TASK DEFINITION: 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.
PROBLEM: To study the healing effect of recombinant human epidermal growth factor (hEGF) on diabetic foot ulcers.', 'A total of 127 consecutive patients were screened and 61 diabetic subjects were recruited into this double-blind randomized controlled study. Predetermined criteria were used for diagnosis and classification of the diabetic wound. The patients were randomized into three groups. All patients attended our Diabetes Ambulatory Care Center every other week for joint consultation with the diabetologist and the podiatrist. Group 1 (control) was treated with Actovegin 5% cream (Actovegin), group 2 with Actovegin plus 0.02% (wt/wt) hEGF, and group 3 with Actovegin plus 0.04% (wt/wt) hEGF. The study end point was the complete closure of the wound. Failure to heal was arbitrarily defined as incomplete healing after 12 weeks.', 'Final data were obtained from 61 patients randomly assigned into three groups. The mean ages of the patients, wound sizes, wound duration, metabolic measurements, and comorbidities were comparable within groups, except that group 3 had more female patients. Mean follow-up for the patients was 24 weeks. Data were cutoff at 12 weeks, and results were analyzed by intention to treat. After 12 weeks, in group 1 (control) eight patients had complete healing, two patients underwent toe amputation, and nine had nonhealing ulcers. In group 2 (0.02% [wt/wt] hEGF) 12 patients experienced wound healing, 2 had toe amputations, and 7 had nonhealing ulcers. Some 20 of 21 patients in group 3 (0.04% [wt/wt] hEGF) showed complete wound healing. Healing rates were 42.10, 57.14, and 95% for the control, 0.02% (wt/wt) hEGF, and 0.04% (wt/wt) hEGF groups, respectively. Kaplan-Meier survival analysis suggested that application of cream with 0.04% (wt/wt) hEGF caused more ulcers to heal by 12 weeks and increased the rate of healing compared with the other treatments (log-rank test, P = 0.0003).

PROBLEM: We have previously demonstrated that sophorolipids, a class of easily chemoenzymatically modifiable glycolipids, possess anti-inflammatory effects in vitro and in vivo. Since glycolipids have been shown to have anticancer activity, we investigated the effects of sophorolipids and their derivatives against pancreatic cancer.', 'Human pancreatic carcinoma cells were treated with increasing concentrations of sophorolipid natural mixture or select derivatives (ethyl ester, methyl ester, ethyl ester monoacetate, ethyl ester diacetate, acidic sophorolipid [AS], lactonic sophorolipid diacetate [LSD]) for 24 h and assessed for cell necrosis (cytotoxicity-lactate dehydrogenase release). Controls consisted of cells treated with media or vehicle alone and sophorolipid treatment of peripheral blood mononuclear cells.', 'Sophorolipids demonstrated anticancer activity against human pancreatic carcinoma cells. Natural mixture mediated consistent cytotoxicity at all doses tested (20 +/- 4%). However, methyl ester derivative mediated much greater levels of cytotoxicity (63 +/- 5%) compared with other derivatives (ethyl ester diacetate, 36 +/- 6%, ethyl ester monoacetate, 18 +/- 7%; P < 0.05). In contrast, LSD- and AS-mediated toxicity was inversely proportional with dose (LSD, 40.3% at 0.5 mg/mL, 3.4% at 2.0 mg/mL; AS, 49% at 0.5 mg/mL, 0% at 2.0 mg/mL). Sophorolipid treatment did not affect peripheral blood mononuclear cells at all doses tested.

PROBLEM: Notch signaling is indicated as novel therapeutic targets to prevent recurrence of breast cancer. LncRNAs were identified as downstream target of Notch pathway. However, the exact mechanisms involved in Notch signaling, lncRNAs and breast cancer remain to be explained.', 'This original research aimed to determine the prognostic implications of Notch-1 for breast cancer, and explain mechanisms involved in regulation of lnRNA GAS5 by Notch-1, and identify the function of this mechanism on breast cancer.', 'Thirty breast cancer patients were included from The First Affiliated Hospital of Anhui Medical University (China) since January 2006 in this study. The mRNA level by RT-PCR and protein level of Notch-1 by western blot in tumor tissues and adjacent normal tissues were evaluated and 5-year survival analysis was applied to examine the significance of Notch-1. The levels of ten reported lncRNAs were determined by RT-PCR, and subsequently linear analysis was applied to analyze the relationship between these four unique lncRNAs and protein level of Notch-1, which identified the most relevant lncRNA GAS5 with Notch-1 in breast cancer. Subsequently, Notch1-siRNA was applied to influence the expression of Notch-1 in T47D, then the level of RSA5 was measured by RT-PCR, and CCK-8 assay was applied to measure the proliferation of T47D cells.', 'High level of Notch-1 provided a poor prognosis in breast cancer. Interference of Notch-1 significantly suppressed proliferation of T47D cell (P < 0.05), and significantly increased the level of GAS5.
