Résumé
It is the hotspot that studying the interplay and mechanism between intestinal flora metabolites and diseases.Deoxycholic acid, one of the intestinal flora metabolites, is one of the most abundant secondary bile acids in human intestinal tract, which is corelated with many diseases, while the mechanisms remain unclear.The imbalance of deoxycholic acid is connected with the intestinal flora disorder and high fat diet, which could result in several immunoreaction and inflammatory reaction.In this review, the interaction between deoxycholic acid and digestive diseases in children, such as non-alcoholic fatty liver disease, inflammatory bowel disease and irritable bowel syndrome, is discussed to explore their related mechanism, so as to clarify the direction of further study on the influence of intestinal microbiota metabolites deoxycholic acid on the human body.
Résumé
Objective To investigate the correlation between ipsilateral prominent posterior cerebral artery laterality (PCAL) and white matter hyperintensities (WMHs) in patients with severe internal carotid artery (ICA) stenosis. Methods From April 2016 to December 2017, patients with unilateral ICA stenosis≥70% (including occlusion) and contralateral ICA stenosis <50% or no stenosis admitted to the Department of Neurology, Liaoning Provincial People's Hospital were enrolled. According to the presence or absence of PCAL on the ipsilateral side of ICA stenosis, they were divided into positive group and negative group, and the severity of WMHs was compared between the 2 groups. The patients were grouped according to the severity of overall WMHs and deep WMHs (DWMHs) and periventricular WMHs (PWMHs) on the ipsilateral side of ICA stenosis. Multivariate logistic regression analysis was used to determine the independently relevant factors of WMHs. Results A total of 131 patients were enrolled, 65 of them (49.62% ) had ipsilateral PCAL positive. The proportion of severe DWMHs in this group was significantly lower than that in the ipsilateral PCAL negative group (38.46% vs. 59.09% ; χ2 =5.578, P=0.018 ). Multivariate logistic regression analysis showed that advanced age (odds ratio [ OR] 2.196, 95% confidence interval [ CI] 1.278-3.773; P=0.004), hypertension (OR 3.279, 95% CI 1.107-9.709; P=0.032), and high systolic blood pressure (OR 1.027, 95% CI 1.002-1.053; P=0.031) were independently associated with severe overall WMHs; advanced age (OR 1.957, 95% CI 1.141-3.358; P=0.015) and hypertension (OR 4.739, 95% CI 1.570-14.286; P=0.006) were independently correlated with ipsilateral severe DWMHs, ipsilateral PCAL (OR 0.340, 95% CI 0.135-0.856; P=0.022 ) was independently correlated with ipsilateral mild DWMHs; advanced age (OR 1.805, 95% CI 1.175-2.775; P=0.007) and high systolic blood pressure (OR 1.030, 95% CI 1.007-1.053; P=0.010) were independently correlated with ipsilateral severe PWMHs. Conclusion Ipsilateral PCAL is an independent protective factor for ipsilateral DWMHs in patients with severe ICA stenosis.
Résumé
Objective To compare the therapeutic efficacy of reteplase(r-PA) and alteplase(t-PA) in the high risk patients with pulmonary embolism during a pulmonary artery catheter broken bolt in the interventional treatment,and to evaluate the clinical safety.Methods 54 high risk patients were selected as the research subjects,and they were randomly divided into treatment group(24 patients) and control group(30 patients).Patients in both two groups were given general treatment,low molecular heparin sodium anticoagulation therapy.Besides,the control group was given local perfusion thrombolysis enzyme treatment.While the treatment group was given local perfusion at enzyme thrombolysis treatment.Results Two-way Chi-square test results showed that before treatment,there were no significant differences in HR,RF,PaO2,PaCO2 and SaO2 between the two groups(all P>0.05).After 3-day treatment,in the treatment group,HR[(83.39±14.25)times/min],RF[(17.80±1.65)times/min],PaO2[(87.59±7.34)mmHg],PaCO2[(37.60±7.62)mmHg],SaO2[(97.29±6.72)%] in the treatment group group,which in the control group were (97.7±15.51)times/min,(20.49±1.68)times/min,(81.53±6.42)mmHg,(35.69±4.57)mmHg,(93.91±3.27)%,the differences between the two groups were statistically significant(t=8.01,7.33,6.32,all P<0.05).After three days therapy,the total effective rate was 86.67% in the treatment group,which was significantly higher than 75.00% in the control group (x2=1.21,P=0.55).After thrombolysis treatment,there was no significant difference between the treatment group and control group in hemorrhage rate(x2=2.24,P=0.53),which were 13.33% and 12.50%,respectively.Besides,the hemorrhage patients were all got effectively treated and their condition was significantly improved,and none of them occurred severe bleeding during the observation periods in the two groups.Conclusion Local perfusion reteplase therapy in high-risk patients with PE through the pulmonary artery catheter broken bolt in the interventional treatment is safe and is worthy of clinical promotion.
