Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

[Q]: To investigate the relationship between mean platelet volume (MPV) and glycometabolic indices, to compare MPV according to HbA1c levels, and to analyse the difference in MPV between patients with and without microvascular complications.', 'This retrospective study was conducted on 60 Type 2 diabetic patients and 50 age- and sex-matched non-diabetic controls. We obtained demographic, clinical and laboratory data including MPV, platelet count, fasting and postprandial blood glucose (FBG and PBG), haemoglobin A1c (HbA1c), lipid profile, creatinine, systolic and diastolic blood pressure (BP) in patient and control groups, and diabetic microvascular complications including nephropathy, neuropathy, and retinopathy in the patient group. All analyses were performed using SPSS version 15.0 for Windows.', 'Mean platelet volume in the diabetic group was higher than in the control group (p = 0.001). Mean platelet volume was positively correlated with FBG and HbA1c levels (p = 0.03 and p < 0.001, respectively). It was also negatively related to platelet count (p < 0.001). Mean platelet volume in patients with HbA1c > 7% was significantly higher than those with HbA1c 7% (p < 0.001). Mean platelet volume was significantly increased in patients with retinopathy compared to those without retinopathy (p = 0.04).
[A]: Is mean platelet volume associated with glycaemic control and retinopathy in patients with type 2 diabetes mellitus?

[Q]: Recently, there has been increasing concern about adverse health effects of exposure to desert dust events. However, the association between dust and the incidence of ischemic heart diseases is unknown. The aim of the present study was to elucidate whether Asian dust (AD), a windblown sand dust originating from mineral soil in China and Mongolia, is associated with the incidence of acute myocardial infarction (AMI).', 'We investigated the data regarding hospitalization because of AMI among 3068 consecutive patients from 4 AMI centers in Fukuoka, Japan, and data for AD from April 2003 to December 2010. We applied a time-stratified case-crossover design to examine the association between AD and the incidence of AMI. Using a conditional logistic regression analysis, we estimated the odds ratios of AMI associated with AD after controlling for ambient temperature and relative humidity. The occurrence of AD events 0 to 4 days before the day of admission was significantly associated with the incidence of AMI. In particular, the occurrence of AD 4 days before admission was significantly associated with the onset of AMI.

[Q]: To explore the effect of artesunate (ART) on cell differentiation and cell cycle distribution of the prostate cancer cell line PC-3 in vitro.', 'PC-3 cells were cultivated with ART from logarithmic growth phase. After 48-hour treatment, the cell cycles were detected by flow cytometry (FCM), and enzyme linked immunosorbent assay was used to detect the level of prostate specific antigen (PSA) in cell culture supernatant. The change of cellular morphology was observed under a transmission electron microscope (TEM).', 'In comparison with the blank control group, the rate of G(0)/G(1) plus S stages of PC-3 cells was significantly decreased in the high-dose ART group. The PC-3 cell was arrested in G(2)/M by ART. The rates of G(2)/M of the high-dose ART group and the medium-dose ART group were obviously higher than those of the blank control group and the cisplatin group (P<0.05). The levels of PSA in the three ART groups were significantly lower than that of the normal control group (P<0.05, P<0.01). In the ART groups, TEM showed that some vacuoles appeared in endochylema, cell polarity was enhanced, cell nucleus leaned to one side of the cell, and microvilli increased on the other side of the cell.
