BACKGROUNDA number of studies have demonstrated the rates of overall and aneurysm-related mortality and morbidity in Western populations. The cardiovascular risk factors influencing postoperative outcome have been also reported. Until recently, little has been known about the prognosis in this patient cohort in the Chinese population. We evaluated the independent predictors of mortality and morbidity in abdominal aortic aneurysm (AAA) patients undergoing elective surgical treatment and emphasized whether the coronary artery revascularization could have any effect on the overall mortality and morbidity in patients following the current guideline recommendation.
METHODSA total of 386 patients (174 women) undergoing surgery in Beijing Anzhen Hospital from January 2008 to June 2010 were enrolled (mean age (70.6±10.5) years). Kaplan-Meier curves were constructed to compare the mortality and morbidity of AAA patients with coronary artery revascularization and those without. A Cox proportional hazards model was constructed to identify clinical factors associated with two-year outcomes. The primary outcomes were death from any cause, the pre-specified morbidity was re-hospitalization for pulmonary conditions, congestive heart failure, angina, ischemic/hemorrhagic stroke.
RESULTSDuring the two-year follow-up, 34 patients died and 65 experienced re-hospitalization with pulmonary conditions, congestive heart failure, angina, or ischemic/hemorrhagic stroke. Kaplan-Meier survival analysis showed that the AAA patients with cardiac revascularization had no higher incidence of overall mortality and major morbidity than those without (log-rank test P = 0.35 and P = 0.40, respectively). Cox proportional hazards regression analysis showed that level of lowdensity lipoprotein (HR, 4.06; 95% CI: 1.19-18.7, P = 0.027) and AAA size (HR, 2.18; 95% CI: 1.28-11.65, P = 0.036) were independently associated with the incidence of overall mortality. Long-term use of angiotensin converting enzyme inhibitors, statins, AAA size and systolic blood pressure were independent predictors of the secondary pre-specified outcomes.
CONCLUSIONSCoronary artery revascularization following the guideline recommendations did not increase the mortality and morbidity of Chinese with AAA who were undergoing repair. Absence of angiotensin converting enzyme inhibitors and statins, AAA size, and systolic blood pressure were powerful predictors of the clinical events.

A 10-month-old boy suspected of genetic abnormality was admitted for fever and coughing. Routine G-banding chromosome analysis of the peripheral blood lymphocytes and hereditary pattern analysis on the basis of the karyotypes and disease history revealed that the karyotype of the boy's mother was 46, XX,t(4;9)(q31;p24), and that of the boy was XY,der(9)t(4;9)(q31;p24)mat. The mother was identified as a carrier of balanced translocation of the chromosome who gave the abnormal chromosome 9 to her son, and she had only a chance of 1:18 to have a normal offspring. This case reiterates the importance of antemarital examination and prenatal diagnosis for preventing chromosomal diseases.

To evaluate the therapeutic effect of hematopoietic stem cell transplantation (HSCT), we performed HSCT in 30 patients with hematologic maligancies. Of the 30 patients, 10 underwent autologous peripheral blood stem cell transplantation (auto-PBSCT), 13 underwent myeloablative allogeneic HSCT while 7 underwent nonmyeloablative allogeneic HSCT, which were designated as autologous group, myeloablative group and nonmyeloablative group, respectively. All patients except the one who underwent cord blood transplantation, were successfully engrafted. Median time for the granulocytes > or = 0.5 x 10(9)/L and platelets > or = 20 x 10(9)/L were 12 days and 13 days respectively in autologous group, 16 days and 19 days in myeloablative group, 15 days and 12 days in nonmyeloablative group. In myeloablative group, acute graft-versus-host diseases (aGVHD) was observed in 3 patients, all of which were I-II grade. Oral mucous cGVHD was observed in 1 patient. In nonmyeloablative group, 1 patient developed intestinal aGVHD grade IV and cutaneous cGVHD was induced by donor lymphocyte infusions (DLI) in 3 patients. 1 patient had hematological relapse in autologous group. 1 patient had cytogenetic relapse in myeloablative group. In nonmyeloablative group 3 patients had cytogenetic relapse and were cured by DLI, 1 patient had hematological relapse. 4 of the 30 patients died of infection (2 patients), grade IV aGVHD (1) and relapse (1) respectively. 26 patients are still alive. 3 years overall survival (OS) and 3 years disease free survival (DFS) were 100% and 64.81% respectively in autologous group, 78.75% and 63% respectively in myeloablative group while both 66.67% in nonmyeloablative group. In conclusion, autologous group had less transplant-related complications and mortality. Active prophylaxis of relapse could significantly promote DFS. The transplant-related mortality limited DFS in myeloablative group. More relapses occurred in nonmyeloablative group, but could be cured by DLI.

To explore the molecular mechanisms of sodium butyrate working on SKM-1 cell proliferation/differentiation and to study its synergistic effect with all-trans retinoic acid (ATRA), SKM-1 cells were grown in the absence or presence of sodium butyrate and/or ATRA. The percentage of viable cells was determined by trypan blue exclusion. Differentiation was determined by nitroblue tetrazolium (NBT) reduction and cell surface adhesion molecules was analyzed by FACS. Cell cycle distribution was examined after DNA staining by propidium iodide. D-type cyclins, cdks and P21 mRNA were studied by reverse transcription-polymerase chain reaction. Our results showed that sodiun butyrate and/or ATRA blocked cells mainly in the G0/G1 phase of the cell cycle. ATRA inhibited the mRNA expression of CDK6, CDK4, cyclinD3 and cyclinD1. Sodium butyrate inhibited the mRNA expression of CDK2, cyclinD2 and cyclinD1. ATRA and sodium butyrate inhibited the mRNA expression of CDK6, CDK4, CDK2, cyclinD1, cyclinD2 and cyclinD3. Both ATRA and/or sodium butyrate stimulated p21 expression at the mRNA levels. Our results suggest that the effect of sodium butyrate on cell proliferation/differentiation might be linked to its ability to induce expression of p21 mRNA and inhibit the cyclin-cdk complexes. Our observations support the notion that the sodium butyrate works synergistically with ATRA.
