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 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.

【Objective】 To investigate the expressions of containing CKLF like MARVEL transmembrane domain gene 6 (CMTM6) and ras protein activator like 2 (RASAL2) in prostate cancer tissues, and to analyze the relationships between the above factors and the clinicopathological characteristics and prognosis of prostate cancer patients. 【Methods】 The prostate cancer tissues and adjacent tissues of 80 prostate cancer patients admitted to Zhumadian City Center Hospital during Feb.2018 and Feb.2020 were collected.Expressions of CMTM6 and RASAL2 were detected with immunohistochemical method.The relationship between the expressions of CMTM6 and RASAL2 and the clinical pathological characteristics of prostate cancer were analyzed.The survival curve was plotted with Kaplan-Meier method.The prognostic factors were analyzed with multivariate Cox regression. 【Results】 The positive expression rate of CMTM6 in prostate cancer tissues was 67.50%, which was obviously higher than 38.75% in adjacent tissues (χ²=13.277, P<0.001).The positive expression rate of RASAL2 in prostate cancer tissues was 47.50%, which was obviously lower than 73.75% in adjacent tissues (χ²=11.546, P=0.001).The expressions of CMTM6 and RASAL2 were not related to patients’ age, tumor size and tissue differentiation (P>0.05), but to TNM staging, Gleason score, lymph node metastasis and preoperative PSA level (P<0.05).Survival curve showed that the 3-year survival rate of positive CMTM6 expression patients was 61.11% (33/54), which was obviously lower than that of negative patients, which was 88.46% (23/26) (χ²=5.940, P=0.015).The 3-year survival rate of positive RASAL2 expression patients was 81.85% (31/38), which was obviously higher than that of negative patients, which was 59.52% (25/42) (χ²=4.887, P=0.027).Cox multivariate regression showed that Gleason score, lymph node metastasis, preoperative PSA level, CMTM6, and RASAL2 were independent influencing factors of prognosis (P<0.05). 【Conclusion】 The positive expression rate of CMTM6 in prostate cancer tissues is significantly higher than that in paracancer tissues, while the positive expression rate of RASAL2 in prostate cancer tissues is significantly lower than that in paracancer tissues. Both CMTM6 and RASAL2 are closely related to the clinical pathological characteristics and prognosis of prostate cancer patients, and may provide reference for the prognosis.

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 study the protective effects and mechanism of Melastoma sanguineum Sims fruit extract (MSE) on chronic chemical liver injury induced by ethanol, acetaminophen and carbon tetrachloride in mice; To discuss it mechanism.Methods:Totally 96 mice were divided into normal control group, ethanol model group, ethanol+bifendate control group and ethanol+MSE high-, medium- and low-dosage groups, APAP model group, APAP+bifendate control group and APAP+MSE high-, medium- and low-dosage groups, CCl 4 model group, CCl 4+bifendate control group and CCl 4+MSE high-, medium- and low-dosage groups, with 6 mice in each group. Except for the normal control group, the other groups were respectively prepared for the ethanol model, the APAP model and the CCl 4 model. The mice in the MSE high-, medium- and low-dosage groups were intragastrically administrated with 10, 5 and 2.5 g/kg of MSE, respectively; the bifendate control group was intraperitoneally injected with 15 mg/ml bifendate solution at 75 mg/kg; the normal control group was intraperitoneally injected with equal volume of normal saline/peanut oil solution once a day for 25 consecutive days. The levels of GPT, GOT and total bilirubin (TBIL) in serum were detected; the activities of SOD and GSH-Px and the content of MDA in liver tissue were detected; the mRNA expressions of TNF-α, IL-6, alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) were detected by qRT-PCR; the protein expressions of cytochrome P450 CYP1A1, CYP1A2, and CYP3A in liver tissue were detected by Western blot; the pathological changes of the liver tissue were observed by HE staining. Results:Compared with the corresponding ethanol, APAP and CCl 4 model groups, the serum GPT, GOT and TBIL levels of mice in the ethanol+bifendate control group and ethanol+MSE high- and medium-dosage groups, the APAP+bifendate control group and APAP+MSE high- and medium-dosage groups, and the CCl 4+bifendate control group and CCl 4+MSE high- and medium-dosage groups decreased ( P<0.01 or P<0.05), the activities of SOD and GSH-Px in the liver tissue increased ( P<0.01 or P<0.05), and the MDA level decreased ( P<0.01 or P<0.05), and the mRNA levels of IL-6 and TNF-α decreased ( P<0.01); the mRNA levels of ADH and ALDH in the ethanol+MSE high-, medium-, and low-dosage groups decreased ( P<0.01). Compared with the APAP model group, the expressions of CYP1A1 and CYP1A2 in the APAP+MSE groups increased ( P<0.01), and the expression of CYP3A protein decreased ( P<0.05); compared with the CCl 4 model group, the expressions of CYP1A1, CYP1A2 and CYP3A proteins in the CCl 4+MSE groups decreased ( P<0.05). Conclusion:MSE has a protective effect on chronic chemically-induced liver injury induced by ethanol, APAP, and CCl 4 in mice, and its mechanism may be related to antioxidant stress, inhibition of inflammatory response, and regulation of the expression of cytochrome P450-related enzymes.

Objective:To explore the influence of temperament between parenting style and externalizing problem behaviors in school-age children.Methods:In October 2017, a stratified cluster sampling method was used to conduct a questionnaire survey among 380 school-age children in Aruhorqin Banner, Chifeng City, Inner Mongolia Autonomous Region. All the school-age children were assessed by the Achenbach child behavior checklist, parenting style scale, and middle childhood temperament questionnaire.Mediation models were established by the PROCESS macro program of SPSS, and the mediating effect was tested by the Bootstrap method.Results:The scores of various scales for school-age children were as follows: father's authoritative parenting style(3.77±1.11), father's authoritarian parenting style(1.55±0.68), father's indulgent parenting style(1.25±0.57), mother's authoritative parenting style(3.86±1.16), mother's authoritarian parenting style(1.64±0.73), mother's indulgent parenting style(1.25±0.61), activity level(2.42±0.71), attention dispersion(3.78±0.81), externalization problem behaviors 3.0(4.0).For school-age children, the scores of externalization problem behaviors were negatively correlated with the scores of authoritative parenting style( r=-0.15, -0.11, both P<0.05), and positively correlated with authoritarian and indulgent parenting style ( r=0.17-0.33, all P<0.05). The scores of externalization problem behaviors were positively correlated with eight temperament dimensions, such as adaptability, emotional essence, reaction threshold, attention dispersion, persistence, rhythmicity, activity level and reaction intensity( r=0.17-0.42, all P<0.05). After controlling for age and gender, attention dispersion played a masking effect on the influence of authoritative parenting style on children's externalizing problem behaviors, with the indirect effect accounting for 21.05%(|0.04/-0.19|) and 26.67%(|0.04/-0.15|) of the direct effect respectively. Attention dispersion partially mediated the impact of father's authoritarian parenting style on children's externalization problem behaviors, with the mediating effect accounting for 10.71%(0.03/0.28) of the total effect. Response intensity partially mediated the impact of authoritarian parenting style on children's externalizing problem behaviors, with the mediating effect accounting for 25.00%(0.07/0.28) and 27.58%(0.08/0.29) of the total effect respectively. Conclusion:Temperament plays a mediating role between parenting styles and externalizing problem behaviors among school-age children. A nurturing environment suitable for children's temperament should be created to prevent the occurrence of externalizing problem behaviors among school-age children.

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 evaluate the role of the AMP-activated protein kinase (AMPK)-silent information regulator 1 (SIRT1)-nuclear factor-κB (NF-κB) signaling pathway in reduction of brain injury by panax notoginseng saponins (PNS) in mechanically ventilated rats.Methods:Seventy-two SPF-grade male Sprague-Dawley rats, aged 10 weeks, weighing 357-377 g, were divided into 6 groups ( n=12 each) by a random number table method: sham operation group, model group, PNS low dose group, PNS medium dose group, PNS high dose group, and PNS high dose+ compound C group. PNS 12.5, 25 and 50 mg/kg were intraperitoneally injected in PNS low dose group, PNS medium dose group and PNS high dose group, respectively.
