Objective To investigate the relationship between waist-to-height ratio and metabolic syndrome,in order to identify the optimal cut-off point of waist-to-height ratio for predicting metabolic syndrome.Methods In this cross-sectional study,we recruited 343 people who received physical examination in First Hospital of Quanzhou between January 2012 and June 2014,and collected the information of their waist circumference,height,weight,blood pressure,laboratory test results (including fasting blood glucose,2-hour glucose after oral glucose tolerance test,triglyceride,high-density lipoprotein cholesterol) and visceral fat area assessed by computed tomography.Then a receiver operating characteristic (ROC) curve analysis was used to estimate the optimal cut-off points of waist-to-height ratio for the prediction of metabolic syndrome.Results Among the 343 people,there were 195 metabolic syndrome patients,the prevalence rate was 56.8％,which was 70.2％ in men (127/181) and 42.0％ in women (68/162).In ROC curve analysis,the area under the curve of waist-to-height ratio for the prediction of metabolic syndrome was 0.664 for men,and 0.673 for women.The optimal cut-off point of waist-to-height ratio for predicting metabolic syndrome was 0.543 0 (sensitivity 88.2％,specificity 44.4％) for men,and 0.568 3 (sensitivity 86.8％,specificity 46.8％).Conclusion The optimal cut-off point of waist-to-height ratio for predicting metabolic syndrome in Quanzhou population is 0.543 0 for men and 0.568 3 for women.

OBJECTIVETo review the studies investigating the increased risk of lung cancer in patients with idiopathic pulmonary fibrosis (IPF).

DATA SOURCESData cited in this review were obtained mainly from PubMed and Medline from 1999 to 2013 and highly regarded older publications were also included.

STUDY SELECTIONWe identified, retrieved and reviewed the information on the frequency, risk factors, anatomical features, histological types, clinical manifestations, computed tomography findings and underlying mechanisms of lung cancer in IPF patients.

RESULTSThe prevalence rates of lung cancer in patients with IPF (4.8% to 48%) are much higher than patients without IPF (2.0% to 6.4%). The risk factors for lung cancer in IPF include smoking, male gender, and age. Lung cancers often occur in the peripheral lung zones where fibrotic changes are predominant. Adenocarcinoma and squamous cell carcinoma are the most common types of lung cancer in patients with IPF. Radiologic features of these patients include peripherally located, ill-defined mass mimicking air-space disease. The underlying mechanisms of the development of lung cancer in patients with IPF have not been fully understood, but may include the inflammatory response, epithelial injury and/or abnormalities, aberrant fibroblast proliferation, epigenetic and genetic changes, reduced cell-to-cell communication, and activation of specific signaling pathways.

CONCLUSIONSThese findings suggest that IPF is associated with increased lung cancer risk. It is necessary to raise the awareness of lung cancer risk in IPF patients among physicians and patients.

This study was aimed to investigate the effects of high-dose strictosamide injection on cardiovascular sys-tem of anesthetized beagle dogs and to examine the inhibition of strictosamide on ion channels in vitro. Indexes such as changes of systolic blood pressure (Sys), diastolic blood pressure (Dia), mean blood pressure (MBP), heart rate (HR), PR, QRS, QT, QTcb and QTcv at different time points before and after strictosamide injection in dogs were monitored by the polygraph system. The inhibition of strictosamide at different concentrations on hERG potassium channel in CHO-hERG cells and Nav1.5 sodium channel in HEK-293-Nav1.5 cells were measured by whole-cell patch-clamp method. The results showed that compared with the blank control group, Sys, Dia, MBP and HR were obviously declined 15 min after medication in the strictosamide (60, 18 mg·kg-1) group and the vehicle-control group (containing tween-80) (P < 0.05). After medication, all indexes were recovered. Compared to the vehicle-control group, there were no significant differences at different time points in each medication groups. Compared with the blank control group and before medication, the QT interval, QTcb and QTcv were significantly prolonged 15 min af-ter medication in the strictosamide (60, 18, 6 mg·kg-1) group and the vehicle-control group (P< 0.05). When medi-cation stopped, indexes were recovered at certain level. Compared with the vehicle-control group, there were no sig-nificant differences of QT interval, QTcb and QTcv of each medication group at different time points (P> 0.05). The inhibition of strictosamide on hERG potassium channel and Nav1.5 sodium channel were weak with IC50 values of 560.8 μM and > 900 μM, respectively, which were far greater than the positive controls. It was concluded that sin-gle, high-dose intravenous injection of strictosamide may lead to a lower blood pressure, a slower heart rate and a prolongation on the QT interval in beagle dogs, which returned to basal levels when medication stopped. It was spec-ulated that the reduction of blood pressure and the slowing of heart rate were related to tween-80 contained in the vehicle control group. No significant inhibitory effects were detected on hERG potassium channel and Nav1.5 sodium channel in vitro, which suggested that other mechanisms may be involved in strictosamide-induced QT interval pro-longation in animals.
