Objective: To explore the longitudinal association between weight trajectories and physical fitness test composite scores among primary school students, so as to provide empirical evidence for school based weight management and physical health promotion. Methods: A total of 2 112 students from a primary school in Beijing who participated in physical fitness assessments annually from 2008 to 2023 were included and classified into different body weight trajectory groups based on body mass index (BMI) threshold: "normal/overweight-obese". Group based trajectory model was used to identify distinct weight trajectories. Generalized estimating equation and Cox regression were used to analyze the associations between weight trajectories and changes in physical fitness test scores, as well as event risks. Robustness checks were conducted. Results: The prevalence of overweight and obesity among primary school students was 26.50%. BMI showed a significant negative correlation with physical fitness composite scores ( r=-0.19, P <0.01). Four types of weight trajectories were identified: persistent normal group (64.5%, 1 362), persistent overweight- obese group (18.2%, 385), normal to overweight-obese group (14.0%, 296), and overweight-obese to normal group (3.3%, 69). Compared to the persistent normal group, both the normal to overweight-obese and persistent overweight-obese groups showed significantly higher risks of failing the physical fitness test ( HR =4.23, 4.60), and the speed of achieving excellent was slower ( HR = 0.52, 0.40) (all P <0.05). Robustness tests confirmed the stability of the findings. Conclusions Body weight trajectories have a long term impact on physical fitness performance among primary school students. Students with persistent or progressive overweight-obese trajectories have limited score improvement and a higher risk of failure; primary school students with persistent or progressive overweight and obesity should be a key focus.

Tropical diseases, the transmission of which is affected by multiple natural and social factors, pose a great challenge to global public health, notably in African countries. During the past several decades, China and African countries have continuously collaborated for the control of neglected tropical diseases and malaria, which has become an important part of global South-to-South cooperation and global health governance. This article reviews the history of China-Africa cooperation for tropical diseases control, summarizes the experiences and achievements over the past decade, analyzes the current challenges in the coopera tion, and proposes future recommendations. The China-Africa cooperation has achieved significant progress in the control of tropical diseases, such as malaria, schistosomiasis, and filariasis, and established a China-Africa cooperation network for tropical diseases control. Through the "Three-Step" strategy of China-Africa cooperation, the effectiveness of China's integrated control strategies has been validated in Africa, and the application of China's tropical disease control technologies has been promoted in African disease-epidemic countries. Currently, China-Africa collaboration, however, still experiences multiple realistic challenges, such as insufficient resources, difficulty in technology transfer, and weak primary healthcare systems. In the future, both sides are recommended to further strengthen policy coordination, deepen technological cooperation, innovate cooperation models, aiming to continuously promote the high-quality development of China-Africa cooperation for tropical diseases control.

Objective To evaluate the effectiveness of schistosomiasis surveillance in Jiangsu Province during the stage moving from transmission control to transmission interruption, and to analyze the current risk and challenges, so as to provide the evidence for achieving the target of schistosomiasis elimination. Methods Schistosomiasis surveillance data were collected from Jiangsu Province from 2012 to 2024, and the endemic areas, Schistosoma japonicum infections in humans and livestock, Oncomelania hupensis snail distribution and implementation of integrated interventions were descriptively analyzed. In addition, the trends in areas with snails, seroprevalence of human S. japonicum infections and numbers of advanced schistosomiasis cases were assessed using a Joinpoint regression model. Results The endemic areas of schistosomiasis continued to shrink in Jiangsu Province from 2012 to 2024, with the number of schistosomiasis-eliminated counties (cities, districts) increasing from 53 (75.71%) to 63 (96.92%), and interruption of schistosomiasis transmission was achieved across the province. A total of 4 600 300 person-times were tested for serum antibodies against S. japonicum, with 28 719 person-times positive detected; and 616 500 person-times were tested S. japonicum infections among local residents in Jiangsu Province from 2012 to 2024, with only 3 egg-positives detected, and no egg-positives found since 2017. A total of 187 600 herd-times were tested for schistosomiasis in livestock, and no S. japonicum infections were found. O. hupensis snail survey was performed covering 1 018 408.97 hm², and a total of 35 556.35 hm² was found with snail-infested habitats, including 174.40 hm2 of emerging snail-infested habitats. A total of 1 102 800 O. hupensis snails were identified for S. japonicum infections, and no infections were found. The areas of snail-infested habitats appeared a tendency towards a rise in Jiangsu Province from 2019 to 2023 (APC = 23.67%, P < 0.05), and the actual areas of snail-infested habitats appeared a tendency towards a decline from 2012 to 2015 (APC = −22.77%, P < 0.05), and towards a rise from 2015 to 2023 (APC = 9.76%, P < 0.01). The seroprevalence of anti-S. japonicum antibodies appeared a tendency towards a decline among residents in Jiangsu Province from 2017 to 2023 (APC = −14.92%, P < 0.01). In addition, the number of newly diagnosed advanced schistosomiasis cases appeared a tendency towards a decline from 2012 to 2024 (APC = −12.02%, P < 0.01), and the numbers of advanced schistosomiasis patients requiring treatment showed a tendency towards a decline from 2012 to 2021 (APC = −10.56%, P < 0.01) and from 2021 to 2023 (APC = −20.06%, P < 0.01). Conclusions Great progresses had been achieved in schistosomiasis control in Jiangsu Province following transmission control, and transmission interruption had been achieved; however, there are still snail-infested habitats. High-intensity surveillance and integrated control are required to be maintained to advance the achievement of the target of schistosomiasis elimination in Jiangsu Province.

Objective To analyze the status of willingness to participate in health science popularization (HSP) and its influencing factors among medical workers in Guangdong Province. Methods A total of 462 medical workers in Guangdong Province were recruited as the study subjects using a stratified convenience sampling method. The Questionnaire on Influencing Factors of Willingness to Participate in Health Science Popularization, developed by the research team, was used to investigate their willingness to participate in HSP and related variables, including previous communication experience, attitude, moral belief, descriptive norm, injunctive norm, self-efficacy, and social support. Hierarchical regression analysis was used to identify the influencing factors of willingness to participate in HSP. Results The median and 25^th and 75^th percentiles score of willingness to participate in HSP was 4.0 (3.8, 4.5), indicating a moderately high level of willingness. The HSP participation willingness score was positively correlated with scores for previous communication experience, attitude, moral belief, descriptive norm, injunctive norm, self-efficacy, and social support (Spearman correlation coefficients were 0.513, 0.384, 0.507, 0.533, 0.463, 0.556, and 0.435, respectively; all P<0.01). Hierarchical regression analysis showed that previous communication experience, moral belief, descriptive norm and self-efficacy positively predicted willingness to participate in HSP (all P<0.05). Medical workers in the non-Pearl River Delta region had lower willingness than those in the Pearl River Delta region for HSP participation (P<0.05). Conclusion There is still room for improving willingness for HSP participation among healthcare professionals in Guangdong Province. It is recommended to enhance self-efficacy through communication skills training, strengthen professional ethics education, foster a positive peer engagement atmosphere, and intensify resource support and capacity building for HSP in the non-Pearl River Delta region, to improve HSP participation willingness among medical workers in Guangdong Province.

Objective:To explore the short- and medium-term clinical outcomes of covered stent implantation in the treatment of transplant renal artery stenosis (TRAS).Methods:A retrospective analysis was conducted on the clinical data of 12 consecutive patients with TRAS (transplant renal artery stenosis) who underwent covered stent implantation in Henan Provincial People′s Hospital from January 2021 to December 2024. The changes in indicators such as serum creatinine (Cr), blood urea nitrogen (BUN), mean arterial pressure (MAP), peak systolic velocity (PSV), intrarenal resistance index (RI), and the diameter of the stenotic site were analyzed before the operation, one week after the operation, six months after the operation, and 12 months after the operation. Repeated measures analysis of variance was used to investigate the changes of each observation index over time.Results:The surgery was successfully performed on all 12 patients, with a technical success rate of 100%. Among them, 8 cases used self-expanding covered stents, and 4 cases used balloon-expandable covered stents. One week, six months and twelve months after the surgery, the levels of Cr, BUN, PSV and MAP were all lower than those before the surgery. The RI and the diameter of the stenotic site were significantly increased compared with those before the surgery, the difference was statistically significant ( P<0.05). During the perioperative period and the postoperative follow-up period, no surgery-related complications were found. Conclusion:The implantation of the covered stent can effectively relieve the stenosis of the transplant renal artery, significantly improve renal function, and reduce blood pressure levels in TRAS patients, while maintaining excellent short-to medium-term clinical outcomes.

With the acceleration of societal aging, heart failure in the elderly—characterized by a complex metabolic imbalance—has emerged as a pivotal challenge in public health.This condition severely compromises the physical well-being and quality of life among senior populations, primarily due to a pronounced imbalance between cardiac energy supply and demand.Among the various interventions studied, photosynthesis in plants, the principal energy source for aerobic organisms, presents a novel avenue for exploration.By effectively converting solar energy into chemical energy, photosynthesis sustains plant life.Introducing its principles into heart failure treatment could potentially optimize metabolism for elderly patients while significantly reducing oxidative stress and inflammation.Further investigations suggest that the antioxidants and bioactive byproducts generated during photosynthesis may play critical roles in heart failure treatments, particularly in modulating inflammatory pathways.In summary, emulating the mechanisms of photosynthesis could represent a promising strategy for treating heart failure in the elderly.This review aims to delve deeply into the application of photosynthesis in heart failure treatments for older adults and its underlying mechanisms, with the hope of providing insights and guidance for future endeavors in geriatric medicine.
