Objective To investigate the correlation between apathy and imaging markers in pa-tients with aCSVD.Methods A total of 143 patients diagnosed with aCSVD and hospitalized in the Department of Neurology of the First Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology from August 2023 to August 2024 were continu-ously included as the study objects.According to MAES,they were divided into an apathetic group(MAES score＞14,68 cases)and a non-apathetic group(MAES score ≤14,75 cases).The clinical data and imaging markers were compared between the two groups.Results The apathetic group had significantly older age and larger ratio of hypertension,but shorter years of education and lower MAES score than the non-apathetic group(P＜0.05,P＜0.01).The apathetic group also had notably higher Fazekas score of white matter hyperintensity(WMH),larger recent small sub-cortical infarct(RSSI),lacunar infarct(LI),and perivascular space(PVS)in the basal ganglia and the centrum semiovale,more obvious cerebral atrophy and cerebral microbleed(CMB),and high-er total imaging burden score when compared with the non-apathetic group(P＜0.01).In the aCSVD patients,the MAES score was positively correlated with WMH Fazekas score,RSSI,LI,basal ganglia PVS,centrum semiovale PVS,cerebral atrophy,CMB,and total imaging burden score(P＜0.01).WMH Fazekas score was an independent risk factor for apathy in the aCSVD patients(OR=2.218,95％CI:1.343-3.664,P=0.002).Conclusion The higher the score of ima-ging markers in patients with aCSVD,the more severe the apathy.

Objective: To investigate the molecular mechanisms and pathways of action of total flavonoids of Dracocephalum moldavica L.(TFDM) in treating vascular cognitive impairment(VCI) based on network pharmacology and in vivo animal experiments. Methods : The swiss target prediction database, literature, and PubChem were used to screen the active components and action targets of TFDM. The online mendelian inheritance in man(OMIM) and GeneCards databases were utilized to screen for possible VCI targets. Venny software was used to obtain the intersection target of TFDM and VCI. The search tool for recurring instances of neighbouring genes(String) database and Cytoscape software was used to construct the PPI network. The database for annotation, visualization and integrated discovery(DAVID) database was utilized to screen for the kyoto encyclopedia of genes and genomes(KEGG) pathway and gene ontology(GO) enrichment analyses to explore the molecular mechanism and signaling pathway of TFDM for VCI. 24 rats were divided into Sham, Model, Donepezil, and TFDM groups. Except for the Sham group, the VCI model was created using modified bilateral common carotid artery ligation. After continuous gavage for 21 days, the Morris water maze test was used to evaluate the spatial learning and memory ability of rats. Hematoxy-lineosin(HE) staining was used to observe the pathological changes in the hippocampal CA1 and cortex region of the animals and immunohistochemistry detection of zonula occludens-1(ZO-1) content in the brains of the rats. Western blot was used to detect nuclear factor kappa-B p65(NF-κB p65) and tumor necrosis factor-α(TNF-α) in rat brains. Results : A total of 39 active ingredients of TFDM were screened, 209 corresponding targets, 10 417 gene targets of VCI, and 193 intersecting targets. According to the results of the GO enrichment of function analysis, TFDM could improve the response of reactive oxygen species and metabolic processes of reactive oxygen species, etc. KEGG pathway enrichment analysis suggested that TFDM might regulate TNF, IL-17 signing pathway, etc. The results of animal experiments showed that TFDM improved learning and memory while reduced pathological damage in the brains of VCI rats. In addition, TFDM upregulated the positive expression of ZO-1 and downregulated the protein levels of TNF-α and NF-κB p65(P<0.05). Conclusion TFDM can improve the cognitive function of VCI through multi-components and multi-targets, and its key mechanism may be related to inhibiting TNF-α/NF-κB p65 signaling pathway,reducing neuroinflammation,and improvement of blood-brain barrier permeability.

The emerging endoscopic technologies are proved to be effective treatments for obesity in selected patients and to offer the potential advantages of reduced invasiveness, reversibility and repeatability. From the view of operation principle, endoscopic technologies can be classified as restrictive procedure, malabsorption procedure and endoscopic revision of gastric bypass. Restrictive procedures include intragastric balloon, aspiration therapy, endoscopic sleeve gastroplasty (ESG) and transoral gastroplasty. Intragastric balloon employs space occupying, volume restriction and satiety mechanisms, which is superior to drugs and lifestyle change, but shorter than sleeve and bypass surgery. Aspiration therapy is similar to standard percutaneous endoscopic gastrostomy, while there are no available data regarding the obesity and metabolic improvement. Compared with traditional bariatric surgery, ESG does not excise gastric tissue with less complications and without weight regain, but it can not be used as an independent operation still now. Transoral gastroplasty is rarely applied clinically whose efficacy and long-term complications need further studies. Malabsorption surgery includes endoscopic duodenojejunal bypass sleeve (EDJBS) and endoscopic gastroduodenojejunal bypass sleeve(EGDJBS). EDJBS may have the similar mechanism like bypass reducing the blood glucose. Even with obvious effect of weight loss, EDJBS has high morbidity of complications and requirements of the skilled operators. EGDJBS, which imitates bypass anatomy changes and belongs to the mixed operation, should be superior to the above procedures in reducing weight theoretically, but due to the lack of clinical data, its short-term and long-term efficacy still need further clinical observation. As compared to the complexity and risks associated with telescopic surgical revision, endoscopic suturing has been confirmed as less invasive and safer for stomal revisions, while its long-term efficacy of reducing weight and improvement of diabetes are not yet clear. Even if long-term efficacy of reducing weight and morbidity of complication in endoscopic bariatric surgery are still indefinite, and clinical trial researches of large sample and long-term follow-up are absent, with the development of endoscopic skill and the gradual clinical application, endoscopic bariatric surgery will provide a new option for the patients of obesity and metabolic diseases.
