[Objective] The purpose is to determine the effect of Chaihu Plus Longgumuli Decoction(CD)on behaviors and plasma adrenocorticotropic hormone(ACTH)level changed by psychological stress in rats.[Methods] Male Sprague-Dawley rats were randomly allocated to four groups as follows:normal(C),psychological stress model(P),CD(12.5g/kg,ig)+P(DP),and CD(25g/kg,ig)+P(HP).One week later,rats were subjected to psychological stress.The behaviors of rats were tested in open field conditions,and the plasma ACTH level was detected by radioimmunoassay.[Results] The crossing scores,the rearing cores and plasma ACTH level increased more significantly in the psychological stress model rats than that in normal group;Rats in both DP and HP groups showed lower crossing and rearing cores and blunted elevation of plasma ACTH after psychological stress compared with rats in psychological stress model.[Conclusion] The hypothalamo-pituitary-adrenocortical(HPA)axis function and anxiety-like behavior could be regulated by CD during psychological stress in rats.

Objective:To determine levels of insulin and glucose of maternal serum (MS),umbilical venous serum (UVS) and umbilical artery serum (UAS) in normal term pregnancy and intrauterine growth retardation(IUGR).Methods:One hundred and seven cases of normal gestational weeks on induction of labors and spontaneous deliveries and 32 cases of pregnancies complicated with IUGR.Levels of insulin were measured with sensitive radioimmunoassay and levels of glucose were measured by the glucose oxidase-peroxidase method.Results:Level of insulin of maternal serum was not significantly different before 28 gastational weeks and peaked on 28 th gastational week,then it decreased with gestational weeks and peaked again at last term.Levels of insulin increased in UVS and UAS.Levels of glucose in MS,umbilical venous serum and umbilical artery serum were not significantly different.Level of insulin and glucose of MS in IUGR had no change,but it was significantly different in IUGR of UVS and UAS (P<0.01).Conclusion:Our study suggested a decrease of insulin and glucose in UVS and UAS with IUGR.

Objective To understand the distribution situation of respiratory viral infection among adult inpatients with respiratory infection in the emergency department.Methods The detection results data of 5 kinds of viruses RSV,IVA,IVB,PIV1,PIV2,PIV3 and ADV by indirect immune fluorescence assay in 384 adults patients with respiratory infection in the emergency department of our hospital from January 2014 to December 2015 were collected.The epidemic characteristics of different viruses were analyzed.Results Among 384 specimens,208 cases were positive in respiratory virus IgM antibody,the viral infection positive rate was 54.17%.The mixed virus infection and influenza B virus infection were most common,their viral positive rates were 26.56% and 23.44% respectively,In the mixed viral infection,the positive rate of IVA + IVB mixed infection was highest,accounting for 87.25%,which was higher than that of other kinds of mixed viral infection.The viral infection positive rate had no statistical difference between different genders(P>0.05).The viral infection rate was higher in autumn and winter,which were 66.06% and 68.37% respectively and higher than 42.31% and 34.25% in spring and summer,the difference was statistically significant(P<0.05).The viral infection rates of youth (18-45 years old) and middle-aged (>45-60 years old) were 64.94% and 63.86% respectively,which were higher than 48.45%,44.92% and 55.56% in pre-elderly (>60-75 years old),elderly (>75-90 years old) and longevous elderly (>90 years old),the differences were statistically significant(P<0.05).Conclusion The respiratory virus mixed infection and IVB infection are most common in the emergency wards,moreover the viral infection situation shows the seasonal and age characteristics,but which is not affected by sex factor.
