Objective: To investigate the current status of institutional review board construction in blood collection and supply institutions in China, and to provide evidence for standardized management of transfusion medicine ethics. Methods: A questionnaire survey was conducted to assess the development of institutional review boards in blood collection and supply institutions in 31 provinces, municipalities and autonomous regions across the country, excluding hong kong, macao and taiwan. Data were statistically analyzed using the chi-square test and Mann-Whitney U test. Results: Among 83 blood collection and supply institutions, the establishment rate of institutional review boards was 66.27% (55/83), with a higher rate in blood centers than in central blood stations. Of the 55 ethics review committees, 83.64% (46/55) uploaded information and completed registration in the National Medical Research Registration and Filing Information System. The registration rate was higher in blood centers than in central blood stations. On average, each institutional review board conducted 3 initial reviews and approved 2 research projects. The number of initial review items and the number of approved research projects were higher in blood centers than in central blood stations. Common problems in both blood centers and central blood stations included the appointment of the main leader as the director or deputy director, insufficient allocation of ethics professionals, and the general absence of an ethical review system for emergencies. Most committees lacked independent venues, and continuous training coverage was incomplete. Meanwhile, blood collection and supply institutions generally showed high level of ethical recognition of existing blood donation incentive measures. Conclusion: Progress has been made in the construction of transfusion medicine ethics in China; however, shortcomings remain in independence, professional composition of committee members, continuous training, and emergency response systems, requiring targeted improvements.

Sink-associated multidrug-resistant organism(MDRO)infection is primarily caused by multidrug-re-sistant Gram-negative bacilli.The utilization of waterless care can reduce the incidence of such infections and coloni-zation rate,halt outbreaks,and decrease the usage of antimicrobial agents.This paper elucidates the mechanisms of sink-associated MDRO infection,sink configurations and utilization conditions,as well as relevant intervention measures,and expounds the procedures,implementation effect,and implications of waterless care,aiming to pro-vide reference for related research and clinical practice.

The floating thrombus in the brachiocephalic artery is relatively rare and difficult to diagnose,and it is prone to be missed.This article reports a case of a patient with a floating thrombus in the brachiocephalic artery who underwent endovascular treatment via a combined radial artery and femoral artery approach.The patient presented with slurred speech,weakness in the left limbs,and dizziness.A cranial DWI examination revealed acute cerebral infarction in the right cerebral hemisphere and bilateral cerebellum.A neck CTA examination showed a floating thrombus in the brachiocephalic artery.Currently,there is no consensus on the treatment of floating thrombi in the brachiocephalic artery.The effect of conservative medical treatment for this patient was poor,and endovascular treatment was administered.The vertebral artery and carotid artery protection umbrellas were deployed via the radial artery approach to prevent intraoperative embolism events.A stent was deployed via the femoral artery approach to adhere to the thrombus.A follow-up neck CTA examination of the patient after the operation indicated that the stent was in a good position with complete thrombus apposition.

Objective:To investigate the efficacy of blepharoplasty using the "double-line technique" in addressing upper eyelid skin laxity in middle-aged and elderly patients.Methods:A retrospective analysis was conducted on the clinical data of middle-aged and elderly patients with moderate to severe upper eyelid skin laxity who were admitted to the Plastic Surgery Department of Shaanxi Provincial People’s Hospital between January 2020 and January 2023. The same surgeon performed the "double-line" blepharoplasty to excise excess upper eyelid skin for laxity correction. Patients were positioned flat with their eyes closed; an arcuate line a (5-7 mm above the pupil) and a second line b (aligned with the eyelid margin in an upright position) were marked. The skin between these two lines was excised. Postoperatively, the double eyelid shape, improvement in skin laxity, adverse reactions, and patient satisfaction (categorized as satisfied, basically satisfied, unsatisfied) were assessed.Results:A total of 145 patients were included in the study, comprising 27 males and 118 females. Their ages ranged from 38 to 78 years, with an average age of 52 years. All patients’ incisions healed primarily without complications such as hematoma and infection. During the 3 to 12 months of follow-up after surgery, the double eyelid arcs on both sides appeared symmetrical and natural. The upper eyelid laxity was effectively corrected, obscured vision was improved, crow’s feet were reduced, and the periorbital area was rejuvenated. Patient satisfaction with the surgical results was high, with 112 patients reporting satisfaction, 25 reporting basically satisfied, and 8 reporting dissatisfaction. The overall satisfaction rate reached 94.48%(137/145). Among those dissatisfied, 6 cases cited the double eyelid crease as being too narrow, and 2 cases noted asymmetry in the double eyelid crease.Conclusion:The "double-line method" for blepharoplasty is straightforward to perform and effectively removes excess upper eyelid skin. It is suitable for middle-aged and elderly patients with moderate to severe upper eyelid skin laxity, resulting in favorable surgical outcomes.
