BACKGROUND Platelet-rich plasma (PRP) and corticosteroids are used to treat rotator cuff diseases. However, few reviews have compared the effects of these two treatments. In this study, we compared the effects of PRP and corticosteroid injection on the prognosis of rotator cuff diseases. METHODS According to the Cochrane Manual of Systematic Review of Interventions, the PubMed, Embase, and Cochrane databases were searched comprehensively. Two independent authors screened suitable studies and performed data extraction and risk of bias assessment. Only randomized controlled trials (RCTs) comparing the effects of PRP and corticosteroid in the treatment of rotator cuff injuries were included, as measured by clinical function and pain during different follow-up periods. RESULTS Nine studies with 469 patients were included in this review. In short-term treatment, corticosteroids were superior to PRP in the improvement of constant, SST, and ASES scores (MD -5.08, 95%CI -10.26, 0.06; P = .05 and MD -0.97, 95%CI -1.68, -0.07; P = .03 and MD -6.67, 95%CI -12.85, -0.49; P = .03, respectively). No statistically difference was observed between the two groups at mid-term (P> .05), and the recovery of the SST and ASES scores in PRP treatment was significantly better than that in corticosteroid treatment in the long-term (MD 1.21, 95%CI 0.68, 1.74; P < .00001 and MD 6.96, 95%CI 3.90, 9.61; P < .00001, respectively). In pain reduction based on VAS score, corticosteroids led to better pain reduction (MD 0.84, 95%CI 0.03, 1.64; P = .04), but no significant difference was observed in pain reduction between the two groups in the any term (P> .05). However, these differences did not reach the minimum clinically important difference. CONCLUSION Current analysis showed that corticosteroids have better efficacy in short-term, whereas PRP is more beneficial for long-term recovery. However, no difference was observed in the mid-term efficacy between the two groups. RCTs with longer follow-up periods and larger sample sizes are also needed to determine the optimal treatment.

To systematically review of randomized controlled trials(RCTs) to compared the effects of leukocyte-rich and leukocyte-poor platelet-rich plasma in arthroscopic rotator cuff repair. Two independent reviewers comprehensively searched PubMed, Embase, and Cochrane library databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Comparison of leukocyte-rich platelet-rich plasma or leukocyte-poor platelet-rich plasma in rotator cuff repair in a level I RCTs. Methodological quality assessment was carried out using Cochrane Review Manager 5.3 software. P<0.05 was considered statistically significant. Nine RCTs with 540 patients were included in this review. Meta-analysis showed that leukocyte-poor platelet-rich plasma in significantly reduced retear rate in rotator cuff repair [RR=0.56 95%CI (0.42,0.75); P＜0.05), and in clinical results, the constant score [MD=3.67, 95%CI (1.62,5.73); P=0.0005], UCLA score [MD=1.60, 95%CI (0.79,2.42); P=0.0001], ASES score [MD=2.16, 95%CI(0.12,4.20);P=0.04] were significantly improved. There was a significant result in favor of PRP for the Constant score [MD=-1.24, 95%CI(-1.50,-0.99); P＜0.00001], while SST scores were not significantly different among all groups [MD=0.21, 95%CI(-0.21,0.64); P=0.32]. In conclusion, leukocyte-poor platelet-rich plasma can improved the clinical function and reduced retear rate in arthroscopic rotator cuff repair. In contrast, the efficacy of leukocyte-rich platelet-rich plasma was not significantly improved with the exception of VAS score.

BACKGROUND As a relatively minimally invasive technique, endoscopic submucosal dissection (ESD) is widely used for the treatment of gastrointestinal lesions. However, it is associated with complications, such as postoperative bleeding, stricture, and perforation. A covering method using polyglycolic acid (PGA) sheets for ESD-induced ulcers has been reported to be effective in reducing the risk of post-ESD bleeding and esophageal stricture. Herein, we conducted a systematic review and meta-analysis to evaluate the role of PGA sheets in the prevention of gastrointestinal bleeding and esophageal stricture after ESD. METHODS We searched PubMed, Web of Science, and the Cochrane Library databases on October 15, 2019. All eligible articles were selected based on the predefined inclusion and exclusion criteria. The main outcomes were the rates of post-ESD gastrointestinal bleeding and esophageal stricture. Cochrane's Q statistic and I2 test were used to identify heterogeneity between the studies. When there was no obvious heterogeneity (I2 < 50%, P > .1), a fixed-effect model was used. When there was obvious heterogeneity (I2 > 50%, P < .1), a random effect model was used. Funnel plots and the Egger regression test were used to assess publication bias. RESULTS Fifteen articles were included in the meta-analysis, of which 7 were exclusively about the use of PGA sheets to prevent postoperative gastrointestinal bleeding, and the remaining reported the use of PGA sheets to prevent postoperative esophageal stenosis. Our analysis showed that preventive therapy with PGA sheets decreased the rates of post-ESD gastrointestinal bleeding (risk ratio [RR] = 0.35, 95% confidential interval [CI]: 0.19-0.64, P < .001) and esophageal stricture (RR = 0.46, 95% CI: 0.27-0.79, P = .005), and the gastrointestinal bleeding and esophageal stricture rates after preventive treatment with PGA sheets were 5.7% (95% CI: 3.6%-8.8%) and 20.6% (95% CI: 14.5%-28.4%), respectively. CONCLUSION The utilization of PGA sheets after ESD has an excellent outcome in reducing the risk of postoperative gastrointestinal bleeding and esophageal stricture.

BACKGROUND Although intravenous tranexamic acid administration (ivTXA) has prevailed in clinical antifibrinolytic treatment, whether it increases thromboembolic risks has remained controversial. As a potent alternative to ivTXA, topical use of TXA (tTXA) has been successfully applied to attenuate blood loss in various surgical fields while minimizing systemic exposure to TXA. This meta-analysis was conducted to gather scientific evidence for tTXA efficacy on reducing postoperative drainage, blood loss, and the length of hospital stay in spine surgeries. OBJECTIVES To examine whether topical use of TXA (tTXA) reduces postoperative drainage output and duration, hidden blood loss, hemoglobin level drop, hospital stay, and adverse event rate, we reviewed both randomized and non-randomized controlled trials that assessed the aforementioned efficacies of tTXA compared with placebo in patients undergoing cervical, thoracic, or lumbar spinal surgeries. METHODS An exhaustive literature search was conducted in MEDLINE and EMBASE databases from January 2000 through March 2020. Measurable outcomes were pooled using Review Manager (RevMan) version 5.0 in a meta-analysis. RESULTS Significantly reduced postoperative drainage output (weighted mean difference [WMD]= - 160.62 ml, 95% confidence interval (95% CI) [- 203.41, - 117.83]; p < .00001) and duration (WMD= - 0.75 days, 95% CI [- 1.09, - 0.40]; p < .0001), perioperative hidden blood loss (WMD= - 91.18ml, 95% CI [- 121.42, - 60.94]; p < .00001), and length of hospital stay (WMD= - 1.32 days, 95% CI [- 1.90, - 0.74]; p < .00001) were observed in tTXA group. Pooled effect for Hb level drop with tTXA vs placebo crossed the equivalent line by a mere 0.05 g/dL, with the predominant distribution of 95% confidence interval (CI) favoring tTXA use. CONCLUSIONS With the most comprehensive literature inclusion up to the present, this meta-analysis suggests that tTXA use in spinal surgeries significantly reduces postoperative drainage, hidden blood loss, and hospital stay duration. The pooled effect also suggests that tTXA appears more effective than placebo in preserving postoperative Hb level, which needs further validation by future studies.

BACKGROUND Conventional endoscopic treatments can't control bleeding in as many as 20% of patients with non-variceal gastrointestinal (GI) bleeding. Recent studies have shown that over-the-scope-clip (OTSC) system allowed for effective hemostasis for refractory GI bleeding lesions. So we aimed to conduct a systematic review to evaluate the effectiveness and safety of the OTSC system for management of acute non-variceal upper GI bleeding. METHOD A comprehensive literature search was conducted on PubMed, EMBASE, and Cochrane Library covering the period from January 2007 to May 2019. The literature was selected independently by two reviewers according to the inclusion and exclusion criteria. The statistical analysis was carried out using Comprehensive Meta-Analysis software version 3.0. RESULTS A total of 16 studies including 769 patients with 778 GI bleeding lesions were identified. Pooled technical success was achieved in 761 lesions [95.7%; 95% confidence interval (CI), 93.5-97.2%], and the pooled clinical success was achieved in 666 lesions (84.2, 95% CI, 77.4-89.2%). The incidence of re-bleeding was reported in 81 patients and the post-procedure mortality was 10.9% (n = 84). Only 2 (0.3%) patients occurred complications after OTSC system procedure. CONCLUSIONS Our study demonstrated that the OTSC system was a technically feasible modality and highly efficacious in achieving hemostasis in acute non-variceal upper gastrointestinal bleeding.

Hemorrhagic chronic radiation proctopathy (CRP) is a common complication after pelvic radiotherapy in patients with prostate or gynecological cancers. This systematic review was conducted to evaluate the efficacy and safety of argon plasma coagulation (APC) in treating hemorrhagic CRP. The databases of PubMed, Embase, and Cochrane Library were searched for related studies from inception to July 2017. Finally, 33 studies were identified with a total of 821 hemorrhagic CRP patients. After APC treatment, hemoglobin levels increased from 7.7-13.4 g/L to 11-14 g/L (including 15 studies). All (n = 33) studies reported an effective rate in rectal bleeding, among which five studies had a rate of 100%. Short-term complications were reported in 31 studies, while long-term complications in 33 studies and no complication in 11 studies. As for the severe complications, perforation was reported by 2 out of 33 studies, and the incidences were 3.3% (1/30) and 3.7% (1/27), respectively. As for APC setting, argon gas flow rate (median 1.5 L/min) and electric power (median 50 W) had no significant influence on complications and hemostasis. In conclusion, current literature indicated that APC therapy was an effective and safe strategy for hemorrhagic CRP, and large-scale prospective studies are needed to warrant our study.

BACKGROUND Volume replacement therapy with colloid is still worth studying in major pediatric surgery with potential risk of bleeding. This study assessed the effects of 6% hydroxyethyl starch (HES) 130/0.4 and 5% Human Albumin (HA) on coagulation tested by thromboelastography (TEG) during elective intracranial tumor surgery in pediatric patients. METHODS In this randomized controlled trial, 60 patients undergoing intracranial tumor resection under general anesthesia were assigned to HES and HA groups (n = 30), and administered preloads of 20 mL . kg-1 HES 130/0.4 and 5% HA, respectively, prior to dura opening. Primary outcomes were perioperative thromboelastography findings, and hemodynamic and hematological parameters. Blood transfusion, perioperative fluid balance, intracranial pressure, mortality, intensive care unit stay, and hospital stay were also assessed. RESULTS TEG parameters did not differ after preloading compared to baseline values in either group, except for a decrease in maximum amplitude immediately after infusion (HES group, 57.6 +/- 6.0 mm vs. 50.9 +/- 9.2 mm; HA group, 60.1 +/- 7.9 mm vs. 56.6 +/- 7.1 mm; p < 0.01), which was restored to preoperative levels 1 h after fluid infusion. Total perioperative fluid balance, blood loss or transfusion, intracranial pressure, and hematological and hemodynamic variables were similar between both groups (p > 0.05). Mortality, length of hospital stay, and clinical complications were similar between both groups. CONCLUSION These findings suggest that HES and HA might have no significant differences regarding coagulation as assessed by TEG during pediatric intracranial tumor surgery with 20 ml/kg volume pre-loading, which can maintain stable hemodynamics and may represent a new avenue for volume therapy during brain tumor resection in pediatrics.

OBJECTIVE To investigate the effect of different intravenous iron treatment regimens on anemia and oxidative stress in maintenance hemodialysis (MHD) patients. METHODS A total of 58 MHD patients were randomly divided into a multi-frequency low-dose intravenous iron group (iron sucrose 25 mg, twice a week for 8 weeks, n=19), a less-frequency regular-dose intravenous iron group (iron sucrose 100 mg, once every two weeks for 8 weeks, n=19), and a non-iron group (n=20). Another 20 healthy people served as a control group (n=20). The changes of hemoglobin (Hb), hematocrit (HCT), serum ferritin (SF) and transferrin saturation (TSAT), as well as the oxidative stress parameters of malon-dialdehyde (MDA), superoxide dismutase (SOD) and myeloperoxidase (MPO) were detected before and after the treatment. RESULTS After 8 weeks, compared with the non-iron group, the levels of Hb, HCT, SF and TSAT in the two iron groups were significantly elevated (P<0.01), but there was no difference between the two iron groups (P>0.05). After the single dialysis, the two iron groups had higher level of serum MDA, MPO and lower level of serum SOD than that of the non-iron supplementation group (P<0.01). The multi-frequency low-dose intravenous iron group had lower level of serum MDA [(5.37 +/- 0.73) nmol/mL vs (6.37+/-1.67) nmol/mL], MPO [(81.41+/-7.60) U/L vs (96.75+/-16.97) U/L] and higher level of serum SOD [(84.77 +/- 14.02) U/mL vs (68.23 +/- 4.90) U/mL] than that of the less-frequency regular-dose intravenous iron group. After 8 weeks, there was no significant difference between the two iron groups (P>0.05). CONCLUSION Multi-frequency low-dose intravenous iron can effectively improve anemia in MHD patients, whose acute oxidative stress is lower than that of less-frequency regular-dose intravenous iron, and is a relatively safe and effective intravenous iron treatment regimen.
