Gaucher disease is a lysosomal storage disease for which enzyme replacement therapy has proven to be effective. A switch-over clinical trial was performed to evaluate the efficacy and safety of Abcertin(R) (ISU Abxis, Seoul, Korea) in subjects with type 1 Gaucher disease who were previously treated with imiglucerase. Five Korean patients with type 1 Gaucher disease were enrolled. Previous doses of imiglucerase ranged from 30 to 55 U/kg every other week. The same dose of Abcertin(R) was administered to all patients for 24 weeks. Primary efficacy endpoints were changes in hemoglobin levels and platelet counts, and the secondary efficacy endpoints included changes in liver and spleen volumes, serum biomarkers, skeletal status and bone mineral density (BMD). During the study period, no statistically significant changes were observed in all parameters including hemoglobin levels and platelet counts, liver and spleen volumes, skeletal status and BMD. Abcertin(R) administration was continued in three patients for another 24 weeks as an extension of the study. Hemoglobin levels and platelet counts were maintained in all three patients. In conclusion, the efficacy and safety of Abcertin(R) are similar to those of imiglucerase, and Abcertin(R) is an effective therapeutic agent for patients with type 1 Gaucher disease (Clinical Trial Registry No. NCT02053896 at www.clinicaltrials.gov).

Tn order to set up a mouse model of myelofibrosis (MF) induced with high dose recombinant human erythropoietin (rhEPO). 60 mice were collected and divided into EPO and control groups, the former was injected with rhEPO and the latter with normal saline intraperitoneally. 5 mice from each group were executed on day 6, 30, 60, 90, 120 and 150 respectively. Their WBC count, Hb level, MCV, RDW and platelet amount were measured by automatic blood cell analyzer; CD34(+) cell ratio in bone marrow were analyzed by flow cytometry; liver and spleen coefficients were measured; pathological changes of liver, spleen, femur were observed by HE staining and reticular fibers staining; cortex thickness, femoral canal diameter and lumbar spine density were determined by computerized tomography (CT). The results indicated that as compared with normal control group in EPO induced group, WBC count was increased slightly in whole period, but without statistic significance (p > 0.05), Hb level and RDW increased at day 6 and 30 significantly (p < 0.05), MCV increased at day 6 significantly (p < 0.05), but platelet amount decreased significantly at all time points (p < 0.05). Most mice in EPO-induced group had hepatomegalia and their liver and spleen coefficient increased significantly at day 60 (p < 0.05), while most mice had splenomegaly and its coefficient was increased significantly at all time-points (p < 0.05). CD43(+) cell ratio of EPO group increased significantly in whole period (p < 0.05). CT scanning displayed femoral cortical thickening, medulla canal narrowing and lumbar spine density increasing at day 150, meanwhile, HE staining and reticular fiber staining showed the fatty degeneration or vacuolization in liver, splenomegaly with megakaryocytic proliferation, femur bone marrow fibrosis and osteosclerosis. It is concluded that the mouse induced by high dose of rhEPO displays the myelofibrosis associated with splenic extramedullary hemopoiesis, and this study is useful to establish a practical MF model, and to explore its pathological mechanism.

6.Clinical analysis of curative effect of rhG-CSF on chemotherapy-induced leukopenia in cancer patients.
Journal of Experimental Hematology 2003;11(2):205-207
Myelosupression is the major dose-limiting toxicity in most chemotherapeutic drugs. To evaluate the curative effect of a domestic product of rhG-CSF on chemotherapy-induced leukopenia, 132 patients with malignancies were enrolled, including 80 patients with lung cancer, 35 patients with breast cancer, 10 patients with nasopharyngeal carcinoma, 3 patients with non-Hodgkin's lymphoma, 2 patients with gastric carcinoma and 2 patients with bone metastasis. Total of 528 cycles of chemotherapy were performed. The results showed that according the grade of leukopenia, the different daily doses of the domestic product of rhG-CSF were administered: 75 micro g/d for 3 days, 150 micro g/d for 4 days and 300 micro g/d for 5 days, in grade I-II, grade III and grade IV groups, respectively, the times of recovery to normal level of white blood cells were 2.5, 4.2 and 7 days in 3 groups, respectively. In conclusion, The Chinese product of rhG-CSF shortened the duration of leukopenia and accelerated the hematologic recovery, which shows only slight side effects, so that patients receive the optimal doses of chemotherapy and completed the planned schedule on time.

7.Curative effect of rhG-CSF on leukopenia induced by chemoradiotherapy in 140 cases of malignant tumors.
Journal of Experimental Hematology 2004;12(1):103-104
This study was to evaluate the effect of a Chinese genetic engineering product of rhG-CSF (Lishengsu) on leukopenia induced by chemoradiotherapy in patients with malignant solid tumors. One hundred and forty cases of leukopenia following chemoradiotherapy for malignant tumors were treated with Lishengsu. When the total leukocyte counts (WBC) less than 3.0 x 10(9)/L or the absolute neutrophil count (ANC) less than 2.0 x 10(9)/L, Lishengsu was given 75 micro g/day subantaneously and the administration was stopped when the WBC counts rose up to 4.0 x 10(9)/L or higher, or the ANC counts reached 2.5 x 10(9)/L or more. The results showed that peripheral leukocyte counts in all patients following the treatment with Lishengsu were recovered and the average time of its administration was 4.8 days. The rate of its efficaciousness was 96.4%. It is concluded that Lishengsu could elevate nadirs of leukopenia and significantly shortened time period of leukopenia below 4.0 x 10(9)/L with acceptable mild side effects, decrease complications of infection so that the chinese product of rhG-CSF facilitates chemoradiotherapy significantly.

8.Safety of recombinant human growth hormone in treating children with growth hormone deficiency and idiopathic short stature.
Acta Academiae Medicinae Sinicae 2011;33(2):123-126
Recombinant human growth hormone is generally safe in treating children with growth hormone deficiency and idiopathic short stature. However, side effects such as sodium and water retention, benign intracranial hypertension, insulin insensitivity, increasing risk of secondary neoplasm, scoliosis, and slipped capital femoral epiphysis may occur occasionally, although the overall incidence remains low.

This study was purposed to evaluate the effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on hematopoietic reconstruction and survival in beagles exposed to mixed fission neutron and γ-ray. 13 beagles were unilaterally exposed to single dose of 2.3 Gy 90% neutrons. The experiments were divided into 3 groups: irradiation control group (no any treatment, n = 4), supportive care group (n = 5) and rhG-CSF plus supportive care group (n = 4, abbreviated as rhG-CSF group) in which the beagles were subcutaneously injected with 200 µg/kg of rhG-CSF early at half an hour and 24 hours post-irradiation respectively. The results showed that 2.3 Gy 90% neutron irradiation induced a severe acute radiation sickness of bone marrow type. The administration of rhG-CSF increased the survival rate from 60% in supportive care group to 100%. Twice injection of rhG-CSF in the first 24 hours reduced duration of neutropenia, enhanced neutrophil nadir and promoted neutrophil recovery when compared with control cohort administered clinical support. The number of colony-forming cells (CFU-GM, CFU-E, and BFU-E) in peripheral blood of rhG-CSF treated canines increased 2-to 5-fold relative to those of the supportive care group on day 3. All canines treated with rhG-CSF achieved hematopoietic reconstruction as evidenced by the pathological section of sternum while severe shortage of hemopoietic cells remained in the cohorts given supportive care alone. It is concluded that the combination of supportive care and high-dose rhG-CSF can accelerate hematopoietic recovery and enhance survival of dogs exposed to 2.3 Gy mixed neutron and gamma ray.
