    Abstract The aim of this study was to analyze the epidemiological characteristics and pathogen spectrum of tinea capitis in Guangxi, southern China. A multicenter prospective descriptive study was conducted in 8 hospitals across Guangxi. From January 2019 to July 2022, one hundred seventy-one (171) patients diagnosed with tinea capitis were included. Demographic data, risk factors, and fungal data were collected. If necessary, species were further identified by morphological or molecular sequencing in the central laboratory. Of the 171 cases of tinea capitis, 74.3% occurred in patients aged 2-8 years. Children with tinea capitis were mainly boys (59.6%) and were more likely than adults to have a history of animal contact (44.2% vs. 33.3%) and zoophilic dermatophyte infection (76.9% vs. 46.7%, P = 0.008). The adults were mainly female (53%) and were more likely than children to have a history of infection with anthropophilic organisms (53.3% vs. 18.9%). The causative agents of tinea capitis in Guangxi were diverse, and the most common pathogen was Microsporum canis (M. cani, n = 98, 62%), followed by Trichophyton mentagrophytes (T. mentagrophytes n = 18, 11.4%) and Trichophyton tonsurans (T. tonsurans n = 12, 7.6%). In addition, tinea capitis caused by Nannizzia incurvata (N. incurvata) and Trichophyton verrucosum (T. verrucosum) was detected in the study. Notably, the proportion of patients with kerion in the study was 41.5% (n = 71), and most of those patients were children (n = 68), especially neglected children living in the rural mountainous areas of Guangxi, where they were unable to receive timely diagnosis and appropriate treatment. In conclusion, the causative agents of tinea capitis in Guangxi, South China, are diverse, and the incidence of kerion is high, indicating that diagnosis and treatment modalities in the region remain grossly inadequate. Clinicians and policy-makers should collaborate to adopt public health strategies to control the disease.

    Abstract Objective: To explore the association of the Thr241Met polymorphism of X-ray cross-complementing group 3 (XRCC3) gene with genetic susceptibility to aflatoxin B1(AFB-1)-related hepatocellular carcinoma (HCC)in Guangxi population.
    Methods: We conducted a hospital-based case-control study, including 257 HCC cases and 711 controls without cancers or liver diseases. The XRCC3 Thr241Met polymorphism was analyzed by PCR.
    Results: The XRCC3 genotypes XRCC3-Thr/Met or XRCC3-Met/Met were related with an elevated risk of HCC. The risk of HCC was associated with the number of mutant Met copies (adjusted OR were 2.20 and 8.56 for XRCC3-Thr/Met and Met/Met, respectively); moreover, there seemed to be combined effects for HCC risk between the variant genotypes and AFB1-DNA adduct levels from peripheral blood leukocytes (adjusted OR was 2.34 to 20.44, P < 0.01).
    Conclusion: These results suggested that XRCC3 polymorphism may be associated with the risk of AFB1- related HCC among the Guangxi population, and interacts with AFB1 exposure in the development of HCC induced by AFB1.
