Subjects: The patients who were 16 years of old or more and diagnosed with mild (stage I) and moderate (stage II) hypertension. Method: Open, compared and controlled study. The study group involved 40 patients who performed qi-exercises for 45 minutes per day on 30 days. Control group included 33 patients used fludex. It was found that qi-exercises, but not fludex, had increased the duration of wave-E. There was significant increase of total diastolic duration in study group, but not in control group. Qi-exercises did not change significantly the peak of atrial systole-induced left ventricular filling flow velocity, but fludex provided significant decrease. Left ventricular dystolic function of subjects in study groups did not change, comparing with baseline.

From June, 1996 to October, 1997, we have carried on research the treatment by method of Qui training – vitality maintenance in the mild-moderate level (the first-second period) of primary hypertensive patients, In comparison with fluid-used control group (n=24), we have some following comments. - About the effect of the method of Qui-training-vital maintenance: The method of Chi Gong-vitality preserving has effect in decreasing the systolic and diastolic blood pressure (p<0,01), the systolic blood pressure decreased more than diastolic blood pressure. In Doppler cardiac ultrasonograph, cardiac output decreased but without statistic sense. The functional parameters of let ventricle changed little, without statistic sense (p>0,05). - About the effect of fludex: Fludex decreased the systolic and diastolic blood pressure (p<0,001). In Doppler cardiac ultrasonograph, cardiac output decreased (p<0,05). The functional parameters of left ventricle decreased (p<0,05), EF,% D increased. The subject is being expanded continuously.

Background: Congenital heart disease is a malformation which the prevalence of 8 \ufffd?among alive infants. If it is not being treated on time, these malformations will develop to severe complication. The most common cause of cerebral abscess is congenital heart disease in infants. Objectives:This study aims to learn about some related factors and close consequence of cerebral abscess in congenital cardiac children. Subjects and method:A retrospective and prospective study was conducted on 37 patients with congenital heart disease were suffered from a cerebral abscess since January 2001 to 31 March 2007. Results:The boys were dominant with sex ratio: 1.85/1. Average age of acquired abscess was 6.8 years, 34/37 (91.9%) patients had curable congenital heart disease, including 33/37 (89.2%) diagnosed of right-left shunt. In comparison with patients whom over 2 years old and did not acquire abscess due to congenital cardiac shunt right-left type, there was no significant difference in hemoglobin, hematocrit, erythrocyte and saturation cutannee 13.5% among 37 patients of study were deaths, 26.5% had neurological sequelae and 8.1% were relapses. The average duration of hospitalization was longer (25.7 days) and the average costs were 4,317,000 Vietnam dong. Conclusion: Cerebral abscess was late complication of congenital heart disease and it was very necessary to treat completely the malformation of congenital heart disease in order to prevent of severe complication.

Background: Down syndrome is a developmental disorder caused by an extra copy of chromosome 21, is a condition in which extra genetic material causes delays in the way a child develops, both mentally and physically. It affects about 1 in every 700 babies. The fetus having high risk for Down syndrome (OS) can be detected early by ultrasound. Objectives: The aim of the study is to find out some ultrasound markers that relate to OS fetus. Subjects and method: A descriptive study was carried out on 612 pregnant women with fetus \ufffd?12 weeks by ultrasound to detect abnormal markers in fetus. The fetus were diagnosed Down syndrome by analysis chromosome from amniocyte and monitor up to the neonate. Then, finding out association between OS fetus and ultrasound markers. Results: Among 612 pregnant women,36/12 pregnant women had abnormal imaging in fetus, 11/12 pregnant women had OS fetus. There were 12 pregnant women detected OS fetus. 6/12 OS fetus associated with the maker of nuchal skin fold (cut off 2: 3mm at the first trimester and 2: 6 mm at the second trimester): Detection rate (DR) was 50%; false positive rate (FOR): 0,83%. 3/12 OS fetus associated with the marker of duodenal atresia. DR was 25%; FOR: 0%. Conclusions: The two common markers associated with OS fetus: \r\n', u'the first marker was nuchal skin fold (with cut off 2: 3mm at the first trimester and > 6 mm at the second trimester) and the second marker was duodenal atresia. \r\n', u' \r\n', u'

Background: Impaired synthesis of adrenal hormones because of steroid 21 - hydroxylase deficiency is one of the common inborn errors of metabolism. The disease is caused by mutations in CYP21 gene and inherited as an autosomal recessive trait.Objectives: This study aims to detect some mutations in CYP21 gene as well as study the relationship between genotype - phenotype and the carriers in patients' family. Subjects and method:43 patients with classic 21 - hydroxylase deficiency and 10 patients' parents were analysed CYP21 gene by using PCR techniques with specific primer pairs. The data was collected and analysed by EpiInfo 6.04 and other common medical statistic method. Results:Among 43 children patients of congenital adrenal hyperplasia due to 21-hydroxylase deficiency, the rate between male and female was equavalent. The most frequent mutation causing steroid 21 - hydroxylase deficiency was deletion 8bp of exon 3. Then, was splicing site mutation of intron 2. The mutation of exon 1 (Pr030Leu) was also detected. About genotype - phenotype relationship, nearly all deletions 8bp (80%) and 12 splicing mutations (87.5%) were associated with salt - wasting phenotype. Conclusion: Parents were the carriers corresponding to the autosomal recessive rule.

Background: Reasonably and safe antibiotic uses not only benefit patients, but also limit the development of antibiotic-resistant bacteria. Objectives: To total up all antibiotics and their brand names used at Viet Duc Hospital; To describe and preliminarily evaluate the uses of antibiotics according to Altemeier classification. Subjects and method: The cross-sectional study was caried out on all patients at 11 clinical departments, who were treated by antibotics. Review medical records for information of antibiotic use and some related factors (pre-operative and post-operative diagnoses, kind of operations, type of operation according to Altemeier classification). Results and Conclusion: There were 9 classes of antibiotics with 25 antibiotics and 31 bran names used in Viet Duc Hospital. Antibiotics of beta-lactam class and imidazol were most commonly used. The rate of antibiotic prophylaxis was low, although clean wounds have been used many strong antibiotics such as cephalosporin III. In infected wounds, combination of Cefotaxom + Flagyl was used more common, but it notes that the situation of production ESBLs by bacteria was rather high in hospital settings. Microbiological tests weren\u2019t applied widely for infected operations.

Background: Cystic hygromas is a common abnormal event in obstetrics ultrasound, which is induced by a chromosome disorder; it is also one of the major causes inducing fetus\u2019s congenital malformation. Objective: Determining chromosomal aberration in nuchal cystic hygromas by FISH technique and outcomes the value of factors in prognosis fetuses with cystic hygroma. Subject and methods: 53 fetuses with cystic hygroma, which are detected by ultrasound scan, are analyzed by FISH technique. Compare results of FISH, band G chromosomal analysis, ultrasonographic abnormalities, followed the fetuses. Results: Chromosomal and FISH analysis give the same detection: abnormal chromosomes: 75.46%, the highest rate is Turner syndrome: 50.94%, normal chromosome: 24.53%. Abnormal chromosomal fetuses: multi-malformation, grim prognosis. Cystic hygroma with other malformation in scan: high rate chromosomal aberrations and septated hygroma, Turner syndrome fetuses have large cystic hygroma, 4/6 fetuses with normal chromosome and without other abnormal result scan have resolutions of hygroma in the second trimester, normal birth. Conclusions: Abnormal chromosomes: 75.46%. Prognosis is grim: abnormal chromosomes, other malformations in scan, large cystic, septated hygroma. Prognosis is better: normal chromosomes, without other ultrasonographic abnormalities, small cystic, nonseptated hygroma, resolution of cystic hygroma.
