Abstract
BACKGROUND Vasoactive drugs can reduce portal venous pressure and control variceal bleeding. However, few studies have explored the hemodynamic effects of terlipressin and high-dose octreotide in such patients. Our purpose was to evaluate the hemodynamic changes and safety of using terlipressin and high-dose octreotide in patients with decompensated liver cirrhosis. METHODS A multi-center randomized controlled trial was conducted. Cirrhotic patients with a history of variceal bleeding were included. Terlipressin or high-dose octreotide was administered during the procedure of measuring hepatic venous pressure gradient (HVPG). Hemodynamic parameters and symptoms were recorded. RESULTS A total of 88 patients were included. HVPG was significantly reduced at 10, 20, and 30 min after drug administration in the terlipressin group (16.3±6.4 vs. 14.7±5.9, 14.0±6.1, and 13.8±6.1, respectively, P<0.001) and the high-dose octreotide group (17.4±6.6 vs. 15.1±5.8, 15.3±6.2, and 16.1±6.0, respectively P<0.01). Decreased heart rate and increased mean arterial pressure were more often observed in the terlipressin group. The overall response rates were not significantly different between the groups (52.8% vs. 44.8%, P=0.524). The terlipressin group had significantly higher response rates at 30 min compared to the high-dose octreotide group in those with alcoholic liver cirrhosis [6/6 (100%) vs. 0/4 (0%), P=0.005]. The incidence of adverse drug events was rare and similar in the two groups. CONCLUSIONS Both terlipressin and high-dose octreotide were effective and safe for reducing HVPG. The pharmacodynamic effect of terlipressin persisted longer. The terlipressin group had higher response rates in those with alcoholic cirrhosis (trial number: NCT02119884).

Abstract
Background: COVID-19 is a public health emergency of international concern Its incidence rates and mortality are very high;however, so far, an effective drug treatment remains unknown Based on the role of convalescent plasma therapy in previously identified viral pneumonias, patients with severe COVID-19 have been given this therapy This systematic review and meta-analysis aimed to summarize the clinical evidence regarding the efficacy and safety of convalescent plasma therapy in the treatment of severe COVID-19 Methods: PubMed, Embase, Ovid, China Knowledge Network, China Biomedical, VIP Chinese Sci-tech Journal, Wanfang Database, and the International Clinical Trials Registry Platform were searched up to 21 June 2020, to identify clinical studies and registered trials on the use of convalescent plasma in the treatment of critically ill patients with COVID-19 Stata 13 0 was used to perform Meta-analysis All records were screened as per the protocol eligibility criteria Results: Nineteen clinical reports regarding convalescent plasma in the treatment of severe COVID-19 were included Through systematic analysis, convalescent plasma was found to yield some efficacy on severe COVID-19 and had almost no obvious adverse reactions Conclusion: Convalescent plasma therapy seems to yield some efficacy among patients with severe COVID-19 and almost no obvious adverse reactions were found However, at present, the clinical evidence is insufficient, and there is an urgent need for support from high-quality clinical trial data © 2020, Iranian Journal of Public Health All rights reserved

Journal of orthopaedic surgery and research. 2020;15(1):432
Abstract
BACKGROUND Plantar fasciopathy (PF) is a very common disease, affecting about 1/10 people in their lifetime. Platelet-rich plasma (PRP) had been demonstrated to be useful in achieving helpful effects for plantar fasciopathy. The purpose of this study was to compare the pain and functional outcomes between PRP and corticosteroid (CS) or placebo for plantar fasciopathy through meta-analysis and provide the best evidence. METHODS Literature was searched systematically to explore related studies that were published in Cochrane Library, PubMed, Embase, Medline, SpringerLink, OVID, and ClinicalTrials.gov . Articles regarding comparative research about the outcomes of PRP therapy and CS or placebo injection were selected. Data of pain and functional outcomes was extracted and imported into Reviewer Manager 5.3 to analyze. RESULTS Thirteen RCTs were included and analyzed. Analysis results showed significant superiority of PRP in outcome scores when compared with CS (VAS: MD = - 0.85, P < 0.0001, I(2) = 85%; AOFAS MD = 10.05, P < 0.0001, I(2) = 85%), whereas there is no statistical difference in well-designed double-blind trials (VAS: MD = 0.15, P = 0.72, I(2) = 1%; AOFAS MD = 2.71, P = 0.17, I(2) = 0%). In the comparison of the PRP and the placebo, the pooled mean difference was - 3.76 (P < 0.0001, 95% CI = - 4.34 to - 3.18). CONCLUSIONS No superiority of PRP had been found in well-designed double-blind studies, whereas it is implied that the outcomes of PRP are better than placebo based on available evidence.

Abstract
BACKGROUND To evaluate the efficacy and safety of Danggui Buxue Decoction for renal anemia when combined with western medicine treatment of anemia. METHODS Electronic searching Medline, Embase, Web of Science, Cochrane Library, Chinese BioMedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), WanFang data, Chinese Sci-tech periodical full-text database (VIP). Randomized controlled trials reported results of efficacy and safety of Danggui Buxue Decoction in combination with western medicine treatment of anemia for renal anemia. The "risk of bias assessment tool (Version 5.1.0)" of Cochrane Handbook was applied to assess the quality of included trials and RevMan 5.3 software was used for data analysis. RESULTS A total of 111 studies was retrieved, seven studies including 460 cases were included, the methodological quality of included trials was poor. The result of meta-analysis demonstrated that there was no difference in hemoglobin (Hb) [weighted mean differences (WMD) =-8.75, 95% confidence interval (CI): (-18.64, 1.13), P=0.08], whereas the subgroup analysis showed the difference was significant when the ratio of Radix Astragali to Radix Angelicae Sinensis was 5:1 [WMD =-16.27, 95% CI: (-28.73, -3.80), P=0.01], increase of Hb was more effective in experimental group than control group and the difference was not significant when the ratio of Radix Astragali to Radix Angelicae Sinensis was 5 not equal1 [WMD =-0.57, 95% CI: (-4.52, 3.39), P=0.78]. There were significant differences in red blood cell (RBC) [WMD =-0.49, 95% CI: (-0.69, -0.28), P<0.00001], hematocrit (HCT) [WMD =-1.92, 95% CI: (-3.15, -0.69), P=0.002] and clinical efficacy [odd ratio (OR) =0.30, 95% CI: (0.13, 0.69), P=0.004] between Danggui Buxue Decoction combination group and control group, the experimental group was better than control group. There was no adverse event reported in the experimental group. CONCLUSIONS Danggui Buxue Decoction in combination with conventional western medicine (CWM) for renal anemia might be superior to CWM alone and there was no adverse event in the experimental group, it might be more effective when the ratio of Radix Astragali to Radix Angelicae Sinensis was 5:1. However, the quality of included studies was not high, and less attention was paid to the safety, high quality randomized controlled trials are needed to further confirm the findings.
