Objectives: To investigate the effects of medium-and long-chain triacylglycerol (MLCT) on blood triglyceride (TG) in Chinese hypertriglyceridemic subjects. Methods: A double-blind controlled clinical trial was carried out, in which 112 subjects with hypertriglyceridemia were randomly divided into two dietary oil groups: (1) long-chain triacylglycerol (LCT) and (2) MLCT. All subjects were requested to ingest fixed energy and to continue their normal activity levels, and to consume LCT or MLCT oil at 25-30 g daily during the study period. Anthropometric measurements of body weight, body mass index (BMI), body fat, body fat percentage, waist and hip circumference (WC and HC), areas of subcutaneous and visceral fat by computed tomography scanning and blood biochemical markers were measured at the beginning and end of the study. Results: There were 50 and 51 subjects left in LCT and MLCT groups, respectively. There were no significant differences in daily intake of energy, protein, fat and carbohydrate, as well as the daily physical activity between the two groups during the study. After 8 weeks, MLCT group showed a significant decrease in body weight, BMI, WC, HC, ratio of WC and HC, body fat, body fat percentage and subcutaneous fat when compared with the initial values. The decrease in body weight, BMI, WC, body fat and subcutaneous and visceral fat was significantly greater in MLCT group than that in the LCT group. Furthermore, the serum concentrations of TG in MLCT group were significantly lower than those in the LCT group. Conclusions: Consumption of MLCT may reduce body weight, body fat and blood TG in hypertriglyceridemic subjects under an appropriate dietary regime.
ABSTRACT.Propofol is an extensively used intravenous anesthetic agent. The aim of the present study was to evaluate the effects of propofol on the behavior of human gastric cancer cells and the molecular mechanisms associated with this activity. The effects of propofol on proliferation and apoptosis in the SGC-7901 gastric cancer cell line were detected by an MTT assay and measurement of caspase-3 activity. The protein expression levels of matrix metalloproteinase-2 (MMP-2) were detected by western blotting. Reverse transcription-quantitative polymerase chain reaction was conducted to evaluate the effect of propofol treatment on microRNA (miR)-451 expression levels and an miR-451 precursor was used to evaluate whether miR-451 overexpression affects MMP-2 expression levels. In addition, the effect of miR-451 on propofol-induced antitumor activity was evaluated using anti-miR-451. Propofol significantly elevated miR-451 expression levels, inhibited SGC-7901 cell proliferation, and promoted apoptosis. Propofol also efficiently reduced MMP-2 protein expression levels. Furthermore, miR-451 overexpression reduced MMP-2 protein
OBJECTIVE: To identify risk factors influencing outcomes of bronchial arterial embolisation (BAE) in tuberculosis (TB) related haemoptysis.METHODS: A cohort of 207 patients underwent BAE for TB-related haemoptysis between March 2014 and March 2018. The clinical data
were reviewed. Follow-up ranged from 24 to 1749 days.RESULTS: Immediate haemostasis rate was 94.2%; aggressive pleural thickening (PT) was found to be a risk factor for haemoptysis (P = 0.000, OR 22.52). Cumulative recurrence-free rates were respectively 98.5%, 94.8%, 88.7%,
79.9%, 68.5%, 65.7% and 62.7% for 1, 3, 6, 12, 24, 36 and 48 months. Respectively 8 and 15 patients recovered from pneumonectomy and re-BAE. However, five patients required a third BAE. The Cox regression analysis indicated that aggressive PT (P = 0.000), diabetes mellitus (DM) (P
= 0.018) and pulmonary fungal infection (PFI) (P = 0.001) were independent risk factors for recurrence. The death rate following BAE was 9.2%; aggressive PT was a risk factor (P = 0.000, OR 8.14).CONCLUSION: BAE is effective for TB-related haemoptysis in most cases.
Aggressive PT, DM and PFI are independent risk factors influencing the prognosis following BAE. PFI and DM should be well managed, while proper surgery should be considered for aggressive PT.
