OBJECTIVE: To evaluate the risks and benefits of different resuscitation fluids in patients with early sepsis and septic shock by observing and comparing clinical indicators, clinical outcomes, and the concentration changes of glycocalyx biomarkers, and to determine how to appropriately select suitable resuscitation fluids for sepsis patients to aid fluid therapy. METHODS: A single center, prospective, randomized controlled trial was conducted. Patients with early sepsis and septic shock who have required fluid resuscitation after capacity status assessment admitted to the department of critical care medicine of Fourth Hospital of Hebei Medical University from April to October 2023 were enrolled. Patients were randomly assigned to either the experimental group (balanced crystalloid solution+albumin) or the control group (balanced crystalloid solution) by a random number table method. Clinical data of both groups of patients before and after resuscitation at 3, 8, and 24 hours were monitored, and blood samples were collected, enzyme-linked immunosorbent assay (ELISA) was used to measure the concentration of plasma glycocalyx biomarker syndecan-1. The 28-day and 90-day survival rates and complications were also assessed. RESULTS: A total of 66 patients were enrolled, including 44 in the experimental group and 22 in the control group. The baseline data of two groups were balanced and comparable. There was no statistically significant difference in the plasma concentration of syndecan-1 between the experimental group and the control group before and after resuscitation, and both showed a trend of first increasing and then decreasing. However, the plasma syndecan-1 level in the control group at 8 hours and 24 hours after resuscitation were significantly higher than the baseline level before resuscitation [ng/L: 19.02 (14.41, 27.80), 18.95 (12.40, 22.50) vs. 14.67 (11.57, 21.14), both P < 0.05], while there was no statistically significant difference at any time point within the experimental group. The correlation analysis between plasma syndecan-1 level and lactic acid, albumin, and sequential organ failure assessment (SOFA) in all patients showed that a positive correlation between syndecan-1 level and SOFA score before resuscitation (r = 0.247, P = 0.046), and a negative correlation between syndecan-1 level and albumin level at 24 hours after resuscitation (r = -0.308, P = 0.012). There were no statistically significant differences in 28-day and 90-day mortality, length of hospital stay, length of intensive care unit (ICU) stay, duration of mechanical ventilation, blood purification time, number of organ injuries, and complications between the two groups. However, the baseline albumin level in the experimental group was significantly lower than that in the control group (g/L: 28.7±4.5 vs. 31.6±4.2, P < 0.05). Analysis of clinical treatment data showed that compared with the control group, the experimental group had lower absolute lactate level at 8 hours and 24 hours after resuscitation [mmol/L: 8 hours was 1.30 (1.00, 1.88) vs. 1.60 (1.30, 3.05), 24 hours was 1.15 (0.80, 1.78) vs. 1.55 (1.08, 2.05), both P < 0.05], and higher lactate clearance rate [8 hours was 45% (27%, 56%) vs. 20% (-4%, 46%), 24 hours was 55% (34%, 70%) vs. 34% (-14%, 59%), both P < 0.05]. However, there were no statistically significant differences in the amount of fluid resuscitation, use of vasoactive drugs, and oxygenation index between the two groups during the resuscitation process. Multivariate Logistic regression analysis showed that body mass index (BMI) was independently correlated with 90-day mortality [odds ratio (OR) = 1.991, 95% confidence interval (95%CI) was 1.023-3.387, P = 0.043]. CONCLUSIONS There are no significant difference in plasma syndecan-1 level during fluid resuscitation of early sepsis and septic shock patients using balanced crystalloid fluid and balanced crystalloid fluid combined with albumin resuscitation, and there are no statistically significant differences in the impact on 28-day and 90-day prognosis, length of hospital stay, complications, and other aspects of the patients. However, compared to balanced crystalloid fluid, the combination of balanced crystalloid fluid and albumin for fluid resuscitation in sepsis patients has lower lactate level and better lactate clearance effect, but further validation is still needed through large-scale randomized controlled trials.

Objective:To investigate the clinical characteristics and independent risk factors of severe disease in patients with anti-nuclear matrix protein (NXP) 2 antibody-positive juvenile dermatomyositis (JDM).Methods:A retrospective cohort study was conducted, including 219 anti-NXP2 antibody-positive JDM patients admitted to 23 children′s hospitals across China from July 2011 to July 2023. Patients were classified into severe and non-severe groups based on classification criteria for severe dermatomyositis. Demographic characteristics, clinical manifestations, and laboratory parameters were compared between the 2 groups using independent sample t-test, Mann-Whitney U test, or χ2 test. Univariate and multivariate Logistic regression analyses were performed to identify risk factors for severe disease. The receiver operating characteristic curve was employed to calculate optimal cut-off values. Results:Among the 219 patients, 108 were male and 111 were female, with an age at onset of 6.3 (3.5, 9.4) years. The severe group comprised 69 patients, and the non-severe group 150 patients. The severe group had significantly higher rates of fever, heliotrope rash, subcutaneous edema, periorbital edema, anti-Ro52 antibody positivity, as well as elevated levels of ferritin-to-albumin ratio (FAR), creatine kinase (CK), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) (all P<0.05). Multivariate analysis identified anti-Ro52 antibody positivity ( OR=13.26, 95% CI 1.37-128.29) and elevated FAR ( OR=1.90, 95% CI 1.09-2.31) as independent risk factors for severe anti-NXP2 antibody-positive JDM (both P<0.05). Receiver operating characteristic curve analysis revealed that a FAR cutoff value of 6.82 predicted severe disease with an area under the curve of 0.87 (95% CI 0.81-0.94, P<0.001), sensitivity of 0.85, and specificity of 0.70. All patients received glucocorticoid therapy, and the severe group received higher proportions of steroid pulse therapy, cyclophosphamide, mycophenolate mofetil, intravenous immunoglobulin, biologics, and adjuvant treatments compared to the non-severe group (all P<0.05). In terms of outcomes, 2 patients (2.9%) in the severe group died (due to neurological involvement and intestinal perforation, respectively), while the remaining patients achieved complete clinical response or remission. All patients in the non-severe group achieved remission. Conclusions:The primary clinical features of anti-NXP2 antibody-positive JDM included fever, heliotrope rash, subcutaneous edema, periorbital edema, anti-Ro52 antibody positivity, and elevated levels of CK, AST, LDH, and FAR. Furthermore, anti-Ro52 antibody positivity and a FAR>6.82 were identified as independent risk factors.

Objective To explore the pathological features of bronchiolar adenoma(BA)and its specific high-resolution computed tomography(HRCT)signs,and to differentiate BA from minimally invasive adenocarcinoma(MIA)using a non-invasive preoperative method.Methods A total of 80 patients with BA and 130 patients with MIA were retrospectively selected,and the clinical information and HRCT features were compared.All cases were divided into development set and test set at a 7︰3 ratio.Logistic regression analysis was used to screen the independent predictors of MIA and construct a model.Results There were significant differences in age,lobe distribution,density,vacuole sign,tumor-related vessels number(TVN),and distance to pleura(DTP)between BA and MIA patients(P<0.05).Age,density,TVN,DTP and long diameter were identified as independent predictors of MIA.A model was constructed,with area under the curve(AUC)of 0.887 and 0.884 in the development and test sets,respectively.Conclusion The model based on HRCT morphological features of BA and MIA demonstrates superior diagnostic performance compared to individual CT morphological features.

Objective To evaluate the application of high-resolution magnetic resonance vessel wall imaging(HRMR-VWI)in identifying high-risk features of intracranial atherosclerotic plaques,and to analyze the correlation between plaque characteristics and stroke recurrence under varying degrees of stenosis.Methods The data from 368 patients with intracranial atherosclerotic stenosis(ICAS)across two centers were retrospectively analyzed.Based on the degree of stenosis,all patients were categorized into mild-to-moderate stenosis group(luminal stenosis<70%,n=155)and severe stenosis group(luminal stenosis≥70%,n=213).HRMR-VWI images and clinical information of the patients were collected and analyzed,and the culprit plaques were quantitatively analyzed.Univariate and multivariate logistic regression analyses were employed to identify the risk factors for stroke recurrence,and the predictive performance was evaluated using the area under the curve(AUC)of the receiver operating characteristic(ROC)curve.Results Higher normalized wall index(NWI)[odds ratio(OR)=1.082,95%confidence interval(CI)1.050-1.118,P<0.05]and the presence of intraplaque hemorrhage(IPH)(OR=1.843,95%CI 1.120-3.036,P<0.05)were risk factors for stroke recurrence in all patients.And these two factors were also significant in the mild-to-moderate stenosis group(NWI:OR=1.088,95%CI 1.009-1.186,P<0.05;IPH:OR=4.049,95%CI 1.227-16.065,P<0.05).A predictive model for stroke recurrence was constructed using the combination of IPH and NWI,with the best performance in the mild-to-moderate stenosis group(AUC=0.813,95%CI 0.723-0.906).Conclusion In patients with luminal stenosis<70%,the increase of NWI and the presence of IPH have been validated as significant and effective indicators for predicting stroke recurrence,demonstrating notable predictive performance.In contrast,among patients with luminal stenosis≥70%,the utility of plaque characteristics in predicting stroke recurrence is relatively lower,indicating that the correlation between plaque characteristics and stroke recurrence varies across different degrees of stenosis.

Objective:To understand the changes in the experience of dietary behavior compliance management in middle-aged and young adults with newly diagnosed type 2 diabetes (T2DM) and provide strategies for healthcare professionals to manage patients' long-term dietary compliance.Methods:A longitudinal qualitative study design was used. Purposeful sampling was conducted to select 16 middle-aged and young adult patients diagnosed with T2DM at the Department of Endocrinology, the Affiliated Huaian No. 1 Hospital of Nanjing Medical University, from January to May 2024. Semi-structured interviews were conducted, and data was analyzed cross-sectionally and longitudinally.Results:A total of 3 main themes and nine sub-themes were identified: emotional changes in dietary compliance (negative emotional experiences, positive emotional coping, and emotional fluctuations transformation) ; management experience of dietary compliance (gradual adaptation to dietary management, disruption of daily eating routine, and lack of family decision-making support) ; diverse support needs for dietary compliance (needs for knowledge and information support, peer and decision-making support, and continuity of care management system) .Conclusions:The experience of dietary behavior compliance management in middle-aged and young adults with T2DM is a continuous, dynamic, and fluctuating process. Healthcare professionals can develop targeted interventions based on patients' real situations and management experiences to improve their compliance levels.

Objective To evaluate the clinical screening value of the Epworth sleepiness scale(ESS)for patients with type 2 diabetes mellitus(T2DM)and obstructive sleep apnea hypopnea syndrome(OSAHS).Methods A total of 399 hospitalized T2DM patients were selected for portable monitoring(PM)and ESS assessment.Based on the presence or absence of OSAHS,the study was divided into a simple T2DM group(T2DM,n=143)and a group with comorbid OSAHS(OSAHS,n=256).According to the apnea-hypopnea index(AHI),the study participants were categorized into a normal group(AHI<5 times/h,n=143),a mild OSAHS group(AHI 5～15 times/h,n=147),a moderate OSAHS group(AHI>15～30 times/h,n=69),and a severe OSAHS group(AHI>30 times/h,n=40).Differences in ESS scores across various OSAHS severity groups were compared.Receiver operating characteristic(ROC)curve analysis was conducted to evaluate the screening value of ESS for OSAHS.Results Body mass index,proportion of obesity,proportion of central obesity,serum creatinine and fasting C-peptide were significantly higher the OSAHS group compared to the non-OSAHS group(P<0.05).Significant statistical differences in ESS scores were observed between the severe and mild OSAHS groups(P=0.006).When an ESS score of≥9 was used as the threshold for screening OSAHS,the concordance rate with PM diagnosis was 40.6%.ROC curve analysis revealed that the area under the curve(AUC)for ESS screening for OSAHS,moderate-to-severe OSAHS,and severe OSAHS,and their respective optimal thresholds(95%CI),were as follows 0.518(95%CI 0.459～0.577,P=0.545),0.571(95%CI 0.507～0.635,P=0.029)and 0.624(95%CI 0.531～0.718,P=0.010),with cutoffs of≥2 points,≥3 points,and≥4 points,respectively.Conclusions An increased ESS score in T2DM patients significantly indicates the likelihood of severe OSAHS.Using an ESS score of≥9 as a threshold to screen for OSAHS is ineffective,whereas an ESS score of≥3 for screening moderate-to-severe OSAHS and≥4 for severe OSAHS has some reference value.
