OBJECTIVETo analyze the factors which influence the safety and prognosis of aorta replacement combined with coronary artery bypass grafting (CABG) for thoracic aortic aneurysm associated with coronary artery disease.
METHODSFrom May 1982 to October 2002, 67 patients with thoracic aortic aneurysm were admitted, and 24 of them combined with CABG. Of the 24 patients, 9 received descending aorta replacement combined with CABG, and the other 15 received the ascending aorta replacement combined with CABG. The treatment results were compared with the other 43 patients only undergoing the thoracic aortic replacement.
RESULTSThe mortality rate of the patients with aorta replacement combined with CABG was 13% (3/24). Though the descending aorta replacement combined with CABG could make the cardiopulmonary bypass time and selective cerebral perfusion time longer, (278 +/- 54) min and (188 +/- 59) min respectively, no significant difference was observed in postoperative complications, 3-year survival rate, 3-year-cardiac-event-free rate compared with the patients only undergoing the thoracic aortic replacement (P > 0.05).
CONCLUSIONSThe aorta replacement combined with CABG can be performed safely, and the revascularization for coronary artery disease is useful for preventing occurrence of cardiac events.

OBJECTIVETo investigate the classification criterion and surgical treatment strategy of intrathoracic esophageal injury caused by foreign body.
METHODSEighty-four patients with intrathoracic esophageal injury caused by foreign body in our department from January 1980 to April 2004 were divided into 4 grade: grade I was non-penetrated injury of esophagus (18 cases); grade II was esophageal perforation with mild mediastinitis (39 cases); grade III was esophageal perforation with severe intrathoracic infection (17 cases); grade IV was aortoesophageal fistula (10 cases). Based on the degree of esophageal injury and the extension of inflammation, operative procedures were selected including esophagotomy, esophageal reparation, esophagectomy, mediastinal drainage, reparation of fistula and replacement of aorta.
RESULTSPatients in grade I and II were all cured . One death occurred in grade III (1/17), the same in Grade IV was 9 (9/10).
CONCLUSIONSClassification of esophageal injury caused by foreign body is helpful to the decision of surgical treatment strategy. The prevention of aortoesophageal fistula is the key point of reducing of mortality.

The purpose of this study was to investigate the efficacy of treatment with haploidentical donor's lymphocyte infusion(hiDLI) combined with interleukin-2 (IL-2) after transplantation of autologous peripheral blood stem cells mixed with haploidentical allogeneic bone marrow (mix-HSCT) for acute myeloid leukemia (AML). 49 patients diagnosed as AML were enrolled in this study. After preconditioning with TBI plus VEMAC regimen, all patients received mix-HSCT. Autologous peripheral blood hematopoietic stem cells were mobilized with chemotherapy-combined G-CSF, and haploidentical allogeneic bone marrow cells were not mobilized with G-CSF. 33 patients in test group were treated with hiDLI plus IL-2 for 1-8 times after hematopoietic reconstruction, 16 patients in control group received mix-HSCT only. All the patients were followed-up for more than 3 years. The results showed that all the patients obtained hematopoietic reconstruction, and no graft-versus-host disease (GVHD) was found. In two groups, the median time of absolute neutrophil count (ANC) ≥ 0.5×10(9)/L was 14 (12 - 18) and 14 (11 - 16) days, and WBC count ≥ 4.0×10(9)/L was 17 (16 - 22) and 18(17 - 20) days, Plt count ≥ 50×10(8)/L were 25 (24 - 29) and 25 (23 - 26) days. 9 patients in test group formed mixed chimerism (46XX/46XY) and sustained about 3 - 12 months; disease-free survival (DFS) was 63.6%, 3 patients in control group formed mixed chimerism (46XX/46XY), persistent about 3-6 months; DFS was 50.0%. It is concluded that treatment with hiDLI plus IL-2 after mix-HSCT for AML patients may increase DFS efficiently.

OBJECTIVETo assess the relationship between fractional esterification rate of high density lipoprotein cholesterol (FER(HDL)) and coronary artery disease.
METHODSA total of 131 hospitalized patients underwent coronary angiography due to chest pain were included in the study and patients were divided into CAD group (n = 76) and non CAD group (n = 55) according to coronary angiogram. Clinical and laboratory data including biochemical laboratory, FER(HDL) and lipid subclasses were analyzed.
RESULTSThe FER(HDL) value of CAD group was significantly higher than that of the non CAD group (21.70 ± 8.73 vs. 18.65 ± 6.26, P < 0.05). There was an increased trend of FER(HDL) with numbers of diseased coronary arteries, significant difference was evidenced between non CAD group and 3-vessel group (18.65 ± 6.26 vs. 24.00 ± 9.22, P < 0.05). FER(HDL) was positively correlated with TG (r = 0.647, P < 0.001), LDLb-C(r = 0.441, P < 0.001) and negatively correlated with HDL-C (r = -0.708, P < 0.001) and HDL(2)-C (r = -0.748, P < 0.001).
CONCLUSIONOur data showed that the values of FER(HDL) were significantly increased in CAD patients and correlated with the severity of the CAD.

This study was aimed to observe and analyze the effectiveness of platelet transfusion. The platelet count of 1786 patients before transfusion and on 20-24 hours after transfusion was determined by using Auto-Hematology Analyzer, the percent platelet recovery (PPR) was calculated, the platelet transfusion efficiency (PTE) was evaluated by PPR and hemorrhage presentation after platelet transfusion, and the PTE was statistically analyzed according to disease cause, transfusion frequency, platelet type and once transfusion amount. The results showed that the total PTE of 1786 patients was 52.5%. The comparison of PTE among groups of disease cause showed that PTE in leukemia and aplastic anemia (AA) was lowest, as compared with that of other diseases (P < 0.05), while PTE in operation group was highest. The comparison of PTE among groups of transfusion frequency revealed also statistical difference (P < 0.01), meanwhile PTE decreased with increasing of transfusion frequency. The comparison of PTE among groups of platelet type (platelet phoresis or platelet concentrate) showed statistical difference (P < 0.01). The comparison of PTE among groups of platelet concentrate of once transfusion amount showed no statistical difference (P > 0.05). It is concluded that the PTE closely relates with disease cause of patients, moreover transfusion frequency also associates with PTE, the more frequency of transfusion, the higher possibility of transfusion refractoriness. The PTE of platelet pheresis is obviously superior to that of platelet concentrate, while PTE of platelet concentrate not significantly relates with once adequate or not.

OBJECTIVETo evaluate the surgical treatment and technical key-points of upper or middle thoracic esophageal carcinoma in patients with history of gastrectomy.
METHODSEighty-six patients with upper or middle thoracic esophageal carcinoma after previous gastrectomy received surgical treatment between 1980 and 2004. Among them, tumor location was in middle thoracic esophagus in 50 patients, in upper thoracic esophagus in 31 and cervical esophagus in 5. Postoperative pathological staging was stage I in 16 patients, stage IIa in 62, stage IIb in 5 and stage III in 8. The interval between gastrectomy and the diagnosis of esophageal carcinoma ranged from 2 to 22 years. Surgical procedures included esophagectomy and reconstruction with nonreversed gastric tube in 2 patients and reversed gastric tube in 3. The esophagus was reconstructed with short segment of colon in 5 patients and long segment of colon in 74. Two cases underwent jejunostomy only.
RESULTSSeventy-six patients (88%) were treated with curative intent. Seven patients (8%) received palliative surgery. Postoperative complication rate was 12% (10/86). One patient died of multiple organ dysfunction syndrome (MODS). Sixty-seven patients were followed up, the 1-, 3-, 5-year survival rates were 84% (56/67), 57% (38/67) and 22% (15/67), respectively.
CONCLUSIONSSurgical treatment is the first choice for esophageal cancer patients after gastrectomy although the procedures are complicated. The surgery should be considered as a reliable therapeutic modality because of favorable patient prognosis. The replacement with colon is recommended for those patients.
