Objective: To analyze the demographic evolution of China over the forthcoming decade (2026-2035) and to systematically evaluate its potential implications for voluntary blood donation practices and the equilibrium of clinical blood supply and demand. Methods: Leveraging comprehensive blood collection and utilization data from 2021 to 2025 at the national, provincial (Shandong), and municipal (Zibo) levels, we identified and examined critical determinants influencing blood management systems. The DeepSeek-V3.2 large language model was deployed to project future population age structures, and to generate quantitative estimates for hospitalization volumes, clinical blood requirements, available blood supply, and donation frequencies for the target years 2030 and 2035, thereby furnishing an evidence base for strategic planning and priority-setting. Results: DeepSeek-derived projections indicate that the proportion of China's population aged 60 years and above will surpass 27% (370 million/1 380 million) by 2030 and exceed 30% (400 million/1 350 million) by 2035, signaling a marked acceleration in population aging. This demographic shift is projected to reduce the proportion of the national population eligible to donate blood from 59.2% (835 million out of 1.41 billion) to 52% (710 million out of 1.36 billion), while the demand for blood is expected to increase by 87.8% relative to 2024, rising from 26.927 million units to 50.56 million units. Sustaining blood supply-demand balance will necessitate progressive annual increases in donation rates. Under prevailing policy frameworks, the required blood donation rate among the eligible population in Shandong Province would need to rise by 122.57% by 2035 [from 20.07‰ (1.1641 million person-times/58 million people) to 44.67‰ (2.189 million person-times/49 million people)] to potentially satisfy projected clinical requirements. Conclusion: By integrating DeepSeek-V3.2, AI predictive models, and blood donation incentive measures, it is possible to monitor population demographics, forecast clinical blood demand, manage blood supplies, and ensure the long-term sustainability of clinical blood availability. It must be acknowledged, however, that the present analysis is constrained by a limited data foundation (comprising only five annual observation points); accordingly, the projections should be interpreted as directional trend indicators or methodological illustrations rather than definitive quantitative forecasts.

ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

SHCBP1 is a type of Src homologous collagen that can specifically bind to the SH2 structural domain. It can act as a key regulatory protein, and exhibits abnormally high expression in a variety of malignant tumors. Through affecting the processes such as cell cycle, proliferation, and invasion, it participates in tumor genesis and development. In addition, high expression of SHCBP1 is closely related to chemotherapy resistance and poor prognosis of many malignant tumors, and its targeted inhibition can enhance the sensitivity of chemotherapy and provide new therapeutic strategies for a variety of solid tumors, making it an important biomarker for prognostic assessment and a potential therapeutic target.

Objective To investigate the predictive value of B-type natriuretic peptide(BNP)for acute exacerbation of chronic obstructive pulmonary disease(AECOPD)complicated by right heart failure(RHF).Methods This study selected AECOPD patients admitted to Jiangyin Hospital Affiliated to Nantong University and Nanjing Chest Hospital from January 2022 to January 2024 as ob-jects.According to the inclusion and exclusion criteria,122 patients were ultimately enrolled.The patients were divided into observation group(AECOPD with RHF,n=72)and control group(AECOPD without RHF,n=50)based on whether they had RHF.Differences in various indicators between the two groups were compared,and the predictive value of BNP for AECOPD patients with RHF was assessed through Logistic regression analysis and receiver operating characteristic(ROC)curves.The cut-off value of BNP was determined using the ROC curve.Results Statistically signifi-cant differences were observed between the two groups in terms of gender,body temperature,albumin,blood glucose,chloride ions,pulmonary artery pressure(PAP),and BNP levels(P＜0.05).Logistic regression analysis showed that BNP was an independent predictor for AECOPD patients with RHF(OR=1.03;95％CI,1.01 to 1.04;P＜0.05).The ROC curve results indicated that when the BNP cut-off value was 83.5 pg/mL,the sensitivity was 0.820,the specificity was 0.972,and the Youden index was 0.792.The area under the curve for BNP was 0.875(95％CI,0.800 to 0.949,P＜0.001).When the BNP level in AECOPD patients exceeded 83.5 pg/mL,the incidence of RHF significantly increased.Conclusion Patients with AECOPD complicated by RHF have higher plasma BNP levels than those without RHF,and BNP has significant predictive value for determining whether AECOPD patients have RHF.

Objective:To investigate the application effect of a rehabilitation diary combined with self-identity psychological nursing in adolescent patients with major depressive disorder (MDD), and to provide a reference for optimizing intervention strategies for adolescent MDD.Methods:A prospective randomized controlled trial was conducted. A total of 110 adolescent patients with MDD admitted to Zhejiang Provincial People's Hospital from July 1, 2024, to January 31, 2025 were selected as research subjects by continuous sampling method. Fifty-five patients who received routine nursing care from July 1, 2024, to September 30, 2024, were assigned to the control group. Fifty-five patients who received a rehabilitation diary combined with self-identity psychological nursing from October 1, 2024, to January 31, 2025, were assigned to the combined group. The improvement status of MDD symptoms (Montgomery-Asberg Depression Rating Scale), interpersonal relationship (Interpersonal Relationship Assessment Scale), social function (Social Disability Screening Schedule), et al, were compared between groups.Results:A total of 110 patients were included. In the control group, there were 29 males and 26 females, aged (15.38 ± 1.35) years old. In the combined group, there were 28 males and 27 females, aged (15.17 ± 1.36) years old. Before the intervention, there were no statistically significant differences in the improvement of MDD symptoms, interpersonal relationships, and social functions between the two groups of patients (all P>0.05). After 4 and 8 weeks of intervention, the scores of the Montgomery-Asberg Depression Rating Scale and the Social Disability Screening Schedule in the combined group were 25.47 ± 4.12, 22.35 ± 4.29, 12.41 ± 1.68, 11.02 ± 1.32, respectively, which were lower than those of the control group 30.16 ± 5.32, 27.29 ± 4.61, 14.18 ± 1.32, 12.45 ± 2.27, the differences were statistically significant ( t values were 4.04-6.49, all P<0.05). After 8 weeks of intervention, the scores of interpersonal communication, interpersonal friendship, dealing with people and matters, opposite-sex interaction of the Interpersonal Relationship Assessment Scale in the combined group were 4.62 ± 0.53, 4.28 ± 0.38, 4.35 ± 0.61, 3.97 ± 0.28 respectively, which were lower than those of the control group 5.37 ± 0.41, 5.32 ± 0.79, 5.28 ± 0.53, 4.86 ± 0.64, and the differences were statistically significant ( t values were 8.30-9.45, all P<0.05). Conclusions:Rehabilitation diary combined with self-identity psychological nursing intervention for adolescent MDD patients can improve the depression symptoms, interpersonal relationship and social function, and enhance the treatment compliance and quality of life.

Objective:To compare the clinical and laboratory characteristics and survival between Chinese and Western patients with myelodysplastic neoplasms (MDS) .Methods:Clinical and laboratory data were collected from 1,464 primary adult patients diagnosed with MDS at the Institute of Hematology & Blood Diseases Hospital from August 2016 to June 2024. Collected data were retrospectively analyzed and compared with 2,191 patients from the International Working Group for the Prognosis of Myelodysplastic Syndromes (IWG-PM) .Results:Chinese patients were significantly younger (median age: 56 years vs. 72 years, P<0.001) and experienced more severe hematopenia ( P<0.001) compared with patients from the IWG-PM. Further, Chinese patients exhibited a higher percentage of isolated del (20q), +8, and complex karyotypes as well as a lower percentage of normal karyotypes, del (5q), and -Y ( P<0.001). Higher U2AF1, NRAS, and NPM1 mutation rates and lower ASXL1, SF3B1, and RUNX1 mutation rates were observed in Chinese patients than in participants from the IWG-PM ( P<0.05). No significant difference in overall survival (OS) was found between the two groups (median OS: 48 [95% CI: 40 - 56]months, vs. 45[95% CI: 40 - 49] months; P=0.449). Among participants aged ≤45 years, Chinese patients demonstrated more trisomy 8 ( P=0.070) and U2AF1 mutation ( P<0.001) and higher 4-year OS rate compared with those from the IWG-PM (75.5% vs. 62.1%, P=0.001). Among participants aged ≥70 years, Chinese patients exhibited more complex karyotypes but fewer del (5q) as well as more NPM1 but less SF3B1 and TET2 compared with those from the IWG-PM ( P<0.05). Chinese patients demonstrated shorter survival (median OS: 20 [95% CI: 13 - 27] months vs. 37 [95% CI: 32 - 42] months, P<0.001) . Conclusion:Chinese and Western MDS patients differ in age of onset, clinical features, and cytogenetic or molecular genetic abnormalities, with significant differences persisting in age-matched groups. Although the OS is similar, disparities exist in survival for younger and older patients between the two populations.

Objective:To identify the prognostic value of the Revised 15-item Myelodysplastic Syndrome-specific frailty scale (FS-15) in Chinese patients with myelodysplastic syndromes (MDS) .Methods:This retrospective study analyzed 812 patients with newly diagnosed MDS admitted to the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences, and Peking Union Medical College from August 2016 to June 2023. Patients were assessed using the FS-15 and subsequently categorized into frail and non-frail groups. Clinical and laboratory characteristics, as well as overall survival (OS), were compared between these groups.Results:① The median patient age was 55 years ( IQR 45–64), with a median follow-up of 22.5 months (95% CI: 20.2–24.9) and a median OS of 43.3 months (95% CI: 36.8–49.8). The median FS-15 score was 0.42, with a cutoff value of 0.44. Male patients demonstrated higher median FS-15 scores than female patients (0.42 vs 0.38, P=0.006). In both the Revised International Prognostic Scoring System (IPSS-R; P=0.001) and Molecular International Prognostic Scoring System (IPSS-M; P=0.014) stratifications, FS-15 scores were significantly higher in the very high-risk group compared with the very low-risk group. ② The median OS was 54.7 months (95% CI: 47.5–NA) and 31.5 months (95% CI: 22.9–41.0) in the nonfrail ( n=452) and frail groups ( n=360), respectively ( P<0.001). The 3-year OS rates were (63.2 ± 3.2) % and (46.4 ± 3.6) % for the non-frail and frail groups, with 5-year OS rates of (49.9 ± 4.7) % and (32.0 ± 4.3) %, respectively ( P<0.001). ③Subgroup analysis revealed that nonfrail patients demonstrated significantly higher 3-year OS rates than frail patients in both the IPSS-M low-risk and very high-risk groups (all P<0.05). Similarly, nonfrail patients demonstrated superior 3-year OS rates compared with frail patients in the IPSS-R very low-risk, low-risk, and high-risk groups (all P<0.05). ④Among patients receiving hypomethylating agent therapy, the overall response rate was significantly higher in the non-frail group than in the frail group (86.7% vs 64.6%, P=0.007). Moreover, the frail group experienced higher rates of treatment-related adverse events, including febrile neutropenia (67.1% vs 47.4%, P=0.016) and liver function abnormalities (30.0% vs 14.5%, P=0.023), compared with the non-frail group. Conclusion:The FS-15 frailty score is a feasible and effective tool for assessing frailty in patients newly diagnosed with MDS in China and serves as a valuable prognostic indicator.

Objective:To investigate the clinical, laboratory, and prognostic features of myelodysplastic neoplasm (MDS) patients harboring acute myeloid leukemia (AML) -like mutations.Methods:We retrospectively analyzed clinical, molecular, and outcome data from 1 464 adults with primary MDS diagnosed at the Institute of Hematology and Blood Diseases Hospital from August 2016 to June 2024.Results:AML-like mutations were detected in 64 patients (4.4% ). Compared with patients without AML-like mutations, those with AML-like mutations were younger [median 50 ( IQR 39–60) vs 56 (45, 65) years; P=0.001], more often female (51.6% vs 35.4% ; P=0.009), had higher bone marrow blast percentage [6.5% (3.0%, 10.5% ) vs 2.5% (1.0%, 7.0% ) ; P<0.001], a higher rate of normal karyotype (75.0% vs 48.1% ; P<0.001), and lower hemoglobin levels [73 (67, 82) g/L vs 80 (66, 98) g/L; P=0.006]. The AML-like group had a higher number of gene mutations than the non-AML-like group [3 ( IQR 2–4) vs 2 (1, 3) ; P<0.001). It was enriched for mutations in NPM1, DNMT3A, WT1, PTPN11, NRAS, BCOR, FLT3, CEBPA, and MYC (all P<0.05) and had lower rates of U2AF1, ASXL1, and TP53 mutations (all P<0.05). Overall survival (OS) did not differ between groups ( P=0.730) ; however, the AML-like group had significantly shorter leukemia-free survival (LFS) [19 months (95% CI: 13–25) vs 46 months (95% CI: 38–54) ; P=0.012] and a higher 2-year cumulative incidence of AML transformation [ (41.7±9.1) % vs (10.4±1.1) % ; P<0.001]. Within the AML-like group, OS, LFS, and cumulative incidence of AML transformation did not differ between patients with low blasts and those with excess blasts (IB). Multivariable Cox regression identified age ≥60 years and PTPN11 mutations as independent adverse prognostic factors for OS, while DNMT3A, PTPN11, and FLT3 mutations independently predicted leukemic transformation. Conclusions:MDS patients harboring AML-like mutations exhibit distinct clinical and molecular features and a higher risk of progression to AML.

Objective:To explore the risk fall death associated with compound hot extremes.Methods:This study collected data on fall deaths in Guangdong, Hunan, and Zhejiang Provinces from 2013 to 2018 and matched their exposure to meteorological data. Based on a time-stratified case-crossover design, a conditional logistic regression model embedded with a cross-basis function of the distributed lag nonlinear model was applied to estimate the risk of fall to death due to compound hot extremes.Results:Compared with regular days, compound hot extremes significantly increased the risk of death from falls ( OR=1.19, 95% CI: 1.09-1.30), and women ( OR=1.27, 95% CI: 1.11-1.45) and the elderly age 65 and above ( OR=1.24, 95% CI: 1.12-1.39) were more sensitive to compound hot extremes. The maximum duration of compound hot extremes was 7 days, and the maximum intensity was 6.2 ℃, and the duration and intensity were proportional to the risk of death from falls. The risk of death from falls increased by 12% ( OR=1.12, 95% CI: 1.06-1.18) each day, increasing in duration after linearization. The risk of death from falls increased by 16% ( OR=1.16, 95% CI: 1.10-1.22) for each 1 ℃ increase in linearized intensity. Conclusion:Compound hot extremes increase the risk of death cases from falls.
