Fetal reduction by bipolar cord coagulation in managing complicated monochorionic multiple pregnancies: preliminary experience in China.

Background: Monochorionic multiple pregnancies (MMPs) are associated with higher rates of perinatal morbidity and mortality caused by interfetal vascular anastomoses in the monochorionic placenta, which can lead to fetal health interactions. In some circumstances, selective feticide of the affected fetus is necessary to save the healthy co-twin. We evaluated the effects and safety of our initial experiences using bipolar cord coagulation for the management of complicated MMPs.

[Prevalence of hypertension in the Guangxi Bai Ku Yao populations].

Objective: To observe the prevalence of hypertension and associated risk factors in the Guangxi Bai Ku Yao populations.

Methods: A total of 1170 subjects of Bai Ku Yao aged 15 and over were surveyed by a stratified randomized cluster sampling. Blood pressure, body height, weight, waist circumference, serum lipid and apolipoprotein levels were measured, and body mass index (BMI) were calculated, matched 1173 subjects of Han Chinese from the same region served as control.

[Comparison between transabdominal and transcervical chorionic villus sampling in clinical application for prenatal diagnosis].

Objective: To compare transabdominal and transcervical chorionic villus sampling (TC-CVS) in application for prenatal diagnosis, and to summarize the experience of transabdominal chorionic villus sampling (TA-CVS).

Methods: One hundred and nine TA-CVS between April 2005 and November 2007 and 69 TC-CVS between August 1999 and March 2005 were retrospectively analyzed.

Results: (1) The mean gestational age was (12.

[Bipolar coagulation used in selective feticide of monochorionic twins with one twin anomaly].

Objective: To summarize our preliminary experience of selective feticide with bipolar coagulation in complicated monochorionic twins (MCT), and discuss the clinical application of feticide in discordant MCT.

Methods: Three MCT with one twin anomaly, in which 2 had severe twin-twin transfusion syndrome (TTTS), stage IV, and 1 had acardiac twin, were identified in the second trimester of pregnancy. To terminate the abnormal twin and isolate the co-twin's circulation completely, selective feticide was performed by umbilical cord occlusion with bipolar coagulation under guidance of ultrasound and fetoscopy.

[Clinical study and prenatal diagnosis of fetus with shortened long bones].

Objective: To investigate the manifestations and prenatal diagnosis of the fetus with shortened long bones.

Methods: Ultrasonography was conducted on 57 fetuses with shortened long bones and 62 normal fetuses. Percutaneous umbilical blood sampling was performed on the 57 cases to undergo examination of karyotype and mutation in exon 10 of fibroblast growth factor receptor (FGFR)3 gene.
