Objective To discuss the influence of H1N1 influenza on maternal and fetal outcomes and obstetric management. Methods Totally, data were collected on 19 women, affected by H1N1 influenza and admitted to Shengjing Hospital of China Medical University from November 7, 2009 to December 15,2009, and retrospective analysis was performed on the maternal and fetal outcomes. Results Among the 19 cases, three were( 15. 8%, 3/19) in puerperium, who were all mild cases and recovered. Sixteen (84.2%, 16/19)women were diagnosed as H1N1 influenza during pregnancy, among which two in early pregnancy (12. 5%), seven (43. 8%) in mid-term pregnancy and seven (43. 8%) in late pregnancy. According to the severity of H1N1 influenza, six were mild cases (37. 5% ,6/16), two (12. 5% ,2/16)were severe cases and eight (50. 0% ,8/16)were critical. For these 16 pregnant women, thc two cases in early pregnancy (mild cases) were terminated after recovery from H1N1 influenza. Among the seven mid-term cases, four mild and one of the three severe and critical cases delivered till term, and two of the three severe and critical cases were delivered abdominally because of fetal death intrauterine or maternal severe complications at 27 or 23 weeks of gestation. All of the seven late pregnant cases underwent emergent cesarean section due to maternal or fetal reasons, and two fetuses died in the uterus at late pregnancy and five survived including four preterm babies and one full term baby. Altogether, nine cases (56. 3%, 9/16)underwent emergent cesarean section, and six babies born alive and five survived without any symptom of influenza, two women died (10. 5%,2/19) after the operation. Conclusions Pregnant women during late pregnancy infected by H1N1 influenza are susceptible to develop into severe and critical conditions. Termination of the pregnancy in time is effective in both life-saving of the mothers and babies and prevent neonatal infection against H1N1.

Objective To evaluate the diagnostic value of magnetic resonance imaging (MRI) on fetal ventriculomegaly identified through prenatal ultrasonography and the outcomes of these newborns were followed up. Methods From March 2006 to July 2008, MRI was performed on 135 pregnant women whose fetuses diagnosed as fetal ventriculomegaly at an average of 32 gestational weeks in Shengjing Hospital Affiliated to China Medical University. Mild ventriculomegaly was defined when the width of unilateral or bilaeral fetal cerebral ventricle triangle was 10-15 mm, moderate ventriculomegaly 16-20 mm and severe ventriculomegaly >20 mm. We introduced the Denver developmental screening test(DDST) to follow-up the mild ventriculomegaly and normal babies, confirmed by MRI, at 6-12 months after birth and a case-control study was conducted. The intelligence and growth of these infants were analyzed. Results (1) Diagnostic rate of fetal ventriculomegaly through MRI: Among the 135 gravidas, 60 (44.4%) showed isolated ventriculomegaly, 5 (3.7%) complicated with ventricular hemorrhage; 12 (8.9%) complicated with agenesis of corpus callosum (ACC) and 2 (1.5%) complicated with cerebellar hypoplasia, while 56 (41.5%) were normal. Seventy-nine cases had fetal ventriculomegaly on MRI and 15.2% (n=12) of them complicated with ACC. (2) Degree of fetal ventriculomegaly on MRI: Among the 60 isolated ventriculomegaly cases, 55 (91.7%) were mild and 5 (8.3%) moderate ones. Among the 5 cases complicated with ventricular hemorrhage, one was mild ventriculomegaly, and 4 moderate or severe cases. Among the 12 cases with ACC, 8(66.7%) were moderate ventriculomegaly and 4 (33.3%) severe cases. The 2 cases with cerebellar hypoplasia were both moderate ventriculomegaly fetuses. (3) Follow-up at 6-12 months after birth : thirty out (case group) of the 55 isolated ventriculomegaly cases, 38 out of the 56 normal babies and 42 babies with normal MRI results were followed up, and the later 80 cases were taken as control. Four infants (13.3%) in the case group and 10 (12.5%) in the control group showed abnormal or suspected results in DDST (P>0.05), the rest babies were all normal. (4) Clinical outcomes of the 79 ventriculomegaly fetuses diagnosed by MRI: thirty mild ventriculomegaly babies and 5 moderate ones were born at term and showed normal at follow ups. However, 7 gravidas were not compliant, 6 pregnancies were terminated, and 12 were last. Three of the 12 cases with ACC continued the pregnancy, and postnatal MRI of the babies showed the same with the prenatal MRI, 8 pregnancies were induced and one was lost. All of the 5 fetuses with ventricufar hemorrhage were induced and the prenatal diagnosis was confirmed by autopsy. One of the 2 fetuses with cerebellar hypoplasia was term delivered and diagnosed as cerebral palsy at the age of 6 months, and the other one was induced. Conclusions MRI is an indispensable complementary diagnostic method for fetal ventriculomegaly diagnosed through ultrasound. The development of intelligence and growth of babies born with mild isolated ventriculomegaly is the same as normal ones.

BACKGROUND: As a group of primary cells,stem cells have the potentials of self-renewal and multi-directional differentiation, and can replace the damaged cardiomyocytes to construct new vessels, and enable the asthenic heart to obtain the blood pumping function again.This study summarized the progress of stem cell transplantation in treating cardiovascular diseasesDATA SOURCES:A computer-based online search of Pubmed database was undertaken to identify English articles published from January 2000 to December 2005, the keywords were "stem cell transplantation, cardiovascular diseases".STUDY SELECTION: The articles were primarily checked, and the references of each literature were looked up. Inclusive criteria:articles correlated with the classification and the transplanted pathways of stem cells,the present status,problems and prospect of its basic and clinical application in treating cardiovascular diseases. Exclusive criteria: repetitive study or Meta analysis.DATA EXTRACTION:Totally 50 relative literatures were collected, and 31 of them accorded with the inclusive criteria,and the other 19 were excluded due to the old or repetitive contents. Of the 31 involved literatures, 19 were about the classification of stem cells used in cardiovascular system, 1 about the transplanted pathways of stem cells, 8 about the application of stem cells in treating cardiovascular diseases, and 3 about the existing problems and prospect.DATA SYNTHESIS:With the continuous improvement of living level and aging, cardiovascular diseases have become the main causes for death and disability in modern society.Stem cells have the potentials of multi-directional differentiation, and have become the main seed cells for cell replacement therapy, and provided important investigative and applicating field for the treatment of cardiovascular diseases. At present, there are many stem cells to be used in cardiovascular system, including embryonic stem cells, umbilical cord blood stem cells, peripheral blood stem cells, bone marrow stem cells, skeletal muscle satellite cells, myocardial stem cells, adipose tissue-derived stem cells, etc. The common pathways for stem cell transplantation are direct injection into myocardium,intracoronary artery injection and intravenous injection.Stem cell transplantation can treat cardiovascular diseases by promoting angiogenesis and myocardial regeneration, decreasing myocardial apoptosis and reducing myocardial collagen, then ameliorate the cardiac function, and breakthrough and progress have been made in both animal models and clinical studies. However, problems sill exist to be solved, and there is agreat distance to the routine clinical application.CONCLUSION: Stem cells are the important fields of the basic research and clinical application for preventing and treating cardiovascular diseases,thus it will provide powerful theoretical and practical supports for the more effective prevention and treatment of cardiovascular diseases to solving the key points and difficulties in cardiovascular diseases.

Objective To evaluate the diagnostic value of MRI in the cases suspected of ventriculomegaly by prenatal uhrasonography.Methods 104 patients of suspected fetal ventriculomegaly (VM) diagnosed by uhrasonography were included from the Shengjing Hospital,China Medical University from March 2006 to October 2007.All cases were divided into 4 groups based on the standard of Gaglioti:10-12 mm(66 cases),13-15 mm(22 cases),16-20 mm(14 cases),and 21-25 mm(2 cases);they included 75 eases of single intracerebroventricular expansion and 29 eases of double intracerebroventricular expansion.All of them were subjected to MRI scan within 48 h of uhrasonographic examination to determine the prenatal diagnosis by MRI pregnancy outcomes.Results Among the 26 072 cases who received prenatal uhrasonography,104 cases (0.39%) were VM. (1) MRI detected 3 cases (5%) in 10-12 mm group:one ease of cerebellar hypoplasia,vascular malformation,chest and abdominal anomalies each; 5 cases(23%)in 13 -15 mm group:one case of agenesis of corpus callosum (ACC),cerebral hemorrhage,cerebral hemorrhage with cerebral meningocele,cerebral meningocele,intracranial mass meningocele each; 6 cases(43% )in 16 -20 mm group:4 cases of ACC,one case of intraventricular hemorrhage and ACC combined with ventricular hemorrhage each; 2 cases in 21-25 mm group:one case of ACC and intraventricular hemorrhage each.(2) MRI detected 4 eases(5%) among 75 unilateral VM cases and 12 eases (41%) among 29 bilateral VM eases.The differences were significant (P＜0.01).MRI diagnosis rate was 15.38% (16 cases).Follow-up of the outcomes of the pregnancy showed induction of 0labor in 15 cases (14%) all of which were the same as MRI results on autopsy,full-term delivery of 88 cases,of which all the neonates were healthy.Conclusions When the expansion width is above 16 mm or bilateral VM is suspected by ultrasonography,we suggest MRI examination to determine fetal central nervous system disease.
