Abstract
BACKGROUND Tranexamic acid (TXA) has been demonstrated to reduce blood loss following primary total knee and hip arthroplasty. This study aimed to compare the efficacy and safety of oral and intravenous tranexamic acid for primary total knee and hip arthroplasty. METHODS The PubMed, Embase, and Cochrane Library databases were searched for relevant studies published before June 20, 2019. Studies clearly reporting a comparison of oral and intravenous TXA were selected, and total blood loss (TBL), the decline in hemoglobin (DHB), deep vein thrombosis (DVT), intramuscular venous thrombosis (IVT), the length of hospital stay, and the transfusion rate were evaluated. The weighted mean differences and relative risks were calculated using a fixed-effects or random-effects model. RESULTS Ten studies involving 1140 (oral 557; intravenous 583) patients were included in this meta-analysis. There was no significant difference in terms of total blood loss, the decline in hemoglobin, the length of hospital stay, the incidence of DVT or IVT, or the transfusion rate between the oral and intravenous groups, and five studies reported that oral TXA was associated with a lower cost. CONCLUSION Our research suggests that compared with intravenous use of TXA, the oral approach has similar clinical outcomes and is less expensive for total joint replacement patients.

Abstract
BACKGROUND Oral tranexamic acid (TXA) has been demonstrated to reduce the blood loss in primary total knee and hip arthroplasty, but the optimal regimen of oral TXA administration is still unknown. This study aimed to find the best number of administrations of oral TXA for primary total knee and hip arthroplasty. METHODS The PubMed, Embase, and Cochrane Library databases were searched for relevant studies published before March 20, 2020. Studies clearly reporting a comparison of multiple administrations of oral TXA for total hip/knee replacement were included, and the total blood loss (TBL), intraoperative blood loss (IBL), decline in hemoglobin (DHB), deep vein thrombosis (DVT), intramuscular venous thrombosis (IVT), length of hospital stay (LOS), and transfusion rate were evaluated. The weighted mean differences and relative risks were calculated using a fixed effects or random effects model. RESULTS Nine studies involving 1678 patients were included in this meta-analysis (TXA 1363 (one administration, 201; two administrations, 496; three administrations, 215; four administrations, 336; five administrations, 115); placebo 315); the results show that compared with placebo groups, oral TXA could significantly reduce the TBL, IBL, DHB, LOS, and transfusion rate. In addition, the incidences of IVT and DVT were similar between the TXA and placebo groups. Moreover, two administrations of oral TXA significantly reduced the TBL and DHB compared with one administration, three administrations of oral TXA were better than two administrations, and four administrations of oral TXA were better than three administrations. CONCLUSION Our results suggested that oral TXA could significantly reduce the blood loss and the length of hospital stay but could not increase the incidence of DVT and IVT for total joint replacement patients; additionally, the effectiveness of oral TXA administration increased as the number of administrations increased.

Abstract
Objective: To investigate effect of continuous plasma filtration adsorption on treatment of severely burned patients with sepsis. Methods: In January 2014 to September 2017, 86 severely burned patients with sepsis, conforming to the study criteria, were admitted to our hospital and divided into into routine treatment group and continuous plasma filtration group according to the random number table method, with 43 patients in each group. Patients in routine treatment group were treated with routine treatment after admission. Patients in continuous plasma filtration group were treated with blood filter, blood purification machine, and plasma separator for continuous plasma filtration adsorption on the basis of the routine treatment group on the second day after admission. The course of treatment in the 2 groups was 7 d. The total effective treatment rate, changes of leukocyte count (WBC), usea nitrogen, serum creatinine, neutrophile CD64, procalcitonin, and C reactive protein (CRP) before and after treatment, and mortality on 28 days after treatment of patients in 2 groups were analyzed and compared. Results: (1) The total effective treatment rate of patients in continuous plasma filtration group was 88.37% (38/43), which was significantly higher than that of the routine treatment group [65.12% (28/43), chi(2)=6.515, P=0.018]. (2) After treatment, WBC, urea nitrogen, serum creatinine, neutrophils CD64, procalcitonin, and CRP of patients in continuous plasma filtration group were significantly lower those in routine treatment group (t=6.305, 4.420, 18.537, 13.435, 12.975, 14.234, P<0.05). WBC, urea nitrogen, serum creatinine, neutrophile CD64, procalcitonin, and CRP of patients in 2 groups after treatment were significantly lower than those before treatment (t=9.459, 9.130, 25.438, 35.467, 23.471, 23.601, 3.802, 5.662, 12.067, 25.694, 20.720, 12.437, P<0.05). (3) On 28 days after treatment, mortality of patients in continuous plasma filtration group was 6.98% (3/43), which was significantly lower than that in routine treatment group [25.58% (11/43)], chi(2)=5.460, P=0.023. Conclusions: Continuous plasma filtration adsorption is effective in treating severely burned patients with sepsis, which can alleviate inflammatory reaction mediated by inflammatory cytokine with good prognosis.
