1.Gastrointestinal mucin genes
International Journal of Pediatrics 2012;39(1):11-15
The incidence of gastrointestinal diseases increases every year.Etiology and pathogenesis of gastrointestinal diseases have been not yet elucidated,such as inflammatory bowel disease,gastrointestinal cancers,and allergic diseases.In recent years,the role of mucin genes expression in gastrointestinal diseases has been paying much attention to.Studies have shown that mucins are the main component of mucus in the digestive tract,and a major factor in the formation of the gastrointestinal barrier.Mucins are related to gastrointestinal epithelium,intestinal microflora and inflammatory factors.Abnormal expression of gastrointestinal mucin genes,especially MUC1 and MUC2,are related to Gastrointestinal inflammation and cancer.Currently gastrointestinal mucin genes expression contribute to exploring the diagnosis,treatment and prognosis of digestive diseases.This study is to summarize the progress in gastrointestinal mucin genes expression.
2.Diagnosis and treatment in children with refractory idiopathic thrombocytopenic purpura
International Journal of Pediatrics 2012;39(3):254-257
Idiopathic thrombocytopenic purpura (ITP),also called immune thrombocytopenia more frequently by the international,is the most common acquired hemorrhagic disease characterized by thrombocytopenia,presence of anti-platelet antibody in the plasma,with increased or normal megakaryocytes with abnormal maturation.About 70% of 1TP patients recover spontaneously within 6 months,while a small proportion of patients will transform to persistent,chronic or refractory idiopathic thrombocytopenic purpura.New immunosuppressive agents and thrombopoietin for the treatment of children with refractory ITP have been developed.Dramaric progresses in the diagnostis,severity assessment and treatment of refractory ITP have been made recently,which is comprehensively illustrated in this review.

4.Efficacy and Influence of Rat NGF on Serum Neuropeptide Y and Neuron-specificenolase Levels in New-born with Neonatal Hypoxic and Ischemic Encephalopathy
China Pharmacist 2015;(8):1336-1338
To discuss the therapeutic effect and influence of rat NGF on serum neuropeptide Y ( NPY) and neuron-specificenolase (NSE) levels in newborn with neonatal hypoxic and ischemic encephalopathy (HIE). Methods: Totally 70 cases of neonatal HIE patients were selected and divided into the observation group and the control group at random. The children in the two groups were given the routine medical treatment such as oxygen uptake, the control of intracranial pressure, blood pressure and blood sugar, anticonvulsant, balance of water and electrolyte and etc. The children in the observation group were additionally given 20μg rat NGF through intramuscular injection once a day. The children in the control group were additionally given 100 mg citicoline through in-travenous drip once a day. The treatment course was 10-14 days. The changes of serum NPY and NSE levels, clinical curative effect and adverse drug reactions ( ADR) in the two groups were compared, and the occurrence of nervous system sequel after the medical treatment was compared and followed up. Results: After the 2-week medical treatment, the serum NPY and NSE levels in the two groups were declined (P<0. 05 or P<0. 01), and the declining in the observation group was more notable than that in the control group (P<0. 05). The total clinical efficiency in the observation group was 94. 28%, which was much higher than that (68. 57%) in the control group (P<0. 01). No obvious adverse drug reaction appeared in the two groups during the treatment. After the one-year follow up, the occurrence of sequel was 5. 71% in the observation group, which was much lower than that (22. 86%) in the control group(P<0. 05). Conclusion:Rat NGF has reliable curative effect on neonatal HIE with high security, which can improve the repair of impaired neuronal cells, reduce the occurrence of sequel of neuronal cells and enhance the prognosis, and the mechanism may relat-ed with the reduction of serum NPY and NSE levels.
5.Prenatal ultrasound diagnosis of persistent right umbilical vein and its complicated abnormalities
Chinese Journal of Perinatal Medicine 2012;15(7):416-419
Objective To investigate the value of prenatal ultrasound in diagnosing fetal persistent right umbilical vein (PRUV) and structural malformations.Methods From April 2007 to August 2011,38 827 pregnant women in Obstetrics and Gynecology Hospital of Fudan University accepted ultrasound examination,among which 109 fetuses were found PRUV.The relation between PRUV and other structural abnormalities was retrospectively analyzed.Results The incidence of PRUV was 0.28% (109/38 827) including 100 singletons and 9 twins.Among the 109 cases of PRUV confirmed by the prenatal ultrasound diagnosis,95 cases did not complicate with fetal structural abnormality (90 singletons,5 twins),and had normal deliveries with healthy infants.Four infants were tested for their chromosomes and got normal results.The rest 14 fetuses with PRUV suffered from fetal structural abnormality (12.8%,14/109),among which,10 fetus (71.4%,10/14) suffered from cardiovascular abnormality such as endocrinal cushion defeats,double outlet right ventricle,single atrium and single ventricle.Nine pregnant women accepted artificial terminations.Only one of the 14 fetuses had chromosome test and got normal result.Conclusions Once PRUV was diagnosed by prenatal ultrasound,it is suggested to check the fetus carefully,especially the cardiovascular system.
