Surgical repair of gastroschisis complicated by tracheostenosis in a very premature infant / 中华围产医学杂志

We describe the diagnosis and treatment of a very premature female infant with gastroschisis complicated by tracheostenosis. The pregnant woman, whose fetus was diagnosed with gastroschisis by ultrasound at 22 weeks in a local hospital, was admitted to the Second Affiliated Hospital of Wenzhou Medical University at 28 +1 weeks with oligohydramnios. Ultrasound after admission confirmed the previous diagnosis. A live baby girl was born by vaginal breech delivery at 29 +1 weeks after spontaneous rupture of the membranes. Because of the unstable oxygen saturation, the neonate finally received Silo in the delivery room prior to the closure of abdominal fissure 7 d after birth, and during the placement difficult endotracheal intubation was evident. She was diagnosed with having congenital tracheal stenosis via chest CT scans with 3-dimensional reconstruction 3 weeks after birth and received transbronchoscopic balloon dilatation at 3 months after birth. During the 2-year follow-up, she grew well without any complications.

Correlation of insulin-like growth factor 1 expression in placenta with DNA methylation and fetal macrosomia / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To explore the correlation between methylation of insulin-like growth factor 1 (IGF-1) gene promoter and its placenta-specific expression and fetal macrosoma.</p><p><b>METHODS</b>One hundred twenty nine healthy pregnant women were recruited between April 2011 and March 2012. Baseline data were collected with self-report questionnaires. Real-time quantitative PCR was used to determine the expression of IGF-1 mRNA in the placenta. Methylation level of the IGF 1 gene was determined with matrix-assisted laser desorption/ionization-time of flight mass spectrometry.</p><p><b>RESULTS</b>The expression of IGF-1 in placenta and its methylation level showed no significant difference between macrosomic fetuses and controls. No linear correlation was found between IGF-1 mRNA expression and methylation level of IGF-1 promoter (r=0.128, P=0.295). IGF-1 promoter region in placenta showed a hypomethylation status. However, a positive correlation was found between IGF-1 expression and birth weight below 4260 g (r=0.264, P=0.022). The expression of IGF-1 mRNA was significantly higher in those with a birth weight below 4260 g, which suggested that placental IGF-1 expression may contribute to increased birth weight. In regard to fetal overgrowth, however, there seemed to be a negative correlation in which placental IGF-1 expression was downregulated to limit fetal overgrowth.</p><p><b>CONCLUSION</b>No linear correlation was found between placental IGF-1 expression and methylation level of IGF-1 promoter with a hypomethylation status. The contribution of placental IGF-1 expression to birth weight is bidirectional. Increased expression seems to promote fetal growth, while decreased expressions may curb overgrowth, therefore control fetal growth in a relatively normal range.</p>

Drug resistance of Helicobacter pylori in nodular gastritis in children / 临床儿科杂志

Objective To analyze the drug resistance of Helicobacter pylori (H.pylori) in nodular gastritis in children and to further explore the rational use of antibiotics for drug-resistant H.pylori strains. Methods A total of 473 children with upper gastrointestinal symptoms undergoing gastroscopy from January 2013 to June 2014 in our hospital were enrolled. Two pieces of gastric antral mucosa in children with nodular gastritis were collected for H.pylori rapid urease test and H.pylori culture. The resistance of H.pylori to amoxicillin, clarithromycin, metronidazole, moxilfoxacin and levolfoxacin was detected by agar dilution method and E-test. Results In 473 cases of nodular gastritis, 258 cases were H.pylori culture-positive. The resistance rate of H. pylori isolates to amoxicillin, clarithromycin, metronidazole, moxilfoxacin, levolfoxacin was 6.2%, 34.9%, 49.2%, 8.9%and 5.0%, respectively. Dual resistance to clarithromycin and metronidazole was 23.3%. Moreover, 405 cases had a family history of H.pylori infection. Conclusions Nodular gastritis is a special sign of H.pylori infection in children. H.pylori infection has obvious familial aggregation. The low resistance rate of H.pylori to amoxicillin in children with nodular gastritis indicates that amoxicillin can be used as the main drug for eradication of H.pylori. Meanwhile, clarithromycin should be applied according to the drug sensitive test due to high resistance rate of H.pylori to clarithromycin.

Effects of isocorydione on cell proliferation in SiHa human cervi-cal carcinoma cell lines / 中国肿瘤临床

Objective:This paper aimed to investigate the effects of isocorydinone on cell proliferation in SiHa human cervical carcinoma cell lines. Methods:Different concentrations of isocorydione (100, 200, 400, 800, and 1200 μmol/L) were used to treat SiHa human cervical carcinoma cells in vitro for 24, 48, and 72 h. Methyl thiazolyl tetrazolium (MTT) assays were conducted to determine the inhibitory action of isocorydione. Flow cytometry was performed to detect the cell cycle in SiHa human cervical carcinoma cells af-ter treatment with 400 μmol/L isocorydione. Hoechst 33342 staining was used to observe the micro-morphological changes of SiHa cell nucleus after the treatment. The expression of Bcl-2, Bax, and caspase-3 proteins in cervical carcinoma SiHa cell lines was determined using western blot analysis. Results: MTT assays showed that isocorydione inhibits the proliferation of SiHa cells in a dose- and time-dependent manner (P<0.05). The flow cytometry results showed that SiHa cervical carcinoma cells treated with different concen-trations of isocorydione exhibited increased cell cycle. Compared with the control group, Hoechst 33342 staining showed that SiHa cells became narrow, with nuclear pyknosis and fragmentation, and formed an apoptotic body after treatment with 400 μmol/L isocoryd-ione for 48 h. Furthermore, western blot analysis proved that isocorydione significantly inhibited the proliferation of SiHa cell lines, and the expression of Bax protein was increased. By contrast, the expression of Bcl-2 protein decreased gradually. Consequently, the ra-tio of Bax/Bcl-2 increased, as well as the expression of caspase-3 protein. Conclusion:Isocorydione exhibited an overt inhibitory ac-tion on SiHa cells. Isocorydione promoted the occurrence of cell apoptosis, which may be associated with related proteins of mitochon-drial apoptotic pathway.
