Diffuse large B-cell lymphoma (DLBCL) represents the most common type of malignant lymphoma. DLBCL is heterogeneous with respect to morphology, immunophenotype, biology, clinical presentation and outcome. Constitutive activity of the NF-κB pathway may contribute to the poor prognosis of patients with activated B cell-like (ABC) subgroup of DLBCL, caspase recruitment domain 11 (CARD11) is the important signal protein in the signaling pathway of NF-κB. Furthermore, various pre-clinical data have proved the importance of CARD11 in DLBCL. This review summarizes the biological characteristics of CARD11, and its relationship with NF-κB signaling transduction pathway and the outcome of DLBCL, so that we can better understanding the pathogenesis and new therapeutic target of DLBCL.

Objective To explore the diagnostic value of cerebrospinal fluid(CSF) biochemical indexes in central nervous system (CNS) infection .Methods The results of CSF culturing and detection of biochemical indexes including glucose(Glu) ,lactate dehy‐drogenase(LDH) ,chloride ion(Cl) and protein(PRO) were collected from the First Affiliated Hospital of Xi′an Jiaotong University from September to December 2013 .Taking the results of CSF culturing as golden standard ,the biochemical indexes were analyzed by using receiver‐operating characteristic(ROC) curve for single index and combined indexes .Results A total of 157 CSF speci‐mens were collected ,including 39 culture‐positive specimens and 118 culture‐negative specimens .Areas under ROC curve(AUC) of Glu ,LDH ,Cl and PRO were 0 .653 ,0 .633 ,0 .626 ,0 .671 ,respectively .The AUCs of combined detection of these biochemical inde‐xes were higher than those of single index ,and the AUC of combined detection of these four indexes was the largest ,up to 0 .694 , but all were less than 0 .7 .Conclusion Glu ,LDH ,Cl and PRO all could be independent biochemical indexes for diagnosing CNS in‐fection ,among which PRO has the highest diagnostic value .And combined detections of these indexes are better than single detec‐tions ,especially combination of four indexes ,which is the strongest indicator ,but accuracy is low whether single or combined detec‐tion .More sensitive and specific biomarkers of CSF should be explored for rapid diagnosis of CNS infection .

Objective To study and evaluate the inhibitory role of ?-carboxyglutamic acid(Gla)in the Gla domain of prothrombin in the formation of calcium oxalate crystals. Methods The addition of morpholine and formaldehyde to the solution of prothrombin caused the conversion of 8 Gla to ?-methyleneglutamic acid (8?-MGlu)or 2 Gla to ?-methyleneglutamic acid(2?-MGlu) ,the inhibitory activity of which to calcium oxalate crystallization was detected with seeded crystallization technique. Results The conversion of Gla to ?-MGlu leads to the decreased inhibitory activity of prothrombin to calcium oxalate crystallization,the inhibitory index being decreased from normal 14.2 to 12.8 of 2?-MGlu or 5.0 of 8 ?-MGlu prothrombin respectively. Conclusions Gla in prothrombin may play an important role to inhibit the formation of calcium oxalate calculi.
