Objective To compare the application of Goldman , CARPREG and ZAHARA in predicting cardiac outcomes in pregnant women with congenital heart disease. Methods A retrospective analysis of 144 pregnant women with CHD , enrolled in The Third Affiliated Hospital of Guangzhou Medical University between Jan 1992 and June 2015 was conducted. The mortality and the incidence of cardiac events were counted by three risk estimation methods. The sensitivity and calibration of three systems were compared by using Hosmer-Lemeshow goodness of-fit analysis and Aera Under Curve (AUC). Results In terms of mortality rates, the sensitivity of CARPREG was higher than that of Goldman (AUC:0.874 and 0.889 respectively;P = 0.568 >0.05);. In terms of the incidence of cardiac events, the sensitivity of ZAHARA was higher than that of Goldman (AUC:0.912 and 0.773 respectively;P = 0.063 > 0.05); Conclusions All 3 risk estimation methods have good performance in sensitivity of predicting the incidence of cardiac events and mortality in pregnant women with CHD. The ZAHARA has a better calibration in predicting the incidence of cardiac events , and we recommend ZAHARA as the first choice of evaluation system for this kind of patients.

Objective To research the relationship between free/total prostate specific antigen (f/t PSA), PSA density(PSAD) and prostate cancer(PCa), to explore healthy middle and old-aged,the patients with BPH, the scope of reference value of PSA,frce PSA(fPSA), f/t PSA and PSAD in patients serum with PCa. Methods To de-tect 307 cases of healthy gerontism male,236 of BHP and 41 of PSA and fPSA in patients with PCa,to calcuLate f/t PSA and PSAD, to investigate the dependability between PSA ,I"PSA ,f/t PSA ,P SAD and healthy male, the patients ofBHP,the PCa ,to determine the scope of reference value PSA,fPSA,f/t PSA and PSAD fitting for Chinese. Results PSA and fPSA in patients with PCa are obviously higher than normal control(P <0.01). f/t PSA is obviously lower than the BPH and normal control(P < 0.01). When PSA is 9.25 and f/t PSA is 20%, there are better value of clini-cal diagnosis,when PSAD is 0.18 (AUC = 0.635), we can get best aceuration of diagnosis. Conclusions f/t PSA and PSAD are better than PSA in clinical diagnosis. When PSA is more than 9.25,f/t PSA is less than 20% or PSAD is more than 0.18 is significance for diagnosis. The normal reference value of PSA less than 9.25,f/t PSA more than 20%, PSAD less than 0.18 is fit for Chinese.

Abstract: Objective To investigate the clinical types of children's tinea capitis and the distribution of fungal pathogens in Wuhan from 2011 to 2020, and to provide scientific basis for the prevention, diagnosis and treatment of children's tinea capitis. Methods Laboratory data of children with tinea capitis in outpatient and inpatient department of dermatology in Wuhan No.1 Hospital from January 2011 to December 2020 were collected. A total of 542 cases of pediatric tinea capitis were included, with 239 male cases and 303 female cases. Microscopic examination of fungi and culture identification were performed on the affected skin lesions of the children. Chi-square test was used to analyze the differences in pathogen spectrum of children with different age groups and clinical type. Results Among the pediatric tinea capitis patients, the age group with the highest prevalence was preschool children（3 to <7 years old), accounting for 48.52%（263/542). The top three pathogenic fungi were Trichophytes violaceum（49.26%, 267/542), Microsporum canis（31.55%, 171/542) and Trichophyton mentagrophytes （9.96%, 54/542). Trichophyton violaceum was the main pathogen in all ages, followed by Microsporum canis. The infection rate of Microsporum canis in children over 7 years old was lower than that in children under 7 years old, and the infection rate of Trichophyton rubrum in infants was higher than that in other ages. The distribution of Trichophytes violaceum, Trichophyton mentagrophytes, Nannizzia gypseum and Microsporum ferrugineum was uniform in all age groups. Trichophytes violaceum and Trichophyton tousurans mainly caused black-dot ringworm, Microsporum canis mainly caused tinea alba, Trichophyton mentagrophytes,Nannizzia gypseum and Trichophytonrubrum mainly caused kerion. Except for Microsporum ferrugineum, the composition ratios of other fungi species showed statistically significant differences among different clinical types of tinea capitis（P<0.05). Conclusions Preschool children are the most commonly affected age group by pediatric tinea capitis, and black-dot ringworm caused by Trichophytes violaceum is the main clinical type. Analysis of the high-riskage group, pathogenic fungi and clinical types of tinea capitis in children can enhance the understanding of its epidemiological characteristics, which is helpful for early diagnosis and targeted standardized treatment of pediatric tinea capitis.
