ObjectiveTo investigate the screen exposure situation and its determinants among children aged 0‒3 years, so as to offer insights for intervening in children’s screen exposure. MethodsA total of 1 797 children who received routine physical examinations in Shaoxing Maternal and Child Health Care Hospital from January 2024 to December 2024 were enrolled. A self-designed screen exposure questionnaire was used to collect demographic information for children, educational attainment of parents and main caregivers, contents of video screen exposure, and video devices. The screen exposure rate among children was analyzed, and a multivariable logistic regression model was used to analyze its influencing factors. ResultsAmong the 1 797 children aged 0‒3 years, 935 were boys (52.03%), and 862 were girls (47.97%). The mean age was (21.81±9.97) months old. A total of 335 infants and toddlers had an average daily cumulative screen exposure >1 hour over the past week, with a screen exposure rate of 18.64%. Multivariable logistic regression analyses showed that the risk of screen exposure was higher with each one-year increase in the child’s age (OR=1.90, 95%CI: 1.58‒2.28), with cartoons or nursery rhymes as the main video content (OR=2.09, 95%CI: 1.27‒3.44; OR=1.75, 95%CI: 1.02‒2.97, respectively), and with watching videos during the period for meals or for parents doing housework, or before bedtime (OR=3.51, 95%CI: 2.08‒5.92; OR=2.92, 95%CI: 1.75‒4.88; OR=2.01, 95%CI: 1.16‒3.49, respectively). In contrast, higher maternal educational levels (OR=0.67, 95%CI:0.49‒0.92) were associated with a reduced rate of screen exposure. ConclusionAmong children aged 0‒3 years, their screen exposure is associated with their age, maternal educational level, screen content, and time of video watching. The departments should strengthen the education on screen exposure for older children and the mothers with lower education, while advocating for parents to scientifically and normatively manage screen content and time.

Objective: To analyze the characteristics and key risk factors of abnormal blood disposal throughout the 2024-2025 blood collection and supply process based on nationwide multi-site monitoring data, develop a comprehensive prevention and control strategy across the entire chain, reduce preventable blood waste, and ensure clinical blood safety. Methods: According to the Guidelines for Haemovigilance (T/CSBT 001-2026), we extracted 74 cases of abnormal blood disposal events reported by the China Blood Transfusion Association′s Blood Safety Monitoring System from January 1 2024, to December 31 2025, and conducted descriptive statistical analysis on the distribution of events, types of deviations, root causes, and classifications of disposal manifestations. Results: A total of 664 adverse events related to blood collection and supply were reported over two years, with 74 cases involving discarded abnormal blood units, accounting for 11.1% of the total. Among these, blood component preparation (40.5%) and blood collection (37.8%) remained traditional high-risk stages. The proportion of blood waste occurring during storage, distribution, and transportation increased from 7.7% in 2024 to 34.3% in 2025. Deviations from standard operating procedures (SOP) by personnel were the primary cause, accounting for 74.3% of cases. Discarded blood units were categorized into four types: compromised closed blood bag systems (40 cases), mainly due to inadequate heat sealing, physical damage, or dropped bags; blood out of the cold chain (12 cases), primarily resulting from blood being left at work sites; imbalanced proportion of preservation solution (10 cases), mostly caused by blood collection volumes exceeding the standard capacity of blood bags; and other causes (12 cases). Conclusion: Human operational errors are the core cause of abnormal blood waste. The collection and preparation stages have long been at high-risk, and the risks in the storage and transportation stages have been increasing year by year. We should focus on standardizing personnel management, improving specialized operation norms such as heat sealing, transportation, and storage, establishing a full-process intelligent cold chain monitoring and multi-node visual verification mechanism, and systematically reducing the occurrence rate of abnormal blood waste through a closed-loop quality intervention system, thereby improving the utilization efficiency of voluntary blood donation resources.

ObjectiveTo observe the effect of modified Huanglian Wendantang on oxidative stress in metabolic syndrome. MethodsA total of 180 patients with metabolic syndrome treated in the outpatient clinics and wards of the First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine from October 2023 to May 2025 were enrolled in this study. According to the randomized numerical table method， the patients were assigned into two groups （90 cases）. The basic treatment of the two groups was the same， and the observation group was additionally treated with modified Huanglian Wendantang. The course of treatment was 3 months. The two groups were compared in terms of traditional Chinese medicine （TCM） efficacy， obesity degree ［waist circumference （WC）， body mass index （BMI）， waist-to-hip ratio （WHR）， waist-to-height ratio （WHtR）］， blood pressure indicators ［systolic blood pressure （SBP） and diastolic blood pressure （DBP）］， lipids and glucose indicators ［total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， fasting insulin （FINS）， fasting glucose （FPG）， 2-hour postprandial glucose （2 h PG）， and glycosylated hemoglobin （HbA1c）］， insulin resistance indicators ［homeostatic model assessment for insulin resistance （HOMA-IR）， triglyceride-glucose index （TYG index）， triacylglycerol-to-high-density lipoprotein cholesterol （TG/HDL） ratio］， oxidative stress indicators ［malondialdehyde （MDA）， superoxide dismutase （SOD）， glutathione （GSH）， glutathione peroxidase （GSH-Px）， catalase （CAT）， and reactive oxygen species （ROS）］， and the safety of treatment. ResultsIn terms of TCM efficacy， the treatment in the observation group was significantly effective in 46 cases， effective in 30 cases， and ineffective in 10 cases， with the total effective rate of 88.4%. The treatment in the control group was significantly effective in 33 cases， effective in 28 cases， and ineffective in 23 cases， with the total effective rate of 72.6%. The observation group had higher total effective rate than the control group （χ²=11.26，P<0.05）. After treatment， both groups showed declined levels of WC， BMI， WHR， WHtR， SBP， DBP， TC， TG， LDL-C， FPG， FINS， 2 h PG， HbA1c， HOMA-IR， TG/HDL ratio， TYG index， MDA， and ROS and elevated levels of HDL-C， SOD， GSH， GSH-Px， and CAT （P<0.05）. After treatment， the observation group showed lower levels of WC， BMI， WHR， WHtR， TC， TG， LDL-C， FPG， FINS， 2 h PG， HbA1c， HOMA-IR， TG/HDL ratio， TYG index， MDA， and ROS and higher levels of HDL-C， SOD， GSH， GSH-Px， and CAT than the control group （P<0.05）. However， after treatment， there was no significant difference in SBP or DBP between the observation group and the control group. No significant adverse reactions were observed in either group. ConclusionModified Huanglian Wendantang can significantly alleviate metabolic syndrome symptoms and reduce oxidative stress， exhibiting antioxidant effects. Moreover， it does not induce adverse reactions， demonstrating safety.

Objective To investigate the potential role of plasma adiponectin concentration in predicting the response of patients with depression to electroconvulsive therapy(ECT).Methods This study enrolled depressive patients scheduled for ECT at the First Hospital of Shanxi Medical University between January 2022 and March 2024.Patients were categorized as either ECT responders(>50%reduction)or non-responders(≤50%reduction)based on post-ECT reduction rate of the 24-item Hamilton depression scale(HAMD)scores from baseline.Plasma adiponectin levels were measured in all patients before their first ECT treatment.To identify predictors of ECT response in patients with depression,the predictive value of plasma adiponectin was evaluated using receiver operating characteristic(ROC)curve analysis.Results A total of 80 patients with depression were enrolled including 44 in the ECT-responsive group and 36 in the non-responsive group.The plasma adiponectin level was significantly higher in the responsive group than in the non-responsive group[5.67(3.64,10.55)μg/mL vs.4.01(2.59,5.04)μg/mL,P=0.002].Pearson correlation analysis revealed a significant positive correlation between plasma adiponectin levels and the HAMD reduction rate(r=0.300,P=0.007).Multivariate logistic regression analysis showed that plasma adiponectin was independently associated with the response to ECT in patients with depression(OR=1.218,95%CI:1.009-1.470,P=0.040).Furthermore,ROC curve analysis demonstrated that the area under the curve(AUC)for adiponectin in predicting ECT response was 0.748(95%CI:0.583-0.813).Conclusion Pretreatment plasma adiponectin may serve as a potential biomarker for predicting response to ECT in patients with depression.

Ganoderic acid is a class of lanostane-type triterpenoids found in Ganoderma species, and is one of the most important pharmacologically active components in G. lucidum, exhibiting antioxidant, anti-neuropsychiatric, anti-tumor, and immune-enhancing properties. The content of ganoderic acid in G. lucidum is very low, and the traditional extraction process is complex, yielding minimal amounts at high cost. The biosynthetic pathway of G. lucidum triterpenoids(GLTs), including the synthesis of different structural forms of ganoderic acid from lanosterol, as well as the molecular regulatory mechanisms involving key regulatory enzyme genes and their functions, are not yet fully understood. With the continuous development of synthetic biology technologies, there has been a deeper understanding of the biosynthesis and metabolic regulation pathways of ganoderic acid and its derivatives at the molecular level. Research has explored the key regulatory enzyme genes related to ganoderic acid biosynthesis and their functions. Moreover, through the optimization of synthetic biology and culture conditions, large-scale production and preparation of GLTs at the cellular level have been achieved. This paper reviews and analyzes the latest research progress on the biosynthesis pathways and metabolic regulation of GLTs, focusing on the configuration of ganoderic acid and its derivatives, the biosynthetic pathways, key enzyme genes, transcription factors related to ganoderic acid biosynthesis, signal transduction mechanisms, and factors affecting triterpenoid biotransformation. This review is expected to provide a theoretical basis and technical reference for improving the efficient production of triterpenoid pharmacological components and the exploitation and utilization of G. lucidum resources.
