Objective: To investigate the exposure to television advertising of sugar sweetened beverages and the use of persuasive marketing techniques among children and adolescents in Beijing, so as to provide evidence for reduing childrens intake of sugar sweetened beverages. Methods: From October 19, 2020 to November 16, 2021, 32 days were randomly selected. The top four popular channels of children and adolescents aged 3-18 years were defined. Each channel was monitored from 6:00:00 to 23:59:59 for each date. A total of 2 304 h was recorded. Advertisements involving sugar sweetened beverages broadcast before, during or after the program were included. The frequency and the use of persuasive marketing techniques were analyzed. Results: A total of 1 237 advertisements for sugar sweetened beverages were included, of which 50.93% were dairy beverages, 28.38% were teabased beverages, and 19.48% were vegetable protein beverages. The average frequency of sugar sweetened beverages advertisements on every channel was (0.62±1.29)piece/h. The frequency of sugar sweetened beverages advertisements on every local channel [(1.04±1.35)piece/h] and childrens channel [(1.11±1.61)piece/h] was separately higher than every national channel [(0.48±1.24)piece/h] and general channel [(0.12±0.48)piece/h] (t=-14.05, 31.64, P<0.01). There were seasonal differences in television advertising of sugar sweetened beverages, and were more frequent during lunch and dinner times. The most frequently used persuasive marketing techniques were "images of children" (74.54%), "nutritional message" (61.76%), "product composition details" (58.61%), "nutrition claim" (57.24%), and "nutrition function claim or other function claim" (53.11%). Conclusions Children and adolescents are often exposed to television advertisement of sugar sweetened beverages on childrens channels and during meal times. There is an urgent need to formulate relevant policies to regulate the marketing of sugar sweetened beverages advertisement and reduce children and adolescents intake.

Objective:To explore the application value of reticulocyte hemoglobin equivalent(Ret-He)for diagnosing latent iron deficiency in female plateletpheresis donors.Methods:A total of 230 female plateletpheresis donors in Fujian Blood Center from January to February 2022 were selected as the research group and divided into three groups:normal group,iron depletion(ID)group and iron deficient erythropoiesis(IDE)group,according to the severity of iron deficiency.The level of hemoglobin(HGB),mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH),coefficient of variation of red cell distribution width(RDW-CV)and Ret-He were measured by using the Sysmex XN automated hematology analyzer.Chemiluminescence immunoassay was used to detect iron biochemical indexes.Receiver operating characteristic(ROC)curve analysis was performed to evaluate the diagnosic value of relevant indicators in female blood donors with latent iron deficiency.Results:Ret-He in ID group was 32.55(31.15,33.10)pg,which was significantly lower than that in the normal group[33.80(32.73,34.70)pg](P＜0.05),and significantly higher than that in IDE group[30.40(28.70,31.50)pg](P＜0.05).ROC analysis in diagnosis of IDE demonstrated that the area under the curves(AUCs)of HGB,MCV,MCH,RDW-CV and Ret-He were 0.892,0.843,0.909,0.890,0.931,respectively.When the critical value of Ret-He was 32.05 pg,its sensitivity and specificity were 85.90％and 92.60％,respectively.However,all red blood cell parameters had poor diagnostic value for ID.Conclusion:Ret-He is a perfect predictor for latent iron deficiency in female blood donors.Detection of Ret-He can advance the diagnosis of iron deficiency in female blood donors to the IDE stage.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To explore a definition of healthy longevity in the Chinese population based on the Delphi method.Methods:Through a comprehensive literature review and expert consultation, the dimensions in the definition of healthy longevity were identified, and a preliminary list of questions was created. Experts in clinical medicine, public health, basic research, and the elderly care service industry, who had been working in the field of geriatric health for at least 5 years, were invited to participate in the Delphi survey from August to December 2022. The survey questionnaires were administered via email in two rounds, and experts were asked to select the optimal options from the provided questions. The active coefficients were expressed by the response rate, and a consensus was reached when the largest number of experts agreed for single-choice questions and more than 70% agreed for multiple-choice questions.Results:In the two rounds, the active coefficients were 96.00% (24/25) and 79.17% (19/24), respectively, and a consensus was finally reached on nine items, including age, physical health, common metabolic indicators, mental health, cognitive function, functional ability, social activity, self-rated health, and subjective well-being. Following discussions among the research team and experts, a final definition of healthy longevity was determined. Healthy longevity could refer to a state of good physical, psychological, cognitive function and social adaptation, as well as subjective well-being, in individuals aged 90 and above. Specifically, individuals with healthy longevity should be free from diseases associated with high disability rates and mortality, such as stroke, cancer, and Parkinson′s disease. They should also maintain reasonable levels of common non-communicable disease indicators, such as blood pressure and blood glucose, and exhibit favorable mental health and cognitive function using validated measurement tools. In addition, individuals with healthy longevity should engage in social interactions with friends and relatives, care for family members, and go out to do things. Meanwhile, with the ability to complete the visual and hearing functions of daily life and communication, and the ability to complete basic activities such as walking, eating, bathing, toileting, dressing, continence of urination, and bowel movement independently, they could rate themselves to be in good health and experience a relatively high level of life satisfaction.Conclusion:A definition of healthy longevity in the Chinese population is established through the two-round Delphi consultation.

Objective:To explore the implementation strategies for promoting healthy longevity among the elderly population in China based on the Delphi method.Methods:Through literature review and expert discussion, a framework for implementation strategies to achieve healthy longevity among the elderly was determined, and a preliminary checklist of implementation strategies was developed. The Delphi method was employed from August to December 2022, inviting 25 experts from various disciplines such as clinical medicine, public health, basic research, and the elderly care services industry. Experts were sent consultation questionnaires via email to assess the importance, feasibility, judgment basis and familiarity of each implementation strategy. Active coefficient, authority coefficient, and harmony coefficient were analyzed to ultimately determine the important and feasible implementation strategies for healthy longevity that were suitable for the Chinese elderly population.Results:The expert active coefficients of the two rounds were 96.00% (24/25) and 79.17% (19/24). The authority coefficients were (0.76±0.19) and (0.77±0.17). The average scores of importance were (4.32±0.84) and (4.36±0.82), and the corresponding scores of feasibility were (3.72±1.04) and (3.80±0.92). The harmony coefficients for the importance score were 0.269 ( χ 2=594.084, P<0.001) and 0.159 ( χ 2=193.624, P<0.001). The harmony coefficients for feasibility scores were 0.205 ( χ 2=452.008, P<0.001) and 0.167 ( χ 2=202.878, P<0.001). The final eight implementation strategies were identified after two rounds of consultation. Conclusion:Through two rounds of Delphi consultations, eight important and feasible implementation strategies for promoting healthy longevity that are suitable for the Chinese context have been proposed.

OBJECTIVE: To investigate the correlation of iron metabolic parameters with platelet counts in blood donors. METHODS: A total of 400 blood donors who met requirements of apheresis platelet donation were collected, and their hematological parameters were analyzed. The donors were divided into low ferritin group and normal group, the differences of hematological parameters between the two groups were compared, and the correlation of iron metabolic parameters and routine hematology parameters with platelet counts were analyzed. RESULTS: Whether male or female, low ferritin group had higher platelet counts than normal group (P < 0.01). Among the iron metabolic parameters, the platelet counts was negatively correlated with serum ferritin (SF), serum iron (SI), and transferrin saturation (TSAT) (r =-0.162, r =-0.153, r =-0.256), and positively correlated with total iron binding capacity (TIBC) and unsaturated iron binding capacity (UIBC) (r =0.219, r =0.294) in female blood donors. Platelet counts was also negatively correlated with SF, SI and TSAT (r =-0.188, r =-0.148, r =-0.224) and positively correlated with UIBC (r =0.220) in male blood donors. Among the routine hematology parameters, platelet counts was negatively correlated with mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and reticulocyte hemoglobin equivalent (Ret-He) in female blood donors (r =-0.236, r =-0.267, r =-0.213, r =-0.284). Platelet counts was also negatively correlated with MCH, MCHC and Ret-He in male blood donors (r =-0.184, r =-0.221, r =-0.209). CONCLUSION In blood donors with low C-reactive protein level, the lower the iron store capacity, the lower the iron utilization, and the platelet counts tends to rise.

Objective: To describe the gene mutation profile of newly diagnosed pediatric B-acute lymphoblastic leukemia (B-ALL) and analyze its effect on minimal residual disease (MRD). Methods: A total of 506 newly diagnosed B-ALL children treated in Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences from September 2018 to July 2021 were enrolled in this retrospective cohort study. The enrolled children were divided into MRD ≥1.00% group and <1.00% group according to MRD results on the 19th day since chemotherapy, and MRD ≥0.01% group and <0.01% group according to MRD results on the 46th day. Clinical characteristics and gene mutations of two groups were compared. Comparisons between groups were performed with chi-square test or Fisher's exact test. Independent risk factors of MRD results on the 19th day and the 46th day were analyzed by Logistic regression model. Results: Among all 506 patients, there were 318 males and 188 females. On the 19th day, there were 114 patients in the MRD ≥1.00% group and 392 patients in the MRD <1.00% group. On the 46th day, there were 76 patients in the MRD ≥0.01% group and 430 patients in the MRD <0.01% group. A total of 187 gene mutations were detected in 487 (96.2%) of 506 children. The most common gene mutations were signal transduction-related KRAS gene mutations in 111 cases (22.8%) and NRAS gene mutations in 99 cases (20.3%). Multivariate analysis showed that PTPN11 (OR=1.92, 95%CI 1.00-3.63), KMT2A (OR=3.51, 95%CI 1.07-11.50) gene mutations and TEL-AML1 (OR=0.48, 95%CI 0.27-0.87), BCR-ABL1 (OR=0.27, 95%CI 0.08-0.92) fusion genes and age >10 years (OR=1.91, 95%CI 1.12-3.24) were independent influencing factors for MRD ≥1.00% on the 19th day. BCORL1 (OR=2.96, 95%CI 1.18-7.44), JAK2 (OR=2.99, 95%CI 1.07-8.42) and JAK3 (OR=4.83, 95%CI 1.50-15.60) gene mutations and TEL-AML1 (OR=0.43, 95%CI 0.21-0.87) fusion gene were independent influencing factors for MRD ≥0.01% on the 46th day. Conclusions: Children with B-ALL are prone to genetic mutations, with abnormalities in the RAS signaling pathway being the most common. Signal transduction related PTPN11, JAK2 and JAK3 gene mutations, epigenetic related KMT2A gene mutation and transcription factor related BCORL1 gene mutation are independent risk factors for MRD.
