Objective To explore the immunophenotype of children with acute myeloid leukemia(AML) and its clinical significance.Methods Statistics was used to analyze the relationship between the immunophenotype of AML and their French-American-Britain(FAB) classification,complete remission (CR) in one month and 3-years event-free survival(EFS).Results CR rate was 71.6% and 3-years EFS rate was 50.8%. HLA-DR and CD34 absent mainly in M3, associated with higher CR and EFS rate. So did CD33 negative cases, especially in M2. CD13 positive was significantly predictive factor for achieving CR.Co-expression of lymphoid antigens and NK cell antigens(CD56) with M2 which correlated with lower CR and EFS rate.Conclusions The negative of HLA-DR, CD34, CD33,as well as CD13 positive, have relationship with good prognosis. Lymphoid antigens and CD56 are poor prognostic factors.

Objective To observe the clinical effects of different doses of botulinum toxin A (BTX-A) and different lacation ways on children with spastic cerebral palsy. Methods One hundred and twenty patients with BTX-A were employed in our study;these patients were performed locations of electromyography (n=60) and reverse stretching hand (n=60), and then, they were equally sub-divided into 6 groups, respectively: receiving injection of BTX-A at doses of 3, 4 and 5 U/kg, respectively (n=20).After injection, they were commenced functional training for 3 months. The gross motor assessment scale (GMFM) was used to assess the motor function of functional areas in these children 3 months after the training. The modified Ashworth scale was used to assess the degree of muscle spasticity. Results The scores of GMFM in patients received treatment with location of electromyography increased as compared with those with reverse stretching hand (P< 0.05), but the scores had no statistically significances among different doses of BTX-A treatment groups (P> 0.05). The Ashwort grade in patients received treatment with location of electromyography alleviated as compared with those with reverse stretching hand (P<0.05), but no statistically significance of grading was noted among different doses of BTX-A treatment groups (P>0.05). Conclusion All parameters in patients received treatment with location of electromyography improve better than those with reverse stretching hand after injection of same dose of BTX-A.

In order to establish a new more rapid, safe and sensitive colorimetric assay for the proliferation of leukemic cells, MTS/pms has been developed. This automated colorimetric assay is based on the characteristic of viable and metabolically active leukemic cells to cleave MTS/pms into a water-soluble product whose optical density is determined at 492 nm by an automated microtiter-plate reader photometer. The results indicated that only active leukemic cells cleaved MTS/pms into product measured, and dead cells did not reduce MTS/pms. A linear relations hip were found between the viable cell number and optical density of MTS/pms cleaved by HL-60 and K562 cell (r = 0.963). Compared with MTT and INT assays, the reduced product of MTS/pms is water-soluble. It is concluded that MTS/pms colorimetric assay is more rapid, accurate and sensitive for the bioassay of proliferation of leukemic cells.

OBJECTIVETo retrospectively analyze the treatment outcomes and side effects of childhood acute promyelocytic leukemia (APL) treated with all-trans retinoic acid (ATRA) or ATRA + arsenic trioxide (As2O3).

METHODSFrom 1992 to 2006, 45 patients with newly diagnosed APL were enrolled. All of them were PML-RAR alpha positive. 24 patients were induced with ATRA (group A) and 21 with ATRA + As2O3 (group B). The remission rate and side effects were observed.

RESULTS1) 19 (79.2%) patients in group A achieved CR, while 21(100%) patients in group B achieved CR. The CR rate in group A was lower than that in group B (P=0.027). 2) The recovery time of coagulation parameters and PLT count in group B was shorter than that in group A. 3) The overall survival (OS) and event-free survival(EFS) in group A were 77.8% and 66.9% at 41 months of follow-up, and in group B were 100% and 100% respectively at 34 months of followup. Group A had a significant lower EFS (P=0.0357)than group B. 4) The time of PML-RAR alpha fusion gene converting to negative in group A was longer (P=0.026) than that in group B.

CONCLUSIONSATRA + As2O3 for patients with newly diagnosed childhood APL is a feasible treatment with higher CR rate, less side effects and longer long-term survival.

OBJECTIVETo explore the association of the glycophorin A(GPA) gene mutation in peripheral erythrocytes and chronic benzene poisoning.

METHODSSixty-three patients with chronic benzene poisonings and 45 benzene-exposed workers who were engaged in the same job title were investigated. Fluorescence immunolabeling technique and flow cytometry were used to detect GPA mutation frequency in peripheral read blood cell.

RESULTSA significant decrease in WBC count and neutrophil count was found in patients with chronic benzene poisoning compared with control individuals (P<0.01). The WBC count and neutrophil count both decreased along with the GPA-NN frequency, and the trends were significant(P<0.05).Both WBC counts and neutrophil counts decreased as the frequency, and trends were significant(P<0.05). GPA-NN frequency increased along with the accumulative exposure score, and the trend was significant (P = 0.0026). There was no significant trend between the GPA-Nphi frequency and the accumulative exposure score (P = 0.2037).

CONCLUSIONA decrease in WBC count and neutrophil count is found in patients with chronic benzene poisoning, which can arise from genetic damage in bone marrow stem cells, namely gene-duplicating mutations (NN) at the GPA locus in bone marrow cells of MN-heterozygous subjects, GPA-NN mutagens contributed to the pathogenesis of chronic benzene poisoning.

Abstract?AIM:To investigate the effective treatment methods of corneal injury caused by chestnut thorns and the factors affecting the disease progression.?METHODS: From Jul.2014 to Oct.2015, the clinical data of 15 patients(15 eyes) with corneal injury caused by chestnut thorns in Ophthalmology Inpatient Department of Wuhan Tongji Hospital was retrospective analyzed. The patients without fungal keratitis were treated with the surgery of removing chestnut thorn from cornea and antifungal drugs. For the patients complicated with fungal keratitis, besides surgery of removing chestnut thorn and antifungal drugs, anterior chamber irrigation and corneal stroma injection with fluconazole solution were given to treat the disease.If necessary, amniotic membrane transplantation or keratoplasty was also given to the patients complicated with fungal keratitis. After that, the effectiveness of those methods and the factors affecting progression were analyzed.?RESULTS:For 11 patients without fungal keratitis, the average time between corneal injury and receiving treatment at Tongji Hospital was 1-7 (2.42±2.15) d and for 4 patients complicated with fungal keratitis, the average time was 3-30 (18.25±4.35)d.Among 15 cases, statistics suggested that the average number of chestnut thorn in patients complicated with fungal keratitis was 4.5, and all the chestnut thorn penetrated the cornea into the anterior chamber.The average number of chestnut thorn in patients without fungal keratitis was 3.5, and the proportion of chestnut thorn penetrated the cornea into the anterior chamber was 28.5%.After treatment, all patients had no new fungal keratitis or other complications.Those results indicated that the different treatments for the patients with or without fungal keratitis were all effective.?CONCLUSION:The factors affecting the progression of cornea foreign body injury caused by chestnut thorn are the number of chestnut thorn, whether chestnut thorn penetrate the cornea into the anterior chamber, time since injury, active anti -fungal therapy. If patients complicated with fungal keratitis could be treated with antifungal agents and anterior chamber irrigation or corneal stroma injection using fluconazole solution without delay, the progress of fungal keratitis could be effectively controlled, and favorable conditions for further therapy such as amniotic membrane transplantation or keratoplasty could be provided.

Objective To analyze the clinical value of minimal residual disease(MRD) of acute myeloblastic leukemia(AML) with AML 1-ETO by using the real-time quantitative reverse transcriptase polymerase chain reaction(RQ-RT-PCR).Methods From Jan.2001 to Jan.2007,the MRD of 32 AML1-ETO-positive AML patients were analyzed by using PQ-RT-PCR.The detection of the AML1-ETO was taken after the induced chemotherapy every 1.5-2.0 months during the consolidation therapy.The survival of different stages in children with AML was analyzed by SPSS 10.0 software and calculated by using Kaplan-Meier analysis.Results Thirty-two patients received the induced chemotherapy and 29 patients with complete remission morphologically,3 patients had no complete remission morphologically and then gave up.Patients with molecular remission were associated with a high probability of survival(P=0.001 8).Patients with high transcript levels at diagnosis had no difference in event free survival with patients with low transcript levels.The quality of molecular response after induction,6 months in the chemotherapy as well as consolidation period,has significant impact on the event free survival(P=0.023,0.000 1,0.004 9).Conclusion The current study demonstrate that quantitative evaluation of AML1-ETO transcript levels is important and may be helpful for therapeutic decisions in future.
