ObjectiveTo investigate the effects of modified Buyang Huanwu Tang on cerebral ischemia-reperfusion injury （CI/RI） in mice via the PTEN-induced putative kinase 1/E3 ubiquitin ligase （PINK1/Parkin） signaling pathway-mediated mitophagy， and to explore the underlying mechanism by which modified Buyang Huanwu Tang improves CI/RI. MethodsSeventy-two male C57BL/6J mice were randomly divided into six groups （n = 12 per group）： Sham-operated group， middle cerebral artery occlusion/reperfusion （MCAO/R） model group， low-， medium-， and high-dose modified Buyang Huanwu Tang groups （8.84， 17.68， 35.36 g·kg^-1·d^-1）， and an aspirin group （13.00 mg·kg^-1·d^-1）. Neurological deficit scores were assessed using the Zea-Longa method. Cerebral infarct volume ratio was measured by 2，3，5-triphenyltetrazolium chloride （TTC） staining. Histopathological changes and neuronal injury in brain tissues were observed using hematoxylin-eosin （HE） staining and Nissl staining. Apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling （TUNEL） assay. Mitochondrial ultrastructure in brain tissue was observed by transmission electron microscopy （TEM）. Serum levels of superoxide dismutase （SOD） and malondialdehyde （MDA） were determined by enzyme-linked immunosorbent assay （ELISA）. The mRNA and protein expression levels of PINK1， Parkin， microtubule-associated protein 1 light chain 3B （LC3B， LC3Ⅱ/Ⅰ）， and p62 in brain tissues were detected by real-time quantitative reverse transcription PCR （Real-time PCR） and Western blot， respectively. ResultsCompared with the sham-operated group， the MCAO/R model group showed significantly increased neurological deficit scores and cerebral infarct volume ratios （P<0.01）. Severe cortical injury on the infarct side was observed， characterized by decreased neuronal density， cytoplasmic vacuolation， nuclear pyknosis， a marked reduction in Nissl bodies， dissolution of Nissl bodies in the cytoplasm of some pyramidal neurons， and blurred cellular boundaries. The number of TUNEL-positive cells increased significantly （P<0.01）. Mitochondria exhibited cristae membrane rupture and matrix vacuolation， with rupture of the outer mitochondrial membrane and formation of autophagosomes， the number of which increased significantly. Serum SOD activity decreased significantly （P<0.01）， while MDA content increased significantly （P<0.01）. In infarcted brain tissues of model mice， the relative mRNA expression and protein levels of PINK1， Parkin and LC3B were significantly increased （P<0.05， P<0.01）， whereas p62 mRNA and protein expression were significantly decreased （P<0.05， P<0.01）， showing statistical significance. Compared with the model group， all treatment groups showed significantly decreased neurological deficit scores and cerebral infarct volume ratios （P<0.01）. Neuronal density increased significantly， cytoplasmic vacuolation was alleviated， nuclear morphology tended to be more regular and clearer， Nissl body density increased significantly with reduced dissolution and improved contour clarity. The mitochondrial cristae structure was partially restored， with some mitochondria showing autophagosome encapsulation， and the degree of mitochondrial damage was alleviated. Serum SOD activity increased significantly （P<0.01）， while MDA content decreased significantly. The mRNA and protein expression levels of PINK1， Parkin， and LC3Ⅱ/Ⅰ were significantly increased （P<0.05， P<0.01）， while p62 mRNA and protein expression in the low- and medium-dose modified Buyang Huanwu Tang groups were significantly decreased （P<0.05， P<0.01）， showing statistical significance. ConclusionModified Buyang Huanwu Tang can upregulate the protein expression levels of PINK1， Parkin， and LC3Ⅱ/Ⅰ and downregulate p62 protein expression， suggesting that it may improve CI/RI by regulating the expression of proteins related to the PINK1/Parkin signaling pathway. Regulation of the mitophagy pathway may be one of the mechanisms by which modified Buyang Huanwu Tang alleviates CI/RI in mice.

Objective In this study,the potential profile characteristics of exercise self-efficacy of patients with inflammatory bowel disease(IBD)were explored,and the influencing factors of different types of patients were an-alyzed,so as to provide a reference for nurses to formulate standardized management measures.Methods From June 2023 to May 2024,a total of 342 hospitalized patients with IBD in tertiary A hospital in Wuxi were recruited as research subjects by a convenience sampling method.The General Information Questionnaire,Exercise Self-effica-cy Scale,Exercise Behavioral Stage Distribution Scale and the Social Support Rating Scale were used for investiga-tion.The latent profile analysis was conducted to classify exercise self-efficacy levels,while multiple Logistic regres-sion analysis was utilized to evaluate the influencing factors.Results A total of 320 valid questionnaires were col-lected,and the effective questionnaire recovery rate was 93.57％.The total score of exercise self-efficacy for IBD pa-tients was(64.61±14.83)points.The exercise self-efficacy was classified into 3 latent categories:low efficacy-somatic emotion group(n=64,20.00％),medium efficacy-work conflict group(n=158,49.38％),and high efficacy-social interfer-ence group(n=98,30.62％).Occupation,recurrence times,comorbid chronic diseases,self-assessed economic pressure,and social support level were found to be influencing factors of the latent profile classification of exercise self-effi-cacy in IBD patients(P＜0.05).Conclusion The levels of exercise self-efficacy of patients with IBD are significant-ly heterogeneous,and there are several important influencing factors.Nursing staff should formulate targeted inter-vention strategies based on the characteristics of exercise self-efficacy in such patients,so as to improve patients' exercise self-efficacy and the effectiveness of disease rehabilitation.

Objective:To analyze the influencing factors of mood state of common rheumatic (rheumatoid arthritis; systemic lupus erythematosus; ankylosing spondylitis) patients and find out the common characteristics of patients with negative emotions, so as to identify and treat rheumatic patients with anxiety and depression in clinical practice.Methods:A total of 205 patients with rheumatism (83 with rheumatoid arthritis, 74 with systemic lupus erythematosus, 48 with ankylosing spondylitis) admitted to the Shandong Provincial Hospital Affiliated to Shandong University from April to May 2023 were included. The general condition and POMS of patients were collected. All patients were divided into 3 groups of low-TMD/ middle-TMD/ high-TMD(TMD≤90 scores; 90 scores105 scores). The χ2 test was used for categorical variables, and the continuous variables were tested for normal distribution. If they followed a normal distribution, the independent sample t test (for homogeneous variance) or the Welch′s t test (for unequal variance) was used for comparison between the two groups, and one-way analysis of variance was used for comparison between multiple groups; if they did not follow a normal distribution, the Kruskal-Wallis H test was used for comparison between groups. Patients with TMD>90 scores were defined as the negative emotion group. Gender, age, education level, economic income status, and TMD were included in the two-step cluster analysis (TCA) to obtain three cluster groups and analyze the differences between the groups. Logistic regression was used to analyze the risk factors. Results:The study found that patients with rheumatic diseases with low serum albumin levels ( F=6.26, P=0.003), low education level ( χ2=8.36, P=0.015), low economic level ( χ2=15.59, P<0.001), short disease course ( H=28.01, P<0.001), and high disease activity ( χ2=56.93, P<0.001) had higher TMD scores, which was not related to the type of disease ( χ2=4.81, P=0.090). The negative mood group had a higher proportion of females (57.6% vs. 73.4%, χ2=5.16, P=0.023), a shorter course of disease [24(12, 48) months vs. 48(24, 93) months, Z=13.58, P<0.001], and a lower serum albumin [(42.2±4.0) g/L vs. (44.0±3.4)g/L, t=-14.09, P=0.002], low level of education ( χ2=9.04, P=0.029), low level of income ( χ2=10.29, P=0.036), high disease activity ( χ2=61.91, P<0.001). The results of cluster analysis indicated that the above factors were significantly different among the three cluster groups except the course of disease. It is noteworthy that age ( F=19.25, P<0.001) and serum albumin ( F=5.64, P=0.004) had the lowest value and the highest TMD score ( F=5.64, P<0.001). Regression analysis showed that gender, disease course and disease activity were related factors to the occurrence of negative emotions, and high disease activity was a risk factor [ OR(95% CI) =26.58(4.53, 156.09), P<0.001]. Men [ OR(95% CI)=0.20 (0.08, 0.50), P=0.001) and the course of [ OR(95% CI)=0.99 (0.98, 1.00), P=0.007) as the protective factors. Conclusion:Male, serum albumin level, education level, income level, disease course and disease activity were the main factors affecting the mood state of patients with rheumatism, in which high disease activity was the risk factor, male and long disease course were the protective factors.

objective To investigate the prognostic value of plasma ADAMTS13 in patients with heart failure complicated with type 2 diabetes mellitus(T2DM).Methods Clinical data were collected from adult patients with acute decompensated heart failure admitted to the Second People's Hospital of Yulin City from January 2019 to December 2020,with a total of 278 cases included.The level of ADAMTS13 was measured using an ELISA kit,and patients were divided into three groups based on the third quartile of ADAMTS13:T1<9.9 μg/L group(n=92),T2≥10.0-18.5 μg/L group(n=93),and T3≥18.5 μg/L group(n=93).The primary outcome was defined as the composite end point of all-cause mortality's or heart failure readmission.Secondary outcomes included all-cause mortality and heart failure readmission.Results Compared with the patients in the highest third quartile of ADAMTS13,the number of T2DM cases,body mass index,uric acid,fasting blood glucose,HbA1c and hs-CRP levels in the patients with the lowest third quartile of ADAMTS13 increased significantly(P<0.05).The absolute risks of main outcome,all-cause death and hospitalization of heart failure were higher in T2DM patients than in non-T2DM patients(χ2=12.028,8.725,9.023,all P=0.000).The differences in heart failure rate among patients with different ADAMTS13 levels were statistically significant(χ2=9.384,P=0.002).Every doubling of ADAMTS13 was related to a decreased risk of the main outcomes in HF patients with T2DM(HR=0.69,95%CI=0.61～0.79),all-cause mortality(HR=0.59,95%CI=0.47～0.74)and heart failure readmission(HR=0.75,95%CI=0.65～0.87).Conclusion ADAMTS13 is an independent biomarker for risk stratification in HF,especially in patients with T2DM.
