Objective To evaluate the quality of evidence of systematic reviews or meta-analyses regarding outcomes in nursing field in China using the Grade system, so as to get known of the status of the quality of evidence and promote the application of the evaluation of the quality of evidence of systematic reviews. Methods The quality of evidence regarding the included outcomes was input, extracted and qualitatively graded, using GRADEpro 3.6 software. Then, we carefully analyzed and elaborated the factors of downgrading and upgrading that affects the quality of evidence in the process of evaluation. Results 53 systematic reviews or meta-analyses involving 188 outcomes were identified and evaluated. The results showed that high, moderate, low and very low levels of quality of evidence were 2.7%, 27.1%, 51.1%, and 19.1%, respectively; and low-level quality of evidence accounted for the most. Conclusion The quality of evidence produced by systematic reviews or meta-analyses in nursing field in China is poor and urgently needs improvement. The reviewers should abide by the methodological standards in the process of making systematic reviews or meta-analyses. The quality of evidence in terms of each outcome should be evaluated and fully reported.
ObjectiveTo explore the expression and clinical significance of plasma soluble podoplanin (sPDPN) in patients with colorectal cancer (CRC). MethodsTCGA-READ, TCGA-COAD datasets were obtained to compare expression level of PDPN mRNA in CRC tissues and adjacent tissues, and to explore the relationship between expression of PDPN mRNA and the prognosis of CRC patients. A total of 85 CRC patients (CRC group) underwent surgery in the Second Affiliated Hospital of Xuzhou Medical University from November 2020 to December 2022, and 100 healthy volunteers from the hospital were collected as a control group to detect the expression levels of plasma sPDPN of the two groups, and exploring the relationship between sPDPN expression and the clinicopathological characteristics of the CRC patients. The ROC curves of sPNPD, sugar antigen 199 (CA199) and carcinoembryonic antigen (CEA) were drawn simultaneously, and the predictive value of sPDPN for CRC was explored by logistic regression model. ResultsThe results of TCGA dataset showed that expression level of PDPN mRNA was upregulated in CRC tissues compared with adjacent tissues/paired adjacent tissues (P<0.05), and patients with high expression level of PDPN mRNA had better prognosis than low expression patients (P=0.045). The expression level of sPDPN was (3.50±1.77) ng/mL in CRC group, which was higher than (1.95±0.46) ng/mL of the control group (P<0.01). The expression level of sPDPN was higher in CRC patients at Ⅲ+Ⅳ clinical stage (P=0.026) and N1–2 stage (P=0.049). Compared with CA199 and CEA, sPDPN had the highest area uncer curve value of 0.882 (0.832, 0.932), and was an risk predictor of CRC [OR=14.339, 95%CI (5.649, 36.396), P<0.001]. ConclusionThe sPDPN is highly expressed in the plasma of CRC patients and has a certain clinical utility for diagnosis of CRC, and evaluation of clinical staging and lymph node metastasis.
ObjectiveTo systematically review the interventional effects of Simiao Yong'an decoction on atherosclerosis animal models.MethodsDatabase including CNKI, WanFang Data, VIP, PubMed, The Cochrane Library, and Web of Science were searched to collect animal experiments on atherosclerosis model intervention by Simiao Yong’an decoction from inception to October 2020. Two reviewers independently screened the literature, extracted data, and used the SYRCLE animal experiment bias risk assessment tool to evaluate risk bias of included studies, and then used RevMan 5.4.1 software for meta-analysis.ResultsA total of 14 animal experiments were included. The results of meta-analysis showed that compared with the blank model group, the Simiao Yong’an decoction group could reduce the aortic plaque area (SMD=−2.04, 95%CI −3.35 to −0.74), the ratio of aortic plaque to lumen area (SMD=−1.72, 95%CI −2.48 to −0.97), total cholesterol level (SMD=−0.97, 95 %CI −1.72 to −0.22), triglyceride level (SMD=−1.21, 95%CI −1.82 to −0.60), low-density lipoprotein cholesterol level (SMD=−1.82, 95%CI −3.12 to −1.53), tumor necrosis factor-α level (SMD=−3.36, 95%CI −4.21 to −2.52), monocyte chemotactic factor-1 level (SMD=−2.98, 95%CI −4.60 to −1.35) and C-reactive protein level (SMD=−0.60, 95%CI −1.08 to −0.11); however, in the high-density lipoprotein cholesterol level (SMD=0.66, 95%CI −0.10 to 1.42) and the level of interleukin 1 (SMD=−1.41, 95%CI −4.11 to 1.30), the differences were not statistically significant.ConclusionsThe existing evidence shows that the intervention of Simiao Yong’an decoction in the atherosclerosis model can reduce the aortic plaque area and the ratio of the aortic plaque to the lumen area, reduce total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels, and reduce tumor necrosis factor-α, monocyte chemotactic factor-1, and C-reactive protein levels. Due to limited quality of included studies, more high quality studies are required to verify the above conclusions.
