Objective To evaluate the changes of perivascular space(PVS)in patients with subacute ischemic stroke(IS),as well as the relationship between PVS and cognitive dysfunction in IS patients,and to analyze the relationship between PVS indicators and cognitive function in subacute IS patients of different ages.Methods A total of 44 healthy controls(HC)and 39 patients with subacute IS were prospectively included.Automated quantitative analysis of MRI data was conducted to determine pPVS in the white matter and subcortical regions.Differences in pPVS between patients with subacute IS and HC were compared.Correlations between age,pPVS,and cognitive dysfunction were analyzed and modeled.Results Compared with the HC,the white matter pPVS in patients with subacute IS was significantly reduced(t=-2.21,P=0.031).In patients with subacute IS,the white matter pPVS showed a significant positive correlation with lesion volume(r=0.42,P=0.030)and mini-mental state examination(MMSE)scores(r=0.44,P=0.018).Both white matter pPVS(r=-0.42,P=0.010)and MMSE scores(r=-3.82,P=0.000 7)were negatively correlated with age.When age was over 61.35 years,there was a positive correlation between the white matter pPVS and MMSE scores.Conclusion PVS are closely related to cognitive impairment in patients with subacute IS.Age is a significant modulating factor in the relationship between PVS and cognitive dysfunction.Early monitoring of PVS and targeting it for intervention may positively impact the improvement of cognitive dysfunction following IS.

Suzetrigine is the first approved selec-tive Nav1.8 channel inhibitor.On January 30,2025,the U.S.FDA approved Suzetrigine for the oral treatment of moderate to severe acute pain.In two phase Ⅲ clinical trials(NAVIGATE-1 and NAVIGATE-2),Suzetrigine demonstrated statistically significant improvements in the primary efficacy endpoint,time-weighted sum of pain intensity differences over 48 hours(SPID48),compared with placebo.The least squares mean differences were 29.3(95％CI:14.0-44.6;P=0.000 2)and 48.4(95％CI:33.6-63.1;P＜0.000 1),respectively,confirming its robust analgesic efficacy.Furthermore,owing to its high selectivity for Nav1.8,Suzetrigine exhibited favor-able safety and tolerability profiles,with notably lower incidences of nausea,vomiting,and drug de-pendence compared to conventional opioid analge-sics,underscoring its substantial clinical value.

The Menghe Medical School is a highly influential academic school of Chinese medicine in China.Its academic features are mainly learning from others'strengths,openness and tolerance;integrity as the foundation,communication as the strength;harmo-ny as the way,and agility as the technique.The Menghe Medical School originated in Menghe,developed in Shanghai,spread all over the country,and spread around the world.The reasons for the prosperity and development of the Menghe Medical School are analyzed.Among them,imperial doctors being rewarded and supported,the stars having their roots in Menghe,inheritance from teach-ers by blood,help from in-laws,and the establishment of education and leadership in development are the main factors.On the basis of inheriting the scholarship of Menghe Medical School,Professor Tong Xiaolin innovatively proposed academic ideas such as the train-ing path of Xiang thinking,state-target differentiation and treatment,and dosage and effectiveness of prescriptions and medicines,pushing the academic thought of Menghe Medical School to a new theoretical peak in the new era.Based on the majestic development path of the Menghe Medical School,the implications for the inheritance,innovation and development of modern Chinese medicine are analyzed.

Objective To observe the characteristics of magnetic resonance angiography of(MRA) ophthalmic artery in patients with diabetic retinopathy (DR).Methods A total of 36 eyes of DR patients (DR group) diagnosed by clinical examination were included in the study.Among them,there were 42 eyes in 21 males and 15 eyes in 15 females.The average age was 55.2 years old.The average duration of diabetes was 7.56 years.All eyes were examined by MRA and fluorescein fundus angiography (FFA) in the ophthalmic artery.At the same time,24 eyes of 12 patients were examined by computed tomography angiography (CTA).Twenty-two healthy volunteers with age and gender matching were selected as the control group.Among them,there were 13 males and 9 females.All patients underwent MRA examination of the ophthalmic artery;at the same time,5 eyes of 5 eyes were examined by CTA.MRA and CTA were classified into three grades according to the development condition and shape change of the ophthalmic artery.0 grade:no abnormality;grade Ⅰ:mild lesion;grade Ⅱ:obvious lesion.According to the results of FFA examination,it was divided into no obvious disease stage,background stage,proliferative stage,proliferative stage.The morphological features of the MRA of the ophthalmic artery in the DR group and the control group were compared.The relationship between the MRA grading of the ophthalmic artery and the FFA staging was observed in the DR group.The consistency analysis between the MRA and CTA grades of the ophthalmic artery in the DR group was performed by Kappa test;the relationship between the MRA grade and the FFA staging of the ophthalmic artery was analyzed by Spearson correlation analysis of the same data with two-way ordered attributes.Results In 44 eyes of the control group,the MRA in grade 0 and Ⅰ of the ophthalmic artery were 41 and 3 eyes,respectively;all eyes of the CTA examination of the ophthalmic artery were grade 0.In 72 eyes of the DR group,the MRA in grade 0,Ⅰ,and Ⅱ of the ophthalmic artery were 28,28,and 16 eyes,respectively.Among the 24 eyes examined by CTA,there were 13,6,and 5 eyes in grade 0,Ⅰ,and Ⅱ,respectively.In the DR group,the classification of MRA and CTA of the ophthalmic artery was highly consistent (Kappa value =0.86).There were significant differences in the number of eyes with different grades of MRA in the DR group and the control group (Z=-5.74,P=0.000).In 72 eyes of the DR group,there were 8,12,22,and 30 eyes in no obvious disease stage,background stage,proliferative stage,and proliferative stage,respectively.Correlation analysis showed that there was a significant correlation between MRA grading and FFA staging in the DR group (r=0.405,P=0.000).Conclusions MRA can show the changes of ophthalmic artery morphology and reflect DR staging to a certain extent.It has a high consistency with FFA vascular changes.

Objective To investigate the effect of a Chinese medicine formula GAPT, a combination containing Chinese herbs ginseng,Acorus tatarinowii, Polygala and tuber curcuma, on the behavior and cholinergic system in mice with scopolamine-induced memory impairment, and to explore the neuroprotective mechanism of GAPT. Methods ICR mice were randomly divided into normal control group(solution of 0.5% carboxy methyl cellulose, CMC), model group (0.5% CMC),positive control group(donepezil, 0.92 mg/(kg·d)), GAPT high, medium and low dose groups(20 mg/(kg·d),10 mg/(kg·d),5 mg/(kg·d)),18 mice in each group, were given intragastric gavage once a day for 30 days. After the last administration,the control group and model group received intraperitoneal injection of normal saline,and the other groups intraperitoneal injection of scopolamine(3 mg/(kg·d)), dissolved in 0.9% normal saline. Morris water maze test was performed to assess the learning and memmory ability. Then the mice were killed and the Ach content and AchE and ChAT activity in the cortex and hippocampus were detected. Results GAPT increased the swimming dis-tance,swimming time and the residence time in target quadrant of the model mice,increased the content of Ach and the ac-tivity of ChAT,and decreased the activity of AchE in the brain of the model group. Conclusions GAPT can improve the learning and memory ability of mice induced by scopolamine,and its mechanism may be related to cholinergic system.
