1.Assays of the minimal residual disease in pediatric acute leukemia
International Journal of Pediatrics 2011;38(3):229-231
Minimal residual disease(MRD)iS the origin of relapse in leukemia.So it's significant to quantitate MRD in clinical.At present, there are three MRD quantitative assays, such as flow cytometric detection of abnormal immuno-phenotype,polymerase chain reaction(PCR)amplification of antigenreceptor genes and fusion transcripts.Because every measure has its own principle and feature.the clinical applications are different.Selecting suitable assays based on the characteristic of patients can help to quantitate MRD exactly.

3.Advances of the relationship of asthma and store-operated calcium
International Journal of Pediatrics 2013;(3):234-236
As one of the chronic diseases,asthma,plays a serious impact on human daily life.Asthma in children has showed an increasing trend in recent years,but the mechanisms of asthma are not yet clear.Studies have found that store-operated calcium entry(SOCE) plays an important role in the physiological activity of the body.The enhanced SOCE activity can promote cell growth,proliferation,and migration of a variety of cell types.SOCE important molecules STIM1 and ORAI1 may be involved in the asthmatic airway occurrence of hyperresponsiveness and airway remodeling,and closely to the asthmatic development.
4.Progress or screening and prognosis evaluation of cytomegalovirus infection in perinatal period
International Journal of Pediatrics 2012;39(3):237-241
Cytomegalovirus (CMV),a DNA herpusvirusesw,is the most common virus leading to intrauterine infetcion.It is transmitted from mother to fetus through placenta,and the neonates who suffering from congenital symptomatic infections may have sensorineural hearing loss,hepatosplenomegaly,microcephaly,chorioretinitis etc.Studies have suggested that the characters of infections on pregnant women,such as the time of infection,the serological results and virus load in amniotic fluid are associated with the outcome of offsprings.This paper is to review the risk of CMV infections on women at childbearing age,screening of CMV infections on pregnant women and the prenatal diagonosis of fetal CMV infection.
5.Fasting blood glucose and prognosis of patients surviving over 1 year after renal transplantation
Chinese Journal of Tissue Engineering Research 2015;(24):3924-3928
BACKGROUND:Diabetes mel itus after kidney transplantation is an important metabolic complication of the transplanted organ, and seriously affects the quality of life and long-term survival rate of patients, which is a risk factor for renal al ograft dysfunction and cardiovascular disease. OBJECTIVE:To investigate the changes in fasting blood glucose and prognosis of patients who had survived more than 1 year after renal transplantation. METHODS:Total y 42 patients undergoing renal transplantation admitted at Xiantao First People’s Hospital from January 2003 to January 2013, including 7 cases of preoperative diabetes, 11 cases of impaired fasting glucose and 24 cases of normal fasting blood glucose. Fasting blood glucose levels were detected at 1, 7, 14 days and 1, 3, 6, 12 months after renal transplantation, and the survival conditions were also compared among different groups. Cox proportional hazard model was used to analyze influential factors of survival in patients undergoing renal transplantation. RESULTS AND CONCLUSION:The fasting blood glucose levels in the diabetes mel itus group were significantly higher than those in the impaired fasting glucose group and normal fasting blood glucose group before and after renal transplantation (P<0.05). The fasting blood glucose levels were increased in al the groups at 1 day after transplantation (P<0.05), and stabilized at 3 months after transplantation. The survival rate was significantly higher in the normal fasting blood glucose group than in the diabetes mel itus and impaired fasting glucose groups after renal transplantation (P<0.05). Cox proportional hazard model analysis showed that preoperative fasting blood glucose, age, postoperative tumor and infection were the independent risk factors for death in patients undergoing renal transplantation, among which, postoperative tumor led to the highest death risk ratio that was 2.376. Taken together, preoperative diabetes mel itus has some impacts on renal recipients who survive more than 1 year fol owing transplantation, but postoperative diabetes mel itus had no influence on the survival rate of the patients.

8.Gene type study of alpha-thalassaemia in Chongqing
Journal of Chongqing Medical University 2007;0(08):-
Objectives:To study the distribution status,clinical manifestations and laboratory test characteristics of alpha-thalassaemia gene type in the city of ChongQing to approach the importance of genetic diagnosis for alpha-thalassaemia,and the significance of thia diagnosis for antenatal screening and prenatal diagnosis to promote the survival quality of human being.Methods:This study was performed in the Children's Hospital of Chongqing Medical University.One hundred and three alpha -thalassaemia patients were involved in this study.They had taken the tests of serum iron(SI),total iron binding capacity(TIBC),transferrin saturation(TS),hemoglobin(Hb)electrophoresis and genetic examination.Retrospective study and prospective study were performed with the results.Results:(1)A total of 72 patients underwent SI,TIBC and TS,and 55.56 %(40/72) patients had SI decreased,TIBC increased and TS decreased.(2) 92 serum samples from these patients had Hb electrophoresis,in which 31.52%(29/92) presented fast band.(3) In this study,there were 82.52%(85/103) deletional alpha-thalassaemia and 17.48%(18/103) non-deletional alpha-thalassaemia.(4) In 85 deletional alpha-thalassaemia,alpha0-thalassaemia was more than alpha+-thalassaemia.Conclusion:(1) Deletion form is the main form of ? thalassaemia in ChongQing.(2) alpha0-thalassaemia is less than alpha+-thalassaemia.(3) Genetic diagnosis is the gold standard for this disease.(4) It should be emphasized that antenatal screening and prenatal diagnosis are important for better lives of human beings.(5) Alpha-thalassaemia can affiliate nutritional iron deficiency anemia(NIDA).
9.Effect of Smad7 on the expression of TGF-?R,SMADs,and STRAP in the process of malignant transformation of human bronchial epithelial cells
Journal of Third Military Medical University 1983;0(03):-
Objective To analyze the effect of Smad7 on the expression of TGF-?R,R Smads and STRAP in the process of malignant transformation of immortalized human bronchial epithelial cells BEP2D.Methods Cells were cultured and protein were extracted from BEP2D,BERP35T2,BS7 and RS7 cells,then Western blotting was performed to examine the expression level of TGF-?RⅠ,TGF-?RⅡ,Smad2/3,Smad4 and STRAP.(Results) Stable transfection of Smad7 gene led to decreased expression of TGF-?RⅡ and increased expression of Smad2 and STRAP in both BEP2D and BERP35T2 cells.There were no changes in the expression of Smad3 and Smad4.Conclusion Overexpression of Smad7 leads to decreased expression of TGF-?R Ⅱ and increased expression of STRAP in BEP2D and BERP35T2 cells,which could be one of the mechanisms of the malignant transformation of BEP2D cells.
10.Effection of lung fluid clearance disturbance in late preterm infants with respiratory distress syndrome
International Journal of Pediatrics 2013;(3):217-219
In recent studies,it has been demonstrated that the clinical efficacy of surfactant is poor for late protein infants.Besides,this kind of infants have not infection or other risk factors that may lead to respiratory distress syndrome(RDS).Thus,it is speculated that the pathogenesis of RDS of late preterm infants is different from preterm infants.New researches show that,as the key point of Lung fluid transport via Epithelium,α-ENaC plays an important role in the pathogenesis of RDS of late preterm infants through the inhibition of lung fluid clearance and activity of surfactant.This review highlights the most important mechanisms of Lung fluid absorption barrier in RDS of late preterm infants.
