Stroke-related sarcopenia (SRS) is a secondary sarcopenia caused by stroke, typically characterized by a rapid decline in muscle mass and structural changes following the onset of stroke. At present, there is a lack of clinical research on the diagnosis and treatment of SRS, and its mechanism of occurrence is complex, which cannot be explained by post-stroke apraxia alone, leading to significant difficulties in screening and intervening in SRS. This article reviews the pathogenesis, specific manifestations, screening, risk factors and predictive biomarkers of SRS, its impact on patients, and possible prevention and intervention strategies.

Objective:To explore the mediating role of kinesiophobia in the relationship between illness perception and cardiac rehabilitation willingness among patients with coronary heart disease.Methods:Using the convenient sampling method, a total of 255 patients with coronary heart disease who were admitted to Cardiovascular Department of the Second Affiliated Hospital of Chongqing Medical University from June to September 2022 were selected as the research objects. The survey was conducted using a general information questionnaire, Chinese version of the Tampa Scale for Kinesiophobia Heart (TSK-Heart-C) , Heart Rehabilitation Scale and Chinese version of Brief Illness Perception Questionnaire.Results:The total score of TSK-Heart-C in 255 patients with coronary heart disease was (38.53±9.27) , the total score of Heart Rehabilitation Scale was (49.90±12.53) , and the total score of Chinese version of Brief Illness Perception Questionnaire was (53.04±15.90) . Disease perception had a direct effect on heart rehabilitation willingness (β=-0.378, P<0.01) , kinesiophobia played a mediating role between illness perception and heart rehabilitation willingness (β=-0.254, P<0.01) , and the mediating effect accounted for 40.19% of the total effect. Conclusions:Kinesiophobia is a mediating variable between cardiac rehabilitation willingness and illness perception. Medical staff should pay attention to the level of kinesiophobia in patients with coronary heart disease, provide correct health education, improve patients' correct understanding and compliance with the disease, take correct cardiac rehabilitation measures and effectively improve quality of life of patients.

Objective:To evaluate the effect of prior statins use on the in-hospital mortality of adult sepsis patients with type 2 diabetes (T2DM).Methods:A total of 3 545 sepsis patients with T2DM were retrospectively collected from the Critical Care Medical Information Market (MIMIC Ⅳ) database, with in-hospital mortality rate as the outcome variable. According to whether they have taken statins in the past, they were divided into two groups and propensity score matching was used. Multivariate Cox regression analysis was performed to calculate the adjusted hazard ratio ( HR) and 95% CI, and the relationship between past statins use and in-hospital mortality in sepsis patients with T2DM was analyzed. Results:A total of 3 545 sepsis patients with T2DM were included between 2008 and 2016. 1 556 patients used statins before admission, and 1 989 patients did not use statins. After propensity score matching, the number of patients who had previously used statins and those who had not used statins were 1 230 and 1 298, respectively. After adjusting for potential confounding factors, it was found that previous use of statins was associated with a reduced in-hospital mortality rate ( HR=0.82, 95% CI: 0.61-0.99, P=0.038). Kaplan Meier curves showed that sepsis patients with T2DM who used statins before admission had a lower in-hospital mortality rate (Log rank test: P<0.001). Conclusions:Pre admission use of statins may be associated with a reduced mortality rate in sepsis patients with concomitant T2DM.

Objective:To investigate the effects of ceftriaxone(CTX) on nuclear factor erythroid 2-related factor 2(Nrf2)/glutathione peroxidase 4(GPX4) pathway and ferroptosis in early brain injury in rats with subarachnoid hemorrhage(SAH).Methods:Forty-eight clean grade male SD rats were randomly divided into sham operation group (Sham group), SAH group, SAH+ CTX group and SAH+ CTX+ Nrf2 inhibitor group (SAH+ CTX+ ML385 group) according to the random number table with 12 rats in each group.Seven days before modeling, rats in SAH+ CTX+ ML385 group were injected intraperitoneally with ML385 (30 mg · kg -1) once a day for consecutive 7 days.And 5 days before modeling, rats in SAH+ CTX group and SAH+ CTX+ ML385 group were treated with CTX(200 mg · kg -1) by intraperitoneal injection once a day for five consecutive days.Rats in Sham group and SAH group were intraperitoneally injected with the same amount of 0.9% sodium chloride solution.After 24 hours of modeling, the neurological function score and brain tissue water content of rats in each group were measured.HE staining was used to observe the morphology of neurons in CA1 and CA3 regions of hippocampus.Prussian blue staining was used to observe the iron deposition in cerebral cortex.Spectrophotometer was used to determine the iron content, malonic dialdehyde(MDA) content, glutathione(GSH) content and GPX4 activity in cerebral cortex.Western blot was used to detect the expression levels of Nrf2 and GPX4 proteins in cerebral cortex.SPSS 23.0 was used for statistical analysis.One-way ANOVA was used to compare the mean of multiple groups of samples, and Dunnett- t test was used for further pairwise comparison between groups. Results:There was a statistically significant difference in the neurological function scores of rats in the four groups 24 hours after SAH ( F=48.40, P<0.001). The neurological function score of rats in the SAH group 24 hours after SAH was significantly lower than those in Sham group and SAH+ CTX group (both P<0.05). The brain water content of rats in the four groups 24 h after SAH was statistically significant ( F=49.61, P<0.001). The brain water content of rats in the SAH group 24 h after SAH was significantly higher than that in Sham group and SAH+ CTX group(both P<0.05). There was statistically significant differences in the number of neuronal necrosis in CA1 and CA3 regions of hippocampus in the four groups 24 hours after SAH ( F=17.44, 246.50, both P<0.001). The numbers of neuronal necrosis in CA1 and CA3 regions of hippocampus in SAH group were significantly higher than those in Sham group and SAH+ CTX group, and the numbers of neuronal necrosis in CA1 and CA3 regions of hippocampus in SAH+ CTX+ ML385 group were significantly higher than those in SAH+ CTX group (all P<0.05). Twenty-four hours after SAH, the amount of iron deposited in the cerebral cortex of rats in the four groups was statistically significant ( F=2 363.0, P<0.001). The iron deposition in the cerebral cortex of rats in the SAH group was significantly higher than those in Sham group and SAH+ CTX group (both P<0.05). There were significant differences in iron content, MDA content, GSH content and GPX4 activity in the cerebral cortex of the four groups 24 h after SAH( F=2 380.0, 1 322.0, 789.1, 815.5, all P<0.001). The content of iron and MDA in the cerebral cortex of rats in SAH group were significantly higher than those in Sham group, while the content of GSH and the activity of GPX4 were significantly lower than those in Sham group (all P<0.05). The content of iron and MDA in the cerebral cortex of rats in SAH+ CTX group were lower than those in SAH group, and the content of GSH and the activity of GPX4 were higher than those in SAH group (all P<0.05). At 24 h after SAH, the expression levels of Nrf2 and GPX4 protein in the cerebral cortex of the four groups were statistically significant ( F=888.7, 1 556.0, both P<0.001). The protein expression levels of Nrf2 (0.382±0.014) and GPX4 (0.329±0.019) in the cerebral cortex in SAH group were lower than those in Sham group ((0.746±0.009), (0.953±0.009)) (both P<0.05). The expression levels of Nrf2 (0.631±0.006) and GPX4 (0.833±0.008) protein in the cerebral cortex in the SAH+ CTX group were significantly higher than those in the SAH group (both P<0.05). The expression levels of Nrf2 (0.427±0.009) and GPX4 (0.525±0.011) protein in the cerebral cortex in SAH+ CTX+ ML385 group were significantly lower than those in SAH+ CTX group (both P<0.05). Conclusion:Ceftriaxone may inhibit ferroptosis during EBI in SAH rats by regulating Nrf2/GPX4 signal axis.
