Abstract
PURPOSE The purpose of this study was to explore whether PRP injection can be a viable alternative to CS injection for conservative treatment of rotator cuff disease. METHODS The study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, EMBASE, The Cochrane Library, and Web of Science were searched for English-written randomized controlled trials (RCTs) which compared PRP and CS injections for patients with rotator cuff disease from January 1, 1990, to March 20, 2022. Two evaluators independently screened the literature, extracted data, and assessed the level of evidence and methodological quality of the enrolled studies. The meta-analysis was conducted using RevMan 5.3.3 software. RESULTS Thirteen non-surgical RCTs with 725 patients were included. Compared with CS, PRP provided statistically worse short-term (<2 months) changes (Δ) of the American Shoulder and Elbow Surgeons (ASES) assessment, Δ the Simple Shoulder Test (SST), Δ the Disability of Arm, Shoulder and Hand (DASH) questionnaires but better medium-term (2 to 6 months) Δ DASH, long-term (≥ 6 months) Δ Constant-Murley Score (CMS), Δ ASES and Δ SST. No statistical differences regarding pain reduction were found between the two groups. PRP injections led to worse short-term Δ forward flexion, Δ internal rotation but better medium-term Δ forward flexion and Δ external rotation. PRP had significantly lower rates of postinjection failure (requests for a subsequent injection or surgical intervention prior to 12 months) than CS. No outcome reached the minimal clinically important difference (MCID). After sensitivity analyses by excluding studies with substantial clinical and/or methodological heterogeneity, PRP showed better medium-term Δ ASES, Δ VAS, and long-term Δ VAS which reached the MCID. CONCLUSIONS Without the drawbacks of CS injection, PRP injection is not worse than CS injection in pain relief and function recovery at any time point of the follow-up. PRP injection may reduce rates of subsequent injection or surgery, and might provide better improvement in pain and function in the medium- to long-term. PRP injection can be a viable alternative to CS injection for conservative treatment of rotator cuff disease. LEVEL OF EVIDENCE Systematic review of Level I and II studies.

Abstract
BACKGROUND A reliable scoring tool to detect the risk of intracerebral hemorrhage (ICH) after intravenous thrombolysis for ischemic stroke is warranted. The present study was designed to develop and validate a new nomogram for individualized prediction of the probability of hemorrhagic transformation (HT) in patients treated with intravenous (IV) recombinant tissue plasminogen activator (rt-PA). METHODS We enrolled patients who suffered from acute ischemic stroke (AIS) with IV rt-PA treatment in our emergency green channel between August 2016 and July 2018. The main outcome was defined as any type of intracerebral hemorrhage according to the European Cooperative Acute Stroke Study II (ECASS II). All patients were randomly divided into two cohorts: the primary cohort and the validation cohort. On the basis of multivariate logistic model, the predictive nomogram was generated. The performance of the nomogram was evaluated by Harrell's concordance index (C-index) and calibration plot. RESULTS A total of 194 patients with complete data were enrolled, of whom 131 comprised the primary cohort and 63 comprised the validation cohort, with HT rate 12.2, 9.5% respectively. The score of chronic disease scale (CDS), the global burden of cerebral small vascular disease (CSVD), National Institutes of Health Stroke Scale (NIHSS) score ≥ 13, and onset-to-treatment time (OTT) ≥ 180 were detected important determinants of ICH and included to construct the nomogram. The nomogram derived from the primary cohort for HT had C- Statistics of 0.9562 and the calibration plot revealed generally fit in predicting the risk of HT. Furthermore, we made a comparison between our new nomogram and several other risk-assessed scales for HT with receiver operating characteristic (ROC) curve analysis, and the results showed the nomogram model gave an area under curve of 0.9562 (95%CI, 0.9221-0.9904, P < 0.01) greater than HAT (Hemorrhage After Thrombolysis), SEDAN (blood Sugar, Early infarct and hyper Dense cerebral artery sign on non-contrast computed tomography, Age, and NIHSS) and SPAN-100 (Stroke Prognostication using Age and NIHSS) scores. CONCLUSIONS This proposed nomogram based on the score of CDS, the global burden of CSVD, NIHSS score ≥ 13, and OTT ≥ 180 gives rise to a more accurate and more comprehensive prediction for HT in patients with ischemic stroke receiving IV rt-PA treatment.

Abstract
Objective: The mobilization and collection of sufficient autologous peripheral blood stem cells (APBSCs) are important for the fast and sustained reconstruction of hematopoietic function after autologous transplantation. This study aims to evaluate the mobilization effect and safety of thrombopoietin (TPO) combined with chemotherapy + G-CSF for APBSCs in patients with refractory/relapsed non-Hodgkin's lymphoma. Methods: A total of 78 patients were included in the present study. After receiving mobilization chemotherapy, all patients were randomly divided into two groups: TPO group (n=40), patients were given subcutaneous injection of rhTPO + G-CSF, and control group (n=38), patients were given subcutaneous injection of G-CSF. The primary endpoint was the total number of obtained CD34+ cells. The secondary endpoints were the mononuclear cell count, the proportion of target and minimum mobilization, the engraftment time of neutrophils and platelets after APBSCT, the number of platelet and red blood cell infusions, the incidence of infectious fever and fever duration, and TPO-related side effects in patients. Results: TPO participation significantly increased the total CD34+ cell count. A higher proportion of patients in the TPO group achieved the minimum and target CD34+ cells, when compared to the control group. TPO-related adverse events were not observed in either of these groups. In addition, there were no significant differences in engraftment time, the number of platelet and red blood cell transfusions, the incidence of infectious fever, and fever duration between these two groups. Conclusion: TPO combined with chemotherapy + G-CSF can safely and effectively enhance the mobilization effect for APBSCs in patients with refractory/relapsed non-Hodgkin's lymphoma.

Abstract
BACKGROUND Simultaneous bilateral total knee arthroplasty (TKA) can lead to greater blood loss and higher risk of venous thromboembolism. The effectiveness and safety of tranexamic acid (TXA) in simultaneous bilateral TKAs have not been clearly defined. We presumed that a fixed dose of TXA may be a preferable alternative for ease of administration in patients undergoing simultaneous bilateral TKAs. METHODS We prospectively randomized 120 primary simultaneous bilateral TKAs to a fixed dose of TXA or equivalent volume of normal saline intravenously. The primary outcome measure was total blood loss. The secondary outcome measures were blood transfusion rate, transfusion units, intraoperative blood loss, drainage volumes, hidden blood loss, maximum decline of hemoglobin, and postoperative suprapatellar girth increment. RESULTS There were statistically significant lower total blood loss, blood transfusion rate, drainage volumes, transfusion units, and maximum decline of hemoglobin in the TXA group than in the control group (P < .05), without increasing incidence of asymptomatic and symptomatic venous thromboembolism. However, TXA did not significantly reduce the hidden blood loss (P = .123). No differences were observed in suprapatellar girth increments between both groups on postoperative day 5 and week 6 (P = .251 and .299). CONCLUSION Fixed dose of TXA for patients undergoing simultaneous bilateral TKAs was effective and safe in reducing total blood loss and allogeneic blood transfusion needs without any additional thromboembolic risk. However, TXA administered intravenously did not significantly reduce the hidden blood loss.

Abstract
OBJECTIVE To determine the value of the use of a pneumatic tourniquet in total knee arthroplasty. METHODS Sixty patients were prospectively randomized into 2 groups, one group underwent total knee replacement with a tourniquet (n = 30) and one without (n = 30). Operating time, blood loss, postoperative mean morphine requirement, swelling, ecchymosis, earlier straight-leg raising and postoperative knee flexion were measured in both groups. RESULTS There was no significant difference in the total blood loss between the 2 groups although the intraoperative blood loss was significantly greater in those without a tourniquet. The mean morphine requirement, postoperative swelling, scope of ecchymosis, earlier straight-leg raising and postoperative knee flexion in the patients that had surgery without a tourniquet were significantly better than those with a tourniquet. CONCLUSION Knee arthroplasty operation with the use of a tourniquet has only small benefits on the total blood loss, but hinder in patients' early postoperative rehabilitation exercises.
