instruction:
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.
question:
To investigate the effect of 1,25-dihydroxyvitamin D3 (1,25VD3) on house dust mites (HDM)-induced expression of thymic stromal lymphopoietin (TSLP) in human airway epithelial cells in vitro.', 'Human airway epithelial 16HBE cells were incubated with 200, 400, and 800 U/L in the absence or presence of 1,25VD3 (10(-8) mol/L) for 6 h and 24 h, and TSLP mRNA and protein expressions in the cells were assessed using quantitative PCR and ELISA.', '16HBE cells incubated with HDM at 200, 400, and 800 U/L showed significantly increased TSLP mRNA and protein expressions (P<0.05). Pretreatment of the cells with 1,25VD3 obviously lowered 400 U/L HDM-induced TSLP expressions (P<0.05), but 1,25VD3 added along with HDM in the cells did not produce significant effects on TSLP expressions (P=0.58).

question:
To compare oncologic outcomes in a contemporary series of patients undergoing radical cystectomy (RCX) by the laparoscopic or open approach.', 'Laparoscopic RCX with extracorporeally constructed urinary diversion is a safe and effective operation for appropriate patients with bladder cancer. Perioperative and functional outcomes are comparable with open surgery. Worldwide experience continues to increase; more than 1000 surgeries have already been performed. Intermediate-term oncologic outcomes appear to be comparable to open approach.

question:
Long non-coding RNAs (lncRNAs) constitute a novel class of non-coding RNAs that take part in occurrence and development of diabetes complication via regulating gene expression. However, litter is known about lncRNAs in the setting of diabetes induced nephropathy. The aim of this study was to examine whether lncRNA-myocardial infarction-associated transcript (MIAT) is involved in diabetes induced renal tubules injury.', 'Adult Wister rats were randomly assigned to receive intraperitoneal STZ (65\xa0mg/kg) to induce diabetes. Rats treated with equal volume of citrate buffer were as control. Renal function was evaluated by analysis of serum creatinine and blood urea nitrogen (BUN) every four weeks after STZ administration. Also tubules of all rats were collected for determination of MIAT and Nrf2 level at the corresponding phase. The in\xa0vitro high glucose-triggered human renal tubular epithelial cell line (HK-2) was used to explore the mechanism underling MIAT regulated high glucose-induced tubular damage.', 'In diabetic rats, MIAT showed the lower level and its expression is negatively correlated with serum creatinine and BUN. Consistent with diabetic rat, exposed to high glucose, HK-2 cells expressed lower level of MIAT and Nrf2, and also showed reduction in cell viability. By pcDNA-MIAT plasmid transfection, we observed that MIAT overexpression reversed inhibitory action of Nrf2 expression by high glucose. Moreover, the data of RNA pull-down and RIP showed that MIAT controlled Nrf2 cellular through enhancing Nrf2 stability, which was confirmed by CHX and MG132 administration. Inhibitory effect of cell viability by silencing MIAT was also reversed by Nrf2 overexpression.
