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.

Papillary thyroid carcinoma (PTC) is the most common endocrine malignancy. It has been demonstrated that micro-RNAs (miRNAs) are involved in the development of PTC. The miRNA-chromatin immunoprecipitation microarray assay revealed down-regulation of miR-219-5p; however, the effect of miR-219-5p on PTC cell growth remains unknown. This result implied the critical role of miR-219-5p in the development of PTC.', 'We investigated the association between miR-219-5p and PTC development. Expression of miR-219-5p was monitored in 30 PTC tissue specimens and compared with that in 30 normal thyroid tissue specimens. The effect of miR-219-5p on PTC development was studied by cell proliferation, migration, and apoptosis assays. The underlying mechanism was clarified by a reporter assay and rescue experiment.', 'The current study confirmed that miR-219-5p expression was inhibited in PTC tissue samples. There were statistically significant differences in the expression of miR-219-5p with regard to sex, tumor size, and lymph node metastasis in patients with PTC. Forced expression of miR-219-5p suppressed PTC cell proliferation and migration and promoted apoptosis. Further study showed that estrogen receptor (ER) α was the direct target of miR-219-5p and mediated the effect of miR-219-5p on PTC occurrence. Expression of miR-219-5p was inversely correlated with that of ERα. Importantly, ERα overexpression in PTC cells rescued the inhibitory effect of miR-219-5p on PTC cell proliferation and migration. Thus, our results indicated that miR-219-5p played a critical role in PTC growth by inhibiting ERα.

One of the most common and severe complications of long-term parenteral nutrition (PN) is PN-associated cholestasis. The soybean oil-based lipid emulsion administered with PN has been associated with cholestasis, leading to an interest in lipid reduction strategies. The purpose of this study was to determine whether the provision of a soybean oil-based lipid emulsion at 1 g/kg/d compared with 2-3 g/kg/d is associated with a reduced incidence of cholestasis.', 'Retrospective review of neonates admitted between 2007 and 2011 with a gastrointestinal condition necessitating ≥ 21 days of PN support. Neonates were divided into 2 groups based on the intravenous lipid emulsion dose: 1-g group (1 g/kg/d) and 2- to 3-g group (2-3 g/kg/d). The primary outcome measure was the incidence of cholestasis.', 'Sixty-one patients met inclusion criteria (n = 29, 1-g group; n = 32, 2- to 3-g group). The 2 groups did not differ in any baseline characteristics other than associated comorbidities that were more common in the 2- to 3-g group. The duration of PN, the number of operative procedures and bloodstream infections, and enteral nutrition (EN) were similar between groups. The incidence of cholestasis was not different between groups (51.7%, 1-g group; 43.8%, 2- to 3-g group; P = .61), and there was no difference between groups in the time to cholestasis (32.6 ± 24.1 days, 1-g group; 27.7 ± 10.6 days, 2- to 3-g group; P = .48). Overall, 44.8% of patients with cholestasis were transitioned to full EN, and 55.2% were transitioned to a fish oil-based lipid emulsion after which the direct bilirubin normalized in all patients.

The present study aimed to identify the relationship between glycemic variability (GV) and the 10-y risk of cardiovascular disease (CVD) in type 2 diabetes mellitus (T2DM) patients with good glycemic control.', 'Two-hundred forty consecutive T2DM patients (HbA1c≤7.0%) without CVD were included to calculate the 10-y CVD risk by Framingham risk score (FRS), and divided into 3 groups: low-risk group (FRS≤10%), intermediate-risk group (>10%, ≤20%) and high-risk group (>20%). Inter-group differences of GV were determined by comparing the SD of blood glucose (SDBG), mean amplitudes of glycemic excursion (MAGE), and mean of daily differences (MODD) gathered from 72-h continuous glucose monitoring system.', 'The levels of SDBG and MAGE significantly increased along with the raises of 10-y CVD risk of T2DM patients (p<0.01). FRS was positively correlated with age, systolic blood pressure, SDBG and MAGE (r=0.717, 0.525, 0.509 and 0.485 respectively, p<0.01), while negatively correlated with the level of HDL-C (r=-0.348, p<0.01). Furthermore, multivariate logistic regression analysis confirmed that increased MAGE [OR: 1.623(1.198-2.316), p<0.001] and patients with high urine albumin excretion rates [OR: 1.743(1.247-2.793), p<0.001] were independent predictors for high 10-y CVD risk.
