Objective To profile the phenotype and pathogens of cutaneous and mucous mycoses in a dermatology outpatient clinic in Nanchang region. Methods A review was performed to assess cutaneous and mucous mycoses diagnosed in the dermatology outpatient clinic of Dermatology Hospital of Jiangxi Province from 2006 to 2008. The relationship of clinical phenotype and pathogens to season, patients' age and gender was analyzed. Results A total of 7251 cases were collected, and the ratio of male to female patients was 2.3: 1. The most prevalent mycoses included tinea cruris (2702, 37.1%), pityriasis versicolor (1505, 20.8%) and tinea manus (727, 10.0%). In total, 4953 fungal strains were isolated from all the patients except for those with pityriasis versicolor, of them, Trichophyton rubrum accounted to 69.9%, Candida to 20.4%, and Trichophyton violaceum to 4.5%. Season, patients' age and gender were found to be associated with clinical phenotypes and pathogens of mycoses. Conclusions In the dermatology outpatient clinic of Nanchang region, tinea cruris is the most common superficial fungal disease, with the predominant pathogen being Trichophyton rubrum. Trichophyton violaceum is the primary pathogen of tinea capitis, which is different from other reports.

Objective To study the clinical efficacy of caffeine in premature infants receiving mechanical ventilation and related complications .Method From January 2014 to September 2016, preterm infants (28w≤GA<33w) treated with nasal continuous positive airway pressure (NCPAP) or conventional mechanical ventilation ( CMV ) in neonatal intensive care unit were studied .They were randomly assigned into the caffeine group and the control group .The caffeine group received caffeine when NCPAP ventilation was applied or adjusting to synchronized intermittent mandatory ventilation ( SIMV) mode.The control group was injected with 5%glucose without caffeine .The t test andχ2 test were used to analyze the clinical efficacy and related complications .Result A total of 96 patients receiving NCPAP ventilation were collected ( birth weight between 1300~2100 g), including 51 cases in caffeine group and 45 cases in the control group. 84 cases received CMV ventilation (birth weight between 1000~1499 g), with 43 cases in the caffeine group and 41 cases the control group.Among the NCPAP infants, the incidence of failure to withdraw ventilator (0% vs.13.3%) and the incidence of bronchopulmonary dysplasia (3.9% vs.17.8%) were lower in the caffeine group than the control group .The duration of assisted ventilation and hospital stay in the caffeine group were shorter than the control group [(6.2 ±3.1) d vs.(8.2 ±3.2) d, (16.3 ±8.7) d vs. (19.5 ±9.2) d], the differences were statistically significant (P<0.05).Among the CMV infants, the incidence of failure of A/C to SIMV mode transition and bronchopulmonary dysplasia were lower in the caffeine group than the control group and the duration of assisted ventilation and hospital stay were shorter . The differences were statistically significant ( P <0.05 ) . No differences were found in the related complications in each group ( P>0.05) . Conclusion Caffeine can help reduce the incidences of withdrawal failure, bronchopulmonary dysplasia , ventilation duration and hospital stay when using NCPAP and CMV ventilation.
