ABSTRACT
Objective:To compare the therapeutic effect of polysaccharide iron complex capsule and Shengxuening tablet on renal anemia in maintenance hemodialysis (MHD) patients.Methods:Patients who received MHD treatment from April to June 2016 in our dialysis center and met the criteria for iron deficiency anemia were block-randomly divided into two groups: the polysaccharide-iron complex group and the Shengxuening group. Blood routine, iron metabolism biomarkers and biochemical exams were measured before treatment and at the 1st, 2nd and 3rd months after treatment, and the incidence of adverse reactions were recorded. The compliance rate of the two groups was observed and compared, and the block-randomized-statistical methods were used to compare the clinical data of the two groups before and after treatment, and cost-benefit analysis was also conducted.Results:Thirty patients in each group completed follow-up. After three months of treatment, the blood routine and iron metabolism indicators of the two groups were improved. Compared with the Shengxuening group, the polysaccharide iron complex group had higher therapeutic efficiency, and the levels of hemoglobin, transferrin saturation and serum ferritin were higher, and lower use of recombinant human erythropoietin ( P<0.05). The other indexes such as red blood cell (RBC), hematocrit (HCT) levels and the effective rate of anemia correction, the effective rate of iron therapy, the effective rate of iron therapy between the two groups were similar. Cost-benefit analysis suggested that the use of polysaccharide iron complexes to treat anemia has lower costs and higher benefits ( P<0.05). Conclusions:Polysaccharide iron complex capsule can better correct anemia and improve iron metabolism, and has low cost-effectiveness, which can effectively reduce medical insurance expenditure. It is a good iron supplementing method in addition to intravenous iron supplement.
ABSTRACT
Nonalcoholic fatty liver disease(NAFLD)is a kind of metabolic and stress-related liver damage closely related with insulin resistance and inherited susceptibility. Its incidence is increasing recently in China. Liver biopsy is the gold standard for the diagnosis of NAFLD,but which is an invasive procedure with certain risks. Therefore,finding a simple and accurate diagnostic method is an eager task,and searching of non-invasive biomarkers for diagnosis of NAFLD has become a hot spot of study. This article reviewed the progress in studies on biomarkers for diagnosis of NAFLD.
ABSTRACT
Objective To investigate the correlations between miRNA and mRNA ( the regulatory effects of miRNA) in a rat model of trinitro-benzene-sulfonic acid (TNBS)/ethanol induced ulcerative colitis ( UC) .Methods TNBS and ethanol were used to induce the development of UC in rats .After the modeling procedure and oral administration of normal saline ( NS) for 14 days, rats from the control and model groups were dissected to collect the samples of colonic mucosa .General and histological evaluations were performed to validate the modeling of UC .The expression of miRNA was profiled using miRNA microarray .The target miRNAs that were closely related to the pathogenesis of UC were selected out according to the results of mi -croarray and related literatures .RT-PCR was performed to verify the differentially expressed miRNAs .The mirWalk database was used to predict the target genes of miRNAs .In order to verify whether the predicted results were in accordance with the actual results , the microarray technology was used for mRNA expression profiling .The genes that showed interactions with those miRNAs were screened out .The David database was used for gene annotation .An interaction net between miRNA and mRNA was formed .Results General and histological manifestation of colon tissue samples from the model group were in accordance with the features of UC.Sixty-eight miRNAs were identified to be differentially expressed in rats from the model group and the control group (fold change>2, P7).Six candidate miRNAs were selected as hav-ing close relations to the pathogenesis of UC referring to reported literatures , the expression of which was checked and verified by real-time polymerase chain reaction (PCR).Compared with the control group, 4 miRNAs (miR-146a-5p, miR-146b-5p, miR-126a-3p and miR-21-5p) were up-regulated (P<0.01, P<0.05) and 2 miRNAs (miR-200b-3p and miR-145-5p) were down-regulated (P<0.01) in rats with TNBS/ethanol induced UC.Four mRNAs (IL-6, Ccl5, Mapk3 and Smad7) that interacted with the 6 miRNAs were identified based on the results of target gene prediction of the above 6 miRNAs and gene expression pro-filing.The David database was used to annotate the interactions for elucidating their significance in the path -ogenesis of UC .Conclusion A miRNA can regulate many signaling pathways and a signaling pathway can also be regulated by many miRNAs .Therefore , simply inhibiting certain pathways may not radically stop the process of inflammation .Studying the functions of miRNAs and elucidating the correlations between miRNA and mRNA might fundamentally inhibit the development of UC .
ABSTRACT
[Objective] Through a meta-analysis to compare the effectiveness and safety of traditional Chinese medicine and western medicine in the treat-ment of chronic atrophic gastritis(CAG) with dysplasia . [Methods] Randomized clinical trials(RCTs) which compared traditional Chinese medicine and western medicine for chronic atrophic gastritis with dysplasia in PubMed, Cochrane library, WanFang and CNKI were searched. The patients which were analyzed were divided into two groups: western medicine and traditional Chinese medicine.Statistical heterogeneity between trials was evaluated by RevMan5.0. Heterogeneity of the included articles was tested and used to select proper effective model for calculation.Publication bias was investigated through visual inspection of funnel plots and Egger's regression model.[Results] 6 RCTs including 632 patients were analyzed. The total odd ratios(OR) of clinical symptoms,gastroscope symptoms,pathological symptoms by traditional Chinese medicine were higher than western medicine, the OR values were 3.40(95%CI:2.18~5.31,P<0.01),4.14(95%CI:2.37~7.20,P<0.01),2.94(95%CI:1.77~4.90,P<0.01),3.71(95%CI:2.29~6.02,P<0.01),4.41(95%CI:2.75~7.07,P<0.01),5.21 (95%CI:3.65~7.43,P<0.01). Inspection of the funnel plots for al outcome measures did not reveal evidence of publication bias( P=0.81, 0.41, 0.29, 0.88, 0.44, 0.82, respectively).[Conclusions] The treatment of chronic atrophic gastritis with dysplasia by traditional Chinese medicine can improve the excel ent response rate, overal response rate of clinical symptoms,gastroscope symptoms,pathological symptoms better than its purely western medicine treatment efficacy.
ABSTRACT
Objective To observe the effect of angiotensin-converting enzyme inhibitors (ACEI) on anemia and erythropoietin (EPO) requirements in maintenance hemodialysis patients. Methods Ninety maintenance hemodialysis patients with hypertension and anemia were divided into 2 groups by random digits table, observation group (45 cases, using ACEI as antihypertensive treatment), control group [45 cases,using calcium channel blocker (CCB) as antihypertensive treatment]. The follow-up period after starting ACEI or CCB therapy was one year. The hemoglobin concentration, serum EPO, EPO requirements were compared after 0, 2, 4, 6, 8, 10, 12 months' treatment. Results In response to ACEI, the mean hemoglobin value in observation group decreased progressively, reaching statistical significance after 6 months, and it had significant difference compared with that in control group [6 months: (94.21±9.20) g/Lvs. (105.55±9.16) g/L,12 months: (95.90±6.75) g/L vs. (105.81±4.45) g/L,P <0.05]. The EPO requirements experienced a progressive increase in observation group and reached statistical significance after 8 months, compared with those in control group [8 months: ( 10 090.75±1918.35) U/week vs. (7010.32±1600.15) U/week, 12 months: (11 586.39±2009.76) U/week vs. (7068.48±1615.35) U/week,P<0.05].Serum erythropoietin concentration remained stable during the study in two groups. Conclusion ACEI can worsen anemia and reduce the efficacy of EPO in maintenance hemodialysis patients.
