OBJECTIVE@#To investigate the clinical characteristics, diagnosis, and treatment of one patient with primary adrenal natural killer/T-cell lymphoma (PANKTCL), and to strengthen the understanding of this rare type of lymphoma.@*METHODS@#The clinical manifestations, diagnosis and treatment process, and prognosis of the patient admitted in our hospital were retrospectively analyzed.@*RESULTS@#Combined with pathology, imaging, bone marrow examination, etc, the patient was diagnosed with PANKTCL (CA stage, stage II; PINK-E score 3, high-risk group). Six cycles of "P-GemOx+VP-16" regimen(gemcitabine 1 g/m2 d1 + oxaliplatin 100 mg/m2 d 1 + etoposide 60 mg/m2 d 2-4 + polyethylene glycol conjugated asparaginase 3 750 IU d 5) was performed, and complete response was assessed in 4 cycles. Maintenance therapy with sintilimab was administered after the completion of chemotherapy. Eight months after the complete response, the patient experienced disease recurrence and underwent a total of four courses of chemotherapy, during which hemophagocytic syndrome occurred. The patient died of disease progression 1 month later.@*CONCLUSION@#PANKTCL is rare, relapses easily, and has a worse prognosis. The choice of the "P-GemOx+VP-16" regimen combined with sintilimab help to improve the survival prognosis of patient with non-upper aerodigestive tract natural killer /T-cell lymphoma.

OBJECTIVE@#To investigate the prognostic evaluation value of neutrophil-lymphocyte ratio (NLR) in patients with newly diagnosed angioimmunoblastic T cell lymphoma (AITL).@*METHODS@#Clinical data of 39 patients with newly diagnosed AITL in our hospital from March 2010 to August 2018 were colleated and retrospective analyzied, and the relationship between NLR before treatment and the prognosis of AITL patients was analyzed.@*RESULTS@#Among 39 AITL patients, the median value of NCR was 5.43. Based on the cut-off value (5.43), all the patients were divided into 2 groups: high NLR group (5.43, n=20) and a low NLR group (<5.43, n=19). The total effective rate of treatment was lower in the high NLR group as compered with low NLR group (P=0.041). Univariate analysis showed that, age >60 years old, extranodal involvement>1 as well as high NLR were the independent risk factors that affected overall survival (OS) in newly diagnosed AITL patients. Multivariate Cox analysis showed that extranodal involvement>1 and high NLR were the independent risk factors that affected OS in newly diagnosed AITL patients.@*CONCLUSION@#The NLR may be an independent prognostic factor in patients with newly diagnosed AITL. High NLR associated with poor prognosis.

<p><b>OBJECTIVE</b>To explore clinical characteristics of the Primary Adrenal Lymphoma(PAL), so as to enhance the understanding of diagnosis, treatment and prognosis of PAL.</p><p><b>METHODS</b>The clinical data of 2 patients with PAL retrospectively analyzed and the clinical characteristics were explored in combination with releted literalures.</p><p><b>RESULTS</b>Adrenal gland neoplasm was found in 2 patients by imaging examination. The pathological type of one case was diffuse large B cell lymphoma, the other one was extranodal NK/T-cell lymphoma. The former refused to hosipitali3t and the other received to be admited in hospital after the definite diagnosis. She died at the 32th day after diagnosis, due to the complication with acute pancreatitis before chemotherapy. The latter accepted the scheme of"Gemox"combining with the scheme"VP-16+DXM"to control hemophagocytic lymphohistiocytosis. The patient's condition deteriorated rapidly after a short period of improvement, then died at the 40th day after chemotherapy because of multiple organ failure.</p><p><b>CONCLUSION</b>PAL is a rare extra-nodal lymphoma with higher malignancy, the combination of chemotherapy and radiotherapy results in the best outcome among all the treatments. The prognosis of patients with different pathological types was diverse, thus it is very important to choose the appropriate treatment according to different pathological types.</p>

OBJECTIVE@#This work aimed to evaluate the influence of smear layer on the bonding effectiveness and durability of the self-adhesive resin cements to dentin.@*METHODS@#A total of 48 fresh caries-free third molars with exposed dentin surface were divided into two groups. The dentin surfaces were treated using a standard grit diamond bur (group A) or further polished using a fine grit diamond bur (group B) and then bonded with either of the two self-adhesive resin cements, namely, Clearfil SA Cement (CSA, Kuraray) and Multilink Speed (MS, Ivoclar Vivadent). After 24 h or 2-year water storage, a microtensile bond strength test was performed.@*RESULTS@#In group A, the dentin surface was rough, the smear layer was thick, and the dentin tubule orifice detritus showed low embolism value. In group B, the dentin surface roughness decreased, the embolism proportion increased, and the smear layer became thin. The initial bonding strengths of CSA and MS in group A were significantly lower than those in group B (P0.05).@*CONCLUSIONS@#The properties of the smear layer and the types of self-adhesive resin cement used affected the bond strength and durability.
