Objective: To evaluate the methodological quality and reporting quality of clinical practice guidelines or expert consensus on blood transfusion and blood use (BTBU) in China (hereinafter referred to as "guidelines/consensus"), providing reference for the development and updating of future BTBU guidelines/consensus. Methods: A systematic search was conducted in Chinese databases such as China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Data-base, relevant guideline release platforms, and professional association websites. BTBU-related guidelines/consensus published between January 2006 and December 2025 were included. According to the inclusion and exclusion criteria, after completing literature screening and data extraction, three evaluators independently assessed the quality of the included literature using the Scientificity, Transparency, and Applicability of Guidelines Rating Tool (STAR), the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ), and the International Practice Guideline Reporting Standards (RIGHT). Results: A total of 29 documents were included, including 5 guidelines, 22 consensus statements, and 2 protocols. The results of the STAR assessment showed that the total score was (21.7±8.8)%. The domain score ratios for registration, research protocol, funding, working group, conflict of interest, clinical question, evidence, consensus method, recommendation, accessibility and other domains were (2.2±12.1)%, 0, (36.7±25.1)%, (18.3±7.6)%, (19.2±15.3)%, (16.6±23.1)%, (15.1±6.3)%, (9.6±21.2)%, (54.3±18.4)%, (31.7±10.4)% and (10.3±31.0)%, respectively. For the AGREE Ⅱ assessment, the methodological quality of 26 articles was rated Grade B and 3 articles Grade C. The results of the RIGHT assessment indicated that the overall reporting rate of all guidelines/consensuses was (65.3±4.0)%. Conclusion: The methodological and reporting quality of current expert guidelines/consensus on BTBU in China still need improvement, and guidelines and consensus should be strictly formulated and standardized according to the standards of STAR, AGREE II and RIGHT.

Objective:To explore the clinical characteristics and healthcare burden in patients with McCune-Albright syndrome (MAS).Methods:A cross-sectional study was conducted at the Children′s Hospital, Zhejiang University School of Medicine. Clinical and healthcare burden data were systematically collected through structured questionnaires in 164 children with MAS from February 2022 to May 2023. According to the clinical characteristics, patients were categorized into 3 groups: monosymptomatic, bisymptomatic and trisymptomatic groups. Patients were also divided into 3 groups according to the age of <7, 7-<10 and 10-18 years. Comparative analyses of clinical characteristics and healthcare burden were conducted across age, sex, and symptom categories.Results:The cohort comprised 59 males (36.0%) and 105 females (64.0%) with an age of 4.6 (2.0, 7.4) years. Age stratification revealed 117 cases (71.3%) aged 0-<7 years, 29 cases (17.7%) aged 7-<10 years, and 18 cases (11.0%) aged 10-<18 years. Among monosymptomatic (67 cases, 40.9%), the cohort comprised 32 females (47.8%) and 35 males (52.2%), predominantly presenting with fibrous dysplasia (57 cases, 85.1%). This subgroup showed peak prevalence in the 0-<7 years age range (29 cases (50.9%)). The bisymptomatic cohort (56 cases, 34.1%) consisted of 39 females (69.6%) and 17 males (30.4%), predominantly manifesting fibrous dysplasia with skin hyperpigmentation (25 cases, 44.6%). Peak prevalence occurred in the 0-<7 years subgroup(16 cases (64.0%)). The trisymptomatic cohort (41 cases, 25.0%) consisted of 34 females (82.9%) and 7 males (17.1%), with peak prevalence occurring in the 0-<7 years subgroup (36 cases (87.8%)). The diagnostic journey analysis revealed 94 cases (57.3%) required 1-3 referrals, and 34 cases (20.7%) necessitated >3 referrals from symptom onset to definitive diagnosis. Healthcare expenditure analysis revealed 69 families (42.1%) incurred direct medical costs of 10 000-100 000 CNY, with 11 families (6.7%) exceeding >100 000 CNY. Direct non-medical costs reached of 10 000-100 000 CNY for 62 families (37.8%) and >100 000 CNY for 4 families (2.4%). Productivity loss affected 58 families (35.4%) at 10 000-100 000 CNY and 8 families (4.9%) above 100 000 CNY during the study period.Conclusion:MAS requires increased attention to skeletal manifestations, especially in children aged 0-<7 years. Moreover, the significant financial burden on families necessitates a society-wide support system.

Objective:To determine the prevalence and associates of hyperuricemia (HUA) among the middle- and older-aged population of the island and mountainous areas in Taizhou City of Zhejiang Province.Methods:A cross-sectional study was conducted on individuals aged 45 and above in the island and mountainous area of Taizhou City. The study included questionnaires, physical examinations, and laboratory tests. Data were primarily collected on sociodemographic characteristics, chronic disease history, lifestyle factors, waist circumference, blood pressure, and serum uric acid levels. The association between hyperuricemia and these factors was analyzed by logistic regression.Results:A total of 971 individuals were included in the study, comprising 468 from island and 503 from mountainous area. The prevalence of hyperuricemia was 17.9%, with a significantly higher prevalence in the island area (25.6%) compared to the mountainous area (10.7%). Stratified by gender and age, differences in the prevalence of hyperuricemia between island and mountainous areas were observed in males aged 55 to 64, females aged 45 to 54, 55 to 64, 75 and above (all P<0.05). Multiple logistic regression analysis showed that high intake of sea food (>3 times/week) was positively associated with hyperuricemia ( OR=2.10, 95% CI:1.33-3.34). Furthermore, separate regionally stratified logistic regression analyses showed that in the island area, male gender ( OR=3.15, 95% CI:1.78-5.66), central obesity ( OR=2.38, 95% CI:1.46-3.93), and hypertriglyceridemia ( OR=2.00, 95% CI:1.22-3.30) were positively correlated with hyperuricemia (all P<0.05). In the mountainous area, the age group of 65 and above ( OR=3.50, 95% CI:1.09-12.50), male ( OR=6.79, 95% CI:2.87-17.81), those employed in enterprises and institutions ( OR=6.57, 95% CI:1.92-23.73) and hypertension ( OR=3.68, 95% CI:1.66-8.87) were positively correlated with hyperuricemia (all P<0.05). Conclusions:The prevalence of hyperuricemia among the middle- and older-aged population in the island of Taizhou City is significantly higher than that in the mountainous areas. Targeted comprehensive behavioral interventions such as routine screening of chronic diseases, low-fat diet, alcohol control, reduced seafood intake, enhanced exercise, weight management, and blood pressure control are warranted.

Objective To evaluate the therapeutic effect of Shenfu injection in shock patients by using bedside critical ultrasound.Methods A total of 80 shock patients admitted to First Hospital of Nanchang from January 2022 to May 2024 were selected and divided into Shenfu group(45 cases)and control group(35 cases)according to whether Shenfu injection was applied.Patients in control group were given conventional western medical treatment,while patients in Shenfu group were treated with Shenfu injection in addition to control group.The ultrasound measurement indicators and clinical results were recorded on the 1st,3rd,and 7th days of treatment respectively,and left ventricular end diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF),peak velocity of early diastolic flow of mitral valve(E)/peak velocity of early diastolic motion of mitral annulus(E'),tricuspid annular plane systolic excusion(TAPSE),right ventricular fractional area change(RVFAC),inferior vena cava variation rate(IVCV),heart rate(HR),mean arterial pressure(MAP),N-terminal pro-brain natriuretic peptide(NT-proBNP),lactic acid(Lac),sequential organ failure assessment(SOFA)score and 30-day survival status of two groups of patients was compared.Results After 1 day,3 days and 7 days of treatment,LVEDD and E/E'of two groups of patients gradually decreased,while LVEF,TAPSE,RVFAC and IVCV gradually increased significantly(P＜0.05).After 7 days of treatment,the LVEF,TAPSE,RVFAC and IVCV of patients in Shenfu group were significantly higher than those in control group(P＜0.05).After 7 days of treatment,the HR,NT-proBNP,Lac and SOFA scores of two groups of patients were significantly lower than those before treatment in same group,and the MAP was significantly higher than that before treatment in same group(P＜0.05).The HR,NT-proBNP,Lac and SOFA scores of patients in Shenfu group were significantly lower than those in control group,the MAP was significantly higher than that in control group,and the mechanical ventilation time and the length of stay in intensive care unit were significantly shorter than those in control group(P＜0.05).Kaplan-Meier survival analysis showed that 30-day survival rate of patients in Shenfu group was significantly higher than that in control group(82.22％vs.54.28％,P＜0.05).Conclusion Bedside critical ultrasound showed that Shenfu injection could effectively improve ventricular systolic and diastolic function in shock patients,providing a valuable real-time assessment tool for shock treatment.

Objective:To analyze the changes and structural variations in hospitalization costs for patients with lung malignancies after the implementation of diagnosis-intervention packet (DIP) payment system, and to evaluate its effectiveness.Methods:Data from the first page of medical records and hospitalization cost data from the hospital information system of a tertiary general hospital in Henan Province were extracted for patients diagnosed with lung malignancies from 2020 to 2023. The data were divided into pre-implementation group (2020—2021) and post-implementation group (2022—2023) based on the implementation time of DIP. Chi-square test, t test, and Wilcoxon rank-sum test were used to analyze the differences in basic characteristics and hospitalization costs of patients with lung malignancies before and after the implementation of DIP. Grey relational analysis was employed to examine the internal associations between total hospitalization costs and various cost components. Structural variation analysis was used to assess the changes in the structure of hospitalization costs after the implementation of DIP. Results:A total of 14 587 hospitalized patients with lung malignancies were included, with 6 807 cases in the pre-implementation group and 7 780 cases in the post-implementation group. The average length of hospital stay decreased from (13.17±6.74) days before implementation to (12.02±6.49) days after implementation ( P<0.05). The proportion of level-four surgeries increased from 46.4% to 57.0% ( P<0.05). The average hospitalization cost per patient with lung malignancies decreased from 56 952 yuan before DIP implementation to 55 560 yuan after implementation ( P<0.05). For patients with lung malignancies diagnosed as C34.1, C34.2, C34.3, and C34.8, the top four cost components most strongly associated with total hospitalization costs were treatment costs, material costs, comprehensive medical service costs, and diagnostic costs, with correlation coefficients all>0.80. For patients with C34.9, the top four cost components most strongly associated with total hospitalization costs were treatment costs, comprehensive medical service costs, diagnostic costs, and Western medicine costs, with correlation coefficients>0.95. For patients diagnosed as C34.1, C34.2, C34.3, and C34.9, diagnostic costs, Western medicine costs, and material costs contributed significantly to the structural variation of hospitalization costs, with contribution rate of structure variation all exceeding 75%, among which Western medicine costs and material costs showed negative variation. For patients diagnosed as C34.8, treatment costs, Western medicine costs, and material costs contributed significantly to the structural variation of hospitalization costs, with contribution rate of structure variation all exceeding 80%, among which Western medicine costs showed negative variation. Conclusions:The implementation of DIP reduced the hospitalization costs for patients with lung malignancies, optimized the structure of hospitalization costs, improved the efficiency of medical services, and promoted the rational allocation of medical resources.

Objective To develop a new biological age model based on the National Health and Nutrition Examination Survey(NHANES)database and evaluate its predictive performance for mortality outcomes.Methods After excluding pregnant women and those with incomplete clinical data,a total of 8 234 participants aged 20～79 years from NHANES 2007-2010 were included and assigned into a testing set,and another 17 522 non-pregnant participants(17～79 years old)subjected from NHANESⅢ were enrolled and served as a training set to construct the new biological age(new Bioage)model.Multiple linear regression was used to construct models for new Bioage and age-adjusted biological age(new-agefixed Bioage),and other types of biological ages were calculated.Pearson correlation analysis was performed to assess the correlation between biological age and chronological age.Based on new-agefixed Bioage,biological age acceleration was calculated,and then according to the results,the participants were divided into accelerated biological aging group(biological age acceleration≥0,n=3 884)and decelerated biological aging group(biological age acceleration<0,n=4 350).Weighted data comparisons were conducted using the survey package in R,and Cox regression analysis was used to assess the impact of biological age acceleration on the mortality of the participants.Receiver operating characteristic(ROC)curve was plotted to determine the effect of new-agefixed Bioage and biological age acceleration on the area under the curve(AUC)for the mortality.Results The new-agefixed Bioage model,composed of 9 variables,had the highest AUC value(AUC=0.889 2,P<0.001)in predicting mortality outcomes and showed high correlation with chronological age and other biological ages.The decelerated biological aging group had significantly larger proportions of males,whites,education level of high school or higher,middle to high household income,married(or with a partner),engaging in physical activity,having private insurance,and cancer(P<0.05),lower BMI,slower biological age acceleration level,and less proportions of smokers,hypertension,diabetes,cardiovascular disease,and chronic obstructive pulmonary disease when compared with the accelerated biological aging group(P<0.05).Cox regression analysis indicated that,compared to the decelerated biological aging group,the accelerated biological aging group had a significantly increased risk of mortality in Model3[adjust for age group,gender,race,BMI,education level,household income,married(or with a partner),smoking status,heavy alcohol consumption,insurance status,physical activity,hypertension,diabetes,cardiovascular disease,chronic obstructive pulmonary disease,and cancer](HR=1.62,95%CI:1.28-2.06,P<0.001).ROC curve analysis revealed that new-agefixed Bioage significantly increased the AUC values(AUC=0.781,P<0.001;AUC=0.731,P<0.001)for middle-aged and elderly populations,while biological age acceleration significantly improved the AUC values(AUC=0.756,P<0.001)for the middle-aged population.Conclusion The new-agefixed Bioage model demonstrates high correlation with chronological age and other biological ages,and has good predictive performance for mortality outcomes,particularly in middle-aged and elderly populations.

Asthma is a chronic inflammatory disease of the airway involving various cellular players. Among the different phenotypes of asthma, neutrophilic asthma is often associated with severe airway inflammation and a notable resistance to corticosteroid treatment. Macrophages, as innate immune cells, play a crucial role in the pathogenesis of neutrophilic asthma. They regulate neutrophil recruitment and activation to promote the progression of airway inflammation. During this process, macrophages also undergo changes in aspects such as efferocytosis. We reviewed the recent research progresses regarding the role of macrophages in the pathogenesis of neutrophilic asthma, aiming to provide valuable insights for future studies in this area.

Alzheimer's disease (AD) is characterized by cognitive and functional deterioration, with pathological features such as amyloid-beta (Aβ) aggregates in the extracellular spaces of parenchymal neurons and intracellular neurofibrillary tangles formed by the hyperphosphorylation of tau protein. Despite a thorough investigation, current treatments targeting the reduction of Aβ production, promotion of its clearance, and inhibition of tau protein phosphorylation and aggregation have not met clinical expectations, posing a substantial obstacle in the development of drugs for AD. Recently, artificial intelligence (AI), computational biology (CB), and systems biology (SB) have emerged as promising methodologies in AD research. Their capacity to analyze extensive and varied datasets facilitates the identification of intricate patterns, thereby enriching our comprehension of AD pathology. This paper provides a comprehensive examination of the utilization of AI, CB, and SB in the diagnosis of AD, including the use of imaging omics for early detection, drug discovery methods such as lecanemab, and complementary therapies like phototherapy. This review offers novel perspectives and potential avenues for further research in the realm of translational AD studies.
