Objective To investigate the iron status in the newborns of maternal gestational diabetes mellitus(GDM) women,and explore the mechanism of iron deficiency in these newborns.Methods From June 2008 to October 2011,64 GDM women (GDM group) and 71 healthy pregnant women (control group)who delivered in the Second Affiliated Hospital of Wenzhou Medical College and their newborns were studied prospectively.Serum ferritin (SF),serum transferrin receptor (sTfR),erythropoietin (Epo),haemoglobin (Hb),serum level of insulin and plasma glucose in cord blood was measured.The neonatal birth weight (BW) and birth weight Z Score(WAZ) was recorded.The concentrations of serum fasting insulin (FINS),fasting plasma glucose (FPG) and glycosylated hemoglobin (HbA1c)were tested for all the women before delivery.Results In the GDM group,the cord blood sTfR,Epo and serum level of insulin was (42 ± 10)nmol/L,(56 ±41) U/L and(18 ± 5) U/L,respectively.While in the control group,these were(35 ± 8)nmol/L,(41 ± 43) U/L and (10 ± 5) U/L,respectively.The cord blood sTfR,Epo and serum level of insulin in the GDM group were significantly higher than those in the control group (P ＜ 0.05).The cord blood SF in the GDM group[(60 ±36) μg/L] was significantly lower than that of the control group[(146 ±38) μg/L,P ＜ 0.01].The neonatal BW and WAZ in the GDM group [(3615 ± 538) g and 0.558] were significantly higher than those in the control group [(3449 ± 423) g and 0.224,P ＜ 0.05].No significant difference was found in the cord blood plasma glucose and Hb between the GDM group[(3.3 ± 1.0) mmol/L and (181 ± 18) g/L] and the control group [(3.0 ± 0.8) mmol/L and (176 ± 16) g/L,P ＞ 0.05].The FINS and HbA1c of the GDM group[(12.5 ±5.0) U/L and (6.5 ±0.7)％] were significantly higher than those in the control group [(10.9 ± 4.3) U/L and (5.3 ± 0.7) ％,P ＜ 0.05].The FPG of the GDM group and the control group were (5.3 ± 1.2) and (5.0 ± 1.0) mmol/L,respectively,with no statistically significant difference (P ＞ 0.05).Conclusion Maternal GDM may related to the iron deficiency of the newborns.

Objective To summarize the key nursing points in patients with monochorionic twins undergoing selective feticide with bipolar electrocoagulation.Methods Selective feticide with bipolar electrocoagulation were performed in 68 monochorionic twins with one twin anomaly.And the perioperative care was performed on the patients.Results Operations were accomplished successfully in 68 cases.No complications,such as infections,premature rupture of membrane and so on,were found in all cases seven days after operation.Conclusions The nursing key points include preoperative psychological nursing by interpretation of the operations,monitoring fetal heart sounds during operations,and close observation of body temperature,uterine contractions and fetal heart rate in pregnant women after operations.Careful perioperative nursing is helpful for improvement of operative success and to ensure normal development of fetus.

Objective To investigate outcome and prognosis of isolated mild fetal ventriculomegaly (IMV) of fetus in uterus. Methods From Jan. 2006 to Dec. 2009, 18 200 singleton pregnancy women from 20 weeks gestation underwent prenatal ultrasonography examination in Department of Obstetrics and Gynecology, Second Affiliated Hospital of Wenzhou Medical College. One hundred and forty-eight women with IMV (transverse diameter of the atrium of the lateral ventricle measuring between 10 and 15 mm with no other abnormalities) were studied prospectively, which were divided into two groups: 99 women with transverse diameter of the lateral ventricle of 10 - 11 mm in group A and 49 women with transverse diameter lateral ventricle of 12 - 15 mm in group B. The changes of ventriculomegaly and the associated intracranial and extracranial anomalies were observed regularly every 2 or 4 weeks until delivery. The development of neurological system was also followed up. Results ( 1 ) The overall incidence of IMV was 0. 08% (148/18 200). The rate of bilateral ventriculomegaly were 20% (20/99) in group A and 51% (25/49) in group B, which reached statistical difference (P＜ 0. 05). (2) Prognosis of fetus: 139 cases with 2 or more ultrasonographic examinations, IMV resolved throughout pregnancy in 41. 7% (58/139) ,regressed in 7. 9% (11/139) ,remained stable in 36. 7% (51/139)and progressed in 13. 7% ( 19/139). Five cases in group A and 11 cases in group B present progress, which reached significantly difference (P ＜ 0. 05). (3) One hundred and eleven cases infant were followed up for 5-12 months,the rate of psycho-motor developmental delay was 5. 4% (6/111). The rate of neuro-developmental delay in progressed group (3/15) was higher than 2. 5% ( 1/40) in resolved group, 0 (0/8) in regressed group and 4. 2% (2/48) in remained stable group, which reached significantly difference (P＜0. 05). Conclusions About 85% of cases of IMV resolved, regressed or remained stable in utero would exhibited good prognosis. IMV with a transverse atrial size ≥ 12 mm or progression in utero was usually associated with a poor prognosis, which should be observed carefully.

Objective To detect fibrillin-1 gene (FBN1) mutations in patients with Marfan syndrome (MFS) by denaturing high-pedormance liquid chromatography (DHPLC) and DNA sequencing. Methods Genomic DNA was extracted from whole blood sample of 22 MFS patients. All 65 exens of FBN1 were amplified by polymerase chain reaction(PCR) respectively. Mutations were screened by DHPLC followed by DNA sequencing of the PCR products which showed different DHPLC profiles from the normals. Results Ten mutations of the FBN1 were found in 9 MFS patients. The mutations comprised four missense[5015G > C(C1672S),5309G > A(C1770Y),7241G > A(A2414G) and 7769G > A(C2590Y)], four nonsense [3295G > T ( E1099X ), 430"/insTCGT (G1441X), 4621C > T ( R1541X ) and 8080C > T (A2694X)], and two splice site mutations (IVS29 + 4A > T and IVSSO + 1G > A). Conclusion It is suggested that DHPLC coupled with DNA sequencing is an efficient method for the detection of FBN1 gene mutations, and it may be useful in diagnosis of MFS.

[Objective] To summarize the perioperative nursing points during the amnioreduction by fast and negative pressure drainage.[Methods] Amniodrainage and associated nursing care were performed in 93 hydramnios cases of pregnant women from January 2006 to December 2010,and the nursing key points were summarized.[Results] Operations were performed successfully in 93 hydramnios cases of pregnant women.No complications occurred in 92 eases 3 d after operation.Bellyache and uterine contraction occurred in one case 2h after operation,which indicated placental abruption,two dead fetuses were got out by cesarean section.[Conclusions] The nursing key points included preoperative psychological nursing by interpretation of the operation,monitoring fetal heart sounds and close observation of contrac-tions in pregnant women.Careful perioperative nursing for patients with hydramnios is important to improve the success rate and reduce postoperative complications.

To search for nasopharyngeal carcinoma (NPC) biomarkers,laser capture microdissection (LCM) was used to purify the target cells from NPC and normal nasopharyngeal epithelial tissues (NNET). Two-dimensional gel electrophoresis (2-DE) was performed to separate the total proteins of microdissected NPC and NNEC,PDQuest software was applied to analyze 2-DE images,and the differential protein spots between the two types of tissues were identified by both MALDI-TOF-MS and ESI-Q-TOF-MS. The expression of cytokeratin 8(CK8),one of the differential proteins,in the microdissected NPC and NNEC as well as 4 NPC cell lines with different differentiated degrees and/or metastatic potentials was detected by Western blot. Immunohistochemistry was also used to detect the expression of CK8 in paraffin-embedded tissues including 63 cases of primary NPC,28 cases of NNET and 20 cases of cervical lymphonode metastasis. In the present study,2-DE patterns of microdissected NPC and NNEC were established,and 29 differential proteins in the above two tissues were identified,of which 15 only expressed or up-regulated in NPC and 14 only expressed or up-regulated in NNET. The expression level of differential protein CK8 between the NPC and NNET was selectively confirmed,and was found to be related to the differentiation and/or metastasis of NPC cell lines. Significant down-regulation of CK8 was observed in NPC compared with NNET,and significant up-regulation of CK8 was also observed in lymphonode metastasis compared with primary NPC. The data suggest that CK8 may be related to the differentiation and lymphonode metastasis of NPC,and may serve as molecular biomarkers for metastasis and differentiation of NPC.
