In this paper,we analyzed one case of primary multifocal extranodal non-Hodgkin's lymphoma and reviewed the related literatures.We investigated the clinical data of this case with primary multifocal extranodal lymphoma and retrospected the related references.The key words,primary extranodal lymphoma and multifocal,were used to search Pubmed and Wanfang Database,and finally only three cases were found.The 68-yea-old woman was confirmatively diagnosed as primary multifocal extranodal B cell non-Hodgkin's lymphoma.The positron emission tomography/computed tomography (PET/CT) scan showed multiple hypermetabolic lesions in the left humerus,both kidneys and ileum.The confirmative diagnosis was based on clinical manifestations and serological tests,imaging features of CT and PET/CT,and especially on the histopathological and immunohistochemical studies.After one cycle chemotherapy (rituximab,Vincristine and prednisone) and another cycle (rituximab,Vincristine,cyclophosphamide and prednisone),a repeat PET/CT scan showed a complete metabolic resolution of the lesions in the kidneys and ileum,and a partial metabolic resolution of the left humerus.After four cycles of chemotherapy,there were new extensive involvements of the right supraclavicular and intrapulmonary lymph nodes,bilateral pleural and pericardium,and the patient gave up chemotherapy.This case demonstrated the imaging findings of an uncommon primary multifocal extranodal lymphoma in left humerus,both kidneys and ileum,and highlighted the usefulness of CT and PET/CT scan in identifying the extent of disease involvement,in guiding a biopsy,and in assessing the treatment response of lymphoma.It is essential to differentiate between primary multifocal extranodal lymphoma and lymphoma extensive metastases.

Objective:To study the inductive effect of recombinant MUC1-MBP fusion protein combined with R848 on the immune activity of T cells in the mice,and to provide experimental basis for searching the suitable adjuvants of recombinant MUC1-MBP fusion protein.Methods:A total of 21 C57BL/6 mice were randomly divided into control group(treat with normal saline),MUC1-MBP+R848 group (treated with MUC1-MBP+R848),and MUC1-MBP+baillus calmette guerin(BCG) group(treated with MUC1-MBP+BCG)(n=7).After immunized for 4-7 d,the spleen tissue was taken and the spleen indexes of the mice in various groups were measured;the stimmulus index(SI) of the mice was detected by lymphocyte proliferation response;the levels of tumor necrosis factor-γ(TNF-γ) and interleukin-4(IL-4) were detected by ELISA method;the proprotions of T lymphocyte subsets in spleen cells were analyzed by flow cytometry.Results:Compared with control group,the spleen indexes,SI,and TNF-γ levels of the mice in MUC1-MBP+ R848 and MUC1-MBP+BCG groups were significantly increased (P<0.05 or P<0.01);the indexes metioned above of the mice in MUC1-MBP+ R848 were higher than those in MUC1-MBP+BCG group;the IL-4 levels had no significant difference(P>0.05).Compared with control group,the proprotions of CD3+T,CD4+T,and CD8+ T cells of the mice in MUC1-MBP+ R848 group and MUC1-MBP+BCG group were significantly increased(P<0.05 or P<0.01).Conclusion:Both MUC1-MBP fusion protein combined with R848 and BCG can induce the Th1 type of immune activity in the mice,and R848 is the potential candidate adjuvant for MUC1-MBP.

Objective To strengthen the understanding of granulocytic sarcomas(GS)by investigating the clinical characteristics of GS of spine. Methods The clinical data of 2 GS patients were retrospectively analyzed, and the related literature was reviewed. Results Because of the double lower limbs numbness, the 2 GS patients came to orthopedics department of the 306th Hospital of PLA. Magnetic resonance imaging (MRI) of the 2 patients showed an epidural mass located at the 9th-11th and 2nd-4th thoracic levels. Their histopathological examination and immunohistochemistry revealed GS.For example 1,she was diagnosed with acute promyelocytic leukemia(APL)and has been morphologic complete commission(CR) from 1995 to 2015. Chemotherapy and all-trans retinoic acid (ATRA) were performed after extramedullary relapse in thoracic spine,breast,ovary,sternum bone and lymph nodes.So far,the patient is still in follow-up.For example 2,he was diagnosed as isolated GS by morphology, immune phenotype, chromosome and gene examinations. Because he refused chemotherapy, radiotherapy was performed after surgical intervention. So far, he is loss of follow-up. Conclusions Spinal epidural of GS is rare. Surgery can reduce or remove nerve compression symptoms, and help clear diagnosis. The current recommended treatment regimen in patients presenting with isolated GS or GS presenting concomitantly with AML is conventional AML-type chemotherapeutic protocols. The differences in prognosis of GS patients may be partially attributed to different characteristics of patient.

Objective:To investigate the correlation and predictive value of fibrinogen-to-albumin ratio (FAR) and clinical outcomes after intravenous thrombolysis in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke received intravenous thrombolysis treatment at Fuyang People's Hospital from November 2019 to August 2022 were retrospectively included. Their clinical, imaging, and laboratory data were collected. After 3 months of onset, a modified Rankin Scale was used for clinical outcome evaluation and a score >2 were defined as poor outcome. Multivariate logistic regression analysis was used to determine the correlation between FAR and poor outcome. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of FAR on adverse outcomes after intravenous thrombolysis in patients with acute ischemic stroke. Results:A total of 162 patients were included. There were 114 patients (70.4%) in the good outcome group and 48 (29.6%) in the poor outcome group. Univariate analysis showed that the baseline National Institutes of Health Stroke Scale (NIHSS) score, fasting blood glucose, fibrinogen, and FAR in the poor outcome group were significantly higher than those in the good outcome group, while the serum albumin was significantly lower than that of the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that the baseline NIHSS score (odds ratio [ OR] 1.176, 95% confidence interval [ CI] 1.082-1.227; P<0.001), fasting blood glucose ( OR 1.206, 95% CI 1.018-1.430; P=0.030), and FAR ( OR 1.448, 95% CI 1.449-1.824; P=0.002) were the independent risk factors for poor outcome. The ROC curve analysis showed that the area under the curve of FAR for predicting poor outcomes was 0.706 (95% CI 0.616-0.796). When the FAR cutoff value was 8.06, the sensitivity and specificity were 66.7% and 78.2%, respectively. Conclusion:There is a significant correlation between FAR and outcomes after intravenous thrombolysis therapy in patients with acute ischemic stroke. Higher FAR has certain predictive value for poor outcomes of patients.
