Objective:To compare the consistency of lymphoma multigene detection panels based on next-generation sequencing (NGS) with FISH detection of B-cell lymphoma gene rearrangement.Methods:From January 2019 to May 2023, fusion genes detected by lymphoma-related 413 genes that targeted capture sequencing of 489 B-cell lymphoma tissues embedded in paraffin were collected from Henan Cancer Hospital, and the results were compared with simultaneous FISH detection of four break/fusion genes: BCL2, BCL6, MYC, and CCND1. Consistency was defined as both methods yielding positive or negative results for the same sample. The relationship between fusion mutation abundance in NGS and the positivity rate of cells in FISH was also analyzed.Results:Kappa consistency analysis revealed high consistency between NGS and FISH in detecting the four B-cell lymphoma-related gene rearrangement ( P<0.001 for all) ; however, the detection rates of positive individuals differed for the four genes. Compared with FISH, NGS demonstrated a higher detection rate for BCL2 rearrangement, a lower detection rate for BCL6 and MYC rearrangement, and a similar detection rate for CCND1 rearrangement. No correlation was found between fusion mutation abundance in NGS and the positivity rate of cells in FISH. Conclusions:NGS and FISH detection of B-cell lymphoma gene rearrangement demonstrate overall good consistency. NGS is superior to FISH in detecting BCL2 rearrangement, inferior in detecting MYC rearrangement, and comparable in detecting CCND1 rearrangement.

Venous thromboembolism is a common comorbidity in neurosurgery department that can lead to life-threatening pulmonary embolism, endangering patient health. The unique characteristics of neurosurgical conditions often present a high risk of bleeding, which complicates the treatment of venous thrombosis. Although numerous observational studies and meta-analyses support the feasibility of initiating early anticoagulation prevention or treatment after hemorrhage stabilization in intracranial hemorrhagic conditions such as traumatic brain injury and cerebral hemorrhage, there is a lack of high-quality clinical research. As a result, neurosurgeons tend to adopt a conservative approach regarding pharmacological prophylaxis and anticoagulant treatment for venous thromboembolism. Key aspects such as the timing of prevention, monitoring, and discontinuation of treatment still require high-quality research to establish definitive guidelines.

With the intensify of aging population,accurate assessment of brain health becomes more and more important.Brain age can reflect brain health and cognitive function.Based on different algorithms,modal data and central datasets,imaging is helpful for predicting brain age.The progresses of imaging researches for predicting brain age were reviewed in this article.

With the aging population, the burden of diseases such as atrial fibrillation and venous thrombosis is gradually increasing. Anticoagulant therapy has a positive significance in preventing ischemic stroke, pulmonary embolism, and other related conditions in these patients. However, anticoagulant therapy can have the opposite effect on diseases caused by intracranial hemorrhage, such as falls in the elderly, cerebrovascular accidents, and car accidents. It is still difficult to determine whether and when to restart anticoagulation after cerebral hemorrhage. Although most studies have shown that restarting anticoagulant therapy can reduce stroke risk without significantly increasing bleeding risk, they are mostly based on observational studies, so more high-quality research is needed to guide clinical decision-making. This article reviews the research progress on restart anticoagulation, aiming to provide some assistance for clinical applications.

Objective:To explore the structural and functional alterations of related brain regions in patients after cardiopulmonary resuscitation (CPR) by brain magnetic resonance imaging (MRI).Methods:A single-center, observational, cross-sectional study design was used. Patients who had brain MRI scans during hospitalization between July 2020 and July 2021 in Emergency Department of the First Affiliated Hospital of Nanjing Medical University and had good neurologic outcomes were consecutive enrolled in this study. The healthy control (HC) group consisted of age- and sex-matched volunteers. The demographic and clinical data were recorded. The modified Rankin Scale (mRS) was used to check the recovery and degree of continued disabilities when patients performed MRI. Montreal cognitive assessment (MoCA) was used to assess cognitive functions. The analyses of voxel-based morphometry (VBM) and fractional amplitude of low-frequency fluctuation (fALFF) were conducted. After data preprocessing, comparison of gray matter volume (GMV) and fALFF values between the case group and HC group were carried out, and the information of different brain regions was obtained. Partial correlation analyses were performed to evaluate the correlation between the image parameters of different clusters and clinical parameters.Results:Totally 13 patients were enrolled in this study and 13 were in the HC group. All patients achieved good neurologic outcome; mRS was 3 in 1 case, 2 in 3 cases, and 1 in 5 cases during MEI examination. The case group showed significantly lower MoCA score compared with the HC group ( P<0.001). There were significantly decreased GMVs in the right inferior frontal gyrus, superior temporal gyrus, left superior temporal gyrus, and transverse temporal gyrus in the case group. The patients showed significantly decreased fALFF values in the left postcentral gyrus and precentral gyrus, while increased fALFF values in the right putamen than the HC group (voxel-level P<0.001 and cluster-level P<0.05 with GRF correction). In addition, mean fALFF value in the right putamen was negatively correlated with MoCA score in the case group ( r=-0.710, P=0.021). Conclusions:Patients after CPR may have GMVs and neuronal spontaneous activity changes in some brain regions, and VBM and fALFF methods can be used to objectively evaluate the impaired brain functional activity in patients after successful CPR.

Objective:To explore the effect of pediatric critical illness score (PCIS), pediatric risk of mortality Ⅲ score (PRISM Ⅲ), pediatric logistic organ dysfunction 2 (PELOD-2), pediatric sequential organ failure assessment (p-SOFA) score and Glasglow coma scale (GCS) in the prognosis evaluation of septic-associated encephalopathy (SAE).Methods:The data of children with SAE admitted to the Pediatric Intensive Care Unit (PICU), Guangdong Provincial People’s Hospital, Guangdong Academy of Medical Sciences from January 2010 to December 2020 were retrospectively analyzed. They were divided into the survival and death groups according to the clinical outcome on the 28th day after admission. The efficiency of PCIS, PRISM Ⅲ, PELOD-2, p-SOFA and GCS scores for predicting death were evaluated by the area under the ROC curve (AUC). The Hosmer-Lemeshow goodness-of-fit test assessed the calibration of each scoring system.Results:Up to 28 d after admission, 72 of 82 children with SAE survived and 10 died, with a mortality rate of 12.20%. Compared with the survival group, the death group had significantly lower GCS [7 (3, 12) vs. 12 (8, 14)] and PCIS scores [76 (64, 82) vs. 82 (78, 88)], and significantly higher PRISM Ⅲ [14 (12, 17) vs. 7 (3, 12)], PELOD-2 [8 (5, 13) vs. 4 (2, 7)] and p-SOFA scores [11 (5, 12) vs. 6 (3, 9)] ( P<0.05). The AUCs of PCIS, PRISM Ⅲ, PELOD-2, p-SOFA and GCS scores for predicting SAE prognosis were 0.773 ( P=0.012, AUC>0.7), 0.832 ( P=0.02, AUC>0.7), 0.767 ( P=0.014, AUC>0.7), 0.688 ( P=0.084, AUC<0.7), and 0.692 ( P=0.077,AUC<0.7), respectively. Hosmer-Lemeshow goodness-of-fit test showed that PCIS ( χ2=5.329, P=0.722) predicted the mortality and the actual mortality in the best fitting effect, while PRISM Ⅲ ( χ2=12.877, P=0.177), PELOD-2 ( χ2=8.487, P=0.205), p-SOFA ( χ2=9.048, P=0.338) and GCS ( χ2=3.780, P=0.848) had poor fitting effect. Conclusions:The PCIS, PRISM Ⅲ and PELOD-2 scores have good predictive ability assessing the prognosis of children with SAE, while the PCIS score can more accurately evaluate the fitting effect of SAE prognosis prediction.

Gastroesophageal reflux disease is a series of intraesophageal and/or extraesophageal symptoms caused by the reflux of gastric contents into the esophagus because of abnormal structure and function of gastroesophageal junction. Acid suppression therapy is the preferred treatment, but most patients with gastroesophageal reflux disease have poor symptom control or excessive dose for drug control, resulting in low quality of life. With the renewal of endoscopic equipment, endoscopic adjuvant therapy is attracting the attention of clinical physicians and patients owing to minimal trauma, rapid recovery, obvious symptom control, and few complications. This paper reviews endoscopic adjuvant therapy.

Objective:The study seeks to explore the factors influencing the psychological status and sleep quality of medical workers amid the ongoing COVID-19 pandemic, in order to provide data sources and theoretical basis for the development of relevant psychological intervention programs.Methods:Employing the convenience sampling method, general information questionnaire (age, gender, marital status, educational background, job status, etc.), Generalized Anxiety Disorder-7 and Patient Health Questionnaire, epidemic stress index scale, and sleep quality questionnaire were distributed to medical staff between February 18 and April 3, 2020, using the PEM mental health care platform of by ZhongShengKaiXin for medical staff issued. Descriptive, single factor, and correlation analyses, as well as multiple linear regression analysis were used to analyze the data.Results:Overall, 24, 845 questionnaires were collected from 23 provinces, of which 24, 687 were valid, with a recovery rate of 99.36%. The findings showed that the proportion of medical personnel with symptoms of anxiety and depression was 50.58% and 51.37%, respectively; 16.11% had poor or very poor anti-stress ability; and 71.78% reported poor or very poor sleep quality. There was a positive correlation between anxiety, depression, anti-stress ability, and sleep quality ( P<0.05). Anxiety was positively correlated with depression, stress tolerance, and sleep quality( r=0.787, 0.667, and 0.486, all P<0.001); depression was positively correlated with stress tolerance and sleep quality ( r=0.709 and 0.586, both P<0.001); and stress tolerance was positively correlated with sleep quality ( r=0.452, P<0.001). Multiple linear regression analysis results showed that age, gender, marital status, educational background, professional title, job status, and participation influenced the anxiety levels of medical personnel in the backdrop of the pandemic ( P<0.001). Depression levels of medical staff were influenced by gender, educational background, job position, and participation ( P<0.001), while gender, marital status, educational background, job position, and participation influenced the stress tolerance levels ( P<0.001). The sleep quality of medical workers was influenced by age, gender, job position, participation in the fight against the pandemic, and professional title ( P<0.001). Conclusions:Amid the ongoing COVID-19 pandemic, medical staff reported poor mental health status and sleep quality, which can be attributed to diverse factors. The research findings can be useful for assisting medical staff to strengthen their self-cognition, while also providing certain psychological counseling data and theoretical basis for management departments.
