Objective To explore the conditions, safety and efifcacy of exchange transfusion for extremely severe hyper-bilirubinemia in term newborns requiring mechanical ventilation. Methods Ten full-term newborns of extremely severe hyper-bilirubinemia requiring mechanical ventilation were selected from January 2010 to March 2013 in the department of neonatology. After stable vital sign was achieved by the use of conventional life support, peripheral arterial and venous synchronous exchange transfusion was performed. The bilirubin, platelets, blood calcium, blood coagulation and blood gas were monitored before and after exchange transfusion. The effects and adverse events of exchange transfusion in newborns on mechanical ventilation were observed. Results There was no death in the study, and the replacement rate of total bilirubin was 50.5%. The main adverse event was thrombocytopenia (80%). There was a signiifcant difference in platelet counting before and after exchange transfusion (P<0.05). There was no signiifcant difference in blood coagulation, pH/HCO3-of the blood gas, prothrombin time (PT) and acti-vated partial thromboplastin time (APTT) before and after exchange transfusion. Conclusions It is relatively safe to implement an exchange transfusion in the full-term newborns with severe hyperbilirubinemia in newborns requiring mechanical ventilation, but the use of conventional life support is prerequisite because it stabilizes vital signs. The relatively ideal replacement rate of bili-rubin and the low incidence of adverse reactions are expected. However long-term prognosis of neural system is still unknown.

OBJECTIVE:To study the genetic diversity of germplasm resources of Duchesnea indica from Hunan. METHODS:The random amplified polymorphic DNA(RAPD)reaction system of germplasm resources was established and RAPD-PCR was ad-opted to detect the expressions of 24 groups of D. indica from Hunan(including 21 wild and 3 cultivated varietos in different geo-graphical distribution). Agarose gel electrophoresis was used to analyze the results and calculate allele number (Na),effective al-lele number (Ne) the polymorphism points percentage (PPB),Nei’s gene diversity index (H) and Shannon’s information index (I). RESULTS:Totally 14 polymorphic primers were screened and 90 electrophoresis bands were amplified,including 81 polymor-phic bands with Na of 1.900 0,Ne of 1.540 1,PPB of 90.0%,H of 0.312 8 and I of 0.467 5. CONCLUSIONS:The genetic diver-sity of D. indica from Hunan is rich,and there were differences in genetic background between the cultivated species and wild spe-cies;clustering results show significant correlation with geographic distribution.

Objective To study the distribution of surfactant protein A2 (SP-A2) haplotype and its association with preterm respiratory distress syndrome (RDS) susceptibility in a local Chinese cohort.Methods Using population base and case-control study cohorts,genotyping for four single nucleotide polymorphism (SNP) was performed,rs1059046,rs17886395,rs1965707,rs1965708,in 80 term infants,50 preterm infants with RDS (RDS group) and 50 preterm infants without RDS(control group) by using TaqMan (R) real-time polymerase chain reaction.Infants in RDS group and control group were matched according to gender and gestational age.Frequency of each haplotype was compared between preterm infants with RDS and without RDS,term infants and preterm infants without RDS.Results Most common haplotypes in term infants were 1A0,1A5,1A1.In each preterm infants groups with RDS and without RDS,1A0,1 A5,1 A1 were also the most common haplotypes.Among these three common haplotypes,frequency of 1A0 was lower in preterm infants,including RDS group and control group,than that in term infants.No significant difference was found between preterm groups with RDS and without RDS (P ＞ 0.05),neither in preterm infants with gestational age ≥32 or ＜ 32 weeks.Haplotype 1A0 frequency(0.542) in term infants was significantly higher than that in preterm infants ＜ 32 weeks without RDS (0.329) (x2 =6.06,P =0.01).Conclusions SP-A2 haplotype distribution in a local Chinese population shows ethnic characteristics to some extent.Only SP-A2 does not contribute to the susceptibility for preterm RDS.
