Objective: To investigate the impact of current laboratory testing models and screening strategies on blood safety by analyzing repeat nucleic acid testing (NAT) results obtained from blood donors who had dual-reactive enzyme-linked immunosorbent assay (ELISA) results but were initially nonreactive by NAT. Methods: Samples from blood donors with dual-reactive ELISA results and initially nonreactive NAT results collected at Dalian Blood Center from 2017 to 2025 were included. Repeated testing was performed using two NAT systems: transcription-mediated amplification (TMA) and polymerase chain reaction (PCR). The results were analyzed in terms of the frequency of reactive NAT results and the testing strategies, including minipool and individual donation testing. Results: A total of 199 samples with dual-reactive ELISA results and initially nonreactive NAT results were included，comprising 66 HBsAg-reactive samples，130 anti-HCV-reactive samples，and 3 HIV Ag/Ab-reactive samples. Among the HBsAg-reactive samples，57（57/66，86.4%）showed at least one reactive NAT result upon repeated testing，and 49 showed two or more repeat reactive results. Anti-HBc was reactive in 64 samples（64/66，97.0%）and nonreactive in 2 samples（2/66，3.0%）；both anti-HBc-nonreactive samples remained nonreactive in repeated NAT. No stable repeat nucleic acid reactivity was observed in anti-HCV- or HIV Ag/Abreactive samples. The TMA system detected 50 reactive samples（50/66，75.8%）through three combined assays plus one discriminatory assay, whereas the PCR system detected 51 reactive samples (51/66, 77.3%) through four rounds of individual-donation testing. Fortyfour samples were reactive on both systems, 6 were reactive only on the TMA system, and 7 were reactive only on the PCR system. Conclusion: Among blood donors with dual-reactive ELISA results and initially non-reactive NAT results, HBsAg-reactive samples contain a high proportion of low viral load HBV-related cases, with intermittent and probabilistic nucleic acid detectability. Both testing frequency and detection strategy significantly affect the detection of low viral load samples. These findings highlight the importance of recognizing the detection characteristics of low viral load HBV-related samples in order to optimize blood screening strategies and improve blood safety.

Objective To compare the efficacy of recombinant human interleukin-11(rhIL-11)and herombopag olamine tablets on chemotherapy-induced thrombocytopenia(CIT)in breast cancer.Methods Eighty-six prospectively selected breast cancer patients with CIT were randomly divided into the control group(administered rhIL-11)and the study group(administered herombopag olamine tablets),with 43 cases in each group.Before treatment and 14 days after treatment,platelet parameters[platelet count(PLT),plateletcrit(PCT),platelet distribution width(PDW)and mean platelet volume(MPV)]and flow cytometry were measured by automated hematology analyzer.Cellular immune indicators(CD3+,CD4+,CD8+and CD4+/CD8+)were detected by flow cytometer.Enzyme-linked immunosorbent assay was used to determine the levels of thrombopoietin(TPO)and interleukin-11(IL-11).The above parameters were compared between the two groups,and the incidence of adverse reactions in the two groups was recorded.Results After treatment,PLT,PCT,CD3+,CD4+,CD4+/CD8+,TPO and IL-11 in both groups were higher than before treatment,and which was higher in the study group than the control group(P＜0.05).After treatment,PDW,MPV and CD8+of both groups were lower than before treatment,and the study group was lower than the control group(P＜0.05).There was no significant difference in the overall incidence of adverse reactions between the two groups(P＞0.05).Conclusion Both rhIL-11 and herombopag olamine tablets are effective in treating breast cancer with CIT.Compared with rhIL-11,herombopag olamine tablets have more advantages in improving platelet parameters,cellular immune indicators,TPO and IL-11,and do not increase the adverse reactions.

One of its primary surgical treatments of tricuspid regurgitation is tricuspid valve biological valve replacement. Catheter tricuspid valve-in-valve implantation is a novel interventional alternative for biological valve failure. The non-invasive lung fluid measuring device remote dielectric sensing (ReDSTM) has been increasingly incorporated into clinical practice as a means of monitoring chronic heart failure in recent years. This report describes the process and outcomes of the first instance of perioperative lung fluid volume evaluation following transcatheter tricuspid valve implantation utilizing ReDSTM technology. The patient has a short-term, substantial increase in postoperative lung fluid volume as compared to baseline.

Objective:To explore the prognostic value of the age-adjusted Charlson comorbidity index (ACCI) in patients with stage IIB cervical squamous cell carcinoma (CSCC) who received radical concurrent chemoradiotherapy (rCCRT).Methods:Clinical data of 115 patients with stage IIB CSCC who underwent rCCRT at the First Affiliated Hospital of Xinxiang Medical University from January 2017 to January 2023 were retrospectively analyzed. Fourteen clinical factors, including ACCI, were assessed. Univariate and multivariate Cox regression analyses were performed to identify the independent prognostic factors for progression-free survival (PFS) and overall survival (OS). The optimal cut-off value for ACCI was determined using the receiver operating characteristic (ROC) curve analysis, and patients were divided into the high ACCI (ACCI > 3) and low ACCI (ACCI ≤ 3) groups. Survival differences between two groups were evaluated using Kaplan-Meier curves and compared by log-rank tests.Results:Multivariate Cox regression analysis revealed that ACCI was an independent prognostic factor for both PFS and OS ( HR=3.405, 95% CI: 1.108-10.467, P=0.032; HR=4.732, 95% CI: 1.363-16.425, P=0.014). Significant differences were observed in PFS and OS between the high and low ACCI groups ( P=0.023 and 0.003, respectively). The median PFS was 44 months in the high ACCI group and 56 months in the low ACCI group. The 2-year and 3-year PFS rates were 81.9% and 80.1% in the high ACCI group, and 94.4% and 94.4% in the low ACCI group, respectively. The median OS was 46 months in the high ACCI group and 56 months in the low ACCI group. The 2-year and 3-year OS rates were 88.3% and 84.7% in the high ACCI group, and 94.4% and 94.4% in the low ACCI group, respectively. Conclusions:For patients with stage IIB CSCC receiving rCCRT, ACCI is an independent and significant prognostic factor, with patients in the high ACCI group exhibiting worse prognosis.

Objective:To evaluate the role of hippocampal β4-Subunit-Containing Nicotinic Acetylcholine Receptors (Chrnb4) in postoperative delirium in aged mice.Methods:Forty-eight SPF male C57BL/6J mice, aged 18 months, weighing 29-35 g, were assigned into 6 groups using a random number table method: tibial fracture group (TF group, n=6), sham operation group (Sham group, n=6), tibial fracture + adipenine group (TA group, n=9), tibial fracture + control vehicle group (TV group, n=9), sham operation + adipenine group (SA group, n=9), and sham operation + control vehicle group (SV group, n=9). The postoperative delirium model was prepared by tibial fracture under sevoflurane anesthesia. Tibial fracture was simulated by implanting a steel pin into the tibia and then clamping it, while sham group only received a longitudinal incision and suture after anesthesia. A microinjection cannula was implanted into the mouse skull at 5 days before developing the model in TA group, TV group, SA group and SV group. Three mice from each group were randomly selected for microelectrode implantation in the hippocampal CA1 area. Starting from 30 min after surgery, adipenine (62.5 nmol/μl) 2 μl was infused into the cerebral ventricle for 7 consecutive days in TA and SA groups, and vehicle (2 μl) was administered instead at a 24-h interval for 7 consecutive days in TV and SV groups. The expression of Chrnb4 mRNA in the hippocampal tissues was detected by real-time quantitative polymerase chain reaction at 24 h after surgery. On the 7th and 8th days after surgery, the open-field test and O-maze experiment were conducted to assess the impulsive-like behavior in TA, TV, SA and SV groups. After the behavioral test, the expression of glial fibrillary acidic protein (GFAP) and vesicular glutamate transporter 1 (Vglut1) in the hippocampal CA1 region was detected by immunofluorescence staining. The local field potentials in the hippocampal CA1 region were recorded during the open field test. Results:The expression of Chrnb4 mRNA in the hippocampal tissues was significantly up-regulated in TF group compared to Sham group ( P<0.05). Compared with TV group, the percentage of central path distance in the open field test and percentage of time spent in the open arms of the O-maze were significantly decreased, the power of β-waves in the CA1 field potentials was decreased, the expression of GFAP and Vglut1 in the hippocampal CA1 region was down-regulated, and the co-staining area of GFAP + and Vglut1 + was decreased in TA group and SV group ( P<0.05). There was no significant difference in each parameter between SA group and SV group ( P>0.05). Conclusions:Hippocampal Chrnb4 may be involved in the mechanism of postoperative delirium in aged mice, and this process may be related to inhibition of neuron excitotoxicity.
