Anaplastic lymphoma kinase-positive (ALK+) diffuse large B-cell lymphoma (DLBCL) is a rare subtype of DLBCL. ALK+DLBCL has a characteristic immunoblastic/plasmablastic morphology, a distinct immunophenotypic profile, and recurrent cytoge-netic/molecular genetic abnormalities. The occurrence of this type of lymphoma has been reported in both adult and pediatric popula-tions. Although rare, this new entity should be recognized because most cases follow an aggressive clinical course with a poor progno-sis. The response of ALK+DLBCL to conventional chemotherapy is poor. The recently discovered small molecule ALK inhibitor may provide a potential therapeutic option for patients with this disease.

Background and purpose:Nir1 is a transmembrane receptor for chemokine (C-C motif) ligand 18. CCL18 speciifcally binds to Nir1 at the cellular membrane of breast cancer cells to exert its invasion and metastasis. However, the speciifc mechanism of Nir1 is not clear in glioma. This study probed the effect and mechanism of Nir1 in the invasion of glioma cells.Methods:Western blot was used to detect the expression of Nir1 in glioma cells. siRNA plasmid was used to transfect U251 cells. Western blot was used to analyze the expression of Nir1 and protein phosphorylation of Akt in the cells transfected by Nir1 plasmid.In vitro Matrigel invasion assay was used to detect the invasive ability in the cells that were transfected. F-actin polymerization assay was used to detect F-actin recognition ability in cells.Results:The expression of Nir1 was higher in all glioma cells. After transfection, the invasion of siNir1/U251 was obviously decreased than the SCR/U251, F-actin content was reduced compared to the control group. Akt phosphorylation experiment result showed that the protein phosphorylation of Akt was enhanced in control group cells CCL18 following stimulation. However, the existence of CCL18 would affect the phosphorylation of Akt in siNir1/U251.Conclusion:Nir1 is high expression in glioma cells, and Nir1 binding to chemokine CCL18 promotes glioma cells invasion and metastasis through regulation the phosphorylation of Akt and F-actin polymerization .

Objective:The occurrence of numerous tumors, particularly classical Hodgkin's lymphoma (CHL), is related with Ep-stein-Barr virus (EBV) infection. However, the incidence of CHL and its association with EBV varies significantly with ethnicity, geo-graphic location, sex, and age. This study investigated the association of EBV infection with CHL in Northern Chinese Han population. Methods:EBV-encoded small RNA (EBER) was detected in 136 cases of CHL through in situ hybridization. Results:A total of 37 cas-es were EBER positive (28%). The mixed cellularity (MC) subtype had the highest positive EBER rate of 49%(23/47;P<0.001), fol-lowed by lymphocyte-rich subtype with 30%(3/10), nodular sclerosis (NS) subtype with 14%(10/73), and 1ymphocyte depletion with 0%(0/2). Our study identified a single age distribution in the third decade. Moreover, NS subtype showed an evident single peak in the third decade. However, MC subtype had a lower peak in the fifth decade. The incidence of EBER showed a bimodal age distribution with two peaks in the first and fifth decades (21.6%and 24.3%, respectively). Conclusion:CHL in Northern Chinese Han population was associated with EBV infection, particularly the MC subtype.

Objective To investigate the prognostic value of lymph node status evaluated by computed tomography (CT) in cervical carcinoma treated with radical chemoradiation therapy.Methods 209 patients with FIGO stage Ⅰ B-ⅣA uterine cervical carcinoma treated with radical chemo radiation therapy were enrolled.Lymph node status was evaluated based on site,number and size respectively by CT.Kaplan-Meier method was used to analyze the impact of lymph node status as well as other pathoclinical factors on overall survival (OS).Cox regression model was used to explore the relationship between independent prognostic factors and OS.Results Lymph node metastasis rates for stage Ⅰ B,Ⅱ,Ⅲ and ⅣA patients were 16.7 ％ (1/6),48.2 ％ (68/141),57.4 ％ (31/54) and 87.5 ％ (7/8),respectively.Variate analysis showed that FIGO stage,anemia before treatment,para-aortic lymph node metastasis,and the number (≥3) and size (maximum diameter ≥ 2.0 cm) of CT positive lymph node were significant unfavorable prognostic factors for OS (P ＜ 0.05).FIGO stage,the number of lymph nodes metastasis,pathologic diagnosis and treatment regimen were identified to be independent prognostic factors in multivariate analysis.Conclusion Under current therapeutic strategy of concomitant chemoradiotherapy,lymph node metastatic status evaluated by pretreatment CT is still a significant and independent prognostic factor for cervical cancer.

Objective:To systematically evaluate the clinical efficacy of oral ginger capsule or ginger powder in chemotherapy-induced nausea and vomiting in cancer patients.Methods:Computers searched Chinese Journal Full-text Database (CNKI), China Biomedical Literature Database (CBM), Wanfang Database, PubMed, EMbase, Web of Science, and Cochrane Library about oral chemotherapy in patients with cancer ginger correlation clinical curative effect of nausea and vomiting randomized controlled trial, supplemented by other search methods, the time range was built until July 2019. Quality evaluation and data extraction were performed independently by two investigators, and Meta analysis was performed by RevMan5.3 software.Results:A total of 12 articles and 13 studies were included, with a total of 1 105 patients. Meta-analysis showed that oral ginger capsule or ginger powder reduced the incidence of acute vomiting (risk ratio value was 0.76, 95% confidence interval was 0.59-0.98, P<0.05) and the severity of vomiting (mean difference value was-0.79, 95% confidence interval was-1.36--0.23, P<0.01), including the severity of acute vomiting (mean difference value was-1.39, 95% confidence interval was-2.72--0.06, P<0.05) and the severity of delayed vomiting (mean difference value was-0.46, 95% confidence interval was-0.82--0.10, P<0.05). However, there was no significant difference between the two groups in the incidence and severity of acute and delayed nausea ( P>0.05). Conclusions:This study demonstrates that oral ginger capsule or ginger powder is a complementary treatment for chemotherapy-induced nausea and vomiting in cancer patients, and more high-quality studies are needed to validate its clinical efficacy in the future.

Objective:To investigate the clinical and pathological features and immunophenotyping of keloidal cutaneous fibrous histiocytoma (FH) and dermatofibrosarcoma protuberans (DFSP) to provide evidence for clinical diagnosis and treatment.Methods:The clinical data were colleceted from March 2015 to March 2019 and retrospectively analyzed, including 12 cases of FH, 5 males and 7 females, aged 14-76 years, with average age (37.67±17.71) years and 9 cases of DFSP, 5 males and 4 females, aged 19-64 years, with average age (42.56±13.82) years. The clinical manifestations, histopathological features and immunophenotyping of FH and DFSP were compared.Results:The clinical manifestations of all cases were keloid-like lesions. All patients underwent surgical treatment. 12 cases of FH were diagnosed in the postoperation routine pathological examination and immunohistochemical staining, CD68 was positive in 10 cases, 9 cases of SMA were positive and all of S-100 were negative. 9 cases of DFSP were diagnosed and 2 cases were fibrosarcomatous DFSP among them. For the 7 cases of DFSP, CD34 were all positive, 5 cases of CD68 were negative, 6 cases of SMA were negative. For 2 cases of fibrosarcomatous DFSP, CD34, CD68 and SMA were all negative. During the follow-up period from 6 months to 4 years, there was no recurrence of FH cases, and 3 cases of DFSP recurred, 2 cases were fibrosarcomatous DFSP among them, and 1 case of fibrosarcomatous DFSP presented distant metastasis.Conclusions:The clinical manifestations and pathological features of some FH and DFSP are similar to keloids in a certain extent, and there is a little difficulty for clinical differential diagnosis. Early diagnosis and standardized treatment are crucial for prognosis.
