Objective To observe the serum estradiol level in newborns at different gestational age and the infants with retinopathy of prematurity (ROP), and explore the relationship between these changes and ROP. Methods A total of 178 newborns hospitalized in the Children's Hospital of Fudan University were enrolled in the study. They were divided into three groups based on the gestational age, ＜ 32 weeks group, 32-37 weeks group and term group. The three groups were further divided into non-oxygen and oxygen subgroups. Infants with birth weight less than 2000 g were evaluated for ROP and those diagnosed as ROP were under ROP group (n=6). Serum estradiol levels were measured every week from birth to discharge with radioimmunoassay. Results Serum estradiol levels of newborns quickly declined after birth. In the non-oxygen subgroups, serum estradiol levels in 32 ～ 37 weeks group were remarkably higher than those of term group in the first week [(3506±1376) pmol/L vs (1717±179) pmol/L,P＜0. 05] and the third week [(1431±92) pmol/L vs (996±102) pmol/L, P＜0. 05]; Serum estradiol levels in ＜32 weeks group was only remarkably higher than those of term group in the first week [(3173± 1369) pmol/L vs (1717± 179) pmol/L,P＜0. 05]; Serum estradiol level in the ＜32 week group was (560±355) pmol/L, lower than that in the 32-37 weeks group [( 1124 ± 128) pmol/L] (P＜0. 05). There was no difference of serum estradiol levels in the oxygen and non-oxygen subgroups of the same group. There was no significant difference of serum estradiol levels between the ROP group and ＜32 weeks group. Serum estradiol levels in ROP group was lower than that of premature group without ROP at 29 and 32-36 weeks of corrected gestational age, but no statistical difference was shown. Conclusions Very low serum estradiol level in premature infants may be related to the development of ROP, but further clinical studies are required.

Military hygiene is one of compulsory courses for undergraduates majored in clinical medicine in military colleges. Aiming at the disconnection between theoretical and practical ability in the traditional teaching process and combining with professional features of military hygiene, teaching reform should give priority to curriculum standards, human resource construction, teaching content and method, teaching quality assessment and feedback system. Meanwhile, teaching idea of‘learning to use’ should be strengthened and teaching scheme in line with the actual needs of military health service security work should be put forward in order to provide new ideas for training military health personnel.

Objective To investigate the relationship between the serum high sensitive c-reactive protein (hs-CRP) and prealbumin (PAB) and the acute heart failure during the early stage of acute myocardial infarction (MI) patients.Methods A total of 181 MI patients (male:n =154,85.1％ vs.female:n =27,14.9％),admitted between Seppember 2010 and September 2012,were enrolled.They were divided into heart failure group (n =114,63.0％) with Killip classification recorded and control group (n =67,37.0％) without heart failure.The levels of serum hs-CRP and PAB were determined from the venous blood in the followed morning after admission.The clinical data were analyzed by logistic regression,Spearman correlation,and ROC curve.Results The serum level of hs-CRP (mg/L) in the heart failure group was significantly higher than that in the control group (P =0.000),while the serum level of PAB (mg/L) in the heart failure group was significantly lower than that in the control group (P =0.000).High level of hs-CRP and low level of PAB were significantly correlated with Killip classification (rhs-CRP =0.234,Phs-CRP =0.003 ; rPAB =-0.321,PPAB =0.000).Serum hs-CRP (P =0.023,OR 1.086,95％ Cl 1.012-1.167) and PAB (P =0.038,OR O.991,95％ CI O.983-0.999) were the independent risk biomarkers of acute heart failure subsequent to myocardial infarction determined by multivariate logistic regression analysis.The area under the ROC curve:AUChs-CRP =0.722,95％ CI 0.651-0.786; AUCPAB =0.723,95％ CI 0.652-0.787.Conclusions With high level of serum hs-CRP or low level of serum PAB during the early stage of acute myocardial infarction,patients were predisposed to the development of acute heart failure consequently.Both of them are the independent risk biomarkers of acute heart failure subsequent to myocardial infarction.Furthermore,they were significantly correlated with severity of the heart failure in terms of Killip classification.

BACKGROUND:A cross-emulsification patented product of microporous polysaccharide hemostatic powder was prepared using potatoes as raw material with independent intel ectual property rights.
OBJECTIVE:To observe hemostasis effects of microporous polysaccharide hemostatic powder on soft tissue trauma.
METHODS:A wound, about 3 cm long and 0.5 cm deep, was made on the abdominal soft tissue of rabbits in the experimental group 1, and then microporous polysaccharide hemostatic powder, 1.0-2.0 g, was sprayed directly on the wound. In the experimental group 2, a wound, about 3.0 cm long and 1.0 cm deep, was made on the abdominal soft tissue of rabbits, and then microporous polysaccharide hemostatic powder, 1.0-2.0 g, was sprayed directly on the wound. Another rabbits with untreated wound served as controls.
RESULTS AND CONCLUSION:Microporous polysaccharide hemostatic powder formed a“pasty gel”covering the bleeding wound that achieved hemostatic effect. The bleeding time was (15.25±1.04) seconds in the experimental group 1 and (11.25±1.89) seconds in the experimental group 2. The marked effective and effective rates for hemostasis were 87.5%and 100%, respectively. In the control group, the bleeding time was more than 5 minutes. Hematoxylin-eosin staining showed mild muscle edema, vasodilatation of smal blood vessels, and few scattered endoplasmic neutrophils infiltrated at 24 hours after treatment with microporous polysaccharide hemostatic powder;til the 7th day, inflammation subsided, mild fibrosis was visible on muscle tissue surface, the hemostatic powder was completely absorbed, the wound tissue was close to the normal tissue, and there were no significant changes in muscle cells. These findings suggest that microporous polysaccharide hemostatic powder can be used for hemostasis of soft tissue trauma.
