophenone(4), baishouwubenzophenone(5), 2, 4-dihydroxyacetophenone(6), benzoic acid(7), 1, 4-benzenediol(8), 6-O-［E］-sinapoyl-α-D-glucopyranoside(9a), 6-O-［E］-sinapoyl-β-D-glucopyranoside(9b), 1-O-methyl-α-D-cymadropyranoside(10), β-daucosterol(11), and β-sitosterol(12). Compounds 1-3, 5 and 7-11 were firstly isolated from this plant.

ObjectiveTo investigate the prevalence of Staphylococcus aureus in patients with diarrhea, and to analyze the genes carriage of enterotoxin in the strains of these patients in Jiading District, Shanghai. MethodsFrom 2021 to 2023, anal swabs of diarrhea outpatients from one sentinel hospital and nine community health service centers in different townships in Jiading District, Shanghai, were tested for Staphylococcus aureus, from which five enterotoxin virulence genes such as SEA, SEB, SEC, SED, and SEE were tested simultaneously. ResultsA total of 1 080 anal swabs were collected, 81 of which were tested positive for S. aureus, with a detection rate of 7.50%, and the detection rate of S. aureus was similar in patients with diarrhea from 2021‒2023. There was no statistically significant difference in detection rates between males and females (χ²=0.821, P=0.365). S. aureus detection rate was highest in infants and young children with diarrhea (29.51%), followed by 14.06% in the people aged between 4‒<31 years, and 2.99% in those aged ≥31 years. Significant differences were observed in the detection rate of S. aureus in the diarrhoeal patients from different townships of Jiading District(χ²=66.134,P<0.05). The carriage rates of the 5 enterotoxin genes, namely SEA, SEB, SEC, SED, SEE, were 13.58%, 14.81%, 11.11%, 7.41%, and 0, respectively. ConclusionThe prevalence of S. aureus among the patients with diarrhea in Jiading District is relatively stable but with distinct geographical patterns. Children and adolescents are high-risk groups. SEB were the dominant gene, followed by SEA.

Objective To analyze the distribution of common allergens in children with allergic rhinitis(AR)in Hangzhou,and to provide reference for its prevention and treatment.Methods From January 2020 to December 2022,13 521 children who were diagnosed with AR and underwent in vitro serum specific immunoglobulin E(sIgE)detection in Affiliated Hangzhou First People's Hospital,School of Medicine,Westlake University were selected as the research objects.The positive rates of allergens in children with AR of different genders,ages and seasons were compared.Results Among 13 521 children,the positive rate of sIgE was 54.49%(7367/13 521),of which 64.82%were allergic to only one allergen.Among the 19 common allergens,the top three overall positive rates were household dust mite(44.27%),milk(14.62%),and mixed grass(4.82%).The positive rates of allergens of house dust mites,cat hair dander,mulberry,mold combination,tree pollen combination,amaranth,cockroach,milk,shrimp,crab,pineapple,shellfish and mango in male children were significantly higher than those in female children(P<0.05).The positive rates of allergens of house dust mite,mixed grass,cat hair dander,mulberry,mold combination,egg white,shrimp,crab,pineapple,cashew nuts and shellfish in different age groups were statistically significant(P<0.05).July and August were the two months with the highest allergen positive rate.The allergen positive rates of house dust mite,dog and cat hair dander were the highest in summer,and the allergen positive rate of plants was consistent with the flowering season.The sIgE concentration of house dust mite(77.87%)was mainly grade 3 and above.The sIgE concentration of other allergens was mainly grade 1 and 2.Conclusion Dust mites and milk are the most common allergens in children with AR in Hangzhou,and the distribution of allergens varies with gender,age and season.Allergen detection can provide a more accurate plan for the diagnosis,prevention and treatment of AR.
