Clinicopathological analysis and literature review of Burkitt-like lymphoma with 11q aberration / 中国综合临床

Objective:To investigate the clinicopathological features,differential diagnosis,treatment and prognosis of Burkitt-like lymphoma with 11q aberration (BLL-11q).Methods:The clinical manifestations,histological morphology,immunophenotype and molecular genetic changes of 2 cases of BLL-11q admitted to the department of pathology of The First People's Hospital of Lianyungang in 2020 and 2021 were analyzed retrospectively,and the relevant literatures were reviewed.Results:Patients were found with right neck masses inadvertently and grew rapidly. They presented with localized disease with Ann Arbor stages IA and IIA. Microscopically, the normal structure of the lymph node disappeared and was replaced by a diffuse proliferation of lymphocytes, with consistent morphology and medium size. And the presence of "star-sky" phenomenon was obvious, the morphological characteristics were similar to Burkitt lymphoma. Immunophenotypically, tumor cells were diffusely positive for CD20, CD79α, PAX5, CD10 and Bcl-6, partly moderately positive for C-MYC and MUM-1, however, CD3, Bcl-2, CD30 and TDT were negative,Ki-67 positive index was more than 95%, and EBER was negative. FISH detection showed that MYC, Bcl-2, and Bcl-6 were negative. Both cases had the 11q23.3 gain and 11q24.3 loss. Both patients were treated with chemotherapy and followed up for 10-22 months,and achieved complete remission and disease-free survival.Conclusion:BLL-11q is a rare germinal center B-cell lymphoma with abnormal long arm of chromosome 11 and lack of MYC gene rearrangement. It should be distinguished from Burkitt lymphoma, diffuse large B-cell lymphoma, B-lymphoblastic lymphoma, large B-cell lymphoma with IRF4 rearrangement and high-grade B-cell lymphoma. On the basis of morphology and immunophenotype, the diagnosis depends on genetic detection. There may be a better prognosis.

The changes and clinical significance of plasma lipoprotein-associated phospholipase A2,C-reactive protein and cardiac troponin Ⅰ in patients with acute coronary syndrome / 中国基层医药

Objective To investigate the relationship between lipoprotein associated phospholipase A2 (Lp－PLA2)and atherosclerotic plaque instability in patients with acute coronary syndrome (ACS),and to provide theoretical basis for diagnosis and treatment of ACS.Methods From September 2015 to February 2016,80 patients with ACS in Shidao People's Hospital of Rongcheng were selected as the study group,including 38 cases in unstable angina group(UAP group),24 cases in non ST segment elevation myocardial infarction group (NSTEMI group), 18 cases in ST segment elevation myocardial infarction group(STEMI group).Forty patients with stable angina pectoris (SAP group)and 40 healthy subjects(healthy group)were selected as control group.Each group was collected 8 hours fasting morning blood sample,the levels of Lp－PLA2,C reactive protein(CRP),troponin Ⅰ,and low density lipoprotein were detected,in order to compare the differences among the groups and the correlation between Lp－PLA2 and ACS plaque instability was analyzed.Results The levels of Lp－PLA2,CRP,troponin Ⅰ and low density lipopro-tein in the ACS group were (312.63 ±11.14)ng/mL,(21.98 ±7.83)mg/L,(0.720 ±0.490)μg/L,(174.76 ± 30.82)mg/dL,respectively,which were significantly higher than those of the healthy group [(141.14 ±12.30)ng/mL, (2.38 ±1.68 )mg/L,(0.010 ±0.003 )μg/L,(79.24 ±17.80 )mg/Ml],and stable angina pectoris group [(176.42 ±12.44)ng/mL,(4.22 ±3.68)mg/L,(0.010 ±0.004)μg/L,(96.54 ±19.41)mg/mL].There were statistically significant differences among all groups(F＝3.07,1.99,2.43,3.25,all P＜0.01).The levels of CRP, Lp－PLA2 and cTnI in ACS patients with different types of the STEMI group,NSTEMI group,UAP group had statisti-cally significant differences,which of the STEMI group were higher than those of the NSTEMI group,which of the NSTEMI group were higher than those of the UAP group(F＝5.15,3.47,2.43,all P＜0.05).Correlation analysis showed that the level of Lp－PLA2 was positively correlated with low density lipoprotein(r＝0.625,P＜0.01)and lipoprotein a(r＝0.532,P＜0.01).logistic regression analysis showed that Lp －PLA2 and CRP were significant independent risk factors of ACS,Lp－PLA2(OR＝1.613,95%CI:1.292 －1.992,P＜0.01),CRP(OR＝1.452, 95%CI:1.210-1.782,P＜0.01).Conclusion Lp－PLA2 is independent risk factor of ACS.Lp－PLA2 is involved in the inflammatory reaction of ACS,and is strongly associated with the stability of atherosclerotic plaque.

Diagnostic utility of immunohistochemical markers SALL4, D2-40 and Glypican-3 in primary testicular germ cell tumors / 临床与实验病理学杂志

Purpose To investigate the diagnostic utility of the immunohistochemical markers SALL4, D2-40 and Glypican-3 in prima-ry testicular germ cell tumors (TGCTs). Methods The expression of SALL4, D2-40 and Glypican-3 protein was detected by EnVi-sion immunohistochemical method in 56 cases of primary testicular germ cell tumors, including 5 intratubular germ cell neoplasms ( IT-GCNs) , 10 seminomas, 14 embryonal carcinomas ( ECs) , 14 yolk sac tumors ( YSTs) , 1 choriocarcinoma, 5 immature teratomas and 12 mature teratomas. 10 normal testicular tissues and 5 lymphomas were selected as control. Results All of ITGCNs, seminomas, YSTs and ECs were diffusely strongly positive for SALL4. Focal SALL4 staining was seen in choriocarcinoma, 3 of 5 immature terato-mas and 3 of 12 mature teratomas. All of ITGCNs, seminomas showed diffusely strong D2-40 staining. ECs (4/14) were focally posi-tive for D2-40, while choriocarcinoma, YSTs and teratomas were negative for D2-40. Glypican-3 was diffusely positive in YSTs (13/14), and focally weakly positive in ECs (2/14), respectively. ITGCNs, seminomas, choriocarcinoma and teratoma were negative for Glypican-3. In contrast, 10 normal testicular tissues and 5 lymphomas showed no SALL4, D2-40 and Glypican-3 staining. Conclu-sions SALL4 is a useful diagnostic marker with high sensitivity and specificity for TGCTs. Combination of SALL4, D2-40 and Glypi-can-3 is helpful to the diagnosis and differential diagnosis for TGCTs.

Expression and Clinical Significance of Twist Protein in Non-small Cell Lung Carcinoma / 中国医科大学学报

Objective To study the clinical significance and the expression of Twist protein in non-small cell lung cancer(NSCLC).Methods The expression of Twist protein was examined in formalin-fixed paraffin-embedded tissue samples of 61 NSCLC by S-P immunohistochemical method.Results The expression level of Twist in NSCLC was significantly higher than that of normal lung tissue;the positive expression of Twist protein was related to the histotype,clinical stage and lymph node metastasis;the expression level of Twist protein in the cases whose survival time was less than 4 years was significantly higher than that in the cases whose survival time more than 4 years;the Cox analysis revealed that smoking and lymph node metastasis were the noticeable affective factors on the death of the NSCLC patients after surgery.Conclusion s Twist gene played an important role in the genesis and development of NSCLC,and was related to the prognosis.

Relationship between expression of Twist and KiSS-1 and progonosis in non-small cell lung cancer / 中国癌症杂志

Background and purpose:Twist has been identifi ed as tumor metastasis promoter transcription factor and KiSS-1 has been identified as tumor metastasis suppressor gene,and both of them have been identified to be associated with the metastatic potential of non-small cell lung cancer(NSCLC) .Our aim was to identify the expression of both Twist and KiSS-1 in NSCLC and analyze their correlation with patients’ survival.Methods:Immunohistochemical staining using monoclonal Twist and KiSS-1 antibody were performed on paraffi n embedded specimens from 61 patients diagnosed with NSCLC,and 15 specimens of tumor surrounding lung tissue were used as control.The association with clinicopathologic data and prognosis of NSCLC were analyzed.Results:The expression of Twist was significantly higher in NSCLC than in tumor surrounding lung tissue(P
