Objective:This study aims to investigate the relationship between high-risk human papillomavirus (HR-HPV) infection and the composition of vaginal microecology. It will analyze the efficacy of integrated traditional Chinese and Western medicine intervention in treating HR-HPV infection, as well as the effects of this combined approach on vaginal microecology. Additionally, the study seeks to identify new methods to inhibit the malignant progression of cervical intraepithelial lesions.Methods:A prospective study was conducted involving 100 patients with HR-HPV infection who visited the Department of Gynecology, The Second Affiliated Hospital of Shaanxi University of Chinese Medicine from April to June 2023. The participants were randomly divided into a control group and an observation group, with 50 patients in each group using a random number table method. The control group received interferon treatment, while the observation group was treated with a combination of interferon and Yanfukang Lotion. High-throughput DNA sequencing of vaginal secretions was conducted to compare the differences in pre- and post-treatment vaginal microecological composition and the rate of HR-HPV clearance between the two groups. Results:In the observation group, both the diversity index and the abundance of vaginal microecology showed significant improvements compared with the control group, particularly in the abundance of dominant Lactobacillus species. These differences were statistically significant ( R = 0.124, 0.304, 0.030, all P < 0.05). The rates of HR-HPV clearance and overall effective rate (clearance + effective) in the observation group were 44% (22/50) and 68% (34/50), respectively, which were significantly higher than those in the control group [20% (10/50), 32% (16/50), χ2 = 12.98, both P < 0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (χ2 = 1.76, P > 0.05). Conclusion:The combination of interferon and Yanfukang Lotion effectively treats HR-HPV infection by regulating the composition of vaginal microecology. This approach shows considerable efficacy and good safety, indicating its potential for further clinical application.

OBJECTIVETo investigate the changes of epidemiological characteristics of measles in Beijing before and after Supplementary Immunization Campaigns (SIA) (2007-2010 vs 2011-2014) of measles-containing vaccine (MCV) among children aged between 8 months and 14 years in 2010.

METHODSDescriptive epidemiological analysis was conducted on surveillance data of measles cases (clinical cases and laboratory confirmed cases), with the occurrence during 2007-2014, and of outbreaks, with the occurrence during 2009-2014, from National Notifiable Disease Reporting System. MapInfo geographic information system (Version 8.5) was used to illustrate the distribution of measles incidence by district. Annual measles incidence was classified into 5 groups at the same intervals between the upper and lower limits to analyze the morbidity of the different areas.

RESULTSIn total, 7 722 and 3 132 measles cases were reported during 2007-2010 and 2011-2014, with the annual incidence of 11.59 and 3.84 cases per 100 000 population, respectively. Comparing with the results during 2007-2010, total number of measles cases and average annual incidence during 2011-2014 were decreased by 59.4%, and 66.9%, respectively. Among measles cases during 2011-2014, percentage of cases aged 15 years or above were 57.7%(56/97), 62.0%(49/79), 65.5%(370/565), and 71.4% (1 707/2 391), respectively, which increased by years. During 2007-2010, the highest risk age for adults was 20-34, while 2011-2014, 5 years older: 25-39. During 2009-2010, 2011-2012, and 2013-2014, 50.3% (447/889), 30.3% (10/33), and 57.8% (201/348), respectively, of measles cases aged 8-17 months were unvaccinated by MCV. Percentages of measles cases aged 0-7 months, 8 months-14 years, 15-39 years and 40 years or above during 2013-2014, who visited hospitals 7-21 days before disease onset, were 59.8% (238/398), 49.3% (237/481), 32.2% (529/1641), and 37.6% (164/436), respectively. A total of 11 nosocomial measles outbreaks occurred during 2013-2014, which was much higher than that during 2009-2010 (2 nosocomial outbreaks). And universities accounted for the majority of outbreak settings of schools (3/4). All 11 outbreaks among grouped employees during 2009-2012 occurred in factories, restaurants, or large shopping centers, while the largest proportion (6/16) of that kind of outbreaks during 2013-2014 occurred in office buildings.

CONCLUSIONSSIA of MCV in 2010 effectively decreased measles transmission in Beijing. But routine immunization of MCV still needed to be improved. The issue of adult measles has been a prominent problem. Hospitals, office buildings and universities were the focus of prevention of measles transmission.
