【Objective】 To perform pre-transfusion examination and major crossmatch test using CD47 anti-idiotypic antibody (CD47 AID) (method 1) and reagent lack of anti-IgG4 anti-human globulin(method 2) in patients treated with CD47 monoclonal antibodies, and evaluate the feasibility of method 1 by comparing the transfusion efficacy of patients after cross matching with two methods. 【Methods】 Post-drug samples were collected from 18 clinical subjects treated with CD47 monoclonal antibody in our hospital. Antibody screening and major crossmatch test were performed using method 1 and method 2, and the difference of ΔHb (post-transfusion Hb minus pre-transfusion Hb) was compared after transfusion. The differences in ΔHb after transfusion were analyzed between the test group using method 1 and the control group without CD47 monoclonal antibody using ordinary microcolumn gel method. 【Results】 There was no significant difference in ΔHb between the test group using method 1 and test group using method 2 (8.40±0.71 vs 7.36±0.94, P>0.05). No significant difference was noticed in ΔHb between the test group using method 1 and the control group without CD47 monoclonal antibody (8.40±0.71 vs 6.59±0.77, P>0.05). 【Conclusion】 In the test group, major crossmatch test with method 1 has the same transfusion efficacy as the test with method 2. Method 1 is simple and easy to operate, and the results are objective and accurate. It is recommended to use method 1 for pre-transfusion antibody screening and major crossmatch tests for patients using CD47 monoclonal antibody.

Objective:To summarize the evidence of cold therapy for patients after knee joint replacement, so as to provide theoretical support for the practical implementation of cold therapy in patients after knee joint replacement in clinical practice.Methods:The literature on cold therapy for patients after knee joint replacement was systematically searched in relevant databases and websites at home and abroad. The search period was from database establishment to September 2022. The evaluation of literature quality and evidence extraction were independently completed by two researchers.Results:A total of 17 articles were included, including two clinical practice guidelines, five systematic reviews, six randomized controlled trials, and four expert consensuses. After independent evaluation and evidence extraction by two researchers, a total of 19 pieces of evidence were collected from 5 aspects: evaluation and education, observation of cold therapy, cold therapy tools, cold therapy parameters, and cold therapy effects. Among them, 8 pieces of A-level recommended evidence and 11 pieces of B-level recommended evidence.Conclusions:Cold therapy for patients after knee joint replacement is widely accepted and applied. Medical and nursing personnel should prioritize patient safety and formulate scientific cold therapy plans based on various factors such as individual differences, patient preferences, actual clinical scenarios, differences in medical equipment, medical and nursing personnel technical level, and cost-effectiveness, in order to maximize patient benefits.

Objective:To observe the effect of Ba Duan Jin(Eight-brocade Exercise)plus Tuina(Chinese therapeutic massage)in treating primary dysmenorrhea due to cold-induced blood stasis in female college students and on the score of fatigue scale-14(FS-14). Methods:Seventy-two female college students with primary dysmenorrhea due to cold-induced blood stasis were randomized into a Tuina group and a joint group,with 36 cases in each group.The Tuina group only received Tuina manipulations.In the joint group,besides the same Tuina manipulations,patients practiced Ba Duan Jin.For both groups,the once-daily intervention was conducted from 6 d before the menstrual period until menstrual day 1 for 3 menstrual cycles.Changes in the scores of COX menstrual symptom scale(CMSS),visual analog scale(VAS),and FS-14 after the intervention were observed.Clinical efficacy was also estimated. Results:During the process,1 case dropped out in the Tuina group,and 35 cases completed the intervention;2 cases dropped out in the joint group,and 34 cases completed the intervention.The total effective rate was 94.1%in the joint group,higher than 88.6%in the Tuina group(P<0.05).After treatment,the symptom duration and intensity scores in the scores of CMSS,VAS,and FS-14 declined in both groups(P<0.05 or P<0.01);the CMSS symptom duration score and FS-14 score were lower in the joint group than in the Tuina group(P<0.05). Conclusion:Tuina manipulations alone or combined with Ba Duan Jin practice can effectively treat primary dysmenorrhea due to cold-induced blood stasis in female college students;when combined with Ba Duan Jin practice,Tuina manipulations can more significantly improve pain duration and fatigue,suggesting the advantages of combining Tuina Gongfa and manipulations.

Axonal degeneration is one of the key features of neurodegenerative disorders. In the canonical view, axonal degeneration destructs neural connections and promotes detrimental disease defects. Here, we assessed the enteric nervous system (ENS) of the mouse, non-human primate, and human by advanced 3D imaging. We observed the profound neurodegeneration of catecholaminergic axons in human colons with ulcerative colitis, and similarly, in mouse colons during acute dextran sulfate sodium-induced colitis. However, we unexpectedly revealed that blockage of such axonal degeneration by the Sarm1 deletion in mice exacerbated the colitis condition. In contrast, pharmacologic ablation or chemogenetic inhibition of catecholaminergic axons suppressed the colon inflammation. We further showed that the catecholaminergic neurotransmitter norepinephrine exerted a pro-inflammatory function by enhancing the expression of IL-17 cytokines. Together, this study demonstrated that Sarm1-mediated neurodegeneration within the ENS mitigated local inflammation of the colon, uncovering a previously-unrecognized beneficial role of axonal degeneration in this disease context.
