  • Pyroptosis is an inflammatory form of programmed cell death that is linked with invading intracellular pathogens. Cardiac pyroptosis has a significant role in coronary microembolization (CME), thus causing myocardial injury. Tanshinone IIA (Tan IIA) has powerful cardioprotective effects. Hence, this study aimed to identify the effect of Tan IIA on CME and its underlying mechanism. Forty Sprague-Dawley (SD) rats were randomly grouped into sham, CME, CME + low-dose Tan IIA, and CME + high-dose Tan IIA groups. Except for the sham group, polyethylene microspheres (42 ㎛) were injected to establish the CME model. The Tan-L and Tan-H groups received intraperitoneal Tan IIA for 7 days before CME. After CME, cardiac function, myocardial histopathology, and serum myocardial injury markers were assessed. The expression of pyroptosis-associated molecules and TLR4/MyD88/NF-κB/NLRP3 cascade was evaluated by qRT-PCR, Western blotting, ELISA, and IHC. Relative to the sham group, CME group's cardiac functions were significantly reduced, with a high level of serum myocardial injury markers, and microinfarct area. Also, the levels of caspase-1 p20, GSDMD-N, IL-18, IL-1β, TLR4, MyD88, p-NF-κB p65, NLRP3, and ASC expression were increased. Relative to the CME group, the Tan-H and Tan-L groups had considerably improved cardiac functions, with a considerably low level of serum myocardial injury markers and microinfarct area. Tan IIA can reduce the levels of pyroptosis-associated mRNA and protein, which may be caused by inhibiting TLR4/MyD88/NF-κB/NLRP3 cascade. In conclusion, Tanshinone IIA can suppress cardiomyocyte pyroptosis probably through modulating the TLR4/MyD88/NF-κB/NLRP3 cascade, lowering cardiac dysfunction, and myocardial damage.

  • Purpose To explore cerebrovascular reservoir (CVR) and arterial transit time (ATT) changes using acetazolamide-challenged multi-phase arterial spin labeling (MP-ASL) perfusion-weighted MRI in chronic cerebrovascular steno-occlusive disease. Materials and Methods This retrospective study enrolled patients with chronic steno-occlusion who underwent acetazolamide-challenged MP-ASL between June 2019 and October 2020. Cerebral blood flow, CVR, basal ATT, and ATT changes associated with severe stenosis, total occlusion, and chronic infarction lesions were compared. Results There were 32 patients (5 with bilateral steno-occlusion) in our study sample. The CVR was significantly reduced during total occlusion compared with severe stenosis (26.2% ± 28.8% vs. 41.4% ± 34.1%, respectively, p = 0.004). The ATT changes were not significantly different (p = 0.717). The CVR was marginally lower in patients with chronic infarction (29.6% ± 39.1% vs. 38.9% ± 28.7%, respectively, p = 0.076). However, the ATT was less shortened in patients with chronic infarction (-54 ± 135 vs. -117 ± 128 ms, respectively, p = 0.013). Conclusion Acetazolamide-challenged MP-ASL provides an MRI-based CVR evaluation tool for chronic steno-occlusive disease.

  • Purpose: The purpose of this study was to assess the importance and contribution of 9 nursing outcomes and their indicators that could be applied to cerebrovascular patients. Methods: Data were collected from 175 neurosurgical nurses working at two university affiliated hospitals and five secondary hospitals located in Gwang-ju. The Fehring method was used to estimate outcome content validity(OCV) and outcome sensitivity validity(OSV) of nursing outcomes and their indicators. Stepwise regression was used to evaluate relationship between outcome and its indicators. Results: The core outcomes identified by the OCV were Tissue Perfusion: Cerebral, Nutritional Status, Neurological Status, and Wound Healing: Primary Intention, whereas highly supportive outcomes identified by the OSV were Oral Health, Self-Care: ADL, and Nutritional Status. All the critical indicators selected for Fehring method were not included in stepwise regression model. By stepwise regression analysis, the indicators explained outcomes from 19% to 52% in importance and from 21% to 45% in contribution. Conclusion: This study identified core and supportive outcomes and their indicators which could be useful to assess the physical status of cerebrovascular patients. Further research is needed for the revision and development of nursing outcomes and their indicators at neurological nursing area.

  • This study was conducted to investigate serum lipids and antioxidant vitamins status of male patients with cerebrovascular disease. The study consisted of 16 hospital patients(57.8$\pm$13.7 years) at 3 General Hospitals in Taegu who suffer from cerebrovascular disease and 21 healthy adults(55.5$\pm$7.2 years). The results were as follows: The systolic blood pressure of the patients(150.0$\pm$13.7mmHg) was sig nificantly higher than healthy control(126.0$\pm$17.4mmHg). In patients the percentages of drinking alcohol(more than 5 times/week) and smoking were also higher. And the patients had more stress than control. Total calorie, protein, carbohydrate, vitamin B1 and niacin intakes were significantly lower in the patients. The energy nutrients consumption reached the recommended level in all subjects who were investigated. HDL cholesterol(24.99 vs 37.86mg/dl) and vitamin E(12.94 vs 20.88mg/L) level showed significantly lower, but triglyceride level(175.50 vs 117.69mg/dl), total cholesterol/HDL cho lesterol(6.22 vs 4.39) and atherogenic index(5.22 vs 3.39) were significantly higher in the patient group. Therefore, it might be expected that refraining from drinking alcohol and smoking, and that having proper exercise and certain other healthy living habits which can decrease stress in addition suitable consumption of antioxidant vitamins can prevent the occurrence of cerebrovascular disease.

  • Purpose: This study was conducted to identify relationships between depression, family support, and rehabilitation-motivation in patients with cerebrovascular accident. Method: The data were collected from 'S' hospital in Seoul from Feb. 1, 2004 to Apr. 30, 2004. The data were analyzed using a SPSS 10.0 program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. Result: The results were as follows: The mean rehabilitation-motivation was 119.89, which was slightly high. The rehabilitation-motivation was influenced by religion, education level, occupation, economic status, treatment fee, duration of hospitalization, level of language ability and ADL. Rehabilitation-motivation has showed correlation with family support (r=.538, p=.000) and depression (r=-.417, p=.000). The variables related to rehabilitation-motivation were identified as family support, level of ADL, occupation, depression, and education level, using stepwise multiple regression. They were accounted for 57% of predictability of the rehabilitation-motivation, with the family support the highest at 29.3%. Conclusion: With increasing post stroke patients in Korea, we need to pay more attention to the rehabilitation of them. This study indicates that health professionals need to focus on the intervention especially in increasing family support and in decreasing depression of the patients with cerebrovascular accident.

  • The association between apolipoprotein E (apo E) gene polymorphism and ischemic cerebrovascular disease (ICVD) has been controversial. These controversies may be due to inaccurate classification of patients and ethnic differences. We investigated the association between apo E genotypes and ICVD patients by case-control study in a Korean population. The association between apo E polymorphism and ICVD was examined in 121 patients with ICVD and 132 controls without ICVD. The E3/E4 phenotype was more frequent in control subjects (23.8%) than in patients (13.0%) (p<0.05). The E2/E3 phenotype was more frequent in patients (14.8%) than in control subjects (10.8%), but the difference was not statistically significant (p>0.05). These results suggest that the E4 allele may be a protective factor against early vascular morbidity, and the E2 allele may be a risk factor for cerebrovascular morbidity.

  • Purpose: The purpose of this study was to examine the effect of the discharge education program on compliance with the sick role behavior for patients having undergone cerebrovascular surgery. Method: Research was done using a posttest only design. The subjects were 60 patients who were admitted to the neurosurgery unit at C.N.U. Hospital in G. City and were divided into the experimental and control groups. The discharge education program were intervened two times in the experimental group by the researcher; the first one was at the time of discharge using a booklet about knowledge related to disease and compliance, and the other one was a telephone education session after a week from discharge. Data were collected two times by interview and telephone using questionnaires from January 19, to June 10, 2000. The first one was at hospital before discharge, and the other one was one month later from discharge. Data were analysed by $\chi^{2}$, t-test, ANOVA, and Pearson's correlation. Results: The experimental group showed a higher score of compliance(t=2.772, p=.008) than those of the control group, but knowledge about CVD was not significant between the two groups(p>.05). Conclusion: The discharge education program was effective on the compliance of the patients having undergone cerebrovascular surgery.
