Trousseau syndrome is a cancer-associated hypercoagulative state leading to venous or arterial thromboembolic events. Cerebral infarction is the most common result of arterial embolism and the pathogenesis is complicated, mainly associated with hypercoagulation and non-bacterial thrombotic endocarditis. On magnetic resonance imaging, multiple lesions are dispersed in more than two territories of the brain, often simultaneously involving the bilateral anterior and posterior circulation. Elevated plasma levels of D-dimer and fibrinogen degradation products may be seen in these patients. There are high rates of short-term recurrence of stroke and sudden death, highlighting the need for early recognition and appropriate treatment of Trousseau syndrome-associated cerebral infarction.Large clostridial toxins (LCTs) are a family of bacterial exotoxins that infiltrate and destroy target cells. Members of the LCT family include Clostridioides difficile toxins TcdA and TcdB, Paeniclostridium sordellii toxins TcsL and TcsH, Clostridium novyi toxin TcnA, and Clostridium perfringens toxin TpeL. Since the 19th century, LCT-secreting bacteria have been isolated from the blood, organs, and wounds of diseased individuals, and LCTs have been implicated as the primary virulence factors in a variety of infections, including C. difficile infection and some cases of wound-associated gas gangrene. Clostridia express and secrete LCTs in response to various physiological signals. LCTs invade host cells by binding specific cell surface receptors, ultimately leading to internalization into acidified vesicles. Acidic pH promotes conformational changes within LCTs, which culminates in translocation of the N-terminal glycosyltransferase and cysteine protease domain across the endosomal membrane and into the cytosol, leading first to cytopathic effects and later to cytotoxic effects. The focus of this review is on the role of LCTs in infection and disease, the mechanism of LCT intoxication, with emphasis on recent structural work and toxin subtyping analysis, and the genomic discovery and characterization of LCT homologues. We provide a comprehensive review of these topics and offer our perspective on emerging questions and future research directions for this enigmatic family of toxins.Background Chinese medicine (CM) has been widely used for women's health, including those with early breast cancer. Contemporary literature varies in descriptions of the CM syndromes that are critical for determining CM treatment options for breast cancer patients. However, the corresponding syndromes have not been standardized to align with the conventional medicine treatment stages. This review aimed to address this knowledge gap to enhance the quality and consistency of CM interventions for early breast cancer patients. Methods In total, eight Chinese and English language databases were searched, and textbooks and clinical care documents were gathered. Sources were classified according to five treatment stages preoperative, postoperative, chemotherapy, radiation therapy, and endocrine therapy. Descriptive statistics were used to examine the syndromes, and hierarchical cluster analysis was conducted to investigate clusters of signs and symptoms. Results The CM syndrome of dual deficiency of qi and Blood wasfrequently seen CM syndromes and cluster results have some similarities but some important distinctions. Clinical data are needed to confirm whether the syndromes described in contemporary literature reflect those seen in women with early breast cancer.Purpose Evaluate the clinical efficacy and safety of minimally invasive surgery (MIS) and open surgery in the treatment of neuroblastoma (NB) in children by a meta-analysis. Materials and Methods This is a meta-analysis. We searched for random or nonrandomized controlled study of MIS group and OPEN surgery group for the treatment of childhood NB included in PubMed, ClinicalTrials, EMBASE, and Cochrane library before January 31, 2020. Data extraction was performed in a standard format for the included studies, including tumor diameter, operation time, intraoperative bleeding, length of hospital stay (LOHS), complications, recurrence, and MYCN. Results Seven retrospective studies were finally included, with a total of 571 children, including 162 in MIS group and 409 in the OPEN surgery group. Compared with the OPEN surgery group, the MIS group had reduced intraoperative bleeding (mean difference [MD] = -12.72, 95% CI -24.84 to -0.61, P  .05). Conclusions Preliminary evidence indicates that the treatment of NB with MIS has the advantages of less intraoperative bleeding, shorter LOHS, and less postoperative recurrence compared with open surgery.Objective A preliminary investigation of the impact of a serotonergic agent (fluoxetine) on symptom profile and neural response in youths with disruptive behavior disorders (DBDs) and a history of trauma exposure. Methods There were three participant groups (i) Youths with DBDs and trauma exposure who received fluoxetine treatment for 8 weeks (n = 11); (ii) A matched group of youths with DBDs and trauma exposure who received routine regular follow-up in an outpatient clinic (n = 10); and (iii) Typically developing youths (n = 18). PI3K signaling pathway All participants conducted an expression processing functional magnetic resonance imaging task twice, 8 weeks apart (pretreatment and post-treatment for youths with DBDs). Results Youths with DBDs and trauma exposure who received fluoxetine treatment compared to the other two groups showed (i) significant improvement in externalizing, oppositional defiant disorder, irritability, anxiety-depression, and trauma-related symptoms; (ii) as a function of fearful expression intensity, significantly decreased amygdala response and increased recruitment of regions implicated in top-down attention control (insula cortex, inferior parietal lobule, and postcentral gyrus) and emotional regulation (ventromedial prefrontal cortex [vmPFC]); and (iii) correlation between DBD/irritability symptom improvement and increased activation of top-down attention control areas (inferior parietal lobule, insula cortex, and postcentral gyrus) and an emotion regulation area (vmPFC). Conclusions This study provides preliminary evidence that a serotonergic agent (fluoxetine) can reduce disruptive behavior and mood symptoms in youths with DBDs and trauma exposure and that this may be mediated by enhanced activation of top-down attention control and emotion regulation areas (inferior parietal lobule, insula cortex, and vmPFC).
