Objective To explore the efficacy and immune reconstitution of autologous peripheral blood stem cell transplantation (APBSCT) in the treatment of refractory autoimmune thrombocytopenia purpura (ITP). MethodsOne patient with refractory ITP was treated with APBSCT, the effectiveness and the process of immune reconstitution were analyzed retrospectively. Results The case was mobilized by cyclophosphamide (CY) plus G-CSF and 4.7?106/kg CD34+ cell was gained totally. Neutrophil and platelet were engrafted at 11th and 12th day without severe complications following the conditioning of TBI and CY. Although the each phenotype of the peripheral blood lymphocytes recovered gradually 6 months after the transplant,inverted CD4/CD8 ratio exited and memory T cell was improved much earlier than naive T cell. The platelete count was constantly over 100?109/L and the patient was in complete remission after a follow-up of 31 months.Conclusion APBSCT is a potential approach in the treatment of refractory ITP.

OBJECTIVETo assess the association of copy number variations (CNVs) of exon 11 of IL-23 receptor gene with susceptibility to active pulmonary tuberculosis among Chinese Uygurs.
METHODSIn this study, 250 subjects with active pulmonary tuberculosis (PTB) and 250 normal controls were recruited. A paired case-control study was conducted in the Chinese Uygur population in Xinjiang and the CNV of IL-23R was analyzed using Taqman real-time PCR.
RESULTSThe study showed that the frequencies of different copy number in exon 11 of IL-23R between PTB and control groups were statistically significant (χ(2)=13.35, P<0.01). There were significant difference in CNV of exon 11 in IL-23R between PTB patients and controls (χ(2)=14.95, P<0.01, OR=2.875, 95%CI: 1.655-4.994). The increase of copy number in exon 11 of IL-23R showed significantly different between PTB and control groups (χ(2)=10.475, P=0.0012, OR=2.611, 95%CI: 1.437-4.744).
CONCLUSIONThe CNV of exon 11 in IL-23R is associated with PTB in the Chinese Uygur population. The increase of the copy number in exon 11 of IL-23R may be a risk factor for PTB in Chinese Uygurs.

Objective:
To explore the clinical characteristics, treatment, and prognosis of patients with blastic plasmacytoid dendritic cell neoplasm.
Method:
Clinical records of 6 patients diagnosed with blastic plasmacytoid dendritic cell neoplasm in our hospital from January 2008 to May 2016 were collected and retrospectively analyzed.
Results:
Six patients manifested with initial symptoms of skin lesions, other common symptoms included bone marrow involvement (5/6) , lymphadenectasis (4/6) , splenomegaly (4/6) , and hepatomegaly (3/6) . In addition, extra-nodal involvement except skin was also observed, including breast (1/6) , maxillary sinus (1/6) , vertebrae (1/6) , and central nervous system (1/6) . Characteristic immunophenotype, CD4, CD56, and CD123 were all positive. All these patients were treated with acute lymphoblastic leukemia type (ALL-type) chemotherapy and complete remission (CR) were reached in 4 patients. The median follow-up was 9.5 (7-37) months, median progression free survival was 7 months; while median overall survival was 9 months. A total of 3 patients died during the follow-up, which were all happened in the first year after diagnosis, and all resulted from the relapse or disease progression.
Conclusion
Blastic plasmacytoid dendritic cell neoplasm is highly aggressive, in which the skin lesions are always manifested as initial symptoms, and bone marrow involvement, lymphadenectasis, splenomegaly, and hepatomegaly is also common. Characteristic immunophenotype include the positivity of CD4, CD56, and CD123. Effective and standard therapy is limited in this disease, which indicates the poor prognosis.
