Objective:To compare the nutritional evaluation methods and to analyze the clinical value of different nutritional evaluation indexes in acute lymphoblastic leukemia (ALL) pediatric patients during the stage of remission induction.Methods:The clinical data of 132 ALL pediatric patients who were diagnosed and treated with remission induction in Shanghai Children′s Medical Center, School of Medicine, Shanghai Jiao Tong University from January 2018 to December 2020 were collected by convenient sampling method. The body composition was measured by direct segmental multifrequency bioelectrical impedance measurement (DSM-BIA), and the height, weight, upper arm circumference and triceps skinfold thickness were also measured. The Screening Tool for the Assessment of Malnutrition in Pediatrics scores were calculated. The serum albumin value and the hemoglobin value were monitored. Using DSM-BIA as the reference standard, the accuracy of different nutritional evaluation indexes was investigated and analyzed.Results:During the stage of remission induction in ALL pediatric patients, there were 69 out of 132 children who had the muscle mass below normal. The muscle mass below normal was detected in 52.3% (69/132). And the upper arm circumference had the highest correlation and the minimal standard error with muscle mass measured by DSM-BIA ( R2=0.520, SE=0.180). Grouped with nutritional status by the upper arm circumference, the children with normal nutritional status had lower incidence of very severe neutropenia 76.8% (24/32) than 92.1% (70/76) with abnormal nutritional status ( χ2=6.14, P=0.013). Conclusions:During the stage of remission induction in ALL pediatric patients, the malnutrition rate is high. The upper arm circumference is a simple index which can accurately reflect the nutritional status of the ALL pediatric patients. It is suggested that the upper arm circumference should be used as the primary screening index of clinical nutrition by clinical nurses.

Objective@#To investigate the efficacy of alternative donor (AD) in the treatment of aplastic anemia (AA) in children.@*Methods@#The clinical data of AA children who received AD HSCT in our center from Apr. 2010 to Dec. 2016 were retrospectively analyzed. The overall survival (OS) rate, implant success rate, incidence of acute and chronic graft-versus-host disease (GVHD) were statistically analyzed.@*Results@#A total of 109 children with acquired AA, including 64 severe AA (SAA) , 32 very severe AA (VSAA) and 13 transfusion dependent non-severe AA (NSAA) , were recruited in this retrospective AD HSCT study, the median age was 6 (0.8-18) years old. Of them, 44 patients with 10/10 matched unrelated donor (MUD) , 44 patients with mismatched unrelated donor (MMUD) and 21 patients with mismatched related donor (MMRD) . All patients did not receive ATG before HSCT and the active infection was excluded. Except 3 patients suffered from a second graft failure (2 of them rescued by second HSCT) , 106/109 (97.2%) were engrafted with neutrophil and platelet recovery occurring at a median of 13 days (range, 9-19) and 16 days (range, 10-81) post-transplant. Until day 100 post transplantation, the incidence was 74.3% (81/109) for acute GVHD (aGVHD) and 39.4% (43/109) for grade Ⅱ-Ⅳ aGVHD, 30.7% (31/101) and 9.9% (10/101) for overall chronic GVHD (cGVHD) and moderate cGVHD, respectively, and nobody developed an extend cGVHD. After median follow up of 39 (0.7-103) months for all patients, 13 of 109 patients died. The estimated 5-year overall survival (OS) of the entire cohort was 88.1% (95%CI 81.1%-91.4%) with no difference among the MUD, MMUD and MMRD cohort (93.2%, 84.1% and 85.7%, respectively, P=0.361) .@*Conclusion@#These excellent outcomes suggest that unmanipulated AD PBSC is a good HSCT source for children with SAA. It’s reasonable to consider AD HSCT as first line therapy for SAA children without matched sibling donor. Better strategies are required to prevent GVHD.

Objective To observe the morphological changes of rats' pancreas and nitric oxide (NO) and endothelin(ET) in the blood serum in rats after exposure to different pulses of high power pulse microwave (HPPMW).Methods SD-rats were irradiated with 104,105 and 4 × 105 pulses of HPPMW,respectively.After gloss observation,the histopathological changes of pancreas were observed through biological microscope and electroscope.The changes of amylase,nitric oxide and endothelin in blood serum were detected by biochemical and radio-immunological methods. Results Compared with the blank control,no apparent abnormality could be observed in the pancreas of all groups.The dilatation of capillary could be observed in each experimental group by microscope.The ultrastructure changes of pancreas were most serious in 4 × 105 pulse group,especially at 24 and 48 h after irradiation.Compared with the control group,the levels of serum amylase were decreased (F =12.58,11.73,P < 0.05),while ET were increased (F =4.50,4.49,P <0.05) at 24 and 48 h after irradiation.The levels of NO in serum were increased ( F =17.51,41.72,19.98,32.64,P < 0.05 ) at each time-point.The level of NO went up with the increase of pulses.Conclusions HPPMW has damage effects on the pancreas in rats.The pulses with the pancreas can lead to severity of the damage. The mechanism of HPPMW may be involved in the enhancement of ET and NO in serum.

Objective To investigate the effects of Astragalus Polysaccharide (for intravenous injection) in stimulating the secretion of hematopoietic growth factors from activated human peripheral blood mononuclear cells (PBMC). Methods Human PBMC were isolated from concentrated leukocytes and were cultured with Astragalus Polysaccharide. Hematopoietic growth factors such as granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in the supernatant were determined by enzyme-linked immunosorbent assay (ELISA). Results Astragalus Polysaccharide stimulated G-CSF and GM-CSF formation in a dose-dependent and a dose-effect and time-dependent manner. Conclusion Astragalus Polysaccharide can stimulate the secretion of hematopoietic growth factors from activated human PBMC, indicating its clinical application for leukocytopoiesis.
