Objective To investigate the role of Twist and vascular endothelial growth factor (VEGF)in the development of epithelial ovarian cancer and their relationship with clinical pathological features.Methods The expressions of Twist and VEGF were detected by immunohistochemical staining (SP)method in 80 cases of epithelial ovarian cancer and 10 paired cases of normal ovarian tissue.Results In the 80 cases of ovarian cancer tissues,the positive expression rate of Twist and VEGF in epithelial ovarian cancer was 85% and 86.25%,respectively,which were remarkably higher than those in normal ovarian tissues (P <0.01).The expressions of Twist and VEGF were closely associated with clinical stages,pathological grades and lymph node metastasis,but not correlated with age or pathological patterns (P >0.05).There was a significant correlation between the expressions of Twist and VEGF in epithelial ovarian cancer (r =0.646,P <0.01).Conclusion The high expressions of Twist and VEGF may play a potential role in the occurrence,development and invasion process of epithelial ovarian cancer.

Objective: By taking the holism and differentiation concepts of traditional Chinese medicine (TCM) as the guidance, physical, mental and workplace factors were recruited in the observation of depression in employees, and were systematically classified to establish a workplace-related Liver Meridian-depression scale, for providing an evaluation index for depression in employees. Methods: NVIVO 11 software was adopted to assort ancient TCM classics. Based on the holism and differentiation concepts of TCM and well-developed scales, the item pool was determined via brain storm and screened by Delphi method after classified; a Wechat questionnaire was handed out 240 times via the online system 'Wen Juan Xing', and the results were statistically analyzed by the SPSS 17.0 version software. Results: Five dimensions consisting of 80 items were obtained after classification, and 60 items were selected by Delphi method; a total of 216 questionnaires were returned and the return rate was 90%. Of which, 215 questionnaires were valid ones, and the valid rate was 99%. By exploratory factor analysis (EFA), 44 items were obtained, and the aggregate split-half reliability coefficient was 0.922. The Cronbach's alpha coefficient for the five dimensions, i.e. Liver Meridian, relevant meridians, basic psychological activities, work cognition and emotional reactions, was respectively 0.841, 0.842, 0.914, 0.836 and 0.839, indicating a content internal consistency. The score of each item was highly correlated with the corresponding dimension, and the intercommunity was between 0.474 and 0.801. Nine factors were generated, 2 in the dimension of Liver Meridian, 3 in the dimension of relevant meridians, 2 in the dimension of basic psychological activities, 1 in the dimension of work cognition, and 1 in the dimension of emotional reactions, and the load of each factor was between 0.438 and 0.859. The reliability and validity of the scale were well examined. Conclusion: The scale can be applied to evaluate the qi activities of Liver Meridian and depression symptoms related to workplace.

In under - correction cases with concomitant esotropia, 6 cases were performed resection of lateral rectus muscle, the corrective extent was (4. 03±0. 98) ? /mm; 6 cases were performed resection of lateral rectus muscle and recession of medial rectus muscle, the corrective extent was (6. 86 ± 1. 32) ? / mm; 3 cases were performed recession of medial rectus muscle, the corrective extent was ( 4. 33 ± 0. 29 ) ? / mm. In over -correction cases with concomitant exotropia, 16 cases were performed advance of lateral rectus muscle, the corrective extent was (5. 37 ± 1. 56) ? / mm; 6 cases were performed recession of medial rectus muscle, the corrective extent was (6. 29 ± 3. 68) ? / mm; 5 cases were performed advance of lateral rectus muscle and recession of medial rectus muscle, the corrective extent was (5. 46±1. 78) ? / mm; 1 case were performed resection of lateral rectus muscle, the corrective extent was 5. 00? / mm. In under - correction cases with concomitant exotropia, 12 cases were performed resection of medial rectus muscle, the corrective extent was (4. 47 ± 0. 54) ? / mm; 16 cases were performed recession of lateral rectus muscle and resection of medial rectus muscle, the corrective extent was ( 5. 11 ± 0. 75 ) ? / mm; 2 cases were performed recession of lateral rectus muscle, the corrective extent was (2. 65±0. 42) ? / mm.
CONCLUSION: In reoperation of concomitant strabismus patients with over-correction, weakening or/and strengthening the horizontal muscle which were performed surgery before has a greater and more unstable surgical corrective extent. While In reoperation of concomitant strabismuspatients with under -correction, weakening or/ and strengthening the horizontal muscle which were not performed surgery has a normal corrective extent as usual.

AlM:To observe the changes of binocular vision in V-pattern exotropia children before and after surgical correction, and the effect of training in reconstructing the binocular vision after surgical corrections.METHODS: Sixty V-pattern exotropia children were enrolled in this study and were divided into three groups according to their age:group A (4~6 years old), group B (7~9 years old), and group C (10~12 years old), 20 cases for each group. Patients received routine refraction and ophthalmic examinations. Distance and near deviation were measured by prism-covering method and synoptophore. The simultaneous perception and fusion were examined with a synoptophore, and the stereacuity was measured with stereograms ( Titmus) . The children who didn’t reconstruct binocular vision function 1wk after surgery received binocular vision training. The data were recorded before and 1 , 2, 4, and 8wk after surgery. RESULTS: Binocular vision significantly improved among the children after surgery in group A and B ( P<0. 05 ) . Significantly divergence showed between group C and the other groups 1wk after surgery ( P < 0. 05 ). Binocular vision of the three groups all significantly improved 8wk after surgery, with no significant differences (P>0. 05). CONCLUSlON: V - pattern exotropia children can benefit from early surgical correction and training after surgery in reconstruct binocular vision.

Objective To evaluate the efficacy of nursing in percutaneous coronary intervention (PCI)for a patient with myocardial infarction and heart failure under the support of extracorporeal membrane oxygenation (ECMO). Methods An 85-year-old man suffered from myocardial infarction twice during 1-month hospitalization and complicated with a severe heart failure (eject fraction is 27%), pleural effusion and pulmonary infection. We decide to perform PCI under the support of ECMO for his hemodynamic instability. The key point of nursing in PCI under the support of ECMO: On the one hand, pre-PCI interview and preparation of all the drugs and items needed in operating ECMO 1 day in advance were key steps to guarantee the successful operation. On the other hand, high standard nursing technique, mastery of knowledge about ECMO and tacit cooperation with doctor were the bases of the successful operation. Results Under the support of ECMO, the patient' s hemodynamic condition came to stable. He underwent the coronary angiography and was implanted a stent in left coronary artery successfully under the meticulous care of doctor and nurse. Conclusions ECMO could provide life support for patients with severe heart failure. The adequate preparation for ECMO could guarantee the successful operation for nurse in catheter lab. Both intra-operative warming and prevention of postPCI fever caused by cold stimulation are important nursing measures.
