The female reproductive system is essential for sustaining reproductive endocrine homeostasis,however,its vulnerability to various endogenous and exogenous insults,including pathological conditions,pharmacological agents,genetic predispositions,and environmental factors,often results in compromised fertility.The existing protective approaches(including surgical interventions,hormonal replacement therapies,and assisted reproductive techniques)are constrained by several limitations,such as adverse therapeutic effects,technical complexities,and their incapacity to reverse ovarian senescence.Artemisinin and its derivatives(ARTs),characterized by their unique endoperoxide bridge configuration,have exhibited outstanding therapeutic performance across multiple domains including malaria treatment,anticancer therapy,inflammation modulation,and parasitic infection control.Emerging research has identified their novel protective capabilities against various reproductive system pathologies.This comprehensive review systematically elucidates the molecular mechanisms underlying artemisinin-based interventions in reproductive pathologies and evaluates their clinical translation prospects,thereby proposing innovative strategies for the development of next-generation fertility-protective agents with enhanced safety and efficacy profiles.

Objective To evaluate the prognosis of infants with common Hirschsprung's disease who undergo laparoscopic-assisted Soave procedure below 6 months of age,and to explore its feasibility.Methods A retrospective analysis was conducted on the clinical data of 82 cases of common Hirschsprung's disease admitted to our department from January 2018 to August 2022.The patients were divided into two groups based on their age at the time of surgery:Young surgical age group(＜6 months,50 cases)and Old surgical age group(≥ 6 months,32 cases).All patients underwent the treatment of laparoscopic-assisted Soave procedure.The surgical time,length of hospital stay,postoperative complications,and anal function were compared between the two groups.Results There were no significant differences between young surgical age group and old surgical age group in terms of surgical time[(145.04±11.21)min vs.(149.25±12.18)min,P=0.20],length of hospital stay[(13.56+0.93)d vs.(13.91±0.99)d,P=0.55],postoperative complications[22.00％(11/50)vs.28.13％(9/32),P=0.53],and Rintala score for anal function[(18.58±1.44)vs.(17.22±1.64),P=0.06].The main postoperative complications,including enterocolitis[10.00％(5/50)vs.12.50％(4/32),P=0.72],fecal/anal incontinence[6.00％(3/50)vs.6.25％(2/32),P=0.96],and constipation[4.00％(2/50)and 6.25％(2/32),P=0.65],showed no significant differences between the two groups(all P＞0.05).However,there was a statistically significant difference in terms of bleeding volume[(7.86±2.02)ml vs.(9.13±2.17)ml,P＜0.05].No deaths occurred in this study.Conclusion Laparoscopic-assisted Soave procedure is safe and effective for infants below 6 months of age with common congenital Hirschsprung's disease.It can achieve satisfactory anal function and reduce the incidence of adverse events during the waiting period for surgery.

Objective:To analyze the changing trends and area specific differences in influenza vaccination coverage in key populations in Shandong Province and provide evidence for influenza prevention and control.Methods:The information about influenza vaccination in Shandong during 2015 to 2024 were collected from the Immunization Information System of Shandong Province, and the annual percentage change and average annual percentage change (AAPC) were calculated by using software Joinpoint 5.3.0. The trend of changes in vaccination coverage was analyzed and area specific differences were compared.Results:From 2015 to 2024, the influenza vaccination coverage in medical personnel ranged from 0.02% to 20.54% in Shandong (AAPC=63.24%, 95% CI: 51.37%-100.65%), showing a rapid increase from 2015 to 2020 ( P<0.001) and a stead decrease from 2020 to 2024 ( P=0.008). The vaccination coverage in teachers and students ranged from 1.51% to 6.88% (AAPC=12.33%, 95% CI: -0.97%-36.27%), with a monotonic increase from 2015 to 2024 ( P=0.070). The vaccination coverage in elderly people aged ≥60 years ranged from 0.03% to 11.68% (AAPC=102.65%, 95% CI: 64.16%-208.69%), with a rapid increase from 2015 to 2017 ( P<0.001), a steady increase from 2017 to 2020 ( P<0.001), and a slower increasee from 2020 to 2024 ( P=0.046). There were area speciific differences in the temporal trend of influenza vaccination coverage. Compared with areas with low gross domestic product (GDP), the areas with high and medium GDP had significantly higher vaccination coverage and increase rates. Conclusions:The influenza vaccination coverage in key populations showed an upward trend in Shandong from 2015 to 2024, and the vaccination coverage in elderly people aged ≥60 years increased significantly. However, it is important to increase vaccination coverage in areas with low GDP and in teachers and students.

Objective: To analyze the institutional and regional differences in influenza vaccination for teachers and students, so as to provide a basis for influenza prevention and control in campus. Methods: Influenza vaccination data for teachers and students in Shandong Province from 2015 to 2024 were collected from Immunization Information Systems. Joinpoint regression models were used to calculate the annual percent change (APC) and average annual percent change (AAPC) in first-dose vaccination rates. Results: The vaccination coverages for the first dose of influenza vaccine among teachers in Shandong Province from 2015 to 2024 were 0.01%, 0.02%, 0.15%, 0.29%, 0.60%, 2.06%, 1.64%, 2.27%, 3.00%, and 2.43%, with a turning point in 2020. For preschools, primary/secondary schools, and higher education institutions, APCs during 2015-2020 were 163.36%, 162.09%, and 174.94%, respectively( P <0.01), declining to 9.53%, 9.92%, and 8.14% during 2020-2024( P >0.05). Corresponding AAPCs were 78.32%, 78.13%, and 81.61%( P <0.01). High, middle, and low GDP regions exhibited APCs of 173.84%, 162.75%, and 136.67% during 2015-2020( P <0.01) and 5.77%, 13.92%, and 11.86% during 2020-2024( P >0.05), with AAPCs of 79.42%, 81.23% , and 69.63%( P <0.01), respectively. Among students, vaccination coverage ranged from 1.59% to 7.20%. Preschool students showed no turning points, with an AAPC of 18.73%( P <0.01). Primary/secondary students had turning points in 2018 and 2022, APCs were -32.59% during 2015-2018( P <0.01), 48.45% during 2018-2022( P <0.01), and -26.25% during 2022-2024( P =0.04), yielding an AAPC of -2.32%( P =0.45). Higher education students had a turning point in 2020, with APCs of 63.27% during 2015-2020( P <0.01) and 4.31% during 2020-2024 ( P =0.77), and the AAPC was 33.79% during 2015-2024 ( P <0.01). High, middle, and low GDP regions for students showed no turning points, with AAPCs of 10.46%( P =0.18), 13.67%( P =0.01), and 10.42%( P = 0.05 ), respectively. Conclusions The influenza vaccination rate among teachers and students in Shandong Province has shown an upward trend from 2015 to 2024, but the overall level is still relatively low. However, continued efforts are needed to enhance health education on influenza and vaccination, to further improve the vaccination rate of teachers and students.

Background In recent years, the increasingly widespread application of nuclear and medical radiation technologies has resulted in a large number of occupational populations exposed to low-dose ionizing radiation (LDIR). At present, there is no consistent conclusion on the effects of long-term exposure to LDIR on the metabolic health of the occupational population. Objective To explore the association between long-term exposure to LDIR and metabolic syndrome (MetS) among medical radiologists. Methods A cross-sectional study was conducted to enroll 6431 medical radiologists who ordered occupational health checkups from January 2022 to December 2023, and basic information such as demographic characteristics, occupational characteristics, lifestyles, and dietary habits was collected through questionnaires. Physical examinations were conducted using a standardized protocol. Individual dose equivalents of occupational external exposure were monitored by dosimeters worn by medical radiologists. Logistic regression model was used for identifying influencing factors of MetS and sensitivity analysis, and restricted cubic spline model was used to explore the dose-response relationship between cumulative effective dose and MetS. Two-stage linear regression was used to evaluate threshold effect of association between cumulative effective dose and MetS. Results The positive rate of MetS was 13.6% (877/6431) among the enrolled 6431 study participants. The logistic regression showed that gender, age, monthly income, body mass index (BMI), cumulative effective dose, and smoking were influencing factors for MetS. The risk of MetS was higher in males (OR=1.511, 95%CI: 1.209, 1.888); using the < 30 years old group as reference, the risk of MetS was higher in the 30-39 years old (OR=1.509, 95%CI: 1.095, 2.079), 40-49 years old (OR=2.214, 95%CI: 1.551, 3.161), and ≥50 years old (OR=3.480, 95%CI: 2.338, 5.181) groups; using the <10000 yuan group as reference, the risk of MetS was lower in the group with a monthly income of 10000-14999 yuan (OR=0.715, 95%CI: 0.582, 0.878); the risk of MetS was higher in the BMI ≥ 24 kg·m⁻² group (OR=7.548, 95%CI: 6.223, 9.156); using the < 0.76 mSv group as reference, the risk of MetS was higher in the cumulative effective dose of 0.76-2.73 mSv group (OR=1.270, 95%CI: 1.017, 1.586); the risk of MetS was higher in the smoking group (OR=1.734, 95%CI: 1.428, 2.107). The results of restricted cubic spline showed that the cumulative effective dose was nonlinearly correlated with MetS (P _{non-linearity}=0.028), with an inflection point of 1.25 mSv. The risk of developing MetS increased by 34.1% for each unit increase in cumulative effective dose up to 1.25 mSv, whereas above 1.25 mSv, the statistical association was not significant. The sensitivity analysis results showed that after excluding the self-reported hypertensive and diabetic patients, the cumulative effective dose 0.76-2.73 mSv group still had an increased risk of developing MetS compared with the < 0.76 mSv group (P < 0.05), and the results were robust. Conclusion Among medical radiologists, male, age, BMI, and smoking are positively correlated with MetS, and monthly income is negatively correlated with MetS; cumulative effective dose is non-linearly correlated with MetS among medical radiologists.
