Objective: o analyze the epidemic characteristics of five sexually transmitted diseases (STDs), including syphilis, gonorrhea, condyloma acuminatum, genital herpes and genital Chlamydia trachomatis infection in Yangzhou City, Jiangsu Province from 2019 to 2023, so as to provide the reference for the prevention and control strategies of STDs. Methods: Data of the onset time and diagnostic types of STDs cases in Yangzhou City from 2019 to 2023 were collected from the Infectious Disease Surveillance System of Chinese Disease Prevention and Control Information System. The temporal, regional and population characteristics of five types of STDs was analyzed using the descriptive epidemiological method. Results: A total of 10 895 cases of STDs were reported in Yangzhou City from 2019 to 2023, with an average annual reported incidence rate of 47.83/105. The average annual reported incidence rates of syphilis, gonorrhea, condyloma acuminatum, genital herpes and genital Chlamydia trachomatis infections were 41.11/105, 2.83/105, 2.59/105, 0.43/105 and 0.85/105, respectively. The reported incidence rate of STDs showed a decreasing trend from 2019 to 2023 (P<0.05), with an average annual growth rate of -3.44%. The reported incidence rates of syphilis and gonorrhea showed a decreasing trend (both P<0.05), with average annual growth rates of -4.26% and -6.47%, respectively. The reported incidence rate of genital Chlamydia trachomatis infection showed an increasing trend (P<0.05), with an average annual growth rate of 22.32%. Baoying County, Guangling District and Hanjiang District had the top three reported incidence rates of STDs, at 56.61/105, 55.61/105 and 46.50/105, respectively. The average annual reported incidence rate of STDs among males was higher than that among females (53.19/105 vs. 42.54/105, P<0.05). The STD cases were primarily people aged 50 years and above, with 6 641 cases accounting for 60.95%. The occupations of STD cases were mainly farmers, housekeepers and unemployed, with 4 670 and 3 273 cases accounting for 42.86% and 30.04%, respectively. Conclusions The overall reported incidence of STDs in Yangzhou City from 2019 to 2023 showed a downward trend, while the reported incidence of genital Chlamydia trachomatis infection showed an upward trend. The individuals aged 50 years and above, farmers, housekeepers and the unemployed were identified as high-risk groups for STDs.

Objective: To investigate the awareness rate of non-occupational post-exposure prophylaxis (nPEP) for AIDS and its influencing factors among men who have sex with men (MSM) in Yangzhou City, Jiangsu Province. Methods: From January to June 2024, MSM aged ≥16 years in Yangzhou City were recruited using the snowball sampling method. Basic information, sexual behavior characteristics, awareness and usage of nPEP, and awareness of pre-exposure prophylaxis (PrEP) for AIDS were collected through questionnaire surveys. Factors affecting awareness of nPEP among MSM were analyzed using multivariable logistic regression model. Results: A total of 740 participants were enrolled, with a median age of 29 (interquartile range, 14) years. There were 497 participants with a college degree and above educational level, accounting for 67.16%. A total of 541 participants resided in urban areas, accounting for 73.11%. The awareness rate of nPEP was 57.30%. The primary channels for awareness were the internet and healthcare institution promotions, with 159 and 119 participants, accounting for 37.50% and 28.07%, respectively. A total of 57 participants had utilized nPEP, with a usage rate of 7.70%. The main reason for using nPEP was having unprotected sex, with 21 participants, accounting for 36.84%. Multivariable logistic regression analysis revealed that unmarried MSM (OR=2.369, 95%CI: 1.236-4.540) and those who were aware of PrEP (OR=28.067, 95%CI: 17.664-44.597) had a significantly higher likelihood of being aware of nPEP. Conclusions The awareness rate and usage rate of nPEP among MSM in Yangzhou City are both relatively low. Awareness of nPEP is mainly influenced by marital status and whether participants are aware of PrEP.

Objective To analyze the epidemiological characteristics of syphilis in Yangzhou City from 2013 to 2023, to understand the syphilis epidemic trends, and provide a scientific basis for formulating prevention and control strategies. Methods Syphilis case reports in Yangzhou City from 2013 to 2023 were collected through the infectious disease surveillance module of the Chinese Center for Disease Control and Prevention Information System. The annual average reported incidence rate and annual average growth rate were calculated. Descriptive epidemiological methods were employed to analyze the overview of syphilis and its temporal, geographical and demographic distribution characteristics. Linear trend chi-square tests were conducted to analyze the syphilis epidemic trends. Results A total of 19, 457 syphilis cases were reported in Yangzhou City from 2013 to 2023, with an annual average reported incidence rate of 39.17/100, 000. The overall incidence of syphilis showed an upward trend, with the reported incidence rate increasing from 37.26/100, 000 in 2013 to 43.27/100, 000 in 2023 (χ²= 50.528, P < 0.001), representing an annual average growth rate of 1.51%. The majority of reported cases were latent syphilis, accounting for 64.99% (12, 646/19, 457). The number of reported cases of primary, secondary and congenital syphilis revealed an overall decreased trend, while the number of reported cases of tertiary and latent syphilis increased trend. There was no significant seasonality or periodicity in the reported incidence rate of syphilis in Yangzhou City from 2013 to 2023. The top three districts with the highest annual average reported incidence rates were the Development District, Guangling District and Hanjiang District, with incidence rates of 50.93/100, 000, 50.89/100, 000 and 43.18/100, 000, respectively. There were 10, 290 male syphilis cases (52.89%) and 9, 167 female syphilis cases (47.11%). The top three occupations were farmers (8, 682 cases), homemakers and unemployed individuals (5, 379 cases) and retired personnel (2, 559 cases), accounting for 85.42% (16, 620/19, 457) of the reported cases. Conclusion The incidence of syphilis in Yangzhou City generally shows an upward trend, and the disease epidemic spectrum changes annually, with latent syphilis currently being the primary form. The prevention and control situation is severe. Therefore, syphilis prevention and control efforts should be further strengthened to block its transmission and prevalence.

Objective:To explore the effect of perineal lateral incision and continuous suture of deep and superficial Ⅱdegree laceration on postoperative perineum rehabilitation of parturients.Methods:Randomized controlled trials of intervention effects on postoperative maternal wound rehabilitation using continuous sutures and interrupted sutures of mucosal, muscle, and skin layers after perineal lateral resection and Ⅱdegree lacerations were searched in Cochrane Library, PubMed, Medline, Embase, Science direct, China Biology Medicine, China National Knowledge Infrastructune, Wanfang Database, VIP Database. The retrieval time limit was from database establishment to October 1, 2020. using RevMan 5.3 software for statistical processing.Results:After searching and screening, 12 articles were finally included. The total sample size was 2 827 cases. After the two groups used different suture techniques, the results of Meta analysis showed that the pains ( MD=1.02, 95% CI=1.02-1.06), the suture time ( MD=-4.59, 95% CI=-7.29 - -1.91) and the healing condition ( MD=-0.55, 95% CI=-0.71 - -0.39) of the two groups were compared, the differences were significant (all P<0.01). Conclusions:In the suture of perineal lateral incision and Ⅱdegree laceration, continuous suture technique is used to suture the mucosal layer, muscle layer, and cortex, which can reduce the suture time, reduce the pain of the parturient, and is beneficial to the healing of the wound. It can be clinically based on the parturient. It can be used in accordance with the neatness and depth of the mouth and the needs of the parturient.
