Abstract
BACKGROUND The survival benefit of early placement of transjugular intrahepatic portosystemic shunts (TIPS) in patients with cirrhosis and acute variceal bleeding is controversial. We aimed to assess whether early TIPS improves survival in patients with advanced cirrhosis and acute variceal bleeding. METHODS We did an investigator-initiated, open-label, randomised controlled trial at an academic hospital in China. Consecutive patients with advanced cirrhosis (Child-Pugh class B or C) and acute variceal bleeding who had been treated with vasoactive drugs plus endoscopic therapy were randomly assigned (2:1) to receive either early TIPS (done within 72 h after initial endoscopy [early TIPS group]) or standard treatment (vasoactive drugs continued to day 5, followed by propranolol plus endoscopic band ligation for the prevention of rebleeding, with TIPS as rescue therapy when needed [control group]). Randomisation was done by web-based randomisation system using a Pocock and Simon's minimisation method with Child-Pugh class (B vs C) and presence or absence of active bleeding as adjustment factors. The primary outcome was transplantation-free survival, analysed in the intention-to-treat population, excluding individuals subsequently found to be ineligible for enrolment. This study is registered with ClinicalTrials.gov, number NCT01370161, and is completed. FINDINGS From June 26, 2011, to Sept 30, 2017, 373 patients were screened and 132 patients were randomly assigned to the early TIPS group (n=86) or to the control group (n=46). After exclusion of three individuals subsequently found to be ineligible for enrolment (two patients in the early TIPS group with non-cirrhotic portal hypertension or hepatocellular carcinoma, and one patient in the control group due to non-cirrhotic portal hypertension), 84 patients in the early TIPS group and 45 patients in the control group were included in the intention-to-treat population. 15 (18%) patients in the early TIPS group and 15 (33%) in the control group died; two (2%) patients in the early TIPS group and one (2%) in the control group underwent liver transplantation. Transplantation-free survival was higher in the early TIPS group than in the control group (hazard ratio 0.50, 95% CI 0.25-0.98; p=0.04). Transplantation-free survival at 6 weeks was 99% (95% CI 97-100) in the early TIPS group compared with 84% (75-96; absolute risk difference 15% [95% CI 5-48]; p=0.02) and at 1 year was 86% (79-94) in the early TIPS group versus 73% (62-88) in the control group (absolute risk difference 13% [95% CI 2-28]; p=0.046). There were no significant differences between the two groups in the incidence of hepatic hydrothorax (two [2%] of 84 patients in the early TIPS group vs one [2%] of 45 in the control group; p=0.96), spontaneous bacterial peritonitis (one [1%] vs three [7%]; p=0.12), hepatic encephalopathy (29 [35%] vs 16 [36%]; p=1.00), hepatorenal syndrome (four [5%] vs six [13%]; p=0.10), and hepatocellular carcinoma (four [5%] vs one [2%]; p=0.68). There was no significant difference in the number of patients who experienced other serious adverse events (ten [12%] vs 11 [24%]; p=0.07) or non-serious adverse events (21 [25%] vs 19 [42%]; p=0.05) between groups. INTERPRETATION Early TIPS with covered stents improved transplantation-free survival in selected patients with advanced cirrhosis and acute variceal bleeding and should therefore be preferred to the current standard of care.

Abstract
OBJECTIVE Explore the effect of the multifunctional airbag abdominal pressure belt on midwifery and on the prevention of postpartum hemorrhage. METHODS Select 363 natural delivery cases of hospitalized primiparae and divide them randomly into two groups. In the observation group, 182 primiparae used the multifunctional airbag abdominal pressure belt during the second and third stages of labor, whereas the control group of 181 did not use the belt. Delivery outcomes of the primiparae and their fetus were then observed. RESULTS The average duration for the second stage of labor, from head emergence to delivery, placenta delivery and postpartum hemorrhage were all shorter in the observation group (p < 0.01). There was no statistical difference in episiotomy rate, maternal signs 2 h postpartum, neonatal Apgar score and neonatal cord blood gas analysis (p > 0.05). No statistical difference was found in primipara signs and no fetal heart rate change of the primiparae under different internal pressures of the belt during the second stage of labor in the observation group (p > 0.05). CONCLUSION By closely monitoring and appropriately adjusting the internal pressure of the belt, the multifunctional airbag abdominal pressure belt can speed up the second and third stages of labor, prevent postpartum hemorrhage and promote natural delivery.

Abstract
BACKGROUND Hemostasis following transradial access (TRA) is usually achieved by mechanical compression. We investigated use of the QuikClot Radial hemostasis pad (Z-Medica) compared with the TR Band (Terumo Medical) to shorten hemostasis after TRA. METHODS Thirty patients undergoing TRA coronary angiography and/or percutaneous coronary intervention were randomized into three cohorts post TRA: 10 patients received mechanical compression with the TR Band, 10 patients received 30 min of compression with the QuikClot Radial pad, and 10 patients received 60 min of compression with the QuikClot Radial pad. Times to hemostasis and access-site complications were recorded. Radial artery patency was evaluated 1 hour after hemostasis by the reverse Barbeau's test. RESULTS There were no differences in patient characteristics, mean dose of heparin (7117 +/- 1054 IU), or mean activated clotting time value (210 +/- 50 sec) at the end of procedure among the three groups. Successful hemostasis was achieved in 100% of patients with both the 30-min and 60-min compression groups using the QuikClot pad. Hemostasis failure occurred in 50% of patients when the TR Band was initially weaned at the protocol-driven time (40 min after sheath removal). Mean compression time for hemostasis with the TR Band was 149.4 min compared with 30.7 min and 60.9 min for the 30-min and 60-min QuikClot groups, respectively. No radial artery occlusion occurred in any subject at the end of the study. CONCLUSIONS Use of the QuikClot Radial pad following TRA in this pilot trial significantly shortened hemostasis times when compared with the TR Band, with no increased complications noted.
