Intracranial branch atheromatous disease (BAD) was proposed by Caplan in 1989.It has been widely studied in Japan in recent years.With the application of high-resolution magnetic resonance,BAD has become a hot topic.This article reviews the concept,etiology,pathology,diagnosis and treatment of BAD as well as its relationship with ischemic stroke.

The incidence of colorectal polyp shows an upward trend, and some types of colorectal polyps, may evolve into colorectal cancer. Dyslipidemia is not only related to the occurrence of cardiovascular diseases, but also related to the occurrence and development of colorectal polyps. Hyperlipidemia can directly or indirectly stimulate the proliferation of colorectal mucosal cells and lead to tumorigenesis. Exploring the factors affecting the occurrence and recurrence of colorectal polyps may be conducive to prevent and manage the disease. General practitioners should pay attention to the high-risk group of colorectal polyps, and timely health education and colonoscopy screening are important measures to prevent its occurrence and further cancer development.

Objective:To study the medication rules of treating cervical spondylosis by National TCM master Liu Bailing based on data mining and network pharmacology, and explore the potential action mechanism of its core compounds.Methods:By collecting the prescriptions of National TCM master Liu Bailing treating cervical spondylosis in the past 8 years, this paper analyses the frequency, nature, flavor, meridian, hierarchical clustering and association rules of those prescriptions by RStudio to obtain the core prescription. Then, the effective components of the core prescription were collected by using TCMSP, and the network of "medicine-component-target" was constructed by using Cytoscape 3.8.0; by searching for databases like GEO, DisGeNET, TTD HPO and Genecards were retrieved to obtain the target data set of cervical spondylosis; by using STRING 11.0 platform to construct protein interaction network; by using DAVID platform to cary out gene ontology (GO) and KEGG pathway enrichment analysis; by using Auto Dock software for molecular docking.Results:In the 844 prescriptions, there are 199 Chinese medicines and the properties are mainly warm, plain and cold; the flavors were mainly sweet, pungent and bitter; mainly belong to the liver, spleen, and kidney meridians. The Association Rule shows that the core compound is made up of Salvia miltiorrhiza, Gastrodia elata, Rhizoma corydalis, Alisma rhizoma, centipede, Astragalus membranaceus and Rhizome of Pueraria. Besides, 140 effective constituents and 247 targets of the core prescription were screened, and the main constituents were quercetin, kamanol, luteolin, tanshinone ⅡA, β-sitosterol, etc. 13 core targets among the core prescription treating cervical spondylosis were obtained, which were enriched into 30 pathways including toll-like receptor signaling pathway, TNF signaling pathway and HIF-1 signaling pathway. Conclusion:National TCM master Liu Bailing treatment of cervical spondylosis mainly focuses on expelling wind and relieving pain, dredging meridians and soothing tendons, and the mechanism of action of the core prescription may focus on inhibiting inflammatory response and relieving oxidative stress, providing guidance and reference for the clinical treatment of cervical spondylosis.

Objective:To investigate the effect of clinical factors on the short-term prognosis of patients with acute carbon monoxide toxic heart disease.Methods:From October 2017 to December 2019, 92 patients with acute carbon monoxide poisoning (ACOP) and toxic heart disease admitted to the Department of Emergency of our hospital were enrolled in this study. The duration from poisoning to hospital admission, duration of coma, length of hospital stay, endotracheal intubation or not, admission to ICU ward or not, acute physiology and chronic health evaluation (APACHEⅡscore) at admission were recorded. The heart rate-corrected QT dispersion (QTcd) calculated based on electrocardiography results, as well as levels of serum trocalin I (cTnI) and creatine kinase isoenzyme (CK-MB) were recorded at admission, day 2, day 3, and hospital discharge. According to the diagnostic criteria of occupational cute toxic cardiopathy caused by chemicals, the patients were divided into three groups: 45 cases in the mild heart disease group (mild group), 35 cases in the moderate heart disease group (moderate group) and 12 cases in the severe heart disease group (severe group). The variables data of each group were presented as Mean±SD, and analyzed using one-way anova test. LSD- t test was used for pairwise comparison between the groups. Attributes data were compared using χ 2 comparisontest, and correlations were analyzed using Spearman correlation method and binary logistic regression analysis. Results:APACHE II score was significantly higher, and the durations of coma, and hospitalization time of severe heart disease group were significantly higher longer in the severe heart disease group than those ofin the mild and moderate groups, and the proportions of patients with early tracheal intubation to protect airway and admission in ICU ward were both significantly lower in the severe heart disease group than those ofin the mild and moderate moderate groups (all P < 0.05). The levels of CTnI and QTcd in each group increased immediately after admission, which was statistically different from that in the normal control group ( P < 0.05), while cTnI and QTcd at admission in the severe group were significantly higher than those in the mild and moderateother two groups ( P < 0.05). The levels of CK-MB in the severe group wereas significantly different from thoseat of the mild to and moderate groups at day 2 and day 3 after admission ( P < 0.05). The correlation between serum cTnI and APACHE II score at admission was R1 = 1.000 and R2 = 0.458. The correlation between QTcd and APACHE II score at admission was R1 = 1.000 and R2 = 0.765. Both of them were positively correlationsed with statistical difference ( P < 0.01). Conclusions:Patients with ACOP should admit to hospital as early as possible. For patients with severe hypoxia and no airway protection ability, an artificial airway should be established as soon as possible, and the patients should admit to the ICU at the early stage of poisoning to stabilize their condition. Changes of QTcd, serum cTnI, CK-MB and other related indicators should be monitored to detect cardiac injury in time and protect heart.

Objective:To observe the peripapillary atrophy (PPA) and peripapillary choroidal vascularity index (CVI) in patients with different degrees of myopia and to analyze their correlations.Methods:A cross-sectional clinical study. From September 2021 to December 2021, 281 mypoic patients of 281 eyes treated in Eye Hospital of Wenzhou Medical University at Hangzhou were included in this study, and the right eye was used as the treated eye. There were 135 eyes in 135 males and 146 eyes in 146 females. The age was 28.18±5.78 years. The spherical equivalent refraction (SE) was -5.13±2.33 D. The patients were divided into three groups: low myopia group (group A, -3.00 D

Electrocardiogram (ECG) signal is an important basis for the diagnosis of arrhythmia and myocardial infarction. In order to further improve the classification effect of arrhythmia and myocardial infarction, an ECG classification algorithm based on Convolutional vision Transformer (CvT) and multimodal image fusion was proposed. Through Gramian summation angular field (GASF), Gramian difference angular field (GADF) and recurrence plot (RP), the one-dimensional ECG signal was converted into three different modes of two-dimensional images, and fused into a multimodal fusion image containing more features. The CvT-13 model could take into account local and global information when processing the fused image, thus effectively improving the classification performance. On the MIT-BIH arrhythmia dataset and the PTB myocardial infarction dataset, the algorithm achieved a combined accuracy of 99.9% for the classification of five arrhythmias and 99.8% for the classification of myocardial infarction. The experiments show that the high-precision computer-assisted intelligent classification method is superior and can effectively improve the diagnostic efficiency of arrhythmia as well as myocardial infarction and other cardiac diseases.
