Abstract
INTRODUCTION The efficacy of tourniquet use during primary total knee arthroplasty (TKA) is thought to reduce intraoperative blood loss, improve surgical exposure, and optimize cement fixation. Tranexamic acid (TXA) use can decrease postsurgical blood loss and transfusion requirements. This review aimed to appraise the effects of tourniquet use in TKA for patients with tranexamic acid use. METHODS A meta-analysis was conducted to identify relevant randomized controlled trials involving TXA plus a tourniquet (TXA-T group) and use of TXA plus no tourniquet (TXA-NT group) in TKA. Web of Science, PubMed, Embase, Cochrane Controlled Trials Register, Cochrane Library, Highwire, CNKI, and Wanfang database were searched from 2010 through October 2021. RESULTS We identified 1720 TKAs (1690 patients) assessed in 14 randomized controlled trials. Compared with the TXA-NT group, the TXA-T group resulted in less intra-operative blood loss (P < 0.00001) and decreased duration of surgery (P < 0.00001), however more hidden blood loss (P = 0.0004) and less knee range of motion (P < 0.00001). No significant differences were found between two groups in terms of decrease in hemoglobin (P = 0.84), total blood loss (P = 0.79), transfusion rate (P = 0.18), drainage volume (P = 0.06), Visual Analogue Scale (VAS) at either the day of surgery (P = 0.2), 1 day (P = 0.25), 2 day (P = 0.39), 3 day (P = 0.21), 5 day (P = 0.21), 7 day (P = 0.06) or 1 month after surgery (P = 0.16), Hospital for Special Surgery (HSS) score at either 7 day (P = 0.10), 1 month (P = 0.08), 3 month (P = 0.22) or 6 month after the surgery (P = 0.92), Knee circumference (P = 0.28), length of hospital (P = 0.12), and complications such as intramuscular venous thrombosis (P = 0.81), deep venous thrombosis (P = 0.10), superficial infection (P = 0.45), deep wound infection (P = 0.64), and delayed wound healing (P = 0.65). CONCLUSION No big differences could be found by using or not tourniquet when use the TXA, though some benefits are related to operation time and less intra-operative blood loss by using tourniquet and TXA, Using the tourniquet was related to more hidden blood loss and less knee range of motion. More adequately powered and better-designed randomized controlled trials (RCTs) studies with long-term follow-up are required to validate this study.

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.

Frontiers in surgery. 2022;9:850139
Abstract
OBJECTIVE To explore the effects of two different hemostasis methods, namely, arterial compression devices and vascular closure devices, in the ischemic cerebrovascular intervention to provide a theoretical basis for clinical selection of hemostasis methods. METHODS A total of 302 patients who underwent ischemic cerebrovascular intervention in our hospital from January 2016 to December 2020 were selected as the research subjects and randomly divided into the control group (n = 151) and the observation group (n = 151). The patients in both groups underwent cerebrovascular intervention. The patients in the control group were treated with an artery compressor for hemostasis after the operation, while those in the observation group were treated with vascular closure devices for hemostasis. The hemostatic indexes and vascular parameters at the puncture site before and after the operation were compared between the two groups. The comfort level of the patients was assessed at 6, 12, and 24 h after the operation with the Kolcaba Comfort Scale score, and the postoperative complications were recorded. RESULTS There was no significant difference in the success rate of hemostasis between the two groups (p > 0.05). The hemostatic time and immobilization time of (2.69 ± 0.62) min and (4.82 ± 0.93) h in the observation group were lower than those in the control group with (16.24 ± 3.58) min and (7.94 ± 1.86) h (p < 0.05). The differences in the minimum inner diameter of the puncture site and its nearby vessels and the peak velocity of blood flow between the two groups before and after the operation were not statistically significant within or between groups (p > 0.05). The scores of the Kolcaba comfort scale in the observation group (80.16 ± 8.49) and (93.65 ± 9.26) at 6 and 12 h, respectively, after the operation, were higher than those in the control groups (72.08 ± 7.54) and (85.49 ± 8.63) (p < 0.05). The 24 h postoperative Kolcaba comfort scale score was (97.54 ± 9.86) in the observation group and (96.82 ± 9.64) in the control group, and the difference was not statistically significant (p > 0.05). In the control group, there were 7 cases of dysuria, 12 cases of low back pain, 14 cases of sleep disorder, 20 cases of mental stress, and 5 cases of wound bleeding, and the total incidence of complications was 38.41% (58/151). In the observation group, there were 4 cases of dysuria, 8 cases of low back pain, 10 cases of sleep disorder, 14 cases of mental stress, and 3 cases of wound bleeding, and the total incidence of complications was 25.83% (39/151). The total incidence of complications in the observation group was lower than that in the control group (p < 0.05). CONCLUSION For patients with ischemic cerebrovascular disease undergoing femoral artery puncture intervention, the use of vascular closure devices can stop the bleeding quickly, which can significantly shorten the bleeding time, and the postoperative braking time of patients is short, with high comfort and fewer complications.

Journal of clinical pharmacy and therapeutics. 2022
Abstract
WHAT IS KNOWN AND OBJECTIVE The clinical features of terlipressin-induced ischemic skin necrosis are unknown. The purpose of this study is to explore the clinical features of terlipressin-induced skin necrosis. METHODS We searched Chinese and English databases to collect case reports of terlipressin-induced skin necrosis for retrospective analysis. RESULTS AND DISCUSSION A total of 42 patients (31 males and 11 females) from 35 studies were included, with a median age of 54 years (range 0.17-84). The onset of skin ischemia ranged from a few hours to 21 days. The most common clinical manifestations were bulla (15 cases, 35.7%), cyanosis (12 cases, 28.6%), necrosis (11 cases, 26.2%), and purpura (10 cases, 23.8%). The following were often affected: the legs (26 cases), 61.9%), abdomen (13, 31.0%), scrotum (10 cases, 23.8%), feet (10 cases, 23.8%), upper extremities (8 cases, 19.0%), and hands (7 cases, 16.7%). Skin biopsy showed fibrin thrombus (7 cases, 38.9%), nonspecific inflammation (6 cases, 33.3%), and necrosis (10 cases, 55.6%). After discontinuation of terlipressin, skin symptoms improved in most patients. WHAT IS NEW AND CONCLUSION Ischemic skin necrosis is a rare and serious adverse effect of terlipressin. Patients receiving terlipressin therapy should be monitored closely for terlipressin-related ischemic complications. Terlipressin should be discontinued immediately if ischemic complications occur.

Clinical oral implants research. 2022
Abstract
OBJECTIVES To evaluate patient-reported outcomes and radiographic results of simultaneous implant placement in severely atrophic maxilla using flapless endoscope-assisted osteotome sinus floor elevation with platelet-rich fibrin (PRF), also defined as PESS, and to compare the results with those of lateral sinus floor elevation (LSFE). METHODS Patients with a residual bone height (RBH) of 2-6 mm were included in a randomised controlled trial. PESS was performed with PRF as the sole grafting material. LSFE was performed using deproteinised bovine bone matrix. Patient-reported outcomes were recorded on a visual analogue scale (VAS-pain) and visual rating scale (VRS-swelling and VRS-willingness). Peri-implant bone height (PBH), bone mineral density (BMD), and sinus grafting remodelling index were measured using CBCT immediately postoperatively and 3(rd) , 6(th) and 18(th) months post-surgery. RESULTS The study population consisted of 20 patients in each group. The RBH of two groups averaged 3.35±0.79 mm and 2.92±0.63 mm with no significant difference (p > 0.05). VAS-pain was 18.0 (IR 15.0-22.5) and 35.0 (IR 32.5-37.0) in the PESS and LSFE groups, respectively (p < 0.01). VAS-pain decreased with time in both groups. VRS-swelling was lower in the PESS group than LSFE group. VRS-willingness was higher in the PESS group than LSFE group (p < 0.01). At 18 months post-surgery, the marginal bone loss was 0.60±0.25 mm and 0.69±0.35 mm in the two groups with no significant difference (p = 0.52). CONCLUSIONS Within the limitations of this study, PESS was associated with lower postoperative morbidity and was more tolerable than LSFE. PESS could be a reliable procedure for sinus floor elevation in patients with insufficient RBH.

Frontiers in pharmacology. 2022;13:906075
Abstract
Purpose: Carpal tunnel syndrome (CTS) is a common form of median nerve compression in the wrist caused by focal peripheral neuropathy. Platelet-rich plasma (PRP) therapy could improve the healing ability by exposing the injured tissues to high concentrations of autologous growth factors. Our study aims to compare all injective treatments for CTS and assess the efficacy and priority of PRP therapy. Methods: We searched Medline, Embase, Web of Science, Cochrane databases, and Clinicaltrial.gov until 17 October 2022. We only included data from randomized controlled trials (RCTs) that evaluated PRP injection therapy or drug injection therapy. The included RCTs measured at least one of the following three outcomes with validated instruments: in the visual analog scale (VAS), symptom severity scale (SSS), and functional status scale (FSS). Results: Overall, 19 studies with 1,066 patients were included in this study. We used the SUCRA rankings to determine the merits of various therapies. In all, 5% dextrose injections were the best treatment strategy for the VAS (MD -1.22, 95% CI -2.66 to 0.23; SUCRA = 79.2%), followed by triamcinolone (high-dose) injections (MD -0.69, 95% CI -2.11 to 0.73; SUCRA = 62.7%) and PRP injections (MD -0.39, 95% CI -1.67 to 0.89; SUCRA = 60.0%). In the SSS, the most effective intervention was hydroxyprogesterone injections (MD -0.62, 95% CI -1.09 to -0.16; SUCRA = 91.0%). The SUCRA ranking of PRP was second only to steroids and estrogen (MD -0.39, 95% CI -0.60 to -0.18; SUCRA = 60.8%). In the FSS, the best regimen strategy was hydroxyprogesterone injections (MD 0.12, 95% CI -0.30 to 0.54; SUCRA = 99.5%), followed by triamcinolone (low-dose) injections (MD -0.02, 95% CI -0.54 to 0.49; SUCRA = 87.4%) and PRP injections (MD -0.26, 95% CI -0.43 to -0.09; SUCRA = 77.1%). Conclusion: PRP is an alternative choice for CTS treatment. PRP injection is second only to steroids and estrogen in the treatment efficacy of CTS, with a wide indication and safe outcome.

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.

Clinical laboratory. 2021;67(1)
Abstract
BACKGROUND To explore the effects of isovolumic hemodilution and platelet-rich plasma separation on platelet activation state and function, complications, and inflammation in patients undergoing cardiac surgery. METHODS A total of 80 patients who needed cardiac surgery under extracorporeal circulation from February 2018 to December 2019 in our hospital were selected as research subjects and divided into observation group (n = 40) and control group (n = 40) according to the random number table method. The patients in the observation group underwent platelet-rich plasma separation, while those in control group received acute isovolumic hemodilution. Then the platelet activation state and functional indexes, hemorheological indexes, and the coagulation functional indexes were compared between the two groups of patients before operation. Next, the changes in the levels of hemoglobin and high-sensitivity C-reactive protein (hs-CRP), an inflammatory factor, during blood protection (before and at 6 hours and 12 hours after intervention) were analyzed. Moreover, the dosage of blood products during operation was compared between the two groups, and postoperative complications and recovery in the two groups were statistically assessed. RESULTS Before operation, the platelet adherence rate and aggregation rate in the observation group were significantly higher than those in control group (p < 0.05), while R and K values in thromboelastograms in the former were notably smaller than those in the latter (p < 0.05). Meanwhile, the whole blood low-shear viscosity, whole blood high-shear viscosity, and plasma viscosity in observation group were remarkably lower than those in control group (p < 0.05). In addition, the observation group exhibited shorter prothrombin time (PT), thrombin time (TT), and activated partial thromboplastin time (APTT) (p < 0.05) and a higher fibrinogen (Fib) level (p < 0.05) than the control group. At 6 hours and 12 hours after intervention and before operation, the hemoglobin level in observation group was markedly higher than that in control group (p < 0.05). In addition, the dosages of red blood cells, fresh frozen plasma, and platelets among blood products during operation in the observation group were evidently lower than those in the control group (p < 0.05), and the number of cases of hemorrhage, pulmonary infection, coagulation dysfunction, and paraplegia after operation in the former was distinctly smaller than that in the latter (p < 0.05). Furthermore, the observation group had an obviously smaller postoperative 24 hours drainage volume (p < 0.05) as well as shorter postoperative mechanical ventilation time and ICU treatment time than control group (p < 0.05). CONCLUSIONS For patients undergoing cardiac surgery under extracorporeal circulation, platelet-rich plasma separation and reinfusion technology can effectively ensure platelet activation state and function, reduce blood viscosity, ensure stable coagulation function, elevate hemoglobin level and decrease inflammatory reaction, and perioperative allogeneic blood infusion, with fewer adverse reactions in treatment, thus efficaciously facilitating the post-operative recovery of patients.

Medicine. 2020;99(9):e19357
Abstract
BACKGROUND Vonoprazan is a potassium-competitive acid blocker (P-CAB) that is frequently used in Japan for Helicobacter pylori (H. pylori) eradication, treatment of gastroesophageal reflux disease, and treatment of post endoscopic submucosal dissection (ESD) complications. We sought to determine if vonoprazan was superior to proton pump inhibitors (PPIs) for treating ESD-induced ulcers (as assessed by ulcer healing and shrinkage ratios) and preventing delayed bleeding over various treatment durations (2, 4, and 8 weeks). METHODS We collected randomized controlled trials (RCTs) and observational studies that discussed the effectiveness of vonoprazan and PPIs on ESD-induced ulcers and bleeding from PubMed, Cochrane Library, ClinicalTrials.gov, and Google Scholar. Studies were selected according to pre-established eligibility criteria and data were extracted separately by 2 researchers with double-check. We used the Cochrane risk of bias tool to assess RCTs and the Newcastle-Ottawa Quality Assessment Scale to assess observational studies. Meta-analyses, based on the random-effects model, were conducted to compare differences in ulcer shrinkage ratios (%) and odds ratios (ORs) for ulcer healing and delayed bleeding. Publication bias was evaluated using funnel plots and Egger regression test. Heterogeneity was assessed using I statistics. A sensitivity analysis was conducted to check the robustness of results. The evidential quality of the findings was assessed using the GRADE profiler. RESULTS Thirteen studies were included in this meta-analysis. The OR effect sizes of vonoprazan relative to PPIs for ulcer healing were 1.33 (P = .13) with a 95% CI (0.33-3.21) at 4 weeks and 1.48 (P = .09) with a 95% CI (0.81-5.20) at 8 weeks. The overall effect size for the shrinkage ratio was 12.24% (P = .16) with a 95% CI (-4.96-29.44) at 2 weeks. The effect size of its subgroup of H. pylori-positive patients was 19.51% (P < .001) with a 95% CI (11.91-27.12). The overall OR for the occurrence of delayed bleeding was 0.66 (P = .26) with a 95% CI (0.32-1.35). After excluding combination drug studies, the overall ORs between vonoprazan and PPIs on ulcer healing and delayed bleeding were 1.44 and 0.76, respectively. CONCLUSION During the first 2 weeks of treatment, vonoprazan was more effective than PPIs for treating H. pylori-positive patients with ESD-induced gastric ulcers.

Zhang Y, Bai Y, Chen M, Zhou Y, Yu X, Zhou H, Chen G
BMC anesthesiology. 2019;19(1):104
Abstract
BACKGROUND The safety and efficiency of intravenous administration of tranexamic acid (TXA) in coronary artery bypass grafting (CABG) remains unconfirmed. Therefore, we conducted a meta-analysis on this topic. METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), PUBMED and EMBASE for randomized controlled trials on the topic. The results of this work are synthetized and reported in accordance with the PRISMA statement. RESULTS Twenty-eight studies met our inclusion criteria. TXA reduced the incidence of postoperative reoperation of bleeding (relative risk [RR], 0.46; 95% confidence interval [CI]; 0.31-0.68), the frequency of any allogeneic transfusion (RR, 0.64; 95% CI, 0.52-0.78) and the postoperative chest tube drainage in the first 24 h by 206 ml (95% CI - 248.23 to - 164.15). TXA did not significantly affect the incidence of postoperative cerebrovascular accident (RR, 0.93; 95%CI, 0.62-1.39), mortality (RR, 0.82; 95%CI, 0.53-1.28), myocardial infarction (RR, 0.90; 95%CI, 0.78-1.05), acute renal insufficiency (RR, 1.01; 95%CI, 0.77-1.32). However, it may increase the incidence of postoperative seizures (RR, 6.67; 95%CI, 1.77-25.20). Moreover, the subgroup analyses in on-pump and off-pump CABG, the sensitivity analyses in trials randomized more than 99 participants and sensitivity analyses that excluded the study with the largest number of participants further strengthened the above results. CONCLUSIONS TXA is effective to reduce reoperation for bleeding, blood loss and the need for allogeneic blood products in patients undergoing CABG without increasing prothrombotic complication. However, it may increase the risk of postoperative seizures.
