Objective To clarify clinical and morphological features and immunophenotype and Epstain-Barr virus infection of neoplastic cell rich Hodgkin's lymphoma (NCRHL)and to further improve our knowledge and pathological diagnosis for NCRHL. Methods 10 cases of NCRHL were analyzed for clinical features, morphology, immunophenotype, Epstein-Barr virus infection using routine eosin and haematoxylin stain, immunohistochemistry, Epstain-Barr virus encoded small RNA (EBER) in situ hybridization and combining clinical data. Results (1)NCRHL were more common in young people. The median age of the patients was 25.5 years old. The ratio of male to female was 1:2.3. Superficial lymph nodes were most frequently involved. Masses of mediastinum were seen commonly. Clinical manifestation of the patients included B symptom (6 cases), pruitus (5 cases) and anemia (1 case). (2)Architecture of lymph nodes were effected. Necrosis was seen in some cases. There were more tumor cells in NCRHL than that in the classical Hodgkin's lymphoma. The tumor cells were distributed in piece or patch or diffuse. The morphology of neoplastic cells was wore variable including Hodgkin-like cells, lacunar cell-like, mummy cell-like and anaplastic large cell-like, singular nucleated cells, and multinucleated giant cell-like cells. Numerous neutrophils and eosinophils were present in a few cases. Focal sheet, necrosis granulomatosis-like and diffuse growth pattern were found in NCRHL. (3)All of the cases were positive for CD30 and PAX-5.2/10 (20%) cases were CD15 positive. LCA, CD20 and CD3 were negative. (4)EBER was not detected in all 6 tested cases. (5)Follow up data was obtained in 8/10 cases, in which one patient was dead, one case relapsed in half a year,and the other 6 cases reached complete regression. Conclusion NRCHL is characterized mainly by neoplastic cell rich morphologically and focal sheet, necrosis granulomatosis-like and diffuse growth pattern.EBER was not detected in this tumor. Some cases have aggressive clinic process with a unfavourable prognosis. New treatment regimen should be explored.

OBJECTIVETo study the clinicopathologic features and pathologic diagnosis and differential diagnosis of angioimmunoblastic T-cell lymphoma with HRS-like cells.
METHODSSix cases of angioimmunoblastic T-cell lymphoma with HRS-like cells were examined histologically and immunohistochemically (EliVision method) and in-situ hybridization for Epstein-Barr virus-encoded RNA (EBER), and the literature was reviewed.
RESULTSThe cytologic and microscopic features of these imprints and lymph node samples showed a heterogeneous population of hematolymphoid cells, including small to intermediate lymphoid cells, immunoblasts, plasma cells, dendritic cells, and eosinophils, as well as small vessels that were surrounded by some of the abnormal cells. The neoplastic T-cells expressed CD3 and CD5 and partly positive for CD10 and bcl-6, CD21 showed expanded and irregular follicular dendritic cell (FDC) meshworks that surrounding the high HEV. The HRS-like cells were positive for MUM-1 and Ki-67, variable intensity positive for CD30, CD20, and PAX-5, but negative for CD15. EBV-positive cells included HRS-like cells and small to large-sized neoplastic T-cells, which formed small clusters or scattering in the background of the disease.
CONCLUSIONSThe clinical course of angioimmunoblastic T-cell lymphoma with HRS-like cells is aggressive. Which present with histomorphology overlap with classical Hodgkin lymphoma (CHL), similar to CHL in EBER and immunophenotype, however, it is easy to misdiagnosis as HL. Thus, angioimmunoblastic T-cell lymphoma pathology diagnosis should comprehensive analysis of different kinds of materials, including clinical features, and histological structure, and EBER, and immunophenotype, and gene rearrangement.

Objective:
To investigate the clinicopathologic characteristics of neoplastic cell-rich mixed cellularity classical Hodgkin lymphoma(MCCHL-R) and to compare the prognosis with typical mixed cellularity classic Hodgkin lymphoma(MCCHL).
Methods:
Fifty-four patients with MCCHL-R(the tumor cells >10%) and 65 patients with typical MCCHL identified from 1 721 Hodgkin lymphomas were reviewed to compare the clinicopathological characteristics including morphologic and immunophenotypic features, EBV infection status, clinical therapy and overall survival.
Results:
The median age of the patients of MCCHL-R was 28.5 years(range: 9-76 years, male∶female=1.6∶1.0). Twenty-seven patients(50.0%) had B symptoms. Most patients had cervical lymph node involvement(81.5%, 44/54). Mediastinum and spleen involvement were seen in 69.2%(36/54) and 24.1%(13/54), respectively. Extranodal non-lymphoid organ involvement was seen in 41.3%(19/46) cases. Morphologically, lymph node architectures were effaced at various degree with large neoplastic cells of variable morphology, including Hodgkin/Reed-Sternberg(H/RS) cells and anaplastic large cells. There were abundant background heterogeneous admixtures of non-neoplastic inflammatory and accessory cells that were predominant mature small lymphocytes. All tumors were positive for CD30 and weakly positive for PAX5. Epstein-Barr encoded RNA(EBER)detectable by in situ hybridization was seen in 39.0% cases. Forty-six patients had a median follow-up time of 32.5 months(range: 5-128 months) and the 5-year survival rate for stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ patients were 91.7% and 50.1%, respectively(

Objective:To build a medical service experience system based on role play of hospital staff, and explore its contribution to upgrading medical service, elevating medical service quality, and improving patients′ satisfaction.Methods:An indicator system for medical service experience was developed via literature review. 20 newly recruited hospital employees in 2019 were sampled randomly to form a service experience team, who were arranged to experience the full medical service process of outpatients and inpatients based on role play. The questionnaire for service quality based on patient perception and expectation was used to survey the expectation and perception values of those role players on their medical service experiences, and summarize the defects found on such six dimensions as hospital reliability, responsiveness, tangibility, assurance, empathy and cost-effectiveness. After due corrections of these defects, further experiences and patient satisfaction survey were made to assess the effects of such actions taken. Paired t test was used respectively in statistical analysis of service experience value and actual perception value, as well as the perception values before and after the actions taken, and χ2 test was used for a statistical analysis of patient satisfaction. Results:Role players experienced respectively at the emergency, outpatient and inpatient departments of the hospital for a week in August 2019. Statistics of their experiences indicated≥0.50 points difference between the mean expectation and perception values on doctor-patient communication, patient help responsiveness, outpatient process, examination report delivery duration, service attitude, patient trust on medical workers, medical environment and patient privacy protection.Following a 3-month reform, role players found improvements in such aspects as hospital reliability, responsiveness, tangibility, assurance, empathy and cost-effectiveness; patient satisfaction improved sizably in December 2019 over January of the same year( P<0.05). Conclusions:The construction and application of the medical service experience system based on role play of hospital staff prove highly useful in upgrading medical service actions, improving medical service quality, and improving patient satisfaction.
