Objective To explore the effect of angiotensin Ⅱ antagonist on left ventricular hypertrophy(LVH) and insulin resistance in elderly patients with diabetes mellitus and hypertension. Methods One hundred and twenty elderly patients with diabetes mellitus and essential hypertension with LVH by echocardiography entered the study. Patients were randomized into the telmisartan (80～160 mg/d) group or perindopril (4～8 mg /d) group. After treatment of telmisartan or perindopril,patients were followed-up for 8 months.Plasma sample was collected from each patient before and after treatment of telmisartan or perindopril,respectively.Then plasma levels of cholesterol,fasting plasma glucose(FPG), insulin and Homeostasis Model Assessment Insulin Resistance (HOMA-IR) were investigated.The echocardiography before and after 8 months of treatment with telmisartan or perindopril were also examined. Results Data were analyzed and showed that: (1)After 8 months of treatment with telmisartan or perindopril, blood pressure was reduced from 159/101 to 142/89 mm Hg(P

OBJECTIVETo determine the origin of a supernumerary small marker chromosome found in a fetus using prenatal BACs-on-Beads (BoBs) and single nucleotide polymorphism array (SNP-array) assays.
METHODSThe fetal sample was subjected to chromosomal karyotyping and BoBs analysis, and the results were validated with genome-wide scanning using a SNP microarray.
RESULTSThe fetus was found to have a 47,XX,+mar karyotype. BoBs analysis indicated that there was an amplification between 18p11.32 and 18p11.21, which was verified by the SNP-array assay as a 18.3 Mb duplication occurring at 18p11.32q11.1.
CONCLUSIONThe karyotype of the fetus was determined as 47,XX,+der18(18p11.32?18q11.1::18q11.1?18p11.32). The duplication has involved important genes including SMCHD1, LPIN2 and TGIF1, which may result in severe malformations in the fetus.
