Some immunosuppressants influence the synthesis and metabolism of lipids,which is a major factor for hyperlipidemia in organ transplant patients.The recent studies on the relationship between immunosuppressants and hyperlipidemia are reviewed.

Central nervous system ( CNS) injuries, such as cerebral ischemia, traumatic brain injury (TBI), and spinal cord injury (SCI), are often accompanied by complex pathological changes, and could lead to a variety of other neurological diseases.Neurons and glial cells are precisely regulated by many genes.MicroRNA ( miRNA ) are endogenous molecules discovered in recent years that regulate post transcriptional gene expression.They are highly expressed in the central nervous system and abnormal expressed under pathological conditions.They are involved in regulating variety of pathological processes after CNS injuries, and are CNS disease potential biomarkers.

Objectives: To evaluate the clinical application of emergency extracorporeal circulation(ECC) in cardiac surgery. Methods: Emergency open heart surgery was performed in 24 ECC cases. Warm blood left heart bypass was performed in 3, hypothermic cardiopulmonary bypass in 21. The vena cava-aorta extracorporeal circulation was built in 16,vena cava-femoral in 4, left atrium-femoral in 3 and femoro-femoral in 1. Retrograde or antegrade perfusion through aortic root were applied to protect the heart. Results: There were 2 hospital deaths, the hospital mortality rate was 8.3%. The cardiopulmonary bypass was established in 10 to 15 minutes with an average duration of cardiopulmonary bypass of 78～132 minutes. Twenty-two patients were discharged from the hospital and have resumed a normal and active life style. Conclusions: Emergency cardiopulmonary bypass support is a powerful resuscitative tool that may stabilize the condition of patients with cardiogenic shock and mutiorgan dysfunction to allow for definitive intervention. The femoro-femoral cannulation is the first choice for emergency. The time to establish extracorporeal circulation should be as short as possible.

Aim This paper aims at investigating the effect of dofetilide on Na+/Ca 2+exchange in ventricular myocytes of adult guinea pigs. Methods Rapid enzymatic isolation procedure was performed to get single ventricular myocytes from adult guinea pigs. After the whole cell configuration was formed, a ramp voltage-clamp pulse depolarized from a holding potential of -40 mV to +60 mV, then hyperpolarized to -120 mV at a rate of 90 mV/s to record the Na+/Ca 2+ exchange current (I Na/Ca) and the influence of dofetilide from 0.03～1.0 ?mol?L -1. Result Dofetilide from 0.03～1.0 ?mol?L -1 concentration-dependently increased the I Na/Ca in both outward and inward mode. The EC 50 of dofetilide on I Na/Ca in outward and inward mode of NCE was 0.178 ?mol?L -1 (95% confidence interval was 0.040～0.787 ?mol?L -1) and 0.178 ?mol?L -1 (95% confidence interval was 0.038～0.842 ?mol?L -1), respectively. Conclusion Dofetilide concentration-dependently increased the outward and inward Na+/Ca 2+ exchange current in ventricular myocytes of adult guinea pigs.

Objective To investigate altered levels and clinical significance of serum miR-133a in patients with acute coronary syndrome ( ACS ) and stable coronary artery disease ( SCAD ) .Methods Retrospective study.Serum miR-133a levels were determined by TaqMan quantitative reverse-transcription PCR assay in 64 ACS, 62 SCAD patients who were admitted to Jinling Hospital from October 2011 to October 2012 and 70 normal controls who had contemporaneously visited Jinling Hospital for routine examination .The ACS and SCAD patients were diagnosed according to the European Society of Cardiology guidelines .Serum lipid/lipoprotein profiles , myonecrosis biomarkers and Gensini scores were also analyzed .The area under curve ( AUC) and 95%confidence interval ( CI) were calculated using ROC analyses .The odds ratio ( OR) and 95%CI were calculated using the multivariate logistic regression analyses .Results Compared with the controls [ΔCt:1.00 ±0.05], serum miR-133a levels were significantly increased in both ACS [ΔCt:2.34 ±0.24] (t=6.059, P<0.001) and SCAD [ΔCt:1.45 ±0.13] (t=3.265, P=0.001) patients.The miR-133a levels in ACS patients were significantly higher than in SCAD patients (t=3.133, P=0.002). Serum miR-133a were positively correlated with levels of creatine kinase MB ( CK-MB) ( r=0.402, P<0.001), cardiac troponin I (cTNI) (r=0.410, P=0.001) and Gensini scores (r=0.438, P<0.001). ROC curve analyses showed that the AUC of miR-133a for differentiating coronary artery disease (CAD) and controls was 0.717 (95%CI:0.645-0.788, P<0.001) and the AUC for differentiating ACS and SCAD was 0.667 (95% CI:0.573-0.761, P=0.001).Logistic regression analyses revealed that high miR-133a levels were closely associated with the presence of ACS ( OR=6.00, 95% CI:1.93 -18.67, P=0.002) and SCAD (OR=2.81, 95%CI:1.03-7.68, P=0.044), and also had statistical significance for differentiating ACS and SCAD (OR=2.13, 95% CI:1.20-3.78, P=0.010), after adjustment for the age, gender and serum lipid/lipoprotein levels.Conclusions Serum miR-133a levels were significantly elevated in CAD patients, and ACS patients exhibited the more significant increase .Serum miR-133a may be function as the potential biomarker for the disease assessment and judgement .

Aim To explore the potential mechanism of ulinastatin’s antioxidant effect by examining the Nrf2 /HO-1 pathway.Methods OVA-induced asthma of mice was cured by intraperitoneal injection of ulinas-tatin (1 00 kU·kg -1 ·d -1 ).Control mice were given the same volume of PBS (pH 7.4).To investigate the effect of ulinastatin on airway hyperresponsiveness, levels of interleukin IL-4,IFN-γand OVA specific IgE in bronchoalveolar lavage fluid (BALF)were measured using enzyme-linked immunosorbent assays (ELISAs). The content of ROS from BALF of mice was tested in double hydrogen rhodamine (DHR)-1 23 method.The level of protein carbonyl and MDA from lung tissue of mice was detected with Protein carbonyl content assay kit and MDA kit.And antioxidative enzyme in mice BALF was tested by antioxidant enzyme kit.The levels of HO-1 in lung tissue from mice were detected by Western blot and Real-time PCR.Nuclear transfer and binding activity of Nrf2 were tested respectively by Western blot,IF and EMSA.Results Ulinastatin could alleviate the airway hyperresponsiveness,dis-tinctly reduce the content of IL-4,OVA specific IgE, ROS,protein carbonyl and MDA,but upraise the ex-pression of IFN-γand antioxidative enzyme such as SOD,GSH and TAOC. Moreover, the antioxidant effect of ulinastatin could be reversed by Znpp,which was the inhibitor of HO-1 .Ulinastatin could obviously induce the expression of HO-1 in protein level in a dose-and time-dependent manner.Ulinastatin could also induce the nuclear transfer of Nrf2 and increase the binding activity of Nrf2 as well as the expression of HO-1 in gene level;Conclusion Ulinastatin could induce the activation of Nrf2 /HO-1 pathway,which may contribute to the protective effects of ulinastatin a-gainst OVA-induced oxidative stress.

Objective To evaluate the influence of the CT enterography (CTE) in different scan phases of small intesti?nal wall and arteriovenous vessels, and to confirm the diagnostic efficiency thereof. Methods A total of 286 patients under?went CTE were collected, and their CT image of three scan phases, including 20 s, 40 s and 60 s after injection, were record?ed. Values of reinforcement of the intestinal wall and arteriovenous enhancing degree in all phases were collected. A statisti?cal analysis was used to confirm the best phase for showing the structure. The diagnostic efficiency of the best phase of CT image was evaluated for the clinical diagnosis of small intestine and vascular lesions. Results (1) The CT value of the small intestinal wall in the intestinal phase was significantly higher than other two phases (P<0.05). There was no significant dif?ference in CT value between arterial phase and portal phase. (2) Comparison between three phases of CT values of ileum showed that artery:arterial phase>intestinal phase, and there is no statistical difference between the intestinal phase and oth?er two phases. The result of CT value of ileum vein showed that intestinal phase>portal phase>arterial phase (P<0.05). (3) The sensitivity was 95.8%, the specificity was 94.9%, the accuracy was 95.1%, the positive predictive value was 79.3%and the negative predictive value was 99.1%using CT image of intestinal period for diagnosing small intestinal diseases. (4) The intestinal period showed small intestinal lesions and confirmed by pathology including 22 cases of small intestinal lympho?ma, 10 cases of stromal tumor, 1 case adenoma, cavernous 3 cases hemangioma and 8 cases of Crohn's disease. The diagno?sis of hemangioma should be combined with arterial phase. Conclusion Small intestinal wall and blood vessels have better display performance in the intestinal phase of multiphase CT enterography, using the arterial phase and intestinal phase scan?ning, we can make an accurate diagnosis for the majority of small intestinal diseases.
