Objective:The clinicalpathological features of TAFRO syndrome were analyzed to clarify the similarities and differences between TAFRO syndrome and autoimmune diseases and to establish differential diagnosis.Methods:Six patients diagnosed with TAFRO syndrome in Shanxi Bethune Hospital from January 2014 to March 2022 were collected. The clinical, examination, pathology and treatment of TAFRO syndrome were analyzed and compared with autoimmune diseases, especially systemic lupus erythematosus and Sj?gren′s syndrome.Results:Among the 6 patients, 4 were males and 2 were females, with an average age of (57.5 ±9.8) years. All the 6 patients had fever, edema (including chest and abdominal effusion and systemic edema), thrombocytopenia (3 main criteria) and more than 2 secondary criteria.ESR and CRP were significantly elevated in 6 patients. There were 1 case of elevated IgA and IgG (IgA 4.10 g/L, IgG19.05 g/L), 1 case of elevated igg (IgG 19.33 g/L), 3 cases of normal and 1 case of undetected. Serum IgG4 was negative in 4 cases and undetected in 2 cases. Autoantibodies: 4 cases were ANA positive, including 1 case with anti-SSA/Ro52(+), anti-SSA/Ro60(+), anti-SSB (+), 1 case with anti-SSA /Ro60(+), and 2 untested. Bone marrow cytological examination was performed in 6 cases, all of which showed active hyperplasia, 2 cases showed elevated megakaryocytes, and 1 case was accompanied by interstitial fibrosis. Pathological examination of lymph nodes: 5 cases were consistent with Castleman′s disease, and 1 case was suggestive of reactive hyperplasia of lymph nodes. Conclusion:Although the diagnostic criteria of TAFRO syndrome should exclude autoimmune diseases, TAFRO syndrome and autoimmune diseases can coexist, and the connective tissue disease complicated with TAFRO syndrome has its specific clinical characteristics and treatment plan, which needs to be identified clinically.

Objective To investigate the diagnostic value of multiparametric MRI in early prostate cancer(PCa) based on PI-RADS version 2.Methods 27 surgically-proved early PCa patients were collected in this retrospective study.T2WI,DWI and DCE were evaluated by two blinded radiologists.By 12 sub-region classification method the possibility of the presence of cancer at each sub-region was scored according to the PI-RADS V2.The receiver operating characteristic (ROC) curve was used to analyze the diagnosic efficacy of the following 4 protocols:T2WI alone(protocol 1),T2WI+DWI(protocol 2),T2WI+DCE(protocol 3),T2WI+DWI+DCE(protocol 4).The sensitivity,specificity and accuracy for each protocol were calculated.The average scores of cancerous sub-regions and non-cancerous sub-regions were calculated and the independent sample t test was used to compare the four protocols.Results 324 sub-regions were analyzed in 27 early PCa patients and then divided into 119 cancerous sub-regions and 205 non-cancerous sub-regions,including 64 peripheral zone cancerous sub-regions and transition zone cancerous sub-regions.In protocol 1-4, the average scores of cancerous sub-regions in orderwere 3.13±1.19,3.27±1.15,3.28±1.23, 3.33±1.16,respectively.Non-cancerous sub-regions's scores in order were 1.98±0.90,1.91±0.91, 2.03±0.99,1.94±0.96 respectively and there were significant differences among each protocol (P<0.05).The area under the ROC curve of the 4 protocols for region-based analysis were displayed in descending order: protocol 4 (0.819), protocol 2 (0.810), protocol 3 (0.772), protocol 1 (0.765) and there were no significant differences between any two protocols (P>0.05).In four protocols, the sensitivity in order were 45.40%, 56.30%, 59.70%, 61.34%, while the specificity in order were 95.10%, 96.10%, 89.80%, 96.60%, and the accuracy in order were 76.85%, 81.48%, 78.70%, 83.65%.Conclusion Multiparametric MRI can improve the diagnostic accuracy for the detection of early PCa, and T2WI+DWI+DCE is with the highest value.The PI-RADS V2 system is a better semi quantitative method for evaluation of early PCa.

Objective To evaluate the value of T2WI scores for diagnosis and differential diagnosis of transition zone prostate cancer(PCa).Methods T2WI of 43 cases of transition zone PCa and 91 cases of benign prostatic hyperplasia(BPH) were analyzed retrospectively.Transition zone T2WI signs were divided into the main signs and the secondary signs, which were given different scores and were evaluated separately by receiver operating characteristic (ROC) curve for their diagnostic value.Results In a total of 11 scores sections (-1-10), as the increase of scores, the sensitivity of transition zone PCa was decreased while the specificity and positive predictive value were both increased.According to the ROC curve, when the critical value of scores≥4.5, the sensitivity, specificity, negative predictive value, and the accuracy were 81%,73.3%,90.9%,70.4% respectively.When the scores ≥8.5,the specificity and positive predictive value were both 100%.When the scores ≥0.5 and ≥1.5,the negative predictive value were 100%.Conclusion T2WI scores can quantitatively analyze the transition zone PCa,which has an important value to improve the clinical diagnosis and guide treatment.

OBJECTIVETo establish a method for isolation, cryopreservation and recovery of the highly viable human peripheral blood monomuclear cells (PBMNCs) so as to achieve the long-term preservation of PBMNCs.

METHODSA total of 80-100 ml peripheral blood were collected from the healthy volumteers aged over 50 years old. The PBMNCs were isolated by the Ficoll density gradient technique and cryopreserved gradually by program control method in liquid nitrogen freezer of -196 °C. The serum-free medium and autoloqous plasma medium were test for preservation of PBMNCs. The cell viability was assessed at time point of 1, 2, 4, 8, 12 and 24 months after thawing. Finally, the proliferation ability, purity and cytotoxicity were compared between the autologous immune lymphocytes (AIL) induced from cryopreserved PBMNCs and AIL as control from fresh PBMNCs.

RESULTSAfter separating, the cell viability was 99.6%±0.4%, and the recovery rate of lymphocytes was 58.4%±6.52%. The cell recovery rate of lymphocyte was 89.7%±3.82% at 24 months. The quality assurance program was reliable within 2 years of running. The AIL cells induced with cryopreserved PBMNCs were not significantly different from those induced from fresh PBMNCs in terms of proliferative action, purity and cytotoxicity(CD3(+)CD8(+) ≥45%,CD3(+)CD56(+) NKT≥10%,CD4(+)CD25(+) NKT≤10%).

CONCLUSIONManual separation of lymphocytes in vitro can get enough high-quality PBMNCs. The long-term cryopreserved PBMNC still maintain their high viability. The reinfusion of the clinical autologous immune cells would be advantageous for early tumor immunotherapy. Human AIL induced from cryopreserved PBMNC maintain their anti-tumor ability. These findings have the important implications for the application of these cells to adoptive cellular therapy.
