Objective: To investigate the availability and use of child safety seats among children aged 0-3 years, so as to provide the basis for improving riding safety for children. Methods: Parents of children aged 0-3 years in Huangpu District, Shanghai Municipality, were recruited using the stratified multistage random sampling method from May to July 2024. Demographic information, family travel patterns, the use of child safety seat and related health beliefs were collected using questionnaire surveys. Factors affecting the use of child safety seats were identified using a multivariable logistic regression model. Results: Totally 514 valid questionnaires were recovered, with an effective rate of 96.98%. The respondents included 122 fathers (23.74%) and 392 mothers (76.26%), with a median age of 34.00 (interquartile range, 5.00) years. There were 446 families equipping with child safety seats, accounting for 86.77%; and 169 families using child safety seats, accounting for 32.88%. Multivariable logistic regression analysis showed that the parents who had children aged >1-2 years (OR=0.597, 95%CI: 0.366-0.973), travelled 2-4 times per month (OR=0.359, 95%CI: 0.213-0.607) or once per month or less (OR=0.384, 95%CI: 0.202-0.729), and scored high in perceived barrier (OR=0.634, 95%CI: 0.486-0.827) were less likely to use child safety seats; the parents who had children with local household registration (OR=2.506, 95%CI: 1.356-4.633), travelled 5-<10 km (OR=1.887, 95%CI: 1.148-3.101) or ≥10 km (OR=2.319, 95%CI: 1.355-3.967), always wore seat belts (OR=2.342, 95%CI: 1.212-4.524), scored high in perceived susceptibility (OR=1.392, 95%CI: 1.091-1.778) and self-efficacy (OR=1.413, 95%CI: 1.156-1.727) were more likely to use child safety seats. Conclusions Equipping family cars with child safety seats and using them can prevent and reduce traffic injuries among children aged 0-3 years. It is recommended to strengthen publicity to promote the use of child safety seats.

Objective: To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures. Methods: Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC). Results: A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively. Conclusions The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.

Objective To investigate the levels of gross α and gross β activities in different water types within a 40-kilometer radius around the Zhangzhou Nuclear Power Plant prior to its operation. Methods In 2018, drinking water samples were collected from the area surrounding the nuclear power plant during both the wet and dry seasons, including source water, treated water, tap water, and well water. The gross α and gross β activity concentrations were measured using a low-background α/β counter, followed by statistical analysis. Results A total of 80 water samples from different sources around the Zhangzhou Nuclear Power Plant were collected. The average gross α and gross β activity concentrations during the wet season were (0.110 ± 0.036) Bq/L and (0.643 ± 0.028) Bq/L, respectively, while those during the dry season were (0.124 ± 0.032) Bq/L and (0.624 ± 0.026) Bq/L, respectively. There were no significant differences in the gross α and gross β activity concentrations between the wet and dry seasons for the overall sample set (P > 0.05). However, there were statistically significant differences in the gross α and gross β activity concentrations between the wet and dry seasons for source water and well water (Z_wet = −2.005, −2.123; Z_dry = −1.943, −3.090; P < 0.05). Conclusion The radioactivity levels in different water types within various ranges around the Zhangzhou Nuclear Power Plant before its operation were determined. The measured activity concentrations were at the same level as those from previous investigations in other regions of Fujian Province.

BACKGROUND: Changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels may not fully translate into patient-reported health status in patients with heart failure (HF). We aimed to evaluate the correlation between NT-proBNP levels and patient-reported health status changes at one month after discharge of patients, and their associations with risk of death and rehospitalization in patients with acute HF. METHODS: We used data from the China Patient-centered Evaluative Assessment of Cardiac Events Prospective Heart Failure Study (PEACE 5p-HF Study). Patient-reported health status was measured by the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Patients who were hospitalized for HF and completed the KCCQ-12 and NT-proBNP tests before and one month after discharge were eligible in our study. We stratified patients into different groups based on NT-proBNP levels (i.e., improved, stable, and deteriorated) and KCCQ-12 scores (i.e., not deteriorated and deteriorated). We also examined the associations of the joint NT-proBNP and KCCQ-12 change with the risk of one-year and four-year clinical outcomes. RESULTS: A total of 2461 patients were included in the analysis. The mean age was 64.06 ± 13.51 years, and 36.37% (895/2461) of the study population were female. Among patients with improved NT-proBNP levels, 115 (10.95%) patients had deteriorated KCCQ-12 scores. The correlation between the change in the KCCQ-12 score and NT-proBNP level was weak ( r2 = 0.002, P = 0.013). Stratification by changes in the KCCQ-12 score revealed subgroups with distinctive risks, such that patients with deteriorated KCCQ-12 scores in any of the NT-proBNP change groups exhibited an increased risk of one-year all-cause death than participants with not deteriorated KCCQ-12 scores in any of the NT-proBNP change groups. Patients with improved NT-proBNP levels and deteriorated KCCQ-12 scores presented greater risks of one-year all-cause death (hazard ratio [HR]: 2.45, 95% confidence interval [CI]: 1.34-4.48) than patients with stable NT-proBNP levels and not deteriorated KCCQ-12 scores (HR [95% CI], 1.77 [1.25-2.53]). CONCLUSIONS: A discrepancy between changes in NT-proBNP levels and KCCQ-12 scores was common. The change in NT-proBNP levels was not sufficient to characterize critical aspects related to HF during one month after discharge of patients. Changes in the KCCQ-12 score exhibit complementary information to NT-proBNP levels for the prediction of clinical outcomes in patients with acute HF.

Objective:To observe the clinical and imaging features of patients with retinal vein occlusion (RVO) complicated with retinal artery occlusion (RAO).Methods:A retrospective clinical study. Fifteen patients with 15 eyes with RVO combined with RAO and macular edema diagnosed by ophthalmology examination in the Department of Ophthalmology, First People's Hospital of Xianyang City during 2 years from February 1, 2022 to January 31, 2024 were included in the study. Branch retinal vein occlusion (BRVO) combined with branch retinal artery occlusion (BRAO) occurred in 3 cases and 3 eyes. Central retinal vein occlusion (CRVO) complicated with central retinal artery occlusion (CRAO) in 12 eyes. Best corrected visual acuity (BCVA), intraocular pressure, scanning laser ophthalmoscope, optical coherence tomography (OCT), fluorescein fundus angiography (FFA) and serum homocysteine were all performed. OCT angiography (OCTA) was performed in 6 eyes. All eyes were treated with intravitreal injection of anti-vascular endothelial growth factor drugs. After the initial 1 treatment, dosage was assessed as needed. Follow-up was performed every month for 12 months after treatment. FFA inspection was performed at 3 months. During follow-up, it was found that there were no perfusion areas of capillaries, and retinal laser photocoagulation therapy was given in time. Fundus manifestations, FFA, OCT, OCTA characteristics and causes of disease were analyzed retrospectively.Results:There were 15 eyes in 15 cases, 9 eyes in 9 males; 6 women with 6 eyes. Age was (61.0±9.7) years. All complained of painless vision loss in one eye. All eyes were positive for relative afferent pupillary disorder. Contralateral congenital optic disc defect was in 1 case; hypertension was in 6 cases; hyperhomocysteinemia was in 2 cases; cerebral infarction was in 3 cases; coronary heart disease was in 1 case. CRVO combined with CRAO was in 12 eyes BCVA light sensitivity-0.25. The BCVA of BRVO combined with BRAO were 0.1, 0.4 and 0.25, respectively. All the patients had retinal edema in the posterior pole of the eye, venous sinuous, dilated, thin arteries and stiff shape. The retina presents with flaky or flame-like bleeding. Posterior polar retinal lint patch was in 13 eyes. In 12 eyes with CRVO combined with CRAO, optic disc edema was observed and the boundary was not clear. In 3 eyes with BRVO combined with BRAO, no obvious abnormality was found in the optic disc, and the boundary was clear. FFA examination showed no or prolonged arterial filling, delayed retinal vein laminar flow, relatively slow or even no capillary filling, macular arteriole atretosis to varying degrees, arch ring structure destruction, optic disc telangiectasia and fluorescein leakage. OCT examination showed that the middle and inner layers of the retina were thickened to varying degrees, the diffuse reflex was enhanced, the interlayer structure was unclear, and the reflex of the lower retinal tissue was weakened. The blood flow density of superficial capillary plexus and deep capillary plexus (DCP) decreased in 6 eyes undergoing OCTA examination. Decreased or interrupted blood flow in the vascular bed of DCP. During the follow-up period, there were 13 eyes with no perfusion area of retinal capillary. The time of occurrence was (1.14±0.95) (0-2) months, and the area was 10-75 disc area. Optic nerve atrophy occurred in 5 eyes. At the last follow-up, visual acuity increased, unchanged and decreased in 12, 2 and 1 eyes, respectively.Conclusions:The pathogenesis of RVO-RAO is complicated. Most RVO and RAO occurred simultaneously, and a few RVO occurred several days after RAO. Although the RAO manifestations are not typical, the radiographic features are both RVO and RAO. Compared with BVRO combined with BRAO, the prognosis of visual acuity in CRAO patients with CRVO is worse.

Objective:To analyze the existing problems in maternal and child health services in Shanghai′s communities, so as to provide references for the continuous improvement and enhancement of maternal and child health work in community.Methods:Retrieve relevant literature on community maternal and child health services in Shanghai from databases such as CNKI, Wanfang, VIP, Chinese biomedical literature database and PubMed for text analysis, with a search period from 2009 to 2023. From August 2022 to May 2023, a purposive sampling method was used to select community health service centers in Shanghai for participatory observation. Interviews were conducted with maternal and child health service providers in community, management personnel at all levels, and obstetric experts from tertiary hospitals participating in the construction of medical alliances to understand the problems that exist in the process of providing maternal and child health services in community service centers. Based on text analysis, participatory observation, and interview results, a structure-process-outcome theory model was used to sort out a list of problems of maternal and child health services in Shanghai′s community. An electronic questionnaire was created based on the list of questions, and maternal and child health service personnel in each jurisdiction were invited to rate the existing problems from three aspects: importance, severity, and solvability. The key issues was determined based on the total score of each problem.Results:A list of 24 issues related to maternal and child health services in Shanghai′s community has been formed, with the structural dimension including team building and hardware facilities, the process dimension including mechanism construction, implementation process, and institutional coordination, and the result dimension only including system result category. According to the survey results, the three key questions with a total score greater than 7 were identified as the need for improvement in the maternal and child health knowledge and skills of service personnel; Insufficient staffing of service personnel, lack of dedicated personnel and specialized talents; The health information platform was not well-established, and institutions could not fully and timely share diagnosis and treatment data.Conclusions:This study has identified a problem list for maternal and child health care services in Shanghai′s communities, as well as key issues that urgently need to be addressed, which can provide reference for improving the quality of maternal and child health care services in Shanghai′s communities.
