RESUMO
Osteoporotic vertebral compression fracture (OVCF) is the most common fragility fracture. Along with growth of population and increase of average life expectancy, the incidence of OVCF is rising constantly. As a common complication of OVCF, vertebral refracture not only possesses a high incidence, but also places a heavy physical, mental and financial burden on patients due to the pain and motor dysfunction. How to effectively prevent and treat the vertebral refracture has become a clinical focus at home and abroad. Vertebral refracture is a cumulative result of multiple factors, including patient factors as well as treatment factors. Accordingly, the authors summarize the related risk factors of vertebral refracture in OVCF patients in terms of systemic, local and therapeutic factors, so as to provide a certain reference for reducing the incidence of vertebral refracture and follow-up researches.
RESUMO
Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder, mainly manifested as recurrent abdominal pain, abdominal discomfort and/or changes of defecation habits and stool character, its pathogenesis has not been fully clarified. The pathophysiology is characterized by visceral hypersensitivity, abnormal intestinal motility, and so on. Abnormality of ion channels may be in involved in the pathophysiological mechanism of IBS. This article reviewed the progress in study on ion channels and pathogenesis of IBS.
RESUMO
In order to investigate the species and categorization of Gasterophilus in Ili horse.We analysised the COI gene of the identified Gasterophilus dominant species and constructed NJ phylogenetic tree in the study.The results showed that infection rate was 100％ in total of 16 775 the third phase Gasterophilus instar larvae.Four Gasterophilus species were identified,and showed serious mix infections.Dominant species were Gasterophilus nasalis,its relative dominance were 53.17％,and prefer to live in the cardia,others to irregular live in the pylorus of the horses.COI gene homology of GasterophiIus nasalis,Gasterophilus intestinalis,Gasterophilus pecorum,Gasterophilus haemorrhoidalis (GenBank Accession No.:GU265752.1,KR230402.1,KU578262.1,KT946620.1) were 99％,99％,99％ and 100％ respectively.Phylogenetic analysis results showed that the data were clustered with the Gasterophilus app.which publshed on the GenBank.G.intestinalis and G.haemorrhoidalis cluster together first,and then cluster with G.nasalis,at last all three kinds of Gasterophilus cluster with G.pecorum.When the COI gene is the target,in-group and out-group of the Gasterophilus can forms an independent evolutionary branch.This study provides useful parameters for the classification of Gasterophilus.
RESUMO
OBJECTIVE:To systematically evaluate the efficacy of mecobalamin,ganglioside,mixture of calcium and magne-sium,reduced glutathione,mixture of calcium and magnesium combined with reduced glutathione in the prevention of chronic neu-rotoxicity induced by oxaliplatin, and to provide evidence-based reference for clinic treatment. METHODS:Retrieved from PubMed,clinicltrials.gov and CJFD,randomized controlled trials (RCT) about efficacy of 5 interventions in the prevention of chronic neurotoxicity induced by oxaliplatin were collected,and network Meta-analysis were performed by using ADDIS 1.16.5 af-ter extracting data and evaluating quality. RESULTS:A total of 34 studies were included,involving 3 236 patients. 4 studies were three-arm studies,30 studies were two-arm studies,totally 42 arms. Compared with placebo,the incidence of CIPN by 5 interven-tions was significantly reduced. Mixture of calcium and magnesium combined with reduced glutathione was the most effective and the followed by mecobalamin,reduced glutathione,ganglioside and mixture of calcium and magnesium,however,there were no significant differences among 5 interventions(P>0.05). CONCLUSIONS:5 kinds of interventions are all effective in the preven-tion of chronic neurotoxicity induced by oxaliplatin. Mixture of calcium and magnesium combined with reduced glutathione is the most effective. Duo to the low quality of included studies,large-scale and high quality RCTs are required for further validation of the conclusions.
