End-stage renal disease is a late complication of chronic kidney disease (CKD) and one of the leading causes of high mortality worldwide. Over the years, the impacts of gut microbiota and their associated uremic toxins on kidney diseases through the intricate “gut-kidney axis” have been extensively studied. However, translation of microbiome-related omics results into specific mechanisms is still a significant challenge. In this paper, we review the interaction between gut microbiome and blood purification, as well as the current microbiota-based therapies in CKD. Additionally, the current sequencing technologies and progresses in the gut microbiome research are also discussed.
Childhood obesity is a global public health problem that seriously affects the normal growth and development of children. In recent years, a large number of studies have pointed out that the intestinal microbiome is closely related to childhood obesity, and the treatment strategies targeting the intestinal microbiome have a certain improvement effect on childhood obesity. This article elaborates on the establishment and development of intestinal microbiome, intestinal microbiome characteristics, the mechanisms of intestinal microbiome involvement in the occurrence and development of childhood obesity, and potential intervention strategies, so as to provide more ideas for basic and clinical research on childhood obesity.
【Abstract】 Objective To analyze the lung pathological features of type A H1N1 influenza and respiratory failure. Methods The data of imaging and aspiration lung biopsy of five patients with type A H1N1 influenza and respiratory filure since October 2009 were retrospectively analyzed. Results Common clinical manifestations of patients with type A H1N1 influenza and respiratory failure were rapid progress of illness after common cold-like symptoms with high fever, dyspnea, severe hypoxemia, large amounts of bloody sputum, wet rales over both lungs, and with other organs involved or even septic shock. Early lung pathological features were inflammatory exudate in alveoli and lung interstitium, infiltration of inflammatory cells, and extensive hemorrhage. Middle and late pathological features were hyperplasia of alveolar epithelial,disconnection of alveolar septa, replaced of alveolar spaces by fibrosis. Conclusions The pathology of patients with type A H1N1 influenza and respiratory failure is similiar with ARDS. Development of treatment strategies targeted to pathological characteristics of ARDS caused by type A H1N1 influenza is of greatsignificance for effective and timely treatment.
ObjectiveTo investigate therapeutic strategy of acute pulmonary embolism. MethodsClinical data of 48 patients with acute pulmonary embolism who were treated in Affiliated Hospital of North Sichuan Medical College form January 2009 to May 2014 were analyzed retrospectively. ResultsOf the 48 cases, 14 cases of low risk (low risk group) were treated with anticoagulation, 24 cases of middle risk (middle risk group) were treated with anticoagulation and systematic thrombolysis or interventional therapy (local thrombolysis after thrombus fragmentation or thrombolytic catheter placement in pulmonary artery), 10 cases of high risk (high risk group) were treated with anticoagulation and interventional therapy. In low risk group, 12 cases (85.7%) were cured and 2 cases (14.3%) were markedly effective, and total effective rate was 100%. In middle risk group, 16 cases (66.7%) were cured and 8 cases (33.3%) were markedly effective, and total effective rate was 100%. In high risk group, 1 case died, 3 cases were cured, 2 cases were markedly effective, and 4 cases were better, and the total effective ratio was 9/10. All cases suffered from no complication such as hemorrhage of cerebral and digestive system. Forty-eight cases were followed up for 3-12 months, with a median time of 8 months. During the follow-up period, there was no complication occurred such as dyspnea, pulmonary embolism, placement change of filter net, and thrombosis. ConclusionsCorresponding therapeutic strategy would be taken according to risk stratification of the acute pulmonary embolism.
ObjectiveTo summarize and explore the individualized surgical treatment strategy and prognosis of anomalous aortic origin of coronary artery (AAOCA). MethodsThe clinical data of children with AAOCA admitted to Shanghai Children's Medical Center from March 2018 to August 2021 were retrospectively analyzed. ResultsA total of 17 children were enrolled, including 13 males and 4 females, with a median age of 88 (44, 138) months and a median weight of 25 (18, 29) kg. All patients received operations. The methods of coronary artery management included coronary artery decapitation in 9 patients, coronary artery transplantation in 5 patients and coronary artery perforation in 3 patients. One patient with severe cardiac insufficiency (left ventricular ejection fraction 15%) received mechanical circulatory assistance after the operation for 12 days. No death occurred in the early postoperative period, the average ICU stay time was 4.3±3.0 d, and the total hospital stay was 14.4±6.1 d. All the children received regular anticoagulation therapy for 3 months after discharge. The median follow-up time was 15 (13, 24) months. All patients received regular anticoagulation therapy for 3 months after discharge. No clinical symptoms such as chest pain and syncope occurred again. The cardiac function grade was significantly improved compared with that before operation. Imaging examination showed that the coronary artery blood flow on the operation side was unobstructed, and no restenosis occurred. ConclusionAAOCA is easy to induce myocardial ischemia and even sudden cardiac death. Once diagnosed, operation should be carried out as soon as possible. According to the anatomic characteristics of coronary artery, the early effect of individualized surgery is satisfactory, and the symptoms of the children are significantly improved and the cardiac function recovers well in the mid-term follow-up.
ObjectiveTo compare the outcomes following emergency surgery or conservative treatment for patients with acute type A aortic intramural hematoma (IMH).MethodsClinical data of consecutive patients diagnosed with acute type A aortic IMH in our hospital from September 2014 to December 2018 were retrospectively analyzed. The patients who met our surgical indications received surgery (an operation group) and other patients received strict conservative treatment (a conservative treatment group).ResultsFinally 127 patients were enrolled, including 112 males and 15 females with an average age of 53.6±13.0 years. Of 127 patients, 85 (66.9%) patients accepted emergency surgery and 42 (33.1%) patients accepted strict conservative treatment. There was no difference between the two groups in early mortality or complications (P＞0.05). The 5-year survival rate was 90.4% in the operation group and 74.3% in the conservative treatment group (P=0.010). A maximum aortic diameter in the ascending aorta and aortic arch≥45 mm and maximum thickness of IMH in the same section≥8 mm were risk factors for IMH-related death in patients undergoing conservative treatment (P＜0.001).ConclusionThe mortality associated with emergency surgery for patients with acute type A aortic IMH is satisfactory. In clinical centers with well-established surgical techniques and postoperative management, emergency surgical treatment may provide a better outcome than conservative treatment for patients with acute type A aortic IMH.
ObjectivesTo systematically review the influence of single-stent versus double-stent strategy for coronary bifurcation lesions prognosis.MethodsPubMed, The Cochrane Library, EMbase, Web of Science, CBM, WanFang Data, VIP and CNKI databases were searched online to collect randomized controlled trials (RCTs) of single-stent versus double-stent strategy for coronary bifurcation lesions from inception to March, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 23 RCTs involving 7 391 patients were included. The results of meta-analysis showed that: compared to the double-stent strategy, the single-stent strategy significantly reduced the myocardial infarction rate (RR=0.61, 95%CI 0.50 to 0.73, P<0.001). There were no significant differences between two groups in all cause mortality, cardiac mortality, main adverse coronary event (MACE), target lesion revascularization (TLR) and stent thrombosis. The results of subgroup analysis showed that: single-stent strategy for coronary bifurcation lesions was associated with lower all-cause mortality at five-years follow-up (RR=0.59, 95%CI 0.40 to 0.88,P=0.01).ConclusionsCurrent evidence shows that single-stent strategy for coronary bifurcation lesions could reduce the myocardial infarction rate and five-year mortality compared to double-stent strategy. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
