Objective: To evaluate the practical effectiveness of confidential unit exclusion (CUE) in ensuring blood safety in Zhengzhou, analyze its application characteristics and existing problems, and provide a basis for optimizing blood safety management strategies. Methods: A retrospective analysis was conducted on CUE data handled by Henan Red Cross Blood Center from January 2019 to December 2024. Parameters such as the number of cases, demographic characteristics, reasons for exclusion, and time of report were statistically analyzed and compared with those of non-CUE. Results: From 2019 to 2024, the CUE reporting rate in Zhengzhou was 0.002 6% (40/1 547 666). CUE donors were predominantly male (65.00%, 26/40), aged 18-34 years (47.50%, 19/40), had college degree orabove (50.00%, 20/40), and were employees of enterprises or public institutions (32.50%, 13/40). Among the 40 CUE blood units, only one was reactive for anti-TP, while all others were qualified. The main reasons for CUE were recent vaccination (32.50%, 13/40), medical conditions unsuitable for donation (27.50%, 11/40), and high-risk sexual behavior (17.50%, 7/40). A total of 70.00% of reports occurred within 24 hours after donation, during which none of the corresponding blood units had been released; all units reported after more than 7 days had already been issued for clinical use, with no adverse transfusion reactions reported upon follow-up. Conclusion: The confidential unit exclusion program has played an active role in establishing a supplementary information feedback channel for blood donors. The procedure can be optimized by strengthening interactive communication and confirmation before donation, improving the accuracy of donors' self-assessment, and expanding convenient and rapid information-based reporting channels.

Host-derived small RNAs are emerging as critical regulators in the dynamic interactions between host tissues and the microbiome, with implications for microbial pathogenesis and host defense. Among these, transfer RNA-derived small RNAs (tsRNAs) have garnered attention for their roles in modulating microbial behavior. However, the bacterial factors mediating tsRNA interaction and functionality remain poorly understood. In this study, using RNA affinity pull-down assay in combination with mass spectrometry, we identified a putative membrane-bound protein, annotated as P-type ATPase transporter (PtaT) in Fusobacterium nucleatum (Fn), which binds Fn-targeting tsRNAs in a sequence-specific manner. Through targeted mutagenesis and phenotypic characterization, we showed that in both the Fn type strain and a clinical tumor isolate, deletion of ptaT led to reduced tsRNA intake and enhanced resistance to tsRNA-induced growth inhibition. Global RNA sequencing and label-free Raman spectroscopy revealed the phenotypic differences between Fn wild type and PtaT-deficient mutant, highlighting the functional significance of PtaT in purine and pyrimidine metabolism. Furthermore, AlphaFold 3 prediction provides evidence supporting the specific binding between PtaT and Fn-targeting tsRNA. By uncovering the first RNA-binding protein in Fn implicated in growth modulation through interactions with host-derived small RNAs (sRNAs), our study offers new insights into sRNA-mediated host-pathogen interplay within the context of microbiome-host interactions.

Objective:To evaluate cerebrospinal fluid (CSF) flow dynamics and volume changes of pulsatile tinnitus (PT) patients induced by sigmoid sinus wall dehiscence (SSWD) using MRI.Methods:This was a cross-sectional study. Totally 55 SSWD-PT patients, and 35 age- and sex-matched healthy controls were prospectively enrolled at Beijing Tongren Hospital, Capital Medical University from October 2019 to September 2023. The CSF at the midbrain aqueduct level was analyzed based on phase-contrast MRI to obtain the flow dynamics information. Based on T 1-weighted turbo field echo sequence, the CSF was segmented and the volume of CSF was calculated using ITK-SNAP software. The Mann-Whitney U test was used to compare the differences of each parameter between the two groups. Binary logistic regression was used to analyze the parameters with statistically significant differences to obtain the independent influencing factors of SSWD-PT and establish the combined parameters. Receiver operating characteristic curve analysis was used to evaluate the efficacy of diagnosing SSWD-PT. Results:Compared with controls, the SSWD-PT group showed significantly decreased mean flux (MF), mean velocity, peak velocity( P<0.05), and significantly increased regurgitant fraction (RF), CSF volume ( P<0.05). No significant differences were observed in forward flow volume, backward flow volume, and stroke volume ( P>0.05). The logistic regression results showed that MF ( OR=0.497, 95% CI 0.305-0.808, P=0.005) and RF ( OR=1.809, 95% CI 1.040-3.147, P=0.036) were independent influencing factors of SSWD-PT. The area under the curve (AUC) of MF and RF for diagnosing SSWD-PT were 0.641 (95% CI 0.517-0.766) and 0.675 (95% CI 0.564-0.786), respectively. The AUC of the combination of MF and RF was 0.724 (95% CI 0.614-0.833). Conclusions:SSWD-PT patients have abnormal changes in CSF flow dynamics and volume. The MF and RF demonstrate moderate diagnostic value for diagnosing SSWD-PT.

Objective To construct a patient decision aid(PtDA)for exercise training in pa-tients with chronic obstructive pulmonary disease(COPD)and explore its impacts on decision-making quality of patients' exercise regimens.Methods The development of the PtDA for exercise training in COPD patients was accomplished through literature analysis,the Delphi method,and user surveys,followed by an intervention study.A total of 59 inpatients with COPD were included as study sub-jects.The control group received routine care along with general exercise training guidance,while the intervention group received routine care combined with shared decision-making for exercise training based on the PtDA.The decision conflict and decision preparedness levels of patients in both groups were compared before the intervention and on the day of discharge.The exercise self-efficacy of pa-tients was measured before intervention,on the day of discharge,and 1 month and 3 months after dis-charge.Results The intervention group had significantly lower scores for decision conflict and signif-icantly higher scores for decision preparedness and exercise self-efficacy compared with the control group(P＜0.05).Conclusion The PtDA for exercise training can improve decision conflict and de-cision preparedness in COPD patients,enhance their exercise self-efficacy levels,and provide references for healthcare professionals in improving exercise adherence.

Objective To prepare washed platelets by automatic blood cell treatment system ACP215 and evaluate the in vitro quality of the platelets after washing.Methods Based on the ACP215 washing program,the improved disposable consum-ables,as well as the prepared platelet washing solution and suspension,were applied to automatically wash and prepare single bags of platelets.The platelet volume,platelet content,plasma protein content,PDW,MPV and PH before and after washing were compared,and compared with the traditional manual washing method.After storage for 24 hours,platelet aggregation test,thromboelastography MA evaluation and subcellular structure photoimaging were performed.Results The recovery rate was(87.55±2.54)％and plasma protein clearance was(95.84±0.69)％,which were significantly higher than the conventional manual method(Z=-13.633,P＜0.01;Z=-12.039,P＜0.01).There was no statistical difference in maximum aggregation and aggregation time of platelets before and after washing(t=1.273,P=0.218;t=0.770,P=0.451).MA value was slightly reduced(t=2.236,P=0.038).There was no statistical difference in subcellular structure before and after washing(x2=2.257,P=0.133;x2=0.523,P=0.469).Conclusion Utilization of automatic blood cell treatment system ACP215 can standardize and automatically prepare washing platelets which meet the quality requirements.The platelets has good in vitro function after washing and 24 hours of storage.

The lack of preoperative guidelines for the management of drugs for psychiatric disorders will affect the quality of surgical management of psychiatric patients and increase the probability of perioperative complications.To standardize the preoperative management of medications for the treatment of mental disorders,the Perioperative Assessment and Quality Improvement Society issued《Preoperative Management of Medications for Psychiatric Diseases:Society for Perioperative Assessment and Quality Improvement Consensus Statement》in February 2022 to provide clinicians with recommendations for the preoperative management of psychotropic medications.This article interpreted the consensus,summarized the perioperative interactions,special precautions,and auxiliary examination precautions,and provided corresponding preoperative suggestions on antidepressants,mood stabilizers,anxiety,antipsychotics,and attention deficit hyperactivity disorder drugs,to provide a reference for the standardized management of perioperative drugs.

Tumor necrosis factor alpha inhibitors(TNFαi)are a class of biological agents that suppress the immune system and lower inflammatory levels,and they are increasingly employed to treat autoimmune diseases.However,TNFαi theoretically can increase the risk of infection,tumor,and other complications.To increase the safety of perioperative medicine,it is necessary to balance the relative risks of increased complication rates due to continuous medication and symptom aggravation due to medication suspension for patients undergoing surgery.Currently,there is no comprehensive clinical guideline for the perioperative management of TNFαi in China.To provide a reference for the perioperative management of TNFαi,this article used the indications of rheumatoid arthritis,ankylosing spondylitis,inflammatory bowel disease,and psoriasis as its starting point to systematically sort out the recommendations and considerations for the use of TNFαi in the perioperative drug treatment of patients.
