RESUMO
Objective:To explore the current situation and influencing factors of quality of life of septic patients in intensive care unit (ICU) after discharge, and to provide theoretical basis for clinical early psychological intervention and continuity of care.Methods:A prospective observational study was conducted. The septic patients who were hospitalized in the department of critical care medicine of the Affiliated Hospital of Jining Medical University and discharged with improvement from January 1 to December 31, 2022 were selected as the research objects. The demographic information, basic diseases, infection site, vital signs at ICU admission, severity scores of the condition within 24 hours after ICU admission, various biochemical indexes, treatment process, and prognostic indexes of all the patients were recorded. All patients were assessed by questionnaire at 3 months of discharge using the 36-item short-form health survey scale (SF-36 scale), the activities of daily living scale (ADL scale), and the Montreal cognitive assessment scale (MoCA scale). Multiple linear regression was used to analyze the factors influencing the quality of life of septic patients after discharge from the hospital.Results:A total of 200 septic patients were discharged with improvement and followed up at 3 months of discharge, of which 150 completed the questionnaire. Of the 150 patients, 57 had sepsis and 93 had septic shock. The total SF-36 scale score of septic patients at 3 months of discharge was 81.4±23.0, and the scores of dimensions were, in descending order, role-emotional (83.4±23.0), mental health (82.9±23.6), bodily pain (82.8±23.3), vitality (81.6±23.2), physical function (81.4±23.5), general health (81.1±23.3), role-physical (79.5±27.0), and social function (78.8±25.2). There was no statistically significant difference in the total SF-36 scale score between the patients with sepsis and septic shock (82.6±22.0 vs. 80.7±23.6, P > 0.05). Incorporating the statistically significant indicators from linear univariate analysis into multiple linear regression analysis, and the results showed that the factors influencing the quality of life of septic patients at 3 months after discharge included ADL scale score at 3 months after discharge [ β= 0.741, 95% confidence interval (95% CI) was 0.606 to 0.791, P < 0.001], length of ICU stay ( β= -0.209, 95% CI was -0.733 to -0.208, P = 0.001), duration of mechanical ventilation ( β= 0.147, 95% CI was 0.122 to 0.978, P = 0.012), total dosage of norepinephrine ( β= -0.111, 95% CI was -0.044 to -0.002, P = 0.028), mean arterial pressure (MAP) at ICU admission ( β= -0.102, 95% CI was -0.203 to -0.007, P = 0.036) and body weight ( β= 0.097, 95% CI was 0.005 to 0.345, P = 0.044). Conclusions:The quality of life of patients with sepsis at 3 months after discharge is at a moderately high level. The influencing factors of the quality of life of patients with sepsis at 3 months after discharge include the ADL scale score at 3 months after discharge, the length of ICU stay, the duration of mechanical ventilation, the total dosage of norepinephrine, MAP at ICU admission and body weight, and healthcare professionals should enhance the treatment and care of the patients during their hospitalization based on the above influencing factors, and pay attention to early psychological intervention and continued care for such patients.
RESUMO
Abnormal FGFR signaling has been found in a variety of cancers. The abnormal FGFR signaling is involved in several processes of tumorigenesis which include cell survival, proliferation, inflammation, migration, angiogenesis, epithelial-mesenchymal transformation and drug resistance. Therefore, FGFR is a very promising target for the treatment of tumors. More and more FGFR inhibitors have been developed for preclinical and clinical trials, and some FGFR inhibitors have been used in clinical applications. However, the problems such as acquired resistance and systemic toxicity have hindered the application of FGFR inhibitors. This paper reviews the clinical application of common FGFR inhibitors and summarizes the problems and solutions in their application.
RESUMO
Graphene oxide (GO) nanomaterials have significant advantages for drug delivery and electrode materials in neural science, however, their exposure risks to the central nervous system (CNS) and toxicity concerns are also increased. The current studies of GO-induced neurotoxicity remain still ambiguous, let alone the mechanism of how complicated GO chemistry affects its biological behavior with neural cells. In this study, we characterized the commercially available GO in detail and investigated its biological adverse effects using cultured SH-SY5Y cells. We found that ultrasonic processing in medium changed the oxidation status and surface reactivity on the planar surface of GO due to its hydration activity, causing lipid peroxidation and cell membrane damage. Subsequently, ROS-disrupted mitochondrial homeostasis, resulting from the activation of NOX2 signaling, was observed following GO internalization. The autophagy-lysosomal network was initiated as a defensive reaction to obliterate oxidative damaged mitochondria and foreign nanomaterials, which was ineffective due to reduced lysosomal degradation capacity. These sequential cellular responses exacerbated mitochondrial stress, leading to apoptotic cell death. These data highlight the importance of the structure-related activity of GO on its biological properties and provide an in-depth understanding of how GO-derived cellular redox signaling induces mitochondrion-related cascades that modulate cell functionality and survival.

Objective:To explore the mediating effect of perceived organizational support on the relationship between personality traits and perceived self-efficacy of male nurses.Methods:A total of 766 male nurses from 20 level-A general hospitals in Shandong province were selected by convenience sampling method in December 2020. The general status questionnaire, the simplified version of Big Five Personality Inventory, the Perceived Organizational Support Scale and the General Self-efficacy Scale were used to investigate them.Results:The total score and average item score of 766 male nurses' sense of organizational support was 44.05±9.31, 3.38±0.72, and the total score and average item score of general self-efficacy was 26.19±5.65, 2.62±0.57. In 766 male nurses, perceived organizational support had a partial mediating effect on neuroticism and openness, with effect values of 21.71% and 10.19%, respectively. In addition, perceived organizational support had a complete mediating effect on conscientiousness and self-efficacy.Conclusions:The organizational support and self-efficacy of 766 male nurses were above average, and organizational support played a mediating role in the relationship between neuroticism, openness, conscientiousness and general self-efficacy.Nursing managers should give more organizational support to male nurses to change the influence of neuroticism, responsibility, agreeableness and open personality traits on self-efficacy, so as to improve the level of self-efficacy of male nurses.

Due to its unique physical structure and chemical properties, graphene family nanomaterials (GFNs) and derived commodities have been widely used in commercial products, particularly biomedical applications, which has significantly increased the risk of human exposure. There exists significant evidence that GFNs are accumulated in a number of tissues and organs through different exposure pathways, and further cause toxicity manifested as lesions or functional impairment. Moreover, GFNs can be internalized by varing cell types and induce cytoskeletal disorders, organelle dysfunction, and interact directly with biological macromolecules such as DNA, mRNA and proteins, ultimately resulting in greater rates of cell apoptosis, necrosis and autophagic cell death. The toxicological effect of GFN is closely related to its lateral size, surface structure, functionalization, and propensity to adsorb proteins. Using major data published over the past four years, this review presents and summarizes state of current understanding of GFN toxicology and identifies current deficiencies and challenges. This review aims to help improve evaluation of the biocompatibility of GFNs and provides theoretical guidance for their safe application.

Objective@#To investigate the status of knowledge about acquired immune deficiency syndrome(AIDS) among college freshmen in Jiangsu Province, and to analyze the influences of AIDS-related knowledge on their sexual attitudes and behaviors.@*Methods@#A total of 8 633 freshmen from 20 colleges and universities in Jiangsu Province were enrolled by multi-stage stratified sampling. The questionnaire for young students about the eight items of AIDS basic knowledge were used to investigate the AIDS-related knowledge, sexual attitudes and behaviors. Multivariate Logistic regression model was used to analyze the influencing factors of the AIDS-related knowledge and to adjust the influences of AIDS-related knowledge on sexual attitudes and behaviors.@*Results@#The overall qualified rate of AIDS-related knowledge among college freshmen in Jiangsu Province was 87.6% and the qualified rate of 8 items were between 59.8% and 98.3%. The types of schools, nationality, mother s education level and whether only child or not were identified as independent factors for qualified rate of AIDS-related knowledge(P<0.05). The awareness of AIDS-related knowledge had significant impacts on the sexual attitudes and behaviors of college freshmen. Students with insufficient knowledge were more likely to approve premarital sexual behaviors(OR=1.31, 95%CI=1.11-1.63), willing to use condoms consistently(OR=1.67, 95%CI=1.43-1.92) and to accept the HIV tests(OR=4.54, 95%CI=3.13-6.52). Students with unqualified knowledge were more likely to have sexual behavior(OR=1.89, 95%CI=1.42-2.49), while those with sexual experiences and insufficient AIDS knowledge were more likely to use condoms consistently(OR=2.13, 95%CI=1.22-3.78).@*Conclusion@#The education on AIDS-related knowledge for teenagers was helpful to construct correct sexual concepts and develop healthy sexual behaviors. However, the AIDS-related knowledge of college freshmen in Jiangsu Province is not sufficient and needed to improve.

@#ObjectiveTo investigate the language cortex organization characteristics of native Chinese. Methods20 patients who underwent language mapping via intraoperative direct cortical electrical stimulation (ioDCES) under awake anaesthesia for glioma in dominant hemisphere were analyzed retrospectively. Results16 patients were identified at least one language site, 3 patients located in the frontal and 1 patient in the temporal lobe. The language sites mostly located in the perisylvian region. The frontal language sites conformed to traditional Broca's areas, but the superior temporal gyrus contained much more language sites than the middle temporal gyrus.ConclusionHigh individual variability in language organization indicates a need for revision of the classical model of language localization. Because of the samples were too small, our current dates can't fully reflect language cortex organization characteristics of native Chinese.
RESUMO
Objective; To investigate the immunolocalization and significance of Notch-2 expression in the process of dental pulp repair after injury. Methods: An experimental animal model of injury-induced pulpitis was established to observe the time-sequenced alteration of the expression of Notch-2. Results: Three days post-operation, weak positive staining of Notch-2 was observed in pulp mesenchyme cells and pulp fibroblasts but not in vascular endothelial cells or odontoblasts. Five days post-operation, strong Notch-2 reactivity was found in subodontoblasts as well as newly bom capillary endothelial cells. Seven days after cavity preparation, Notch-2 staining became weaker in pulp mesenchyme cells and capillary endothelial cells, but stronger positive staining was found in odontoblasts. Two weeks post-operation, weak Notch-2 staining was seen in pulp mesenchyme cells and subodontoblastic layer cells and was absent from odontoblasts. Notch-2 immunoreactivity was completely absent in intact rat dental pulp. Conclusion: Notch-2 is strikingly up-regulated in dental pulp mesenchyme cells in the early days after dental injury and then shows progressively up-regulation in odontoblasts. Properly regulated activation of Notch signaling pathway is important for controlling cell fate and maintaining the correct balance among cell proliferation, differentiation and apoptosis during dental pulp repair process.

There were 6 grades, grade 0 was taken as meaningless language or auditory understanding ability, and grade 5 as extremely few differentiable language disorders, the patients could feel some difficulties subjectively, but the hearer was uncertain to obviously detect.MAIN OUTCOME MEASURES: Association between aphasia types and lesion sites; Grading of aphasia severity. Aphasia not caused by the involvement of language centers: Of the 1 198 patients with cerebral infarction, the Broca area in 5 cases and Wernicke area in 4 cases were involved, and did not cause aphasia syndrome in the Western battery aphasia showed that 83 cases had Broca aphasia, 48 cases Wernicke aphasia, 58 cases complete aphasia, 12 cases conduction aphasia, 36 cases transcortical motor aphasia, 17 cases transcortical sensory aphasia, 19 cases transcortical mixed aphasia and 52 cases nominal aphasia. The lesions located at typical language center in 240 cases and at nonaphasia examination severity grading standard: It was grade 0 in 84 cases, grade 1 in 79 cases, grade 2 in 77 cases, grade 3 in 63 cases and grade 4 in 22 cases, and the typical language centers were involved in most of the patients of grade 0 and grade 1.CONCLUSION: The association between types and lesion sites of most aphasia are in accordance with the typical aphasia mode, but it was not completely accordant in a few aphasias, the lesion of non-language centers can also cause aphasia, and the aphasia is greatly severe in the patients with the lesion site of language centers.
