Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Input: Consider Input: Baseline carbohydrate antigen 19-9 (CA 19-9) is a useful prognostic marker in pancreatic ductal adenocarcinoma (PDA); however, data on the significance of a change in CA 19-9 following neoadjuvant therapy are lacking.', "All patients receiving neoadjuvant therapy for PDA from July 2010 to February 2013 were retrospectively reviewed. Resection rate, R0 resection rate, need for venous resection, and overall survival were correlated to CA 19-9 response. Fisher's exact test, Kaplan-Meier survival analysis, and multivariate analysis using Cox regression were used.", 'A total of 78 patients were studied (21 patients with resectable disease, 40 borderline resectable, and 17 with locally advanced disease). A variety of chemotherapies ± radiation were utilized during the study period. Overall, 56 patients (72 %) had a decrease in CA 19-9 of >50 % with neoadjuvant treatment. In borderline resectable patients, CA 19-9 response of >50 % predicted R0 resection (odds ratio 4.2; p = 0.05). In borderline resectable patients who had an increase in CA 19-9, none of five (0 %) underwent R0 resection compared with 80 % of the remaining cohort (p = 0.001). The complete pathologic response rate was 29 % in patients who had a CA 19-9 response of >90 % versus 0 % in the remaining patients (p < 0.001). A CA 19-9 response of >50 % resulted in improved overall survival (28.0 vs. 11.1 months; p < 0.0001) and was an independent predictor of survival (hazard ratio 0.26; 95 % CI 0.13-0.55; p < 0.0001).

Input: Consider Input: Cullin1 is a scaffold protein of the ubiquitin E3 ligase Skp1/Cullin1/Rbx1/F-box protein complex which ubiquitinates a broad range of proteins participating in biochemical events like cell-cycle progression, signal transduction, and transcription. Cullin1 is involved in the progression of several cancers, such as melanoma, breast cancer, and gastric cancer.', "To investigate the role of Cullin1 in the development of non-small-cell lung cancer (NSCLC), we examined the expression of Cullin1 in 8-paired fresh NSCLC tissues. We then constructed immunohistochemistry (IHC) on 114 paraffin-embedded slices and evaluated the correlation between Cullin1 expression and clinicopathologic variables, as well as patients' overall survival.", "We found that Cullin1 was highly expressed in NSCLC tissues and significantly associated with NSCLC's histological differentiation (P=0.002), clinical stage (P=0.010) and Ki-67 (P=0.021). Furthermore, we showed a strong correlation between high Cullin1 expression and worse overall survival rates in NSCLC patients (P<0.001). Cox regression analysis revealed that Cullin1 expression was an independent prognostic factor to predict 5-year patient outcome in NSCLC cancer (P=0.033).

Input: Consider Input: Insufficient insulin secretion or inefficient insulin response are responsible for the clinical outcome of type\xa02 diabetes mellitus. Administration of insulin alone is prone to cause secondary effects, resulting in an unsatisfactory outcome. Shen-Qi-Formula (SQF), a well-known Chinese medicinal formula, has been used for diabetic treatment for a long time. The present study was designed to investigate whether SQF in combination with insulin improved the clinical outcome of type\xa02 diabetes mellitus, and what mechanisms were possibly involved in the treatment.', 'A total of 219 patients were included in the study. Of these, 110 patients were treated with insulin monotherapy, and 109 with the combination therapy of SQF and insulin. Before and after 12-week treatment, the fasting blood glucose, postprandial blood glucose, β-cell function, insulin resistance and blood lipids were measured.', 'The 12\xa0weeks of SQF treatment in combination with insulin significantly decreased the fasting and postprandial blood glucose levels. Insulin secretion was not increased after the treatment, but β-cell function and insulin resistance were obviously improved. Furthermore, 12\xa0weeks of treatment with SQF and insulin improved the levels of glucagon-like peptide-1, oxidative stress, blood lipids, coagulation function and bodyweight.
