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: 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.

Input: Consider Input: Rush immunotherapy (RIT) presents an attractive alternative to standard immunotherapy. However, RIT carries a much greater risk of acute allergic reactions, including anaphylaxis.', 'We hypothesized that omalizumab, a humanized monoclonal anti-IgE antibody, would be effective in enhancing both safety and efficacy of RIT.', 'Adult patients with ragweed allergic rhinitis were enrolled in a 3-center, 4-arm, double-blind, parallel-group, placebo-controlled trial. Patients received either 9 weeks of omalizumab (0.016 mg/kg/IgE [IU/mL]/mo) or placebo, followed by 1-day rush (maximal dose 1.2-4.0 mug Amb a 1) or placebo immunotherapy, then 12 weeks of omalizumab or placebo plus immunotherapy.', 'Of the 159 patients enrolled, 123 completed all treatments. Ragweed-specific IgG levels increased >11-fold in immunotherapy patients, and free IgE levels declined >10-fold in omalizumab patients. Patients receiving omalizumab plus immunotherapy had fewer adverse events than those receiving immunotherapy alone. Post hoc analysis of groups receiving immunotherapy demonstrated that addition of omalizumab resulted in a 5-fold decrease in risk of anaphylaxis caused by RIT (odds ratio, 0.17; P = .026). On an intent-to-treat basis, patients receiving both omalizumab and immunotherapy showed a significant improvement in severity scores during the ragweed season compared with those receiving immunotherapy alone (0.69 vs 0.86; P = .044).

Input: Consider Input: The fruits of Vitex rotundifolia L. are widely used to treat inflammation of the airway in Traditional Chinese medicine. Previous studies found that casticin, isolated from Vitex rotundifolia, could induce apoptosis of tumor cells. In this study, we evaluated the anti-inflammatory effects of casticin and its underlying molecular mechanism in lipopolysaccharide (LPS)-stimulated macrophages.', 'RAW264.7 cells were pretreated with various concentrations of casticin (0.3-10μM), and then treated with LPS to induce inflammation. We assayed the levels of proinflammatory cytokines and prostaglandin E2 (PGE2) using ELISA, and examined the protein expression of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2, and heme oxygenase (HO)-1 by Western blot. We also investigated the anti-inflammatory molecular mechanism by analyzing inflammatory-associated signaling pathways, including the nuclear transcription factor kappa-B (NF-κB) and mitogen-activated protein kinase (MAPK) pathways.', 'We found casticin inhibited the levels of nitric oxide and PGE2, and decreased the production of proinflammatory cytokines such as interleukin (IL)-1β, IL-6, and tumor necrosis factor α (TNF-α). In addition, iNOS and COX-2 expression levels were suppressed and casticin increased HO-1 and Nrf2 production in a concentration-dependent manner. Furthermore, casticin significantly inhibited NF-κB subunit p65 proteins in the nucleus and decreased Akt and MAPK activation.
