ObjectiveTo investigate the unfavorable factors of intestinal mucosa repair after the intestinal epithelial injury in vivo in a mouse model of sepsis. MethodsThe method of cecal ligature and puncture (CLP) was used to induce sepsis and then the intestinal mucosa damage, epithelial cell apoptosis and the number of transformed goblet cells were observed, and the concentrations of serum TNF-αt, IL-1 and TGF-β1 and TFF3 ( trefoil factor 3) in small intestinal mucosa were determined. All above various laboratory examinations were made by different assays including H-E staining, western blot, ELISA and immunohistochemistry respectively. The experimental mice were divided into sepsis group and sham operation control group. The mice with sepsis were separately sacrificed 6 hours ( n = 7 ), 24 hours ( n = 7) and 48 hours ( n = 7) after CLP. Results In septic mice group, the injured intestinal mucosa was found 6 hours after CLP. The damage scores in mice 24 h and 48 h after CLP were higher than those 6 h after CLP, but there was no significant difference between those 24 h and 48 h after CLP. Moreover, a few goblet cells or other epithelial cells adjacent to the injured surface migrated onto the wound to cover the denuded area. The number of goblet cells was substantially decreased in mice of sepsis group 6 hours after CLP compared with sham operation control group. Compared with sham operation control group, levels of IL-1 and TNF-α significantly increased 3-4 times in mice of sepsis group at all intervals, and the phosphorylated caspase-3 increased 4 times. Although TFF3 assayed by using Western blot showed modest increase 6 h after CLP and it declined 24 h and 48 h later. A similar change was found in TGF-β1, it modestly increased 6h after CLP, but it didn't elevate 24 h and 48 h later. ConclusionsSevere sepsis keeps on the inflammatory reaction and epithelial cell apoptosis, preventing the repair of intestinal mucosa from injury.

Objective:To investigate associations between cardiac biomarkers with stroke severity and short-term outcome in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Affiliated Hospital of Qingdao University from June 2018 to February 2024 whose etiological classification was large artery atherosclerosis (LAA), small vessel occlusion (SVO) or cardioembolism (CE) were included retrospectively. According to the National Institutes of Health Stroke Scale score at admission, patients were divided into mild stroke group (≤8) and moderate to severe stroke group (>8). According to the modified Rankin Scale score at discharge, patients were divided into good outcome group (≤2) and poor outcome group (>2). Multivariate logistic regression analysis was used to determine the independent correlation between cardiac biomarkers and short-term outcome. The predictive value of cardiac biomarkers for poor outcome in patients with AIS and different stroke etiology subtypes were evaluated using receiver operating characteristic (ROC) curves. Results:A total of 2 151 patients with AIS were enrolled, including 1 256 males (58.4%), aged 67.40±11.34 years. 1 079 patents were LAA type (50.2%), 679 were SVO type (31.6%), and 393 were CE type (18.3%); 1 223 were mild stroke (56.86%) and 928 (43.14%) were moderate to severe stroke; 1 357 patients (63.09%) had good short-term outcome, and 794 (36.91%) had poor short-term outcome. Multivariate logistic regression analysis showed that N-terminal pro-B type natriuretic peptide (NT-proBNP), NT-proBNP/creatine kinase (CK) isoenzyme MB (CK-MB) ratio, and CK-MB/CK ratio were independent risk factors for poor short-term outcome. ROC curve analysis shows that the CK-MB/CK ratio had a higher predictive value for short-term poor outcome in patients with AIS (the area under the curve, 0.859, 95% confidence interval 0.839-0.879). Various cardiac biomarkers had a higher predictive value for short-term outcome of CE type and LAA type, but the predictive value for short-term outcome of SVO type was lower. Conclusions:Cardiac biomarkers are associated with the severity and poor outcome of AIS. NT-proBNP/CK-MB and CK-MB/CK ratios have higher predictive value for short-term poor outcome of AIS, especially in patients with CE type.

Objective To investigate the clinical effect of air moxibustion combined with pushpin-like needle acupuncture,which is formulated based on the"suppressing wood-supporting earth"theory in the doctrine of the five elements of Traditional Chinese Medicine(TCM),in the treatment of pain,nausea and vomiting after transcatheter arterial chemoembolization(TACE).Methods A total of 160 patients with hepatocellular carcinoma,who were admitted to the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine of China to receive initial TACE between July 2020 and June 2023,were enrolled in this study.The patients were randomly divided into 4 groups with 40 patients in each group.The patients of the control group received TACE with conventional nursing care,the patients of the pushpin-like needle group received pushpin-like needle acupuncture on the basis of the control group,the patients of the air moxibustion group received air moxibustion treatment on the basis of the control group,and the patients of the combination group received air moxibustion combined with pushpin-like needle acupuncture on the basis of the control group.The post-TACE pain degree(VAS scoring)and nausea/vomiting extent(INVR scoring)were compared between each other among the four groups.Results The differences in the VAS score and INVR score(including main effect and interaction effect)between each other among the four groups were statistically significant(all P＜0.05).Statistically significant differences in the VAS score and INVR score existed between the control group and the other three groups(all P＜0.05).The differences in the VAS score and INVR score between combination group and pushpin-like needle group,as well as between combination group and air moxibustion group were statistically significant(both P＜0.05).Conclusion Air moxibustion combined with pushpin-like needle acupuncture can effectively and remarkably relieve post-TACE pain,nausea and vomiting,which is superior to simple use of air moxibustion or pushpin-like needle acupuncture.Therefor,the combination use of air moxibustion and pushpin-like needle acupuncture should be popularized in clinical practice.
