OBJECTIVE:
To evaluate the efficacy and safety of DCAG (decitabine, cytarabine, anthracyclines, and granulocyte colony-stimulating factor) regimen in the treatment of patients with relapsed/refractory (R/R) acute myeloid leukemia (AML).
METHODS:
The clinical data of 64 R/R AML patients received treatment at Chinese PLA General Hospital from January 1st, 2012 to December 31st, 2022 were retrospectively analyzed. Primary endpoints included efficacy measured by overall response rate (ORR) and safety. Secondary endpoints included overall survival (OS), event-free survival (EFS) and duration of response (DOR). The patients were followed from enrollment until death, or the end of last follow-up (June 1st, 2023), whichever occurred first.
RESULTS:
Sixty-four patients who failed prior therapy were enrolled and completed 1 cycle, and 26 and 5 patients completed 2 and 3 cycles, respectively. Objective response rate was 67.2% [39: complete remission (CR)/CR with incomplete hematologic recovery (CRi), 4: partial remission (PR)]. With a median follow-up of 62.0 months (1.0-120.9), the median overall survival (OS) was 23.3 and event-free survival was 10.6 months. The median OS was 51.7 months (3.4-100.0) in responders (CR/CRi/PR) while it was 8.4 months (6.1-10.7) in nonresponders ( P <0.001). Grade 3-4 hematologic toxicities were observed in all patients. Four patients died from rapid disease progression within 8 weeks after chemotherapy.
CONCLUSION
The DCAG regimen represents a feasible and effective treatment for R/R AML.

OBJECTIVE:
To analyze the efficacy and safety of decitabine-based myeloablative preconditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with acute myeloid leukemia (AML).
METHODS:
The clinical characteristics and efficacy of 115 AML patients who underwent allo-HSCT at the First Medical Center of Chinese PLA General Hospital from August 2018 to August 2022 were retrospectively analyzed, including 37 patients treated with decitabine conditioning regimen (decitabine group) and 78 patients without decitabine conditioning regimen (non-decitabine group). The cumulative incidence of relapse (CIR), overall survival (OS), leukemia-free survival (LFS), non-relapse mortality (NRM) and graft versus host disease (GVHD) were analyzed.
RESULTS:
For the patients in first complete remission (CR1) state before allo-HSCT, the 1-year relapse rates of decitabine group(22 cases) and non-decitabine group(69 cases) were 9.1% and 29.6%, respectively, the difference was statistically significant(P =0.042). The 1-year cumulative incidence of acute graft-versus-host disease (aGVHD) in decitabine group and non-decitabine group was 62.2% and 70.5%, respectively, and the 1-year cumulative incidence of chronic inhibitor-versus-host disease (cGVHD) was 18.9% and 14.1%, respectively, there were no significant differences in the incidence of aGVHD and cGVHD between the two groups (P >0.05). Of the 115 patients, there were no significantly differences in the 1-year CIR(21.7% vs 28.8%, P =0.866), NRM(10.9% vs 3.9%, P =0.203), OS(75.2% vs 83.8%, P =0.131) and LFS(74.6% vs 69.1%, P =0.912) between the decitabine group(37 cases) and the non-decitabine group(78 cases).
CONCLUSION
Decitabine-based conditioning regimen could reduce the relapse rate of AML CR1 patients with good safety.

Journal of Experimental Hematology 2025;33(4):1069-1078
OBJECTIVE:
To construct the inflammation score (IS) and nutrition-immunity score (NIS) for patients with multiple myeloma (MM), and to verify their prognostic stratification effects and significance.
METHODS:
The clinical data of 129 newly diagnosed MM patients admitted to our hospital from August 2011 to September 2022 were retrospectively analyzed. Univariate and multivariate Cox regression analysis of overall survival (OS) were comducted on clinical parameters, including inflammatory indicators such as red blood cell volume distribution width (RDW) and platelet count (PLT), nutritional-immune indicators such as albumin (ALB), absolute lymphocyte count (ALC), and suppressed immunoglobulin count (S-Ig count). To construct IS and NIS for prognosis, X-tile software and multivariate Cox regression analysis were used to verify the prognostic stratification role and significance of IS and NIS. The time-dependent receiver operating characteristic (ROC) curve, C-index curve, calibration curve, and decision curve analysis (DCA) were used to evaluate the discrimination, accuracy, and clinical net benefit of IS and NIS in predicting overall survival(OS), and compared to the international staging system (ISS).
RESULTS:
IS was constructed based on the scores of RDW and PLT, and NIS was constructed based on the scores of ALB, ALC, and S-Ig count. According to X-tile analysis and multivariate Cox regression analysis, IS and NIS can divide the patients into three risk strata respectively: low, medium and high IS and NIS groups. The differences in OS and hazard ratio (HR) between the low, medium, and high strata were statistically significant (P < 0.05). IS and NIS are both independent prognostic predictors for MM. The area under the ROC curve (AUC) and C index of IS and NIS for predicting 1- to 7-year OS were greater than those of ISS, and both were greater than 0.7. The prediction results of IS and NIS for 1-, 3-, and 5-year OS rates were well consistent with the actual observed results. The DCA curves of IS and NIS for predicting 1-, 3-, and 5-year OS were higher than that of ISS in a wide range of threshold probability intervals.
CONCLUSION
IS and NIS have independent predictive significance for OS in MM patients. Their predictive discrimination, accuracy, and clinical net benefit are higher and better than ISS, and they may have potential application value in MM prognosis.

OBJECTIVE:
The aim of this study is to investigate the main active substances of Qilin pills by high performance liquid chromatogre-electrostatic field orbitrap mass spectrometry (HPLC-Q-Orbitrap /MS), and explore the mechanism of its action in the treatment of asthenozoospermia by combining network pharmacology and molecular docking.
METHODS:
(1) Qilin pills were quantitatively and qualitatively analyzed by HPLC-Q-Orbitrap /MS. (2) The top 100 compounds in Qilin pills were screened by content analysis and SwissADME, and their targets were predicted. The asthenozoospermia targets were searched through the database. And a "protein-protein interaction" (PPI) network was constructed. KEGG and GO analysis was performed using the DAVID database. And a "drug-target-pathway" network was constructed. (3) SailVina was used for molecular docking.
RESULTS:
(1) A total of 1 275 known components were found and ranked in Qilin pills by HPLC-Q-Orbitrap /MS analysis. (2) The top 100 compounds in Qilin pills predicted a total of 1 053 targets and 184 potential therapeutic targets for asthenozoospermia. KEGG pathway analysis and GO analysis showed that the treatment of asthenozoospermia by Qilin pills may be related to the steroid hormone synthesis pathway, the response to steroid hormones, the chromosomal region of cells and the activity of steroid hydroxylase. The mechanism of Qilin pills in treating asthenozoospermia may be related to regulating the synthesis, metabolism and reaction process of sex hormone in the body. (3) The molecular docking results of its key targets (CYP19A1, ESR1, HSP90AA1, p53, HIF1α and BCL2) showed that the key active ingredients M030, M039, M043, M050, M055 and M073 of Qilin pills had spontaneous binding. It had a binding energy of less than -5 kJ /mol.
CONCLUSION
The material basis of Qilin pills has been explored by this study. And the mechanism of action of Qilin pills in the treatment of asthenozoospermia is highly bound to the expression and response process of steroid hormones, which provides a theoretical basis for the clinical application of Qilin pills.

Biomedical and Environmental Sciences 2025;38(3):303-312
OBJECTIVE:
Blood culture remains the gold standard for diagnosing bloodstream infections. Clinical laboratories must ensure the quality of blood culture processes from receipt to obtaining definitive results. We examined laboratory analytical indicators associated with positive blood culture results.
METHODS:
Blood cultures collected from Peking Union Medical College Hospital between January 1, 2020, and December 31, 2022, were retrospectively analyzed. The mode of transportation (piping logistics delivery vs. staff), source of blood cultures (outpatient/emergency department vs. inpatient department), rotation of personnel, and time of reception (8:00-19:59 vs. 20:00-07:59) were compared between blood culture-positive and -negative results.
RESULTS:
Between 2020 and 2022, the total positive rate of blood culture was 8.07%. The positive rate of blood cultures in the outpatient/emergency department was significantly higher than that in the inpatient department (12.46% vs. 5.83%; P < 0.0001). The time-to-detection of blood cultures was significantly affected by the delivery mode and personnel rotation. The blood culture positive rate of the total pre-analytical time within 1 h was significantly higher than that within 1-2 h or > 2 h ( P < 0.0170).
CONCLUSION
Laboratory analytical indicators such as patient source, transportation mode, and personnel rotation significantly impacted the positive detection rate or time of blood culture.

OBJECTIVE:
To identify the key features of facial and tongue images associated with anemia in female populations, establish anemia risk-screening models, and evaluate their performance.
METHODS:
A total of 533 female participants (anemic and healthy) were recruited from Shuguang Hospital. Facial and tongue images were collected using the TFDA-1 tongue and face diagnosis instrument. Color and texture features from various parts of facial and tongue images were extracted using Face Diagnosis Analysis System (FDAS) and Tongue Diagnosis Analysis System version 2.0 (TDAS v2.0). Least Absolute Shrinkage and Selection Operator (LASSO) regression was used for feature selection. Ten machine learning models and one deep learning model (ResNet50V2 + Conv1D) were developed and evaluated.
RESULTS:
Anemic women showed lower a-values, higher L- and b-values across all age groups. Texture features analysis showed that women aged 30-39 with anemia had higher angular second moment (ASM)and lower entropy (ENT) values in facial images, while those aged 40-49 had lower contrast (CON), ENT, and MEAN values in tongue images but higher ASM. Anemic women exhibited age-related trends similar to healthy women, with decreasing L-values and increasing a-, b-, and ASM-values. LASSO identified 19 key features from 62. Among classifiers, the Artificial Neural Network (ANN) model achieved the best performance [area under the curve (AUC): 0.849, accuracy: 0.781]. The ResNet50V2 model achieved comparable results [AUC: 0.846, accuracy: 0.818].
CONCLUSION
Differences in facial and tongue images suggest that color and texture features can serve as potential TCM phenotype and auxiliary diagnostic indicators for female anemia.
