    • Efficacy and safety of different duration of dual antiplatelet therapy in patients undergoing new-generation drug-eluting stents implantation: a meta-analysis

      Objective To systematically review the efficacy and safety of different duration of dual antiplatelet therapies in patients undergoing new-generation drug-eluting stents implantation. Methods Such databases as MEDLINE, The Cochrane Library (Issue 2, 2015), EMbase, CBM, CNKI and WanFang Data were searched to collect studies on the different duration of dual antiplatelet therapies in patients undergoing new-generation drug-eluting stents implantation from inception to April 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. Results Six trials were included. The results of meta-analysis showed: compared with 12 months dual antiplatelet therapy group, the incidence of bleeding in the 6 months dual antiplatelet therapy group was lower (OR=0.48, 95%CI 0.26 to 0.89, P=0.02). There were no significant differences in incidence of myocardial infarction, all cause mortality, stroke and stent thrombosis between two groups. Compared with 24 months dual antiplatelet therapy group, the incidence of stent thrombosis in the 12 months dual antiplatelet therapy group was higher (OR=2.50, 95%CI 1.13 to 5.61, P=0.02), but the incidence of bleeding in 12 months dual antiplatelet therapy group was lower (OR=0.25, 95%CI 0.07 to 0.89, P=0.03). No significant differences were found in the incidence of myocardial infarction, all cause mortality and stroke between 12 months dual antiplatelet therapy group and 24 months dual antiplatelet therapy group. Conclusions 6 months dual antiplatelet therapy following new-generation drug-eluting stent implantation is relatively more safe and efficacy. There is significant increase of incidence of bleeding in 12 or 24 months dual antiplatelet therapy. Due to the limited quantity and quality of included studies, the above results are needed to be validated by more high quality studies.

    • ANTIBACTERIAL EFFECT OF AUTOLOGOUS PLATELET-RICH GEL DERIVED FROM HEALTH VOLUNTEERS IN VITRO

      Objective The use of autologous platelet-rich gel (APG) is a relatively new technology and a promising treatment method for infections, which is currently being used by a variety of surgical specialties. The mechanism of antibacterialeffect of APG is not yet fully discovered. Subsequent evidence suggests that platelets have multi ple functional attributes inantimicrobial host defense (including the capacity to generate antimicrobial oxygen metabol ites and the antimicrobial peptides) and interact directly with microorganisms, contribute to clearance of pathogens from the blood. To investigate the bacteriostasis of APG against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa in vitro. Methods Platelet-rich plasma (PRP) and platelet-poor plasma (PPP) were obtained from whole blood of 17 healthy donors. APG was prepared by mixing PRP with bovine thrombin in a 10% calcium gluconate solution or bovine thrombin in a 10% calcium gluconate solution and apocynin (APG-APO). Antibacterial effects of APG, PRP, and APG-APO on Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa were evaluated by bacteriostasis assay. Results The culture results showed apparent decrease in the number of Staphylococcus aureus for both APG and APG-APO, which was maximal at first 4 hours and lasted to 24 hours and 8 hours, respectively; showing significant difference (P lt; 0.05) when compared APG with PRP and PPP, however no significant difference at first 8 hours (P gt; 0.05) and significant difference at 12 and 24 hours (P lt; 0.05) when compared APG with APG-APO; showing significant difference at first 4 hours (P lt; 0.05), no significant difference at 6, 8, 12, and 24 hours when compared APG-APO with PRP and PPP (P gt; 0.05). The bacteriostasis rates of APG and APG-APO were 27.36%-52.97% and 18.82%-51.52% against Escherichia coli, respectively; showing no significant difference (P gt; 0.05) when compared with PRP. The bacteriostasis rates of APG and APG-APO were less than 35% against Pseudomonas aeruginosa, showing no significant difference (P gt; 0.05) when compared with PRP; the bacteriostasis rates of PRP were less than 15% against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. Conclusion APG may have potential bacteriostatic effect against Staphylococcus aureus by platelet mediating. Either APG or APG-APO has no obvious bacteriostatic effect against Escherichia coli or Pseudomonas aeruginosa. PRP has no antibacterial activity against Staphylococcus aureus, Escherichia coli or Pseudomonas aeruginosa.

    • Ticagrelor plus aspirin versus clopidogrel plus aspirin on graft patency after coronary artery bypass graft surgery: A randomized controlled trial

      ObjectiveTo compare the effect of aspirin+ticagrelor and aspirin+clopidogrel on graft patency one year after coronary artery bypass grafting (CABG).MethodsA total of 67 patients who received CABG in our department from January 2014 to September 2017 were included in this study (52 males and 15 females). They were randomly divided into a group A (aspirin+clopidogrel) and a group B (aspirin+ticagrelor). There were 34 participants in the group A (28 males and 6 females) and 33 patients in the group B (24 males and 9 females). All patients were invited for clinical follow-up and 64-slice multislice computed tomography angiography (MSCTA) analysis in 1 year postoperatively. Cardiovascular events, bleeding events and other adverse events were followed up.ResultsFour patients were lost to follow-up. Two patients died. A total of 61 patients (48 males and 13 females) completed coronary CTA, and 31 in the group A (25 males and 6 females) and 30 in the group B (23 males and 7 females). The total number of bridged vessels was 156 (59 internal thoracic artery bridges and 97 great saphenous vein bridges), including 79 in the group A (31 internal thoracic artery bridges and 48 great saphenous vein bridges) and 77 in the group B (28 internal thoracic artery bridges and 49 great saphenous vein bridges). Graft patency rate 1 year post CABG was 82.3% (65/79) in the group A and 92.2% (71/77) in the group B (P>0.05). Artery graft patency rate 1 year post CABG was 96.8% (30/31) in the group A and 96.4% (27/28) in the group B (P>0.05). Saphenous vein graft patency rate 1 year post CABG was 72.9% (35/48) in the group A and 89.8% (44/49) in the group B (P<0.05). Multivariable analysis with binary logistic regression showed ticagrelor use reduced graft occlusion (OR=0.282, 95%CI 0.093 to 0.862, P<0.05). There was no significant difference in adverse events between the two groups.ConclusionCompared with clopidogrel plus aspirin, ticagrelor added to aspirin after CABG may enhance the saphenous graft patency without the excess risk of bleeding 1 year post CABG.

      ObjectiveTo investigate the effectiveness of extracorporeal shock wave therapy combined with platelet-rich plasma (PRP) injection in treatment of knee osteoarthritis (KOA) by prospective clinical study.MethodsBetween June 2015 and June 2018, 180 patients with KOA met the inclusion criteria were included in study and randomly allocated to group A (n=60), group B (n=60), and group C (n=60). The patients were treated with autologous PRP intra-articular injection in group A, extracorporeal shock wave therapy in group B, and extracorporeal shock wave therapy combined with autologous PRP intra-articular injection in group C, once a week and 5 times a duration of treatment. There was no significant difference in age, gender, disease duration, side of KOA, and Kellgren-Lawrence grading between groups (P>0.05). The pain and function of knee joint were assessed by visual analogue scale (VAS) score, Lequesne Index score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and knee joint activity before treatment and at 1, 3, and 5 weeks after the first treatment.ResultsThere were significant differences in VAS score, Lequesne Index score, WOMAC score, and knee joint activity between pre- and post-treatment in all groups (P<0.05). VAS score, Lequesne Index score, and WOMAC score gradually decreased with the prolongation of treatment time (P<0.05); but there was no significant difference in knee joint activity between different time points (P>0.05). There was no significant difference in VAS score, Lequesne Index score, WOMAC score, and knee joint activity between groups before treatment (P>0.05); the scores of group C were superior to groups A and B (P< 0.05) at different time points after treatment; while the knee joint activities of 3 groups were similar (P>0.05).ConclusionThe extracorporeal shock wave therapy combined with PRP injection can relieve the pain synergistically for KOA.

    • Current research status of blood routine indexes in predicting severity of acute pancreatitis

      ObjectiveTo summarize the blood routine indexes and predictive systems that can predict the severity of acute pancreatitis (AP). MethodThe recent domestic and foreign literatures on the predictive value of blood routine indexes for the severity of AP were reviewed.ResultsFrom the current research results at domestic and foreign, independent blood routine indexes such as red blood cell distribution width, average platelet volume, hematocrit (TCT), platelet (PLT) count, platelet distribution width, percentage of immature granulocytes (IG%), and some blood routine calculation indexes such as neutrophil to lymphocyte ratio (NLR), PLT to lymphocyte ratio (PLR), red blood cell distribution width to PLT ratio (RPR), neutrophil-monocyte product, and so on, all had different predictive value for the severity of AP. In addition, multiple prediction modes such as blood routine indexes combined with some serological indexes or other scoring systems could also be used to predict the severity of AP. In general, the predictive value of the NLR, IG%, and HCT on the severity of AP had been unanimously recognized by researchers. However, the conclusions of related studies on the predictive values of PLT, PLR, and RPR on the severity of AP were still controversial. ConclusionsAt present, there are a variety of blood routine indexes can be used to predict severity of AP, but their predictive values are different. Further researches are still needed.

    • Correlation between preoperative peripheral blood NLR, PLR, SII and clinicopathological characteristics and prognosis of 101 patients with gastrointestinal stromal tumor

      Objective To investigate the correlation between the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), systemic immune inflammation index (SII) and clinicopathological characteristics and prognosis in patients with gastrointestinal stromal tumor (GIST). Methods The clinicopathological data and blood routine results of 101 patients with GIST who were treated surgically in the General Hospital Western Theater Command PLA from December 2014 to December 2018 were collected retrospectively, samples were obtained to calculate NLR, PLR and SII. The optimal cutoff value of NLR, PLR and SII were evaluated by receiver operating characteristic (ROC) curve. The Chi-square test and t-test were used to analyze the relationship between NLR, PLR, SII and clinicopathological characteristics of GIST. The Kaplan-Meier plots and the log-rank test were used to analyze the influence factors affecting the recurrence-free survival (RFS) of patients with GIST. Multivariate Cox regression analyses was used to identify the independent influence factors affecting the RFS of patients with GIST. Results The preoperative peripheral blood NLR, PLR and SII of patients with GIST were correlated with the tumor site, tumor diameter and modified NIH risk stratification (P<0.05), but not with the mitotic count of tumor cells (P>0.05). Kaplan-Meier plots and log-rank test showed that NLR, PLR, SII, surgical method, tumor site, tumor diameter, mitosis rate and modified NIH risk stratification were the influential factors of RFS in with GIST. The multivariate Cox regression analysis revealed that postoperative whether to accept regular imatinib adjuvant therapy (HR=32.876, P<0.001), modified NIH risk stratification (HR=129.182, P<0.001), and PLR (HR=5.719, P=0.028) were independent influence factors affecting the RFS of patients with GIST. Conclusions Preoperative peripheral blood PLR, NLR, and SII are correlated with clinicopathological characteristics such as the tumor location, tumor diameter and modified NIH risk stratification, and are the influencing factors of postoperative RFS in patients with GIST. PLR is an independent predictor of RFS in patients with GIST.
