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.

Objective To investigate the methylation levels of the HIF-3α gene,as well as the expression of HIF-3α mRNA and DDIT4 mRNA in peripheral blood samples from pregnant women with gestational diabetes mellitus(GDM),and their association with pregnancy outcomes,aiming to provide insights for pregnancy monitoring and clinical diagnosis and treatment of GDM patients,thereby mitigating the risk of adverse pregnancy outcomes.Methods From March 2023 to March 2024,a total of 80 pregnant women with GDM were randomly selected at the Affiliated Hospital of Xuzhou Medical University.They were divided into two groups based on glycemic control:GDM1(n=40)representing good glycemic control and GDM2(n=40)representing poor glycemic control.Addi-tionally,a control group consisting of 40 pregnant women without any pregnancy complications or comorbidities was included.Methylation-specific PCR was employed to determine the rate of HIF-3α methylation,while quantita-tive real-time PCR was used to assess the expressions of HIF-3α mRNA and DDIT4 mRNA.Adverse pregnancy outcomes were recorded across all three groups,and correlations between HIF-3α mRNA,DDIT4 mRNA,and various adverse pregnancy outcomes were analyzed using logistic regression analysis.Results Prior to pregnancy,GDM1 and GDM2 groups exhibited higher levels of FPG,HbA1c,TC,TG,LDL-C,FINS and HOMA-IR(P＜0.05),as well as lower levels of HOMA-β compared to the control group(P＜0.05).The incidence of adverse pregnancy outcomes was also higher in both GDM groups than in the control group;this difference was significant for GDM2(P＜0.05)but not for GDM1(P＞0.05).Furthermore,methylation rates of the HIF-3α gene were higher in both GDM groups compared to controls while expression levels of HIF-3α and DDIT4 mRNA were lower;these differences were significant for the GDM2 group versus controls(P＜0.05)but not for the GDM1 group ver-sus controls(P＞0.05).Finally,all adverse pregnancy outcomes among women with gestational diabetes mellitus showed a negative correlation with expression levels of both HIF-3α and DDIT4 mRNA(r＜0,P＜0.05);moreover,these two mRNAs served as protective factors against such outcomes occurring(OR＜1,P＜0.05).Conclusion The higher methylation rate of HIF-3α and the decreased expression of HIF-3α and DDIT4 genes are associated with the development of GDM and may serve as significant factors contributing to adverse pregnancy outcomes.

Objective To investigate the level of platelet parameter of uterine cervical cancer patients and its clinical significance. Methods Seventy-four cases with cervical cancer (the observation group) from Ningde Municipal Hospital, the Affiliated Hospital of Fujian Medical University from May 2014 to May 2016 were chosen as the research subjects. Seventy-four cases of healthy people were treated as the control group. According to the International Federation of Gynecology and Obstetrics (FIGO), the observation group was divided into 15 cases under stage ⅡB(the early stage group), 59 cases of ⅡBstage and above (the middle and advanced stage group). Platelet count (Plt) and mean volume of platelet were monitored and compared by using Japan automatic blood cell analyzer. Results Plt in the observation group was higher than that in the control group [(266 ±71) × 109/L vs. (215 ±42) × 109/L, respectively], and the difference was statistically significant (t = 5.322, P＜ 0.05). The average volume of platelet in the observation group was lower than that in the control group [(9.2±1.2) fl vs. (9.9±1.3) fl, respectively], and the difference was statistically significant (t =-3.931, P ＜ 0.05); There was no statistical difference in the Plt and mean volume of platelet between the early stage group and the middle and advanced stage group (both P＞0.05). Conclusions The determination of platelet parameter has a certain clinical significance for screening and early detection of uterine cervical cancer.
