Objective: To statistically analyze the association between blood donation intervals and the incidence of adverse reactions to blood donation based on blood donor data from Shenzhen. Methods: Basic data and records of adverse reactions to blood donation among voluntary whole blood donors in Shenzhen from January 2017 to June 2025 were extracted. A total of 795 404 whole blood donations were recorded, including 502 743 from males and 292 661 from females, with 1 088 and 751 cases of adverse reactions, respectively. Analyses were performed using R software, including restricted cubic spline (RCS), binary logistic regression, and generalized estimating equations (GEE) to evaluate the correlation between donation intervals and adverse reactions. Results: A total of 1 839 cases of adverse reactions were recorded, accounting for 0.23% of the total donations. Both binary logistic regression analysis and the generalized estimating equations (GEE) model showed that there was no significant difference in the incidence of adverse reactions between male and female donors with an interval of ≥6 months compared to those with an interval of ≥3 months but<6 months. Furthermore, using the 3-5 month interval group as the reference, the analysis indicated that the incidence of adverse reactions significantly increased in males with a 9-12 month interval, while no statistically significant differences were observed across any of the female subgroups. Conclusion: There was no significant correlation between adverse reactions to blood donation and the donation interval. Compared with a donation interval of ≥6 months, an interval of<6 months does not lead to an increase in the incidence of adverse reactions among male or female donors. The findings of this study may help enhance the willingness of blood donors to participate.

Objective: To statistically analyze the association between blood donor age and the incidence of adverse reactions based on whole blood donor data from Shenzhen. Methods: Data on basic characteristics and records of adverse donation reactions among voluntary whole blood donors in Shenzhen from January 2017 to June 2025 were extracted. A total of 795 404 whole blood donations were recorded, including 502 743 from males and 292 661 from females, with 1 088 and 751 cases of adverse reactions, respectively. Analyses were performed using R software, including restricted cubic spline (RCS) analysis, binary logistic regression, and generalized estimating equations (GEE) to evaluate the correlation between donor age and adverse reactions. Results: A total of 1 839 cases of adverse reactions were recorded, accounting for 0.23% of the total donations. Both binary logistic regression and GEE model revealed that, compared with the≤55 years age group, the incidence of adverse reactions was reduced in both male and female donors in the >55 years age group, with the difference being statistically significant in males. Using the <23 years age group as a reference, the incidence of adverse reactions significantly decreased in both male and female donors across the 23-30, 31-40, 41-50, and 51-60 age groups, with the differences being statistically significant. Conclusion: There is a negative correlation between the rate of adverse donation reactions and age, with the incidence of such reactions among whole blood donors over 55 years old being no higher than that among donors aged 55 years or younger. These findings carry positive significance for safeguarding the donation rights of older donors and meeting clinical blood demand.

BackgroundThe mental health issues of medical staff have received increasing attention. Previous studies have mainly focused on the epidemiological characteristics and influencing factors， but there is a lack of sufficient understanding of the heterogeneity characteristics of the depression-anxiety symptoms network among medical staff. ObjectiveTo compare the differences in the depression-anxiety symptoms network between medical staff and community residents， so as to provide references for the promotion of the mental health of medical staff. MethodsFrom June 1， 2022 to December 31， 2024， a stratified random sampling method was used to recruit 1 959 medical staff from public hospitals and community health centers in 9 townships （industrial parks） of Dongguan City， Guangdong Province， as well as 2 412 community residents in this area， were selected as the research subjects. The general situation questionnaire， Patients' Health Questionnaire Depression Scale-9 item （PHQ-9）， and the Generalized Anxiety Disorder Scale-7 item （GAD-7） were used for investigation. The network visualization was conducted using the qgraph package of R 4.0.0. The centrality indicators of the network were calculated using the networktools package. The reliability of the network structure was evaluated using the bootnet package. The differences in the depression-anxiety symptoms network between medical staff and community residents were compared using the NetworkComparisionTest package. ResultsA total of 1 792 medical staff and 2 110 community residents completed the survey. The numbers of medical staff with mild， moderate and severe depressive symptoms were 381 （21.26%）， 217 （12.11%） and 169 （9.43%）， respectively， while the numbers of community residents were 322 （15.26%）， 98 （4.64%） and 66 （3.13%）， respectively. The numbers of medical staff with mild， moderate and severe anxiety symptoms were 411 （22.94%）， 126 （7.03%） and 93 （5.19%）， respectively， while the numbers of community residents were 320 （15.17%）， 73 （3.46%） and 18 （0.85%）， respectively. The comparison of the detection rates of depressive symptoms and anxiety symptoms between the two groups showed statistically significant differences （χ²=152.012， 205.953， P<0.01）. The network analysis results showed that the core symptom clusters of medical staff were "uncontrollable worry" "psychomotor retardation" "inability to relax"， and "depression"， while those of community residents were "uncontrollable worry" "inability to relax" "inferiority complex"， and "depression". There was a statistically significant difference in the network structure between the two groups （M=0.275， P<0.05）， and the overall connection strength of medical staff was lower than that of community residents （7.523 vs. 7.950， S=0.426， P<0.05）. ConclusionThe detection rates of depression and anxiety symptoms among medical staff were higher than those among community residents. The depression-anxiety symptoms network of medical staff was more concentrated， and the core symptoms were more prominent.［Funded by Social Development and Technology Project of Dongguan City （number， 20221800902552）］

Objective·To analyze the neurodevelopmental outcomes of children after end-to-side anastomosis for coarctation of the aorta(CoA).Methods·The surgical and neurological follow-up data were collected from children who underwent end-to-side anastomosis for CoA at Shanghai Children's Medical Center,Shanghai Jiao Tong University School of Medicine from January 1,2017 to December 31,2021.Neurological assessments included magnetic resonance imaging(MRI)and Griffiths Mental Development Scale assessments.Neurodevelopmental outcomes were evaluated using Griffiths Mental Development Scale.Clinical characteristics were compared between patients with normal and abnormal MRI and Griffiths Mental Development Scale results to assess the correlation between the two assessments and their association with cardiopulmonary bypass(CPB)use and CPB modality.Results·Twenty-seven children with isolated CoA or CoA combined with simple intracardiac anomalies were included.MRI results were available for 25 cases,with 5 showing abnormalities(20.0%).Griffiths Mental Development Scale results were available for 26 cases,with 21(80.77%)showing abnormal scores,including 18 in hearing and language,and 12 in performance.No significant correlation was found between abnormal MRI or Griffiths Mental Development Scale results and the use of CPB(P=0.341,P=1.000).Among patients who underwent CPB,those in the moderate hypothermia group accounted for the majority of cases without neurological abnormalities,with proportions of 80.00%(MRI)and 100.00%(Griffiths Mental Development Scale).Conclusion·Children undergone end-to-side anastomosis for CoA are at relatively high risk for neurodevelopmental abnormalities,particularly in hearing-language and performance domains.CPB may not be a direct risk factor for poor neurodevelopmental outcome,and moderate hypothermia during CPB may be neuroprotective.

Objective To analyze ancient prescriptions for knee osteoarthritis(KOA),and explore their application patterns,for providing clinical reference value.Methods Prescriptions were collected from ancient documents,and a database was created by using Excel 2016 for frequency analysis.Association rules and hidden structures were analyzed by using SPSS Modeler 18.0 and Lantern 5.0.Results A total of 373 prescriptions and 421 herbs were collected,with 3894 times of frequency of medication.Danggui was the most frequently used herb.Herbs primarily tonified deficiencies,relieved exterior symptoms,and expelled wind-dampness,with warm properties and pungent,sweet,or bitter tastes,mainly targeting the spleen and kidney meridians.Thirteen strong association rules were identified,including Chuanxiong+Niuxi-Danggui,and Bixie-Niuxi.Hidden structure analysis revealed 10 variables,leading to 4 clusters and 4 core prescriptions.Common syndromes included wind-damp,wind-cold-damp,wind-damp-heat,and qi-blood deficiency.Conclusion The treatment of KOA in ancient literature focuses on dispelling wind and removing dampness,taking into account both positive deficiency and evil excess,flexible use of tonifying spleen and kidney,clearing dampness-heat,tonifying Qi and blood and other drugs.

Purpose To explore the pathological characteristics,diagnosis,and differential diagnosis of pure ery-throid leukemia(PEL).Methods A retrospective analysis was conducted on the clinicopathological data of 12 cases of PEL.Immunohistochemical EnVision method and flow cytometry were used to detect PEL-related immune markers,and heat-treated Giemsa R-banding technique was applied to analyze the chromosomal karyotype.Results Peripheral blood and bone marrow smears revealed that 2 out of 7 cases showed presence of proerythroblast in peripheral blood,and 7 out of 12 cases showed atypical proerythroblast in bone marrow samples.After recounting,the average percentage of proerythroblast in the 12 PEL cases was 36.8％(ranging from 2％to 69.5％),with an average of 53.2％of all er-ythroid cells(ranging from 5％to 88％).Among them,9 cases did not meet the diagnostic criteria for PEL.Bone marrow biopsy:11 cases showed hypercellularity,with tumor cells showing diffuse proliferation in 9 cases,accompa-nied by dysplasia of megakaryocytes in 7 cases,and there was increased proliferation of fibrous tissue in 9 cases.Im-munohistochemistry:12 cases exhibited strong staining intensity for CD71 and E-cadherin.11 cases expressed CD117,while 4 cases expressed CD34,3 cases exhibited slight expression of GPA,and 1 case weakly expressed CD61.Flow cytometry:in 8 cases,there was an increased proportion of early-stage erythroid cells,accounting for 3.1％to 80.31％of nucleated cells,with an average of 31.0％.All cases expressed CD117 and CD71 to varying degrees,with 7 out of 8 cases expressing CD36,5 out of 7 cases expressing CD105,and 3 out of 4 cases expressing GPA.A few ca-ses demonstrated aberrant expression of CD123 and CD7.Chromosomal Karyotyping:7 cases exhibited highly complex karyotypes(7/8),with frequent involvement of chromosomes 5,7,8,17,and 19.One case had a normal karyotype.Conclusion The diagnosis of PEL requires a comprehensive assessment combining various methods including bone marrow smears,bone marrow biopsy,immunohistochemistry,and flow cytometry.

This paper analyzes the characteristics of highly cited papers published in Chinese Clinical Pharmacology and Therapeutics in the past ten years,in order to explore the influence and re-search value of these papers.Highly cited papers are an important index to evaluate the scientific re-search level of scholars and research institutions,so this study focuses on the characteristics of their number,citation frequency,number of co-authors and regional distribution.The paper uses bibliomet-rics to analyze the publication trend and citations of highly cited papers.The results show that during the observation period,the number of highly cited papers decreases year by year,and there is a signifi-cant correlation between cited frequency and publi-cation time.In addition,the number of co-authors presents a normal distribution,among which the number of co-authors is the largest,indicating that moderate cooperation has a positive effect on the influence of papers.From the perspective of geo-graphical distribution,the author group of the mag-azine is relatively dispersed,covering many regions of the country,among which Anhui,Hunan and Zhejiang have become the main sources of high-quality manuscripts.The finding reflects the maga-zine's wide reach across the country.The results of this study provide empirical support for under-standing the characteristics of highly cited papers and emphasize the importance of research collabo-ration and geographical factors in research publica-tion.Through the analysis of highly cited papers,this paper provides references for subsequent re-searchers in selecting research topics and coopera-tion methods,and also provides beneficial sugges-tions for improving the research level and influence of clinical pharmacology in China.

Meckel′s cartilage (MC) was first delineated in 1820 by the German anatomist Johann Friedrich Meckel the Younger through his examination of human embryos. During early development, MC functions as a supportive structure for the mandible and serves as a template for the subsequent formation of the jaw bones. Ultimately, MC transforms into either skeletal tissue, ligaments, or completely resorbs, integrating with the continuously developing osseous structures. This review elucidates the influence of MC development and degeneration on mandibular morphogenesis, delineating cellular processes and key factors that govern chondrogenic fate determination. The analysis reveals how the alterations of MC affect mandibular and craniofacial development. As a transient cartilaginous structure, investigation into MC may yield valuable insights for understanding oral and craniomaxillofacial pathologies.
