Objective:To screen the risk factors of acute kidney injury (AKI) in patients with multiple trauma, construct a prediction model accordingly, and evaluate its predictive value.Methods:A retrospective cohort study was performed to analyze the clinical data of 560 multiple trauma patients who were admitted to while Affiliated Hospital of Jiangsu University from January 2017 to June 2023, including 424 males and 136 females, aged 18-91 years [(55.5±15.0)years]. The patients were randomly divided into a training set ( n=392) and validation set ( n=168) with a ratio of 7∶3. Of all, 77 patients were combined with AKI in the training set, while 33 patients combined with AKI in the validation set. The AKI group and non-AKI group in the training set were compared in terms of gender, age, hypertension, diabetes, cause of injury, abbreviated injury scale (AIS) score of head and neck injury, AIS score of maxillofacial injury, AIS score of chest injury, AIS score of abdominal injury, AIS score of extremities and pelvic injury, AIS score of body surface injury, systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate, body temperature, red blood cell and plasma transfusion volume within 24 hours following admission, emergency surgery, mechanical ventilation, vasoactive drug therapy, Glasgow coma score (GCS) on admission, revised trauma score (RTS) on admission, acute physiology and chronic health assessment II (APACHE II) on admission, injury severity score (ISS) on admission, and laboratory test results on admission including white blood cell count, neutrophil count, lymphocyte count, C-reactive protein, hemoglobin, platelet count, activated partial thromboplastin time (APTT), prothrombin (PT), fibrinogen (FIB), thrombin time (TT), international normalized ratio (INR), D-dimer, blood lactate, base excess, total bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, globulin, urea nitrogen, serum creatinine, blood glucose, potassium, sodium and chloronium. In the training set, univariate analysis and Lasso regression analysis were used to screen the risk factors of AKI in patients with multiple trauma, which were then included into multivariate logistic regression analysis to identify the independent risk factors. A nomogram prediction model was constructed using the R software based on the above independent risk factors. Hosmer-Lemeshow (H-L) goodness-of-fit test was performed to evaluate the fitting degree of the prediction model in the training set and the validation set, and the receiver operating characteristic (ROC) curve, calibration curve and clinical decision curve (DCA) were plotted in the training set and the validation set to evaluate the predictive performance of the prediction model. Results:There were statistically significant differences in AIS score of abdominal injury, heart rate, body temperature, red blood cell and plasma transfusion volume within 24 hours following admission, emergency surgery, mechanical ventilation, vasoactive drug therapy, GCS on admission, RTS on admission, APACHE II on admission, ISS on admission as well as hemoglobin, platelet count, APTT, PT, FIB, TT, INR, blood lactate, base excess, AST, albumin, globulin, urea nitrogen, serum creatinine, blood glucose and sodium on admission between the AKI group and the non-AKI group ( P<0.05 or 0.01). The characteristic variables screened by Lasso regression analysis included AIS score of abdominal injury, red blood cell transfusion volume within 24 hours following admission, mechanical ventilation, vasoactive drugs therapy, blood lactate on admission, blood creatinine on admission, AST on admission, and blood sodium on admission. Multivariate logistic regression analysis showed that red blood cell transfusion volume within 24 hour following admission ( OR=1.09, 95% CI 1.01, 1.18), mechanical ventilation ( OR=2.49, 95% CI 1.06, 5.85), vasoactive drug therapy ( OR=2.04, 95% CI 1.03, 4.03), blood lactate on admission ( OR=1.10, 95% CI 1.01, 1.21) and serum creatinine on admission ( OR=1.02, 95% CI 1.01, 1.03) were independent risk factors for AKI in patients with multiple trauma ( P<0.05). The regression equation was constructed: Logit[ P/(1- P)]=0.086 2×"red blood cell transfusion volume within 24 hour following admission"+0.912 7×"mechanical ventilation"+0.713 2×"vasoactive drug therapy"+0.098 9×"blood lactate on admission"+0.019 2×"serum creatinine on admission" -4.822 3. H-L goodness-of-fit test showed χ2 value of 9.50 in the training set ( P>0.05) and 6.43 in the validation set ( P>0.05). The results of the ROC curve indicated that the area under the curve (AUC) was 0.84 (95% CI 0.78, 0.89) in the training set and 0.80 (95% CI 0.72, 0.88) in the validation set. The calibration curves showed good agreement with the actual curves, with the predicted probability consistent with the actual probability in both training set and validation set. DCA analysis showed that the threshold probability ranged from 2% to 70% with the net benefit rate of the prediction model greater than 0 in the training set, while the threshold probability ranged from 3% to 69% with the net benefit rate of the prediction model greater than 0 in the validation set. Conclusions:Red blood cell transfusion volume within 24 hours following admission, mechanical ventilation, vasoactive drug therapy, lactate and serum creatinine on admission are independent risk factors for AKI in patients with multiple trauma. The nomogram prediction model based on the above 5 predictive variables of AKI in patients with multiple trauma shows good predictive efficacy and clinical application value.

Objective:To investigate the targets and mechanisms of cycloastragenol in ameliorating azithromycin-induced drug-induced liver injury(DILI)based on network pharmacology and in vitro experiment validation.Methods:Potential targets of cycloastragenol and DILI were predicted using databases.The common and key targets were screened and subjected to GO and KEGG enrichment analyses,as well as molecular docking validation.Primary hepatocytes from C57BL/6 mice were isolated.The optimal concentration and time for azithromycin-induced DILI in mouse primary hepatocytes were determined using CCK8 and ROS assays.The expression of genes and proteins such as NF-κB p65,p-NF-κB p65,AMPKα,and p-AMPKα was assessed using RT-qPCR and Western blot to evaluate the intervention effect of cycloastragenol(10-50 μmol/L).Results:Network pharmacology analysis identified 10 key genes related to cycloastragenol's improvement of DILI,including heat shock protein 90AA1(HSP90AA1),matrix metalloproteinase 2(MMP2),etc.GO enrichment analysis suggested that cycloastragenol primarily regulates biological processes such as membrane potential and chemical synaptic transmission,and affects cellular components such as neuronal cell bodies and distal axons,and related kinase activities.KEGG enrichment analysis showed that it mainly exerts intervention effects through neuro-signaling pathways and IL-17 signaling pathways.Molecular docking demonstrated strong binding of cycloastragenol to HSP90AA1,MMP2,NF-κB p65,AMPKα,nuclear factor erythroid 2-related factor 2(Nrf2),heme oxygenase 1(HO-1),and NAD(P)H:quinone oxidoreductase 1(NQO1),with a binding energy≤-5.0 kcal/mol for Nrf2.In vitro experiments showed that azithromycin(50 μmol/L,12 h)significantly reduced hepatocyte viability and increased ROS levels(P＜0.01).Different concentrations of cycloastragenol significantly improved the activity of mouse primary hepatocytes,reduced the generation of intracellular ROS,downregulated the phosphorylation level of NF-κB p65,and upregulated the mRNA and protein levels of AMPKα,Nrf2,HO-1,NQO1(P＜0.05).Conclusions:Cycloastragenol may alleviate azithromycin-induced hepatocyte oxidative stress and inflammation by inhibiting NF-κB phosphorylation and activating the AMPK/Nrf2/HO-1/NQO1 pathway,with its mechanism likely closely linked to targeting Nrf2.However,the complex mechanisms of DILI may involve additional unverified pathways.Therefore,further studies are necessary to validate the efficacy and safety of cycloastragenol in animal models.

Objective To screen and verify the genes that play key role in the occurrence and development of esophageal cancer by u-sing bioinformatics and real-time fluorescence quantitative PCR(qRT-PCR)methods to find new markers for diagnosis of esophageal cancer(ESCA).Methods Using the TCGA database and Wayne plot analysis,the cross genes between the differentially expressed genes of ESCA and the genes which have the most significant impacts on disease-free survival(DFS)rate in esophageal cancer patients were preliminarily identified.Following conducting protein-protein interaction(PPI)network analysis on the overlapping genes,GO and KEGG functional analysis was performed to screen the potential key genes as the diagnostic markers of esophageal cancer.qRT-PCR was used to quantitatively analyze the expression of mRNA of the key gene in peripheral blood.Statistical analysis was con-ducted based on the clinico-pathological characteristics of the patients to determine its potential value as a new diagnostic marker for e-sophageal cancer.Results After overlapping of differentially expressed genes of ESCA and disease-free survival genes in the TCGA database,39 upregulated genes and 20 downregulated genes were found to be differentially expressed,all of which affected disease-free survival rate.After conducting PPI network analysis,15 upregulated genes with core interactions were identified,and the downregulat-ed genes did not form any interaction network.Further enrichment analysis of these 15 core interacting genes through GO and KEGG,revealed that fibronectin 1(FN1)may be a potential biomarker for ESCA diagnosis.The qRT-PCR results showed that compared with the healthy control group,the mRNA expression level of FN1 in the peripheral blood of esophageal cancer patients was significantly ele-vated.After analyzing the clinical characteristics of patients,it was found that the patients with poor differentiation and high clinico-pathological staging had significantly increased peripheral blood FN1 mRNA levels.The model with FN1 mRNA expression levels can distinguish esophageal cancer patients from healthy individuals.Conclusion FN1 mRNA may be a potential non-invasive diagnostic biomarker for esophageal cancer.

BACKGROUND:Mesenchymal stem cells possess characteristics such as rapid renewal,targeted homing,tissue repair,and immune regulation,which provide potential for the treatment of inflammatory diseases.In most inflammatory diseases,interleukin-1β is highly expressed.Both exogenous and endogenous mesenchymal stem cells unavoidably exist in an environment with high interleukin-1β concentration. OBJECTIVE:To study the interaction of interleukin-1β with mesenchymal stem cells in inflammatory environment and the mechanism of its influence on the migration and adhesion of mesenchymal stem cells to provide a theoretical basis for adjusting stem cell therapy strategies. METHODS:The first author searched for studies involving interleukin-1β enhancing migration and adhesion of mesenchymal stem cells by computer on CNKI,WanFang,VIP,PubMed,and Web of Science using search terms"interleukin-1β,mesenchymal stem cell,nuclear factor-κB,MAPK,ERK,p38,migration,adhesion"in Chinese and English.The literature tracing method was also used to search for some of the literature.Finally,65 articles were included in the review analysis. RESULTS AND CONCLUSION:(1)In the inflammatory environment,interleukin-1β can regulate the migration and adhesion ability of mesenchymal stem cells.This effect may be achieved by recruiting IRAK1 through interleukin-1RI and then activating TAK1 and IKK in turn.After IKK phosphorylation,nuclear factor-κB and ERK signaling pathways are activated or CXCR expression is upregulated through the p38 pathway to promote mesenchymal stem cell migration and adhesion.However,further standardized research needs to be carried out based on the genetic background of mesenchymal stem cells,the dose and processing time of interleukin-1β.(2)In vitro experiments using pre-stimulated mesenchymal stem cells with interleukin-1β can change the survival environment of mesenchymal stem cells and alter their secretion factors to make them develop towards a more anti-inflammatory direction.On the other hand,under the premise of producing higher levels of anti-inflammatory and pro-nutrient factors,extracted mesenchymal stem cell exosomes can exert anti-inflammatory effects.(3)It has been observed in various animal disease models that pre-stimulating mesenchymal stem cells with interleukin-1β regulates their immune regulation ability,thereby affecting the development and outcome of inflammation.However,this is limited to preclinical basic research only;further verification on efficacy and safety of stem cell therapy with interleukin-1β pre-treated mesenchymal stem cells is required in clinical settings.

ObjectiveTo evaluate the clinical effectiveness and safety of Bairui Granules （百蕊颗粒） in the treatment of acute pharyngitis with wind-heat syndrome. MethodsA multicenter， double-blind， double-simulation， randomised controlled trial was conducted， in which 162 patients with acute pharyngitis and wind-heat syndrome from 7 centers were recruited， and each center was divided into trial group and control group on the ratio of 2∶1. In the trial group， 108 cases were orally administered with Bairui Granules plus Reyanning Granules （热炎宁颗粒） simulant， and in the control group， 54 cases were orally administered with Reyanning Granules plus Bairui Granules simulant for 5 days， with a follow-up visit on the 6th day. Full analysis set （FAS） analysis and per protocol set （PPS） were used for analysis， respectively. The primary efficacy index was the disappearance rate of sore throat after 5-day treatment； the secondary efficacy indexes were the disappearance rate of sore throat after 3-day treatment， as well as the visual analogue score （VAS） of sore throat before treatment， every day during the treatment， and follow-up on day 6， and the traditional Chinese medicine （TCM） syndrome score was performed before treatment and at the follow-up on day 6. The effectiveness on TCM syndrome was evaluated at the follow-up on day 6， and the changes of vital signs， blood routine， urine routine， liver functions， kidney function， the adverse events before and after the treatment were recorded， and safety analysis set （SS） was analysed. Results162 patients entered the FAS and SS analyses， and 158 cases （105 cases in the trial group and 53 cases in the control group） entered the PPS analysis. FAS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.56% （87/108） in the trial group and 64.81% （35/54） in the control group， and the difference between groups was statistically significant （χ² = 5.10， P = 0.0239）. PPS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.00% （84/105） in the trial group and 64.15% （34/53） in the control group， and the difference between groups was statistically significant （χ² =4.85， P = 0.0277）. FAS and SS analyses both showed that the difference in disappearance rate of sore throat between groups on 3-day treatment was not statistically significant （P＞0.05）. Compared with those before treatment， the VAS scores of sore throat were lower in both groups during treatment on day 2， 3， 4， 5， and follow-up on day 6 （P＜0.01）， but the difference between groups at each time point was not statistically significant （P＞0.05）. TCM syndrome scores of both groups at the follow-up were lower than that before treatment， and those of the trial group were lower than those of the control group （P＜0.01）. The cure rate and effective rate of TCM syndrome of the trial group were significantly higher than those of the control group （P＜0.01）. There was no significant difference in blood routine， urine routine， liver function， kidney function between groups before and after treatment （P＞0.05）， and no serious adverse events occured in both groups. ConclusionBairui Granules showed clinical effectiveness in the treatment of acute pharyngitis of wind-heat syndrome， and it could significantly improve the clinical symptoms， accelerate the disappearance time of sore throat with good safety.

Objective:To investigate the safety and effectiveness of tension adjustment technique using anatomical landmarks during retropubic midurethral synthetic sling.Methods:The data of 36 consecutive female patients with urinary incontinence, who had underwent retropubic midurethral synthetic sling procedure from January to August 2019 were analyzed retrospectively. The mean age was (60.83±7.93) years old and the body mass index was (24.43±2.44) kg/m 2. Among the recruited subjects, 36 had positive stress test and Marshall-Marchetti test. 20 (55.6%) were pure stress urinary incontinence, and 16 (44.4%) were mixed urinary incontinence. The severity of incontinence was classified into mild (5 cases, 13.9%), moderate (14 cases, 38.9%), severe (13 cases, 36.1%) and very severe (4 cases, 11.1%) using one-hour pad tests. Urodynamics were performed in 17 cases, with 5 (29.4%) presented detrusor overactivity, 3 (17.7%) possessed intrinsic sphincter deficiency. For each case, the tension of the sling was adjusted based on the anatomical landmarks, i. e. using an angled clamp attached closely to the pubic symphysis ventrally and the tip parallel to the edge of hymen dorsally. All patients were catheter-free right after the procedure. The subjective and objective effectiveness, and safety (the rate of urinary retension after surgery and postvoid residual volume 3 months later) were evaluated.The subjective cure rate was was defined as complete leakage free or very mild leakage during excessive bladder filling and fierce cough. The subjective effectiveness was defined as over 50% improvement of the leakage symptom. The objective cure rate was defined as a negative stress test. Results:For all 36 patients, the median hospital stays was 8 (5-95)h. No bladder perforation or transfusion cases. All patients were catheter-free right after the procedure, with no incidence of urinary retention. 27 patients completed a 3-month follow-up, with 22 had post-void residual data, 23 had subjective effectiveness data and 23 had objective effectiveness data. The median post-void residual was 7.5 (5-64) ml, subjective cure rate was 91.3% (21/23), and objective cure rate was 95.7% (22/23). 8.7% (2/23) reported difficult urination alleviated without the necessity of clinical interference. No urethra erosion or vagina extrusion was found. At 2-year follow-up, 34 patients completed assessment by phone. The subjective cure rate was 91.2% (31/34), with only 2.9% (1/34) reported difficult urination. Besides, at 3-month follow-up, there was no difference regarding the subjective cure rate [100.0%(12/12) vs. 81.8%(9/11)]or objective cure rate [91.7%(11/12) vs. 100.0%(11/11)] between patients with stress and mixed incontinence. No difference was noted among patients with mild, moderate, severe and very severe leakage[75.0% (3/4) vs. 100.0%(6/6) vs. 90.0%(9/10) vs. 100.0%(3/3)]. Of the 12 cases with urodynamic records, the presence of detrusor overactivity [66.7%(2/3) vs. 88.9%(8/9)] or intrinsic sphincter deficiency [0(0/1) vs. 90.9%(10/11)] did not significantly affected the cure rate of the procedure. At 2-year follow-up, there was no difference regarding the subjective cure rate between patients with stress and mixed incontinence [94.7%(18/19) vs. 86.7%(13/15)]. No difference was also noted among patients with mild, moderate, severe and very severe leakage[80.0%(4/5) vs. 100.0%(13/13) vs. 83.3%(10/12) vs. 100.0%(4/4)]. Of the 16 cases with urodynamic records, the presence of detrusor overactivity [60.0%(3/5) vs. 90.9%(10/11)]or intrinsic sphincter deficiency [66.7%(2/3) vs. 84.6%(11/13)]did not significantly affected the cure rate of the procedure.Conclusions:Tension adjustment using anatomic landmarks during sling procedure is safe and feasible for urinary incontinence, with minimum complications and residual volume, and high subjective/objective cure rate.

Objective : To investigate the expression levels and potential clinical significance of pre-B-cell leukemia homologous box 3 (PBX3) in bone marrow samples from acute myeloid leukemia (AML) . Methods : The mRNA expression levels of PBX3 were determined by bioinformatics which analyzed the RNAseq data of 33 malignancies from the cancer genome atlasdatabase． (TCGA) The correlations among the expression levels of PBX3，the clinical parameters and prognosis of AML patients were further analyzed．The differentially expressed genes in the whole transcriptome were analyzed to identify the molecular network in AML caused by PBX3 expression abnormalities. Results : The mRNA expression levels of PBX3 were up-regulated in 12 malignancies，and the altitudes increased most significantly in AML than any other cancer types．Patients with high PBX3 expression showed shorter overall survival and disease-free survival than patients with low PBX3 expression．High PBX3 expression was significantly associated with FLT3，NPM1，and DNMT3A mutation．PBX3 expression was positively correlated with multiple ho- meobox genes (including most HOXA and HOXB genes ，MEIS1 ) ，and the expression levels of these homeobox genes were all negatively correlated with AML patients overall survival． Conclusion PBX3 high expression in the bone marrow of AML patients is a potential biomarker for poor prognosis ，and it may have extensive interactions with other homeobox genes.
