AIM: To investigate the current status of retinopathy of prematurity(ROP)in premature infants in Xiamen and analyze its influencing factors, aiming to provide a scientific basis for clinical treatment and preventive strategies.METHODS: A retrospective study was conducted on the case data of 363 preterm infants with a gestational age of <32 wk who underwent fundus examination at Xiang'an Hospital of Xiamen University from February 11, 2020 to February 25, 2023. The incidence of ROP was statistically analyzed based on the screening results. All premature infants were divided into ROP group(37 cases, 64 eyes)and non-ROP group(326 cases, 652 eyes). General clinical data and perinatal-related information of the two groups were compared, and multivariate Logistic regression analysis was used to identify factors influencing the occurrence of ROP in premature infants.RESULTS: A total of 363 premature infants were included in this study. The fundus screening results showed that a total of 37 cases(64 eyes)of premature infants were detected with ROP, including 10 cases(10 eyes)monocular and 27 cases(54 eyes)binocular, with an overall incidence of 10.2%(37/363). The severity was determined according to the ROP international classification standard(ROP is divided into 5 stages, with stage I being the least severe and stage V the most severe). Among the 64 eyes, 30 eyes(46.9%)were in stage I, 20 eyes(31.3%)were in stage II, 10 eyes(15.6%)were in stage III, 4 eyes(6.3%)were in stage IV, and there were no cases in stage V. By comparing the clinical data of the two groups, no significant differences were found in gender, mode of delivery, singleton or multiple births, premature rupture of membranes, history of asphyxia, patent ductus arteriosus(PDA), or neonatal respiratory distress syndrome(NRDS)between the two groups(all P>0.05). However, premature infants in the ROP group had significantly younger gestational age and lower birth weight compared to those in the non-ROP group(all P<0.05). Additionally, the ROP group had higher proportions of longer hospital stays, bronchopulmonary dysplasia(BPD), neonatal sepsis, anemia, oxygen therapy for more than 1 wk, oxygen concentration above 40%, and blood transfusion treatment(all P<0.05). Multivariate Logistic regression analysis revealed that combined neonatal sepsis(OR=166.985, 95% CI: 35.239-791.277, P<0.001), anemia(OR=8.111, 95% CI: 2.064-31.871, P=0.003), oxygen use time >1 wk(OR=10.216, 95% CI: 2.543-41.039, P=0.001), oxygen therapy concentration >40%(OR=7.647, 95% CI: 1.913-30.566, P=0.004), and receiving blood transfusion therapy(OR=5.879, 95% CI: 1.412-24.470, P=0.015)were the main risk factors affecting the occurrence of ROP in preterm infants, and the higher birth weight of preterm infants was a protective factor for ROP(OR=0.093, 95% CI: 0.022-0.394, P=0.001).CONCLUSION: The incidence of ROP in premature infants is relatively high, and there are multiple influencing factors. Low birth weight, neonatal sepsis, anemia, oxygen therapy, and blood transfusion treatment are high-risk factors for ROP in premature infants. Clinical attention should be given to such infants, and fundus screening should be conducted in a standardized manner to provide early treatment, thereby further reducing the risk of ROP in premature infants.

Objective: To evaluate the prevalence and future trend of change of the disease burden of injuries in Chinese children and adolescents from 1990 to 2021, so as to provide reference for injury prevention and control in this population. Methods: Using data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 (GBD 2021), the trend of change in the disease burden of injuries in children and adolescents in China from 1990 to 2021 was analyzed by the Joinpoint regression model. The Bayesian age period cohort model (BAPC) was used to predict the disease burden of injuries among children and adolescents in China from 2022 to 2031. Results: From 1990 to 2021, the standardized incidence rate, standardized prevalence rate, standardized mortality rate, and standardized disability adjusted life years (DALYs) rate of injuries among children and adolescents in China showed an overall downward trend (AAPC=-1.14%, -0.76%, -5.41%, -5.03%, P <0.05). For different genders, the standardized incidence rate (7 106.00/100 000, 5 388.00/100 000), standardized mortality rate (92.00/100 000, 19.00/ 100 000 ), and standardized DALYs rate (7 834.00/100 000, 1 673.00/100 000) of injuries in boys were higher than the rate of injuries in girls in 1990 and 2021 (5 188.00/100 000, 3 874.00/100 000; 61.00/100 000, 10.00/100 000; 5 398.00/100 000, 945.00/100 000). Compared with Asia and globally, China had the fastest decline in the standardized mortality rate (AAPC= -5.41 ) and the slowest decline in the standardized prevalence rate (AAPC=-0.76) among children and adolescents. The results of the Joinpoint burden trend analysis demonstrated that the standardized incidence rate of injuries showed an increasing trend from 2005 to 2021, and the standardized prevalence rate of injuries showed an increasing trend from 2006 to 2021. Among the different age groups, the disease burden of injuries was highest in the 15-19-year-old group in 2021. For different types of injuries, the standardized incidence rate, standardized mortality rate, and standardized DALYs rate of unintentional injury were higher than those of transport injury, and self harm and interpersonal violence from 1990 to 2021. The BAPC prediction model showed that the standardized incidence rate ( 4 833.05/ 100 000-5 313.70/100 000) and standardized prevalence rate (5 433.90/100 000-5 821.88/100 000) of injury showed an increasing trend, and the standardized mortality rate (13.69/100 000-5.52/100 000) and the standardized DALYs rate ( 1 226.37/ 100 000-510.14/100 000) showed a decreasing trend during 2022-2031. The analysis of influencing factors found that children and adolescents who drank alcohol were at high risk of injury burden. Conclusions From 1990 to 2021, the injury burden of children and adolescents in China generally showed a downward trend. The standardized incidence rate and standardized prevalence rate of injuries are predicted to increase from 2022 to 2031. More targeted and individualized intervention measures should be developed to reduce the injury burden in children and adolescents.

Objective: The aging demographic landscape worldwide portends a heightened prevalence of neurodegenerative disorders. Foremost among these is Alzheimer’s disease (AD), the foremost cause of dementia in older adults. The shortage of efficacious therapies and early diagnostic indicators underscores the imperative to identify non-invasive biomarkers for early detection and disease monitoring. Recently, blood metabolites have emerged as promising candidates for AD biomarkers. Methods: Leveraging nuclear magnetic resonance (NMR) spectroscopy on plasma specimens, we conducted a cross-sectional study encompassing 35 AD patients and 35 age-matched healthy controls. Cognitive function was evaluated using the mini-mental state examination in all participants, followed by peripheral blood sample collection. We utilized univariate and multivariate analyses to perform targeted lipidomic profiling via NMR spectroscopy. Results: Our study revealed significant differences in the expression profiles of low-density lipoprotein-associated subfractions in females and high-density lipoprotein-associated subfractions in males between AD patients and healthy controls (all p<0.05). However, there was no significant metabolite overlap between males and females. Furthermore, receiver operating characteristic curve analysis demonstrated that the combination of lipid metabolites had good diagnostic values (all area under the curve>0.70; p<0.05). Conclusion Our findings suggest that the blood plasma samples using NMR hold promise in distinguishing between AD patients and healthy controls, with significant clinical implications for advancing AD diagnostic methodologies.

Objective:To explore the role and the intervention effect of emodin in intestinal neuropathy in rats with severe acute pancreatitis (SAP) through the nucleotide binding oligomerization domain like receptor protein 3/cysteine containing aspartic acid protease-1 (NLRP3/Caspase-1) pathway.Methods:Forty male healthy SD rats aged 6-8 weeks with a weight of approximately 200g were randomly divided into control group, SAP model group, emodin treatment (EMO) group, and NLRP3 knockdown group. SAP were induced by retrograde injection of sodium deoxycholate into the pancreatic duct of rats and serum amylase of which were detected. The effective NLRP3 knockdown sequence was screened for NLRP3 knockdown animal experiments. Fluorescence quantitative polymerase chain reaction was used to detect the expression of NLRP3, Caspase-1, gasdermin-D (GSDMD), interleukin (IL)-1β, IL-18 and tumor necrosis factor-α(TNF-α) in the small intestine of each group. Immunofluorescence staining was used to detect the expression of glial fibrillary acidic protein (GFAP) in the small intestine of each group.Results:The amylase levels of the control group, SAP group, EMO group, and NLRP3 knockdown group were (277.73±24.92) U/L, (1018.57±282.89) U/L, (625.43±134.40) U/L, and (391.01±27.63) U/L, respectively. The SAP and EMO groups were significantly higher than the control group ( P<0.001), while the EMO and NLRP3 knockdown groups were significantly lower than the SAP group (all P<0.001). Compared with control group, the expression levels of NLRP3, Caspase-1, IL-1β, IL-18, TNF-α and GSDMD in SAP group were increased, with statistical significance (all P<0.001). Compared with SAP group, the NLRP3 knockdown group showed the expressionlevels of the above 6 genes were all decreased, and EMO group showed decreased gene expressing levels of NLRP3, IL-1β, IL-18 and TNF-α, with statistical significance (all P<0.05). The relative expression of GFAP in small intestine of control group, SAP group, EMO group and NLRP3 knockdown group were (1.00±0), (1.66±0.11), (1.13±0.02) and (1.13±0.02), respectively. Among them, the expression of GFAP in SAP group was increased compared with the control group; The expression of GFAP in EMO group and NLRP3 knockdown group was lower than that in model group, and the differences were statistically significant (all P<0.05). Conclusions:Emodin and knocking down NLRP3 can both promote the repair of SAP small intestine injury through the NLRP3/Caspase-1 signaling pathway, and thus play a protective role in the intestine.

Objective:To systematically review the medical decision-making for children with autism spectrum disorder (ASD) from the perspective of caregivers.Methods:It was a systematic review. Using search terms as “Autism”“loneliness disorder”“autism spectrum disorder”“parents”“caregiver”“medical decision making”, etc., qualitative studies on medical decision-making of ASD caregivers in the databases of PubMed, Web of Science, Cochrane Library, Embase, Scopus, CNKI.com, Wanfang Database, VIP database, and Chinese Biomedical Literature database were searched. The search was conducted from the inception of the databases to July 31, 2022, and the data was organized from August 1 to September 1, 2022. The literature quality was evaluated by two researchers according to the quality evaluation criteria for qualitative research at the Centre for Evidence-based Health Care, Joanna Briggs Institute, Australia. Pooled integration method was used to integrate the study results and evaluate the medical decision-making of children with ASD from the perspective of caregivers.Results:Seventeen studies were included, with two studies rated as quality grade A and fifteen studies rated as quality grade B. A total of 36 research findings were extracted. These findings were grouped into ten new categories based on similarities, which were further synthesized into three overarching results: the symptom-driven medical decision-making process, delays in medical decision-making due to individual, family, and societal factors, and the influence of personal experiences and multiple external pressures on medical decision-making.Conclusion:The factors that lead to the delay or promotion of medical decision of caregivers of children with ASD are complicated, and comprehensive intervention measures should be taken at individual, family and social levels to promote early medical diagnosis and intervention of the children with ASD.

Objective:Adverse cardiovascular events are the leading cause of death in peritoneal dialysis patients.Identifying indicators that can predict adverse cardiovascular events in these patients is crucial for prognosis.This study aims to assess the value of dual-specificity phosphatase 6(DUSP6)in peripheral blood mononuclear cells as a predictor of adverse cardiovascular events after peritoneal dialysis in diabetic nephropathy patients. Methods:A total of 124 diabetic nephropathy patients underwent peritoneal dialysis treatment at the Department of Nephrology of the First Affiliated Hospital of Hebei North University from June to September 2022 were selected as study subjects.The levels of DUSP6 in peripheral blood mononuclear cells were determined using Western blotting.Patients were categorized into high-level and low-level DUSP6 groups based on the median DUSP6 level.Differences in body mass index,serum albumin,high-sensitivity C-reactive protein,and dialysis duration were compared between the 2 groups.Pearson,Spearman,and multiple linear regression analyses were performed to examine factors related to DUSP6.Patients were followed up to monitor the occurrence of adverse cardiovascular events,and risk factors for adverse cardiovascular events after peritoneal dialysis were analyzed using Kaplan-Meier and Cox regression. Results:By the end of the follow-up,33(26.61%)patients had experienced at least one adverse cardiovascular event.The high-level DUSP6 group had higher body mass index,longer dialysis duration,and higher high-sensitivity C-reactive protein,but lower serum albumin levels compared to the low-level DUSP6 group(all P<0.05).DUSP6 was negatively correlated with serum albumin levels(r=-0.271,P=0.002)and positively correlated with dialysis duration(rs=0.406,P<0.001)and high-sensitivity C-reactive protein(rs=0.367,P<0.001).Multiple linear regression analysis revealed that dialysis duration and high-sensitivity C-reactive protein were independently correlated with DUSP6 levels(both P<0.05).The cumulative incidence of adverse cardiovascular events was higher in the high-level DUSP6 group than in the low-level DUSP6 group(46.67%vs 7.81%,P<0.001).Cox regression analysis indicated that low serum albumin levels(HR=0.836,95%CI 0.778 to 0.899),high high-sensitivity C-reactive protein(HR=1.409,95%CI 1.208 to 1.644),and high DUSP6(HR=6.631,95%CI 2.352 to 18.693)were independent risk factors for adverse cardiovascular events in peritoneal dialysis patients. Conclusion:Dialysis duration and high-sensitivity C-reactive protein are independently associated with DUSP6 levels in peripheral blood mononuclear cells of diabetic nephropathy patients undergoing peritoneal dialysis.High DUSP6 levels indicate a higher risk of adverse cardiovascular events.
