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.

Example Input: We aimed to investigate the anti-angiogenic properties of miR-155 via in vitro and in vivo studies.', 'miR-155 was knocked down using lentivirus-mediated RNA interference. The proliferation, migration, and tube formation of human retinal microvascular endothelial cells (HRMECs) were measured using BrdU, Transwell, and Matrigel assays, respectively. An oxygen-induced retinopathy (OIR) model was induced using neonatal C57BL/6J pups. Anti-miR-155 was intravitreally injected on postnatal day 12, and the retinal non-perfused areas and extent of neovascularization were measured on postnatal day 18 using transcardiovascular fluorescein isothiocyanate (FITC)-dextran perfusion and retina sections. A laser-induced choroidal neovascularization (CNV) model was induced in adult C57BL/6J mice. To evaluate the leakage areas, fundus fluorescein angiography was performed on day 14 after anti-miR-155 intravitreal injection. The neovascularization area of the CNV model was also examined in confocal and retina section studies. The expression levels of SHIP1 and p-Akt (Thr308, Ser473, and Thr450) were evaluated both in vitro and in vivo.', 'The expression of miR-155 was elevated in HRMECs after treatment with vascular endothelial growth factor (VEGF) and in neovascularized mouse model retinas. Anti-miR-155 lentivirus reduced the VEGF-induced proliferation, migration, and tube formation abilities of HRMECs. Anti-miR-155 attenuated retinal neovascularization in in vivo CNV and OIR models. In VEGF-treated HRMECs and retina neovascularization models, p-Akt (Ser473) was significantly upregulated, while SHIP1 was downregulated. Conversely, the inhibition of miR-155 restored the expression of SHIP1 and reduced the phosphorylation of effectors in the Akt (Ser473) signaling pathway.

Example Input: To investigate the relationship between the damages of hand functions and the type of cerebral palsy (CP) in children with CP.', 'A total of 280 children aged 4-12 years old with CP in the 20 districts of Chengdu were included. The damages of hand functions were assessed with the Chinese Version of Manual Ability Classification System (MACS) and its relationship with the type of CP were analyzed.', 'Among the 280 investigated children, there were 195 chidren with spastic CP, which accounted for the largest proportion (69.64%), wherein the spastic diplegia was most common (56.41%). The classification of MACS was level I-II in 65.13% children with spastic CP, whereas the classification of MACS was level IU-V in 84. 44% and 80.95% children with mixed and dyskinetic CP, respectively. With the increase of the degree of cognitive dysfunction in children with CP, the level of MACS was also increased. There was a difference between the classification of MACS and the different type of CP (P<0.05). The children with spastic CP were mostly mild hand dysfunction, while the children with mixed and dyskinetic type of CP were mostly middle and severe hand dysfunction. A positive correlation was found between the MACS and the subtype of spastic CP (r=0.541, P<0.05). In most of the children with diplegia from spastic CP, the hand dysfunction was mild, whereas the children with quadriplegia from spastic CP were mostly middle and severe hand dysfunction.

Example Input: Completeness of cytoreduction is a significant predictor of long-term outcome after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Imaging has limited sensitivity to identify peritoneal metastases and therefore predict whether complete cytoreduction is possible. We reviewed our experience using laparoscopy to determine candidates for complete cytoreduction and HIPEC.', 'This single-center, retrospective study examined patients from 2007 to 2014 who underwent laparoscopy to determine complete cytoreduction (CC-0/1)/HIPEC candidacy. Preoperative, intraoperative, and postoperative data were collected.', 'A total of 145 laparoscopies were performed on 141 patients, 72 (51.1\xa0%) of whom were female, with a median age of 53\xa0years (range 20-79). The primary site was appendiceal in 67 (47.5\xa0%) patients, colorectal in 43 (30.5\xa0%), mesothelioma in 17 (12.1\xa0%), unknown in 9 (6.4\xa0%), small bowel in 3 (2.1\xa0%), gastric in 1, and ovarian in 1 (0.7\xa0% each). Overall, 115 (81.6\xa0%) patients had prior abdominal surgery, 111 (76.6\xa0%) had evidence of disease on imaging, and 117 (80.7\xa0%) underwent prior chemotherapy, with a median of 5.9\xa0weeks between the last treatment and laparoscopy (0.9-498.9\xa0weeks). Four (2.8\xa0%) intraoperative complications were observed (one liver laceration, two enterotomies, and one air embolus), and nine (6.2\xa0%) postoperative complications [four (2.8\xa0%) Clavien grade (CG) I, three (2.8\xa0%) CG II, one (0.7\xa0%) CG III (return to operating room) and one (0.7\xa0%) CG IV (transient ischemic attack)]. Forty-eight patients deemed candidates by laparoscopy underwent CRS/HIPEC (positive predictive value 82.8\xa0%).
