Objective To investigate the clinical features,etiology and related clinical factors in neonatal anemia.Methods Two hundreds and sixty four infants admitted to the Neonatal Intensive Care Unit between January 2009 to March 2012 were retrospectively analysed with different levels,different age,different gestational age.Results Among 264 patients,the occupancy of blood loss anemia was 54.5 ％.Mild and medium neonatal anemia were more than severe anemia (172 vs 92).Fetomaternal hemorrhage syndrome occurred commonly in severe anemia (16.3％,15/92).Early anemia was more than late anemia(182 vs 82).Hemorrhagic anemia in early anemia (64.3％,117/82)occurred mainly.Late anemia with infection mainly (67.1％,55/82).Fetomaternal hemorrhage syndrome were all early anemia and term to account for a higher proportion (94.4％,17/18);twin-to-twin transfusion syndrome occurred commonly among preterm term infants (96.7％,29/30).Conclusion Blood loss anemia was the main etiological factor resulting in neonatal anemia.The incidence of mild and medium neonatal anemia was quite high.Early anemia was more than late anemia.There might be some differences in the etiology between term and perterm infants.

Objective To explore the effect of enteral nutrition applied to bowel preparation of diabetes patients before electronic colonoscopy. Methods A total of 172 diabetes patients were randomly allocated to the experimental group and the control group with 86 patients in each group. The experimental groups executed no dietary restriction within 3 days before the examination, and received Ensure 1h before colonoscopy. However,the control group was given low residue diet within 3 days before the examination, and received no Ensure before colonoscopy. The enteral cleanness and incidence of hypoglycemic reaction, abdominal pain and horror was compared between the two groups. Results 72 cases(83.72%) of the experimental group and 70 cases (81.40%) of the control group had better enteral cleanness, and there was no statistical difference in intestinal cleanness between the two groups. In the experimental group the incidence of hypoglycemic reaction, abdominal pain, horror was significantly lower than those in the control group. Conclusions Bowel preparation with unrestricted diet and ingested ensure before colonoscopy can not only ensure intestinal cleanness but also enhance endurance of colonoscopy.

Objective To rapidly detect and identify pathogenic fungi of some deep fungal infections by PCR.Methods The suspensions of22pathogenic fungi(23strains)were amplified by PCR with fungal universal primers ITS86and ITS4which were labeled by FAM.The precise length of amplified fragments was determined by ABI PRISM TM 377Sequencer and Genescan analysis software,then compared with that of am-plicons of corresponding fungal DNA which were previously extracted.Results(1)Amplification of17pathogenic fungi with ITS4,ITS86resulted in a unique fragment length(except for A.nidulans and A.niger,C.albicans and C.stellatoidea,F.pedrosoi and E.dermatitidis).(2)No significant difference of the length of am-plicons was found between the fungal suspension and control organisms,based on the results of Genescan analysis.(3)The whole process took only6h to complete the detection.Conclusion The combination of fun-gal suspension PCR with ITS fungal universal primers and Genescan analysis might provide an accurate,spe-cific,sensitive,and rapid approach to detect and identify22pathogenic fungi causing deep fungal infections,and hold promise to be applied for the diagnosis of deep fungal infection.

Objective To observe the therapeutic effect of Qilin Xintongshu pill for treatment of patients with non-ST segment elevation acute coronary syndromes(NSTE-ACS)accompanied by gastrointestinal bleeding (GIB). Methods A prospective randomized controlled trial was conducted. A total of 67 hospitalized patients in Cardiovascular Department of Qionghai City Hospital of Traditional Chinese Medicine were divided into therapy group(35 cases)and control group(32 cases). Both groups were given conventional medical treatment(except anti-coagulative agent). In the therapy group,the patients received Qilin Xintongshu pill(the ingredients consisting of panax pseudo-ginsen,dragon's blood,immature orange fruit,etc.)oral administration,once 5 mg and 3 times a day,while in the control group,the patients accepted clopidogrel orally,once 75 g and once a day,the therapeutic course in both groups being 30 days. The major cardiovascular events(such as death,a newly-happened myocardial infarction(MI),MI secondary,obstinately ischemia)and incidence of massive hemorrhage of gastrointestinal tract were compared between the two groups,and the adverse events were observed. Results After treatment,the incidence of cardiovascular events and massive hemorrhage of gastrointestinal tract in the therapy group were decreased significantly compared to those in the control group 〔incidence of cardiovascular events:8.57%(3/35)vs. 28.13%(9/32), incidence of massive hemorrhage of gastrointestinal tract:2.86%(1/35)vs. 21.88%(7/32),both P<0.05〕. Adverse events were not observed in both groups,and the examinations of blood,urine,liver and renal functions were of no abnormalities before and after treatment. Conclusion Qilin Xintongshu pill can effectively reduce the incidences of cardiovascular events and massive hemorrhage of gastrointestinal tract in patients with NSTE-ACS accompanied by GIB in the therapeutic course of 30 days,therefore this traditional Chinese herbal medicine is an ideal agent for treatment of such disease.

AIM: To evaluate the different conditions inducing mouse embryonic stem cells (ESC) in vitro to differentiate into cardiomyocytes. METHODS: BRL conditioned medium was used to promote the growth of ESC and maintain them in an undifferentiated state. During the inducing process, retinoic acid (RA), DMSO, activin-A and TGF-? 1 were used as inducing reagents, and made up six kinds of differentiating medium. Then a three-step method inducing ESC cultured in hanging drops, in suspension and in plating was used to induce the differentiation of ESC. RESULTS: ESC were induced in vitro to differentiate into cardiomyocytes. Of all groups, the highest differentiating rate was observed in the group induced by activin-A (20 ?g/L) and TGF-? 1 (2 ?g/L). CONCLUSION: The inducing conditions including activin-A (20 ?g/L) and TGF-? 1 (2 ?g/L) is very valuable in inducing ESC differentiation into cardiomyocytes. [
