1.Influence of Different Positive End Expiratory Pressure Level on Ventilative Efficiency for Premature Infant with Respiratory Distress
Journal of Applied Clinical Pediatrics 2006;0(18):-
Objective To explore influence of different positive end expiratory pressure(PEEP)level on ventilative efficincy of premature infant with respiratory distress syndrome(RDS).Methods Forty preterm infants who were diagnosed RDS and needed ventilation were randomly assigned to lower PEEP(0.49~0.59 kPa)and high PEEP(0.59~0.78 kPa)group.They were treated by ventilation and pulmonary surfactant(PS).When they were medically stable,blood gas was done at 15 min,2,6,12,24 h after ventilation.Then the ratio of pa(O2)/FiO2,oxygen index(OI),ventilation index were calculated.Result The ratio of pa(O2)/FiO2,OI,ventilation index were better in lower PEEP group than those in high PEEP group(Pa
2.Effects of Dopamine and Dobutamine on Endocrine of Premature Infants with Hypotension
Journal of Applied Clinical Pediatrics 2004;0(08):-
Objective To explore the effects of dopamine and dobutamine on thyroid stimulating hormone(TSH),total thyroxine(T4) and growth hormone(GH) in preterm infants with hypotension.Methods Forty-seven preterm infants with hypotension were enrolled in the stu-dy,and 38 preterm infants remained hypotensive after two dose of isotonic saline solution,who were divided into two groups and assigned to receive dopamine or dobutamine.Drug infusion were all started at 4 ?g /(kg?min) and the dose increased by 2 ?g /(kg?min) in a stepwise fashion until either the mean blood pressure normalized or a maximal dose 20 ?g /(kg?min) was reached.Haemodynamic variables and se-rum levels of TSH,T4,and GH were assessed during the first 72 h of treatment and the first 3 d after stopping treatment.Microplate luminometer was used to test TSH,T4,GH levels.Results Necessary cumulative and mean drug doses and maximum infusion required to normalize blood pressure were significantly higher in the dobutamine group than those in the dopamine group(Pa0.05].Conclusions Dopamine and dobutamine both increase the syste-mic blood pressure,with higher drug doses in dobutamine group.Dopamine reduces levels of serum TSH,T4 and GH in preterm infants but such suppression is quickly reversed after treatment is stopped.

Differential display-PCR was used to clone the differential expressed genes between Mycobacterium tuberculosis virulence strain H37Rv and its avirulent mutant H37Ra. All of different genes were cloned, sequenced and some were analyzed by Northern-blotting. Two cDNAs that appeared to be expressed in H37Rv, but not in H37Ra, were cloned and sequenced. Rv0170, and Rv1894c, code for proteins with unknown functions. The two gene were present in H37Ra, but not expressed. These results show that mRNA DD methodology can represent a potential tool for investigation of M. tuberculosis gene expression.

Objective To investigate the expression of nicotinic acetylcholine receptor (nAchR) subunits, and the effects of smoking on its expression in peripheral blood mononuclear cells (PBMCs). Methods Blood was collected from 92 healthy male smokers and 36 healthy male non-smokers. Peripheral blood monocytic cells were obtained, and reverse transcription-polymerase chain reaction (RT-PCR) was employed to study the gene expression of 11 nAchR subunits (?2-?7, ?9, ?10, ?2-?4). Results The results showed that the PBMCs of smokers and non-smokers appeared to express ?2, ?5, ?6 and ?7 only out of 11 nAchR subunits. However, the expression of ?5 and ?7 subunits was lower in smokers′ PBMCs than in non-smokers′ (P
