ObjectiveThe controllability changes of structural brain network were explored based on the control and brain network theory in young smokers, this may reveal that the controllability indicators can serve as a powerful factor to predict the sleep status in young smokers. MethodsFifty young smokers and 51 healthy controls from Inner Mongolia University of Science and Technology were enrolled. Diffusion tensor imaging (DTI) was used to construct structural brain network based on fractional anisotropy (FA) weight matrix. According to the control and brain network theory, the average controllability and the modal controllability were calculated. Two-sample t-test was used to compare the differences between the groups and Pearson correlation analysis to examine the correlation between significant average controllability and modal controllability with Fagerström Test of Nicotine Dependence (FTND) in young smokers. The nodes with the controllability score in the top 10% were selected as the super-controllers. Finally, we used BP neural network to predict the Pittsburgh Sleep Quality Index (PSQI) in young smokers. ResultsThe average controllability of dorsolateral superior frontal gyrus, supplementary motor area, lenticular nucleus putamen, and lenticular nucleus pallidum, and the modal controllability of orbital inferior frontal gyrus, supplementary motor area, gyrus rectus, and posterior cingulate gyrus in the young smokers’ group, were all significantly different from those of the healthy controls group (P<0.05). The average controllability of the right supplementary motor area (SMA.R) in the young smokers group was positively correlated with FTND (r=0.393 0, P=0.004 8), while modal controllability was negatively correlated with FTND (r=-0.330 1, P=0.019 2). ConclusionThe controllability of structural brain network in young smokers is abnormal. which may serve as an indicator to predict sleep condition. It may provide the imaging evidence for evaluating the cognitive function impairment in young smokers.

Stasis-heat is a pathological factor associated with numerous exogenous and internal injuries, representing a pivotal mechanism in disease progression. Its primary cause is fire-heat toxicity. Based on the theory of qi and the holistic perspective of traditional Chinese medicine, this concept emphasizes that the biochemistry of all natural phenomena relies on the dynamic movement of qi ascending, descending, exiting, and entering. Within six qi, "fire" includes sovereign and ministerial fires. While physiological ministerial fire is the source power of life, pathological ministerial fire manifests as violent, intense energy that readily interacts with blood, leading to the formation of stasis-heat. Therefore, this article examines the formation and treatment of stasis-heat resulting from ministerial fire dysfunction. From the perspectives of ministerial fire gasification, the shape and quality of meridians, and the elevation of ministerial fire, it elucidates why the "pericardium-sanjiao-gallbladder" axis is regarded as pivotal. Furthermore, when the "pericardium-sanjiao-gallbladder" ministerial fire axis is unfavorable, and the stagnation of ministerial fire elevation and blockage is crucial to stasis-heat formation. Additionally, the depletion of essence and blood in the liver and kidneys, preventing the proper storage of ministerial fire, forms the pathological foundation. Drawing upon The Inner Canon of Yellow Emperor, this article explores therapeutic principles based on the rules of odor treatment: "when fires in the interior, the treatment of salty and cold, accompanied by bitter and pungent, acid to astringe, bitter to disperse." These principles are applied to achieve specific therapeutic goals: tempering the excess of ministerial fire to cool the nutritive level and transform stasis; adjusting the imbalance of elevation and depression to vent heat and unblock stasis; and restoring the misplaced fire by nourishing blood to expel stasis. Through these approaches, the article aims to reestablish the proper circulation of ministerial fire, dissipate blood stasis, and ultimately eliminate stasis-heat, thereby offering an integrated perspective on its pathogenesis and treatment.

Objective To explore the value of combined ultrasound parameters, including the hepatorenal index (HRI) and renal resistance index (RRI), with cystatin C (CysC) in monitoring early acute kidney injury (AKI) after liver transplantation. Methods Perioperative data from 121 liver transplant recipients who received organs from donation after brain death were collected. The HRI and RRI of the recipients were measured on postoperative days 1-7 and at 1 month, and the CysC levels were measured on postoperative day 1. The recipients were divided into the AKI group (n=53) and the non-AKI group (n=68) based on whether AKI occurred within 7 days after operation. The data of the two groups were compared, and the ultrasound parameters before and after recovery in the AKI group were analyzed. The value of combined HRI, RRI and CysC in monitoring AKI was also analyzed. Results AKI occurred in 53 recipients, with an incidence rate of 43.8%, including 30 cases of stage 1, 18 cases of stage 2, and 5 cases of stage 3. Among them, 49 cases occurred on postoperative day 1, and 4 cases occurred on postoperative day 2. Of these, 43 cases recovered within 7 days after surgery, 8 cases recovered within 2 months after surgery, 1 case was lost to follow-up, and 1 case received renal replacement therapy. The body mass index and preoperative CysC levels were higher in the AKI group than in the non-AKI group, and the operative time was longer in the AKI group than in the non-AKI group (all P < 0.05). The HRI on postoperative day 1 was lower in the AKI group than in the non-AKI group, while the RRI and CysC levels were higher (all P < 0.05). When AKI occurred, the HRI was lower than the baseline level, and the RRI was higher than the baseline level. As AKI recovered, the HRI gradually increased, and the RRI gradually decreased. The receiver operating characteristic curve analysis showed that the sensitivity and specificity of HRI ≤ 1.12 for predicting AKI were 0.623 and 0.878, respectively, with an area under the curve (AUC) of 0.801. The sensitivity and specificity of RRI ≥ 0.65 for predicting AKI were 0.878 and 0.676, respectively, with an AUC of 0.825. The sensitivity and specificity of CysC ≥ 1.38 mg/L for predicting AKI were 0.736 and 0.882, respectively, with an AUC of 0.851 (all P<0.01). The combination of HRI and CysC (AUC=0.897, P<0.01), RRI and CysC (AUC=0.910, P<0.01), and all three parameters combined (AUC=0.934, P<0.01) were more effective than using each parameter alone. Conclusions HRI and RRI may be used to monitor the occurrence and recovery of early AKI after liver transplantation. The combination of these two parameters with CysC has a high application value in monitoring early AKI after liver transplantation.

Objective To investigate the impact of continuous nebulization therapy after lung transplantation on pulmonary function and related complications in lung transplant recipients. Methods A retrospective analysis was conducted on the general data of 71 recipients who underwent allogeneic lung transplantation at the Department of Thoracic Surgery, the First Affiliated Hospital of Zhengzhou University, from June 2013 to December 2024. Recipients were divided into observation group (those who continued nebulization therapy for more than 3 months after discharge) and control group (those who discontinued nebulization therapy on their own). The main observation indicators were pulmonary function indicators at 6 months after surgery, including forced expiratory volume in the first second as a percentage of predicted value (FEV1% pred), forced vital capacity as a percentage of predicted value (FVC% pred), ratio of forced expiratory volume in the first second to forced vital capacity as a percentage of predicted value (FEV1/FVC% pred), forced expiratory flow at 25%, 50% and 75% of forced vital capacity as a percentage of predicted value, and the percentage of predicted value of corrected carbon monoxide diffusion capacity measured by single-breath method, as well as the ratio of corrected carbon monoxide diffusion capacity to alveolar volume as a percentage of predicted value. Additionally, the annual incidence of postoperative pulmonary infections, survival rate and the rate of no severe airway complications were analyzed. Results At 6 months after lung transplantation, the FEV1% pred and FVC% pred of the observation group were better than those of the control group [FEV1% pred was 76% (60%, 91%) vs. 67% (62%, 78%), FVC% pred was (75 ± 13)% vs. (69 ± 11)%, both P<0.05]. The observation group had a lower annual incidence of pulmonary infections compared to the control group (P = 0.023), with a risk of 0.485 times that of the control group. There were no statistically significant differences between the two groups in median survival time and the rate of no severe airway complications (both P>0.05). Conclusions Continuous nebulization therapy after lung transplantation may effectively improve pulmonary function, reduce the annual incidence of pulmonary infections, and play a positive role in the long-term maintenance of pulmonary function.

As a common neurological disease in China, stroke has an extremely high rate of death and disability, of which 80% is ischemic stroke (IS), causing a serious burden to individuals and society. Neuronal death is an important factor in the pathogenesis of stroke. Studies have shown that mitochondrial dynamics, as a key mechanism regulating intracellular energy metabolism and cell death, plays an important role in the pathogenesis of IS. In recent years, targeting mitochondrial dynamics has become an emerging therapeutic tool to improve neurological impairment after stroke. This paper reviews the research advance in recent years in IS mitochondrial dynamics, summarizing and discussing the overview of mitochondrial dynamics, the role of mitochondrial dynamics in IS, and the studies on mitochondrial dynamics-based treatment of IS. This paper helps to explore the mechanism of the role of mitochondrial dynamics in IS and effective interventions, and provides a theoretical strategy for targeting mitochondrial dynamics to treat IS in the clinic.

ObjectiveTo investigate the application value of a multimodal model integrating radiomics features, deep learning features, and clinical structured data in predicting severe acute pancreatitis (SAP), and to provide more accurate tools for the early identification of SAP in clinical practice. MethodsThe patients with acute pancreatitis (AP) who attended The First Affiliated Hospital of Soochow University, Jintan Hospital Affiliated to Jiangsu University, and Suzhou Yongding Hospital from January 1, 2017 to December 31, 2023 were included. Related data were collected, including demographic information, previous medical history, etiology, laboratory test data, and systemic inflammatory response syndrome (SIRS) within 24 hours after admission, as well as imaging data within 72 hours after admission, while related scores were calculated, including Ranson score, modified CT severity index (MCTSI), bedside index for severity in acute pancreatitis (BISAP), and systemic inflammatory response syndrome, albumin, blood urea nitrogen and pleural effusion (SABP) score. The model was constructed in the following process: (1) three-dimensional CT images were used to extract and identify radiomics features, and a radiomics classification model was established based on the extreme gradient Boost (XGBoost) algorithm; (2) U-Net is used to perform semantic segmentation of three-dimensional CT images, and then the results of segmentation were imported into 3D ResNet50 to construct a deep learning classification model; (3) the predicted values of the above two models were integrated with clinical structured data to establish a multimodal model based on the XGBoost algorithm. The variable importance plot and local interpretability plot were used to perform visual interpretation of the model. The independent samples t-test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test or Fisher’s exact test was used for comparison of categorical data between groups. The receiver operating characteristic (ROC) curve was plotted for each model and existing scoring systems, and the area under the ROC curve (AUC) was calculated to assess their performance; the Delong test was used for comparison of AUC. ResultsA total of 609 patients who met the criteria were included, among whom 114 (18.7%) developed SAP. In this study, the data of 426 patients from The First Affiliated Hospital of Soochow University was used as the training set, and the data of 183 patients from Jintan Hospital Affiliated to Jiangsu University and Suzhou Yongding Hospital were used as the independent test set. The multimodal model had an AUC of 0.914 in the test set, which was significantly higher than the AUC of traditional scoring systems such as MCTSI (AUC=0.827), Ranson score (AUC=0.675), BISAP (AUC=0.791), and SABP score (AUC=0.648); in addition, the multimodal model showed a significant improvement in performance compared with the radiomics classification model (AUC=0.739) and the deep learning classification model (AUC=0.685) (the Delong test: Z=-3.23, -4.83, -3.48, -4.92, -4.31, and -4.59, all P <0.01). The top 10 variables in terms of importance in the multimodal model were pleural effusion, predicted value of the deep learning model, predicted value of the radiomics model, triglycerides, calcium ions, SIRS, white blood cell count, age, platelets, and C-reactive protein, suggesting that the above variables had significant contributions to the performance of the model in predicting SAP. ConclusionBased on structured data, radiomic features, and deep learning features, this study constructs a multicenter prediction model for SAP based on the XGBoost algorithm, which has a better predictive performance than existing traditional scoring systems and unimodal models.

ObjectiveTo observe the effect of earthworm protein on the expression of phosphatidylinositol 3-kinase/protein kinase B/nuclear factor E2-related factor 2 (PI3K/Akt/Nrf2) pathway in the aorta of spontaneously hypertensive rats (SHR) and explore mechanism of earthworm protein in treating hypertensive vascular endothelial dysfunction (VED). MethodTen 10-week-old Wistar Kyoto (WKY) rats and fifty SHR rats were selected for a week of adaptive feeding. WKY rats were selected as the normal group, and fifty SHR rats were randomized according to body weight into model, valsartan (8×10-3 g·kg-1·d-1), and high-, medium-, and low-dose (0.2, 0.1, 0.05 g·kg-1·d-1, respectively) earthworm protein groups. The normal and model groups were administrated with equal volume of double distilled water by gavage. During the drug intervention period, the general situations of rats in each group were observed and their blood pressure was monitored at specific time points every other week before and after administration. After 8 weeks of drug intervention, enzyme-linked immunosorbent assay was employed to measure the levels of angiotensin-Ⅱ (Ang-Ⅱ) and endothelin-1 (ET-1) in the serum of rats in each group. The corresponding kits were used to determine the levels of nitric oxide (NO), malondialdehyde (MDA), glutathione peroxidase (GPX), superoxide dismutase (SOD), and ferrous ion (Fe2+). Hematoxylin-eosin (HE) staining was employed to observe the changes in the intima of the aorta. Fluorescence quantitative polymerase chain reaction (Real-time PCR) was employed to measure the mRNA levels of PI3K, Akt, Nrf2, heme oxygenase-1 (HO-1), and glutathione peroxidase 4 (GPX4) in the aortic tissue. Western blotting was used to determine the protein levels of p-PI3K (Tyr467/199), PI3K, p-Akt (Ser473), Akt, Nrf2, HO-1, and GPX4 in the thoracic aorta. ResultCompared with the normal group, the model group had decreased body mass, increased irritability, severe endothelial damage, elevated blood pressure and serum levels of Ang-Ⅱ, ET1, MDA, and Fe2+ (P<0.01), lowered NO level (P<0.01), and down-regulated mRNA and protein levels of p-PI3K (Tyr467/199), PI3K, p-Akt (Ser473), Akt, Nrf2, HO-1, and GPX4 in the aortic tissue (P<0.01). Compared with the model group, drug intervention caused no significant change in the body mass, calmed the rats, alleviated the endothelial damage, lowered blood pressure and serum levels of Ang-Ⅱ, ET1, MDA, and Fe2+ (P<0.01), elevated the NO level (P<0.05), and up-regulated the mRNA and protein levels of p-PI3K (Tyr467/199), PI3K, p-Akt (Ser473), Akt, Nrf2, HO-1, and GPX4 (P<0.05). ConclusionThe earthworm protein can exert antihypertensive effects by ameliorating VED in SHR. Specifically, it may regulate the PI3K/Akt/Nrf2 signaling pathway to inhibit oxidative stress and ferroptosis.

Objective:To analyze the association between healthy lifestyle and mortality among Henan Province 35-74 years old individuals.Methods:Data from the programme of screening and intervention subjects with high-risk cardiovascular disease 99 133 adults were analyzed in a provincial cohort study of 16 counties. Four healthy lifestyle behaviors were assessed based on a questionnaire survey. Information on mortality endpoints was retrieved from the national death surveillance system. Cox proportional hazards regression models were used to estimate the associations between healthy lifestyles, mortality risk and population attributable fraction (PAF).Results:Out of the adult participants in Henan, 50.6% adhered to a healthy lifestyle, and only 0.1% adhered to 4 healthy lifestyle behaviours. During a mean of 4.5 years, 2 685 all-cause death and 1 283 cardiovascular deaths were documented. The decreased risk of mortality among individuals with non-smoking, moderate drinking, adequate exercise and healthy diet were 0.85 (95% CI: 0.77-0.94), 0.75 (95% CI: 0.63-0.89), 0.73 (95% CI: 0.67-0.79) and 0.86 (95% CI: 0.77-0.96), while the adjusted PAF for all-cause deaths were 5.2% (95% CI: 2.5%-7.9%), 24.0% (95% CI: 10.7%-36.4%), 19.4% (95% CI: 13.8%-24.8%) and 12.3% (95% CI: 3.4%-20.9%), respectively. A combined healthy lifestyle can bring more health benefits. Adherence to 4 healthy lifestyle behaviours could avoid 49.1% of all-cause death. Conclusion:Adherence to a healthy lifestyle can reduce the risk of death, and participants with a healthy lifestyle had a lower mortality risk.

Objective:To explore the surgical technique and results of three-dimensional aortic valve anatomic repair for bicuspid aortic valve (BAV) with aortic regurgitation (AR).Methods:This is a retrospective case series study. From August 2021 to December 2023, 130 consecutive patients with BAV-AR underwent aortic valve anatomic repair at the Department of Cardiothoracic Surgery, Zhongshan Hospital, Fudan University,and the data were retrospectively analyzed. There were 115 males and 15 females, aged (38.6±11.7) years (range: 15 to 67 years). All patients received modified aortic root reconstruction, to do three-dimensional root remodeling, including the basal ring, sinus of Valsalva and sino-tubular junction simultaneously. Perioperative and follow-up data were collected and analyzed. Comparisons between groups were performed using independent samples t-test, Wilcoxon paired signed-rank test, or χ2 test. Results:No patient transferred to valve replacement during the operation. The cardiopulmonary bypass time ( M(IQR)) was 109(34) minutes (range:67 to 247 minutes), and the aortic cross-clamp time was 76(26) minutes (range: 32 to 158 minutes). Preoperative transesophageal echocardiography showed 123 patients (94.6%) presented with moderate or severe regurgitation. Immediately postoperative transesophageal echocardiography showed no regurgitation in 22 patients (16.9%), trace regurgitation in 81 patients (62.3%) and mild regurgitation in 27 patients (20.8%). Follow up was completed in all patients, with a follow-up of 5.5(9.4) months (range: 0.1 to 27.6 months). No mortality was observed during follow-up. Echocardiography was obtained in 112 patients at the latest follow-up, including no regurgitation in 4 patients (3.6%), trace regurgitation in 58 patients (51.8%), mild regurgitation in 45 patients (40.2%), moderate regurgitation in 4 patients (3.6%), and severe regurgitation in 1 patient (0.9%). Conclusion:For patients with BAV-AR who have good valve quality and no severe aortic sinus dilation, the recent outcomes of three-dimensional anatomical repair technique, focusing on overall remodeling of the aortic root, are satisfactory.
