Atherosclerosis (AS) is a common underlying disease that hazard to human health.It is closely associated with stroke,hypertension,coronary artery disease,and diabetes.AS on the premise of vascular intimnal injury,excessive smooth muscle cell proliferation,inflammatory cell infiltration,oxidative stress,apoptosis and other mschanisms participate together.In eucaryotic organisms,most proteins are degraded by ubiquitin-proteasome system (UPS).An increasing number of evidence indicates that UPS is associated with the occurrenee and development of AS and complications.This article reviews the relationship between.UPS and AS,as well as the effect of ubiquitin-proteasome inhibitor on AS.

Objective To study the effects of rehabilitation training on the expression of Nogo-A around the area of cerebral infraction using rats. Methods A total of 60 Wistar rats were randomly divided into a reha- bilitation group and a control group after an experimental cerebral infarction had been established in them. The ani- mals in the rehabilitation group were given exercise with a rotating bar, a balance beam and a rolling cage for one hour daily, while those in the control group were caged without any abnormal exercise. Nogo-A expression in the ar- ea surrounding the infarcts was detected by imunohistochemical techniques at the 3rd, 7th, 14th, 21st and 28th day after infarction. Meanwhile, neurobehavioral evaluations were also conducted. Results The animals in the rehabilitation group scored much lower than the controls in the behavioral evaluations at the 14th, 21st and 28th day. The expression of Nogo-A in tissues around the infracted area increased by the 7th day and peaked at the 21st day in both groups, but the expression of Nogo-A was significantly stronger in the rehabilitation group at the 14th, 21st and 28th days. Conclusion Rehabilitation training decreased the expression of Nogo-A in the brain of rats after infarction. This may have important implications for the functional recovery of the central nervous system.

Objective:To develop the Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with Inflammatory Bowel Disease (IBD), and test its reliability and validity.Methods:Guided by the theory of knowledge, attitude, and practice, a preliminary draft of the scale was formed through literature review, Delphi expert consultation, and pre-survey. From May to August 2022, convenience sampling was used to select 200 IBD patients who visited the Gastroenterology Clinic of three ClassⅢ Grade A comprehensive hospitals in Jiangsu Province as the research subject for a questionnaire survey. The critical ratio method, correlation analysis method, internal consistency method, commonality and factor loadings were used for item analysis of the scale. Exploratory factor analysis, content validity index, and internal consistency reliability were applied to test the reliability and validity of the scale.Results:A total of 200 questionnaires were distributed, and 181 valid questionnaires were collected, with an effective response rate of 90.50% (181/200). The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD included three dimensions of knowledge, attitude and practice, with a total of 21 items. The content validity index at the scale level was 0.917, and the content validity index at the item level ranged from 0.833 to 1.000. Exploratory factor analysis extracted three common factors, with a cumulative variance contribution rate of 74.197%. The Cronbach's α coefficient of the total scale was 0.951, and the coefficients of each dimension were 0.914 to 0.942. The test-retest reliability coefficient of the total scale was 0.918, and the test-retest reliability coefficients of each dimension ranged from 0.737 to 0.833.Conclusions:The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD has good reliability and validity, which can help medical and nursing staff evaluate patients' understanding and acceptance of microbial transplantation, so as to provide a basis for personalized communication in shared decision making between doctors and patients.
