Objective To analyze the mid- and long-term results after coronary artery bypass graft surgery (CABG), to evaluate the accuracy of multi-detector CT coronary angiography (MDCT) on the graft patency status and to compare the patency for different grafts. Methods One hundred and one cases underwent CABG from June 1992 to March 2008 were followed up by searching the database of MDCT (42 cases) and selective coronary angiography (SCA, 59 cases). The mean following up period was (66.79 ±44.27) months. Three hundreds and 10 grafts including 115 arterial and 195 venous were analyzed.A comparison of the patency rate between the arterial and venous grafts was also carried out. At the mean time, 2 groups were divided according to the paft lesions( patency of not). Uunivariate analysis and Logistic regression analysis were made for statistics. Results At the follow-up of (53.93 ± 36.80) months, the patent rate of LIMA, RA, SV and CV examined by MDCT was 94.7%, 92.0%, 85.9% and 60.0%, respectively. The patent rate for MDCT patients with angina was 83.5%, and 95.2% for angina-free group ( P = 0.046). At the follow-up of (75.95 ±47.09) months, the patent rate of LIMA, RA, SV and CV examined by SCA was 87.1%, 81.0%, 53.6% and 57. 1%, respectively. In SCA patients the patent rate was 62.0% for angina group and 100% for angina-free group ( P = 0.025 ). According to logistic regression analysis, only the postoperative period was statistically related to the graft lesion. Conclusion MDCT could find out the occlusions and obvious stenoses of the grafts after CABG. It might be served as a noninvasive method to evaluate the grafts patency postoperatively. The mid- and long-term patency of arterial grafts is better than venous grafts. Graft lesion is an important factor leading to postoperative recurrent angina pectoris. The severity of the graft lesion has a close relation to the lenth of postoperative period.

Objective To investigate the biological effect of anti-leukemic cells induced by eosinophilic granulocyte (EOS) in bone marrow of patients with chronic myelogenous leukemia (CML).Methods The BCR-ABL fusion gene as well as the expression of IL-12 and IL-17 mRNA were performed by RT-PCR.The serum concentrations of cytokine IL-12 and IL-17 were determined by enzyme-linked immuno sorbent assay (ELISA).Immunochemistry staining and cytochemistry staining were used to observe the peroxydase (POX) and human Leukocyte antigen (HLA)-DR expression of EOS in bone marrow.Immunofluorescence staining was used to observe mannose receptor (MR),IL-12,IL-17A and IL-17receptor A (IL-17RA) expression of EOS.The results between the CML patients and the healthy controls were compared.Results Serum levels of IL-12 and IL-17 were higher in the 60 CML patients [(196.33 ±21.79) ng/L and (36.55-±3.01) ng/L] than those in the controls [(96.60 ±4.92) ng/L and (23.74 ±1.36) ng/L].In the 32 patients with activated EOS,the levels of IL-12 and IL-17 were (273.12 ± 17.16)ng/L and (40.11 ± 6.13) ng/L,which were significantly higher than those in the non-activated EOS [(126.16 ± 14.27) ng/L and (28.14 ±5.29) ng/L] (P values <0.01).IL-12 and IL-17 mRNA were expressed in activated EOS,while BCR-ABL fusion gene was not found.The amounts of EOS were increased abnormally in the bone marrow and peripheral blood of the CML patients with POX positive staining in the cytoplasm and weakly positive HLA-DR staining.It was observed easily by a microscope that EOS could attack leukemic cells in bone marrow through adhesion,capture and phagocytosis.Activated EOS could express IL-12,IL-17A and MR,which was related with the serum levels of these cytokines.Conclusions Activated EOS in bone marrow of CML patients could express IL-12 and IL-17.Activated EOS could induce coup injury to leukemic cell by releasing POX and expressing IL-12 and IL-17.It can also capture or swallow target cells via the expression of MR on the membrane.EOS may play an important role in the anti-tumor immunologic function in bone marrow of CML patients.

Background and purpose:Pathological lymph node metastasis (LNM) is not rare in clinical lymph node negative (cN0) papillary thyroid carcinoma (PTC). The aim of this study was to investigate the risk factors of LNM, especially of high volume LNM (more than 5 metastatic lymph nodes) and contralateral central compartment LNM, in cN0 PTC.Methods:Medical records of 350 PTC patients (265 female, 85 male, 212 patients with solitary lesion in unilateral lobe) were reviewed. All operations of these patients were performed by one surgical team. The clinical pathological data were collected, and univariate and multivariate analysis was performed.Results:LNM was conifrmed in 138 patients (39.4%) and 20 patients had high volume LNM. In 169 patients with solitary lesion in unilateral lobe with total thyroidectomy and bilateral central neck dissection, 24 patients had contralateral metastasis (14.2%). In univariate analysis, tumor size (58.5% in >1 cmvs 33.6% in≤1 cm) and tumor with calcification in preoperational ultrasonography (43.7% withvs 31.7% without) showed signiifcant difference in prevelance of LNM. In multivariate analysis, tumor size >1 cm (OR=2.792) was the independent risk factor of LNM. Gender (3.8% in male vs 11.8% in female), age (10.7% <40 yearsvs 3.4%≥40 years ), tumor size(13.4% in >1 cmvs 3.4% in≤1 cm) and tumor with low echo in preoperational ultrasonography (13.9% withvs 4.8% without) showed signiifcant difference in univariate analysis of high volume LNM. Male (OR=5.152), tumor size >1 cm (OR=5.712) and age <40 years (OR=3.959) were conifrmed as independent risk factors of high volume LNM. Male (OR=3.105) and tumor size >1 cm (OR=3.863) were also demonstrated as independent risk factors of contralateral LNM in patients with solitary lesion in unilateral lobe, the prevalence of LNM were 26.5% in male and 26.1% in tumor size >1 cm, respectively.Conclusion:LNM was not “rare” in cN0 PTC patients. Prophylactic central neck dissection should be performed in cN0 patients with tumor size >1 cm. For cN0 microcarcinoma, more active surgical treatment may be considered in male and young patients.

Objective To compare the safety , surgery effects , pain scores of the close-distance-two-port video-assisted lobectomy and systematic dissection of the mediastinal nodes , and single-port video-assisted thora-coscopic surgery (VATS). Methods Between October 2012 and January 2015 in Peking University First Hospi-tal and Beijing Hospital , 269 patients who were going to be performed lobectomy and systematic lymph node dissection, were gathered and 205 patients were included in this study finally. Of the total, 122 patients were performed close-distance-two-port VATS , and 83 patients underwent single-port VATS. The clinical data were gathered, and statistically analyzed. Result In both groups, no severe postoperative complications or death oc-curred. No significant differences existed between the two groups in terms of intraoperative blood loss , duration and volume of chest tube drainage , postoperative pain score , hospital stay after surgery and hospitalization ex-penses (P > 0.05) but the data about operating time, number of dissected lymph nodes, complications(subcuta-neous emphysema , air-leak from the port of drainage tube and poor wound healing ) were significantly different (P < 0.05). Conclusions Compared with the single-port VATS, the method of close-distance-two-port video-as-sistant lobectomy and systematic dissection of the mediastinal nodes is safe and practicable with definite thera-peutic effect, less operation difficulty and complications.
