Promyelocytic leukemia (PML) protein can regulate many cellular processes, Here we summarize the role of PML protein in cell and mechanisms according to researches in recent years.

Hematopoietic stem cell transplantation(HSCT) is one of the measures therapy on acute leukemia in children.Very-high-risk children with acute lymphocytic leukemia (ALL),such as Philadelphia chromosome-positive(Ph+),T cell immunophenotype,achieved the first complete remission(CR1),and then receive allogeneic HSCT(allo-HSCT).The transplantation group had significantly improved disease-free survival(DFS)and overall survival(OS) compared with chemotherapy group. ALL children in the second complete remission(CR2) were recommended to receive allo-HSCT,especially early-relapse group. All children in the third complete remission (CR3) were recommended to receive an allo-HSCT,and reduce replapse rate through inducing graft versus leukemia.Total body irradiation-based conditioning regimens in children with ALL has advantage over chemotherapy conditioning regimens.Children with acute myeloblastic leukemia (AML) achieved CR1 and then undergo all-HSCT.This group had significantly improved DFS and OS compared with chemotherapy group.The children with relapsed AML,if having suitable donor,were recommended to receive allo-HSCT. The children with AML who underwent transplantation relapse,and can receive the second transplantation.There was no advantage in children patients with AML using TBI-based conditioning regimens.Conditioning regimens consisted of high-dose cytarabine,in combination with granulocyte colony-stimulating factor has advantage,and improve DFS. Unrelated umbilical cord blood has emerged as a potential option.Compared with unrelated bone marrow transplantation,there was no different in DFS and relapse.For the extent,it is one of the donor hematopoietic stem cell sources.

Objective To discuss the mechanism of rubia cordifolia extractive affecting some biochemical indicators of blood serum and sporting ability in highly endurance-trained rats,which can provide theoretical basis for using rubia cordifolia extractive as sport supplements.Methods After establishing the highly endurance-trained rats model,we tested the exhaustion time in the trained rats and the contents of serum urea(BUN),lactic dehydrogenase(LOH),blood lactate(BLa)as well as the cruarin(Hb)in the rats.Results The activity of LDH in training group was greater than that in silent group(P

Objective To demonstrate the manifestations on positron emission tomographycomputed tomography (PET-CT) at different stages in anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis.Methods PET-CT was performed in 10 patients with anti-NMDAR encephalitis at different clinical stages,and the images were analyzed to investigate the relation of metabolic patterns in the images with clinical presentations.Results Except for normal PET-CT images in 2 patients,images in 8 patients at early stage of the disease showed generally increased 2-[18F] fluoro-2-Deoxy-D-glucose(18F-FDG) uptake at frontal and temporal lobe,basal ganglion and cerebellum,indicating hyper-metabolism in these areas,while 2 of them also had mixture of hyper-and hypo-metabolism in parietal-occipital region.In longitudinal analysis of PET-CT images in these 8 cases,starting at basal ganglion,18 F-FDG uptake gradually decreased bilaterally,prominently at left dominant hemisphere and right cerebellum.Conclusions During the course of anti-NMDAR encephalitis,18F-FDG metabolism markedly increases at early stage and then gradually declines at late stage,at frontal,temporal,parietal and occipital lobes,basal ganglion and cerebellum,predominantly at left dominant hemisphere and right cerebellum.However,in relapsing anti-NMDAR encephalitis,18 F-FDG metabolism in brain does not show these characteristics.

Objective To investigate differences between Han and Uyghur children in dyslexia prevalence and potential environmental risk factors as well as to provide diagnosis and treatment evidence for dyslexia children . Methods We used cluster sampling to recruit 2 854 students in grades 3~6 from five Uyghur -Chinese bilingual primary schools in Xinjiang province .The children with dyslexia were selected step by step according to the defini‐tion of ICD-10 and DSM -IV .The children with DD and children without DD were selected and compared by 1∶1 of the same class ,ages and genders .Then single factor analysis and logistic regression analysis were used to as‐sess children'environmental risk factors .Results In total ,2 438 effective quostionnaires have been got .The difference between Han (3 .89% ) and Uyghur (7 .05% ) dyslexia prevalence was statistically significant .The factor analysis revealed that educational grades ,family income ,father's and mother's occupations ,and their education levels as well as some home literacy environmental factors were significantly different for the two groups of children with dyslexia (P<0 .05) .Conclusion The prevalence of dyslexia was high in both groups ,and especially for Uyghur children . Some environmental factors may be responsible for the differences noted ,especially for the occupation of mother .

Objective To compare the differences of blood glucose detected by four methods with different instruments and specimen types at early stage in severely burned rats.Methods 24 Sprague-Dawley (SD) rats were randomly divided into two groups:control group 1 (Sham scald group,n=8) and scald injury group 1 (n=16).Blood samples of scald injury group 1 were collected at 12,and 24 hours after scald (n=8,each time).Another 20 SD rats were randomly divided into two groups:control group 2 (Sham scald group,n=10) and scald injury group 2 (n=10).Blood samples of scald injury group 2 were collected at 12 hours after scald.The rats in scald injury group 1 and 2 were placed into scalding water (95.0±0.5)℃ for 15 seconds to model third-degree burn with 30％ total burn surface area (TBSA).The rats in scald injury group 1 were given intraperitoneal injection with normal saline(40 ml/kg) immediately,while those in scald injury group 2 were given intraperitoneal injection with normal saline (40 ml/kg) 6 hours after scald.The rats in Sham scald group 1 and 2 were placed into warm water 37℃ for 15 seconds,and did not received injection.Portable glucometer/caudal artery (vein) blood,portable glucometer/abdominal aorta blood,spectrophotometer/femoral venous plasma,and spectrophotometer/abdominal aorta plasma were used to detect blood glucose.Results ①Compared with Sham scald group 1,the levels of blood glucose detected by portable glucometer/caudal artery (vein) blood and spectrophotometer/femoral venous plasma in scald injury group1 at 12,24 hours after scald were significantly increased(P＜0.05).Compared with Sham scald group 2,the levels of blood glucose detected by portable glucometer/abdominal aorta blood and spectrophotometer/abdominal aorta plasma in scald injury group 2 at 12 hours after scald were significantly increased(P＜0.05).②The comparison of portable glucometer/caudal artery (vein) blood and spectrophotometer/femoral venous plasma in Sham scald group 1,portable glucometer/abdominal aorta blood and spectrophotometer/abdominal aorta plasma in Sham scald group 2 had no statistical significance (P＞0.05).The levels of blood glucose detected by portable glucometer/caudal artery (vein) blood were significantly lower than those detected by spectrophotometer/femoral venous plasma (P＜0.05) in scald injury group 1.The comparison of blood glucose detected by portable glucometer/abdominal aorta blood and spectrophotometer/abdominal aorta plasma had no statistical significance in scald injury group 2 (P＞0.05).Conclusion Four kinds of methods used in this study shows that the levels of blood glucose were significantly increased at early stage in severely burned rats,and the portable glucometer/abdominal aorta blood is a relatively simple and fast method to detect blood glucose.
