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.

[EX Q]: Poor condition at operation determined by the physiologic POSSUM score is related to postoperative mortality and morbidity of colorectal cancer surgery. This study was designed to analyze the relationship between condition of patients with colorectal cancer at operation and long-term overall survival.', 'A total of 542 patients survived a radical resection for Stages I, II, or III colorectal cancer. Physiologic POSSUM score at surgery, exclusive of age, was calculated for all patients. Mean physiologic POSSUM score was used as cutoff point to determine low-risk and high-risk group patients. A Cox proportional hazard analysis was performed to study the effect of low-risk and high-risk group on overall survival and to identify independent risk factors.', 'Five-year overall survival was significantly higher in low-risk group patients than in high-risk group patients (low-risk group 66.6 percent vs. high-risk group 48.5 percent; P < 0.001). Differences in overall survival also were found when patients in Stages I, II, and III were analyzed separately. Risk factors for overall survival were advanced stage of disease, poor tumor differentiation, mucinous adenocarcinoma, older than age 70 years, and poor condition of the patient at time of operation.

[EX Q]: To probe into an new methods preserving parathyroid gland of patients with thyroid carcinoma.', 'Thirty-six patients with thyroid carcinoma that primary treated were random divided into two groups: trial group and control group. Emulsion of activated-carbon particles was injected into the thyroid gland of trial group patients. After thirty minutes, central compartment dissection was performed in the all patients. The black stained tissue in the dissection specimen of trial group was separated. Total lymph node, metastasis lymph node and parathyroid gland in the black stained tissue, and non-black stained tissue in the central compartment dissection specimen of trial group and central compartment dissection specimen of control group were counted respectively.', 'Nineteen and twenty central compartment dissection was performed in trial group and control group respectively. There are 177 lymph nodes included 83 metastasis lymph nodes in the black-stained tissue of central compartment dissection specimen of trial group. No parathyroid gland was found in the black-stained tissue. Nine lymph nodes included 2 metastasis lymph nodes and 7 parathyroid glands were found in the non-black stained tissue of central compartment dissection specimen of trial group. There were 124 lymph nodes included 80 metastasis lymph nodes and 8 parathyroid glands in central compartment dissection specimen of control group. There are statistic difference between the amount of lymph node in black stain tissue and that of control group (t = 0.340, P = 0.003). Rate of staining lymph node were 95.2 percent.

[EX Q]: BACKGROUND/AIMs: Pleiotrophin (PTN) have been demonstrated to play an important role in the development of human gastric cancer. However, the prognostic value remains unclear. The aim of this study was to investigate whether expression of PTN has prognostic relevance in human gastric cancer.', 'Immunohistochemistry was used to investigate the expression of PTN proteins in 178 patients with gastric cancer. The level of PTN mRNA in gastric cancer tissues and paratumor tissues were evaluated in 52 paired cases by quantitative real-time polymerase chainreaction(qRT-PCR). Survival analysis by the Kaplan-Meier method was performed to assess prognostic significance.', 'The expression level of PTN in gastric cancer tissues was significantly higher (P<0.001) than those in paratumor tissues according to the immunohistochemistry analysis, which was confirmed by qRT-PCR analysis. Additionally, the overexpression of PTN was significantly associated with the tumor site (P=0.001), Lauren’s classification (P<0.001),histologic differentiation(P=0.014),depth of invasion(P<0.001), TNM stage (P=0.003),and lymph node metastasis (P=0.002). Moreover, the Cox proportional- hazards regression analysis revealed that the increased expression of PTN was an independent prognostic factor for poor recurrence-free survival(RFS) and overall survival(OS)(both P<0.001).
