Abstract
OBJECTIVE The optimal dose and efficacy of tranexamic acid (TXA) and epsilon-aminocaproic acid (EACA) in total knee arthroplasty (TKA) were under controversial, and we aimed to make comparisons between different doses of TXA and EACA in intravenous (IV) or intra-articular (IA) applications in patients undergoing TKA. METHODS This network meta-analysis was guided by the Priority Reporting Initiative for Systematic Assessment and Meta-Analysis (PRISMA). According to the administrations of antifibrinolytic agents, patients in eligible studies were divided into three subgroups: (i) IA applications of TXA and EACA; (ii) IV applications (g) of TXA and EACA; (iii) IV applications (mg/kg) of TXA and EACA. Total blood loss (TBL), hemoglobin (HB) drops and transfusion rates were the primary outcomes, while drainage volume, pulmonary embolism (PE) or deep vein thrombosis (DVT) risk were the secondary outcomes. A multivariate Bayesian random-effects model was adopted in the network analysis. RESULTS A total of 38 eligible trials with different regimens were assessed. Overall inconsistency and heterogeneity were acceptable. Taking all primary outcomes into account, 1.0-3.0 g TXA were most effective in IA applications, 1-6 g TXA and 10-14 g EACA were most effective in IV applications (g), while 30 mg/kg TXA and 150 mg/kg EACA were most effective in IV applications (mg/kg). None of the regimens showed increasing risk for pulmonary embolism (PE) or deep vein thrombosis (DVT) compared with placebo. CONCLUSION 0 g IA TXA, 1.0 g IV TXA or 10.0 g IV EACA, as well as 30 mg/kg IV TXA or 150 mg/kg IV EACA were most effective and enough to control bleeding for patients after TKA. TXA was at least 5 times more potent than EACA.

Abstract
OBJECTIVE To evaluate the safety and efficacy of using ergometrine maleate injection combined with oxytocin injection, with oxytocin injection as the control, to prevent postpartum hemorrhage after vaginal delivery. METHODS A total of 305 cases who underwent vaginal delivery between December 2018 and November 2019 in 16 hospitals across China were enrolled and included in the full analysis set (FAS) and the safety analysis set (SS). Among the 299 subjects who completed the trial, 277 were included in the per protocol set (PPS). The subjects were randomly assigned by 1∶1 ratio to two groups, 152 cases in Group A, the experimental group receiving oxytocin injection plus ergometrine injection, and 153 cases in Group B, the control group, receiving oxytocin injection. The difference in total bleeding volume at 2 h, 6 h and 24 h postpartum in the two groups was documented and compared. Other measures were also compared between the two groups, including the proportion of additional use of uterotonics and hemostatic drugs or other hemostatic measures 2 h and 24 h postpartum, the proportion of subjects needing blood transfusion, the time of placenta retention, proportion of subjects with prolonged hospital stay due to uterine asthenia, the vital signs, lab test indicators and the incidence of adverse reactions in the two groups. RESULTS The total bleeding volume at 2 h, 6 h and 24 h after delivery was significantly lower in the experimental group (P<0.05). There was no significant difference between the two groups in the proportion of additional use of uterotonics and hemostatic drugs or other hemostatic measures 2 h and 24 h postpartum, the proportion of subjects needing blood transfusion and the time of placenta retention, heart rate, respiration, lab test indicators, or the incidence of adverse reaction (P>0.05). CONCLUSION Ergometrine maleate injection showed evident therapeutic efficacy in preventing hemorrhage after vaginal delivery, causing fewer adverse reactions and ensuring greater safety, and therefore, presenting promising prospects for clinical application.

Abstract
OBJECTIVES We aimed to evaluate the optimal regimen, efficacy and safety of tranexamic acid (TXA) and aminocaproic acid (EACA) for patients after total hip arthroplasty (THA). METHODS The network meta-analysis was guided by the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guideline. The outcomes were total blood loss, transfusion rates, hemoglobin (HB) drop, and risk for pulmonary embolism (PE) or deep vein thrombosis (DVT). Subgroup analyses were performed among most effective regimens to determine the influences of timing and number of doses. RESULTS A total of 56 eligible RCTs with different regimens were assessed. For reducing total blood loss, all high doses of TXA and EACA except high dose of intra-articular (IA) TXA, as well as medium dose of combination of intravenous and intra-articular (combined IV/IA) TXA were most effective. All high doses of TXA, as well as medium dose of combined IV/IA TXA did not show inferiority in reducing transfusion rates and HB drop compared with other regimens. No regimens showed higher risk for PE or DVT compared with placebo, and no statistical differences were seen among most effective regimens in subgroup analyses. CONCLUSIONS As effective as high doses of EACA and TXA, medium dose (20-40 mg/kg or 1.5-3.0 g) of combined IV/IA TXA was enough to control bleeding for patients after THA without increasing risk for PE/DVT. TXA was at least 5 times more potent than EACA. Timing and number of doses had few influences on blood conserving efficacy. LEVEL OF EVIDENCE Level I.

Abstract
Objective: To compare oxytocin combined with ergometrine with oxytocin alone in terms of primary prophylaxis for postpartum hemorrhage (PPH) at the time of cesarean section (CS). Methods: This was a multicenter double-blind randomized controlled interventional study comparing ergometrine combined with oxytocin and oxytocin alone administered at CS. From December 2018 to November 2019, a total of 298 parturients were enrolled in 16 hospitals nationwide. They were randomly divided into experimental group (ergometrine intra-myometrial injection following oxytocin intravenously; 148 cases) and control group (oxytocin intra-myometrial injection following oxytocin intravenously; 150 cases) according to 1∶1 random allocation. The following indexes were compared between the two groups: (1) main index: blood loss 2 hours (h) after delivery; (2) secondary indicators: postpartum blood loss at 6 h and 24 h, placental retention time, incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution; (3) safety indicators: nausea, vomiting, dizziness and other adverse reactions, and blood pressure at each time point of administration. Results: (1) The blood loss at 2 h after delivery in the experimental group [(402±18) ml] was less than that in the control group [(505±18) ml], and the difference was statistically significant (P<0.05). (2) The blood loss at 6 h and 24 h after delivery in the experimental group were less than those in the control group, and the differences were statistically significant (all P<0.05). There were no significant differences between the two groups in the incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution (all P>0.05). (3) Adverse reactions occurred in 2 cases (1.4%, 2/148) in the experimental group and 1 case (0.7%, 1/150) in the control group. There was no significant difference between the two groups (P>0.05). The systolic blood pressure within 2.0 h and diastolic blood pressure within 1.5 h of drug administration in the experimental group were higher than those in the control group, and the differences were statistically significant (P<0.05), but the blood pressure of the two groups were in the normal range. Conclusion: The use of ergometrine injection in CS could reduce the amount of PPH, which is safe and feasible.

Abstract
INTRODUCTION Tranexamic acid, as a traditional hemostatic agent, is commonly used to treat or prevent excessive blood loss. However, the role of tranexamic acid in promoting good clinical outcomes and reducing mortality and risk of adverse events during the treatment of aneurysmal subarachnoid hemorrhage remains unclear. METHODS In strict accordance with the inclusion and exclusion criteria, Cochrane Library, Embase, Web of Science, and PubMed databases were assessed for randomized controlled trials (published between 1980 and 2021). Data were analyzed using STATA 16.0 and RevMan 5.3. In addition, the fixed-effects model (M-H method) and effect size (risk difference; RD) were used as a pooled measure to combine data. We also performed a post hoc sensitivity analysis and subgroup analysis to evaluate each outcome with low heterogeneity. RESULTS A meta-analysis revealed that although tranexamic acid was related to less rebleeding (RD = -0.06; 95% CI [-0.09, -0.03]; P = 0.0006), there is evidence that it has no an effect on good clinical outcomes or mortality (RD = -0.01; 95% CI [-0.05, 0.02]; P = 0.51; RD = 0.00; 95% CI [-0.03, 0.04]; P = 0.91). Tranexamic acid was associated with increased hydrocephalus (RD = 0.04; 95% CI [0.01, 0.08]; P = 0.02) and seizure (RD = 0.04; 95% CI [0.00, 0.08]; P = 0.05). The incidence of thromboembolic complications or delayed cerebral ischemia was not different in the two groups (RD = -0.01; 95% CI [-0.04, 0.03]; P = 0.62; RD = 0.00; 95% CI [-0.03, 0.03]; P = 0.96), and significant drug-related overall adverse events were identified (RD = 0.02; 95% CI [0.00, 0.04]; P = 0.03). CONCLUSIONS These findings indicate that the routine use of tranexamic acid is not suggested for patients with aneurysmal subarachnoid hemorrhage.

Abstract
OBJECTIVE To study the efficacy of iron supplementation during pregnancy and its influences on the outcome of pregnancy. METHODS A total of 369 pregnant women were enrolled in this study. According to the hemoglbin levels at recruitment, there were 2 groups: preventive (Hb > or = 110 g/L) and treatment (Hb < 110 g/L) groups. In the preventive group, women entered the study from 20-24 gestational weeks and were randomly assigned to materna treatment (n = 96) who took materna 1 tablet daily or control group (n = 95) who took no other supplementation. In the treatment groups, women less than 36 gestational weeks were accepted. They were randomly divided as materna (n = 93) 1 tablet/d, ferrous sulfate 0.3 g tid/d (n = 50) or Ferroids 1 tablet/d (n = 35) groups. Both Hb and serum ferritin concentrations were determined at admission and immediately after delivery. In some cases serum ferritin in the umbilical vein were measured as well. Hemoglobin levels were examined every 4 weeks during the observational period. RESULTS In the preventive groups, maternal serum ferritin levels after materna treatment were significantly higher than that before treatment and the control group (P < 0.05). As for the anemia women, compared the serum ferritin concentration, materna treatment had significantly higher levels than that at admission (P < 0.05), and also higher than that in the ferrous sulfate or ferroids tratment groups (P < 0.05). The s-ferritin in the umbilical vein had no correlation with the paired maternal levels. There were no significant differences in the pregnancy outcomes among all the groups. CONCLUSION Materna can increase the iron storage and effectively improve the iron deficiency during pregnancy, and has no impact on the prgnancy outcomes.
