Objective:Our aim was to study the relationship between factor v Leiden (FⅤL) mutation and Chinese Budd-Chiari syndrome (BCS). Methods:Twenty-nine BCS patients (25 patients with sporadic BCS,4 with familial BCS ),29 healthy persons were detected for FⅤL mutation with PCR-RFLP.Results: FⅤL mutation was detected in 3 of 4 patients with familial BCS. Two patients in A family and one patient in B family had FⅤL mutation. The mutation was heterozygous. The mutation frequency was 0.0517 in 29 pationts with BCS, 0.3750 in 4 with familial BCS.The frequency of FⅤL mutation in patients and healthy persons showed no statistical difference,but frequency of FⅤL mutation between patients with familial BCS and healthy persons showed significant difference.Conclusion:The FⅤL mutation was related to Chinese familial BCS, but not related to Chinese BCS.

Objective:To systematically evaluate the psychological experience of cancer bereaved, so as to provide basis for bereavement care and intervention.Methods:Qualitative studies on the emotional experiences of cancer bereaved were searched in PubMed, Embase, Cochrane Library, CINAHL, China National Knowledge Infrastructure, WanFang Data, VIP, and China Biomedical Database. The search period was from database establishment to July 2023. The quality evaluation was conducted using the 2020 version of the quality evaluation criteria for qualitative research of the Joanna Briggs Institute Evidence-Based Health Care Center, and the results were integrated using the Meta-synthesis.Results:A total of 11 studies were included, 44 research results were extracted, and 8 new categories and 3 integrated results were summarized, namely the differences in grief emotions after bereavement, grief coping, and support needs after bereavement.Conclusions:The psychological experience of bereaved is relatively complex, and their grief emotions vary. Medical and nursing staff should pay attention to the grief response of the bereaved, guide them to self-adjustment, attach importance to the needs of the bereaved, and provide social support to assist them in returning to society as soon as possible.
