ObjectiveTo investigate the changes in coagulation system in acute decompensated cirrhosis (ADC) patients with or without sepsis and the association of these changes with short-term prognosis. MethodsA prospective study was conducted among 116 ADC patients who were hospitalized in Nanfang Hospital from January 2021 to July 2023, among whom there were 86 patients with sepsis and 30 patients without sepsis, and 54 patients with sepsis alone who had no chronic liver disease were enrolled as control group. Thromboelastography (TEG) and other conventional coagulation parameters were used to comprehensively evaluate the coagulation function of patients. The data including TEG results and short-term prognosis were collected, and a correlation analysis was performed. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. The Spearman correlation coefficient was calculated to investigate the correlation between different variables. The Logistic regression model was used to perform the univariate and multivariate analyses. ResultsFor the ADC patients with sepsis, the lungs and bloodstream were the main infection sites, and bacteria were the main pathogenic microorganism. TEG results showed that compared with the patients with sepsis alone, the patients with ADC and sepsis had a significant reduction in median maximum amplitude (MA), a significant increase in coagulation time (K time), and a significant reduction in α angle (all P<0.05); the patients with ADC and sepsis had a significantly longer reaction time (R time) than those with ADC alone (P=0.02), and the patients with sepsis alone had a significantly longer R time than those with ADC and sepsis (P=0.04). There was no correlation between MA and platelet count in the patients with ADC and sepsis (r=-0.133, P=0.057), while there was a significant correlation between MA and platelet count in the patients with sepsis alone (r=0.595, P=0.001). SOFA score was negatively correlated with MA in sepsis patients with or without ADC (r=-0.503 and -0.561, both P<0.001), and for the patients with ADC and sepsis, R time, K time, and α angle were weakly correlated with SOFA score and had a relatively strong correlation with APTT (all P<0.05). The patients with ADC alone all survived within 90 days, and compared with the death group, the patients with sepsis alone who survived had significantly higher values of MA and α angle (all P<0.05); there was a significant difference in α angle on day 90 between the survival group and the death group, no matter whether the patients were comorbid with ADC or not (both P<0.01), while for the patients with ADC and sepsis, there was no significant difference in MA value on day 90 between the survival group and the death group (P>0.05). ConclusionFor ADC patients comorbid with sepsis, coagulation function assessment and monitoring should be taken seriously in clinical practice, and TEG parameters and SOFA score should be monitored when necessary to develop individualized treatment regimens.

Objective:To explore the correlation between high cholinergic pathway signaling and cognitive function in patients with Parkinson disease(PD) accompanied with sleep disorder.Methods:PD patients admitted from 2017 to 2022 were divided into PD with sleep disorder group (PD-SD group) ( n=56) and PD without sleep disorder group (PD-NSD group) ( n=41) according to the Parkinson's disease sleep scale (PDSS) score. All participants underwent magnetic resonance imaging examination.All patients were evaluated by the PDSS, Hoehn-Yahr (H-Y), Montreal cognitive assessment scale (MoCA), and cholinergic pathways hyper intensities scale (CHIPS). The difference of cognitive function between the two groups and the correlation between CHIPS and cognitive function were analyzed.Independent sample t-test, Spearman correlation analysis, and binary Logistic regression analysis were performed on the data by SPSS 26.0 statistical software. Results:(1)The MoCA score of the PD-SD group (22.00 (5.00)) was lower than that of the PD-NSD group (26.00 (5.00)) ( Z=-3.830, P<0.05). The total and all aspects scores of CHIPS in PD-SD group were higher than those in PD-NSD group(the total score of the low external capsule: 12.00(8.00), 0(8.00), the total score of the high external capsule: 12.00(2.00), 6.00(9.00), the total score of the radial crown: 8.00(0), 4.00(4.00), the total score of the centrum semiovale: 3.00(4.00), 0(2.00), the total score of the right side: 16.00(9.00), 5.00(10.00), the total score of the left side: 17.00(6.00), 7.00(9.00), the total score of CHIPS: 32.00(14.00), 14.00(20.00))( Z=-5.081, -5.873, -4.933, -3.211, -5.562, -6.232, -5.995, all P<0.05). (2)The correlation analysis between the score of CHIPS and cognitive function in the PD-SD group showed that, the total score of the low external capsule ( r=-0.286), the total score of the centrum semiovale ( r=-0.307), the total score of the right side ( r=-0.376), the total score of the left side ( r=-0.284) and the total score of CHIPS ( r=-0.349) were negatively correlated with MoCA(all P<0.05). (3)Binary Logistic regression analysis showed that white matter lesions in centrum semiovale, low inner capsule, right and left leukodystrophy were not influence factors for cognitive impairment (all P>0.05). Conclusion:PD patients with sleep disorders have lower cognitive function scores, higher CHIPS scores, and significant changes in white matter lesions compared to those without sleep disorders. In PD patients with sleep disorders, the higher the CHIPS score, the lower the cognitive function score, and the more significant the rate of cognitive impairment occurrence and development.

Objective:To investigate the development of receptive and expressive vocabulary in Mandarin-speaking children with cochlear implants (CI) during the first year after CI activation.Methods:A total of 827 children (411 boys and 416 girls) who were implanted CI before 2.5 years of age from October 2019 to December 2022 in the Department of Auditory Implantation, Shandong Provincial ENT Hospital were included in this study. The Infant Checklist of the Mandarin Early Vocabulary Inventory (EVI) was used to assess the quantity and content of receptive and expressive vocabulary at the time of CI activation and at the 1st, 3rd, 6th, 9th, 12th months post-activation. SPSS 22.0 was used to describe the receptive and expressive vocabulary of CI children at the first year after activation.Results:During the first year after CI activation, CI children′s receptive and expressive vocabulary consistently increased with the CI usage. The average number of receptive vocabulary and expressive vocabulary respectively increased from 0 to 178, and from 0 to 97. At the first year of post-activation, the number of receptive and expressive vocabulary of CI children were superior to that of hearing-age matched typical-hearing children, but fell behind of that of chronological age matched typical-hearing children. In terms of lexical categories, receptive and expressive vocabulary was acquired in the following order: nouns, verbs, adjectives, and pronouns. Among the top 50 words that CI children could express, nouns were the most common, then followed by verbs, adjectives, and pronouns. Father′s education level can significantly and positively predictethe receptive vocabulary of CI children at the first year post-activation. At the first year after CI activation, the 10th, 25th, 50th, 75th, and 90th percentiles were 113, 149, 178, 202, 223 for the receptive vocabulary, and 9, 37, 97, 148, 188 for expressive vocabulary.Conclusion:For Mandarin speaking children with CI, the receptive and expression vocabulary continuely increased within the first year after CI activation. The ability to grasp receptive vocabulary precedes the ability to express expressive vocabulary. Compared to hearing-age matched typical-hearing children, CI children showed faster rate of the vocabulary growth, and earlier and more frequently verb expression. However, it still larged behind that of chronological age matched hearing normal children. CI children respectively understood and expressed nouns and verbs the first. In children with CI, the first concepts understood and expressed were nouns and verbs. Among the first 50 words expressed, nouns were the most numerous, and the age at which verbs were acquired was earlier than that for hearing-age matched typical-hearing children.

[Objective] To analyze the changes of platelet extracellular vesicles (PEVs) content in apheresis at different storage periods, track the PEVs and transfusion efficacy of patients, and explore the mechanism of PEVs in relation to platelet storage damage and transfusion efficacy. [Methods] From November 2022 to April 2024, a total of 85 apheresis platelets samples were collected at Jiading District Blood Station. Flow cytometry was used to detect the content of PEVs on the day of collection and before transfusion. The changes in the content of PEVs stored for 1 to 5 days were observed. Patients with acute leukemia were selected as transfusion recipients, and their content of platelet count and PEVs before transfusion and within 24 hours after transfusion, and the efficacy were tracked to explore the mechanism of PEVs in relation to storage lesion and transfusion efficacy. [Results] The content of PEVs before platelet infusion (8.73±4.84) was significantly higher than that on the day of platelet collection (5.11±3.33), and the difference was statistically significant (P<0.01). The increase in the content of PEVs in storage for 2 to 5 days was 2.55±1.38, 3.49±2.63, 3.86±3.55 and 4.50±3.91, with statistically significant difference (P<0.05). The PEVs content in patients after blood transfusion was positively correlated with that before transfusion and that in apheresis platelet bags during transfusion (P<0.001) A total of 85 cases of apheresis platelet transfusion were conducted, with 61 effective transfusions having a CCI value of (13.43±4.70), and 24 transfusion refractoriness cases having a CCI value of (2.27±3.67), showing a statistically significant difference (P<0.001). The transfusion effectiveness rates for patients receiving different storage periods of apheresis platelets of 2 to 5 days were 88.89%, 68.42%, 68.18% and 57.14% respectively, with corresponding CCI values of 11.18±6.10, 10.43±6.77, 9.53±6.75 and 9.48±8.86, and there was no significant difference between CCI groups (P>0.05). There was no significant correlation between the PEVs content before and after transfusion and the efficacy of CCI (P>0.05). There was no significant correlation between the PEVs content before apheresis platelet transfusion and the efficacy of CCI (P>0.05). [Conclusion] The content of PEVs increased with the prolongation of storage time, which could be used as a potential blood quality evaluation and monitoring index during the storage period, but it was not significantly correlated with the efficacy of CCI in transfusion.

Background:
This study aimed to compare the intercostal nerve block (ICNB) and thoracic paravertebral block (TPVB) for acute herpes zoster-associated pain (ZAP) and possible prophylaxis for post-herpetic neuralgia (PHN).
Methods:
This study enrolled 128 patients with ZAP. Their records were stratified into standard antiviral treatment (AVT) plus US-guided TPVB (the TPVB group), AVT plus US-guided ICNB (the ICNB group) or AVT alone (the control group). Herpes zoster (HZ)-related burden of illness (HZ-BOI) within the post-procedural 30 days was defined as the primary endpoint, determined by a composite of pain severity and follow-up duration. Procedure time, rescue analgesic requirement, PHN incidence, health-related quality of life and side effects were also recorded.
Results:
Significantly lower HZ-BOI-AUC 30 was reported in the TPVB and ICNB groups as compared to the control group, with a mean difference of 57.5 (P < 0.001) and 40.3 (P = 0.003), respectively. However, there was no difference between the TPVB and ICNB groups (P = 0.978). Both TPVB and ICNB reported significantly greater improvements in PHN incidence, EQ-5D-3L scores and rescue analgesic requirements during follow-up, as opposed to the control AVT. Shorter procedure time was observed in ICNB as compared to TPVB (16.47 ± 3.39 vs. 11.69 ± 2.58, P < 0.001).
Conclusions
Both US-guided TPVBs and ICNBs were effective for ZAP, and accounted for possible prophylaxis for PHN, as compared to AVT alone. The ICNB approach could be recommended as an alternative to conventional TPVB with a better consumed procedure time and side effect profile.

Objective:To evaluate the early assessment of hepatocardiac integration based on ultrasonic elasticity and blood flow vector imaging (VFM) technology, in conjunction with unsupervised cluster analysis and supervised machine learning methods.Methods:An observational research design without any intervention was adopted from December 2021 to September 2022, 45 patients with liver cirrhosis, 43 patients with liver fibrosis, and 42 healthy volunteers were selected from the First Affiliated Hospital of Harbin Medical University. Liver combined elasticity technology and VFM technology were used to obtain information on the liver and heart of the subjects, respectively. The acquired data were standardized, and then clustered using topological data analysis (TDA) technology on the processed data. Subsequently, the clustering results were evaluated based on statistical analysis, and finally, supervised multi-classification tasks were realized through machine learning methods.Results:Patients were stratified into five distinct groups based on a network of patient similarities. The average characteristics of each group were as follows: Group 1 exhibited the most severe hepatocardiac conditions relative to the other groups. Groups 2 and 3 displayed moderately severe conditions.In contrast, Group 4 comprised entirely of healthy controls, all of whom presented with normal hepatocardiac function. Group 5 presented a unique case among the categories.Participants in this group showed poor liver conditions. However, according to the guidelines for cardiac diastolic function assessment, their heart function was generally unremarkable, with only a minority of indicators deviating significantly. Support Vector Machine (SVM), Random Forest Tree (RFT), and Multilayer Perceptron (MLP) were employed for multi-classification tasks on the test dataset. The average accuracies achieved by these models were 70%, 81%, and 84%, respectively.Conclusions:By combining liver combined ultrasonic elasticity, cardiac VFM technology and TDA technology to construct a patient similarity network, we successfully identified patients with liver fibrosis who did not show abnormalities in conventional cardiac indicators but may have potential abnormal cardiac function, which has important implications for guiding the selection of clinical intervention measures, and optimizing patient management stratification.

Objective:To establish the prediction model for postoperative delirium in elderly patients with mild stroke undergoing non-cardiac and non-intracranial surgery.Methods:This was a nested case-control study. Seven hundred and fifty elderly patients of either sex with mild stroke, aged ≥65 yr, undergoing elective surgical procedures under general anesthesia in the Department of Gastrointestinal Surgery, Orthopedics and Urology at the Tangshan Workers Hospital from May to December 2023, were selected. The perioperative clinical data were collected. The incidence of postoperative delirium was assessed using the Confusion Assessment Scale 1-7 days after surgery or 1 day before discharge. The patients were assigned to the training set and the validation set in a ratio of 7∶3 using a simple random sampling method. Multivariate logistic regression was used to identify the risk factors for postoperative delirium, a postoperative delirium risk prediction model was established based on the risk factors, the nomogram was developed, and the receiver operating characteristic (ROC) curve, calibration curve and decision curve were plotted to assess the accuracy of the prediction model. The prediction model was verified using the validation set, and the calibration curve and ROC curve were plotted to assess the predictive performance of the model.Results:A total of 721 patients were finally included, and 108 patients developed postoperative delirium. Older age, high American Society of Anesthesiologists Physical Status classification, history of preoperative hypertension, short years of education, high preoperative Pittsburgh sleep quality index score, high preoperative National Institutes of Health Stroke Scale score, high intraoperative hypothermia, intraoperative hypotension and high postoperative numerical rating scale score were independent risk factors for postoperative delirium ( P<0.05). The area under the ROC curve of the training set prediction model was 0.996, with a sensitivity of 1.000, and specificity of 0.945. The slope of the calibration curve was close to 1, and the predicted risk of postoperative delirium was in good agreement with the actual risk. When the threshold probability of the decision curve was 0-0.9, the net return rate was higher than the null line. Validation set: In the calibration curve of the prediction model, the cohort and calibration curves were close to the ideal line, with an area under the ROC curve of 0.997, sensitivity of 1.000, and specificity of 0.962. Conclusions:Based on age, American Society of Anesthesiologists Physical Status classification, history of preoperative hypertension, years of education, preoperative Pittsburgh sleep quality index score, National Institutes of Health Stroke Scale score, intraoperative hypothermia and hypotension and postoperative numerical rating scale score, the prediction model for postoperative delirium is developed and has a good predictive performance in elderly patients with mild stroke undergoing non-cardiac and non-intracranial surgery.
