Objective: Blood safety surveillance is a critical measure for the objective assessment of blood quality and enhancing transfusion safety. This study aims to comprehensively understand the current status of blood safety surveillance and management in blood collection and supply institutions in Sichuan Province, systematically analyze existing problems and vulnerabilities, and provide a basis for optimizing management strategies and improving capabilities to ensure blood safety. Methods: The Blood Safety Surveillance questionnaire was designed, covering adverse donor reaction reporting, management of adverse events, and transfusion adverse reaction feedback. An online survey was conducted via Questionnaire Star platform among 21 blood collection and supply institutions in the province, gathering information on management systems, process implementation, and utilization of monitoring data. The collected data were organized and statistically analyzed using Excel. Results: The questionnaire response rate and validity rate were both 100%. Blood collection and supply institutions in Sichuan Province have generally established a blood safety surveillance system and achieved positive outcomes. Regarding adverse events in blood collection and supply, 95.24% (20 institutions) have established reporting procedures, and 66.67% (14) collect information through multiple channels such as internal reports, external reports, and statistical trend feedback. A total of 90.48% (19) institutions regularly summarize and analyze adverse event data, and 85.71% (18) produce reports with improvement recommendations based on this analysis.71.43% (15) institutions implement reward and penalty measures, and 71.43% (15) report underreporting or omission due to accountability or performance concerns. In terms of monitoring adverse blood donation reactions, all blood collection and supply institutions have established full-process management systems.76.19% (16) collect data through multiple approaches, including on-site donation records, voluntary donor reports, and donor follow-ups. Adverse reactions were followed up in 95.24% (20) of institutions with 65% (13) completing follow-ups within 24 hours.80.95% (17) have established investigation procedures, while 66.67% (14) believe underreporting or omission still occurs. All blood collection and supply institutions regularly compile statistics on adverse donation reactions. Of these, 85.71% (18) institutions providing feedback to management departments and 90.48% (19) analyzing the data and making recommendations.76.19% (16) institutions use monitoring data for return donor management and targeted care, and 71.43% (15 stations) incorporate it into management reviews. Regarding adverse transfusion reactions, 95.24% (20) institutions have established and implemented procedures for isolating, recalling, and tracing of problematic blood units. However, only 42.86% (9) have established feedback mechanisms of adverse transfusion reaction with hospitals, and only 19.05% (4) support direct reporting via information systems.47.62% (10) institutions regularly analyze adverse transfusion reaction data, and 19.05% (4) provide feedback and recommendations to relevant hospitals. All blood collection and supply institutions reported challenges in collecting hospital feedback, citing complexities in data collection and reporting processes. Conclusion: Blood safety surveillance systems have been preliminarily established in Sichuan Province. However, further strengthening is still required, including conducting in-depth data analysis and utilization, standardizing the configuration of emergency medications and equipment, and improving feedback mechanisms for adverse transfusion reactions. To improve the overall level of blood safety management, it is recommended to strengthen closed-loop data management, improve feedback mechanisms between blood collection and supply institutions and hospitals, foster a non-punitive reporting culture, and systematically advance the regionalization and standardization of the monitoring system. These efforts will contribute to sustainably improving the overall effectiveness and sustainability of blood safety management.

Objective:To analyze the clinical characteristics，laboratory tests，endoscopic features，treatment，and follow-up of peptic ulcers caused by eosinophilic gastrointestinal disorders（EGIDs）in children，with the aim of improving the level of understanding，diagnosis and treatment of EGIDs in children with the onset of peptic ulcers.Methods:A retrospective analysis was conducted on children admitted to the Department of Gastroenterology，Capital Center for Children's Health，Capital Medical University from January 1st，2019 to October 31st，2023，who underwent complete endoscopic examination. The first examination showed the presence of peptic ulcers（gastric or duodenal ulcers）under the endoscope，and were ultimately diagnosed with peptic ulcers caused by EGIDs through examination and follow-up. The clinical characteristics，laboratory tests，endoscopic results，and treatment follow-up were analyzed.Results:Thirty-five children were EGIDs，22 males and 13 females.Twenty-two cases（62.9%）had abdominal pain as the main symptom.Laboratory tests：17 cases（48.6%）showed a decrease in hemoglobin，15 cases（42.9%）showed an increase in eosinophil count，20 cases（57.1%）tested gastro positive for food allergen specific IgE，and 17 cases（48.6%）showed thickening of the intestinal wall on gastrointestinal ultrasound. Endoscopic features：8 cases（22.9%）showed gastric antral ulcers，including 7 cases（20.0%）with multiple gastric antral ulcers，and 25 cases（71.4%）showed duodenal bulb ulcers.There were 15 cases（42.9%）showed huge ulcers，and 14 cases（40.0%）were located in the duodenal bulb. Comparison of clinical characteristics between children with EGIDs（EGIDs group）and those with peptic ulcers caused by Helicobacter pylori infection（Hp group）：the first clinical symptom in both groups was mainly abdominal pain，but the incidence rate in the EGIDs group was lower（62.9% vs 93.5%），and the weigth for length Z score in the EGIDs group was lower［0（-1.6，0.8）vs 1.1（0，1.9）］，with statistical significance（all P<0.05）. Comparison of laboratory tests：the EGIDs group showed a statistically significant difference in hemoglobin levels［120（101，124）g/L vs 130（100，138）g/L］，eosinophil count［0.28（0.13，0.71）× 10 9/L vs 0.16（0.08，0.22）×10 9/L］，a positive rate of food allergen specific IgE detection（57.1% vs 32.3%），and a positive rate of intestinal wall thickening detected by gastrointestinal ultrasound（48.6% vs 16.1%）compared with the Hp group（all P<0.05）. Comparison of endoscopic examinations：multiple ulcers in the gastric antrum were more common in the EGIDs group than in the Hp group（20.0% vs 0），and the difference was statistically significant（ P<0.05）. Conclusion:For children with peptic ulcers with onset of abdominal pain，with anemia or malnutrition，or multiple ulcers in the gastric antrum and huge ulcers in the duodenal bulb detected by endoscopy，it is recommended to perform multi site biopsies to help diagnose EGIDs early.

Objective:To investigate the correlation between body mass index (BMI)/high-density lipoprotein cholesterol (HDL-C) ratio and cerebral small vessel disease (CSVD) in middle-aged and elderly people.Methods:Consecutive middle-aged and elderly patients (aged ≥40 years) who were hospitalized for chronic disease examinations in the Department of Neurology, Jiangning Hospital Affiliated to Nanjing Medical University between February 2022 and May 2024 were included prospectively. According to the overall burden score of CSVD, they were divided into CSVD group (≥1) and non-CSVD group (0). According to age, they divided into middle-aged group (40-59 years old) and elderly group (≥60 years old). The demographic characteristics and clinical data were collected. Binary multivariate logistic regression analysis was used to determine the independent correlation between BMI/HDL-C ratio and CSVD. Forest plot was used to analyze the correlation between BMI/HDL-C ratio and CSVD in different age groups. Results:A total of 710 patients were included, with an age of 66.0±10.0 years and 361 were males (50.8%). There were 261 patients (36.8%) in the CSVD group and 449 (63.2%) in the non-CSVD group. The BMI/HDL-C ratio in the CSVD group was significantly higher than that in the non-CSVD group (23.60±7.00 vs. 20.78±6.40; P<0.001). Multivariate logistic regression analysis showed that BMI/HDL-C ratio was an independent risk factor for CSVD in middle-aged and elderly populations (odds ratio 1.046, 95% confidence interval 1.027-1.064; P<0.001). There were 475 patients in the elderly group, of which 198 (41.7%) had CSVD; there were 235 patients in the middle-aged group, of which 63 (26.8%) had CSVD. Forest plot analysis showed that the association between BMI/HDL-C ratio and CSVD still had statistical significance in different age groups, but the effect intensity was higher in the elderly group than in the middle-aged group. Conclusion:The BMI/HDL-C ratio is independently correlated with CSVD in middle-aged and elderly population, particularly significant in the elderly population.

Objective To investigate the correlation between cognitive impairment of cerebral small vessel disease(CSVD)and white matter hyperintensity grade and cerebral atrophy grade.Methods The data of 213 patients with CSVD were analyzed retro-spectively.The semi-quantitative Fazekas visual score of brain MR was used to evaluate the white matter hyperintensity,and cerebral atrophy was evaluated by the whole cerebral cortex atrophy grade.Mini-mental state examination(MMSE)and Montreal cognitive assessment(Mo CA)were used to evaluate each patient and to classify according to the results.Results There was a statistically sig-nificant difference in age between male and female patients with CSVD(P=0.04,t=4.288).The mean age of males[(66.5±10.3)years]was less than females[(69.5±10.0)years].There was significant difference between patients with different gender and history of hypertension(P=0.02,t=5.424).There were statistical differences between white matter hyperintensity Fazekes grade and MMSE and Mo CA scores(P<0.001,χ2=5.639;P<0.001,χ2=5.843),and there were statistical differences between whole cerebral cortex atrophy grade and MMSE score(P=0.036,χ2=2.895).Conclusion There is a certain correlation between cognitive impairment of CSVD and head MR imaging evaluation grade.

Objective To compare differences in the pharmacological activities of Angelica sinensis and its components on hematopoietic and laxative effects.Methods Kunming mice were randomly divided into eight groups,with 12 mice in each group consisting of equal numbers of males and females.These groups included a normal group,a model group,a positive group,a Angelica sinensis(AS)group,an Angelica sinensis water-soluble(AW)group,an Ethanol extract of Angelicae sinensis(AE)group,and an Angelica sinensis essential oil(AO)group.Except for the normal group,all other groups were established as blood deficiency constipation mouse models through subcutaneous injection of N-acetylphenylhydrazine combined with oral administration of loperamide hydrochloride.On the 7th day of modeling,each group received oral administration of the respective test substance once daily for three consecutive days.General condition and body weight changes of the mice were observed,peripheral blood cells were counted,stool morphology and fecal output were recorded,fecal moisture content and colonic tissue moisture content were determined,small intestine propulsion rate was assessed by a charcoal meal method,and serum levels of β-endorphin(β-EP),cholecystokinin octapeptide(CCK-8),substance P(SP),and vasoactive intestinal peptide(VIP)were determined by ELISA.Differences in the pharmacological activities of Angelica sinensis and its components on hematopoietic and laxative effects were analyzed.Results Compared with the normal group,model group mice showed significantly reduced white blood cell(WBC),red blood cell(RBC),hemoglobin(HGB),hematocrit(HCT),and platelet(PLT)counts,and body weight(P＜0.05 or P＜0.01).Additionally,fecal moisture content,colon moisture content,and small intestine propulsion rate were decreased(P＜0.05 or P＜0.01)and serum CCK-8 and SP levels were also lower(P＜0.01),while serum β-EP and VIP levels increased(P＜0.05).Compared with the model group,AS and AW groups had higher WBC,RBC,HGB,HCT,and PLT counts,defecation volume,fecal moisture content,and colon moisture content(P＜0.05 or P＜0.01).The AE group showed increased WBC,RBC,HGB,HCT,and PLT counts,and colon moisture content(P＜0.05 or P＜0.01),but defecation volume and fecal moisture content were not significantly altered.The AO group exhibited increased fecal moisture content,colon moisture content,and defecation volume(P＜0.05 or P＜0.01),but no significant changes in WBC,RBC,HGB,HCT,and PLT counts.The AE group showed no significant changes in defecation volume,fecal moisture content,and colon moisture content.The AS and AO groups had increased small intestine propulsion rates(P＜0.01),while there was no significant difference in small intestine propulsion rate between the AW and AE groups.The AS group had elevated serum CCK-8 and SP levels(P＜0.01)and decreased serum β-EP and VIP levels(P＜0.01).The AO group had increased serum CCK-8 and SP levels(P＜0.05),but no significant change in serum β-EP and VIP levels.The AW group had decreased serum VIP levels(P＜0.05),but no statistically significant difference in serum CCK-8 and SP levels.Compared with the AS group,the AW group had higher WBC,RBC,HGB,HCT,and PLT counts,while the AO and AE groups had lower levels of these parameters(P＜0.05).Both AW and AO groups had increased fecal moisture content(P＜0.05),and both AW and AE groups had increased colon moisture content(P＜0.05).AO,AE,and AW groups had elevated serum CCK-8 and SP levels and decreased serum β-EP and VIP levels(P＜0.05).In summary,the groups were ordered as follows:AE＞AO＞AS＞AW in terms of blood replenishment,AO＞AS＞AW＞AE in terms of promoting bowel movements,and AO＞AS＞AE＞AW in terms of intestinal motility.Conclusions Angelica sinensis and its components have varying degrees of blood replenishing and bowel-promoting activities.The AE component has strong blood replenishing activity,while the AO component has strong bowel-promoting and defecation-stimulating activity.These findings provide a reference for the development of traditional Chinese medicines based on Angelica sinensis components.

Objective To explore the sleep quality and mental fatigue level in elderly patients with cerebrovascular small disease(CSVD).Methods A total of 222 patients aged over 65 years old hospitalized due to chronic diseases in Department of Neurology of the Affiliated Jiangning Hospi-tal of Nanjing Medical University from August 2022 to June 2024 were recruited prospectively and continuously.According to the CSVD score,they were divided into a CSVD group(CSVD score≥1,148 cases)and a non-CSVD group(CSVD score=0,74 cases).All the patients were evaluated by sleep quality,fatigue and neuropsychological scale when they were fully cooperated and in good condition.Subsequently,the patients in the CSVD group were further assigned into a good sleep subgroup(117 cases)and a poor sleep subgroup(31 patients).Results The CSVD group had significantly higher total score of Pittsburgh sleep quality index(PSQI),sleep quality score,sleep disturbance score,total score of self-rating fatigue,and mental fatigue score than the non-CSVD group(P＜0.01).The sleep quality score,sleep disturbance score,and mental fatigue score were risk factors for CSVD(P＜0.05).The mental fatigue score was significantly higher in the CSVD patients with poor sleep than those with good sleep(4.13±1.15 vs 2.50±1.92,P＜0.01).Conclusion Elderly CSVD patients were more likely to have decreased sleep quality and mental fatigue,and among them,those with poor sleep quality are prone to having mental fatigue than those with good sleep.

Science and technology ethics are important measures to strengthen science and technology governance and promote responsible innovation.China's science and technology ethics construction started relatively late.To adapt to China's science and technology management system and alleviate the contradiction between the constructions of science and technology ethics and the explosive growth of future scientific and technological activities,this paper constructed a"one-top-three-layers"hierarchical and classified science and technology ethics governance framework,as well as analyzed the current situation.It was found that China's science and technology ethics governance system has shortcomings in top-level systems,hierarchical management,ethics governance of emerging technologies,policy implementation in provinces and cities,and the responsibility of innovation subjects.Subsequently,in response to the shortcomings of China's hierarchical and classified science and technology ethics governance system,international advanced experiences were summarized and supplemented by specific cases.Finally,based on actual conditions and international experiences,recommendations for improving China's hierarchical and classified science and technology ethics governance system were proposed from seven aspects,including improving the science and technology ethics provisions in China's legal documents,clarifying the ethical risk levels of various scientific and technological activities in life sciences,medicine,and artificial intelligence,strengthening the ethical governance of emerging technologies,urging provincial government departments to improve their science and technology ethics governance policies,reinforcing the main responsibility of innovation subjects in the hierarchical and classified science and technology ethics governance system,encouraging third-party to take part in science and technology ethics governance work,as well as building a large language model of science and technology ethics governance.

Objective:To explore the clinical and genetic characteristics and follow-up status of pediatric patients with hepatic glycogen storage disease in order to further improve the prognosis.Methods:The clinical data of hospitalized children diagnosed with hepatic glycogen storage disease in the Department of Gastroenterology at the Children's Hospital of Capital Institute of Pediatrics from January 2010 to April 2023 were collected and retrospectively analyzed. The results of laboratory examination and gene sequencing were analyzed, and the number of cases that exceeded three (n) were grouped according to the genetic results: Group 1 was type Ⅰ ( n=8), Group 2 was type Ⅲ ( n=5), and Group 3 was type Ⅸa ( n=8).The growth, development and prognosis of the children were followed up. The related clinical characteristics of pediatric hepatic glycogen storage disease were summarized. Results:Twenty-five pediatric patients with hepatic glycogen storage disease were enrolled in this study, with fifteen males and ten females. The mean age of diagnosis was (29.1±13.5) months. There were twelve cases (48%) accompanied with varying degrees of hypoglycemia, and two cases (8%) with severe hypoglycemia.There were nineteen cases with stature retardation (76%), four cases with anemia (16%), three cases with proteinuria (12%), and one case with cholestasis (4%).The genetic results showed that there were four cases of type Ⅰa (16%), four cases of type Ⅰb (16%), one case of type Ⅱ (4%), five cases of type Ⅲ (20%), two cases of type Ⅳ (8%), one case of type Ⅵ (4%), and eight cases of type Ⅸ (32%).The three subgroups analysis showed that there were significant statistical differences in uric acid and triglycerides among the three groups ( P<0.05), while there were no statistical significant differences in transaminase levels, fasting blood glucose, lactate, cholesterol, and low-density lipoprotein levels ( P>0.05). The height-for-age Z scores of the three groups were -2.86±1.62, -1.46±1.06, and -1.83±0.98, respectively. The growth and development of groups 2 and 3 were significantly improved compared with group 1 ( P<0.05), with Z scores of -2.28±1.07, 0.20±1.54, and 0.10±1.44 after at least one year of follow-up. All pediatric patients with type Ⅸa had discontinued using raw corn starch after more than one year of follow-up and their transaminases had returned to normal. Four pediatric patients with type Ia were orally administered raw corn starch on a regular basis, and the aminotransferases, uric acid, and lactate were normal, with hypoglycemia being monitored. Among the four cases with type Ⅰb, one had recurrent respiratory tract and intestinal infections, two were combined with Crohn's disease, and one was monitored for hypoglycemia. In four cases of type Ⅲ, raw corn starch was discontinued, and a high-protein, low-carbohydrate diet was adopted, with the exception of the presence of high creatine kinase and normal aminotransferase. Liver failure resulted in the death of one type Ⅵ case, while two were type Ⅳ cases; one died, and one case recently had slightly elevated aminotransferase. Conclusion:When pediatric patients exhibit manifestations such as hepatomegaly, elevated transaminases, fasting hypoglycemia, and delayed growth and development, it is necessary to be alert to hepatic glycogen storage disease. Clinical manifestations and biochemical indicators combined with genetic testing are helpful for the diagnosis of hepatic glycogen storage disease. Simultaneously, targeted nutritional management should be carried out according to the metabolic characteristics of different subtypes, with attention on growth and development status.

OBJECTIVE To study the therapeutic effect of Hongqi Shenmai Drink on heart failure(HF)after acute myocardial in-farction(AMI)with qi-yin deficiency and blood stasis,and its regulatory effect on serum secretory phosphoprotein 1(SPP1)in AMI-HF patients.METHODS Seventy-six patients with AMI-HF of qi-yin deficiency and blood stasis type were enrolled in this study from three centers:Affiliated Hospital of Integrated Traditional and Western Medicine,Nanjing University of Chinese Medicine;Hangzhou Xiaoshan Hospital of Traditional Chinese Medicine;and Changzhou Hospital of Traditional Chinese Medicine.They were randomly di-vided into a traditional Chinese medicine(TCM)group and a control group,with 38 patients in each group.During the treatment period,4 patients in the TCM group and 3 patients in the control group dropped out.The control group received conventional Guideline-directed medical therapy(GDMT),while the TCM group received GDMT plus Hongqi Shenmai Drink.The treatment course for both groups was 12 weeks.The TCM syndrome scores of the two groups of patients were compared before and after treatment,and the clini-cal efficacy and readmission rate were assessed.Echocardiography was used to assess cardiac structure and function.ELISA was used to detect changes in serum SPP1,N-terminal pro-brain natriuretic peptide(NT-proBNP),interleukin-1β(IL-1β),type Ⅰ collagen α1(COL1α1),and matrix metalloproteinase 9(MMP9)levels.The 6-minute walk test(6MWT)was used to assess exercise tolerance,and the Minnesota living with heart failure questionnaire(MLHFQ)was used to assess patients'quality of life.Adverse reactions were monitored in both groups during treatment.RESULTS After treatment,the TCM syndrome scores of both groups decreased signifi-cantly(P<0.01),with the TCM group showing a significantly lower score than the control group(P<0.01).The total effective rate of TCM clinical efficacy in the TCM group was superior to that in the control group(P<0.05),and the readmission rate in the TCM group was significantly lower than that in the control group(P<0.01).Left ventricular end diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),left ventricular ejection fraction(LVEF),6MWT,and MLHFQ scores improved in both groups(P<0.01),with the TCM group showing superior improvement compared to the control group(P<0.05,P<0.01).Serum levels of NT-proBNP,IL-1β,COL1α1,and MMP9 decreased in both groups(P<0.05,P<0.01).Serum SPP1 levels were significantly decreased in the TCM group(P<0.01),and serum levels of NT-proBNP,IL-1β,COL1α1,and MMP9 in the TCM group were significantly lower than those in the con-trol group(P<0.01).The change in SPP1(ΔSPP1)showed a negative correlation with the change in the cardiac function ΔLVEF(r=-0.42,P<0.01),and a positive correlation with the myocardial fibrosis marker ΔCOL1α1(r=0.58,P<0.01)and the matrix degradation marker ΔMMP9(r=0.51,P<0.01).There was no significant difference in adverse reaction rates between the two groups during treat-ment(P>0.05).CONCLUSION Hongqi Shenmai Drink combined with GDMT can effectively improve clinical symptoms and cardiac function in patients with AMI-HF of qi-yin deficiency and blood stasis type,with good safety.Its mechanism may be related to the in-hibition of SPP1-mediated inflammation-fibrosis pathway and the downregulation of IL-1β,COL1α1,and MMP9 expression.

Objective:To examine the association among childhood emotional neglect, thwarted belongingness, perceived burdensomeness, and depression in junior high school students.Methods:From October to December 2024, a total of 314 junior high school students were recruited in Dongying City, Shandong Province. The Chinese versions of the childhood trauma questionnaire-short form (CTQ-SF), the center for epidemiologic studies depression scale (CES-D), and the interpersonal needs questionnaire (INQ) were administered for investigation. SPSS 27.0 software was used for common-method bias test, descriptive analysis, difference test, and correlation analysis. Mplus 8.3 software was employed to build a structural equation model, and the Bootstrap method was adopted for mediation analysis.Results:The scores of depression, childhood emotional neglect, thwarted belongingness, and perceived burdensomeness in junior high school students were 14.00 (9.00, 24.00), 9.00 (5.00, 12.00), 13.00 (8.00, 18.00) and 8.00 (6.00, 19.25), respectively. All variables were positively correlated with one another ( r=0.33-0.51, P<0.01). The total effect of childhood emotional neglect on depression was 0.493 (95% CI=0.396-0.591). The direct effect was 0.126 (95% CI=0.013-0.240), accounting for 25.56%(0.126/0.493) of the total effect. The total indirect effect was 0.367 (95% CI=0.287-0.447), accounting for 74.44%(0.367/0.493) of the total effect. Specifically, the pathway " childhood emotional neglect → thwarted belongingness→ depression" yielded an effect of 0.109, and the pathway " childhood emotional neglect → perceived burdensomeness → depression" yielded an effect of 0.258. Conclusion:Thwarted belongingness and perceived burdensomeness play parallel mediating effects between childhood emotional neglect and depression in junior high school students.
