4.Evaluation of imaging characteristics and clinical application value of multi-slice spiral CT angiography in subarachnoid hemorrhage
Chinese Journal of Postgraduates of Medicine 2020;43(12):1089-1093
Objective:To evaluate the imaging characteristics and etiology of subarachnoid hemorrhage (SAH) by multi-slice spiral CT angiography (CTA).Methods:A total of 68 SAH patients admitted to Xinchang People′s Hospital from July 2018 to December 2019 were selected as study subjects. CTA and digital subtraction angiography (DSA) were performed on all subjects to compare the detection results of CTA and DSA.Results:Taken DSA results as the "gold standard", this study included 68 SAH patients, including 44 cases of aneurysm detected by DSA correctly, 16 cases of arteriovenous malformation and 8 cases of normal. CTA correctly detected 61 cases, including 45 cases of aneurysms, 16 cases of arteriovenous malformations and 7 cases of normal cases. One case was misdiagnosed as aneurysm, and the diagnosis coincidence rate was 98.53% (67/68). There was no significant difference between CTA and DSA in the detection results of tumor body width and neck width [(6.63 ± 0.75) mm vs. (6.58 ± 0.77) mm, (3.55 ± 0.47) mm vs. (3.49 ± 0.45) mm] ( P > 0.05). Conclusions:CTA has the advantages of non-invasive, rapid and convenient diagnosis of the etiology of SAH, which is conducive to the selection and assessment of clinical surgical treatment.

Purpose:
This study aimed to investigate reproductive concerns among breast cancer patients of reproductive age, analyze the influencing factors, explore the relationship between coping styles, fear of progression (FOP), and reproductive concerns, and identify the multiple effects of coping styles on the relationship between FOP and reproductive concerns among Chinese breast cancer patients.
Methods:
A cross-sectional, descriptive study was conducted among breast cancer patients in four tertiary grade A hospitals in Fujian, China, from January 2022 to September 2022. A total of 210 patients were recruited to complete paper-based questionnaires, which included the general data questionnaires, the Reproductive Concerns After Cancer Scale (RCACS), the Fear of Progression Questionnaire-Short Form (FOP-Q-SF), and the Medical Coping Modes Questionnaire (MCMQ). Structural equation models were utilized to evaluate the multiple effects of coping styles on FOP and reproductive concerns.
Results:
Reproductive concerns in breast cancer patients had a mean score of 53.02 (SD, 10.69), out of a total score of 90, and coping styles for cancer (confrontation, avoidance) were closely associated with FOP and reproductive concerns. FOP showed a significant positive correlation with reproductive concerns (r = .52, p < .01). At the same time, confrontation was significantly negatively correlated with both FOP (r = −.28, p < .01) and reproductive concerns (r = −.39, p < .01). Avoidance was positively correlated to both FOP (r = .25, p < .01) and reproductive concerns (r = .34, p < .01). The impact of FOP on reproductive concerns is partially mediated by confrontation and avoidance, with effect sizes of .07 and .04, respectively. These mediating factors account for 22.0% of the total effect.
Conclusions
The FOP directly impacted reproductive concerns, while coping styles could partially mediate the association between FOP and reproductive concerns. This study illustrates the role of confrontation and avoidance in alleviating reproductive concerns, suggesting that it is necessary to focus on the changes in reproductive concerns among reproductive-age breast cancer patients. Healthcare professionals can improve disease awareness and reduce patients' FOP, thereby promoting positive psychological and coping behaviors and ultimately alleviating reproductive concerns.

Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia seen in clinical settings, which has been associated with substantial rates of mortality and morbidity. However, clinically available drugs have limited efficacy and adverse effects. We aimed to investigate the mechanisms of action of andrographolide (Andr) with respect to AF. We used network pharmacology approaches to investigate the possible therapeutic effect of Andr. To define the role of Andr in AF, HL-1 cells were pro-treated with Andr for 1 h before rapid electronic stimulation (RES) and rabbits were pro-treated for 1 d before rapid atrial pacing (RAP). Apoptosis, myofibril degradation, oxidative stress, and inflammation were determined. RNA sequencing (RNA-seq) was performed to investigate the relevant mechanism. Andr treatment attenuated RAP-induced atrial electrophysiological changes, inflammation, oxidative damage, and apoptosis both in vivo and in vitro. RNA-seq indicated that oxidative phosphorylation played an important role. Transmission electron microscopy and adenosine triphosphate (ATP) content assay respectively validated the morphological and functional changes in mitochondria. The translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) to the nucleus and the molecular docking suggested that Andr might exert a therapeutic effect by influencing the Keap1-Nrf2 complex. In conclusions, this study revealed that Andr is a potential preventive therapeutic drug toward AF via activating the translocation of Nrf2 to the nucleus and the upregulation of heme oxygenase-1 (HO-1) to promote mitochondrial bioenergetics.
