Endovascular therapy (EVT) is the standard treatment for acute ischemic stroke (AIS) due to large vessel occlusion (LVO), which can effectively improve patient outcome by timely restoring cerebral blood flow perfusion. The benefits of EVT are time-dependent and significant when initiated within 6 hours of onset. The onset-to-puncture time (OPT) is divided into onset-to-door time (ODT) and door-to-puncture time (DPT). ODT is the time from symptom onset to arrival at the emergency department, reflecting the efficiency of prehospital emergency treatment; DPT is the time from emergency admission to completion of femoral artery puncture, reflecting the efficiency of in-hospital diagnosis and treatment. Despite various efforts were made in the early stage to enable 41.6% of patients with AIS who received EVT achieved a door-to-device time (DDT) of <120 min, OPT is still not ideal, and issues such as inaccurate prehospital assessments and delayed in-hospital diagnosis and treatment remain severe. This article elaborates on the impact and possible mechanisms of OPT on the outcome of patients with AIS undergoing EVT, and discusses the influencing factors and optimization strategies of OPT.

[Purpose]To analyze the incidence and mortality of oral and pharyngeal cancer in can-cer registration areas of Hunan Province in 2021 and the trend changes from 2012 to 2021.[Methods]Data on oral and pharyngeal cancer incidence and mortality from 2012 to 2021 were collected from 78 quality-controlled cancer registries in Hunan Province,with population data sourced from household registration statistics provided by public security authorities.Indicators such as crude incidence and mortality rates,age-standardized incidence and mortality rates by Chinese standard population(ASIRC/ASMRC),and world standard population(ASIRW,ASMRW)in 2021 were calculated.The Chinese standard population(2000 national census)and Segi's world standard population were used for standardization.Joinpoint Regression Program 4.9.0.0 software was used to fit a Log-linear regression model,and the average annual percentage change(AAPC)of ASIRC/ASMRC of oral and pharyngeal cancer from 2012 to 2021 was calculated to analyze the changing trends.[Results]In 2021,the crude incidence rate of oral and pharyngeal cancer in cancer registration areas of Hunan Province was 9.28/105(15.14/105 for males and 3.07/105 for fe-males),with an ASIRC of 6.10/105;the crude mortality rate was 3.75/105(6.19/105 for males and 1.16/105 for females),with an ASMRC of 2.16/105.Both the incidence and mortality rates in male were significantly higher than those in female.Age distribution analysis showed that the incidence rate of oral and pharyngeal cancer increased with age after 30 years old,peaking in the age group of 60～64 years old(22.29/105);the mortality rate continued to rise after 35 years old,reaching the peak in the population aged ≥85 years old(14.52/105).Trend analysis from 2012 to 2021 indicated that the crude incidence rate and ASIRC of oral and pharyngeal cancer increased from 3.50/105 and 2.63/105 in 2012 to 9.28/105 and 6.10/105 in 2021,with AAPC of 12.33％and 10.80％,re-spectively;the crude mortality rate and ASMRC also showed upward trends(AAPC of 9.87％and 7.21％,respectively);all trend changes were statistically significant(all P＜0.05).Sex stratification revealed that the AAPC of ASIRC and ASMRC of oral and pharyngeal cancer in male were higher than those in female(AAPC of ASIRC:12.65％for males vs 4.28％for females;AAPC of ASMRC:8.79％for males vs 4.13％for females).Age-specific trend analysis found that the ASIRC of oral and pharyngeal cancer in the population aged ≤ 44 years old showed an upward trend(AAPC=11.73％,P＜0.001),with the AAPC of male in this group reaching 14.57％;the AAPC of ASIRC for the age groups of 45～64 years old and ≥65 years old were 11.03％and 9.74％,respectively,and the AAPC of ASMRC for these two groups were 10.05％and 8.19％,respectively,with all trend changes being statistically significant(all P＜0.05);there was no statistically significant change in the ASMRC of the population aged ≤44 years old(AAPC=5.66％,P=0.087).[Conclusion]The incidence and mortality rates of oral and pharyngeal cancer in cancer registration areas of Hunan Province remain high and show an upward trend,with a tendency of younger onset.Males and middle-aged and elderly populations are the key focuses of prevention and control.

Objective To investigate dynamic changes in myocardial protein phosphorylation during the acute phase of myocardial infarction (MI) in mice. Methods Six 8-week-old C57BL/6J mice were randomly assigned to MI model (n＝3) or sham-operated control (n＝3) groups. Cardiac tissues were harvested 72 hours post-intervention for proteomic analysis. Phosphorylation modifications were systematically characterized using liquid chromatography-mass spectrometry (LC-MS). Bioinformatics analyses included differential phosphorylation screening, functional enrichment, hierarchical clustering, and protein-protein interaction network. Results LC-MS identified 1 921 differentially phosphorylated sites (20 tyrosine and 1 901 serine/threonine sites) across 851 proteins. Compared with controls, MI hearts exhibited significant phosphorylation upregulation at 1 545 sites and downregulation at 376 sites (P＜0.05). Conclusions This study delineates MI-associated phosphorylation dynamics, providing mechanistic insights and potential therapeutic targets for acute MI intervention.

Objective:To investigate the level of urinary serine protease(Corin) in early diabetic kidney disease(DKD) and its correlation with clinical stage.Methods:One hundred and seventy-three patients with type 2 diabetes mellitus(DM) from two tertiary A hospitals in Henan, diagnosed between April 2023 and December 2023 were selected as the research group, and 120 healthy subjects were selected as the control group. Basic clinical information and laboratory data were collected, and urinary Corin level was detected. DM patients were classified into G1-G5 stages based on estimated glomerular filtration rate(eGFR), and those in the early DKD stages(G1-G3) were further divided into A1-A3 subgroups based on urinary albumin/creatinine ratio(ACR). Spearman correlation analysis was performed to assess relationships between urinary Corin and other indicators, linear regression analysis identified factors influencing urinary Corin in early DKD patients, logistic regression analysis evaluated the risk factors for early DKD, and receiver operating characteristic(ROC) curve analysis determined the diagnostic value of urinary Corin in early DKD. Results:Urinary Corin levels were significantly higher in early DKD patients compared to healthy controls, with levels increasing as ACR rose( P<0.05). Urinary Corin was positively associated with serum creatinine( r=0.570), urea( r=0.458), cystatin C( r=0.693), ACR( r=0.616), urinary transferrin( r=0.448), urinary α1 microglobulin( r=0.507), urinary n-acetyl-β-D-glucosaminase( r=0.388) and A subgroup( r=0.692) while was negatively correlated with eGFR( r=-0.647), albumin( r=-0.312)(all P<0.05). eGFR was the only independent factor affecting urinary Corin. After adjusting for confounding factors in logistic regression analysis, urinary Corin was still an independent influencing factor for early DKD. ROC curve analysis indicated that urinary Corin had a diagnostic AUC of 0.842(95% CI 0.791-0.892, P<0.001), with a cut-off value of 2 226.04 pg/mL, sensitivity of 0.712, and specificity of 0.858 for early DKD diagnosis. Conclusions:Urinary Corin was elevated in early DKD patients and correlated with clinical stage. Urinary Corin is an independent factor of early DKD, and a reliable predictor of early DKD diagnosis.

Objective: To evaluate the application of blood conservation measures in obstetric patients with different red blood cell transfusion volumes and to assess the impact of different transfusion volumes on postpartum outcomes. Methods: A retrospective investigation was conducted on 448 obstetric patients who received blood transfusions at the Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to December 2022. Patients were divided into four groups (1-2 units group, 3-4 units group, 5-6 units group, and >6 units group) based on the volumes of red blood cells (RBCs) transfused during and within 7 days after delivery. The maternal physiological indicators, pre- and postpartum laboratory test indicators, obstetric complications, application of blood conservation measures, use of blood products, and postpartum outcomes were reviewed. The clinical characteristics, application of blood conservation measures, and their impact on postpartum outcomes were compared among different transfusion groups. Results: There were statistically significant differences in the multivariate logistic analysis of history of previous cesarean section (OR=1.781), eclampsia/pre-eclampsia/(OR=1.972) and postpartum blood loss>1 000 mL（OR=1.699）(P<0.05) among different transfusion groups. In terms of blood conservation measures, the more RBCs transfused, the higher the rate of mothers receiving blood conservation measures such as balloon occlusion, arterial ligation, autologous blood transfusion with a cell saver, and hysterectomy. With the increase in the volume of RBCs transfusion, the demand for fresh frozen plasma（FFP）, cryoprecipitate, and platelet transfusions also increased. The hospitalization days for the four groups of parturients were 6.0 (4.0-9.0), 7.5 (5.0-14.8), 7.0 (4.5-13.0) and 11.0 (9.0-20.5), respectively (P<0.05) and the rates of ICU transfer were 2.0% (5/250), 9.4% (12/128),18.2% (6/33) and 51.4% (19/37), respectively (P<0.05). Both increased significantly with the increase in the volume of RBCs transfusion, and the differences between groups were statistically significant. Conclusion: Parturients who received higher volume of RBCs had multiple risks factors for bleeding before childbirth, had higher postpartum blood loss, and had a higher rate of application of various blood conservation measures. In addition, an increase in the volume of RBCs transfusion may have adverse effects on postpartum recovery.

Lung transplantation is the ultimate therapeutic option for end-stage pulmonary diseases such as interstitial pneumonia, chronic obstructive pulmonary disease and pneumoconiosis. Currently, the shortage of allogeneic lung donors significantly limits the opportunity for end-stage lung disease patients to receive lung transplantation. In recent years, with the rapid development of biomedical engineering technologies, especially the major breakthroughs in genetic modification and cloning, xenogeneic lung transplantation has shown important potential for clinical translation. Among them, genetically modified pigs have become the most promising xenogeneic lung source due to the close similarity of organ size and physiological characteristics to humans, and the ability to perform targeted gene knockouts (such as α-Gal antigen knockout) to reduce the occurrence of hyperacute rejection. This article focuses on the research progress of porcine xenogeneic lung transplantation, systematically reviews the latest achievements and challenges in animal experiments and human trials, and introduces the technical experience accumulated by Shenzhen Third People's Hospital in the porcine-to-monkey xenogeneic lung transplantation model, in the hope of providing practical references for future research in this field.
