Objective To discuss clinical features and harmfulness of acid-base imbalance in newborn by investigating the changes in blood gas of cord and artery blood,and to establish more appropriate prevention measures. Methods One hundred and ninety-two cord blood and 113 peripheral artery blood of neonates were measured for blood gas analysis by automatic blood gas analysis instrument from America;meanwhile,the concentrations of K~+,Na~+ and Cl~- were detected by biochemical analyzer.Results Among 192 neonates,179 were normal labor and 13 neonates underwent acidosis of different degrees.The incidence was 79.9%.Among the 13 ca-(ses),2 cases had severe asphyxia and both of them got serious mixed acidosis.For all the neonates, 156 cases got acidosis, 84 neonates underwent respiratory acidosis (43.8%), 47 cases with metabolic acidosis (24.5%) and 25 cases with mixed acidosis (13.0%).The left 113 neonates were abnormal labor.Among them,99 cases had acid-base disturbance of different degrees (87.6%). Among the 99 acid-base disturbance cases, 50 cases were single metabolic acidosis (44.2%) and presented the most common changes; the second was single respiratory acidosis, totally 20 cases (17.7%).The third was metabolic acidosis combined with respiratory alkalosis, totally 16 neonates (14.2%).Eleven cases had mixed acidosis (9.7%) and 2 cases were respiratory alkalosis combined with metabolic alkalosis (1.8%).Conclusions While the normal labor neonates still got acidosis of different degrees,the acid-base imbalance of abnormal labor is much more prominent,and the critical neonates often got mixed acid-base imbalance.Serious acid-base imbalance can cause fatal pathological changes in body.The dangers of acidosis and alkalosis can not ignore either. The condition of acid-base imbalance can be judged more accurately by the combination of blood gas analysis and anion gap.The perinatal health cares are important measures to prevent acid-base imbalance.

OBJECTIVE:To establish the identification method of Rhizoma Arisaematis and content determination of flavon-oids.METHODS:TLC was used to identify Rhizoma Arisaematis with schaftoside and ischaftoside as reference substances.The content of flavonoids was determined by HPLC.RESULTS:TLC of test sample and that of control substance had same color dots.The linear range of schaftoside and isoschaftoside were 7.925～126.8 ?g?mL-1(r=0.999 9) and 3.996～63.94 ?g?mL-1(r=0.999 7) respectively.Average recoveries were 99.4% for schaftoside (RSD=2.10%,n=9) and 99.52% for isoschaftoside(RSD=2.42%,n=9).CONCLUSION:The method is simple,accurate and reproducible for the quality evaluation of Rhizoma Arisaematis.

Objective To study the protective effect of a hyperoxic solution on phosgene-induced lung injury by observing the changes in W/D ratio, lung water (LW), and L/B, and MDA contents, GSH-PX activity, and protein contents in broncho-alveolar lavage fluid (BALF). Methods The rabbits were divided into normal control group, hyperoxic solution (HO) and balance salt(BS) groups.Group HO and Group BS inhaled phosgene, and hyperoxic solution was given intravenously in group HO, but BS was given in group BS. W/D, LW, L/B, and MDA contents,GSH-PX activity,protein contents in broncho-alveolar lavage fluid (BALF) were determined. Results The MDA contents, W/D, LW and L/B were increased, and GSH-PX activity was decreased significantly in Group HO and Group BS compared with control group (P
