ABSTRACT

Objective@#To investigate the pathological features and clinical manifestation of pediatric nodal marginal zone lymphoma(NMZL).@*Methods@#Histological morphology and immunophenotype of 7 cases of pediatric NMZL were retrospectively reviewed at Beijing Friendship Hospital Affiliated to Medical University between January 2008 to October 2018. Clonal rearrangement analysis was performed. Clinical information including patient follow-up data were analyzed.@*Results@#All 7 patients were male with a median age of 15 years aged from 10 to 26 years. All patients presented with only lymph node enlargement without B symptoms, including cervical lymph node (5 cases), preauricular lymph node (1 case) and retroauricular lymph node (1 case). Histologically, all cases showed irregular large follicles on the edges with widened marginal areas and intervesicular areas, and lesional cells were uniform with progressive transformation of germinal center centers along with a small amount of intrinsic lymphoid tissue. All 7 cases showed diffuse CD20 positivity both follicle and interfollicular region along with 30%-40% positivity in the interfollicular region (pathological region). Markers of other B-cell lymphomas werenot expressed. All 7 cases were positive for immunoglobulin(Ig) gene rearrangement. None of the patients showed no recurrence up on after follow-up for an average of 13 months.@*Conclusions@#Pediatric NMZL is a rare type of lymphoma that has a unique morphology and occurs almost exclusively in male children and young adults and often in head and neck lymph nodes. It has an excellent prognosis. Therefore, awareness of the disease with accurate diagnosis is important.

ABSTRACT

Objective: To investigate the effect of self-etching adhesive with different unsealing time on the microleakage of the adhesive interface between tooth and resin. Methods: Unopened self-etching adhesives, Scotchbond Universal (S) and Xeno V+ (X) were respectively used to adhere Z350 resin for restoration of the prepared occlusal cavities sized 4 mm × 4 mm × 4 mm (n = 40) . The methylene blue staining method was used to observe the microleakage of the adhesive interface between the tooth and filling material at the instant moment, 1, 2 and 3 months after the self-etching adhesives was opened (n = 10) . Results: (1) Increase of microleakage in S group was found with the time span after unsealing, and there was a statistical difference between the instant moment and 3 months after unsealing (P<0. 05) . (2) There was no significant difference at the 4 test time points in X group (P>0. 05), although the microleakage value of the samples were increased with the increase of the time after unsealing. (3) The microleakage of X group was greater than that of S group at the instant moment and 1 month after unsealing (P<0. 05) . Conclusion: Unsealing time may increase the microleakage of the adhesive interface between the tooth and the filling material, the effect varies with the types of the adhesives.

ABSTRACT

Objective@#To investigate clinicopathologic features and prognostic factors of mantle cell lymphoma(MCL).@*Methods@#The clinical data of 349 MCL patients diagnosed at Beijing Friendship Hospital from January 2004 to January 2016 were retrospectively collected. Corresponding histological sections were reviewed. Additional studies included immunohistochemical staining using the MaxVision two-step method, IgH/CCND1 fusion gene detection by fluorescent in situ hybridization (FISH), and correlative statistical analysis.@*Results@#Of 349 patients with MCL, the median patient age was 61 years (range: 25-83 years, M∶F=2.7∶1.0) and the age of 243 patients ranged from 51 to 70 years (69.6%). Those with B symptoms accounted for 22.4% (70/313). Most of the patients presented with superficial lymphadenopathy and the clinical stage Ⅲ-Ⅳ accounted for 76.1% (235/309). Extranodal involvement was seen in 47.9% (148/309), among which the gastrointestinal tract accounted for 31.8% (47/148) and splenic involvement accounted for 15.4% (47/305). Three hundred and nine (88.5%) cases were of classical type and 40 (11.5%) cases were of aggressive variant type, and all were composed of proliferating lymphoid cells. All the tumors were positive for CD20 and cyclin D1, and 98.6% (344/349) tumors were weakly positive or positive for CD5. FISH test was positive in 12 cases that were CD5 negative and with cyclin D1 partial expression.Two hundred and forty-three (69.6%) patients had a median follow-up of 26 months (range: 3-108 months). The 3- and 5-year overall survival rates for patients were 63.0% and 34.8%, respectively. Single factor analysis showed that age of >60 years, splenic involvement, aggressive variant type, incompletely overlapping type [Based on the degree of overlap ≥90% and <90% between the follicular dendritic cell (FDC) meshwork and tumor cells, the tumors were divided into the completely overlapped type and incompletely overlapped type] and Ki-67 index >40% had poor prognosis (P<0.05). Multiple factor Cox proportional risk regression analysis after removing the aggressive variant type showed that age, splenic involvement, the degree of overlap between the FDC meshwork and tumor cells and Ki-67 index were independent prognostic factors for overall survival rate of MCL patients (P<0.05).@*Conclusions@#MCL is more commonly found among middle-aged and elderly men. Patient age, splenic involvement, degree of overlap between FDC meshwork and tumor cells and Ki-67 index are the independent prognostic indicators for MCL.

ABSTRACT

Objective@#To investigate the clinicopathological features of EBV-positive T/NK cell lymphoproliferative diseases (EBV+ T/NK-LPD).@*Methods@#The clinical characteristics of 156 cases of EBV+ T/NK-LPD were collected from August 2002 to March 2015 at Beijing Friendship Hospital, Capital Medical University. Immunohistochemical staining, EBER in situ hybridization and clonal analysis of TCR gene were performed. All patients were followed up.@*Results@#There were 106 male and 50 female patients; patients′ age ranged from 1 to 75 years (median 20 years). The course of the diseases before diagnosis ranged from 2 to 540 months (median 20 months). Fever was noted in 122 patients (78.2%), 108 patients had lymphadenopathy (69.2%), and 75 patients had hepatosplenomegaly (48.1%). Thirty-three cases were grade 1, 68 cases were grade 2, and 55 cases were grade 3. TCR gene arrangement analysis was performed in 45 cases, and 33 cases (73.3%) showed clonal rearrangement. The follow-up period ranged from 1-134 months, and 44 patients (28.2%) died. There was a trend of increased death rate associated with increasing grade (P>0.05).@*Conclusions@#There are many types of EBV+ T/NK-LPD, and they can be classified as systemic, relatively localized and localized. The prognosis should be based on a comprehensive analysis of pathology and clinical data. There is no significant correlation between morphological grade and mortality. An important goal of therapy is to prevent serious complications.

ABSTRACT

Objective@#To investigate the clinicopathologic features and prognosis of gastrointestinal mantle cell lymphoma (GI-MCL).@*Methods@#Clinical data of 38 GI-MCL patients diagnosed at Beijing Friendship Hospital from January 2002 to January 2016 were retrospectively reviewed morphologically and immunophenotypically. IgH/CCND1 gene fusion was assessed by fluorescent in situ hybridization (FISH). For comparison, 60 cases of non-GI-MCL were randomly selected to extract the differences inclinicopathological features and patient survival between the two groups.@*Results@#Of 38 patients with GI-MCL, the median age was 62 years (range: 35-78 years, 23 males and 15 females), of which patients of 60 years of age or older accounted for 55.3%. Patients with clinical course of less than 6 months accounted for 81.1%(30/37). The main symptoms included abdominal pain, diarrhea, anorexia and hematochezia. Those with B symptoms accounted for 32.4%(12/37). The tumor most often involved lleocecal region (57.9%, 22/38), followed by rectum (36.8%, 14/38) and sigmoid colon (28.9%, 11/37), and the stomach accounted for 18.4%(14/38). Endoscopic polypoid lesions were found in 33 cases (86.8%, 33/38), of which 22 cases (66.7%, 22/33) were multiple. Five cases (13.2%, 5/38) presented with local protuberant neoplasm. According to Ann Arbor staging, 3 cases (7.9%, 3/38) were at stage Ⅰ, 4 cases (10.5%, 4/38) were at stage Ⅱ, and 31 cases (81.6%, 31/38) were at stage Ⅳ. The number of patients with tumor involvement of abdominal and retroperitoneal lymph nodes accounted for 45.7%(16/35), including 41.7%(15/36) involving the superficial lymph node, 17.1%(6/35) involving extranodal sites, and 23.5%(8/34) having splenomegaly. All of the 38 cases were classic MCL, and the tumor was composed of uniform lymphoid cells and effacing normal mucosal structure. All tumors were positive for CD20 and CD5. 97.4% (37/38) tumors were positive for cyclin D1, and 92.0% (23/25) tumors were positive for SOX11. FISH test was positive in 1 case of cyclin D1 negative tumor. Twenty-eight patients (73.7%) had a median follow-up of 25.0 months (range: 3-79 months). The 3-year survival rate for stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ of patients were 80.0% and 69.1%, respectively (P> 0.05). The 3-year survival rate for GI-MCL and non-GI-MCL patients were 71.7% and 72.5%, respectively (P>0.05). Single factor analysis showed that age of >60 years and splenomegaly were correlated with a worse overall survival rate (P<0.05).@*Conclusions@#Gastrointestinal malaise is the most common presenting symptom in GI-MCL patients. GI-MCL more commonly involves colorectum with more frequent multiple polypoid lesions. Patients of age >60 years and with splenomegaly have poor prognosis. There is no difference in the prognosis between GI-MCL and non-GI-MCL patients.

ABSTRACT

Objective@#To determine the cut-off values of Ki-67 labeling index (LI) in the histological grading of follicular lymphoma (FL).@*Methods@#Clinicopathological data of 350 FL patients diagnosed at Beijing Friendship Hospital from June 2014 to January 2016 were analyzed retrospectively by quantitative evaluation and statistical analysis of Ki-67 LI.@*Results@#Of the 350 patients with FL, the male and female ratio was 1.1 and the average age was (50.2±14.0) years with a median age of 51 years (range 4 to 82 years). The tumors were graded as grade Ⅰ-Ⅱ in 215 cases (61.4%), grade Ⅲ A in 105 cases (30.0%), and grade Ⅲ B in 30 cases (8.6%). The average Ki-67 values were (22.8%±8.3%) for the FL low (grade Ⅰ-Ⅱ) and (50.4%±10.7%) for high grade (Ⅲ A and Ⅲ B) and were statistically significant by Mann Whitney U test (P<0.01). Receiver operated characteristic curve analysis showed that the best diagnostic cut-off value of low grade FL was 35% (sensitivity of 96.3% and specificity of 93.3%) with the largest area under curve (AUC=0.990, P<0.01, 95%CI for 0.982-0.998). According to the analysis of four lattice diagnostic tests, Ki-67 LI >40% was an important factor (χ2=230.733, P<0.01) in predicting high grade FL. When the cut-off value of Ki-67 LI was set at 40%, high grade LF could be diagnosed with the greatest sensitivity (98.1%) and specificity (87.7%). Moreover, a significant correlation between the Ki-67 LI and the pathological grade of FL (r=0.836, P<0.01) was observed.@*Conclusions@#Ki-67 LI of below a cut-off value of 35% is a reliable indicator of low grade FL.Ki-67 over 40% is consistent with high grade FL. These Ki-67 cut-off values may serveas an important auxiliary indicator in the grading of FL.

ABSTRACT

Objective@#To analyze clinical, pathological, molecular and genetic characteristics of Burkitt-like lymphoma with chromosome 11q aberration.@*Methods@#A case of Burkitt-like lymphoma with 11q aberration was presented at Beijing Friendship Hospital in November 2016 with detailed clinicopathological features, immunophenotypes, Epstein-Barr virus(EBV) status and molecular genetic characteristics.@*Results@#The patient was a 38-year-old man presenting with the cervical lymphadenopathy. In morphology, the tumor had the similar characteristics of Burkitt lymphoma, including diffuse infiltration of medium to large lymphoid cells, and presence of"starry sky"phenomenon. Immunophenotypically, the tumor cells were positive for CD20, CD10, bcl-6, but negative for bcl-2. MUM-1 showed weak and patchy positivity. Ki-67 index was more than 95%. C-MYC expression was seen in about 50% of tumor cells. EBV in situ hybridization was negative. IgH and IgK genes were clonally rearranged.Fluorescence in situ hybrization detection using MYC break probe was negative but ATM gene amplification on chromosome 11q was detected. The patient did not receive any chemotherapy or radiotherapy and had not recurrence during the 10 months follow-up.@*Conclusion@#Burkitt-like lymphoma with chromosome 11q aberration has similar clinical, morphological and immunological characteristics to classic Burkitt′s lymphoma.

ABSTRACT

Objective@#To investigate clinicopathological features and prognosis of tonsillar mantle cell lymphoma(TMCL).@*Methods@#Clinical data of 25 patients with TMCL at Beijing Friendship Hospital, Capital Medical University from 2002 to 2016 were included. All the cases were reviewed microscopically. Various immunohistochemical stains were performed using the MaxVision two-step method. IgH/CCND1 gene fusion was detected by fluorescent in situ hybridization(FISH). Additionally, randomly selected 40 cases of non-tonsil MCL of the same period were compared.@*Results@#Among all mantle cell lymphomas (MCL), TMCL accounted for 5.6%(25/449). The median age of the patients was 60 years(range: 44-82 years) with a M∶F ratio of 5.3 to 1.0. The main symptoms were sore throat and foreign body sensation and patients usually presented with enlargement or mass of tonsil. At the early stage of the disease, 18 cases(72.0%) were clinically misdiagnosed as tonsillitis. Lymph node involvement was present in 76.0%(19/25) of the patients. There were 4 cases(16.0%)with current splenic involvement, 11 cases(44.0%) with pharyngeal focal recidivism, and 3 cases(12.0%) with involvement of other non-lymphoid organs. Morphologically, tonsillar architectures were effaced at various degrees. Eighteen MCL cases showed classical type and 7 cases were blastoid variant. All tumors were positive for CD20 and cyclin D1. 92.0%(23/25) tumors showed weakly positive or positive expression for CD5. FISH test that IgH/CCND1 gene fusion was positive in two CD5 negative classical cases. 18 patients(72.0%) had a median follow-up time of 26 months(range: 6-81 months). The difference of survival rate between stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ patients was not statistically significant(P>0.05). Compared with NTMCL, TMCL was found to have higher proportion of stage Ⅰ-Ⅱ disease (χ2=12.789, P<0.01), lower the proportion of non-lymphatic organ involvement (χ2=8.125, P<0.01), and better prognosis (χ2=4.351, P=0.037).@*Conclusion@#The incidence of TMCL is low and prone to be misdiagnosed as tonsillitis. Patients with TMCL are more likely at stage Ⅰ-Ⅱ at presentation and the prognosis is better than that of NTMCL.

ABSTRACT

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(P<0.05). The 5-year survival rate for MCCHL-R was lower than typical MCCHL patients. Single factor analysis showed that age of >45 years, extranodal involvement and stage Ⅲ-Ⅳ were correlated with poorer 5-year survival rate(P<0.05). Multiple factors Cox proportional hazards regression showed that extranodal involvement was the independent prognostic factor(RR: 4.352, 95%CI: 1.122-16.879, P<0.05).@*Conclusions@#MCCHL-R is more common in young people. The tumor has pathological features of classic Hodgkin lymphoma enriched with the tumor cells(>10%) and similar immunophenotype to classical Hodgkin lymphoma. Compared with typical MCCHL, extranodal disease is an independent prognostic factor of MCCHL-R.

ABSTRACT

Objective To explore the effect of different hemostatic methods on ovarian function in la-paroscopic ovarian endometriosis cyst enucleation. Methods 200 cases of stage I and II ovarian endometriosis cyst admitted to our hospital from Jan. 2012 to Apr. 2014 were selected. All patients underwent conventional la-paroscopic ovarian endometrial endometriosis cyst enucleation. According to intraoperative hemostasis methods, patients were divided into 3 groups: suture group (n=70), electric coagulation group (n=70), and ultrasonic scalpel group (n=60). Follicle-stimulating hormone (FSH) and antibody forming cells (AFC) on admission and at 1, 3, 6, and 12 months after surgery were recorded. Peak systolic blood flow of ovarian stromal artery (PSV) was also observed. Results FSH for all the three groups were improved compared with that on admission, and the difference had statistical significance (P0.05). however, AFC of the suture group at 3, 6, and 12 months after surgery was significantly im-proved compared with those of the the electric coagulation group and ultrasound knife group. The difference had statistical significance (P<0.05). Vaginal type B ultrasonic examination after operation showed that PSV of the su-ture group was higher than that of the electric coagulation group and ultrasound knife group at the second menstru-ation and at the 6-month menstruation after surgery. The difference of PSV between the 3 groups had statistical significance (P<0.05). Conclusion Compared electric coagulation hemostasis and ultrasonic scalpel hemostasis, the suture method can reduce damage of ovarian function in patients with ovarian endometriosis cyst, which is worth to promote.

ABSTRACT

<p><b>OBJECTIVE</b>To study the clinicopathologic features and pathologic diagnosis and differential diagnosis of angioimmunoblastic T-cell lymphoma with HRS-like cells.</p><p><b>METHODS</b>Six 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.</p><p><b>RESULTS</b>The 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.</p><p><b>CONCLUSIONS</b>The 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.</p>

ABSTRACT

Objective To investigate CT and MRI imaging of Warthin tumor of parotid gland.Methods CT and MRI character-istics of 5 1 patients confirmed as Warthin tumor by operation and pathology were analyzed retrospectively.Results Among 5 1 cases, 43 patients were males,and 8 patients were females.A total of 84 lesions were found in all cases,20 cases had at least 2 lesions.The margins of lesions were well-defined.68 lesions were round or elliptical.45 lesions located in the posterior and inferior quadrant of the parotid gland completely or premodinantly.The density and signal of most lesions were homogeneous.The parenchymal area of most lesions showed an early moderate-remarkable enhancement.Small blood vessels surrounded the lesions in 1 9 cases.Conclusion CT and MRI are important and valuable for the diagnosis of Warthin tumor.

ABSTRACT

Medical insects are an important part of traditional Chinese medicine, their biomedical research and development of insects are gaining attention. The research and application of insect sex pheromone in this area also draws great attention. Currently, in-sect sex pheromone is mainly used for pest control in agroforestry. The review briefly describes the chemical constituents, release, and application of insect sex pheromones;meanwhile, the application of insect sex pheromone and its uses in mass trapping, mating disrup-tion, and pest control, in the insect resources development are preliminarily discussed.
