OBJECTIVE: To explore the relationship between serum complement levels at diagnosis and prognosis in patients with aggressive non-Hodgkin lymphoma(NHL). METHODS: The clinical data of 102 patients with aggressive non-Hodgkin lymphoma diagnosed in the First Hospital of Lanzhou University from February 2017 to March 2023 were selected to analyze the correlation between serum complement C3 and C4 levels and prognosis of patients with aggressive NHL at the time of initial diagnosis. The optimal cut-off point of C3 and C4 were obtained by calculating the Jorden index through the receiver operating characteristic（ROC） curve, and 102 patients were divided into low C3 group (C3< 1.07) and high C3 group (C3≥1.07), low C4 group (C4< 0.255) and high C4 group (C4≥0.255). The effects of serum C3 and C4 levels on the prognosis of these patients were analyzed. RESULTS: ROC curve analysis showed that the area under the curve (AUC) of C3 and C4 in predicting the prognosis of aggressive NHL patients was 0.634 (95%CI ：0.525-0.743；P =0.025) and 0.651 (95%CI ：0.541-0.761；P =0.012), respectively. The optimal cut-off points for C3 and C4 were 1.07 and 0.255, respectively. K-M survival analysis showed that groups with high C3 and C4 levels had shorter progression-free survival (PFS) (P =0.0079; P =0.0092) and overall survival (OS) (P =0.021; P =0.021). Multivariate Cox analysis showed that high level serum complement C3 (HR=2.37, 95%CI : 1.07-5.24, P =0.034) and age ≥60 years (HR=2.34, 95%CI : 1.11-4.95, P =0.025) were independent risk factors for PFS in patients with aggressive NHL. High level complement C3 (HR=2.37, 95%CI : 1.09-5.13, P =0.029) and age ≥60 years at diagnosis (HR=2.40, 95%CI : 1.13-5.13, P =0.024) were independent risk factors for OS in patients with aggressive NHL. CONCLUSION The level of serum complement C3 at diagnosis is one of the prognostic factors in patients with aggressive NHL.

The transition of cancer cells from epithelial state to mesenchymal state awarded hepatocellular carcinoma (HCC) stem cell properties and induced tumorigenicity, drug resistance, and high recurrence rate. Reversing the mesenchymal state to epithelial state by inducing mesenchymal-epithelial remodeling could inhibit the progression of HCC. Using high-throughput screening, chrysin was selected from natural products to reverse epithelial-mesenchymal transition (EMT) by selectively increasing CDH1 expression. The target identification suggested chrysin exerted its anti-HCC effect through covalently and specifically binding threonine 205 (Thr205) of alpha-enolase (ENO1). For the first time, we revealed that ENO1 bound β-catenin mRNA, and recruited YTHDF2 to identify the m6A modified β-catenin in the 3'-UTR region to degrade β-catenin mRNA. Eventually, the CDH1 gene expression was improved through the regulation of β-catenin mRNA. ENO1/β-catenin mRNA interaction might be a promising target for cellular plasticity reprogramming. Moreover, chrysin could mediate mesenchymal‒epithelial remodeling through increasing degradation of β-catenin mRNA by promoting the binding of ENO1 and β-catenin mRNA. To the best of our knowledge, chrysin is the first reported small molecule inducing β-catenin mRNA degradation through binding to ENO1. The water-soluble derivative of chrysin may be a natural product-derived lead compound for circumventing metastasis, recurrence, and drug resistance of HCC by mediating mesenchymal‒epithelial remodeling.

OBJECTIVE: To develop a digital intelligent multimodal shift handover system for the intensive care unit (ICU) and evaluate its application effect in ICU shift handovers. METHODS: A research and development team was established, consisting of 1 department director, 1 head nurse, 3 information technology engineers, 3 nurses, and 2 doctors. Team members were assigned responsibilities including overall coordination and planning, platform design and maintenance, pre-application training, collection and organization of clinical feedback, and research investigation respectively. A digital intelligent multimodal shift handover system was developed for ICU based on the Shannon-Weaver linear transmission model. This innovative system integrated automated data collection, intelligent dynamic monitoring, multidimensional condition analysis and visual reporting functions. A cloud platform was used to gather data from multi-parameter vital signs monitors, infusion pumps, ventilators and other devices. Artificial intelligence algorithms were employed to standardize and analyze the data, providing personalized recommendations for healthcare professionals. A self-controlled before-after method was adopted. Before the application of the ICU digital intelligent multimodal shift handover system (from December 2023 to March 2024), the traditional verbal bedside handover was used; from June 2024 to March 2025, the ICU digital intelligent multimodal shift handover system was applied for shift handovers. Questionnaires before the application of the shift handover system were collected in April 2024, and those after the application were collected in April 2025. The shift handover time, handover quality (scored by the nursing handover evaluation scale), satisfaction with doctor-nurse communication (scored by the ICU doctor-nurse scale) before and after the application of the handover system were compared, and nurses' satisfaction with the shift handover system (scored by the clinical nursing information system effectiveness evaluation scale) was investigated. RESULTS: After the application of the ICU digital intelligent multimodal shift handover system, the shift handover time was significantly shorter than that before the application [minutes: 20 (15, 25) vs. 30 (22, 40)], the handover quality was significantly higher than that before the application [score: 84.0 (78.0, 88.5) vs. 71.0 (55.0, 79.0)], and the satisfaction with doctor-nurse communication was also significantly higher than that before the application (score: 84.58±6.79 vs. 74.50±11.30). All differences were statistically significant (all P < 0.05). In addition, the nurses' system effectiveness evaluation scale score was 102.30±10.56, which indicated that nurses had a very high level of satisfaction with the ICU digital intelligent multimodal shift handover system. CONCLUSIONS The application of the ICU digital intelligent multimodal shift handover system can shorten the shift handover time, improve the handover quality, and enhance the satisfaction with doctor-nurse communication. Nurses have a high level of satisfaction with this system.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Objective To statistically analyze the allergen-specific IgE test results for allergic patients and observe the distribution of allergens and their prevalence trends.Methods Allergen-specific IgE test results were collected from 12 486 patients with suspected allergic diseases who attended the outpatient clinic of the Department of Dermatology of the Second Affiliated Hospital of Air Force Medical University from January 2018 to December 2023,and the distribution of the positivity rate of various allergens and their differences among different age,gender and seasonal subgroups were statistically analyzed.Results Allergen-specific IgE positive results were found in 5 109 cases out of 12 486 patients with suspected allergic diseases,with a positive rate of 40.92%.Between different gender groups,the allergen positivity rate were 45.41%(2 371/5 221)in males and 37.69%(2 738/7 265)in females,respectively,and the difference in positivity rate between males and females was statistically significant(x2=74.99,P<0.001).The allergen positivity rate among different age groups was highest in the 3～<6 years group(60.00%),followed by the 6～<18 years group(54.92%),and lowest in the≥60 years group(29.18%),with statistically significant differences in allergen positivity rates among different age groups(x2=344.97,P<0.001).The top three overall allergen positivity rates were milk(11.73%),dwarf ragweed/artemisia/rudolfia/quinoa(11.43%)and house dust mite(10.82%),and the positivity rates of milk and house dust mite had a tendency to increase year by year.The highest allergen positivity rate among groups in different seasons was in summer(42.28%),followed by fall(41.32%)and lowest in winter(38.31%),and the difference in allergen positivity rates among the four seasons was statistically significant(x2=9.09,P=0.028).Dwarf ragweed/artemisia/rutabaga/quinoa had the highest positivity rate in the fall(15.75%),while milk(14.59%)and egg white(2.58%)had the highest positivity rates in the summer,and the differences in the positivity rates of dwarf ragweed/artemisia/rutabaga/quinoa,milk and egg white between the four seasons were statistically significant(x2=92.50,70.45,8.10,all P<0.05).Multiple positives were present for allergen-specific IgE,with 22.18%single positives and 18.92%double and more than double positives.Positive test results for ingestion were mainly distributed in the lower levels,while positive test results for inhalation were more distributed in the higher levels,especially for dwarf ragweed/artemisia/rutabaga/quinoa,which were most distributed in level 6.Conclusion Different types of allergens have different distribution characteristics among different genders,ages and seasons,the distribution levels of positive results are different,and there are multiple positive results.Based on the distribution characteristics of allergens in the region,rational arrangement of the dietary and living shoule be mode to avoid the risks and to reduce the probability of the occurrence of allergic diseases.
