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.
Comparative efficacy of platelet-rich plasma applied in myringoplasty: A systematic review and meta-analysis
PloS one. 2021;16(1):e0245968
BACKGROUND Tympanic membrane (TM) perforation is quite common in the clinical setting. Chronic TM perforations require surgical treatments such as myringoplasty. Currently, platelet-rich plasma (PRP) is a novel, effective substance that is increasingly utilized for TM perforation repair. This study aims to evaluate the effectiveness of PRP in the application of TM perforation repair. METHODS A systematic search was conducted to screen the Medline, Embase, Cochrane, Scopus and Web of Science databases up to July 2020. Studies were identified in accordance with the selection criteria by two coauthors independently. Data regarding the healing and hearing outcomes were pooled and analyzed via Review Manager version 5.3 and STATA version 12.0 software. Odds ratio (OR) was utilized to compare the closure rate. Furthermore, the results of hearing improvements and incidence of complications were also compared to evaluate the effectiveness of PRP. RESULTS A total of eight studies with 455 participants were eligible according to the selection criteria. Compared to conventional surgery, the OR of closure was 2.70 (95% CI: 1.27 to 5.76, P = 0.01, I2 = 0%) in randomized controlled trial (RCT) subgroup and 6.18 (95% CI: 2.22 to 17.25, P = 0.0005, I2 = 0) in non-RCT subgroup. The overall OR of closure was 3.69 (95% CI: 2.02 to 6.74, P<0.0001, I2 = 0%), suggesting a significant effect on the healing of TM perforation. Between preoperative and postoperative hearing results, there is no statistical difference between the PRP and the control groups. Additionally, the use of PRP resulted in a lower incidence of complication than the use of conventional approaches. CONCLUSION The application of PRP during the TM surgeries can enhance the closure rate, provide similar hearing improvements and decrease the incidence of postoperative complications. Given these advantages, PRP can be considered an effective treatment for TM regeneration.
Efficacy and safety of tranexamic acid in aneurysmal subarachnoid hemorrhage: A meta-analysis of randomized controlled trials
The American journal of emergency medicine. 2021;50:646-653
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.

Pediatrics international : official journal of the Japan Pediatric Society. 2021
BACKGROUND We aimed to assess the efficacy of different initial intravenous immunoglobulin (IVIG) regimens in Kawasaki disease (KD) patients to find more cost-effective therapy options. METHODS A multicentre, open-label, blind-endpoint randomized controlled trial was conducted from January 2014 to December 2015. KD Patients within 10 days of illness were randomly assigned to receive different IVIG regimens (Group A, 2 g/kg once; Group B, 1 g/kg for 2 consecutive days; Group C, 1 g/kg once) and aspirin 30mg/kg/d. Primary outcomes included hours to defervescence and development of coronary artery lesions (CAL) during the study period. Major secondary outcomes included total fever days, total dose of IVIG, changes of laboratory data, length of stay, and hospitalization expenses. (ClinicalTrials.gov: NCT02439996). RESULTS A total of 404 patients underwent randomization. No difference was found in the outcomes of defervescence among three groups at 6, 12, 24, and 36 hours after completion of initial IVIG infusion. There were no differences in the incidence of CAL during the study period (at week 2, month 1, month 3, and month 6 of illness), changes of laboratory data, total fever days and length of stay. Group C patients had the lowest total dose of IVIG (mean: 1.2 vs 2.2 vs 2.1 g/kg; P<0.001) and hospitalization expenses (mean: 8443.8 vs 10798.4 vs 11011.4 RMB; P<0.001) than other two groups. CONCLUSIONS A single dose of 1g/kg IVIG is a low-cost treatment with the same efficacy as 2 g/kg IVIG and can be an option for the initial therapy of KD patients.

American journal of translational research. 2021;13(4):2955-2961
OBJECTIVE This study aimed to explore the role of primary nursing in patients with hypertensive intracerebral hemorrhage (HICH) undergoing minimally invasive surgery. METHODS We randomly assigned 106 patients with HICH treated in our hospital to receive routine nursing (54 cases, group A) or primary nursing in addition to routine nursing (52 cases, group B). The scores of negative emotions, incidence of complications, quality of life, and prognosis of all patients were recorded. RESULTS The score of negative emotions and the incidence of complications were lower in group B than in group A (P < 0.05). The scores of quality of life and prognosis were higher in group B than in group A (P < 0.05). CONCLUSION Primary nursing intervention can improve the prognosis and postoperative quality of life of patients with HICH undergoing minimally invasive surgery.

Perioperative blood transfusion adversely affects prognosis after resection of lung cancer: a systematic review and a meta-analysis
BMC Surgery. 2014;14((1):):34.
BACKGROUND It is speculated that blood transfusion may induce adverse consequences after cancer surgery due to immunosuppression. This study was intended to assess the impact of perioperative blood transfusion on the prognosis of patients who underwent lung cancer resection. METHODS Eligible studies were identified through a computerized literature search. The pooled relative risk ratio (RR) with 95% confidence interval (CI) was calculated using Review Manager 5.1 Software. RESULTS Eighteen studies with a total of 5915 participants were included for this meta-analysis. Pooled analysis showed that perioperative blood transfusion was associated with worse overall survival (RR: 1.25, 95% CI: 1.13-1.38; P <0.001) and recurrence-free survival (RR: 1.42, 95% CI: 1.20-1.67; P <0.001) in patients with resected lung cancer. CONCLUSIONS Perioperative blood transfusion appears be associated with a worse prognosis in patients undergoing lung cancer resection. These data highlight the importance of minimizing blood transfusion during surgery.

Chung-Hua Fu Chan Ko Tsa Chih [Chinese Journal of Obstetrics & Gynecology]. 1998;33((4):):206-8.
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.
