Journal of Applied Clinical Pediatrics 2006;0(13):-
Objective To investigate the relationship between the insertion/deletion(I/D) polymorphism of the angiotensin convcer-(ting) enzyme(ACE) gene and congenital heart disease(CHD) and to quest the predisposing gene of congenital heart disease by analyzing the polymorphism of the ACE gene in patients with CHD.Methods Sixty-eight patients with CHD were served as observing group,sixty-four patients without CHD as control group.We drew DNA of leukocyte from blood by the method of saturation phenol and chloroform and we amplified the ACE gene using the DNA polymerase chain reaction technique.The amplification products were employed electrohoresis in 2% sepharose.the polymorphism of the angiotensin converting enzyme gene was analyzed under ultraviolet lump.Results In the obser-(ving) group,the genotype distribution frequency of the ACE was II in 12(17.65%),DD in 32(47.06%) and ID in 24(35.29%),and in the control group,it was II in 20(31.25%),DD in 10(15.63%) and ID in 34(53.12%).Conclusions The study result clarifies that CHD has close correlation to the polymorphism of the angiotensin converting enzyme gene.The relative risk of DD genotype is higher than that of the others,and DD genotype possibly is the predisposing genotype of CHD D allele perhaps is the susceptibility gene of CHD.

Objective To detect the routine coagulation indicators in breast cancer patients receiving the trastuzumab treatment and to analyze the influence of the coagulation indicators on clinical treatment response .Methods Totally 67 hospitalized breast cancer patients receiving the trastuzumab treatment in 401 Hospital of PLA from Jan .2006 to Dec .2012 were collected and divided into the effective group(47 cases) and ineffective group(20 cases) according to the curative effect .The levels of PT ,APTT ,TT ,Fib and D‐D were statistically analyzed .The differences of coagulation indicators were compared between the two groups .The correla‐tion between the coagulation indicators with the curative effect was analyzed .Results Compared with the effective group ,PT , APTT and TT in the ineffective group were slightly extended ,while the D‐D level was slightly increased ,the differences were not statistically significant(P> 0 .05);but the Fib level was significantly increased with statistical difference(P< 0 .05) .Conclusion The breast cancer patients with ineffectiveness in the trastuzumab treatment are easily appear the high Fib status .Determining its plas‐ma concentration is conducive to judge the prognosis of the trastuzumab treatment in breast cancer patients .

Objective To identify risk factors associated with repeat use of pulmonary surfactant ( PS) in the treatment of respiratory distress syndrome ( RDS ) in the term and near-term neonate. Methods There were 130term and near-term new borns with RDS who were treated with pulmonary surfactant were enrolled. These infants were categorized into two groups: single-dose group (85 cases) and repeat-dose group (45 cases). The differences in basic information were compared between the two groups, and logistic regression analysis was used to identify the risk factors for repeat use of pulmonary surfactant.Results TherepeatutilizationrateofPSwas34.6℅.The incidence of asphyxia,maternal gestational hypertension, X-ray RDS grade 3-4, the age of first dose PS,respiratory support time in the repeat-dose group was significantly higher than in the single-dose group (P<0. 05). PaO2/FiO2 and the cure rate in the repeat-dose group were significantly lower than in single-dose group ( P<0. 05 ) . The incidence of sepsis, pulmonary hemorrhage, shock and patent ductus arteriosus ( PDA) in the repeat-dose group was significantly higher than in the single-dose group ( P<0. 05). Further logistic regression analysis showed that birth asphyxia ( OR=5. 674 , 95℅CI 1. 378 -23. 354 , the age of first dose of PS (OR=1.092, 95℅CI 1.002 -1.191)and PDA(OR =23.499, 95℅CI 2.348 -235.152)were the independent risk factors for repeat use of pulmonary surfactant.Conclusions Birth asphyxia,the age of first dose PS and PDA are the risk factors for repeat use of pulmonary surfactant in the treatment of RDS in the term and near -term neonate.

Objective To share our experiences on integrated services in providing fetal diagnosis and postnatal treatment for congenital diaphragmatic hernia(CDH).Methods A retrospective analysis was conducted on 25 pregnancies diagnosed as CDH by both prenatal ultrasound and MRI in Maternal and Children Hospital of Guangdong Province from January 2012 to January 2014.All of the subjects received integral medical management including prenatal management (prenatal diagnosis and consultation), perinatal management (prenatal care and delivery) and neonatal treatment.Results Among the 25 CDH fetuses, 11 were mild, nine were moderate, and five were severe.One severe case, who was diagnosed at 26 gestational weeks, was aborted on demand of the mother.The other 24 cases continued their pregnancy and all delivered after 35 weeks including 13 cesarean sections (one due to twin pregnancy and 12 due to maternal demand) and 11 vaginal birth.The mean gestational age when CDH was diagnosed was (24.5 ± 3.5) weeks, and the 24 women delivered at an average of (37.5 ± 1.4) gestational weeks.The eleven mild cases accepted mask oxygenation.For those 13 moderate or severe CDH cases, all received dexamethasone to promote fetal lung maturity at 32 gestational weeks, seven were intubated before clamp the cord, and the other six did after.These 13 babies accepted high-frequency oscillation ventilation, with a median duration of 58 hours, and some of them treated with inhaled nitric oxide on requirement with a median duration of 52 hours.Except two cases died before operation, the rest 22 cases underwent neonatal surgery.One moderate case died at 48 hours after surgery due to pulmonary hypertension and respiratory failure.Another one severe case withdrew treatment at two months old.The other 20 infants recovered fully.Conclusions Integrated management including prenatal diagnosis and postnatal treatment, provides an effective and streamlined mode for diagnosis and treatment of CDH.Therefore,it might minimize potential medical risks.

OBJECTIVE Identify the effect of Brandt-Daroff exercises for positional vertigo with atypical positioning nystagmus.METHODS 11 cases of positional vertigo during 2006~2007 with atypical positioning nystagmus when carrying Dix-Hallpike and roll test,the nystagmus had the follwing characters:poly-positions,atypical direction,long lasting(more than 3 mins),no fatigue.After ruling out centrul neural system disorders,the patients were instructed to do Brandt-Daroff exercises 2-3 times/day,and 6-10 times every time.RESULTS After doing the exercises for 3-4 days,the vertigo of all the 11 cases were all relieved.After 1-2 weeks,10 cases were cured,syptom of the other 1 was relieved significantly,and the nystagmus was alleviated.CONCLUSION Cases with atypical positioning nystagmus may present a different kind of BPPV related with the otolith and vestibular nerve disease.Brandt-Daroff exercises was a good method for the atypical positioning nystagmus cases.
