The effectiveness and safety of plaster splint and splints for distal radius fractures: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: To assess the efficacy and safety of plaster splint vs splints in the treatment of distal radius fractures (DRFs). METHODS: For a more comprehensive collection of original study, we mainly searched 9 electronic databases including the PubMed, Web of Science, EMBASE, Cochrane Library, Cochrane Central Register of Controlled Trials (CENTRAL), Clinical Trials.gov, the Chinese National Knowledge Infrastructure Database (CNKI), Wanfang Database, and VIP Database. The retrieval date of all databases is from the establishment to January 2019. In the aspect of assessing the quality of original research methodology, we mainly rely on the Cochrane risk bias assessment tool and GRADE assessment method. Revman 5.3 is used for statistical analysis. RESULTS: A total of 8 studies involving 717 participants were included. The results showed that effective rate (RR = 0.99, 95%CI 0.91 to 1.07, P = .83), reduction rate (RR = 1.00, 95%CI 0.93 to 1.07, P = .98), and complication rate of the plaster splint had no significant difference with the splint. In addition, for the excellent rate of treatment, subgroup analysis based on the included studies found that when the intervention period was 4 weeks, the plaster splint was better than the splint, and when the intervention period was more than 4 weeks, there was no significant difference between them. CONCLUSIONS: There is no sufficient evidence that plaster splint is superior to splint. However, according to current evidence, plaster splint is more effective than splint when the intervention period is shorter (4 weeks), and its advantage disappears when the intervention period is longer (> 4 weeks). It should be noted that the results of this study were influenced by the sample size and the quality of the included studies. More high-quality and well-controlled RCTs are needed to draw better conclusions in further study.

The efficacy, safety, and cost benefits of splints for fractures of the distal radius in children: A systematic review and meta-analysis protocol.

BACKGROUND: Distal radius fractures (DRFs) is one of the most common bone injuries in children, which may lead to deformity and other complications if the treatment is not prompt or appropriate. Splints external fixation is a common conservative treatment for such fractures. Therefore, we conducted a systematic review and meta-analysis to explore the efficacy, safety and cost benefits of splints in the treatment of DRFs in children. METHODS: PubMed, Web of Science, Embase, Cochrane Library, Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov, Chinese National Knowledge Infrastructure Database (CNKI), Wanfang Database, and VIP Database were searched for eligible randomized controlled trials (RCTs). The methodological quality of the included studies and the level of evidence for results were assessed, respectively, using the risk bias assessment tool of Cochrane and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method. Statistical analysis was conducted with Revman 5.3. RESULTS: This study will analyze and integrate the existing evidence for effectiveness, safety and cost benefits of splints on DRFs in children. CONCLUSION: The conclusion of this study will provide evidence to effectiveness, safety and cost benefits of splints on DRFs in children, which can further guide the selection of appropriate interventions.

[Inhibitory effect against the gastric carcinoma cell growth by the combination of the survivin antisense oligonucleotide and P53 gene].

OBJECTIVE: To investigate the inhibitory effect and mechanism against the growth of human gastric carcinoma cell line HS-746T by the combination of the survivin antisense oligonucleotide (ASODN) and P53 gene and its mechanism. METHODS: Gastric carcinoma cell line HS-746T was treated by P53 gene and survivin antisense oligonucleotide was designed. There were four regimen groups treated by different agents:ASODN alone, P53 gene alone and the combination of ASODN and P53 gene, blank control. Cell proliferative ability and cell growth were determined by cells counting and MTT. The expression of survivin mRNA and protein was detected by RT-PCR and Western blot respectively. Cell apoptotic index was detected by TUNEL. RESULTS: ASODN alone, P53 alone and the combination of ASODN and P53 could inhibit not only the growth of gastric carcinoma cell, but also down-regulate the survivin mRNA and protein expression. The inhibitory effect was stronger, and the apoptosis index was higher in the combined transfection group than those in the other two single transfection groups. CONCLUSION: The combination of survivin ASODN and P53 gene is more efficient to inhibit cell growth and induce apoptosis than that of agent alone.
