ABSTRACT
Objective: To investigate the changes of urinary S100B protein concentrations and their relationship with brain damage in preterm infants there of . Methods: The urinary S100B protein of 84 preterm infants and 26 full term infants, which were used as control, were measured at 24 h and 120 h after birth. At the same time, routine clinical observations, neurologic patterns and ultrasound screens were recorded. The value of urinary S100B protein and brain damage were evaluated in preterm infants with different gestational age. Results: The differences of urinary S100B protein were statistical significance between the different gestations. The levels of urinary S100B protein were higher in preterm infants, whose gestations were lower than 32 W, than those of other groups. The levels of S100B protein were significantly higher in samples of 27 peri-intraventricular hemorrhage (PIVH) and 3 peri-ventricular leukomalacia(PVL) than those in samples without brain damage( P ＜ 0.05). The S100B levels were significantly higher in urine of 10 preterm infants with polycethemia than those in infants without brain damages. In addition, the S100B levels were different in urine of preterm infants with different prognosis. The S100B levels were significantly higher in urine of infants who died or deteriorated than those of others(P ＜ 0.05). Conclusion: There is an evident trend of decrease in urinary S100B protein concentration with increasing gestational age. It will be helpful to identify preterm infants with PIVH,PVL and high risk of brain damages by measurement of S100B protein in urine early after birth, which indicates further inspection, provides protective treatment and enhances follow up.
ABSTRACT
Objectives: To study the value of glutamine dipeptide supplemented lower caloric parenteral nutrition in elder abdominal surgical patients. Methods:Forty patients were randomly allocated into study group and control group, receiving isocaloric (83.6 kJ/kg?d -1 ) and isonitrogenous (0.16 g/kg?d -1 ) PN from post operation day1 to post operation day 6. The study group received 0.3 g of alanyl glutamine/(kg?d)? Plasma albumin, pre albumin, IgG, IgA and IgM level were measured and lymphocyte was counted before surgery and on days 1 and 7 after surgery. Nitrogen balances were calculated postoperatively on day 1, 4 and 7. Results:Compared with preoperation, plasma albumin and pre albumin levels were both decreased in two groups and was markedly decreased in the control group ( P
ABSTRACT
Objective To observe some current dilemmas in the treatment of extremely preterm infants and to explore the method to solve the problems.Methods To analyze the problems with Bioethics.Results To advance some methods for solving the bioethical problems associated with medical staffs,parents,and the society.Conclusions Medical staffs should keep studying professional knowledge,understand the advances in the treatment of extremely preterm infants,improve the ability and skills to inform parents,diagnose and treat according to related guidelines,respect the rights and decision of the parents,and provide scientific guidance.The parents should be actively involved in medical activities and informed the rights,responsibilities in the treatment of their infants.Society should also take into consideration the interests of this special group in the field of insurance with the development of economy.
