Abstract
Objective: The mobilization and collection of sufficient autologous peripheral blood stem cells (APBSCs) are important for the fast and sustained reconstruction of hematopoietic function after autologous transplantation. This study aims to evaluate the mobilization effect and safety of thrombopoietin (TPO) combined with chemotherapy + G-CSF for APBSCs in patients with refractory/relapsed non-Hodgkin's lymphoma. Methods: A total of 78 patients were included in the present study. After receiving mobilization chemotherapy, all patients were randomly divided into two groups: TPO group (n=40), patients were given subcutaneous injection of rhTPO + G-CSF, and control group (n=38), patients were given subcutaneous injection of G-CSF. The primary endpoint was the total number of obtained CD34+ cells. The secondary endpoints were the mononuclear cell count, the proportion of target and minimum mobilization, the engraftment time of neutrophils and platelets after APBSCT, the number of platelet and red blood cell infusions, the incidence of infectious fever and fever duration, and TPO-related side effects in patients. Results: TPO participation significantly increased the total CD34+ cell count. A higher proportion of patients in the TPO group achieved the minimum and target CD34+ cells, when compared to the control group. TPO-related adverse events were not observed in either of these groups. In addition, there were no significant differences in engraftment time, the number of platelet and red blood cell transfusions, the incidence of infectious fever, and fever duration between these two groups. Conclusion: TPO combined with chemotherapy + G-CSF can safely and effectively enhance the mobilization effect for APBSCs in patients with refractory/relapsed non-Hodgkin's lymphoma.

Abstract
BACKGROUND AND AIM Acute variceal bleeding (AVB) is life-threatening. We aimed to systematically review the current evidence regarding the efficacy and safety of terlipressin for AVB in liver cirrhosis. METHODS We searched the PubMed, EMBASE, and Cochrane Library databases. The reference list was also hand-searched. Using a random-effect model, we combined the data obtained according to the different time points when the events developed. Odds ratio (OR) and weighted mean difference (WMD) were calculated. Quality of evidence was evaluated by the GRADE methodology. RESULTS Thirty randomized controlled trials with 3344 patients were included. Compared with no vasoactive drug, terlipressin significantly improved the control of bleeding within 48 hours (OR = 2.94, P = .0008) and decreased the in-hospital mortality (OR = 0.31, P = .008). Compared with somatostatin, terlipressin had a significantly higher risk of complications (OR = 2.44, P = .04). Compared with octreotide, terlipressin had a significantly inferior control of bleeding within 24 hours (OR = 0.37, P = .007). Compared with vasopressin, terlipressin had a significantly lower risk of complications (OR = 0.15, P = .02). Compared with terlipressin combined with endoscopic variceal ligation, terlipressin alone had significantly higher 5-day treatment failure (OR = 14.46, P = .01) and transfusion requirements within 49 to 120 hours (WMD = 1.20, P = .002). No outcome was significantly different between terlipressin and sclerotherapy. Compared with balloon tamponade, terlipressin significantly decreased the 30-day rebleeding (OR = 0.05, P = .001) and transfusion requirements (WMD = -2.70, P = .02). Quality of evidence was very low to moderate. CONCLUSION Our findings were in accordance with the current recommendations regarding terlipressin for the treatment of AVB in cirrhosis. However, due to low quality of evidence, further studies are recommended.

Abstract
BACKGROUND Hip osteoarthritis is one of the most prevalent musculoskeletal degenerative diseases in elderly. Total hip arthroplasty (THA) is the most effective surgical treatment for end stage hip osteoarthritis. Tranexamic acid (TA) is a potent drug to reduce surgical blood loss in surgery, therefore, as a potential drug for application in THA. OBJECTIVES To identify the combined efficacy of TA administration in THA. A meta-analysis including 25 randomized controlled trials was conducted for generating synthesized effects. METHODS This meta-analysis followed the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines for reporting systematic reviews and meta-analysis. A total of 25 Randomized controlled trials (RCTs) were included for meta-analysis. RESULTS The pooled results illustrated that total blood loss, intraoperative blood loss, postoperative blood loss, hemoglobin drop, transfusion rate, and average hospital stay were significantly lower than controls (standardized mean difference or odds ratio (OR) (95%CI): -0.87, (-1.13,-0.61), -0.68, (-0.96,-0.39), -1.41, (-2.24,-0.59), -1.11, (-1.63,-0.58), 0.28, (0.20,-0.38), -0.17, (-0.49,0.14), P < .05, respectively). Moreover, TA acts efficiently without increasing risk of thromboembolic events with OR = 1.14, 95%CI = 0.50-2.62, P = .75. Subgroup analysis indicated no statistically significant differences between a higher dose of topical TA (≥2 g or 15 mg/kg) or a lower dose (<2 g or 15 mg/kg). CONCLUSION The findings indicated that TA is clinically effective and safe in patients receiving total hip arthroplasty.

Abstract
BACKGROUND Simultaneous bilateral total knee arthroplasty (TKA) can lead to greater blood loss and higher risk of venous thromboembolism. The effectiveness and safety of tranexamic acid (TXA) in simultaneous bilateral TKAs have not been clearly defined. We presumed that a fixed dose of TXA may be a preferable alternative for ease of administration in patients undergoing simultaneous bilateral TKAs. METHODS We prospectively randomized 120 primary simultaneous bilateral TKAs to a fixed dose of TXA or equivalent volume of normal saline intravenously. The primary outcome measure was total blood loss. The secondary outcome measures were blood transfusion rate, transfusion units, intraoperative blood loss, drainage volumes, hidden blood loss, maximum decline of hemoglobin, and postoperative suprapatellar girth increment. RESULTS There were statistically significant lower total blood loss, blood transfusion rate, drainage volumes, transfusion units, and maximum decline of hemoglobin in the TXA group than in the control group (P < .05), without increasing incidence of asymptomatic and symptomatic venous thromboembolism. However, TXA did not significantly reduce the hidden blood loss (P = .123). No differences were observed in suprapatellar girth increments between both groups on postoperative day 5 and week 6 (P = .251 and .299). CONCLUSION Fixed dose of TXA for patients undergoing simultaneous bilateral TKAs was effective and safe in reducing total blood loss and allogeneic blood transfusion needs without any additional thromboembolic risk. However, TXA administered intravenously did not significantly reduce the hidden blood loss.

Abstract
OBJECTIVE To determine the value of the use of a pneumatic tourniquet in total knee arthroplasty. METHODS Sixty patients were prospectively randomized into 2 groups, one group underwent total knee replacement with a tourniquet (n = 30) and one without (n = 30). Operating time, blood loss, postoperative mean morphine requirement, swelling, ecchymosis, earlier straight-leg raising and postoperative knee flexion were measured in both groups. RESULTS There was no significant difference in the total blood loss between the 2 groups although the intraoperative blood loss was significantly greater in those without a tourniquet. The mean morphine requirement, postoperative swelling, scope of ecchymosis, earlier straight-leg raising and postoperative knee flexion in the patients that had surgery without a tourniquet were significantly better than those with a tourniquet. CONCLUSION Knee arthroplasty operation with the use of a tourniquet has only small benefits on the total blood loss, but hinder in patients' early postoperative rehabilitation exercises.
