【Abstract】 Objective To investigate the recent epidemic trends and spatiotemporal distribution characteristics of gonorrhea in China, and to provide a reference for precise prevention and control of gonorrhea. Methods Data on reported cases of gonorrhea in China (not including Hongkong, Macau and Taiwan regions of China) were collected from the Infectious Diseases Surveillance System of Chinese Disease Prevention and Control Information System from 2018 to 2023. The trends in reported incidence rates of gonorrhea in China were analyzed using the Joinpoint regression model. Global spatial autocorrelation analysis with the Moran′s index and global G-statistic, as well as local spatial autocorrelation analysis, were employed to explore the clustering patterns and hotspot regions of gonorrhea at the county level. In the spatiotemporal scanning analysis, a Poisson distribution model was employed to identify clusters of gonorrhea cases. Results The reported incidence rates of gonorrhea in China decreased from 9.59 per 100 000 in 2018 to 7.35 per 100 000 in 2023, with an average annual percent change of -4.9%, but this decreasing trend was not statistically significant (P = 0.11). The reported incidence rates of gonorrhea at the county level in China exhibited a significant positive global spatial autocorrelation, with the global Moran′s indices ranging from 0.39 to 0.60 (all P < 0.001); the Getis-Ord general G test statistic Z(G) values were all greater than 1.96, indicating a high-value clustering pattern of gonorrhea cases. The local spatial autocorrelation analysis showed that hotspot regions were predominantly distributed in southeastern coastal areas and southwestern China. A total of 70 clusters were identified through the spatiotemporal scanning analysis, and mainly located in southeastern coastal areas and southwestern China. Conclusions In recent 6 years, the overall reported incidence rates of gonorrhea in China showed a fluctuating decline; there was a significant spatiotemporal clustering characteristic with regard to gonorrhea epidemic at the county level in China, and the hotspot regions were basically consistent with the spatiotemporal clusters, which were mainly distributed in southeastern coastal areas and southwestern China. Further investigation into the causes and precise prevention and control measures are needed.

【Abstract】 Objective To evaluate the efficacy and safety of omalizumab in the treatment of chronic urticaria in children. Methods A retrospective study was conducted. Patients with chronic urticaria were collected from the Department of Dermatology, Hunan Children′s Hospital from January to December 2021, and divided into a control group and a combination group according to different medication regimens. The patients in the combination group received subcutaneous injections of omalizumab (150 mg, once every 4 weeks) combined with conventional-dosage antihistamines, while the patients in the control group were only treated with double-dosage or multiple types of antihistamines. The course of treatment was 3 to 6 months. The clinical efficacy and adverse reactions were observed at 3, 6, and 12 months after the start of treatment, and the recurrence was observed at 3 and 6 months after the end of treatment. Results A total of 46 children with chronic urticaria were collected. There were 13 males and 10 females in the combination group; they were aged from 6 to 17 years, including 16 aged from 6 to 12 years and 7 aged from 13 to 17 years; according to the total serum IgE levels before treatment, the patients in the combination group were divided into an increased IgE subgroup (11 cases) and a normal IgE subgroup (12 cases). In the control group, there were 13 males and 10 females; they were aged from 6.33 to 16 years, including 15 aged from 6 to 12 years and 8 aged from 13 to 17 years. At 3, 6, and 12 months after the start of treatment, all the total response rates in the combination group were 86.96% (20/23), which were all significantly higher than those in the control group (52.17% [12/23], 56.52% [13/23], 56.52% [13/23], P = 0.010, 0.022, 0.022, respectively). In the combination group, the response rates at 3, 6, and 12 months after the start of treatment were all 14/16 in the children aged 6 to 12 years and 6/7 in those aged 13 to 17 years, and there were no significant differences between the two age groups (all χ2 = 0.01, all P = 0.907); in the control group, the response rates were 5/15, 6/15 and 5/15 respectively in the children aged 6 to 12 years, which were significantly lower than those in the combination group (P = 0.002, 0.006, 0.006, respectively). In the combination group, the response rates at 3, 6, and 12 months after the start of treatment were all 9/11 in the increased IgE subgroup and 11/12 in the normal IgE subgroup, and there were no significant differences between the two subgroups (all P = 0.484). During the treatment, no serious adverse reactions were observed in the combination group and control group, and mild somnolence only occurred in 2 children in the control group. At 3 months after the end of treatment, there was no recurrence in 16 patients in the combination group and 2 experiencing recurrence in 6 in the control group, and the recurrence rate was lower in the combination group than in the control group (P = 0.030) at 6 months after the end of treatment, there was no recurrence in 16 patients in the combination group and 3 experiencing recurrence in 6 patients in the control group, and the recurrence rate was lower in the combination group than in the control group (P = 0.022). Conclusion Omalizumab combined with conventional-dosage antihistamines could improve the clinical efficacy and reduce the recurrence rate in the treatment of chronic urticaria in children, with few adverse reactions.

【Abstract】 Currently, childhood atopic dermatitis (AD) is mainly treated by regular use of moisturisers in combination with topical glucocorticoids or calcineurin inhibitors. For some children with refractory moderate-to-severe AD, systemic glucocorticoids or off-label use of other immunomodulators may be required; however, these treatments usually have some limitations and adverse effects. In recent years, with the discovery of key inflammatory factors in AD, dupilumab, a biological agent targeting interleukin-4/13, has been widely used in clinical practice, and shown certain efficacy. This review summarizes recent clinical studies on dupilumab in the treatment of AD in children.

【Abstract】 The pathogenesis of acne is still unclear. At present, studies have confirmed roles of transcription factors and receptors in the occurrence and development of acne. Toll-like receptors, insulin-like growth factors, androgen receptors are risk factors for acne, while vitamin D receptors, retinoic acid receptors, epidermal growth factors, peroxisome proliferator-activator receptors are protective factors for acne, all of which are expected to be targets for prevention and treatment of acne. This review focuses on recent research progress in acne-related transcription factors and their receptors, in order to provide new directions for targeted therapy of acne.
