Objective To summarize and analyze the efficacy and influencing factors of second allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acute leukemia relapsing after the first allo-HSCT. Methods Clinical data of 17 patients with acute leukemia who underwent second allo-HSCT at Peking University First Hospital from January 2005 to December 2024 were retrospectively analyzed. Results Among the 17 patients, 7 achieved long-term disease-free survival after second transplantation. The median progression-free survival after successful second transplantation was 7 months (range 8 days to 69 months). The relapse fatality was 24%, and the transplant-related fatality was 35%. Conclusions Second transplantation is an effective treatment for relapsed and refractory acute leukemia, but the relapse fatality and transplant-related fatality remain high. Patient age, time of relapse after the first transplantation and disease status before second transplantation are all factors that affect the efficacy of second transplantation. Younger age, late relapse and complete remission of disease before second transplantation are all beneficial for long-term disease-free survival after second transplantation.

Objective:To investigate the potential characteristic manifestations and application value of the Dynamic Visual Acuity Test（DVAT） in vestibular migraine（VM）. Methods:A total of 50 VM patients（case group） and 50 healthy subjects（control group） diagnosed at the Department of Otorhinolaryngology Head and Neck Surgery, First Hospital of Shanxi Medical University between November 1, 2023, and December 31, 2024, were enrolled. The case group underwent DVAT, video head impulse test（vHIT）, caloric test, and Dizziness Handicap Inventory（DHI） assessment, whereas the control group only received DVAT. Group-based analyses were conducted to examine the effect of age on Dynamic Visual Acuity Loss（DVALoss）, as well as the correlations of DVALoss with vestibular function tests and DHI scores. Results:DVALoss in the case group was significantly higher than that in the control group（P<0.001）. In both groups, age was significantly and positively correlated with DVALoss（P<0.001）. Within the case group, DVALoss was strongly and positively correlated with DHI scores（r=0.807, P<0.001）; it was negatively correlated with the vestibulo-ocular reflex（VOR） gain in vHIT, though without clinical significance, and showed no significant association with the caloric test. Age and DVALoss collectively accounted for 71.3% of the variance in DHI scores（R²=0.713）, with age exerting a relatively minor actual impact. Conclusion:DVAT can sensitively identify the core functional impairments of VM. DVALoss, as a direct functional reflection of the pathological mechanism of VM, is strongly correlated with DHI scores. Incorporating DVALoss into standardized assessments may provide an objective basis for the diagnosis and management of VM.

Objective To explore the efficacy of endoscopic therapy for esophageal and gastric variceal bleeding(EGVB),investigate the risk factors for rebleeding within 1 year,and establish a predictive model accordingly.Methods A retrospective study was conducted using the clinical and follow-up data of 120 EGVB patients who underwent endoscopy at our hospital between January 2021 and December 2022.The efficacy of endoscopic therapy was analyzed,and the patients were divided into a bleeding group and a non-bleeding group based on whether rebleeding occurred within 1 year after treatment.The factors influencing rebleeding within 1 year after treatment were analyzed,and a predictive model was established using logistic regression analysis.The model's goodness of fit was evaluated using the Hosmer-Lemeshow test,and its clinical value was analyzed using the receiver operating characteristic(ROC)curve.Results The hemostasis success rate within 72 hours after endoscopic therapy was 100％in all 120 patients.Four weeks after endoscopic treatment,endoscopic reexamination showed that the complete and partial disappearance rate of varices was 75.83％(91/120),with rebleeding occurring in 10 cases(8.33％).There were 34 cases(28.33％)of cumulative rebleeding at 6 months and 63 cases(52.50％)at 1 year after endoscopic therapy.Nine patients(7.50％)died within 1 year after endoscopic therapy,all of whom were rebleeding cases.A total of 63 patients with rebleeding were included in the bleeding group,and 57 patients without rebleeding were included in the non-bleeding group.Serum sodium＜135 mmol/L(odds ratio[OR]=3.837,95％confidence interval[CI]:1.095-13.445),Child-Pugh grade C(OR=3.835,95％CI:1.137-12.935),esophageal varices degree G3(OR=5.113,95％CI:1.565-16.707),and main portal vein diameter＞12 mm(OR=5.964,95％CI:2.295-15.497)were identified as risk factors of rebleeding within 1 year after endoscopic therapy in EGVB patients(P＜0.05).The risk prediction model for rebleeding within 1 year after endoscopic therapy in EGVB patients was shown as P=1/{1+e[-(-3.815+1.345×serum sodium+1.344×Child-Pugh grade+1.786×main portal vein diameter+1.632×esophageal varices degree)]}.The Hosmer-Lemeshow x2 was 3.158(P=0.856).The area under the curve(AUC)for predicting rebleeding within 1 year after endoscopic therapy in EGVB patients was 0.815,indicating good predictive performance.Clinical validation showed that the model had an accuracy of 82.30％,with sensitivity and specificity being 81.03％and 83.63％,respectively.Conclusion Endoscopic therapy for EGVB achieves a high rate of acute bleeding control,but patients remain at risk of rebleeding.Rebleeding is associated with serum sodium＜135 mmol/L,Child-Pugh grade C,main portal vein diameter＞12 mm,and esophageal varices degree G3.The logistic regression model can effectively predict the probability of rebleeding within 1 year after endoscopic therapy.

Osteoarthritis (OA) causes chronic pain that significantly impairs quality of life, with current treatments often proving insufficient and accompanied by adverse effects. Recent research has identified the dorsal root ganglion (DRG) and its resident macrophages as crucial mediators of chronic OA pain through neuroinflammation driven by macrophage polarization. We present a novel injectable thermo-sensitive hydrogel system, KAF@PLEL, designed to deliver an anti-inflammatory peptide (KAF) specifically to the DRG. This biodegradable hydrogel enables sustained KAF release, promoting the reprogramming of DRG macrophages from pro-inflammatory to anti-inflammatory phenotypes. Through comprehensive in vitro and in vivo studies, we evaluated the hydrogel's biocompatibility, effects on macrophage polarization, and therapeutic efficacy in chronic OA pain management. The system demonstrated significant capabilities in preserving macrophage mitochondrial function, suppressing neuroinflammation, alleviating chronic OA pain, reducing cartilage degradation, and improving motor function in OA rat models. The sustained-release properties of KAF@PLEL enabled prolonged therapeutic effects while minimizing systemic exposure and side effects. These findings suggest that KAF@PLEL represents a promising therapeutic approach for improving outcomes in OA patients through targeted, sustained treatment.

Gene regulation relies on the precise binding of transcription factors (TFs) at regulatory elements, but simultaneously detecting hundreds of TFs on chromatin is challenging. We developed cFOOT-seq, a cytosine deaminase-based TF footprinting assay, for high-resolution, quantitative genome-wide assessment of TF binding in both open and closed chromatin regions, even with small cell numbers. By utilizing the dsDNA deaminase SsdAtox, cFOOT-seq converts accessible cytosines to uracil while preserving genomic integrity, making it compatible with techniques like ATAC-seq for sensitive and cost-effective detection of TF occupancy at the single-molecule and single-cell level. Our approach enables the delineation of TF footprints, quantification of occupancy, and examination of chromatin influences on TF binding. Notably, cFOOT-seq, combined with FootTrack analysis, enables de novo prediction of TF binding sites and tracking of TF occupancy dynamics. We demonstrate its application in capturing cell type-specific TFs, analyzing TF dynamics during reprogramming, and revealing TF dependencies on chromatin remodelers. Overall, cFOOT-seq represents a robust approach for investigating the genome-wide dynamics of TF occupancy and elucidating the cis-regulatory architecture underlying gene regulation.

Objective To evaluate the prognostic value of monocyte human leukocyte antigen-DR(mHLA-DR),neutrophil-to-lymphocyte ratio(NLR),and CD4+T lymphocytes in sepsis.Methods A total of 29 patients with sepsis who were admitted to the department of critical care medicine of Qingdao Municipal Hospital from December 2023 to September 2024 were collected as the study subjects,and the patients were divided into survival group(20 cases)and death group(9 cases)according to the 28-day prognosis.Baseline data were collected from patients at the time of admission[including gender,age,acute physiology and chronic health evaluationⅡ(APACHEⅡ)score,sequential organ failure assessment(SOFA),white blood cell count(WBC),NLR,hemoglobin(Hb),platelet count(PLT),C-reactive protein(CRP),total protein(TP),alanine aminotransferase(ALT),aspartate aminotransferase(AST),creatinine(Cr),CD4+T lymphocyte count]and the mHLA-DR expression rate on the 1st,3rd,and 7th days of admission,and the difference between the mHLA-DR expression rate on the 3rd,7th and 1st days of admission and the 1st day of admission was calculated,which was recorded as ΔH3 and ΔH7.The receiver operator characteristic curve(ROC curve)was used to evaluate the predictive value of mHLA-DR expression,NLR,CD4+T lymphocyte count,SOFA score and APACHEⅡscore on the 28-day mortality risk of sepsis.Results Compared with the survival group,the APACHEⅡscore,SOFA score and NLR in the death group were significantly increased,and the ΔH7 and CD4+T lymphocyte counts were significantly decreased(all P<0.05).ROC curve analysis showed that ΔH7,NLR,CD4+T lymphocyte count,SOFA score and APACHEⅡscore were predictive of the 28-day prognosis of sepsis patients,and area under the curve(AUC)and 95%confidence interval(95%CI)were 0.817(0.635-0.999),0.789(0.611-0.966),0.786(0.588-0.985),and 0.853(0.685-1.000),0.844(0.659-1.000),all P<0.05.The combined detection of ΔH7 combined with NLR,ΔH7 combined with CD4+T lymphocytes,NLR combined with CD4+T lymphocytes,and ΔH7,NLR,and CD4+T lymphocytes also had predictive value for the 28-day prognosis of sepsis patients,with AUC and 95%CI of 0.867(0.735-0.998),0.878(0.752-1.000),0.883(0.760-1.000),and 0.928(0.837-1.000),respectively,all P<0.05.Conclusion The NLR and CD4+T lymphocyte count on the first day of admission to the hospital could predict the prognosis of sepsis patients,and the dynamic monitoring of mHLA-DR expression level in sepsis patients could also predict the prognosis of sepsis patients,but a single measurement of mHLA-DR expression level within 7 days was meaningless.In terms of single indicators,ΔH7 had the best predictor of the prognosis of sepsis patients among the 3 indicators of ΔH7,NLR and CD4+T lymphocyte count,and the combined detection of the 3 indicators was more advantageous in the prognosis of sepsis patients.

Objective:To study the influence of surgical margins on the prognosis of anatomical hepatectomy in patients with hepatocellular carcinoma (HCC) based on a propensity score-matched (PSM) analysis.Methods:Clinical data of 200 patients with HCC undergoing anatomical hepatectomy at the Affiliated Cancer Hospital of Guangxi Medical University from December 2019 to December 2023 were retrospectively analyzed, including 169 males and 31 females, aged 53.4±12.0 years. Patients were divided into the narrow margin group (surgical margin ≤10 mm, n=133) and wide margin group (>10 mm, n=67) according to the width of the surgical margin. PSM was used to compare preoperative indicators such as the maximum diameter of the tumor, the integrity of the tumor capsule, sublesions, and the clinical stage of Barcelona liver cancer (BCLC), perioperative indicators such as intraoperative blood loss, and 24-hour postoperative laboratory indicators such as alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase between the two groups of patients. The prognosis was analyzed by the Kaplan-Meier method, and the postoperative recurrence-free survival rate of the two groups was compared by the log-rank test. Yates corrected chi-square test was used to analyze the postoperative liver function of the two groups of patients. Results:Before PSM, 133 cases were included in the narrow margin group and 67 cases in the wide margin group. There were statistically significant differences in the clinical stage of BCLC, intraoperative blood loss, alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase between the two groups (all P<0.05). After PSM, 55 cases were included in both the narrow margin group and the wide margin group. There were no statistically significant differences in the clinical stage, intraoperative blood loss, alanine aminotransferase and other indicators of BCLC between the two groups (all P>0.05). The 1-year, 2-year, and 3-year recurrence-free survival rates of the wide margin group were 94.2%, 80.1%, and 75.1% respectively, which were higher than those of the narrow margin group (71.8%, 52.9%, and 44.1%), the difference was statistically significant ( χ2=6.25, P=0.012). After PSM, a total of 12 patients (10.9%, 12/110) in the two groups developed liver dysfunction after the operation, among which 10 cases (18.2%, 10/55) were in the wide margin group and 2 cases (3.6%, 2/55). The incidence of postoperative liver dysfunction in the wide margin group was higher than that in the narrow margin group, the difference was statistically significant difference ( χ2=4.58, P=0.032). Conclusion:A surgical margin >10 mm can improve the relapse free survival rate, but it will increase the incidence of postoperative liver dysfunction.
