OBJECTIVE: To explore the feasibility of incorporating simple bedside indicators into death predictive model for elderly critically ill patients based on interpretability machine learning algorithms, providing a new scheme for clinical disease assessment. METHODS: Elderly critically ill patients aged ≥ 65 years who were hospitalized in the intensive care unit (ICU) of Tacheng People's Hospital of Ili Kazak Autonomous Prefecture from June 2017 to May 2020 were retrospectively selected. Basic parameters including demographic characteristics, basic vital signs and fluid intake and output within 24 hours after admission, as well acute physiology and chronic health evaluation II (APACHE II), Glasgow coma score (GCS) and sequential organ failure assessment (SOFA) were also collected. According to outcomes in hospital, patients were divided into survival group and death group. Four datasets were constructed respectively, namely baseline dataset (B), including age, body temperature, heart rate, pulse oxygen saturation, respiratory rate, mean arterial pressure, urine output volume, infusion volume, and crystal solution volume; B+APACHE II dataset (BA), B+GCS dataset (BG), and B+SOFA dataset (BS). Then three machine learning algorithms, Logistic regression (LR), extreme gradient boosting (XGboost) and gradient boosting decision tree (GBDT) were used to develop the corresponding mortality predictive models within four datasets. The feature importance histogram of each prediction model was drawn by SHapley additive explanation (SHAP) method. The area under curve (AUC), accuracy and F1 score of each model were compared to determine the optimal prediction model and then illuminate the nomogram. RESULTS: A total of 392 patients were collected, including 341 in the survival group and 51 in the death group. There were statistically significant differences in heart rate, pulse oxygen saturation, mean arterial pressure, infusion volume, crystal solution volume, and etiological distribution between the two groups. The top three causes of death were shock, cerebral hemorrhage, and chronic obstructive pulmonary disease. Among the 12 prognostic models trained by three machine learning algorithms, overall performance of prognostic models based on B dataset was behind, whereas the LR model trained by BA dataset achieved the best performance than others with AUC of 0.767 [95% confidence interval (95%CI) was 0.692-0.836], accuracy of 0.875 (95%CI was 0.837-0.903) and F1 score of 0.190. The top 3 variables in this model were crystal solution volume with first 24 hours, heart rate and mean arterial pressure. The nomogram of the model showed that the total score between 150 and 230 were advisable. CONCLUSION The interpretable machine learning model including simple bedside parameters combined with APACHE II score could effectively identify the risk of death in elderly patients with critically illness.

Objective:To analyze the prognostic outcomes of 1 147 patients who underwent liver transplantation at Qingdao University Affiliated Hospital and to summarize measures to enhance the efficacy of liver transplantation.Methods:A retrospective analysis was conducted on the clinical and follow-up data of 1 147 liver transplant patients at Qingdao University Affiliated Hospital.Results:The overall postoperative 1-, 3-, and 5-year survival rates for the 1 147 liver transplant patients were 87.20%, 73.40%, and 65.60%, respectively. The survival rates for benign disease liver transplant recipients were 88.01%, 84.98%, and 81.39% at 1, 3, and 5 years post-transplant, respectively, compared to recipients transplanted for malignancies of 78.11%, 64.41%, and 60.06% (all P<0.001). Among the mid vs more recent period, patients' 1-year and 3-year postoperative survival rates were 84.20%, 70.80% vs 90.50%, 71.70%, respectively,significantly in favor of recently enrolled patients ( P=0.022). In the complex surgery group, patients' 1-, 3-, and 5-year survival rates were 82.70%, 65.50%, 56.70%, while in less complicated group, it was 89.00%, 76.50%, 69.20% ( P<0.001). The primary causes of death for benign disease recipients were multi-organ failure (4.1%), while in recipients with malignant disease primary cause of death was tumor recurrence (23.7%). Postoperative complications included primary graft dysfunction, delayed graft function recovery, portal vein thrombosis, hepatic artery thrombosis, biliary stricture, post-transplant lymphoproliferative disorder, and graft-versus-host disease, with occurrence rates of 1.05%, 6.89%, 1.92%, 0.44%, 2.00%, 0.61%, and 0.44%, respectively. Conclusions:With the continuous improvement in surgical techniques and perioperative care levels, the 3-year survival rate of recipients at our center has increased. Malignant diseases and complex liver transplantation remain crucial factors affecting recipient prognosis, highlighting the need to further enhance comprehensive treatment capabilities for patients with malignant diseases and complex surgeries.

Acute myocardial infarction(AMI)is a common cardiovascular emergency in clinic.Early reperfusion is a typical and effective method for the treatment of AMI.However,the recovery of blood supply after reperfusion therapy will accelerate the damage of ischemic myocardium and cause myocardial ischemia-reperfusion injury(MI/RI).In recent years,studies have found that TCM has the unique advantages of multi-component,multi-channel and multi-target in the intervention of MI/RI.Janus tyrosine kinase/signal transducer and activator of transcription(JAK/STAT)signaling pathway is closely related to MI/RI,which can reduce MI/RI process by regulating inflammation,oxidative stress,cell proliferation,differentiation and apoptosis.This article reviewed the mechanism of JAK/STAT signaling pathway in MI/RI and the research of TCM targeting this pathway,in order to provide references for the prevention and treatment of MI/RI and further drug development.

AIM:To explore the potential targets and mechanisms of Angelica sinensis and Astraga-lus membranaceus ultrafiltration(RAS-AM)in the treatment of radiation induced myocardial fibrosis(RIMF)through network pharmacology combined experimental validation.METHODS:Using the TC-MSP database TCM@TAIWAN The Taiwan Tradition-al Chinese Medicine Database and TCMID Tradition-al Chinese Medicine Database screen the compo-nents and targets of RAS-AM,and use the Swiss Target Prediction database for target prediction.Obtain RIMF disease targets from Gene Cards and OMIM databases,obtain intersection targets of dis-eases and drugs through Wayne's online tool,ob-tain protein interaction relationships(PPIs)through STRING database,and use Cytoscape 3.9.1 soft-ware to construct a visualized network topology di-agram of"drug component target disease".Con-duct GO and KEGG enrichment analysis on core tar-gets through the David database,and use the mi-crobiome platform for mapping.Experimental veri-fication:Sixty Wistar rats were randomly divided in-to a blank group,a model group,a positive drug group,a RAS-AM low-dose group,a RAS-AM medi-um dose group,and a RAS-AM high-dose group.A RIMF model was established using a 38Gy dose of radiation induction,and was administered orally for 4 weeks.The general condition of the rats was also observed.After blood and heart collection in rats,HE staining was used to observe the morpho-logical changes of myocardial tissue,and ELISA and Western blot methods were used to detect key tar-gets for network pharmacology prediction.RE-SULTS:Network pharmacology analysis revealed 34 active components and 705 targets of Angelica si-nensis and Astragalus membranaceus ultrafiltra-tion,with a total of 154 targets,with IL-6,VEGFA,MMP2,MMP9,and ACE as the top five core tar-gets;GO enrichment analysis screened a total of 153 entries,and KEGG enrichment had 25 path-ways.Experimental part:HE staining results showed that the degeneration and necrosis of myo-cardial cells improved in each medication group,the infiltration of inflammatory cells in the myocar-dial interstitium decreased,and the proliferation of fibrous connective tissue in the myocardial intersti-tium decreased.ELISA and Western blot results showed that compared with the normal group,the expression of IL-6,VEGFA,and MMP-9 in the mod-el group increased.Compared with the model groupthe expression of IL-6,VEGFA,and MMP-9 in each medication group decreased to varying de-grees,in a dose-dependent manner.CONCLUSION:RAS-AM may inhibit RIMF by downregulating core targets such as IL-6,VEGFA protein,MMP-9 pro-tein,and regulating inflammatory pathways,colla-gen degradation,and other processes.
