Objective:To study the clinicopathologic characteristic of the primary extranodular non-Hodgkin's lymphoma in head and neck.Method:Clinical manifestation and the characteristic of clinicopathology of 216 extranodular non-Hodgkin's lymphoma patients in head and neck were analyzed retrospectively.Result:The age of thirty-one to sixty and seventy-one to eighty years old were more common age range in the group of patients. Nasal cavity was the most commonly primary involved site(95 cases, 44.0% ) , secondly was tonsil ( 47 cases, 21.8%). The most common histologic subtype was NK/T cell lymphoma, which accounted for 49.5%(107 cases)of cases, secondly was diffuse large B cell lymphoma (DLBCL, 58 cases, 26.7%). The most common histologic subtype in different swtach groups respectively is: NK/T cell lymphoma in nasal cavity(74 cases,77.9%), DLBCL in paranasal sinus(6 cases,50.0%), DLBCL in tonsil(27 cases,57.4%),NK/T cell lymphoma in nasopharynx(17 cases,44.7%), and DLBCL in lingual root(5 cases,45.4%).Conclusion:We conclude that primary extranodular non-Hodgkin's lymphoma is common in head and neck patients. There is characteristic in age, primary involved site and histologic subtype, which is helpful to understand these characteristic for pathologic diagnosis.

OBJECTIVE: To analysis the causes and treatment for postnasal drip syndrome. METHOD: One hundred patients were tested by routine examination of otolaryngology, nasal endoscopy, fiberoptic laryngoscopy and nasal sinuses CT. Choice allergen test and nasopharynx X-ray were taken based on the symptoms and signs. Patients were treated accordingly for different causes, such as flushing the nasal cavity by herbal liquid, using glucocorticoid locally, taking medicine of improving the sticky film cilium function, immunotherapeutic or operation. RESULT: The causes included chronic rhinitis 22 cases (22%), chronic sinusitis or nasal polyp 31 cases (31%), allergic rhinitis 28 cases (28%), adenoid vegetation 16 cases (16%), chronic nasopharyngitis 3 cases (3%). All patients were treated accordingly and total cure rate was 82% after 6 months follow up. CONCLUSION The causes of postnasal drip syndrome are complicated. It is critical to check the cause and chose adaptable therapy for good result.

Objective:To investigate the association between skin advanced glycation end products (AGEs) and carotid atherosclerosis (AS) in subjects with normal glucose regulation (NGR).Methods:This was a cross-sectional study. Data from the Health Management Center of the First Affiliated Hospital of University of Science and Technology between January 2019 to June 2019 were collected. A total of 902 NGR subjects aged 40-79 were enrolled and categorized into control group (530 cases), carotid intima-media thickness (IMT) thickening group (150 cases), and carotid atherosclerosis plaque group (222 cases) based on the carotid ultrasound results. Data as follows were collected, gender, age, blood pressure, body mass index (BMI), triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), fasting blood glucose (FPG), glycosylated hemoglobin (HbA 1c) and skin AGEs. Comparison via ANOVA analysis were carried out among the 3 groups. Logistic regression analysis was used to screen the independent influencing factors of carotid atherosclerosis plaque. Spearman correlation analysis was used to evaluate the correlation between AGEs and other parameters, and receiver operating characteristic (ROC) curve was used to evaluate the efficiency of skin AGEs in predicting carotid atherosclerosis plaque in NGR subjects. Results:Among the control group, IMT thickening group and carotid atherosclerosis plaque group, gender, age, systolic blood pressure (SBP), diastolic blood pressure (DBP), TC, LDL-C, FPG, HbA 1c, AGEs were significantly different (all P<0.05). Compared with IMT thickening group, the age, SBP and AGEs of carotid atherosclerotic plaque group were higher [55 (50, 60) vs 53 (49, 56) year; 132 (122, 141) vs 126 (115, 142) mmHg(1 mmHg=0.133 kPa); 74 (67, 81) vs 72 (67, 78) AU] (all P<0.001); compared with the control group, age, LDL-C, HbA 1c and AGEs of IMT thickening group were higher [53 (49, 56) vs 48 (45, 52) year; (2.8±0.7) vs (2.7±0.7) mmol/L; 5.4% (5.2, 5.6)% vs 5.4% (5.1, 5.6)%; 72 (67, 78) vs 70 (66, 76)] (all P<0.05). Age ( OR=1.179, 95% CI: 1.107-1.255), SBP ( OR=1.045, 95% CI: 1.013-1.077), LDL-C ( OR=2.028, 95% CI: 1.036-3.969), AGEs ( OR=1.049, 95% CI: 1.000-1.100) were independent influencing factors of carotid atherosclerotic plaque in population with normal glucose regulated (all P<0.05). AGEs was positively correlated with age, HbA 1c and carotid atherosclerosis plaque ( r=0.407, 0.092, 0.172) (all P<0.01). The area under the ROC curve of skin AGEs for identifying carotid atherosclerotic plaque in NGR population was 0.650 (95% CI 0.601-0.698), the best cutoff value was 70.5, the sensitivity was 65.8%, and the specificity was 56.9%. Conclusion:Skin AGEs level is closely associated with the occurrence of carotid atherosclerosis in NGR subjects.

Objective To investigate the pathomorphological features of mucosa-associated lymphoid tissue(MALT)lymphoma of the lacrimal gland and the expression and significance of BCL10 and MALT1 in tumor tissues.Methods Diseased lacrimal gland tissue specimens from 19 patients with lacrimal gland MALT lymphoma(19 eyes,including nine right eyes and ten left eyes)were selected as the experimental group,and normal lacrimal gland tissue specimens from eight patients with orbital content removal(eight eyes,including three right eyes and five left eyes)were selected as the control group.Hematoxylin-eosin(HE)staining was performed to observe the mor-phological characteristics of the lacrimal gland tissues,and immunohistochemical(IHC)staining was performed to observe the expression of BCL10 and MALT1 in the lacrimal gland tissues.Results In the experimental group,marginal B cells,monocyte-like tumor cells,small lymphocyte-like tumor cells,and plasma cell-like tumor cells appeared in the marginal zone.Large cells were occasionally distri-buted among these cells.The tumor cells invaded the lymphoid follicles and epithelium,destroyed normal tissue structure,and formed follicular colonization and lymphoepithelial lesions.The positive expression area of BCL10 and MALT1 in the experimental group was sig-nificantly larger than that in the control group(Z=-2.177,P=0.029;t=3.237,P=0.003).Conclusion Lacrimal gland MALT lymphoma shows pathological changes in diffusely distributed marginal B cells and tumor cells with diverse morphology,acquired lymphoid follicles,and scattered distribution of large cells.This may be related to apoptosis blockage caused by the upregulation of BCL10 and MALT1 expression.

【Objective】 To investigate the effect of leukocyte-depleted suspended red blood cells (lds-RBCs) storaged for different time on blood transfusion effect of patients with hematologic diseases and malignant tumors, as well as to evaluate the storage quality of lds-RBCs in blood stations. 【Methods】 Seven hospitals (4 tertiary-A hospitals and 3 secondary-A hospitals), applying for blood from our blood center, were selected. Blood transfusion cases (medical record) and related data (indicators) of patients with blood diseases and malignant tumors in those hospitals from December 2018 to May 2019 were collected, including disease diagnosis (type) before transfusion, demographic characteristics, date of solo transfusion of lds-RBCs, units of lds-RBCs [(1~2)U/bag, 1 U=200 mL whole blood], different storage duration (1~5 weeks) (bar code), and hemoglobin (Hb) 48 h before and after transfusion. The efficacy of lds-RBCs (storaged for different time) transfusion in patients with hematologic diseases and malignant tumors was evaluated by statistical analysis. 【Results】 A total of 3 557 patients with hematologic diseases and malignant tumors were enrolled in this study. No significant changes were noticed in transfusion efficacy by blood transfusion unit, gender and previous transfusion history (P > 0.05). The effective rate of lds-RBCs in patients with blood diseases and malignant tumors, stratified by storage duration, i. e. storaged for >1~2 weeks, >2~3 weeks, >3~4 weeks and more than >4~5 weeks, was 78.77% vs 77.68% vs 75.06% vs 70.37%, and 79.32% vs 76.73% vs 72.79% vs 67.65%, respectively(P<0.05), with lds-RBCs of 4-5 storage weeks presenting the lowest transfusion efficacy in both groups of patients. 【Conclusion】 The storage time of most lds-RBCs supplied by our center is moren than 3 weeks, and the transfusion effect of lds-RBCs stored for 5 weeks needs further observation. In order to ensure and improve the efficacy of blood transfusion, evidence-based medicine and information management are needed to help the clinical gasp the advantageous time of blood products and shorten the storage-to-transfusion time of red blood cells.
