【Objective】 To establish an effective quality indicator monitoring system, scientifically and objectively evaluate the quality management level of blood banks, and achieve continuous improvement of quality management in blood bank. 【Methods】 A quality monitoring indicator system that covers the whole process of blood collection and supply was established, the questionnaire of Quality Monitoring Indicators for Blood Collection and Supply Process with clear definition of indicators and calculation formulas was distributed to 17 blood banks in Shandong. Statistical analysis of 21 quality monitoring indicators in terms of blood donation service (10 indicators), blood component preparation (7 indicators ), and blood supply (4 indicators) from each blood bank from January to December 2022 were conducted using SPSS25.0 software The differences in quality monitoring indicators of blood banks of different scales were analyzed. 【Results】 The average values of quality monitoring indicators for blood donation service process of 17 blood banks were as follows: 44.66% (2 233/5 000) of regular donors proportion, 0.22% (11/50) of adverse reactions incidence, 0.46% (23/5 000) of non-standard whole blood collection rate, 0.052% (13/25 000) of missed HBsAg screening rate, 99.42% (4 971/5 000) of first, puncture successful rate, 86.49% (173/200) of double platelet collection rate, 66.50% (133/200) of 400 mL whole blood collection rate, 99.25% (397/400) of donor satisfaction rate, 82.68% (2 067/2 500) of use rate of whole blood collection bags with bypass system with sample tube, and 1 case of occupational exposure in blood collection.There was a strong positive correlation between the proportion of regular blood donors and the collection rate of 400 mL whole blood (P<0.05). The platelet collection rate, incidence of adverse reactions to blood donation, and non-standard whole blood collection rate in large blood banks were significantly lower than those in medium and small blood banks (P<0.05). The average quality monitoring indicators for blood component preparation process of 17 blood banks were as follows: the leakage rate of blood component preparation bags was 0.03% (3/10 000), the discarding rate of lipemic blood was 3.05% (61/2 000), the discarding rate of hemolysis blood was 0.13%(13/10 000). 0.06 case had labeling errors, 8 bags had blood catheter leaks, 2.76 bags had blood puncture/connection leaks, and 0.59 cases had non-conforming consumables. The discarding rate of hemolysis blood of large blood banks was significantly lower than that of medium and small blood banks (P<0.05), and the discarding rate of lipemic blood of large and medium blood banks was significantly lower than that of small blood banks (P<0.05). The average values of quality monitoring indicators for blood supply process of 17 blood banks were as follows: the discarding rate of expired blood was 0.023% (23/100 000), the leakage rate during storage and distribution was of 0.009%(9/100 000), the discarding rate of returned blood was 0.106% (53/50 000), the service satisfaction of hospitals was 99.16% (2 479/2 500). The leakage rate of blood components during storage and distribution was statistically different with that of blood component preparation bags between different blood banks (P<0.05). There were statistically significant differences in the proportion of regular blood donors, incidence of adverse reactions, non-standard whole blood collection rate, 400 mL whole blood collection rate, double platelet collection rate, the blood bag leakage rate during preparation process, the blood components leakage rate during storage and distribution as well as the discarding rate of lipemic blood, hemolysis blood, expired blood and returned blood among large, medium and small blood banks (all P<0.05). 【Conclusion】 The establishment of a quality monitoring indicator system for blood donation services, blood component preparation and blood supply processes in Shandong has good applicability, feasibility and effectiveness. It can objectively evaluate the quality management level, facilitate the continuous improvement of the quality management system, promote the homogenization of blood management in the province and lay the foundation for future comprehensive evaluation of blood banks.

Objective:To compare the prognostic value of two predictive models based on C-reactive protein(CRP)and albumin(ALB),namely the CRP to ALB ratio(CAR)and the Glasgow prognostic score(GPS),in newly diagnosed patients with diffuse large B-cell lymphoma(DLBCL).Methods:The data of newly diagnosed DLBCL patients admitted to our center from May 2014 to January 2022 were reviewed.A total of 111 patients who completed at least 4 cycles of R-CHOP or R-CHOP-like chemotherapy with detailed clinical,laboratory data and follow-up information were included.The receiver operating characteristic(ROC)curve was performed to evaluate the predictive value of pre-treatment CAR on disease progression and survival.Furthermore,the association between CAR and baseline clinical,laboratory characteristics of patients was evaluated,and progression-free survival(PFS)and overall survival(OS)were compared between different CAR and GPS subgroups.Finally,the univariate and multivariate COX propor-tional hazard regression models were used to analyze the factors affecting disease outcomes.Results:ROC curve showed that the area under the curve(AUC)of CAR predicting PFS and OS in DLBCL patients was 0.687(P=0.002)and 0.695(P=0.005),respectively,with the optimal cut-off value of 0.11 for both predicting PFS and OS.Compared with the lower CAR(＜0.11)group,the higher CAR(≥0.11)group had more clinical risk factors,including age＞60 years(P=0.025),ECOG score ≥2(P=0.004),Lugano stage Ⅲ-Ⅳ(P＜0.001),non-germinal center B-cell-like(non-GCB)subtype(P=0.035),elevated lactate dehydrogenase(LDH)(P＜0.001),extranodal involved site＞1(P=0.004)and IPI score＞2(P＜0.001).The interim response evaluation of patients showed that the overall response rate(ORR)and complete response rate(CRR)in the lower CAR group were both significantly better than those in the higher CAR group(ORR:96.9％vs 80.0％,P=0.035;CRR:63.6％vs 32.5％,P=0.008).With a median follow-up of 24 months,patients with lower CAR had significantly longer median PFS and OS than those with higher CAR(median PFS:not reached vs 67 months,P=0.0026;median OS:not reached vs 67 months,P=0.002),while there was no statistical difference in PFS(P=0.11)and OS(P=0.11)in patients with GPS of 0,1,and 2.Multivariate Cox regression analysis indicated that only sex(male)and IPI score＞2 were independent risk factors for both PFS and OS.Conclusion:CAR is significantly correlated with disease progression and survival in DLBCL patients;And compared with GPS,CAR has more advantages in predicting disease outcomes in DLBCL patients.

Objective:To compare the efficacy and safety of flumatinib (FM)and imatinib (IM)as first-line treatment in newly-diagnosed patients with chronic myeloid leukemia in chronic phase (CML-CP ) in real world. Methods:A total of 84 newly-diagnosed CP-CML patients in our center from December 2019 to December 2022 were retrospectively analyzed.Among them,32 cases received FM as first-line treatment,and 52 cases received IM. Molecular response (MR),disease progression,survival and incidence of adverse events (AEs)were compared between the two groups.Results:At 3 months of treatment,the incidences of early molecular response (EMR ),MR2.0 and MR3.0 were 96.7％,70.0％ and 20.0％ in FM group,respectively,which were significantly higher than 77.1％,29. 2％ and 0 in IM group (all P<0.05 ).At 6,9 and 12 months of treatment,the incidences of major molecular response (MMR)in FM group were 68.2％,85.7％ and 90.0％,respectively,which were significantly higher than 22.9％,34.0％ and 51.1％ in IM group (all P<0.01).The median time to achieve MMR in FM group was 6(6-9)months,which was significantly shorter than 18(12-22)months in IM group (P<0.001 ).The 3-year progression-free survival rate and 3-year event-free survival rate in FM group were 100％ and 68.8％,respectively,while in IM group were 98.1％ and 55.8％.There were no significant differences between the two groups (P>0.05). The incidence of grade 3-4 hematologic AEs in FM group was 21 .9％,which was slightly lower than 25.0％ in IM group,but the difference was not significant (P>0.05 ).Conclusion:In real clinical practice,FM as first-line treatment achieves MMR earlier than IM,and exhibits good safety profile in newly-diagnosed CML-CP patients,which potentially leads to improved long-term survival and treatment-free remission.

Objective:To estimate the costs of dementia from a societal perspective in Tongliao City and ex-plore the influencing factors of these costs.Methods:Dementia was diagnosed using the 10/66 Dementia Research Group assessment instruments.Data on healthcare utilization,caregiver's care time or costs,and the distress due to caregiving were collected.The cost-proportion conversion method was used to estimate the per capita cost of health services based on data from the National Statistical Yearbook.The human capital approach was used to estimate the unit value of informal care time,and the willingness-to-pay method was used to measure the intangible costs of car-egivers.The total societal costs of dementia were calculated based on the reference year 2023,and a two-part model was employed to analyze the factors influencing the societal costs.Results:A total of 390 dementia patients were di-agnosed,with an average societal cost per capita of 117 877 Yuan.The largest cost component was informal care provided by unpaid family members,accounting for 73.1％of the total societal cost.The societal costs for female patients were 61 395 Yuan higher than those for male patients.Patients with comorbid stroke had a higher societal cost of 63 008 Yuan compared to patients without stroke,and each additional chronic disease added 5 868 Yuan to societal costs.Additionally,each non-memory dimension impairment in the Clinical Dementia Rating Scale in-creased the societal costs by 53 997 Yuan.Conclusion:Dementia poses a significant socio-economic burden,with informal care being the major component of this burden.

Objectives: This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition.The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach. Methods: A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and anti resorptive agents in sequential therapy approaches. Results: The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to anti resorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for in dividuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment. Conclusions This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.
