Application of PD-L1, PD-L2, CD30, CD23 and BCL-6 in Diagnosis and Prognostic Evaluation of Primary Mediastinal Large B-cell Lymphoma / 肿瘤防治研究

Objective To explore the application value of treatment-related markers PD-L1, PD-L2, CD30, CD23, BCL-2, BCL-6, MUM1 and GATA3 in the diagnosis and prognostic evaluation of primary mediastinal B-cell lymphoma(PMBL). Methods A retrospective study was conducted on 34 patients diagnosed with PMBL, and 31 patients with DLBCL-NOS which was not primary in the mediastinum were taken as control group. The expressions of 8 proteins were detected by IHC staining. Results The median percentages of tumor cells with PD-L1, PD-L2 and CD30 expression in PMBL group were 70% (30%, 90%), 25% (0, 70%) and 17.5% (0, 60%) respectively, which were significantly higher than those in the DLBCL-NOS group (P < 0.05). The positive rates of CD30 and CD23 in PMBL group were 61.76% (21/34) and 76.47% (26/34) respectively, significantly different with those in the DLBCL-NOS group (P=0.000). The survival curve of PMBL patients with CD30 or BCL-6 expression showed a trend of poor prognosis, despite the P value was > 0.05. Conclusion The high expression levels of PD-L1, PD-L2 and CD30 in PMBL are helpful to accurately identify more patients who may respond to immune or targeted therapy. Immunohistochemical staining of PD-L1, PD-L2, CD30 and CD23 is helpful for the differential diagnosis of PMBL and DLBCL-NOS. As candidate prognostic indicators of PMBL, CD30 and BCL-6 should be further studied in a larger number of samples.

Immune Correlates of Resistance to Trichinella spiralis Reinfection in Mice

The immune correlate of host resistance induced by reinfection of Trichinella spiralis remains unclear. In this study, we investigated immune correlates between the resistance and serum IgG antibody level, CD23⁺ IgM⁺ B cells, and eosinophil responses induced by T. spiralis reinfection. Mice were primarily infected with 10 or 100 T. spiralis larvae (10 TS, 100 TS), respectively, and after 4 weeks, they were challenge infected with 100 T. spiralis larvae (10–100 TS, 100-100 TS). Upon challenge infections, 10–100 TS mice induced significantly higher levels of T. spiralis-specific total IgG antibody responses in sera and antibody secreting cell responses in spleens compared to 100-100 TS mice, resulting in significantly reduced worm burdens in 10–100 TS mice (60% and 70% reductions for adult and larvae, respectively). Higher levels of eosinophils were found in mice primarily infected with 10 TS compared to those of 100 TS at week 8 upon challenge. CD23+ IgM+ B cells were found to be increased significantly in mice primarily infected with 10 TS. These results indicate that primary infection of 10 larvae of T. spiralis, rather than 100 larvae, induces significant resistance against reinfection which closely correlated with T. spiralis-specific IgG, eosinophil, and CD23+ IgM+ B cell responses.

The Clinical Significance of Serum CD23 and CD25 in Chronic Cough Patients / 결핵

BACKGROUND: Cough Coughing is the most common complaint for which patients seek medical service. When cough sustains caughing continues over 3 weeks in non-smokers who do not take cough-provoking drugs, they are classified as patients with chronic cough. As well-known, three Three well known main causes of chronic caugh are diseases - (delete) postnasal drip syndrome, bronchial asthma and gastroesophaseal reflux disease. - comprise the majority of the causes of chronic cough. Among them, postnasal drip syndrome is reported to be the most common cause of all in chronic cough diseases, and allergic inflammation plays an important role in the pathogenesis of postnasal drip syndrome. CD23 and CD25 which are low affinity receptor for IgE and IL-2 receptor alpha, respectively, are closely related to allergic inflammation and we evaluated the role of them in their roles were evaluated in chronic cough patients. METHODS: We evaluated 105 patients with chronic cough and selected 56 patients for measurement of serum CD23 & CD25 level levels. We selected 10 normal, medical students for comparison of serum CD23 & CD25 level. levels. RESULT: We found that postnasal drip syndrome was The postnasal drip syndrome was found to be the most common cause of chronic cough. Serum CD23 and CD25 level were did not increased increase in chronic cough patient compared to normal controls. However in bronchial asthma patient, serum CD23 level was increased relative to normal control (p<0.05). CONCLUSION: In bronchial asthma presented as chronic cough, lymphocyte mediated allergic inflammation might be may related with the pathogenesis of the disease.
