Abstract
BACKGROUND AND OBJECTIVE Severe aplastic anaemia (SAA) is a syndrome of bone marrow failure caused by T cell-mediated destruction of haematopoietic stem cells and progenitor cells. Whether patients with SAA should be treated with eltrombopag (EPAG) and immunosuppressive therapy (IST) or IST alone remains debatable. Therefore, we conducted this meta-analysis to compare the efficacy of eltrombopag + IST with that of IST alone in patients with SAA and to assess the difference in the efficacy of eltrombopag in adults and children. METHODS We performed this meta-analysis by retrieving studies that met the inclusion and exclusion criteria from PubMed, EMBASE, and the Cochrane Library up to 1 January 2023. We used a random-effects model to calculate odds ratios (ORs) with 95% confidence intervals (CIs) for primary and secondary outcomes. I(2) statistics were used to evaluate the heterogeneity of the included studies. RESULTS Six studies involving a total of 699 patients were included. In terms of the primary outcomes, our pooled results indicated that patients treated with EPAG + IST had a higher 6-month overall response rate (OR = 2.25; 95% CI, 1.60-3.16; p < 0.00001), a higher 6-month complete response rate (OR = 2.61; 95% CI, 1.82-3.74; p < 0.00001), and a lower 6-month nonresponse rate (OR = 0.32; 95% CI, 0.19-0.52; p < 0.00001). However, there was no significant difference in the rate of 6-month partial response (OR = 0.94; 95% CI, 0.49-1.81; p = 0.85). CONCLUSION This meta-analysis indicated that patients treated with additional eltrombopag for IST may have a higher rate of haematological response.

Peng J, Wang Q, Xu Y, He H
BMC musculoskeletal disorders. 2023;24(1):366
Abstract
PURPOSE To systematically review the studies regarding to the safety, efficacy and application methods of PRP in promoting the talar cartilage repair. METHODS A systematic review was performed by searching PubMed, Web of Science, OVID and EMBASE to identify studies that compared the clinical efficacy of PRP for talar cartilage repair. Main outcome was the American Orthopedic Foot and Ankle Society (AOFAS) score for function and Visual Analog Scale (VAS) for pain was the second outcome. RESULTS A total of 10 studies were included in this systematic review, including 4 randomized controlled trials, 1 controlled trial, 3 case series and 2 cohort studies. Four RCTs were analyzed using meta-analysis. For all outcomes, statistical results favored PRP group (AOFAS MD = 7.84; 95% CI= [-0.13, 15.80], I(2) = 83%, P < 0.01; VAS: MD = 1.86; 95% CI= [0.68, 3.04], I(2) = 85%, P < 0.01). There were almost no reports of adverse events related to PRP intervention. Subgroup analysis showed that whether PRP was used alone or combined with other treatments could result in high heterogeneity but no more specific factors were identified to contribute to this. CONCLUSION PRP is safe and effective for talar cartilage repair. In addition to the standardization of PRP preparation and application, it is necessary to distinguish the effects of PRP used alone or in combination with other treatments. In PRP studies, surgical treatment of talar cartilage repair remains the mainstream. The regulation of PRP in surgical applications are worth exploring. The most relative component is the mesenchymal stem cell because it is the only exposed chondrocyte precursor in the articular cavity whether it is microfracture or cell transplantation. TRIAL REGISTRATION The study was registered in the PROSPERO International prospective register of systematic reviews (CRD42022360183).

Li M, Kang Y, Wang Q, Yan L
Journal of clinical medicine. 2022;11(22)
Abstract
(1) Background: Controversial conclusions have been made in previous studies regarding the influence of autologous platelet-rich plasma (PRP) in the reproductive outcomes of women with repeated implantation failures (RIF) who are undergoing embryo transfer (ET). (2) Methods: This study aimed to evaluate the effect of PRP intrauterine infusion in patients with unexplained RIF, who are undergoing in vitro fertilization (IVF) or intracytoplasmic injection (ICSI), by a systematic review and meta-analysis. (3) Results: A fixed-effects model was used, and 795 cases and 834 controls were included in these studies. The pooling of the results showed the beneficial effect of PRP which were compared with those of the control in terms of the clinical pregnancy rates (n = 10, risk ratio (RR) = 1.79, 95% confidence intervals (CI): 1.55, 2.06; p < 0.01, I(2) = 40%), live birth rates (n = 4, RR = 2.92, 95% CI: 2.22, 3.85; p < 0.01, I(2) = 83%), implantation rates (n = 3, RR = 1.74, 95% CI: 1.34, 2.26; p < 0.01, I(2) = 0%), and positive serum β-HCG 14 days after the ET (n = 8, RR = 1.77, 95% CI: 1.54, 2.03; p < 0.01, I(2) = 36%). However, we did not find that the miscarriage rates indicated a significant difference between the two groups (n = 6, RR = 1.04, 95% CI: 0.72, 1.51; p = 0.83, I(2) = 0%). (4) Conclusions: The findings of this systemic review and meta-analysis suggest that PRP appears to improve the results of IVF/ICSI treatments in the cases of unexplained RIF.

Journal of orthopaedic surgery and research. 2021;16(1):373
Abstract
OBJECTIVE The present meta-analysis was conducted to evaluate the efficacy and safety of the application of tranexamic acid (TXA) in patients undergoing high tibial osteotomy (HTO). METHODS PubMed (MEDLINE), EMBASE, and Cochrane Library were systematically searched for relevant literature from inception until 1 February 2021. A combined searching strategy of subject words and random words was adopted. After testing for potential publication bias and/or heterogeneity, we aggregated variables by using the random-effect model. The primary comparison outcome measures were total blood loss, hemoglobin decrease, drain output, wound complications, thrombotic events, and blood transfusion rate of the TXA group versus control. The meta-analysis was performed using the RevMan 5.3 software. RESULTS A total of 5 studies were included involving 532 patients. The results showed that there were significant differences in the two groups concerning total blood loss (95% confidence interval [CI] - 332.74 to - 146.46, P < 0.00001), hemoglobin decrease on postoperative day (POD) 1, 2, and 5 (POD 1 95% CI - 1.34 to - 0.63, P < 0.00001; POD 2 95% CI - 1.07 to - 0.68, P < 0.00001; POD 5 95% CI - 1.46 to - 0.84, P < 0.00001), drain output (POD total 95% CI - 195.86 to - 69.41, P < 0.00001) and wound complications (RR = 0.34, 95% CI 0.12 to 0.97, P = 0.04). Nonsignificant differences were found in the incidence of thromboembolic events (RR = 0.46, 95% CI 0.09 to 2.41, P = 0.36) and blood transfusion rate (RR = 0.25, 95% CI 0.03 to 2.27, P = 0.22). CONCLUSIONS This meta-analysis of the available evidence demonstrated that TXA could reduce total blood loss, hemoglobin decrease, drain output, and wound complications without increasing the incidence of thromboembolic events in patients undergoing HTO. But there is no obvious evidence that TXA could reduce blood transfusion rates. Further studies, including more large-scale and well-designed randomized controlled trials, are warranted to assess the efficacy and safety issues of routine TXA use in HTO patients.

Front Pharmacol. 2020;11:603
Abstract
Background: The survival of early placement (within 72h after admission) of transjugular intrahepatic portosystemic shunts (early-TIPS) in patients with cirrhosis and acute variceal bleeding (AVB) is controversial. Objectives: We performed a systemic review and meta-analysis to assess whether early-TIPS could improve survival in patients with cirrhosis and acute variceal bleeding. Methods: A systematic search of the literature was conducted in PubMed, EMBASE, and Cochrane Library published before 25 June 2019 for eligible studies that compared early-TIPS with a combination of endoscopic variceal ligation (EVL) and pharmacotherapy in the therapeutic effect in AVB patients. Results: A total of five studies with 1,754 participants were enrolled. The early-TIPS demonstrated a significant improvement in prevention of treatment failure (OR=0.11,95%CI=0.05-0.23), 6-weeks mortality (OR=0.24,95%CI=0.13-0.46), rebleeding within 6 weeks (OR=0.21,95%CI=0.12-0.36), rebleeding within 1 year (OR=0.16,95%CI=0.07-0.36), new or worsening ascites (OR=0.33,95%CI=0.21-0.53), except in encephalopathy (OR=1.29,95%CI=0.996-1.67). For 1-year mortality, a significant prior effect was also observed in early-TIPS (OR=0.64,95%CI=0.46-0.90), and the beneficial effect in Child-Pugh C patients (OR=0.35,95%CI=0.18-0.68) was equal to Child-Pugh B patients (OR=0.34,95%CI=0.25-0.58). No difference in liver transplantation and mortality caused by liver failure was observed. Conclusions: Early covered-TIPS could be recommended for the management of AVB patients in cirrhosis demonstrating a significant improvement in treatment failure, both short- and long-term mortality, rebleeding risk, and new or worsening ascites compared to standard therapy, especially for high-risk AVB patients. It will also apply to patients with Child-Pugh A until solutions to prevent hepatic encephalopathy in future research are found.

Chen P, Huang L, Ma Y, Zhang D, Zhang X, Zhou J, Ruan A, Wang Q
Journal of orthopaedic surgery and research. 2019;14(1):385
Abstract
OBJECTIVE The purpose of this study was (1) to perform a summary of meta-analyses comparing platelet-rich plasma (PRP) injection with hyaluronic acid (HA) and placebo injection for KOA patients, (2) to determine which meta-analysis provides the best available evidence to making proposals for the use of PRP in the treatment of KOA patients, and (3) to highlight gaps in the literature that require future investigation. MATERIAL AND METHODS PubMed, EMBASE, and Cochrane databases search were performed for meta-analyses which compared PRP injection with HA or placebo. Clinical outcomes and adverse events were extracted from these meta-analyses. Meta-analysis quality was assessed using the Quality of Reporting of Meta-analyses (QUOROM) systems and the Oxman-Guyatt quality appraisal tool. The Jadad decision algorithm was also used to determine which meta-analysis provided the best available evidence. RESULTS Four meta-analyses were included in our study, and all of these articles were Level I evidence. The QUOROM score of each included meta-analysis range from 14 to 17 points (mean score 15, maximum score 18), and the Oxman-Guyatt score range from 4 to 6 points (mean score 5, maximum score 7). Three meta-analyses indicated PRP showed more benefit in pain relief and functional improvement than the control group, and the other one suggested no difference between these groups. All included meta-analyses found no statistical difference in adverse events between these groups. In addition, a meta-analysis conducted by Shen et al. got the highest methodological quality score and suggested that PRP provided better pain relief and function improvement in the treatment of KOA. CONCLUSIONS For short-term follow-up (≤1 year), intra-articular PRP injection is more effective in terms of pain relief and function improvement in the treatment of KOA patients than HA and placebo, and there is no difference in the risk of an adverse event between PRP and HA or placebo. LEVEL OF EVIDENCE Level I evidence, a summary of meta-analyses TRIAL REGISTRATION PROSPERO ID CRD42018116168.

Wang HL, Zeng H, Xu MB, Zhou XL, Rong PQ, Jin TY, Wang Q, Zheng GQ
Frontiers in pharmacology. 2019;10:1139
Abstract
Background: Primary intracerebral hemorrhage (ICH) is the most harmful subtype of stroke, but there have yet been no specific proven therapies. Chinese herbal medicine (CHM) has been used for ICH for more than a thousand years; however, currently it is still lacking of available evidence. The objective of this study is to assess the current available evidence of CHM for acute ICH according to randomized controlled trials. Methods: Eight databases were searched from the year of their respective inception to November 2017. Only the studies that assessed at least four domains with "yes" according to the Cochrane risk of bias tool were selected for analysis. All the data were analyzed by using Review Manager 5.3 software. P < 0.05 was considered to be statistically significant. Results: Forty-five studies with 4,517 individuals were identified. CHM paratherapy can improve dependency, neurological function deficit, volume of hematoma, clinical effective rate, and volume of perihematomal edema compared with CHM alone or placebo (all P < 0.05). By contrast, it was not significant for improving the mortality rate of ICH patients (P > 0.05). In addition, adverse events were reported in 16 studies, whereas 29 studies did not mention it. The frequency of adverse events was 70/972 in the trial group and 48/944 in the control group. Conclusion: The present study provided supportive evidence of CHM for improving dependency of ICH and showed generally safety; however, there is still lack of evidence for improving mortality rate, and it opens for further study.

Liu Q, Geng P, Shi, Wang Q, Wang P
International Journal of Surgery (London, England). 2018;54((Pt A):):105-112
Abstract
OBJECTIVE To compare the efficacy and safety of tranexamic acid and aminocaproic acid for reducing blood loss and transfusion requirements after total knee and total hip arthroplasty. METHODS We conduct electronic searches of Medline (1966-2017.11), PubMed (1966-2017.11), Embase (1980-2017.11), ScienceDirect (1985-2017.11) and the Cochrane Library (1900-2017.11). The primary outcomes, including total blood loss, hemoglobin decline and transfusion requirements. Secondary outcomes include length of hospital stay and postoperative complications such as the incidence of deep vein thrombosis and pulmonary embolism. Each outcome is combined and calculated using the statistical software STATA 12.0. Fixed/random effect model is adopted based on the heterogeneity tested by I(2) statistic. RESULTS A total of 1,714 patients are analyzed across three randomized controlled trials (RCTs) and one non-RCT. The present meta-analysis reveals that TXA is associated with a significantly reduction of total blood loss and postoperative hemoglobin drop compared with EACA. No significant differences are identified in terms of transfusion rates, length of hospital stay, and the incidence of postoperative complications. CONCLUSION Although total blood loss and postoperative hemoglobin drop are significant greater in EACA groups, there is no significant difference between TXA and EACA groups in terms of transfusion rates. Based on the current evidence available, higher quality RCTs are still required for further research.

Perioperative blood transfusion and the clinical outcomes of patients undergoing cholangiocarcinoma surgery: a systematic review and meta-analysis
Wang Q, Du T, Lu C
European Journal of Gastroenterology & Hepatology. 2016;28((11):):1233-40
Abstract
Several studies have reported different results on the association between perioperative blood transfusion (PBT) and clinical outcomes for patients undergoing cholangiocarcinoma surgery. So far, no systematic review and meta-analysis have focused on this inconsistent issue. Therefore, we carried out a systematic review and meta-analysis to evaluate the association between PBT and the clinical outcomes of cholangiocarcinoma surgery patients. EMBASE, PubMed, Web of Science, and the Cochrane Library were searched from their inception to 6 April 2016 to evaluate the relationship between PBT and clinical outcomes for patients undergoing cholangiocarcinoma surgery. The pooled hazard ratio (HR) with a 95% confidence interval (CI) was calculated using the Cochrane Collaboration's RevMan 5.3 software. A total of 10 studies (1719 patients) were included in the meta-analysis. Pooled analysis showed that PBT was associated with worse 5-year survival rate (HR=1.67, 95% CI=1.41-1.98, P<0.0001) and median overall survival (OS) (HR=1.45, 95% CI=1.14-1.83, P=0.002) in the patients who underwent cholangiocarcinoma surgery. Subgroup analysis showed that intraoperative blood transfusion was also associated with worse 5-year survival rate (HR=1.95, 95% CI=1.49-2.57, P<0.00001). Intraoperative blood transfusion is associated with poor OS for patients undergoing cholangiocarcinoma surgery because it will increase the risk of death. Postoperative blood transfusion may not be associated with OS. In addition, the relationship between PBT and the postoperative complication rate of cholangiocarcinoma surgery is still unclear.

Guo T, Ren L, Wang Q, Li K
International Journal of Surgery (London, England). 2016;35:187-195.
Abstract
OBJECTIVE To determine the best haemostatic strategy for hysterectomy through a network meta-analysis. METHODS We conducted a systematic literature search of the PubMed, Embase, and Cochrane Library databases and extracted data from randomized controlled trials comparing haemostatic strategies for hysterectomy. Direct comparisons and network meta-analyses were conducted in RevMan and ADDIS. Consistency models were established to identify the differences among different haemostatic strategies, and cumulative probability was used to rank the included strategies. Inconsistencies were also tested using node-splitting models. RESULTS Twenty studies from 16 articles (2 articles contained 3 studies each) comprising 1392 patients were included. Direct meta-analysis showed that the LigaSure (SMD = -1.42 [-2.39, -0.44], P = 0.004), bipolar vessel sealing systems (BVSS) (SMD = -0.35 [-0.66, -0.03], P = 0.03), and pituitrin (SMD = -2.13 [-4.14, -0.13], P = 0.04) applications were effective haemostatic strategies. Based on the network meta-analysis and related subgroup analysis of different surgical procedures, the results showed that the application of pituitrin seemed to be the best haemostatic method for hysterectomy (Rank P = 0.64), especially for vaginal hysterectomy (Rank P = 0.72). The application of LigaSure was the best strategy for abdominal hysterectomy (Rank P = 0.54) but was not effective for laparoscopic hysterectomy (direct comparison with BVSS, MD = -31.39 [-146.61, 83.83], P = 0.59). The node-splitting models test revealed that no significant inconsistencies existed in this research. CONCLUSIONS Pituitrin application seemed to be the most effective haemostatic strategy for hysterectomy and was especially suitable for vaginal hysterectomy. The best method for reducing blood loss in abdominal hysterectomy was the application of LigaSure.
