This study was purposed to assess the efficacy of stanozolol for treatment of childhood patients with acquired non-severe aplastic anemia (NSAA). The records of 114 children with acquired NSAA treated in hospital between January 1996 and January 2009 were analyzed retrospectively. All patients received stanozolol with the dose of 0.1 mg/(kg·d). Some patients were treated with supportive care. The incidence and the risk factors of progression severe aplastic anemia (SAA) including gender, age, absolute neutrophil count, absolute reticulocyte count, dependent or independent of transfusion, the ratio of granulocytes and erythrocytes were evaluated. The results indicated that at a median follow-up of 52 months (range 5 - 181), 6 patients (5.3%) progressed into SAA, 93 (81.6%) remained in NSAA, and 15 (13.2%) had complete remission. Patients with dependent of transfusion (platelet count < 10 × 10(9)/L and/or haemoglobin < 70 g/L) have higher risk to progress into SAA (19.2% vs 1.1%) (p = 0.016); patients with lower absolute neutrophil count (ANC) (< 0.8 × 10(9)/L) or with lower absolute reticulocyte count (ARC) (< 40 × 10(9)/L) at diagnosis have higher risk to progress into SAA (8.1% vs 0%) (p = 0.029); (9.1% vs 1.7%) (p = 0.034); Those patients with lower ANC (ANC < 0.8 × 10(9)/L) and lower ARC (ARC < 40 × 10(9)/L) have higher risk into progress to SAA (19.2% vs 1.1%) (p = 0.016). It is concluded that NSAA patients treated with Stanozolol progress into SAA with the rate of 5.3%. Those patients with dependent of transfusion or ANC < 0.8 × 10(9)/L or/and ARC < 40 × 10(9)/L have higher risk of progress into SAA.

OBJECTIVETo evaluate the effect of combined use of stanazolol (ST) on the final adult height (FAH) in girls with idiopathic central precocious puberty (ICPP) and apparently decreased linear growth during gonadotropin-releasing hormone analog (GnRHa) therapy.

METHODSixty-three girls with ICPP and decreased velocity of growth of height (HV<4 cm/yr) during GnRHa therapy were divided into 3 groups based on the following types of interventions:group 1 (n = 20), GnRHa+ST [25-30 µg/(kg·d) every 3-month followed by 3-month discontinuation], group 2 (n = 21), GnRHa+recombinant human growth hormone [rhGH, 1-1.1 U/(kg·w)], group 3 (n = 22), GnRHa alone.HV, the advancement of bone age (BA) for chronological age (CA) (ΔBA/ΔCA) and FAH were compared among groups.

RESULT(1)Total duration of ST combination therapy was (12.22 ± 3.62) months, while total duration of combination of rhGH was (13.22 ± 6.80) months. (2)HV increased significantly in both group 1 [ (2.79 ± 0.60) cm/yr vs. (6.27 ± 1.98) cm/yr, P < 0.01] and in group 2 [(2.80 ± 0.50) cm/yr vs. (6.25 ± 1.98) cm/yr, P < 0.01] during combined therapy, but maintained at low levels in group 3 [(3.95 ± 1.10) cm/yr vs. (3.34 ± 0.95) cm/yr, P > 0.05].No significant differences of ΔBA/ΔCA were found among the three groups [0.25(0.11∼0.28), 0.22(0.15∼0.31),0.19(0.10∼0.32), P > 0.05]. (3)FAH was significantly higher than predicted adult height (PAH) before combined therapy, as well as higher than target height (THt) in both group 1 [(156.25 ± 2.90) cm vs. (150.78 ± 3.70) cm, P < 0.01, (156.25 ± 2.90) cm vs. (153.94 ± 2.62) cm, P < 0.01], and in group2 [ (157.33 ± 4.69) cm vs. (152.61 ± 3.92) cm, P < 0.01, (157.33 ± 4.69) cm vs. (154.39 ± 4.72) cm, P = 0.01].In group 3, FAH was similar to PAH [(153.88 ± 2.6) cm vs. (152.54 ± 5.86) cm, P > 0.05], and was less than THt [(153.88 ± 2.6) cm vs. (155.60 ± 4.52) cm, P = 0.02]. (4)In girls treated with ST, no hirsutism, clitorism or hoarse voice was recorded.No polycystic ovary syndrome was found by B-mode ultrasound.

CONCLUSIONIntermittent combined use of low dose ST therapy can increase HV and thus improve FAH in girls with ICPP and apparently decreased linear growth during GnRHa therapy.

OBJECTIVETo explore the therapy to further elevate the efficacy of the treatment of chronic aplastic anemia (CAA).

METHODSForty-five patients with CCA were assigned into two groups, the 26 patients in the treated group were treated by Shengxuening (a Chinese herbal preparation) and cyclosporin A (CsA), and the 19 patients in the control group were treated with androgen alone, with the therapeutic course lasting for over 3 months. Changes of peripheral blood picture, and the colony productivity of burst forming unit-erythroid (BFU-E), colony forming unit-erythroid (CFU-E) and colony forming unit-granulocyte macrophage (CFU-GM) in bone marrow were observed before and after 3 months treatment. The amount of erythrocyte and platelet infusion, frequency of infection, condition of hemorrhage and relevant death were also observed. The follow-up study was conducted for over half a year.

RESULTSThe total effective rate in the treated group was 84.6%, which was significantly higher than that in the control group (52.6%, P < 0.05). Levels of hemoglobin, reticulocyte, neutrophil and platelet increased after treatment in the treated group, as compared with those before treatment, with significant difference (P < 0.05), and the colony productivity of BFU-E, CFU-E and CFU-GM in bone marrow also got significantly increased (P < 0.01), and showed significant difference from those in the control group (P < 0.05).

CONCLUSIONShengxuening-assisting CsA therapy is an effective measure for treatment of CAA.

OBJECTIVETo observe the clinical efficacy of Qinghuang Powder combined with Chinese herbs for reinforcing Shen and strenghening Pi in treating myelodysplastic syndrome (MDS).

METHODSfifty-five patients with diagnosis fitting to MDS were treated with Qinghuang Powder and decoction for strengthening Pi and reinforcing Shen, in combination with Stanozololum.

RESULTSEleven patients (20.0%) out of the 55 were completely remitted (CR), the total effective rate being 74.5% (41/55 cases). By FAB typing, 9 (26. 5%) in the 34 patients of type RA/RAS were CR, with the total effective rate of 82.4% (28/34 cases), and in the 21 patients of type RAEB, 9.5% (2/21 cases) were CR with the total effective rate of 61.9% (13/21 cases), showing insignificant statistical difference between the two types (P > 0.05). By international prognostic scoring system (IPSS), the treatment was evaluated as CR in 10 patients, effective in 25 and ineffective in 11 in 36 patients of moderate risk group I , the responding numbers were 1, 4, 2 in 7 patients of moderate risk group II and 0, 3, 3 in 6 patients of high risk group, respectively, also showing insignificant difference between groups (P > 0.05). Levels of Hb, WBC and platelet significantly increased after treatment (P < 0. 05). By cytogenetics, the effective rate was 68.8% (11/16 cases) in patients with abnormal chromosome and 72.7% (24/33 cases) in those with normal chromosome, with insignificant difference (P > 0.05).

CONCLUSIONThe comprehensive therapy with TCM treatment for reinforcing Shen and dissolving stasis in dominance has a definite clinical effect in treating MDS, it was not significantly associated with FAB typing, IPSS score, and chromosome abnormality of patients.

OBJECTIVETo investigate the effect of Shenmai injection on chronic aplastic anemia patients and its mechanism.

METHODSixty-five chronic aplastic anemia patients were randomized into treatment group and control group. The patients of the treatment group were treated by injecting Shenmai injection and taking western medicine orally, those of the control group taking western medicine orally only, then the effect was evaluated. The concentration of tumor necrosis factor-alpha (TNF-alpha) in blood serum was detected and the apoptosis of bone marrow CD34+ cell was analysed by DNA ISEL technic before and after treatment.

RESULTThe effective rate of the treatment group and the control group was 63.6 % and 40.6 % respectively, the effect of the Shenmai injection on the treatment group was obviously better than that of the control group (P < 0.01). Before treatment, the concentration of TNF-alpha in blood serum and the apoptosis rate of bone marrow CD34+ cell of the chronic aplastic anemia patient were higher than normal (P < 0.01). After treatment, the concentration of TNF-alpha in blood serum of the treatment group decreased obviously (P < 0.01), and the apoptosis rate of bone marrow CD34+ cell of the treatment group also decreased (P < 0.05), which had significant difference compared with those of the control group (P < 0.05).

CONCLUSIONShenmai injection is efficient to chronic aplastic anemia. The mechanism is decreasing the concentration of TNF-alpha in blood serum and the apoptosis rate of bone marrow CD34+ cell.

OBJECTIVETo investigate the effects and the mechanisms of stanozolol (ST) on the proliferation, maturation and differentiation of in vitro cultured growth plate chondrocyte isolated from gonadotropin releasing hormone analogue (GnRHa)-treated adolescent rats, to study if ST mediates the proliferation of chondrocytes via the estrogen receptor alpha (ERalpha), androgen receptor (AR) and/or insulin-like growth factor-1 receptor (IGF-1R) and interactions of the two receptor and IGF-1R receptor signaling pathway, to investigate the mechanism of the biological effects in ST promoting bone growth/maturity at molecular level.

METHODThe rats were weaned at the end of 3 weeks and intramuscular injection of triptorelin of GnRHa preparations, qow x 2 was started. The rats were sacrificed at the end of 7 weeks, and then the tibiae growth plates were taken out with sterile procedure. The chondrocytes were obtained by two-time enzyme digestion method, and the experiments were carried out with the primary chondrocytes. Immunohistochemical staining of proliferating cell nuclear antigen (PCNA) and Western blot analysis were applied.

RESULTThe results of PCNA demonstrated that stanozolol enhanced the proliferation of the chondrocytes, time-course studies showed that the proliferation were maximally stimulated by stanozolol after 2 days of incubation and decreased again after longer periods of incubation. The expression of p-ERalpha, p-IGF-1R and p-extracellular-signal regulated kinase 1/2 (ERK1/2) increased with the incubation period of ST treatment, and reached the peak value at a certain time, and then gradually decreased. The expression of p-ERalpha, p-IGF-1R and p-ERK1/2 increased with the elevation of ST concentration, and reached the peak value at 10(-9) - 10(-8) mol/L, then gradually decreased. ST induced-p-ERalpha expression was partially blocked by ERalpha and mitogen-activated protein kinase kinase inhibitors. ST induced-p-IGF-1R expression was partially blocked by ERalpha and IGF-1R inhibitors. ST induced-p-ERK1/2 expression was partially blocked by mitogen-activated protein kinase kinase and IGF-1R inhibitors.

CONCLUSIONAs an androgen derivation, ST exerts its biological effects of promoting proliferation of the long bone growth plate chondrocytes via activating the classic ERalpha receptor pathway and mitogen-activated protein kinase pathway, and at the same time, by activation of IGF-1R. Both IGF-1R and ERalpha can promote "cross-talk" of two systems' receptor signal through mitogen-activated protein kinase signal pathway.

OBJECTIVETo observe the effect of Shenfu injection (SFI) and influence on T-lymphocyte subset, serum level of interferon-gamma(IFN-gamma), tumor necrosis factor-alpha(TNF-alpha), interleukin-2(IL-2) in patients with chronic aplastic anemia (CAA) based on treating with stanozol and cyclosporin A.

METHOD60 patients with CAA were randomly divided into two groups, 30 patients in the SFI group were treated with SFI (100 mL which contains Ginsenoside 0.8 mg x mL(-1) and aconitine 1.8 microg x mL(-1) by adding it in 500 mL of 5% glucose every day) plus stanozol and cyclosporin A and 30 patients in the control group treated with slanozol and cyclosporin A alone for 2 months. The clinical efficacy was observed. The change of T-lymphocyte subset analyzed by flow cytometry and the levels of serum IFN-gamma, TNF-alpha, IL-2 measured with ELISA method were also observed before and after treatment.

RESULTAfter treatment, the total effective rate of the SFI group was higher than that in the control group, but it did not showing significant difference. The CD4/CD8 levels were significantly increased (1.76+/-0.49, P< 0.01) and CD8 levels were significantly lowered (22.57+/-6.30, P < 0.01) in the SFI group after treatment. Serum levels of lFN-gamma, TNF-alpha and IL-2 were lower in both groups, and the level of TNF-alpha and IL-2 in the SFI group (0.710+/-0.213) ng x L(-1) and (0.639+/-0.247) ng x L(-1) was significantly lowered than that in the control group (P < 0.05, P < 0.01).

CONCLUSIONSFI might believe the hemopoietic inhibition so as to promote the recovery of hemopoietic function through improving the T-lymphocyte subset and reducing the release of hemopoietic negative regulatory factors such as IFN-gamma, TNF-alpha and IL-2.
