Abstract
BACKGROUND This study aimed to compare the efficacy and safety of oral tranexamic acid (TXA) with intravenous (IV) TXA in reducing perioperative blood loss in total-knee arthroplasty (TKA) and total-hip arthroplasty (THA). METHODS PubMed, Web of Science, Embase, and Cochrane Library were fully searched for relevant studies. Studies comparing the efficacy and safety of oral TXA with IV TXA in TKA and THA were included in this research. Odds ratio (OR) or risk difference (RD) was applied to compare dichotomous variables, while mean difference (MD) was used to compare continues variables. RESULTS A total of 7 studies (5 randomized controlled trials and 2 retrospective studies) were included into this study. As for patients undergoing TKA or THA, there were no obvious differences between oral TXA group and IV TXA group in hemoglobin (Hb) drop (MD = 0.06, 95% confidence interval [CI] = -0.01 to 0.13, P = .09), transfusion rate (OR = 0.78, 95% CI = 0.54-1.13, P = .19), total blood loss (MD = 16.31, 95% CI = -69.85 to 102.46, P = .71), total Hb loss (MD = 5.18, 95% CI = -12.65 to 23.02, P = .57), length of hospital stay (MD = -0.06, 95% CI = -0.30 to 0.18, P = .63), drain out (MD = 21.04, 95% CI = -15.81 to 57.88, P = .26), incidence of deep vein deep vein thrombosis (RD = 0.00, 95% CI = -0.01 to 0.01, P = .82) or pulmonary embolism (RD = 0.00, 95% CI = -0.01 to 0.01, P = .91). The sample size of this study was small and several included studies were with relatively low quality. CONCLUSION Oral TXA is equivalent to IV TXA in reducing perioperative blood loss and should be recommended in TKA and THA. More high-quality studies are needed to elucidate this issue.

Abstract
BACKGROUND Outcomes of minimally invasive surgery (MIS) versus conventional craniotomy (CC) for patients with spontaneous supratentorial intracerebral hemorrhage(SICH) have not been previously compared. We reviewed the current evidence regarding the safety and efficacy of MIS as compared with conventional craniotomy, in patients with SICH. METHODS We conducted a meta-analysis of studies that comparing MIS and CC in patients with computed tomography confirmed SICH, published from January 2000 to April 2018 in Medline, Embase, and Cochrane Controlled Trials Register (CCTR) based on PRISMA inclusion and exclusion criteria. Binary outcomes comparisons between MIS and CC were described using odds ratios (ORs). RESULTS Five randomized controlled trials (RCTs) and nine prospective controlled studies (non-RCTs) met the included criteria, involving 2466 patients. There was statistically significant difference in mortality rates between MIS and CC (OR, 0.76; 95% confidence interval [CI], 0.60-0.97). MIS associated with lower rates of complications in rebleeding (OR, 0.42; 95% CI, 0.28-0.64), and higher rates of good recovery compared with CC (OR, 2.27; 95% CI, 1.34-3.83). CONCLUSIONS Patients with SICH may benefit more from MIS than CC. Our study could help clinicians to optimize treatment strategies in SICH.

Abstract
OBJECTIVE To compare the effect of endoscopic-assisted low temperature plasma (ELTP) and electric planer (EP) on the treatment of adenoid hypertrophy. Methods: We searched China National Knowledge Infrastructure (CNKI), Wanfang Database, Weipu Database, Chinese Biomedical Literature (CMB), PubMed, Embase, Cochrane Database, and collected the randomized controlled studies regarding the effect of ELTP and EP on the treatment of adenoid hypertrophy from January 2007 to June 2016. Methodologies were used to evaluate the included studies, and Meta-analysis was performed by Revman 5.2. Results: Thirteen studies including 1 448 patients fulfilled the study requirement. Seven hundred and twenty-two patients were treated with ELTP, and 726 patients were treated with EP. The Meta-analysis showed: compared with EP, ELTP could improve the cure rare (OR=3.19, 95% CI 1.42 to 7.15, P=0.005), reduce the blood loss during surgery (MD=-20.35, 95% CI -20.84 to -19.87, P<0.001), shorten the operation time (MD=-15.71, 95% CI -18.06 to -12.17, P<0.001), and reduce the incidence of complications (OR=0.13, 95% CI 0.06 to 0.30, P<0.001), while there was no difference between the 2 groups in the postoperative residual rate of adenoid, postoperative hemorrhage rate and the rate of torus tubarius injury. Conclusion: Comparing with EP, ELTP shows more advantages in the adenoidectomy.

Abstract
BACKGROUND Acute normovolaemic haemodilution (ANH) is an efficacious blood conservation strategy aiming at avoiding allogeneic blood transfusion. ANH was shown to increase the potency of vecuronium, atracurium, and rocuronium. The aim of our study was to investigate whether cisatracurium potency is altered with ANH. METHODS Using the Relaxometer mechanomyograph, we compared cisatracurium dose-response relationship and time course of action in 60 patients randomly allocated to the ANH or control groups. Patients in each group were randomly allocated to receive one of three cisatracurium doses (30, 40, 50 microg kg(-1)) followed by a second supplemental dose to reach a total of 100 microg kg(-1). RESULTS ANH did not result in a significant shift in cisatracurium log dose-probit dose-response curve. There was no significant difference in mean (95% confidence intervals) ED(50), ED(90), and ED(95) (effective doses required for 50, 90, and 95% first twitch depression) between the ANH group [29. 5 (27-32), 50. 4 (47. 4-53. 4), 58. 7 (55. 3-62) microg kg(-1)] and the control group [28. 2 (25. 3-31), 47. 6 (44. 9-50. 3), 55. 3 (52. 5-58. 1) microg kg(-1)], whereas there was no difference in mean (SD) Dur(25) and Dur(0. 8) (time until 25% first twitch and 0. 8 train-of-four ratio recoveries) between the ANH group [40. 8 (5. 9), 64. 7 (8. 4) min] and the control group [42. 2 (7. 6), 66. 5 (10. 7) min]. CONCLUSIONS Our results demonstrated that unlike other previously reported neuromuscular blocking drugs, ANH did not alter cisatracurium potency. Thus, cisatracurium would be the neuromuscular blocking drug of choice in patients who undergo surgery with ANH, as no dose adjustments are required.
