<p><b>OBJECTIVE</b>To study the efficacy and safety of rituximab (RTX) in the treatment of idiopathic thrombotic thrombocytopenic purpura (ITTP).</p><p><b>METHODS</b>Among 17 ITTP patients, nine cases of the RTX group were administrated with RTX plus plasma exchange (PEX) and steroids. Eight cases of the control group received PEX plus steroids±other immune inhibitors. Patients received RTX 375 mg/m², 1 per week for 4 weeks. The laboratory parameters, including hemogram, LDH, ADAMTS13 activities and its inhibitors, and the ratio of B lymphocytes in peripheral blood were monitored. The number of PEX, total plasma volumes, remission time, relapse ratio and adverse effects in both groups were compared.</p><p><b>RESULTS</b>The median number of PEX/median total plasma volumes in the RTX and control group were 5(2-8)/9.6(4.0-15.4) L and 6(4-9)/11.2(7.5-14.6) L, respectively. Patients in the RTX and control group achieved hematologic remission at the median time of 15(5-20) days and 22(7-36) days, respectively. And the median time of immunological remission in the two groups was 2(2-8) and 2(2-4) weeks, respectively. ADAMTS13 activities increased significantly after 2 weeks in both two groups. There was no relapse in the RTX group, while 4 patients relapsed in the control group. The percentage of B lymphocytes in peripheral blood obviously deduced one week after first dose of RTX infusion compared with the level before treatment [(2.19±5.11)% vs (18.39±7.15)%, P<0.001], and began to gradually increase 9 months later. Severe adverse events were not observed in RTX group during the therapeutic procedure and follow-up, but one patient, who had sustained immunologic remission, died of severe pneumonia 7 months later.</p><p><b>CONCLUSION</b>In the treatment of ITTP, RTX in conjunction with PEX and steroids appeared to be a safe and effective therapy, with fast and sustained remission in hematology and even in immunology, with lower relapse rate and less adverse effects. But patients needed to be paid attention to prevent and treat infectious events in time.</p>

ABSTRACT
Objective To explore the diagnostic value of protein induced by vitamin K absence or antagonist-Ⅱ (PIVKA-Ⅱ) in non-infant with acquired deficiency of vitamin K-dependent coagulation factors (ADVKCF).Methods PIVKA-Ⅱ levels were measured by ELISA in 50 patients with ADVKCF on day 0,3,7 after vitamin K treatment.Prothrombin time(PT),APTT,FⅡ ∶ C,FⅦ∶ C,FⅨ∶ C,and FⅩ∶ C were analyzed simultaneously.Twenty healthy subjects were enrolled as controls.Results The average level of PIVKA-Ⅱ in ADVKCF group was (3.83 ± 1.40) μg/L,while (1.30 ± 0.54) μg/L in the control group (P ＜ 0.05).The PIVKA-Ⅱ levels on day 0 and 3 did not show significant difference [(3.83 ± 1.40) μg/Lvs (3.79 ± 0.66) μg/L,P ＞ 0.05],but decreasing significantly on day 7 compared to the control group (P ＜ 0.05).The PIVKA-Ⅱ level was (3.78 ± 1.30) μg/L in patients receiving plasma transfusion,while (3.91 ± 1.49)μg/L in no-plasma-transfusion group (P ＞ 0.05).Coagulation factors Ⅱ,Ⅶ,Ⅸ and Ⅹ activity which decreased significantly before treatment returned to normal range after one week use of vitamin K,leading to complete correction of prolonged APTT and PT (＞ 100 seconds).Conclusions The PIVKAⅡ level in ADVKCF patients is significantly higher than that of healthy subjects within one week treatment of vitamin K,which is not influenced by plasma transfusion.This study suggests that PIVKA-Ⅱ is a more sensitive parameter than APTT,PT and the activity of coagulation factor,which could be a valuable factor in the early diagnosis of ADVKCF.
ABSTRACT
Objective To investigate the expression of Circulating tumor cells ( CTCs ) in peripheral blood cells of patients with different stages of Small-Cell Lung Cancer ( SCLC) ,and to evaluate its significance in early diagnosis of lung cancer metastasis.Methods Thirty-five patients with SCLC ( 12 in limited stage and 23 in extensive stage ) and 25 patients with benign lung disease were recruited at the Shanghai Changhai Hospital from April 2011 to April 2013.Samples were prepared from 7.5 ml peripheral venous blood and collected in CellSave tubes.The CTC counts were determined using CellTracks AutoPrep fluorescence scanning system according to the manufacturers′instructions.The expression of CTCs in peripheral blood of SCLC patients and benign lung disease patients were analyzed.The expression of CTCs in different stages of SCLC was measured and compared.Furthermore, samples were prepared from 2 ml peripheral venous blood by centrifugation.The serum levels of NSE Neuron specific enolase were measured.The relationship between the expression of CTC and NSE was analyzed.Results CTCs positive rates in SCLC were significantly higher than in benign lung disease controls [ Positive rates of CTC≥1 were 80.0%and 12.0%(χ2 =27.003,P<0.000 1),CTC≥5 were 51.4%and 0 (χ2 =18.367,P<0.000 1), CTC≥10 were 34.3%and 0(χ2 =10.714,P<0.001),CTC≥50 were 17.1 and 0(P=0.036,P<0.05), respectively ].CTCs positive rates in SCLC extensive stage were significantly higher than limited-stage [Positive rates of CTC≥1 were 58.3% and 91.3%(P=0.033,P<0.05), CTC≥5 were 65.2% and 25.0%(P=0.035,P<0.05), respectively].The expression of CTCs was significantly correlated with NSE (r=0.743 7, P<0.000 1).Conclusion The expression of CTC in SCLC patients is significantly higher than those in control group , and is closely related to clinical stages , which may provide new clues to early predicting of SCLC metastasis and deterioration.
