Objective To explore the roles of Notch2,Notch4 in hyperoxia induced lung injury in premature rats.Methods At the postnatal 1 day Sprague-Dawley premature rats were randomly assigned to about 85% hyperoxia group and air group.At the 1,7,14,21 days after exposed,8 rats of each group were used to evaluate expressions of Notch2,Notch4 in lungs by immunohistochemistry and the level of Nothch2,Notch4 mRNA by reverse transcription polymerase chain reaction(RT-PCR).Results Expressions of Notch2,Notch4 had their rules in rats′ different stages of development;85% oxygen exposed would change their tracks.Conclusion Prolonged 85% oxygen exposure result in abnormal expressions of Notch2 and Notch4 ,which is likely to lead to the pathogenesis of hyperoxic lung injure in premature rats.

Objective To investigate the correlation between prostacyclin synthase (prostaglandin I2 synthase, PGIS) gene rs5602 single nucleotide polymorphism and ischemia stroke in Chinese Han population. Methods The patients with ischemia stroke and healthy controls in Chinese Han population were enroled. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS) was used to detect the rs5602 polymorphism. Results A total of 297 patients with ischemic stroke (male 177 and female 120) and 291 healthy controls (male 165, female 126) over the same period were enroled. The frequencies of TT genotype (31. 1% vs. 43. 6% ; χ2 = 5. 773, P = 0. 016) and T alele (56. 8% vs. 65. 8% ; χ2 = 5. 793, P = 0. 016) in the male patients with ischemic stroke were significantly lower than those in the male healthy controls. Multivariate logistic regression analysis showed that the rs5602 TT genotype was a protective factor for ischemic stroke in male (odds ratio 0. 260, 95% confidence interval 0. 118-0. 570; P = 0. 001). Conclusions PGIS gene rs5602 polymorphism is associated with ischemic stroke in male in Chinese Han population.

Objective To share our experiences on integrated services in providing fetal diagnosis and postnatal treatment for congenital diaphragmatic hernia(CDH).Methods A retrospective analysis was conducted on 25 pregnancies diagnosed as CDH by both prenatal ultrasound and MRI in Maternal and Children Hospital of Guangdong Province from January 2012 to January 2014.All of the subjects received integral medical management including prenatal management (prenatal diagnosis and consultation), perinatal management (prenatal care and delivery) and neonatal treatment.Results Among the 25 CDH fetuses, 11 were mild, nine were moderate, and five were severe.One severe case, who was diagnosed at 26 gestational weeks, was aborted on demand of the mother.The other 24 cases continued their pregnancy and all delivered after 35 weeks including 13 cesarean sections (one due to twin pregnancy and 12 due to maternal demand) and 11 vaginal birth.The mean gestational age when CDH was diagnosed was (24.5 ± 3.5) weeks, and the 24 women delivered at an average of (37.5 ± 1.4) gestational weeks.The eleven mild cases accepted mask oxygenation.For those 13 moderate or severe CDH cases, all received dexamethasone to promote fetal lung maturity at 32 gestational weeks, seven were intubated before clamp the cord, and the other six did after.These 13 babies accepted high-frequency oscillation ventilation, with a median duration of 58 hours, and some of them treated with inhaled nitric oxide on requirement with a median duration of 52 hours.Except two cases died before operation, the rest 22 cases underwent neonatal surgery.One moderate case died at 48 hours after surgery due to pulmonary hypertension and respiratory failure.Another one severe case withdrew treatment at two months old.The other 20 infants recovered fully.Conclusions Integrated management including prenatal diagnosis and postnatal treatment, provides an effective and streamlined mode for diagnosis and treatment of CDH.Therefore,it might minimize potential medical risks.

Purpose To investigate TRAP1 expression in esophageal cancer and its relationship with clinicopathological features and prognosis.Methods Expression levels of TRAP1 in 60 pairs of cancer and adjacent normal tissues were detected by immunohistochemistry,and the relevance between TRAP1 and clinicopathological features was evaluated.Kaplan-Meier and Cox proportional regression analyses were performed to determine the association of TRAP 1 expression and survival of the patients.Results The positive expression rate of TRAP1 was 55.0％,and the amount of relative protein transcript level was 2.7 ± 1.1 in the cancer tissue.The positive expression rate of TRAP1 was 11.7％,and the relative expression protein was 0.5 ± 0.4 in the adjacent normal tissue.The expression level of TRAP1 in cancerous tissue was significantly higher than that of tissue adjacent to carcinoma.There was no statistically significant difference between the expression levels of TRAP1 with sex,age,location,and degree of differentiation (P ＞ 0.05).There was statistically significant relationship between recurrence,metastasis and TNM stages with the expression of TRAP1 levels (P ＜ 0.05).The average survival time of TRAP1-negative patients was 69.0 months (95％ CI:60.2-77.9) while the TRAP1-positive patients was 34.2 months (95％ CI:24.4-44.1).High levels of TRAP1 were correlated with decreased survival of postoperative esophageal cancer patients (P ＜ 0.05).Conclusion TRAP1 is overexpressed in esophageal cancer and associated with the progression and prognosis of esophageal cancer.
