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 evaluate the effect of homemade tirofiban in percutaneous coronary intervention for acute myocardial infarction. Methods Sixty four cases of consecutive acute myocardial infarction were enrolled and divided into two groups: the tirofiban group (n=34) and the control group (n=30). In addition to intravenous heparin, patients in the tirofiban group received a bolus dose of tirofiban (10 ?g/kg) before stenting and followed by a 0.15 ?g/(kg?min) infusion for up to 12-36 hours. The control group only receive routine intravenous heparin therapy before and during PCI. The post operation TIMI blood flow, bleeding events and major adverse cardiac events were observed in the 2 groups. Results A 97.1% of patients in the tirofiban group compared with 76.7% in the control group obtained TIMI grade 2-3 flow respectively. Among them, 91.2% in the tirofiban group but 70.0% in the control obtained TIMI 3 flow. There were no serious in-hospital bleeding complications and MACE. Conclusion Homemade tirofiban is effective in improving the TIMI grade and prognosis of acute myocardial infarction after PCI.

Objective To investigate the relation of inflammation markers to acute coronary syndrome and the clinical significance by observing the changes of P selectin、CRP 、IL 6、TNF ?、ICAM 1 during unstable agina pectoris and acute myocardial infarction(AMI). Methods 45 patients were selected as acute coronery syndrome(ACS)group, including 25 patients with unstable agina pectoris (UAP) and 20 patients with AMI; 25 patients as stable agina pectoris (SAP)and 20 persons as control group. The blood sample of the control group are drawn from venous in the morning, the agina pectoris group are drown from venous in the morning of the second day after hospitalized, however, the AMIgroup are drown from venous at the point of 6 hour、 12 hour、24 hour、48 hour、72 hour after episode. The concentration of CRP is determined by Scatter Turbidimetry , and the concentration of P selectin、IL 6 、TNF ?、ICAM 1 by ELISA. Results (1) SAP vs control ,the levels of P selectin、CRP 、IL 6、TNF ?、ICAM 1 all raise significantly ( P 0.05) ; (4) AMI vs SAP , the levels of P selectin、CRP 、IL 6、TNF ?、ICAM 1 all raise significantly ( P

Objective To investigate the influence of CD4+CD25+ regulatory T cells (Tregs) on the disease progression in MRL/lps mice. Methods Tregs were separated by using magnetic beads from splenic cells of MRL/lps mice and BALB/c mice, and concentrated. Twenty-four MRLAps mice were equally divided into 3 groups, test group 1 injected with Tregs from MRL/lps mice, test group 2 injected with Tregs from BALB/c mice, and control group injected with physiological sodium chloride solution. Three weeks later, the levels of urine protein as well as serum anti-dsDNA antibody were determined; subsequently, the mice were sacrificed followed by histopathological and immunopathological examination of renal tissue. Results A significant decline was observed in the test group 1 compared with the test group 2 and control group in the urine protein score (10.63 ± 4.17 vs. 20.00 ± 5.35 and 18.75 ± 8.34, both P < 0.05), serum anti-dsDNA antibody level (5.36 ± 2.40 pg/ml vs. 9.57 ± 1.97 pg/ml and 10.75 ± 3.98 pg/ml, both P < 0.05), glomerular sclerosis index [(32.00 ± 12.09)% vs. (45.50 ± 13.68)% and (47.50 ± 10.78)%, both P< 0.05], and immunofluorescence intensity of IgG immune complex in renal tissue (1.88 ± 0.99 vs. 2.88 ± 0.64 and 2.75 ± 0.71, both P< 0.05). No significant difference was noted in renal tubule interstitial impairment index between the 3 groups (4.63 ± 1.92, 6.00 ± 1.07 and 5.75 ± 1.28, all P> 0.05). There was no statistical difference between the test group 2 and control group in terms of any of the above parameters (all P > 0.05). Conclusions Injection of Tregs from homologous mice could significantly down-regulate proteinuria degree, serum anti-dsDNA antibody level, glomerular sclerosis index and IgG immune complex level in renal tissue, and thereby decelerate the progression of renal impairment in MRL/lps mice.

The successful establishment of animal models of cardiac arrest-cardiopulmonary resuscitation (CA-CPR) undoubtedly provided an important basis for exploring the method of cardiopulmonary resuscitation (CPR) and advanced cardiovascular life support (ACLS). However, pathophysiology varied with the etiology of cardiac arrest (CA). Therefore, preparation of similar animal models according to etiology was the basis for pathophysiological changes research. Compared with other animals, the rabbits had both the advantages of large and small animals, so they became common research object for the CA-CPR model. This paper reviewed the common methods of animal models of CA-CPR in rabbits. In this review, the methods, criteria, advantages, disadvantages and precautions of each model were analyzed, which would provide useful reference for CPR researchers.
