Abstract
INTRODUCTION Tranexamic acid reduces blood loss and allogeneic transfusion requirements in various surgical procedures. The role of tranexamic acid during cytoreductive procedures in advanced ovarian cancer is not clear. MATERIAL AND METHODS This was a single center randomized, controlled, three-armed clinical trial. A total of 150 ovarian cancer patients undergoing cytoreductive surgery were recruited and assigned to three groups (n = 50/group): the control group (normal saline), low-dose group (10 mg/kg bolus + 1 mg/kg continuous infusion of tranexamic acid), and high-dose group (20 mg/kg bolus + 5 mg/kg continuous infusion of tranexamic acid). The primary endpoint was intraoperative blood loss volume and total blood loss volume, and secondary endpoints included intraoperative blood transfusion volumes, vasoactive agent consumption, admission into the intensive care unit, and incidence of postoperative complications within postoperative 30 days. The study was registered at ClinicalTrials.gov ID: NCT04360629. RESULTS The patients in the high-dose group had less intraoperative (median [IQR]: 625.3 mL [343.5-1210.5]) and total blood loss volume (748.9 mL [292.2-1650.2]) than those in the control group (1015.5 mL [679.4-1015.5], p = 0.012; and 1700.7 mL [458.7-2419.8], p = 0.004, respectively). In contrast, the intraoperative (992.5 mL [539.0-1404.0], p = 0.874) and total blood loss volume (1025.0 mL [381.8-1819.9], p = 0.113) was not significantly reduced in the low-dose group when compared with the control group. Correspondingly, the relative risk of blood transfusion (RR [95% CI], 0.405 [0.180-0.909], p = 0.028) was reduced in the high-dose group and required less intraoperative noradrenaline (881.0 ± 438.3 mg) to maintain stable hemodynamics than the control group (1548.0 ± 349.8 mg, p = 0.001). Furthermore, compared with the control group, the two tranexamic acid groups had decreased intensive care unit admission rates (p = 0.016) without increasing the incidence of postoperative seizure, acute kidney injury, and thromboembolism. CONCLUSIONS High-dose tranexamic acid is more effective in reducing blood loss and blood transfusion without increasing the risk of postoperative complications. The high-dose regime tended to have a better risk-benefit profile.

Abstract
BACKGROUND Pneumatic tourniquets are widely used in total knee arthroplasty (TKA). Some surgeons prefer a uniform tourniquet inflation pressure (UTIP) for all patients; others use personalized tourniquet inflation pressures (PTIP) based on systolic blood pressure and limb occlusion pressure. However, no consensus exists regarding the optimal mode of inflation pressure during TKA. This review aimed to appraise if personalized tourniquet inflation pressures are better than uniform tourniquet inflation. METHODS The databases (Web of Science, Embase, PubMed, Cochrane Controlled Trials Register, Cochrane Library, Highwire, CBM, CNKI, VIP, Wanfang) were searched on March 2021 to systematically identify and screen the literature for randomized controlled trials involving PTIP and UTIP during total knee arthroplasty. RESULTS Thirteen randomized controlled trials, involving 1204 TKAs (1201 patients) were included in the systematic review. The meta-analysis identified a trend toward less visual analogue scale (VAS) score at rest with PTIP group at 1 day (P = .002), 2 to 3 days (P = .01), and less VAS score at activity 1 day (P < .0001), 2 to 3 days after the operation (P < .00001), and discharge (P < .0001). No significant difference was found between the groups in terms of VAS score at rest when discharge (P = 1.0). We also found no significant difference in terms of intraoperative blood loss (P = .48), total blood loss (P = .15), lower limb vein thrombosis (P = .42), and thigh bullae (P = .17). However, in the PTIP group, we found a significant higher hospital for special surgery (HSS) score (P = .007), broader knee Range of motion (P = .02), less rate of thigh ecchymosis (P = .00001), and shorter thigh circumference at 1 day (P = .006), 2 to 3 days (P = .0005), and discharge (P = .02). CONCLUSION PTIP provides a similar bloodless surgical field compared with the conventional UTIP. Furthermore, PTIP provides less pain intensity, thigh circumference, rate of thigh ecchymosis, higher hospital for special surgery, and better initial recovery of knee flexion in total knee arthroplasty. Therefore, we recommend using a PTIP method during TKA. More adequately powered and better-designed randomized controlled trials studies with long-term follow-up are required to produce evidence-based guidelines regarding the PTIP method.

Journal of orthopaedic surgery and research. 2021;16(1):198
Abstract
BACKGROUND Cement mantle penetration and the cement-bone interface strength were critical to a successful primary total knee arthroplasty (TKA). It remained unclear whether decreased blood and fat in the cancellous bone achieved with the use of a tourniquet increases tibial cement mantle penetration in different zones on AP and lateral view in TKA according to criteria defined by the Knee Society Scoring System (KSS). The purpose of this study was to determine whether tourniquet use influences tibial cement mantle penetration in different zones on AP and lateral view in TKA according to KSS. METHODS We conducted a meta-analysis to identify studies involving the impact of tourniquet use and no tourniquet use on tibial bone cement penetration in primary TKA in electronic databases, including Web of Science, Embase, PubMed, Cochrane Controlled Trials Register, Cochrane Library, Highwire, CBM, VIP, Wanfang database, up to January 2021. Finally, we identified 1231 patients (1231 knees) assessed in twelve studies. RESULTS Tourniquet use increases the cumulative cement mantle penetration (P < 0.00001), mean cement mantle penetration (P = 0.004), and cement mantle in zone 3(P < 0.0001) on AP view. However, there were no significant differences in cement mantle in zone 1(P = 0.5), zone 2(P =0 .54), zone 4(P = 0.07) on AP view, and zone 1(P = 0.32), zone 2(P = 0.38) on lateral view between two groups. There were also no significant differences in length of surgery(P = 0.7), change in hemoglobin(P = 0.4), transfusion rates(P = 0.47), and complications such as muscular calf vein thrombosis(P = 0.21), superficial infection (P = 0.72), and deep vein thrombosis (P = 0.66) between two groups. CONCLUSION The application of a tourniquet increases the thickness of the tibial bone cement penetration-the increase in the thickness of bone cement penetration mainly located in zone 3 on the anteroposterior (AP) view.

Abstract
BACKGROUND CONTEXT Tranexamic acid (TXA) is widely used in surgery for adolescent idiopathic scoliosis (AIS) and has been proved to be efficacious in reducing intraoperative blood loss (IBL) and the transfusion rate. However, the routine TXA regimen was intraoperative administration alone, in which the concentration of TXA could not cover the whole process of hyperfibrinolysis. And, its ability to control the massive postoperative blood loss (PBL) may be insufficient. Thus, we promoted a multiple-dose regimen of TXA for patients with AIS who underwent surgical correction. PURPOSE The primary aims were (1) to determine whether the multiple-dose regimen of TXA could reduce PBL and the postoperative transfusion rate, and (2) to compare the efficacy of oral administration with intravenous administration. The secondary aims were (3) to evaluate whether this regimen could alleviate inflammatory response, and (4) to assess the occurrence of drug-related side effects. STUDY DESIGN Prospective, double-blinded, randomized controlled trial PATIENT SAMPLE A total of 108 patients with AIS who underwent posterior scoliosis correction and spinal fusion (PSS) were enrolled in this study. OUTCOME MEASURES The primary parameters were PBL and postoperative transfusion rate. Other parameters such as total blood loss (TBL), maximum hemoglobin (Hb) decrease, volume of drainage, inflammation markers [interleukin-6 (IL-6) and C-reactive protein (CRP)], and occurrence of complications were also collected and compared. Multiple regression analysis was used to examine the variables that affected PBL. METHOD Patients were randomized into three groups. All patients received intravenous TXA 50 mg/kg loading dose and 10 mg/kg/h maintenance dose during surgery. Group A received 1 g oral TXA at 4 h, 10 h, and 16 h postoperatively; group B received 0.5 g intravenous TXA at 6 h, 12 h, and 18 h postoperatively; group C received placebo. RESULTS The mean PBL and postoperative transfusion rate in group A (957.8±378.9 mL, 13.89%) and B (980.3±491.8 mL, 11.11%) were significantly lower than those in group C [1495.9±449.6 mL, mean differences = 538.1 mL, 95% confidence interval (CI), 290.1-786.1 mL, p<0.001; 515.6 mL, 95% CI, 267.6-763.6 mL, p<0.001]; (36.11%, p=0.029, p=0.013). Meanwhile, the mean TBL, maximum Hb decrease, and volume of drainage were also significantly lower in group A and B than in group C. IL-6 and CRP in group A and B were significantly lower than in group C from postoperative days 1 to 3. All these differences were not significant between groups A and B. No drug-related complications were observed in any patient. Multiple regression showed that the application of postoperative TXA and number of screws were significant parameters affecting PBL. CONCLUSION A multiple-dose regimen of TXA, either by oral or intravenous application, could be a safe and effective means of controlling PBL and decreasing the postoperative transfusion rate in patients with AIS who underwent scoliosis surgery. In addition, it could inhibit postoperative inflammatory response.

Front Pharmacol. 2020;11:437
Abstract
Background: As a traditional Chinese medicine (TCM) prescription for acute stroke, Liangxue Tongyu formula (LXTYF) was widely used as auxiliary treatment measure in some clinical practice. This study aimed to evaluate the clinical efficacy and safety of LXTYF combined western conventional medicine (WCM) with WCM only for acute intracerebral hemorrhage (ICH). Methods: We systematically searched PubMed, Embase, Cochrane Library, CMB (Chinese biomedicine database), CNKI (China National Knowledge Infrastructure), WanFang, and VIP until August 2019 to confirm relevant randomized controlled trials (RCTs) compared the combination of LXTYF and WCM with WCM alone for the treatment of acute ICH. Two investigators independently assessed the risk of bias, and extracted and analyzed the data from the identified studies using RevMan 5.3.0 software following Cochrane's standard and PRISMA guidelines. The herbal compositions of LXTYF were also assessed. Results: 15 RCTs were identified, totally recruiting 1648 patients with acute intracerebral hemorrhage. Compared with the WCM alone, the combination therapy of LXTYF with WCM could improve the clinical effective rate (RR, 1.21; 95% CI, 1.15-1.25, P < 0.05) and ADL score (MD, 18.09; 95% CI, 12.11-24.07; P < 0.05), and reduce syndrome scores of the TCM (MD, -4.11; 95% CI, -4.69 to -3.53; P < 0.05) and the Glasgow outcome score(GOS) (MD=0.43, 95%CI: 0.06 to 0.79, P=0.02) Moreover, there was no sufficient evidence to indicate the adverse effects would increase compared with WCM alone. Conclusion: Based on current evidence, we concluded that the combined therapy had some benefits in treating acute intracerebral hemorrhage. However, considering the potential biases and limitations of our study, additional large, high-quality RCTs are required in the future to confirm or refute the effects of LFTYF combined with WCM in acute stroke.

Abstract
OBJECTIVE Efficacy of minimally invasive craniopuncture with the YL-1 puncture needle (hard-channel) and soft drainage tube (soft-channel) in treating hypertensive intracerebral hemorrhage (HICH). MATERIALS AND METHODS Totally 150 HICH patients were randomly assigned into three groups, conservative group (n=50), hard-channel group (n=50) and soft-channel group (n=50). Computed tomography, National Institutes of Health Stroke Scale (NIHSS) and levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), superoxide dismutase (SOD) and malondialdehyde (MDA) in serum and in drainage fluid were examined on day2, 4, 6 post operation. RESULTS Compared with conservative group, serum levels of IL-6, TNF-alpha and MDA were decreased and SOD was increased (p<0.05); volumes of hematoma and peri-hematomal edema as well as NIHSS were reduced (p<0.05) in minimally invasive groups on day7, 14, 28 post operation. Compared with the hard-channel group, serum levels of IL-6, TNF-alpha, MDA and SOD appeared the same trend as above in the soft-channel group. In the soft-channel group, MDA was reduced and SOD was increased in brain drainage fluid on day2, 4, 6 (p<0.05); volumes of hematoma and peri-hematomal edema on day14, 28 appeared reduction compared with the hard-channel group (p<0.05). There was no significant difference of volumes of hematoma and peri-hematomal edema on day7 between minimally invasive groups. NIHSS of the soft-channel group appeared a significant reduction on day7, 14, 28 post operation (p<0.05). CONCLUSION Soft-channel minimally invasive craniopuncture is an ideal technique for treating HICH, with advantages of alleviating cerebral edema, reducing oxidative stress and inhibiting inflammatory response.

Abstract
OBJECTIVE Restless legs syndrome (RLS) is a common neurological disorder of unclear pathophysiology that appears to involve an iron deficiency in the brain. Some studies, but not others, suggest that intravenous injection of iron can reduce RLS severity. METHOD The databases Web of Science, PubMed, Embase, Chinese National Knowledge Infrastructure, Wanfang, and SinoMed were searched for randomized controlled trials, cohort studies and case-control studies of intravenous iron therapy to treat RLS. Eligible studies were meta-analyzed using Stata 12.0. RESULTS This analysis indicated that IV iron was more efficacious than placebo in treating RLS (OR: 4.71,95%CI 4.21-5.21,p < 0.0001). According to sub-group analysis, either IV ferric carboxymaltose (FCM) or iron sucrose was more efficacious than placebo in treating RLS. Adverse events did not differ significantly between patients receiving intravenous iron or placebo (OR 1.68, 95%CI 0.92-3.07, p = 0.093). The present study also indicated after accepting IV iron treatment the IRLS score in RLS patients decreased (OR = 6.75,95%CI 4.02-9.49, p < 0.0001). The subgroup analysis showed that IV iron dextran, iron sucrose, and FCM could alleviate the IRLS score. CONCLUSION The available evidence suggests that intravenous iron is effective and tolerable for patients with RLS regardless of peripheral iron status.

Pakistan journal of medical sciences. 2019;35(2):377-382
Abstract
Objective: To analyze the effects of neuroendoscopic minimally invasive surgery and small bone window craniotomy hematoma clearance through comparing clinical indicators of the two operation modes and to provide a reference for selection of proper minimally invasive surgery. Methods: One hundred and twenty-six patients with hypertensive cerebral hemorrhage who received diagnosis and treatment in our hospital between December 2015 and December 2017 were selected and grouped into an observation group (n=63) and a control group (n=63) using random number table. Patients in the observation group were treated by neuroendoscopic surgery, while patients in the control group were treated by small bone window craniotomy. The surgical condition, clinical effect and prognosis of the two groups were analyzed and compared. Results: Patients in the observation group completed surgery in a shorter time and bled less during operation compared to the control group, and the hematoma clearance rate of the observation group was obviously higher than that of the control group; the differences had statistical significance (P<0.05). The nerve deficiency scale (NDS) scores of the two groups at the postoperative 3(rd) month were lower than those before surgery (P<0.05), and the activity of daily life (ADL) score at the postoperative 3(rd) month was higher than that before surgery (P<0.05). The observation group had lower NDS score and higher ADL score compared to the control group, and the differences had statistical significance (P<0.05). The incidence of complications of the observation group was lower than that of the control group after surgery, and the rate of favourable prognosis of the observation group was higher than that of the control group at the postoperative 3(rd) month (P<0.05). Conclusion: Neuroendoscopic surgery is more effective and safe, causes less bleeding and has better prognosis and nerve function recovery compared to small bone window craniotomy in the treatment of hypertensive cerebral hemorrhage.

Abstract
Objective To evaluate the hemostatic effect of hemocoagulase agkistrodon on surgical wound in breast cancer surgery. Methods Totally 60 patients undergoing breast cancer surgery were enrolled in this prospective,randomized,double-blinded,and controlled study. All the patients met the inclusion and exclusion criteria and signed the informed consent. Hemocoagulase agkistrodon (2 U) was injected 20 minutes before surgery and 4 and 24 hours after surgery in the intervention group (n=30),whereas normal saline was used instead in the control group (n=30). The volume of intraoperative bleeding,wound drainage volume 1-3 days after surgery,and total drainage volume were recorded. Meanwhile,the change of blood coagulation function,treatment safety,and clinical outcomes were observed. Results The intra-operative hemorrhage volume of the intervention group [(95.0+/-48.3)g] was significantly lower than that of the control group [(144.8+/-105.4)g] (t=-2.07,P=0.044). The volume of total drainage of the intervention group [(166.7+/-71.2)g] was significantly lower than that of the control group [(251.4+/-166.3)g] (t=-2.29,P=0.029). The hemoagglutination indicators were similar in the two groups and no complication such as thrombosis occurred. The length of hospital stay of the intervention group [(15.00+/-3.53)d] was similar to that of the control group [(15.92+/-2.32)d] (t=-1.057,P=0.297). No research drug-related adverse event was occurred in our study. Conclusion Hemocoagulase agkistrodon has good hemostatic effect for patients undergoing breast cancer surgery without increasing the risk of thrombosis.
