Objective: To analyze the changes in homologous immunity after RhCE-matched transfusion in positive patients with RhCE blood group antibodies, and to provide precise transfusion strategies for chronic anemia patients. Methods: Patients with chronic anemia in our hospital from January 2020 to March 2024 (continuously receiving blood transfusions for more than 6 months) were enrolled, and 63 cases of unexpected antibody screening positive and identified as RhCE blood group antibodies were selected as the research subjects. The changes in unexpected antibody yield rate after ABO and RhCcDEe isotype blood transfusion were observed. Patients with MNS, Kidd, or Lewis blood group antibodies were screened for corresponding negative donors using monoclonal antibodies for extended typing transfusion based on RhCcEe typing, and the changes in unexpected antibody yield rate after transfusion were observed. Blood group genotyping was performed when serological techniques failed to resolve discrepancies or detect abnormal antigen expression. Results: After RhCcDEe-matched transfusions, RhCE antibodies disappeared in 62 patients, while 1 patient developed anti-Ce. The latter did not develop blood type isotype immunity after receiving RhccEE donor blood. Among the 62 patients, 9 developed unexpected antibodies against other systems: anti-M (4 cases), anti-Mur (2), anti-S (1), anti-Jka (1), and anti-Lea (1). No additional alloimmunization occurred after extended antigen-matched transfusions. A patient with serologically weak e phenotype was genotyped as DCe/DcE, with gene sequencing revealing an 827C>A mutation in exon 6 of the RHCE gene, forming the RHCE 01.31 allele. Conclusion: Precise transfusion strategies incorporating RhCE, MNS, Kidd, and Lewis blood group antigen typing can reduce the probability of blood group homologous immunity. RhCE complex antibodies and RhCE variants pose difficulties for clinical RhCE typing transfusion, which can be addressed through cross-matching and genetic analysis.

Objective:To explore the effect of family empowerment model on the improvement of swallowing care ability and care preparedness of primary caregivers of first-episode stroke dysphagia patients, further to explore its impact on patients′s wallowing function and life quality.Methods:This study was a randomized controlled study. From January 2021 to December 2022, 80 main caregivers of patients with dysphagia caused by manual stroke admitted to the Department of Acupuncture and Moxibustion, Shenzhen Hospital of Traditional Chinese Medicine were selected as the research objects, and 40 cases in the control group and 40 cases in the observation group were selected by random number table method. The control group were treated with conventional nursing care of first-episode stroke dysphagia patients in the acupuncture and moxibustion Department. On the basis of the conventional care in the control group, the observation group were treated with family empowerment model intervention for 14 days and was followed up for 28 days. Primary caregivers′ swallowing care ability, Caregiver Preparedness Scale (CPS), patients′ swallowing function rate, Swallowing Related Quality of Life (SWALQOL) were used to evaluate the effects before intervention and at the end of intervention.Results:There were 18 males and 19 females primary caregivers in the control group, aged (55.61 ± 7.43) years old. There were 18 males and 21 females primary caregivers in the observation group, aged (58.23 ± 8.22) years old. The swallowing care ability score showed a statistically significant difference between the observation group (143.47 ± 3.96) and the control group (107.74 ± 1.43) ( t=-26.76, P<0.05). After intervention, the caregiver preparedness scale was (26.11 ± 3.81) in the observation group, and (18.35 ± 4.54) in the control group, and the difference was statistically significant ( t=-4.11, P<0.05).The patients′ swallowing function rate and SWALQOL score were respectively 97.44% (38/39) and (91.41 ± 8.08) points in the observation group, and 72.97% (27/37) and (80.33 ± 4.21) points in the control group, and the difference was both statistically significant ( χ2=10.76, t=-2.54, both P<0.05). Conclusions:The implementation of family empowerment model could enhance the swallowing care ability and care preparedness of primary caregivers of the first-episode stroke dysphagia patients, which could further improve patients′ swallowing function and life quality.

Background and aim:Hepatitis B virus(HBV)-related gestational acute-on-chronic liver failure(ACLF)is a severe condition with limited treatment options.This study aimed to evaluate the efficacy and ideal timing of plasma exchange and continuous renal replacement therapy(CRRT)in managing pregnant women with HBV-related ACLF. Methods:This study retrospectively analyzed 51 eligible patients with HBV-related gestational ACLF between 2009 and 2020.Patients admitted to the study were divided into a conventional treatment group and a new treatment group according to whether they received the new management protocol,which included more aggressive plasma exchange(PE)and CRRT strategies.All 19 pregnant women with hepatic encephalopathy(HE)were divided into an early treatment group and a non-early treatment group according to whether PE therapy was initiated within three days.Our study had two primary objectives.Firstly,we aimed to evaluate the impact of PE and CRRT on puerperal survival.Secondly,we sought to assess the effects of early PE and CRRT regimens on puerperal survival in women with HE. Results:The levels of total bilirubin on the second day postpartum(D3),the third day postpartum(D4),and the fifth day postpartum(D6)were significantly lower in the new treatment group compared to the conventional treatment group(P=0.02,0.01,and 0.02,respectively).The ALT of D3 was significantly elevated in the new treatment group compared to the conventional treatment group(P=0.02).The incidence of HE overall increased from prenatal to postpartum D4,peaked on D4,and then gradually decreased from the fourth day postpartum(D5)(P=0.027).The first week after delivery revealed a significant difference in survival rate between the two groups,the conventional treatment group had statistically higher mortality rates compared to the new treatment group(P=0.002).Similarly,the entire puerperal period mortality rate of the conventional treatment group was statistically higher than the new treatment group(P=0.002).Moreover,among all patients with HE,the non-early treatment group showed significantly higher puerperal mortality rates compared to the early treatment group(P=0.006). Conclusions:Early PE and CRRT conducted within three days post-childbirth,enhance puerperal prog-nosis for HBV-related gestational ACLF.

Objective To investigate the effect of chaizhu liwei decoction on gastrointestinal motility and p-NF-κBp65 pathway in functional dyspepsia(FD)rats with liver depression and spleen deficiency.Methods Sixty SD rats were random number table method divided into normal group(n=10)and model reserve group(n=50).The FD model of liver depression and spleen deficiency was repli-cated by compound factor stimulation in the model reserve group.After successful replication of the model,50 rats were random number table method divided into model group,traditional Chinese medicine high-dose,medium-dose and low-dose groups and domperidone group,with 10 rats in each group.Each group was given corresponding drugs by gavage,and the general state of rats was observed.The food intake,body mass,gastric emptying rate and intestinal propulsion rate were calculated.The levels of interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)in gastric antrum tissue of rats were detected by enzyme-linked immunosorbent assay(ELISA).Western blot and real-time quantitative polymerase chain reaction(RT-qPCR)were used to detect the expression of p-NF-κBp65 protein and p-NF-κBp65 mRNA in gastric antrum tissue of rats.HE staining was used to observe the morphology of gastric antrum.Results Compared with the normal group,the food intake,body mass,gastric emptying rate and intestinal propulsion rate of rats in the model group were decreased,and the levels of IL-6,TNF-α,p-NF-κBp65 protein expression and p-NF-κBp65 mRNA expres-sion in gastric antrum tissue were increased(P＜0.05).Compared with the model group,the food intake,body mass,gastric emptying rate and intestinal propulsion rate of rats in the traditional Chinese medicine groups and domperidone group were increased,and the levels of IL-6,TNF-α,p-NF-κBp65 protein expression and p-NF-κBp65 mRNA expression in gastric antrum tissue were decreased(P＜0.05).The levels of IL-6 and TNF-α in the traditional Chinese medicine high-dose group were lower than those in the domperi-done group(P＜0.05).The protein expression of p-NF-κBp65 in the traditional Chinese medicine high-dose and medium-dose groups was lower than that in the domperidone group(P＜0.05).Conclusion The mechanism of chaizhu liwei decoction in the treat-ment of FD with liver depression and spleen deficiency may be related to the reduction of IL-6,TNF-α levels,p-NF-κBp65 protein expression and p-NF-κBp65 mRNA expression in gastric antrum tissue of rats,and the improvement of gastrointestinal motility function.
