Objective The incidence of post-operative hyperbilimbinemia, which is associated with poor outcomes in patients, was reported to be increased in recent years though it has been a rare complication for cardiac operations. Post-opera-tive impairment of liver function is highlighted. We evaluated the incidence and prognosis of post-operative hyperbiliruhinemia in adult patients who underwent cardiotomy with extracorporeal membrane oxygenation (ECMO) support. Methods Sixty-five adult patients who had received ECMO support after cardiac surgery from 2004 to 2008 were enrolled and evaluated retrospec-tively. Post-oporative hypethilirubinemia was defined as the serum level of the total bilirubin more than 51.3 μmol/L during postoperative period. Demographic and clinical data included gender, age, types of surgery, perioperative hemodynamic param-eters, biochemical variables, duration of the ventilation support, ICU stay and outcomes. Results The mean age of the pa-tients was (50.1 ± 13.9) years, forty-six patients(70.8%) were male. The main cardiac procedures were heart transplanta-tion for 9 patients, coronary artery bypass grafting and/or valve operations for 47 patients, congenital heart disease correction for 4 patients and other operations for 5 patients. Among all patients, fifty-one patients(78.5%) were weaned from ECMO succeas-fully and thirty-thrce patients were discharged from hospital. The overall mortality rate was 49.2%. Overall incidence of post-operative hyperbilirubinemia was 55.4%. In patients with postoperative hyperbilirubinemia, the mean peak value for serum to-tal bilirubin was 104.8 (68.5-156.7) μmol/l. The hospital mortality in the hyperbilirubinemia group was significantly higher than that in the non-hyperbilirubinemia group(66.7% vs. 27.6%, P <0.01). Moreover, postoperative hypethilirubinemia (adds ratio = 3. 895, 95% confidence interval, 1.088 - 13.947 ; P = 0.037) and SOFA score (odds ratio = 1.214, 95% confidence interval, 0.987 - 1.494, P = 0.047) and APACHE Ⅲ score (odds ratio = 1.096, 95% confidence interval, 1.028 - 1.169 ; P = 0.004) were associated with hospital mortality after adjusting for preoperative levels of the total bilirubin, direct bilirubin, gender and age. Conclusion Postoperative hyperbilirubinemia is one of the complications in adult patients who undergo cardiotomy with ECMO support, and is associated with increased hospital mortality.

Objective Toll-like receptor ( TLR) gene family is the most important pathogen recognition receptor and animal experiment have found TLR4 mice is inclined to infect aspergillosis ( IA) .The study was to investigate the variation of TLR4 gene in Chinese Han nationality and its relation with the susceptibility of IA. Methods 25 patients diagnosed with proven IA from June 2011 to December 2012 in our hospital were enrolled, among which 17 were males.Their average age was 52.4 ±12.3, and 12 pa-tients had underlying diseases, the others had no underlying diseases.The control group consisted of 103 normal persons, among which 70 were males.Their average age was 56.0 ±17.2.All of the subjects were Chinese Han population.DNA was extracted from periph-eral blood.Polymerase chain reaction ( PCR) was applied to amplify the coding sequence of TLR4 gene followed by sequencing.The sequencing result was compared with TLR4 coding sequence in NCBI GenBank along with the analysis on amino acid change caused by genetic mutation and its effect on protein function.Comparison analysis was made on genetic mutation rate between IA group and con-trol group. Results Two missense mutations,TLR4 219 C>G and 1420 C>T, were identified in TLR4.The prediction result of protein structure showed 219 C>G resulted in the change of functional area for TLR4 to recognize pathogen and 1420 C>T caused no change in domains.The variation rate of TLR4 in IA group was 8%( 2/25 ) and both the patients had no underlying diseases. No mutation has been founded in control group and the difference between two groups was of statistical significance (P=0.037). Conclusion Two missense mutations (219 C>G and 1420 C>T) have been detec-ted in encoding area of TLR4 gene of IA patients.Variation in the cod-ing region of TLR4 gene may increase the susceptibility to IA.

Objective To explore the inhibitory effects of sulfated oligosaccharides PI-88 on the heparanase protein expression of human esophageal squamous cancer cell (ESCC) line TE-13, and to explore the effects of growth, angiogenesis and heparanase protein expression on ESCC xenografts of nude mice. Methods TE-13 cells were cultured and divided into three groups:group A (control group), group B (15 mg/L PI-88) and group C (30 mg/L PI-88). Heparanase protein expression of TE-13 cells was measured by Western blot assay after being cultured for 36 h. The ESCC suspension was injected subcutaneously in 10 BALB/c/nu mice to build up ESCC xenograft model. The model mice were divided randomly into observation group and control group (5 mice per group). The mice in observation group received 40 mg/(kg·d) PI-88. The mice in control group only received the same volume of saline at the same time. Both PI-88 and saline were daily administrated for 14 days. Every 2 days,the volume of xeongrafts were measured and the mice were executed at the 14th day. CD34 immunohistochemical staining was used to detect the micro vessel density (MVD) of xenografts. Western blot assay and immunohistochemical staining were used to detect the heparanase protein expression of xenografts. Results The heparanase protein expressions of TE-13 cells were significantly decreased in group B and group C than those of group A (P<0.001), with a kind of PI-88 dose-dependent manner. The volume, MVD and heparanase protein expression of xenografts were significantly lower in observation group than those of control group (P<0.05). Conclusion The heparanase protein expression in TE-13 cells can be inhibited by PI-88 in vitro and vivo. Furthermore, the growth and angiogenesis of ESCC xenografts were also inhibited by PI-88.
