Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

Objective: To investigate the mental health status and related factors among primary and secondary school students in western Yunnan Province, so ao to provide scientific evidences for advancing mental health education. Methods: In June 2024, a stratified cluster sampling method was employed to select 4 584 students from 18 schools across Diqing Tibetan Autonomous Prefecture, Lincang City and Baoshan City three regions in western Yunnan Province. The Mental Health Test (MHT) was used for assessment. Latent class analysis (LCA) and Logistic regression were applied for data classification and related factor analysis respectively. Results: The overall positive detection rate of MHT was 11.81%, with a mean total score of 40.50±19.25. The predominant issues were learning anxiety (58.4%), hypersensitivity tendency (31.1%), and self blame tendency (23.1%). LCA categorized students into four groups:severe psychological problems group (74.4% detection rate), learning anxiety hypersensitivity group ( 16.4 %), learning anxiety physical symptoms group (9.2%), and healthy group (0). Logistic regression revealed that compared with the healthy group, the severe problems group showed higher risks among females ( OR =3.01), junior/senior high school students ( OR =1.88/4.02), and those with authoritarian parenting ( OR =3.54); the anxiety hypersensitivity group had higher risks for females ( OR =1.87), senior high students ( OR =1.54), boarders ( OR =1.31), and authoritarian parenting recipients ( OR = 1.85 ); the anxiety physical symptoms group demonstrated increased risks among females ( OR =2.22), senior high students ( OR =2.58), and authoritarian parenting recipients ( OR =2.74), while lower risks were observed for students with parent/grandparent guardians ( OR =0.38) and non only children ( OR =0.58) (all P <0.05). Conclusions Mental health problems are prominent among students in western Yunnan, with gender, grade level, boarding status, guardian type, and parenting style being key determinants. Recommendations include strengthening mental health education, prioritizing left behind children s psychological well being and promoting healthy development.

The surveillance data of new cases of acute myocardial infarction (AMI) from January 1, 2013, to December 31, 2021, in Tengzhou City, Shandong Province, were used to analyze the incidence rate of AMI and its change trend among residents. The age and gender standardized incidence rate was calculated based on the 7th National Population Census 2020. The Cochran-Armitage trend test was used to analyze the trend of onset time and age. From 2013 to 2021, the crude and standardized incidence rate of total AMI in Tengzhou City declined from 130.07/100 000 and 161.12/100 000 to 76.15/100 000 and 72.77/100 000 ( Z=-13.785 and -20.822, both P<0.001). The crude and standardized incidence rates of males were higher than those of females. In 2016, males aged 45-54 years old and females aged 35-64 years old increased by 33.33%, 103.65%, 106.30%, and 95.75% compared to 2015, and the differences were statistically significant ( χ2=6.512, 4.965, 25.115, and 46.004, all P<0.05). The incidence rate of AMI in men aged<35 and 35-44 years old had an upward trend. From 2013 to 2021, the incidence rate of AMI decreased by 55.15% in urban areas and 36.59% in rural areas ( Z=-8.529 and -11.235, both P<0.001).

Objective To construct a mouse model of psoriasis with spleen deficiency and dampness obstruction pattern and evaluate the model from multiple dimensions and directions,expects to provide research support for the study of traditional Chinese medicine (TCM) treatment of psoriasis with spleen deficiency and dampness obstruction pattern. Methods A mouse model of spleen deficiency and dampness obstruction pattern was established by feeding a high-fat diet,a mouse model of psoriasis vulgaris was established by externally applying imiquimod ointment,and a mouse model of psoriasis with spleen deficiency and dampness obstruction pattern was constructed by combining the above two models. Indications of spleen deficiency and dampness obstruction pattern were evaluated by comparing the body mass,food intake and water intake of mice in each group. The severity of psoriasis in mice was evaluated by comparing the area of skin lesions,PASI score,the value of transdermal water loss (TEWL),and histopathological morphological changes of skin under HE staining in each group. Flow cytometry was used to detect the expression in various cell types to evaluate the degree of inflammatory response of psoriasis in mice. Observation of adiposity index,changes in the histopathological morphology of liver tissue under HE staining,changes in the mRNA expression levels of related factors in liver tissue and adipose tissue of epididymis of mice detected by RT-qPCR,and changes of ABCA1 protein expression level of skin detected by Western Blot were used to evaluate the lipid metabolism disorders in mice. Results Compared with the mice in the psoriasis vulgaris model group,the mice in the model of psoriasis with pattern of spleen deficiency and dampness obstruction had significantly higher body mass (P<0.001),significantly lower food intake (P<0.005),and the symptoms of pattern of spleen deficiency and dampness obstruction such as greasy fur,mental fatigue,etc. appeared. The TWEL were significantly increased(P<0.001),and the PASI scores also significantly increased(P<0.001). HE results were found psoriasis-like manifestations including hypertrophy of the spinous layer and clubbed hyperplasia. The expression of CD11bhighLy6G+neutrophil subpopulation,CD11binLy6Chigh monocyte subpopulation,CD11binCD11chigh classical dendritic cell subpopulation,F4/80-CD11c+dendritic cell subpopulation was significantly increased (P<0.001). HE staining suggested that the cellular morphology of liver showed obvious vacuolated degeneration,and the index of subcutaneous white adiposity and epididymal adiposity index were both significantly increased (P<0.005). The mRNA levels of FABP4 and CD36 in liver tissue were significantly elevated(P<0.005,P<0.001),while the mRNA expression levels of ABCA1 and PPARγ in epididymal fat tissue were decreased (P<0.05,P<0.01). ABCA1 protein level in skin increased(P>0.05). Conclusion The mouse model of psoriasis with spleen deficiency and dampness obstruction pattern can be used as a reliable animal model for combining disease and pattern,which can provide a reference for further exploration of TCM in the treatment of psoriasis with spleen deficiency and dampness obstruction pattern.
