As the techruque of molecular biology developed, the research of aplastic anemia turns to the cytogenetical level. Scientists focused on irwestigating the relationship between the mutation of gene or chromosome and the curative effect of aplastic anemia.The results show that abnormality of particular chrromosome or gene will cause different outcome . On the other hand, the first line therapy of aplastic anemia is still IST or HSCT according to the different situation.The antibody special for T cell is still in studying, and the effect shows well .Through the typing diagnosis consummated, the treating method developed, the survival rate of the patient with apLastic anemia will be advanced.

Objective To study the morphological changes in peripheral blood cells and bone marrow cells of the patients suffering from mustard gas poisoning and their relationship with the degree of poisoning. Method The peripheral blood cells and marrow cells were examined morphologically after mustard gas poisoning. Results The total WBC count was reduced progressively in 44 patients, among them 10 patients showed granulocytopenia or agranulocytosis. Severe injury to eosinophils was seen also in the early period, and the percentage and absolute value of lymphocytes were significantly lowered too. However, platelets were not significantly influenced. The red cell count and hemoglobin level were elevated because of hemoconcentration. Blood marrow cells showed marked morphological changes. WBC became swollen with appearance of poisonous granules and vacuoles in their cytoplasm. Deformed lymphocytes (LY) could be found in the marrow cells of all the patients, mainly in the form of immature lymphocytes. It was shown that mustard gas produced serious damage to the hematopoitic cells of the bone marrow in the early period. Conclusions The examination of pheripheral blood and bone marrow cells is an important measure to determine the degree of mustard gas poisoning. The decrease in the absolute value of lymophocyte count and the time of its recovery, and degree of inhibition of hematopoiesis are closely related to the degree of mustard gas poisoning.

Objective To analyze the unreasonable elements in prescriptions from outpatient department through the intervention of unreasonable prescriptions;To provide evidence for reasonable usage of medicine in outpatient department.Methods Prescriptions were examined by senior pharmacists. If they found any unreasonable elements, they would consult doctors, and record all the unreasonable elements in the prescriptions to avoid unreasonable prescriptions. A total of 663 unreasonable prescriptions from Jan. 2011 to May 2013 were analyzed.Results A total of 709 unreasonable elements were found in these prescriptions. The man elements were following three types:overdose of toxic decoction pieces (73.76%), incompatible prescriptions without signature (12.13%), wrong inputting of prescription and decoction (7.76%).Conclusion With early intervention in prescriptions, the quality of prescriptions and the safety and effectiveness of medication can be improved.

Objective To investigate the possible association of circulating components of GH-IGFs-IGFBPs system with the GHR-exon 3 genotype in idiopathic short stature (ISS) children. Methods Genomic DNA was extracted and isolat-ed from peripheral leukocytes in 108 ISS children. GHR-exon 3 polymorphism was analyzed with multiplex poly-merase chain reactions (PCR) assay. According to the results of genotype, ISS children were divided into GHRfl group and GHRd 3 group. The height and weight were recorded in two groups. The body mass index (BMI) and BMI standard deviation score (SDS) were measured. The serum levels of insulin-like growth factor (IGF)-1, IGF-binding protein (IGFBP)-3, IGF-1 SDS and IGFBP3 SDS were calculated. GH stimulation test was used to measure the serum GH peak value. Fifty-five ISS chil-dren were treated with recombine human GH [0.15 IU/(kg·d)] for three months to analyse the association of IGF-1 response of GH treatment and genotypes. Results There were 63 GHRfl and 45 GHRd3 in 108 ISS children. There were no signifi-cant differences in BMI, IGF-1, IGFBP3, GH peak, IGF-1 SDS and IGFBP3 SDS between two groups (P>0.05). Multiple stepwise regression analysis showed that age, IGFBP3, lg (BMI) and lg (GH peak) were influencing factors of lgIGF-1 (P<0.05). In 55 ISS children treated with rhGH, there were 34 cases of GHRd3. The differences of △IGF-1 and △IGF-1 SDS were higher in GHRd3 group than those of GHRfl group (n=21). Conclusion The GH sensitivity may be a risk factor in ISS children, which may not be related with GHR polymorphism.

Objective To investigate the changes in the number of microglias and astrocytes in the spinal dorsal born in a rat model of phantom limb pain.Methods Eleven healthy adult SD rats of both sexes weighing 290-300 g were randomly divided into 2 groups:sham operation group (group S,n =5 ) and unilateral sciatic nerve transection group (group SNT,n =6).Phantom limb pain model was induced by resection of a 0.5 cm segment of unilateral sciatic nerve in group SNT.In group S unilateral sciatic nerve was exposed but not transected.The animals were observed for autotomy and scored (0 =no autotomy,13 =the worst autotomy) after operation and were sacrificed on the 28th day after operation.The L5 segment of the spinal cord was removed for determination of the number of microglials (by iba-1 immuno-histochemistry) and astrocytes (by GFAP immuno-histochemistry).Results In group S no animal developed autotomy.In group SNT autotomy started from the 2nd day after operation and the score reached 9-11.Compared with group S,the number of the microglias and astrocytes in the spinal dorsal horn was significantly decreased in the operated side in group SNT ( P ＜ 0.05 ).Conclusion The number of microglias and astrocytes in the spinal dorsal horn is decreased in animals with phantom limb pain.

Objective To investigate the clinical manifestations of the febrile neutropenia cancer children,explore the relationship between the clinical data and sepsis.Methods A prospective observation study was employed,and 66 cancer children complicated with febrile and neutropenia after chemotherapy were enrolled.Sixty-six cases were divided into two groups:septic group ( n =26 ) and non-septic group ( n =40).Clinical and laboratory data were collected and compared.Results Body temperature,neutropenia duration,absolute neutrophic count ( ANC ),C-reactive protein ( CRP ),procalcitonin (PCT) and culture positive rate showed statistically differences between the septic and non-septic groups ( P ＜ 0.05 ).Body temperature ＞40 ℃,ANC ＜ 0.1 × 109/L,increases of serum CRP and PCT levels and positive culture were correlated with sepsis.Body temperature ＜ 39 ℃,neutropenia duration ＜ 5 ds,ANC ＞ 0.5 × 109/L were less correlated with sepsis.Conclusion High initial temperature,long duration of neutropenia,severely reduced ANC,increases of CRP and PCT,and culture-positive are correlated with sepsis in cancer children.

Objective To investigate the changes in the number of synapses and neurons in the spinal dorsal horn in a rat model of phantom limb pain. Methods Eleven healthy adult SD rats of both sexes weighing 209-300 g were randomly divided into 2 groups: sham operation group (group S, n = 5) and phantom limb pain group (group P, n = 6). Phantom limb pain was induced by resection of a 0.5 cm segment of unilateral sciatic nerve in group P. In group S unilateral sciatic nerve was exposed but not transected. The animals were observed for autotomy and scored (0 = no autotomy, 13 = the worst autotomy) after operation and were sacrificed on the 28th day after operation. The L3-6 segment of the spinal cord was removed for determination of the number of neurons (by Nissl's staining) and synapses (by synaptophysin immuno-histochemistry).Results In group S no animal developed autotomy. In group P autotomy started from the 2nd day after operation and the score reached 9-11. The number of the neurons in the spinal dorsal horn in all 4 segments and the number of synapses in L3 and 16 segments were comparable between the two sides and the 2 groups. The number of synapses in the spinal dorsal horn of L4and L5 segment was significantly larger in the operated side than in the contralateral side in group P. Conclusion The number of synapses in the spinal dorsal horn significantly increases in animals with plantom limb pain which induces no increase in the number of neurons in the spinal dorsal horn.
