Objective:To explore the moderating effect of self-differentiation between life events and coping styles. Methods:Totally 584 college freshmen from Beijing and Jiangsu were selected to fill in the Adolescent Self-Rating Life Events Check-list (ASLEC),Differentiation of Self Inventory(DSI)and Simplified Coping Style Ques-tionnaire (SCSQ). Results:Self-differentiation had a moderating effect between life events and coping styles. The predicting effect of life events on negative coping was 0. 03 in the higher self-differentiation group (P>0. 05 ) while in the lower self-differentiation group,it was 0. 27 (P<0. 00 1 ). Conclusion:It suggests that higher self-differ-entiation could relieve the negative effect of life events to coping styles.

Objective:This study aimed to analyze and compare the prognosis and the prognostic factors of combined small cell lung cancer (CSCLC) and pure small cell lung cancer (PSCLC) retrospectively. Methods:The clinicopathological characteristics of the 343 small cell lung cancer patients who were diagnosed in Tianjin Medical University Cancer Institute and Hospital between January 2006 and December 2012 were collected and reviewed. Survival analysis was performed and prognostic factors were assessed. Results:The median OS (overall survival) and PFS (progression free survival) of CSCLC were 31 and 21 months, respectively, and the median OS and PFS of PSCLC were 15 and 9 months, respectively. The Kaplan-Meier survival curves revealed that the prognosis of CSCLC was significantly better compared with that of PSCLC. COX analysis showed that disease stage, pathology, and therapy were indepen-dent prognostic factors of small cell lung cancer. Univariate analysis indicated that the small cell lung cancer group benefited from the surgery, particularly the CSCLC. NLR , therapy, and disease stage influenced the prognosis of PSCLC, and disease stage and therapy in-fluenced the prognosis of CSCLC. Multivariate analysis revealed that disease stage and therapy were independent risk factors of CSCLC in regard to OS. Conclusion:The prognosis of CSCLC was better compared with that of PSCLC. Limited-stage small cell lung cancer should undergo surgery, particularly the CSCLC.

Objective To assess effects of the different retention time and temperature of the tumescent fluid on surgical blood loss in tumescent liposuction.Methods 20 patients with localized fat deposits received tumescent liposuction and the blood loss were calculated and compared between two treated groups.Results The mean surgical blood loss in 20 patients was (50.27± 18.56) ml with range (21.42-77.26) ml.The blood loss in liposuction with 0.5 hour retention and no retention of tumescent fluids was (19.89±7.52) ml and (26.25±12.07) ml,respectively; the blood loss in liposuction with heated (37℃) and non-heated tumescent fluid (23℃) was (28.60±6.07) ml and (29.93±9.06) ml,respectively.Conclusions A half hour retention of tumescent fluid in subcutaneous tissue after injection could reduce the surgical blood loss and the blood loss amount does not increase in the usage of a pre-heated tumescent fluid.

Objective To analyze the risk factors and clinical features of stroke following off-pump coronary artery bypass grafting in patients with prior stroke. Methods From January 2006 to July 2009, the clinical information of 437 patients undergoing OPCABC in Anzhen Hospital was collected. The patients were divided into stroke group and non-stroke group according to whether stroke occurred after operation. Preoperative and operative variants were evaluated by univariate and multivariate logistic stepwise regression analysis. Results 32 of 437 patients (7.3% ) suffered from stroke after OPCABG, 32 cases were cerebral infarction and no case was cerebral hemorrhage. There were more patients whose left ventricular ejection fraction ≤0. 50 in stroke group than that in non-stroke group (12 of 32, 37.5% versus 69 of 405, 17.0% , P = 0. 004), more patients had atrial fibrillation after operation in stroke group than that in non-stroke group (9 of 32, 28. 1% versus 27 of 405,6.7% , P ＜ 0.001), more patients had hypotension after operation in stroke group than that in non-stroke group (13 of 32,40.6% versus 42 of 405, 10. 4% ; P ＜ 0. 001), more patients had ventilatory time and ICU time after operation in stroke group than that in non-stroke group(9 of 32, 28.1% versus 49 of 405, 12.1% , P =0.021; 14of 32,43.8% versus 97 of 405, 24.0% , P = 0.013), and patients in stroke group took longer to stay in hospital than that in non-stroke group (29.0 ±15. 8 versus 22. 9 ± 10. 4, P = 0. 002 ). Logistic stepwise regression analysis showed that left ventricular ejection fraction SS0.50(OR=2.837, 95%CI: 1.238-6.498), atrial fibrillation after operation( OR =3. 065, 95% CI: 1.157-8.118) and hypotension after operation (OR =4.209, 95%CI: 1.805 -9. 813) were independent risk factors of stroke following offpump coronary artery bypass grafting in patients with prior stroke. Conclusion This data suggest that left ventricular ejection fraction ≤0. 50, atrial fibrillation and hypotension after operation are risk factors for stroke following off-pump coronary artery bypass grafting in patients with prior stroke. These patients with stroke after operation took longer to extubate and stay in ICU and hospital.

Objective To study neurologic injury after off-pump coronary artery bypass grafting (OPCABG) in elder patients with a history of stroke. Methods 108 patients (age≥60years) undergoing elective OPCABG with a history of stroke were studied. Each study patient was matched with 1 control patient who had no stroke history and was undergoing elective OPCABG either immediately before or immediately after the study patients by the same surgeon. Preoperative characteristics, ICU stay, hospital stay, hospital mortality, postoperative neurologic injury were compared in the two groups. Results The incidence of neurologic injury after operation among the study group was higher than those in control group (P＜0.01)(27.8% vs 4.6%). The incidence of delirium and stroke after operation among the study group was higher than those in control group(P＜0.05) (20.4% vs 3.7% ,7.4% vs 0.9%) ;The study group took longer to stay in ICU and hospital than the control group [(26.5±16.4)h vs (21.6±8.8)h ,(23.6±9.2)d vs(19.4±5.7)d, P＜0.01]. Logistic regression analysis showed that the risk factors of neurologic injury after OPCABG included previous stroke (OR 6. 269, 95% CI 2. 218-17. 717), age (OR 1.131,95% CI 1.032-1.239), hypertension (OR 5.072,95% CI 1. 420-18. 114) and diabetes (OR 2. 652,95% CI 1. 123-6. 260). Stroke after the operations was found in 8 of 108 study patients and included cerebral infarction in 6 and transient ischemic attack in 2. 8 patients had late stroke (＞ 24 hours).Conclusion The eldely patients with previous stroke undergoing OPCABG are more likely to have neurologic injury after operations, these patients had longer stays in ICU and hospital.

Objective To investigate the relationship among CEA, CA199, clinical pathological characteristics and prognosis in patients with rectal cancer. Methods A total of 142 patients diagnosed rectal cancer were collected for the study between January 2006 and December 2010. The clinical data including age, sex, size of tumor, differentiation, depth of tumor (T), lymph node metastasis (N), distant metastasis (M), lymphatic invasion, venous invasion, stage, and preoperative serum levels of CEA and CA199 were obtained. Patients′ follow-up ranged from 42 months to 90 months. Results Preoperative elevated CEA levels were significantly associated with distant metastasis (P < 0.05). Median overall survival time was 150 weeks in the group with normal preoperative CEA and CA199, and 101 weeks in the group with preoperative abnormal preoperative CEA and/or CA199, and Kaplan-Meier analysis showed that the difference was significant between two groups (P = 0.031). Conclusion Elevated preoperative CEA level can predict distant metastasis. The patients with abnormal preoperative CEA and/or CA199 have shorter overall survival time.

In the present study, the effect of fibroblast-mediated IL-2 gene therapy on immune and hematopoietic reconstitution was observed after syngeneic bone marrow transplantation (BMT) in the mice which had received high-dose chemotherapy. The NK activity , LAK activity and the proliferation of BMT were augmented significantly , while there were no effects on the formation of CFU-GM, CFU-MK and CFU-E of bone marrow after IL-2 gene therapy. The results suggested that fibroblast-mediated IL-2 gene therapy can accelerate and prompt the process of immune reconstitution, then enchance the antitumor effect and reduce the complication such as infection after BMT. The experiment provide basis for the application of IL-2 gene therapy in BMT in the future.
