Objective To study the relationship between cognitive dysfunction and location of lesion and prognosis in patients with cerebral infarction.Methods 120 patients with cerebral infarction in the Second People's Hospital of Yueqing were selected.According the results of the cerebral CT or MRI,the patients were divided into primary group(58 cases)and recurrence group (62 cases).3 -10days after admission,the cognitive impairment was evaluated with the method of simple mental state examination (MMSE)scale.The stroke score of the National Institutes of health(NIHSS)in the United States and ability of daily life activity Barthel index score before the admission and after the discharge were conducted on the patients.And the relationship between different lesion location of primary or recurrent infarction,cognitive disability and prognosis were observed.Results The incidence of cognitive impairment in the ecurrence group was 90.32%,which was obviously higher than 72.41% in the primary group(χ2 =6.419,P =0.011);In the two groups,the proportion of thalamic cortex was the highest,but there was no significant difference between the two groups (χ2 =0.000,P =1.000).The NIHSS and Barthel scores of patients with thalamic infarction were (11.4 ±1.6)points and (27.5 ±3.7)points respectively,both of which were the highest(FNIHSS =47.22, PNIHSS =0.000;FBarthel index =17.77,PBarthel index =0.000);the NIHSS and Barthel indexes in each part of the two groups at discharge were lower than those before the admission (all P <0.01),and the differences at admission was not statistically significant(P >0.05);the NIHSS scores of the primary group and the recurrent group at discharge were (6.3 ±0.5)points and (7.8 ±0.7)points respectively;the Barthel scores were (24.3 ±7.3)points and (30.8 ± 6.8)points respectively.And all of them were lower than those at admission and the improvement degree of the primary group were more significant than those of the recurrence group(tNIHSS =13.43,PNIHSS =0.000;tBarthel index =5.05, PBarthel index =0.000).Conclusion Cognitive impairment after cerebral infarction is associated with lesion,and thalamic infarction is the most prone to perform cognitive disfunction with poor prognosis,and the frontal and temporal lobe are also common parts where targeted prevention is needed.

Objective:To explore the potential categories and associated factors of mild cognitive impairment (MCI) in community-dwelling older adults.Methods:A total of 393 community-dwelling older adults with MCI in Huzhou City were selected through multistage random sampling from January to July 2022.The survey was conducted by the general information questionnaire, Montreal cognitive assessment (MoCA), Pittsburgh sleep quality index (PSQI) and 15-item geriatric depression scale(GDS-15). Latent profile analysis (LAP) was applied to explore latent categories based on the characteristics of cognitive impairment, and Logistic regression analysis was performed to examine the factors associated with these MCI categories. The statistical software was SPSS 26.0.Results:The community-dwelling older adults with MCI was categorized into four subgroups: generalized mildly impaired subgroup, mixed impaired with visuospatial executive dysfunction subgroup, narrative memory dysfunction impaired subgroup, and high-risk severely impaired subgroup, with corresponding MoCA scores of (23.10±0.96), (21.87±0.92), (20.43±0.93), (19.00±0.00), PSQI scores of (6.00 (4.00)), (7.00 (6.00)), (7.00 (6.00)), (10.00 (3.00)), and GDS-15 scores of (4.00 (4.00)), (4.00(5.00)), (6.00(5.00)), (8.00 (3.00)), respectively. Logistic regression analysis revealed that compared to generalized mildly impaired subgroup, gender, age, exercise habits, sleep quality, depressive symptoms, chronic disease count, and medication count significantly affected other three subgroups, with female, older age, and never/irregular exercise as common risk factors. Poor sleep quality and depressive symptoms could positively predict mixed impaired with visuospatial executive dysfunction subgroup and narrative memory dysfunction impaired subgroup( B=0.82, OR=2.27, 95% CI=1.26-4.08; B=1.12, OR=3.06, 95% CI=1.36-6.91).Additionally, poor sleep quality, depressive symptoms, chronic disease and medication count could significantly predict high-risk severely impaired subgroup ( B=4.13, OR=62.32, 95% CI= 1.71->999.99; B=3.31, OR=27.49, 95% CI=1.37-549.99; B=1.20, OR=3.32, 95% CI= 1.06-10.41 and B=0.80, OR=2.22, 95% CI=1.04-4.71). Conclusion:Four latent MCI categories are identified among community-dwelling older adults, and each category was characterized by unique cognitive impairment features and factors. Healthcare professionals are advised to customize assessments and management strategies according to these specific characteristics to effectively slow cognitive decline.

Objective To conduct a survey on students for their common needs for the course and the support to their research training,to provide reference for course reform and curriculum of ideology and politics.Methods A survey before and after course was conducted in 704 graduates who selected the course of"Experiments of Molecu-lar Biology"from the autumn of 2018 to the spring of 2024.After collecting the survey,they were summarized,counted,and analyzed.Results The students selected this course were mainly research-oriented graduate students.Their professional background was mainly in clinical medicine,and there was a relatively lack of training in tech-nology and laboratory skill in molecular biology experiment.The follow-up survey showed that experimental operation and implementation as well as analysis of experimental results were the two most helpful aspects for students;PCR,RNA extraction and detection,and Western blot were the most useful techniques for student learning and scientific research.Conclusions Through the survey,the professional background of students,dynamic changes in their course selection needs are well acknowledged and so thus able to optimize,provide good reference for teaching and learning in this field,and provide a basis for curriculum reform and construction of ideological and political courses.
