OBJECTIVE:
To compare the effect of Sheng-Xue-Xiao-Ban Capsule (SXXBC) and indirubin to the peripheral platelets of the Idiopathic thrombocytopenic purpura (ITP) model mouse.
METHODS:
The ITP mouse model was established by the method of passive immunization. SXXBC and indirubin were used for intervention treatment. Then the hemorrhagic phenomena of ITP mice were observed and the numbers of peripheral platelets, hemoglobin and white blood cells, bone marrow megakaryocytes and their classification and coagulation function were detected and compared.
RESULTS:
The improvement rate of hemorrhage in SXXBC group was 40% for small dose, 60% for medium dose and 80% for high dose, while the improvement rate of hemorrhage in indirubin group was 30% for small dose, 50% for medium dose and 60% for high dose. There was no statistically significant difference in the improvement rate of hemorrhage between the two groups (P>0.05). Compared with the model control group, PLT and Hb increased in different doses of SXXBC and indirubin group 4th-8th day after drug intervention (P<0.05, 0.01). However, there was no significant difference between the different doses of SXXBC group and indirubin group (P>0.05). Compared with the model control group, the WBC in each group was significantly lower (P<0.05, 0.01) on the 4th-8th day after drug intervention; However, there was no statistical significance between the two groups of SXXBC and indirubin (P>0.05). Compared with the model control group, the total number of megakaryocytes in each treatment group were decreased (P<0.05, P<0.01), in which the number of primary megakaryocytes in the large and medium dose groups of SXXBC and indirubin were decreased (P<0.05, 0.01), and the number of juvenile megakaryocytes in the large dose group of SXXBC and indirubin were also decreased (P<0.05). The number of granular megakaryocytes were decreased in each intervention groups (P<0.05, 0.01), and the number of thromocytogenic megakaryocyte was increased in the high and medium dose groups of SXXBC and indirubin (P<0.01). The time of prothrombin was shortened in the high and medium dose groups of SXXBC and indirubin (P<0.05), and the fibrinogen (FIB) content in the high and medium dose groups of SXXBC was close to that of the normal control group.
CONCLUSION
Both of the SXXBC and the indirubin standard all show good hemostatic effects. Indirubin shows a positive effect on increasing the peripheral platelet and hemoglobin in ITP model mice, regulating the immune response, reducing the total number of bone marrow megakaryocytes, increasing the thromocytogenic megakaryocyte, and increasing coagulation function.

To investigate contribution of soluble interleukin-2 receptor (SIL-2R) to the clinical progress of idiopathic thrombocytopenic purpura (ITP), SIL-2R levels were measured in the plasma of 34 patients and 34 normal controls with double antibody sandwich ELISA. The cohort consisted of 12 patients with chronic ITP, 15 with acute ITP and 7 with ITP in remission. The results showed that the mean SIL-2R level of chronic ITP group was significantly higher than those of both the control and acute ITP group (P < 0.001 and P < 0.01, respectively). The SIL-2R level of 7 cases in remission, however, was not significantly different from that of normal controls. Furthermore, the plasma levels were dramatically lowered in patients responsive to VLAP regimen (vincristine, L-imidazole, antaisu and prednisone), and those were not evidently decreased in unresponsive patients. It was concluded that T cell activation may play a role in the development of ITP, and further, the level of plasma SIL-2R might predict the prognosis of ITP.

OBJECTIVETo identify the relationship between the expression of alpha and beta-isoforms of glucocorticoid receptors (GR) in peripheral blood mononuclear cells (PBMC) and glucocorticoid resistance in children with idiopathic thrombocytopenia purpura (ITP).
METHODSReal-time PCR was used to detect the expression of GR alpha and GR beta mRNA in PBMC from 30 children with ITP (glucocorticoid-sensitive, n=18; glucocorticoid-resistant, n=12) and 10 healthy children (control group). Enzyme immunoassay was used to measure plasma levels of total glucocorticoids.
RESULTSThere were no significant differences in PBMC GR alpha mRNA levels among the glucocorticoid sensitive, the glucocorticoid-resistant and the control groups. Compared with the glucocorticoid-sensitive and the control groups, the expression of GR beta mRNA in the glucocorticoid-resistant group was significantly up-regulated (p<0.01). Plasma total glucocorticoids level in the glucocorticoid-resistant group was found to be much higher than that in the glucocorticoid-sensitive and the control groups (p<0.01).
CONCLUSIONSThe up-regulated expression of GR beta mRNA may associated with glucocorticoid resistance in children with ITP.

OBJECTIVETo investigate the clinical effect and safety of anti-D immunoglobulin (anti-D) in the treatment of children with newly diagnosed acute immune thrombocytopenia (ITP) through a Meta analysis.
METHODSPubMed, EMBASE, Cohrane Library, Ovid, CNKI, and Wanfang Data were searched for randomized controlled trials (RCTs) published up to April 2017. Review Manager 5.3 was used for the Meta analysis.
RESULTSSeven RCTs were included. The Meta analysis showed that after 72 hours and 7 days of treatment, the intravenous immunoglobulin (IVIG) group had a significantly higher percentage of children who achieved platelet count >20×10/L than the anti-D group (P<0.05). There were no significant differences in platelet count after 24 hours, 72 hours, and 7 days of treatment between the anti-D (50 μg/kg) group and the IVIG group (P>0.05), and there were also no significant differences in platelet count after 24 hours and 7 days of treatment between the 50 μg/kg and 75 μg/kg anti-D groups (P>0.05). The anti-D group had a significantly greater reduction in the hemoglobin level than the IVIG group after treatment, but did not need transfusion. No children in the anti-D group or the IVIG group experienced serious adverse reactions.
CONCLUSIONSIntravenous injection of anti-D may have a similar effect as IVIG in improving platelet count in children with acute ITP, but it may be slightly inferior to IVIG in the rate of platelet increase after treatment. The anti-D dose of 50 μg/kg may have a similar effect as 75 μg/kg. The recommended dose of anti-D for treatment of ITP is safe.

The aim of this study was to investigate the circulating levels of IL-11 in the patients with chronic idiopathic thrombocytopenic purpura (CITP), and its significance, and to evaluate the curative effect of rhIL-11 on CITP. The level of IL-11 in patients with CITP was determined by ELISA before and after treatment, respectively. 1.5 mg of rhIL-11 were injected subcutaneously, once a day, continuously for 14 days as one course, treatment time 1 - 2 courses as total. The results showed that the higher blood IL-11 level was found in CITP patients than that in controls (P < 0.01) and during the course of treatment the number of platelets in peripheral blood of patients with CITP parallelled to the level of IL-11. The platelet counts were obviously increased in all CITP patients after rhIL-11 treatment. It is concluded that the serum level of IL-11 in patients is correlated to the number of platelets in patients. rhIL-11 can be used as an effective treatment for CITP.

In order to determine the curative effect of multiglycosidorum Tripterygii and prednisone for treatment of children with chronic refractory idiopathic thrombocytopenic purpura (ITP), a total of 28 patients had been treated with multiglycosidorum Tripterygii and prednisone. Multiglycosidorum Tripterygii was given at a dose of 1 mg/kg body weight per day and the prednisone was given at a dose of 0.5 mg/kg body weight per day for two consecutive months. Bone marrow examination and blood platelet associated immunoglobin G (PAIgG) measurement were performed during the treatment. The results showed that in 21 patients acquired effectiveness, of whom, according the common criteria, 9 patients achieved curative effective, 7 achieved significant effectiveness and 5 effective. 7 patients did not achieve effectiveness. There were no serious side effects associated with therapy. The number of proplatelets on bone marrow smears was increased and the titers of IgG to platelet were restored to normal range in patients achieving remission. In conclusion, combination of multiglycosidorum triptergii with prednisone is effective and safe for treatment of chronic refractory idiopathic thrombocytopenic purpura in children.

This study was purposed to investigate the effect of high-dose dexamethasone (DXM) on function and Toll like receptor 9 (TLR-9) expression of plasmacytoid dendritic cells (pDC) in peripheral blood of patients with immune thrombocytopenic purpura (ITP). 15 newly diagnosed patients with ITP received high dose DXM at single daily doses of 40 mg for 4 consecutive days. The peripheral blood plasmacytoid dendritic cells from 13 remission patients and 15 normal controls were separated by immunomagnetic beads and then induced by CpG-OND2216. 24 h later, the levels of IFN-α, IL-6 and TNF-α in the supernatant were detected by enzyme linked immunosorbent assay (ELISA). The expression of TLR9 mRNA of pDC was detected by real-time quantitative PCR. The results indicated that the levels of IFN-α, IL-6 and TNF-α produced by pDC in ITP patients were significantly higher than those in normal controls (P < 0.05). After high dose DXM treatment, the levels of IFN-α, IL-6 and TNF-α decreased without significant difference compared with normal controls (P > 0.05). The expression of TLR9 mRNA in pDC of untreated patients was significantly higher than that in control group (P < 0.05), and significantly reduced after treatment without difference from that in control group (P > 0.05). It is concluded that pDC may play an important role in ITP by their TLR9 and secreted cytokines; dexamethasone may down regulate the expression of TLR9, inhibit pDC function, and thus play a therapeutic role.

OBJECTIVETo evaluate the impact of platelet membrane glycoprotein (GP)-specific autoantibodies on high-dose dexamethasone therapy in patients with idiopathic thrombocytopenic purpura (ITP).
METHODSModified direct monoclonal antibody immobilization of platelet antigen assay (MAIPA) was used to detect platelet GPIIb/IIIa and/or GPI b specific autoantibodies. All patients received oral dexamethasone 40 mg/d for 4 days.
RESULTSThe response rate of high-dose dexamethasone in GPIIb/IIIa and/or GPIb specific autoantibody-negative patients was significantly different from that of antibody-positive patients (P<0.05). The response rate of GPIIb/IIIa specific autoantibody-positive patients was lower than that of antibody-negative patients (P<0.05). GPIb specific autoantibody had no significant impact on the efficacy of high-dose dexamethasone (P>0.05).
CONCLUSIONPlatelet membrane GPIIb/IIIa-specific autoantibody can be a potential negative indicator for ITP patients'response to high-dose oral dexamethasone.
