Objective@#To investigate the incidence and clinical features to probe the risk factors of hemorrhagic cystitis (HC) in children and adolescents with hematological diseases post haplo-hematopoietic stem cell transplantation (haplo-HSCT) .@*Methods@#Medical records of 62 children and 27 adolescents with hematological diseases treated with haplo-HSCT between 2015 and 2016 were analyzed.@*Results@#Of 89 cases (56 boys and 33 girls) , 44 patients were diagnosed with ALL, 33 AML, 3 AHL and 9 MDS. HC occurred in 32 of the 89 patients with an incidence of 36%, including 6 with grade Ⅰ, 16 with grade Ⅱ, 8 with grade Ⅲ, 2 with grade Ⅳ HC, respectively. The median time of HC onset was 25 days (range 2-55 days) after haplo-HSCT with the median duration as 19 days (range 3-95 days) , all of them were cured. The incidence of HC was lower in the group of children than that in the group of adolescents (27.4% vs 55.6%, χ2=6.466, P<0.05) , and the incidence of HC was higher in the group of patients who were ≥5 years old than that in the group of patients who were <5 years old (0 vs 34%, χ2=4.043, P<0.05) .@*Conclusion@#HC is one of common complications in children and adolescents with hematological diseases post haplo-HSCT, older age was associated with increased mortality.

Objective To compare the safety and efficacy of direct and remedial rotational atherectomy in the treatment of heavily calcified coronary artery lesions.Methods We retrospectively reviewed 58 patients admitted in the Shanghai Chest Hospital and Liaocheng People Hospital from May 2012 to July 2015 who had received stent implantation and rotational atherectomy.The 58 patients were divided into two groups which were the direct atherectomy group (n =27) and the remedial atherectomy group (n =31).General clinical date,lesion and procedural characteristics,intraoperative complications,in-hospital and follow-up MACCE were compared between the two groups.Results There were no differences between the two groups in general clinical date intraoperative complications,amount of contrast agent used,proceduraltime,rates of in-hospital and follow-up MACCE.Nevertheless,compared with the direct artherectomy group,the remedial group had more number of balloon dilations during procedure [3 (1,5) vs.2 (1,2),P < 0.001] and higher peak cardiac troponin levels [1.1 (0.3,3.0) μg/L vs.0.5 (0.1,2.3) μg/L,P =0.032].Conclusions Remedial rotational atherectomy with drug-eluting stent had the same safety and efficacy as direct atheretomy with drug-eluting stent in treating patients with heavily calcified coronary lesions.It is reasonable and safe to transform routine PCI to remedial rotational atherectomy when the 2.0 mm semi compliant balloon or/and 2.5 mm non-compliant balloon cannot pass through or dilate the lesions.

Objective To study the relationship between the cytogenetic and the prognosis in children with acute lymphoblastic leukemia (ALL).Methods RT-PCR was used to detect the common fusion gene,chromosome number and structure in 103 children with ALL.The effects of chromosome and fusion gene changes on treatment response and survival time were analyzed.Resuts Among 103 children with ALL,52 cases had normal gene number and no fusion gene,and 51 cases had fusion gene,including 22 cases with TEL-AML1 positive,10 cases with bcr-abl positive,11 cases with E2A-PBX1 positive,2 cases with MLL-AF4 positive,3 cases with HOX11 positive,1 case with SIL-TAL1,1 case with dupMLL and 1 case with TLS-ERG.The average survival time of bcr-abl group was shorter than that of non-fusion gene group,TEL-AML1 group and E2A/PBX1 group respectively,and there were significant differences [(16.5±3.8) months vs (34.6±1.7) months,(31.6±1.4) months,(34.5±3.3) months,all P < 0.05],but there was no significant difference between bcr-abl group and other fusion gene group [(12.8±1.5) months,P >0.05].The average survival time of non-fusion gene group had no significant differences compared with TEL-AML1 group and E2A-PBX1 group(both P > 0.05),but had significant differences with other fusion gene group (P < 0.05).There were 18 patients with abnormal chromosome number and structure,including 4 cases with diploid,14 cases with super diploid.The patients with diploid had shorter survival time [(19.8±4.8) months vs (37.5 ±2.2) months,x2 =7.375,P =0.007] and were easier to relapse than ones with super diploid.The average survival time of patients with different white blood cell count and lactate dehydrogenase levels had significant differences (both P < 0.05).Conclusion Detection of cytogenetics and chromosome fusion genes can be used to determine the prognosis and outcome of children with ALL,which has important guiding significance for the realization of individualized treatment.

<p><b>INTRODUCTION</b>This study aimed to examine the long-term clinical outcomes of coronary fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) in a real-world population in an Asian tertiary centre.</p><p><b>MATERIALS AND METHODS</b>All patients who underwent FFR measurement for intermediate coronary lesions in our centre from June 2002 to December 2009 were enrolled. A threshold of FFR ≤0.75 was used for revascularisation. All the patients were prospectively followed-up for major adverse cardiac events (MACE) of death, myocardial infarction (MI), target vessel revascularisation (TVR) and stent thrombosis.</p><p><b>RESULTS</b>Based on FFR measurement, 368 (57%) patients were treated medically while 278 (43%) underwent revascularisation. At a mean follow-up duration of 29.7 ± 16 months, 53 (14.4%) patients in the medical therapy group and 32 (11.5%) patients in the revascularised group experienced MACE (P = 0.282). There were no statistical differences in all the clinical endpoints between the 2 groups.</p><p><b>CONCLUSION</b>Medical therapy based on FFR measurement is associated with low incidences of MACE at long-term follow-up.</p>

Objective To evaluate the clinical features of in-stent restenosis after drug eluting stent (DES) implantation and investigate the relationship between different patterns of DES restenostic lesions and long-term prognosis.Methods All scoronary heart disease patients who underwent repeated pereutaneous coronary intervention (PCI) for DES in-stent restenosis from September 2006 to December 2009 were enrolled.All patients were divided into focal group and non-focal group according to the pattern of restenosis.All patients were prospectively followed up for major adverse cardiovascular event (MACE) including death,repeat PCI and myocardial infarction.Results Totally 88 patients (40 with focal restenosis,48 with non-focal restenosis) were enrolled.There were no significant differences between two groups in age,gender,risk factors,clinical presentation and medical therapy (P > 0.05).Compared with that in focal group,the patients in non-focal group had a higher portion of in-segment restenosis [58.3% (28/48) vs.12.5%(5/40),P< 0.01],higher stenosis rate [(78.1 ± 10.0)% vs.(70.0 ± 9.7)%,P < 0.01],more need for another DES[81.2%(39/48) vs.17.5%(7/40),P< 0.01],and longer stent implanted [(25.0 ± 7.0) mm vs.(17.4 ±3.4) mm,P <0.01].After following up for (2.2 ± 1.0) years,there were no significant differences between two groups in MACE and each component (P > 0.05),however,compared with that in focal group,there was a trend of increase in MACE in non-focal group[22.9%(11/48) vs.10.0%(4/40),P=0.092].Conclusion It suggests that patients with non-focal restenosis have a more severe lesion angiographically,which usually results in another DES implanted,and has a worse long-term prognosis.

Objective To evaluate the clinical significance of minimal residual disease (MRD)detecion in ALL-B of children by flow cytometric (FCM).Methods 52 cases of children with ALL-B were performed bone marrow MRD by FCM analisis after induction therapy,3 moths therapy,and 6 moths therapy.After that,MRD detection was performed every 6 months. According to disease risks, three group were categorized,standard risk (SR),imidiete risk (IR) and high risk(HR).Results After 6 months,SR groups MRD positive cases were 4/21(19 %),IR groups MRD position cases were 8/23 (35 %),HR groups MRD position cases were 5/8 (63 %).9 cases relapsed in all 52 patients.There were significant differrence in replased rate between the positive and negtive MRD (P<0.001). Conclution The dynamic detection of MRD by FCM can be used to evaluate the therapeutic effect and prognosis of children with ALL-B. It is also useful in adjusting treatment strategy and for following up in children with ALL.
