During the progression of ischemic stroke,cells experience oxidative stress and intracellular energy depletion,triggering the dynamic assembly and disassembly of stress granules.Stress granules may have a dual role in ischemic stroke.In the ultra-early reperfusion period(6-36 h),under acute stress,the stress granules may inhibit neuronal apoptosis and exert neuroprotective effects through reversible liquid-liquid phase separation.In contrast,in the acute reperfusion period(36 h to 2 weeks),under prolonged stress,pathological stress granules may accumulate through liquid-solid phase transition,leading to neuronal dysfunction and inducing ischemic stroke sequelae such as motor and cognitive impairments.This article reviewed the mechanisms of stress granules dynamic phase transitions during ischemic stroke and their effects on neurons,aiming to provide references and insights for future stress granule-targeted interventions for ischemic stroke and its sequelae.

Objective To investigate the correlation between cognitive function and medication compliance in patients with type 2 diabetes mellitus(T2DM).Methods Patients with T2DM who were admitted to the Department of Endocrinology,Drum Tower Hospital,Nanjing University School of Medicine from July 2023 to December 2023 were selected.The clinical data and laboratory results of the patients were collected.The medication compliance of the patients was evaluated by Adherence to Refills and Medications Scales(ARMS).And the overall cognitive function and independent cognitive domain tests were performed.According to the diagnostic criteria of mild cognitive impairment(MCI),patients were divided into normal cognitive group and MCI group.Linear regression analysis was used to evaluate the correlation between cognitive function and medication compliance in T2DM patients.Multivariate logistic regression analysis was used to explore the relationship between cognitive dysfunction and poor medication compliance in T2DM patients.Results A total of 216 patients with T2DM were enrolled,including 113 patients with normal cognitive function and 103 patients with MCI.The ARMS score(16.4±4.1 vs.15.1±2.8)and the rate of poor medication compliance(54.4%vs.31.0%)in the MCI group were higher than those in the normal cognitive group(all P<0.05).After adjusting for gender,age,years of education and glycosylated hemoglobin,ARMS scores were significantly negatively correlated with immediate memory,attention and delayed memory scores(all P<0.05).Multivariate logistic regression analysis showed that patients with MCI had a higher risk of poor medication adherence[OR=2.645,95%CI=(1.414,4.946),P<0.001].Conclusions Poor cognitive function,especially memory and concentration,is associated with reduced medication compliance in patients with T2DM.Patients with memory and attention problems should be given appropriate medication advice to improve their compliance in clinical practice.

Objective To investigate the clinical characteristics and prognosis of acute myeloid leukemia(AML)patients with PTPN11 gene mutation.Methods Total 115 adult AML patients who underwent initial diagnosis,treatment,and second-generation sequencing(NGS)detecting at hospital were recruited in this study.Clinical da-ta included disease characteristics,treatment efficacy,long-term prognosis,immune cell subpopulations,and leu-kemia stem cells were collected to analyze the clinical characteristics and prognosis of AML patients with PTPN11 gene mutation.Results PTPN11 gene mutation rate in newly diagnosed adult AML was 9.57％,and the mutation site mainly occurred in exon 3 region with all mutation type being point mutation.Compared with PTPN11 wild-type group,PTPN11 gene mutation group had a higher early mortality rate(18.18％vs 4.00％,P=0.048),a lower complete response rate(33.33％vs 67.71％,P=0.039),a higher recurrence rate(83.33％vs 42.31％,P=0.043),a shorter median overall survival time(9 months vs 20 months,P=0.026),a lower proportion of ef-fector T cells[(1.39±0.12)％vs(3.56±0.46)％,P=0.038],and a higher proportion of leukemia stem cells[(13.82±3.66)％vs(3.87±1.40)％,P=0.021].Conclusion PTPN11 gene mutation is a poor prognostic marker for AML.Those patients have a high early mortality rate,low complete remission rate,high recurrence rate,short median overall survival time,a low proportion of effector T cells,and a high proportion of leukemia stem cells.

Objective To investigate the efficacy of electromagnetic guidance and bedside ultrasound in the placement of nasointestinal feeding tubes in neurocritical care patients,providing a reference for nurses to accurately and efficiently place tubes at the bedside. Methods A tatal of 85 patients were selected as the study subjects,who required nasoenteric tube placement and treated in the department of neurocritical care unit of the First Affiliated Hospital of Zhengzhou University from January 2023 to June 2023. Patients were randomly divided into an experimental group (43 cases) and a control group (42 cases) using a random number table. The experimental group used electromagnetic guidance-assisted nasointestinal tube placement,while the control group utilized bedside ultrasound technology. The differences in the success rate of one-time tube placement,placement time,and complications between the two groups were compared. Results The success rate of one-time tube placement in the experimental group was higher than that in the control group[97.67％ (42/43) vs. 95.24％ (40/42)],but the difference was not statistically significant (P>0.05). The placement time in the experimental group was significantly reduced compared to the control group (minutes:16.23±3.06 vs. 25.07±3.26,P<0.05),and the number of positioning attempts was significantly fewer[attempts:1 (1,3) vs. 3 (3,4),P<0.05]. Scores for theoretical knowledge,operational practice,placement preparation,catheter position visualization,and catheter position interpretation in the experimental group were significantly lower than those in the control group[theoretical knowledge score:2.67±0.52 vs. 4.67±0.52,operational practice score:2.50±0.55 vs. 5.00±0.00,placement preparation score:2.33 (2.00,3.00) vs. 3.00 (2.00,4.00),catheter position visualization score:1.83±0.41 vs. 4.83±0.41,catheter position interpretation score:1.83±0.41 vs. 3.83±0.41,all P<0.05]. The technical difficulty score was significantly lower in the experimental group than in the control group (11.17±0.75 vs. 21.33±0.82,P<0.05). The incidence of nasal bleeding complications in the experimental group was significantly lower than that in the control group[6.98％ (3/43) vs. 23.81％ (10/42),P<0.05]. No other placement complications occurred in either group. Conclusions The success rates of one-time tube placement using electromagnetic navigation and bedside ultrasound for bedside placement of nasointestinal feeding tubes were comparable,but electromagnetic guidance offered higher efficiency and safety. It is suggested that bedside ultrasound be used for gastrointestinal evaluation before electromagnetic guidance-assisted tube placement to assist nurses in implementing personalized pre-placement preparations,thereby further increasing the success rate of tube placement.

Objective:To analyze the epidemiological characteristics of respiratory syncytial virus (RSV) among children in Hebei from 2019 to 2023.Methods:A total of 46 576 lower respiratory tract specimens were collected from hospitalized children in the Children′s Hospital of Hebei Province from 2019 to 2023. Multiple RT-PCR and capillary electrophoresis were used to detect 13 common respiratory pathogens in the specimens, and the results were statistically analyzed.Results:The overall positive rate of RSV was 18.76%(8 739/46 576). The overall positive rates of RSV in male and female children were 18.84%(5 174/27 462) and 18.65%(3 565/19 114), respectively, showing no statistically significant difference between genders (χ 2=0.916, P=0.339). A linear relationship was found between the positive rate of RSV and age ( P<0.01). There was a significant difference in the positive rates of RSV in different years (χ 2=723.71, P<0.01). The positive rate of RSV peaked in the period from December to February from 2019 to 2021. In 2019 and 2020, the positive rates of RSV were very low from May to October, while the positive rate of RSV was above 10% throughout the whole year of 2021 and small off-season epidemics occurred in May and August. The positive rate of RSV was low in 2022, and no significant seasonal change was observed. The rate of RSV infections peaked from April to June in 2023. There were significant differences in the rates of RSV infections before, during and after the COVID-19 epidemic in each age group ( P<0.01). The rate of mixed infections was 29.20%(2 522/8 739), and the most common other respiratory pathogen was human rhinovirus (52.29%, 1 342/2 552 ). Conclusions:RSV is a common pathogen causing respiratory tract infections in children in Hebei, especially in children under 3 years old. After the COVID-19 epidemic, there are off-season RSV epidemics. Given the variations in the epidemiological features of RSV, it is necessary to carry out continuous monitoring of RSV to provide scientific data for the prevention and control of related diseases.
