Objective To investigate the clinical presentations,pathological features and radiographic appearance of intraosseous well differentiated osteosarcoma and its differential diagnosis.Methods One case of intraosseous well differentiated osteosarcoma was analyzed,and the clinical presentations,radiographic appearances and histological features of intraosseous well differentiated osteosarcoma were summaried on the basis of reviewing the related literatures.Results The age of onset of this disease was mostly within a range of 30~40 years.The scopes of this lesion were almost large,and the metaphyses of the long bone were the major targets of the lesions,especially the inferior extremity of femur and superior extremity of tibia.The tumor appeared as destruction of combined with bony restoration within the medullary cavity.The tumor was composed of fiber and bony tissue which had well differentiated cells with rarely nuclear division.About 50 % of patients was diagnosed incorrectly as benign lesion at first.Conclusion It is difficult to early diagnose intraosseous well differentiated osteosarcoma,but comprehending its pathological,immunohistological features and combining clinic will benefit for the correct diagnosis.

Objective To analyze the long-term results of rituximab combined with whole brain radiotherapy and 3-dimentional conformal radiotherapy (3D-CRT) in treatment of patients with primary central nervous system lymphoma (PCNSL). Methods 23 postoperative patients younger than 60 years old were treated. Whole brain radiotherapy with dose of 32.4 Gy were performed and lesions were followed by 3D-CRT with dose of 18 Gy.A dose of rituximab (375 mg/m2) was infused on day 1 (once a week for six weeks).The overall survival was analyzed by using Kaplan-Meier.Results 19 patients(82.6 ％) was complete remission 3 patients (13.0 ％) was part remission,14 patients (60.9 ％) was progression-free survival was 26 months (17-34 months). The overall survival was 40 months (29-55 months). Toxicity was moderate without grade 3-4 neurotoxicity toxic events. Conclusions Radiotherapy (whole brain radiotherapy with sequential 3D-CRT)combined with rituximab seems to yield substantial long-term survival with moderate toxicity for the treatment of the younger patients with PCNSL.

Objective: To analyze the research status, hotspots and frontier progress of hypertension in children in English and Chinese literature, so as to provide reference for the early prevention of hypertension in children. Methods: The Web of Science core collection database and CNKI database were searched to collect the literature related to the study of hypertension in children from 2000 to 2021, and the CiteSpace 5.8.R3 and VOSviewer 1.6.18 visualization tools were used to analyze the literature characteristics including publications, authors, regions, institutional cooperation, research hotspots and frontiers. Results: A total of 22 687 English studies and 4 440 Chinese studies were finally included. According to the analysis results, the number of articles published on hypertension in children was on the rise. The published English articles were mainly University of Toronto and University of Colorado. The main publishing institution of Chinese articles was the First Affiliated Hospital of Peking University. The United States and China took the lead in the number of core journals published in the field of hypertension in children, the United States ranked first in terms of the influence of publications. Keyword co occurrence analysis showed that the high frequency keywords in the English literature included prevalence, risk, obesity, risk factor, body mass index, insulin resistance, overweight, metabolic syndrome, cardiovascular disease and mortality. Chinese high frequency keywords in the literature include obesity, risk factors, adiposis, influencing factors, overweight, prevalence, diabetes, treatment, health education and body mass index. The analysis of keywords showed that 25 burst terms were obtained separately in English and Chinese literature. Conclusion In recent years, the research interest on hypertension in children continues to grow and keeps updated, with the research scope expanding significantly, regarding obesity, diabetes and cardiovascular diseases.

Purpose: From the perspective of positive psychology, our study aimed to explore depressive symptomsand psychological well-being among Chinese nurses, as well as analyze the impacts of characterstrengths, self-efficacy and social support on the mental health of nurses. Methods: A cross-sectional and descriptive design using five self-reported questionnaires was used toinvestigate a cohort of 4238 nurses during 2018. A structural equation modeling analysis was used toverify a hypothetical model linking character strengths, self-efficacy, social support, depressive symptoms,and psychological well-being. Results: The prevalence of depression among this cohort of Chinese nurses was 58.1%. The mean scoresfor caring, inquisitiveness, and self-control were 19.93 (SD = 2.82), 15.94 (SD = 3.00), and 16.34(SD = 2.95), respectively. The hypothesized model was a good fit of the data (x2/df = 1.77, p = .183, rootmean square error of approximation = 0.04, goodness of fit index = 1.00, comparative fit index = 1.00,TuckereLewis index = 1.00). Except for the path from self-control to depression, the other hypotheticalpaths investigated were statistically significant. Conclusion Character strengths were directly and positively associated with psychological well-being.Inquisitiveness was the strongest direct protective factor for depression. In addition, characterstrengths indirectly alleviated depression and increased psychological well-being through mediatingvariables of social support and self-efficacy. This study should alert nurse managers that more attentionshould be paid to the character strengths and mental health of nurses. This study provides evidence forinterventions based on character strengths as a management strategy to support the mental health ofnurses.
