ABSTRACT

Objective To understand the clinical characteristics and economic burden of influenza-like illness (ILI) children aged 0-59 months in the outpatient settings in Suzhou,China,2011-2017.Methods From March 2011 to February 2017,we conducted a prospective surveillance program on ILI for children aged less than 5 years at Soochow University Affiliated Children's Hospital.Through standard questionnaires and follow-up survey via telephone,we collected information regarding the demographic characteristics,medical history,clinical symptoms and both direct and indirect costs associated with influenza,of the patients.We then compared clinical characteristics and economic burden of influenza A/H1N1,A/H3N2,and B infections among children with ILI.Results We enrolled 6 310 patients with ILI from March 2011 to February 2017 and collected all their throat swabs.791 (12.9%) of the swabs showed positive for influenza virus,including 88 (11.1%) subtype influenza A/H1N1,288 (36.4%) subtype influenza A/H3N2,and 415 (52.5%) type influenza B.The proportions of cough,rhinorrhea,wheezing,vomiting and convulsion in influenza-positive children were higher than those influenza-negative children.Except for the prevalence rates of cough (x2=9.227,P=0.010),wheezing (x2=7.273,P=0.026) and vomiting (x2=8.163,P=0.017),other clinical symptoms appeared similar between the three viral subtypes.Among all the ILI children,the average total cost per episode of influenza was 688.4 Yuan (95% CI:630.1-746.7) for influenza-negative children;768.0 Yuan (95%CI:686.8-849.3) for influenza-positive children and 738.3 Yuan (95%CI:655.5-821.1) for influenza B.Children with influenza A/H1N1 spent much more than those with influenza A/H3N2 or influenza B in the total cost (x2=7.237,P=0.028).Conclusion Children infected influenza showed higher prevalence rates of cough,rhinorrhea,wheezing,vomiting and convulsion than those without influenza.Influenza A/H1N1 subtype caused heavier economic burden than the other two influenza subtypes.

ABSTRACT

Objective To evaluate the predictive role of TEL/AML1 fusion gene in protocol CCLG-ALL-2008 and to identify relevant factors influencing the outcome of ALL with TEL/AML1 fusion gene. Methods Ninety-nine patients with ALL harboring TEL/AML1 fusion gene (positive) and 329 cases without any specific fusion genes (negative) at diagnosis of B-lineage ALL from June 2008 to December 2014 were enrolled and their clinical and biological features were analyzed. Following-up ended in October 2015, the survival status was calculated by K-M curve and prognostic factors were analyzed by COX model. Results There were no differences between the two groups in age, white blood cell at the diagnostic stage, and treatment responses at 4 time points, namely, prednisone good response on day 8, M3 status of BM on D15, and the minimal residual disease (MRD) more than 1.0×10-3 on day 33 and 12th week. During the follow-up period, the relapse rate was lower in the positive group than that in the negative group (14/99 vs 69/329), the mortality rate of the negative group was twice of that in the positive group (55/329 vs 8/99). The five-year overall survival (OS) rate, relapse-free survival (RFS) rate and event-free survival (EFS) rate of the positive group were (86.1 ± 4.9)%, (80.7 ± 5.1)% and (78.9 ± 5.1)%, respectively, and (79 ±2.8)%, (72± 3.1)%, and (69.6+ 3.1)% for the negative group as well. COX regression analysis indicated that relapse and MRD level at the 12th week were independent prognostic factors on OS, RFS, and EFS (P<0.05) for the two groups. Conclusions TEL/AML1 fusion gene could be regarded as a relatively good indicator of risks in ALL children treated by CCLG-ALL-2008 protocol. ALL patients with TEL/AML1 are recommended to receive more intensive therapy including hematopoietic stem cell transplantation when the patients were high level of MRD on the 12th week after treatment.

ABSTRACT

Objective To explore the gene sequencing and prenatal diagnosis of Glanzmann thrombasthenia (GT). Methods The blood samples were drawn from one case of phenotype GT pediatric patient, patient’s parents, and one normal control. The amniotic lfuid and cord blood from the fetus of patient’s mother were collected. When the fetus was born 2 days, the blood was drawn. The coagulation routine test and platelet aggregation test were performed. The expression of platelet membrane glycoprotein (GP) IIb and GPIIIa were tested by lfow cytometry. Microsatellite technology is used to determine whether fetal cord blood is contaminated with maternal cells. The expressed region and the junctional zone between exon and introns of GPIIb and GPIIIa were ampliifed by PCR technology from blood sample of patient, patient’s parents, and fetus’s cord and 2 days after birth. The PCR products were then subjected to DNA sequencing. Results Adenosine diphosphate (ADP) cannot induce the platelet aggregation in the patient. The max rate of the platelet aggregation in the fetus’s cord blood was half of the normal. However, the max aggregation rate induced by ADP in the blood sample of parents and fetus 2 days after birth were equal to normal. The mean lfuorescence intensity (MnX) of platelet membrane GPIIb and GPIIIa in the patient were 10%and nearly zero of the normal control, respectively, while those in the parents, the fetus’s cord blood and 2 days after birth were more than 90%and 30%to 50%of the normal control. The cast-off cells in amniotic lfuid and the DNA in cord blood analysis by microsatellite technology conifrmed that the amniotic lfuid and cord blood not contaminated by maternal cells. Gene analysis showed the heterozygosis mutation in exon6 A3829→C and exon9 G42186→A of the patient’s GPIIIa led to the amino acid heterozygosis mutation in GPIIIaHis281→Tyr and Cys400→Pro. These two mutations came from the father and the mother separately. However, there was only one heterozygosis mutation in exon9 G42186→A in the cast-off cells in amniotic lfuid, the fetus’s cord and blood 2 days after birth. Conclusion This GT patient have double heterozygosis mutation. The fetus has heterozygosis mutation conifrmed after birth.

ABSTRACT

<p><b>OBJECTIVE</b>A first report of 3 patients who developed hypofibrinogenemia due to long-term administration of hemocoagulase.</p><p><b>METHODS</b>The clinical data of three patients with hypofibrinogenemia due to long-term administration of hemocoagulase were analyzed, and the related literature was reviewed.</p><p><b>RESULTS</b>Case 1, a two-year old girl, had liver traumatic rupture and then treated with massive transfusion and fibrinogen infusion in addition to intravenous recombinant factor VIIa (two times) and hemocoagulase (2 U/d). The liver wound bleeding was soon stopped. However, her plasma fibrinogen level decreased to 0.12 g/L after continuous administration of hemocoagulase for 18 days. Case 2, a three-year old boy, had liver traumatic rupture and was treated with surgical repair, and then received hemocoagulase (2 U/d). On the 8th day, a large amount of blood was found to exude from abdominal cavity drainage tube and indwelling venous catheter, and his fibrinogen dropped to 0.24 g/L. Case 3 was a 45 year-old man who underwent a total mandibular resection because of malignant tumor, and he was given hemocoagulase (4 U/d). A continuous blood oozing was noted from his operation incision, and his fibrinogen level decreased to 0.25 g/L. All the three patients'plasma fibrinogen levels and coagulation tests returned to normal ranges after discontinuation of hemocoagulase administration and supplement of fibrinogen, and the bleeding stopped in cases 2 and 3.</p><p><b>CONCLUSION</b>Long-term use of hemocoagulase could induce hypofibrinogenemia and severe bleeding.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical and biological characteristics of childhood acute myeloid leukemia(AML)with 8;21 translocation.</p><p><b>METHODS</b>A retrospective analysis including clinical information, cell morphology, chromosome, immunophenotype and molecular biology was performed on 41 cases of childhood t(8;21)AML. The control group included 19 cases of AML without t(8;21) translocation detected during the same period.</p><p><b>RESULTS</b>The 41 cases of t(8;21)AML accounted for 68.3% of 60 continuous childhood AML patients. Among them, classical t(8;21) translocation was seen in 29 cases; variant t(8;21) translocation, simple 8q-, near-tetraploidy characterized by the duplication of t(8;21) translocation each came into view in 2 cases; and cryptic t(8;21) translocation was seen in 6 cases. Thirty seven cases (80.4%) belonged to M2 subtype of AML. Most of them had the morphological changes such as the leukemia cells' indent nucleus with a light stain region of perinucleus, basophilic cytoplasm, differentiation with maturation, megaloblastoid changes and nuclear-cytoplasm imbalance; the high expression of CD13 antigen; and the AML1/ETO fusion transcript in 23 cases examined by reverse transcription-polymerase chain reaction (RT-PCR) assay, including 6 cases with normal karyotype. The difference in complete remission rate between t(8;21) positive patients group and t(8;21) negative patients group was not significant in statistics (82.4% vs 75%, P>0.05). However the difference in recurring rate of the leukemia was statistically significant (10.7% vs 41.7%, P<0.05).</p><p><b>CONCLUSION</b>t(8;21)AML is the most frequent type of childhood AML. It is predominantly associated with M2 subtype of AML and has unique morphological, immunological prognostic features .</p>
