Objective To analyze the clinical manifestations of delayed serological transfusion reactions(DSTR)after platelet transfusion in tumor patients,and to explore the transfusion strategy.Methods Clinical data and laboratory test re-sults of patients with positive antibody screening were analyzed after platelet transfusion in our hospital from January 1,2015 to June 30,2023,and the incidence rate,clinical characteristics and transfusion strategy of patients with DSTR were ana-lyzed.Results A total of 2 553 patients with 6 057 platelet transfusions were reviewed.Eight patients developed DSTR and received a total of 21 therapeutic amounts of platelets,and 5 patients were subsequently transfused with red blood cells.Rh system antibodies were detected in 7 cases(4 anti-E,1 anti-c/E,1 anti-C and 1 anti-c)and Kell system antibodies in 1 case.Conclusion Tumor patients may also develop DSTR after platelet transfusion.It is necessary to pay close attention to the antibody situation and perform matched transfusion when transfusing blood again.

Objective:To compare the clinical efficacy of neoadjuvant chemoradiotherapy (nCRT) and neoadjuvant chemo-immunotherapy (nCIT) for locally advanced esophageal squamous cell carcinoma (ESCC).Methods:Clinical data of patients who received nCRT or nCIT followed by esophagectomy for locally advanced ESCC between January 2010 and December 2022 were retrospectively collected from Zhejiang Cancer Hospital, with 155 patients in the nCRT group and 470 patients in the nCIT group. Propensity score matching (PSM) was performed in the two groups. After PSM, 120 patients were allocated to the nCRT group and 192 patients to the nCIT group. The pathological response and disease recurrence were compared between the two groups after PSM. Log rank test were used to compare the survival outcomes before and after PSM. Univariate and multivariate Cox regression analyses were performed to identify the prognostic factors for locally advanced ESCC.Results:After PSM, the R0 resection rate in the nCRT group and the nCIT group was 93.3% (112/120) and 93.8% (180/192), respectively, with no statistical significance ( P=0.884). However, the pathological complete response rate in the nCRT group [36.7% (44/120)] was higher than that in the nCIT group [21.4% (41/192), P=0.003]. For patients with R0 resection, the major recurrence pattern was distant metastasis [18.8% (21/112)] in the nCRT group, while the pattern was locoregional recurrence [12.2% (22/180)] in the nCIT group. The 3-year disease-free survival rates were 52.7% and 66.1% ( P=0.022) and the 3-year overall survival rates were 59.2% and 75.5% ( P=0.002) in the nCRT and nCIT groups, respectively. Multivariate Cox regression analysis also revealed that the neoadjuvant therapy mode was an independent prognostic factor for patients with locally advanced ESCC. Compared with nCRT, nCIT could significantly prolong disease-free survival ( HR=0.58, 95% CI: 0.40-0.86) and overall survival ( HR=0.53, 95% CI: 0.35-0.79). Conclusion:These results suggest that nCIT could significantly improve disease-free survival rate and overall survival rate over nCRT in locally advanced ESCC, even with lower pathological complete response rate.

Heart failure(HF)is the end stage of almost all cardiovascular diseases,including coronary heart disease and structural heart disease.For end-stage HF,medications and cardiac assist devices have limited therapeutic effects,and heart transplantation is associated with donor shortage and immune rejection.Alginate hydrogel has the ability to mechanically support and induce cardiac tissue regeneration and repair.In March 2021,we conducted the world's first transcatheter endocardial alginate-hydrogel implantation in patients with end-stage heart failure,and explored the safety and feasibility of the treatment.Given that patients with heart failure who had undergone cardiac resynchronization therapy defibrillator(CRT-D)were excluded from previous studies,this paper is the first to report a case of transcatheter endocardial alginate-hydrogel implantation in a patient with heart failure who did not respond to CRT-D,with a significant reduction in the number of visits to the doctor and a significant improvement in the quality of life during the post-procedure follow-up,which may expand the indications for the use of this technology.

Objective:To analyze the dose-response relationship of 99Tc m-dimercaptosuccinic acid (DMSA) in pediatric renal static imaging. Methods:A retrospective analysis of children (model group: n=199, 81 males, 118 females; validation group: n=30, 13 males, 17 females; all age: 1 month-14 years) who underwent 99Tc m-DMSA renal static imaging from January 2022 to November 2023 in Wuhan Children′s Hospital, Tongji Medical College, Huazhong University of Science and Technology were conducted. Post-administration radiation counts and related clinical data were collected. Imaging quality was evaluated using visual analogue scoring (VAS). ROC curve analysis was used to assess the relationship between radiation count intensity (RCI) and imaging quality. A nonlinear mixed-effects modeling method was employed to establish the dose-response relationship for 99Tc m-DMSA in pediatric renal static imaging. Internal and external validations of the model were performed. Final model was utilized to evaluate patient dosing protocols. Results:Body weight was considered as a significant determinant of the dose-response relationship in 99Tc m-DMSA renal static imaging( χ2 values: 120.79, 116.36, both P<0.05). ROC curve analysis showed that the quality of diagnostic images was acceptable when the anterior renal RCI was ≥32.61 (cut-point) and the posterior renal RCI was ≥35.46 (cut-point). Both internal and external validation results demonstrated that the dose-response model established exhibited good prediction performance. Based on the final model graph, the image quality could meet the requirements for clinical diagnosis. Conclusions:The 99Tc m-DMSA dose-response model for pediatric renal static imaging is successfully established. Individualized dosage based on the model can provide a reference for clinical individualized dosing decision-making.

OBJECTIVE: To compare the clinical efficacy of acupuncture, Chinese medication and combination of acupuncture and medication in the treatment of dry eye complicated with computer vision syndrome (CVS). METHODS: A total of 152 patients with dry eye complicated with CVS were randomly divided into an acupuncture-medication group (38 cases, 1 case was removed), an acupuncture group (38 cases, 1 case dropped off), a Chinese medication group (38 cases, 1 case was removed), and a western medication group (38 cases, 1 case dropped off). In the western medication group, sodium hyaluronate eye drop combined with esculin and digitalis glycosides eye drop were used. In the acupuncture group, acupuncture was applied at bilateral Taiyang (EX-HN 5)， Cuanzhu (BL 2), Fengchi (GB 20), Qimen (LR 14) , and Hegu (LI 4) etc., once a day. In the Chinese medication group, Yiqi Congming decoction formula ganule was given orally, one dose a day. In the acupuncture-medication group, acupuncture combined with Yiqi Congming decoction formula granule were used. All groups were treated for 14 d. The non-invasive first tear film break-up time (NIBUT f), non-invasive average tear film break-up time (NIBUT av), tear meniscus height (TMH), ocular surface disease index (OSDI) score, and CVS symptom score were compared between the patients of each group before and after treatment. RESULTS: After treatment, the NIBUT f, NIBUT av, and TMH were increased compared with those before treatment in the patients of the 4 groups (P<0.01); the NIBUT f and NIBUT av in the acupuncture-medication group and the acupuncture group were higher than those in the Chinese medication group and the western medication group (P<0.05), and the TMH in the acupuncture-medication group and the Chinese medication group were higher than those in the acupuncture group and the western medication group (P<0.05). After treatment, the OSDI scores, the various scores and total scores of CVS (except for head symptom score in the western medication group) were decreased compared with those before treatment in the patients of the 4 groups (P<0.01). The OSDI score, total score, eye symptom score, and body symptom score of CVS in the acupuncture-medication group were lower than those in the acupuncture group, the Chinese medication group, and the western medication group (P<0.01, P<0.05), the head symptom score of the acupuncture-medication group was lower than that in the western medication group (P<0.05), and the CVS physical symptom scores and mental cognitive symptom scores of the acupuncture-medication group and the acupuncture group were lower than those in the Chinese medication group and the western medication group (P<0.05). CONCLUSION Acupuncture has advantages in improving NIBUT f, NIBUT av, and CVS physical symptoms and cognitive symptoms, and the Chinese medication has advantage in improving TMH. The combination of acupuncture and Chinese medication has better effects compared with monotherapy.

Objectives: To investigated the safety and efficacy of treating patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) and elevated levels of N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) with levosimendan within 24 hours of first medical contact (FMC). Methods: This multicenter, open-label, block-randomized controlled trial (NCT03189901) investigated the safety and efficacy of levosimendan as an early management strategy of acute heart failure (EMS-AHF) for patients with NSTEMI and high NT-proBNP levels. This study included 255 patients with NSTEMI and elevated NT-proBNP levels, including 142 males and 113 females with a median age of 65 (58-70) years, and were admitted in the emergency or outpatient departments at 14 medical centers in China between October 2017 and October 2021. The patients were randomly divided into a levosimendan group (n=129) and a control group (n=126). The primary outcome measure was NT-proBNP levels on day 3 of treatment and changes in the NT-proBNP levels from baseline on day 5 after randomization. The secondary outcome measures included the proportion of patients with more than 30% reduction in NT-proBNP levels from baseline, major adverse cardiovascular events (MACE) during hospitalization and at 6 months after hospitalization, safety during the treatment, and health economics indices. The measurement data parameters between groups were compared using the t-test or the non-parametric test. The count data parameters were compared between groups using the χ² test. Results: On day 3, the NT-proBNP levels in the levosimendan group were lower than the control group but were statistically insignificant [866 (455, 1 960) vs. 1 118 (459, 2 417) ng/L, Z=-1.25,P=0.21]. However, on day 5, changes in the NT-proBNP levels from baseline in the levosimendan group were significantly higher than the control group [67.6% (33.8%,82.5%)vs.54.8% (7.3%,77.9%), Z=-2.14, P=0.03]. There were no significant differences in the proportion of patients with more than 30% reduction in the NT-proBNP levels on day 5 between the levosimendan and the control groups [77.5% (100/129) vs. 69.0% (87/126), χ²=2.34, P=0.13]. Furthermore, incidences of MACE did not show any significant differences between the two groups during hospitalization [4.7% (6/129) vs. 7.1% (9/126), χ²=0.72, P=0.40] and at 6 months [14.7% (19/129) vs. 12.7% (16/126), χ²=0.22, P=0.64]. Four cardiac deaths were reported in the control group during hospitalization [0 (0/129) vs. 3.2% (4/126), P=0.06]. However, 6-month survival rates were comparable between the two groups (log-rank test, P=0.18). Moreover, adverse events or serious adverse events such as shock, ventricular fibrillation, and ventricular tachycardia were not reported in both the groups during levosimendan treatment (days 0-1). The total cost of hospitalization [34 591.00(15 527.46,59 324.80) vs. 37 144.65(16 066.90,63 919.00)yuan, Z=-0.26, P=0.80] and the total length of hospitalization [9 (8, 12) vs. 10 (7, 13) days, Z=0.72, P=0.72] were lower for patients in the levosimendan group compared to those in the control group, but did not show statistically significant differences. Conclusions: Early administration of levosimendan reduced NT-proBNP levels in NSTEMI patients with elevated NT-proBNP and did not increase the total cost and length of hospitalization, but did not significantly improve MACE during hospitalization or at 6 months.

OBJECTIVE: To analyze factors associated with intestinal acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation(allo-HSCT) in children and to develop a prediction model for intestinal aGVHD after allo-HSCT in children. METHODS: The clinical data of 62 children who underwent allo-HSCT at the Department of Hematology of the People's Hospital of Xinjiang Uygur Autonomous Region from February 2018 to September 2021 were retrospectively analyzed. Intestinal aGVHD was evaluated according to the Mount Sinai Acute GVHD International Consortium (MAGIC) grading criteria, the variables were screened by LASSO (least absolute shrinkage and selection operator) regression analysis with 10-fold cross-validation, and developed a model for predicting intestinal aGVHD after allo-HSCT in children. RESULTS: A total of 33 (53.2%) of the 62 children developed intestinal aGVHD, of which 25 were degree II and 8 were degree III-IV. The results of screening variables by 10-fold cross-validated LASSO regression showed that the significant variables included ethnic minorities (OR =7.229; 95%CI: 2.337-22.354), platelet (PLT) (OR =0.971; 95%CI: 0.932-0.993), uric acid (UA) (OR =0.971; 95%CI: 0.935-0.988), C-reactive protein (CRP) (OR =1.217; 95%CI: 1.053-1.545), and viral infection (OR =10; 95%CI: 3.021-32.668), and these variables were independently associated with intestinal aGVHD in children (all P <0.05). A prediction model was constructed based on above variables. The area under the receiver operating characteristic (ROC) curve (AUC) of the model was calculated, and the AUC value was 0.985 (0.966-1), the Brier score was 0.055. The evaluation showed that the model has a high degree of discrimination and calibration. CONCLUSION Ethnic minorities, low PLT, low UA, high CRP, and viral infections are independently associated with intestinal aGVHD in children, and early attention should be paid to these high-risk children.
