ABSTRACT
BACKGROUND: Acupuncture is a common treatment for urinary retention after spinal cord injury. It has been widely used in the clinical treatment of urinary retention after spinal cord injury due to its small side effects and simple operation. However, there is a lack of evidence-based medicine. OBJECTIVE: To examine the effectiveness of acupuncture for urinary retention in patients with spinal cord injury by a systematic review and Meta-analysis of randomized controlled trials (RCTs). METHODS: A computer-based online retrieval of CBM, CNKI, WanFang, Cochrane Library, PubMed, EMBASE, and Web of Science databases was performed. The keywords were "spinal cord injury, neurogenic bladder, acupuncture" in English and Chinese, respectively. RCTs concerning acupuncture or acupuncture combined with conventional therapy were identified and a Meta-analysis was conducted on RevMan 5.3 software. RESULTS AND CONCLUSION: Nine RCTs involving 632 participants were included. In terms of urodynamic changes, compared with the control group,acupuncture was more effective in improving the residual urine volume[mean difference(MD)=-144.26,95% confidence interval(CI)(-252.15,-36.37),P=0.009]and maximum cystometric capacity[MD=35.69,95%CI(3.15,68.22),P=0.03].However,there were no significant differences between two groups for average daily number of urination[MD=-1.66,95% CI(-3.40,0.07),P=0.06].Concerning total effective rate,acupuncture was more effective than control group[RR=1.24,95%CI(1.11,1.37),P<0.0001].To conclude,compared with the conventional therapy, acupuncture is more effective in improving residual urine volume, maximum cystometric capacity and total effective rate for urinary retention in patients with spinal cord injury.
ABSTRACT
Objective To evaluate the effect of high intensity interval training(HIIT)on type 2 diabetes mellitus(T2DM). Methods Published articles from the earliest date available to September the first,2016 were recalled from PubMed,Em-base,Cochrane Library,EBSCO,Web of Science,CNKI and CBM Database.Two reviewers selected indepen-dently the randomized controlled trials(RCTs)about HIIT for patients with T2DM,and extracted data indepen-dently and analyzed with RevMan 5.3. Results Eight trials that represented 275 participants were evaluated.HIIT could significantly improve glycated hemo-globin(SMD=-0.72,95%CI-1.39~-0.04,P=0.04)and body mass index(MD=-0.60,95%CI-1.03~-0.18,P=0.005)more than the control group,but no difference was found in the levels of fasting blood-glucose,fasting in-sulin,insulin resistance,and indexes of blood fat,body mass,body fat mass and waist circumference(P>0.05). Conclusion There is no evidence showed that HIIT is more effective on blood glucose,blood fat and body composition in the patients with T2DM,which needs further research.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship of CD44 expression or glycosylation and hepatocellular carcinoma (HCC) metastasis.</p><p><b>METHODS</b>IHC, Quantum dots detection, RT-PCR, Western blot, Cellular immune fluorescence and MS-PCR were used to identify CD44 expression in HCC samples and a series of human HCC cell lines with different metastatic potentials. Lectin array was used to reveal the relationship of CD44v6 glycosylation and human HCC metastasis.</p><p><b>RESULTS</b>Immunohistochemistry analysis showed that CD44v6 was mainly distributed on the cell membrane, while CD44S immunoreactivity was prominently in the cytoplasm, CD44v3 and CD44v4/5 were in cytoplasm on membrane. Among CD44S and those CD44 variants, only the expression of CD44v6 was higher in metastasis HCC samples as compared to that in non-metastasis group (x²=8.828, P less than 0.05). This result was also re-confirmed by the result of Quantum dots (t = 2.392, P < 0.05) and serum detection (t = 2.56, P < 0.05). We found completely methylation of CD44v6 gene in Hep3B and incomplete methylation in MHCC97H and MHCC97L cell lines with metastatic potentials. The lectin affinity assay indicated that lectin MAL, SNA and WGA showed more affinity to MHCC97H and MHCC97Lcell lines than that of the non-metastatic Hep3B cell lines.</p><p><b>CONCLUSIONS</b>CD44v6 over-expression presents a positive correlation with HCC metastatic potential, which may be associated with DNA methylation level in promoter sequence. The increasing sialic acid modified glycan of CD44v6 might be related to HCC metastatic ability.</p>
